• Migrate all workspace Vitest dependencies to 5.0.4 and update Workers scaffolding templates to v5.
• Replace the published v4-only Workers pool with @cloudflare/vitest-plugin@1.4.3 for four shared packages, preserving the dependency-cycle boundary. Templates require plugin 1.4.3 or newer, so all consumers can use filesystem module caching.
• Update sequential test APIs, custom matcher declarations, and the workflow RPC test for v5; retain compatible public v4/v5 peer ranges.
• Register credentialed Wrangler dev suites even when skipped, using full names matching their snapshots.
• Use native filesystem-cache and V8 coverage support from plugin 1.4.3; remove all temporary cache opt-outs.
• Validation: pnpm check; 772 shared-package tests and 120 plugin tests pass. The focused local Wrangler dev E2E tests pass in CI mode without credentials.

  • Tests included/updated
  • Automated tests not possible - manual testing has been completed as follows:
  • Additional testing not necessary because:
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: this updates test tooling and generated dependency versions without changing the Workers configuration API.

Looks like it needs a rebase and I propose that you split the changeset. Otherwise LGTM

[clanky-the-clanker]

✅ Approved — No problems found. The Vitest 5 migration is consistent across manifests, test APIs, snapshot names, templates and changesets, and it changes no production code at runtime.

_{The decision is advisory: this comment never approves, blocks or requests changes on the pull request.}

---

✅ All checks passed

🚀 Release: ✅ LGTM

Risk: low. Patch changesets cover the wider peer ranges and the template updates.

---

🔒 Security: ✅ LGTM

This pull request only changes test tooling and dependency versions. It has no security impact.

---

📖 AGENTS.md: ✅ LGTM

The update to packages/miniflare/AGENTS.md matches the new API.

---

📋 Code Quality: ✅ LGTM

Checked the switch from sequential to { concurrent: false }, the restructured Wrangler dev E2E suite (its names still match the snapshot keys), the matcher type augmentation, removal of the old catalog and pool references, and the workflow RPC test's prototype spy. Everything is consistent.

---

⚡ Performance: ✅ LGTM

The change does not touch any runtime code path.

---

📝 Documentation: ✅ LGTM

The changesets and the package AGENTS.md update match the change.
