Nov 1, 2025November 2025 — mage project performance highlights: consolidated card data model, hardening verification for double-faced/transforming cards, and gameplay abilities enhancements. Key deliverables: Card Data Model Refactoring and Consolidation unified A–I transforming cards into a single class/file, reducing duplication and easing maintenance; CardScanner and Verification Enhancements strengthened double-faced/transforming card validation, introduced per-name/set checks, updated tests to cover both sides, and adjusted behavior; Gameplay Abilities Enhancements added/refined abilities across multiple cards to improve mechanics and player experience. Major bugs fixed and stability improvements: prevented abilities on the main card for double-faced cards, fixed verification gaps, and stabilized CardScanner by reverting a prior change. Overall impact: higher maintainability, more robust rule enforcement, and better test coverage, enabling faster, safer feature delivery. Technologies/skills demonstrated: Java/OOP refactoring, test-driven development, unit/integration testing, rule verification, and maintainable code architecture.

Feb 1, 2025February 2025 performance summary for magefree/mage: Delivered two new card mechanics expanding gameplay depth. Ketramose, the New Dawn introduces exile-based attack/block conditions and a triggered draw/life-loss when cards are exiled during the player's turn, supported by utilities to check exile state and count exiled cards. Full Throttle adds a new sorcery granting two additional combat phases after the current main phase and untapping all creatures that attacked at the start of each combat this turn. Refactoring and maintainability improvements include replacing an unnecessary custom hint class with ValueHint to simplify dynamic value handling and UI hints related to exile conditions. Commit traceability is strong, with targeted changes: Ketramose: cbb3012b056808fd8a1b94786d6acabad80204c6 and b9fa82f602ef138e16d5779cabf0da27496d1d14; Full Throttle: 14fd76fb182d558dfee27771e6295043794d1b9e.
