strict-authoring-face-8345 test walks the repo with an unguarded readFileSync and races tsup temp bundles (queue flake) #30256
Description
domain:ui#3 · os-justin · session_01QSeKYpFBMr917PmVkG9up7
Filing gate: ① (a test defect with a named site and a CI reproduction; it can red the merge queue for any PR).
Business reason
The merge queue runs the full suite, and every red queue build rebuilds every PR queued behind it. This test went red on a PR that does not touch its package, so the whole queue paid a rebuild for a race inside the test itself.
Reproduction
Queue build https://github.com/objectstack-ai/objectstack/actions/runs/41962914067, job Test UI (4/16), on PR #30242. That PR touches only ui/packages/app-shell and ui/packages/plugin-list:
FAIL unit packages/types/src/__tests__/strict-authoring-face-8345.test.ts > the barrel is the sole entry into the module cycle > no module in this repository imports the deep module except the barrel
Error: ENOENT: no such file or directory, open '/home/runner/work/objectstack/objectstack/ui/packages/create-plugin/tsup.config.bundled_xhmfdr22t5.mjs'
Site
ui/packages/types/src/__tests__/strict-authoring-face-8345.test.ts:546-553 on origin/main. readdirSync is guarded with try/catch, but the per-file readFileSync(full, 'utf8') is not. tsup writes and deletes a transient tsup.config.bundled_*.mjs beside a package's config while another shard builds. The walker lists the file, and it is gone before the read.
Same family (closed)
#20225 (check-error-status-conformance.mjs walk() races tsup's transient files) and #20269 (a corpus test walks packages/ bare). Those fixes guard the read, or skip tsup.config.bundled_*. This is a new site of the same family.
Reader who acts
Triage routes this card. The file is a ui package test, so the expected lane is domain:ui. The fix is one guard in the walker; the assertion must not be weakened.
Dedupe (open and closed)
strict-authoring-face-8345 is:issue: 17 hits, none about this walker. tsup.config.bundled ENOENT is:issue: 7 hits, the closed family above. New site.
