Memtrace

Memtrace code search & Code Graph

The Memtrace top-row mode, the Code Intelligence sidebar drawer, and the project window’s Code Graph tab. An auto-started Memtrace daemon (localhost:4848 / 4848-mcp) indexes all project paths for live semantic code search; a parent-directory workspace traces sibling repos, with status, version, and update controls in the drawer.

MCP tool: orbit_code_search (plus the Memtrace MCP tools).

Cortex governance and decision lineage

Settings → Memtrace → Governance intake; the Pipeline Code Impact Check. Cortex is Memtrace’s decision-memory layer: managed rule changes are previewed into Cortex before they take effect, decision IDs stay stable over time, and an agent (or you) can ask why a symbol exists, verify a decision’s current detail, and see governing decisions surfaced during approval. None of this blocks approval when Cortex happens to be unavailable — it degrades to no extra context rather than stalling the run.

MCP tools: orbit_recall_decision, orbit_why_here, orbit_decision_detail.

Memtrace Fleet observation log

Memtrace panel → Fleet log; conflict warnings; Needs You. When Memtrace is healthy, Orbit records prompt intents and edit episodes across agents working the same project, and surfaces overlap warnings by severity class — Class B overlaps are shown for awareness, Class C collisions route to Needs You for a human look. Neither class gates launch, integration, or shipping on its own.

File locks

Pipeline advisory chips plus preamble enforcement. Mark files or globs that queued prompts must not touch; agents self-enforce via their preamble, and Orbit rejects a completion (❌ Failed) if the commit modified a locked file — the commit itself is never rolled back. Surfaced in orbit_status as fileLocks.

MCP tools: orbit_lock_file, orbit_list_locks, orbit_unlock_file.
