Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

On solo plans your memories are yours alone. On Team plans you choose, per project, which memories teammates can recall, and every shared memory is attributed to who saved it."
