Problem

scripts/apply-rulesets.sh --all listed every non-archived org repo, including the temporary private forks GitHub creates for security advisories (<repo>-ghsa-<id>, for example TalkTerm-ghsa-pc5f-cw67-7cmm and .github-ghsa-qpjq-vrh6-8wcg). Reading rulesets on those forks fails with failed to resolve ruleset ID, so --all exited 1 with "5 repo(s) failed" even when every real repo succeeded.

--all would also create code-quality and pr-quality on software-factory and software-factory-canary. Neither repo has a dependency-audit workflow, so the required dependency-audit / Audit gate check would block every merge there.

Change

  • New function classify_fleet_repos. It flags a repo as a GHSA fork using the same check as the dev-lead retry sweep (fix(dev-lead-retry): an API error body no longer crashes the org sweep .github-private#2462): the name ends in a GHSA id, the repo is private, issues are off, and the parent repo exists in the org. A GHSA-shaped name on its own never causes a skip.
  • The listing now includes archived repos (gh repo list without --no-archived, --limit 1000), but only for the parent lookup. A fork whose parent was archived after the advisory opened is still recognised. Archived repos are never applied to, as before.
  • New readonly FLEET_EXCLUDE=(software-factory software-factory-canary), an explicit list chosen by the maintainer instead of probing each repo's workflows. An explicit --repo still applies to these repos. This PR doesn't change any live ruleset on them.
  • Every skipped repo gets a log line, for example [apply-rulesets] skip combsmith/TalkTerm-ghsa-pc5f-cw67-7cmm: GHSA temporary private fork. A failure on a real repo still fails the run.

Risk

Low. Only --all repo selection changes. --repo / bare-name mode, the ruleset payloads, the code-scanning floor and the declared-checks merge are unchanged. A wrong classification can have two effects:

  • A real repo is wrongly skipped. Then --all stops converging it, and the skip line shows that. To be flagged as a GHSA fork, a repo must have all four signals; the name alone is not enough.
  • A fork is wrongly applied to. That is the old behavior: --all exits 1.

Rollback

Revert the PR's commits on main. The script goes back to the plain --no-archived listing. No live state needs to be undone, because this PR changes no ruleset.

Monitoring

  • The next --all run (dry-run first) should exit 0. Its [apply-rulesets] skip ... lines should list only the GHSA forks and the two FLEET_EXCLUDE repos.
  • An exit code of 1 or an unexpected skip line is the signal to investigate.

Consumers of --all output

None found. I searched combsmith/.github, combsmith/.github-private and the other org repos (GitHub code search for apply-rulesets):

  • bootstrap-new-repo.sh calls the script with --repo.
  • apply-repo-settings-reusable.yml calls it with a bare repo name.
  • Every other reference is a doc or comment pointing at --repo.

Nothing parses the --all log output, the "across the fleet" line, or the "no repositories found" message. The --all mentions in standards/ are for fix-ruleset-bypass.sh --all, a separate script.

Verification

  • bats: 48/48 pass in test/scripts/apply-rulesets/. New cases:
    • GHSA forks are skipped and the run exits 0.
    • A GHSA fork with an archived parent is skipped, and the archived repo itself is not applied to.
    • A GHSA-shaped name alone never causes a skip.
    • A failure on a real repo still exits 1.
    • FLEET_EXCLUDE repos get no gh calls of any kind (the stub logs every call).
    • An explicit --repo still works on an excluded repo.
  • The new tests fail against the old script. The archived-parent case fails if --no-archived is restored.
  • shellcheck --severity=warning -x is clean.
  • Live ./scripts/apply-rulesets.sh --all --dry-run against combsmith exited 0. It skipped 5 GHSA forks and 2 FLEET_EXCLUDE repos and processed the 13 real repos.

🤖 Generated with Claude Code

`--all` listed every non-archived org repo, including the private
`<repo>-ghsa-<id>` forks GitHub creates for security advisories. Their
rulesets can't be read ("failed to resolve ruleset ID"), so --all exited 1
with "5 repo(s) failed" even when every real repo succeeded. Detect them as
combsmith/.github-private#2462 does: GHSA id suffix, private, issues off,
and parent repo present in the org.

Also add FLEET_EXCLUDE (software-factory, software-factory-canary): they
have no dependency-audit workflow, so code-quality's required Audit gate
check would block every merge. An explicit --repo still applies to them.

Summary

Summary by CodeRabbit

  • Bug Fixes
    • Fleet ruleset updates now skip configured exclusions and qualifying temporary GHSA forks, while continuing to process other repositories.
    • Explicitly targeting a repository still applies rulesets even if it is normally excluded from fleet updates.
    • Fleet updates now report errors when repository listing fails or no applicable repositories remain.

Fleet mode now classifies repositories using their settings and names, skips qualifying GHSA forks and configured exclusions, and applies rulesets to the remaining repositories. Explicit --repo targeting remains available for excluded repositories.

Changes: Fleet ruleset application

Layer / File(s) Summary
Fleet repository classification
scripts/apply-rulesets.sh, test/scripts/apply-rulesets/apply-rulesets.bats
The script defines FLEET_EXCLUDE and classifies GHSA forks using repository privacy, issue settings, name patterns, and matching parent names. Tests cover those conditions and verify that explicit --repo targeting still applies to excluded repositories.
Fleet execution and failure handling
scripts/apply-rulesets.sh, test/scripts/apply-rulesets/apply-rulesets.bats
The --all path requests repository metadata, skips GHSA forks and excluded repositories, and applies rulesets to other repositories. Tests cover iteration and ruleset failure handling.

Estimated code review effort: 2 (Simple) | ~15 minutes

dev-lead is withholding action on this item.

It is labeled dev-lead:hands-off (deliberately kept off-limits to dev-lead (e.g. changes to the dev-lead automation itself)), so dev-lead will not pick it up while that label is present. This notice is posted once so the withhold is visible rather than looking like a stalled run.

To re-enable automated pickup: remove the dev-lead:hands-off label.

The excluded-repo test checked $CALLS, which records only writes, so a read
against an excluded repo (e.g. a required-checks GET answered with a handled
404) would pass unnoticed. The stub now logs every call to $GH_LOG.

Summary

Both reviewers rated the risk MEDIUM and chose escalate, so they fully agree. Neither found a blocking logic defect in the new --all classification in scripts/apply-rulesets.sh. Both escalated on process gates: the PR description lacks the Risk, Rollback and Monitoring sections, and CodeQL Analyze (actions) was still in progress. Both also raised the same archived-parent edge case, which the rubber duck reported as a logic gap and added a missing-test note and an output-format-change integration note. Neither reviewer ran the code.

Cross-engine agreement

Findings

  • major: The PR description has Problem, Change and Verification sections but no Risk, Rollback or Monitoring sections. The deterministic safety check reports DESCRIPTION_MISSING: 3 and marks it [escalate]. Suggested content. Risk: only --all repo selection changes. Rollback: revert this commit. Monitoring: the [apply-rulesets] skip ... log lines and the exit code of the next --all run.
  • minor: CodeQL Analyze (actions) was IN_PROGRESS at head 16bd7b2. Every other completed check passed or was skipped. The merge state is BLOCKED pending an org-leads review.
  • minor: CodeRabbit's inline comment about the excluded-repo test appears to be fixed by commit 16bd7b2, because the stub now logs every call to $GH_LOG. Thread resolution state could not be confirmed.
  • minor: The parent-repo check uses the --no-archived listing. A GHSA temporary fork whose parent was later archived is classified apply, and --all fails again, which is the original bug. The failure is loud, not silent. Fixes: build the parent-name list from a listing that includes archived repos, or document the limitation.
  • minor: GHSA parent detection uses the --no-archived list. A fork whose parent was archived after the advisory fork was created is classified apply and fails the run with 'failed to resolve ruleset ID'. The 500-repo --limit has the same effect if the parent falls outside the page. Either list with archived repos for parent lookup only, or document the limitation.
  • minor: The test 'a GHSA-shaped name alone never skips a repo' has no case for a fork whose parent is archived, so that gap is untested. The FLEET_EXCLUDE test's RULESETS_FAIL='software-factory' would also match the canary repo, but the grep on GH_LOG is the real guard.
  • info: GHSA detection depends on the parent being among the first 500 repos returned. FLEET_EXCLUDE matches bare repo names whatever $ORG is set to. Neither matters at the current org size.
  • info: The deep reviewer traced the jq --args handling, the GHSA id alphabet, the parent-name sub, null handling for isPrivate and hasIssuesEnabled, and the empty-list guard under set -u. All looked correct. No shell was available, so shellcheck and bats results come from CI.
  • info: The new RULESETS_FAIL stub case sits after repo list and before /rulesets/. The rest of the stub could not be seen, so it is unconfirmed that RULESETS_FAIL fires on every rulesets read. The Apply Rulesets bats job passed in CI.
  • info: CI is not fully green: CodeQL is in progress, and some dev-lead runs were cancelled, likely superseded. The PR carries the dev-lead:hands-off label. Required checks could not be verified.
  • info: The --all output format changed. It now prints skip ... lines and uses a different empty-list error path. It was not checked whether any other workflow or script parses the output or the 'no repositories found' message.

Risk: MEDIUM
Reviewed commit: f9c133dba937ab11e74aafbe7e676c575890e6c7
Review mode: triage-approved (single reviewer)

Summary

This PR changes which repos scripts/apply-rulesets.sh --all applies to.

  • A new jq function, classify_fleet_repos, puts each repo in one of four groups: archived, ghsa, excluded or apply.
  • A repo counts as a GHSA fork only if all four checks pass. Its name must end in -ghsa-xxxx-xxxx-xxxx, using GitHub's GHSA id alphabet. It must be private, have issues off, and have its parent repo in the org listing.
  • The listing now includes archived repos (--limit 1000), so a parent that was archived later is still found. Archived repos are still never applied to.
  • FLEET_EXCLUDE (software-factory, software-factory-canary) is skipped under --all. An explicit --repo still applies to those repos.

I agree with the triage rating of MEDIUM, logic change. The --repo and bare-name paths, the ruleset payloads, the code-scanning floor and the merge of declared checks are all unchanged.

Linked issue analysis

No issue is linked. The PR description covers the problem, the change, the risk, rollback, monitoring, consumers of the --all output, and verification, so it is enough to review against. The PR fully addresses the problem it describes: --all exited 1 because of GHSA forks, and code-quality would be applied to software-factory*, whose merges it would block.

Findings

Prior review findings (16bd7b2), all resolved:

  • ✅ major, missing Risk/Rollback/Monitoring sections: the PR body now has all three, and the safety check reports DESCRIPTION_MISSING: 0.
  • ✅ minor, CodeQL Analyze (actions) still running: it is now SUCCESS, along with every other CodeQL check.
  • ✅ minor, parent lookup used --no-archived, so a fork of an archived parent was still applied to: fixed in f9c133d. The listing now includes archived repos and the limit went from 500 to 1000. Archived repos are classified first and are never applied to.
  • ✅ minor, no test for the archived-parent case: a new test, skips a GHSA fork whose parent is archived; never applies to archived repos, covers it. The stub now drops archived entries when --no-archived is passed, so the test would fail if the old listing came back.
  • ✅ minor, CodeRabbit's excluded-repo test comment: commit 16bd7b2 makes the stub log every gh call to $GH_LOG, and the test checks that no call names combsmith/software-factory. The CodeRabbit review is now DISMISSED.
  • ✅ info, consumers of the --all output: the PR body says a search found no consumers. bootstrap-new-repo.sh calls the script with --repo, and the reusable workflow calls it with a bare repo name. I could not run that search myself, so this is the author's claim and is unconfirmed.

New review of the current diff:

  • I traced classify_fleet_repos:

    • jq -r --args correctly passes FLEET_EXCLUDE in as $ARGS.positional.
    • The id alphabet [23456789cfghjmpqrvwx] matches GitHub's.
    • sub($ghsa; "") correctly gives the parent name, which is then looked up in the full name list, archived repos included.
    • == true / == false correctly treat null fields as not matching.
    • An empty list produces one empty line, which no case branch matches, and then the ${#repos[@]} guard returns the error.
    • Under set -u, "${repos[@]}" is only expanded after the count check.
    • A jq parse failure gets its own error and makes the run fail.

    I found no logic defects.

  • The tests cover the main cases: forks skipped with exit 0, a fork with an archived parent, the name alone never causing a skip (public, issues on, no parent, wrong alphabet), a real repo's failure still exiting 1, excluded repos making no gh calls, and an explicit --repo working on an excluded repo.

  • nit, not blocking: the log line [apply-rulesets] fetching non-archived repos in ${ORG} ... is now slightly wrong, because the call also fetches archived repos for the parent lookup. Consider rewording it, for example to "fetching repos in ...".

  • info: with --limit 1000, an org of more than 1000 repos would be cut off silently, and a fork whose parent falls outside the list would be applied to and fail loudly, as before this PR. The org is far below that size today.

  • info: SonarCloud reports 1 new issue and the quality gate passed. Its content was not available to me. CodeRabbit's docstring-coverage warning is advisory only.

  • Unconfirmed: the review-thread resolution state was not in the context I was given. The only actionable bot thread (CodeRabbit) was addressed in code and that review is DISMISSED. No human reviewer questions are open. The GitHub secret-scanning tool was not available. gitleaks CI passed.

  • I could not run shellcheck or bats myself; those results come from CI.

CI status

All checks completed: every one is SUCCESS, SKIPPED, or NEUTRAL (CodeRabbit). This includes Apply Rulesets Tests (Lint and bats), ShellCheck, Lint, CodeQL (actions, python), SonarCloud, gitleaks, Agent Security Scan, AgentShield, dependency-audit / Audit gate and duplicate-decl-gate. GitHub shows the merge state as BLOCKED only because a review from org-leads is required. The PR has the dev-lead:hands-off label.
