[Unreleased] - 2026-08-19

🐛 Bug Fixes

• Multi-Floor Script Syntax (run_all_coops.sh):
  • Resolved fatal syntax error: unexpected end of file caused by missing done in floor configuration discovery loop.
  • Expanded config discovery pattern from K*-L*.yaml to *.yaml to support custom named coops (e.g. kandang-atas.yaml).
• Excel Report Empty Result Crash (export_excel_report.py):
  • Added empty DataFrame pre-check to prevent IndexError when exporting reports for dates with no batch runs or newly initialized databases.
• Multi-Threaded SQLite Concurrency (dashboard.py):
  • Replaced global single sqlite3 connection with thread-local connections (threading.local()) to prevent cursor collision and race conditions across concurrent HTTP worker threads.
  • Enabled PRAGMA busy_timeout = 5000 and PRAGMA journal_mode = WAL to avoid database lock conflicts during batch processing writes.
• Editable Package Installation:
  • Configured pip install -e . in environment setup to resolve chicken_counter imports and enable automatic unit test discovery without manual PYTHONPATH prefixes.

⚡ Performance & Optimization

• Disk Traversal Caching in Live Dashboard (dashboard.py):
  • Replaced repetitive Path.rglob() scans on every /api/mortality/* endpoint with a thread-safe 15-second in-memory TTL cache (_MORTALITY_CACHE_TTL = 15.0s).
  • Added O(1) memory index lookup for serving annotated images (/api/mortality/image/<filename>), eliminating full filesystem traversals across 30GB+ video datasets.

📁 Configuration & Directory Structure

• Floor Configuration & Skeleton Paths:
  • Created configs/floor_config/kandang-atas.yaml extending cycle7_batch_optimized.yaml.
  • Initialized missing directory skeletons for coops K1-L1 through K5-L2 under ../VIDEOS/cycle7/.
• Documentation:
  • Updated README.md and RUN.md with editable install steps and updated project layout.
