Key features

• Write safetysingle writer lease lock + recoverable transaction, multi-file changes are atomic, raw only appends but does not overwrite
• Important boundariesThis repository only contains "mechanisms" and does not contain any personal data.
• What to doWhen a new session starts, compress the "memory that needs to be known most at the moment" into a ≤14KB hot packet and inject it at once, so that the Agent can start working with the context without reading the entire database.
• Chinese recallChinese bigram BM25 + exact/title/path matching + metadata rearrangement, the whole trace can be explained
