v0.9.0 | Beta Candidate | July 21, 2026
A Python recreation of Atomic Games' legendary WWII tactical wargame — Beta Candidate with full SRP refactoring, real-mode E2E, and mature test suite
🟢 Beta Candidate: Core gameplay + cinematic effects + achievement system + dynamic shadows + projectile trails + SRP architecture cleanup + real SDL E2E validation + visual polish (death fade, screen flash, movement smoothing, UI transitions, weather overlay, shell ejection, button feedback). 6291 tests passing, 38-phase E2E user journey validated in real environment. Ghost feature audit complete — all critical rendering pipelines now active. Environmental audio activated, dirty rectangle optimization live, EnhancedRenderer split complete, ResourceCacheManager online. v0.6.11: 4 ghost modules removed (spritesheet_parser/operation_timeline/context_menu + tactical_ai_types type:ignore fix). v0.7.0: 3 half-integrated modules activated (weapon_jam/surrender_system/campaign_persistence) + TD-078 DDD layer fix (deployment_factory migrated presentation→services). v0.7.1: 19 orphan prototype modules classified via TD-077 (4 DELETE + 10 ARCHIVE + 8 ORPHAN pending v0.8.0+ integration). v0.7.2: INTEGRATE prep (ROADMAP doc sync + flaky benchmark threshold fix 100ms→130ms + 3 ORPHAN module smoke tests). v0.7.3: day_night_cycle interface compatibility fix (time_of_day renamed to time_phase returning TimeOfDay enum + new time_of_day returning float 0.0-24.0 per IDayNightCycle protocol + game_loop_updating caller adaptation for audio + shadow sync). v0.7.4: INTEGRATE prep (squad_group_manager test enhancement 5→35 tests covering 6 dimensions + psychology_system/squad_group_manager INTEGRATE design doc). v0.7.5: INTEGRATE complete (psychology_system wired into TacticalOrchestrator.tick() Phase 5 to filter refused orders by morale/suppression/fatigue + squad_group_manager wired into InputRouter for Ctrl+1
9 create / 19 quick-select + Minimap bounding-box rendering for active groups, 27 integration tests). v0.7.6: TD-077 remaining 6 ORPHAN modules fully integrated (path_preview + range_indicator wired into Minimap for movement path visualization and unit range circles + cover_seek_ai wired into TacticalOrchestrator.tick() Phase 6 for suppression-driven cover seeking + day_night_cycle activated via GameTime injection to leverage v0.7.3 pre-wired audio/shadow/weather adapters + vehicle_variant_generator + faction_variant_generator wired into unit_database build pipeline expanding templates 80→110, 75 integration tests). v0.7.7: P2 tech debt cleanup (4 F-level cyclomatic complexity refactors: generate_road cc=115→6, handle_player_command cc=73→4, generate_orders cc=68→19, draw_units cc=63→14, total E+ violations 22→18; radon baseline migrated from CI hardcoded BASELINE=23 to pyproject.toml [tool.radon] cc_baseline=18 for single-source-of-truth CI maintenance, pure refactoring no behavior change, 6291 tests passing zero regression).
