…cation (#50) HashMap determinism (REQ-14): - Replace 5 iteration-order-sensitive HashMaps with BTreeMap in lib.rs: coloring, local_info, last_sets/block_sets/loop_sets/then_sets, color_types, old_idx_to_type, global_constants - Ensures identical inputs always produce identical outputs Safety-case GSN artifacts: - 6 safety goals (SG-1 to SG-6) covering all 20 hazards - 2 safety strategies (SS-1, SS-2) - 5 safety solutions (SOL-1 to SOL-5) as evidence - 1 safety context (SC-CTXT-1) - stpa-hazards-have-safety-goals: 0% → 100% ISLE rule verification groundwork (#50): - Z3-based verification of constant folding rules - Proves i32/i64 add/sub/mul rules correct for all 2^N inputs - 8 new tests: per-rule verification + integration suite Trace: REQ-14, REQ-6, SG-1, SG-2 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
