 - **In-app multi-agent conductor**: `services/flow-runner.ts` runs a flow by inserting each step as a `tasks` row (the existing dispatcher runs it) and advancing on a new `onTaskTerminal` dispatcher-deps hook; persisted in `flow_runs`/`flow_steps` (resumed at startup via `initResume`). The 22 conductor flow defs + Spine factory are re-homed under `src/conductor/`. Pure scheduler/resume helpers in `flow-runner-decisions.ts`. Full design: `openspec/changes/archived/orchestrator/`.
 - **Read-only is load-bearing — don't add a dispatch path that bypasses it.** Every step dispatches `agent='qwen', mode_id='plan'`; `dispatcher.ts` force-routes qwen+plan to the PTY `--approval-mode plan` gate and HARD-FAILS the task (never falls to write-capable native inference) when qwen is unavailable (`shouldFailOnMissingAgent`). `BOOCODE_TOOLS` gates BooChat's NATIVE inference tools only — it does NOT govern an external CLI agent (qwen/opencode bring their own write tools); read-only for a dispatched agent is the agent-layer mode (PTY `--approval-mode plan`; ACP `setSessionMode` is fail-OPEN by default, fail-CLOSED for `plan` via `READ_ONLY_MODE_IDS` in `acp-dispatch.ts`).

+## Edit safety guards (v2.8)

+- **`services/edit-guards.ts`** — `validateEditResult(original, updated, filePath)` runs in `pending_changes.ts` immediately before `writeFileAtomic`. Rejects catastrophic truncation (>60% char loss AND >50% line loss). Throws a `formatGuardError` message that percolates to the agent as a visible error.
+- **`services/edit-guards-imports.ts`** — `checkDroppedImports(original, updated, filePath)` detects removed import/require lines. Called alongside the truncation guard.
+- Both guards run on the `/apply` path only (not on queue). Re-queued identical edits re-validate at apply time.
+- Guard functions are pure — no DB or filesystem access. Easy to unit-test.
