Debug Repo Mirror Issue with Store Refactoring

Traced it end-to-end. Here's the chain.

The message is server-side, not a CLI bug

(re)link your GitHub account to continue is not in the CLI repo. It's emitted by the EntireDB backend and passed through verbatim by entire repo mirror create.

The path:

1. CLI — repo_mirror.go:140 CreateMirror POSTs the placement request to the cluster.
2. Server — CreateMirrorPlacement → authorizeUserMirrorCreate (core/api/mirror_project.go:49).
3. Your upstream is github.com/**entirehq**/entire.io. entirehq is a GitHub org, so it takes the AccountTypeOrganization branch → requireRepoAdmin(ctx, claims, "entirehq", "entire.io") (mirror_project.go:65).
4. requireRepoAdmin → IsRepoAdmin → resolve(ctx, account) (adminchecker.go:160), which needs your personal GitHub login + a fresh access token to run the live admin check.
5. resolve fails and collapses to ErrGitHubLinkRequired for one of three reasons (adminchecker.go:160-176):
   • no github handle on your Entire account (identity.ErrNotFound)
   • no stored OAuth credential (githubtokens.ErrNotLinked)
   • GitHub rejected your refresh token (githubtokens.ErrRefreshRevoked)
6. mirrorAdminCheckError sees IsGitHubLinkRequired(err) == true and returns HTTP 401 with Message: "(re)link your GitHub account to continue" (mirror_project.go:173-177).

What it actually means

You are logged into Entire (otherwise the request would 401 at the session gate before reaching this). The Entire account behind your active auth context has no usable GitHub link — so the server can't run the org-repo admin check that mirroring entirehq/entire.io requires. Mirroring an org repo demands a live GitHub repo-admin verdict using your personal token; mirroring your own user repo wouldn't hit this path.

To resolve / diagnose further

• Fix: re-link GitHub for the active account (the OAuth link flow at entire.io, or whatever your re-link command is). After that, the admin check can run.
• Which of the three conditions tripped is deliberately collapsed in the user-facing message. To distinguish them you'd look at the server logs — but note resolve only logs for other errors; the link-required branches return silently. The fastest client-side check: confirm which account entire auth status reports, then verify that account has a GitHub identity linked.

Want me to check your active auth context / which account is in play (entire auth status), or look at how the CLI renders this 401 to confirm nothing is being swallowed on the client side?
