jeda 57e8193f7b feat(bd-2kf): Add comprehensive test coverage for parser and store

- Add 36 parser tests covering:
  - parseLogLine with valid/invalid inputs
  - parseLogLines for multi-line parsing
  - formatEvent with all options
  - Edge cases: malformed JSON, missing fields, colorization

- Add 35 store tests covering:
  - InMemoryEventStore add/query operations
  - Worker status tracking (active/idle/error)
  - Event filtering by worker, level, bead, timestamp
  - maxEvents limit and LRU trimming
  - getStore/resetStore singleton management

- Close phase beads (bd-2pa, bd-n8l, bd-2nu) as infrastructure complete
- Close test beads (bd-5eh, bd-2en) with comprehensive coverage
- Total: 91 tests passing across parser, store, and tailer

FABRIC Implementation Roadmap

Overview

This roadmap outlines the implementation plan for FABRIC (Flow Analysis & Bead Reporting Interface Console). Features are organized into phases with clear priorities.

Current Status

Completed:

Phase 1: Core Infrastructure
- types.ts - Core type definitions
- parser.ts - Log line parsing
- store.ts - In-memory event store
- tailer.ts - Log file tailing
- cli.ts - Command-line interface
- index.ts - Main exports
- Basic test coverage
Phase 2: TUI Implementation ✅ COMPLETE
- P0: Setup blessed TUI framework
- P1: Worker Grid Panel
- P1: Activity Stream Panel
- P2: Worker Detail View
- P2: Keyboard Navigation
- P3: Stuck Detection (src/tui/utils/stuckDetection.ts)
- P3: Inline Diff View (src/tui/components/DiffView.ts)
- P4: Command Palette
- P4: Cost Tracking (src/tui/utils/costTracking.ts)

In Progress:

Phase 3: Web Dashboard

Phase 2: TUI Implementation

Priority Order

Priority	Feature	Description	Effort
P0	Setup blessed	Add blessed library for TUI framework	Low
P1	Worker Grid Panel	Display all active workers with status	Medium
P1	Activity Stream Panel	Scrolling log output with filtering	Medium
P2	Worker Detail View	Detailed view for single worker	Medium
P2	Keyboard Navigation	j/k scroll, / search, Tab switch, q quit	Low
P3	Stuck Detection	Detect workers spinning their wheels	Medium
P3	Inline Diff View	Show diffs in Edit tool calls	Medium
P4	Command Palette	Ctrl+K universal search	Medium
P4	Cost Tracking	Token usage and budget alerts	Medium

Implementation Approach

Use blessed for terminal UI
Create modular components in src/tui/ directory
Each feature gets its own file
Shared state management via store

Phase 3: Web Dashboard

After Phase 2 is complete:

Priority	Feature	Description
P1	HTTP Server	Express/Fastify server
P1	WebSocket	Real-time updates
P1	React Frontend	Browser UI components
P2	Timeline Viz	Worker activity timeline

Intelligence Features (Phase 4+)

These can be added incrementally after core UI is working:

Cross-Reference Hyperlinking
Worker Collision Detection
Session Replay
Smart Error Grouping
Task Dependency DAG
File Heatmap
Recovery Playbook

Quick Start for Workers

Start with P0: Setup blessed
Then P1: Worker Grid Panel
Then P1: Activity Stream Panel
Continue through priority order

Testing Strategy

Unit tests for each component
Integration tests for TUI workflows
Visual testing with sample log files
