Owner

ONE play managed checkout now sends an authenticated server-issued intent in developerPayload. SDK success carries purchase-token evidence with empty entitlements; the backend independently queries API V7, binds owner/application/environment/market/deployment/product/idempotency, and records the replay-protected grant before consume or acknowledge. Finalization retries use the original durable evidence and never charge again.

Add fixed-origin OAuth/API transport and signed PNS 3.1.0 recovery with an independent API refresh. PNS can recover a purchase after the client closes and delivers verified cancellations to a required game-owned hook. Production integrations must provide durable intent/ledger/reconciliation storage and an atomic cancellation fence plus revocation policy; this PR supplies the verified ports and documented integration, not a game-specific HTTP backend or refund policy. Subscriptions remain unsupported, and sample monetization stays disabled without authenticated server ports.

Product lookup handles independent feature support, 20-ID batches, partial/reordered results and currency-labelled prices. Native payment and ad ownership are shared. The common optional commerce.presentation contract lets the runtime release confirmed native closure separately from financial completion and retain uncertain/timeout outcomes. Private and generated starters map ONE play products and accept authenticated commerce/reward ports, with aligned capability manifests and acceptance guidance. PNS stays pending without completed finalization; busy native SDKs explicitly report a request as not-started. Purchase and signed SSV time bounds tolerate five minutes of server/provider clock drift.

Validation: full pnpm check, package build, configuration/catalog/ad/target validators and adapter effective smoke; 49 focused adapter/runtime tests; token/intent binding, ledger-before-consume retries, acknowledge, signed PNS tampering/replay/cancellation/orphan-purchase tests; monetization recovery regression; external packed runtime/type consumer; package tarball export smoke; ONE play production build and artifact smoke. OCR reviewed all 30 changed files with zero skipped files or unresolved findings. Changesets cover adapter-browser, game-services, platform, game-runtime, CLI and create-game.

Actual ONE store app ads/payments and hosted execution validation still require the maintainer's issued ONEconsole IDs/credentials and game-owned backend. PR #300 and #302 are already merged; release PR #301 must merge last, after this feature PR and any other reviewed feature work.

📝 Walkthrough

Walkthrough

This change adds ONE play managed purchases across the browser adapter, game-services package, platform contract, and runtime integrations. It supports authenticated checkout intents, independent server-side purchase verification, consume or acknowledge finalization, and signed PNS processing. Subscriptions remain unsupported.

ONE play managed purchases

Layer / File(s) Summary
Commerce and platform contracts
adapters/browser/src/oneplay-sdk.ts, packages/platform/src/index.ts, packages/game-services/src/types.ts, packages/game-services/src/client.ts
Adds SDK purchase and product-detail types, a shared purchase-presentation event, and oneplay as a game-services commerce target.
Browser checkout and product details
adapters/browser/src/oneplay-commerce.ts, adapters/browser/src/oneplay.test.ts
Adds product-detail batching, server-issued checkout payloads, idempotent purchase handling, purchase outcomes, entitlements, and optional restore. Tests cover checkout, presentation, product mapping, and error outcomes.
Gateway and runtime integration

Merge Risk: 🔵 Low · up to 29f0c

A small clock difference between ONE store and the game server can reject a legitimately paid purchase shortly after checkout, and the player never receives it. This is a narrow edge case with a one-line fix. It is otherwise mergeable.

I’m a rabbit with a checkout plan,
A signed note tucked safely in my span.
The ledger marks the purchase true,
Then consume or ack can follow through.
PNS brings news; I hop to check,
And rest with carrots by the deck.

purchase-intent validation to allow the same 300,000 ms clock-skew tolerance as
the upper bound. Adjust the `purchaseTime: at - 1` test case in
