Cross-plugin FK blocker ADR-013 cited is already resolved: the FKs into
machines were held only by dead legacy tables (machinerelationships,
printerdata, installedapps, communications.machineid) that existing
migrations 7a01/7c01 already drop. No live plugin table hard-FKs another
plugin. Schema-lean is unblocked.
Enabling change: create_plugin_tables now skips already-existing tables
(idempotent) so a plugin anchor can create its tables on a fresh lean
install and no-op on a database that has them from the pre-cutover
baseline. The load-bearing baseline lift is staged as ADR-014 Phase 2.
Loader: bool() on pymysql bit(1) bytes is always true - isinstallable
and isshopfloor imported as 1 for every row; route through _truthy_bit.
The employee source DB is now optional (shopdb-only imports).
Frontend: under a subpath mount the 401 interceptor stored the browser
path (mount base included) as the login redirect and the router applied
its base again (/ops/ops). New stripBase() keeps redirects base-free.
tools/export-github.sh automates the publication flow: prune + scrub +
commit into ~/projects/shopdb-flask-pub and emit a transfer bundle.
