v2.0.0

What's New

Cross-Mission Memory Store (#94)

• Persistent pattern library (.nelson/memory/patterns.json): accumulates adopt/avoid patterns from every mission
• Standing order stats (.nelson/memory/standing-order-stats.json): tracks violation frequency and correlations across missions
• Pattern capture: stand-down now accepts --adopt and --avoid flags to record reusable patterns
• Intelligence brief (brief command): pre-mission command that surfaces relevant patterns, win rate, standing order hot spots, and context-matched precedents
• Cross-mission analytics (analytics command): focused metric queries (success-rate, standing-orders, efficiency) with text and JSON output
• Index sync: running index backfills the memory store for missions completed before this feature existed

Modular Architecture

• Split monolithic nelson-data.py (2500+ lines) into 5 focused modules:
  • nelson-data.py — thin CLI entry point (340 lines)
  • nelson_data_utils.py — shared I/O, validation, constants
  • nelson_data_memory.py — cross-mission memory store
  • nelson_data_lifecycle.py — mission lifecycle commands
  • nelson_data_fleet.py — fleet intelligence and analytics
• Test suite split into 3 files with shared conftest.py

Bug Fixes

• Replaced bare open()+try/finally lock pattern with _file_lock() context manager across all lock sites
• Fixed mid-file import and replaced time.sleep with deterministic mission IDs in tests
• Fixed duplicate record-building code in cmd_index() that ran outside the file lock

Test Coverage

• 234 total tests (182 scripts + 52 hooks), all passing
• 21 new tests for memory store, brief, analytics, and index sync
