Vertical-slice endpoints for the new agent harness conversation model (agent_harness_conversations/runs, replacing the legacy location/routeId coupling on ai_chat_conversations): - GET /harness-conversations - paginated list, needUserQuery=true adds a 30-char truncated latest query per conversation - PATCH /harness-conversations/:conversationId - rename - DELETE /harness-conversations/:conversationId - delete - POST /harness-conversations/message - send a message; omitting conversationId creates a new conversation + run and enqueues HARNESS_START_JOB (reuses enqueueHarnessStart); rejects with 409 if the target conversation already has a run in progress Status shown to the user is resolved live from the Redis run snapshot (harness:run:<runId>:snapshot) while a run is in flight, falling back to the conversation's DB status once idle/terminal - the DB status only flips on terminal events so it lags mid-run. Perf hardening for high concurrency on constrained (1 vCPU/1GB) pods: - list's status resolution is now batched (RedisService.getActiveRuns/ getSnapshots via MGET) instead of up to 2 Redis round trips per row - list cache invalidation on mutations uses an O(1) per-user version counter (cacheVersion.ts) instead of deleteCacheKeysByPattern, which runs Redis KEYS - an O(N) full-keyspace scan that blocks Redis's single thread - the post-mutation status refresh query only runs on a cache hit, not after a fresh DB build that already has current statuses Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
