Change and reason

Three follow-ups to #285. One of them is a correction of a mistake #285 made, which is the main reason this exists.

1. Declared lanes are not drift — and #285 got this wrong

The deed (MetaManifold-WebUI_chora.deed, routing :upstream-candidates "upstream/*") declares upstream/* a lane: work destined for the upstream remote, squash-merged there (notes/commit-signing.md records #192 landing that way). CONTRIBUTING.md declares archive/* and governance-badges. The triage in #285 classed branches by commit graph alone, so it reported upstream/placement-evidence as salvage — a class whose documented remedy is "close it, or re-apply it elsewhere" — and #270 was closed with it.

Deleting a laned branch discards a routing decision, not a commit. The content is recoverable (refs/pull/270/head), but the lane is gone and re-cutting it is the owner's call. So:

• lanes are read from the deed (with upstream/* as the fallback for a bare clone that has no deed checked out) plus the two documented in CONTRIBUTING.md;
• the triage prints a LANE column and counts laned branches separately;
• a laned branch does not raise --fail-on unless --include-lanes is passed;
• branch-hygiene.yml now takes its counts from the triage's own summary lines instead of grepping table rows (which would have broken the moment a column was added, and would have counted lanes as drift), and the issue body says how many laned branches it is deliberately not counting.

Corrected in the docs under Declared lanes are not spare branches, with decision 5 recording what to do about that candidate.

2. Dependabot PRs would have gone red for the wrong reason

Dependabot does not rebase by default. With two open updates, the second goes behind main the moment the first merges, and the new Branch freshness check fails a one-line dependency bump for a rule the bump did not break. Both ecosystems now set rebase-strategy: auto, so red on that check means what it says: a conflict a person has to resolve.

3. Pins and template

• actions/checkout was v4.4.0 in the standards job and v7.0.1 in five others; the occupancy job's copy carried no version comment at all, which makes Dependabot's diff for it unreadable. All six now match.
• The PR template names the Branch freshness check and the local command.

Also: a new "Looks wrong, is not" section

JoshuaJewell/MetaManifold-WebUI appears in README.md badges, CITATION.cff, the Codecov slug, CONTRIBUTING.md, frontend/src/about.ts and SECURITY.md. In the last pass I reported that as a stale owner to be "fixed" to hyperpolymath. That was wrong: it is the upstream this repository forks, recorded in 0-AI-MANIFEST.a2ml, the deed (:fork-of, :upstream) and must.k9.ncl (upstream_repository). Repointing the Codecov slug would send uploads at a project that may not have the token — and with fail_ci_if_error: false nobody would notice. Nothing in this PR touches those references; the doc now says why not, next to the standards-pin note and the docs/ whitelist.

Validation

Run here, on this branch, against the merged tree:

bash scripts/tests/test-triage-branches.sh        # 24 passed, 0 failed
bash scripts/tests/test-check-pr-freshness.sh     # 12 passed, 0 failed
bash scripts/check-governance-contract.sh         # 70 checks passed
bash scripts/tests/test-governance-contract.sh    # all mutations rejected
bash scripts/tests/test-scanner-boundaries.sh     # ok
bash scripts/tests/test-ci-logging.sh             # ok
bash scripts/lint-sonar-reliability.sh            # OK: no S2871 or S7758 in frontend/src

The triage tests now also cover: a lane declared in the deed is recognised; the deed pattern replaces the built-in fallback; without a deed the fallback still lanes; laned branches alone do not raise --fail-on (and --include-lanes reproduces the match); the JSON carries lane as a string or null. Every workflow was parsed as YAML, its embedded shell extracted and checked with bash -n, and the rolling-issue upsert exercised against a stub gh (create, update, close, and now the laned-branch paragraph).

Not run: the Julia and frontend suites — this diff touches no Julia or TypeScript, and neither runtime exists in the sandbox. scripts/ci/check-shell-secrets.sh refuses on a shallow clone, so it was not run here either; CI runs it on a full clone.

Scope

• The standards SHA pins stay as they are. Some are contract-bound (c6d78606… for K9/secret-scanner/Scorecard, 01c9b0c9… for the verdict-grid renderer), so reconciling them has to move scripts/check-governance-contract.sh's constants and the allowlist digest together. Recorded as decision 6.
• The Branch freshness ruleset entry is still an owner action.
• No lockfile, dependency, generated or vendored file changes; no renv.lock, Manifest.toml or tool_versions.yml edits.

Contribution checks

• I followed CONTRIBUTING.md.
• This branch starts at current upstream main and contains no merges from fork main (merge base 4b05b4b).
• CI has run and passed for this branch (see checks).
• Existing licensing, citation and acknowledgement text is unchanged.

📝 Summary

Summary by CodeRabbit

• New Features
  • Branch triage now identifies declared upstream and archive lanes, plus governance-badges, and includes lane information in its reports.
  • By default, branches in these lanes are excluded from --fail-on matches; use --include-lanes to include them.
  • Branch freshness checks are documented, including how to run a check manually.
  • Dependabot is configured to rebase pull requests automatically.
• Documentation
  • Updated repository guidance explains branch lanes, triage behaviour, and maintenance decisions.

Branch triage now identifies declared branch lanes, includes lane data in its output, and excludes laned branches from --fail-on matching by default. Tests, workflow reporting, repository guidance and configuration are updated to reflect these changes.

Changes: Repository hygiene

Layer / File(s)	Summary
Branch lane classification and output scripts/maintenance/triage-branches.sh, scripts/tests/test-triage-branches.sh	The triage script identifies configured upstream patterns and fixed lanes, reports lane values, and adds --include-lanes to --fail-on matching. Tests cover output formats, pattern fallback and failure behaviour.
Branch hygiene reporting and guidance .github/workflows/branch-hygiene.yml, CONTRIBUTING.md, docs/maintenance/repository-hygiene.md, .github/pull_request_template.md	The workflow reports declared-lane totals. Contribution and maintenance guidance describes lane handling and records related repository decisions. The pull request template adds branch freshness instructions.
Dependency and checkout configuration .github/dependabot.yml, .github/workflows/ci.yml, docs/maintenance/repository-hygiene.md	Dependabot configurations set rebase-strategy: auto. The standards checkout pin changes to v7.0.1; the occupancy pin receives a version comment. The maintenance document records the Dependabot setting.

Merge Risk: Moderate · up to c03f0

The new lane handling does not fully reach the branch-hygiene workflow. A repository with only declared-lane branches would still have its drift issue kept open, which defeats the fix. The CI checkout steps also keep the workflow token available to checked-out code. Fix both before merging; the remaining items are documentation corrections.

Correct the Dependabot default statement.

The comment says that Dependabot does not rebase by default. GitHub documents automatic rebasing as the default; rebase-strategy: disabled turns it off. (docs.github.com)

Keep rebase-strategy: auto if the repository wants this policy to remain explicit, but update the comment.

Suggested correction

-    # Dependabot's default is not to rebase, so with more than one open update
-    # at a time every one but the first would show red for the wrong reason.
-    # Rebasing makes the freshness check mean what it says: red here is a
-    # conflict that needs a person.
+    # Keep automatic rebasing explicit so the Branch freshness check can
+    # distinguish a rebasable update from a conflict that needs a person.

Count unlaned branches before deciding whether to keep the issue open.

If only an upstream/* or archive/* salvage branch remains, the Markdown summary still reports it in the salvage class total. SALVAGE is therefore non-zero, so Line 86 creates or retains the rolling drift issue. The separate LANED total cannot correct this because it does not distinguish stale from salvage. Derive the issue-triggering counts from rows with no lane, or add separate unlaned class totals to the triage output.

L1: 
L2: # Checkout v7
L3: ## What&#39;s new
L4: - Safer fork pull request handling: checkout now refuses to check out fork pull request code by default when the workflow is triggered by `pull_request_target` or `workflow_run`. These triggers run with the base repository&#39;s `GITHUB_TOKEN`, secrets, and runner access, where executing a fork&#39;s code commonly leads to &quot;pwn request&quot; vulnerabilities.
L5:   - To opt in after [reviewing the risks](https://gh.io/securely-using-pull_request_target), set the new `allow-unsafe-pr-checkout: true` input.
L6: - Migrated `actions/checkout` to ESM to support new versions of the `@actions/*` packages.
L7: - Updated direct and transitive dependencies, including security fixes for known vulnerabilities.
L8: # Checkout v6
L9: ## What&#39;s new
L10: - Improved credential security: `persist-credentials` now stores credentials in a separate file under `$RUNNER_TEMP` instead of directly in `.git/config`
L11: - No workflow changes required — `git fetch`, `git push`, etc. continue to work automatically
L12: - Running authenticated git commands from a [Docker container action](https://docs.github.com/actions/sharing-automations/creating-actions/creating-a-docker-container-action) requires Actions Runner [v2.329.0](https://github.com/actions/runner/releases/tag/v2.329.0) or later
L13: # Checkout v5
L14: 
L15: ## What&#39;s new
L16: 
L17: - Updated to the node24 runtime
L18:   - This requires a minimum Actions Runner version of [v2.327.1](https://github.com/actions/runner/releases/tag/v2.327.1) to run.
L19: # Checkout v4
L20: 
L21: This action checks-out your repository under `$GITHUB_WORKSPACE`, so your workflow can access it.
L22: 
L23: Only a single commit is fetched by default, for the ref/SHA that triggered the workflow. Set `fetch-depth: 0` to fetch all history for all branches and tags. Refer [here](https://docs.github.com/actions/using-workflows/events-that-trigger-workflows) to learn which commit `$GITHUB_SHA` points to for different events.

L30: We continue to focus our resources on strategic areas that help our customers be successful while making developers&#39; lives easier. While GitHub Actions remains a key part of this vision, we are allocating resources towards other areas of Actions and are not taking contributions to this repository at this time. The GitHub public roadmap is the best place to follow along for any updates on features we’re working on and what stage they’re in.
L31: We are taking the following steps to better direct requests related to GitHub Actions, including:
L32: 
L33: 1. We will be directing questions and support requests to our [Community Discussions area](https://github.com/orgs/community/discussions/categories/actions)
L34: 
L35: 2. High Priority bugs can be reported through Community Discussions or you can report these to our support team https://support.github.com/contact/bug-report.
L36: 
L37: 3. Security Issues should be handled as per our [security.md](security.md)

Disable credential persistence for these checkout steps.

The pull_request workflow grants contents: read and runs code from the checkout. actions/checkout persists the GitHub token unless disabled. An untrusted pull request can read that token. The standards job can then include it in an uploaded artefact. Set persist-credentials: false unless a later step requires authenticated Git operations.

Suggested correction for both steps

+          persist-credentials: false

Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Correct the claim that no other closed branch was in a lane.

The measurement table records archive/pre-sync-2026-10-17 as closed and deleted, while the new lane table defines archive/* as a declared lane. Amend the historical account to acknowledge that archive branch and distinguish its disposition from the upstream candidate’s.

GitHub documents rebase-strategy: auto as the default, not a new behaviour enabled by this setting. Automatic rebasing also does not guarantee that a non-conflicting update moves to the current main immediately after another update merges. State that the setting makes the default explicit; do not present it as a guarantee that every update will satisfy Branch freshness without intervention. (docs.github.com)

Review comment at @docs/maintenance/repository-hygiene.md at line 73:
Update the Dependabot explanation in the `.github/dependabot.yml` table entry to
say `rebase-strategy: auto` makes GitHub’s default behaviour explicit. Remove
the claim that rebasing guarantees Branch freshness without intervention;
clarify that automatic rebasing does not ensure every update moves to the
current `main` after another update merges.

Call badge-data a lane, not a class.

The triage script assigns governance-badges the badge-data lane and the unrelated class. Change “classes it badge-data” to “assigns it the badge-data lane” so this decision preserves the distinction introduced above.

Update the wording about `governance-badges` to say the triage script assigns it
the `badge-data` lane, not that it classes it as `badge-data`; retain the
separate `unrelated` class distinction.
