Suggested reviewers: Merge Risk: 🟠 High · up to The webhook server does not build at this head because of duplicate imports, so it cannot be released until those are removed. On OpenShift, both the operator and the webhook can also hang during startup if the API server stalls while its TLS settings are being read. Fix the build error before merging, and preferably add a startup timeout to that read. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@controllers/workspace/devworkspace_controller.go`:
- Line 99: The APIServer RBAC rule restricts list/watch to resourceNames=cluster
while SecurityProfileWatcher.SetupWithManager watches without a matching field
selector. Remove resourceNames=cluster from the list/watch rule, then regenerate
the affected manifests in
controllers/workspace/devworkspace_controller.go:99-99,
deploy/deployment/openshift/combined.yaml:27927-27936,
deploy/deployment/openshift/objects/devworkspace-controller-role.ClusterRole.yaml:138-147,
and deploy/templates/components/rbac/role.yaml:136-145; no selector change is
needed.
In `@main.go`:
- Around line 120-122: Replace the unbounded context.Background() passed to
BuildServerTLSOptions in main.go lines 120-122 and webhook/main.go lines 96-98
with a finite startup context, ensuring both TLS profile bootstrap entry points
time out and can reach the documented fallback.
In `@TLS_ADHERENCE_TEST_PLAN.md`:
- Around line 13-19: Update Test 1 and the corresponding sections around the
later referenced ranges to consistently expect LegacyAdheringComponentsOnly
after removing spec.tlsAdherence. Define that default value explicitly, then
align the verification command, expected logs, and results table with it.
- Around line 90-98: Update the TLS adherence test steps around the restart
checks to capture the current pod name before each profile patch, then wait for
a different ready pod after the restart. Inspect the pre-patch pod’s logs for
the watcher message “TLS security profile changed; initiating graceful restart,”
and inspect the replacement pod’s logs separately for the applied minTLSVersion
value.
- Around line 30-31: Update the legacy-path watcher expectations in
TLS_ADHERENCE_TEST_PLAN.md: after successful API server value retrieval sets
profileFetched=true, RegisterSecurityProfileWatcher registers the watcher even
when TLS options are not required. Remove or replace the “Skipping TLS profile
watcher (profile not applied)” examples and revise Test 5 and the referenced
notes to state that the watcher is running; retain skipping behavior only for
failed profile fetching.
- Line 63: Update the fenced code block in TLS_ADHERENCE_TEST_PLAN.md around the
referenced log fragment to specify the text language, resolving the Markdownlint
MD040 warning without changing the block contents.
In `@webhook/main.go`:
- Around line 35-40: Reorder the imports in the webhook package so configv1
appears in the third-party/Kubernetes group before the project-local tlssetup,
version, server, and workspace imports, preserving the three groups separated by
blank lines.

In webhook/main.go, the old signal handling via os/signal and syscall.SIGTERM is removed and replaced with the cancellable context pattern. The old code created a shutdownChan that was never actually wired to stop the manager, so this looks like a bug fix on top of the TLS work. Do you think that this should be called out explicitly in the PR description?
Other than that it looks good to me.
