This release provides recorded controls, cameras, observed world state, static map geometry, and frame correspondence data for studying paired videos and rendering alternative proxy styles. It covers 21 recording sessions. The training subset contains 5,000 selected paired clips; metadata retains the wider sessions and temporal context.
## Files and extraction
| Path | Contents |
| --- | --- |
| `episodes/episode_###.tar.gz` | Controls, cameras, world observations, timing, available Parquet tables, and proxy frame/scene metadata |
| `maps/scene_001.tar.gz` | Static placements, spatial databases, collision meshes, materials, and water |
| `source_index/global_index.sqlite3` | Portable frame, segment, source, and cross-view correspondence index |
| `renderer/proxy_source_5_5_1.zip` | Minimal renderer source package |
| `renderer/environment/requirements.lock` | Recorded Python dependency versions |
| `integrity/*.members.jsonl.gz` | SHA-256 and byte size of every archive member |
| `catalog.json` | Artifact sizes, hashes, and archive counts |
| `schema.json` | Main fields and timing conventions |
Extract recording and map archives under `source/`:
```bash
mkdir -p source
tar -xzf metadata/episodes/episode_001.tar.gz -C source
tar -xzf metadata/maps/scene_001.tar.gz -C source
```
This creates `source/recordings/episode_001/` and `source/worlds/scene_001/`. Database paths are relative to `source/`. Paths inside recording JSON are relative to the release root. Original long-form RGB/proxy videos and audio are omitted; their source identities and timing remain in the index, while selected videos are in the training archives.
Some preserved recording manifests still name historical validation reports or derived directory indices. Those diagnostic files are excluded from this public release. Use the released SQLite index, member integrity manifests, and JSONL observations for inspection and replay. Source video paths in the index are provenance references and are not expected to resolve to long-form media in this release.
## Controls, cameras, and world state
`recordings/<episode>/.spool/agents/<agent>/client.jsonl` is the authoritative client stream. Each row contains episode, agent, sample, frame, and clock identifiers, plus:
- `action`: movement/look axes; jump, sprint, crouch, interaction, vehicle entry/exit, primary/secondary controls, and available keyboard/mouse input. Button states distinguish `pressed`, `released`, and `held`.
- `camera`: rendered camera position, rotation, field of view, projection rays, clip planes, resolution, and frame counter.
- `agent_state`, `subject_observation`, and `scene_observation`: transforms, motion, appearance, coarse body observations, and nearby entities with availability/completeness flags.
`recordings/<episode>/.spool/world_state.jsonl` contains server observations: sample sequence, monotonic time, environment, agents, vehicles, pedestrians, objects, task state, relations, and lifecycle events. Preserve nulls and availability flags. Missing data does not imply zero or an absent entity.
Where available, `agents/<agent>/*.parquet` and `server/*.parquet` provide fixed identifier columns and a JSON `payload_json` column. Parquet is not present for every session; authoritative JSONL streams cover all 21.
## Timing and joins
Nanosecond fields use integer nanoseconds; `_ms` fields use milliseconds. Capture and simulation monotonic times remain available for joins. In-game environment time is retained. Collection wall-clock fields are omitted.
Processed clips preserve 124 frames at 24 FPS, nominally 5.1667 seconds. Per-clip alignments connect left/right output frames to numeric `frame_id` and source segment. In SQLite:
- `frames.frame_id` identifies an indexed source frame.
- `source_id` plus `rgb_decode_index` identifies an original source-video frame.
- `proxy_frame_index` selects the matching RGB/proxy frame within a segment.
- `world_capture_tick` and client sample identifiers connect frames to observations.
- `cross_view` records the nearest usable other-view frame in the same session and clock domain, with signed difference and a 75 ms threshold.
Cross-view correspondence is a clock estimate, not independent visual synchronization ground truth. Equal frame numbers do not imply matched views. `status=estimated_alignment` marks usable indexed frames; other statuses retain missing-data evidence.
## Map and proxy geometry
The map includes placements, static spatial SQLite data, heightmap, collision databases/indices, compressed triangle meshes, materials, and water geometry. GTA asset names and relative game-internal archive paths are retained as resource identifiers. Mesh records contain nine little-endian float32 values, one uint16 material, and one uint16 flags field, totaling 40 bytes.
GTA V and its game assets are third-party material. Their presence and resource names provide attribution and scientific context; this metadata documentation does not grant or invent a license for those assets.
Per-segment `scene_*.json` files record static scene selection and geometry policy. `frames.jsonl`, `source_frames.jsonl`, `source_alignment.jsonl`, `compiler_manifest.json`, and appearance records retain rendering/alignment details. Underlying world/version hashes are scientific identifiers; use the release member integrity manifests to verify rewritten public files.
## Public identifiers and exclusions
Sessions use `episode_001` through `episode_021`; the map uses `scene_001`. Server clock domains use consistent `clock_###` identifiers shared with training alignments. Other client/clock identifiers use stable pseudonyms. Numeric simulation, entity, frame, segment, and sample identifiers remain available for joins.
Public metadata removes collection wall-clock fields, workstation paths, machine/client UUID strings, authentication values, historical recovery manifests, incomplete sidecars, runtime logs, and operational documentation. This curated representation is not a byte-identical recording-directory export. The private identity map is not distributed. Archives are checked for known private identifiers and field patterns used by this pipeline; this is not a claim that all potentially identifying visual content has been removed.
## Scope and limitations
The observations and renderer support alternative proxy colors, geometry conventions, shading, and camera visualizations. Arbitrary new player actions require a simulator or learned dynamics model; recorded trajectories do not establish counterfactual world evolution.
The map is an exported installed scene and does not recover every recording's dynamic interior/map-layer state. World completeness depends on available observations. Human proxies primarily encode root motion/coarse orientation; missing articulation is not reconstructed. Source limitations include some log-pile geometry, roof/foot occlusion, barriers, and vegetation detail. Vehicle occupant smoothing changes display transforms while retaining observations.
See `docs/RENDERING.md` and the release examples for frame inspection and reconstruction.
