Full details: No-Weak-CryptoExplanation PASS: The pull-request diff adds version parsing, IAM binding script generation, configuration tracking, and validation only. It introduces no MD5, SHA1, DES, 3DES, RC4, Blowfish, or ECB usage; no custom cryptographic implementation; and no secret or token comparisons. Changed Go files use only existing formatting, filesystem, GCP, SDK, and Cobra functionality. Full details: Container-PrivilegesExplanation PASS: The pull request changes only Go source and test files. The parent-to-HEAD patch contains no container or Kubernetes manifests and no occurrences of Full details: No-Sensitive-Data-In-LogsExplanation No explicit sensitive-data logging condition is introduced. The new stderr message logs only a GCP service-account identifier, and the new warning logs a resource type and resource name. These are cloud resource identifiers, not passwords, tokens, API keys, session IDs, or personal data. JWK data and configuration values are written to files or generated scripts, not logged. Other WIF and service-account identifier logs were already present. Full details: No-Hardcoded-SecretsExplanation PASS: The pull-request diff adds no hardcoded API keys, tokens, passwords, private keys, credentials, embedded-credential URLs, or base64 secret strings. The new code only reads JWK data from the updated WIF configuration and constructs IAM commands from configuration values. The only long alphanumeric matches are function identifiers, not secret literals. Full details: No-Injection-VectorsExplanation The PR adds a shell-injection vector in Resolution Shell-escape every dynamic argument before writing it to generated scripts.

In `@cmd/ocm/gcp/scripting.go`:
- Around line 383-387: Update the service-account processing around
updatedRolesByServiceAccount so entries present in originalWifConfig but absent
from updatedWifConfig generate removal commands for every project-level and
service-account-level role, rather than being skipped; ensure the service
account itself is deleted if required by the existing removal behavior.
In `@cmd/ocm/gcp/update-wif-config.go`:
- Around line 135-145: Validate the parsed versions in the declarative branch
handling UpdateWifConfigOpts.OpenshiftVersions before calling
wifBuilder.WifTemplates; if trimming and filtering leaves wifTemplates empty,
return an error instead of applying an empty template list, while preserving
normal behavior for valid versions.
In `@tests/wif_config_update_test.go`:
- Around line 325-341: Rename the test case under “Updating WIF config without
--versions flag” to describe that it uses the versions returned by the API and
prunes none, rather than claiming it re-adds all supported versions. Keep the
test setup and assertions unchanged.

Included review availability: Your plan provides up to 12 included reviews per hour; 11 remain after this review.
Add version pruning support to `ocm gcp update wif-config` command with
new `--versions` flag for declarative version management.
- Added `--versions` flag that accepts comma-separated list of versions
- Implemented declarative behavior: versions not in list are removed
- Updated `--version` flag to be additive (adds without removing others)
- Added validation rules:
- `--versions` requires `--mode=manual`
- `--mode=manual` requires `--output-dir`
- Cannot use both `--version` and `--versions` together
- Renamed `wifConfig` to `originalWifConfig` to track pre-update state
- Pass both original and updated configs to script generation
- Updated `versionFlagDescription` to clarify additive behavior
- Added `versionsFlagDescription` for declarative flag
- Added `OpenshiftVersions` field to `options` struct
- Implemented `pruneUnusedBindings()` function:
- Compares original and updated WIF configs
- Identifies roles removed during version pruning
- Generates `gcloud projects remove-iam-policy-binding` commands
- Handles both predefined and custom roles
- Supports resource-scoped bindings
- Updated `generateUpdateScriptContent()` signature to accept both configs
- Fixed `createUpdateScript()` to pass original config for pruning
- Created comprehensive test suite covering:
- Flag validation (4 test cases):
- `--versions` with auto mode (should fail)
- `--versions` without `--output-dir` (should fail)
- Both `--version` and `--versions` (should fail)
- Manual mode without `--output-dir` (should fail)
- Version pruning scenarios (3 test cases):
- Remove v4.19: Updates from v4.19,v4.20,v4.21,v4.22 to v4.20,v4.21,v4.22
- Keep only v4.21: Updates from all versions to v4.21 only
- Add v4.20 and remove v4.19: Simultaneous add/remove operations
- Each pruning test verifies:
- Correct `add-iam-policy-binding` commands for target versions
- Correct `remove-iam-policy-binding` commands for pruned versions
- Pruning section header present in script
- Removed versions not in add commands
- Tests use temporary directories with automatic cleanup

In `@cmd/ocm/gcp/scripting.go`:
- Around line 370-375: The updatedRolesByServiceAccount comparison must track
each role’s complete effective binding identity, including role resource type
and binding target, rather than only RoleId(). Update
updateServiceAccountScriptContent and pruneUnusedBindings so bindings whose
effective identity is absent from the updated configuration emit removal
commands, including project-to-resource and resource-to-resource transitions,
and add coverage for both cases.
- Around line 386-389: Validate that no existing service account is omitted from
the updated WIF configuration before invoking WifConfig.Update().Send(), rather
than detecting removal inside createUpdateScript or pruneUnusedBindings.
Preserve the existing unsupported-operation error behavior, and prevent the
remote update unless the transition passes validation.
