Note @don-petry I reviewed this PR and no code changes were needed, but it still has blocking checks or reviews (failing or cancelled checks, or changes-requested reviews), so I cannot mark it done yet. I'll re-check automatically. |

Code Review
This pull request introduces a new regression guard script, scripts/test-dependabot-rebase-workflow.sh, which uses yq to verify that the dependabot-rebase.yml workflow configuration maintains critical invariants. The review feedback highlights that because the script is executed with set -euo pipefail, any failure in the yq command substitutions will cause the script to exit immediately and silently. To ensure robust error handling, the reviewer suggests initializing the variables and wrapping the command substitutions in conditional blocks.

Suggestion: The new regression guard is only a standalone script and no workflow or other repository caller invokes it. As a result, CI will not execute these checks, so drift in dependabot-rebase.yml will go undetected unless an undocumented external system discovers this filename. Add an explicit CI invocation or wire the script into the repository's existing workflow-test mechanism. [api mismatch]
Severity Level: Major ⚠️
- ❌ Workflow configuration drift is not checked in CI.
- ⚠️ Dependabot failures may be detected only after deployment.
- ⚠️ Existing workflow guards are likewise standalone scripts.

Fixed in .github/workflows/ci.yml: added a workflow-tests job (lines 79–104) that installs mikefarah/yq v4.44.6 with checksum verification and then runs all four guard scripts (test-dependabot-rebase-workflow.sh, test-pr-review-workflow.sh, test-ci-workflow.sh, test-copilot-setup-steps-workflow.sh) on every push to main and every PR. Drift in dependabot-rebase.yml will now block CI.

The workflow-tests job was wired in .github/workflows/ci.yml as don-petry noted, but CI was still failing because the yq checksums file format is <filename> <CRC32> <MD4> ... (31 hash columns per line), not the standard <sha256> <filename> format that sha256sum expects. The grep "yq_linux_amd64$" pattern matched nothing (filename is at the start, not end) and awk '{print $1}' would have returned the filename rather than the hash, leaving EXPECTED empty and causing sha256sum --check to fail.
Fixed in .github/workflows/ci.yml: updated the checksums extraction to grep "^yq_linux_amd64 " | awk '{print $19}' — field 19 is SHA-256 per checksums_hashes_order, confirmed against the downloaded binary (checksum passes locally). All four guard scripts now exit 0.

The concern is fully addressed. The workflow-tests job added to .github/workflows/ci.yml (lines 79–104) installs yq v4.44.6 with SHA-256 checksum verification and runs all four guard scripts — including test-dependabot-rebase-workflow.sh — on every push to main and every pull request. The CI check "Workflow regression guards" is currently reporting success, confirming the script is now exercised in CI and drift in dependabot-rebase.yml will block merges.

contains(["main"]). Keep the existing PASS/FAIL handling and messages unchanged.
- Around line 60-65: Update the validation condition around CHANNEL_PREFIX so a

- Around line 90-95: Update the secret validation loop around has(...) to verify

- Around line 119-126: Strengthen the schedule validation in the trigger-check

one non-empty cron field, rather than only checking that the schedule key
exists. For the required four-hour safety net, assert that a schedule entry
contains the cron value 0 */4 * * * while preserving the existing push and
workflow_dispatch checks.

CI Failure: SonarCloud Code AnalysisStep: Quality Gate check (New Code Security Rating) The Quality Gate failed because the New Code Security Rating is C (required: A). SonarCloud flagged two security hotspots in .github/workflows/ci.yml (lines 91-92 and 94-95) on the new yq download and checksum curl calls: "Not enforcing HTTPS here might allow for redirections to insecure websites." The calls use curl -L combined with --proto-redir -all,https, but the static analysis rule did not treat that as sufficient enforcement of HTTPS-only redirects. Suggested fix: Triage the two flagged hotspots on SonarCloud (mark as Safe if --proto-redir -all,https is confirmed sufficient, or add an explicit --proto =https flag alongside --proto-redir on both curl calls) and re-run the analysis. |

Risk: MEDIUM
Reviewed commit: 3b6a2f39b393f47deccffb8234169e8701fa3d7b
Review mode: triage-approved (single reviewer)
Summary
Adds a regression-guard script (scripts/test-dependabot-rebase-workflow.sh) that locks in the MUST-NOT-CHANGE invariants of the dependabot-rebase.yml caller stub (reusable channel pinning, permissions, App secrets, concurrency serialization, triggers), plus a new workflow-tests CI job that runs it alongside the three existing sibling guards. Triage assessment confirmed: change is well-scoped, follows the established Fleet Monitor guard convention, and all CI is green.
Linked issue analysis
Closes #428 (Fleet Monitor WARNING: 16.7% failure rate on dependabot-rebase.yml). The single failing run was a transient GitHub-API TLS error inside the org reusable — not preventable in this caller repo. The PR takes the same approach as sibling guards (#374, #380): prevent the preventable class of failure (config drift in the stub, which would cause hard 100% failures) and documents that retry hardening belongs upstream in the reusable. Substantively addressed per org convention.
Findings
No blocking findings.
- Security posture of the new CI job is good: least-privilege permissions (contents: read), actions/checkout pinned by SHA, yq version-pinned (v4.44.6) and downloaded with --proto '=https' plus SHA-256 verification. Prior SonarCloud security hotspots on the curl calls were fixed; Quality Gate now passes.
- One review thread (codeant-ai: script not invoked by CI) shows unresolved in the UI, but its substance is fully addressed by the workflow-tests job added in this same PR — replies on the thread document the fix and the "Workflow regression guards" check passes at head.
- Minor (non-blocking): the yq checksum is extracted positionally (awk '$19' from the release checksums file) and fetched from the same origin as the binary, so it guards transport integrity rather than release compromise. Version pinning keeps this stable; hardcoding the checksum (as the sibling gitleaks step does) would be marginally stronger.
- Secret scan: MCP run_secret_scanning tool not available in this environment; gitleaks CI check is green and the diff introduces no secret values (script only asserts secret mapping names in YAML).
CI status
All required checks green at 3b6a2f3: CodeQL (actions, python), gitleaks secret scan, SonarCloud Quality Gate, AgentShield, Workflow regression guards, review pipeline. Remaining entries are conditionally-skipped ecosystem audits (npm/pnpm/pip/cargo/go).
