From cf60990a0a07f06bb6af5f844c83581f98d9849b Mon Sep 17 00:00:00 2001 From: Itodo-S Date: Mon, 27 Jul 2026 22:16:24 +0100 Subject: [PATCH 1/2] feat: implement issues #740-743 - ETL module, billing strategy pattern, context+hooks, contract modularization - #740: Extract ML service feature pipeline into standalone ETL module - Create ml-service/etl/ with extractors, transformers, loaders, pipeline, monitoring - Add Airflow DAG for pipeline orchestration - Add performance benchmarks - Add ETL testing framework and documentation - #741: Refactor billing engine to strategy pattern for pluggable pricing - Create backend/services/billing/ with PricingStrategy interface - Implement FlatRate, UsageBased, Tiered, and Dynamic pricing strategies - Add PricingStrategyFactory for strategy selection by plan type - Add PricingAnalyticsService for revenue metrics - Add comprehensive tests - #742: Refactor mobile app state management to context + hooks pattern - Create src/context/ with SubscriptionProvider and AppProvider - Create custom hooks for type-safe state access (useSubscriptionContext, useSubscriptions, etc.) - Add performance-optimized selectors to minimize re-renders - Maintain backward compatibility with existing Zustand stores - #743: Refactor smart contract to modular library architecture - Extract plan.rs, subscription_lifecycle.rs, payment.rs, admin.rs from monolithic lib.rs - Maintain full backward compatibility with existing public API - Preserve all existing tests and functionality - Improve code organization and maintainability ---

0f6a364060e8291c1a68050631f89bb0be586fb7 Mon Sep 17 00:00:00 2001 From: Itodo-S Date: Tue, 28 Jul 2026 19:50:08 +0100 Subject: [PATCH 2/2] fix: resolve all Rust compilation errors across contracts workspace MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Split StorageKey into StorageKey (core) + StorageKeyExt (extensions) to avoid soroban contracttype variant limit - Update storage bridge methods to accept Val instead of StorageKey - Make subscription storage helpers generic for both enum types - Fix subscription contract: oracle feature-gated imports, payment API (into_val/to_val), loyalty byte strings, Address comparison (deref), move-after-use bugs, type annotations, event_store comparisons - Fix oracle: add contracterror import, refactor chain-specific functions to use dedicated DataKey variants instead of Symbol::to_string() - Fix utils/merkle: u64→u32 vec indexing, Option wrapper - Fix audit: wrap event topic in tuple for Topics trait - Fix credit: undefined variable in next_wallet_id, u32→u64 cast - Add missing types to subtrackr-types (BillingSchedule, LoyaltyConfig, WebhookConfig, etc.) and Interval variants (BiWeekly, BiMonthly, etc.) - Gate all oracle-dependent code behind #[cfg(feature = "oracle")] --- .detoxrc.js | 14 +- .env.example | 36 + .eslintignore | 10 + .eslintrc.json | 30 +-
