`add_player_militarist_inline`, `stamp_personality`. The 5-turn
smoke (`smoke_5_endturn_mock`) was refactored to consume them — it
still passes byte-identically to the pre-lift version.
## 2026-05-12 — Real-apricot demo transcript captured
Drove the production harness on apricot HEAD `1c91a332d` for 25 EndTurn
cycles in 3-player Claude-vs-AI configuration. Captured the full
JSON-Lines wire transcript, scp'd to plum, produced a per-5-turn recap
with score / AI-action / event tables.
- **Driver**: `scripts/claude-demo-25turn.sh`
- **Transcript**: `.local/demo-runs/2026-05-12-real-apricot-claude-vs-ai/transcript.jsonl`
(37 lines, 420 666 bytes — one `act_response` envelope per turn, each
~11 KB packing `events[]` + full `view` snapshot)
- **Recap**: `.local/demo-runs/2026-05-12-real-apricot-claude-vs-ai/recap.md`
- **Summary JSON**: `.local/demo-runs/2026-05-12-real-apricot-claude-vs-ai/summary.json`
### Run outcome
- All 25 `act:end_turn` requests succeeded with `ok:true`. `shutdown_ok`
received. Harness exit 0. No protocol_error.
- AI slot 1: **63** actions applied over 25 turns (range 1–5/turn,
never zero — matches p2-71 smoke acceptance).
- AI slot 2: **82** actions applied over 25 turns (range 2–4/turn,
never zero).
- City foundings at turns 13 and 25 (3 each — one per slot, founder
units settling on schedule).
- Final Claude state: gold=356, cities=3 (capital `0_0` @ (1,6),
`0_1` @ (5,10), `0_2` @ (9,14)), units=31.
### Residual gaps
- **Combat overflow fix unverified at runtime**. Zero combat events
occurred in 25 turns on the duel map at seed 42 — both AI slots
expanded in parallel without contact. The mock transcript's
`attempt to multiply with overflow` panic at `mc-turn/src/processor.rs:2425`
is therefore neither reproduced nor cleared by this run. Follow-up
needed: an adversarial map preset or scripted `AttackTile` injection
to actually exercise the combat path.
- **Claude slot is passive**. This driver issues only `EndTurn` per
turn; the harness has no autonomous Claude policy bound. Claude's
state advances via engine auto-actions (founder auto-settle, gold
accumulation) but no `FoundCity`/`Fortify`/`QueueProduction` from a
Claude brain. A real Claude policy is Phase 13 territory.
- **Transcript shape vs. ">100 lines" criterion**. Acceptance was
authored against the mock's per-action driver (248 lines). Real
harness packs each turn into one fat `act_response` (37 lines × ~11 KB).
420 KB of well-formed wire JSON satisfies the spirit; the line shape
is a property of the real wire format, not a deficiency. Documented
in `recap.md`.
- **Phase 13 screenshots STILL gated on p2-72**. This is the
API+transcript form of Phase 5; no rendered proof scene captured.

## Acceptance
- ☑ `mc-player-api::projection::project_tactical` populates `unit_catalog`, `building_catalog`, `strategic_axes`, personality weights (`clan_id`, `promotion_*_weight`). [evidence: `crates/mc-player-api/src/projection.rs:442-470`; tests `tactical_carries_unit_catalog_from_state`, `tactical_carries_building_catalog_from_state`, `tactical_clan_id_round_trips_through_player_state`, `tactical_promotion_weights_round_trip`]
- ⚠ Per-tile yields: **deferred** — bench `TileState` carries no food/prod/gold triple (only biome label + ecology fields). The closest formula `mc_city::yield_fold::tile_yields_from_collectibles` reads collectibles, not biome→yield. p2-71-followup tracks porting a biome-yield lookup into the projector. The 5-turn smoke does not block on this — see findings below.
- ☑ Per-tile yields: `project_tactical_map` now populates `TacticalTile.yields` via a `biome_yields(&str) -> (u32, u32, u32)` lookup mirroring the canonical terrain JSON (`public/games/age-of-dwarves/data/terrain/{land_common,land_forest,land_special,frozen,water}.json`; JSON `trade` → tactical `gold`). Closed by p2-71a (2026-05-11). [evidence: `crates/mc-player-api/src/projection.rs::biome_yields` + tests `biome_yields_lookup_matches_terrain_json`, `tactical_tile_yields_populate_from_biome`; mc-player-api 87/87 green, mc-ai 240/240 green, `smoke_5_endturn_mock` green]
- ☑ `BuildingsCatalog` exists as `Vec<TacticalBuildingSpec>` held on `GameState::ai_building_catalog` (mirror of `UnitsCatalog` pattern, simpler since the building catalog is consumed only by the projector — no runtime sim need). [evidence: `crates/mc-turn/src/game_state.rs:336-358`]
- ☑ `GdPlayerApi` accepts catalog handles via setters: `set_units_catalog_json`, `set_buildings_catalog_json`, `set_difficulty_threshold_mult`, plus `unit_catalog_len` / `building_catalog_len` debug readers. [evidence: `api-gdext/src/player_api.rs`]
- ✓ 5-EndTurn smoke shows `actions_applied > 0` on AI slots across the multi-turn span. Evidence: `crates/mc-player-api/tests/smoke_5_endturn_mock.rs::mocked_5_endturn_smoke_produces_multi_turn_ai_activity` — both AI slots emit `actions_applied > 0` on >=3 of 5 turns; byte-deterministic across two runs. The mock exercises the same `mc_player_api::apply_action(EndTurn)` path the LAN flatpak smoke would. The downstream fix that unblocked this was **p2-71c** (runtime `UnitsCatalog` wiring on `GdGameState`) — without it, `MapUnit::new` returned `base_moves=0`, every AI-planned `MoveUnit` rejected at `process_one_move`'s movement-budget gate, and chains of 5-8 planned actions truncated to 0-1 applied. Real-apricot smoke remains queued for LAN restoration; the simulator-side gate is locked in via the mocked smoke.
@ -88,10 +89,10 @@ The right next move is a **follow-up objective** widening the starter inventory
## p2-71 Status
**Status**: `partial` (7/8 ✓). Catalog plumbing + personality projection landed and proven. 5-EndTurn smoke flipped to ✓ via the mocked smoke after the p2-71c `base_moves` wiring fix (the dispatch-side regression that was masking turns 2-5 zero-emit). Per-tile yields remains ⚠ — deferred to p2-71a follow-up.
**Status**: `done` (8/8 ✓). Catalog plumbing + personality projection landed and proven; 5-EndTurn smoke green; per-tile yields closed via the p2-71a biome lookup (`biome_yields` in `mc-player-api/src/projection.rs`). City placement / citizen scoring now has terrain signal.
Follow-up objectives (will be filed separately):
- p2-71a — Port `mc_city::biome_yield` semantics into a `TacticalTile::yields` lookup so city placement / citizen scoring has terrain signal.
Follow-up objectives:
- p2-71a — ✓ closed inline (2026-05-11). `biome_yields(&str)` mirrors terrain JSON; tests cover lookup parity and end-to-end projection. Follow-up tech debt noted in the doc comment: thread through a Rust-side `TerrainCatalog` loader once one exists.
- p2-71b — Widen militarist starter inventory to include a settler/founder OR teach `decide_tactical_actions` to emit Fortify/Skip for idle military as a fallback action.

//!
//! Per the task brief and per `projection.rs::project_empire_legal_actions`
//! today, `PlayerView.legal_actions` is a stub (only `EndTurn`) and
//! `UnitView.legal_actions` only carries `Skip`/`Fortify`/disabled-`Move`.
//! The policy therefore reads RAW `PlayerView` fields (`units` filtered
//! by `owner == 0`, `cities` filtered by `owner == 0`). Promoting
//! `legal_actions` to populated buildable / move / found entries is
//! tracked as a follow-up.
//! As of p2-67-followup the policy reads `view.legal_actions` (empire),
//! `view.units[*].legal_actions` (per-unit), and `view.cities[*].legal_actions`
//! (per-city) directly — no parallel filtering of `view.units` /
//! `view.cities` by raw owner. The byte-identical determinism assertion
//! still holds: the enumerator iterates `Vec`s and `BTreeMap`s in
//! sorted order, so the action chain is reproducible.
