+| Build output | `dist/sidebar.js` (169 KB) |
+
+---
+
+## Overview
+
+This document outlines the approach for splitting the monolithic `assets/js/src/index.jsx` (11,793 lines) into modular React components, hooks, and utilities while maintaining the existing build pipeline.
+
+### Key Principle
+
+> The build pipeline (`scripts/build.js` → `assets/js/dist/sidebar.js`) **already works correctly**. We are refactoring the source for maintainability, NOT fixing a broken build.
+
+### Important: Two sidebar.js Files
+
+| File | Source of Truth? | Loaded by PHP? |
+|------|------------------|---------------|
+| `assets/js/sidebar.js` | ❌ Legacy (webpack, 438KB) | ❌ No |
+| `assets/js/dist/sidebar.js` | ✅ Current (esbuild, 169KB) | ✅ Yes |
+
+> **Do NOT confuse the two files.** The legacy `sidebar.js` (438KB) is the original monolithic file that was never modularized. The `dist/sidebar.js` (169KB) is the esbuild-compiled output from `src/index.jsx`.
+
+---
+
+## Current State
+
+### Build Pipeline (Working ✅)
+
+```
+assets/js/src/index.jsx
+        │
+        │  esbuild (bundle: true)
+        │  format: "iife"
+        │  globalName: undefined (anonymous IIFE)
+        │
+        ▼
+assets/js/dist/sidebar.js (compiled, served to WordPress) ✅
+```
+
+### Source & Output Files
+
+| Path | Lines/Size | Purpose | Status |
+|------|------------|---------|--------|
+| `src/index.jsx` | 11,793 | React source (to be split) | ✅ Active |
+| `dist/sidebar.js` | 169 KB | Compiled output (loaded by PHP) | ✅ Active |
+| `sidebar.js` | 438 KB | **Legacy file** (NOT loaded) | ⚠️ Archived |
+
+### Build Validation (2026-06-17) ✅
+
+| Check | Result |
+|-------|--------|
+| `npm run build` | ✅ Passes (165.8kb output) |
+| PHP syntax (settings) | ✅ Passes |
+| PHP syntax (provider) | ✅ Passes |
+| PHP syntax (provider manager) | ✅ Passes |
+| PHP syntax (local backend) | ✅ Passes |
+| PHP loads `dist/sidebar.js` | ✅ Confirmed in `class-gutenberg-sidebar.php:217` |
+
+### esbuild Configuration
+
+The `scripts/build.js` uses `bundle: true`, which means:
+- All local imports are resolved automatically
+- No need for separate bundler config
+- Extracted files will compile seamlessly
+

+

+
+## Extraction Strategy
+
+### Phase 1: Extract Utilities (Low Risk)
+
+Begin with pure functions that have no React dependencies:
+
+1. **`formatAiErrorMessage`** (lines 42-136)
+   - Pure function, no side effects
+   - Easy to extract and test
+
+2. **`markdownToHtml`** / **`inlineMarkdownToHtml`** (lines 10015-10270)
+   - Large but isolated
+   - No state dependencies
+
+3. **Block utility functions**
+   - `createBlocksFromSerialized`
+   - `getBlockContentForContext`
+   - `getHeadingContextForBlock`
+
+### Phase 2: Extract Custom Hooks
+
+1. **`useChatHistory`**
+   - Session loading, saving, message persistence
+   - Isolated state management
+
+2. **`useSessionLock`**
+   - Tab locking mechanism
+   - Heartbeat management
+
+3. **`useStreaming`**
+   - SSE parsing
+   - Chunk accumulation
+   - Error handling
+
+### Phase 3: Extract UI Components
+
+1. **Tabs** (Chat, Config, Cost)
+   - Each tab can be its own component
+   - Share state via props or context
+
+2. **WelcomeScreen**
+   - Self-contained, minimal dependencies
+
+3. **Clarification Quiz**
+   - Complex but isolated UI
+
+### Phase 4: Extract Editor Integration
+
+The most complex part - interactions with WordPress block editor:
+- Block mutation observation
+- Input blocking
+- Undo/redo integration
+
+---
+
+## Migration Pattern
+
+### Before (in index.jsx)
+```javascript
+const AgenticWriterSidebar = ({ postId }) => {
+  const formatAiErrorMessage = (error) => { /* ... */ };
+  
+  const sendMessage = async (msg) => { /* ... */ };
+  
+  return <div>...</div>;
+};
+```
+
+### After (modular)
+
+**`src/utils/formatUtils.js`**
+```javascript
+export const formatAiErrorMessage = (error, fallback, settings) => {
+  // ...
+};
+```
+
+**`src/hooks/useChatApi.js`**
+```javascript
+export const useChatApi = () => {
+  const sendMessage = async (msg) => { /* ... */ };
+  return { sendMessage };
+};
+```
+
+**`src/index.jsx`**
+```javascript
+import { formatAiErrorMessage } from './utils/formatUtils';
+import { useChatApi } from './hooks/useChatApi';
+import { ChatTab } from './components/ChatTab';
+
+const AgenticWriterSidebar = ({ postId }) => {
+  const { sendMessage } = useChatApi();
+  
+  return <ChatTab onSend={sendMessage} />;
+};
+```
+
+---
+
+## Verification Checklist
+
+After each extraction:
+
+- [ ] `npm run build` completes without errors
+- [ ] Compiled `sidebar.js` matches expected size (±5%)
+- [ ] Chat functionality works (send message, receive response)
+- [ ] Planning functionality works (generate plan)
+- [ ] Refinement works (refine blocks)
+- [ ] Tab switching works
+- [ ] Session persistence works
+- [ ] No console errors in browser
+
+---
+
+## Rollback Plan
+
+If extraction causes issues:
+
+1. Revert the specific extracted file
+2. Keep extracted utilities (safe to keep)
+3. Re-run `npm run build`
+4. Verify functionality
+
+---
+
+## Next Action
+
+1. **Create `src/utils/` directory**
+2. **Extract `formatAiErrorMessage`** as the first migration
+3. **Verify build and functionality**
+4. **Iterate with next extraction**
+
+---
+
+## Dependencies
+
+| Tool | Status |
+|------|--------|
+| esbuild | ✅ Configured |
+| npm | ✅ Available |
+| WordPress environment | ✅ Local by Flywheel |
+
+---
+
+## Questions to Resolve Before Starting
+
+1. Should extracted components use TypeScript or remain JSX?
+2. Should we add PropTypes for component prop validation?
+3. Should we maintain backward compatibility with `wpAgenticWriter` global?

+# WP Agentic Writer – Fix Summary: Chat & Frontend Build
+
+**Date**: 2026-06-16 (original) / 2026-06-17 (updates)
+**Status**: 🟢 RESOLVED
+
+This document serves as a hands-off record of the debugging steps, root causes, and fixes applied to resolve the "empty chat response" issue and establish a proper frontend build pipeline.
+
+---
+
+## Updates (2026-06-17)
+
+### Additional Backend Improvements
+
+1. **Connection Test Caching** - Already existed in `class-provider-manager.php` (5-min TTL via transients)
+2. **Cache Auto-Clear on Settings Save** - Added to `class-settings-v2.php`
+   - Hooks to `updated_option` action
+   - Clears connection test cache when local backend settings change
+3. **Reasoning Content Parsing** - Added to `class-local-backend-provider.php`
+   - Captures `reasoning_content` from thinking models
+   - Debug logging included
+
+### Build Validation ✅
+
+| Check | Result |
+|-------|--------|
+| `npm run build` | ✅ Passes |
+| PHP syntax (all files) | ✅ Passes |
+| Build output | `dist/sidebar.js` (169 KB) |
+
+### Important: Two sidebar.js Files
+
+| File | Loaded by PHP? |
+|------|----------------|
+| `assets/js/sidebar.js` (438 KB) | ❌ Legacy, NOT loaded |
+| `assets/js/dist/sidebar.js` (169 KB) | ✅ Current, loaded |
+
+---
+
+## Original Fixes (2026-06-16)
+
+---
+
+## 1. Frontend Build Pipeline Established
+
+**Problem**: 
+The PHP plugin explicitly loads `assets/js/dist/sidebar.js`. However, ongoing refactoring work was occurring in `assets/js/src/index.jsx`. Because there was no active build process, changes made in `index.jsx` were not reflecting in the application.
+
+**Solution**:
+*   Created `package.json` with `esbuild` to handle fast JSX compilation.
+*   Added `scripts/build.js` configured specifically for WordPress Gutenberg (using `wp.element.createElement` and `wp.element.Fragment`).
+*   **Critical Fix**: Ensured the esbuild configuration wraps the output in an anonymous IIFE (`format: "iife"`) *without* defining a `globalName: "wp"`. A named global would have caused the compiled script to overwrite WordPress's native `window.wp` object with `undefined`, breaking the editor.
+
+**Usage**:
+*   Run `npm run build` to compile `src/index.jsx` -> `dist/sidebar.js`.
+*   Run `npm run build:watch` during active development.
+
+---
+
+## 2. Backend Fix: PHP Fatal Error on Connection Test
+
+**Problem**: 
+When the local backend provider received an HTTP 4xx/5xx error (e.g., when trying to test a connection to a rate-limited or failing model), the entire REST request crashed, resulting in a 500 server error and breaking the chat flow entirely.
+
+**Root Cause**:
+In `includes/class-local-backend-provider.php` (line 882), a double-quoted string was used for a `sprintf` format:
+`__("API Error (HTTP %1$d): %2$s", "wp-agentic-writer")`
+Because it was double-quoted, PHP attempted to interpolate `$d` and `$s` as variables, resolving them to empty strings. The resulting string `API Error (HTTP %1): %2` caused `sprintf` to throw a fatal `ValueError: Unknown format specifier ")"`.
+
+**Fix**:
+Changed the double quotes to single quotes to prevent PHP variable interpolation, preserving the intended positional specifiers:
+`__('API Error (HTTP %1$d): %2$s', "wp-agentic-writer")`
+*Scanned the rest of the codebase and confirmed this dangerous pattern does not exist anywhere else.*
+
+---
+
+## 3. Backend Fix: Agentic Models Returning "Empty Responses"
+
+**Problem**:
+The user experienced intermittent "empty chat response" errors even when the API connection was successful (HTTP 200). 
+
+**Root Cause**:
+The configured models (e.g., `dough/kr/claude-sonnet-4.5-thinking` and `ag/gemini-3-flash-agent`) are **agentic/tool-calling** models. When fed a large WordPress system prompt asking for plain prose, these models burned all their tokens on internal "reasoning", attempted to emit a function/tool call, failed (`finish_reason: "malformed_function_call"`), and returned **zero text content**.
+Because the streaming buffer received no content, it fell back to non-streaming, which also yielded zero content, triggering a generic "empty response" error.
+
+**Fix**:
+1.  **Better Error Surfacing**: Updated the streaming and fallback logic in `class-local-backend-provider.php` to actively capture the `finish_reason` payload.
+2.  If the provider returns empty content but has a finish reason of `malformed_function_call`, `tool_calls`, or `function_call`, the backend now intercepts this and throws a highly specific, actionable error:
+    > *"The selected model [Model Name] returned no text (finish reason: tool/function call). This usually means an agentic/coding model is being used for prose. Choose a standard chat model (without an -agent or -agentic suffix) in Settings."*
+3.  **Config Alignment**: Used WP-CLI to update the WordPress options table, switching the local backend models from the agentic variants to the standard `gemini/gemini-3-flash-preview` for all prose tasks (`chat`, `writing`, `planning`, etc.).
+
+---
+
+## Summary of Touched Files
+*   `package.json` (New)
+*   `scripts/build.js` (New)
+*   `assets/js/dist/sidebar.js` (Rebuilt)
+*   `includes/class-local-backend-provider.php` (Fixed string interpolation, added `finish_reason` edge-case handling, added error payload parsing).
+
+The chat functionality is now robust, gracefully handles agentic model failures, and the React frontend can be reliably compiled from `index.jsx`.
+
+---
+
+## 4. Next Recommendations
+
+With the frontend build pipeline established and the critical backend crashes resolved, the foundation is stable. Here are the recommended next steps:
+
+1. **Complete the React File Splitting (Refactor Phase 2)** ⚠️ IN PROGRESS
+   * Now that `index.jsx` compiles successfully to `dist/sidebar.js`, the massive 11,000+ line `index.jsx` should be split into modular React components.
+   * **See `FRONTEND-REFACTOR-PHASE2.md` for the detailed modularization plan.**
+   * The new `esbuild` setup natively supports resolving local imports, meaning you can safely extract components into a `src/components/` directory and import them into `index.jsx` without changing the PHP backend.
+   * **Key clarification**: The source is `src/index.jsx`, which compiles to `dist/sidebar.js`. We are NOT creating a new `sidebar.jsx` source file - we are modularizing the existing `index.jsx`.
+
+2. **Optimize `test_connection()` in the Provider Manager** ✅ COMPLETED
+   * Implemented connection test caching using WordPress transients with 5-minute TTL in `class-provider-manager.php`.
+   * Added automatic cache clearing in `class-settings-v2.php` when local backend settings are saved (URL, API key, model changes).
+   * This eliminates redundant connection tests on every chat request, significantly reducing latency.
+
+3. **Handle Reasoning Tokens for Thinking Models** ✅ COMPLETED
+   * Added `reasoning_content` parsing to `chat_stream()` method in `class-local-backend-provider.php`.
+   * The streaming parser now captures `chunk["choices"][0]["delta"]["reasoning_content"]` from thinking models like Claude extended thinking.
+   * Reasoning content is passed through the callback so the frontend can optionally display it in a collapsible section.
+   * Debug logging added to help identify when reasoning chunks are received.

+# 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.

+# WP Agentic Writer Sidebar 1:1 Migration Tasklist
+
+**Source task plan:** `SIDEBAR_1_TO_1_MIGRATION.md`
+**Source of truth:** `assets/js/sidebar.js`
+**Mode:** planning/tasklist only. No implementation code, no build step, no inferred behavior.
+
+Use this tasklist to execute the migration described in `SIDEBAR_1_TO_1_MIGRATION.md`. Every checkbox must be completed against `assets/js/sidebar.js`, not memory.
+
+**Current status:** planning docs are in place and the abandoned React rebuild scaffold has been removed from `assets/js`. No build was run, no enqueue switch was made, and implementation now needs to restart from the migration plan rather than from a preexisting React target.
+
+## Ground Rules
+
+- [x] Confirm `assets/js/sidebar.js` is the current source of truth before starting.
+- [x] Confirm `SIDEBAR_1_TO_1_MIGRATION.md` is open beside `assets/js/sidebar.js`.
+- [x] Do not use `MIGRATION_GUIDE.md` as authority when it differs from `assets/js/sidebar.js`.
+- [x] Do not rename functions during the first migration pass.
+- [x] Do not extract helper files during the first migration pass.
+- [x] Do not change visible text, labels, placeholders, icons, SVG markup, classes, inline styles, aria attributes, roles, or conditional render gates.
+- [x] Do not replace `RawHTML`, markdown logic, stream handling, abort handling, localStorage keys, endpoint paths, request bodies, or Gutenberg APIs.
+- [ ] Keep the first target as a monolithic JSX port.
+
+## Definition of Done for Each Range
+
+- [ ] Source range is copied or represented completely.
+- [ ] `createElement` conversion keeps the same tag/component.
+- [ ] Props are preserved 1:1.
+- [ ] Children order is preserved 1:1.
+- [ ] Conditional gates are preserved in the same branch position.
+- [ ] State/ref/effect ordering is preserved.
+- [ ] Callback boundaries and dependency arrays are preserved.
+- [ ] Inline styles, string literals, titles, placeholders, labels, and SVG strings are preserved.
+- [ ] Any migrated range is checked against the original source lines before moving on.
+
+## Phase 0 - Source Lock and Boundaries
+
+- [x] Verify `sidebar.js` has 12,363 lines.
+- [x] Verify file header and IIFE boundary: lines 1-7 and 12363.
+- [x] Verify dependency destructuring: lines 8-15.
+- [x] Verify debug logger and `pluginIcon`: lines 16-35.
+- [x] Verify `AgenticWriterSidebar` starts at line 38.
+- [x] Verify `AgenticWriterSidebar` closes at line 12347.
+- [x] Verify HOC/plugin boot remains separate: lines 12349-12363.
+- [x] Verify main return starts at line 12307.
+- [x] Record any source drift before implementation. If line numbers changed, regenerate this tasklist from the updated source.
+
+## Phase 1 - Monolith Skeleton

+- [ ] Create the migrated target as one monolithic sidebar component.

+
+## Stop Conditions
+
+- [ ] Stop if `sidebar.js` changes and this tasklist has not been regenerated.
+- [ ] Stop if a migrated range requires guessing.
+- [ ] Stop if a function seems unused but exists in `sidebar.js`.
+- [ ] Stop if a class appears styling-only but exists in `sidebar.js`.
+- [ ] Stop if an endpoint or request body differs from `sidebar.js`.
+- [ ] Stop if hook order would change.

+# MEMANTO Integration Plan — Optional Context Enhancement
+
+**Version:** 1.0
+**Date:** 2026-06-07
+**Status:** Planning
+**Depends on:** MEMANTO_PRICING_STRATEGY.md
+
+---
+
+## Design Principles
+
+1. **MEMANTO is optional.** The plugin's built-in Context Builder (`class-context-builder.php`) remains the default and always works without MEMANTO.
+2. **MEMANTO enhances, never replaces.** MySQL sessions (`wpaw_conversations`) remain the primary session store. MEMANTO runs parallel.
+3. **Zero disruption on failure.** If MEMANTO is unreachable, the plugin falls back to existing behavior with no error shown to the user.
+4. **Server-side only.** All MEMANTO API calls happen in PHP. The frontend (sidebar.js) is unaware of MEMANTO — it just sees richer or leaner context in AI responses.
+5. **User brings own Moorcheh key.** Plugin stores MEMANTO URL + Moorcheh API key in WordPress settings. Never hardcoded.
+
+---
+

+
+### Data Flow: Two Paths
+
+| Path | When | What Happens |
+|---|---|---|
+| **Default (no MEMANTO)** | MEMANTO URL not configured in settings | Context Builder uses MySQL session only. Identical to current behavior. |
+| **MEMANTO active** | MEMANTO URL + Moorcheh key configured and validated | Context Builder queries MEMANTO for relevant memories before building context. After AI response, significant events are stored in MEMANTO. |
+
+---
+
+## Agent Design
+
+### Agent Naming Convention
+
+| Agent ID | Scope | Purpose |
+|---|---|---|
+| `wp-user-{wordpress_user_id}` | Per WordPress user | Cross-post preferences: writing style, tone, audience, language, brand voice |
+| `wp-post-{wordpress_post_id}` | Per post | Article-specific: plan decisions, rejections, research, section progress |
+
+### Memory Types Used
+
+| MEMANTO Type | When Stored | Example |
+|---|---|---|
+| `preference` | User sets/changes post config | "User prefers conversational tone, intermediate audience" |
+| `instruction` | User sends chat message | "Focus on plugin vulnerabilities only" |
+| `decision` | User approves/rejects plan | "Approved 5-section outline for WordPress security" |
+| `artifact` | Plan generated, section written | "Plan: 5 sections covering X, Y, Z" |
+| `context` | Session ends / summarize | "Article at 60% completion, 3 of 5 sections done" |
+| `error` | User corrects AI output | "User rejected generic tips approach, wants specific plugin recommendations" |
+
+### Tags Convention
+
+Tags enable targeted recall. Every memory includes:
+
+| Tag | Example | Purpose |
+|---|---|---|
+| `post:{id}` | `post:42` | Scope recall to specific post |
+| `site:{domain}` | `site:example.com` | Scope to WordPress site |
+| `mode:{mode}` | `mode:planning` | What mode was active |
+| `model:{model}` | `model:deepseek-chat` | Which model was used |
+
+---
+
+## New Files to Create
+
+### `includes/class-memanto-client.php`
+
+PHP client for MEMANTO API v2. Singleton class.
+
+**Public Methods:**
+
+| Method | Description |
+|---|---|
+| `is_configured()` | Returns true if MEMANTO URL + Moorcheh key are set in settings |
+| `is_healthy()` | Calls `/health` endpoint, caches result for 5 minutes |
+| `ensure_agent( $agent_id )` | Creates agent via `POST /api/v2/agents` if not exists |
+| `activate_session( $agent_id )` | `POST /api/v2/agents/{id}/activate`, caches session token in transient |
+| `remember( $agent_id, $content, $type, $tags, $title )` | `POST /api/v2/agents/{id}/remember` |
+| `batch_remember( $agent_id, $memories )` | `POST /api/v2/agents/{id}/batch-remember` |
+| `recall( $agent_id, $query, $type, $limit )` | `POST /api/v2/agents/{id}/recall` |
+| `recall_recent( $agent_id, $limit )` | `POST /api/v2/agents/{id}/recall/recent` |
+| `deactivate_session( $agent_id )` | `POST /api/v2/agents/{id}/deactivate` |
+
+**Internal Mechanics:**
+
+- Session token stored in WP transient: `wpaw_memanto_token_{agent_id}` (6-hour TTL matching MEMANTO JWT)
+- Auto-reactivates on expired token (catches 401, re-activates, retries)
+- All calls use `wp_remote_post` / `wp_remote_get` with 10-second timeout
+- All calls wrapped in try/catch with `wpaw_debug_log` on failure
+- Moorcheh API key passed via `X-API-Key` header or configured in MEMANTO instance (depending on MEMANTO's auth model)
+
+### `includes/class-memanto-context-enhancer.php`
+
+Orchestrates when and what to remember/recall. Hooks into existing Context Service.
+
+**Public Methods:**
+
+| Method | Hook Point | Description |
+|---|---|---|
+| `on_session_start( $session_id, $post_id, $user_id )` | Session creation | Ensures user + post agents exist; recalls previous session state |
+| `on_user_message( $session_id, $content, $post_id )` | After user sends message | Stores instruction-type memory |
+| `on_plan_generated( $post_id, $plan )` | After plan creation | Stores artifact-type memory |
+| `on_plan_approved( $post_id, $plan )` | User approves plan | Stores decision-type memory |
+| `on_plan_rejected( $post_id, $reason )` | User rejects/requests changes | Stores error-type memory with rejection reason |
+| `on_section_written( $post_id, $section_id, $summary )` | After section generation | Stores artifact-type memory |
+| `on_block_refined( $post_id, $block_id, $instruction )` | After refinement | Stores instruction-type memory |
+| `on_config_saved( $post_id, $config )` | Post config updated | Stores preference-type memory to both user and post agents |
+| `on_session_end( $session_id, $post_id )` | Session completed/archived | Summarizes session, stores context-type memory, deactivates session |
+| `recall_for_context( $post_id, $user_id, $current_message )` | Before building context | Returns recalled memories to enrich prompt |
+
+**Recall Strategy (`recall_for_context`):**
+
+1. Recall recent memories from post agent (limit: 10)
+2. Recall semantically relevant memories from post agent (query: user's current message, limit: 5)
+3. Recall user preferences from user agent (query: "writing preferences tone audience", limit: 5)
+4. Deduplicate by content hash
+5. Return structured array of recalled items

+
+## Files to Modify
+
+### `includes/class-settings-v2.php`
+
+Add MEMANTO configuration section:
+
+```
+MEMANTO Context Keeper
+├── Enable MEMANTO integration (checkbox, default: off)
+├── MEMANTO Instance URL (text, e.g., https://abc123.context.wpagentic.dev)
+├── Moorcheh API Key (password, user's own key)
+└── Connection Status (read-only, shows "Connected" / "Not configured" / "Error: ...")
+```
+
+Add a "Test Connection" button that calls MEMANTO `/health` endpoint.
+
+### `includes/class-context-builder.php`
+
+Modify `build_for_task()` method. After line ~52 where `$saved_context` is loaded:
+
+```php
+// Existing: MySQL context
+$saved_context = $context_service->get_context( $session_id, $post_id );
+
+// NEW: MEMANTO enhancement (if configured)
+$memanto_context = array();
+$memanto_client = WP_Agentic_Writer_Memanto_Client::get_instance();
+if ( $memanto_client->is_configured() && $memanto_client->is_healthy() ) {
+    $enhancer = WP_Agentic_Writer_Memanto_Context_Enhancer::get_instance();
+    $memanto_context = $enhancer->recall_for_context(
+        $post_id,
+        get_current_user_id(),
+        $request_params['latestUserMessage'] ?? ''
+    );
+}
+```
+
+Modify `build_working_context()` to include a new section:
+
+```php
+// After existing sections, before "Recent saved conversation excerpts"
+if ( ! empty( $memanto_context ) ) {
+    $memory_lines = $this->format_memanto_memories( $memanto_context );
+    if ( '' !== $memory_lines ) {
+        $sections[] = "PERSISTENT MEMORY (recalled from MEMANTO):\n" . $memory_lines;
+    }
+}
+```
+
+**Key rule:** MEMANTO context is **additive**. It never replaces the existing `BACKEND CONTINUITY CONTEXT` section. It supplements it.
+
+### `includes/class-context-service.php`
+
+Add MEMANTO write-through hooks in key methods:
+
+| Method | Hook Added |
+|---|---|
+| `save_plan()` | `$enhancer->on_plan_generated( $post_id, $plan )` |
+| `update_session_context()` | `$enhancer->on_config_saved()` if config changed |
+| `add_message()` | `$enhancer->on_user_message()` for user-role messages |
+| `clear_context()` | Optionally clear MEMANTO post agent memories |
+
+### `includes/class-gutenberg-sidebar.php`
+
+Add MEMANTO hooks in key handler methods:
+
+| Handler | Hook Added |
+|---|---|
+| `handle_chat_request()` | `$enhancer->on_user_message()` after saving to MySQL |
+| `handle_generate_plan()` | `$enhancer->on_plan_generated()` after successful plan |
+| `handle_execute_article()` | `$enhancer->on_section_written()` per section |
+| `handle_refine_block()` | `$enhancer->on_block_refined()` |
+| `handle_summarize_context()` | Skip AI call if MEMANTO active — return cached recall instead |
+| `handle_detect_intent()` | Skip AI call if MEMANTO active — use regex + MEMANTO context instead |
+
+Add new REST endpoint:
+
+```
+POST /wp-agentic-writer/v1/memanto/status
+→ Returns: { connected: bool, agent_count: int, memory_count: int, last_recall: string }
+```
+
+### `includes/class-autoloader.php`
+
+Register the two new classes:
+- `class-memanto-client.php` → `WP_Agentic_Writer_Memanto_Client`
+- `class-memanto-context-enhancer.php` → `WP_Agentic_Writer_Memanto_Context_Enhancer`
+
+### `assets/js/sidebar.js` (minimal change)
+
+No MEMANTO-specific logic needed. Optional enhancement:
+- Show a small "🧠 Memory active" indicator when MEMANTO is connected
+- Show "memories recalled: N" in the context audit display
+
+---
+
+## Graceful Degradation Strategy
+
+```
+MEMANTO call succeeds?
+├── YES → Merge MEMANTO context into working context
+└── NO
+    ├── MEMANTO not configured → Use MySQL-only context (default behavior)
+    ├── MEMANTO timeout (>10s) → Log warning, use MySQL-only context
+    ├── MEMANTO 401 (token expired) → Re-activate session, retry once, then fallback
+    └── MEMANTO 5xx (server error) → Log error, use MySQL-only context
+```
+
+User **never** sees an error from MEMANTO. The worst case is they get the same experience as users without MEMANTO.
+
+---
+
+## Implementation Phases
+
+### Phase 1: Core Client (Week 1)
+
+**Goal:** MEMANTO client class + settings UI + connection validation
+
+| Task | File | Details |
+|---|---|---|
+| Create Memanto Client | `class-memanto-client.php` | All API methods, session token management, error handling |
+| Create Context Enhancer shell | `class-memanto-context-enhancer.php` | Skeleton with `is_configured()` check on every method |
+| Add settings section | `class-settings-v2.php` | URL field, API key field, enable checkbox, test button |
+| Register in autoloader | `class-autoloader.php` | Add both new classes |
+| Add REST status endpoint | `class-gutenberg-sidebar.php` | `/memanto/status` endpoint |
+
+**Validation:** Admin can configure MEMANTO URL + Moorcheh key, test connection, see "Connected" status. No functional changes to AI features yet.
+
+### Phase 2: Write-Through Memory (Week 2)
+
+**Goal:** Store memories on every meaningful action
+
+| Task | Hook Point | Memory Type |
+|---|---|---|
+| Store on user message | `handle_chat_request()` | `instruction` |
+| Store on plan generated | `handle_generate_plan()` | `artifact` |
+| Store on plan approved | After plan save in frontend | `decision` |
+| Store on plan rejected | Plan revision flow | `error` |
+| Store on section written | `handle_execute_article()` | `artifact` |
+| Store on block refined | `handle_refine_block()` | `instruction` |
+| Store on config saved | `update_session_context()` | `preference` |
+| Store on session end | Session completed/archived | `context` |
+
+**Validation:** Write an article with MEMANTO enabled. Check MEMANTO API (via recall endpoint) that memories were stored. Verify plugin still works perfectly with MEMANTO disabled.
+
+### Phase 3: Context Enrichment (Week 3)
+
+**Goal:** Recall memories to enrich AI prompts
+
+| Task | File | Details |
+|---|---|---|
+| Add `recall_for_context()` | `class-memanto-context-enhancer.php` | 3-recall strategy (recent, semantic, preferences) |
+| Modify `build_for_task()` | `class-context-builder.php` | Merge recalled memories into working context |
+| Add `format_memanto_memories()` | `class-context-builder.php` | Format recalled items as compact prompt text |
+| Skip summarize-context when MEMANTO active | `class-gutenberg-sidebar.php` | Return cached recall instead of AI call |
+| Skip detect-intent when MEMANTO active | `class-gutenberg-sidebar.php` | Use regex + MEMANTO context instead |
+
+**Validation:** Write an article. Mid-session, close the browser. Reopen the post. Verify AI "remembers" context from recalled memories. Compare AI response quality with/without MEMANTO.
+
+### Phase 4: Cross-Session Restore (Week 4)
+
+**Goal:** Seamless experience when returning to a post after days/weeks
+
+| Task | Details |
+|---|---|
+| Session restore on load | When post editor opens, recall recent post memories. Build a "restored session" system message. |
+| Frontend indicator | Show "🧠 Restored from memory" badge in sidebar |
+| User preference carry-over | On new post creation, recall user agent preferences for default post config |
+| Session deactivation | On session end, call MEMANTO deactivate to trigger summary generation |
+
+**Validation:** Create an article. Complete 50%. Wait 1 day. Open the post again. Verify AI picks up where it left off without user re-explaining context.
+
+### Phase 5: Polish & Edge Cases (Week 5)
+
+| Task | Details |
+|---|---|
+| Memory pruning | On session end, summarize verbose raw messages into compact context memories |
+| Connection health UI | Real-time status indicator in plugin sidebar header |
+| Moorcheh limit warning | When approaching 10K vectors, show admin notice with upgrade link |
+| Error logging | Detailed MEMANTO error logging with `wpaw_debug_log` |
+| Settings validation | Validate URL format, API key format, connection test before saving |
+
+---
+
+## Testing Strategy
+
+### Unit Tests
+
+| Test | Description |
+|---|---|
+| `test_memanto_client_not_configured` | Client returns false when settings empty |
+| `test_memanto_client_health_check` | Mock `/health` response, verify caching |
+| `test_memanto_client_remember` | Mock remember API, verify payload structure |
+| `test_memanto_client_recall` | Mock recall API, verify response parsing |
+| `test_memanto_client_session_lifecycle` | Activate → remember → recall → deactivate |
+| `test_enhancer_graceful_fallback` | MEMANTO returns error, context builder still works |
+| `test_context_builder_with_memanto` | Verify MEMANTO context is included in working context |
+| `test_context_builder_without_memanto` | Verify no MEMANTO content when not configured |
+
+### Integration Tests
+
+| Test | Description |
+|---|---|
+| Full article with MEMANTO | Chat → Plan → Write → Refine. Verify memories stored at each step. |
+| Full article without MEMANTO | Same flow. Verify no MEMANTO calls made. Plugin works identically. |
+| MEMANTO goes down mid-session | Start with MEMANTO active. Simulate timeout. Verify graceful fallback. |
+| Cross-session restore | Write 50% of article. Simulate new session. Verify AI context restored. |
+| Multi-site with same MEMANTO | Use same MEMANTO instance across 2 sites. Verify agent isolation. |
+
+### Manual Test Checklist
+
+- [ ] Plugin activates with no MEMANTO settings — works normally
+- [ ] MEMANTO URL set but Moorcheh key empty — shows "not configured"
+- [ ] MEMANTO URL + invalid key — shows "connection error"
+- [ ] MEMANTO URL + valid key — shows "connected"
+- [ ] Write article with MEMANTO on — AI responses include recalled memory
+- [ ] Write article with MEMANTO off — identical to current behavior
+- [ ] Disable MEMANTO mid-session — no errors, fallback to MySQL-only
+- [ ] Re-enable MEMANTO — picks up from where it left off
+- [ ] Check MEMANTO recall endpoint — memories exist for test post
+
+---
+
+## Performance Considerations
+
+| Concern | Mitigation |
+|---|---|
+| MEMANTO recall adds latency to every AI call | Cache recall results in transient (5-min TTL). Only recall when context builder runs. |
+| Session token expires mid-request | Auto-reactivate on 401. Single retry. |
+| Too many memories stored | Batch-remember to reduce HTTP calls. Summarize on session end. |
+| MEMANTO instance overloaded | 10-second timeout on all calls. Graceful fallback. |
+| WordPress transient cache bloat | Use specific key patterns. Clean up on session end. |
+
+---
+
+## Settings UI Specification
+
+### MEMANTO Context Keeper Section
+
+Located in WP Agentic Writer → Settings → MEMANTO tab.

+| **Modified files** | `class-context-builder.php`, `class-context-service.php`, `class-gutenberg-sidebar.php`, `class-settings-v2.php`, `class-autoloader.php` |
+| **Frontend changes** | Minimal: status indicator only |
+| **Fallback behavior** | Full graceful degradation to MySQL-only context |
+| **Implementation time** | 5 weeks (1 week per phase) |
+| **Testing priority** | Phase 2 (write-through) and Phase 3 (recall) are critical paths |
+
