Fixed Renovate pull requests being blocked by stale dist bundles - #167
Conversation
Renovate updates package.json and the lockfile but cannot run `pnpm build`, so any dependency that ends up inside an ncc bundle leaves the committed dist/ stale and fails the `git diff --exit-code` check in repo-ci.yml. The new workflow rebuilds the bundles and pushes them back onto Renovate's branch, using a GitHub App token because pushes made with GITHUB_TOKEN do not trigger workflow runs and would leave the PR stuck on a stale failing check. `pnpm build` now clears dist/ first, since ncc numbers its chunk files by content and stale chunks would otherwise accumulate. Repo CI push runs are limited to main so branch pushes are covered once, by the pull_request trigger. Claude-Session: https://claude.ai/code/session_01H42nL68xJCaEduHRWj1iYZ

The workflow handed the writable App token to actions/checkout with the default persist-credentials, so it sat in .git/config while pnpm install and pnpm build ran. The build executes ncc, a Renovate-updated dependency, so compromised build tooling could read and exfiltrate it. The repo is public, so checkout now takes no token and sets persist-credentials: false; the App token is minted only after the build and only when the bundles actually changed, then passed to git push via an authenticated remote URL from a step env var. Also added permission-contents: write so the minted token no longer inherits every permission the Renovate app holds on the installation (zizmor github-app, HIGH), and documented the job's contents: write.

Every open Renovate PR in this repository is permanently blocked, and has been for as long as each has been open (#125, #130, #142, #148, #166). Each one installs, lints, tests and builds cleanly, then fails on repo-ci.yml's
git diff --exit-code -- <action>/diststep. The cause is thatdist/is committed: Renovate updatespackage.jsonandpnpm-lock.yamlbut cannot runpnpm build, so any dependency that ends up inside the ncc bundle leaves the committed bundle stale. That failure blocks theRequired checks passgate, so the PR can never merge, and Renovate rebases it daily so it just stays red forever. The recently merged PRs (#161-#165) only got through because vite, oxlint and oxfmt never enter a bundle.The fix is a new
rebuild-dist.ymlworkflow that runs on Renovate's pull requests, rebuilds both actions and pushes the regenerateddist/back onto the branch, so the diff check has something current to compare against. It pushes with a GitHub App token from the existingTRYGHOST_RENOVATE_APP_ID/TRYGHOST_RENOVATE_APP_PRIVATE_KEYorg secrets rather thanGITHUB_TOKEN, because pushes made withGITHUB_TOKENdeliberately do not trigger workflow runs — repo-ci.yml would never re-run against the rebuilt commit and the PR would sit on a stale failing check. Since that means handing a real write token to a workflow triggered by a pull request, the job is guarded on both the author beingrenovate[bot]and the head branch living in this repository, so a fork PR can never reach it. Third-party actions are SHA-pinned.Two smaller things came out of the same investigation. Both
buildscripts nowrm -rf distfirst: ncc numbers its chunk files by content and never clears its output directory, so a dependency bump that renumbers a chunk orphans the old one, and I found four such stale files while rebuilding for the ncc 0.45.0 bump. And repo-ci.yml'spushtrigger is now scoped tomain— it previously fired on bothpull_requestandpush, which meant every PR ran the entire matrix twice.Verified locally on Node 22 with pnpm 10.34.5 (matching CI via corepack and the
packageManagerfield): actionlint is clean on both workflows, both actions pass install, lint, test (9 and 38 tests) and build, and a cleanrm -rf dist && pnpm buildreproduces main's committeddist/byte-for-byte, confirming the build is deterministic and that main itself carries no stale chunks.https://claude.ai/code/session_01H42nL68xJCaEduHRWj1iYZ
