Restore the credential guard around preview-only steps. The metadata assertion requests the fixed production URL in AUTHORIZATION_SERVER_METADATA_URL and does not consume either the Vercel deployment or steps.preview.outputs.endpoint. However, this change also removes if: steps.credential.outputs.available == 'true' from Wait for this commit's Vercel preview, Resolve Vercel preview endpoint, and Verify preview still belongs to this commit. When MCP_EVAL_TOKEN is unavailable, both matrix jobs now wait for and validate a Vercel preview even though the authenticated preview smoke is skipped; only the 2026-07-28 job then performs the independent production metadata check. A delayed deployment, missing Vercel status, or missing/churned bot comment can therefore fail CI for reasons unrelated to this assertion. Please restore the credential guard on those three preview-only steps so the production metadata assertion can run independently. Alternatively, if the preview is intended to be tested, use the resolved preview origin in the assertion.

Describe this as a production metadata check. CI no longer follows the preview deployment's metadata redirect: the workflow hard-codes https://mcp.terminal49.com/.well-known/oauth-authorization-server, so it follows the production deployment's redirect instead. Please describe this as a live/production metadata check, or change the workflow to request the resolved preview origin. As written, maintainers may incorrectly assume a PR's redirect handler and preview environment configuration are covered.

P2 Badge Correct the claim that CI checks the preview redirect

The workflow does not follow the preview deployment’s metadata redirect: .github/workflows/ci.yml hard-codes https://mcp.terminal49.com/.well-known/oauth-authorization-server. Consequently, a preview with a broken redirect or incorrect WorkOS issuer can still pass while production remains healthy, so this operational guide gives maintainers false assurance about what CI validates; describe this as a production metadata check or change the workflow to query the resolved preview origin.

P2 Correct the validated environment

This text says CI follows the preview deployment’s authorization-server redirect, but the workflow requests the fixed production mcp.terminal49.com URL. Maintainers can therefore mistake successful CI for evidence that preview-specific OAuth configuration advertises refresh support.

omits `offline_access`. These capabilities belong in the WorkOS authorization
server metadata, not the Terminal49 Protected Resource Metadata (PRM).

### Human refresh smoke

Refresh requires a real user authorization. Do not store a user password in CI.
Run the local [OAuth test client](./OAUTH_TEST_CLIENT.md), which requests
`openid profile email offline_access` and registers both
`authorization_code` and `refresh_token` grant types.

1. Click **Authorize** and complete the WorkOS sign-in.
2. In the redacted token output, confirm the response contains a
`refresh_token` and the access token `aud` is
`https://mcp.terminal49.com`.
3. Click **Refresh**. The client posts `grant_type=refresh_token`, the current
refresh token, and `resource=https://mcp.terminal49.com` to the discovered
token endpoint using the same registered client.
4. Confirm the refreshed response contains a new `access_token` whose `aud`
is still `https://mcp.terminal49.com`.
5. Click **Tools List** and confirm `tools/list` succeeds with the refreshed
bearer token.
6. If WorkOS returns a replacement `refresh_token`, retain it for the next
refresh. The local test client does this automatically; it keeps the
previous refresh token only when the response omits a replacement.

The test client redacts tokens and client secrets in its browser output. Do not
copy credentials into CI output, shared shell history, or issue comments.
