The role split was right; only its source was wrong. Signing in matched what
was typed against two constants compiled into the app — admin@nearle.in and
cashier@nearle.in — so which shell a person got was a property of the *build*.
A shop could not add a third person, revoke either of the two it had, or stop
anyone with the APK reading both passwords out of it.
TerminalLogin survives unchanged in shape, because the shape was the good part:
one flag the shell reads, a session that decides it, and a cashier sign-out that
takes the catalogue with it while a supervisor's leaves it behind. Every
consumer — visibleModulesProvider, resolvedModuleProvider, the sidebar, the page
header, the sign-out dialog — is untouched. What changed is that the enum is now
only constructible from a session the back office signed, so there is no path
left where the terminal grants itself a permission the server did not send.
It reads `can_manage_staff` rather than the role name or id. app_roles holds six
rows for four distinct roles, a great many accounts carry a roleid that is not
in the table at all, and the name comes back blank for most of them. Matching on
either would mean shipping a copy of the role table in the app and keeping the
two in step for ever. One boolean, decided server-side, cannot drift. It
defaults to false, which matters on the restore path: a session saved by a build
that predates the field comes back as a cashier, never silently as an admin.
This also restores the sign-in layer itself — pos_auth_api, pos_session,
session_store, the staff import and the bearer token — which an earlier commit
removed wholesale from a stale checkout. Its parent was the commit that added
them, so the deletion was a bad merge rather than a decision; the terminal has
been running on the two constants since.
The login screen loses its role tabs and its credential prefill. You do not
choose what you are on the way in.
The opener is now matched on the back office user id rather than on the first
account with a matching role, so the first bill of a shift is attributed to
whoever actually signed in.
Tests: the smoke suite pinned only the supervisor shell, and it was passing for
the wrong reason — the fake session omitted can_manage_staff, and the sidebar it
asserted on was there because the role was hardcoded. Both halves are pinned now
and the fake is parameterised. widget_test.dart was the stock Flutter counter
template, restored by the same bad merge, testing a MyApp that has never existed
in this repo.
292 tests pass; analyzer reports no errors and no warnings.

Wires the last two dead buttons in Settings and closes the loop on the
credential work: hashed PINs are only worth having if a shop can actually
change them.
Users & roles (Manage)
- Add, rename, re-role and remove staff. Admin-only at the door, because
anyone who can edit staff can make themselves an admin.
- PIN and confirmation are both required and must match. There is no email to
reset a PIN with, so a typo nobody can verify locks the account out until an
admin intervenes.
- Editing someone leaves their PIN alone unless a new one is typed. An admin
setting another person's PIN counts as a reset and re-arms must-change.
- Removal is a deactivation with a confirmation that explains why: bills
already rung keep the cashier's name, so shift reports stay correct.
- Anyone still on a shipped PIN is flagged in the list and in Settings.
Store details (Edit)
- Name, address, GSTIN and phone now editable and persisted. GSTIN is format
and state-code validated; it prints on every invoice as a legal requirement,
so a typo is a compliance problem across hundreds of bills.
- Admin-only: changing the GSTIN changes what every future invoice claims
about who collected the tax.
Forced PIN change
- Shown once after sign-in while must-change is set, and not dismissable. The
seeded PINs are in the source of the build, so a terminal still running one
is effectively unprotected.
Fixed while testing: the role dropdown laid its items out at natural width and
"Manager — Sales, inventory and reports" overflowed the dialog by 222px. Now
isExpanded with the description spelled out below, where it is readable.
Tests: 160 -> 168. Covers both role guards, the mismatched and too-short PIN
paths, the default-PIN flag, and GSTIN and seller-name validation.
