## Role
Implement the Cisco security advisory connector to ingest Cisco PSIRT bulletins for Feedser.

## Scope
- Identify Cisco advisory feeds/APIs (XML, HTML, JSON) and define incremental fetch strategy.
- Implement fetch/cursor pipeline with retry/backoff and document dedupe.
- Parse advisories to extract summary, affected products, Cisco bug IDs, CVEs, mitigation guidance.
- Map advisories into canonical `Advisory` records with aliases, references, affected packages, and range primitives (e.g., SemVer/IOS version metadata).
- Provide deterministic fixtures and regression tests.

## Participants
- `Source.Common`, `Storage.Mongo`, `Feedser.Models`, `Feedser.Testing`.

## Interfaces & Contracts
- Job kinds: `cisco:fetch`, `cisco:parse`, `cisco:map`.
- Persist upstream metadata (e.g., `Last-Modified`, `advisoryId`).
- Alias set should include Cisco advisory IDs, bug IDs, and CVEs.

## In/Out of scope
In scope: Cisco PSIRT advisories, range primitive coverage.
Out of scope: Non-security Cisco release notes.

## Observability & Security Expectations
- Log fetch/mapping statistics, respect Cisco API rate limits, sanitise HTML. 
- Handle authentication tokens if API requires them.

## Tests
- Add `StellaOps.Feedser.Source.Vndr.Cisco.Tests` with canned fixtures for fetch/parse/map. 
- Snapshot canonical advisories and support fixture regeneration.
