## Access

Fetch the pinned repository, verify this source checksum, and use upstream installation and invocation. This record does not install or execute code.

Optional inert file retrieval: `python /PATH_TO_SKILL/scripts/rsh.py fetch-source habitat-lab-examples-hitl-basic-viewer-basic-viewer-py --expected-source-revision 0fb6f43ffe806a8088a171b036336c093bcf604e --expected-source-sha256 e58585c82f094992f489fb1d2639de277122084848127ac6ea0912eb63656e94 --project ./experiment --json`. This verifies one file, preserves provenance and never installs or runs it. See [source-file retrieval](https://hub.superfastrobotics.com/source-files.md).

Hub preparation adapter: **false**. Runtime verification: **not_run**.

## Requirements

```json
{
  "python": "Inspect the pinned upstream package metadata for the supported Python version.",
  "packages": [],
  "display": "Upstream simulator, robot model, build, display and device requirements; inspect the selected source.",
  "execution_domain": "simulation-or-hardware",
  "source_imports": [
    "habitat_hitl.app_states.app_service",
    "habitat_hitl.app_states.app_state_abc",
    "habitat_hitl.core.hitl_main",
    "habitat_hitl.core.hydra_utils",
    "habitat_hitl.core.key_mapping",
    "habitat_hitl.core.text_drawer",
    "habitat_hitl.environment.camera_helper",
    "hydra",
    "magnum"
  ]
}
```

## Invocation

```json
{
  "entrypoint": "python examples/hitl/basic_viewer/basic_viewer.py",
  "notes": "Source reference only. Install the pinned upstream project and its stated dependencies explicitly. Robot bridges may actuate hardware; no hardware execution is established. Asset, model, SDK and data terms remain separate."
}
```

## Compatibility

```json
[]
```

Missing environment fields remain unknown. Source discovery labels do not establish robot compatibility.

## Evidence

Level: **source_reviewed**. Runtime verification: **not_run**.

Fetched and SHA-256 checked this immutable source; statically parsed Python or located native main; verified pinned license bytes and checked explicit per-file license identifiers. No upstream code executed.

Source review and contributor reports do not establish task completion. Preserve upstream attribution and licenses.
