BioCraft: Alien

## [1.1.0] - 2026-08-03 (Stage 3 Laboratory Complete)

### Laboratory Framework
- **✅ COMPLETE**: Stage 3 laboratory framework (S3A–S3F) finished.
- Added a reusable laboratory architecture centered on generic `LivingEntity` interactions rather than xenomorph-specific implementations.
- Established clear ownership boundaries for containment, observation, specimen handling, research, and gameplay adapters.
- Repository verification and architecture gates remain green after Stage 3 completion.

### Containment System
- **NEW**: Generic containment infrastructure independent of Containment Pen implementation.
- **NEW**: Scalable Containment Pen supporting arbitrary validated interior volumes (3×3×3 through 9×9×9).
- **NEW**: Interior containment volume established as the single source of truth for containment behavior.
- **NEW**: Containment integrity, breach, and occupancy services with unique authority ownership.
- **IMPROVED**: Containment Pen now acts as a presentation adapter rather than owning containment logic.
- **IMPROVED**: Formed containment shell blocks proxy player interaction to the controller.

### Observation & Specimen Handling
- **NEW**: Read-only Observation Service providing gameplay facts without owning biology.
- **NEW**: Generic Handling Service supporting command-based specimen operations.
- **NEW**: Motion Tracker rebuilt on ObservationService with configurable consumer filtering.
- Removed remaining xenomorph-specific ownership from specimen handling.

### Research Infrastructure
- **NEW**: Research record system with append-only fact storage.
- **NEW**: Generic sample custody infrastructure.
- **NEW**: Research equipment port separating laboratory machines from research ownership.
- **NEW**: Observation Capture Terminal vertical slice demonstrating research adapters.

### Specimen Management
- **NEW**: Containment UI overview page.
- **NEW**: Multi-page laboratory UI framework.
- **NEW**: Entity preview rendering within containment interfaces.
- **NEW**: Laboratory naming support using vanilla Name Tags.
- **NEW**: Cleanse / Incinerate laboratory workflow with confirmation.
- **NEW**: DNA information page and DNA vial workflow infrastructure.
- DNA biology and mutation mechanics remain future Stage 4 content.

### Capture & Admission
- **NEW**: Capture Net for transporting living specimens as portable laboratory subjects.
- Added admission workflow foundations for future specimen admission architecture.
- Capture pipeline now integrates cleanly with laboratory containment systems.

### Gameplay & Presentation
- **NEW**: Dedicated BioCraft creative tab for laboratory items.
- **IMPROVED**: Drone and Queen model registration.
- **IMPROVED**: Temporary laboratory item models and localization.
- **IMPROVED**: Queen and Drone stand↔crawl transition state machine for smoother animation changes.
- **IMPROVED**: Containment interaction and laboratory usability during playtesting.

### Architecture
- Continued enforcing strict layered architecture and Numeric Dependency Encoding (NDE).
- Expanded contract verification across containment, observation, handling, research, and gameplay adapters.
- Maintained repository-wide verification gates throughout Stage 3 implementation.
- Preserved clear ownership boundaries between gameplay adapters and domain services.

### Deferred
- DNA biology, mutation logic, and host-specific differentiation remain Stage 4 content.
- Specimen Pod (stasis machine), Sample Analyzer, laboratory personnel, and Facehugger Remover remain planned future features.
- Stage 5 continues to own rendering polish, sounds, recovered Blockbench assets, and remaining animation refinement.
