Module binary_identity 

The binary this process started from, so a long-running MCP server can say when an install replaced it on disk. An MCP server keeps running the engine it started with: on 25.10. every agent session still ran a two-day-old engine after three installs, and fixes reached nobody until a reconnect.

Functions

record_start

Record the executable as it is now; call once, early in main.

replaced_note

The note for an agent when the binary on disk is no longer the one this process started from; None while they match (or nothing was recorded).
