fix: keep IAPKit response changes from breaking shipped SDKs - #321
Merged

Conversation
IAPKit's purchase states, client payload formats, and verify stores are declared three times: kit's persisted Convex enum, kit's OpenAPI response table, and the GraphQL schema every SDK generates from. Nothing compared them, and kit deploys from main on its own workflow, so a kit-only change could put a value on the wire that already-published apps cannot decode. Adds scripts/audit-kit-spec-contract.mjs plus its own tests, wired into the unconditional Audit SDK Parity CI job and the pre-commit mirror so it runs whichever side of the contract moved. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
verifyPurchaseSuccessResponseSchema only fed describeRoute, so the documented shape and the emitted body could drift apart in silence. The handler typed state as a plain string and passed whatever Convex returned straight to c.json, and the apps decoding it cannot update their parsers. Responses now pass through enforceVerifyResponseContract before they are sent. Metadata outside the contract is degraded rather than published: an unpublished state becomes UNKNOWN, and an unparseable productId, environment, or clientPayload is dropped, because several SDKs reject an otherwise valid receipt on those fields. isValid is never rewritten. A verdict that stays malformed after degradation returns 500 instead of a body no SDK can trust. Violations log field names only. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
isValidState decides what every published app unlocks, and IAPKit deploys from main without an SDK release, so changing it changes live behavior for existing users. The per-state tests covered today's values but a state added later would simply go untested. Pins the entitling set as a whole so a new state cannot default into either answer unnoticed, and adds a golden table for mapAppStorePurchaseState, which had one case against nine Google ones. Documents the /v1 response contract in kit's CONVENTION.md: additive only, enum values are spec changes, isValid is the entitlement gate, and the emitted body is validated. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The audit read source text with regexes that could agree over a drifted repo, and both failure modes were reproduced. A bare `format:` anchor matched the first such key anywhere in the file, so a second schema declared above the real one made a `yaml` client-payload format pass. The kit-side parsers also counted values inside comments, so commenting out a state row left the audit green while the runtime union — now the allowlist enforceVerifyResponseContract degrades against — silently rewrote that state to UNKNOWN. Anchors are qualified by their owning declaration, an ambiguous anchor now fails loudly, comments are stripped, and an empty parse is an error instead of a vacuous match. The guard also only ran in ci.yml, while deploy-kit.yml is what ships kit from main; its verify job now runs the audit before the deploy gate. The malformed-verdict 500 returned after the verify outcome was set, so one log line reported statusCode 500 next to isValid true. The entitlement golden test pinned only the entitling subset, so a new state defaulting to non-entitling passed unchanged — it is now an exhaustive record the compiler forces someone to classify. Documents what the audit does not cover: kit declares the client-payload format set in five more places and the environment pair in two, split across its server/convex tsconfig boundary. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
IAPKit deploys from main while every SDK that decodes its response is frozen inside apps already on the stores. Optional metadata was parsed fail-closed in six places, so a value IAPKit added later would reject a purchase the store had already confirmed. `environment` is String in the spec, not an enum — Apple's App Store Server alone names Sandbox, Production, Xcode and LocalTesting, and kit already decodes and stores Apple's value without exposing it yet. Re-deriving the Sandbox/Production pair in five SDKs duplicated a constraint IAPKit owns and enforces, so the SDKs now forward the string and only drop a non-string. `clientPayload` is optional enrichment, and receipt verification is the security boundary, so an unreadable payload is dropped rather than thrown. Its format is matched against the generated enum instead of a hand-copied literal set, so a format stays readable once Types regenerates. Flutter and kmp-iap were re-validating results the native layer had already normalised, which defeated the native fix entirely: both dropped their duplicate gates, Flutter degrades an unknown state to Unknown, and kmp-iap's Android paths no longer re-impose a fail-closed decode or let a raw IllegalArgumentException escape a suspend function. kit-api's cache rejected an unrecognised format, which evicted the entry, stopped ETag revalidation from ever being sent and broke offline reads — for a value the live path already passes through untouched. The parity audit pinned the old fail-closed strings; its needles now pin the fixed contract while still proving environment is wired end-to-end. Verified: swift build + tests, expo-iap (432) and react-native-iap (580) suites, gql (174), kit (286), both audits. Android, Flutter and KMP have no local toolchain here and are covered by their CI jobs. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The verify contract can only be evolved safely if the server knows which generation of client is still calling it. Nothing carried that, so a decision to add a response value had to be made blind. Native verify requests now send `X-OpenIAP-Spec` with the spec version the build was compiled against, and kit records it on the structured verify log line. The value is reported, never negotiated: it is shape-checked and bounded before it reaches a log line, and no code branches on it, so an SDK cannot change how its receipt is verified by claiming a version. Apple reads it through a new non-fatal accessor. `OpenIapVersion. specVersion` traps when the bundled openiap-versions.json is missing, and it has no callers today, so putting it on the purchase path would have introduced a crash in exactly the code this branch is hardening — the resource is bundled differently by SwiftPM, CocoaPods and the xcframework. The header is omitted when the version cannot be read. Android reads it from a BuildConfig field derived from the same file the build script already parses. Request construction moved into a testable helper on the Apple side. Scope: the two native clients, which serve the verify path for React Native, Expo, Flutter, KMP, Godot and MAUI. The Vega/Fire OS JavaScript fallback calls IAPKit directly but has no version constant available without new sync plumbing, so it does not send the header yet.

Two pre-existing guards pinned the fail-closed behaviour this branch removed, and both broke CI: two Flutter tests asserted that a malformed client payload and a non-string environment throw, and kmp-iap's IapkitBaseUrlBridgeTest asserted the iOS source still contains the Sandbox/Production literal pair. All three now pin the fixed contract — the receipt survives and the metadata is dropped. kmp-iap's Amazon path still round-tripped through the generated fromJson, which throws on a clientPayload format its Types.kt predates, so an unreadable payload took down a confirmed purchase. It now maps field by field like the Play path, degrading the payload to null. The spec docstring for `environment` said only what IAPKit emits, not what SDKs must do with it — which is exactly the mistake five SDKs made. It now states the field is deliberately String and must be forwarded opaquely, regenerated across all eight languages. The Swift header test compared the header against the same accessor that produced it, so it passed green while sending nothing. Strengthening it exposed a real pre-existing defect: SwiftPM copies packages/apple/Sources/openiap-versions.json as the symlink it is, and that symlink dangles inside the built bundle, so Bundle.module resolves nothing and OpenIapVersion returns nil under SPM. Nothing had noticed because the accessor has no other callers. The test now pins the true contract — header present exactly when the version resolves, carrying a semver when it does — and the omission is graceful precisely because the accessor was made non-fatal.

The 500-path outcome reset replaced the whole outcome, dropping
`stableRejection` — the store's own provenance, which the replay guard
needs to arm its cooldown for a genuinely revoked receipt. It now resets
only the reported verdict and keeps that provenance.
Three strings that must agree across boundaries had no test. The
malformed-verdict log line is now asserted from the captured stdout
record, so the fix above cannot silently regress. `X-OpenIAP-Spec` is
driven through the middleware from the wire, so the one name shared by
kit, openiap-apple and openiap-google is pinned on all three sides. The
Vega parity needles now include the line that actually puts `environment`
on the returned object, matching the end-to-end proof the other five
platforms already carried.
The audit anchored against raw source, so a comment added between
`v.object({` and `format:` would have made the anchor miss and blocked
the kit deploy over a documentation edit — comments are now stripped
before anchoring, with a test. Its parsers signal drift by throwing, and
those throws bypassed the operator guidance the audit prints; they are
caught and reported as failures instead.
Android dropped an unreadable environment silently while Apple logged
it, and a lambda parameter shadowed its enclosing function parameter.

🛠 bugfix
Comments across the branch narrated the change and its reasoning at paragraph length, against the one-line default in AGENTS.md. The rationale belongs in these commit messages; what stays in the code is the constraint a reader cannot see. The Swift header test still compared the header against the accessor that produced it, and a skeptic confirmed by deletion that it passed with the header emission removed — under SwiftPM the accessor is nil, so it was nil == nil. The version is now injected, with both arms asserted. The 500-path outcome reset preserved an explicitly flagged rejection but still overwrote `state`, which the replay guard also derives stability from, so an INAUTHENTIC verdict that tripped the same path lost its cooldown. Stability is now resolved before the reset, and a test that fails without it drives the same payload twice for a 500 then a 429. kmp-iap's Amazon verify lost its error translation when the round-trip decoder was replaced, letting a raw Android OpenIapError escape a suspend function documented to signal through PurchaseException. Its mapping was also a byte-for-byte duplicate of the Play path; both now call one androidMain helper, pinned by the parity audit and the bridge test. Also: the audit's throw-to-guidance path has a test, and the published types page carries the forward-opaquely rule the spec docstring gained. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`withMappedOpenIapError` only catches the typed Android OpenIapError, but the validator also throws IllegalArgumentException for a malformed options shape, so that still escaped a suspend function whose every other exit signals through PurchaseException. Now caught broadly, matching the Play sibling. Corrects the previous commit message: it said this path "lost its error translation when the round-trip decoder was replaced". It did not. `git show origin/main` shows the call was bare there too, so no translation was ever removed — the earlier commit added coverage for the first time, and this one completes it.

The rules this branch enforces in code were nowhere a developer could read them. Without that, the natural thing to write in an app is a switch over the values that exist today, which is the pattern that breaks the next time IAPKit adds one. Adds /docs/kit-compatibility covering why the policy exists (IAPKit, the SDK you compiled against, and the build on a user's device move on separate clocks, and the last has no upper bound), what IAPKit guarantees, what each SDK does with a value it does not know, the X-OpenIAP-Spec header, how CI enforces it, and what to do in app code.

`OpenIapVersion` read `openiap-versions.json` out of the bundle at runtime, and that resource is a symlink to the repo root. SwiftPM copies a resource symlink verbatim, so it dangles inside the built bundle and `Bundle.module` finds nothing — the accessor returned nil under SwiftPM and `specVersion` would have trapped. Nothing had noticed because it had no callers until this branch added one on the purchase path. `sync-versions.sh` now generates `OpenIapGeneratedVersion.swift` from the same JSON, so the version is a compile-time constant that resolves in every distribution channel and cannot fail. The symlink stays as the SSOT, the runtime lookup and its fatalError are gone, and the optional accessor this branch added is no longer needed. The parity audit pins the generated values against openiap-versions.json. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`iapkit_set_client_payload` validated `format` with a zod enum, which is a runtime check, so the MCP server rejected a format IAPKit itself would have accepted.

Rethrow CancellationException before the generic handler on both kmp-iap verify paths. The catch this branch added to the Amazon path, and the pre-existing one on the Play path, converted a cancelled coroutine into PurchaseVerificationFailed and emitted a false purchase error. Declare X-OpenIAP-Spec as an optional OpenAPI header parameter so Redoc shows it, rather than describing it only in prose. Describe environment as the opaque provider-defined string it is, with the Amazon values as current examples rather than an exhaustive set.

The contract audit only read the response schema, but kit declares the client-payload format set in four more files on the write path. A format added there and not to the response schema is accepted on write and then silently dropped on read by enforceVerifyResponseContract. The audit now parses every declaration — valibot union, Set literal, and TypeScript union type — and compares each to the spec, with a test that fails when a write-path-only format is introduced. ios.ts cast Apple's environment to the Sandbox/Production pair the receipt validator requires, but Apple's Environment enum also defines Xcode and LocalTesting, so the cast was a lie that Convex would reject at the boundary. A shared helper narrows instead: anything that is not Production is a non-production purchase. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Review notes — two follow-ups, neither blocking. 1.
2.
That matches the documented degrade policy and is far better than failing the receipt, but it does mean the emit side is now stricter than the contract the spec publishes. Flagging it so the asymmetry stays a decision rather than becoming a surprise later. Minor: the GDScript doc comment picked up a double space from newline collapse — Verified the main risk: |
Keep client payload formats type-safe when newer servers add values. Generate whitespace-clean blank doc comments and align the spec header documentation with the compile-time implementation.
