In `@enhancements/storage/disable-force-detach-option.md`:
- Line 123: Remove the malformed “expectations).” fragment from the table, or
replace it with a valid five-column table row so the surrounding Markdown table
satisfies MD055 and MD056.
- Line 98: Update the “Risks and Mitigations” section in the
disable-force-detach documentation to describe the availability impact of
retaining the VolumeAttachment, required monitoring, and recovery through the
non-graceful node shutdown procedure. Replace the “Support Procedures” TBD
placeholder with the corresponding operational recovery steps.
- Line 15: Update the tracking link in the proposal to use STOR-2883, matching
the PR objective; only retain STOR-2789 if the document explicitly explains why
it is the correct issue.
- Around line 65-70: Update the ControllerManager example to use a yaml-labeled
fenced block and add metadata.name with the canonical value cluster, while
preserving the existing apiVersion, kind, and forceDetachOnTimeout settings.
- Line 46: Update the forceDetachOnTimeout proposal to define the RBAC
permission required for modifying ControllerManager.spec.forceDetachOnTimeout,
restricting updates to admin principals. Add an authorization test demonstrating
that non-admin principals are denied while authorized admins can change this
cluster-wide setting.
- Line 78: Update the HyperShift section of the force-detach option
documentation to define the reconciliation path: explain how
ControllerManager.spec.forceDetachOnTimeout reaches hosted KCM configuration
through the Control Plane Operator, or explicitly mark the option unsupported
for hosted clusters.
- Line 153: Align the documented empty-value behavior with API validation for
ControllerManagerSpec.ForceDetachOnTimeout: either add "" to the API enum and
corresponding validation tests so it is accepted as Enabled, or revise the
documentation to state that only an omitted field defaults to Enabled.

“loose data” to “lose data,” leaving the rest of the text unchanged.
- Around line 129-130: Update the ControllerManager scenarios for force-detach
behavior to document that the DisableForceDetachOnTimeout feature gate must be
enabled, including the DevPreviewNoUpgrade or explicit API-test configuration,
and state that the ControllerManager resource is unavailable when the gate is
disabled.
