+# Source Intelligence Parsing (Changelog + Patch Header)
+
+## Module
+Concelier
+
+## Status
+IMPLEMENTED
+
+## Description
+Source intelligence parsing for Tier 2 and Tier 3 evidence collection. Includes changelog parsing (debian/changelog, RPM changelog), patch header parsing, and integration with upstream advisory sources (Debian Security Tracker, Red Hat Errata).
+
+## Implementation Details
+- **Modules**: `src/Concelier/__Libraries/StellaOps.Concelier.BackportProof/`, `src/Concelier/__Libraries/StellaOps.Concelier.Connector.Distro.*/`
+- **Key Classes**:
+  - `BackportEvidenceResolver` (`src/Concelier/__Libraries/StellaOps.Concelier.Merge/Backport/BackportEvidenceResolver.cs`) - resolves backport evidence from changelog and patch header sources
+  - `BackportStatusService` (`src/Concelier/__Libraries/StellaOps.Concelier.BackportProof/Services/BackportStatusService.cs`) - backport status determination from parsed source intelligence
+  - `DebianConnector` (`src/Concelier/__Libraries/StellaOps.Concelier.Connector.Distro.Debian/DebianConnector.cs`) - ingests Debian Security Tracker data
+  - `RedHatConnector` (`src/Concelier/__Libraries/StellaOps.Concelier.Connector.Distro.RedHat/RedHatConnector.cs`) - ingests Red Hat Errata data

+## E2E Test Plan
+- [ ] Parse a debian/changelog file and verify CVE fix entries are correctly extracted as Tier 2 evidence
+- [ ] Parse an RPM changelog and verify patch entries are extracted
+- [ ] Parse patch headers and verify commit references and CVE links are extracted as Tier 3 evidence
+- [ ] Verify integration: Debian Security Tracker data feeds into `BackportEvidenceResolver` for backport verdict
+- [ ] Verify Red Hat Errata integration: errata data provides evidence for backport status determination
