AGENTS

Role

Implement the CERT/CC (Carnegie Mellon CERT Coordination Center) advisory connector so Concelier can ingest US CERT coordination bulletins.

Scope

• Identify CERT/CC advisory publication format (VU#, blog, RSS, JSON) and define fetch cadence/windowing.
• Implement fetch, parse, and mapping jobs with cursor persistence and dedupe.
• Normalise advisory content (summary, impacted vendors, products, recommended mitigations, CVEs).
• Produce canonical Advisory objects including aliases, references, affected packages, and range primitive metadata.
• Supply fixtures and deterministic regression tests.

Participants

• Source.Common (HTTP/fetch utilities, DTO storage).
• Storage.Mongo (raw/document/DTO/advisory stores and state).
• Concelier.Models (canonical structures).
• Concelier.Testing (integration tests and snapshots).

Interfaces & Contracts

• Job kinds: certcc:fetch, certcc:parse, certcc:map.
• Persist upstream caching metadata (ETag/Last-Modified) when available.
• Aliases should capture CERT/CC VU IDs and referenced CVEs.

In/Out of scope

In scope:

• End-to-end connector with range primitive instrumentation and telemetry.

Out of scope:

• ICS-CERT alerts (handled by dedicated connector) or blog posts unrelated to advisories.

Observability & Security Expectations

• Log fetch and mapping statistics; surface failures with backoff.
• Sanitise HTML sources before persistence.
• Respect upstream throttling via retry/backoff.

Tests

• Add StellaOps.Concelier.Connector.CertCc.Tests to cover fetch/parse/map with canned fixtures.
• Snapshot canonical advisories and support UPDATE flag for regeneration.
• Ensure deterministic ordering and timestamp normalisation.
