## Discoveries

| Discovery | Disposition | Location |
|-----------|-------------|----------|
| `make fmt-check`, targeted tests, `make test`, `make build`, and `make lint` passed for TP-104 verification. | Recorded as Step 5 evidence; no pre-existing failures encountered. | STATUS.md Step 5 |
| ROADMAP `_meta.as_of` item is fully satisfied by TP-104; generated tool docs had no diff after `make docs-tools`, and PRD product contract did not require changes. | ROADMAP checkbox updated; no generated docs or PRD edits needed. | ROADMAP.md / docs/prd/PRD-icuvisor.md / web/data/tools.json |

## Notes

- Tracking issue: https://github.com/ricardocabral/icuvisor/issues/31
- Step 1 plan: add a shared `internal/response.AsOfMetadata(now time.Time, timezone string)` helper returning one struct with `as_of`, `as_of_date`, `as_of_weekday`, and `timezone`, all derived from a single localized instant. The helper will reuse the existing timezone loading path used by `RenderTimeInTimezone`/`RenderDateInTimezone`; malformed zones return the existing wrapped load error and empty timezone continues to resolve to UTC. `get_today` keeps using its injectable `now func() time.Time`; Step 3 tools will receive injectable clock constructors before calling the helper/current-day range predicate, avoiding direct untestable `time.Now()` in handlers. Tests will cover positive/negative offset date shifts, weekday consistency, trimmed and empty timezone behavior, and invalid-zone errors.
- Step 2 plan: in `getTodayHandler`, call the injectable `now()` exactly once, pass that instant to `response.AsOfMetadataInTimezone`, use `asOf.AsOfDate` for the existing `today` fetch date, and pass the full helper result into `shapeGetTodayResponse` so `date` and `as_of_date` cannot diverge across midnight. Extend `getTodayMeta` with `as_of`, `as_of_date`, and `as_of_weekday` while preserving existing `date`, `timezone`, `include_full`, `source_tools`, `section_counts`, `activity_window`, and response-shaper-added metadata such as `units`. Populate `_meta.timezone` from the helper's trimmed/defaulted `Timezone`. Update `get_today` tests through `newGetTodayToolWithClock` to assert exact São Paulo boundary `as_of*` values and unchanged local-date fetches/counts, then run `go test ./internal/tools -run TestGetToday`.
- Step 3 plan: add a small tools-level helper that computes `response.AsOfMetadataInTimezone(now(), timezone)` once per request and attaches `as_of`, `as_of_date`, `as_of_weekday`, and helper-normalized `timezone` only when the normalized request date range includes `asOf.AsOfDate`; closed ranges require `oldest <= today <= newest`, and `get_activities` with blank `newest` treats the range as open-ended through upstream now. Add with-clock constructors for activities, events, and wellness so tests do not depend on wall-clock time. Preserve each tool's existing pagination token, count, null stripping, terse/full, and response-shaper metadata by only extending response meta structs immediately before shaping.
- Step 4 plan: rely on `TestAsOfMetadataInTimezone` for helper-level positive-offset Kiritimati and negative-offset São Paulo boundary coverage, and add/keep range-tool regressions for both include and exclude behavior. Activities already has current-day/open-ended include and past-only exclude assertions; add past-only exclude assertions for events and wellness that verify `as_of`, `as_of_date`, and `as_of_weekday` are absent while existing metadata (`timezone`, count/limit/truncated/date_range for events; oldest/newest/include_full and null stripping for wellness) remains intact. Update `CHANGELOG.md` under `[Unreleased]` `### Added` with the additive `_meta.as_of`, `_meta.as_of_date`, `_meta.as_of_weekday`, and `_meta.timezone` behavior for `get_today` and current-day `get_activities`, `get_events`, and `get_wellness_data`. Run `go test ./internal/response ./internal/tools -run 'TestAsOfMetadataInTimezone|TestCurrentDayAsOfMetadataRangePredicate|TestGetActivities.*AsOf|TestGetEvents.*AsOf|TestGetWellnessData.*AsOf'`.
- Step 5 plan: run targeted verification for all affected code with `go test ./internal/response ./internal/tools -run 'TestAsOfMetadataInTimezone|TestRender(Date|Time)InTimezone|TestCurrentDayAsOfMetadataRangePredicate|TestGetToday|TestGetActivities.*AsOf|TestGetEvents.*AsOf|TestGetWellnessData.*AsOf'`, then `make fmt-check`, `make test`, `make build`, and `make lint` in that order. Record each command's pass/fail in STATUS.md immediately after it completes; if any command fails, capture the exact command, relevant error, and whether a code fix was applied or evidence for an unrelated pre-existing failure. No generated tool-reference/docs refresh is expected because this task changes runtime response metadata descriptions/tests and `CHANGELOG.md`, not generated catalog data.
