# WP Agentic Writer Sidebar 1:1 Migration Plan

**Source of truth:** `assets/js/sidebar.js`
**Source length:** 12,363 lines
**Scope:** planning/audit document only. No implementation code, no build step, no inferred behavior.

This document exists to make the migration match `sidebar.js` exactly. If this file, `MIGRATION_GUIDE.md`, comments, or memory disagree with `assets/js/sidebar.js`, `assets/js/sidebar.js` wins.

## Non-Negotiable Rules

1. Preserve every behavior from `assets/js/sidebar.js` before extracting or improving anything.
2. Convert `wp.element.createElement(...)` to JSX mechanically only after copying the same source range.
3. Preserve hook order, state names, ref names, default values, dependency arrays, effect cleanups, and callback boundaries.
4. Preserve all `wpAgenticWriter` globals, endpoint paths, request bodies, headers, nonces, stream handling, abort handling, and error formatting.
5. Preserve all Gutenberg APIs: `registerPlugin`, `PluginSidebarMoreMenuItem`, `PluginSidebar`, `Panel`, `TextareaControl`, `TextControl`, `CheckboxControl`, `Button`, `RawHTML`, `dispatch`, `select`, and `wp.data.withSelect`.
6. Preserve all DOM tags, component tags, `className` values, dynamic class branches, `role`, `aria-*`, `title`, `placeholder`, `style`, `dangerouslySetInnerHTML`, button labels, visible text, icons, SVG markup, and conditional render gates.
7. Preserve editor block attribute class mutations, especially `wpaw-diff-added` and `wpaw-diff-removed`; these are migration-critical even though they are not sidebar wrapper classes.
8. Do not rename functions, split files, normalize copy, deduplicate logic, replace SVGs, replace `RawHTML`, or change UX flow during the first migration pass.
9. Extraction is allowed only after a monolithic JSX port can be checked against this document line range by line range.

## File-Level Boundaries

| Lines | Required migration unit |
| --- | --- |
| 1-6 | File header comment. Preserve package context if the migrated file keeps source banner comments. |
| 7-15 | IIFE argument and WordPress dependency destructuring. New module imports may replace destructuring only if every dependency maps 1:1. |
| 16-30 | Debug logger and `isDebug` behavior. |
| 31-35 | `pluginIcon` image element with `wpAgenticWriter.pluginUrl + "/assets/img/icon.svg"`, alt text, and 20px style. |
| 37-12347 | `AgenticWriterSidebar` component. |
| 12349-12352 | `mapSelectToProps`, selecting `core/editor`. |
| 12355-12356 | `ConnectedSidebar = wp.data.withSelect(mapSelectToProps)(AgenticWriterSidebar)`. |
| 12358-12362 | `registerPlugin("wp-agentic-writer", { icon: pluginIcon, render: ConnectedSidebar })`. |
| 12363 | IIFE close with `window.wp`. |

## Migration Method

1. Create the new JSX target as a monolith first.
2. Copy ranges in the same order as the coverage table below.
3. Convert element calls mechanically:
   - tag/component name stays the same
   - prop names stay the same
   - children order stays the same
   - conditional gates stay in the same location
   - spread/rest behavior is not introduced unless already present in the source range
4. After the monolith is complete, compare it against this document:
   - every range is present
   - every function exists
   - every state/ref/effect exists in the same hook order
   - every class in the class inventory exists
   - every endpoint in the endpoint inventory exists
   - every render surface exists with the same branches
5. Only after the monolith is proven equivalent, optional extraction may start. Extraction must move code, not rewrite behavior.
