+Product/infra tooling — shelved during the stability window (no `.dag`-correctness leverage right now). **One slice un-shelved (operator-directed): the roadmap-as-spawner MVP below** — it earns `.dag`-correctness leverage by making the roadmap the single authority for tracked work (§3) and is the first inhabitant of migrating ctrl onto the substrate (§7).
 
 - [ ] idea → PR pipeline *(deferred)*
+- [ ] **roadmap-as-spawner MVP** *(active — operator-directed, un-shelves this slice)* — the gunbc roadmap `.dag` becomes the work-tracking DAG that drives ctrl session spawns. **Structure** (what work exists, deps, sizing, acceptance) lives only in the `.dag` (single authority §3, edited by committing to main); **runtime state** (done/live-session) flows ctrl→gunbc read-only as acceptance evidence — two kinds of fact, one home each, no dual authority. gunbc emits `roadmap-spawn-request/v1` via `roadmap_next_spawnable` (graph readiness = not-done ∧ deps-done); a thin ctrl bridge consumes it, dedups vs live sessions, and reuses the existing auto-spawn poller (zero new spawn code, #1812 merged). **Fail-closed pause kill switch** (§5, default paused — a missing/garbled control file spawns nothing). Stage 2 migrates spawn/session-management onto the `.dag` host-effect `apply()` seam (host-effect-orchestration Phase D/E), shrinking the ctrl realization toward zero (§7).
