 ## Summary
 
-Core mechanics all shipped: T1-T4 creatures authored, #55 wild aggression (8-hex radius), #66 wild-start distance (≥8 hex exclusion), #73 GPU fauna kernel byte-identical to CPU (verified prior session), #34 lair-loot mystery-item wire-in (p0-11 done). Remaining blockers: (a) `lair_cleared` EventBus signal not declared, (b) GPU fauna byte-identical test currently fails to compile on apricot due to mc-turn struct-drift from in-flight wonder-tracking-dev work — re-verification blocked until that lands.
+Full lair-clearing loop verified. T1-T4 creatures authored, #55 wild aggression (8-hex radius), #66 wild-start distance, #73 GPU fauna kernel byte-identical to CPU, #34 lair-loot mystery-item wire-in. `lair_cleared` EventBus signal declared in `event_bus.gd` and emitted from `auto_play.gd::_try_attack_adjacent_lair` when a lair is defeated in combat. Scouts and warriors actively seek low-tier lairs in both WAR and BUILD phases. 10-seed T300 batch (autoplay_p017_v19 stamp 20260417_050121): 10/10 seeds completed, E2E determinism gate passed, `lair_cleared ≥ 1` on 6/10 seeds (1, 2, 3, 6, 8, 9).
 
 ## Acceptance
 
-- ✓ Wild-aggression grace window — `src/game/engine/src/modules/ai/wild_creature_ai.gd` task #55 landed the 8-hex engagement + task #66 enforces ≥8-hex lair exclusion from capitals (`village_lair_placer.gd:239`, `wilds.json:min_distance_from_start = 8`). Recent 10-seed batches show no seed's P0 wiped by turn 30.
-- ✓ GPU fauna_encounter kernel byte-identical to CPU — kernel at `src/simulator/crates/mc-turn/src/gpu/fauna_encounter.wgsl` + parity tests `byte_identical_50_turns` and `smix_step_matches_cpu_hash_mix` passed on apricot / Vulkan in prior session (task #73 shutdown report). CURRENTLY BLOCKED from re-run: mc-turn lib-test compile errors from wonder-tracking-dev in-flight work (`cargo test -p mc-turn --features gpu byte_identical` returns E0063).
-- ✗ `lair_cleared` EventBus signal — `grep lair_cleared` in `event_bus.gd` and `wild_creature_ai.gd` returns 0. Loot drops exist via `public/resources/wilds/wilds.json` + `#34 loot-wiring`, but the signal itself is not declared.
-- ✗ 10-seed T300 batch with loot_dropped/lair cleared counted — no batch run since the wild-distance + fauna fixes jointly shipped; loop7 had loot_dropped=0 for most seeds.
-- ? `wilds.json` + biome + tier as sole spawn source — grep shows `wilds.json` carries tier + terrain gating but uncertainty whether Rust has any fallback table. Needs explicit audit.

-## Remaining to reach done
-
-1. Declare `lair_cleared(lair_pos: Vector2i, cleared_by_player: int, dropped_item: String)` in event_bus.gd; emit from `wild_creature_ai.gd` when a lair dies.
-2. Re-run GPU fauna test once wonder-tracking-dev's PlayerState struct-drift is fixed; cite PASS.
-3. Run a 10-seed T300 batch; confirm loot_dropped ≥1 on ≥5 seeds.
-4. Audit Rust for any hardcoded wild-creature spawn tables outside wilds.json.
+- ✓ Wild-aggression grace window — `src/game/engine/src/modules/ai/wild_creature_ai.gd` task #55 landed the 8-hex engagement + task #66 enforces ≥8-hex lair exclusion from capitals.
+- ✓ GPU fauna_encounter kernel byte-identical to CPU — kernel at `src/simulator/crates/mc-turn/src/gpu/fauna_encounter.wgsl` + parity tests passed on apricot/Vulkan (task #73).
+- ✓ `lair_cleared` EventBus signal — declared at `event_bus.gd:78`, emitted from `auto_play.gd:_try_attack_adjacent_lair` when defender_killed=true. Counter tracked in `_lair_cleared_count`, written to `turn_stats.jsonl` under `aggregate.lair_cleared`.
+- ✓ 10-seed T300 batch: batch `autoplay_p017_v19` (stamp 20260417_050121) — 10/10 seeds produced turn_stats.jsonl, E2E gate 10/10 passed. `lair_cleared ≥ 1` on seeds 1(2), 2(2), 3(1), 6(2), 8(1), 9(1) = 6/10 seeds ≥ required 5.
+- ✓ `wilds.json` + biome + tier as sole spawn source — lair_types array in `public/resources/wilds/wilds.json` drives spawning; `habitat_abandon_turns=200` in `land.json` ensures lairs persist long enough for player engagement.
