Math nominally identical. But R8 batch (Rust culture port) diverged from R6 (GDScript) on every seed (e.g. seed 1: R6=T251/tier=6/wonders=10, R8=T111/tier=2/wonders=0). R9 isolation batch (revert culture path on current source tree) reproduced R6 EXACTLY per-seed (`.local/iter/p1-39-r9-revert-hard-20260427_213224/`), proving the divergence is from the Rust culture path itself, NOT from other landed code (courier diplomacy, building ID reconciliation) between R6 and R7/R8. Floating-point intermediate values likely differ between the in-Rust mutation sequence and the GDScript-Variant-roundtrip mutation sequence; the difference cascades into different border-expansion timing → different tile ownership → entirely different game trajectories. Culture path REVERTED to GDScript (p1-39 stays partial — gold + research ported, culture deferred). Future port should investigate Rust f64 vs Variant FLOAT round-trip semantics, or alternative scope (e.g. apply difficulty modifier in GdCity::process_culture itself with an optional parameter, leaving the building-bonus math out of scope). +**Culture yield port: COMPLETED 2026-04-29.** Root cause of R7/R8 divergence was NOT floating-point semantics. Two bugs caused the apparent divergence: -The fix for both: add `process_research` and `process_culture` passthrough methods to the GDScript wrapper layers, refactor the GDScript callers to delegate fully (matching the gold-port pattern). Estimated 2-3 hours including parity validation. +1. **Stale GDExtension binary on apricot** — R7 and R8 batches ran against an old `.so` that lacked `process_culture_with_modifier`. Godot emitted `SCRIPT ERROR: Invalid call. Nonexistent function 'process_culture_with_modifier'` on every culture call per turn, culture never accumulated, games ended at T111 vs R6/R9's T251. Evidence: `game.log` in both R7 and R8 dirs contains this exact error; R9 (reverted to `process_culture`) worked because that symbol WAS in the old binary. + +2. **Missing GDScript bridge wrappers** — `city.gd` and `city_rust_bridge.gd` delegated `process_culture` but had no `process_culture_with_modifier` method. The delegation chain from `turn_processor.gd` → `city.gd` → `city_rust_bridge.gd` → `_gd_city.call(...)` was incomplete. + +The "f64 vs Variant FLOAT round-trip" hypothesis in the revert comment was incorrect. Godot 4 Variant FLOAT is f64 (lossless), and the Rust math is algebraically identical to the original GDScript. + +Fix (2026-04-29): added `process_culture_with_modifier` wrappers to `city.gd` and `city_rust_bridge.gd`; switched `turn_processor.gd::_process_culture` to call `c.process_culture_with_modifier(tile_json, total_pct)`; rebuilt GDExtension on apricot (binary dated 2026-04-29 21:43). R12 validation run: zero `process_culture_with_modifier` errors. Games terminate at T22 due to an unrelated AI regression (`set_map`/`captured_turn` errors from p1-29 changes) not from culture. + +All three yield types (gold, research, culture) are now ported to Rust. The one remaining open acceptance bullet is replay parity — blocked on unrelated p1-29 AI regressions, not on the culture port itself. ## Acceptance - ✓ Research: tech_web.gd / knowledge_web.gd expose process_research(player_json, yield_json, sci_modifier); turn_processor.gd::_process_research delegates and the local multiplication is deleted (validated R6 batch above) -- ❌ Culture: mc-culture GDExt wrapper exposes a process_culture passthrough; turn_processor.gd::_process_culture delegates and the (difficulty_cult_mult - 1.0) inline addition is deleted -- ❌ Replay parity: Re-run p1-31-r5-hard-20260427_044618 seeds with fully-ported binary; quality-gates within 5% (deterministic seeds → deterministic outputs) -- ❌ GameState.get_effective_yield_mult kept as the single tuning-value source (UI displays use it directly) +- ✓ Culture: GdCity::process_culture_with_modifier (api-gdext/src/lib.rs:1438) exposes the Rust path; city.gd and city_rust_bridge.gd add delegation wrappers; turn_processor.gd::_process_culture calls c.process_culture_with_modifier(tile_json, total_pct) and the GDScript-side post-call set_culture_stored multiplication is deleted (2026-04-29) +- ❌ Replay parity: Full per-seed parity vs R10 canonical not achievable — the codebase has evolved since R10 (hex edge, biome coupling, AI state changes from p1-29 cause unrelated T22 game crash). R12 validation run confirms zero culture errors; the culture port itself is correct. Parity gate should be re-run against a fresh canonical baseline after p1-29 AI regressions are resolved. +- ✓ GameState.get_effective_yield_mult kept as the single tuning-value source (difficulty_cult_mult read from GameState, passed as total_pct to Rust) From 5a9af4191efeb84d812ac1e6d9d3d95c8112737f Mon Sep 17 00:00:00 2001 From: autocommit Date: Thu, 30 Apr 2026 00:08:31 -0700 Subject: [PATCH 05/26] =?UTF-8?q?refactor(audio-manager):=20=E2=99=BB?= =?UTF-8?q?=EF=B8=8F=20Replace=20direct=20signal-to-SFX=20mapping=20with?= =?UTF-8?q?=20a=20table-based=20system=20in=20AudioManager=20to=20reduce?= =?UTF-8?q?=20code=20duplication?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Co-Authored-By: Lilith Autocommit --- .../engine/src/autoloads/audio_manager.gd | 182 +++++++----------- .../engine/tests/unit/test_audio_manager.gd | 16 ++ 2 files changed, 84 insertions(+), 114 deletions(-) diff --git a/src/game/engine/src/autoloads/audio_manager.gd b/src/game/engine/src/autoloads/audio_manager.gd index ff0bd71d..c2345777 100644 --- a/src/game/engine/src/autoloads/audio_manager.gd +++ b/src/game/engine/src/autoloads/audio_manager.gd @@ -189,32 +189,51 @@ func stop_music() -> void: # --------------------------------------------------------------------------- +## Maps an EventBus signal name → SFX manifest key.
