The mint leaves the control plane's old-bus secret alone

The control plane is a module too, and its broker secret is the old bus's credential it is still using while the mint runs. Writing the new bus's blob there cut the mesh off from its own old bus mid-move. Its new-bus credential is the controller principal's bus secret; the module principal is skipped.

jschoubben	f8a9c3d6bc	The control plane mounts the bus secret it reads MESH_BUS_NATS_FILE named /run/secrets/bus and nothing put a file there: the manifest binds each secret explicitly, and the switch added the secret and the variable but not the bind. Found live — the control plane came up on the new bus and could not read its own credential.	2026-09-28 01:03:18 +02:00
