# Zastava Runtime Signals Gaps (ZR1–ZR10)
|
||
|
||
**Source:** `docs/product-advisories/31-Nov-2025 FINDINGS.md`
|
||
**Compiled:** 2025-12-02 (UTC)
|
||
**Scope:** Close ZR1–ZR10 for Observer + Webhook (Surface.Env/Secrets/FS) with offline parity and auditability.
|
||
|
||
## Gap remediation summary
|
||
- **ZR1 · Canonical schemas & hashing**
|
||
- Publish signed JSON Schemas for Observer emission and Webhook admission envelopes under `docs/modules/zastava/schemas/`.
|
||
- Enforce JCS canonical JSON; compute `sha256` over canonical form; include test vectors.
|
||
- Validators reject non-canonical payloads; DSSE required on bundles.
|
||
- **ZR2 · Tenant isolation & scope binding**
|
||
- Require `tenant_id` and `project_id` on all Observer/Webhook requests; fail closed on missing/ambiguous values.
|
||
- Add tenancy annotations to DSSE envelopes and enforce tenancy in admission allowlist.
|
||
- Add cross-tenant negative tests.
|
||
- **ZR3 · Determinism & time source**
|
||
- Use monotonic clock + UTC; standardize ordering: `tenant -> namespace -> workload -> digest`.
|
||
- Add multi-run hash CI to ensure stable serialization.
|
||
- **ZR4 · Provenance & signer identity**
|
||
- Require DSSE envelopes with fields: `sensor_id`, `firmware_version`, `policy_hash`, `graph_revision_id`, `signer_key_id`.
|
||
- Reject unsigned/unknown signer; log provenance to CAS.
|
||
- **ZR5 · Admission side-effects & escape hatches**
|
||
- Side-effect allowlist documented; deny non-listed hooks.
|
||
- Bypass/debug require dual approval and DSSE waiver with expiry; log and alert on use.
|
||
- **ZR6 · Offline/air-gap parity**
|
||
- Provide `zastava-kit` bundle (admissions + observations + schemas + DSSE + hashes) with deterministic tar flags (`--mtime @0 --owner 0 --group 0 --numeric-owner | zstd -19 --long=27`).
|
||
- Include `verify.sh` for hash/signature/tenant checks; no network dependencies.
|
||
- **ZR7 · Replay/audit linkage**
|
||
- Embed `ledger_id` and `replay_manifest` refs in events/admissions; store in CAS.
|
||
- Export linkage in offline kit and Evidence Locker.
|
||
- **ZR8 · Thresholds, burn-rate & anomaly policy**
|
||
- Versioned `thresholds.yaml` with DSSE signatures; change log required.
|
||
- Alerts on threshold change; publish budgets (latency, error rate, drop rate).
|
||
- **ZR9 · PII/redaction & log hygiene**
|
||
- Redaction allowlist + size limits; CI + ingest PII/secret scan.
|
||
- Truncate with omission counts; include `redaction_manifest` in DSSE annotations.
|
||
- **ZR10 · Health, kill-switch & fallback**
|
||
- Fault counter + kill-switch with DSSE-signed disable record.
|
||
- Configurable fail-open/closed (default fail-closed for admission); manual re-enable requires DSSE record.
|
||
|
||
## Artefacts created
|
||
- This remediation plan: `docs/modules/zastava/gaps/2025-12-02-zr-gaps.md` (to be cross-linked from sprint 0144 and TASKS).
|
||
- Delivery paths for schemas/thresholds/kit will be added when produced; DSSE signatures required for all artefacts.
|
||
|
||
## Next steps
|
||
1) Generate schemas + test vectors and place under `docs/modules/zastava/schemas/`; sign DSSE.
|
||
2) Draft `thresholds.yaml` with budgets and sign DSSE.
|
||
3) Build `zastava-kit` bundle + `verify.sh`; include Evidence Locker path and SHA256.
|
||
4) Add tenancy/ordering/provenance enforcement to Observer/Webhook validators and tests; mirror changes in sprint and TASKS boards.
