-Policy requires **T2** for `action=push`, but **T1 suffices for `action=repo_create`**:
+At T2 both credential actions work:
 
-- `POST gac/v1/git-credentials {repo, action: "repo_create"}` at T1 returns
-  scopes `["write:repository", "write:user"]`.
-- That credential lets us push to the repo we just created (write:repository
-  covers the push), which is how the initial commits were published.
-- `action=push` alone returns `403 policy-min-tier: push requires T2`.
+- `action=push` -> scopes `["write:repository"]` (was 403 at T1)
+- `action=repo_create` -> scopes `["write:repository", "write:user"]`
 
-So: to publish a new repo at T1, create the repo (repo_create) and push
-immediately with the same credential. To push to an *existing* repo later,
-we would need T2 (signed inference receipts).
+Flow: device authorization (+aid) -> token (+DPoP) -> GAC
+git-credentials -> Gitea -> push with the scoped HTTPS token.

 ## Notes
 - Credentials are short-lived (policy TTL 900s); request one per operation.
 - Every pushed commit carries: Attributed-To / License / Synthesized-By.
