- Add get_dimensions() to Display protocol
- Add DataType enum (SOURCE_ITEMS, TEXT_BUFFER, etc.)
- Add inlet_types and outlet_types to Stage
- Add _validate_types() for type checking at build time
- Update tests with proper type annotations
- Convert presets from YAML to TOML format (no external dep)
- Add DEFAULT_PRESET fallback for graceful degradation
- Add validate_preset() for preset validation
- Add validate_signal_path() for circular dependency detection
- Add generate_preset_toml() for skeleton generation
- Use tomllib (Python 3.11+ stdlib)
- Add Sensor base class with value emission
- Add SensorRegistry for discovery
- Add SensorStage adapter for pipeline
- Add MicSensor (self-contained, no external deps)
- Add OscillatorSensor for testing
- Add sensor param bindings to effects
- Add TransformDataSource for filtering/mapping source items
- Add MetricsDataSource for rendering live pipeline metrics as ASCII art
- Fix display stage registration in StageRegistry
- Register sources with both class name and simple name aliases
- Fix DisplayStage.init() to pass reuse parameter
- Simplify create_default_pipeline to use DataSourceStage wrapper
- Set pygame as default display
- Remove old pipeline tasks from mise.toml
- Add tests for new pipeline architecture
- Add beautiful-mermaid library (single-file ASCII renderer)
- Update pipeline_viz to generate mermaid graphs and render with beautiful-mermaid
- Creates dimensional network visualization with arrows connecting nodes
- Animates through effects and highlights active camera mode
- Add --pipeline-diagram flag to generate mermaid diagrams
- Create engine/pipeline.py with PipelineIntrospector
- Outputs flowchart, sequence diagram, and camera state diagram
- Run with: python mainline.py --pipeline-diagram
- Add Camera class with modes: vertical, horizontal, omni, floating
- Refactor scroll.py and demo to use Camera abstraction
- Add vis_offset for horizontal scrolling support
- Add camera_x to EffectContext for effects
- Add pygame window resize handling
- Add HUD effect plugin for demo mode
- Add --demo flag to run demo mode
- Add tests for Camera and vis_offset
- Add HUD effect plugin showing FPS, effect name, intensity bar, pipeline
- Add pygame window resize handling (VIDEORESIZE event)
- Move HUD to end of chain so it renders on top
- Fix monitor stats API (returns dict, not object)
- Add tests/test_hud.py for HUD effect verification
- Fetch real news/poetry content instead of random letters
- Render full ticker zone with scroll, gradients, firehose
- Demo now shows actual effect behavior on real content
- Add --demo flag that runs effect showcase with pygame display
- Add HUD effect plugin (effects_plugins/hud.py) that displays:
- FPS and frame time
- Current effect name with intensity bar
- Pipeline order
- Demo mode cycles through noise, fade, glitch, firehose effects
- Ramps intensity 0→1→0 over 5 seconds per effect
- Add renderer.py with parse_ansi(), get_default_font_path(), render_to_pil()
- Update KittyDisplay and SixelDisplay to use shared renderer
- Enhance parse_ansi to handle full ANSI color codes (4-bit, 256-color)
- Update tests to use shared renderer functions
- Fix lint errors and LSP issues in benchmark.py
- Add --hook mode to compare against saved baseline
- Add --baseline flag to save results as baseline
- Add --threshold to configure degradation threshold (default 20%)
- Add benchmark step to pre-push hook in hk.pkl
- Update AGENTS.md with hk documentation links and benchmark runner docs
- Implement pure Python Sixel encoder (no C dependency)
- Add SixelDisplay class to display.py with ANSI parsing
- Update controller._get_display() to handle sixel mode
- Add --display sixel CLI flag
- Add mise run-sixel task
- Update docs with display modes
Add typed dataclasses for tuple returns:
- types.py: HeadlineItem, FetchResult, Block dataclasses with legacy tuple converters
- fetch.py: Add type hints and HeadlineTuple type alias
Add pyright for static type checking:
- Add pyright to dependencies
- Verify type coverage with pyright (0 errors in core modules)
This enables:
- Named types instead of raw tuples (better IDE support, self-documenting)
- Type-safe APIs across modules
- Backward compatibility via to_tuple/from_tuple methods
Note: Lazy imports skipped for render.py - startup impact is minimal.
