 The forums Prisma schema defines `Topic`, `Post`, `PostReaction`, `TopicClosure`, `TopicWatch`, `TopicReadState`, `MemberBan`, and `IpBan` in the dedicated `forums` schema. `PostReaction` uses a composite post/member key so each member has at most one thumbs-up or thumbs-down value per post; deleting a post cascades its reactions. Topics store an explicit lock state plus nullable lock timestamp and lock actor member id. Ban rows keep active and removed audit metadata; the migration enforces one active row per member or exact IP value and validates IP bans as single IPv4/IPv6 host values. `pnpm prisma:generate` emits the local client at `prisma/generated/client` and the reusable exported client at `packages/forums-prisma-client`.
 
+The production image includes the Prisma schema, migration history, configuration, and CLI. Its startup script runs `prisma migrate deploy` before starting NestJS, so a deployment cannot begin serving requests against an older forums schema. Migration failure stops the container instead of leaving feature-dependent reads or writes partially available.
+
 Topic creation is transactional: it creates the topic, starter post, closure rows, and, for human authors, author watch and read-state rows together. M2M topic creation uses the system author and skips member watch/read-state side effects. Topic deletion is soft deletion, and post deletion preserves the post row while setting content to null for placeholder reads. Topic summary reads use side-effect-free raw queries for topic lock state, visible-post counts, nullable latest visible activity, and unread derivation, then apply centralized forums policy filtering before pagination.
