+# Wake Doctrine
+
+This is the canonical fleet wake/heartbeat doctrine, extracted verbatim from the ratified
+converged wake/heartbeat design (`docs/scratchpads/heartbeat-planning/CONVERGED-DESIGN.md`). It
+governs when agents wake and how a wake is delivered, consumed, and retired.
+
+**Wake only on a real, un-consumed, lane-relevant obligation.** Fixed-interval heartbeats are
+forbidden as the primary wake mechanism; they survive only as a **per-class fallback cadence**
+bounded by urgency SLO, never as the steady state.
+
+**A digest is cumulative state since the last CONSUMED ack**, not an event delta. It is
+self-orienting (who / lane / board-head) and decides the no-op case with **zero tool calls**.
+Actionable facts are **claims-to-verify** carrying a **hard locator** (repo/issue#/SHA/file);
+self-sufficiency never exempts a consequential action from its live gate.
+
+**Consumption is a consumer act, not a delivery act.** Split RECEIVED (delivery; `wake_id`-deduped)
+from CONSUMED (durable capture of a contiguous prefix). Never ack-then-crash-before-capture. Acks
+are local-write-only and cumulative; a turn never blocks on the network to ack.
+
+**Durability is unconditional; coalescing is optional.** Every delivered class is durably stored
+and acked; only machine `digest` wakes coalesce. A parked or absent pane must never lose a human
+or peer message.
+
+**Park is two-phase:** flush-and-checkpoint (recording the CONSUMED cursor) *before* `/clear`.
+
+**Liveness is independent of work-triggering:** an off-host dead-man beacon, alarming on absence —
+never a same-host sibling, never a pane scrape.
+
+**Retire the old net LAST:** run new alongside old, compare ledgers, and cut over only when the
+per-host safety vector (no-op-rate ↓ AND canary-FN=0 AND source-parity-inventory-complete AND
+reconcile=0 AND p95 event→CONSUMED≤SLO AND p95 event→qualified-action≤SLO) passes.
