ci: add docs-only no-op twin so required checks report on docs PRs - #478
Merged
Conversation
Docs-only PRs to main were structurally unmergeable: ci.yml path-ignores docs/** and markdown, so the ruleset-required contexts (lint, typecheck, test (1/3..3/3), editor-ux) never reported and mergeStateStatus stayed BLOCKED forever (hit on PR #477; same failure shape as the 0265 release-PR stall). Every docs PR needed gh pr merge --admin. Fix is GitHub's documented paired no-op pattern: ci-docs-noop.yml declares the SAME job names, triggered by paths: matching exactly what ci.yml ignores, with each job exiting 0. GitHub satisfies a required context from a passing check run of either workflow. Consumer (0294 policy) is the main ruleset itself; pass condition is decidable by construction. changelog-section is not twinned — changelog-check.yml has no paths filter and already reports on docs-only PRs. Both workflows carry KEEP IN SYNC comments pointing at each other. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Signed-off-by: xNet Test <test@xnet.dev>

Summary
Docs-only PRs to main were structurally unmergeable without
gh pr merge --admin: ci.yml path-ignoresdocs/**,*.md,**/*.md,.github/*.mdon thepull_requesttrigger, while the main-branch ruleset requires the contextslint,typecheck,test (1/3)–test (3/3),editor-ux, andchangelog-section. On a docs-only PR those workflows never run, the contexts never report, andmergeStateStatusstays BLOCKED forever — hit on #477, same failure shape as exploration 0265's release-PR stall.Fix
GitHub's documented paired no-op pattern ("Handling skipped but required checks"):
ci-docs-noop.ymlwith the SAME job names (lint,typecheck,testsharded1/3–3/3,editor-ux), triggered bypaths:matching exactly what ci.yml ignores; every job just exits 0. A required context is satisfied by a passing check run of that name from either workflow.changelog-sectionis not twinned:changelog-check.ymlhas no paths filter and already reports on docs-only PRs (fragment orskip-changeloglabel as usual).KEEP IN SYNCcomments pointing at each other so thepaths/paths-ignorelists don't drift.Per the 0294 policy: the named consumer is the main ruleset itself; the pass condition is decidable by construction (always green).
Verification
mergeStateStatusreaches CLEAN/UNSTABLE instead of BLOCKED (this PR touches workflows, so it runs the full real CI and can't exercise the docs-only path itself).🤖 Generated with Claude Code
