Gives agents a playbook for Debezium connectors whose status never becomes healthy: task states, database log positions, and bounded waits. Use when an agent waits on connector status past its timeout. Not for connectors that fail fast.
Fixes the agent applying D1 migrations to the local database when it meant remote, because the --remote flag was dropped. Use when local and remote schemas diverge after an agent migration run. Not for migration SQL errors or journal conflicts.
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.
