# v0.3 Dogfood Findings

TP-029 validates the v0.3 write/delete surface against a dedicated test athlete. All committed findings are redacted: no API keys, full athlete IDs, raw activity/event/workout/custom-item IDs, private comments, real thresholds, or complete tool payloads.

## Environment

- Credential source: `.env-dev` maintained out-of-band by the maintainer.
- Test athlete: redacted prefix recorded only in `STATUS.md`.
- Production-account guard: `.env-dev` athlete was compared against the maintainer's primary `.env` athlete without printing either value; they differ.
- Local binary: `bin/icuvisor` rebuilt from the lane before the dogfood run.
- Client: Codex CLI via MCP stdio, `--ephemeral`, with only env var names passed in MCP config.

## Safe-mode write subset

Mode: `ICUVISOR_DELETE_MODE=safe`.

### Cleanup / account state

- Calendar cleanup: PASS. The original TP-029 structured event and the two full-mode range-delete events were absent after verification scans.
- Non-TP-029 data: left untouched by the full-mode destructive run.
- Workout/custom-item cleanup: no cleanup required because W-10 and W-12 failed before creating durable objects.
- Wellness cleanup: no cleanup required because W-06 failed and W-07 avoided partial mutation.
- Sport-settings cleanup: the W-08 threshold-only Ride update was accepted and could not be automatically restored because committed records do not include the raw prior threshold. This is acceptable only because the credentials are for the dedicated disposable test athlete; before any future dogfood on a non-disposable account, capture a redacted restore plan out-of-band and avoid committing raw thresholds.

### Response-size caveat

Codex's final dogfood transcript did not expose per-tool raw response byte counts or token counts, and raw MCP payloads were intentionally not persisted to avoid committing account data. The findings table records this as `Unavailable` rather than fabricating measurements. Future dogfood should add a redacting MCP proxy or client-side byte counter so KR5-style per-tool byte/token sizes can be captured without storing raw payloads.

## Follow-up issues opened

All failures that blocked a required v0.3 dogfood path were filed under the `v0.3-followup` milestone:

- #6 — `add_or_update_event` NOTE create refused during dogfood.
- #7 — `update_wellness` subjective write refused during dogfood.
- #8 — `update_wellness` schema lacks `spO2` write field.
- #9 — `create_workout` refused during dogfood.
- #10 — `create_custom_item` validation rejected INPUT_FIELD dogfood item.

## v0.4 entry triage decision

### Launch-blocking before v0.4 entry

These findings block treating the v0.3 write catalog as ready for v0.4 entry because they affect required write paths or PRD-required writable fields:

- #6 — `add_or_update_event` NOTE create refused.
- #7 — `update_wellness` subjective write refused.
- #8 — `update_wellness` missing `spO2` schema field.
- #9 — `create_workout` refused.
- #10 — `create_custom_item` validation rejected the documented INPUT_FIELD case.

### Follow-up / seeded-data requirements, not launch blockers by themselves

- `link_activity_to_event`, `add_activity_message`, `delete_activity`, and `delete_gear` need a seeded disposable activity/gear fixture in the test athlete before they can be safely validated end-to-end.
- `apply_training_plan` needs a seeded disposable training plan/folder before dry-run/apply can be validated end-to-end.
- Per-tool byte/token measurement needs a redacting MCP proxy or client-side byte counter; this is useful for v0.4 token-efficiency work but did not invalidate the v0.3 safety findings.
