- Defer MCP server discovery off the first-paint critical path for UI sessions; tools and slash commands stream in through the existing live-refresh channel once each server connects (non-UI modes keep the blocking path). ~290ms off first paint with MCP servers configured. - Build the model catalog's canonical-equivalence index lazily on first read instead of eagerly in the ModelRegistry constructor. A default interactive launch never reads it pre-paint, moving the ~210ms build (over ~3,200 models) off the critical path: ~244ms (~16%) off cold boot. - Memoize per-session read summaries (tree-sitter parse) on the content hash of the freshly-read bytes; the file is still read fresh each call so results stay correct. Repeat same-file summary read 17ms -> 2.4ms. - Reuse the Markdown subtree across streaming reveal ticks, memoize grapheme counting, and stop re-highlighting finalized thinking blocks. - Attribute the previously-unlabeled synchronous boot region in the PI_TIMING table and add a bench:guard boot-regression target.

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.
