Suggested reviewers: Merge Risk: 🟡 Moderate · up to Policy behavior reports can compare a candidate against stale or changing baseline policy inputs, making release changelog results unreliable. Pin the baseline references before merging; clarify stdout-mode artifact behavior as well. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Use old and new release images.json files for CLI and policy behavior comparisons, and use those immutable references for changelog source comparisons. Ref: https://redhat.atlassian.net/browse/EC-2216 Assisted-by: Codex
Permit the explicit shared comparison timestamp to become past while image pulls and setup complete. Ref: https://redhat.atlassian.net/browse/EC-2216 Assisted-by: Codex

In `@hack/generate-changelog.sh`:
- Line 256: Update find_previous_images_file to restrict baseline candidates to
finalized release directories, excluding the documented custom path
releases/my-candidate before reverse sorting. Preserve selection of the newest
valid timestamped release, and add coverage for both a timestamped release and
releases/my-candidate.

Use the complete Golden policy resource for each EC run, injecting the release-policy reference and target collection. Select the newest available x86_64 Golden RPM calculation tag. Ref: https://redhat.atlassian.net/browse/EC-2216 Assisted-by: Codex
Restrict automatic previous-images selection to timestamped finalized release directories so scratch candidates cannot become the comparison baseline. Ref: https://redhat.atlassian.net/browse/EC-2216 Assisted-by: Codex
Keep the Golden policy template beside the comparison script and target configuration instead of at the repository root. Ref: https://redhat.atlassian.net/browse/EC-2216 Assisted-by: Codex
Restore the existing :konflux-to-:latest changelog and release generation behavior. Use the generated candidate images.json only as input to the policy behavior comparison and append that report to changelog.md. Ref: https://redhat.atlassian.net/browse/EC-2216 Assisted-by: Codex
Accept either one candidate images.json for :konflux-to-candidate generation or old and new images.json files for an exact historical release comparison. Ref: https://redhat.atlassian.net/browse/EC-2216 Assisted-by: Codex

In `@hack/policy-behavior/compare-policy-behavior.sh`:
- Around line 357-358: Update the baseline setup around before_cli_ref and
before_policy_ref to resolve both :konflux references to immutable digests once
before validation, then reuse those digest-qualified references for every
run_validation invocation and rendered policy input. Do not pass the mutable
tags directly to Docker or policy rendering.
In `@README.md`:
- Around line 61-63: Update the README statement about release files remaining
available after an operational error to apply only when a release directory is
supplied, such as when RELEASE_DIR is not “-”. Keep the separate stdout-mode
description and accurately note that its temporary images.json is removed on
exit.
