Research direction
Start at windows/birdlock/core/aircraft.py:50-66: read AircraftPartsModel._load() and the verify_model() call it makes, then follow AircraftAnalyzer.start_analysis() and close() to confirm each analysis rebuilds the model object and discards the cached session. Add a process-level cache keyed by (path, st_size, st_mtime_ns) around the verification result so the first load still hashes fully. Done when a second consecutive aircraft analysis skips the ~203 MB hash while a changed AircraftParts.onnx still triggers re-verification; time two runs on Windows to confirm the startup gain, since the report was derived from an audit rather than a live repro.
Written by the indexing model from the issue text.
Description
位置：windows/birdlock/core/aircraft.py:50-66
现象：AircraftPartsModel._load() 调用 verify_model() 完整读取并哈希模型（AircraftParts.onnx 约 203 MB）；AircraftAnalyzer 每次 start_analysis() 新建实例、结束 close() 释放 session，下一次分析又重新哈希。
复现：连续两次进入飞机分析，观察启动耗时。
建议：进程内按 (path, st_size, st_mtime_ns) 缓存校验结果（首次仍完整哈希）。
