New concepts/printer-usb-transport.md (the seam, usblp char device,
reachability-only status, threat model). open-questions #14: confirm the
on-site printer is USB and bake the usblp + udev write-access rule into the
appliance image (provisioning, not app code; unverified on hardware). Updated
rongta-printer.md (USB transport note), index.md, log.md.

After a completed payment the customer always gets a transparency record:
entry time, payment time, duration parked, amount + tender. One shared
ESC/POS renderer (renderReceipt + ReceiptData in @parking/devices), two
modes: VOUCHER = those figures PLUS the scannable Code128 barcode and an
emphasised walk-back-grace line, so the one slip both proves payment and
self-exits at a distant exit reader (replaced the old barcode-only voucher);
STANDALONE = detail-only, auto-printed at payment when no voucher is issued.
Figures fold from the SIGNED ledger (latest payment event); printed on the
booth printer (failover to dispenser). Best-effort: a printer fault never
blocks the exit that already happened — the modal shows a note and offers
"Reprint receipt".
Server: booth-print.ts printPaymentReceipt() + receiptFigures(); routes
POST /api/voucher (voucher) + new POST /api/receipt (standalone/reprint).
Both ESC/POS drivers gained printReceipt(). Web: BoothPayModal auto-prints
after a non-voucher payment + reprint button; api.ts printReceipt().
CP852 fixes found on a real printout: (1) uppercase Ë was mapped to 0xEB
(that's ű) — correct byte is 0xD3; (2) Intl.NumberFormat injects a NO-BREAK
SPACE (U+00A0/U+202F) that isn't in CP852 and printed as "?" — line() now
normalises it to a plain space ("1000 Lekë"); (3) grace line wrapped
mid-word — split into two short lines.
Full build green; both receipt modes render-verified; routes live.

The rongta-printer "Deployment" section still described a single
2026-06-14 unit. The live site now runs two: entry-dispenser 10.0.10.9
(Cashino, `cashino` ping-only driver) and booth-receipt 10.0.10.10
(Rongta, full status-page monitoring). Follow-up to 3e6773a.

Builds out subscription credentials on top of the rename.
- Operator chooses the credential type; only QR is live (RFID shown disabled
"soon"). Backend/schema keep accepting both — re-enabling RFID is UI-only.
- QR codes are AUTO-GENERATED server-side (SUB-<base32>, crypto-random,
globally-unique-checked) — the customer/operator never picks the value.
RF stays operator-entered (the physical card id). Reader output decided =
TCP/IP full string (Wiegand-numeric fallback noted).
- Multi-month: form takes a `months` count → server sets validTo =
validFrom + N months (day-clamp); one record/one window; total = N×monthly.
- The QR card is PRINTED so the operator can hand it over: real ESC/POS 2D QR
(GS ( k) added to the Rongta driver (printSubscriptionCard); auto-print on
create (best-effort — never fails the create; returns {printed,printError})
+ reprint via POST /api/subscriptions/:id/print and a "Print code" button.
Verified via buildServer+inject incl. a TCP capture of the on-wire QR bytes
(autogen+uniqueness, Jan31+3mo→Apr30, auto-print, GS ( k QR with embedded
code, reprint, no-QR→409). Updated wiki (subscription, rongta-printer). No
migration.

Add the rongta PrinterDevice driver (ESC/POS over raw TCP 9100) and the
device-agnostic pieces around it:
- Roles + failover: each printer declares a role (entry-dispenser/booth-
receipt) and failoverRank; printer-routing.ts picks the best healthy printer
and falls back outside->booth for entry tickets (never the reverse).
- Live status: MonitorableDevice.readStatus()/PrinterStatus capability. The
Rongta driver scrapes the device's own /prn_stat.htm (Cover/Cutter/Paper
End/Near End/Off-Line) rather than hand-decoding DLE EOT, whose reply bytes
on this clone don't match the canonical ESC/POS bit layout (verified on
hardware) -- avoids a false-healthy. Maps to ready/degraded/offline, fail
safe on an unreachable or unexpected page.
- Server PrinterMonitor polls enabled printers (PRINTER_POLL_MS, default 5s),
caches latest, emits "printer-status" on change. Exposed via
GET /api/printers/status and an SSE stream for the booth UI.
Verified against 10.0.10.6: ready when healthy, offline when unreachable
(no throw), bus emits on change and suppresses unchanged reads.
Wiki: new rongta-printer entity, printer-roles-failover and
printer-status-monitoring concepts; BOM/index/log updated.
