+# Reincarnation after reboot: target
+
+Status: target, Self, 2026-10-18 (campaign `idunn-reincarnation` in Eureka's
+mind). It states the ends. The body facts, model page and cut sequence will
+live in `reincarnation-map.md`.
+
+## Why
+
+Yggdrasil rebooted at 11:46 UTC on 2026-10-18. Admitted bodies run as
+transient systemd units under `/run/systemd/transient`, and the reboot wiped
+them all. nginx failed at boot, because it bound `10.77.0.1:17871` before
+`wg-gamecult` carried that address. Every stable route, Idunn's own
+`127.0.0.1:8831-8833` included, stayed down until a manual
+`systemctl restart nginx` at about 19:46.
+
+What Idunn did:
+
+- From 11:50 onward continuity spent streampixels-service's whole restart
+  budget (6 per hour) and logged "The target is free for a deployment to
+  replace it: systemd unit … is absent". The log repeated in hourly bursts as
+  the window slid.
+- When nginx returned, ghostlight and streampixels-web were re-incarnated, and
+  streampixels-service was not.
+- An operator-approved `idunn up streampixels-service` (tx-e69f5402) sat in
+  Sealing for about 15 minutes. It then failed with "admitted incumbent failed
+  before candidate fencing; deployment yielded to continuity". Continuity had
+  freed the target for a deployment. The deployment handed it back to
+  continuity. Neither actuated.
+- At 20:46:43 continuity re-incarnated the service under generation
+  tx-0804185a, once the window had slid to 4/6. So the outage was not ended by
+  the deployment the operator approved. The restart window bounded it, a full
+  hour after its cause had cleared.
+- Throughout, several times a second: "preserved admitted … after rejecting
+  topology observation: topology correlation does not bind the current
+  activation", and "rejected admitted streampixels-service route continuity:
+  admitted process write lease is no longer exact".
+
+## Invariants
+
+1. **A reboot is not a fault of the body.** If an admitted body's unit is
+   absent because the host lost its transient units, continuity
+   re-materializes it from the installed body. It needs no deployment, no
+   operator, and no part of the restart budget for that absence.
+2. **The restart budget measures the body.** A failure caused by a shared host
+   dependency, such as nginx, the stable route's listener or Odin, never
+   charges a target's restart budget. A dependency outage can never exhaust
+   the budget of every target behind it.
+3. **Exactly one authority owns a target's actuation at every instant, and
+   the handover is explicit.** When continuity stops, it records that it has
+   stopped, and from then on deployment owns the target. A deployment never
+   yields to a continuity owner that has stopped. A deployment whose incumbent
+   is absent replaces it, with nothing to fence. There is no reachable state
+   in which continuity waits for a deployment while that deployment waits for
+   continuity. A negative test proves it.
+4. **Continuity is daemon survival; deployment is change** (`F:\Projects\CLAUDE.md`).
+   Restarting the admitted installed body never needs a deployment and is
+   never gated by a deployment brake. A deployment brake gates only artifact,
+   revision, configuration, schema, unit or authority changes.
+5. **Rejections of stale observations are not a log stream.** An observation
+   that cannot bind the current activation is either resolved by the owner
+   that can refresh it, or reported once as an incident. It is never
+   re-rejected several times a second.
+6. **Existing invariants hold.** `route-continuity-target.md` 1 to 7 (in
+   particular no actuation from observation, bounded backoff, every
+   post-fencing phase ends) and `authority-map.md` (Idunn's own recovery
+   depends on no managed target).
+
+## Scope
+
+In:
+
+- Idunn's continuity of admitted bodies across a reboot: absent units, the
+  restart budget and what charges it.
+- The handover between continuity and deployment, in both directions.
+- Classifying the topology-correlation and write-lease rejections: the same
+  fault, or a separate one with its own cut.
+- Re-admitting streampixels-service on Yggdrasil. It is running again under
+  tx-0804185a, and the closing proof checks that it survives the fix's
+  install.
+
+Out, and not consumers of this change:
+
+- **nginx's boot order on Yggdrasil.** It is host configuration, owned by
+  `gamecult-ops`. It gets its own operator-approved change and record, not an
+  Idunn cut.
+- **Ghostlight's degraded route** (53 consecutive failures, incident open) is
+  in scope only if the map shows the same fault. Otherwise it is a follow-up.
+- **Heimdall's onboarding failures and its environment.**
+- **Retention of the ~130 dead transient units** on Yggdrasil. It is an ops
+  follow-up already recorded under route continuity.
+- **Luna's 2026-09-27 weekend patches** are not foundation to build on. Where
+  this map meets them, it cuts them.
