EPICON — C-356 Unified Substrate PR: Cycle Sync Recovery + Writer Health Watchdog¶
ID: EPICON-C356-SUBSTRATE-001 Cycle: C-356 (2026-06-28) Actor: Claude Code, operating under operator identity (kaizencycle) Consequence class: Infrastructure recovery + monitoring — additive workflows, state file correction Status: proposed (PR #330)
Intent¶
Advance STATE/CYCLE.txt from C-348 to C-356 (lagging while cycle.json was already correct). Add upstream writer-health canary detection missing from the C-348 unified PR (#325). Patch mobius-bot-state-sync to stamp a health canary file on every run. Add writer-health-watchdog.yml to detect writer failure before drift accumulates.
Root cause of issue #327: mobius-bot-state-sync writer scheduling lapsed. The detector (canon-drift-tripwire) ran correctly 18 times but no upstream alert existed for the writer itself — only for its output. This PR closes that gap.
Scope¶
Changed files: - STATE/CYCLE.txt — advanced C-348 → C-356 - journals/cycles/C-356.json — stub created (bot overwrites on first run) - state/writer-health.json — seeded for watchdog bootstrap - .github/workflows/mobius-bot-state-sync.yml — added writer-health canary write step - .github/workflows/writer-health-watchdog.yml — new Layer 1 detector workflow - catalog/mobius_catalog.json — regenerated
Not touched: cycle.json (already C-356), ledger, vault, journal content, attestation records, constitutional docs, Tier-3 protected paths.
Two-Layer Detection After This Ships¶
| Layer | Workflow | Fires when | Threshold |
|---|---|---|---|
| 1 (NEW) | writer-health-watchdog | Writer silent 14+ days | Before drift |
| 2 (existing) | canon-drift-tripwire | cycle.json drifts 2+ cycles | After drift |
