REAL T3 SERVER CAPTURE — BEFORE
Commit: b3fdf2b10fb92e5dbc71a83381c602a8a464bbca
Surface: Node T3 server, loopback HTTP, fresh isolated database.
Both instances enabled; common homePath; second instance has shadowHomePath.
Probe boundary: recorder binary logs CODEX_HOME/arguments and deliberately exits 1.
No successful authentication is claimed.
Queue family: synthetic regular files (not live databases), one distinct marker per member and home.
