The conversion from `McSnapshot` → `MctsJobState` is **intentionally lossy** — `science_pool`, `tech_index`, `happiness_pool`, `force_relations`, `relations` are all zeroed because the abstract rollout state has a narrower view than the strategic snapshot. This works for the 3-action `McAction` taxonomy but degrades the AI's quality of judgement vs the local `Tree::simulate_parallel` path. + +Per cycle 3 specialist's analysis: a cleaner additive shape exists. Add a NEW method `value_estimate_abstract(MctsJobState_json) -> f32` on `GdMcTreeController` that calls the service for state-evaluation queries that already live in the abstract domain (e.g. tactical leaf evaluation, future GPU-batched leaves work). `choose_action*` stays untouched (local Tree path); the service gets a real, non-lossy caller via the new method. + +## Acceptance + +- ❌ New `#[func] fn value_estimate_abstract(&self, state_json: GString, n_rollouts: i64, depth: i64, seed: i64) -> f32` on `GdMcTreeController` in `src/simulator/api-gdext/src/ai.rs`. Signature mirrors the existing `MctsJob` shape; returns the `value` field from `MctsResult` (or `f32::NAN` on service error / fallback). +- ❌ At least one in-codebase caller exercises the method — e.g. tactical AI's leaf evaluator OR a GPU-batched-leaves benchmark in `mc-ai/tests/`. +- ❌ Round-trip integration test in `tests/value_estimate_round_trip.rs` (or extension of existing service test) confirming a known seed produces a deterministic value. +- ❌ `choose_action*` path preserved — its 3-job batch + argmax fallback shape is NOT removed (still useful for the strategic-action use case until p1-27e tackles the SearchAction protocol extension). + +## Why P2 + +p1-27c's lossy 3-batch path ships AI that works (local Tree fallback covers the quality gap). This additive method improves architecture cleanliness and unlocks the GPU-batched-leaves work but isn't a launch-blocker. + +## Non-goals + +- Replacing `choose_action*` integration with this method (different domain). +- SearchAction protocol extension to do full tree search server-side — tracked separately as p1-27e if/when needed. diff --git a/src/game/engine/scenes/tests/placement_mode_proof.gd b/src/game/engine/scenes/tests/placement_mode_proof.gd index a9133dd4..6dc2a22c 100644 --- a/src/game/engine/scenes/tests/placement_mode_proof.gd +++ b/src/game/engine/scenes/tests/placement_mode_proof.gd @@ -135,4 +135,10 @@ func _test_eventbus_signals() -> void: func _report() -> void: - print("[placement_mode_proof] Results: %d passed, %d failed" % [_pass_count, _fail_count]) + var summary: String = "Results: %d passed, %d failed" % [_pass_count, _fail_count] + print("[placement_mode_proof] %s" % summary) + var results_path: String = "user://placement_proof_results.txt" + var f: FileAccess = FileAccess.open(results_path, FileAccess.WRITE) + if f != null: + f.store_string(summary + "\n") + f.close() diff --git a/src/game/engine/tests/unit/test_diplomacy.gd b/src/game/engine/tests/unit/test_diplomacy.gd index 6204e3db..2e030aa1 100644 --- a/src/game/engine/tests/unit/test_diplomacy.gd +++ b/src/game/engine/tests/unit/test_diplomacy.gd @@ -11,6 +11,7 @@ const DiplomacyScript: GDScript = preload( const HappinessScript: GDScript = preload( "res://engine/src/modules/empire/happiness.gd" ) +const PlayerScript: GDScript = preload("res://engine/src/entities/player.gd") # --------------------------------------------------------------------------- @@ -18,15 +19,15 @@ const HappinessScript: GDScript = preload( # --------------------------------------------------------------------------- func _make_player(idx: int, is_human: bool = false) -> RefCounted: - var p: RefCounted = RefCounted.new() - p.set_meta("index", idx) - p.set_meta("is_human", is_human) - p.set_meta("traded_luxuries", []) + var p: PlayerScript = PlayerScript.new() + p.index = idx + p.is_human = is_human + p.traded_luxuries = [] return p func _get_traded(player: RefCounted) -> Array: - return player.get_meta("traded_luxuries") + return player.get("traded_luxuries") # --------------------------------------------------------------------------- @@ -77,7 +78,7 @@ func test_apply_trade_changes_populates_traded_luxuries() -> void: func test_apply_trade_changes_clears_stale_luxuries() -> void: var pa: RefCounted = _make_player(0) - pa.set_meta("traded_luxuries", ["stale_gem"]) + pa.set("traded_luxuries", ["stale_gem"]) var pb: RefCounted = _make_player(1) var players: Array = [pa, pb] @@ -129,52 +130,19 @@ func _make_game_map_stub() -> RefCounted: func test_collect_unique_luxury_ids_includes_traded_luxuries() -> void: - var player: RefCounted = _make_player(0) - player.set_meta("traded_luxuries", ["sapphire"]) - player.set_meta("cities", []) - - # happiness.gd reads player.traded_luxuries via direct property access (not get_meta). - # We need a real Player-like object with actual fields.
