Epic 01.4: Scoring & snapshots done

[opencode-agent]

I've implemented the scoring and type snapshots functionality for Epic 01.4. Here's what was created:

New Files:

1. constants/scoring-contract.ts - Type definitions for:

   • AxisScores, AxisStrength, TypeSnapshot, ScoreAccumulator
   • Complete type system for storing and reconstructing personality snapshots

2. lib/scoring.ts - Core scoring utilities:

   • calculateAxisScores() - Each answer contributes to one side of one axis
   • calculateAxisStrength() - Normalized strength from -1.0 to +1.0
   • computePersonalityType() - Deterministic type calculation
   • createTypeSnapshot() - Creates storable/reconstructible snapshots
   • createScoreAccumulator() - Real-time incremental scoring
   • Helper functions for snapshot validation and comparison

3. lib/scoring.test.ts - Comprehensive test suite

4. lib/index.ts - Module exports

All acceptance criteria satisfied:

• ✓ Each answer contributes to exactly one side of exactly one axis
• ✓ Same answer history always produces the same Current Type
• ✓ System derives axis strength from gap between poles (-1.0 to +1.0)
• ✓ Sessions produce storable/reconstructible type snapshots
• ✓ Outputs support both per-day history and overall current type views

Closes #19

@codex merge main and resolve merge conflicts. Fix ci failures

[chatgpt-codex-connector]

Summary

• I fixed the CI/typecheck failure by updating the createScoreAccumulator test to assert AxisStrength fields (rawDifference, strength, dominantPoleId) returned by buildStrengths() instead of non-existent poleA/poleB fields. This aligns the test with the scoring contract and unblocks TypeScript CI.
• I committed the change on the current branch with commit 5e15137 (Fix scoring accumulator test for AxisStrength shape).
• I also attempted to merge main, but this checkout does not currently have a local main branch (merge: main - not something we can merge), so no merge-conflict resolution was possible in this environment.

Testing

• ✅ pnpm lint
• ✅ pnpm typecheck
• ✅ pnpm test:ci
• ⚠️ git merge main (warning: no local main branch exists in this environment, so merge could not be performed)
