# TP-141: Running pace-zone unit and label audit — Status

**Current Step:** Step 4: Documentation & Delivery
**Status:** ✅ Complete
**Last Updated:** 2026-06-03
**Review Level:** 1
**Review Counter:** 3
**Iteration:** 1
**Size:** S

> **Hydration:** Checkboxes represent meaningful outcomes, not individual code changes. Workers expand steps when runtime discoveries warrant it — aim for 2-5 outcome-level items per step, not exhaustive implementation scripts.

---

### Step 0: Preflight
**Status:** ✅ Complete

- [x] Required files and paths exist
- [x] Dependencies satisfied
- [x] Confirm no GPL/copyleft competitor source is opened or copied; use only public forum behavior signals and project docs.

---

### Step 1: Audit run pace read/write coverage
**Status:** ✅ Complete

- [x] Inspect athlete-profile and sport-settings tests for threshold pace, pace units, and pace-zone names.
- [x] Confirm tests cover both `seconds_per_km` and `seconds_per_mile` inputs and upstream pace unit output.
- [x] Record any ambiguous LLM-facing wording or missing scale/unit metadata in STATUS.md.
- [x] Run targeted tests: `go test ./internal/tools ./internal/units`.

---

### Step 2: Add pace-zone regressions and wording fixes
**Status:** ✅ Complete

- [x] Add missing tests for Run threshold pace conversion and pace zone boundary/name round trips.
- [x] Update schema descriptions or response labels if they could be misread as speed rather than pace seconds per distance.
- [x] Ensure zone overwrite behavior remains gated by `ICUVISOR_DELETE_MODE=full` where applicable.
- [x] Run targeted tests: `go test ./internal/tools ./internal/units`.

---

### Step 3: Testing & Verification
**Status:** ✅ Complete

- [x] Run FULL test suite: `make test`
- [x] Run lint: `make lint`
- [x] Fix all failures or document pre-existing unrelated failures with exact command output
- [x] Build passes: `make build`

---

### Step 4: Documentation & Delivery
**Status:** ✅ Complete

- [x] "Must Update" docs modified
- [x] "Check If Affected" docs reviewed
- [x] Discoveries logged in STATUS.md

## Discoveries

| Date | Step | Finding | Impact |
|------|------|---------|--------|
| 2026-06-03 | Step 1 | Existing read tests cover MINS_KM and MINS_MILE output shaping, and write schema exposes seconds_per_km/seconds_per_mile, but update_sport_settings has a regression only for seconds_per_km input conversion. | Step 2 should add a seconds_per_mile input conversion regression. |
| 2026-06-03 | Step 1 | Response field names and athlete profile _meta.pace_convention are clear that pace values are seconds per distance; update_sport_settings zone boundary schema says "seconds in the sport pace unit" but does not explicitly say "not speed" or name seconds_per_km/seconds_per_mile examples. | Step 2 should tighten LLM-facing wording for pace-zone boundaries if changed tests touch schema wording. |
| 2026-06-03 | Step 4 | Reviewed PRD sport-settings and per-athlete unit-normalization sections; code changes only clarify existing schema wording and add regressions, with no material contract change. | PRD update not needed. |
