-- **Date:** 2026-06-07 (radar loop, pass 21)
-- **Pass 21 — honest empty (3rd running).** content's new CvRDT work (crdt/crdt-tree) is
-  content-exclusive collaborative-editing; events recurrence-id + fed-sx outbox internals
-  are domain-deep, not cross-cutting. No new candidate. Active loops are building *inside*
-  their domains now; radar's next real triggers are **(a)** a new subsystem spawning or
-  **(b)** host-persist's durable adapter landing → unblocks the W4 acl/mod→persist/log
-  migration. Cadence lengthened to ~hourly until one fires.

+  active loops (content CvRDT, events recurrence/reschedule, identity grant-mgmt, fed-sx
+  outbox internals) are building *inside* their domains, not cross-cutting infra. Census
+  exhausted (p17); all gates re-tested (W1 p18, W2 p19). No new candidate clears any gate.
+- **Radar is now trigger-driven.** The next substantive pass needs one of: **(a)** a new
+  subsystem worktree spawning (auto-joins scan), or **(b)** host-persist's durable adapter
+  landing → unblocks the W4 acl/mod→persist/log migration, or **(c)** a quiescent
+  subsystem (acl/mod/search/commerce, static ~9–16 passes) resuming. Polling ~hourly until
+  one fires; will tighten cadence then.
 - **Date:** 2026-06-07 (radar loop, pass 20)
 - **Pass 20 — honest empty pass.** 3 new census recurrences since p17 (normalize/index ×2,
   query ×3) — all **name collisions** (same noun, domain-specific op), added to the table.
