Best possible solution:

Use one directory link helper for both the probe and all gated symlink setup, then add redacted Windows terminal proof for the touched workshop test.

Do we have a high-confidence way to reproduce the issue?

Yes from source inspection: the new probe uses a different Windows link type than the test bodies it gates. I did not run a Windows host reproduction in this read-only pass.

Is this the best way to solve the issue?

No. The maintainable fix is to align the capability probe with the exact link type used by the gated tests, or to update the test setup to use the cross-platform link type consistently.

Full review comments:

• [P2] Use the probed link type in the tests — src/skills/workshop/service.test.ts:7
  The new gate probes Windows by creating a junction, but the tests it enables still call fs.symlink(..., "dir"). Node treats those as distinct Windows link types, so a host that can create junctions but cannot create directory symlinks will pass the probe and then fail during test setup; use the same helper in the test bodies or probe dir instead.

What I checked:

• PR head mismatch: The new probe uses process.platform === "win32" ? "junction" : "dir", but the gated test bodies still create links with fs.symlink(..., "dir"). (src/skills/workshop/service.test.ts:7, 9ae1ee99956c)
• Current main behavior: Current main skips the four workshop symlink tests on every Windows host, and those bodies create directory links with the dir type. (src/skills/workshop/service.test.ts:139, 9c95abd49d45)
• Sibling pattern: A nearby cross-platform directory symlink test helper uses the same link type for both the capability probe and each test-body symlink creation. (src/infra/install-safe-path.test.ts:17, 9c95abd49d45)
• Node symlink contract: Node documents Windows symlink types as distinct dir, file, and junction choices, with junction-specific behavior; probing one type does not prove the other test setup type works. (nodejs.org)
• History provenance: The workshop symlink tests and related write-path implementation appear to have entered main through merge commit 9d800b7 for fix(scripts): route i18n formatter through pnpm runner #95534. (src/skills/workshop/service.test.ts:139, 9d800b71c060)
• Related search: GitHub search did not find a merged or open canonical item for this exact workshop symlink Windows test-portability change beyond this PR.

• 🦀 challenger crab: rare, exceptional readiness with strong proof, clean implementation, and convincing validation.
• 🦞 diamond lobster: very strong readiness with only minor maintainer review expected.
• 🐚 platinum hermit: good normal PR, likely mergeable with ordinary maintainer review.
• 🦐 gold shrimp: useful signal, but proof or patch confidence is still limited.
• 🦪 silver shellfish: thin signal; proof, validation, or implementation needs work.
• 🧂 unranked krab: not merge-ready because proof is missing/unusable or there are serious correctness or safety concerns.
• 🌊 off-meta tidepool: rating does not apply to this item.

Shiny media proof means a screenshot, video, or linked artifact directly shows the changed behavior. Runtime, network, CSP, and security claims still need visible diagnostics.
