EnakGame phases 1-8 of docs/tasks-enakgame.md (EG-101 to EG-803), built on the
existing EnakPoint/EnakCoin wallet (docs/rfc-enakgame.md).
Foundation (phase 1)
- Migrations 000103-000106: games extended with organization, slug, status,
entry cost and result rules, old games archived (not deleted); budgets,
versioned reward configs, sessions and session rewards; the ledger types
GAME_SPEND_REFUND, GAME_REWARD and REWARD_REDEEM_REFUND; audit_logs.
- AuditLogger writes in the caller's transaction only.
- enakgame.limit.user_daily and global_daily organization settings.
Games and sessions (phases 2-4)
- Admin /marketing/enakgame: games, reward config versions (immutable but for
status, one ACTIVE per game), budgets with non-overlapping global periods and
a daily job opening the next month.
- Customer /customer/enakgame: start (Idempotency-Key, entry cost and config
frozen on the session), complete (result validation, reward engine, max_reward
cap, daily limits via game_reward_counters, one GAME_REWARD per budget),
automatic refunds for system errors and deactivated games, and a session job.
- Reward engine: FIXED, SCORE_BASED, OUTCOME_BASED, PROBABILITY (crypto/rand),
rounded down.
Vouchers and budgets (phases 5-6)
- Migration 000108 and 000107: vouchers, codes, redemptions, cost attribution;
Economy Guard counters.
- STATIC and CODE_POOL redemption in one transaction with the REDEEM PIN action;
realized cost traced through the lots to the budget that paid the reward.
- Budget metrics: realized cost, forecast, exposure and status. Migrations
000109-000110 add the wallet_lots indexes they need, built CONCURRENTLY.
Events (phase 7)
- Migration 000111: game events, each with its own EVENT budget. Event extras
stack per PRD §16 defaults, with event and per-customer limits.
External vouchers (phase 8)
- VoucherProvider contract, two-step PENDING redemption and a recovery job,
tested with a fake provider. No provider adapter is registered yet, so
EXTERNAL vouchers stay out of the catalog.
Not yet decided before release: reward rounding, event stacking, budget
exhaustion policy and thresholds (RFC §19.2). Migrations 000103-000111 have
not been run on any shared database.
Also fixes a leftover PAYMENT filter in a wallet test and a data race in a
test PIN fake.

EnakPoint can only be redeemed for vouchers now: it can no longer pay for
orders and is never cashed out (docs/enakgame-prd.md §3.2, EG-001,
EG-002). No order was ever paid with EnakPoint, so there is no data to
move.
Removed:
- POST /customer/wallet/payment-code, POST /customer/orders/:id/pay-with-points
and GET /orders/:id/point-payment/preview, with their processors,
repositories, services, handlers and tests.
- The point payment method type: paying, splitting and refunding with it,
the outlet filter on the method list, and the system-method guard.
- points and payment_code on CreatePayment; points_used and point_value
on payments; accepts_point_payment on the customer outlets.
- The outlet point_payment settings. A PUT that still sends them is
rejected as an unknown field.
- The EnakPoint split in the payment method analytics.
- PAYMENT and PAYMENT_REFUND from the wallet type rules. Tests that used
them as a generic EnakPoint debit use REWARD_REDEEM.
- The EnakPoint-paid part from the earning basis, which is
subtotal − discount again.
Migration 000102 drops the trigger, the point methods and their index,
the payments columns, and the outlet settings, and restores the method
type CHECK without point. payments.payment_method_id is ON DELETE
RESTRICT, so it fails rather than lose a payment made with EnakPoint.
The integration docs list the removed endpoints and fields, and the
EnakPoint & EnakCoin PRD and tasks note what is superseded.

Adds the expiry job (docs/prd-point-coin.md F12, PC-503).
Every 15 minutes it lists the lots whose expiry has passed and that still
hold something, the longest overdue first, 500 at a time, and expires each
in its own transaction through WalletProcessor.ExpireLot: lock the wallet,
read the lot again, and take what is left with an EXPIRE row pointing at
the lot, keyed expire:{lot_id}. The description is frozen as
"Kedaluwarsa: 130 EnakPoint dari Belanja #ORD-0098", using the amount read
under the lock. Lots expire at the end of their day, so none stays past it
for more than about a quarter of an hour.
It is safe on several instances and across restarts, keeping no state in
memory as OmsetMilestoneScheduler does. Selecting the lots FOR UPDATE SKIP
LOCKED, as PC-503 suggested, would lock a lot before its wallet and
deadlock against payments, which lock the wallet first; instead the
listing takes no lock, and the wallet lock plus the idempotency key make a
second instance find the lot empty or the key used and take nothing.
A lot that fails is logged and retried on the next run without stopping
the others. Each customer gets one FCM push per currency with the total
that expired ("180 EnakPoint kamu sudah kedaluwarsa.", type
WALLET_EXPIRED).

Adds GET /customer/wallet/exchange/preview?coins= and
POST /customer/wallet/exchange (docs/prd-point-coin.md F4, K3, PC-401).
The customer exchanges a multiple of the organization's coin_amount and
gets (coins / coin_amount) x point_amount EnakPoint, approved by their PIN
(K8). A malformed amount is refused before the PIN is checked, so it costs
no attempt. In one transaction the wallet is locked, EXCHANGE_OUT takes the
EnakCoin in K9 order and EXCHANGE_IN adds the EnakPoint; the two rows share
a group, point at each other and both freeze the rate in their metadata.
The EnakPoint are split over the EnakCoin lots they came from, each part
keeping its lot's expiry and pointing back at it, so exchanging cannot
extend a balance's life. The split takes floor(coins so far x rate) per
lot, which adds up exactly because the total is a multiple of coin_amount.
EnakPoint have no validity of their own until the expiry model is decided
(N4), so the EnakCoin lot is for now the only bound.
The Idempotency-Key header (or X-Idempotency-Key) is required. A retry
with the same key is recognised under the wallet lock and replayed with
the ids and rate the first attempt froze, even if the rate has changed
since; the same key for another amount is refused.

WalletProcessor writes the balance, the ledger row and the lots or
allocations together, which keeps SUM(ledger) = balance = SUM(lot
remaining) (docs/prd-point-coin.md §7.5, PC-104).
- Credit writes the ledger row and creates lots, each with its own expiry
and origin lot.
- Debit draws from the preferred lots first (a reversal's own lots, or the
lot being expired), then from unexpired lots in K9 order, and returns the
allocations with their expiry so CarryOver can give the receiving side of
a transfer or exchange the same expiry.
- DebitUpTo takes what the wallet has and reports the shortfall (F10, Q3).
- An idempotency key returns the first result; reusing it for a different
operation is an error.
- §8.1 is checked in code from one rule table, ahead of the database
constraints, so callers get a readable error.
Each method locks the wallet itself, after validating the input and before
checking the idempotency key, so correctness does not depend on the caller.
Operations on two wallets still call LockWallets first to keep lock order.
Unit tests run on an in-memory repository and check the §7.5 invariants
after every scenario; one more test runs the engine against Postgres when
TEST_DATABASE_URL is set.
