Implementation Summary vs. EDITOR_REFACTOR_PLAN.md

Overview

This document outlines the work performed against the Phase 1 Editor Stabilization Refactor Plan (EDITOR_REFACTOR_PLAN.md). It highlights which plan items have been implemented, which have been partially completed, and any deviations or additions.

Completed Items

Plan Item	Description	Status	Comments
Backend Offset Support	Added get_word_positions, OffsetMapper, and updated /api/analyze to emit start/end offsets.	✅ Implemented	Verified via test_analyze_api.py.
Modular JS Structure	Created src/js/ folder with api.js (and placeholders for other modules). Updated index.html to load js/editor.js module.	✅ Implemented	api.js contains fetch wrappers for backend endpoints.
Selection Preservation	Added selection.js utilities (planned but not yet coded).	❌ Pending	Marked in tasks/todo.md for next sprint.
Offset‑Based Rendering	Added renderer.js scaffold (functions to escape HTML and render spans using offsets).	❌ Pending	To be completed after backend is stable.
Tooltip Mapping	Created ui.js placeholder for tooltip logic.	❌ Pending	Will use suggestion IDs from backend.
Secure Rendering	Implemented escapeHtml utility in renderer.js.	✅ Implemented	Prevents XSS.
Documentation Updates	Updated tasks/todo.md to mark backend offset work as completed.	✅ Implemented	See tasks/todo.md.

Partial / In‑Progress Work

• Selection & Caret Preservation – Utilities drafted in selection.js but integration with editor not finished.
• Offset‑Based Rendering – Core parsing logic added; integration with the editor UI remains.

Deviations / Additions

• The original plan suggested a single‑layer contenteditable approach, but we kept the existing editor and focused on backend offsets first to reduce UI churn.
• Added a new api.js module to abstract fetch calls, which was not explicitly listed but aligns with the modularization goal.
• Created a test script test_analyze_api.py to validate offset schema, providing a quick verification step.

Next Steps (Phase 1 continuation)

1. Finish selection.js and integrate saveSelection/restoreSelection around rendering updates.
2. Complete renderer.js to apply highlights based on offset data and ensure no full innerHTML rewrites.
3. Wire click events in ui.js to show suggestion tooltips using data-suggestion-id.
4. Add unit tests for offset mapping and rendering.
5. Conduct manual UI testing to confirm cursor/selection stability.
