A till signs in with a mobile number and a PIN, but createposuser still
accepted an account without a number. Such an account cannot reach the
sign-in screen at all, and the failure surfaces at a counter in front of
a queue rather than at the point of creation. Enforced in CreatePosUser,
so both doors are covered: POST /pos/users from the terminal and
createposuser from the console share that path.
Two checks, not one. normalisePosPhone answers ("", nil) rather than an
error for a value holding no digits, so "abc" would have passed an
emptiness check, then been written as a blank and skipped the uniqueness
check below it — which is the hole this closes.
Scope is new accounts only. The column stays nullable and UpdatePosUser
still reads an empty contactno as "leave alone", so the accounts that
predate the number keep working through the backfill and cannot have
theirs cleared. The PIN stays optional at creation.
Also in this change:
- docs: correct both phone-login handovers, which claimed creation
already required a number. The sequencing note in the PIN handover
said step 2 was a backfill that could never be finished; it now is
one, and POS_LOGIN.md says which half of the pair creation enforces.
- docs: remove credentials from the examples. POS_PHONE_LOGIN_HANDOVER
carried a real-looking back-office pair and a generated till password,
and POS_LOGIN.md a second one.
- posController.Staff: the comment justified scoping by token because
"the answer carries PINs". It has not since the PIN left the wire. The
scoping is still right for a different reason, which the comment now
gives.
- scratch/posstaffsetup: takes both mobile numbers as arguments and
refuses to run without them. Generating stand-ins would have produced
exactly what this change prevents. Validated before the database is
opened, in plan mode too, so a dry run cannot print a plan that apply
would reject halfway through and leave half a shop set up.
