Validated in a combined 10-PR batch worktree off release/v3.8.51 tip.
- Focused test: tests/unit/tailscale-validation.test.ts — 2/2 pass plus 13/13 related Tailscale tests
- typecheck:core, file-size, changelog-integrity, complexity, cognitive-complexity gates — all OK
- Full-repo lint: 503 pre-existing problems confirmed identical on the pure release/v3.8.51 tip — unrelated to this diff
⚠️ base-red inherited: #11449
Thanks for rejecting out-of-range Tailscale ports and escaping apostrophes before they reach the Windows MSI installer PowerShell command.
