Cap the site backend's resources and document manual record lookups - #309
Conversation
A stray `docker exec` search for a nonexistent province.db ran in the production backend for 50 hours at a full core. The backend had no CPU, memory or process limits. Give both sites' backends caps well above normal use, and say in the PostgreSQL ops doc where site records live and how to query them. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
