Close the three gaps the scoring report itself flagged for H6 plus V15,
each as a real MVP + fail-able adversarial test (same pattern that lifted H5):
- D1 alert-dispatch.sh: alerts POST to a real HTTP webhook (severity routing,
dedup window, retry) + dead-letter queue with redelivery; fail-loud in strict.
Wired into agent-metrics.sh so a failing step pages live end-to-end.
- D2 provider-usage-fetch.sh + telemetry-reconcile.sh: pull usage from a provider
usage HTTP API (all-or-nothing schema gate, fail-loud) + reconcile local vs
provider ground truth — token under-reporting/hidden runs => TELEMETRY_DISCREPANCY.
- D3 dashboard-serve.sh + dashboard-server.py: serve the dashboard over HTTP with
a stale-aware /healthz probe (fresh=200 ok, telemetry silent-death=503 stale).
- D4 circuit-breaker-check.sh: sliding-window failure-rate breaker (V15) — interleaved
successes no longer evade the consecutive-failure breaker (CIRCUIT_OPEN_WINDOW).
New suite phase-h6-agentops-tests.sh: 20/20, all live against local HTTP endpoints
(webhook sink, mock provider API, dashboard server) — deterministic, no model needed.
Also fix sign-policy-bundle.sh key-sync invariant: the local-fallback branch only
exported policy-public.pem when generating a NEW key, so a Vault-DOWN run after a
Vault-signed run verified a local-key signature against the Vault pubkey (RSA padding
error, run-casan4 died mid-suite). Now always re-exports the pubkey before signing —
same fix class as tool-audit-lib.sh / governance-check.sh.
Full battery re-run sequentially: 175/175 PASS, 0 FAIL across 8 suites
(KMS SKIP this run — Vault down; validated live 2026-07-04). Docs synced:
scoring-run-report (H6 79→80, no harness below 80, 155→175), CASAN_HARDENING_STATUS
(Phase 5 D1–D4), Plan-07, submission README, and run-hardening.sh (H6+ scenes HO1–HO4).
