Recent Changes Summary (February 2025)

Experiment Designer Iteration (February 2025)

Current Focus: Experiment Designer Redesign (Hashing / Drift / Action Library / Properties / DnD / Save & Export)

Status: In active iteration (not stable)

The experiment designer has been refactored into modular components (registry + library + flow + properties panel). Active iteration now targets validation drift visibility, richer parameter controls, and continued provenance/compilation integrity.

Implemented (baseline):

• Step-first container model (steps hold ordered actions) (stable)
• Drag-and-drop of actions into steps and reordering within steps (stable)
• Conversion utility to DB step/action structures (provenance & execution metadata flattening) (stable)
• Plugin action loading with namespaced IDs (pluginId.actionId) and provenance retention (stable)
• Execution compilation pipeline (deterministic graph + integrity hash) integrated in update mutation (stable)

UI State (updated):

• Compact spacing (h-6/7 inputs) and category coloring
• Dark mode variants applied (will audit accessibility)
• Category color system (may refine semantic tokens; now reused across extracted components)
• Step containers with colored left borders for type (moved into StepFlow)
• Drag overlays + hover states (keyboard reordering & provenance badge a11y still pending)

Interaction Features (present / modularized):

• Multi-level drag & drop (steps + actions) via StepFlow
• Direct action selection for inline parameter editing (now inside PropertiesPanel)
• Action tooltip (plugin/source details; provenance badges present; enrichment still planned)
• Drop zone highlighting
• Pointer sensor activation threshold (mobile/touch review pending)

Plugin Integration (status):

• Registry loads core + study plugin actions (version stored; pin drift resolution still pending; designer now guarantees installed study plugin actions appear once experiment + study resolved)
• Fallback actions present (unchanged)
• Param schema → UI field mapping (primitive only; now enhanced for boolean + ranged number)
• Provenance & execution metadata embedded in action instances (server persists) (stable)
• Structured error surfaces for plugin load/validation failures still TODO

Technical Notes (updated):

• Types expanded: provenance, execution descriptors, integrity hashing structures (stable)
• Acceptable performance; profiling after slider & drift logic integration still pending
• Accessibility review pending (keyboard reorder, focus indicators, slider a11y labels)
• Monolith split complete: ActionRegistry.ts, ActionLibrary.tsx, StepFlow.tsx, PropertiesPanel.tsx
• Need unit tests for registry + conversion + compiler + drift serializer; none present

Key Files (current iteration - post modularization):

• ~/components/experiments/designer/BlockDesigner.tsx - Orchestrator (state, validation, drift)

• ~/components/experiments/designer/ActionRegistry.ts - Registry (core + plugin + fallback)

• ~/components/experiments/designer/ActionLibrary.tsx - Categorized draggables

• ~/components/experiments/designer/StepFlow.tsx - Sortable steps & actions

• ~/components/experiments/designer/PropertiesPanel.tsx - Parameter & metadata editor Current State Summary: Functional baseline with modular extraction complete. Parameter UI upgraded (boolean → Switch, ranged number → Slider). Hash drift indicator implemented (Validated / Drift / Unvalidated). Still pending: enum grouping polish, keyboard DnD accessibility, version pin drift resolution, structured plugin load error surfaces.

Experiment Designer Redesign Implementation (in progress)

Status Snapshot

Simplified and unified the seed scripts to load all plugins (core and robot) through the same repository sync mechanism.

Seed Script Consolidation:

• Before: 5 separate seed scripts (seed.ts, seed-dev.ts, seed-simple.ts, seed-plugins.ts, seed-core-blocks.ts)
• After: Single seed-dev.ts script with integrated repository sync
• Benefits: Consistent plugin loading, easier maintenance, real repository testing

Core Repository Integration:

• Core blocks now loaded from http://localhost:3000/hristudio-core during development
• Same repository sync logic as robot plugins from https://repo.hristudio.com
• Eliminates hardcoded core blocks - everything comes from repositories
• Local core repository served from public/hristudio-core/ directory

Simplified Setup Process:

docker compose up -d
bun db:push  
bun db:seed  # Single command loads everything

Repository Sync Integration:

• Core system blocks loaded as single plugin with 4 block groups (27 total blocks)
• Robot plugins loaded individually (TurtleBot3 Burger/Waffle, NAO)
• All repositories use same sync validation and error handling
• Proper metadata storage with repository references

Package.json Cleanup:

• Removed db:seed:simple, db:seed:plugins, db:seed:core-blocks, db:seed:full
• Single db:seed command for all seeding needs
• Simplified development workflow with fewer script options

---

• Spec Document: docs/experiment-designer-redesign.md (completed)
• Hashing Model: Implementing (canonical + incremental planned)
• State Store: Planned (Zustand-based)
• Action Library: Pending rebuild (categorization + search + drift markers)
• Step Flow: Existing structure to be replaced with new DnD + keyboard support
• Properties Panel: To adopt dynamic ParameterFieldFactory (Switch / Slider / etc.)
• Validation Layer: Rule set drafting (structural + param + plugin)
• Drift Detection: Planned (design vs last validated hash + plugin signature drift)
• Save / Versioning: Pending (auto-save + manual + conflict detection)

System Theme Enhancements

Background

The overall system theme was too monochromatic with insufficient color personality.

Improvements Made

Color Palette Enhancement

• Primary Colors: More vibrant blue (oklch(0.55 0.08 240)) instead of grayscale
• Background Warmth: Added subtle warm undertones to light mode
• Sidebar Blue Tint: Maintained subtle blue character as requested
• Chart Colors: Proper color progression (blue → teal → green → yellow → orange)

Light Mode:

--primary: oklch(0.55 0.08 240);        /* Vibrant blue */
--background: oklch(0.98 0.005 60);     /* Warm off-white */
--card: oklch(0.995 0.001 60);          /* Subtle layering */
--muted: oklch(0.95 0.008 240);         /* Slight blue tint */

Dark Mode:

--primary: oklch(0.65 0.1 240);         /* Brighter blue */
--background: oklch(0.12 0.008 250);    /* Soft dark with blue undertone */
--card: oklch(0.18 0.008 250);          /* Proper contrast layers */
--muted: oklch(0.22 0.01 250);          /* Subtle blue-gray */

Results

• Much more personality and visual appeal
• Better color hierarchy and element distinction
• Professional appearance maintained
• Excellent accessibility and contrast maintained

Breadcrumb Navigation Fixes

Problems Identified

1. Study-scoped pages linking to wrong routes (missing context)
2. Form breadcrumbs linking to non-existent entities during creation
3. Inconsistent study context across different data tables

Solutions Implemented

Study Context Awareness

• ExperimentsDataTable: Dashboard → Studies → [Study Name] → Experiments
• ParticipantsDataTable: Dashboard → Studies → [Study Name] → Participants
• TrialsDataTable: Dashboard → Studies → [Study Name] → Trials

Form Breadcrumbs Fixed

• ExperimentForm: Uses study context when available, falls back to global
• ParticipantForm: Links to study-scoped participants when in study context
• TrialForm: Links to study-scoped trials when available

Smart Link Logic

• ✅ With href: Renders as clickable <BreadcrumbLink>
• ✅ Without href: Renders as non-clickable <BreadcrumbPage>
• ✅ Conditional availability: Only provides href when target exists

---

Technical Debt Cleanup

Block Designer Fixes

1. Nested Block Drag & Drop: Added proper SortableContext for child blocks
2. Collision Detection: Enhanced for better nested block handling
3. Helper Functions: Fixed initialization order (findBlockById, removeBlockFromStructure)
4. Background Colors: Matched page theme properly

Permission System

• Added Administrator Bypass: System admins can now edit any experiment
• Study Access Check: Enhanced to check both study membership and system roles

API Enhancement

• Visual Design Storage: Added visualDesign field to experiments update API
• Database Integration: Proper saving/loading of block designs

Core Block System Implementation (February 2024) (archived)

Complete documentation available in docs/core-blocks-system.md

Repository-Based Core Blocks

Complete overhaul of the experiment designer to use plugin-based architecture for all blocks.

Architecture Change:

• Before: Hardcoded core blocks in BlockRegistry.initializeCoreBlocks()
• After: Repository-based loading from hristudio-core plugin repository
• Benefits: Complete consistency, easier updates, extensible core functionality

Core Repository Structure:

hristudio-core/
├── repository.json           # Repository metadata
├── plugins/
│   ├── index.json           # Plugin index (26 total blocks)
│   ├── events.json          # Event trigger blocks (4 blocks)
│   ├── wizard-actions.json  # Wizard action blocks (6 blocks)
│   ├── control-flow.json    # Control flow blocks (8 blocks)
│   └── observation.json     # Observation blocks (8 blocks)
└── assets/                  # Repository assets

Block Categories Implemented:

Event Triggers (4 blocks)

• when_trial_starts - Trial initialization trigger
• when_participant_speaks - Speech detection with duration threshold
• when_timer_expires - Time-based triggers with custom delays
• when_key_pressed - Wizard keyboard shortcuts (space, enter, numbers)

Wizard Actions (6 blocks)

• wizard_say - Speech with tone guidance (neutral, friendly, encouraging)
