Summary

• Treat whitespace-only auth-key expiry as unset so Tailscale applies its default lifetime.
• Share DNS and tailnet-settings response mappings, output schemas, and response types.

Type of Change

• Bug fix and cleanup

Testing

• VITEST_MAX_WORKERS=2 bun run test (full root gate)
• 48 focused parser and workflow-builder cases; the whitespace-expiry wire regression fails before its fix and when the normalization guard is removed
• bun run lint, bun run type-check, bun run check:test-types, and all 61 check:audits checks
• Block registry check against origin/staging; regenerated metadata and integration documentation
• Cross-checked auth-key expiry semantics against the official Tailscale OpenAPI specification

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Tests added/updated and passing (new tests pass the test-audit authoring gate)
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)
