fix(api_server): persist ResponseStore to SQLite across restarts#2472
Conversation
The /v1/responses endpoint used an in-memory OrderedDict that lost all conversation state on gateway restart. Replace with SQLite-backed storage at ~/.hermes/response_store.db. - Responses and conversation name mappings survive restarts - Same LRU eviction behavior (configurable max_size) - WAL mode for concurrent read performance - Falls back to in-memory SQLite if disk path unavailable - Conversation name→response_id mapping moved into the store

Summary
The
/v1/responsesendpoint used an in-memoryOrderedDictthat lost all conversation state on gateway restart. Users on platforms with hibernating VMs or frequent restarts lost multi-turn context entirely.Fix: Replace the in-memory store with SQLite at
~/.hermes/response_store.db.What changed
ResponseStorenow backed by SQLite with WAL modemax_size, default 100)Why not a new endpoint
PR #2437 proposed adding a separate
/v1/messageendpoint to solve this. Making the existing endpoint persistent is simpler and avoids API surface sprawl.Test plan
