Code Review
This pull request introduces a significant and impressive playable slice of the game, including the core loop controller, deterministic math modules, and a refreshed UI. The code is well-structured, with good separation of concerns and a solid testing foundation. My review focuses on improving long-term maintainability. The main points are the temporary reduction in test coverage thresholds, which should be addressed, and the widespread use of 'magic numbers' for game balancing and scoring. Extracting these hardcoded values into named constants or configuration objects will make the game much easier to tune and evolve. Overall, this is a fantastic step forward for the project.

The test coverage thresholds have been significantly lowered in this change. While this might be a temporary measure to merge a large feature, it represents a notable reduction in our code quality standards. It would be beneficial to discuss the plan for restoring these thresholds to their previous levels (e.g., 90%) to ensure long-term maintainability and reliability of the codebase.

The star rating thresholds are hardcoded here. Throughout the GameApp class, there are many similar 'magic numbers' for game balance (e.g., enemy count formula in enterSkirmish), scoring (e.g., multipliers in handleGateChoice), and timing. To improve maintainability and make it easier to tune the game, consider consolidating these values into a configuration object or a set of named constants at the top of the file or in a separate config file.

The logic for picking gate operations contains several hardcoded 'magic numbers' that define the range and values for the math operations (e.g., 3 + Math.round(rng() * 12), currentCount * 0.45, 1.2 + rng() * 1.1). These values are critical for game balance. Extracting them into a configuration object, perhaps within OPERATION_CONFIG or a new structure, would make them easier to find, understand, and tune.

The values 0.2 and 0.6 used to determine the next target lane are hardcoded. To improve clarity and make game balance easier to adjust, these 'magic numbers' should be defined as named constants at the top of the file, for example TARGET_LANE_MIN_OFFSET and TARGET_LANE_RANGE.
| export function rollNextTargetLane(rng = Math.random) { | |
| const lane = 0.2 + rng() * 0.6; | |
| return clamp(lane, 0, 1); | |
| } | |
| const TARGET_LANE_MIN_OFFSET = 0.2; | |
| const TARGET_LANE_RANGE = 0.6; | |
| export function rollNextTargetLane(rng = Math.random) { | |
| const lane = TARGET_LANE_MIN_OFFSET + rng() * TARGET_LANE_RANGE; | |
| return clamp(lane, 0, 1); | |

This simulation loop contains a few hardcoded 'magic numbers' that affect game balance and behavior:
- The loop condition
ticks.length < 24acts as a safeguard against infinite loops, but the number 24 is arbitrary. It should be a named constant likeMAX_SKIRMISH_TICKS. - The damage formula exponent
0.85is a key balancing parameter. - The random factor
0.3in casualty calculation adds variance.
Extracting these into constants at the top of the file would improve readability and make tuning the skirmish mechanics more straightforward.
