Backend:
- GET /api/sync/health returns {last_sync_at, last_sync_status,
last_halt_reason, recent_phase_failures, escalation_phase, is_healthy}.
healthy when last run was completed (or none yet), no phase has
tripped the 3-in-a-row escalation, and recent failures <= 1.
- Dashboard + run-level endpoints include `malformed` count so the
Defecte pill can render.
Frontend:
- Health pill in .sync-card-controls with three states — healthy
(success green, check icon), warning (amber, triangle), escalated
(error red, x-octagon + glow). Tooltip exposes the halt reason and
the top phases with recent failures.
- Status-dot + badge add MALFORMED treatment via --compare orange,
distinct from ERROR red. DESIGN.md notes the diagnostic rationale
(ERROR = runtime, MALFORMED = payload source issue).
- Defecte filter pill on dashboard + logs pages. Mobile segmented
control includes Defecte count. Counts wired to the malformed key.
- startSync() shows a native confirm modal when state is
halted_escalation — operator override still possible, not silenced.
- ORDER_STATUS.MALFORMED mirror added to shared.js.
- Cache-bust: style.css v46, shared.js v47, dashboard.js v52,
logs.js v16.
5 endpoint tests cover empty state, completed, failed, escalated,
single-failure warning. Full CI: 257 unit + 33 e2e green.
