The Pipelines as Code CI is failing on main after the recent dependency update (google.golang.org/grpc from 1.78.0 to 1.79.3). The failure occurs in the unit test task, specifically within webhook validation tests.

Failure details
PipelineRun: push-generate-coverage-releaseyaml-647q9
Namespace: pipelines-as-code-ci

FAIL github.com/openshift-pipelines/pipelines-as-code/pkg/webhook 1.151s
make: *** [Makefile:70: test-unit] Error 1

Error location

validation_test.go:195
assertion failed: true (res.Allowed bool) != false (tt.allowed bool)

Observed behavior
A test expectation in validation_test.go no longer matches the actual result. The test expects Allowed=false, but the code returns Allowed=true.

Expected behavior
Unit tests should pass consistently on main. The validation logic should either:

• remain unchanged and tests should reflect correct expectations, or
• tests should be updated if the behavior change is intentional.

Context
This started after:

chore(deps): bump google.golang.org/grpc from 1.78.0 to 1.79.3

Potential causes

• Behavioral change introduced by grpc update
• Side effect in webhook validation logic (possibly admission handling or context propagation)
• Test relying on assumptions affected by dependency behavior

Suggested actions

• Identify what changed in validation logic or grpc interaction
• Confirm whether the new behavior is correct
• Update test expectations if intentional, otherwise fix regression
