+### Phase 14.1: OAuth identities and fonoteka me routes (INSERTED)
+
+**Goal:** The three manifest routes no phase owned (14-CONTEXT D-09) are ported and pass the parity diff, so that no route is left `pending` before cutover. They are `GET /_fonoteka/api/v1/oauth-identities`, `DELETE /_fonoteka/api/v1/oauth-identities/{provider}` (social-login identities, deferred since Phase 7) and `GET /api/v1/fonoteka/me` (the full contract, not only the minimal Phase 8 D-20 version).
+**Mode:** mvp
+**Requirements**: TBD
+**Depends on:** Phase 14
+**Repos:** fonoteka.go (plus sm-user-plugin if the identities live in the user plugin)
+**Success Criteria** (what must be TRUE):
+
+  1. `GET oauth-identities` lists the signed-in user's linked social identities exactly as PHP returns them.
+  2. `DELETE oauth-identities/{provider}` unlinks one identity with PHP's status codes and error shapes.
+  3. `GET /api/v1/fonoteka/me` matches the PHP response for fonoteka-mcp token callers.
+  4. All three manifest entries flip from `pending` to ported with recorded PHP cases, leaving zero pending routes.

 ### Phase 15: Cutover
 
 **Goal**: The parity harness is green on all 154 routes and `vue-fonoteka-app` and `fonoteka-mcp` run unchanged against the Go backend in daily use — the project's definition of done.
