Why

The signed-commits rule appears active even though it covers no branches. That gives a misleading picture of the organization's protection.

What

Retain the existing rule as a disabled record with its complete settings preserved. Allow the controller only to observe and update that record, while keeping every effective branch protection in place and preventing recreation or deletion.

All ten repository tests and validation against the installed schema pass. All 99 resource identities remain, 98 resources are unchanged, and the safety check rejects 16 unsafe variations.

Fixes #132

Please review commit f6ebfe1, especially preservation of the existing ruleset and the restriction to observing and updating its disabled record.

@devantler Full review complete for commit f6ebfe1b1751b461d4424fc4052b903ebb4f749a.

P3 — Correct the stale ruleset policy comments

deploy/organization-rulesets/kustomization.yaml still states that all ten existing organization rulesets are Observe-only. It also lists require-signed-commits.yaml under “Adopted Observe-first (read-only).”

The manifest now grants Observe and Update to this one retained ruleset. The comments conflict with deploy/organization-rulesets/README.md and can cause an incorrect future policy change.

Update the header and resource-group comments to distinguish:

  • nine Observe-only imported rulesets;
  • the retained signing rule with Observe and Update;
  • three net-new managed rulesets.

The provider v0.19.1 CRD supports the changed fields. The manifest preserves external ID 5397812 and excludes Create, Delete, and LateInitialize. The signing-rule test also enforces these constraints. All available commit checks passed.

I could not independently compare the manifest with live ruleset 5397812. The available GitHub integration returned HTTP 403 for that organization-ruleset endpoint.

✅ Action performed

Full review finished.

Corrected the stale policy comments from the review in commit 4193a61. They now distinguish nine Observe-only imports, the retained disabled signing record, and three managed rulesets. The complete rendered configuration is byte-identical, and the focused safety check passes.

The live ruleset and its controller observation were independently compared with the proposed settings. The review service's unavailable organization endpoint does not leave that preservation check outstanding.

📝 Walkthrough

Walkthrough

The retained signing rule now uses Observe and Update, with enforcement: disabled and a complete backfilled specification. Documentation records the retirement model and retained identity. A new shell test validates the rendered object and its exact fields. CI and the maintenance checklist run this validation.

Priority: ⚪ Not assessed

Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to f6ebf

This change disables and retains the ineffective signing rule without allowing creation or deletion, but one adoption-guide statement still implies all existing rulesets are read-only. Clarifying that the retained signing rule is the Observe/Update exception would remove the remaining low merge-readiness risk.

Obtain the live ruleset before enabling Update.

The render test checks only the manifest. The live comparison for ruleset 5397812 is unavailable because gh api returned HTTP 403. Do not merge with Update enabled until the live fields match .spec.forProvider.

No findings.

The follow-up commit changes only comments in deploy/organization-rulesets/kustomization.yaml. The comments now correctly distinguish nine Observe-only imports, the retained disabled signing record with Observe and Update, and three net-new managed rulesets.

The retained require-signed-commits resource still uses external ID 5397812. It permits only Observe and Update. It remains disabled. It omits Create, Delete, LateInitialize, and initProvider.

tests/signing-rule-retirement.sh verifies the rendered resource identity, exact policy set, disabled enforcement, complete declared configuration, empty ref coverage, and expected rule fields. CI executes this test. All completed checks succeeded.

No findings.

The latest commit changes only the adoption guidance in deploy/organization-rulesets/README.md. The guidance now correctly scopes managementPolicies: ["Observe"] to the nine Observe-only imports. It identifies require-signed-commits.yaml as the exception with only Observe and Update.

The complete change retains ruleset 5397812. It sets enforcement: disabled. It declares an empty ref include list. It excludes Create, Delete, LateInitialize, and initProvider.

The kustomization comments and both documentation files consistently distinguish the nine Observe-only imports, the retained signing-rule record, and the three net-new managed rulesets.

tests/signing-rule-retirement.sh verifies the retained record’s identity, lifecycle policy, disabled state, declared configuration, and empty ref coverage. CI runs this test. All completed checks succeeded.
