# Plan Review R002 — Step 1

**Verdict:** APPROVE

The updated Step 1 plan addresses the R001 blockers: it chooses a shared `internal/response` helper, derives all four fields from one localized instant, reuses the existing timezone-loading behavior, preserves invalid-zone errors vs empty-zone UTC behavior, and commits to deterministic clock injection for later current-day range checks.

Implementation notes to keep in mind:

1. If the helper is exported from `internal/response`, add doc comments for any exported function/type.
2. Ensure the returned `timezone` is the zone actually used for localization, especially `UTC` when the input is empty/whitespace, so metadata cannot contain an empty timezone while dates were computed in UTC.
3. When replacing `athleteLocalDate`, keep `get_today`'s current `date` semantics unchanged until Step 2 adds the new `_meta.as_of*` fields.

No further plan changes required before implementation.
