Backend
- payment_sessions → payment_requests rename across DB schema + 29 files
- payment.service.js becomes product-agnostic owner: EventEmitter +
Xendit wrapper + requestPayment / confirmPayment public API; legacy
aliases retained for existing chat callers
- Webhook handler at POST /api/shared/payment/webhooks/xendit, with
constant-time token verification (8 vitest cases)
- Server-driven pairing: payment.service emits
payment_request.confirmed → pairing subscriber starts the blast.
Legacy POST /chat/request still works during the cutover.
- Reconciliation sweeper extended (re-emits events for confirmed rows
with no chat session)
- SIGTERM drain + startup reconciliation pass in server.js
Customer app
- waiting_payment_screen opens xendit_invoice_url via
LaunchMode.inAppBrowserView
- searching / no-bestie / targeted-waiting / pairing-notifier updated
to consume the new payment_request_id contract
- pending_payments_provider + bestie-unavailable dialog migrated
Dev / testing
- XENDIT_ENABLED=false is the safe default; .env.example documents the
four new vars
- backend/.dev/xendit-fake-webhook.sh exercises the handler without
ngrok
- 90/92 backend tests pass (two pre-existing session-timer flakes,
unrelated); client_app analyzer clean
- requirement/phase5-xendit-plan.md is the canonical reference
Stage 8 (live E2E) blocked on Xendit test-mode keys. The dashboard's
single-webhook-URL constraint will be worked around via a self-poll
script next session.

OTP screen rewrite: 6 rounded boxes, auto-advance focus, auto-submit on the
6th digit, hardware-backspace on empty boxes (intercepted via Focus.onKeyEvent
since TextField.onChanged doesn't fire on already-empty input), resend
cooldown sourced from /api/shared/config/otp, and an inline error message
under the boxes instead of a SnackBar.
Several bugs fixed inline that surfaced during testing:
- ref.listen inside build() accumulates listeners on every rebuild — the
resend countdown's per-second setState was piling up duplicate listeners
so one error triggered N callback fires. Moved to ref.listenManual in
initState; subscription disposed in dispose().
- RouterNotifier was calling notifyListeners() on every auth state change
including AsyncError, which rebuilt the Navigator/Scaffold mid-snackbar
and visually duplicated the error toast. Now skips AsyncError and
same-data-variant transitions.
- ScaffoldMessenger.showSnackBar from a Riverpod listener callback could
still render twice even with hideCurrentSnackBar — replaced with an
inline error widget to sidestep the snackbar machinery entirely.
- register_screen now uses context.go instead of context.push for the
OTP route, so re-submitting the phone form doesn't stack multiple
OtpScreen instances with active subscriptions.
Lockout UX: AuthErrorInfo wraps the error message + code + retry_after_seconds
parsed from the backend's structured error response. On rate-limit codes
(OTP_COOLDOWN, OTP_RATE_LIMIT_PHONE, OTP_RATE_LIMIT_IP), the OTP screen
extends "Kirim ulang kode" cooldown to match the server's wait, and the
register screen disables "Kirim OTP" with a "Coba lagi dalam …" countdown.
formatCountdown() in core/constants.dart renders Xd under 90 seconds and
Xm Yd above (clearer than raw seconds for long lockouts).
