+# AirGap Import & Verify (runbook outline)
+
+Related advisory: `docs/product-advisories/25-Nov-2025 - Air‑gap deployment playbook for StellaOps.md` (AG1–AG12). Implements AIRGAP-VERIFY-510-014.
+
+## Prerequisites
+- `offline-kit/manifest.json` + `manifest.dsse` and `mirror.manifest` present.
+- Trust roots: Rekor/TUF roots, Authority signing roots, AV/YARA public keys.
+- Tools: `cosign` (or Stella verifier), `sha256sum`, `yara`, `python3`.
+
+## Steps
+1) Verify manifest signature
+   - `cosign verify-blob --key trust-roots/manifest.pub --signature manifest.dsse manifest.json`
+   - Sample helper: `scripts/airgap/verify-offline-kit.sh <kit-root>`
+2) Check staleness and policy/graph hashes
+   - Compare `feeds[*].snapshot` dates to allowed window; ensure `policyHash`/`graphHash` match target site config; fail closed on mismatch unless override signed.
+3) Verify chunks and Merkle root
+   - For each chunk listed in manifest, `sha256sum -c`; recompute Merkle root per manifest recipe; compare to `rootHash` field.
+4) AV/YARA validation
+   - Run `yara -r rules/offline-kit.yar kit/`; confirm `avReport.sha256` matches signed report in manifest; block on any detection.
+5) Replay depth selection
+   - Modes: `hash-only` (default), `full-recompute`, `policy-freeze`. Select via `--replay-mode`; enforce exit codes 0=pass, 3=stale, 4=hash-drift, 5=av-fail.
+6) Ingress/egress receipts
+   - Generate DSSE receipt `{hash, operator, time, decision}`; store in Proof Graph; verify incoming receipts before import.
+
+## Outputs
+- Exit code per replay mode outcome.
+- Receipt DSSE stored at `receipts/{tenant}/{timestamp}.dsse`.
+- Optional report `verify-report.json` summarizing checks.
+
+> Expand with concrete scripts once tasks 510-010..014 land.

 ## Decisions & Risks
 - **Decisions**
@@ -45,7 +45,7 @@
 - **Risks & Mitigations**
  - Policy contract delays block API shape → Keep tasks BLOCKED; proceed once contract lands; reuse Concelier/Vuln canonicalization if applicable.
  - Risk feed envelope unknown → Mirror Risk Engine schema as soon as published; stage behind feature flag.
-  - WebService `PolicyEndpointsTests` excluded due to host-binding flake in CI runner → keep coverage via unit/core tests; re-enable once in-memory host binding is stable.
+  - Policy endpoints test harness injects stub signer/attestation services; test is active and passing (no skips remaining).

 ## Next Checkpoints
 - Await Policy/Risk contract publication; unblock POLICY-20-001/002 and RISK-66-001 upon receipt.

 ## Decisions & Risks
 - Need service-by-service adoption of the hardened Docker template; ensure health endpoints exist (tracked by DOCKER-44-003).
 - SBOM/attestation integration (DOCKER-44-002) depends on final image names/digests from 44-001.
 - Cosign key management: default flow supports keyless (requires transparency); for offline/air-gap, ensure registry mirror and signing keys are available to `sbom_attest.sh`.
 - Surface.Env: ZASTAVA_* fall back to SCANNER_* in Helm/Compose; operators can override per component. Keep `docs/modules/scanner/design/surface-env.md` aligned if prefixes/fields change.
 - Surface.Secrets: provisioning playbook published (`ops/devops/secrets/surface-secrets-provisioning.md`); keep Helm/Compose env in sync. Offline kit already bundles encrypted secrets; ensure unpack path matches `*_SURFACE_SECRETS_ROOT`.
+- Tenant chaos drill requires iptables/root access; run only in isolated CI agents or staging clusters. Ensure JWKS cache TTL is monitored so chaos window does not trigger widespread auth failures.

 ## Verification guidance

+Upcoming EB1–EB10 remediation (Sprint 0161; advisory `docs/product-advisories/28-Nov-2025 - Evidence Bundle and Replay Contracts.md`):
+- Publish `bundle.manifest.schema.json` and `checksums.schema.json` with canonical JSON rules and signatures.
+- Document the Merkle hash recipe and DSSE predicate/log policy.
+- Ship an offline verifier script and golden bundles/replay fixtures to prove determinism.
+- Add incident-mode activation/exit records and redaction/tenant isolation guidance for portable bundles.
+
+### Merkle recipe (example)
+```bash
+cd bundle
+find . -type f ! -name checksums.txt -print0 | sort -z | xargs -0 sha256sum > checksums.txt
+sha256sum checksums.txt | awk '{print $1}' > merkle-root.txt
+```
+Use the resulting root as the DSSE subject and store `checksums.txt` inside the bundle.
+
 1. Download `bundle.tgz` and read `instructions.txt`; the first section lists bundle id, root hash, and creation/timestamp information.
 2. Verify `checksums.txt` against the transferred archive to detect transit corruption.
 3. Use the StellaOps CLI (`stella evidence verify bundle.tgz`) or the provenance verifier library to validate `signature.json`.

+## Gap remediation (EC1–EC10)
+- Schemas: publish signed `ExportProfile` + manifest schemas with selector validation; keep in repo alongside OpenAPI docs.
+- Determinism: per-adapter ordering/compression rules with rerun-hash CI; pin Trivy DB schema versions.
+- Provenance: DSSE/SLSA attestations with log metadata for every export run; include tenant IDs in predicates.
+- Integrity: require checksum/signature headers and OCI annotations; mirror delta/tombstone rules documented for adapters.
+- Security: cross-tenant exports denied by default; enforce approval tokens and encryption recipient validation.
+- Offline parity: provide export-kit packaging + verify script for air-gap consumers; include fixtures under `src/ExportCenter/__fixtures`.
+- Advisory link: see `docs/product-advisories/28-Nov-2025 - Export Center and Reporting Strategy.md` (EC1–EC10) for original requirements and keep it alongside sprint tasks for implementers.
+
 ## Job lifecycle
 1. **Profile selection.** Operator or automation picks a profile (`json:raw`, `json:policy`, `trivy:db`, `trivy:java-db`, `mirror:full`, `mirror:delta`) and submits scope selectors (tenant, time window, products, SBOM subjects, ecosystems). See `docs/modules/export-center/profiles.md` for profile definitions and configuration fields.
 2. **Planner resolution.** API validates selectors, expands include/exclude lists, and writes a pending `export_run` with immutable parameters and deterministic ordering hints.

+# CVSS v4.0 Receipts – Hardening Guide
+
+Source advisory: `docs/product-advisories/25-Nov-2025 - Add CVSS v4.0 Score Receipts for Transparency.md` (CV1–CV10). This guide turns the gaps into implementable rules for Sprint 0190.
+
+## Canonical hashing (CV2)
+- Serializer: JSON Canonicalization Scheme (JCS).
+- Ordering: lexicographic keys; arrays keep order; drop nulls.
+- Numbers: fixed 4-decimal precision; invariant culture; no exponent.
+- Time: UTC ISO-8601 `Z`; strip milliseconds unless non-zero.
+- Hash: SHA-256 of canonical JSON; store as `inputsHash` and DSSE subject.
+- Test vectors: `tests/Policy/StellaOps.Policy.Scoring.Tests/Fixtures/hashing/`.
+
+## Policy replay & backfill (CV1)
+- Policies immutable; bump version for any change.
+- On change, emit new receipts with `supersedesReceiptId` and retain old ones.
+- Backfill job: re-score under new policy, append history, re-sign DSSE.
+
+## Tenant segregation & RBAC (CV4, CV9)
+- Storage keys include `tenantId`; hashes/DSSE annotate tenant.
+- Roles: Security Engineer (Base), SOC Analyst (Threat), Customer Admin (Env), Viewer (read-only).
+- Enforce at API/repo layer and in canonical hash.
+
+## Deterministic exports (CV8)
+- JSON export: JCS ordering, UTF-8, UTC timestamps, stable severity palette.
+- PDF export: embed fonts (Source Sans 3 + Roboto Mono), A4, fixed margins; hash PDF bytes and persist `exportHash`.
+
+## v3.1 → v4.0 conversion (CV5)
+- Deterministic mapping; tag `source: "converted-v3.1"`, set `conversionMethod` + `confidence`; retain vendor vector.
+
+## Evidence provenance (CV6)
+- Evidence items use CAS URIs + DSSE refs, include `retentionClass`, `redactionStatus`, `verifiedAt`, `hashMismatch`.
+
+## Immutability & monitoring (CV7, CV10)
+- Receipts append-only; amendments create new IDs + DSSE.
+- Alerts: DSSE verify failures, policy hash drift, hash mismatch, engine version skew. Prometheus counters: `cvss_receipt_dsse_failures_total`, `cvss_policy_drift_total`, `cvss_hash_mismatch_total`.
+
+## Golden fixtures & locations
+- Hashing vectors: `src/Policy/__Tests/StellaOps.Policy.Scoring.Tests/Fixtures/hashing/example-receipt-input.json` with expected hash `example-receipt-input.sha256`.
+- Receipts/exports under `tests/Policy/StellaOps.Policy.Scoring.Tests/Fixtures/` (expand as features land).
+- Sample PDFs in `Fixtures/exports/` once generated.
+
+## Implementation checklist
+- Wire `ReceiptCanonicalizer` to JCS rules above.
+- Add backfill job + history persistence.
+- Enforce tenant/RBAC and annotate hashes/DSSE.
+- Implement deterministic PDF export and record `exportHash`.
+- Store conversion metadata for v3.1 sources.
+- Verify evidence CAS/DSSE on ingest; fail closed.
+- Expose metrics/alerts listed above.

+# Implementor Guidelines (checklist draft)
+
+Reference: `docs/product-advisories/30-Nov-2025 - Implementor Guidelines for Stella Ops.md` (IG1–IG10) and Sprint 300 task IMPLEMENTOR-GAPS-300-018.
+
+## CI lint & docs linkage (IG7)
+- Require PRs to either touch referenced docs or set `docs: n/a` with justification.
+- Sample hook (to implement): `.git/hooks/pre-commit` invoking `scripts/lint-docs-touch.sh`.
+- Fail CI if sprint/AGENTS references are missing for the module being changed.
+
+## Determinism & offline posture (IG2, IG3)
+- Default to offline/no-network; flag any outbound calls in tests.
+- Set deterministic env vars (`TZ=UTC`, `LC_ALL=C`, `PYTHONHASHSEED=0`, etc.).
+- Enforce pinned tool/DB versions and stable ordering in outputs.
+
+## Secrets & provenance (IG5, IG9)
+- Run secret scan pre-commit/CI; forbid committing `.env`/keys.
+- DSSE/provenance required where predicates exist; verify signatures in CI when fixtures are present.
+
+## Schema/versioning control (IG1)
+- Any schema change requires version bump + changelog entry; add canonical serialization tests.
+- Store schemas alongside fixtures where practical.
+
+## Performance/quota (IG6)
+- Define perf budget per service (P95 latency/CPU/memory) and add smoke tests on reference profile.
+
+## Boundaries & shared libs (IG8)
+- Document allowed shared libraries per module; add codeowners/analyzer rules to block cross-boundary calls.
+
+## Evidence & documentation sync (IG10)
+- AGENTS files and sprint docs must link to this checklist; update both when rules change.
+

+# Tenant audit pipeline & chaos plan (DEVOPS-TEN-49-001)
+
+Scope: deploy audit pipeline, capture tenant usage metrics, run JWKS outage chaos tests, and benchmark tenant load/perf.
+
+## Pipeline components
+- **Audit collector**: scrape structured logs from services emitting `tenant`, `subject`, `action`, `resource`, `result`, `traceId`. Ship via OTLP->collector->Loki/ClickHouse.
+- **Usage metrics**: Prometheus counters/gauges
+  - `tenant_requests_total{tenant,service,route,status}`
+  - `tenant_rate_limit_hits_total{tenant,service}`
+  - `tenant_data_volume_bytes_total{tenant,service}`
+  - `tenant_queue_depth{tenant,service}` (NATS/Redis)
+- **Data retention**: 30d logs; 90d metrics (downsampled after 30d).
+
+## JWKS outage chaos
+- Scenario: Authority/JWKS becomes unreachable for 5m.
+- Steps:
+  1. Run synthetic tenant traffic via k6 (reuse `ops/devops/vuln/k6-vuln-explorer.js` or service-specific scripts) with `X-StellaOps-Tenant` set.
+  2. Block JWKS endpoint (iptables or envoy fault) for 5 minutes.
+  3. Assert: services fall back to cached keys (if within TTL), error rate < 1%, audit pipeline records `auth.degraded` events, alerts fire if cache expired.
+- Metrics/alerts to watch: auth cache hit/miss, token validation failures, request error rate, rate limit hits.
+
+## Load/perf benchmarks
+- Target: 5k concurrent tenant requests across API surfaces (Policy, Vuln, Notify) using k6 scenario that mixes read/write 90/10.
+- SLOs: p95 < 300ms read, < 600ms write; error rate < 0.5%.
+- Multi-tenant spread: at least 10 tenants, randomised per VU; ensure metrics maintain `tenant` label cardinality cap (<= 1000 active tenants).
+
+## Implementation steps
+- Add dashboards (Grafana folder `StellaOps / Tenancy`) with panels for per-tenant latency, error rate, rate-limit hits, JWKS cache hit rate.
+- Alert rules: `tenant_error_rate_gt_0_5pct`, `jwks_cache_miss_spike`, `tenant_rate_limit_exceeded`.
+- CI: add chaos test job stub (uses docker-compose + iptables fault) gated behind manual approval.
+- Docs: update `deploy/README.md` Tenancy section once dashboards/alerts live.
+
+## Artefacts
+- Dashboard JSON: `ops/devops/tenant/dashboards/tenant-audit.json`
+- Alert rules: `ops/devops/tenant/alerts.yaml`
+- Chaos script: `ops/devops/tenant/jwks-chaos.sh`

+# Vuln Explorer analytics pipeline plan (DEVOPS-VULN-29-003)
+
+Goals: instrument analytics ingestion (query hashes, privacy/PII guardrails), update observability docs, and supply deployable configs.
+
+## Instrumentation tasks
+- Expose Prometheus counters/histograms in API:
+  - `vuln_query_hashes_total{tenant,query_hash}` increment on cached/served queries.
+  - `vuln_api_latency_seconds` histogram (already present; ensure labels avoid PII).
+  - `vuln_api_payload_bytes` histogram for request/response sizes.
+- Redact/avoid PII:
+  - Hash query bodies server-side (SHA256 with salt per deployment) before logging/metrics; store only hash+shape, not raw filters.
+  - Truncate any request field names/values in logs to 128 chars and drop known PII fields (email/userId).
+- Telemetry export:
+  - OTLP metrics/logs via existing collector profile; add `service=\"vuln-explorer\"` resource attrs.
+
+## Pipelines/configs
+- Grafana dashboard will read from Prometheus metrics already defined in `ops/devops/vuln/dashboards/vuln-explorer.json`.
+- Alert rules already in `ops/devops/vuln/alerts.yaml`; ensure additional rules for PII drops are not required (logs-only).
+
+## Docs
+- Update deploy docs (`deploy/README.md`) to mention PII-safe logging in Vuln Explorer and query-hash metrics.
+- Add runbook entry under `docs/modules/vuln-explorer/observability.md` (if absent, create) summarizing metrics and how to interpret query hashes.
+
+## CI checks
+- Unit test to assert logging middleware hashes queries and strips PII (to be implemented in API tests).
+- Add static check in pipeline ensuring `vuln_query_hashes_total` and payload histograms are scraped (Prometheus snapshot test).

- Script `ops/devops/vuln/verify_projection.sh` (to be added) should:
-  - Run projector against fixture events and compute hash of materialized view snapshot (`sha256sum` over canonical JSON export).
-  - Compare with expected hash stored in `ops/devops/vuln/expected_projection.sha256`.

+  - Exits non-zero on mismatch; use in CI after projector replay.

 ## Fixtures
 - Store deterministic replay fixture under `samples/vuln/events/replay.ndjson` (generated offline, includes mixed tenants, disputed findings, remediation states).
 - Export canonical projection snapshot to `samples/vuln/events/projection.json` and hash to `ops/devops/vuln/expected_projection.sha256`.

- Alerts: `vuln_projection_lag_gt_60s`, `vuln_projection_error_rate_gt_1pct`, `vuln_api_latency_p95_gt_300ms`, `merkle_anchor_stale_gt_15m`.
