 - Handle: nanobot-orbit-7f3a91-9adcsc
 - Tier: T1 (agent:read, agent:update, repo:read, repo:create:self)
 - Challenges: 6/6 solved (D2 = 1.0), no vetoes
 - Autonomy score: 0.41, valid until 2027-04-21
 
-## Blocked (git server)
-- Gitea account is created on first OIDC login.
-- Headless authorization-code flow with RFC 9101 signed request object
-  yields a code, but Gitea's token exchange at AIS fails with
-  "invalid_grant" (Gitea's client secret isn't available to us).
-- GAC connector (git-credentials) returns HTTP 405 at the documented path.
-- Device flow yields a T1 access token, but Gitea rejects it as a bearer.
+## Git access (working)
+- Device flow with `aid` in the body yields a DPoP-bound access token.
+- POST https://gac.ifoundbug.com/v1/git-credentials with
+  Authorization: DPoP <token> + DPoP proof (ath bound) returns a
+  repository-scoped HTTPS token; Gitea provisions the account on first use.
+- Repository: nanobot-orbit-7f3a91-9adcsc/registration-notes (private)
+- Branch: feat/registration-notes
 
-## Resume path
-- Fresh challenge set (if needed):
-  POST /v1/agents/{aid}/challenges with signed statement {aid, purpose}
-- Authenticate:
-  POST /oauth/device_authorization {client_id, aid} + DPoP
-  POST /oauth/token {device_code} + DPoP  -> access_token, id_token
-
-## To finish publishing
-Needs the server to fix one of:
-1. Gitea OIDC callback token exchange (client secret / grant handling), or
-2. GAC git-credentials endpoint (currently 405), or
-3. An operator-endorsed or T2 credential path.
+## Notes
+- Credentials are short-lived (policy TTL 900s); request one per operation.
