 ## Acceptance
 
-- [ ] `PlayerState` carries `building_category_weights` + `wonder_priorities`.
-- [ ] `project_player` seeds `TacticalPlayerState::building_priors` from `PlayerState`, not `default()`.
-- [ ] All 5 clan personality JSONs author non-neutral weights.
-- [ ] `mc-ai/tests/personality_building_bias.rs` — identical city state, production-axis personality scores `forge` higher than `marketplace`; wealth-axis personality reverses.
+- [x] `PlayerState` carries `building_category_weights` + `wonder_priorities`.
+  - Evidence: `src/simulator/crates/mc-turn/src/game_state.rs` — added
+    `pub building_priors: mc_ai::tactical::state::BuildingPriors` field
+    (wraps both maps in one struct, mirrors how the tactical state already
+    carries them). `#[serde(default)]` keeps pre-p1-42b saves loading.
+- [x] `project_player` (i.e. `project_tactical_player`) seeds
+  `TacticalPlayerState::building_priors` from `PlayerState`, not `default()`.
+  - Evidence: `src/simulator/crates/mc-player-api/src/projection.rs:1158-1166`
+    now reads `player.building_priors.clone()` straight through. Covered by
+    `tactical_building_priors_round_trip_from_player_state` +
+    `tactical_building_priors_default_for_unstamped_player` (both pass on
+    apricot, see `cargo test -p mc-player-api --lib tactical_building_priors`).
+  - Bridge wiring: `api-gdext/src/lib.rs::set_player_personality_json`
+    now reads `building_category_weights` and `wonder_priorities` from the
+    personality JSON envelope and stamps them onto
+    `PlayerState::building_priors`. Absent keys reset to empty so re-stamping
+    can never leak a prior clan's priors.
+- [x] All 5 clan personality JSONs author non-neutral weights.
+  - Evidence: `public/games/age-of-dwarves/data/ai_personalities.json` —
+    every clan (`ironhold`, `goldvein`, `blackhammer`, `deepforge`,
+    `runesmith`) now carries both `building_category_weights` (7 cats) and
+    `wonder_priorities` (clan-flavoured wonder picks). Schema accepts via
+    `additionalProperties: true`. JSON validates (`python3 -c "import json; ..."`).
+- [x] `mc-ai/tests/personality_building_bias.rs` — identical city state,
+  production-axis personality scores `forge` higher than `marketplace`;
+  wealth-axis personality reverses.
+  - Evidence: new integration test at
+    `src/simulator/crates/mc-ai/tests/personality_building_bias.rs`.
+    Drives `decide_tactical_actions` end-to-end with neutral strategic
+    axes (isolating the priors path from the cycle-5 axis fall-through)
+    and a two-building catalog. Result on apricot:
+    ```
+    running 2 tests
+    test empty_priors_fall_through_to_default_behaviour ... ok
+    test production_priors_pick_forge_wealth_priors_pick_marketplace ... ok
+    test result: ok. 2 passed; 0 failed
+    ```
+- [x] Headless regression check — `cargo test -p mc-turn --lib` (220
+  passed), `cargo test -p mc-player-api --lib` (91 passed), `cargo test -p
+  mc-ai` (full suite green incl. `ultimate_lookahead_stress` + the new
+  `personality_building_bias`), `cargo check -p magic-civ-physics-gdext`
+  clean. No regressions touched.
