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.

Splits the single mitra_ping_interval_seconds config (which conflated
"how often the app pings" with "how long until offline" through a
hidden ×3 multiplier) into two orthogonal knobs:
- mitra_stale_after_seconds (CC-tunable, app_config DB row): the
operator-facing offline threshold. What you set is what you get —
no multiplier. Default 45s (preserves today's effective grace at
the legacy 15s ping default).
- MITRA_HEARTBEAT_CADENCE_SECONDS (env var, default 30s): how often
the mitra app sends a heartbeat. Backend-fixed per deployment;
surfaced to the mitra app via /api/mitra/status.
Backend:
- config.service: getMitraPingConfig returns the new tuple
{require_ping, stale_after_seconds, heartbeat_cadence_seconds}.
Env parser handles blank/non-numeric → 30 fallback.
- mitra-status.service::autoOfflineStaleMitras drops the *3 and uses
stale_after_seconds directly.
- mitra-status.service::getStatus returns heartbeat_cadence_seconds
instead of ping_interval_seconds.
- /internal/config/mitra-ping PATCH validates
stale_after_seconds >= cadence, returns 422 with a clear message
("stale_after_seconds must be a number >= heartbeat cadence (30s)").
- migrate.js: adds mitra_stale_after_seconds default 45. The old
mitra_ping_interval_seconds key is left in place (vestigial) —
no live code reads it; safe to drop after one release.
Mitra app:
- status_notifier reads heartbeat_cadence_seconds, uses it directly
as the Timer.periodic interval. Defaults to 30s if missing (older
backend safety).
Control center:
- SettingsPage: renames "Interval Ping" → "Ambang offline", input
min={heartbeat_cadence_seconds}, shows the cadence as a read-only
value with explanation that it's env-controlled.
Verified end-to-end on dev backend:
- GET /api/mitra/status returns {…, heartbeat_cadence_seconds: 30}
- GET /internal/config/mitra-ping returns {require_ping,
stale_after_seconds: 45, heartbeat_cadence_seconds: 30}
- PATCH with stale_after_seconds=20 → 422 with cadence message
- PATCH with stale_after_seconds=120 → 200, persisted
- Env override (=60, blank, "foo") parses correctly.

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.

- Fastify public app now passes `trustProxy: true` so request.ip resolves to
the real client IP from X-Forwarded-For when behind Cloud Run / a load
balancer. Without this the per-IP rate limit was either useless or
collapsed all users into one shared LB IP.
- The `anonymity_enabled` config row + JS default + migration seed now
default to `false`. The flag is dead code (no business logic ever
consumed it) and the actual rule is simpler than the toggle implied:
mitras always see the customer's chosen call_name; only phone+email
are private. The whole feature is queued for rip-out as a separate
cleanup pass.
The per-IP OTP rate limit (10/hr) was also effectively disabled by
upserting `app_config.otp_max_per_ip_per_hour = 1000000` — a runtime
config change, not a code change. Per-phone (3/hr) + Fazpass cost
remains the real abuse gate.
