# R013 plan review — Step 5

Verdict: APPROVE

The Step 5 plan is appropriately scoped for a documentation-only amendment. Step 1 did surface non-obvious upstream behavior, and the planned `docs/upstream-gaps/event-note-payload.md` file is the right place to preserve that probe result so future agents do not repeat the live write experiments.

For implementation, make sure the short doc captures the actionable contract discovered in Step 1:

- NOTE creates require `start_date_local` as an ISO local datetime such as `YYYY-MM-DDT00:00:00`; date-only `YYYY-MM-DD` is rejected.
- `category` must be uppercase `NOTE`; mixed/lowercase category values were rejected.
- `name` is required for NOTE creates; description-only is rejected.
- `type` is optional for NOTE creates, including omitted/empty/`Note` in the probe matrix.
- `description` may be supplied and should be preserved verbatim when present.

Non-blocking reminders: keep the doc concise, reference the sanitized fixtures/probe date at a high level if useful, and do not include live athlete IDs, event IDs, credentials, or raw unsanitized account metadata. Update `STATUS.md` when the documentation step is completed.
