Suriyakumarvijayanayagam 4c750cb2ac Opening a shop is an API call; the broker learns of it in the same request ...

The last step of onboarding that needed a shell: provision site printed
a broker password and a person typed it into Mosquitto's passwd file on
the host - mounted read-only in the container, so the first attempt
failed silently and the password was re-rolled. No tenant could open a
second branch without us.

The server now drives Mosquitto's dynamic-security plugin over its own
broker login: POST /api/sites (owner) writes the row and the sealed
password, registers the login and a per-site role with literal topics
(the 2.0 plugin does not substitute %u - measured), and removes the row
again if the broker refuses, so a shop cannot exist in the database and
not on the broker. provision site goes through the same path. The
head-office Shops screen gets 'Open a new shop'.

broker-init converts the existing passwd file into the plugin's store
with every hash intact - PBKDF2-SHA512 both sides - so the cutover
re-claims no shop PC. Rehearsed locally: old logins keep working,
isolation holds, the health probe works, and a PC claiming a shop opened
through the API connects as that shop. run-local.sh now brings the
broker up the same way.
