`SessionManager.close()` queues `#closePersistWriterInternal()` on the
persist chain. The task awaits `#persistWriter.close()`, which flips
`#closing = true` synchronously before yielding on its inner writer
`close()`. A concurrent `appendMessage()` landing in that yield window
hit the hot path, got the still-cached (but closing) writer back from
`#ensurePersistWriter()`, and threw `Error("Writer closed")` from
`writeSync`. The throw was stashed into `#persistError`; the next async
caller (`flush()` or a later `appendMessage()`) re-threw it as an
unhandled rejection with the original line-1282 stack.
Expose `NdjsonFileWriter.isOpen()` and treat a mid-close cached writer
as a miss in `#ensurePersistWriter()`. `_persist` now falls back to the
async `#rewriteFile()` cold path so the entry — already in
`#fileEntries` — still lands on disk once the close drains.

Memory backends
The agent supports three mutually-exclusive memory backends, selected via the memory.backend setting (Settings → Memory tab, or ~/.omp/config.yml):
off(default) — no memory subsystem runs.local— existing rollout-summarisation pipeline; writesmemory_summary.mdand consolidated artifacts under the agent dir.hindsight— talks to a Hindsight server (Cloud or self-hosted Docker), retains transcripts every Nth user turn, recalls memories on the first turn of a session, and exposesretain,recall, andreflect.
Hindsight quickstart
- Run a Hindsight server (Cloud or
docker run -p 8888:8888 ghcr.io/vectorize-io/hindsight:latest). - Set
memory.backend = "hindsight"andhindsight.apiUrl = "http://localhost:8888"(or your Cloud URL). - Optional environment overrides (env wins over settings):
HINDSIGHT_API_URL,HINDSIGHT_API_TOKEN— connectionHINDSIGHT_BANK_ID,HINDSIGHT_DYNAMIC_BANK_ID,HINDSIGHT_AGENT_NAME— bank addressingHINDSIGHT_AUTO_RECALL,HINDSIGHT_AUTO_RETAIN,HINDSIGHT_RETAIN_MODE— lifecycleHINDSIGHT_RECALL_BUDGET,HINDSIGHT_RECALL_MAX_TOKENS— recall sizingHINDSIGHT_BANK_MISSION,HINDSIGHT_DEBUG
Switching backends mid-session is honoured on the next system-prompt rebuild and the next /memory slash command. Existing users with memories.enabled = true|false are migrated to memory.backend = "local"|"off" exactly once on first launch.
