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.

Replaces the two `pricing_*_tiers_json` blobs and five `first_session_discount_*`
keys in app_config with dedicated `pricing_tiers` and `pricing_promotions`
tables plus matching `_history` audit tables. UUID PKs, UNIQUE(mode, minutes)
natural-key constraint, optimistic-lock via `updated_at` token returning 409
STALE_WRITE on conflicts. Every mutation writes a history row capturing the
operator (changed_by from request.auth.userId) and change_kind.
CC SettingsPage replaces the JSON-textarea editors with per-row tables —
add / edit / soft-delete / reactivate / reorder, plus a buffered first-session
discount form with the same optimistic-lock contract. `minutes` and `mode` are
read-only on edit since they form the natural key; operators soft-delete and
recreate to change duration.
Stage 5 fixes a latent leak: `client.payment.routes.js` had its own local
`readDiscountConfig` that still read from app_config — would have silently
fallen to hardcoded defaults once the legacy rows were deleted. Now reads from
pricing_promotions via the shared service helper, so CC edits to the first-
session discount affect actual payment pricing on the next request.
Customer-facing GET /api/client/chat/pricing shape unchanged (id values are
now UUIDs instead of "5"/"12"/"60" but lookups happen by (mode, minutes), so
no app changes needed). 27 new backend tests, all green.
