The `--maxWorkers=2` fix from the previous commit was falsified by real CI:
run 34574847774 still ended with `[vitest-pool]: Worker forks emitted error /
Worker exited unexpectedly` while reporting 126 of 127 files passed and zero
FAIL lines. The worker that died was the one running
tests/native-surface.spec.ts — it produced NO results at all, which is the
same shape as the two earlier crashes (125/126 and 123/124: N-1 files
reported plus a silent worker exit at teardown).
So the consistent signature across all four crashes is a worker-recycling
race, not a test failure. `test:windows` now runs the whole suite in ONE fork
(`--maxWorkers=1`), which removes recycling entirely; the cost is wall-clock
(14 s -> 41 s locally, and the Windows step stays well inside its 30-minute
budget) and the signal is unchanged. Retries are still deliberately not used —
they would hide a real regression instead of removing the race.
The CI comment now records both Windows failure classes with their evidence,
so the next person can tell what this flag is for.
- docs/plans/2026-09-11-file-icons-and-tab-glyphs.md: the design record —
what the two stacked PRs did, the measured upstream facts that made their
colored implementation redundant (rc.2's `FileTypeIcon`/`CodeFileIcon` with
the host's own palette, the classifier never returning a folder, the native
tab definition having no icon field while its title slot IS the chip), the
three merge conflicts and how each was resolved, what was deleted, the
catch-all semantics change, and the verification evidence.
- docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md: cross-link it from the
change table.
- docs/external-plugin-guide.md: the file-icon fallback chain now ends at the
host's artwork, with the catch-all caveat spelled out; §12 loses its "one
exemption" paragraph entirely — the plugin draws no color of its own any
more (file icons are host pixels, tab glyphs ride tokens).
- AGENTS.md §5: replaces the icon-theme exemption with the two new rules
(file-icon chain + catch-all hazard, and where the colored tab glyphs live
plus the fact that the native chip glyph is drawn by the plugin inside the
host's title slot).
- README.md / README_EN.md: the v0.19.1 entry gains the icon section
(#611 / #531 / #594) with the dataset deletion and the new public API.
ci-windows is green twice on 5451f5c — the PR-triggered run 34561189320 and a
follow-up workflow_dispatch run 34561457067, both 126 files / 1318 passed /
3 skipped with zero `Unhandled Errors` and zero `Worker exited unexpectedly`
(the window that motivated this work saw two of the latter). plugin-mount is
green twice as well: `added 521 packages in 24s` with no ERESOLVE lines
against 3062 in the historical OOM run, mount smoke 7 passed, aggregate lane
passed.
Also records the falsification this PR went through — the first cut still
failed on real CI in two places (the third 5000 ms default victim,
tests/git.spec.ts:85 at 9607 ms, and `--legacy-peer-deps` breaking the CLI
install with ERR_MODULE_NOT_FOUND) — and states plainly that two green runs
do not prove the worker-death root cause, only that it stopped reproducing
once concurrency was bounded and the timeout budgets were corrected.
The first run of this PR against real Windows and real npm found two things
the local macOS pass could not:
1. ci-windows lost a THIRD file to vitest's 5000 ms default —
`tests/git.spec.ts:85` ("caps status entries at the truncation limit")
took 9607 ms building a pathological untracked set with real git calls.
Three different files (git / powershell / agent-pty), one root cause, so
per-file timeouts were whack-a-mole: vitest.config.ts now sets a global
`testTimeout: 15_000`. The two heaviest suites keep their own 30 s budgets
and a genuinely hung case still fails.
2. `--legacy-peer-deps` made the mount lane's CLI install broken instead of
robust: it skips exactly the peers a global install has to supply, and
`@deepseek-ai/cordis-plugin-group` — required at boot by
`@deepseek-ai/dsh-app-boot` — is a peer, not a dependency, so the CLI died
with ERR_MODULE_NOT_FOUND (`Cannot find package
'@deepseek-ai/cordis-plugin-group'`) before the smoke could start. The
flag is removed; the pin to a fully-published rc.2 (no ETARGET) plus the
4 GB heap (no resolver OOM) is the whole fix.
Verified locally: a plain `npm install -g @deepseek-ai/dsh@0.1.5-rc.2` into a
scratch prefix (with NODE_OPTIONS=--max-old-space-size=4096) resolves the peer
(`dsh/node_modules/@deepseek-ai/cordis-plugin-group` present), that CLI reports
0.1.5-rc.2, and `DSH_CMD` pointed at it runs the mount lane green — 7 passed.
`pnpm test` stays green with the new timeout: 126 files / 1312 passed / 9 skipped.
Docs (plan §C, AGENTS.md §2, both READMEs' v0.19.1 entries) record the rejected
middle step and why, so nobody re-adds it.
