Throttle streaming DOM upserts more aggressively and process DOM updates in smaller batches to keep the UI responsive while moving/resizing the WebChat dialog.
Move chat message HTML/markdown rendering off the UI thread (including tool result ordering inserts) and ensure only the latest render per DOM key is applied.
…ug logging
- Add keyed DOM update queue (`_keyedDomUpdateLatest` + `_keyedDomUpdateQueue`) to ensure only latest render per DOM key is applied, preventing redundant updates during streaming
- Wrap all `Debug.WriteLine` calls in `[Conditional("DEBUG")]` `DebugLog` method to eliminate debug overhead in release builds
- Move HTML equality checks inside `#if DEBUG` blocks to skip expensive string comparisons in production
…fing, and wipe-in animations - Add template cache (`_templateCache`) and LRU HTML cache (`_htmlLru`) to avoid redundant DOM parsing and equality checks during streaming - Implement queued DOM operations (`enqueueDomOp` + `flushDomOps`) batched via `requestAnimationFrame` to reduce layout thrashing - Add sampled equality diffing (25% sample rate) via `shouldSkipBecauseSame` to skip redundant renders when HTML unchanged
…reservation - Remove unused `stream-update` CSS animations and `addStreamUpdateAnimation` JS function - Remove unused `MAX_CONCURRENT_SCRIPTS` and `_activeScripts` variables from chat-script.js - Add `FlushPendingTextStateForTurn` to ensure throttled text deltas are rendered before tool calls appear in the UI - Fix `ConversationSession` to preserve `ContextFilter` when rebuilding AIBody in special turns and helper methods
… improve token efficiency - Add new `instruction_get` tool that returns detailed operational instructions on-demand for canvas operations, component discovery, scripting workflows, and knowledge base usage - Refactor `CanvasButton` system prompt to be concise and delegate detailed tool usage guidelines to `instruction_get` calls - Remove verbose inline documentation for tool workflows (canvas state reading, component discovery, scripting, knowledge base)
…meter validation - Enhance `instruction_get` tool description to explicitly mention required `topic` argument since some models (MistralAI, OpenAI) don't always respect JSON Schema `required` fields but do follow description text - Add explicit validation for missing/empty required parameters in `ToolJsonSchemaValidator` with actionable error messages prompting retry - Remove redundant null check in `instruction_get` tool body
…adapter discovery - Extract duplicated streaming delta processing (~80 lines) into shared `ProcessStreamingDeltasAsync` helper in `ConversationSession` - Add `GetStreamingAdapter()` to `IAIProvider` interface with caching in `AIProvider` base class, replacing reflection-based discovery - Add `CreateStreamingAdapter()` virtual method for providers to override; update OpenAI, DeepSeek, MistralAI, Anthropic, and OpenRouter - Removed "Clear" button from webchat and replaced with a "Regen" button on debug
## Description This PR improves WebChat stability and streaming performance through several optimizations: - **Streaming Infrastructure**: Extracted shared streaming logic into `ProcessStreamingDeltasAsync` helper method and optimized provider adapter discovery with caching instead of reflection - **Performance Optimizations**: Implemented template caching, LRU diffing, keyed queue processing, and wipe-in animations for faster message rendering - **UI Stability**: Reduced WebChat freezes during streaming and drag/resize operations through aggressive DOM throttling and batched updates - **Tool Improvements**: Added `instruction_get` tool to reduce system prompt size and improved its reliability with explicit parameter validation Mitigates #261. ## Breaking Changes No breaking changes. ## Testing Done - Verified WebChat streaming performance improvements during long AI responses - Tested drag/resize operations during active streaming to confirm UI stability - Validated `instruction_get` tool functionality across different AI providers - Confirmed selection context providers work correctly with the new fallback logic ## Checklist - [x] This PR is focused on a single feature or bug fix - [x] Version in Solution.props was updated, if necessary, and follows semantic versioning - [x] CHANGELOG.md has been updated - [x] PR title follows [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) format - [x] PR description follows [Pull Request Description Template](#pull-request-description-template)
…component messages - Replace "Done :)" completion messages with empty strings in AIListEvaluate, AIListFilter, AITextEvaluate, AITextGenerate, and AITextListGenerate components - Update AsyncComponentBase to only set component message when worker output message is non-empty, preventing accidental message clearing
…utput processing - Add early return in post-solve phase when tasks are still running (_setData == 0) or state is not ready (_state <= 0) - Skip output processing until continuation properly sets _state and _setData - Add debug logging to track skipped post-solve executions
- Add BoundsSerializer for panel size serialization using format "bounds:width,height" - Serialize/deserialize panel background color in componentState.additionalProperties.color using Color serializer - Serialize/deserialize panel size in componentState.additionalProperties.bounds while preserving position in pivot - Register BoundsSerializer in DataTypeRegistry - Update GhJSON documentation to reflect panel color and bounds properties
…event stale callbacks - Add early return when debounceTimeMs is 0, indicating timer has been cancelled/reset - Capture debounceTimeMs along with generation and target state in initial lock - Add double-check validation using captured time value to prevent race conditions - Update debug messages to include time value for better diagnostics
- Replace integer literals with double literals in test calculations for type consistency - Mark ComponentStateManager field as readonly in tests - Rename 'run' variable to 'runInput' to avoid shadowing instance field - Simplify conditional expressions using ternary operators in InputChanged methods - Flatten nested if statements in DeepSeekProvider reasoning_content removal logic
…teManager (#364) ## Description Harden stateful component base behaviors to improve stability/reliability across Grasshopper components. ## Breaking Changes Saved files with components from previous version would require to run again or to replace the component. ## Testing Done All cases tested. ## Checklist - [x] This PR is focused on a single feature or bug fix - [x] Version in Solution.props was updated, if necessary, and follows semantic versioning - [x] CHANGELOG.md has been updated - [x] PR title follows [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) format - [x] PR description follows [Pull Request Description Template](#pull-request-description-template)
