Plan 3: Error Detection & Phase Transitions

[iamladi]

Overview

Port error detection logic (hash-based stuck detection) and phase transition management with 80%+ test coverage.

Research Source

• research/research-workflows-tdd-migration-deep.md
• Migration Roadmap Phase 2 (Tasks 6-8)
• Section 4: Complete Migration Example

Tasks

• Create src/core/error-detector.ts with hashError and detectStuck functions
• Create tests/unit/core/error-detector.test.ts
• Create src/core/phase-manager.ts with Phase type and transitions
• Create tests/unit/core/phase-manager.test.ts
• Update vitest.config.ts with 80% coverage thresholds

Complexity

5/10

Acceptance Criteria

• detectStuck returns isStuck: true after 3 identical errors
• detectStuck resets counter when error changes
• Phase transitions follow valid state machine
• Coverage at 80%+ for core/ directory

Dependencies

• Depends on: Plan 2: Testing Infrastructure & Core Logic #5
