# Advisory AI Guardrails & Evidence Intake
|
|
|
|
_Updated: 2025-12-09 | Owner: Advisory AI Docs Guild | Status: Ready to publish (Sprint 0111 / AIAI-DOCS-31-001)_
|
|
|
|
This note captures the guardrail behaviors and evidence intake boundaries required by Sprint 0111 tasks (`AIAI-DOCS-31-001`, `AIAI-RAG-31-003`). It binds Advisory AI guardrails to upstream evidence sources and clarifies how Link-Not-Merge (LNM) documents flow into Retrieval-Augmented Generation (RAG) payloads.
|
|
|
|
## 1) Evidence sources and contracts
|
|
|
|
**Upstream readiness gates (now satisfied)**
|
|
|
|
- CLI guardrail artefacts (2025-11-19) are sealed at `out/console/guardrails/cli-vuln-29-001/` and `out/console/guardrails/cli-vex-30-001/`; hashes live in `docs/modules/cli/artefacts/guardrails-artefacts-2025-11-19.md`.
|
|
- Policy pin: set `policyVersion=2025.11.19` per `docs/policy/assistant-parameters.md` before enabling non-default profiles.
|
|
- SBOM context service is live: the 2025-12-08 smoke against `/sbom/context` produced `sha256:0c705259fdf984bf300baba0abf484fc3bbae977cf8a0a2d1877481f552d600d` with evidence in `evidence-locker/sbom-context/2025-12-08-response.json` and offline mirror `offline-kit/advisory-ai/fixtures/sbom-context/2025-12-08/`.
|
|
- DEVOPS-AIAI-31-001 landed: deterministic CI harness at `ops/devops/advisoryai-ci-runner/run-advisoryai-ci.sh` emits binlog/TRX/hashes for Advisory AI.
|
|
|
|
**Evidence feeds**
|
|
|
|
- Advisory observations (LNM) - consume immutable `advisory_observations` and `advisory_linksets` produced per `docs/modules/concelier/link-not-merge-schema.md` (frozen v1, 2025-11-17).
|
|
- VEX statements - Excititor + VEX Lens linksets with trust weights; treated as structured chunks with `source_id` and `confidence`.
|
|
- SBOM context - `SBOM-AIAI-31-001` contract: timelines and dependency paths retrieved via `ISbomContextRetriever` (`AddSbomContextHttpClient`), default clamps 500 timeline entries / 200 paths.
|
|
- Policy explain traces - Policy Engine digests referenced by `policyVersion`; cache keys include policy hash to keep outputs replayable.
|
|
- Runtime posture (optional) - Zastava signals (`exposure`, `admissionStatus`) when provided by Link-Not-Merge-enabled tenants; optional chunks tagged `runtime`.
|
|
|
|
All evidence items must carry `content_hash` + `source_id`; Advisory AI never mutates or merges upstream facts (Aggregation-Only Contract).
|
|
|
|
## 2) Guardrail stages
|
|
|
|
1. **Pre-flight sanitization**
|
|
- Redact secrets (AWS-style keys, PEM blobs, generic tokens).
|
|
- Strip prompt-injection phrases; enforce max input payload 16kB (configurable, default).
|
|
- Reject requests missing `advisoryKey` or linkset-backed evidence (LNM guard).
|
|
2. **Prompt assembly**
|
|
- Deterministic section order: advisory excerpts -> VEX statements -> SBOM deltas -> policy traces -> runtime hints.
|
|
- Vector previews capped at 600 chars + ellipsis; section budgets fixed per profile (`default`, `fips-local`, `gost-local`, `cloud-openai`) in `profiles.catalog.json` and hashed into DSSE provenance.
|
|
3. **LLM invocation (local/remote)**
|
|
- Profiles selected via `profile` field; remote profiles require Authority tenant consent plus `advisory-ai:operate` and `aoc:verify`.
|
|
4. **Validation & citation enforcement**
|
|
- Every emitted fact must map to an input chunk (`source_id` + `content_hash`); citations serialized as `[n]` in Markdown.
|
|
- Block outputs lacking citations, exceeding section budgets, or including unredacted PII.
|
|
5. **Output sealing**
|
|
- Store `outputHash`, `inputDigest`, `provenanceHash`; wrap in DSSE when configured.
|
|
- Cache TTL defaults to 24h; regenerate only when inputs change or `forceRefresh=true`.
|
|
|
|
Metrics: `advisory_ai_guardrail_blocks_total`, `advisory_ai_outputs_stored_total`, `advisory_ai_citation_coverage_ratio`. Logs carry `output_hash`, `profile`, and block reason; no secrets or raw prompt bodies are logged.
|
|
|
|
## 3) RAG payload mapping to LNM (summary)
|
|
|
|
| LNM field | RAG chunk field | Notes |
|
|
| --- | --- | --- |
|
|
| `observation._id` | `source_id` | Used for citations and conflict surfacing. |
|
|
| `observation.advisoryId` | `advisory_key` | Keyed alongside task type in cache. |
|
|
| `observation.affected[].purl` | `purl` | Included for remediation + SBOM joins. |
|
|
| `observation.severities[]` | `severity` | Passed through unmerged; multiple severities allowed. |
|
|
| `linkset.conflicts[]` | `conflicts` | Rendered verbatim for conflict tasks; no inference merges. |
|
|
| `provenance.sourceArtifactSha` | `content_hash` | Drives determinism and replay. |
|
|
|
|
See `docs/advisory-ai/evidence-payloads.md` for full JSON examples and alignment rules.
|
|
|
|
## 4) Compliance with upstream artefacts and verification
|
|
|
|
- References: `CONSOLE-VULN-29-001`, `CONSOLE-VEX-30-001`, `CLI-VULN-29-001`, `CLI-VEX-30-001`, `EXCITITOR-CONSOLE-23-001`, `DEVOPS-AIAI-31-001`, `SBOM-AIAI-31-001`.
|
|
- CLI fixtures: expected hashes `421af53f9eeba6903098d292fbd56f98be62ea6130b5161859889bf11d699d18` (sample SBOM context) and `e5aecfba5cee8d412408fb449f12fa4d5bf0a7cb7e5b316b99da3b9019897186` / `2b11b1e2043c2ec1b0cb832c29577ad1c5cbc3fbd0b379b0ca0dee46c1bc32f6` (sample vuln/vex outputs). Verify with `sha256sum --check docs/modules/cli/artefacts/guardrails-artefacts-2025-11-19.md`.
|
|
- SBOM context: fixture hash `sha256:421af53f9eeba6903098d292fbd56f98be62ea6130b5161859889bf11d699d18`; live SbomService smoke (2025-12-08) hash `sha256:0c705259fdf984bf300baba0abf484fc3bbae977cf8a0a2d1877481f552d600d` stored in `evidence-locker/sbom-context/2025-12-08-response.json` and mirrored under `offline-kit/advisory-ai/fixtures/sbom-context/2025-12-08/`.
|
|
- CI harness: `ops/devops/advisoryai-ci-runner/run-advisoryai-ci.sh` emits `ops/devops/artifacts/advisoryai-ci/<UTC>/build.binlog`, `tests/advisoryai.trx`, and `summary.json` with SHA256s; include the latest run when shipping Offline Kits.
|
|
- Policy compatibility: guardrails must remain compatible with `docs/policy/assistant-parameters.md`; configuration knobs documented there are authoritative for env vars and defaults.
|
|
- Packaging tasks (AIAI-PACKAGING-31-002) must include this guardrail summary in DSSE metadata to keep Offline Kit parity.
|
|
|
|
## 5) Operator checklist
|
|
|
|
- LNM feed enabled and Concelier schemas at v1 (2025-11-17).
|
|
- SBOM retriever configured or `NullSbomContextClient` left as safe default; verify latest context hash (`sha256:0c705259f...d600d`) or fixture hash (`sha256:421af53f9...9d18`) before enabling remediation tasks.
|
|
- Policy hash pinned via `policyVersion` when reproducibility is required.
|
|
- CLI guardrail artefact hashes verified against `docs/modules/cli/artefacts/guardrails-artefacts-2025-11-19.md` and mirrored into Offline Kits.
|
|
- CI harness run captured from `ops/devops/advisoryai-ci-runner/run-advisoryai-ci.sh`; store `summary.json` alongside doc promotion.
|
|
- Remote profiles only after Authority consent and profile allowlist are set.
|
|
- Cache directories shared between web + worker hosts for DSSE sealing.
