Detailed Status

PREREQ-001: Webpack Caching Fix ✅

• Fixed persistent webpack caching issues preventing code changes from loading
• Added cache: false to dev config, build timestamp canary
• Developers no longer need npm run clean:all after every change

PREREQ-002: React 19 Debug Fixes ✅

• Fixed createRoot memory leaks in ConnectionPopup, HMR, and News Modal
• Established root reuse pattern for React 18/19

PREREQ-003: Canvas Overlay Pattern ✅

• Created 5 reference docs in dev-docs/reference/CANVAS-OVERLAY-*
• Documents coordinate systems, event handling, React patterns
• Based on CommentLayer analysis

PREREQ-004: Highlighting API ✅

• HighlightManager singleton with channel system
• React overlay components (HighlightOverlay, HighlightedNode, HighlightedConnection)
• Fixed MacBook trackpad pinch-zoom displacement bug
• Component boundary infrastructure (skeleton methods for future)

VIEW-000: Foundation & Utils ✅

• traversal.ts - Connection chain tracing
• crossComponent.ts - Component boundary resolution
• categorization.ts - Semantic node grouping
• duplicateDetection.ts - Duplicate node detection
• 26 functions, ~1200 lines of code

VIEW-001: Project Topology Map 🟡

Completed:

• Phase 1: Icons & styling (SVG icons, design tokens)
• Phase 2: Enhanced info (gradients, X-Ray stats, connection counts)
• Bug fixes: Card title wrapping, text contrast, mystery icon, padding, node list

Pending:

• Phase 3: Draggable cards (useDraggable hook ready)
• Phase 4: Sticky notes
• Phase 5: Drilldown navigation

VIEW-002: Component X-Ray ✅

• Full sidebar panel implementation
• Shows usage, interface, structure, subcomponents, external deps, internal state
• Navigation to nodes and components
• Known issue: AI function nodes cause sidebar disappearing bug (workaround: close property editor)

VIEW-003: Trigger Chain Debugger ⚠️

Implemented:

• Phase 1: TriggerChainRecorder infrastructure
• Phase 2: Chain builder utilities
• Phase 3: UI panel with timeline, stats

Known Issues (see KNOWN-ISSUES.md):

• Event deduplication still imperfect
• Filtering may show inaccurate data
• Feature marked experimental

VIEW-005: Data Lineage View ⚠️

Implemented but Disabled:

• Core engine in graphAnalysis/lineage.ts
• UI components (DataLineagePanel, LineagePath, PathSummary)

Why Disabled:

• Event handling/timing issues (panel shows "No node selected")
• Excessive/irrelevant data in results (40+ steps for 3-node connection)
• Needs fundamental algorithm rethink

---

Dependencies

• Phase 2 (React Migration) - Required for React overlay patterns
• Canvas overlay pattern documentation (PREREQ-003)
• Graph analysis utilities (VIEW-000)

---

Notes

What's Working Well

• Foundation utilities are robust and well-documented
• Component X-Ray provides significant value
• Highlighting API infrastructure is solid
• Prerequisites unblocked all development work

What Needs Attention

• VIEW-003 needs stability fixes before production use
• VIEW-005 needs algorithm redesign (not small fixes)
• VIEW-001 has remaining phases to implement

Recommended Next Steps

1. Fix VIEW-003 known issues (improve deduplication)
2. Complete VIEW-001 Phase 3 (draggable cards)
3. Consider if VIEW-005 should be redesigned or removed
4. VIEW-004 (Node Census) would be straightforward to implement
