 7. Select `https://db.vrdex.net` as the production deployment's canonical `CONVEX_SITE_URL`.
 8. Rerun production auth smoke checks from `https://vrdex.net/sign-in`.
 
 Current production status: `db.vrdex.net` is configured and verified for the production deployment, Google and Discord allow the new callback URLs, production `CONVEX_SITE_URL` is selected as `https://db.vrdex.net`, and Google and Discord sign-in from `https://vrdex.net/sign-in` return to an authenticated `/account` session.
 
+## Legacy OAuth Callback Retention
+
+Current recommendation: keep the legacy `.convex.site` OAuth callback URLs configured as provider fallbacks for now.
+
+- staging fallback callbacks: `https://scrupulous-corgi-247.convex.site/api/auth/callback/...`
+- production fallback callbacks: `https://superb-pig-954.convex.site/api/auth/callback/...`
+
+Do not remove those provider callback URLs in the same change that enables or documents a custom Convex Auth callback host. Revisit removal only after the custom hosts have stayed stable through scheduled deployed health checks and at least one manual OAuth callback recheck per provider after any Auth, Convex custom-domain, or provider-app change.
+
+Earliest removal-review target: 2026-07-06, assuming production and staging auth health remains green.

 ## Notes
 
 Resolved 2026-06-15: the duplicate Convex project `vrdex-85631` was deleted after confirming the active project is `vrdex`, the duplicate deployments had no env variables or custom domains, and their `profiles` tables were empty.

 - Discord sign-in from `https://vrdex.net/sign-in` returns to an authenticated `https://vrdex.net/account` session.
 - Convex production includes `JWT_PRIVATE_KEY` and matching `JWKS`, required for Convex Auth to mint web session cookies after OAuth callbacks.
 
+### Production authenticated account smoke
+
+The `Deployed Health Checks` workflow always runs a production read-only route smoke when `VRDEX_PRODUCTION_SMOKE_BASE_URL` or a deployment status URL is available. It can also run a gated authenticated account smoke when a safe production test-account path exists.
+
+Repository settings for the authenticated lane:
+
+- variable `VRDEX_PRODUCTION_SMOKE_BASE_URL=https://vrdex.net`: required so auth cookies target the stable public domain instead of a generated Vercel deployment URL
+- optional variable `VRDEX_PRODUCTION_AUTH_SMOKE_PROVIDER`: expected linked provider, usually `discord` or `google`; if unset, the smoke accepts either provider
+- secret `VRDEX_PRODUCTION_AUTH_SMOKE_STORAGE_STATE_B64`: base64-encoded Playwright `storageState` JSON from a dedicated production test account that has completed OAuth sign-in
+
+This smoke does not enable production E2E helpers, does not mutate data, and does not store OAuth provider passwords in CI. It checks that the pre-authenticated production account can load `/account`, sees a sign-out control, and has at least one linked OAuth provider. Refresh the storage-state secret by manually signing in as the dedicated test account and exporting Playwright storage state before the session expires or after OAuth/provider/callback changes.
+
+This lane validates the signed-in production account path and linked-provider rendering. It is not a full automated provider-login robot; provider credential entry and fresh OAuth consent should remain manual or use a provider-approved non-interactive test-account mechanism.
+
 ## Validation
 
 The Vercel build runs `pnpm build:vercel`, which executes `apps/web/scripts/check-vercel-env.mjs` before `next build`.
