# Plan Review: Step 4 — Docs and verification

## Verdict: Approve

The Step 4 plan now addresses the gaps from R010 and is specific enough to execute.

## Notes

- The documentation target is correctly identified as the `get_wellness_data` registry/schema wording, with generated docs refreshed via `make docs-tools` when that source wording changes. This avoids hand-editing generated reference output.
- The plan preserves the separation between canonical response scale metadata (`_meta.scales.sleepScore`) and provider-native provenance labels (`_meta.provenance.<field>.native_scale`), which is central to the task.
- The changelog entry is scoped to a concrete user-visible response-shape/semantics change, including supported providers and the `unknown` fallback.
- Verification is explicit: run and record `make test`, `make build`, and `make lint`, while acknowledging Step 5 will repeat task-level gates.

## Implementation reminders

- If changing tool descriptions or output schema text, run `make docs-tools` and include the resulting `web/data/tools.json` change rather than editing `web/content/reference/tools.md` manually.
- Record exact command outcomes in `STATUS.md`, including any failures and whether they are fixed or pre-existing/unrelated.
