📝 WalkthroughWalkthroughThe UniFi GitRepository now verifies the pinned commit’s HEAD signature with the Merge Risk: 🟠 High · up to The PR adds Git signature verification for the UniFi source, but the authorization validator can still accept additional key material in the Secret and thereby trust unintended signers. Merge should be blocked until the Secret rejects the data field and a regression test covers that case. Thanks for using CodeRabbit! It's free for OSS, and your support helps us grow.

- Around line 412-418: In the test setup around validateUnifiSigningKey, safely
type-assert tampered[0]["stringData"] to map[string]any and call t.Fatal when
the assertion fails before modifying github.asc; retain the existing
tampered-key validation for valid stringData maps.
In `@scripts/validate-eks-ci-role-policy/main.go`:
- Around line 1400-1409: Update the unifi Git signing key Secret validation
around stringData to reject any present data field, including additional entries
such as data.attacker.asc, before accepting the Secret; add a regression case
covering this payload while preserving the existing github.asc-only validation.

Summary
HEADmodeEvidence
The issue evidence predates the immutable source pin: the live manifest already names exact commit
7b17f7e33ef507c24c395b884a433c62b92ace98, so this keeps that boundary and adds signature verification rather than returning to a moving branch. That commit verifies with active GitHub key fingerprint968479A1AFF927E37D1A566BB5690EEEBB952194; an unsigned empty-commit control is rejected.Across all five production projections, the render moves from 539 to 540 documents: one public-key Secret is added and only the existing
unifi/unifiGitRepository changes. Role 11, ClusterRole 24, RoleBinding 15, ClusterRoleBinding 12, and ServiceAccount 16 remain unchanged.Validation
