# Code Review: Step 4 — Tests and docs

## Verdict

Approve.

## Findings

No blocking findings.

## Notes

- The fixture-backed public-tool test now covers structured intervals, 1 km auto-laps, 1 mi auto-laps, and unknown source through `get_activity_intervals`, and asserts both `_meta.interval_source` and `_meta.auto_lap_suspected` in default terse mode.
- The docs/changelog updates describe the additive metadata and analyzer caution without changing the generated tool catalog source.
- Minor bookkeeping: `STATUS.md` lists R010's file as `inline`, but this change also adds `.reviews/R010-plan-step4.md`. This is not a code blocker, but it would be cleaner to point the table at the file.

## Verification

Ran:

- `go test ./internal/tools ./internal/analysis`
- `make test`
- `make build`
- `make lint`

All passed.
