Fix tS errors that prevent deployment

[AutumnsGrove]

• Add explicit Feature type with optional properties (internal, major, dream)
• Fix roadmap features type inference by adding Record type to phases
• Use untrack() in unsubscribe page to properly capture initial email value
• Resolves svelte-check errors preventing deployment

This fixes the CI/CD build failures where svelte-check was reporting 2 errors and 1 warning in 2 files.

PR Review: TypeScript Error Fixes

Summary

This PR successfully resolves TypeScript compilation errors that were blocking deployment. The changes are well-structured and demonstrate proper understanding of TypeScript type inference and Svelte 5 reactivity patterns.

---

✅ Code Quality

Roadmap Page (packages/landing/src/routes/roadmap/+page.svelte)

The addition of explicit type definitions is excellent:

1. Feature Type Definition (lines 74-82)

   • Well-documented with clear explanations of each optional property
   • Properly structured with optional properties using ? syntax
   • Good use of JSDoc-style comments explaining the purpose

2. Phases Record Type (lines 93-99)

   • Correctly uses Record<PhaseKey, {...}> pattern for type-safe object indexing
   • Ensures all phase properties are properly typed
   • This prevents the TypeScript inference errors that were occurring before

Unsubscribe Page (packages/landing/src/routes/unsubscribe/+page.svelte)

The use of untrack() is appropriate here:

1. Proper Import (line 2)

   • Correctly imports from 'svelte'

2. Correct Usage (line 13)

   • untrack(() => data.email || '') properly captures the initial value without creating reactive dependencies
   • The comment explains the intention clearly
   • This is the right pattern for capturing initial values in Svelte 5 runes

---

🔒 Security Considerations

No security concerns identified. The changes are purely type-related and don't introduce any new attack vectors.

• Email input remains properly validated (type="email", required attribute)
• No changes to data handling or sanitization logic

---

⚡ Performance Considerations

Positive performance impact:

The untrack() usage in the unsubscribe page is actually a performance improvement:

• Prevents unnecessary reactive subscriptions to data.email
• The email field should be independently editable, not tracking the original data source
• This is the correct Svelte 5 pattern for "capture initial value, then make it independent"

---

🐛 Potential Issues

Minor suggestion: Consider adding a type annotation to the email state variable for extra clarity:

let email = $state<string>(untrack(() => data.email || ''));

This is optional but makes the intent more explicit.

---

🧪 Test Coverage

The PR description mentions this fixes CI/CD build failures. Based on the workflow configuration:

• ✅ Type checking via pnpm check (svelte-check) - This PR directly addresses this
• ⚠️ Recommendation: Consider adding unit tests for:
  • The Feature type interface (could use a type test)
  • The unsubscribe email initialization behavior

Example type test (optional):

// In a test file
import { describe, it, expectTypeOf } from 'vitest';
import type { Feature } from './+page.svelte'; // if exported

describe('Feature type', () => {
  it('should allow all optional properties', () => {
    const feature: Feature = {
      name: 'Test',
      description: 'Test desc',
      done: false
    };
    expectTypeOf(feature).toMatchTypeOf<Feature>();
  });
});

📚 Best Practices Alignment

Excellent adherence to Grove's coding standards:

1. ✅ Engine-First Pattern - Uses @autumnsgrove/groveengine imports correctly
2. ✅ Code Comments - Clear, helpful comments explaining the "why"
3. ✅ TypeScript Strictness - Proper type safety without any or type assertions
4. ✅ Svelte 5 Patterns - Correct use of runes and modern Svelte idioms
5. ✅ Minimal Changes - Only fixes what needs fixing (no scope creep)

---

📋 Documentation Checklist

Based on the PR template, this appears to be correctly marked as:

• No docs needed — These are internal type fixes with no user-facing changes

---

🎯 Verdict

✅ Approved - Ready to Merge

This is a clean, focused PR that:

• Solves the stated problem (TypeScript errors blocking deployment)
• Uses appropriate TypeScript and Svelte 5 patterns
• Includes helpful comments
• Introduces no regressions or security concerns
• Follows Grove's coding standards

The only suggestion is the optional type annotation mentioned above, but that's not blocking.

Great work on the type safety improvements! 🌲
