# Plan Review — Step 2

Verdict: CHANGES REQUESTED

## Findings

### P1 — Pin the default-base clock and exact offset bounds before coding
The revised plan now calls out athlete-local `AddDate` arithmetic, but it still leaves important deterministic behavior unspecified: how the default `base_date` is derived and what “bounded unique integer offsets” means. Step 2 should explicitly require an injected clock for the no-`base_date` path, conversion of that instant into the athlete timezone before taking `YYYY-MM-DD`, and concrete offset limits/count limits (including whether negative offsets are accepted or rejected).

Without those details, the implementation can easily use `time.Now()` directly, UTC date extraction, or inconsistent max ranges, and the requested current-day/timezone-boundary tests may be flaky or not strong enough to catch the original hallucination class.

### P2 — Finish pinning the strict input/output schema contract
R002 asked for the public contract before implementation. The current checklist names `base_date`, offsets, and some `_meta` fields, but it still does not state the exact argument names/defaults, `additionalProperties: false`, required response row fields (`offset_days`, `date`, `weekday`), or full `_meta` shape (for example `base_weekday` in addition to base date/timezone/version/count).

Because this is a new public tool with a committed schema snapshot, the plan should define those fields now so tests and snapshot review validate the intended deterministic surface instead of whatever shape happens to be implemented.

## Verification

- Read `PROMPT.md` and `STATUS.md`.
- Reviewed prior Step 2 plan review (`R002-plan-step2.md`) and the updated Step 2 checklist.
- Spot-checked existing registry/catalog and `get_today` clock/timezone patterns.
- No tests run; this was a plan review.
