|

2026-04-16 17:03 TEST COVERAGE MANDATE escalated by user: "all code covered", "all business logic tested", "all e2e and integration logic tested". Memory updated. Every spawn from now on includes test-coverage acceptance gate. New spawns: json-schema-dev (#70 data), gut-expansion-dev (#71 city/turn/combat GUT), crash-e2e-dev (#72 seed-5 crash + E2E gate), gpu-b2-dev (#73 WGSL fauna kernel), mcts-a2-dev (#74 MCTS wired to real state-advance).
|
||||
2026-04-16 17:03 CRITICAL FIND: verify batch exit-zeroed while seed 5 crashed mid-game. autoplay-batch.sh wrapper did not fail loud. crash-e2e-dev spawned to fix both root cause (auto_play.gd:1737) AND the gate masking.
|
||||
2026-04-16 17:03 VERIFY BATCH (9 of 10 good, seed 5 crashed): victory rate 3/10 — slight regression from prior thorough 4/10. Hypothesis: removing wild-player combat (post wild-distance fix) lost a tempo disruptor for certain seeds. Not re-tuning until crash fixed + rerun clean.
|
||||
2026-04-16 17:10 WAVE TWO COMPLETIONS:
|
||||
- #70 json-schema-dev: 8 schemas (unit/building/tech/terrain/improvement/race/wilds/ai_personality), validator at tools/validate-game-data.py, wired into ./run verify. 109 entries validated clean; caught latent spearmen.json legacy-schema bug as a byproduct. ~220 LOC.
|
||||
- #71 gut-expansion-dev: 34 new GUT tests across test_city (14), test_turn_processor (10), test_combat_bridge (12). Total suite now 119 tests, 107 pass, 1 pre-existing failure (iron_axe, unchanged), 11 pending. GDScript coverage on business logic materially closer to complete.
|
||||
Test-coverage mandate response is paying off: data changes, city state transitions, and combat bridge math now have unit-level protection separate from end-to-end batches.

## T15: EventBus payload correctness.
|
||||
##
|
||||
## Locks the signal-parameter contract for three high-traffic EventBus
|
||||
## signals: unit_moved, city_founded, tech_researched. The engine emits
|
||||
## these from multiple producers (movement, AI tactical, turn processor,
|
||||
## world_map, ai_turn_bridge) — any drift in parameter order/shape would
|
||||
## silently break every listener downstream.
|
||||
##
|
||||
## Strategy: drive the signals via their two canonical paths —
|
||||
## (1) direct `EventBus.<sig>.emit(...)` (what production code does),
|
||||
## (2) a connected listener that records payloads for shape assertions.
|
||||
## We do NOT rely on the Rust turn processor here; that shape is locked
|
||||
## separately in `test_gd_turn_processor.gd`. The EventBus itself is the
|
||||
## contract under test.
