# Code Review R011 — Step 4: Resolve Conflict C (`update_wellness` error contract)

Result: APPROVE

## Findings

No blocking findings.

## Notes

- Reviewed `git diff 1487b3d95da44432f63d9ad108ed65912fe2cfa0..HEAD`; the committed Step 4 delta only updates `STATUS.md` with the verification/resolution notes for Conflict C and the prior plan-review log entry.
- Independently checked the cited sources:
  - `docs/prd/PRD-icuvisor.md:252` documents both exact read-only field errors.
  - `internal/tools/update_wellness.go` returns `field_not_writable: sleepScore (device-managed)` and `field_not_writable: _native (bridge-managed)`, and treats those literals as user-facing validation messages.
  - `web/data/tools.json` includes both literals in the generated `update_wellness` summary rendered by `web/content/reference/tools.md`.
  - `README.md` is currently a slim pointer to the website catalog and has no stale per-tool `update_wellness` text to update.

The Step 4 status entry accurately records the current tree and does not introduce an inconsistency.
