+# Credits and Provenance
+
+Gig Line is a local, single-player security-shift game built with Godot 4 and
+GDScript. This file records the asset provenance needed for the release review;
+it is not a legal opinion or a claim that every provider licence has already
+been cleared for public distribution.
+
+## Game, code and design
+
+- Game design, systems, scenarios, dialogue and UI code: the Gig Line project.
+- Engine: [Godot Engine 4.7.2](https://godotengine.org/), MIT licence.
+- The game bundles no third-party fonts; it uses Godot's default theme font.
+- No third-party music, sound effects or voice recordings are bundled. Crowd
+  ambience and radio cues are generated procedurally at runtime.
+
+## 3D characters, gear and props
+
+The character, gear and prop library is generated by project-owned scripts
+(`tools/blender_assets.py`, `tools/npc_pipeline.py`, `tools/model_pipeline.py`)
+using Blender. The `.blend` working sources are developer artifacts and are not
+shipped. The exported `.glb` files and baked AO maps are project assets; they do
+not embed third-party models or purchased asset packs.
+
+The venue geometry is authored procedurally in `src/game/world_builder.gd` as a
+stylized reconstruction. The Joke Shop is a fictional stand-in for the real
+Sunset Strip block; the game does not claim endorsement by, or an exact replica
+of, any real venue or tenant.
+
+## AI-assisted images
+
+Surface textures, skyline panoramas, UI art and concept references were produced
+with image-generation calls from the project's tooling. The default model slugs
+recorded in the source are:
+
+- `bytedance-seed/seedream-4.5` — `tools/generate_textures.py`
+- `openai/gpt-5-image-mini` — `tools/asset_pipeline.py`,
+  `tools/model_pipeline.py`, `tools/scene_concepts.py` and
+  `tools/screen_designs.py`
+- Judging/review calls use the model selected by `tools/openrouter_judge.py` and
+  are development-only; they do not ship in the game.
+
+The prompts and generation workflow live in those tools. Per-file generation
+metadata is not stored with every image, so the exact provider, model version and
+generation date of each committed bitmap cannot be reconstructed from the
+repository alone. Before a public 0.10.0 release, the provider terms and
+commercial-use/redistribution rights for those generated outputs must be
+reviewed and recorded. **This is a release blocker, not an assumed clearance.**
+
+Reference photographs linked from the venue documents are hosted on Wikimedia
+Commons and were used for proportion/material study only. They are not included
+in the game or its release packages. If any future derivative asset copies a
+reference more directly, its attribution and licence must be added here.
+
+## Audio
+
+All runtime audio is procedural (crowd bed, radio crackle and interface cues).
+There are no external audio files, so there is no separate music/SFX licence to
+clear. See `docs/accessibility.md` for caption and volume behaviour.
+
+## Third-party names
+
+The game is a work of fiction. Real place names and public references are used
+for orientation and satire/stand-in geography; no real person, venue or brand
+endorses the game. Review the storefront and trademark language before release.
