 - **fix(usage):** the z.ai/GLM coding-plan quota card no longer shows "Monthly 0%" — coding plans have no monthly cap (only 5-hour windows), so the quota API reports the `TIME_LIMIT` ("Monthly") entry with `total=0`, and the `total>0 ? … : 0` fallback rendered a misleading 0% remaining (which can skew downstream model-choice). With no absolute cap the remaining percentage now falls back to the percentage-derived value (full/100% when 0% used). ([#3580](https://github.com/diegosouzapw/OmniRoute/issues/3580))
 - **docs(discovery):** mark `DISCOVERY_TOOL_DESIGN.md`'s API Endpoints table with an explicit "⚠️ Not yet implemented — Phase 2" banner — the discovery routes are a design proposal (Phase-1 stub only), and the banner makes clear the `KNOWN_STALE_DOC_REFS` gate suppression is intentional, not stale drift. ([#3498](https://github.com/diegosouzapw/OmniRoute/issues/3498))
 - **fix(agent-bridge):** add the missing `POST /api/tools/agent-bridge/upstream-ca/test` route — the UpstreamCaField "Test" button POSTed to it but it didn't exist (404). The new validate-only route checks the CA file exists and is a parseable PEM certificate (returns the subject/expiry) **without** persisting the path or activating it; it inherits the `/api/tools/agent-bridge/` LOCAL_ONLY classification. ([#3488](https://github.com/diegosouzapw/OmniRoute/issues/3488))
+- **fix(gamification):** the dashboard Profile page no longer hits three 404s — added the missing `GET /api/gamification/{level,badges,badges/earned}` routes (management-scoped). The page is operator-wide (no `apiKeyId`), so `level`/`badges/earned` aggregate across all keys (with an optional `?apiKeyId` for a single key), and `badges` seeds the built-in catalog first (idempotent) so the grid is populated even on installs that never seeded it (see #3472). ([#3484](https://github.com/diegosouzapw/OmniRoute/issues/3484))
