keble-payment 3.0.1

No project description provided

keble-payment

keble-payment owns payment provider integration schemas and helpers for Alipay, Stripe, and payment persistence used by Keble services.

Verified State

Checked on 2026-07-22 against pyproject.toml, keble_payment/, and tests on fix/admin-payment-integrity.

• Package: keble-payment 3.0.1
• Python: >=3.13,<3.14
• Critical deps: keble-helpers, keble-db, keble-exceptions, python-alipay-sdk, stripe, httpx
• Source roots: alipay/, stripe/, paypal/, schemas/, crud/, main/
• Public exports: provider modules, payment schemas, and main client/helpers.

Runtime Contract

• keble-payment 3.0.1 reuses the structurally equivalent legacy fulfillment index during startup, regardless of its old name. This keeps upgraded Mongo databases from failing with IndexOptionsConflict before APIs or workers start. Fresh databases create the canonical descriptive index name.
• keble-payment 3.0.0 makes one typed AdminBankTransferPurchaseCreate command the only prepaid-order creation contract. Callers can no longer override the invariant pair ADMIN_BANK_TRANSFER + BANK_TRANSACTION; simulation similarly derives ADMIN_SIMULATED + FAKE internally. This intentional public API break is why the release uses a new major version.
• Real bank references are normalized (Unicode, whitespace, and case) and protected by a partial unique compound index scoped to the receivable account. The request UUID remains independently unique and fingerprinted, so both bank-owned and client-owned idempotency identities are enforced.
• Fulfillment now leases PENDING work as PROCESSING, records attempts and a bounded last error, returns active leases without concurrent replay, and permits expired leases to be resumed from durable server state. Only the current claim can mark COMPLETED; interrupted effects return to PENDING.
• keble-payment 2.5.0 introduced EXPLICIT typed fake/real tagging. TransactionMethod.FAKE marks admin-simulated non-revenue payments; OrderKind (STANDARD / ADMIN_SIMULATED / ADMIN_BANK_TRANSFER) on OrderBase.kind is the CANONICAL fake-order detection — the note prefix from build_admin_simulated_purchase_note remains human audit text only. Legacy rows lack kind and default to STANDARD on read; the keble v3 backend startup migration (payment_fake_method) backfills fake-noted orders/payments each boot. Legacy maintenance lines 0.0.15.post1 / 1.2.4.post1 carry the same FAKE enum member because payment rows live in a shared Mongo (v1/v2 backends enum-validate reads). adeactivate_admin_simulated_paid_orders_for_owner filters by kind and can never touch ADMIN_BANK_TRANSFER (real) or STANDARD orders.
• Receivable (money-in) bank accounts are centralized: ReceivableBankAccount* schemas + __keble_payment__receivable_bank_account__ collection + OrderClient.acreate/aget/alist/aupdate_receivable_bank_account (ACTIVE/INACTIVE disable-never-delete; historical bank_transaction rows link via the new BankTransactionBase.receivable_account id and keep the denormalized recipient_bank_account snapshot).
• acreate_prepaid_order(create=...) records REAL admin bank transfers end to end: required bank reference and receivable account, optional service identity, account status/currency/marketplace validation, exact paid_at, paid-order Redis cache, and payment-success callbacks. Recovery uses aresume_prepaid_order_fulfillment(request_id=...) and alist_recoverable_prepaid_orders(...); callers never reconstruct financial payloads from browser state.
• keble-payment 2.4.3 writes payment, cancellation, deactivation, and coupon comparison instants from the shared aware UTC clock. Never persist a naive local datetime.now() value: Mongo interprets naive values as UTC and can shift Asia/Shanghai payment times eight hours into the future, hiding a newly paid membership from enabled-period queries.
• keble-payment 2.4.1 converts PayPal decimal strings through exact Money.from_major_units / Money.to_major_units APIs. Provider output uses each currency's audited scale (JPY 0, USD 2, BHD 3) instead of a hard-coded two-decimal formatter; unrepresentable precision fails before payout.
• Alipay CNY transfer, WAP checkout, real notification, and admin-replay amounts use one immutable AlipayAmount schema. Provider values remain decimal text; no amount crosses binary float or truncating int(value * 100) conversion.
• Provider API details stay in provider modules. Backend checkout flows should consume package schemas and helpers rather than embedding provider payloads.
• Stripe stored models support optional stripe_account for multi-account handling; preserve that field across schema changes.
• Tests must not perform live payment requests in the local-full or portable-offline suites. Provider fixtures/assets belong under tests and must stay deterministic.
• Enabled provider live tests fail on provider request/schema errors; skips are only for missing live-test preconditions such as credentials or test price IDs.
• Reusable test settings and asset helpers live in keble_payment.testing.
• Payment tests resolve shared test env values through keble_db.testing, so backend-level .env values can be reused without duplicating secrets in this package.
• OrderPricingPolicySnapshot is the immutable paid-order audit shape for service pricing policies. The snapshot records the selected policy/tag, original/base/deal prices, currency, validity window, and optional linked claim clue so backend callbacks can consume limited deals only after success.
• Coupon histories snapshot currency, marketplace, and normalized tag/contributor attribution at payment success. Multiple tags split 10,000 basis points with deterministic largest-remainder allocation, so coupon/tag/contributor totals reconcile exactly.
• CouponListQuery/CouponPage own server search, sort, and pagination. Coupon search uses coupon_search_text_idx; attribution review uses attribution_status_created_desc_idx; supported sort fields have explicit indexes.
• CouponPerformanceQuery is the only reporting contract. It uses closed-open time ranges, IANA timezones, DAY/MONTH/TOTAL buckets, and exact Decimal output grouped separately by currency and marketplace.
• Historical attribution changes are explicit human-approved backfills through abackfill_coupon_history_attribution; never infer current tags during reports.
• Mongo and Redis integration tests must use per-test namespaces/databases and cleanup, not broad session-level deletes against shared databases.
• Executable tests stay under canonical layer roots: tests/unit, tests/integration, tests/live, tests/contract, tests/evals, and tests/db_stack.

Side Effect If Changes

• Backend checkout, membership upgrade, payment callback, and admin order routes depend on these provider schemas.
• Frontend purchase success tracking depends on backend payment state derived from this package.
