 - **NOTIFY-ATTEST-74-001** – Template matrix (verification failure, expiring attestation, key revoke, witness anomaly) drafted; Section 7 added to `docs/notifications/templates.md` plus cross-references in `notifications/overview.md` and `notifications/rules.md` so rule authors and operators use the canonical `tmpl-attest-*` suite; baseline template exports now live under `offline/notifier/templates/attestation/*.template.json`; waiting on Attestor schema freeze (due 2025-11-13) before locking copy and localization tokens.
 - **NOTIFY-OAS-61-001** – OpenAPI document restructure underway; shared error envelope + examples added, but `quietHours` and `incident` sections still need review with API Contracts Guild.
-- **NOTIFY-OBS-51-001/NOTIFY-OBS-55-001** – Remain TODO pending Telemetry SLO webhook schema + incident toggle contract; coordinate with TELEMETRY-OBS-50/55 tasks.
