Document the Dependabot Self-Hosted-Runners Account Setting - #1022
Merged
Conversation
Per issue #1015: an account-wide GitHub setting, 'Dependabot on self-hosted runners' at https://github.com/settings/security_analysis, routes Dependabot's own update jobs to a self-hosted runner pool. With no self-hosted runner registered, those jobs queue forever and are cancelled after 24 hours, with no visible failure in the Actions API or in ordinary CI, only a 'Self-hosted runner unavailable' message on the repo's own Dependabot page. GitHub never routes a public repo through this setting, so a public repo cannot show the symptom. Add the mechanical audit signal to AUDIT.md section 6 (a repo whose dependabot-updates/update-graph runs are all cancelled with zero steps), and a stand-up-time check to STANDUP.md section 4 for private repos, per the reporter's own suggested locations. Fixes #1015

maintainers of each private repository to identify its owner and inspect the
applicable repository or organization Dependabot setting, specifically the
Runner type. Remove guidance to disable “Automatically enable for new
repositories,” since it does not control runner selection.

In `@AUDIT.md` at line 119, Update AUDIT.md lines 119-119 and STANDUP.md lines
209-209 to distinguish Actions API evidence—completed runs expose conclusion:
cancelled and workflow-job endpoints expose job steps—from Dependabot-page
diagnosis; replace the claim that nothing surfaces in the Actions API, while
retaining “Self-hosted runner unavailable” as the Dependabot-page diagnosis.
Apply the same fix in `@AUDIT.md` at line 119: The same qualification from proof
to investigation signal applies to the stand-up guidance.

Per review on PR #1022 (CodeRabbit): AUDIT.md's own opening sentence already names the cancelled-with-zero-steps pattern as the mechanical signal, then a later sentence claimed 'nothing about it surfaces in the Actions API' - directly contradicting itself. Reworded to state that pattern is the only Actions-API-visible signal (not an explicit cause), matching what the doc already said. Same fix in STANDUP.md, which did not have the contradiction but had the same imprecise claim. Also: register a matching self-hosted runner is the alternative to disabling the toggle, if self-hosted routing is wanted, added to both docs rather than presenting disabling as the only fix.

- Line 119: Separate the manual “Check for Updates” action from the read-only
audit guidance in the Dependabot remediation section of AUDIT.md. Keep the audit
limited to reporting affected repositories, and place the rerun action in a
clearly labeled, separate post-audit remediation step.
- Line 119: Update the Dependabot unavailable-runner wording in AUDIT.md lines
119-119 and STANDUP.md lines 209-209 to consistently say jobs are “queued for up
to 24 hours” before cancellation; make the corresponding documentation-only
change at both sites.
In `@STANDUP.md`:
- Line 209: Update the affected-repository guidance in STANDUP.md to include
manually triggering the “Check for Updates” action after correcting the
Dependabot self-hosted-runner setting, since existing queued runs will not
restart automatically.

AUDIT.mdSTANDUP.md
Included review availability: Your plan provides up to 10 included reviews per hour; 1 remains after this review.
Per review on PR #1022 (CodeRabbit): AUDIT.md's Dependabot bullet mixed the read-only detection signal with the manual toggle/Check-for-Updates remediation in one breath, against this same file's own read-only-audit-then-separate-convergence structure (AUDIT.md section 10's own opening line). The account- setting fix has no PR to open (it is a GitHub UI toggle, not a repo file), so it does not fit section 10's PR-based convergence loop, but the bullet now explicitly marks where detection ends and the separate manual remediation begins. Also precision: 'queue forever and get cancelled after 24 hours' read as an exact duration. Changed to 'queue for up to 24 hours, then get cancelled' in both docs. STANDUP.md covers a repo standing up from nothing 'or a partial state' per its own opening line, so an already-partial repo can carry Dependabot jobs queued before this check ever ran. Fixing the toggle alone does not rerun those; added the same manual Check for Updates note AUDIT.md already had.

Per review on PR #1022 (CodeRabbit): 'dependabot-updates and update-graph workflow runs are all cancelled' read as requiring both workflow names present and cancelled, which could make the audit skip a repo carrying only one of the two. Changed to or, matching the actual detection intent: either workflow's runs being all-cancelled is the signal.

Promotes six merged PRs from this session: - #1021: Fixes #1017 - `hub_last_change()`/`_git_revisions()` read whatever branch ROOT is on, not `main`. Fixed by fetching and resolving `origin/main` fresh, and extended to `canonical_blob_sha()`, canonical-content reads, and `hub_tracked()` (file-set enumeration), each caught by review as the same class of bug. - #1022: Fixes #1015 - documents the account-wide "Dependabot on self-hosted runners" setting in AUDIT.md and STANDUP.md. - #1023: Fixes 4 of `#928`'s 12 findings (real bugs in newly-packaged Skills content). - #1024: Addresses `#669` - marks the `pyproject.toml` divergence-ledger gap as tracked back to the issue, since 2 of the 3 named entries had already converged independently. - #1025: Fixes `#1001` - regenerates `reports/workflow-reuse.md` against current fleet state. - #1026: Fixes #928's remaining findings (5-8), closing out the issue. All six reached `mergeStateStatus: CLEAN` with 0 unresolved review threads before merging. 🤖 Generated with [Claude Code](https://claude.com/claude-code) <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Documentation** - Clarified title-case, formatting, line-ending, .NET, Python, repository setup, and skill lifecycle guidance. - Added profile-specific Python testing and tooling instructions. - Documented nullable reference enforcement and XML documentation requirements for .NET projects. - Added guidance for Dependabot self-hosted-runner configuration and remediation. - **Bug Fixes** - Improved recursive file-format coverage and conflict verification examples. - Enhanced audit accuracy by consistently checking the remote main revision. - **Reports** - Refreshed repository divergence and workflow reuse metrics. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
