Why

Pull requests keep adding their approval notes to the end of one shared history file, so the first to merge pushes the others out of the merge queue. Three did this today. The file already says it is frozen and that notes belong in the pull request, but nothing checked that.

What

A pull request that changes the frozen file now fails its tests, with a message saying where the note belongs. Pull requests already in the queue are unaffected, because the one entry still waiting to land is accepted.

Fixes #5703

The history file says new approvals go in the pull request, but nothing
checked it and 20 commits appended at its end anyway. Each append conflicts
with every other, which dropped queued PRs out of the merge queue.

Fixes #5703

Walkthrough

The change adds a test that reads approved-surface-history.md and checks its SHA-256 digest against two accepted values. The test fails if the file cannot be read or its digest is not listed.

Severity of issue fixed: Medium

Merge Risk: Minimal · up to 1532b

This adds a test that keeps the frozen approval-history file unchanged, matching the file's documented rule. No concrete merge-blocking risk was found. The linked issue's merge-union approach is not implemented, but the repository's established contract does not require it.

Explanation

The only change is scripts/validate-eks-ci-role-policy/history_frozen_test.go. The test directly addresses the shared approval-history conflict described in [#5703] and supports the PR's stated freeze policy. No unrelated change is shown.

Full details: Docstring Coverage

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 1 files.

Full details: Linked Issues check

Explanation

Direct issue [#5703] requires independent approval-history entries to merge without loss, while changes to the same fingerprint line still conflict, with automated validation after the merge. The PR adds only history_frozen_test.go. That test rejects every history-file content except two fixed SHA-256 digests and instructs authors to restore the file. It does not implement or test merge preservation, same-fingerprint conflicts, or the required post-merge validation. No evidence shows the required behavior on real pull requests.

Resolution

Implement an issue-aligned solution. Add the merge or storage behavior that preserves independent entries. Add tests that retain both entries, preserve conflicts for the same fingerprint, and pass go test ./scripts/validate-eks-ci-role-policy after the merge. If the freeze approach is intended instead, update issue [#5703] and its acceptance criteria before relying on it as the fix.
