# RHSA Fixture Diffs for Conflict Resolver (Sprint 1)

_Status date: 2025-10-11_

The Red Hat connector fixtures were re-baselined after the model helper rollout so that the conflict resolver receives the canonical payload shape expected for range reconciliation.

## Key schema deltas

- `affectedPackages[]` now emits the `type` field ahead of the identifier and always carries a `normalizedVersions` array (empty for NEVRA/CPE today) alongside existing `versionRanges`.
- All nested `provenance` objects (package ranges, statuses, advisory-level metadata, references) now serialize in canonical order – `source`, `kind`, `value`, `decisionReason`, `recordedAt`, `fieldMask` – to align with `AdvisoryProvenance` equality used by the conflict resolver.
- `decisionReason` is now present (null) on provenance payloads so future precedence decisions can annotate overrides without another fixture bump.

## Impact on conflict resolver

- Range merge logic must accept an optional `normalizedVersions` array even when it is empty; RPM reconciliation continues to rely on NEVRA primitives (`rangeKind: "nevra"`).
- Provenance comparisons should treat the new property ordering and `decisionReason` field as canonical; older snapshots that lacked these fields are obsolete.
- Advisory/reference provenance now matches the structure that merge emits, so deterministic hashing of resolver inputs will remain stable across connectors.

## Updated goldens

- `src/StellaOps.Concelier.Connector.Distro.RedHat.Tests/RedHat/Fixtures/rhsa-2025-0001.snapshot.json`
- `src/StellaOps.Concelier.Connector.Distro.RedHat.Tests/RedHat/Fixtures/rhsa-2025-0002.snapshot.json`
- `src/StellaOps.Concelier.Connector.Distro.RedHat.Tests/RedHat/Fixtures/rhsa-2025-0003.snapshot.json`

Keep these notes in sync with any future provenance or normalized-rule updates so the conflict resolver team can reason about fixture-driven regressions.
