Serialize migrations on a direct Postgres connection and block deployment when migration setup or execution fails. Preview and local builds skip production migrations.
Remove the global Clerk loading gate that left public pages hanging when auth failed. Keep a stable guest key and preserve browser saves while identity resolves.
Run migrations for each Vercel preview as well as production. Reject mismatched runtime and migration database targets so schema changes cannot silently land on a different branch.

Public brackets now remain usable when Clerk fails or is slow to initialize. Removing the global auth-loading gate fixes the infinite “Loading bracket…” screen; a stable guest state key preserves typed input when guest auth finishes. Browser saves remain scoped by account. New Chromium and Firefox tests cover blocked Clerk scripts and delayed initialization.
Production and preview deployments now apply committed Drizzle migrations automatically before the Next.js build. Vercel's versioned build command runs the package build script, which invokes the deployment migration runner. Missing direct connection credentials or a failed migration stops the build.
A PostgreSQL session advisory lock serializes concurrent migration attempts on one direct connection. Drizzle's migration ledger makes retries idempotent; errors do not print connection details. Each preview migrates its own integration-provided database branch; local builds skip deployment migrations. The runtime and migration URLs must target the same database.
Set both
DATABASE_URL(pooled) andDATABASE_URL_UNPOOLED(direct) in Vercel Production using Neon'smainbranch. No manual deployment migration is needed. Configure both URLs for each preview through the Neon integration. Schema changes must remain compatible with the running app because migrations precede traffic switching; deployment rollback does not reverse schema changes.Validation: production build, lint (no new warnings), and all twelve migration/storage/unit tests passed against the isolated Neon development branch. CI also tests concurrent migration runners against a fresh Postgres service before running ownership and sharing tests. Production credentials and hosting settings remain user-managed.
Preview storage fix: confirmed the top preview was missing
account_bracketsand applied the schema to that isolated branch. All twelve migration/storage tests pass, including preview-mode migration and rejection of mismatched connection targets.
