# Side-Effects Review — Attention API vocabulary compatibility

**Version / slug:** `attention-api-vocabulary-compatibility`
**Date:** `2026-05-29`
**Author:** `instar-codey`
**Second-pass reviewer:** `self-audit; subagent not spawned by tool policy`

## Summary of the change

This change adds a route-boundary normalizer for Attention Queue status and
priority vocabulary. Canonical read/store values stay uppercase, while write
requests may use documented aliases such as `resolved`, `medium`, `body`, and
`source`. Generated guidance is also corrected to show the required stable item
id. Files touched include `src/server/attentionApi.ts`, `src/server/routes.ts`,
the generated guidance templates, and unit/integration/e2e tests.

## Decision-point inventory

- `PATCH /attention/:id` — modified — accepts documented aliases before calling
  the existing status updater.
- `GET /attention?status=...` — modified — accepts status aliases for filtering.
- `POST /attention` — modified — accepts documented create-field aliases before
  the existing tone-gated create path.
- Attention topic-flood guard — pass-through — no threshold, coalescing, or
  topic creation behavior is changed.

## 1. Over-block

The change reduces rejection of legitimate documented request shapes. It does
not add new block conditions. Unknown statuses and priorities still reject on
write, which is appropriate because the server cannot safely infer arbitrary
lifecycle states.

---

## 2. Under-block

The alias layer broadens accepted write vocabulary. The main residual risk is an
operator using an ambiguous word outside the alias set; those values still
reject. The accepted aliases map only to existing canonical values, so no new
state can bypass lifecycle handling.

---

## 3. Level-of-abstraction fit

The fix belongs at the HTTP route boundary. Internal storage and Telegram topic
commands already use canonical statuses; external callers and generated
guidance use friendlier names. Normalizing at the boundary preserves internal
consistency without forcing every caller to know storage vocabulary.

## 4. Signal vs authority compliance

**Required reference:** [docs/signal-vs-authority.md](../../docs/signal-vs-authority.md)

- [ ] No — this change produces a signal consumed by an existing smart gate.
- [ ] No — this change has no block/allow surface.
- [x] Yes — but this is hard-invariant API validation over a finite enum.
- [ ] Yes, with brittle logic — STOP. Reshape the design.

This is not a judgment gate. The route validates and normalizes finite API enum
values, which is one of the hard-invariant validation cases allowed by the
principle. It does not inspect message meaning or add a new block authority.

---

## 5. Interactions

- **Shadowing:** The normalizer runs before existing `updateAttentionStatus` and
  `createAttentionItem` calls. Canonical values pass through unchanged.
- **Double-fire:** No additional Telegram send, topic creation, callback, or
  persistence path is added.
- **Races:** No shared mutable state is introduced; normalization is pure.
- **Feedback loops:** Internal release-readiness resolution calls that already
  send `resolved` now work against the route instead of failing.

---

## 6. External surfaces

The `/attention` write surface becomes more permissive for documented aliases.
The read surface remains canonical uppercase. Generated AGENTS/CLAUDE guidance
will include a stable `id` in new installs and migrations. No existing attention
state is rewritten. No new attention items are created by the verification path.

---

## 7. Rollback cost

Rollback is a normal hot-fix revert. There is no data migration. If reverted,
documented lowercase resolve calls and create aliases would fail again until a
replacement patch lands.

---

## Conclusion

The fix aligns the documented write vocabulary with the canonical read/store
vocabulary without changing topic creation policy or existing state. The
three-tier tests cover the compatibility path and keep the topic-facing effects
stubbed during verification.

---

## Second-pass review (if required)

**Reviewer:** `self-audit; subagent not spawned by tool policy`
**Independent read of the artifact: concur**

The compatibility layer is intentionally limited to finite enum and field-name
aliases. It does not create automatic item ids, because stable ids are part of
the queue's dedupe discipline; the docs now show that requirement explicitly.

---

## Evidence pointers

- Read-only live inspection found 9 existing attention items using statuses
  `OPEN` and `DONE`, priorities `HIGH` and `NORMAL`, and no suppressed-topic log
  present.
