Review comments at @test/extended/apiserver/admission_control.go:
- Around line 397-398: Update the proxy setup in the test’s transport
initialization to use http.ProxyFromEnvironment, so both HTTPS_PROXY and
https_proxy are handled consistently; remove the manual environment check and
URL parsing.
- Around line 191-192: Replace the `bash -c` invocation that builds `command`
with a POST sent through `http.Client`, reusing the existing request setup where
possible and preserving the response status handling in
`postSubjectAccessReviewStatus`. Do not place the bearer token or URL in a shell
command.
- Line 135: Update the namespace-deletion polling check to require trimmed
`chkNamespaceOutput` to be empty before succeeding, rather than using
`strings.Contains` with an empty substring. Start the duration measurement
before deletion is initiated and include the wait for empty output so the
90-second regression check covers the full deletion latency.

Review comments at @test/extended/apiserver/audit_logging.go:
- Around line 206-207: In the audit logging test, validate that
strings.TrimSpace(output) is nonempty before splitting it into lines; then keep
the existing line-count assertion for the resulting output. Locate this logic by
the lines variable and its strings.Split call.
- Line 137: Replace the nonempty-length checks on
apiServer.Spec.Audit.CustomRules with assertions that verify the complete
expected rule list after each patch, including each rule’s Group and Profile;
ensure the assertion covering the expected “None” profile checks that value
explicitly.
- Around line 199-201: Update the audit-log loop in the test around the
`node-logs` invocation to inspect each audit-log file’s mode on every master
node and assert the required mode or forbidden permission bits. Keep the
existing log-content availability check separate from the permission assertion.

Review comments at @test/extended/apiserver/quota.go:
- Around line 466-467: Update the ocpObjectCountsYamlFile construction to use
the tmpdir created by the JustBeforeEach hook, keeping the YAML file inside the
per-test directory so JustAfterEach can clean it up and parallel runs do not
collide.
- Around line 168-178: In the wait.PollUntilContextTimeout closures, prevent
short declarations from shadowing the outer imageStreamErr and imageStreamv2Err
variables: declare each output variable separately and assign the describe
result to the existing error variable. Apply the same fix to the corresponding
test path so failure messages receive the actual describe error.

Review comments at @test/extended/apiserver/admission_control.go:
- Line 86: In the closures, short declarations shadow the outer error variables,
leaving timeout failure messages without the actual errors. Update the
`namespaceErr`, `apperr`, `poderr`, and `chkNamespaceErr` assignments to reuse
their outer variables by declaring each output variable separately and assigning
with `=`; leave the already-correct `delerr` assignment unchanged.

Review comments at @test/extended/apiserver/admission_control.go:
- Line 263: In the `admission_control` setup, check and assert errors from the
`new-project` and both `apply` commands instead of discarding them; after
applying the CRD, wait for `testcrs.example.com` to become Established before
applying the custom resource. Reuse the existing `err` variable where
appropriate.
- Around line 101-102: Update the poll closures in the admission-control test to
assign errors to the captured namespaceErr, apperr, poderr, and chkNamespaceErr
variables instead of shadowing them with :=. Declare any accompanying output
variables separately so the captured errors retain the values used by the
failure messages.

Review comments at @test/extended/apiserver/audit_logging.go:
- Around line 203-205: Limit the audit log read in the node-logs invocation
within the audit logging test by adding a small --tail limit, reusing the
--tail=20 value used for this path elsewhere. Keep the existing output check and
command flow unchanged.
- Line 90: In the audit-configuration tests around the `APIServers().Get` call,
wait until the relevant API-server rollout has applied the requested policy
before asserting behavior, and wait again after restoring the original profile
before each test exits. Apply the same rollout checks to all four
audit-configuration tests.

Review comments at @test/extended/apiserver/quota.go:
- Around line 203-212: Update both polling closures that call
copyImageToInternelRegistry so a nil error returns an immediate error explaining
that the copy unexpectedly succeeded; keep the denied-output success condition
for expected failures and avoid waiting for the poll timeout.

Review comments at @test/extended/apiserver/admission_control.go:
- Around line 68-88: In the admission-control test around the patch readback,
assert the container image equals the full `:latest` image rather than merely
containing `hello-openshift`. Add a negative case using an API-supported update
path to make the merged object violate the configured LimitRange, and assert
that the request is rejected with a LimitRange-specific error.

Review comments at @test/extended/apiserver/admission_control.go:
- Around line 231-240: Update the role-removal poll assigned to errAdmRole to
check the get command error and retry when it fails, and trim rolebindingOutput
before comparing it with the admin rolebinding name. Keep the poll from
reporting completion until the admin role has been removed.

Review comments at @test/extended/apiserver/audit_logging.go:
- Around line 24-29: Update waitForAPIServerRollout and its callers to skip the
Progressing=True wait when the patch makes no spec change, while still waiting
for the completed rollout when a change triggers one. Determine whether the
patch changes the current spec before invoking the rollout wait, including
cleanup patches that restore an unchanged value.
- Around line 214-241: Update the OCP-68629 test body so it checks file
permissions, not just nonempty audit-log output. For each master, read the mode
of the audit log files in the relevant API server audit directories and assert
that each mode is no more permissive than 600; keep the existing master-node
iteration and HyperShift skip.

Review comments at @test/extended/apiserver/admission_control.go:
- Around line 77-88: In the admission-control test, replace the broad image
substring check with an exact assertion for the image set in step 5. Extend the
flow after the successful patch to submit a patch whose resource limit exceeds
the namespace maximum, and assert that admission control rejects it; use the
existing patch operation and limit configuration to target merged-object
validation.
- Around line 213-216: Replace the insecure http.Transport-based client
construction in the admission-control request path with an HTTP client
configured from the user’s rest.Config, preserving the 30-second timeout. Remove
the manual bearer-token header and oc whoami -t call so credentials are added by
the configured client only after the server certificate is validated.

Review comments at @test/extended/apiserver/audit_logging.go:
- Line 299: Replace the permissive mode regex in the audit log permission check
with octal parsing and a bitmask check that rejects any permission bits beyond
0600, while allowing more restrictive modes. Add the strconv import needed for
parsing.

Review comments at @test/extended/apiserver/quota.go:

oc.Run("get") fails, before trimming or counting output. Preserve the existing
handling of successful output.

Review comments at @test/extended/apiserver/admission_control.go:
- Around line 93-96: Update the error assertion in the patch test so it only
accepts a LimitRange resource-usage violation, not the generic forbidden error
caused by immutable Pod fields. Narrow the regexp in the test around
invalidResourcePatch to match the LimitRange maximum CPU or memory usage
message.

Review comments at @test/extended/apiserver/audit_logging.go:
- Line 179: Update both custom-rule tests near the customRules configuration so
they do not run with a top-level audit profile of None: explicitly skip that
configuration or set a non-None profile for each test and restore the original
profile afterward. Ensure the tests exercise the custom rules rather than only
asserting their configuration.
- Around line 44-45: Update all four audit-configuration cleanup functions to
create and use a fresh bounded context for the configuration read and restore
patch, rather than relying on the potentially canceled spec context; preserve
the existing restore behavior.
- Line 270: Handle the error returned by exutil.IsHypershift before using its
result to decide whether to skip; report or assert the error and avoid
proceeding to the master-node check when detection fails. Preserve the existing
HyperShift decision for successful detection.

Nitpick comments:
Review comments at @test/extended/apiserver/admission_control.go:
- Around line 199-201: Copy the config returned by
oc.KubeFramework().ClientConfig() with rest.CopyConfig before setting
restConfig.Timeout, at both affected client setup locations. Keep the timeout
change isolated to the copied config so it does not mutate the framework’s
shared configuration.

Review comments at @test/extended/apiserver/audit_logging.go:
- Around line 169-171: Update the custom-rule comparisons in both cleanup
functions so they do not discard json.Marshal errors; preferably compare
originalCustomRules and currentServer.Spec.Audit.CustomRules directly with a
deep comparison, or check and handle both marshal errors before comparing.
