From b1e31363504ee237fb7b57f4308c60f237e6f92b Mon Sep 17 00:00:00 2001 From: Test Date: Sun, 23 Aug 2026 16:49:25 -0700 Subject: [PATCH] feat(T1.4): implement board state validation and auto-healing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add internal/board package with validation and state tracking - Implement BoardValidator for comprehensive board file validation - Detect missing headers, malformed tables, invalid task IDs - Validate status fields ([x] or [ ]) - Parse task information from valid boards - Implement StateTracker for actual task state management - Track task progression (pending → in_progress → completed/failed) - Support task metrics attachment and analytics - Implement divergence detection: compare board vs actual states - Implement auto-healing: fix state mismatches between board and reality - RepairBoard() fixes structural corruption issues - HealDivergence() updates board to match actual states - Support both JSON persistence and in-memory operation Validation Features: - Detailed error reporting with line numbers and context - Warning system for suspicious but valid boards - Task ID format validation (T#.# pattern) - Status value normalization ([X] → [x]) - Table structure verification State Management: - Persistent JSON storage of task states - Completion/failure timestamps - Custom metrics per task - Thread-safe RWMutex synchronization - Stats and filtering operations Healing Features: - Non-destructive repairs (report changes) - Board integrity preservation - Divergence detection with timestamps - Batch update capability - Change tracking for audit trail Test Coverage: - 13 validator tests (structure, validation, repair, parsing) - 16 state tracker tests (tracking, persistence, analytics) - 29 total board tests, all passing - Edge cases: empty boards, invalid formats, multiple tasks - Multi-state transitions and metrics Key Design: - Separation of concerns: Validator (format) vs Tracker (state) - JSON persistence (human-readable, debuggable) - Thread-safe concurrent state updates - Detailed error messages with context - Non-breaking repairs (safe by default)
