Cross-platform state divergence occurs when business logic, asynchronous side effects, and state mutations are intertwined with platform threading models.

Enforces strict 16KB (0x4000) ELF load segment alignment across all compiled C/C++ native shared objects (.so files) and build configurations targeted for Android 15 (API level 35) and above. Failure to align ELF segments on 16KB boundaries causes immediate mmap failures, dynamic linker aborts (SIGSEGV/SIGBUS), and application crashes on devices running 16KB page size kernels.

Android 15 16KB Page Size NDK Binary Alignment Invariant
Mandates that all native C/C++ shared libraries (.so) compiled via NDK, CMake, or bundled as prebuilts enforce strict 16KB (16384 bytes) ELF segment alignment.

Enforces strict compile-time actor isolation and Sendable boundary serialization between Swift 6 concurrency domains and Kotlin Multiplatform (KMP) C/Obj-C interop runtimes. Bridged Kotlin classes are inherently non-Sendable reference types managed by Kotlin/Native's garbage collector, making cross-actor propagation without explicit boundary adaptation a catalyst for runtime reference-counter corruption and Swift 6 compiler rejection.

Capacitor 7 Swift 6 Structured Concurrency Task Cancellation Invariant
Guarantees that native Swift structured asynchronous task hierarchies initiated across the Capacitor 7 JS-to-Native bridge are explicitly tracked and cancelled when the originating WebView context tears down, navigates, or dispatches an explicit cancellation call. Without structured task cancellation propagation, orphaned native tasks retain UI references and background workers, leading to thread pool starvation, Swift 6 concurrency actor isolation violations, and memory leaks.

KMP K2 Native ARC Reference Cycle & Deterministic Unbinding Invariant
Establishes deterministic lifecycle unbinding and weak boundary mediation between Kotlin 2.1 Native runtimes and Apple Automatic Reference Counting (ARC).

Android 15 introduces support for 16KB physical memory page sizes on ARM64 hardware, shifting away from the legacy 4KB page assumption. Shared libraries (.so) built with native NDK toolchains that fail to align ELF segments (PT_LOAD) to 16KB boundaries will trigger immediate dynamic linker crashes (dlopen failures) and SIGSEGV faults at runtime. Engineers must enforce strict 16KB linker alignment in CMake/ndk-build configurations, eliminate hardcoded 4KB page assumptions in native mmap/mprotect invocations, and ensure vendor prebuilts pass verification.

KMP StateFlow Telemetry Debounce & Conflation Barrier for Declarative UI
High-frequency streaming inputs (e.g., BLE packets, GPS fixes, sensor feeds, audio telemetry) emitted directly into shared Kotlin Multiplatform StateFlow pipelines saturate the main UI thread in Jetpack Compose and SwiftUI.

Tauri 2.0 Mobile Fine-Grained Capability & IPC Sandboxing Invariant
Tauri 2.0 replaces v1 allowlists with explicit, capability-based security contexts. In mobile environments (Android WebView and iOS WKWebView), sensitive native host API invocations and custom IPC commands must be bound exclusively to cryptographically pinned origin windows and explicit window labels rather than wildcard targets.

Android 15 16KB Page Size Native ABI Memory Alignment Guardrail
Android 15 introduces support for devices configured with 16KB virtual memory page sizes, breaking legacy native ELF binaries and memory-mapped operations designed exclusively for 4KB boundaries. Unaligned ELF segments and hardcoded 4KB offsets in NDK shared libraries cause fatal SIGSEGV crashes on load or runtime memory mapping.

Kotlin Native ARC-to-GC Reference Cycle Confinement
Eliminates catastrophic native memory leaks in Kotlin Multiplatform iOS applications caused by cross-runtime retain cycles between Swift ARC and Kotlin Native's Garbage Collector.

Deterministic Teardown of KMP Coroutine Flows on Swift Task Cancellation
Bridging Kotlin Multiplatform (KMP) Flows into Swift Concurrency AsyncSequences or Task scopes requires deterministic lifecycle propagation. Unbridged or naively wrapped KMP flows leak background Kotlin Job coroutines and platform resources on iOS when the parent Swift Task is cancelled.

React Native 0.76 Bridgeless Fabric C++ Shadow-Tree Synchronization Standard
Enforces strict mutation semantics and non-blocking JSI host object boundaries during concurrent asynchronous component mounting in React Native 0.76 Bridgeless architecture. Prohibits synchronous cross-thread UI mutations and unsafe direct ShadowNode access from JS runtimes that trigger C++ mutex deadlocks and layout race conditions in Fabric's commit lifecycle. Mandates state updates through the React scheduler and C++ StateUpdate pipelines to guarantee thread-safe layout trees.
Tauri 2.0 Webview Capability Matrix and Scoped IPC Token Isolation Standard
Enforces deterministic, window-isolated IPC capability matrices in Tauri 2.0 mobile and desktop architectures. Prohibits ambient native API exposure by mandating window-specific capability definitions and cryptographically verified, short-lived session scope tokens on all privileged native commands.

Tauri v2 Desktop & Mobile Security Standard
Guardrails for Tauri v2 cross-platform desktop & mobile apps: command capability security ACLs, safe IPC serialization, and isolation of OS native permissions.
Capacitor 6 Native Bridge & Offline Sync Standard
Conventions for Capacitor 6 hybrid apps: manage native plugin lifecycles, handle safe hardware back buttons, and implement offline SQLite/IndexedDB synchronization.
Flutter Riverpod 2.5+ Code Generation & AsyncValue Standard
Modern state management and dependency injection in Flutter using Riverpod 2.5+ code generation. Forbids legacy StateNotifierProvider; mandates @riverpod annotations, autoDispose lifecycle, and compile-safe AsyncValue.when() UI branching.
Apple App Store Review Guidelines & Privacy Manifest Standard
iOS production compliance guardrails for App Store approval. Mandates PrivacyInfo.xcprivacy manifests declaring API categories (User Defaults, File Timestamps), Sign in with Apple requirement when third-party OAuth is used, and App Tracking Transparency (ATT).
Android Keystore & EncryptedSharedPreferences Hardening
Hardware-backed security architecture for Android. Mandates AES-256-GCM encryption for stored user tokens and private keys using Android Keystore and Jetpack Security EncryptedSharedPreferences; forbids world-readable files.
