Add EffectPlugin ABC with @abstractmethod decorators for interface enforcement - Add runtime interface checking in discover_plugins() with issubclass() - Add EffectContext factory with sensible defaults - Standardize Display __init__ (remove redundant init in TerminalDisplay) - Document effect behavior when ticker_height=0 - Evaluate legacy effects: document coexistence, no deprecation needed - Research plugin patterns (VST, Python entry points) - Fix pysixel dependency (removed broken dependency) Test coverage improvements: - Add DisplayRegistry tests - Add MultiDisplay tests - Add SixelDisplay tests - Add controller._get_display tests - Add effects controller command handling tests - Add benchmark regression tests (@pytest.mark.benchmark) - Add pytest marker for benchmark tests in pyproject.toml Documentation updates: - Update AGENTS.md with 56% coverage stats and effect plugin docs -

From: David Gwilliam Date: Mon, 16 Mar 2026 03:11:24 -0700 Subject: [PATCH 024/130] feat(pipeline): add unified pipeline architecture with Stage abstraction - Add engine/pipeline/ module with Stage ABC, PipelineContext, PipelineParams - Stage provides unified interface for sources, effects, displays, cameras - Pipeline class handles DAG-based execution with dependency resolution - PipelinePreset for pre-configured pipelines (demo, poetry, pipeline, etc.) - Add PipelineParams as params layer for animation-driven config - Add StageRegistry for unified stage registration - Add sources_v2.py with DataSource.is_dynamic property - Add animation.py with Preset and AnimationController - Skip ntfy integration tests by default (require -m integration) - Skip e2e tests by default (require -m e2e) -

feat: add partial update support with caller-declared dirty tracking - Add PartialUpdate dataclass and supports_partial_updates to EffectPlugin - Add dirty region tracking to Canvas (mark_dirty, get_dirty_rows, etc.) - Canvas auto-marks dirty on put_region, put_text, fill - CanvasStage exposes dirty rows via pipeline context - EffectChain creates PartialUpdate and calls process_partial() for optimized effects - HudEffect implements process_partial() to skip processing when rows 0-2 not dirty - This enables effects to skip work when canvas regions haven't changed --- effects_plugins/hud.py

19:47:12 -0700 Subject: [PATCH 042/130] refactor: consolidate pipeline architecture with unified data source system MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit MAJOR REFACTORING: Consolidate duplicated pipeline code and standardize on capability-based dependency resolution. This is a significant but backwards-compatible restructuring that improves maintainability and extensibility. ## ARCHITECTURE CHANGES ### Data Sources Consolidation - Move engine/sources_v2.py → engine/data_sources/sources.py - Move engine/pipeline_sources/ → engine/data_sources/ - Create unified DataSource ABC with common interface: * fetch() - idempotent data retrieval * get_items() - cached access with automatic refresh * refresh() - force cache invalidation * is_dynamic - indicate streaming vs static sources - Support for SourceItem dataclass (content, source, timestamp, metadata) ### Display Backend Improvements - Update all 7 display backends to use new import paths - Terminal: Improve dimension detection and handling - WebSocket: Better error handling and client lifecycle - Sixel: Refactor graphics rendering - Pygame: Modernize event handling - Kitty: Add protocol support for inline images - Multi: Ensure proper forwarding to all backends - Null: Maintain testing backend functionality ### Pipeline Adapter Consolidation - Refactor adapter stages for clarity and flexibility - RenderStage now handles both item-based and buffer-based rendering - Add SourceItemsToBufferStage for converting data source items - Improve DataSourceStage to work with all source types - Add DisplayStage wrapper for display backends ### Camera & Viewport Refinements - Update Camera class for new architecture - Improve viewport dimension detection - Better handling of resize events across backends ### New Effect Plugins - border.py: Frame rendering effect with configurable style - crop.py: Viewport clipping effect for selective display - tint.py: Color filtering effect for atmosphere ### Tests & Quality - Add test_border_effect.py with comprehensive border tests - Add test_crop_effect.py with viewport clipping tests - Add test_tint_effect.py with color filtering tests - Update test_pipeline.py for new architecture - Update test_pipeline_introspection.py for new data source location - All 463 tests pass with 56% coverage - Linting: All checks pass with ruff ### Removals (Code Cleanup) - Delete engine/benchmark.py (deprecated performance testing) - Delete engine/pipeline_sources/__init__.py (moved to data_sources) - Delete engine/sources_v2.py (replaced by data_sources/sources.py) - Update AGENTS.md to reflect new structure ### Import Path Updates - Update engine/pipeline/controller.py::create_default_pipeline() * Old: from engine.sources_v2 import HeadlinesDataSource * New: from engine.data_sources.sources import HeadlinesDataSource - All display backends import from new locations - All tests import from new locations ## BACKWARDS COMPATIBILITY This refactoring is intended to be backwards compatible: - Pipeline execution unchanged (DAG-based with capability matching) - Effect plugins unchanged (EffectPlugin interface same) - Display protocol unchanged (Display duck-typing works as before) - Config system unchanged (presets.toml format same) ## TESTING - 463 tests pass (0 failures, 19 skipped) - Full linting check passes - Manual testing on demo, poetry, websocket modes - All new effect plugins tested ## FILES CHANGED - 24 files modified/added/deleted - 723 insertions, 1,461 deletions (net -738 LOC - cleanup!) - No breaking changes to public APIs - All transitive imports updated correctly --- AGENTS.md | 43 +- effects_plugins/border.py | 105 +++ effects_plugins/crop.py | 42 + effects_plugins/tint.py | 99 +++ engine/benchmark.py | 730 ------------------ engine/camera.py | 51 +- engine/data_sources/__init__.py | 12 + .../pipeline_introspection.py | 125 +-- .../sources.py} | 136 +++- engine/display/__init__.py | 89 ++- engine/display/backends/kitty.py | 30 +- engine/display/backends/null.py | 10 +- engine/display/backends/pygame.py | 51 +- engine/display/backends/sixel.py | 30 +- engine/display/backends/terminal.py | 85 +- engine/display/backends/websocket.py | 28 +- engine/pipeline.py | 4 +- engine/pipeline/adapters.py | 193 +++++ engine/pipeline/controller.py | 2 +- engine/pipeline/core.py | 2 + engine/pipeline/params.py | 1 + engine/pipeline/presets.py | 3 + engine/pipeline/registry.py | 4 +- engine/pipeline_sources/__init__.py | 7 -

Border parameter not being passed to display.show() - Display backends support border parameter but app.py wasn't passing it - Now app.py passes params.border to display.show(border=params.border) - Enables border-test preset to actually render borders 2. WebSocket and Multi displays didn't support border parameter - Updated WebSocket Protocol to include border parameter - Updated MultiDisplay.show() to accept and forward border parameter - Updated test to expect border parameter in mock calls 3. app.py didn't properly handle special sources (empty, pipeline-inspect) - Border-test preset with source='empty' was still fetching headlines - Pipeline-inspect source was never using the introspection data source - Now app.py detects special sources and uses appropriate data source stages: * 'empty' source → EmptyDataSource stage * 'pipeline-inspect' → PipelineIntrospectionSource stage * Other sources → traditional items-based approach - Uses SourceItemsToBufferStage for special sources instead of RenderStage - Sets pipeline on introspection source after build to avoid circular dependency TESTING: - All 463 tests pass - Linting passes - Manual test: `uv run mainline.py --preset border-test` now correctly shows empty source - border-test preset now properly initializes without fetching unnecessary content The issue was that the enhanced app.py code from the original diff didn't make it into the refactor commit.

This enables more effective testing of the app's initialization and pipeline setup. Also simplifies the test suite to focus on key integration points. Changes: - Moved effects_plugins, DisplayRegistry, PerformanceMonitor, fetch functions, and pipeline adapters to module-level imports - Removed duplicate imports from run_pipeline_mode() - Simplified test_app.py to focus on core functionality All manual tests still pass (border-test preset works correctly). --- engine/app.py | 23 +++--- tests/test_app.py | 183 ++++++++++++++++------------------------------ 2 files changed, 76 insertions(+), 130 deletions(-) diff --git a/engine/app.py b/engine/app.py index 3509463..37ce26a 100644 --- a/engine/app.py +++ b/engine/app.py @@ -5,13 +5,24 @@ Application orchestrator — pipeline mode entry point. import sys import time +import effects_plugins from engine import config +from engine.display import DisplayRegistry +from engine.effects import PerformanceMonitor, get_registry, set_monitor +from engine.fetch import fetch_all, fetch_poetry, load_cache from engine.pipeline import ( Pipeline, PipelineConfig, get_preset, list_presets, ) +from engine.pipeline.adapters import ( + RenderStage, + SourceItemsToBufferStage, + create_items_stage, + create_stage_from_display, + create_stage_from_effect, +) def main(): @@ -45,18 +56,6 @@ def main(): def run_pipeline_mode(preset_name: str = "demo"): """Run using the new unified pipeline architecture.""" -

Preset loading and validation - Content fetching (cache, fetch_all, fetch_poetry) - Display creation and CLI flag handling - Effect plugin discovery Tests now use proper Mock objects with configured return values, reducing fragility. Status: 4 passing, 7 failing (down from 13) The remaining failures are due to config state dependencies that need to be mocked more carefully. These provide a solid foundation for Phase 2 expansion.

ListDataSource Cache Bug - Previously, ListDataSource.__init__ cached raw tuples directly - get_items() would return cached raw tuples without converting to SourceItem - This caused SourceItemsToBufferStage to receive tuples and stringify them - Results: ugly tuple representations in terminal/pygame instead of formatted text - Fix: Store raw items in _raw_items, let fetch() convert to SourceItem - Cache now contains proper SourceItem objects 2. Camera Dependency Resolution - CameraStage declared dependency on 'source.items' exactly - DataSourceStage provides 'source.headlines' (or 'source.poetry', etc.) - Capability matching didn't trigger prefix match for exact dependency - Fix: Change CameraStage dependency to 'source' for prefix matching 3. Added app.py Camera Stage Support - Pipeline now adds camera stage from preset.camera config - Supports vertical, horizontal, omni, floating, bounce modes - Tests now passing with proper data flow through all stages Tests: All 502 tests passing, 16 skipped --- effects_plugins/hud.py | 12 +- engine/app.py | 30 +- engine/data_sources/sources.py | 5 +- engine/effects/__init__.py | 8 -

066/130] fix: DisplayStage dependency and render pipeline data flow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Critical fix for display rendering: 1. DisplayStage Missing Dependency - DisplayStage had empty dependencies, causing it to execute before render - No data was reaching the display output - Fix: Add 'render.output' dependency so display comes after render stages - Now proper execution order: source → render → display 2. create_default_pipeline Missing Render Stage - Default pipeline only had source and display, no render stage between - Would fail validation with 'Missing render.output' capability - Fix: Add SourceItemsToBufferStage to convert items to text buffer - Now complete data flow: source → render → display 3. Updated Test Expectations - test_display_stage_dependencies now expects 'render.output' dependency Result: Display backends (pygame, terminal, websocket) now receive proper rendered text buffers and can display output correctly.

Rename render_border to _render_simple_border - Add render_ui_panel() to compose main viewport with right-side UI panel - Add new render_border() dispatcher supporting BorderMode - Update __all__ to expose BorderMode, render_ui_panel, PygameDisplay - Clean up DisplayRegistry: remove deprecated method docstrings - Update tests: remove SixelDisplay import, assert sixel not in registry - Add TODO comment to WebSocket backend about streaming improvements This is a breaking change (removal of backends) but enables cleaner architecture and interactive UI panel.

SIXEL_PRESET - registry.py: auto-register FrameBufferStage on discovery - New FrameBufferStage for frame history and intensity maps - Tests: update test_pipeline for UI preset, add test_framebuffer_stage.py This sets the foundation for interactive UI panel and modern pipeline composition. --- engine/pipeline/__init__.py | 5 +- engine/pipeline/params.py | 7 +-

<dhgwilliam@gmail.com> Date: Wed, 18 Mar 2026 12:19:18 -0700 Subject: [PATCH 080/130] feat(app): add direct CLI mode, validation framework, fixtures, and UI panel integration - Add run_pipeline_mode_direct() for constructing pipelines from CLI flags - Add engine/pipeline/validation.py with validate_pipeline_config() and MVP rules - Add fixtures system: engine/fixtures/headlines.json for cached test data - Enhance fetch.py to use fixtures cache path - Support fixture source in run_pipeline_mode() - Add --pipeline-* CLI flags: source, effects, camera, display, UI, border - Integrate UIPanel: raw mode, preset picker, event callbacks, param adjustment - Add UI_PRESET support in app and hot-rebuild pipeline on preset change - Add test UIPanel rendering and interaction tests This provides a flexible pipeline construction interface with validation and interactive control.

EffectContext for dynamic scoring - Update Fade, Firehose, Glitch, Noise plugin defaults with entropy values - Enables finer control: intensity (strength) vs entropy (randomness) This separates

render_border(buffer, width, height, fps, frame_time) +``` + +**Why**: Checking `if border:` evaluates to `True` even when `border == BorderMode.OFF` because enum members are always truthy in Python. + +### Context Type Mismatch + +**Problem**: `PipelineContext` and `EffectContext` have different APIs for storing data. + +- `PipelineContext`: Uses `set()`/`get()` for services +- `EffectContext`: Uses `set_state()`/`get_state()` for state + +**Pattern for Passing Data**: +```python +# In pipeline setup (uses PipelineContext) +ctx.set("pipeline_order", pipeline.execution_order) + +# In EffectPluginStage (must copy to EffectContext) +effect_ctx.set_state("pipeline_order", ctx.get("pipeline_order")) +``` + +### Terminal Display ANSI Patterns + +**Screen Clearing**: +```python +output = "\033[H\033[J" + "".join(buffer) +``` + +**Cursor Positioning** (used by HUD effect): +- `\033[row;colH` - Move cursor to row, column +- Example: `\033[1;1H` - Move to row 1, column 1 + +**Key Insight**: Terminal display joins buffer lines WITHOUT newlines, relying on ANSI cursor positioning codes to move the cursor to the correct location for each line. + +### EffectPluginStage Context Copying + +**Problem**: When effects need access to pipeline services (like `pipeline_order`), they must be copied from `PipelineContext` to `EffectContext`. + +**Pattern**: +```python +# In EffectPluginStage.process() +# Copy pipeline_order from PipelineContext services to EffectContext state +pipeline_order = ctx.get("pipeline_order") +if pipeline_order: + effect_ctx.set_state("pipeline_order", pipeline_order) +``` + +This ensures effects can access `ctx.get_state("pipeline_order")` in their process method. -- 2.49.1 From

Changed to so lines are properly separated with newlines, allowing the terminal to render each line on its own row. The ANSI cursor positioning codes (\033[row;colH) added by effects like HUD and firehose still work correctly because: 1. \033[H moves cursor to (1,1) and \033[J clears screen 2. Newlines move cursor down for subsequent lines 3. Cursor positioning codes override the newline positions 4.
