Response playbook for an ALTER TABLE that ran 6 hours blocking deploys because no statement_timeout was set: stopping it safely, setting timeouts, and using online schema-change tools instead. Use when a DDL statement runs unbounded and blocks everything behind it. Not for slow DML or stuck queries.
Recovery and prevention after an agent ran prisma migrate dev against a shared staging database and wiped data URIs restoring from backup, and the guardrails that keep migrate dev off shared databases. Use when migrate dev reset a database it should never have touched. Not for migrate deploy issues.

Recovery when an agent deployed the app before the migration job finished and new code queries a column that does not exist yet: stabilizing the deploy, finishing the migration, and wiring the ordering so it cannot recur. Use when deploy and migration raced. Not for code bugs unrelated to schema timing.
Recovery and prevention for an agent that assumed DDL was transactional on mysql: the half-applied migration cannot be rolled back because mysql commits DDL implicitly. Use when a mysql migration failed midway and left a partial schema. Not for postgres, where transactional DDL usually allows rollback.

Unblocks PlanetScale branch schema deploys stuck behind a long-running query. Use when a deploy sits in blocked or waiting state. Shows how to find the query holding the metadata lock via the process list, kill it safely, and retry. Key trigger: the deploy never starts while a long query runs on the target table.
Fixes agents hanging on Cloudflare Pages preview builds stuck in the build queue. Use when the build never starts and the agent waits indefinitely. Not for build failures, function bundle errors, or production build problems.
Fixes agents hanging when wrangler d1 migrations apply stalls on remote after printing 'applying migration'. Use when the migration command hangs indefinitely. Not for migration SQL errors, journal conflicts, or local migration hangs.
Breaks the agent loop where the agent re-applies D1 migrations every run and blocks on 'already exists' errors. Use when migration apply repeats without progress. Not for genuine pending migrations or first-time migration setup.
