+# AGENTS
+## Role
+VMware/Broadcom PSIRT connector ingesting VMSA advisories; authoritative for VMware products; maps affected versions/builds and emits psirt_flags.
+## Scope
+- Discover/fetch VMSA index and detail pages via Broadcom portal; window by advisory ID/date; follow updates/revisions.
+- Validate HTML or JSON; extract CVEs, affected product versions/builds, workarounds, fixed versions; normalize product naming.
+- Persist raw docs with sha256; manage source_state; idempotent mapping.
+## Participants
+- Source.Common (HTTP, cookies/session handling if needed, validators).
+- Storage.Mongo (document, dto, advisory, alias, affected, reference, psirt_flags, source_state).
+- Models (canonical).
+- Core/WebService (jobs: source:vmware:fetch|parse|map).
+- Merge engine (later) to prefer PSIRT ranges for VMware products.
+## Interfaces & contracts
+- Aliases: VMSA-YYYY-NNNN plus CVEs.
+- Affected entries include Vendor=VMware, Product plus component; Versions carry fixed/fixedBy; tags may include build numbers or ESXi/VC levels.
+- References: advisory URL, KBs, workaround pages; typed; deduped.
+- Provenance: method=parser; value=VMSA id.
+## In/Out of scope
+In: PSIRT precedence mapping, affected/fixedBy extraction, advisory references.
+Out: customer portal authentication flows beyond public advisories; downloading patches.
+## Observability & security expectations
+- Metrics: SourceDiagnostics emits shared `feedser.source.http.*` counters/histograms tagged `feedser.source=vmware`, allowing dashboards to measure fetch volume, parse failures, and map affected counts without bespoke metric names.
+- Logs: vmsa ids, product counts, extraction timings; handle portal rate limits politely.
+## Tests
+- Author and review coverage in `../StellaOps.Feedser.Source.Vndr.Vmware.Tests`.
+- Shared fixtures (e.g., `MongoIntegrationFixture`, `ConnectorTestHarness`) live in `../StellaOps.Feedser.Testing`.
+- Keep fixtures deterministic; match new cases to real-world advisories or regression scenarios.
