fix: keep every store working in minified release builds - #490
Conversation
No Android build in CI ran R8: the library and Example disable minify, and every assemble step is a debug build. An app's release build is where a class R8 cannot resolve, or a pin that links the wrong store SDK, first shows up. verify-release-consumer.sh publishes the Play, Horizon, and Amazon artifacts locally, then builds a minified release app for each through the shared store resolver: no pin, -PopeniapStore=horizon, and ORG_GRADLE_PROJECT_openiapStore =amazon. Each case asserts the resolved store, that releaseRuntimeClasspath and R8's mapping carry only that store's SDK, and, for Amazon, that the manifest receiver keeps its name in the dex.

The new minified release check failed on its first CI run. R8 stops every minified Horizon build: the Horizon platform SDK references javax.annotation.Nullable without shipping it. Amazon builds, but R8 renames the Appstore SDK's classes and strips the fields it fills by reflection (none of 71 survive), so its request pipeline cannot run in a release app. Each flavor now ships the rules its SDK needs as consumer rules: a -dontwarn for the JSR-305 annotation on Horizon, and Amazon's documented keep rules on Amazon. The check now asserts that R8 renames no Amazon SDK class, in place of the receiver-only check, which passed while the SDK was broken.

OpenIapStore.enableBillingProgram looked up the Play module's method by name, because only the Play flavor defined it. Nothing calls that method directly, so R8 removes it from a minified app, and React Native's enableBillingProgramAndroid then only logs a warning: External Payments and Billing Choice never turn on in a release build. enableBillingProgram is now part of OpenIapProtocol; Horizon and Amazon ignore it with a warning, as they do for the other Play billing-program calls. The two other reflective lookups into openiap go too: kmp-iap constructs OpenIapModule directly, and React Native reads the Billing Choice fields directly. Both exist in the published 3.6.0. The parity audit now rejects reflective lookups in openiap's shared source and in the framework bridges. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017jh5cR6NE24PUBfP9fAEF9
The Play module reaches 22 Play Billing classes and 37 methods by name, so it still runs when an app pins an older billing version. Most have no direct call, so R8 may drop or rename them in a release build, and the feature then fails quietly: External Payments, Billing Choice, external links, user choice billing, service reconnection, and a subscription's suspended state. The release check reads those names from the module's source and fails when the Play release APK lacks one. It reads the APK with dexdump.

The card ships with this PR, written as published: openiap-google 3.6.1 and the framework patch releases that pick it up, with their expected tags. The Android, Flutter, and KMP setup guides asked apps to add keep rules by hand. The store artifacts now carry the rules their billing SDKs need, so the guides say no rules are needed.

Release notes were written after every package published, then committed to main before the docs deploy. A PR that changes a published package now carries its guide updates and the release card for the next version, written as already published. After the train publishes, the release only checks each version and link, corrects the card if one differs, and deploys. The canonical rule is "Docs Ship With The Change" in knowledge/internal/05-docs-patterns.md; AGENTS.md, release.md, generate-doc, ship-release, loop-review, and review-self point to it.

…ntations compile Only Google Play acts on it, so an OpenIapProtocol implementation written against 3.6.0 keeps compiling without overriding the new member. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017jh5cR6NE24PUBfP9fAEF9
The Play module also matches eight Play Billing listener callbacks by method name. If R8 renamed one, the callback would never complete its operation, so the release check now reads those names too and fails when the APK lacks one. The check also runs on bash 3.2, the macOS default. The parity audit pins originalExternalTransactionId inside the user choice listener, which the developer-provided listener's identical line no longer satisfies. Its reflection scan skips every flavor test folder. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017jh5cR6NE24PUBfP9fAEF9
A release card now merges with its PR, before its packages publish, so a docs deploy in between would show users releases that don't exist yet. The deploy now refuses a release page that links an unpublished tag. Seven older links that already 404 are listed as known until their cards are fixed. The rule applies to PRs into main, since the next branch carries no stable cards. A train that stops partway resumes or trims its card before a deploy, and the post-release review and direct main commit run only when the card needed a correction. The docs audit rejects a Planned Package Releases heading, and stale text that still said to link a tag only after it exists is updated.

No kmp build ran R8, so nothing caught a kmp-iap release build that R8 can't finish. The example's release build is now shrunk like a shipped app, and kmp CI builds it for Play, Horizon, and Amazon against this repo's openiap-google.

kmp-iap compiles its Play Billing implementation into every Android variant, with Play Billing compile-only on Horizon and Amazon. R8 therefore stopped every minified Horizon and Amazon app on the missing Play Billing classes, as the new release build in kmp CI showed. Those builds never run the Play code, so both flavors now ship a -dontwarn for Play Billing.

Release workflows push the tag before they publish and create the GitHub Release last, so a train that stops after its tag would still pass a tag check. The deploy now lists published GitHub Releases with gh instead. Two older Apple links, 2.1.6 and 3.5.0, have a tag but no release, so they join the known exceptions. The deploy test covers an unpublished link, a known historical one, and a failed release list. The release check also stops, with a clear message, when no dexdump is available. Under set -e the lookup exited silently before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017jh5cR6NE24PUBfP9fAEF9

…491) Follow-up to #490 from its last independent review. None of these blocked the merge. - `npm run deploy` passed its release-link check when it could not read the release page. It now stops when the page is missing or yields no links, and the deploy test covers a literal release link, which the old fixture only had on the allowlist. - `release.md`'s affected-set rule read only commits under a package path, so a library that only picks up a new native version looked unaffected. A library whose pinned native version moves now counts as affected, which is how the 3.6.1 train ships expo-iap, flutter_inapp_purchase, godot-iap, and maui-iap. - The `Planned Package Releases` rejection in `audit:docs` gets tests. - Stale lines are corrected in `04`, `05`, and `06` of `knowledge/internal` and in the release card's heading.
