Commits `8e21f48a1` + `0c7dbb7d6`. **BUT bullet 6's "visible *in the playable game*" is NOT yet met:** a discriminating probe (`test_emergence_probe.gd`, emergence-only, no seeding) found the live engine produces **0 populated tiles over 60 turns** — the live game never seeds fauna (`EcologyInitializer` is dead code) and emergence draws from `species_library`, which the live path left empty (`register_species` fills only the registry). Fixed the empty-library half this commit (new `GdFaunaEcology::load_species_library_from_json`, wired in `EcologyState._ensure_species_registered`), but emergence still didn't bootstrap on a synthetic flora-less grid — `check_emergence` gates on trophic structure (herbivores need vegetation). Both the renderer and the seeded data prove the render path; the world being *alive in real play* now hinges on the live-population fix below. Tracked as a follow-up (live fauna bootstrapping: initial seeding and/or emergence-on-real-worldgen verification). - ◻ `cargo test` green (incl. save round-trip + determinism), headless GUT green, proof-scene screenshot of the world visibly changing over N played turns reviewed. *(Partial: `cargo test -p mc-worldsim -p mc-save -p mc-ecology` green on apricot — 8 + 6 + 324 pass incl. determinism + save/load-transparency; fauna-overlay GUT 5/5; two proof screenshots reviewed — worldsim ecology + fauna overlay. Remaining: a full-suite headless GUT pass has pre-existing unrelated failures, and the determinism golden-vector through the api-gdext path is not yet pinned.)* ## Non-goals diff --git a/src/game/engine/src/autoloads/ecology_state.gd b/src/game/engine/src/autoloads/ecology_state.gd index 8bcf3a8d..a46b7278 100644 --- a/src/game/engine/src/autoloads/ecology_state.gd +++ b/src/game/engine/src/autoloads/ecology_state.gd @@ -70,12 +70,19 @@ func _ensure_species_registered() -> void: return dir.list_dir_begin() var registered_count: int = 0 + # Accumulate raw JSON so we can ALSO populate the engine's emergence library + # (the pool procedural emergence draws colonizers from).
