Nav2 BT: To-pose replanning and recovery
Declares planning to a pose, following and contextual/general recovery. Static source reference only; no task, timing or robot behavior was tested.

Access
Inspect this checksum-pinned text in the full upstream checkout. Resolve adjacent definitions/assets and their separate licenses using upstream instructions. The Hub does not load or execute this artifact.
For one verified inert file, use the installed CLI's inspect response fetch_source_args and append --project DIR --json. Source-file retrieval creates no environment and does not install or run the source.
Hub preparation adapter: false. Follow the upstream setup and invocation contract.

- Apache-2.0
- License scope
- Exactly these otherwise-unmarked nav2_bt_navigator workflow XML texts. The selected package declares Apache-2.0 and the root index explicitly supplies that default for otherwise unmarked files. nav2_docking/LICENSE supplies complete standard terms only, not a grant or author attribution transferred from docking. Preserve applicable license, notices and modification obligations. No individual XML author is declared; the package maintainer is not inferred as author. Dependencies, node implementations, binaries, maps, assets and hardware retain their own terms.

"notes": "A complete configured upstream BT host loads this XML. Its action/service node implementations can command hardware; fetching this inert file does not load a host, validate ports or establish task success, timing, stopping or robot compatibility.

}Explicit compatibility
[]Missing environment fields remain unknown. Discovery labels do not establish robot compatibility.
Evidence
Level: source_reviewed; runtime verification: not_run.
Verified exact source and applicable license SHA-256 bytes. Inventoried one bounded BTCPP4 XML tree and parsed literal attributes. Node availability, ports, blackboard expressions, timing and runtime behavior were not evaluated.
Source review and contributor reports do not establish task completion. Preserve upstream attribution and licenses.
