Concelier ingests signed advisories from 32 advisory connectors and converts them into immutable observations plus linksets under the Aggregation-Only Contract (AOC).

Advisory Sources (32 connectors):

National CERTs (8): ACSC (Australia), CCCS (Canada), CERT-Bund (Germany), CERT-CC (US), CERT-FR (France), CERT-IN (India), JVN (Japan), KISA (Korea)
OS Distros (5): Alpine SecDB, Debian Security Tracker, RedHat OVAL, SUSE OVAL, Ubuntu USN
Vendors (7): Apple, Adobe, Chromium, Cisco PSIRT, Microsoft MSRC, Oracle, VMware
Standards (5): CVE, NVD, GHSA (GitHub), OSV, EPSS v4
Threat Intel (3): KEV (CISA Exploited Vulns), CISA ICS, Kaspersky ICS
Regional (3): Russia BDU, Russia NKCKI, Plus regional mirrors
Internal (1): StellaOps internal mirror

Responsibilities

Fetch and normalise vulnerability advisories via restart-time connectors.
Persist observations and correlation linksets without precedence decisions.
Emit deterministic exports (JSON, Trivy DB) for downstream policy evaluation.
Coordinate offline/air-gap updates via Offline Kit bundles.
Serve paragraph-anchored advisory chunks for Advisory AI consumers without breaking the Aggregation-Only Contract.

Key components

StellaOps.Concelier.WebService orchestration host.
Connector libraries under StellaOps.Concelier.Connector.*.
Exporter packages (StellaOps.Concelier.Exporter.*).

Recent updates

2025-11-07: Paragraph-anchored /advisories/{advisoryKey}/chunks endpoint shipped for Advisory AI paragraph retrieval. Details and rollout notes live in ../../implplan/archived/updates/2025-11-07-concelier-advisory-chunks.md.

Integrations & dependencies

PostgreSQL (schema vuln) for canonical observations and schedules.
Policy Engine / Export Center / CLI for evidence consumption.
Notify and UI for advisory deltas.

Operational notes

Connector runbooks in ./operations/connectors/.
Mirror operations for Offline Kit parity.
Grafana dashboards for connector health.
Authority toggle rollout (2025-10-22 update). Follow the phased table and audit checklist in ../../10_CONCELIER_CLI_QUICKSTART.md when enabling authority.enabled/authority.allowAnonymousFallback, and cross-check the refreshed ./operations/authority-audit-runbook.md before enforcement.

Epic alignment

Epic 1 – AOC enforcement: uphold raw observation invariants, provenance requirements, linkset-only enrichment, and AOC verifier guardrails across every connector.
Epic 10 – Export Center: expose deterministic advisory exports and metadata required by JSON/Trivy/mirror bundles.

Implementation Status

Delivery Phases:

Phase 1 (Guardrails & schema) – PostgreSQL validators, AOCWriteGuard interceptor, deterministic linkset builders operational
Phase 2 (API & observability) – Ingestion/verification endpoints with Authority scopes, telemetry, Offline Kit packaging
Phase 3 (Experience polish) – CLI/Console affordances, Export Center hand-off metadata, CI enforcement

Acceptance Criteria:

PostgreSQL validators and runtime guards reject forbidden fields and missing provenance with ERR_AOC_00x codes
Linksets and supersedes chains deterministic; identical payloads yield byte-identical documents
CLI stella aoc verify exits non-zero on violations, zero on clean datasets
Export Center consumes advisory datasets without legacy normalized fields
CI fails on lint violations or guard test regressions

Key Risks & Mitigations:

Collector drift: guard middleware + CI lint + schema validation; RFC required for linkset changes
Migration complexity: staged cutover with backup copies, temporary views for Policy Engine parity
Performance overhead: guard remains O(number of keys), index review for insert latency targets
Tenancy leakage: tenant required in schema, Authority claims enforced, observability alerts

Recent Milestones:

Sprint 110 attestation chain validated, evidence bundle tests green
Link-Not-Merge cache and console consumption docs frozen
Observation events transport reviewed, NATS/air-gap guidance updated
