cbdfcbabb7 One badge vocabulary, and images a browser can actually load
Two operator-visible defects and three doc corrections, closing the tail of the
2026-09-03 run.

THE BADGE. The two kiosks read the same physical badges and disagreed. The
parts kiosk understood both shapes a scanner emits - the bare SSO and the PayNo
wrapper 0<digits>BZ - while the USB kiosk compared the raw string to an SSO, so
the wrapper resolved to nobody. An operator whose keyboard-wedge scanner emits
it could take a 3D-printed part and could not check out a drive, with the same
badge, at two cabinets a few metres apart.

The shape now lives in shopdb/utils/badges.py on the contract surface, because
a plugin may not import another plugin and because a badge is a property of the
site rather than of a cabinet. Both kiosks use it, and both store the DIGITS
rather than the string that arrived: one row per spelling makes a custody
history that cannot be joined to itself.

That closed a subtler hole in the same place. str.isdigit() is true for
Arabic-Indic and other decimal forms, and int() parses them, so a badge written
in those characters was accepted, matched a REAL employee, and was then stored
as an SSO string nothing else matches. ASCII digits only. An empty scan and an
unreadable one now get different answers, because they are different problems
for the person at the cabinet.

THE IMAGES. /api/applications/image/<filename> and /api/models/image/<filename>
required a permission, and a browser fetching <img src="..."> sends no
Authorization header - so the gate did not protect the file, it guaranteed the
picture never appeared. Both are ungated now, like the four sibling image routes
(branding logo, map blueprint, employee photo, part picture), and registered in
PUBLIC_ENDPOINTS with that reasoning.

/api/printers/lookup?fqdn= never matched anything: both arguments were compared
against Communication.ipaddress, so a hostname lookup 404d on printers whose
hostname was on the record. An FQDN now matches the hostname, with a fallback to
the short name.

The slide manager gained the per-slide hold time. The PATCH route and the feed
have always carried `seconds`; nothing called it, so the one documented
per-slide control was curl-only.

Docs: API-REFERENCE listed the employee lookups and the whole notifications
surface as unauthenticated when they answer 401, and called both kiosks
"deliberately open" when they are off by default and refuse anything without the
site's device token. The installer download says applications.download, which is
what the code requires. api-inventory.json said printers/lookup was
jwt-optional.

Fourteen tests. The badge rule verified by planting the old per-kiosk behaviour:
three fail, one in each kiosk.

aa8028f96e Let the row refuse the write both kiosks were deciding in Python
Wave 1 of the remediation plan for the 2026-09-03 feature test run. Two kiosks,
one shape of defect, one critical consequence.

Both kiosks read the state, decided in Python, and then wrote. Nothing stops two
requests interleaving between the read and the write, so both see the same
pre-state and both proceed. Reproduced on MySQL 5.6 over HTTP, five concurrent
takes of 5 from a bin holding 5: all five were accepted and quantityonhand
landed on -20, because each request wrote its own arithmetic. The ledger had
recorded every one of them, so the cached quantity and the ledger disagreed
permanently, which is the number the shop floor actually reads. The USB kiosk
had the same shape: concurrent scans of one drive all succeeded and inserted
several open custody rows, so one drive was recorded out to two people and the
documented 409 never fired.

The comparison now lives in the WHERE clause, where the database settles it at
write time. printedparts._move_quantity issues
UPDATE ... WHERE quantityonhand >= :n and treats rowcount 0 as the refusal,
raising InsufficientStock, which take and adjust turn back into the message they
already gave - carrying the quantity the database holds now, not the stale one
the request read. The low-stock alert derives its before-value from what the
write produced for the same reason. Both USB paths claim the device with
ischeckedout (self-hosted) or status (external cmmc_usb) in the WHERE clause;
the external one claims BEFORE writing the log line, so a refused claim leaves
nothing to undo. Check-in is guarded the same way.

After the fix, the same five concurrent takes: one accepted, four refused,
quantityonhand 0 and the ledger sum 0.

Check-in also closes EVERY open row for the device rather than the newest.
One device can only be out once, so a second open row is corruption, and
closing only the newest left the older ones open forever - the device then read
as returned while its custody history said otherwise.

Separately, usbcheckouts now records who handed a drive back
(checkinsso/checkinname, migration usb0004checkinidentity). Returning for a
colleague is a supported flow that the kiosk asks to confirm, but the row it
wrote attributed the check-in to the HOLDER, so the custody history and the
audit report both named somebody who was not there. Nullable and deliberately
not backfilled: copying the holder's badge into old rows would manufacture
evidence for the exact claim this stops making.

Four tests. Both guards verified by planting: strip the condition out of either
UPDATE and its test fails.

7f6aaf2e64 Gate the USB kiosk the same way, and make an unreachable setting a test failure
The USB kiosk had a feature flag and nothing else. A flag is a decision, not a
credential: with the kiosk on, anyone who could reach the app could move a drive
between checked-out and checked-in and sign it with a badge they guessed. Same
reasoning that closed the parts kiosk, smaller blast radius - which is why
Darkwing did not raise it and why it was worth asking about anyway.

Both kiosks now share one mechanism. The device token moved out of the
printedparts api wrapper into a request interceptor that attaches X-Kiosk-Token
by URL prefix, with one localStorage key per kiosk - they are separate screens
in separate rooms, and a shared token would mean provisioning one grants the
other. claimKioskToken() is shared too, so both views take the token from a
?token= URL once and strip it from the address bar identically.

Then the part that matters more than either fix. I told you to set the new
settings in the UI, and that was impossible: every plugin settings page carries
a hardcoded key list, and nothing had added them. printedparts_kiosk_enabled,
printedparts_kiosk_token and usb_kiosk_token were declared, seeded and read
correctly, and rendered by no page - changeable only by writing SQL.

tests/test_plugin_settings_reachable.py now fails when any declared setting
appears nowhere in its plugin's frontend. It found seven MORE that were already
in that state, all pre-existing:

  collector_corporate_ranges          computers_configpolicies_enabled
  computers_machinelink_alerts        computers_quietreporthours
  geenforce_reportstaleminutes        printers_dashboardpercent
  warranty_expiringdays

All seven now have fields. I first parked them in a KNOWN_GAPS ratchet, then
fixed them and deleted the ratchet - a backlog list in a new check is a way of
agreeing the check does not apply yet. There is no backlog; the check is
absolute.

Two of my own mistakes on the way, both caught by tests rather than by reading:
the blanket rename of the USB guard also rewrote the call inside _kiosk_open, so
it called itself until the stack ran out; and the first version of the reachable
check skipped all 17 plugins because it looked for get_settings() when the
method is get_settings_defaults() - it passed by testing nothing, which is the
exact shape it exists to catch.

Suite 2336, frontend 316, build clean.

7c47ae1f7c USB kiosk: take and return a drive without a ShopDB login
The people who actually take USB drives are standing at the cabinet, and most
of them have no account here. Check-out and check-in were gated behind a login
that was not doing much anyway: both modes already attribute the action to a
scanned BADGE rather than to the signed-in user, so the login was gating the
screen, not the record.

/usb-kiosk is a full-screen touch page modelled on the parts kiosk, off unless
a site sets usb_kiosk_enabled - every route 404s until then, rather than 403,
so a disabled kiosk does not advertise that there is a door here. It works
against the self-hosted tables or an existing cmmc_usb database.

THE LIST IS THE TRADE. These drives carry no barcode, so unlike the parts kiosk
there is nothing to present and the screen has to offer a list - which exposes
more than a scan-first design, where you had to already hold a drive to learn
anything. So the list is not anonymous: an SSO comes first and must resolve to
a real person before any drive is named, which is the same bar taking a drive
already had to clear. It is a POST so the badge stays out of proxy access logs.
The main screen shows the caller's own drives, what is free, and a COUNT of
everything else; holders of other people's drives appear only behind a second
deliberate tap, so nobody reads the whole cabinet off a wall panel in passing.

A badge that resolves to no employee is REFUSED, unlike the signed-in route
which creates the user row. A checkout nobody can trace to a person defeats the
tracking, and at a kiosk there is no operator standing there to vouch for it.

Returning somebody else's drive asks first and then records the badge that was
SCANNED, so the log says who actually handed it back. That is the honest record
and it needs no change to a schema this app does not own. Refusing a mismatch
outright is a setting but not the default: a drive left behind by somebody on
leave would otherwise be unreturnable at the kiosk, which just moves the problem
to a person with a login.

The authz sweep caught these writes, twice - once for the two mutations and
again for the two list endpoints. Both are exempted with the reasoning written
out beside the parts-kiosk entry rather than silenced. The list endpoints are
POSTs that change nothing.

Verified by driving the real page: SSO on the keypad, tap Take, database moves.
