+### M7.14 (Now): Approval-Policy Drift Detection and Alarm-to-Runbook Escalation Automation (Lane Ops Bridge)
+
+Deliverables:
+
+- add deterministic approval-policy drift detection report surface.
+- automate escalation synthesis from remediation alarms plus approval drift signals.
+- keep escalation output runbook-link aware for operator execution.
+
+#### M7.14 Progress Note (2026-04-16)
+
+- [Done] expanded `src/server.ts` with policy-drift route:
+  - `GET /api/knowledge/operator/agent-workspace-diagnostics/triage/remediation/policy/drift?limit=...`.
+- [Done] expanded `src/server.ts` with escalation route:
+  - `GET /api/knowledge/operator/agent-workspace-diagnostics/triage/remediation/escalation?window=...&strategy=...&limit=...`.
+- [Done] added deterministic policy drift + escalation synthesis helpers:
+  - `buildAgentWorkspaceDiagnosticsRemediationPolicyDriftReport(...)`,
+  - `buildAgentWorkspaceDiagnosticsRemediationEscalationActions(...)`,
+  - `normalizeAgentWorkspaceDiagnosticsRemediationDriftInspectLimit(...)`.
+- [Done] expanded evidence coverage:
+  - `src/server.migration.test.ts` now validates drift summary counters, drift signal IDs/severity, and escalation action synthesis from both drift and alarms.
+  - `src/knowledge.api.contract.test.ts` now fail-fast checks policy-drift/escalation route contracts.
+  - `src/agent_workspace.verification.contract.test.ts` + `scripts/verify-agent-workspace-runtime.js` now fail fast on drift/escalation helper and route drift.
+- [Done] verification evidence:
+  - `npm test -- src/server.migration.test.ts --runInBand --testNamePattern "triage route summarizes replay risk|triage history and alert-threshold governance|adaptive threshold simulation and remediation guardrails|remediation backtest and approval-gate flow|approval policy hardening and remediation trend-regression alarms|approval-policy drift detection and alarm-to-runbook escalation stay deterministic"`
+  - `npm run test:agent-workspace:contracts`
+  - `npm run verify:agent-workspace:runtime`

 ## Success Criteria
 
 - CI failure mode that previously blocked the three agent-workspace suites is eliminated on mainline.

+## Latest Mainline Increment (2026-04-16 M7.14 Approval-Policy Drift Detection and Alarm-to-Runbook Escalation Lane)

+- Expanded `src/server.ts` with remediation escalation route:
