mosaic-coderandClaude Opus 4.8 ce53b0e646 feat(wake): W7 (vi) fold in W6 monitor-integration hardening in beacon.sh
ci/woodpecker/pr/ci Pipeline failed
Details 
Separate, clearly-labeled commit for observation set (vi) from the #910 review.
The HMAC-verify half is a non-trivial blast radius (emit must sign, record must
verify-and-bind), so it is isolated here rather than expanding the installer diff.
Both changes are additive and backward-compatible (the legacy unsigned path and
emit_ts fallback are preserved when no key is configured).

(vi-a) Monitor-side ingested_ts: `record` stamps the monitor's own receive-time,
       and `check` computes staleness from ingested_ts (falling back to emit_ts
       only for a legacy record). A host shipping a far-future emit_ts to defer
       its own staleness can no longer fool the off-host dead-man clock.
(vi-b) Beacon HMAC-verify at record: when a key name is configured
       (WAKE_BEACON_HMAC_KEY_NAME / WAKE_HMAC_KEY_NAME), `emit` signs the beacon
       core via the existing sign.sh sign-digest path and `record` verifies via
       sign.sh verify AND binds the envelope to this beacon (content_hash ==
       sha256(core), seq/emit_ts match). A spoofed or unsigned beacon is REJECTED
       fail-loud and never advances the received clock. Key is by-name only —
       beacon.sh inlines no key material.

test-wake-beacon.sh extended with B11 (ingested_ts staleness) and B12 (HMAC-verify
+ spoof/unsigned rejection); test-wake-install.sh gains I7/I8 for the same
invariants. Both harnesses shown red-first under targeted mutation, then green.

Part of #892

mosaic-coderandClaude Opus 4.8 231ba2ef32 feat(wake): W7 A10 idempotent component installer + mosaic-wake.service 
Framework install machinery for the wake component (EPIC #892 W7, the last
build slice). ADDITIVE per #869: adds an `install.sh --component wake` early
dispatch that never enters the full-framework sync, never alters
framework-manifest ownership behavior, and touches nothing the #869
install-ordering-guard covers (no runtime-asset linking, no lease-enforcement
hook wiring).

(i)   Idempotent component-manifest install + Gate A (wake-install.sh install):
      the wake manifest.txt is VERSION METADATA ONLY; the component file set is
      INTERSECTED-AND-VALIDATED against the single SSOT framework-manifest.txt.
      A candidate the SSOT does not own is REFUSED fail-closed with no partial
      write. Re-running writes zero files (no diff).
(ii)  systemd/user/mosaic-wake.service — the long-lived detector daemon
      (detector.sh run). Per-class SLO lives inside the daemon, not a systemd
      interval; it is a SERVICE not a timer, so blank-reset does not apply.
(iii) blank-reset idiom on the legacy mosaic-heartbeat@<agent>.timer cadence
      drop-in during the §5 overlap->retire lifecycle (empty OnUnitActiveSec=
      reset before the new value => exactly one OnUnitActiveUSec), with a
      reset->verify->retire acceptance path (retire LAST, only on §4-vector pass).
(iv)  snapshot-guard — a reap/clean-checkout of a deployed unit is REFUSED
      without a prior snapshot (the deployed-from-uncommitted failure class).
(v)   fail-closed alarm-target + HMAC-key install-validation (G1/G2a): the
      operator W6 alarm sink must be configured + reachable and the W3/W7 HMAC
      key must resolve BY NAME; missing/unreachable => FAIL LOUD. The installer
      ships/writes NO endpoint value and NO secret, and echoes neither.

Red-first harness test-wake-install.sh (6 groups) wired into test:framework-shell;
Gate-A parity extended to prove bash+TS both resolve the wake component paths
framework-owned. wake component manifest bumped 0.5.0 -> 0.6.0.
