Subject: [PATCH 014/388] feat(tracker-resources): GanttView wires
 Sidebar+Canvas+Toolbar with reactive queries

PR 2 read-only Gantt is now end-to-end functional:
- Two reactive queries (issues, milestones)
- buildLayout(issues) -> rows with depth + isSummary
- createTimeScale(zoom, dateRange.from) -> date<->px math
- Summary ranges computed per parent issue from children's date span
- Local zoom state (Day/Week/Month/Quarter) - no ViewletPreference plumbing
- Horizontal scroll via canvas-scroller; vertical scroll moves Sidebar via translate

From 787f2ae6c42b7a34cea28d1e0a385010d24967c3 Mon Sep 17 00:00:00 2001
From: Michael Uray <michaeluray@users.noreply.github.com>
Date: Fri, 15 May 2026 12:33:15 +0000
Subject: [PATCH 015/388] - layout.ts: orphan child issues (parent filtered
 out) now emit as roots - viewlets.ts: register IssueGantt AFTER IssueKanban
 so List stays default - viewlets.ts: drop showColorsViewOption (canvas does
 not honour it yet) - GanttBar.svelte: normalise reversed startDate>dueDate
 ranges

UX:
- GanttSidebar adds Title column with sticky two-column header
- Sticky time-scale header decoupled from milestone strip (layout fix)
- Per-row jump-to-bar arrow (Plane-style) when bar is offscreen
- ResizeObserver initialises viewport on mount and on resize

Milestones as Gantt rows + collapse:
- Milestones group their issues as nested children (depth+1)
- Collapsible toggle per parent row, local collapsedIds Set
- Milestone summary bar uses existing GanttBar with aggregated range

Icon:
- Register tracker.icon.Gantt to #timeline svg (Gantt pictogram)

Tests: 25/25 jest pass; svelte-check 0 errors.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Layout:
- Bigger row height (28→36) and bar font (11→13px) for readability
- Sidebar reworked into flex-column with separate clipped rows region so
  scrolled rows can never paint over the sticky header(layout fix)
- Drag handle between sidebar and canvas (120–600px range)
- ResizeObserver re-syncs viewport on drag/resize/zoom changes

Interaction:
- Vertical gridlines aligned to time-scale ticks (Plane-style)
- Row hover highlights both sidebar and canvas, with rich HTML tooltip
  (issue title + start + due + duration)
- Title click in sidebar dispatches openIssue → showPanel(EditIssue)
- Double-click on canvas bar dispatches openIssue
- Wheel forwarding from sidebar to canvas-scroller (vertical scroll
  works while hovering issue list)
- Pointerdown + drag on empty canvas pans both axes
- Jump-to-bar buttons now use the bar's true left-edge target

Tests: 25/25 jest pass; svelte-check 0 errors.

Subject: [PATCH 017/388] - SVG horizontal-scroll bug: GanttHeader and
 GanttCanvas now render at   totalCanvasWidth (was viewport width), with
 viewBox in scroll-content   coordinates. The sticky header lives in the same
 coordinate system as   the canvas-stack so horizontal scroll no longer clips
 the time-axis. - showPanel uses tracker.component.EditIssue instead of the
 hardcoded   string + 'as any' cast. - Removed unused GanttToolbar.svelte and
 GanttMilestoneFlag.svelte (dead   files since toolbar moved into GanttView
 and milestone flags became   rows).
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Toolbar:
- Time-navigation cluster: ⏮ « Today » ⏭ + native date picker that jumps
  to a specific date. Replaces the lone Today button.

Interaction polish:
- Sidebar wheel forwarding now uses direct scrollTop/scrollLeft mutation
  with deltaMode scaling — same speed as native canvas scroll.
- TodayMarker no longer hides when scrolled offscreen (SVG width handles
  clipping); milestone reference lines render unconditionally for the
  same reason.

Tests: 25/25 jest pass; svelte-check 0 errors.

Subject: [PATCH 018/388] feat(tracker-resources): wire Gantt sidebar toggles
 into Customize-View

- Register two ToggleViewOptions on the Gantt viewlet:
  ganttShowIssueCode (default OFF) and ganttShowTitle (default ON).
  These show up in the standard Customize-View dropdown.
- Drop the per-component settings popover from GanttView; sidebar
  column visibility now reads viewOptions directly.
- Hover tooltip always surfaces the issue code (e.g. OSTRO-31), even
  when the issue-code column is hidden.
- IntlStrings + en/de/es/fr/it/ja/pt/ru/zh/cs translations added.

Subject: [PATCH 019/388] fix(tracker-resources): clip GanttSidebar inside its
 host
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bug: .gantt-sidebar rendered at its natural height (≈ rows × 36px), and
.sidebar-host had overflow:visible, so for many issues the sidebar
visually overflowed gantt-body which in turn made gantt-body's
scrollHeight balloon to the sidebar's natural height. The result was
that scrolling over the sidebar appeared to scroll the page area
instead of just the canvas.

Fix:
- .sidebar-host now overflow:hidden + height:100% + flex-column
- .gantt-sidebar height:100% + flex:1 1 auto so it fills the host
  rather than stretching past it

Verified: gantt-body scrollHeight == clientHeight, only
.canvas-scroller has scrollable content. Wheel-forward over the
sidebar moves canvas-scroller and the sidebar transform together.

Subject: [PATCH 020/388] fix(tracker-resources): unified Gantt scroll
 container (Plane-style sticky)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces the dual-scroller architecture (sidebar + canvas as siblings,
manual wheel-forwarding for the sidebar) with a single .gantt-scroller
that wraps both columns in a CSS grid. Sidebar uses position:sticky
left:0 so it stays at the left edge during horizontal scroll, while the
time-axis header uses position:sticky top:0. Browser handles all wheel
events natively at native speed.

Why: the previous design rendered the sidebar at its natural height
(rows × 36px), which could be much larger than the visible viewport.
overflow:visible on the sidebar host let it bleed past gantt-body and
made the page area appear to scroll. The wheel-forward hack only worked
for synthetic events; in real browsers, wheel events over the sidebar
either scrolled too slowly (deltaMode mismatch) or stopped firing.

Layout (CSS grid, 2 rows × 3 cols):
- (1,1) sticky top+left: corner with column titles
- (1,2) sticky top:     resize-corner (5px gutter)
- (1,3) sticky top:     time-axis header
- (2,1) sticky left:0:  GanttSidebar rows
- (2,2) sticky left:Wpx: vertical resize-handle
- (2,3) normal:         GanttCanvas SVG

overflow:scroll on .gantt-scroller forces both scrollbars to always
render — the user explicitly asked for visible scrollbars (Plane parity).

GanttSidebar drops its scrollTop prop and the transform-based row
positioning; rows now flow naturally inside the scroll container.

Subject: [PATCH 021/388] feat(tracker-resources): + New issue button in Gantt
 toolbar

The standard NewIssueHeader is rendered by the Tracker shell outside the
viewlet. Inside the Gantt view this looked like the action was missing.
Add a prominent + New issue button in the gantt-toolbar that opens
CreateIssue with the current project space pre-selected, matching the
behaviour of NewIssueHeader.

Subject: [PATCH 022/388] chore(tracker): localize Gantt UI strings + minimize
 locale diffs

- Remove "+ New issue" button from GanttView. PR2 stays read-only;
  issue creation lives in PR3 with edit/drag.
- Localize all visible Gantt strings via use:tooltip + Label, no more
  hardcoded English: Today, Jump to start/end, Previous/Next period,
  Jump to date, Issue, Title, Milestone, Start/Target/Due, Expand,
  Collapse, Scroll left/right to bar.
- Add 9 new IntlStrings (GanttToday, GanttJumpToStart, GanttJumpToEnd,
  GanttJumpToDate, GanttPreviousPeriod, GanttNextPeriod,
  GanttScrollLeftToBar, GanttScrollRightToBar, GanttExpand,
  GanttCollapse) on top of the existing GanttShowIssueCode and
  GanttShowTitle.
- Restore all 13 locale files to their PR1 baseline formatting and
  add only the additive Gantt entries (~17 new lines per locale,
  English fallback). ko.json, pt-br.json, tr.json now ship the same
  Gantt keys as the rest.

Tests: tracker-resources svelte-check 0 errors; tracker-assets locale
test pass.

Subject: [PATCH 023/388] feat(tracker-resources): blue plus-only
 NewIssueHeader

User-requested UX consolidation: the same compact "+ New issue" button
should appear above every Tracker viewlet (List, Kanban, Gantt) instead
of the bulky text+dropdown HeaderButton.

- Replace HeaderButton with two stacked Button instances:
  * primary blue circular icon-only IconAdd (newIssue / newProject)
  * regular grey circular IconDropdown with secondary actions popup
- Always visible regardless of viewlet (kind of a tab-bar shortcut)
- showTooltip surfaces the keybinding from the existing tracker action
- Draft indicator stays as small dot on top-right of the plus button

Subject: [PATCH 024/388] fix(tracker-resources): resize handle no longer
 fights canvas pan
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sidebar resize handle and the canvas pointer-pan handler both lived
on the gantt-scroller, so dragging the handle started a canvas pan in
parallel — the result was visible stutter and barely-controllable
resize. Two fixes:

- Add .resize-cell to onCanvasPanStart's element exclusion list so the
  pan never starts when the handle is the pointerdown target.
- The resize-cell's own pointer handlers now stopPropagation +
  preventDefault, so even if a sibling listener picked up the bubbled
  event it would not double-process it. setPointerCapture stays so the
  drag tracks the pointer outside the cell bounds.

Plus the v16 toolbar consolidation:
- Move the always-visible blue + button to IssuesView.svelte (the
  shared wrapper for List, Kanban and Gantt). Single source — no
  duplication per viewlet.
- NewIssueHeader stays as the original HeaderButton-based component;
  inline category-level + buttons in the issue list are unaffected.

Subject: [PATCH 025/388] feat(tracker-resources): sticky-bottom horizontal
 scrollbar (Plane-style)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous architecture put the canvas-stack inside one big
.gantt-scroller with overflow:scroll, so the native horizontal
scrollbar lived at the bottom of the entire scroll content — far
below the viewport once many rows were scrolled past. Noted:
this; Plane uses a separate sticky h-scrollbar at the bottom of the
visible area.

This commit splits the two scroll axes:

- .gantt-scroller now has overflow-y:auto + overflow-x:hidden. It
  carries vertical scrolling for the rows. Vertical native scrollbar
  unchanged.
- A separate .gantt-hscrollbar sits as a sibling at the bottom of
  .gantt-root (always visible regardless of vertical scroll
  position). It contains a thin track of width=totalCanvasWidth.
- The canvas-cell and header-cell become overflow:hidden, with
  inner wrappers translated by -hScroll.scrollLeft. Horizontal scroll
  is therefore controlled by the proxy bar but the visual sync
  matches what native scrolling would do.
- Pan-drag, jump-to-* and all programmatic scrolls now operate on
  the proxy bar instead of the gantt-scroller.
- ResizeObserver watches both scrollers so changes to either side
  re-sync the viewport bounds.

Subject: [PATCH 026/388] feat(tracker-resources): custom DOM scrollbar thumb
 (visible everywhere)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous implementation had the previous v18 sticky horizontal scrollbar still
relied on a native ::-webkit-scrollbar inside an environment where
Huly globally hides scrollbars (\`* { scrollbar-width: none }\`). On
some browsers/OS combinations the bar rendered as a 6px ghost the
user could not see.

This commit replaces the native bar with a DOM-based custom thumb:

- .gantt-hscrollbar contains an .hscroll-shell (position:relative,
  flex:1, min-width:0, overflow:hidden) that fits the viewport width.
- Inside the shell: an .hscroll-track-custom (overflow-x:scroll) is
  the actual scroll-source — its native scrollbar is forcibly hidden
  on both Firefox (scrollbar-width:none) and WebKit (display:none).
  A 1px wide spacer drives its scrollWidth.
- A sibling .hscroll-thumb is absolutely positioned over the shell
  and its left/width are computed from canvasViewportLeft and
  totalCanvasWidth. Pointer drag on the thumb writes back to
  hScrollEl.scrollLeft (and pointermove updates the position
  reactively).
- Click on empty track area page-scrolls 80% of viewport.

Result: a guaranteed-visible 11px tall thumb that follows the
canvas timeline regardless of browser, OS, or Huly's global scroll
styling.

Subject: [PATCH 027/388] feat(tracker-resources): hardened scrollbars + status
 colors + tight date range
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Robustness fix:
- .gantt-hscrollbar is now position:absolute pinned to gantt-root
  bottom (z-index:10) instead of relying on the flex chain to keep
  it visible. .gantt-scroller reserves padding-bottom:16px so the
  bar never paints over the last canvas row.

Vertical custom scrollbar (parity with horizontal):
- Same DOM-thumb pattern: hidden native scroll on .gantt-scroller,
  custom .vscroll-thumb absolutely positioned at the right edge.
- Thumb position derives from scrollTop / vScrollMax; pointer-drag
  writes back to scrollerEl.scrollTop. Auto-hides when content
  fits.

Status-driven bar colors:
- Pull statusStore.byId once into statusCategoryMap; pass through
  GanttCanvas to each GanttBar. Categories map to fills:
  backlog/unstarted -> theme button-default (grey),
  todo -> blue, active -> amber, won -> green, lost -> muted grey.

Tight time-range:
- computeDateRange now pads by exactly one zoom-unit on each side
  (1d / 7d / 30d / 90d) instead of always 14 days.
- totalCanvasWidth = ceil(scaleWidth) only — no longer inflated to
  fill the viewport, which previously stretched the timeline across
  empty quarters with no issues. If the data fits in the viewport,
  the canvas just doesn't horizontally scroll.

Subject: [PATCH 028/388] feat(tracker-resources): status badge column +
 ganttShowStatus toggle

- New StatusBadge.svelte renders a 12px coloured dot per row, mapped
  from the issue's status category via statusStore: backlog grey,
  todo blue, active amber, won green, cancelled muted.
- New ganttShowStatus ToggleViewOption (default ON) joins the existing
  Show-issue-code and Show-title in the Customize-View dropdown.
- Sidebar gains a 22px col-status column rendered before the issue-code
  cell. Milestone rows show a small "MS" tag instead of an issue code.
- Tracker-assets en.json + 12 other locales gain GanttShowStatus
  additively (+1 line per file).

Subject: [PATCH 029/388] feat(tracker-resources): Tracker UI redesign polish
 v27
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implements 8 of the 9 action items from the an external UI review
redesign review. Item 8 (Geist font swap) skipped — would override
Huly's global Inter and is out of PR2 scope.

1. Today-marker date pill: small red rounded label at the top of the
   today line showing "10. May" so the marker speaks for itself.
2. Active-status bars get a stronger fill (#f59e0b amber + white
   text), Won bars green with white text, ToDo bars sky-blue with
   navy text — bars now read at a glance.
3. Sidebar gains a date-range subheader strip ("Feb 2026 – Mar 2027"
   with « » page-nav and click-to-jump-to-today behaviour). Header
   row height grows from 40 to 56px to fit the stacked layout.
4. Hover spotlight: when any row is hovered, non-hovered rows fade
   to 0.55 opacity (external review-style focus).
5. Milestone reference lines shrink from full-canvas dashed lines
   to a tick + filled triangle in the top 14px of the canvas —
   less visual noise behind the bars.
6. Toolbar Unicode glyphs (⏮ « » ⏭) replaced with Huly's own
   ArrowLeft/NavPrev/NavNext/ArrowRight icons; date input wrapped
   in a label with a Calendar icon.
9. Scrollbars slimmed from 14px to 10px tracks with semi-transparent
   thumbs (opacity 0.45 → 0.85 on hover, 1 on drag).

Item 7 (theme-aware bar colors) was already wired via statusCategory
Map in v25 — this commit just verifies the path.

Subject: [PATCH 030/388] feat(tracker-resources): inline-add row in Gantt
 sidebar (PR2.1)

Plane-style: dashed-top-border "+ Add issue" row at the bottom of
GanttSidebar opens the standard CreateIssue popup via showPopup.

- GanttSidebar dispatches `addIssue` from a keyboard- and click-
  accessible row using the existing tracker.string.AddIssue label.
- GanttView wires it to showPopup(CreateIssue, { space, shouldSaveDraft }).
- Row is hidden when no space is available (defensive guard in
  newIssue handler).

Verified on dk3 huly_v7 (gantt-v28): row renders, click opens
"New issue" dialog with Issue title field focused.

Subject: [PATCH 031/388] feat(model-tracker): register startDate + dueDate as
 Issue filters
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds Issue.startDate and Issue.dueDate to the ClassFilters mixin for
tracker.class.Issue. Both attributes are TypeDate, which view-model
already wires to view-resources DateFilter (with built-in range
support), so this is the minimal change to expose date-range filtering
in the Tracker filter dropdown — works in List, Kanban, and Gantt.

NB: deploy of this model change is batched with the PR3 multi-pod
deploy (transactor + workspace + tool image + workspace upgrade);
front:gantt-v28 alone is not enough since the ClassFilters mixin TX
lives in the workspace model store.

Subject: [PATCH 032/388] fix(tracker-resources): hide Gantt h-scrollbar when
 there's no overflow
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GanttView computes hHasOverflow but never gated the bar on it — the
sticky-bottom scrollbar was rendered unconditionally, including in
empty workspaces where it was just visual noise. In addition, when
totalCanvasWidth was barely larger than the track, hThumbWidth could
exceed hTrackWidth and the thumb would visually overflow its container.

Fixes:
- Wrap the .gantt-hscrollbar element in `{#if hHasOverflow}` so it
  disappears in the no-overflow case.
- Clamp the rendered thumb width to `Math.min(hThumbWidth, hTrackWidth)`
  to defuse the degenerate over-track case.

in Playwright: empty workspace no longer renders the scrollbar.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Resolve four pre-existing eslint errors that block the CI formatting job:
- GanttCanvas.svelte: split the milestone null-guard into nested {#if}
  blocks (prefer-optional-chain) — a naive optional chain would bypass
  the strict null check when range is null.
- GanttCanvas.svelte / GanttSidebar.svelte: convert void-returning
  short-circuit handlers to block-body arrows (no-confusing-void-expression).
- layout.test.ts: drop the non-null assertion in favour of optional
  chaining on the assertion (no-non-null-assertion).

The drag-controller reducer only accepted mousedown-bar from hover-bar
state, but no DOM event ever transitioned idle → hover-bar (we never
wired the mouseenter-bar event from GanttBar to the reducer). The hover
state was dead code, and the first mousedown on a freshly-rendered
bar was silently dropped — Playwright integration test surfaced this.

Fix: reduceFromIdle accepts mousedown-bar directly with the same
edge-discriminator logic as reduceFromHover. Real users always go
through hover-bar first (mouseenter fires before mousedown), but
synthetic event dispatch and re-render edge cases can skip it.

Adds 2 tests:
- mousedown-bar from idle → dragging-body
- mousedown-bar (edge=left) from idle → resizing-left

Subject: [PATCH 053/388] feat(tracker-resources): slim Gantt context menu +
 fix pan-grip collision
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. Context menu is too tall (~19 entries from auto-resolved Huly
   actions). Restructured via includedActions allow-list to 9
   curated entries that make sense for a Gantt bar:
   - Open (Edit issue)
   - Status / Priority / Assignee (existing actionPopup submenus, ›)
   - Set start date / Set due date
   - Copy issue ID / URL
   - Duplicate / Delete

   Component, Milestone, Labels, SubIssue, SetParent, Relations,
   Move-to-project and time-report stay accessible from the standard
   List/Kanban menu but are hidden from Gantt's right-click.

2. Unscheduled-drag-grip in the sidebar shared pointerdown with the
   canvas pan handler. Pan would start before the grip's
   mousedown|stopPropagation fired, swallowing the drag.

   Extended onCanvasPanStart exclusion: now also bails on
   .sidebar-cell, .drag-grip, .resize-handle. The grip's pointerdown
   no longer triggers a stray pan.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

User UX feedback 2026-05-11: the allow-list approach hid Open (Edit
issue) because tracker registers a custom Open action for
tracker.class.Issue with an auto-generated ID, and it also hid
Set parent issue / Add sub-issue which the user explicitly needs to
manage issue hierarchy from the Gantt.

Switch from includedActions to excludedActions. Hide only the
genuinely noisy entries for a Gantt right-click: Component,
Milestone, Labels, CopyIssueTitle, Relations, NewRelatedIssue,
EditRelatedTargets, MoveToProject, CopyAsMarkdownTable, UnsetParent.

Result: Open / Status / Priority / Assignee / Set start date /
Set due date / Add sub-issue / Set parent issue / Copy ID / Copy URL
/ Duplicate / Delete remain — 12 entries instead of 18, with the
expandable submenus (Status, Priority, Assignee ›) keeping the
visible menu compact.

Subject: [PATCH 055/388] feat(tracker): Gantt Hierarchy submenu + EditIssue
 parent + header supra labels
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

User requirements 2026-05-11:

1. Restructure Gantt right-click menu: "Sub-issue & Parent" as a single
   collapsed Hierarchy ▸ submenu containing
   - Set parent issue…
   - Add sub-issue
   - Link existing as sub-issue…   (NEW)
   The old flat SetParent + NewSubIssue entries are hidden from the
   parent menu (excludedActions) so the Gantt context menu stays compact.

2. EditIssue panel: add a "Set parent issue…" button visible when the
   issue has no parent — previously this was only reachable via right-
   click context menu, not from the open issue itself.

3. SubIssues panel: add a "Link existing as sub-issue" button next to
   the existing "Add sub-issue" button so the user can attach an
   already-existing issue without first opening it.

4. GanttHeader two-row labels (user feedback: "year/month above"):
   - day view:    month name above day number
   - week view:   year above Wnn
   - month view:  year above month name (was entirely missing)
   - quarter view: year split out above Q1/Q2/… (was side-by-side
     "Q1 2026" — visually noisy at dense zoom)

   Supra-label renders only at segment boundaries (1st of month, first
   week of year, January, Q1) so it doesn't repeat in every column.
   3 new jest tests cover day/week/quarter supra cases.

- Hierarchy UiAction missing required `action` field — added no-op
  (Menu.svelte routes the click via `component:` when present).
- dragging-unscheduled no longer shifts existing descendants — the
  synthetic "today" origin would have shifted them by a wildly
  unrelated delta. Unscheduled-drag now only commits the parent.
- LinkSubIssueActionPopup: full ancestor + transitive descendant
  ignore set so the picker can't create cycles (BFS over the
  parents[0].parentId edge, matching scheduler.descendantsWithDates).
- releasePointerCapture now guarded by hasPointerCapture(pointerId)
  to avoid InvalidStateError when a pointerup bubbles from an
  excluded child (resize-handle, drag-grip).
- openSetStartDate (context menu) now surfaces commit failures via
  NotificationSeverity.Error, matching commitDrag's error handling.
- i18n: drag-grip tooltip and duration tooltip pulled out of hardcoded
  English into tracker.string.GanttDragToSchedule + GanttDurationTooltip.

New files:
- plugins/tracker-resources/src/components/LinkSubIssueActionPopup.svelte
- plugins/tracker-resources/src/components/gantt/GanttHierarchySubmenu.svelte

i18n: 5 new keys (Hierarchy, LinkExistingSubIssue, SetParentIssueLabel,
GanttDragToSchedule, GanttDurationTooltip).

Subject: [PATCH 056/388] feat(tracker-resources): Gantt select-first drag +
 confirm popup + summary-bar interactivity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

User UX requirements 2026-05-11:

1. Click-to-select gate: a bar must be clicked once to become "selected"
   (solid blue outline, .bar.selected) before the next mousedown
   actually starts a drag/resize. Prevents accidentally dragging an
   issue while panning the canvas horizontally — earlier feedback was
   that fast horizontal pans would catch a bar by mistake. Plane-style
   UX. Clicking the canvas background clears the selection.

2. Confirmation popup before commit: GanttConfirmCommitPopup shows a
   "Move X to Y – Z?" / "Change X to Y – Z?" dialog with Cancel/Apply
   buttons. Two independent ViewOption toggles (Customize-View → Display)
   gate whether the popup appears:
     - ganttConfirmMove   (default-on) — drag-body
     - ganttConfirmResize (default-on) — resize-left/right
   Saves to the same per-viewlet option store as ganttShowStatus, so
   each user gets their own preference. Skip the popup entirely when
   the preview is unchanged (zero-delta drag).

   sub-issues it renders as the MS-Project claw rather than a regular
   rect. Previously the claw had no mousedown/contextmenu, so commitDrag's
   parent-pulls-children path was unreachable from the UI. A transparent
   `summary-hit` rect now spans the claw and wires the standard
   onBarDown / onBarContextMenu handlers, plus the two resize-handles.
   Milestone summaries (issueObj === undefined) stay read-only.

- Split GanttConfirm{Move,Resize} setting label from dialog title.
  New keys: GanttConfirmMoveTitle = "Move issue?", GanttConfirmResizeTitle
  = "Change issue dates?". Setting labels remain "Confirm before moving an
  issue" etc.
- Drop unused GanttClickToSelect string.
- New jest suite `link-sub-issue-cycle.test.ts` (6 tests) fences the
  ancestor/descendant/self/cycle ignore logic so future refactors can't
  silently regress cycle protection.

Deploy:
- models/tracker + models/all rebuilt to ship the new ViewOption keys.
- front/transactor/workspace/tool images at gantt-v35.
- Workspace upgrade applied to all 3 dk3 workspaces — toggles appear in
  Customize-View → Display.

Subject: [PATCH 057/388] fix(tracker-resources): Gantt parent-drag truth
 source + canvasX offset + a11y roles
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

per explicit user preference for both select-first + confirm-popup
default-on):

1. Parent-drag now shifts the FULL descendant tree, not just children
   that happen to be in the view's filtered `issues` array. Previously
   a Tracker filter that hid some sub-issues caused them to stay at
   the old date while their parent moved — silent tree drift. commitDrag
   and shiftFocused both now run `client.findAll(tracker.class.Issue,
   { space: issue.space })` to query the full space before walking
   descendantsWithDates. One extra query per commit, no impact on drag-
   interactive frame rate.

2. computeCanvasX (unscheduled drag) now offsets by sidebarWidthPx +
   5 px instead of just sidebarWidthPx. The 5 px is the resize-cell
   column between sidebar and canvas (.resize-cell). The hscrollbar
   has always used this offset (style="padding-left: {sidebarWidthPx +
   5}px"); unscheduled-drag was the only consumer that missed it,
   causing drops to land a few pixels off at high zoom.

3. A11y: the 6 interactive <rect>s on GanttBar (regular + summary +
   resize handles, both branches) now carry role="button",
   tabindex="-1", and aria-label so screen readers announce them as
   actionable. The a11y-click-events-have-key-events warning is
   suppressed per-rect with svelte-ignore plus a banner comment
   explaining that keyboard support lives at the GanttView level
   (Tab/ArrowLeft/Right). 94 → 88 warnings.

Tests: 5 suites / 60 passed.

friction observation about select-first + confirm-popup left as-is
per explicit user preference, the parent-drag performance note is a
future-large-space concern):

1. .settings-btn / .settings-popover removed from GanttView.svelte.
   They were leftover from an earlier custom-popover prototype that
   was replaced by Huly's standard ToggleViewOption pattern in PR2;
   the CSS was orphaned. Drops 4 svelte-check warnings.

2. Resize handle ARIA labels were hardcoded English ("Resize start" /
   "Resize end"). Now translated via tracker.string.GanttAriaResizeStart
   and GanttAriaResizeEnd. Translation resolves async on themeStore
   language change; falls back to the English default until resolved.

84 warnings (was 88).

Subject: [PATCH 059/388] chore(tracker-resources): remove internal review
 markers from inline comments

Strips reviewer-attribution markers ('review-N <date>') from source-code
comments. Comments are kept and rephrased as 'review note' so the noted
constraint or hidden invariant survives, only the internal attribution
is dropped.

Subject: [PATCH 060/388] fix(tracker-resources): resolve eslint errors in
 gantt edit components
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

handleCanvasMouseUp is async; passing it directly to window
add/removeEventListener triggers @typescript-eslint/no-misused-promises
(Promise returned where a void return is expected). Introduce a single
stable void-returning wrapper (onWindowMouseUp) used at all three sites
so add and remove still reference the same listener object — a per-call
arrow wrapper would leak the listener. The mouseup commit stays
fire-and-forget with its existing internal error handling.

Subject: [PATCH 062/388] i18n(tracker-assets): sync ru.json keys with en.json
 (gantt pr3a)

lang.test enforces en/ru structural parity. Gantt feature keys added to
en.json were missing in ru.json; filled with the en value as a
placeholder pending translation (Huly convention). No existing ru
translations changed.

Subject: [PATCH 063/388] =?UTF-8?q?fix(tracker-resources):=20Gantt=20bar?=
 =?UTF-8?q?=20selection=20=E2=80=94=20cursor,=20visual,=20single-marked=20?=
 =?UTF-8?q?invariant?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- cursor: pointer when editable+unselected, grab when selected,
  grabbing during active drag (same state machine for summary claw)
- .bar.selected: 3px stroke + stronger glow, paint-order stroke fill
  so the armed state is unmistakable on every status fill color
- .bar.focused: 1px dashed (was 2px solid) — visually distinct from
  .selected so the two states never look identical
- handleBarMouseDown syncs focusedIssueId to selectedIssueId on
  first-click and onBackgroundClick clears both; eliminates the
  'multiple bars marked' visual where Tab-focus + click-select
  highlighted two bars simultaneously
- resize handles only render when the bar is selected (avoids
  accidental edge-grabs on unarmed bars; minimal surface for the
  ew-resize cursor)

User feedback 2026-05-11 from dk3 deployment: single click did not
visibly mark the bar and multiple bars appeared selected at once.

Subject: [PATCH 064/388] =?UTF-8?q?fix(tracker-resources):=20Gantt=20bar?=
 =?UTF-8?q?=20selection=20=E2=80=94=20reactive=20prop=20helpers?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous isEditable/isFocused/isSelected functions hid their
underlying state dependencies (editableIssueIds Set, focusedIssueId,
selectedIssueId) from Svelte's template dependency tracker. The
template binding 'editable={isEditable(row.issue._id)}' only
re-evaluated when its visible references (isEditable function ref
and row.issue._id) changed — never when the underlying Set or string
mutated.

Initial pass: editableIssueIds is empty, bars render editable=false.
Async canEditIssue loop populates the Set, but the template never
re-runs the binding. GanttBar.onBarDown early-returns on !editable,
so click/drag/resize all silently failed — user reported clicking a
bar did nothing.

Same staleness applied to selectedIssueId and focusedIssueId: even
after handleBarMouseDown set selectedIssueId, the binding never
re-evaluated, so the .selected class never reached the DOM.

Fix: promote the three helpers to '$:' reactive declarations.
Svelte now sees the underlying state as a dependency and reassigns
the function on every relevant change, which invalidates the
template binding and re-evaluates the prop.

Verified end-to-end in Playwright on dk3 huly_v7 stack (gantt-v39):
- 5 bars all editable=true after createQuery + canEditIssue loop
- single click sets exactly one .selected (and synced .focused)
- click on another bar deselects the previous one
- click on background clears both selected and focused
- drag from selected bar enters .active-drag with cursor=grabbing
- mouseup leaves active-drag state cleanly
- resize handles only render when the bar is selected

- canEditMilestone() helper in utils.ts, mirrors canEditIssue's
  guest-vs-member logic (non-guests can edit, guests cannot)
- Milestone label cell in GanttSidebar gets class='cell-title clickable'
  + role='link' + on:click → openMilestone, matching the issue row
- New openMilestone event on the sidebar dispatcher, threaded through
  GanttView.onMilestoneOpen → showPopup(EditMilestone, …)

User feedback 2026-05-11: milestones in the Gantt sidebar were a plain
non-interactive label; only issues opened on click. PR3.2 brings the
sidebar to parity. Canvas-bar edit-mode parity for milestones (drag /
resize) is deferred to PR3.3 — that requires a DragState refactor
across 5 files to accept both Issue and Milestone payloads.

Subject: [PATCH 066/388] fix(tracker-resources): Gantt openMilestone resolves
 full Milestone before showPopup

EditMilestone expects 'object: Milestone' and reads object.label /
status / dates synchronously on mount. LayoutRow.milestone carries
only a MilestoneMarker (compact view), so passing it directly threw
'Cannot read properties of undefined (reading label)'.

Sidebar now dispatches milestoneId; GanttView resolves to the full
Milestone from its milestones query before showPopup.

DragState / DragEvent refactor: 'issue: Issue' becomes 'target: DragTarget'
where DragTarget is a discriminated union { kind: 'issue', doc: Issue } |
{ kind: 'milestone', doc: Milestone }. The reducer stays doc-agnostic —
it only operates on originStart / originEnd / cursor deltas, with the
target threaded through unchanged. Renamed originDue → originEnd and
previewDue → previewEnd to reflect the doc-agnostic semantics
(Milestone.targetDate plays the same role as Issue.dueDate).

mousedown-bar now carries explicit originStart / originEnd captured at
the dispatch boundary so the reducer doesn't need to know which field
on target.doc to read.

Milestone rendering (brainstorm decision A): bars are emitted on
milestone rows only when startDate is set. The synthetic children-
aggregate summary-claw is dropped from milestone rows — the milestone
IS the milestone, not its assigned-issues range. Open-ended milestones
(startDate null) remain represented only by the diamond on the top
strip.

Cascade on milestone body-drag (brainstorm decision B): all assigned
issues plus their descendants shift by the same delta. Resize doesn't
cascade — only the milestone bounds change. Issue-cascade (parent →
descendants) is unchanged.

commitDrag now branches by state.target.kind:
- Issue: startDate / dueDate update + descendant cascade (existing).
- Milestone: startDate / targetDate update + assigned-issues cascade.

editableIssueIds Set now holds both Issue and Milestone _ids; the
async permission loop checks canEditIssue or canEditMilestone for
each. milestonesById Map (built reactively from milestones query)
gives GanttCanvas the full Milestone doc to wrap in a DragTarget at
mousedown time.

Tests updated for new field names; 2 new test cases cover milestone
mousedown + resize-right reducer behavior.

Resize-overlay and Sidebar drag-state probes also renamed.

Subject: [PATCH 068/388] feat(tracker-resources): Gantt pan from unselected
 bars
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the user mouses-down on a bar that isn't currently selected, treat
the gesture as a canvas pan (same as click+drag on empty space) instead
of swallowing the drag. The bar still receives its mousedown — the
click-to-select gate still arms selectedIssueId — but the parallel pan
allows the user to scroll horizontally / vertically from the same
gesture.

Selected bars stay excluded so PR3's second-click drag/resize still
fires; otherwise the bar would never move once armed.

User feedback 2026-05-11: previously click+drag on an unselected bar
did nothing visible (selectedIssueId was set but the user wanted to
scroll the canvas).

Subject: [PATCH 071/388] feat(tracker-resources): predecessor-format helpers
 (PR4a)

- kindCode / kindFromCode: round-trip between long-form 'finish-to-start'
  (persisted) and two-letter display codes 'FS' (notation only).
- signedLag: '+2d' / '-1d' / '' (zero) for lag display.
- formatPredecessors: filter relations by target, join 'XXkindLag' tokens.

Subject: [PATCH 078/388] fix(tracker-resources): drag-controller no stale
 target leak (PR4a)

Spread-based return in reduceFromConnector copied target field from
connector-target-hover state into the returned connector-drawing
object. TypeScript permits this excess-property leak through
spreads. Replaced with explicit construction and strengthened the
back-to-drawing test to assert 'target' is absent.

 stroke-dasharray:0 not :none (PR4a)

'none' is not a valid stroke-dasharray value; browsers fall back to
solid silently. Use the canonical '0' reset so the CSS is portable.

Subject: [PATCH 084/388] feat(tracker-resources): GanttBar hover state +
 connector dot mount (PR4a)

- Local `hovered` flag, surfaced via barHover event for hover-emphasize.
- ConnectorDot mounts only when editable && hovered && issue-target,
  excluding milestone and summary-claw bars from connector dragging.

Subject: [PATCH 085/388] fix(tracker-resources): GanttBar isMilestoneSummary
 use dragTarget (PR4a follow-up)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PR3.3 renamed export issueObj → dragTarget but left this $: block
referencing the now-undeclared issueObj. The expression always
evaluated true (undefined === undefined), so isMilestoneSummary
collapsed to isSummary and parent-issue summary claws lost their
hit-rect. Replace with the dragTarget-discriminated check.

- IssueRelation live query (\$or both directions, scoped by space).
- hoveredIssue / hoveredEdge state + connectedIds reactive derivation.
- Connector reducer handlers (down/move/up); mouseup branches:
  · drawing without target → idle (drag cancelled).
  · target-hover → wouldCreateCycle gate → addCollection or error toast.
- showPredecessors ViewOption threaded into GanttSidebar.
- handleOpenEditor resolves canEdit from canEditIssue(sourceIssue) and
  showPopup(DependencyEditor, ...).

Subject: [PATCH 089/388] fix(tracker): de-duplicate 13 PR4a i18n keys from
 base namespace

Task 1 placed the same 13 keys in both plugins/tracker/src/index.ts AND
plugins/tracker-resources/src/plugin.ts. mergeIds() in the tracker-resources
plugin then threw 'identify overwrites DependencyKindFS for tracker:string'
during workspace upgrade (tool image bundle load).

The keys are UI-only (DependencyEditor labels, predecessor column,
cycle-toast, ViewOption label). Following the existing convention
(e.g. GanttShowIssueCode is in tracker-resources only, GanttDragFailed
is in tracker only), the dependency keys all belong in
tracker-resources/src/plugin.ts. Removed from the base tracker namespace.

 empty visibleIssueIds (PR4a)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CockroachDB adapter rejects {$in: []} with 'unsupported comparison
operator: <string> = <string[]>' which surfaces as an error toast and
blocks the entire Gantt render. Empty array also semantically means
'no relations possible' — set relations = [] and skip the query
until issues load.

Subject: [PATCH 091/388] fix(tracker-resources): drop $or relationQuery,
 filter client-side (PR4a)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Huly/CockroachDB adapter doesn't translate top-level $or — it
serializes the operator as a JSONB path (`data#>>'{$or}'`) and crashes
with 'unsupported comparison operator: <string> = <string[]>'.

Query the entire space's relations and let GanttDependencyLayer filter
client-side via barRects (only relations whose endpoints are in
visible barRects render). Relations are typically sparse so the
performance cost is negligible. predecessor-format does its own
client-side filter.

From f6fa3c47e41979ddaad96aa9af0498ad6e85aa11 Mon Sep 17 00:00:00 2001
From: Michael Uray <michaeluray@users.noreply.github.com>
Date: Fri, 15 May 2026 12:53:24 +0000
Subject: [PATCH 098/388] feat(tracker-resources): adaptive Gantt time-scale +
 optimistic dependencies

- viewport.computeAdaptivePxPerDay stretches the time-scale when the
  data range is narrower than the visible canvas so the right side
  fills correctly. New unit test covers the stretch + identity cases.
- createTimeScale accepts an optional pxPerDayOverride for the
  adaptive path (default falls through to ZoomLevel-derived value).
- Optimistic dependency creation: GanttView prepends the new
  IssueRelation to a local list right after addCollection() so the
  arrow renders before the live query roundtrip. Rolled back on
  commit failure and de-duplicated when the canonical doc arrives.
- Connector-dot moves to the bar's bottom-right corner with a 12px
  outset + 10px hit area, plus a fallback native pointer-listener
  registered at document level (covers shadow-DOM / portal edge cases
  where Svelte's event-forwarding path doesn't surface mousedown).

Subject: [PATCH 099/388] fix(tracker-resources): inline gantt live-bezier
 reactive deps

Wrapping the live-preview path computation in livePath() hid dragState
from Svelte's reactivity tracker, so the bezier between the connector
dot and the cursor never redrew while the user dragged. Inline the
condition into the $: block so dragState.kind, dragState.originPx,
and dragState.cursorPx are all visible direct dependencies.

- Clarify FS gap-preservation rationale (Decision D 'Respect Links' /
  no auto-tightening), explain why max(snap, preserve) and why only FS
  needs it
- Add @remarks to detectCycle noting recursive DFS depth assumption

From d25cd9a4c9bcd5a4dc1923761e0979e5fcae7a59 Mon Sep 17 00:00:00 2001
From: Michael Uray <michaeluray@users.noreply.github.com>

Subject: [PATCH 116/388] fix(tracker-resources): PR4b keep drag preview alive
 while cascade popup is open
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The pointerup wrapper at line 612 unconditionally reset activeDrag to
idle BEFORE entering commitWithCascade — so the dragged bar visibly
sprang back to its origin while the ConfirmCascadePopup was on screen,
making the user think their drag was discarded.

Defer the idle-reset for cascade-eligible issue drags to either:
  - the popup resultHandler (commit -> idle after .finally; cancel ->
    idle immediately so the bar springs back), or
  - the no-popup exit paths (alt-bypass commit, no-cascade direct
    commit) which now set idle themselves before returning.

Legacy paths (milestone, dragging-unscheduled, askConfirm wrapper)
continue to reset early — their bar-preview lifecycle is unchanged.

Subject: [PATCH 117/388] feat(tracker-resources): show Gantt IssueRelations in
 issue editor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a Dependencies panel to the EditIssue ControlPanel side that
lists every IssueRelation touching the open issue — both incoming
(this issue is the successor) and outgoing (this issue is the
predecessor). Rows show the kind code (FS/SS/FF/SF) with optional
lag, a direction arrow, and the other issue's identifier + title.

Clicking a row opens the same DependencyEditor popup the Gantt
arrows use, so the user can edit kind/lag or delete the relation
without leaving the issue detail view.

Implementation uses two separate live-queries (attachedTo == issue
and target == issue) because the CockroachDB adapter doesn't
translate top-level $or — same workaround the Gantt view uses for
its space-wide relations query.

Subject: [PATCH 118/388] fix(tracker-resources): always show Dependencies
 section + ganttDebug hook

- IssueDependenciesPanel now always shows the 'Dependencies' label;
  empty state renders the existing NoPredecessors message so the user
  can confirm at a glance whether the live-query returned 0 or N
  relations. (User couldn't tell from prod whether the panel was
  missing or just empty.)
- Expose window.__ganttDebug.activeDrag for live diagnosis of the
  bar-springs-back regression. Removed before upstream PR.

Subject: [PATCH 119/388] feat(tracker-resources): PR4b popup polish + legacy
 confirm parity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- ConfirmCascadePopup: widen label column to 220px, clip label text
  with SVG clipPath so long titles cannot overlap the timeline bars.
  Add vertical separator between label and timeline.
- ConfirmCascadePopup: add color legend below timeline explaining
  primary (indigo) / push-successor (amber) / pull-predecessor (violet)
  + light=original / solid=new shading. 4 new i18n keys.
- GanttView: extend 'bar stays at drag position while popup is open'
  semantics to the legacy GanttConfirmCommitPopup path (milestone +
  dragging-unscheduled). Bar springs back ONLY after the user clicks
  Cancel or the commit completes — never preemptively.
- Remove temp window.__ganttDebug instrumentation.

Subject: [PATCH 120/388] fix(tracker-resources): PR4b svelte-check +
 type-narrowing fixes

1. svelte-check 0 errors (was 5):
   - GanttView line 634 cascadeEligibleIssue: drop redundant
     state.kind !== 'idle' / !== 'hover-bar' checks that TS flagged as
     never-overlapping
   - askConfirm + commitDrag: narrow DragState via explicit kind
     positive-check instead of negative-check so .target is type-safe

2. activeDrag preview release timing:
   - Remove unconditional activeDrag.set({kind: 'idle'}) after
     commitDrag in handleCanvasPointerUp. Cascade path hands off to
     popup resultHandler; legacy paths (milestone, dragging-unscheduled)
     now self-release at the end of their commitDrag branches.

3. simulateCascade permission check covers primary edits:
   - Iterate over both primary AND shifts when building lockedIssues.
     Parent-drag primary array can contain descendant children that the
     user may not be allowed to edit individually.

4. IssueDependenciesPanel canEdit fallback:
   - Drop the optimistic '? issue : fall back to viewer' permission
     guess for incoming rows. Open editor read-only when the
     attachedTo (predecessor) hasn't been resolved yet by the live
     query.

5. ConfirmCascadePopup keyboard focus:
   - Focus the inner <button> element via querySelector('button'),
     not the wrapper div. Wrapper-div focus was ineffective for
     Enter/Space activation.

Subject: [PATCH 121/388] fix(tracker-resources): PR4b permission check before
 no-cascade return

the shifts.size === 0 early-return, so a parent-drag of an editable
parent with a non-editable child and no external successors would
silently commit the child's date too.

Move the permission check above the no-cascade exit. New test 18
asserts the bug: Parent + locked Child as primaryEdits, zero
relations -> result must be permission-denied, not no-cascade.

Subject: [PATCH 126/388] feat(tracker-resources): PR5 critical-path UI wiring
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. CP algorithm: single project finish . Drop per-component
   approach. Standard CPM: one project = max(EF) across all sinks.
   Isolated issues with earlier EF get positive slack, not 0. Test
   'two unrelated issues' updated to assert this.

2. UI wiring  — edits to existing
   files instead of creating GanttToolbar that doesn't exist:
   - GanttView reads ganttCriticalPath / ganttSlackColumn from
     viewOptions read-only; user toggles via Customize-view panel.
   - GanttCanvas forwards criticalSet/criticalRelations/
     violatedRelations/cpSlack/showCriticalPath.
   - GanttBar uses real vars (x, barY, w, barH). Critical bars get
     red border + 18%-opacity red overlay. Slack glyph (light-grey
     trailing rect) on non-critical bars when CP on.
   - GanttDependencyArrow: critical=solid-red, violated=red-dashed.
   - GanttSidebar adds slack-column cell with 'Nd' / 'CP' badge.

3. CP recompute debounced 200ms; cycle banner throttled 60s.

Subject: [PATCH 127/388] feat(tracker-resources): PR6 export + keyboard
 shortcuts + DE i18n

PR6 'polish' wrap-up:

1. PNG export (lib/exporter.ts):
   - exportGanttSvgToPng(svg, opts) serializes the SVG with inline
     computed styles, rasterises through <img src=data:> and a
     canvas at devicePixelRatio scale, returns a PNG Blob.
   - downloadBlob() triggers a browser download.
   - GanttView wires a keyboard shortcut 'E' / 'e' to capture the
     visible .gantt-canvas SVG and save as 'gantt-<YYYY-MM-DD>.png'.

2. Keyboard shortcuts (GanttView onKey):
   - +/= zoom in (cycle day -> week -> month -> quarter)
   - -/_ zoom out
   - ? opens GanttHelpPopup with the full shortcut list
   - E exports to PNG
   - All shortcuts are scoped to the Gantt root via the existing
     containerEl.contains(document.activeElement) gate so global
     bindings aren't hijacked.

3. GanttHelpPopup.svelte: modal listing all 8 shortcuts (drag, zoom,
   help, export, Esc, Alt-bypass). Esc or ? dismisses.

4. German translations:
   - Replaced the 13 English placeholder values in de.json for
     GanttShow*/GanttToday/GanttJumpTo*/GanttScroll*/GanttExpand/
     GanttCollapse with proper translations.
   - Added 49 new DE keys covering PR3 drag/confirm, PR4a dependencies,
     PR4b cascade simulation + popup, PR5 critical path + slack, PR6
     export + help.

4 new i18n keys in plugin.ts (GanttHelpTitle/GanttHelpEsc/GanttExport/
GanttExportFailed) + matching EN values. svelte-check 0 errors.

+ * The Gantt view renders into an `<svg class="gantt-canvas">` overlaid on
+ * the sidebar (`<div class="sidebar-rows">`). Server-side rasterization
+ * would require headless Chromium; we instead serialize the live SVG,
+ * apply inline computed styles (so theme colours and fonts survive
+ * outside the document's `<style>` cascade), draw it to an HTMLCanvas at
+ * the user's chosen device-pixel-ratio scale, and `toBlob()` the result
+ * as PNG. The whole pipeline is synchronous-ish (one image.onload await)
+ * and runs entirely in the user's browser — no upload, no extra round-trip.
+ *
+ * Limitations:
+ *   - SVG `<foreignObject>` content (rare in Gantt) is rasterised by the
+ *     browser using its own font fallbacks; results may differ slightly
+ *     from the on-screen rendering.
+ *   - Custom CSS that targets pseudo-elements (`::before`, `::after`) is
+ *     not serialized — Huly's Gantt does not use them.

Subject: [PATCH 128/388] fix(tracker-resources): PR5 critical-path topoSort
 guard + destroy timer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. GanttView.onDestroy clears the pending cpDirtyTimer:
   - PR5 schedules the critical-path recompute via setTimeout with a
     200 ms debounce. If the view unmounts while a recompute is queued,
     the timer fires after the reactive store handles are torn down —
     dangling write + potential late banner. clearTimeout on destroy
     fixes both.

2. critical-path topoSort in-degree guard:
   - inDegree was incremented whenever the relation's target is in the
     scheduled set, regardless of the source. If a source ref isn't in
     the set the target's in-degree would stay positive forever (the
     source is never dequeued) and the target would silently drop from
     the topological order. The caller passes activeRels (filtered to
     both-endpoints-scheduled), so the bug is mitigated in practice,
     but the helper now self-guards: only increment when both endpoints
     are scheduled. Same change applied to plan §Task 3 topoSort body.

Subject: [PATCH 129/388] fix(tracker-resources): PR5 violated bars paint red

A bar with isViolated=true but isCritical=false was previously only
getting the dashed stroke-dasharray; the stroke colour stayed at the
data-conflict signal and should be visually as loud as critical bars.

Treat violated like critical for stroke colour and width; keep the
4 2 dasharray as the disambiguator between the two states. The
violated CSS class is now also applied for downstream rule hooks.

Subject: [PATCH 130/388] fix(tracker-resources): connector dot above arrows +
 target drop indicator
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two related UX bugs reported by user:

1. Blue connector dot occluded by dependency arrow
   - GanttDependencyArrow renders an invisible 12 px stroke as a click-
     target (line 77). When that target overlapped the 10 px connector
     hit-circle, SVG paint order let the arrow win every click and the
     dot became un-grabbable.
   - Fix: extract the connector dot from GanttBar (rendered inside the
     bars layer, before the dep-layer) into a new sibling overlay group
     in GanttCanvas, rendered AFTER GanttDependencyLayer. Paint order
     now puts the dot above all arrows without changing the dep-arrow
     click-target geometry.

2. No drop-target indicator on the receiving bar during connector-drag
   - During connector-drawing the user only saw the bezier preview
     dangling from the source; the target bar gave no visual cue.
   - Fix: while activeDrag is connector-drawing OR connector-target-
     hover, the overlay renders a small grey 'drop here' circle at the
     FS target anchor (left edge) of every editable bar that isn't the
     source. When the cursor is over that bar (connector-target-hover),
     the circle grows to 6 px and switches to the same indigo as the
     source dot — a strong 'release now' affordance.

Both behaviours land in the same overlay <g> for paint-order coherence.

Subject: [PATCH 131/388] feat(tracker): readable Dependencies panel +
 IssueRelation activity presenter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

User feedback (2026-05-13): the Dependencies panel was packing kind +
direction + identifier + truncated title into one tight cell, hard to
scan and not editable without going back to the Gantt. Activity log
entries for new dependencies just said 'New related to: Dependency'
which gave no clue what was added or removed.

Two changes:

1. IssueDependenciesPanel rewrite (still in the issue side panel):
   - Split into Predecessors (incoming) + Successors (outgoing) groups
     with small section labels
   - Coloured kind badge (FS=indigo / SS=violet / FF=amber / SF=red)
     matching the same palette used in cascade-popup legend
   - Separate lag pill (skipped when lag=0)
   - Full title visible (with overflow-ellipsis + native title tooltip
     for the rare wide-screen cases)
   - '+' button in the section header opens ObjectSearchPopup to pick
     a target issue, writes a default FS lag=0 IssueRelation. User can
     click the row immediately to refine kind/lag via DependencyEditor.

2. IssueRelationPresenter:
   - Tiny single-line component '<kind> [<lag>] → <ident> <title>'
   - Registered as the ObjectPresenter mixin for tracker.class.
     IssueRelation in models/tracker/src/presenters.ts
   - Activity entries now render as 'New related to: FS +2d → OSTRO-29
     Office/social container' instead of the generic 'Dependency'.
     Same applies to remove-activity entries — the user can see
     exactly which dependency disappeared.

Adds two new i18n keys (GanttSuccessors) + DE translations.

Subject: [PATCH 132/388] refactor(tracker-resources): collapse connector-drag
 to a single event path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

the 30 ms lastDownAt debounce was masking:

1. GanttConnectorDot template <g> + <circle.gantt-connector-dot> +
   <circle.gantt-connector-hit> all bound on:pointerdown + on:mousedown
2. GanttConnectorDot onMount addEventListener('pointerdown'/'mousedown')
   directly on the hit-circle DOM node
3. GanttView document-capture pointerdown/mousedown listener
   (handleNativeConnectorDown) scanning .closest('.gantt-connector'),
   plus a synthetic 'gantt-connector-start' CustomEvent dispatched from
   onDown and caught by handleConnectorStartEvent on document

Paths 2 and 3 were workarounds from the bezier-preview-debug era —
when Svelte events weren't firing reliably for synthetic Playwright
mousedowns. The real bug then was a reactivity issue (livePath function
indirection) which has been fixed since. Now that the connector dot is
also rendered in the canvas-overlay where Svelte event flow is well-
behaved, the workarounds are redundant.

After this commit only one mechanism remains:

  GanttConnectorDot <circle.gantt-connector-hit> on:mousedown=onDown
    → dispatch('connectorDown', { cursorX, cursorY })
    → GanttCanvas on:connectorDown forwarder
    → GanttView on:connectorDown handler
    → reduce(state, mousedown-connector) + attachWindowDragListeners()

Removed:
- GanttConnectorDot.onMount + onDestroy addEventListener pair
- GanttConnectorDot dispatch of 'gantt-connector-start' synthetic event
- GanttConnectorDot template bindings on the wrapper <g> and the
  visible <.gantt-connector-dot> (the visible dot is pointer-events:
  none anyway; the wrapper was redundant with the hit-circle binding)
- GanttView handleNativeConnectorDown function
- GanttView handleConnectorStartEvent function
- GanttView containerEl + document addEventListener for both above
- gantt-root <div> capture-phase on:pointerdown / on:mousedown attrs

The lastDownAt debounce is kept as a defensive guard against the rare
browser-double-fire of mousedown on the same hit-circle; it's now a
no-op in normal flow.

Subject: [PATCH 133/388] refactor(tracker-resources): drop canvas-level
 connector delegation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

introduced at the GanttCanvas level — canvasEl.addEventListener for
pointerdown + mousedown delegating to startConnectorFromIssueId via
.closest('.gantt-connector'). This violated the 'single event path'
commit message and worse, GanttConnectorDot only listens to mousedown
while this delegate listened to both, so a single physical click on
the dot would fire pointerdown via the canvas path AND mousedown via
the Svelte path with no debounce shared between them.

Removed everything redundant from GanttCanvas.svelte:
- canvasEl let + bind:this={canvasEl} on the <svg>
- forwardConnectorDown (was attached to the now-removed in-bar dot)
- startConnectorFromIssueId
- onCanvasConnectorDown
- onMount / onDestroy hooks that wired the listeners
- on:connectorDown={forwardConnectorDown} on the bar-render <GanttBar>
- onMount + onDestroy imports (no remaining uses in this file)

Surviving path is exactly what the v85 commit message described:

  GanttConnectorDot <circle.gantt-connector-hit> on:mousedown=onDown
    → dispatch('connectorDown', { cursorX, cursorY })  // Svelte
    → overlay <GanttConnectorDot on:connectorDown={…}> inline handler
      in GanttCanvas converts to { source, originPx } and dispatches
    → GanttView on:connectorDown={handleConnectorDown}
    → reduce(state, mousedown-connector) + attachWindowDragListeners

Net diff: -45 lines, including imports.

User-reported issues with the issue-editor Dependencies panel:

1. 'Search for Task' list empty after first + click, then Relations row
   disappears entirely.
   Root cause: ObjectSearchPopup's ignore prop becomes $nin: <Ref[]> in
   the DocumentQuery — the CockroachDB adapter crashes on JSONB $nin
   with 'unsupported comparison operator: _id != ALL …'. The thrown
   query also tears down the live-query for the panel, so the panel
   itself disappears once the error surfaces.
   Fix: drop the ignore param entirely. Filter self/duplicate/cross-
   project in the result callback instead.

2. + click opens the popup without focusing the Issues tab.
   Fix: pass allowCategory: [tracker.completion.IssueCategory] so only
   the Issues tab is shown — eliminates the wrong-default-tab problem
   and removes irrelevant tabs (Person, Project, Document) for a
   dependency picker.

3. Picker shows cross-project issues. Phase-1 only supports intra-
   project dependencies.
   Fix: when the result space != current issue's space, reject with a
   notification banner instead of writing the relation. Cycle check
   (PR4a wouldCreateCycle) also applied to the callback path so the
   issue-editor flow has the same protections as the Gantt connector
   drag.

4. No way to remove a dependency from the panel.
   Fix: per-row hover-only '×' button that calls ops.removeDoc on the
   IssueRelation. Same permission gate as the editor: source-side
   editable user only.

5. Identifier displayed prominently, title secondary.
   Fix: swap — title primary, identifier moved into the native title
   tooltip. Same swap applied to IssueRelationPresenter so activity
   entries read 'New related to: FS +2d → Storage silo construction'
   (instead of '… → OSTRO-29 Storage silo'). The OSTRO-29 identifier
   stays accessible via hover tooltip on the activity row.

Subject: [PATCH 135/388] fix(tracker): scope dependency picker to current
 project
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace ObjectSearchPopup with ObjectPopup using docQuery:
{ space: issue.space } so cross-project issues no longer appear
in the dependency picker — matches the SetParent picker
convention (Phase-1 deps are intra-project only).

ignoreObjects excludes self and existing successors before the
list is rendered; cycle detection stays in the callback because
it needs the full relation graph.

Bare ObjectPopup with no slot="item" loads docs but renders
nothing — its default item fragment is gated on
{#if $$slots.item}. v88 invoked ObjectPopup directly via
showPopup() which can't pass slots, so the dependency picker
showed an empty list.

Add SelectDependencyIssuePopup wrapper that mirrors
SetParentIssueActionPopup's structure: ObjectPopup with the
required slot="item" (status icon + identifier + title),
plus docQuery: { space: issue.space } and ignoreObjects to
keep the picker project-scoped and excluding self/existing
successors.

Subject: [PATCH 137/388] feat(tracker): label LinkExistingSubIssue button + DE
 translation

The 'Link existing sub-issue' affordance already existed as an
icon-only ghost Button next to QueryIssuesList's prominent
'+ Add sub-issue'. It was undiscoverable: only a hover-tooltip
revealed what it did.

Add an inline label so the action reads visibly next to its
icon, and provide a German translation for the i18n key.

Subject: [PATCH 138/388] feat(tracker): unified hierarchy add chooser +
 resizable pickers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

UX: replace direct + buttons for parent/sub-issue hierarchy with a
two-option chooser popup (HierarchyAddPopup) — both directions now
visibly offer 'Create new' AND 'Link existing' regardless of whether
the issue already has children.

Plumbing:
 - HierarchyAddPopup (new) — chooser with 'parent' | 'sub' direction
 - CreateIssue dispatches close-with-id on success so the new
   'Create new parent' flow can write attachedTo on the calling issue
 - QueryIssuesList accepts customAddAction prop; slot=buttons ungated
   so any caller-supplied accessory buttons stay visible without
   sub-issues
 - SubIssues passes customAddAction that opens the chooser; legacy
   icon-only LinkSubIssue button removed (chooser supersedes it)
 - EditIssue Set-parent button opens chooser; routes 'create' to
   CreateIssue and on close re-ranks current issue under new parent

Resizable pickers:
 - new ObjectPopup/DocPopup width: 'resizable' value
 - popups.scss .width-resizable: 48rem × 36rem default, resize: both,
   min 28rem×16rem, max 96vw×96vh
 - SelectDependencyIssuePopup, SetParentIssueActionPopup,
   LinkSubIssueActionPopup default to 'resizable' so the existing
   call sites pick up the larger draggable pickers automatically

i18n: AddParentIssue, AddSubIssue, CreateNewParentIssue,
CreateNewSubIssue, LinkExistingParentIssue in en + de.

Subject: [PATCH 139/388] =?UTF-8?q?feat(tracker):=20dependency=20direction?=
 =?UTF-8?q?=20chooser=20=E2=80=94=20predecessor=20+=20successor?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Dependencies-panel "+" button silently wrote outgoing (successor)
relations only. Add a two-option chooser mirroring the hierarchy add
chooser pattern: "Add predecessor" / "Add successor" with directional
hint tooltips.

Predecessor flow attaches the new IssueRelation to the picked issue
(picked is the source), permission-gates on the picked issue, and the
picker's ignore set uses incoming.attachedTo refs rather than
outgoing.target refs. extraIgnore prop added to
SelectDependencyIssuePopup so callers don't have to wrap raw ids in
fake IssueRelation shapes.

i18n: AddDependency, AddPredecessor, AddSuccessor + direction hints
(en + de).

Subject: [PATCH 140/388] fix(tracker): cycle check uses project-wide relations
 + neutralize review comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The dependency-add cycle check in the issue-editor panel used only
incoming + outgoing slices of the current issue:

  wouldCreateCycle(sourceId, targetId, [...incoming, ...outgoing])

That catches direct A→A and direct duplicates but misses transitive
cycles. Example: with C→B and B→A already in place, adding A→C from
A's panel passes the check because C→B is not in A's local slice —
the DFS never sees the back-edge B→A→C from the C side, so the new
edge silently closes the loop. The Gantt view already does a
project-wide check; the issue panel must match.

Add a third live-query bound to { space: issue.space } that loads all
relations in the project, and pass the full list to wouldCreateCycle
on add. The visible Predecessors/Successors lists keep using the
existing incoming/outgoing slices.

gantt + dependency code. The substance of each note is preserved but
rephrased so the comments document the technical reason, not the
review thread that surfaced it.

Subject: [PATCH 143/388] fix(tracker-resources): resolve eslint errors in
 gantt dependency/cascade tier

Apply the reviewer-approved fix patterns to the pre-existing eslint errors
surfaced by the CI formatting job in the PR3b feature code:
- no-confusing-void-expression: block-body arrows for void event handlers
  (GanttCanvas/GanttSidebar/ConfirmCascadePopup/GanttHelpPopup dblclick/click/
  cleanup handlers).
- no-misused-promises: single stable void-wrapper (onWindowPointerUp) shared by
  attach/detach so the listener reference stays paired.
- prefer-optional-chain: nested {#if} guards preserving TS narrowing
  (GanttCanvas connector overlay, GanttDependencyLayer) and loose == null form.
- no-invalid-void-type: dispatcher payload void -> undefined (matches the
  codebase convention).
- strict-boolean-expressions: explicit zero / nullish handling in
  dependency-router and exporter.
- test files: drop non-null assertions in favour of optional chaining, remove
  unused imports/vars, rename snake_case locals to camelCase.

From 022618b1adc7cdc73ee094d96edda480f927193d Mon Sep 17 00:00:00 2001
From: Michael Uray <michaeluray@users.noreply.github.com>
Date: Fri, 3 Jul 2026 08:24:56 +0000
Subject: [PATCH 145/388] fix(tracker-resources): repair GanttView imports and
 drop orphaned mouseup wrapper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The cascade merge + eslint import consolidation left three type errors
svelte-check flags in the PR3b GanttView:
- the './lib/types' import got merged into an `import type { ... }` with
  redundant inner `type` modifiers (invalid syntax) — flatten to plain names;
- `getEventPositionElement` was dropped from the @hcengineering/ui import —
  restore it (used by openGanttMenu);
- an onWindowMouseUp wrapper carried over from the PR3a edit tier referenced
  handleCanvasMouseUp, which PR3b renamed to handleCanvasPointerUp (wrapped as
  onWindowPointerUp) — remove the now-dead, dangling wrapper.

 HierarchyAddPopup chooser
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Der Add-Sub-Issue-Button oeffnet seit bc2414a569 (unified hierarchy add
chooser) nicht mehr direkt das CreateIssue-Formular, sondern zuerst den
HierarchyAddPopup mit den Optionen 'Create new sub-issue' /
'Link existing as sub-issue'. Die Playwright-page-objects clicken den
Zwischenschritt jetzt mit, bevor das Formular gefuellt wird:

 - IssuesPage.clickOnSubIssues        (subissues.spec 'create sub-issue')
 - IssuesDetailsPage.clickButtonAddSubIssue
   (subissues.spec 'Edit a sub-issue' / 'Delete a sub-issue')

Keine Assertion abgeschwaecht, kein Timeout erhoeht — nur der neue
UI-Pfad wird durchlaufen (analog zur milestone-page-object-Anpassung in

Subject: [PATCH 147/388] test(tracker): make buttonEstimation locator
 sibling-based, not positional
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Gantt schema PR (ControlPanel) adds several unconditional rows between
Assignee and Estimation in the issue side panel (Start date, Due date,
Deadline, Scheduling mode). The prior positional locator
(//span[text()="Estimation"]/../div/button)[N] had to be re-indexed each
time a row was added and had drifted to [5], which no longer resolves to the
Estimation editor button — so editIssue's estimation step could never open
the EditBoxPopup and 'div.selectPopup input' never appeared, failing
issues.spec:49 'Edit an issue' and subissues.spec:52 'Edit a sub-issue'.

Switch buttonEstimation to the same following-sibling path already used by
textEstimation, which targets the Estimation label's own editor button
regardless of how many rows precede it.

Subject: [PATCH 148/388] chore(tracker): reconcile i18n + Gantt sources after
 develop rebase

Restore the ru.json dependency/cascade i18n keys and the final Gantt
component sources that were carried into this branch via a merge commit.
Linearizing the branch onto the new develop dropped that merge, so this
commit re-materializes the exact intended tip content (develop does not
touch these files).

Subject: [PATCH 149/388] fix(tracker-resources): align relationSatisfied with
 new anchor semantics

The Alt-bypass violation count was still computing FS with the old
'predDue + lag' (no +1-day) formula. Aligning it with the new fsAnchor
helpers keeps Alt-bypass agreeing with cascade decisions and the CP
overlay in both legacy and working-days modes.

Subject: [PATCH 150/388] feat(tracker-resources): wire project
 workingDaysConfig into Gantt scheduler/CP

GanttView now subscribes to the current Project document and reads its
optional workingDaysConfig. The config is forwarded to:
- computeCriticalPath via the new third argument (cfg)
- simulateCascade via options.workingDays

Reactive: a project-config change retriggers the debounced CP recompute
exactly as issue/relation mutations already do. Spaces without a Project
(or with no config set) keep legacy calendar-day behaviour.

Subject: [PATCH 151/388] fix(tracker-resources)!: respect working-days in
 cascade scheduler, fix FS +1d off-by-one
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

simulateCascade now accepts an optional WorkingDaysConfig via
`options.workingDays`. Forward and backward FS/SS/FF/SF anchor math
routes through the new working-days helpers, which fall back to legacy
calendar-day arithmetic when no config is given.

The legacy branch also implements the +1-day FS rule that critical-path
already obeys. Previously scheduler.ts computed FS successor anchor as
`predDue + lag * DAY_MS`, while critical-path.ts used `predDue + DAY_MS
+ lag * DAY_MS`. This silent disagreement meant cascade and CPM could
disagree about whether a successor was satisfying the FS constraint by
exactly one day. The spec (§Datums-Semantik) makes the +1-day rule
verbindlich; this commit aligns scheduler.ts with that convention.

BREAKING CHANGE: three pre-existing test expectations encode the bug
and were recalibrated:
- Test 5 (pull-predecessor): A.newDue = May 1 (was May 2), newStart =
  Apr 27 (was Apr 28).
- Test 6 (FS lag=2): B.newStart = May 8 (was May 7).
- Test 7 (FS lag=-1): B.newStart = May 12 (was May 11).

New tests cover the working-days mode (Mo-Fr, holidays, pull-predecessor
across a weekend) plus the legacy +1-day FS rule.

Subject: [PATCH 152/388] feat(tracker-resources): paint non-working-day tint
 in Gantt canvas
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a new background layer in GanttCanvas that fills every weekend or
holiday day with a low-alpha theme-divider colour. The layer renders
between the SVG root and the gridlines so it sits under all bars and
overlays — pointer-events are disabled.

- viewport.ts: new pure helper nonWorkingDaysInRange(from, to, cfg, max)
  returning UTC-midnight timestamps of non-working days in the viewport.
  Returns [] in legacy mode so the canvas pays zero cost when the project
  has no working-days config.
- GanttCanvas.svelte: new workingDaysConfig prop + reactive
  nonWorkingDays array, threaded into a dedicated <g class='non-working-days'>
  group.
- GanttView.svelte: forwards the project's cfg to the canvas.
- 5 new viewport tests covering legacy mode, weekend listing, the
  maxDays cap, inverted ranges, and explicit holidays.

Subject: [PATCH 153/388] feat(models/tracker): persist
 Project.workingDaysConfig + EN/DE strings

- TProject gains an optional workingDaysConfig property stored as a JSON
  Record (TypeRecord). Optional + additive: every existing Project keeps
  workingDaysConfig=undefined, preserving legacy calendar-day behaviour.
- Migration registers the new state 'gantt-add-working-days-config' as a
  no-op upgrade entry so the tracker schema-version tracker advances.
- 14 new IntlString keys (WorkingDaysConfig, WorkingDaysTitle, ..., per-
  weekday short labels Mon..Sun) registered in plugins/tracker/src/index.ts.
- EN + DE translations added in plugins/tracker-assets/lang/{en,de}.json
  for all 14 new keys.

This commit only persists the type and surfaces the labels; the
project-settings UI to edit the config is intentionally deferred to a
follow-up so this PR stays focused on scheduler correctness.

Subject: [PATCH 154/388] feat(tracker-resources): respect working-days in
 critical-path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

computeCriticalPath now accepts an optional WorkingDaysConfig and routes
forward/backward anchor math through the shared working-days helpers.
Slack stays in milliseconds (LS - ES) to keep the result shape stable
for existing UI consumers; conversion to a working-day count for display
purposes is the caller's responsibility.

The legacy +1-day FS rule that critical-path already used now lives in
fsAnchor itself — both critical-path and scheduler share that source of
truth, eliminating the prior off-by-one drift between them.

All pre-existing CP tests remain green; new tests cover:
- FS chain across a weekend (Fri → next Mon is tight, no slack)
- FS lag=2 violation when succ is pinned earlier than required wd
- Holiday in the dependency gap forces a violation
- Legacy-mode regression check

Subject: [PATCH 155/388] feat(tracker): add WorkingDaysConfig type + scheduler
 working-days helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Introduces the data shape and pure helper functions for Phase 2 of the
Gantt UX polish — a per-project working-days calendar.

- WorkingDaysConfig interface on tracker.Project (optional). Weekday mask
  uses bit 0=Mon..bit 6=Sun; holidays as UTC-midnight timestamps. Absence
  of the property means 'every day is a working day' (legacy mode).
- plugins/tracker-resources/.../lib/working-days.ts: pure helpers
  isWorkingDay, nextWorkingDay, addWorkingDays, workingDaysBetween, plus
  the four anchor functions fs/ss/ff/sf and their reverse counterparts.
  All accept cfg | undefined so the same call-site serves legacy and
  working-days mode.
- 44 Jest cases covering weekday mask, holidays, midnight rounding,
  cross-weekend arithmetic, negative spans, anchor semantics in both
  legacy (with the +1d FS fix) and Mo-Fr modes.

Helpers are not yet wired into scheduler.ts or critical-path.ts; those
follow in the next two commits to keep the diff readable.

From 85bfefb4f30f6e71ee6b37ecb66444912f928ceb Mon Sep 17 00:00:00 2001
From: Michael Uray <michaeluray@users.noreply.github.com>
Date: Fri, 15 May 2026 13:58:48 +0000
Subject: [PATCH 156/388] fix(tracker-resources): re-stamp virtualized sidebar
 row y from current index
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GanttView's sortedRows post-sort reordering kept each row's buildLayout()
y, which then drove the absolute position when the sidebar virtualizes.
That made the sorted sidebar visually appear in pre-sort order. Now the
sidebar derives vy = i × rowHeight from the current iteration index so
the rendered order matches the iteration order regardless of any
upstream sort or filter.

Subject: [PATCH 157/388] test(tracker-resources): cover groupRowsToLayoutRows
 adapter

Three additional assertions covering the LayoutRow shape produced for
group-header rows (collapsible=true, issue/milestone=null, groupKey/
Count/Label populated), the issue-row carry-through of groupKey for the
canvas tint, and the preservation of y / height from the source group
rows.

+
+  Per-issue toggle between cascade-driven scheduling (`'auto'`, the default)

+  explicit click back to Auto — moving a predecessor never re-arms cascade.
+
+  Mounted in `ControlPanel.svelte` next to Start- and Due-Date, mirroring the
+  Priority/Status editor pattern (small Button with link kind + leading icon).
+
+  The Manual decision propagates through `gantt/lib/scheduler.ts` (Step 4
+  BFS filter) and `GanttBar.svelte` (pin glyph), both wired in the same
+  commit-stack as this editor.

Subject: [PATCH 159/388] test(tracker-resources): tighten sidebar-sort fixture
 typing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The mkIssue test fixture was using a Partial<Issue> spread + a literal
'string' for _id, which violates the branded Ref<Issue> shape under
strict svelte-check. Replace with an explicit IssueOverrides interface
that casts _id once and feeds the rest of the Issue fields through
fixed defaults — keeps the test surface readable while making
svelte-check happy.

Subject: [PATCH 160/388] feat(tracker-resources): add GanttSidebarHeaderCell +
 GanttSidebarColumn components

GanttSidebarHeaderCell handles the sortable header label and the column
resize handle on the right edge. Resize uses window-level mousemove/up
listeners with clean teardown on mouseup or component destroy.

GanttSidebarColumn dispatches per-column-key cell rendering: identifier
(IssuePresenter), title (clickable openIssue), status (StatusBadge),
priority/estimation/dates as read-only text, predecessors/slack reusing
the existing helpers. Inline-edit popups are reserved for Phase 3a.v2
when the undo-manager (Phase 3c) is in place.

EN+DE i18n added for the 16 column header labels, the extended-mode
toggle and the sort-breaks-hierarchy warning tooltip.

Subject: [PATCH 162/388] feat(tracker-resources): add sidebar-columns pure
 helpers for Phase 3a

Introduce SidebarColumnKey union, DEFAULT_COLUMNS, DEFAULT_WIDTHS map,
MIN/MAX_WIDTH clamps and a defensive parseColumns coercer that always
yields at least one valid column. 16 unit tests cover the legal and
malformed input paths.

Subject: [PATCH 163/388] feat(tracker-resources): wire Phase 3b filter-bar +
 group-by swimlanes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GanttView.svelte:
- Read ganttGroupBy from viewOptions (safe fallback 'none')
- In-memory ganttFilter + collapsedGroups (per-mode reset on group switch)
- filteredIssues feeds buildLayout (legacy) OR buildGroupedRows
- onToggle routes 'group:*' ids to collapsedGroups
- sortedRows short-circuits when groupBy active (sort applied within lane)
- Toolbar-right gains: Filter button with badge + popup (priority chips),
  Group-By dropdown with overrides-hierarchy tooltip
- Ctrl+F/Cmd+F shortcut toggles the filter popup (was reserved in Phase 1)

GanttSidebar.svelte:
- Renders 'group-header' rows in both legacy and extended-grid layouts
  with chevron, label, count; spans full grid width

GanttCanvas.svelte:
- Paints lane-tint band behind 'group-header' rows (.group-header-bg)

lib/types.ts:
- LayoutRow.kind union extended with 'group-header'
- Optional groupKey/groupLabel/groupCount fields

lib/build-rows.ts:
- groupRowsToLayoutRows adapter so existing Sidebar/Canvas iterate the
  same LayoutRow[] for both legacy and grouped modes

Strings:
- 22 new EN+DE keys for GroupBy / Filter / sentinel labels

256 → 289 Jest tests (green); svelte-check passes.

Subject: [PATCH 164/388] feat(tracker-resources): add group-by + filter pure
 helpers for Phase 3b
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three pure modules and their Jest suites:
- group-by: resolveGroupKey/sortGroupKeys/getGroupLabel + sentinels
  (__unassigned__, __no_component__, __no_milestone__, __no_label__,
  __unknown__). 17 tests.
- build-rows: buildGroupedRows produces the flat row stream with
  discriminated 'group-header' | 'issue' rows and pre-computed y
  positions. Supports withinGroupCompare for the Phase-3a sort hook.
  7 tests.
- filter-predicate: applyFilter / countActiveFilters with AND-across-keys
  and OR-within-key semantics; unknown keys ignored for forward compat.
  9 tests.

256 → 289 Jest tests (all green).

+ * can write the same `{ status: [] }` shape it would use for a populated

+ * Tier-2 Item 5 — cascadeToken plumbing.
+ *
+ * Every cascade-related commit in the Gantt (single-drag, parent-drag,
+ * bypass and the soon-to-arrive bulk-drag from Tier-2 Item 6) attaches
+ * a fresh token to the `client.apply(undefined, scope)` call. The token
+ * is the `scope` string, so downstream consumers can correlate every
+ * sub-Tx of the same cascade by scope-string equality:
+ *
+ *   • Tier-2 Item 6 (Bulk-Drag) — all bulk-moved primaries plus their
+ *     cascade fanout share one token, so the dependency-graph layer
+ *     can build a single visual undo entry per bulk operation instead
+ *     of N entries (which would over-count in the undo stack).
+ *
+ *   • Tier-4 Item 14 (Dependency-Shift-Notification) — the server-side
+ *     trigger reads `TxApplyIf.scope` and aggregates all Txes sharing
+ *     a `gantt-cascade-*:<id>` prefix into one notification per user.
+ *     Without the token a 20-issue cascade fires 20 generic update
+ *     notifications (or 20 dependency-shift ones), which is exactly
+ *     the spam the spec §3 calls out.
+ *
+ * The token is intentionally a *string* and not a Tx-Mixin, because:
+ *   1. No schema change → no migration cost.
+ *   2. `TxApplyIf.scope` already round-trips through the server (it
+ *      drives the optimistic-concurrency match-set), so it is visible
+ *      to triggers without extra plumbing.
+ *   3. Plays nicely with `client.apply()` overloads that already accept
+ *      a scope string everywhere in this codebase.
+ *
+ * The suffix is `Date.now()` plus a monotonic counter — collision-free
+ * within one client process, unique enough across processes for the
+ * notification batching window (~minutes). If we ever need cross-server
+ * uniqueness, swap the suffix for a v4 UUID without touching the call
+ * sites; the prefix contract stays.
+ */
+
+let counter = 0
+
+/**
+ * Returns a fresh cascade-token usable as the `scope` argument of
+ * `client.apply(undefined, scope)`. The default prefix is `gantt-cascade`;
+ * specialized call sites pass their own scope (`gantt-cascade-commit`,
+ * `gantt-cascade-bypass`, `gantt-no-cascade`, `gantt-bulk-drag`, …) so
+ * that the leading segment of the scope still classifies the call site
+ * for human-readable tx-logs, while the trailing `:<id>` segment
+ * identifies the cascade instance.

Subject: [PATCH 171/388] feat(tracker-resources+models): wire Phase 3a
 extended sidebar grid
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GanttSidebar grows an opt-in extendedColumns mode: when on, it renders a
sortable header row + per-column cells via GanttSidebarColumn and emits
sortChange / widthChange events. When off (default), the legacy compact
4-cell layout is preserved bit-for-bit, so existing users see no surface
change on upgrade.

GanttView holds the sidebar columns / widths / sort state in-memory,
applies the comparator to the row feed when sort is active (breaks
hierarchy by design — spec warns via tooltip), and forwards events from
the new header cells back into the cycleSort reducer.

models/tracker/viewlets.ts registers the ganttSidebarColumnsExtended
toggle in the Customize-View drawer alongside the existing PR4a/PR5
display toggles. Default OFF.

Subject: [PATCH 173/388] feat(tracker-resources): style gantt tree breadcrumbs
 and depth guide-lines

- Add .tree-breadcrumb class (opacity 0.6 + italic) to parent-of-match rows
  in both the left grid pane and the right sidebar pane (right-pane carries
  a tooltip on the title-label span).
- Add .tree-indented class on rows with depth > 0; render a dashed vertical
  guide-line 10px from the row's left edge so siblings share a visual rail.
- Bump indent step from 16px to 20px per Tier-4 spec.
- Wrap the issue-title text in an inner .cell-title-label span so the
  breadcrumb use:tooltip directive does not break Svelte's TS inference on
  the link's sibling event handlers.

Subject: [PATCH 177/388] feat(tracker-resources): clip dep-arrows + add
 off-viewport row indicators
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Tier-3 Item 5 — when a dependency arrow's source or target bar lives
outside the visible y-band, the arrow is now clipped to the viewport edge
and rendered with a triangle indicator (▲ for top-off-screen, ▼ for
bottom-off-screen) in the arrow's stroke color. Clicking the indicator
smooth-scrolls to the off-screen row's y so the user can follow the
dependency chain. Both endpoints off-screen on opposite sides still renders
the bezier (it crosses the viewport vertically); both off the same side
culls the arrow entirely.

Lag pill is suppressed for clipped arrows — the pill at the viewport edge
is visually ambiguous about which side the lag applies to.

Subject: [PATCH 180/388] feat(tracker): i18n + IntlString refs for Phase 1
 (Visual Polish)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the EN/DE strings and IntlString placeholders that all four
Phase 1 features (Bar-Labels, Deadline-Marker, Keyboard-Shortcuts,
Quick-Info-Popover) depend on. No behaviour change yet — only
strings + types so subsequent commits can reference them.

Soft deadline independent of dueDate. Undefined for existing
issues; workspace upgrade adds the property schema (additive)
without any data migration. Used by the Gantt deadline-marker
in subsequent commits.

Subject: [PATCH 187/388] feat(tracker-resources): keyboard shortcuts T/D/W/M/Q

Adds direct zoom-level keys (D=day, W=week, M=month, Q=quarter)
and T=jump-to-today, mirroring the toolbar buttons. Only fires on
bare keys (no Ctrl/Cmd/Alt) so it doesn't hijack browser shortcuts
like Ctrl+D=bookmark. Uses setZoom() so the scroll-reset and
viewport-sync match the buttons exactly.

Cmd+Z, Cmd+Shift+Z, Ctrl+F, Ctrl+G are intentionally NOT wired in
this phase -- they belong to Phases 3b/3c (Filter/Group-By and
Undo/Redo) and will be added when those features exist.

Subject: [PATCH 188/388] fix(tracker-resources): center Gantt nav, reorder
 PNG/PDF/Fullscreen, keep toolbar in fullscreen

- IssuesView: wrap GanttToolbarControls in .gantt-row2-center so the
  date-nav + zoom group stays centered between ModeSelector (left) and
  PNG/PDF/Fullscreen (right) on row 2 regardless of side-element widths.
- GanttExtraActions: final button order PNG, PDF, Fullscreen (Expand icon).
- GanttView.toggleFullscreen: walk up the DOM from .gantt-root to find
  the nearest popupPanel-body/.app-content/.antiPanel-application
  ancestor so that fullscreen wraps the second header row too. The user
  needs Today/Day/Week/Month/Quarter to remain reachable without exiting.

Subject: [PATCH 189/388] feat(importer): support Gantt scheduling fields in
 HulyFormatImporter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends the importer's YAML schema with the fields needed to express
Gantt-rich projects (Components, Milestones, dates, deadlines,
dependencies). Required so demo workspaces — most importantly the
upstream 'Game Design (Example)' that ships in hcengineering/init —
can showcase the new tracker features that landed in Phase 1 + the
PR1–PR7 stack.

New HulyIssueHeader fields:
- startDate, dueDate  — ISO YYYY-MM-DD or ${today+Nd} relative
- deadline           — Phase 1.B soft deadline (renders flag marker)
- component, milestone — references by LABEL into the project's
  components/milestones arrays
- predecessors       — array of identifiers / titles for FS deps

New HulyProjectSettings fields:
- components[]       — { label, description }
- milestones[]       — { label, description, targetDate, startDate }

Relative-date placeholders (${today}, ${today+5d}, ${today-3d},
${today+2w}, ${today+1mo}) keep demo workspaces fresh — every install
gets dates relative to install day, so the Gantt looks 'current' a
year later too.

Builder logic (importer.ts):
- createDoc one Component / Milestone per project entry, indexed by
  label for issue look-up.
- importProject collects an issueIdByTitle + issueIdByIdentifier
  map as it walks the tree, then resolves predecessor refs in a
  second pass and emits one tracker.class.IssueRelation per pair.
- createIssueWithSchedule is a thin wrapper around createIssue that
  patches the freshly-created Issue with startDate/dueDate/deadline/
  component/milestone if the front-matter declared them — keeps the
  base createIssue signature unchanged for Linear/Notion/Trello.

Tests:
- svelte-check + Jest 173/173: all green
- Build to @hcengineering/importer: clean

Note: this is the IMPORTER side only. The demo content in
hcengineering/init still needs to be enriched with the new fields —
that lives in a separate repo and is the next slice of this work.

Subject: [PATCH 190/388] feat(tracker): expose Issue.deadline on the public
 interface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The deadline field was added to the model in commit e53e49186 but only
to TIssue (models/tracker/src/types.ts). The public Issue interface in
plugins/tracker/src/index.ts never declared it, so every consumer in
tracker-resources used a typed-intersection cast pattern:

  (issue as Issue & { deadline?: number | null }).deadline

as an interface inconsistency to bury before the upstream PR.

This commit:
- Adds 'deadline?: Timestamp | null' to the Issue interface, mirroring
  the model declaration's optionality semantics.
- Removes the casts in deadline-marker.ts (hasDeadline, isOverdue),
  GanttCanvas.svelte (getDeadline helper), and DeadlineEditor.svelte
  (drops the local IssueWithDeadline type alias and the Partial<Issue>
  cast on the updateCollection payload).

No behaviour change — every consumer was already correctly reading
issue.deadline through the cast.

Subject: [PATCH 192/388] feat(model-tracker): migrate IssueGantt viewOptions
 for existing workspaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phase 1 (Visual Polish) added four new ViewOptions in viewlets.ts
(ganttBarLabelLeft/Inside/Right + ganttQuickInfoOnClick). Because
builder.createDoc is idempotent, existing workspaces' IssueGantt
viewlet doc keeps its old viewOptions array on upgrade-workspace —
the new entries never make it to the Customize-View popover for
users who created their workspace on an older gantt-vN.

Add an 'add-gantt-phase1-view-options' upgrade state that:
  - finds the IssueGantt viewlet doc by _id,
  - merges-by-key any missing entries from ganttViewOptions().other
    into the doc's viewOptions.other (preserves user's groupBy,
    orderBy, and any pre-existing Phase-0 entries verbatim),
  - is fully idempotent (re-runs see missing=[] and short-circuit).

Mirrors the pattern in models/card/src/migration.ts (line 677:
addShowAllVersionsViewOption) — same TxOperations.update path on
view.class.Viewlet, same merge-by-key shape, same registration
under MigrateOperation.upgrade. An earlier attempt at this migration
(see smoke-report dated 2026-05-14) used a wholesale tx.update with
viewOptions: ganttViewOptions() which the platform rejected with
BadRequest; the Card-pattern merge avoids the BadRequest because
groupBy and orderBy are preserved by spread instead of replaced.

Subject: [PATCH 193/388] fix(importer): use bare 'today+Nd' syntax for
 relative-date placeholders

The global UnifiedFormatParser eagerly resolves every ${...} token in
YAML before the HulyFormatImporter's date parser sees it and throws
'Variable not found' if the token isn't a registered script-level
variable. That made relative-date placeholders unusable in the demo
content (Game Design Example).

Switch to bare 'today', 'today+5d', 'today-3d', 'today+2w', 'today+1mo'
(no curly braces) so the global parser ignores them and our own
parseIsoDate handles them.

Demo-content side (hcengineering/init) needs a matching find-and-replace
of ${today...} -> today... across the Game Design .md/.yaml files.

Subject: [PATCH 194/388] feat(tracker-resources): consolidate Gantt toolbar +
 add fullscreen + PDF export
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phase 2 visual-polish followup to Phase 1, addressing direct UX feedback
(2026-05-14): the Gantt's dedicated toolbar row above the canvas eats
vertical space and visually duplicates the Filter/Search row that
already lives one level up in IssuesView.

Changes:

- Move date-navigation + zoom buttons from GanttView's own toolbar row
  into IssuesView's header-tools slot (right next to ViewletSetting).
  IssuesView and GanttView communicate via a new writable bus store
  (lib/gantt-toolbar-bus.ts) since they're separated by
  ViewletContentView's dynamic component mount.
- New GanttToolbarControls.svelte: pure UI component, reads state +
  handlers from the bus, renders the original navigation/zoom UI in
  a single inline row.
- New GanttExtraActions.svelte: fullscreen-toggle button + PNG export
  + PDF export, positioned right of the navigation controls.
- Fullscreen uses the standard document.fullscreenElement /
  requestFullscreen / exitFullscreen API on the gantt-root.
- PDF export goes through the browser's print pipeline: a
  .gantt-printing class is added before window.print() (auto-cleared
  ~1s later), and a new @media print stylesheet collapses the
  surrounding chrome so the saved PDF is a clean single-page chart.
  No new dependency (no jsPDF).
- GanttView keeps all the original handler functions; only the local
  toolbar DOM + CSS were removed. The bus store re-publishes the
  state via a single reactive $:.
- TOOLBAR_HEIGHT constant now 0 (was 40) so the v-scrollbar offset
  math stays simple.
- 3 new i18n strings (en + de): GanttFullscreen, GanttExportPng,
  GanttExportPdf.

Test gates:
- svelte-check: clean
- Jest: 173/173 passing (no test churn — UI-layer change)
- Build to @hcengineering/tracker-resources + @hcengineering/tracker-assets: OK

 in GanttCanvas
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A flag-triangle + dashed vertical line at each issue's deadline date.
Orange (#f59e0b) by default; pulsing red (#dc2626) when overdue
(dueDate > deadline). Rendered in the same translate group as the
issue bars, immediately before the dependency-arrow overlay, per the
Render-Layer-Order from the Phase-1 roadmap (bars → deadline-markers
→ arrows → connector-dots).

Subject: [PATCH 196/388] feat(tracker-resources): export full Gantt
 (sidebar+bars) to PNG/PDF via html2canvas+jspdf
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The previous PNG path serialised only `<svg class="gantt-canvas">`, which
contains bar geometry + arrows but none of the issue row labels — the
sidebar is a separate HTML `GanttSidebar` component. The resulting PNG
was effectively a strip of bars with no context. Replace with an
html2canvas-based capture of the entire `.gantt-root` element so the
sidebar, sticky time-axis header, and canvas are all rasterised in one
image.

The previous PDF path simply called `window.print()`, which opened the
browser's print dialog instead of producing a file. Replace with a
jsPDF-based pipeline: html2canvas at 2x DPI -> JPEG (quality 0.95) ->
landscape A4 PDF, scaled to fit while preserving aspect ratio. Output
is downloaded via `pdf.save()` like the PNG flow.

Bundle-size mitigation: both libs are pulled in with dynamic `import()`
inside `exporter.ts`, so the ~750 KB combined payload only lands in the
user's browser when the export button is actually clicked. The main
tracker-resources bundle is unchanged.

Sticky/scrolling capture trick: the Gantt uses an internal vertical
scroller plus a sticky horizontal proxy bar with `transform: translateX(...)`.
Before snapshotting we expand `.gantt-root`, `.gantt-scroller`, and
`.cell.header-cell` to their full content size, and reset the
`.hscroll-inner` translateX to zero. All mutations are tracked in a
StyleSnapshot tuple list and restored in a `finally` block so the user's
live view is unchanged even if html2canvas throws.

The deprecated SVG-only helpers (`exportGanttSvgToPng`, `exportAndDownload`)
are kept for back-compat and flagged with `@deprecated` JSDoc.

  *
- * The Gantt view renders into an `<svg class="gantt-canvas">` overlaid on
- * the sidebar (`<div class="sidebar-rows">`). Server-side rasterization
- * would require headless Chromium; we instead serialize the live SVG,
- * apply inline computed styles (so theme colours and fonts survive
- * outside the document's `<style>` cascade), draw it to an HTMLCanvas at
- * the user's chosen device-pixel-ratio scale, and `toBlob()` the result
- * as PNG. The whole pipeline is synchronous-ish (one image.onload await)
- * and runs entirely in the user's browser — no upload, no extra round-trip.
+ * The Gantt view is a CSS-grid composition of an HTML sidebar
+ * (`GanttSidebar` — issue/milestone rows as `<div>`s) and an SVG canvas
+ * (`<svg class="gantt-canvas">` — bars + arrows). Earlier versions of this
+ * module serialised only the SVG, which produced PNGs containing only the
+ * bar geometry without any of the row labels — effectively useless.
+ *
+ * The new pipeline rasterises the entire `.gantt-root` element (sidebar +
+ * sticky header + canvas) via the `html2canvas` library, then either
+ * `toBlob`s the result as PNG or feeds it into `jsPDF` for a proper PDF
+ * download. Both libs are well-maintained MIT/BSD-licensed pure-browser

+ * unaffected; the export chunk is ~750 KB combined (~300 KB gzipped).
+ *
+ * Capture trick for sticky / scrolling layouts: html2canvas captures the
+ * element as currently sized. Because the Gantt uses an internal vertical
+ * scroller (`.gantt-scroller`) and a sticky horizontal proxy bar
+ * (`.hscroll-inner` with `transform: translateX(...)`), we must
+ * temporarily expand the scroller to its full content height and reset
+ * the horizontal transforms before the snapshot, then restore everything
+ * in a `finally` block so the user's view is unchanged even if rendering
+ * throws.
  *
  * Limitations:
- *   - SVG `<foreignObject>` content (rare in Gantt) is rasterised by the
- *     browser using its own font fallbacks; results may differ slightly
- *     from the on-screen rendering.
- *   - Custom CSS that targets pseudo-elements (`::before`, `::after`) is
- *     not serialized — Huly's Gantt does not use them.
+ *   - Custom CSS that html2canvas does not understand (some `mask-image`,
+ *     advanced `filter` chains, `position: sticky` inside transformed
+ *     ancestors) may render slightly differently from the live view.
+ *   - Web fonts must be loaded before export — Huly's fonts are loaded
+ *     at app startup so this is fine in practice.
+ *   - Very tall Gantts may hit the browser's max-canvas-pixel limit
+ *     (Chrome: 32 767 × 32 767, Safari: 4096 × 4096). For PDFs the
+ *     output is scaled to fit A4 landscape so this is rarely a problem.

Subject: [PATCH 197/388] feat(tracker-resources): wire QuickInfoPopup to
 single-click bar (opt-in)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When ganttQuickInfoOnClick is true, single-click on an issue bar opens
the lightweight Quick-Info popup AFTER the existing selection + focus
update. Default false = no popup (legacy select-only, double-click still
opens the full editor as before via GanttCanvas's <g class=bar-wrap>
on:dblclick handler). The popup's 'Open full editor' button calls
showPanel(EditIssue, ...) directly — same path onIssueOpen takes for
sidebar-click and double-click.

Subject: [PATCH 198/388] fix(tracker-resources): move Gantt toolbar to second
 header row + webpack-safe icon imports
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two follow-up fixes after the initial Phase-2 toolbar consolidation:

1. The Gantt date-nav + zoom buttons landed in the FIRST header row
   (header-tools slot, next to the breadcrumb + ViewletSelector).
   User feedback: they belong with the Filter/Search/All-Active-Backlog
   row that sits below the title bar. Move from 'header-tools' slot
   to 'extra' slot — same row as the ModeSelector (All/Active/Backlog),
   one level below the breadcrumb.

2. svelte-check passed with '../icons/ArrowLeft.svelte' style imports
   thanks to TypeScript path mapping, but webpack rejected them with
   'Module not found'. Switch to the explicit
   '@hcengineering/ui/src/components/icons/...' import path that the
   rest of GanttView.svelte already uses.

 component
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lightweight inline editor surfaced by single-click on a Gantt bar.
Reuses StatusEditor, PriorityEditor, AssigneeEditor, StartDateEditor,
DueDateEditor so inline editing behaviour matches the full editor.
'Open full editor' button dispatches close with 'openFull' payload;
caller routes that to showPanel(EditIssue, ...).

Not yet wired into GanttView — that follows in the next commit.

 from migration.ts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

addGanttPhase1ViewOptions relies on view.class.Viewlet for its findAll
call, but doesn't use the Viewlet type directly — TypeScript infers the
return type from the class reference. The explicit 'type Viewlet' was
left over from an earlier draft and is dead code.

Subject: [PATCH 201/388] fix(tracker-resources): disable 'Open Sub Issues'
 button when no sub-issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Open-Sub-Issues button navigated to a filter view that would be
empty when the issue had no sub-issues — wasted click + dead-end UX.
Disable the button when size === 0 (size is the live count, updated
from QueryIssuesList's 'docs' event and initialised from issue.subIssues
on mount). The tooltip still shows on hover so users see what the
disabled button would do.

 ControlPanel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirror of DueDateEditor for the new optional deadline field on Issue.
Appears immediately under Due-date in the Issue's right-side control
panel. Uses a typed intersection cast (Issue & { deadline? }) because
the public Issue interface does not yet expose deadline — only the
TIssue model class does.

 viewlet.IssueGantt declaration

fix), the mergeIds call in plugins/tracker-resources/src/plugin.ts
attempted to add the same id again and threw 'identify overwrites
IssueGantt for tracker:viewlet' at bundle time, breaking pod-server's
get-model step.

Remove the resources-side declaration; the model-side declaration is
the single source of truth, and the runtime registration in
models/tracker/src/viewlets.ts:728 (createDoc(... tracker.viewlet.IssueGantt))
populates the same id through mergeIds when the resources plugin
loads.

Subject: [PATCH 204/388] refactor(tracker-resources): drop gantt-toolbar
 Filter button, use FilterBar as single source

The Phase-3b gantt-toolbar Filter button + popup duplicated the standard
Tracker FilterBar (in IssuesView.svelte's second header row) and led to
two disjoint filter-state sets per session. The FilterBar's resultQuery
already flows into GanttView via the query prop and is applied at the
issueQuery layer, so the gantt-local priority-chips popup added nothing
besides confusion.

Removes the toolbar button + popup markup, the ganttFilter / filterCount
/ filterPopupOpen state, the GanttFilter helpers (clearFilter,
toggleFilterValue), the filtered-issues client-side pass (now an alias
for issues), the unused .gantt-filter-* CSS, and the Ctrl+F binding
(which now falls through to the browser's native find). lib/filter-
predicate.ts is retained as ad-hoc helper for future use.

 as Urgent/High/Medium/Low
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

v121 user-feedback: the Gantt filter popup listed priorities as P0..P4 —
the raw enum index. Switch to the IssuePriority enum members + the
tracker.string i18n labels via the bundled issuePriorities map so users
see Urgent / High / Medium / Low / No Priority, consistent with every
other priority surface in tracker-resources.

Subject: [PATCH 206/388] feat(tracker-resources): thread nameLookup map
 through group-by helpers

v121 user-feedback: group-headers in Gantt sidebar rendered raw Mongo-style
ids for Component/Milestone/Label/Status, and numeric P0..P4 for Priority.
Add an optional id->display-name map to getGroupLabel and buildGroupedRows
so the UI layer can resolve real names while the helper stays pure.
Sentinel labels (No component / No milestone / ...) are unchanged.

 buttons in Gantt mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ViewletSettingButton renders two icon buttons (ViewOptions + Configure)
that both carry the 'Customize View' tooltip. In Gantt mode the
Configure popup edits list-only field config and the ViewOptions popup's
groupBy/orderBy never drive the Gantt rendering — Gantt has its own
Filter/Group-by/Sort/Tree-View/Virtualization toolbar inside GanttView.

Suppress the standard buttons for the Gantt descriptor and resolve
viewOptions inline so ViewletContentView still mounts the Gantt
component on first render.

Subject: [PATCH 208/388] fix(tracker-resources): freeze Gantt drag preview
 while confirm popup is open

The drag commit popups (GanttConfirmCommitPopup, ConfirmCascadePopup)
are non-modal, so the window-level pointer listeners that GanttView
attaches during a drag stayed wired the whole time the popup was up.

Two visible bugs in v121.1:
  - Hover-bug (single + bulk): pointermove kept calling the drag
    reducer, so the preview bar trailed the cursor while the user was
    looking at the popup.
  - Double-popup-bug: the Cancel/Apply button mouseup bubbled to the
    window and re-entered handleCanvasPointerUp while activeDrag was
    still in dragging-body, opening a second popup on top of the first.

Introduce a module-scope confirm-gate flag and short-circuit both
handleCanvasPointerMove and handleCanvasPointerUp while it is set.
Every commit path that opens a confirmation popup (legacy single,
multi-primary, cascade, permission-denied) toggles the flag on
before showPopup and off in the result handler.

+ * v121.2 fix — drag-commit confirmation gate.
+ *
+ * Background. After a Gantt bar drag ends, the user-configurable
+ * confirmation popup (GanttConfirmCommitPopup or ConfirmCascadePopup)
+ * runs as a non-modal showPopup. The window-level pointer listeners that
+ * GanttView attaches while the drag is active stay wired the whole time
+ * the popup is open — which produced two bugs reported in v121.1:
+ *
+ *   1. Hover-bug: pointermove kept calling the drag reducer, so the bar
+ *      visually trailed the cursor while the popup was up.
+ *   2. Double-popup-bug: clicking the popup's Cancel/Apply button bubbled
+ *      pointerup to window, which re-entered handleCanvasPointerUp while
+ *      activeDrag was still in `dragging-body` — opening a second popup.
+ *
+ * This module is a tiny module-scope flag. GanttView toggles it on
+ * before showing a confirmation popup and off when the popup resolves.
+ * The pointer handlers consult {@link isConfirming} to short-circuit.
+ *
+ * The flag is module-scope (not store-based) on purpose — there is only
+ * ever one drag in flight, the consumer is GanttView, and the flag is
+ * always set/cleared inside the same async commit path. A Svelte store
+ * would force a reactive cycle through `$:` blocks for a guard that
+ * needs to be read synchronously inside event handlers.

Subject: [PATCH 209/388] fix(models/tracker): declare viewlet.IssueGantt in
 model plugin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

viewlets.ts:728 reference tracker.viewlet.IssueGantt, but the model
plugin (models/tracker/src/plugin.ts) only declares IssueList,
IssueTemplateList, IssueKanban, MilestoneList, ComponentList,
ProjectList, ProjectListGrouped.

The IssueGantt id was only declared in the frontend plugin
(plugins/tracker-resources/src/plugin.ts) via mergeIds at runtime.
Model code accessed an undeclared field — TypeScript allowed it via
the indexable Plugin.viewlet record type, but the access returned
the default empty string at model-build time. createDoc(...,
tracker.viewlet.IssueGantt) therefore produced a Viewlet doc with an
empty _id, and migration findAll({_id: ''}) returned nothing — making
the Phase-1 ViewOption migration a silent no-op on first install.

Add IssueGantt: '' as Ref<Viewlet> to the model plugin viewlet
namespace so the id is consistent across model and frontend.

Subject: [PATCH 210/388] feat(tracker-resources): continuous Ctrl+Wheel zoom
 over gantt canvas

Adds a continuous pixelsPerDay knob on top of the four Day/Week/Month/
Quarter presets. Ctrl+Wheel (Cmd+Wheel on Mac) over the gantt scroller
zooms exponentially with the date under the cursor anchored, clamped to
[0.05 .. 200] px/day. The preset buttons still snap to canonical
pxPerDay values and clear the override; while in continuous-zoom mode
the toolbar highlights the closest preset with a softer style so the
two states are visually distinguishable.

Tick granularity (Day/Week/Month/Quarter) is derived from pxPerDay so
zoomed-out views automatically switch to coarser ticks. All math lives
in lib/zoom.ts (25 new unit tests) so the cursor-anchor + clamp
behaviour is regression-tested independent of DOM.

Subject: [PATCH 211/388] fix(tracker-resources): align Gantt extended sidebar
 grid width and sticky header

When ganttSidebarColumnsExtended is on, the outer sidebar-cell was sized
by the legacy slider while the inner grid summed per-column widths, so
the extended columns spilled out of the sidebar onto the canvas and the
column headings scrolled away inside the body cell instead of staying
pinned to the top.

Drive sidebarWidthPx from computeTotalWidth(columns, widths) in extended
mode, clip the sidebar-cell defensively, and render the sortable/
resizable header inside the sticky corner cell via a headerOnly variant
of GanttSidebar. Legacy compact mode is unchanged.

Subject: [PATCH 212/388] fix(tracker-resources): reserve body padding in
 cascade confirm popup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The bulk-move confirm popup's bodyHeight matched the SVG content height
exactly but ignored the .body element's 4 px top/bottom CSS padding, so
the scroller clipped the bottom 8 px of the last row — visible as a
sliced-off bar in the v121.1 'N issues will be shifted' render with
three primary edits.

Fold the padding plus a small safety margin into the computed height
via a pure cascade-popup-layout helper. The popup now grows to fit the
typical N<10 case without scrolling and only scrolls once the timeline
genuinely exceeds the BODY_MAX_HEIGHT ceiling.

Subject: [PATCH 213/388] fix(tracker-resources): drop duplicate Phase-1 Gantt
 toolbar to unblock PNG/PDF export

v121 user-feedback: PNG/PDF export buttons did not produce real downloads.
The IssuesView 'extra' slot used to render a second toolbar row
(GanttToolbarControls + GanttExtraActions) that talked to GanttView via
the ganttToolbarApi store, but those buttons routed PNG through the
deprecated SVG-only path and were never wired to a working PDF exporter.
The Tier-stack toolbar inside GanttView already exposes the same affordances
backed by exportElementAndDownloadPng / exportElementToPdf (html2canvas +
jsPDF), so removing the legacy components leaves a single working code path
and stops the duplicate buttons reported in v121 tests.

+ * Tier-2 Item 8 — Activity-Log Remove-Detail Fix.
+ *
+ * Legacy IssueRelation removals went through `ops.removeDoc`, which emits
+ * a bare TxRemoveDoc without parent-issue attachment. The activity
+ * pipeline therefore wrote a DocUpdateMessage whose attachedTo is the
+ * relation itself, never showing up in the issue's activity feed. This
+ * migration re-attaches such DUMs to their parent issue by looking up the
+ * original TxCreateDoc of the now-removed IssueRelation. Best-effort:
+ * when the create-tx is missing (db compaction) the DUM still gets
+ * `updateCollection='relations'` so the activity feed at least shows
+ * "removed dependency" without the target detail.
+ *
+ * Idempotent — once a DUM has Issue-side attachment + `updateCollection`,
+ * the predicate skips it on subsequent runs. The predicate is a local
+ * 4-LOC copy of `isBrokenRelationDum` in
+ * `plugins/tracker-resources/src/components/gantt/lib/relation-activity-migration.ts`
+ * (cannot import across package layers — models/tracker is below
+ * tracker-resources). The helper module is the one with unit tests.

Subject: [PATCH 216/388] feat(tracker-resources): add mobile-friendly Gantt
 pure-logic helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds four pure helpers + 56 unit tests for the Mobile-Friendly Gantt
work (Spec 2026-05-14):

- breakpoint.ts        — LayoutMode detection (phone/tablet/desktop)
                         with ≤640 / 641-1024 / >1024 thresholds
- pointer-classify.ts  — Tablet-voll / Phone-read-only routing matrix
                         (allow / long-press / block per pointerType+action)
- long-press.ts        — 300 ms long-press state machine with 10 px
                         movement-cancel threshold
- pinch-zoom.ts        — 2-pointer pinch tracker with stable captured
                         center + distance ratio → pxPerDay mapping,
                         clamped to the same MIN/MAX as Ctrl+Wheel zoom

No DOM or timer access in any helper; all 4 modules are pure reducers
or math. Touch-events are partially supported in jsdom, but the pure-
logic level is fully covered. Tests: 575 → 631 (+56).

Subject: [PATCH 217/388] fix(tracker-resources): widen row/col to number in
 diagramGridIndex

The literal-union casts ('-1 | 0 | 1') tripped svelte-check while the
runtime range-check (row < 0 || row > 1) is still correct. Switch the
locals to plain number to drop the unsound assertions.

Subject: [PATCH 220/388] feat(tracker-resources): add predecessor-list-format
 helper

Pure helper for the upcoming Tracker-List Predecessors column:
- formatPredecessorEntry(rel, source) -> 'PROJ-3 FS+2d'
- sortPredecessorsByIdentifier(rels, sourceMap) -> sorted entries
  with numeric-aware localeCompare (PROJ-2 < PROJ-10) and silent
  drop of orphan relations whose source Issue was deleted
- splitFirstAndRest(sorted) -> { first, rest, extraCount } for the
  'first + N more' rendering pattern from the spec

13 unit tests, total: 518 -> 531.

Subject: [PATCH 224/388] feat(tracker-resources): wire layoutMode + pinch-zoom
 into GanttView
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the runtime wiring for the Mobile-Friendly Gantt:

- layoutMode state driven by window.innerWidth on mount + on resize.
  Phone (≤640) sets phoneReadOnly true; tablet/desktop stay full-edit.
- Pinch-zoom handlers (down/move/up/cancel) attached to the canvas
  scroller alongside the existing pan handlers. Touch-only (mouse/pen
  fall through to existing pan + Ctrl+Wheel zoom paths). Uses
  cursorAnchoredScrollLeft so the pinch midpoint stays anchored under
  the user's fingers as ppd changes — same math as Ctrl+Wheel zoom.
- iOS Safari pointercancel cleanly resets the pinch state machine so
  scroll-inertia doesn't leave a half-tracked pinch behind.

No UI surface change yet; the drawer + hamburger come next.

Subject: [PATCH 225/388] feat(tracker-resources): GanttBar pointer-only events
 + long-press routing

Removes the legacy on:mousedown handlers from GanttBar (body + summary
+ resize handles) and routes everything through on:pointerdown via the
classifyPointer matrix:

  - mouse/pen on any layout    -> direct dispatch (legacy behaviour)
  - touch on Phone (any action)-> blocked (read-only)
  - touch on Tablet/Desktop    -> 300 ms long-press, cancels on >10 px
                                  movement or early pointerup

Pre-Flight (Item 9) called out the Touch double-event race (mouse and
pointer both fired); now there is exactly one event-source per gesture.
layoutMode is threaded through GanttCanvas to GanttBar; GanttView forces
editableIssueIds to an empty set when layoutMode === 'phone' so the
Set-driven gates in GanttCanvas all fail closed without per-callsite
changes.

Tests: 631 / 631 still green. svelte-check: 0 errors.

Subject: [PATCH 226/388] fix(models/tracker): use
 trackerModel.viewlet.IssueGantt in migration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

migration.ts imports tracker from '@hcengineering/tracker' (public
plugin) which does not declare a viewlet namespace. The IssueGantt
viewlet id is declared in models/tracker/src/plugin.ts and accessed
via mergeIds at runtime, but TypeScript does not know that.

on tracker.viewlet.IssueGantt — verified locally. Import the model-
local plugin via 'trackerModel' alias and reference IssueGantt
through it. rush validate is now green.

Subject: [PATCH 227/388] fix(tracker-resources): wrap gantt toolbar on tablet
 viewports

The gantt toolbar uses a rigid 3-column CSS Grid (1fr auto 1fr) with a
fixed 40px height, which on monitors <=1024px clipped the right cluster
(undo/redo/saved-views/group-by/PNG/PDF/fullscreen) or pushed the zoom
chips into the left cluster.

Below 1024px the toolbar now switches to display:flex with flex-wrap,
and each cluster (left/center/right) wraps inside itself. The inline
`height: 40px` was changed to `min-height` and the measured client
height is bound into `toolbarHeightPx` so the overlaid vertical
scrollbar still starts directly below the toolbar when it grows to two
rows. Phone (<=640px) keeps the existing mobile-drawer flow.

Subject: [PATCH 228/388] fix(tracker-resources): data-driven PNG/PDF export
 with full sidebar + chart

Replace html2canvas DOM-screenshot approach with a data-driven SVG
renderer that builds the export image from sortedRows, displayedRelations,
summaryRanges, timeScale, range, and totalCanvasWidth.

The old html2canvas approach failed because the Gantt's sidebar/canvas
are virtualised, internally scrolled, and horizontally translateX-shifted.
The screenshot captured only the visible viewport or rendered emptiness.

New approach in lib/export-renderer.ts:
- Builds a standalone SVG with Issue-list on the left and the full Gantt
  chart on the right, including bars and dependency arrows.
- PNG: SVG -> Canvas -> PNG blob -> &lt;a download&gt; (real file download)
- PDF: same SVG -> high-res PNG -> jsPDF with custom page size (not a
  browser print of the page).
- GanttView buttons now call exportGanttDataToPng / exportGanttDataToPdf.
- Regression test export-renderer.test.ts verifies issue-list ordering
  before chart + dependency-arrow output.

Tests: 631 -> 633 green. svelte-check clean. Build clean.

Reported root cause + fix in /opt/infrastructure/docs/operations-memory/2026-05.md.

Subject: [PATCH 229/388] fix(tracker-resources): replace gantt tree glyphs
 with ChevronRight/Down icons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The toolbar expand-/collapse-all buttons rendered "▶▶" / "▼▼" double
carets which QA flagged as confusing — they read more like a
fast-forward / jump-to-today affordance than a hierarchy toggle. The
single ▶ / ▼ text glyphs in the sidebar tree-rows suffered from the
same problem at small font sizes.

Replace both with the standard `IconChevronRight` / `IconChevronDown`
icons re-exported from `@hcengineering/ui` (same icons used in
AccordionItem, NestedSelectPopup and the calendar month-picker, so
the affordance is consistent across the platform).  The now-unused
`.gantt-tree-glyph` CSS rule is removed.

Subject: [PATCH 232/388] feat(tracker-resources): add Estimation row to gantt
 quick-info popover

Phase 1.E shipped the quick-info popover with Status / Priority /
Assignee / StartDate / DueDate inline editors.  The Gantt spec also
lists Estimation as part of the popover surface but it was missing
from the implementation.

Add an Estimation row that reuses the existing EstimationEditor from
issues/timereport/.  Click on the link opens the same EstimationPopup
the full editor uses, so update semantics (manhours / story points /
formatted display) stay identical.

Subject: [PATCH 233/388] fix(tracker-resources): add xmlns to gantt canvas svg
 root

When the GanttCanvas SVG is serialized into a standalone .svg file
(e.g. via XMLSerializer in export paths) the resulting blob must
declare the SVG namespace or browsers/PDF renderers reject it. The
in-DOM HTML parser tolerates the missing attribute, but external
consumers do not.

exporter.ts already patches xmlns onto a clone before serialization;
adding it on the source removes that fallback dependency and makes
any direct outerHTML/XMLSerializer dump valid standalone SVG.

Subject: [PATCH 234/388] refactor(tracker-resources): replace hex colors in
 gantt with theme variables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hardcoded hex values (#dc2626, #10b981, #f59e0b, #3b82f6, #94a3b8, …)
in GanttBar, GanttCanvas, StatusBadge, GanttDependencyArrow,
GanttDependencyLayer, GanttConnectorDot, GanttSidebar, GanttSidebarColumn
don't react to Huly's dark/light theme and would glare in dark mode.

Map to existing theme vars:
- red/critical/violated/overdue → --theme-state-negative-color
- green/won status → --theme-state-positive-color
- orange/active/warning → --theme-warning-color
- blue/todo/primary → --theme-state-primary-color
- grey/neutral/backlog/slack → --theme-state-regular-color
- indigo connector dot keeps the existing --theme-state-info-color
  fallback pattern (no canonical var exists yet)

Known limitation: ConfirmCascadePopup illustration colors and the
export-renderer/exporter SVG output keep hex literals — the popup is
a fixed-palette diagram, and exported SVG/PNG must be self-contained
(theme vars wouldn't resolve outside Huly).

Subject: [PATCH 235/388] fix(tracker-resources): keep both Customize-View +
 Configure-Columns in Gantt mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

User-Report 2026-05-15: Im Gantt-Mode wird nur 'Configure Columns'
angezeigt (was Spalten fuer die Extended-Sidebar konfiguriert) aber
'Customize View' fehlt — und genau in 'Customize View' liegen die
Bar-Labels und anderen Gantt-relevanten ViewOptions, die der User
braucht.

Wurzel: v121.12 Refactor B hat das FALSCHE versteckt — der
ViewOptionsButton (mit Bar-Labels) wurde rausgenommen, aber genau der
sollte BLEIBEN. Mein Mental-Model zur Refactor-Zeit war invertiert.

Beide Buttons haben in Gantt-Mode echte Funktionen:
- 'Customize view'  (sliders)  → Bar-Labels + ganttQuickInfoOnClick +
                                  ganttSidebarColumnsExtended +
                                  ganttBarLabelLeft/Inside/Right etc.
- 'Configure columns' (eye)    → Phase-3a Extended-Sidebar Spalten-
                                  Konfiguration

Fix: showViewOptions-Prop entfernt, beide Buttons immer sichtbar.
Wording-Split (Customize view vs Configure columns) bleibt.

Subject: [PATCH 238/388] fix(view+card-resources): apply ConfigureColumns
 tooltip to all Configure-button instances
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

User reported v121.12 Refactor B (Customize-View vs Configure-Columns split)
ist nicht durchgängig — die Anzeige stimmt in Listen- und Card-View
weiterhin nicht.

Wurzel: Es gibt DREI separate Components mit derselben 'ViewOptionsButton
plus Configure-ButtonIcon' Logik, aber Refactor B fixte nur EINE:

- view-resources/.../ViewletSettingButton.svelte (singular) ✅ v121.12
- view-resources/.../ViewletsSettingButton.svelte (plural)  ❌ verbleibend
- card-resources/.../ViewSettingButton.svelte (Card-View)   ❌ verbleibend

Die beiden verbleibenden Components zeigten ihren Configure-ButtonIcon noch
mit 'CustomizeView' Tooltip statt 'ConfigureColumns', d.h. Sub-Issue-Liste
(QueryIssuesList) + MeetingMinutes + VacancyApplications + Card-View
hatten weiterhin BEIDE Buttons mit demselben 'Customize View'-Tooltip.

Fix: beide auf view.string.ConfigureColumns umstellen — gleicher
IntlString-Key der bereits in v121.12 in plugins/view-assets/lang/{en,de}.json
+ 11 weitere Locales gepflegt wurde.

Subject: [PATCH 239/388] fix(tracker-resources): close GanttSaveViewPopup on
 X-click via onCancel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The platform Card.svelte routes X-click through an optional onCancel
prop and only falls back to dispatch('close') when onCancel is unset.
GanttSaveViewPopup was relying on the dispatch path with a wrapping
<Card on:close={...}> forwarder, which empirically did not close the
popup in v121.11 (user report). Wire onCancel explicitly so X-click
calls dispatch('close') directly on the popup component, bypassing
the Card→handler→re-dispatch chain that wasn't reaching PopupInstance.

OK-button continues to dispatch close{detail} from onSave so the
caller in GanttView.openSaveViewPopup() still receives the form
payload synchronously before Card's tail-close fires.

Subject: [PATCH 240/388] feat(tracker-resources): collapse 4 zoom-preset
 buttons into Dropdown + numeric days-input

Replace the legacy Day/Week/Month/Quarter button row in the Gantt
toolbar-center with a single DropdownLabelsIntl + a numeric EditBox
showing the currently visible day-count.

- New helper lib/zoom-dropdown.ts with three pure functions:
  - dropdownSelectionForPxPerDay() maps userPxPerDay+zoom to one of
    day/week/month/quarter/custom with an EPSILON_PPD tolerance.
  - visibleDaysFromPxPerDay() / pxPerDayFromVisibleDays() are mutual
    inverses around the viewport width; defensive against NaN/zero.
- Custom is never directly selectable from the dropdown: the entry is
  only inserted while wheel-zoom has placed userPxPerDay off-preset, so
  clicking the dropdown still reflects the active state but does not
  offer Custom as a no-op pick.
- Editing the days-input drives userPxPerDay = width/days, which flips
  the dropdown to Custom (unless the value happens to land on a preset).
- Keyboard shortcuts D/W/M/Q and Ctrl+Wheel keep their existing wiring.

IntlStrings: GanttZoomDay/Week/Month/Quarter/Custom + GanttZoomLabel +
GanttZoomVisibleDays (plural) + GanttZoomDaysSuffix/Aria, in EN and DE.

Tests: tracker-resources jest 633 -> 645 (12 new in zoom-dropdown).
svelte-check: 0 errors.

Subject: [PATCH 241/388] refactor(view-resources): remove dead showViewOptions
 prop from ViewletSettingButton

v121.16 reverted v121.12 #B's only call-site override, leaving the prop
with default true and no remaining caller. Drop the prop and the
{#if showViewOptions} guard; ViewOptionsButton now renders whenever the
viewlet supplies viewOptions, matching observable behaviour since v121.16.

Tracked in 2026-05-15 regression audit, item Bug-1.

Subject: [PATCH 243/388] fix(tracker-resources): replace gantt dblclick on
 mobile with quick-info open-editor button
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

iOS/Android intercept double-tap for system zoom, which collides with
the gantt 'dblclick → open full editor' shortcut and makes opening
issues unreliable on phones.

Phone layout now:
- drops the dblclick handler on bar-wrap groups (still active on tablet/desktop);
- force-enables ganttQuickInfoOnClick regardless of the user's view option
  so the quick-info popover is always reachable via single tap;
- routes the popover's existing 'Open full editor' button through the
  same showPanel(EditIssue) call the desktop dblclick uses.

Result: mobile users get a deterministic single-tap → quick-info →
'Open full editor' path with no system-zoom interference, while
desktop/tablet behaviour is unchanged.

Subject: [PATCH 244/388] docs(tracker-resources): document gantt bar
 tabindex=-1 + manual focus handler

An external code review flagged GanttBar's tabindex="-1" + svelte-ignore as a
potential upstream-review red flag. The behaviour is intentional: focus
management is centralised in GanttView.onKey (Tab/Shift-Tab cycles
scheduledIssues in visual order, Arrows shift focused bar). Native
per-rect Tab navigation would cycle in DOM order which doesn't match
chart order, so we route everything through moveFocus() instead.

Spell that contract out in a block comment above the non-summary bar
<rect>, mirroring the existing summary-path comment, with a pointer to
the canonical handler location in GanttView.svelte. Pure documentation,
no runtime change.

Tabindex="0" + native browser focus order remains a possible follow-up
if upstream requests it; leaving as Option-A (documentation) per
v121.19 task scope.

Subject: [PATCH 245/388] fix(tracker-resources): restore gantt files and lost
 strings post-rebase

Rebase --onto upstream/develop introduced conflicts that were resolved
by keeping HEAD versions, losing content from later commits in the
branch history. Fixed:

- Restore all gantt/*.svelte and lib/*.ts to pre-rebase-backup state
  (upstream/develop does not touch the gantt directory)
- Remove duplicate function bodies in scheduler.ts and drag-controller.ts
- Restore 71 missing ViewOptions in models/tracker/src/viewlets.ts
- Add missing @hcengineering/notification dep to plugins/tracker/package.json
- Restore missing IntlStrings in tracker plugin index.ts (Deadline,
  BarLabel*, GanttBarLabel*, GanttQuickInfoOnClick, GanttSavedView*,
  GanttMobile*, GanttExport*, GanttFullscreen, GanttMoreActions,
  QuickInfoOpenFullEditor, DependencyShifted*)
- Restore 27 missing en/de lang strings (GanttSavedView*, GanttMobile*,
  GanttExport*, GanttFullscreen, GanttMoreActions)
- Fix trackerModel -> tracker in models/tracker/src/migration.ts
- Restore 31 missing strings in tracker-resources/src/plugin.ts
- Add DeadlineEditor usage back in ControlPanel.svelte

Subject: [PATCH 248/388] fix(tracker-resources): add missing lib modules +
 type fixes for svelte-check pass

Add missing pure-logic modules (bulk-boundary, bulk-selection, dependency-shift-send,
dependency-shift-notify, flash-store, gantt-view-options, saved-views, tree-expand-store,
undo-manager, y-viewport) that GanttView.svelte imports.

Fix dependency-router.ts to include full ArrowVisibility/YBounds/clippedEndpointPx exports.
Add multiSelectedIssueIds + layoutMode props to GanttCanvas.
Add hasDeadline/isOverdue import to GanttCanvas.
Fix GanttBar resize handles to use on:pointerdown instead of undefined on:mousedown.
Add coDrag field to DragEvent mousedown-bar and DragState dragging-body types.
Add ShiftedIssuePayload + DependencyShiftedNotification interfaces to tracker plugin.
Add GanttExpandAll/GanttCollapseAll/GanttTreeBreadcrumb i18n strings.

+ * Tier-4 Item 14 — Notification on Dependency-Shift.

+ * Client-side dispatcher: takes a freshly-committed cascade result and emits
+ * one `DependencyShiftedNotification` per (non-trigger) recipient. The send
+ * runs after `ops.commit()` succeeds in `GanttView.svelte:commitCascadeBatch`
+ * (and the alt-bypass + no-cascade-with-shifts code paths), so a failed
+ * commit never produces a phantom notification.
+ *
+ * Architecture notes:
+ *
+ *  - The bundle does NOT go through the server-side `pushInboxNotifications`
+ *    pipeline because that pipeline is keyed off TxCUD context for the
+ *    *originating* doc — we'd lose the trigger-user / cascade-set context.
+ *    Creating the notification doc directly is the simplest path that keeps
+ *    the bundle payload intact end-to-end.
+ *
+ *  - Suppression of the auto-generated `dueDate` notification (spec §3.3) is
+ *    a Known Limitation in v1: `TxApplyIf.scope` (= `cascadeToken`) is
+ *    consumed inside `ApplyTxMiddleware` before the trigger pipeline sees
+ *    the inner Txes, so a server-side trigger cannot tell a cascade update
+ *    apart from a manual edit. Follow-up: surface the cascade-token through
+ *    a trigger-visible attribute or wrap the cascade Tx in a custom Tx-mixin.
+ *
+ *  - The `DocNotifyContext` that normally accompanies an inbox notification
+ *    is intentionally omitted in v1; the recipient sees the entry in their
+ *    inbox via the `user` + `space` routing keys on the notification
+ *    itself, which is the same path `MentionInboxNotification` relies on.

+ * the Set get a transient highlight (gepunktete outline). The UndoManager
+ * pushes IDs into the store on successful undo/redo, and the timer below
+ * removes them after `durationMs`.
+ *
+ * Per-id timers are tracked so that overlapping flashes don't truncate each
+ * other: a second `flashIssues(['x'], …)` while `x` is already flashing
+ * cancels the pending timeout and schedules a fresh one starting from the
+ * second call.
+ *
+ * The store implements the minimal Svelte contract (`subscribe`) so that
+ * GanttView / GanttBar can use `$flashStore` syntax — without dragging in
+ * `svelte/store`, which is ESM-only and breaks jest-ts-jest in this repo.

+ *     keyed **per project** so cross-project navigation does not bleed state.
+ *   - Default is **expanded** — the persisted value records *only* deviations
+ *     (i.e. the row-ids the user has explicitly collapsed), so an unseen issue
+ *     is implicitly expanded.
+ *
+ * Storage backend is the `Storage` interface (browser `localStorage` in
+ * production, an in-memory shim in unit tests). The spec mentions a future
+ * migration to `@hcengineering/preference`-backed docs; the store-API here is
+ * deliberately backend-agnostic so the swap is a one-file change.
+ *
+ * Failure modes:
+ *   - corrupt JSON / non-array values → treated as "no persisted state"
+ *     (the user simply gets the default-expanded view, no exception thrown).
+ *   - `setItem` throwing (quota exceeded, private mode) → caught and ignored;

+ * Phase 3c — Gantt undo/redo manager.
+ *
+ * One instance per `GanttView` mount. The manager keeps two LIFO stacks of
+ * `UndoEntry` snapshots; each Gantt-induced mutation pushes an entry after
+ * the DB-write commits successfully. `Cmd+Z` / `Ctrl+Z` pops the top entry
+ * and applies its inverse via `client.apply(undefined, 'gantt-undo')` so the
+ * activity log can later be filtered by that marker.
+ *
+ * The "stores" exposed below implement the minimal Svelte subscription
+ * contract so callers (`GanttView.svelte`) can use `$canUndo` etc. without
+ * pulling in `svelte/store` (ESM-only, incompatible with the project's
+ * ts-jest setup — see plugins/tracker-resources/src/components/gantt/lib/
+ * flash-store.ts for the same rationale).
+ *
+ * Spec: /opt/infrastructure/docs/superpowers/specs/2026-05-14-huly-gantt-undo-redo-design.md

Subject: [PATCH 249/388] fix(tracker-resources): make Ctrl+Wheel zoom work in
 month and quarter

At low pixels-per-day densities (month=4, quarter=1.5) the chart fits in
the viewport with no horizontal overflow, so the custom h-scrollbar
element is not rendered. The wheel-zoom handler early-returned on the
missing element, leaving Ctrl+Wheel a no-op in those zoom levels.

Fall back to scrollerEl for the cursor-anchor bounding box and skip the
scrollLeft-anchor step entirely when there is no overflow (nothing to
scroll). Wheel-zoom now works at every density.

Also introduce adaptiveWheelFactor: 0.012 for ppd<4 (month/quarter),
0.006 for ppd>=4 (week/day). Exponential math is multiplicatively
adaptive, but in the low-density bands the absolute pixel delta per
notch is small enough that users perceive the same exp step as slower
than at high density. The bumped factor restores subjectively equal
responsiveness across all four presets.

Five new unit tests cover the factor boundaries and the
adaptive-vs-fixed contrast at ppd=1.5 and ppd=14.

Subject: [PATCH 250/388] fix(view-resources): hide group-by/sort in
 ViewOptions popup when viewlet renders its own
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The shared View-Options popup renders a Group-by + Order-by dropdown pair
plus a list of viewlet-specific toggles (bar labels, confirm dialogs,
etc.). In Gantt mode the toolbar already provides its own dedicated
group-by and order-by dropdowns wired to the Gantt-internal layout, so
the popup's pair is visually duplicated and not wired to anything — users
see the same control twice and changing the popup version has no effect.

Add a hideGroupingAndOrdering prop that propagates from
ViewletSettingButton → ViewOptionsButton → ViewOptions. When true the
popup skips its grouping and ordering rows (plus the separator before
the toggles) and renders only the 'other' toggles, which remain wired.

IssuesView passes hideGroupingAndOrdering=isGanttMode so list mode keeps
the previous behaviour and Gantt mode shows only the useful toggles.

Subject: [PATCH 251/388] chore(tracker-resources): scrub internal tier/version
 markers from inline comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Strips internal-tracking phrases from source-code comments: Tier-N Item M,
Tier-N #M, v121.NN, per Tier-N spec, plus leftover internal review markers
mentions. The comments themselves are preserved — only the attribution
labels are dropped so the noted constraint or hidden invariant survives.

Subject: [PATCH 252/388] feat(tracker-resources): wire per-column toggles for
 extended Gantt sidebar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The Extended Sidebar toggle (ganttSidebarColumnsExtended) used to ship a
hardcoded identifier/title/predecessors/slack quartet with no UI to add
the other supported columns. The Configure-Columns button is generic
viewlet-config and has no effect on the Gantt sidebar.

Add 8 per-column ViewOption toggles under the Extended Sidebar toggle in
the Customize-View popup: Status / Priority / Assignee / Estimation /
StartDate / DueDate / Deadline / Progress. Each toggle appends its
column to the default set; the order matches the natural reading order
on the sidebar (status..progress..predecessors..slack). Toggles are
collapsed when the Extended Sidebar toggle is off so the popup does not
grow indefinitely.

Also raises the sidebar size limits: total width 600→1200 px,
per-column width cap 400→600 px, so the extra columns actually have
room to render.

Finally adds a showConfigureColumns prop on ViewletSettingButton
(default true). IssuesView passes false in Gantt mode so the
configure-columns icon no longer renders there — it had no effect on
the Gantt sidebar anyway.

Subject: [PATCH 253/388] fix(gantt): left-align corner-range
 collapse/expand-all buttons
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After the PR3a refactor dropped the duplicate \« \» date-nav buttons from
the corner-range, the remaining tree-toggle buttons (collapse-all,
expand-all) still inherited the old `justify-content: center` and
ended up visually floating in the middle of the corner cell. Switch to
`flex-start` so the buttons hug the left edge of the sidebar grid,
matching the alignment of the column-toggle chevrons in the rows below.

Subject: [PATCH 254/388] fix(tracker-resources): resolve eslint errors and
 apply formatting for gantt polish tier

Reviewer-approved fix patterns applied to the pre-existing eslint errors the
CI formatting job surfaces in the PR4 polish-tier code, alongside the prettier /
eslint --fix normalisation after the develop merge:
- no-confusing-void-expression: block-body arrows / drop redundant void operator
  (GanttCanvas dblclick, GanttView reactive recompute);
- no-non-null-assertion: drop redundant `!` on already-any-cast dragTarget;
- strict-boolean-expressions: explicit nullish handling in exporter;
- no-case-declarations: brace case blocks with lexical declarations (bar-labels);
- naming-convention: __resetConfirmGate -> resetConfirmGate (test reset helper);
- require-array-sort-compare: explicit localeCompare in build-rows test;
- balance the connector-overlay nested {#if} (prefer-optional-chain split) that
  the merge left one {/if} short.

From f2e2e5617ac08d8ad79e9c3eb622065025a7ecc5 Mon Sep 17 00:00:00 2001
From: Michael Uray <michaeluray@users.noreply.github.com>
Date: Fri, 3 Jul 2026 08:55:41 +0000
Subject: [PATCH 255/388] fix(tracker-resources): repair GanttView imports and
 exporter querySelector types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

svelte-check surfaced type errors from the cascade merge + eslint import
consolidation in the PR4 polish tier:
- './lib/types' merged into an `import type { ... }` with redundant inner
  `type` modifiers (invalid) — flatten to plain names;
- descendantsWithDates dropped from the './lib/scheduler' import (used in the
  scheduler/cascade paths) — restore it;
- getEventPositionElement dropped from the @hcengineering/ui import (used by
  openGanttMenu) — restore it;
- exporter expandForCapture passed Element (untyped querySelector) where
  HTMLElement is required — add the <HTMLElement> generic, matching the
  querySelectorAll call in the same function.

Signed-off-by: Michael Uray <michaeluray@users.noreply.github.com>

Subject: [PATCH 256/388] chore(tracker): reconcile Gantt sources after develop
 rebase

Re-materialize the exact intended tip content for Gantt component and
i18n files that were carried via merge commits. Linearizing onto the new
develop dropped those merges; develop does not touch these files.

Subject: [PATCH 265/388] fix(tracker-resources): undo conflict feedback +
 cascade-atomicity regression tests

Adds a GanttUndoConflictHint i18n string and surfaces it as the
notification sub-line when a Ctrl-Z gets dropped due to a conflict, so
users understand why repeated Ctrl-Z does not retry the same frame.
Both conflict and error paths now emit a console.warn with the original
UndoEntry to make intermittent 'undo did nothing' reports debuggable
in DevTools.

The cascade-frame atomicity was already wired (commitCascadeBatch pushes
one date-batch UndoEntry; applyInverse iterates inside one client.apply
scope so commit() is all-or-nothing). Adds 4 explicit regression tests
that pin that contract: 5-issue cascade applies in one commit, commit
throw leaves zero partial mutations, conflict drops the frame from the
stack without re-push, conflicted result carries the original entry
for the debug-log payload.

 markers from inline comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Strips internal-tracking phrases from source-code comments (Tier-N Item M,
Tier-N #M, v121.NN, per Tier-N spec, leftover internal review markers).
Comments themselves are preserved — only the attribution labels are dropped.

Subject: [PATCH 273/388] feat(tracker-resources): add sidebar-virtualization
 range helper for Phase 3a

Pure-logic computeVisibleRowRange returns the visible row index range plus
top/bottom spacer heights for a uniform-row-height virtual list. Stages
the data path the sidebar renderer will adopt in a follow-up to handle
1000+ rows under the new column system without breaking the canvas
scroll coupling. 10 unit tests cover edge cases (empty list, top/bottom
edges, overflow, rubber-band scroll, zero rowHeight).

Subject: [PATCH 274/388] deps(tracker-resources): add @tanstack/svelte-virtual
 for Gantt Y-axis virtualization

as the virtualization library (~50 KB minified, Apache-2.0). Headless virtualizer
will drive a single Y-viewport manager that the Gantt sidebar, canvas, and
dependency-arrow layer all subscribe to so the three layers stay scroll-synced
without re-implementing fixed-row-height math in each component.

 Gantt vertical virtualization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pure-logic Y-axis virtualization surface (computeYViewport, rowIndexToY,
yToRowIndex, sliceVisibleRows) — mirrors the runtime virtualizer's decisions
so the sidebar + canvas + dependency layer can be tested deterministically
without a browser. Supersedes Phase 3a's computeVisibleRowRange() helper as
the single source of truth for visible-range + spacer math.

 visibility against y-viewport
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Pure-logic classifyArrowVisibility() + clippedEndpointPx() helpers tell the
dependency layer which arrows to render in full, which to clip at the
viewport edge with an off-screen indicator, and which to cull. Both
endpoints on the same off-edge side → none. Endpoints straddling opposite
edges → both-off (arrow path still crosses the viewport). Single-pixel
overlap with bounds counts as visible.

Subject: [PATCH 277/388] test(tracker-resources): add 1000+5000-row y-viewport
 perf gates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Synthetic sweep over 100 / 50 scroll positions on a generated 1000 / 5000
row dataset. Budgets are loose (500 ms / 1500 ms) so the test doesn't
flake under rush parallel test execution; actual runtime is single-digit
ms on modern CPUs. The gate exists to flag catastrophic regressions
(10× slowdown) in the pure-logic virtualization path.

- * Phase 3b — Client-side Gantt filter predicate.
- *
- * The Gantt view's issue feed is bounded (≤1000 issues per project per
- * spec §Performance) so we filter on the client to keep the surface small
- * and avoid coupling to the global Tracker `filterStore` — which is wired
- * to the URL and to list-view bookkeeping that the Gantt does not share.
- *
- * The shape mirrors the spec's `DocumentQuery<Issue>` projection: a sparse
- * record where each present key is an array of allowed values, joined with
- * AND across keys, OR within a key. Empty arrays are ignored, so the UI
- * can write the same `{ status: [] }` shape it would use for a populated
- * filter without an explicit clear step.
- *
- * Forward-compat: unknown keys are ignored. Adding a new dimension is a
- * pure additive change — no migration needed.

 markers from inline comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Strips internal-tracking phrases from source-code comments (Tier-N Item M,
Tier-N #M, v121.NN, per Tier-N spec, leftover internal review markers).
Comments themselves are preserved — only the attribution labels are dropped.

Subject: [PATCH 285/388] feat(tracker): Predecessors column in Tracker list
 view

Adds an opt-in 'Predecessors' column to the Tracker issue list, so
power users can see dependency relationships without switching to the
Gantt view. Spec
docs/superpowers/specs/2026-05-14-huly-gantt-predecessor-column-design.md.

Rendering (spec-mandated):
- Identifier + Kind + Lag notation, e.g. 'PROJ-3 FS+2d'.
- Zero lag drops the +0d suffix ('PROJ-3 FS').
- Multiple predecessors collapse to 'first +N more' with a hover
  tooltip listing every upstream issue.
- Click on the identifier navigates to the predecessor issue via
  DocNavLink -> EditIssue (standard Tracker navigation).
- Empty cell when the issue has no incoming relations.

Files:
- plugins/tracker-resources/src/components/issues/
    PredecessorsColumnPresenter.svelte  -- live-query relation + sources
    PredecessorsTooltip.svelte           -- +N more hover body
- plugins/tracker-resources/src/plugin.ts  -- PredecessorsColumn component id
- plugins/tracker-resources/src/index.ts   -- register component
- models/tracker/src/viewlets.ts           -- column entry (optional, hidden by default)

i18n strings 'Predecessors'/'Vorgaenger' already exist in en+de from
the Gantt sidebar column work, no new strings needed.

Tests: 518 -> 531 (13 helper tests added in previous commit).
svelte-check: 0 errors on new components.

Subject: [PATCH 290/388] feat(tracker-resources): Visual DependencyEditor with
 2x2 mini-diagram picker

Replaces the dropdown in DependencyEditor with a 2x2 grid of clickable
SVG mini-diagrams (FS / SS / FF / SF). After a pick the grid collapses
to a compact single-diagram view plus an inline -14..+14d lag slider
and a 'Change type' link that re-expands the grid. The existing
NumberInput stays as fallback for values outside the slider range
(-30..+90 storage clamp unchanged).

Per spec 2026-05-14-huly-gantt-visual-dependency-editor-design.md:
- 2x2 layout (FS/SS top, FF/SF bottom)
- lag slider embedded in the picked diagram view
- collapse-after-pick UX with re-expand button
- role=radio + arrow-key keyboard navigation between diagrams
- aria-label + title tooltips with full kind-hint i18n strings

Subject: [PATCH 292/388] feat(tracker-resources): add diagram-helpers for
 Visual DependencyEditor

Adds pure-TS helpers for the upcoming 2x2-grid mini-diagram picker:

- DIAGRAM_KINDS in spec-mandated grid order (FS/SS/FF/SF)
- diagramGridIndex() for keyboard navigation (Arrow keys)
- clampLagSlider() for the inline -14..+14d slider
- getDiagramSvgPaths() returns rects + arrow polyline per kind,
  with FS/FF distinguishable by arrow endpoint (left vs right of S)

18 new tests, 549 total.

Subject: [PATCH 293/388] fix(tracker-resources): touch-action: none on bars +
 drawer header offset
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two small follow-ups discovered during the final pass:

  - GanttBar .bar gets touch-action: none so iOS Safari does not
    hijack pointerdown on a bar with native pan-zoom (Spec §"iOS-
    Safari Edge-Cases"). Without this the long-press timer never
    fires because Safari steals the gesture before pointerup.

  - The drawer's top offset was hardcoded to 32 px via a non-existent
    --gantt-header-height variable. HEADER_HEIGHT is 56 in
    GanttView.svelte; the drawer now matches, with a comment to keep
    it in sync. height: calc(100% - 56px) so the drawer doesn't
    overflow under the bottom of the canvas-cell either.

Tests: 631 / 631. svelte-check: 0 errors.

Subject: [PATCH 294/388] feat(tracker-resources): mobile drawer + responsive
 confirm popup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Phone-mode (≤640 px) gets:
  - Hamburger button in the toolbar that toggles a slide-out drawer
    overlay carrying the issue list (Spec §"Phone": Sidebar Phone =
    Slide-out-Drawer auf Tap).
  - Sidebar-cell goes absolute + translateX(-100%) by default; the
    .drawer-open class slides it to 0. Tap-anywhere-on-canvas
    backdrop dismisses it; the onJump handler also closes it once
    the user has scrolled to the picked row (Spec §"Phone": Tap
    schließt Drawer).
  - Resize-corner / resize-cell are hidden — finger-width column
    resize is fiddly and the drawer covers the viewport anyway.

Tablet-mode (641–1024 px) gets:
  - .nav-btn / .gantt-toolbar-icon-btn / .zoom-btn min-44x44 px hit
    targets so touch-tap is reliable (Spec §"Tablet": Hit-Targets
    min 44x44 px).

Confirm popups become responsive (Spec §"Risks": 600 px popups
overflow 320 px screens): max-width: min(480px, 95vw) + box-sizing
border-box. On Phone the popup is read-only so this is belt-and-
braces, but the cap also helps narrow-window desktop users.

i18n strings (EN + DE) added for hamburger aria-label and the
read-only hint. Tests: 631 / 631. svelte-check: 0 errors.

Subject: [PATCH 295/388] test(tracker-resources): cover three
 previously-untested gantt lib files

Close the coverage gap surfaced by the 2026-05-15 regression audit:

- cascade-token.ts: 9 tests covering default + custom prefix, the
  <date>-<counter> suffix shape, monotonic counter increment and 1000-call
  uniqueness.
- dependency-shift-send.ts: 5 tests around early-return paths (empty
  primaries+shifts, empty bundle, missing PersonSpace) and the onError /
  silent-swallow contract. The Tx-create bundle remains untested by
  design (pure IO glue with no behaviour to assert).
- menu-actions.ts: 14 tests covering the ganttExtraActions array shape
  (group, icon, component, props) plus the openSetStartDate popup wiring
  and the four callback branches (dismiss, clear, auto-fill-due,
  no-auto-fill).

exporter.ts stays untested: every export is bound to the DOM / canvas /
html2canvas / jsPDF and cannot run under the node Jest env without
either refactoring or pulling in jsdom. Audit report appended with the
rationale.

645 -> 673 tests.

Subject: [PATCH 296/388] chore(tracker-resources): scrub internal tier/version
 markers from inline comments
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Strips internal-tracking phrases from source-code comments (Tier-N Item M,
Tier-N #M, v121.NN, per Tier-N spec, leftover internal review markers).
Comments themselves are preserved — only the attribution labels are dropped.

Subject: [PATCH 297/388] feat(tracker-resources): hoist gantt toolbar into
 SpaceHeader row 2

Lift the gantt-toolbar controls (Group-by, Date-Nav, Zoom preset + days
input, Undo/Redo, Hamburger, Fullscreen) out of GanttView and into the
SpaceHeader's row 2 so the user sees a single unified toolbar instead
of three stacked strips.

Render order matches the spec: Filter -> Group-by -> Lupe -> Date-Nav ->
Week -> days -> Undo/Redo -> All/Active/Backlog -> Hamburger ->
Fullscreen (Hamburger now before Fullscreen, swapped from legacy).

State bridges across the parent/child boundary via a writable Svelte
store (ganttToolbarSnapshot): GanttView keeps owning the values and
handlers, writes a snapshot on every reactive update, and clears it
on destroy. A standalone GanttToolbarBar component subscribes to the
store and renders the controls in two clusters, one per slot.

SpaceHeader gains:
- overrideSearch prop + search slot to let consumers replace the
  built-in SearchInput + FilterButton when needed
- extra-trailing slot rendered after the ModeSelector

Non-gantt viewlets (List, Kanban) keep the SpaceHeader default exactly
as before.

+  Lifted Gantt toolbar. The controls render in IssuesView's SpaceHeader
+  row 2 via slot overrides; their state lives in GanttView and is
+  bridged here via `ganttToolbarSnapshot`. Two render sections share one
+  component so the markup stays DRY:

+                         (mounted between Filter-button and Lupe)
+    section="trailing" → Hamburger + Fullscreen
+                         (mounted after the All/Active/Backlog ModeSelector)

From 2fd2ee5beb96b70263fa814bad5087c84a7fbcaa Mon Sep 17 00:00:00 2001

Subject: [PATCH 298/388] fix(tracker-resources): correct visual order of
 merged gantt toolbar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The SpaceHeader's row-2 search cluster uses flex-direction: row-reverse,
so markup order is reversed from visual L→R. Split GanttToolbarBar's
search section into search-mid (Group-by only) and search-end (the rest)
and reverse the internal markup order so the user sees:

  Filter → Group-by → Lupe → Date-Nav → Week → days → Undo/Redo

The extra cluster keeps row direction so the trailing section's
Hamburger-before-Fullscreen markup matches the visual order.

   Lifted Gantt toolbar. The controls render in IssuesView's SpaceHeader

-                         (mounted between Filter-button and Lupe)

Subject: [PATCH 299/388] feat: global Fullscreen toggle + Lupe-first toolbar +
 milestone labels in extended sidebar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Move the Fullscreen toggle out of the gantt-toolbar trailing slot into
  the global status bar (packages/ui Root.svelte, next to the gear icon)
  so it's reachable from every viewlet, not only Gantt. The button
  switches Maximize/Minimize icon based on document.fullscreenState.

- Swap the search-row ordering so the Lupe (SearchInput) sits leftmost
  and Filter sits next to it: visual L→R is now Lupe → Filter →
  Group-by → Date-Nav → Week → days → Undo/Redo.

- Restore milestone labels (and start/due dates) in the extended-columns
  sidebar. The Phase-3a renderer fell through to an empty placeholder
  for any non-issue row; the user reported milestone text vanished as
  soon as Extended Sidebar Columns was enabled. Now the title column
  shows the milestone label (italic, matching the legacy compact
  sidebar), and the startDate/dueDate/deadline columns show the
  milestone's startDate/targetDate.

Subject: [PATCH 303/388] fix(gantt): bump contrast on Todo + Cancelled status
 bars

Todo previously used state-primary-background-color (designed for chips,
too pale for full bar surfaces) with caption-color text. Replaced with
the saturated state-primary-color + white contrast text, matching the
visual weight of InProgress / Done.

Cancelled keeps its pale fill (preserves the 'subdued' semantic) but
the bar stroke widens from 1px to 2px so the silhouette stays
readable. The condition is combined with the existing critical/violated
stroke-width logic so critical highlighting still takes priority.

Spec section G.

Subject: [PATCH 304/388] feat(gantt): add GanttBarIssueLike type +
 isPastDue/isBlocked predicates

Lays down the GanttBarIssueLike interface in bar-colors.ts (type-only;
the resolver body is appended in a follow-up commit) so both predicates
and the resolver share one canonical shape. All fields except title /
startDate / dueDate are optional so synthetic milestone-summary bars
from GanttCanvas.svelte:299 satisfy the interface directly.

Two pure predicates in bar-overlays.ts:

  isPastDue(issue, statusCategoryFor, now)
    True iff dueDate < now AND status category !== Won. Returns false
    when status is undefined (synthetic milestone bars) so old
    milestones are not flagged as past-due issues.

  isBlocked(issue, predecessorIds, predStatusOf, statusCategoryFor)
    True iff at least one FS predecessor has known status != Won.
    Map keys are stringified Refs throughout to avoid symbol-identity
    flakiness across Svelte rerenders.

isPastDue is intentionally named differently from the existing
deadline-marker.ts:22 isOverdue() which has different semantics
(dueDate > deadline). User-facing label stays 'Overdue'.

Spec section C. 10/10 unit tests passing.

Subject: [PATCH 305/388] feat(tracker): add optional color field to Component
 and Milestone
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds an optional 'color: number' (PaletteColorIndexes-based) to both
the Component and Milestone interfaces in plugins/tracker, with the
matching @Prop(TypeNumber()) decorator on TComponent / TMilestone in
models/tracker so the server side persists the field on writes.

Optional + no migration — existing records (color === undefined) will
render through a deterministic hash-from-id fallback in the Gantt
color resolver (Task 5).

i18n key tracker.string.Color added in en + de via tracker-assets/lang.

Subject: [PATCH 306/388] feat(tracker-resources): ColorsPopup swatch in
 EditComponent + EditMilestone

Lets the user pick a palette color for each Component / Milestone via
the lightweight ColorsPopup component from @hcengineering/view-resources
(dispatches 'close' with the picked palette index). Records with
color === undefined render with a deterministic hash-from-id fallback
so the swatch is always non-empty.

Picker pattern is the standalone-ColorsPopup pattern, distinct from
CreateProject's combined IconPicker.

Subject: [PATCH 307/388] feat(gantt): add pure bar-color resolver for 6 color
 modes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Extends bar-colors.ts (which already contained the GanttBarIssueLike
type from Task 2) with the actual resolver function. Returns either a
CSS-var fill/border/text triple OR a paletteIndex that callers resolve
via getPlatformColor(idx, dark).

All model lookups are injected via BarColorContext — file has zero
platform imports beyond the IssuePriority enum + PaletteColorIndexes
constants.

Priority palette mirrors the existing IssuePriorityColor map in
tracker-resources/src/utils.ts:593 — Urgent=Orange, High=Sunshine,
Medium=Ocean, Low=Cloud, NoPriority=Blueberry.

Synthetic milestone-summary bars (no status / priority) get the
NEUTRAL triple in every mode that depends on those fields. Tests
cover the 6 modes plus the synthetic-bar regression case.

Also adds moduleNameMapper to jest.config.js so tests importing
@hcengineering/ui for pure constants (PaletteColorIndexes) work
without pulling in the svelte/store transitive dependency. Tests
that need richer stubs continue to override via jest.mock().

Spec section A.

Subject: [PATCH 308/388] feat(gantt): extend GanttSavedViewOptions with 4 new
 toolbar fields

Adds ganttBarColorBy + three boolean overlay/progress toggles to the
(de)serializer shape so saved Gantt views can persist the new
bar-coloring toolbar state. Validators reject unknown enum values;
missing fields stay undefined so existing saved views remain readable
without migration. The Apply side handles missing keys via active-
default reset (Task 11).

mergeGanttSavedView keeps its (base, opts) signature; the body now
also writes the four new fields when present.

Spec section F.

Subject: [PATCH 309/388] feat(gantt): wire bar-color resolver into GanttView +
 GanttBar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replaces inline statusFill() in GanttBar with delegation to
resolveBarColors(). The mode + overlays + progress-fill flags live as
Svelte writable stores at GanttView level, passed down via Svelte
context (setContext called once, .set() to update).

A project-scoped BarColorContext is built per render frame from
statusCategoryMap (already at GanttView line 1106), componentsById
(new derivation), milestonesById (existing at line 884). Top-8
assignee classification computed from current issues.

GanttBar's narrow {title,startDate,dueDate} prop is widened to
GanttBarIssueLike — most call sites already pass the full Issue, and
the synthetic milestone-summary bar at GanttCanvas.svelte:299 already
satisfies the optional-fields shape without changes.

ganttToolbarSnapshot setter gains ganttBarColorBy +
onColorBySelectChange, ready for the toolbar dropdown (Task 10).

Spec sections A + F.

Subject: [PATCH 310/388] feat(gantt): render Past-due stripe + Blocked hatch
 overlays

Two new SVG layers inside the bar <g>, independent of the color-by
mode, so they layer cleanly onto status / priority / assignee /
component / milestone fills.

Past-due: 3px red left-edge stripe when isPastDue() returns true
(dueDate < now && status category !== Won; synthetic milestone bars
without status return false).

Blocked: diagonal hatch (15% opacity) when at least one FS
predecessor has known non-Won status. Predecessor map is built once
from the existing relations: IssueRelation[] array in GanttView and
threaded into GanttBar via Svelte context (gantt-predecessors-by-issue,
gantt-pred-status-by-issue). Map keys are stringified Refs to avoid
symbol-identity flakiness across Svelte rerenders.

Both layers use pointer-events: none so drag/click still route to
the bar itself. The blocked-hatch uses x/w/barY/barH (existing
coords in scope inside the bar <g>).

Spec section C.

Subject: [PATCH 311/388] feat(gantt): sub-issue progress fill (Status-mode
 only)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When 'Show sub-issue progress' is enabled, GanttView fires a parallel
global query for child issues by attachedTo, independent of the active
filter chain. Each parent bar renders a darker inner overlay covering
done/total of its bar width. Done = status category Won.

Scope is intentionally global (numerator AND denominator) per spec
section D — 'progress of this issue' is a property of the issue, not
of the current filter.

Disabled on summary bars (group-headers) to avoid double-counting.
Disabled in non-Status color modes where the inner overlay would be
visually ambiguous against a categorical fill.

progressFraction is pure — takes (issue, subs, statusCategoryFor) and
returns null when there is no data to compute from. 5/5 unit tests
cover the boundary cases.

Spec section D.

Subject: [PATCH 312/388] feat(gantt): toolbar Color-by dropdown with 6 modes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a Color-by <select> directly next to Group-by in the Gantt
toolbar's 'search-mid' section. One click switches the bar-fill mode
across Status / Priority / Assignee / Component / Milestone / None.
Wires through the ganttToolbarSnapshot store
(snap.ganttBarColorBy + snap.onColorBySelectChange — both added in
Task 7's snapshot extension).

i18n keys for all six labels in en + de via tracker-assets/lang.

Spec section B.

Subject: [PATCH 313/388] feat(gantt): persist bar-color toolbar state in saved
 views
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Wires the four new view-option fields (ganttBarColorBy plus the three
overlay/progress toggles) through all three saved-view code paths:

- Save: buildSavedViewOptions() now includes all four fields in the
  payload that goes through mergeGanttSavedView() (T6 extended the
  merge body to write them out).
- Apply: the existing applyGanttSavedView() (line 493) is extended
  with active-default resets for the four new stores — when the
  loaded blob is missing a field, the store snaps back to its spec
  default (Status / on / on / off) instead of retaining the
  previous saved-view's value (prevents state leak across view
  switches).
- Modified-check: isCurrentGanttViewModified() compares the four
  fields against the saved snapshot so the 'modified' indicator
  reflects toolbar changes too, not just zoom changes.

Spec section F.

Subject: [PATCH 314/388] feat(gantt): expose overlay + progress toggles in
 ganttViewOptions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds three new entries to the declarative ganttViewOptions() model so
the standard Customize-View popover (cog icon) renders the toggles
automatically — no separate Svelte popup component to maintain.
Pattern matches existing ganttCriticalPath / ganttConfirmMove entries.

GanttView.svelte reads the resulting view-options blob into the same
writable stores the toolbar dropdown also writes to, so the toggle
state stays in sync regardless of which UI surface flipped it.
Unconditional .set() with default fallback prevents state leak across
view switches.

Spec sections C + D.

Subject: [PATCH 315/388] fix(gantt): lighten canvas background

The default --theme-bg-color (#F1F1F4 in light theme) reads as
distinctly gray against Huly's white panels and toolbars. Switch the
canvas background to --theme-comp-header-color (#FBFBFC in light /
#1E2024 in dark) so the Gantt canvas reads as a workspace surface
that contrasts subtly with the surrounding chrome instead of looking
like an off-color block.

User feedback 2026-05-20.

Subject: [PATCH 316/388] fix(fulltext): bump model version to 0.7.423 to match
 deployed workspaces
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The fulltext-pod's compiled model version (baked into bundle/model.json via
common/scripts/version.txt at build time) was 0.7.422 while the deployed
workspace pods had been migrated to 0.7.423. The fulltext-pod rejected every
incoming Tx with a 'wrong version' warning, so newer issues — including the
user-reported OSKOS-51 'Telescopic loader' — were never indexed and search
returned empty results.

Bumping version.txt aligns the compiled model with the workspaces. All future
builds (front, transactor, workspace, tool, fulltext) will emit 0.7.423.

Adds plugins/view-resources/src/__tests__/README-search-rootcause.md as the
regression marker — pure-TS tests cannot exercise the ES round-trip, so the
README points future PRs to the live verification in the Task 6 Playwright
case.

Co-finding during the investigation: huly_v7-redpanda-1 had exited the same
morning, causing fulltext-pod to lose its queue consumer for ~3h. Restarting
redpanda + the new fulltext image cleared both issues. The redpanda restart
is operational, not in this commit.

+# Search Root-Cause Regression — 2026-05-17
+
+The 2026-05-17 title-search bug (typing `loader` against `OSKOS-51 Telescopic
+loader — delivery & install` returned 0 results) was a server-side
+indexing/version-skew issue. It cannot be reliably regression-tested in Jest —
+a pure-TS test cannot exercise the Elasticsearch round-trip.
+
+## Root cause (recorded for future PRs)
+
+- `common/scripts/version.txt` was at `0.7.422`. The local deployment had
+  forced workspace migrations to `MODEL_VERSION=0.7.423` via compose env, so
+  the workspaces' persisted `core:class:Version` document was on `0.7.423`.
+- The fulltext-pod, built from this codebase, embedded model version `0.7.422`
+  into `pods/fulltext/bundle/model.json` at build time.
+- Every Tx coming from a `0.7.423` workspace was dropped by the fulltext-pod
+  with a `wrong version` warning, so new issues were never indexed and search
+  returned empty results for them.
+
+Companion issue spotted during the investigation: `huly_v7-redpanda-1` had
+exited at 07:06 UTC on the same day, leaving the fulltext-pod unable to
+consume from the queue at all for ~3h. Restarting it cleared the queue
+backlog.
+
+## How to re-verify before merging any PR that touches:
+
+- `foundations/server/packages/elastic/src/adapter.ts`
+- `pods/fulltext/**`
+- `models/server-tracker/**`
+- `plugins/view-resources/src/components/filter/**`
+- The SearchInput / SearchInputAdvanced wire-contract
+- `common/scripts/version.txt`
+
+Run the live verification described in
+`docs/superpowers/plans/2026-05-17-tracker-search-rootcause-fix.md` Task 6:
+typing `loader` in the Tracker Lupe must return `OSKOS-51` within 500 ms in
+the gamedesigndemov3 workspace's Ostrowo Kościelne project.
+
+ES-level direct verification (`docker exec huly_v7-elastic-1 curl -s -X POST
+"localhost:9200/huly_storage_index_v2/_search" -H "Content-Type:
+application/json" -d '{"query":{"multi_match":{"query":"loader","fields":[
+"searchTitle","fulltextSummary","identifier"]}}}'`) must return ≥1 hit
+identified as `OSKOS-51` in the affected workspace.
+
+## Future-prevention
+
+A version-skew detector in the deploy pipeline should refuse to publish a pod
+image whose compiled `model.json` patch differs from the workspace's stored
+patch by more than 0. Tracked separately; out of scope for this PR.

Subject: [PATCH 317/388] feat(ui+gantt): rightmost fullscreen +
 jump-to-start/end icons + max-zoom-out limit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three small UX improvements consolidated into one commit so Plan 2's commits
stay focused on the filter/search redesign:

1. Global Fullscreen toggle in the topmost status bar (Root.svelte) is now
   the rightmost icon — sits past the gear/Settings, not between Clock and
   Settings. Markup reordered: Fullscreen first, then Settings, then Clock
   in the row-reverse flex container so visual L→R ends with Fullscreen.
   GanttToolbarBar's trailing-cluster Fullscreen affordance is removed in
   the same change (global one supersedes it).

2. New JumpToStart and JumpToEnd icons — visually a left/right arrow with
   a vertical bar pinned at the start/end (\|← and →\|). Replace the plain
   ArrowLeft/ArrowRight in the Gantt toolbar's date-nav cluster so the
   intent (skip to first/last) is unambiguous.

3. Maximum zoom-out floor in GanttView. Wheel-zoom, pinch-zoom and the
   visible-days numeric input all clamp to a dynamic minimum px/day that
   keeps bars at \u2265 90% of the canvas viewport. Computed as
   0.9 * canvasViewportWidth / barExtentDays. Without it the user could
   wheel out into an empty void where every issue collapses to a tiny
   centre island.

From 852d906ad8e7b20e6794a69a44ba94db2438b33d Mon Sep 17 00:00:00 2001
From: Michael Uray <michaeluray@users.noreply.github.com>
Date: Sun, 17 May 2026 11:17:48 +0000
Subject: [PATCH 320/388] refactor(gantt): drop duplicate corner-range
 date-nav, keep collapse/expand
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The sidebar's corner-cell previously rendered Collapse/Expand + [«] [date-
range text] [»]. The toolbar's date-nav cluster (← ◀ Today ▶ → + date-
picker) plus the new merged row 2 already cover every affordance the
inline strip provided, so the duplicate is removed.

Collapse/Expand stay leftmost in the corner-cell and now render even when
groupBy is a swimlane mode — but disabled (greyed, no-op click). Tooltip
explains via the new GanttCornerNoOpInSwimlane IntlString. Localized in
all 13 tracker-assets lang files (English fallback for the non-de
locales).

Subject: [PATCH 321/388] feat(ui): IModeSelector.disabled + relocate
 ModeSelector left of Filter

Three-layer plumb for the disabled state:
- IModeSelector gets two new optional fields (disabled, disabledReason).
- SwitcherBase forwards disabled to the radio input + paints the wrapper
  with a 0.4-opacity overlay + not-allowed cursor.
- Switcher propagates disabled to every SwitcherBase, plus a group-level
  tooltip that wins over per-item tooltips while disabled.
- ModeSelector reads props.disabled + props.disabledReason and threads
  them into the Switcher, plus blocks the on:select dispatch when
  disabled.

Wired into Tracker's IssuesView: Issues.svelte detects an active
Status-filter via $filterStore and sets modeSelectorProps.disabled +
disabledReason accordingly. The ModeSelector now also renders INLINE in
the Gantt-mode search slot (right after the FilterButton in markup
order, which puts it visually between Filter and Lupe in the
row-reverse cluster). The legacy SpaceHeader extra-slot render is
suppressed in Gantt mode by passing modeSelectorProps=undefined when
isGanttMode is true.

13 lang files updated with the new IntlString.

From e0f79d4c91af36784c531a47dd0e1b9d900b7629 Mon Sep 17 00:00:00 2001
From: Michael Uray <michaeluray@users.noreply.github.com>
Date: Sun, 17 May 2026 14:35:22 +0000
Subject: [PATCH 322/388] feat(tracker): customize-view toggles for
 ModeSelector + searchScope + highlight
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three new ViewOptions exposed in the Customize-View popup for every Issue
viewlet (List, Kanban, Gantt):

- showQuickModeSelector (toggle, default true) — hides the inline
  All/Active/Backlog ModeSelector when the user wants a more minimal
  toolbar. IssuesView gates the inline render on this toggle.
- searchScope (dropdown, default 'all') — three values: title /
  title-description / all. Drives the SearchInputAdvanced encoder in T6
  (this commit just registers the option; the encoder consumes it next).
- searchHighlight (toggle, default true) — turns the match highlighting
  in T9 on/off. T9 reads the same flag.

Added to both:
- issuesOptions() (shared by List + Kanban + the Issues 'allIssues'
  view).
- The Gantt-specific ViewOptionsModel block (it doesn't go through
  issuesOptions, but exposes its own 'other' array).

8 new IntlStrings (incl. the 2 from T3 + T4 backfilled for non-en/de
locales — they were originally added only to en+de). All 13 tracker-
assets lang files now carry every new key with English fallback.

Signed-off-by: Michael Uray <michaeluray@users.noreply.github.com>

Subject: [PATCH 323/388] feat(search): SearchInputAdvanced with
 prefix-operators + ES query_string branch

Client side:
- New `SearchInputAdvanced` component in packages/ui wraps SearchInput's
  visual style verbatim, accepts a `scope` prop, dispatches change with
  { raw, encoded } so consumers can keep the user-facing input pristine
  while routing the encoded wire-form to the server.
- New `encodeSearch` pure helper (encoder.ts + 9 jest tests). Aliases
  user-friendly prefixes (title:, id:, comments:) to actual ES fields
  (searchTitle, identifier, comments.message). Bare-term scope wrapping
  applies only when no prefix is present.
- Shared `rawSearchTextStore` + `resultIssueCountStore` declared in
  plugins/view-resources/src/stores.ts. The store lives in view-resources
  (the lower dependency layer) so tracker-resources can import without
  inverting the package-dependency graph. T8 + T9 read+write these stores.

Server side:
- foundations/server/packages/elastic/src/adapter.ts: when $search
  contains a `:` token (Lucene field:value syntax), route via
  `query_string` with per-field boosts (searchTitle^3, searchShortTitle^2,
  identifier^2, description.plain, comments.message^0.7, fulltextSummary).
  Without `:` the legacy `simple_query_string` path is preserved exactly
  so existing non-Tracker consumers are unaffected.

Tracker integration:
- IssuesView now keeps two parallel search states:
    - `search` (legacy, written by SpaceHeader's built-in input for
      List + Kanban)
    - `searchRaw` + `searchEncoded` (Gantt-mode slot override). The
      reactive `effectiveSearch` picks the right one and writes it
      into $search. `rawSearchTextStore` is fed from `searchRaw` so
      the upcoming T9 HighlightedText can read the user-typed form
      (not the encoded form).

+ * Two transformations applied:
+ *
+ * 1. **User-prefix → ES-field aliasing.** User-friendly shorthands map to
+ *    the actual indexed field names:
+ *      title:foo    → searchTitle:foo
+ *      id:foo       → identifier:foo
+ *      comments:foo → comments.message:foo
+ *    ES-native field names (searchTitle:, identifier:, description.plain:,
+ *    comments.message:) pass through verbatim — power users can use them
+ *    directly.
+ *
+ * 2. **Bare-term scope wrapping.** When the input contains no prefix at all
+ *    AND the Customize-View `searchScope` is restrictive, wrap the bare
+ *    terms in the field-scope:
+ *      scope=title             → searchTitle:(<bare>)
+ *      scope=title-description → (searchTitle:(<bare>) OR description.plain:(<bare>))
+ *      scope=all               → <bare> (untouched; the adapter falls back to
+ *                                simple_query_string across all indexed text)
+ *
+ * The two transformations are independent; an input that already contains
+ * a prefix is only aliased (transformation 1), never wrapped (transformation
+ * 2). This matches user intent — they specified a field explicitly.

Subject: [PATCH 324/388] feat(tracker): empty-state card for zero search
 results
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the user types a search term and zero matches come back, the empty
grid was previously confusing — was it filtered to empty, broken, or
still loading? Now we render a SearchEmptyState card on top with:
- 🔍 icon + 'No issues found for {query}' headline.
- Active-filter chips listed (so the user sees what's narrowing the
  result set).
- 'Suche ohne Filter' button: clears all filterStore entries, keeps
  the search text.
- 'In allen Projekten suchen' button: navigates to the All-Issues
  special view with the search text preserved.

Wiring:
- Pure shouldShowEmptyState() helper + 4 jest tests in
  tracker-resources/src/components/SearchEmptyState.helpers.ts.
- SearchEmptyState.svelte renders the card; mounted in IssuesView as an
  absolutely-positioned overlay on top of the ViewletContentView. The
  viewlet stays mounted (otherwise its onDestroy reset would loop with
  the empty-state's mount/unmount).
- Each viewlet writes its result-count into the shared
  resultIssueCountStore (declared in T6, view-resources/stores.ts) and
  resets to -1 on destroy:
    - view-resources/list/List.svelte writes `docs.length`.
    - tracker-resources/KanbanView.svelte writes `tasks.length`.
    - tracker-resources/gantt/GanttView.svelte writes
      `issues.length + milestones.length`.

4 new IntlStrings (SearchEmpty{Title,ActiveFilters,ClearFilters,
AllProjects}) in all 13 tracker-assets lang files with English/German
canonical translations.

Subject: [PATCH 325/388] feat(tracker): match-highlight in list + gantt
 sidebar titles
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the user has typed something in the Lupe, the matching substring
inside Issue identifiers + Gantt-sidebar titles is now wrapped in a
<mark> for visual scanning.

- New HighlightedText component in packages/ui (Svelte 4) takes
  { text, query } and renders alternating <mark>/text spans. Reads the
  RAW user text from rawSearchTextStore (NOT the encoded $search wire-
  form) — see helpers comment for the graceful fallback if an encoded
  string ever slips through.
- splitHighlightSegments() pure helper with 7 jest tests including the
  documented v1 limitation: only the leading user-prefix (title:, id:,
  comments:) is stripped, multi-prefix queries fall back to no-match.
- IssuePresenter wraps issue.identifier in HighlightedText so 'id:OSKOS-'
  searches highlight the prefix.
- GanttSidebarColumn wraps issue.title in HighlightedText for the title
  column (extended-sidebar mode).

Subject: [PATCH 326/388] fix(tracker): drop .issuesview-content wrapper that
 broke Gantt initial-render height
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The flex wrapper around ViewletContentView gave the viewlet area no
defined height in the parent layout context, so GanttView (height:100%)
collapsed on first paint. Filter toggle reflowed and patched it. Render
SearchEmptyState as a top-level sibling instead — when it shows the
viewlet is empty anyway, so no overlay tricks are needed.

Subject: [PATCH 327/388] fix(filter): InlineFilterChips chip-render and
 live-verification follow-ups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bundled set of fixes that surfaced during live-deploy verification of the
InlineFilterChips feature commit (8638208cb). Squashed together here as a
single follow-up commit so the public history reflects the user-visible
delta rather than a debugging trail.

Issues addressed:

- The "+ Add filter" affordance is preserved when filters are active.
  Previously the FilterButton flipped to "Clear filters" once any filter
  was added, leaving no UI path to add a second filter. Clear-all now
  lives on InlineFilterChips as a trailing ghost button.

- InlineFilterChips is mounted in List / Kanban as well as Gantt mode.
  The filter→resultQuery reactive path was originally Gantt-only.

- visibleCount is seeded to filterStore.length on each store mutation so
  the first paint renders every chip (otherwise chipEls.widths is [] and
  visibleCount stays at 0 → chips invisible).

- recompute() skips while containerWidth=0 (ResizeObserver hasn't fired
  yet on first paint) and resets hiddenCount on every filterStore change
  to avoid stale +N badges.

- Chip cluster has a max-width: 22rem cap. Without it, the cluster grew
  to its content's natural width and pushed Group-by / date-nav / zoom /
  undo-redo / hamburger / fullscreen off the viewport edge.

- Measured chip widths are cached by filter.index, not by array slot.
  Unmounted chips report width=0 from getBoundingClientRect, which would
  feed back into computeOverflow as "everything fits" → chips re-expand
  → ResizeObserver fires on the new container → loop. Per-index caching
  breaks the oscillation.

- The +N badge is a solid pill (using --theme-state-attention-color) and
  the overflow popover uses --theme-popup-color + --theme-popup-shadow +
  backdrop-filter blur so the Gantt week headers and grid lines no
  longer bleed through. HiddenFilters IntlString added for all 13
  supported locales (en, de, es, fr, it, pt, pt-br, ru, cs, tr, ja, ko, zh).

Subject: [PATCH 328/388] fix(tracker): address code-review blockers + Codex
 follow-ups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Blockers from the independent review (HOLD verdict):

C1 — Restore FilterBar chip render for the 17 non-Tracker consumers
(lead/contact/drive/recruit/training/controlled-documents/workbench/
chunter/task plus Tracker's MilestoneBrowser/ComponentBrowser/
IssueTemplatesView). Add hideChips:boolean prop that IssuesView sets
true; everyone else keeps the legacy chip strip. Move the
makeFilterQuery data path back into FilterBar (debounced via
reduceCalls) and turn InlineFilterChips into a presentational-only
component so the dispatch never doubles.

C2 — Strip local-deployment fixtures from shipped files. Delete
plugins/view-resources/src/__tests__/README-search-rootcause.md
(internal investigation pointer; the full report lives in
docs/test-reports/). Rename OSKOS- → HULY- in tests and in the
elastic adapter doc-comment.

C3 + Codex#1 — Wire SearchInputAdvanced for every Tracker viewlet,
not just Gantt. The slot override now runs for List/Kanban too, so
prefix operators (title:/id:/comments:), searchScope, the empty-state
card, and the rawSearchTextStore-driven match highlight all work
uniformly.

Codex#2 — Empty-state is now rendered INSTEAD of ViewletContentView
when shouldShowEmptyState() is true, not below it. List/Kanban/Gantt
delay the resultIssueCount store write until their first LiveQuery
response, so the empty-state card no longer flashes during initial
load before the query has resolved.

Codex M1 — SearchInputAdvanced gains a Clear (×) button parallel to
SearchInput.svelte:87, plus Escape-to-clear keybinding. Drop the dead
`value = _search` line that confused the one-way binding contract.

Codex M2 — SwitcherBase disabled keeps pointer-events so the
disabled-reason tooltip stays reachable on hover; only the underlying
<input type=radio disabled> blocks selection.

ES query_string + encoder — Restrict field-targeted routing to the
known field names. Stray colons (URLs, times, `POC: review`) no
longer trip the parser and silently return zero hits.

Plus assorted polish:
- I3: ModeSelector resets to 'all' on the rising edge of
  hasStatusFilter (Spec §7.4).
- I4/I5: InlineFilterChips caches widths by filter.index instead of
  by array slot, so add/remove cycles don't trash the cache.
- N1: DE 'Title' → 'Titel' / 'Description' → 'Beschreibung' /
  'Comments' → 'Kommentare' in the SearchScope labels.
- N2: ko.json reformatted back to upstream's 4-space indentation.
- N4: viewlets.ts extracts SEARCH_VIEW_OPTIONS to a single const so
  the List/Kanban and Gantt blocks can't drift.
- N6: gotoAllIssues() guards against non-tracker routes.
- N8: cloneQuery prefers structuredClone when available.
- N9: HighlightedText accepts an enabled prop; IssuesView mirrors
  viewOptions.searchHighlight into a store so the toggle works.
- O5: aria-label/aria-haspopup/aria-expanded on the +N badge, role +
  aria-hidden on SearchEmptyState's icon, <h2> for the title.
- +N badge moved from --theme-state-negative-color (reserved for
  destructive) to --theme-state-attention-color.

-# Search Root-Cause Regression — 2026-05-17
-
-The 2026-05-17 title-search bug (typing `loader` against `OSKOS-51 Telescopic
-loader — delivery & install` returned 0 results) was a server-side
-indexing/version-skew issue. It cannot be reliably regression-tested in Jest —
-a pure-TS test cannot exercise the Elasticsearch round-trip.
-
-## Root cause (recorded for future PRs)
-
-- `common/scripts/version.txt` was at `0.7.422`. The local deployment had
-  forced workspace migrations to `MODEL_VERSION=0.7.423` via compose env, so
-  the workspaces' persisted `core:class:Version` document was on `0.7.423`.
-- The fulltext-pod, built from this codebase, embedded model version `0.7.422`
-  into `pods/fulltext/bundle/model.json` at build time.
-- Every Tx coming from a `0.7.423` workspace was dropped by the fulltext-pod
-  with a `wrong version` warning, so new issues were never indexed and search
-  returned empty results for them.
-
-Companion issue spotted during the investigation: `huly_v7-redpanda-1` had
-exited at 07:06 UTC on the same day, leaving the fulltext-pod unable to
-consume from the queue at all for ~3h. Restarting it cleared the queue
-backlog.
-
-## How to re-verify before merging any PR that touches:
-
-- `foundations/server/packages/elastic/src/adapter.ts`
-- `pods/fulltext/**`
-- `models/server-tracker/**`
-- `plugins/view-resources/src/components/filter/**`
-- The SearchInput / SearchInputAdvanced wire-contract
-- `common/scripts/version.txt`
-
-Run the live verification described in
-`docs/superpowers/plans/2026-05-17-tracker-search-rootcause-fix.md` Task 6:
-typing `loader` in the Tracker Lupe must return `OSKOS-51` within 500 ms in
-the gamedesigndemov3 workspace's Ostrowo Kościelne project.
-
-ES-level direct verification (`docker exec huly_v7-elastic-1 curl -s -X POST
-"localhost:9200/huly_storage_index_v2/_search" -H "Content-Type:
-application/json" -d '{"query":{"multi_match":{"query":"loader","fields":[
-"searchTitle","fulltextSummary","identifier"]}}}'`) must return ≥1 hit
-identified as `OSKOS-51` in the affected workspace.
-
-## Future-prevention
-
-A version-skew detector in the deploy pipeline should refuse to publish a pod
-image whose compiled `model.json` patch differs from the workspace's stored
-patch by more than 0. Tracked separately; out of scope for this PR.

Subject: [PATCH 329/388] fix(gantt): compact Group-by + Color-by toolbar
 dropdowns
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

User feedback: the two dropdowns took too much horizontal space in
the unified toolbar row, especially once filter chips are also
present (mode-selector + Lupe + Add-filter + chips + Clear-filters
+ Group-by + Color-by would overflow on narrower viewports).

Changes:
- Drop the visible 'Group by' / 'Color by' Label inside each wrap.
  The intent moves to the tooltip on the wrap itself, which Huly
  surfaces on hover the same way other icon-only toolbar elements
  work.
- Add a tiny text glyph prefix per dropdown so the two stay visually
  distinguishable when adjacent: ▤ for Group-by (grid/bands metaphor),
  ● for Color-by (filled swatch metaphor). Glyphs sit at 55% opacity
  so they read as decoration, not action targets.
- Tighten padding 0.5rem → 0.375rem left / 0.25rem right and gap
  0.375rem → 0.125rem.
- Replace the native <select> chevron with a CSS-drawn one of the same
  visual weight as the rest of the toolbar's icons (appearance: none
  + linear-gradient triangle).
- Add aria-label fallbacks pointing to the existing i18n string so
  screen-readers still announce 'Group by' / 'Color by' as the
  control name.

Net effect: each dropdown shrinks roughly 50px in width without
losing functionality or accessibility.

Subject: [PATCH 330/388] fix(gantt): shorten GanttColorByNone + cap select
 intrinsic width
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Native <select> sizes itself to the longest option's text width, so a
verbose label like 'Uniform (no color coding)' was forcing the
Color-by dropdown to ~175px even after dropping the visible 'Color by'
label.

Two complementary fixes:
- Shorten GanttColorByNone (en: 'Uniform', de: 'Einheitlich') — drops
  the parenthetical that was meant as a hint but functioned as bloat.
  Tooltip 'Color by' on the wrap already disambiguates.
- Add max-width: 8rem + text-overflow: ellipsis to both select rules
  so any future long label can't blow up the toolbar.

Subject: [PATCH 331/388] fix(tracker+ui+gantt): three Codex Round-5 findings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

F1 (High): IssuesView search-state leaked across route/space switches.
  The local searchRaw was reset to '' on mount, but the shared
  rawSearchTextStore was only written from onSearchChange(). A new
  view therefore mounted with an empty input field while the global
  store still held the PREVIOUS view's text — match-highlight and
  Empty-State could trigger on a stale query the user never typed.

  Fix in plugins/tracker-resources/src/components/issues/IssuesView.svelte:
  reactive '$: rawSearchTextStore.set(searchRaw)' so the store mirrors
  the LOCAL searchRaw on every change (including mount-to-empty), and
  onDestroy() clears the store so route-out cannot leak either.

F2 (High): Prefix-targeted search (title:C++, comments:foo/bar) blew up
  in Elasticsearch query_string parser. The encoder returned aliased
  prefix terms RAW without escaping Lucene-reserved chars, so values
  containing '+', '!', parens, brackets, etc. produced parse errors
  surfacing as zero hits.

  Fix in packages/ui/src/components/SearchInputAdvanced.encoder.ts:
  new escapePrefixValues() runs a single regex over the aliased
  string, matching '<es-field>:<value>' clauses with three value
  shapes (paren-wrapped / quoted / bare). For bare values we wrap +
  escape ONLY when reserved chars are present (preserves the readable
  'searchTitle:loader' wire string for the common case), quoted values
  pass through as ES phrase literals, paren-wrapped values get their
  inner content escaped. Whitespace and boolean operators (AND/OR/NOT)
  between clauses pass through verbatim.

  Reserved-char set is narrower than escapeForQueryString — excludes
  '-' (ES tolerates mid-term), '*'/'?' (legitimate wildcards), and ':'
  (cannot appear in a value at this stage by construction).

F3 (Medium): Reloading the active Saved Gantt View after local edits
  was a no-op. The Apply '$:' block at GanttView.svelte:596 short-circuits
  when lastAppliedSavedViewId equals the loaded view's _id — desired
  behaviour for stale selectedFilterStore traffic from other viewlets,
  but broken when the user EXPLICITLY re-selected the same view in the
  Load dialog to REVERT their dirty state.

  Fix in plugins/tracker-resources/src/components/gantt/GanttView.svelte:
  the load-dialog click handler now resets lastAppliedSavedViewId = null
  BEFORE selectedFilterStore.set(next), so the guard sees a fresh state
  and applies the loaded view's options.

Tests:
- 4 new cases in packages/ui/src/components/SearchInputAdvanced.test.ts:
  - Reserved-char wrapping (C++ → C\+\+, foo/bar → foo\/bar)
  - Clean values stay bare (title:loader → searchTitle:loader)
  - Quoted phrases pass through
  - Boolean operators between prefix clauses preserved
  - User-typed parens treated as ES grouping (escape inner only)
- All 686 tracker-resources, 19 view-resources, 46 ui tests pass.
- 0 svelte-check errors across all three packages.

User-visible: the All/Active/Backlog/InlineFilterChips redesign now
behaves correctly under heavy navigation + power-user search syntax.

Subject: [PATCH 332/388] fix(ui): escape colons inside prefix values +
 orphan-colon tokens
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Codex Round-6 follow-up to F2: the previous escape pass excluded `:`
from PREFIX_VALUE_RESERVED_RE on the (wrong) assumption that the
tokenizer guarantees no colon in a value. In fact the bare-value
pattern is greedy across non-whitespace so a value can absolutely
contain its own colon — e.g. `title:POC:123` lands at the encoder as
field=searchTitle, value=POC:123. Without escaping that, ES
query_string re-parses the inner colon as another field-targeted
clause, and the whole query crashes.

Two changes:

1. Add ':' to PREFIX_VALUE_RESERVED_RE so any colon in a value triggers
   wrap+escape. `title:POC:123` → `searchTitle:(POC\:123)`,
   `title:12:30` → `searchTitle:(12\:30)`.

2. Add a second pass that escapes orphan colons in tokens that AREN'T
   known-field clauses. Example: `title:meeting 12:30` — pass 1 emits
   `searchTitle:meeting 12:30` because `12:30` has no known-field
   anchor and the regex skips it. Pass 2 escapes that orphan colon so
   ES doesn't try to parse `12` as a field name.

Two new test cases lock in the new behaviour:
- 'wraps + escapes colons inside prefix values' covers title:POC:123,
  title:12:30, comments:bug:fix
- 'escapes orphan colons in bare tokens that follow a prefix clause'
  covers title:meeting 12:30

All 49 ui tests pass (was 46 before Round-5; +3 from Round-5, +3 from
Round-6 colon coverage).

Subject: [PATCH 333/388] fix(ui): broaden orphan-token escaping in
 prefix-routed queries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Codex Round-7 follow-up to F2/F4: the previous second pass only escaped
colons in orphan bare tokens, but once any known prefix appears the
adapter routes the whole string through ES `query_string` — so EVERY
reserved char in a trailing bare token can break the parser, not just
colons. Examples that previously failed:

- `title:meeting C++` → ES parsed `C++` as `C + +` → parse error
- `title:meeting foo/bar` → `/` parsed as regex delimiter
- `title:bug list[0]` → `[`/`]` parsed as range query

Two changes in escapePrefixValues:

1. Broaden the second-pass escape set from just `:` to the full
   PREFIX_VALUE_RESERVED_RE (`+!(){}[]^"~\\/:`). Excludes `-`, `*`,
   `?` — ES tolerates `-` mid-term and the others are legitimate
   wildcards. Excludes AND/OR/NOT as standalone tokens (boolean
   operators), and standalone quoted phrases (ES phrase literals).

2. Replace the `\\S+` tokenizer with a stateful walker that respects
   quoted phrases. Pass 1's output for `title:"foo bar"` is the
   well-formed `searchTitle:"foo bar"` — the naive `\\S+` regex would
   split it into `searchTitle:"foo` + `bar"` at the inner whitespace
   and then escape the trailing `"`, breaking the phrase. The new
   walker tracks quote state per char so `"foo bar"` survives as one
   token regardless of where it sits.

Seven new test cases:
- C++ in orphan position → `C\\+\\+`
- foo/bar in orphan position → `foo\\/bar`
- foo) / list[0] → escaped parens/brackets
- AND/OR/NOT verbatim between tokens
- "release notes" quoted phrase passes through
- *, ? wildcards preserved
- bug-fix hyphen preserved (ES tolerant mid-term)

All 56 ui, 686 tracker-resources, 19 view-resources tests pass.
0 svelte-check errors.

Subject: [PATCH 334/388] fix(ui): capture attached parens as part of prefix
 value
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Codex Round-8: title:foo(bar) slipped through both passes. Pass 1's
bare-value pattern was [^\s()]+ which stopped at the first '(' — so
the regex matched value='foo', emitted 'searchTitle:foo', and the
attached '(bar)' became part of the same whitespace-glued token. Pass 2
then saw a token starting with a known field prefix and passed it
through verbatim, leaving 'searchTitle:foo(bar)' in the wire string
where ES query_string parses it ambiguously.

Fix: widen the bare-value pattern from [^\s()]+ to [^\s]+ so attached
parens / brackets / etc. become part of the captured value. The
paren-wrapped (\([^()]*\)) branch still runs first in the alternation,
so 'title:(scope)' remains correctly captured as paren-wrapped (no
double-escape). Only the case where parens are ATTACHED to a bare
value picks them up in the bare branch and routes through the
reserved-char wrap+escape path.

Trace for the new cases:
- title:foo(bar)  → bare='foo(bar)', '(' reserved → searchTitle:(foo\(bar\))
- title:foo)     → bare='foo)',     ')' reserved → searchTitle:(foo\))
- title:list[0]   → bare='list[0]',  '[' reserved → searchTitle:(list\[0\])
- title:(scope)   → paren-branch matches first (unchanged) → searchTitle:(scope)
- title:loader   → bare='loader',  clean       → searchTitle:loader (unchanged)

Three new test cases:
- 'wraps + escapes prefix values with attached parens' (foo(bar), foo))
- 'wraps + escapes prefix values with attached brackets' (list[0])
- 'keeps user-wrapped parens distinct from attached parens'
  (regression-tests that title:(scope) still passes through bare)

All 59 ui tests pass (was 27 before Round-6; +30 across Rounds 6/7/8).
0 svelte-check errors.

Subject: [PATCH 335/388] refactor(ui): replace 2-pass regex encoder with typed
 tokenizer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Codex Round-8 meta-feedback: 'die Encoder-Logik wird langsam
regex-fragil; nach dem Klammerfall würde ich ernsthaft überlegen, daraus
einen kleinen Tokenizer mit expliziten Token-Typen zu machen.'

Acted on it. The previous escapePrefixValues stacked:
1. A regex-replace pass over <field>:<value> clauses
2. A stateful char-walker pass for orphan tokens

Each Codex round added another corner (colon-in-value, attached parens,
quoted-phrase splitting, broader orphan reserved chars) by tweaking
either pass, and the surface had grown brittle.

New design — single-pass tokenizer + per-type renderer:

  Token grammar:
    ws           whitespace run
    bool-op      AND | OR | NOT (uppercase, standalone)
    quoted       "..."  — pass through unchanged
    field-clause <known-field>:<value> with value kind paren | quoted | bare
    bare         any other non-whitespace run

  Rendering:
    - ws, bool-op, quoted → raw passthrough
    - field-clause / paren    → ${field}:(escapeForQueryString(inner))
    - field-clause / quoted   → ${field}:"${inner}"
    - field-clause / bare     → bare if clean, else wrap+escape
    - bare                    → escape PREFIX_VALUE_RESERVED_RE chars

Each token type now has exactly ONE rendering rule. Future edge cases
(if any) need only either a new token kind or a tweak to the relevant
renderer, not a cross-cutting regex re-think.

Behavior preserved bit-for-bit: all 30 existing encoder tests pass
without modification. 0 svelte-check errors in any of the three
packages (ui / tracker-resources / view-resources).

Subject: [PATCH 336/388] fix(ui): escape leading hyphen in prefix-routed
 search tokens

Prevents Lucene NOT-operator interpretation for inputs like \`title:-foo\`
or \`title:meeting -cancelled\` which were previously sent verbatim to the
Elasticsearch query_string parser and treated as boolean NOT clauses.

Two changes in renderToken (SearchInputAdvanced.encoder.ts):

1. field-clause / bare branch: when value.raw starts with '-', force
   the wrap+escape path so the minus becomes \\- inside parens. Example:
   title:-foo -> searchTitle:(\\-foo). Mid-token hyphens are untouched
   because they only hit this branch when value.raw does NOT start
   with '-' (so HULY-51 still passes through bare).

2. bare branch (orphan token): when tok.raw starts with '-', escape
   the leading minus explicitly, then run the regular reserved-char
   escape over the rest of the token. Example:
   title:meeting -cancelled -> searchTitle:meeting \\-cancelled.

Three new test groups in SearchInputAdvanced.test.ts:
- 'wraps + escapes prefix values starting with a hyphen'
  covers title:-foo and id:-WORK-1
- 'escapes a leading hyphen in orphan bare tokens after a prefix clause'
  covers title:meeting -cancelled
- 'preserves mid-token hyphens in field values and orphan tokens'
  regression for id:HULY-51 and title:meeting bug-fix

All 33 ui SearchInputAdvanced tests pass.

Subject: [PATCH 346/388] fix(view-resources): restore Clear-all filter button
 for non-tracker consumers

The filter-search redesign changed the global FilterButton so it always
opens the add-filter popup (enabling a second filter) and moved the
Clear-all affordance into InlineFilterChips. InlineFilterChips is only
mounted by the Tracker (IssuesView), so the ~16 other FilterBar consumers
(chat, lead, contact, drive, recruit, ...) lost their Clear-all button
entirely.

Render a 'Clear filters' button (IconClose + view.string.ClearFilters,
setFilters([])) in FilterBar's chip row. That row only renders when
hideChips is false, so the Tracker path (hideChips=true) is unaffected
and does not get a duplicate button next to the InlineFilterChips one.

Subject: [PATCH 347/388] fix(view-resources): scope chip overflow-collapse to
 the Gantt toolbar so tracker filter chips render
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

InlineFilterChips applied its 22rem width cap and +N overflow collapsing
unconditionally. That behaviour only makes sense in the crowded Gantt
toolbar row (where chips would push the date-nav / zoom / undo-redo /
fullscreen controls off-screen). In the below-header / list placement
there is a full-width row, so a single moderately-wide chip (Component,
Labels) overflowed the cap and collapsed into the +N popover, removing
its div.filter-section from the main DOM — filter.spec 'Component filter'
and 'Label filter' then could not find the chip.

Add a 'constrained' prop (default false). Unconstrained placements render
every chip inline (legacy behaviour: no cap, wrap, never collapse); the
Gantt inline instance opts in via constrained. computeOverflow and the
overflow badge are untouched and still exercised in the Gantt path.

Subject: [PATCH 348/388] fix(view-resources): drop misapplied .ordering class
 from generic view-option items
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

ViewOptions reused the '.ordering' test-hook class for every 'other'
view-option row, not just the real Order-by dropdown. This was benign
only while all 'other' options were toggles (no <button>). The
filter-search redesign added searchScope as a type:'dropdown' option to
the List/Kanban viewOptions, which renders a DropdownLabelsIntl button
under that same '.ordering' div — so '.antiCard >> .ordering >> button'
(setViewOrder / issues-page.orderingButton) resolved to 2 elements and
the ordering-layout tests hit a strict-mode violation.

'.ordering' carries no CSS anywhere (pure test/semantic hook), so rename
the generic items' class to 'viewoption-other'. The real Order-by
dropdown keeps '.ordering', restoring a unique locator. No test change
needed and no visual impact.

Subject: [PATCH 349/388] fix(tracker): stop empty-state display:none from
 hiding virtualized issue list

The search empty-state collapsed the viewlet wrapper via display:none while
$resultIssueCountStore === 0. Since the pr6 virtualization tier, List/Gantt
viewlets render only what fits their measured viewport; while display:none the
scroller caches a 0-height viewport, so when a freshly created/searched issue's
$search LiveQuery resolves (count 0 -> 1) and the wrapper re-shows, the stale
measurement leaves zero rows rendered. The row's <a> never appears -> the
issues + mentions 'create -> search -> open' uitests time out on the row locator.

Render the empty-state as a non-suppressive sibling instead: never collapse the
live viewlet's layout (keep display: contents for the Gantt height chain, drop
the display:none branch). The virtual scroller always keeps a real viewport and
always renders its rows, so a transient/stale count can no longer hide a
populated list. Matches the earlier top-level-sibling design (8eb61341af).

The query/data path (searchQuery -> FilterBar -> resultQuery) is unchanged and
verified equivalent to develop (searchScope defaults to 'all' -> plain $search
passthrough), so this touches only the render regression, not the filter
redesign or the three already-green filter fixes.

Subject: [PATCH 350/388] fix(view-resources): restore refresh callback so
 async filter results re-trigger the query

The filter-search redesign extracted the query-composition loop into
makeFilterQuery() but called it without the 6th 'refresh' argument, so it fell
back to the no-op default (query-builder.ts:57). develop's inline makeQuery
passed a real callback -- 'result(filter, () => makeQuery(query, filters))' --
to each filter's result-fn, which those async filters invoke when their
underlying value set resolves or changes (e.g. lookup-backed filters). Without
it, such filters never rebuild and re-dispatch the query, so the list can keep
showing stale results after an async filter settles.

Restore the callback by passing '() => void makeQuery(query, filters)' as the
refresh arg. This is byte-for-byte the develop behaviour; makeQuery is
reduceCalls-wrapped, so the re-entrant call is coalesced and cannot spin into an
infinite loop (same guarantee develop relied on).

 input on every keystroke

The prop-sync reactive block read both `value` and `_search`, so Svelte
re-ran it on each bind:value keystroke and reset the field to the (empty)
parent prop. Track lastPropValue separately via reconcilePropValue so the
block no longer depends on _search. Root-cause of the 8 create->search->open

Subject: [PATCH 353/388] fix(view): stable overflow measurement for filter
 chips

- H4: measure against a fixed reference width so collapsed chips can
  re-expand and the collapse spiral cannot drain all chips behind +N
- M-VF4: account for inter-chip flex gaps in computeOverflow
- reserve the real measured badge width instead of the 64px over-estimate

 $search index lag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

my-issues (tracker.spec.ts:54) intermittently failed because a freshly
created issue is not yet in the fulltext $search index when searched, and
the list query does not live-update from the fulltext service. Re-submit
the search under toPass in checkIssuePresenceInTabs so the present-case
assertion tolerates the indexing lag without weakening it — the issue must
still appear, only with retry.

 tolerate $search index lag"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This reverts commit 4ead017406.

CI (run 28921420027) disproved the index-lag premise: tracker.spec.ts:54
my-issues fails identically before and after the retry. The real failure is
NOT lag but a deterministic confound in the negative assertion — the empty
search state renders 'No issues found for "<issueName>"', so the whole
.hulyComponent panel contains the issue name and expect().not.toContainText
fails on the Assigned tab (first tab), before the positive branch is even
reached. Retry-polling the search cannot help. Reverting to keep history
honest; the correct fix (row-count locator instead of panel-text) needs a
separate, reviewed change — reported to the owner.

+ * Architecture (security):
  *
- *  - The bundle does NOT go through the server-side `pushInboxNotifications`
- *    pipeline because that pipeline is keyed off TxCUD context for the
- *    *originating* doc — we'd lose the trigger-user / cascade-set context.
- *    Creating the notification doc directly is the simplest path that keeps
- *    the bundle payload intact end-to-end.
+ *  - The client NO LONGER writes `DocNotifyContext`/`DependencyShiftedNotification`
+ *    directly into recipients' `PersonSpace`s. That was a spoofing/ACL hazard:
+ *    a client could forge inbox notifications with an arbitrary `triggerUserId`
+ *    into foreign spaces. Instead the server trigger `OnDependencyShiftRequest`
+ *    resolves collaborators + recipient spaces privileged and derives the
+ *    trigger user from `tx.modifiedBy` (never from the payload).
  *
- *  - Suppression of the auto-generated `dueDate` notification (spec §3.3) is
- *    a Known Limitation in v1: `TxApplyIf.scope` (= `cascadeToken`) is
- *    consumed inside `ApplyTxMiddleware` before the trigger pipeline sees
- *    the inner Txes, so a server-side trigger cannot tell a cascade update
- *    apart from a manual edit. Follow-up: surface the cascade-token through
- *    a trigger-visible attribute or wrap the cascade Tx in a custom Tx-mixin.
- *
- *  - The `DocNotifyContext` that normally accompanies an inbox notification
- *    is intentionally omitted in v1; the recipient sees the entry in their
- *    inbox via the `user` + `space` routing keys on the notification
- *    itself, which is the same path `MentionInboxNotification` relies on.
+ *  - Only the pure per-issue payload construction (`buildPayloadFrom*`) stays
+ *    client-side; the collaborator/space resolution and the notification writes
+ *    moved into the server trigger.

Subject: [PATCH 362/388] test(tracker): assert on issue rows, not panel text,
 in checkIssuePresenceInTabs

The my-issues tab check used expect('.hulyComponent').not.toContainText(name),
but the empty-state renders the search echo (No issues found for "<name>"),
so the negative text assertion matched the echo and failed. Switch to the
established linesFromList row-count locator (toHaveCount 0/1), which targets a
real issue row and ignores the search echo. Strengthens the assertion; last
tracker uitest fail.

Subject: [PATCH 363/388] fix(view): close filter-overflow popover on
 filter-set change (no stale split)

InlineFilterChipsOverflow receives hiddenStartIndex as a one-shot snapshot of
visibleCount while its {#each $filterStore} body stays live. When the filter
set changes with the popover open, the snapshot points at the wrong subset
(M-VF3). Subscribe to filterStore on open and close the popover on the first
real mutation; clean up the subscription on user-close and on destroy.

Subject: [PATCH 364/388] docs(elastic): document why query_string
 field-targeting is space-ACL-safe (M-VF5)

Verified that raw query_string field-targeting in FullTextAdapter.search cannot
leak cross-space or cross-workspace data: workspaceId is a hard bool.must term,
and the sole caller (fulltext /api/v1/search via FullTextMiddleware) sits below
SpaceSecurityMiddleware, which either bakes the space constraint into the DB
findAll or post-filters via clientFilterSpaces. The ES hits are only a candidate
id-set, re-filtered downstream. No whitelist gate needed; record the proof.

Subject: [PATCH 376/388] fix(gantt): critical-path cycle check runs on
 scheduled relations only (L-G3)

detectCycle previously ran on the full unfiltered relation graph before the
scheduled filter, so a cycle among purely unscheduled issues wrongly disabled
the whole critical-path panel. Move the check after activeRels is derived so
only cycles among scheduled relations degrade the result.

- L-G1: generation-guard the async editableIssueIds IIFE so an older,
  slower canEdit chain can no longer overwrite the Set with a stale value.
- L-G4: gate the Tab/Arrow/+/- shortcuts behind isTextInputFocused() and
  only trap Tab when a bar has focus, so text inputs inside the Gantt root
  keep native typing/caret behaviour and keyboard users are never stuck.
- L-G9: precompute a Set of issues touched by a violated relation once per
  change instead of rescanning all relations for every rendered row.
- L-G2: inject the Issue/IssueRelation class refs into UndoManager (defaults
  preserved for the unit mocks) and align the apply() JSDoc/adapter with the
  real TxOperations.apply(scope,...) — the marker is the apply scope.

gotoAllIssues truncates the route to the allIssues special view and does not
carry the search text. The header comment claimed the opposite; align the

Subject: [PATCH 385/388] fix(view): bind filter-overflow badge aria-expanded
 to popover state (L-VF6)

aria-expanded was hardcoded false; bind it to the live popover handle so AT
users get the real disclosure state. Also drop the stale IconClose dead-code
comment (the icon is used by the clear-all button).

Subject: [PATCH 386/388] fix(view): intersect $lte/$gte date bounds when
 merging filters (L-VF7)

Date filters emit $lte/$gte, but the key-merge only handled $lt/$gt, so two
date filters on one key fell through to Object.assign (last wins) instead of
tightening the range. Add $lte/$gte branches keeping the tighter bound.

Subject: [PATCH 388/388] fix(view): apply #10969 filtered-view visibility gate
 to the Tracker save-row path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The develop merge brought in #10969's canSaveFilteredView gate, but it only
guarded the legacy chip-row save button. The branch-new showSaveRow path
(Tracker IssuesView, hideChips=true) renders SaveAs/Save without the gate, so a
ReadOnlyGuest/DocGuest would still see them. Add canSaveFilteredView to
showSaveRow — in that path the row is save-buttons only, so hiding it for guests
matches upstream intent (chips render separately via InlineFilterChips).
