+# Technical Design
+
+## Architecture Overview
+
+The GROWI hotkey system manages keyboard shortcuts globally. It uses `tinykeys` (~400 byte) as the key binding engine and a **subscriber component pattern** to execute actions when hotkeys fire.
+
+### Component Diagram
+
+```
+BasicLayout / AdminLayout
+  └─ HotkeysManager (loaded via next/dynamic, ssr: false)
+       ├─ tinykeys(window, bindings) — registers all key bindings
+       └─ renders subscriber components on demand:
+            ├─ EditPage
+            ├─ CreatePage
+            ├─ FocusToGlobalSearch
+            ├─ ShowShortcutsModal
+            ├─ ShowStaffCredit
+            └─ SwitchToMirrorMode
+```
+
+### Key Files
+
+| File | Role |
+|------|------|
+| `src/client/components/Hotkeys/HotkeysManager.tsx` | Core orchestrator — binds all keys via tinykeys, renders subscribers |
+| `src/client/components/Hotkeys/Subscribers/*.tsx` | Individual action handlers rendered when their hotkey fires |
+| `src/components/Layout/BasicLayout.tsx` | Mounts HotkeysManager via `next/dynamic({ ssr: false })` |
+| `src/components/Layout/AdminLayout.tsx` | Mounts HotkeysManager via `next/dynamic({ ssr: false })` |
+
+## Design Decisions
+
+### D1: tinykeys as Binding Engine
+
+**Decision**: Use `tinykeys` (v3) instead of `react-hotkeys` (v2).
+
+**Rationale**:
+- `react-hotkeys` contributes 91 modules to async chunks; `tinykeys` is 1 module (~400 bytes)
+- tinykeys natively supports single keys, modifier combos (`Control+/`), and multi-key sequences (`ArrowUp ArrowUp ...`)
+- No need for custom state machine (`HotkeyStroke`) or detection wrapper (`HotkeysDetector`)
+
+**Trade-off**: tinykeys has no React integration — key binding is done imperatively in a `useEffect` hook rather than declaratively via JSX props. This is acceptable given the simplicity of the binding map.
+
+### D2: Subscriber-Owned Binding Definitions
+
+**Decision**: Each subscriber component exports its own `hotkeyBindings` metadata alongside its React component. `HotkeysManager` imports these definitions and auto-builds the tinykeys binding map — it never hardcodes specific keys or subscriber references.
+
+**Rationale**:
+- True "1 module = 1 hotkey" encapsulation: each subscriber owns its key binding, handler category, and action logic
+- Adding a new hotkey requires creating only one file (the new subscriber); `HotkeysManager` needs no modification
+- Fully satisfies Req 7 AC 2 ("define hotkey without modifying core detection logic")
+- Self-documenting: looking at a subscriber file tells you everything about that hotkey
+
+**Type contract**:
+```typescript
+// Shared type definition in HotkeysManager.tsx or a shared types file
+type HotkeyCategory = 'single' | 'modifier';
+
+type HotkeyBindingDef = {
+  keys: string | string[];   // tinykeys key expression(s)
+  category: HotkeyCategory;  // determines handler wrapper (single = input guard, modifier = no guard)
+};
+
+type HotkeySubscriber = {
+  component: React.ComponentType<{ onDeleteRender: () => void }>;
+  bindings: HotkeyBindingDef;
+};
+```
+
+**Subscriber example**:
+```typescript
+// CreatePage.tsx
+export const hotkeyBindings: HotkeyBindingDef = {
+  keys: 'c',
+  category: 'single',
+};
+
+export const CreatePage = ({ onDeleteRender }: Props): null => { /* ... */ };
+```
+
+```typescript
+// ShowShortcutsModal.tsx
+export const hotkeyBindings: HotkeyBindingDef = {
+  keys: ['Control+/', 'Meta+/'],
+  category: 'modifier',
+};
+```
+
+**HotkeysManager usage**:
+```typescript
+// HotkeysManager.tsx
+import * as createPage from './Subscribers/CreatePage';
+import * as editPage from './Subscribers/EditPage';
+// ... other subscribers
+
+const subscribers: HotkeySubscriber[] = [
+  { component: createPage.CreatePage, bindings: createPage.hotkeyBindings },
+  { component: editPage.EditPage, bindings: editPage.hotkeyBindings },
+  // ...
+];
+
+// In useEffect: iterate subscribers to build tinykeys binding map
+```
+
+**Trade-off**: Slightly more structure than a plain object literal, but the pattern is minimal and each subscriber file is fully self-contained.
+
+### D3: Subscriber Render-on-Fire Pattern
+
+**Decision**: Subscriber components are rendered into the React tree only when their hotkey fires, and self-remove after executing their action.
+
+**Rationale**:
+- Preserves the existing GROWI pattern where hotkey actions need access to React hooks (Jotai atoms, SWR, i18n, routing)
+- Components call `onDeleteRender()` after completing their effect to clean up
+- Uses a monotonically incrementing key ref to avoid React key collisions
+
+### D4: Two Handler Categories
+
+**Decision**: `singleKeyHandler` and `modifierKeyHandler` are separated.
+
+**Rationale**:
+- Single-key shortcuts (`e`, `c`, `/`) must be suppressed when the user is typing in input/textarea/contenteditable elements
+- Modifier-key shortcuts (`Control+/`, `Meta+/`) and multi-key sequences should fire regardless of focus, as they are unlikely to conflict with text entry
+- `isEditableTarget()` check is applied only to single-key handlers
+
+### D5: Client-Only Loading
+
+**Decision**: HotkeysManager is loaded via `next/dynamic({ ssr: false })`.
+
+**Rationale**:
+- Keyboard events are client-only; no SSR rendering is needed
+- Dynamic import keeps hotkey modules out of initial server-rendered chunks
+- Both BasicLayout and AdminLayout follow this pattern
+
+## Implementation Deviations from Requirements
+
+| Requirement | Deviation | Justification |
+|-------------|-----------|---------------|
+| Req 8 AC 2: "export typed interfaces for hotkey definitions" | `HotkeyBindingDef` and `HotkeySubscriber` types are exported for subscriber use but not published as a package API | These types are internal to the Hotkeys module; no external consumers need them |
+
+> **Note (task 5)**: Req 8 AC 1 is now fully satisfied — all 6 subscriber components converted from `.jsx` to `.tsx` with TypeScript `Props` types and named exports.
+> **Note (D2 revision)**: Req 7 AC 2 is now fully satisfied — subscriber-owned binding definitions mean adding a hotkey requires only creating a new subscriber file.
+
+## Key Binding Format (tinykeys)
+
+| Category | Format | Example |
+|----------|--------|---------|
+| Single key | `"key"` | `e`, `c`, `"/"` |
+| Modifier combo | `"Modifier+key"` | `"Control+/"`, `"Meta+/"` |
+| Multi-key sequence | `"key1 key2 key3 ..."` (space-separated) | `"ArrowUp ArrowUp ArrowDown ArrowDown ..."` |
+| Platform modifier | `"$mod+key"` | `"$mod+/"` (Control on Windows/Linux, Meta on macOS) |
+
+> Note: The current implementation uses explicit `Control+/` and `Meta+/` rather than `$mod+/` to match the original behavior.

+# Requirements Document
+
+## Introduction
+
+GROWI currently uses `react-hotkeys` (v2.0.0, 91 modules in async chunk) to manage keyboard shortcuts via a custom subscriber pattern. The library is identified as an optimization target due to its module footprint. This specification covers the migration from `react-hotkeys` to `tinykeys`, a lightweight (~400B) keyboard shortcut library, while preserving all existing hotkey functionality and the subscriber-based architecture.
+
+### Current Architecture Overview
+
+- **HotkeysDetector**: Wraps `react-hotkeys`'s `GlobalHotKeys` to capture key events and convert them to custom key expressions
+- **HotkeyStroke**: State machine model for multi-key sequence detection (e.g., Konami codes)
+- **HotkeysManager**: Orchestrator that maps strokes to subscriber components and manages their lifecycle
+- **Subscribers**: 6 components (CreatePage, EditPage, FocusToGlobalSearch, ShowShortcutsModal, ShowStaffCredit, SwitchToMirrorMode) that self-define hotkeys via static `getHotkeyStrokes()`
+
+### Registered Hotkeys
+
+| Shortcut | Action |
+|----------|--------|
+| `c` | Open page creation modal |
+| `e` | Start page editing |
+| `/` | Focus global search |
+| `Ctrl+/` or `Meta+/` | Open shortcuts help modal |
+| `↑↑↓↓←→←→BA` | Show staff credits (Konami code) |
+| `XXBBAAYYA↓←` | Switch to mirror mode (Konami code) |
+
+## Requirements
+
+### Requirement 1: Replace react-hotkeys Dependency with tinykeys
+
+**Objective:** As a developer, I want to replace `react-hotkeys` with `tinykeys`, so that the application's async chunk module count is reduced and the hotkey system uses a modern, lightweight library.
+
+#### Acceptance Criteria
+
+1. The GROWI application shall use `tinykeys` as the keyboard shortcut library instead of `react-hotkeys`.
+2. When the migration is complete, the `react-hotkeys` package shall be removed from `package.json` dependencies.
+3. The GROWI application shall not increase the total async chunk module count compared to the current `react-hotkeys` implementation.
+
+### Requirement 2: Preserve Single-Key Shortcut Functionality
+
+**Objective:** As a user, I want single-key shortcuts to continue working after the migration, so that my workflow is not disrupted.
+
+#### Acceptance Criteria
+
+1. When the user presses the `c` key (outside an input/textarea/editable element), the Hotkeys system shall open the page creation modal.
+2. When the user presses the `e` key (outside an input/textarea/editable element), the Hotkeys system shall start page editing if the page is editable and no modal is open.
+3. When the user presses the `/` key (outside an input/textarea/editable element), the Hotkeys system shall open the global search modal.
+
+### Requirement 3: Preserve Modifier-Key Shortcut Functionality
+
+**Objective:** As a user, I want modifier-key shortcuts to continue working after the migration, so that keyboard shortcut help remains accessible.
+
+#### Acceptance Criteria
+
+1. When the user presses `Ctrl+/` (or `Meta+/` on macOS), the Hotkeys system shall open the shortcuts help modal.
+
+### Requirement 4: Preserve Multi-Key Sequence (Konami Code) Functionality
+
+**Objective:** As a user, I want multi-key sequences (Konami codes) to continue working after the migration, so that easter egg features remain accessible.
+
+#### Acceptance Criteria
+
+1. When the user enters the key sequence `↑↑↓↓←→←→BA`, the Hotkeys system shall show the staff credits modal.
+2. When the user enters the key sequence `XXBBAAYYA↓←`, the Hotkeys system shall apply the mirror mode CSS class to the document body.
+3. While a multi-key sequence is in progress, the Hotkeys system shall track partial matches and reset if an incorrect key is pressed.
+
+### Requirement 5: Input Element Focus Guard
+
+**Objective:** As a user, I want single-key shortcuts to not fire when I am typing in an input field, so that keyboard shortcuts do not interfere with text entry.
+
+#### Acceptance Criteria
+
+1. While an `<input>`, `<textarea>`, or `contenteditable` element is focused, the Hotkeys system shall suppress single-key shortcuts (e.g., `c`, `e`, `/`).
+2. While an `<input>`, `<textarea>`, or `contenteditable` element is focused, the Hotkeys system shall still allow modifier-key shortcuts (e.g., `Ctrl+/`).
+
+### Requirement 6: Lifecycle Management and Cleanup
+
+**Objective:** As a developer, I want hotkey bindings to be properly registered and cleaned up on component mount/unmount, so that there are no memory leaks or stale handlers.
+
+#### Acceptance Criteria
+
+1. When a layout component (BasicLayout or AdminLayout) mounts, the Hotkeys system shall register all hotkey bindings.
+2. When a layout component unmounts, the Hotkeys system shall unsubscribe all hotkey bindings.
+3. The Hotkeys system shall provide a cleanup mechanism compatible with React's `useEffect` return pattern.
+
+### Requirement 7: Maintain Subscriber Component Architecture
+
+**Objective:** As a developer, I want the subscriber-based architecture to be preserved or appropriately modernized, so that adding or modifying hotkeys remains straightforward.
+
+#### Acceptance Criteria
+
+1. The Hotkeys system shall support a pattern where each hotkey action is defined as an independent unit (component or handler) with its own key binding definition.
+2. When a new hotkey action is added, the developer shall be able to define it without modifying the core hotkey detection logic.
+3. The Hotkeys system shall support dynamic rendering of subscriber components when their associated hotkey fires.
+
+### Requirement 8: TypeScript Migration
+
+**Objective:** As a developer, I want the migrated hotkey system to use TypeScript, so that the code benefits from type safety and better IDE support.
+
+#### Acceptance Criteria
+
+1. The Hotkeys system shall be implemented in TypeScript (`.ts`/`.tsx` files) rather than JavaScript (`.js`/`.jsx`).
+2. The Hotkeys system shall export typed interfaces for hotkey definitions and handler signatures.

+
+> **Note**: Total module count includes both initial (eager) and async (lazy) chunks. Dynamic imports move modules to async chunks without reducing the total, so this metric does NOT reflect lazy-loading improvements. Replaced by ChunkModuleStats KPI below.
+
+### New KPI: ChunkModuleStats (initial / async-only / total)
+
+Measured via `ChunkModuleStatsPlugin` in `next.config.utils.js`. The `initial` count represents modules loaded eagerly on page access — this is the primary reduction target.

+
+> **Note**: Originally reported baseline was 51.5s, but automated measurement on the same machine consistently shows ~31s. The 51.5s figure may reflect cold cache, different system load, or an earlier codebase state.
+
+### Measurement Method
+
+**Automated (Phase 2+)**:
+
+```bash
+# One-command measurement — cleans .next, starts next dev, triggers compilation, outputs results
+./apps/app/bin/measure-chunk-stats.sh        # default port 3099
+./apps/app/bin/measure-chunk-stats.sh 3001   # custom port
+```
+
+Output: `[ChunkModuleStats] initial: N, async-only: N, total: N` + `Compiled /[[...path]] in Xs (N modules)`
+
+**Manual (Phase 1, legacy)**:
+
+```bash
+rm -rf apps/app/.next
+cd apps/app && node_modules/.bin/next dev -p 3000 &
+curl -s http://localhost:3000/
+# Read log output, then: pkill -f "next dev"
+```
+
+**Key details**:
+- `next dev` can be started without MongoDB — it compiles pages on-demand via webpack regardless of database connectivity
+- Compilation is triggered by HTTP access (curl), not by server startup alone (Next.js uses on-demand compilation)
+- `ChunkModuleStatsPlugin` (in `src/utils/next.config.utils.js`) separates modules into initial (eager) vs async-only (lazy) chunks
+- The `initial` count is the primary KPI — modules the browser must load on first page access

+
+### Actual Measurement Results (A/B Bisection)
+
+| Change Group | Modules | Time | vs Baseline |
+|-------------|---------|------|-------------|
+| Baseline (no changes) | 10,066 | ~31s | — |
+| **optimizePackageImports +3 pkgs** | **10,279** | **~31.1s** | **+213 modules, no time change** |
+| locale-utils fix only | ~10,068 | ~31s | +2 modules, no time change |
+| serializer fix only | ~10,066 | ~31s | 0 modules, no time change |
+| axios barrel fix only | ~10,066 | ~31s | 0 modules, no time change |
+| All committed changes (no optimizePkgImports) | 10,068 | ~30.8s | +2 modules, no time change |
+
+> **Key finding**: Static analysis estimates were completely wrong. `optimizePackageImports` INCREASED modules (+213) instead of reducing them. Other changes had zero measurable impact on compilation time.
+
+### Assessment Conclusion
+
+**Phase 1 does not reduce compilation time.** The committed changes (import violation fixes, axios barrel fix) are code quality improvements but have no measurable effect on the dev compilation metric.
+
+**Why Phase 1 had no impact on compilation time**:
+1. **`optimizePackageImports` backfired**: In dev mode, this setting resolves individual sub-module files instead of the barrel, resulting in MORE module entries in webpack's graph. This is the opposite of the expected behavior. **Reverted — not committed.**
+2. **Import violation fixes don't reduce modules meaningfully**: The server modules pulled in by the violations were already being null-loaded (mongoose) or were lightweight (date-fns locale files only).
+3. **Barrel export removal had no measurable effect**: `export * from 'axios'` was unused, so removing it didn't change the module graph.
+4. **Compilation time is dominated by the sheer volume of 10,000+ client-side modules** that are legitimately needed by the `[[...path]]` catch-all page. Incremental import fixes cannot meaningfully reduce this.
+
+### Recommendation: Compilation Time Reduction Requires Architectural Changes
+
+The following approaches can actually reduce compilation time for `[[...path]]`:
+
+1. **Next.js 15 + `bundlePagesRouterDependencies`** — Changes how server dependencies are handled, potentially excluding thousands of modules from client compilation
+2. **Turbopack** — Rust-based bundler with 14x faster cold starts; handles the same 10,000 modules much faster
+3. **Route splitting** — Break `[[...path]]` into smaller routes so each compiles fewer modules on-demand
+
+**Key blockers for Next.js upgrade (Task 8.2)**:
+1. `next-superjson` SWC plugin compatibility — critical blocker
+2. React 19 peer dependency — manageable (Pages Router backward compat)
+3. `I18NextHMRPlugin` — webpack-specific; may need alternative
+
+**Decision**: Phase 1 committed changes are kept as code quality improvements (server/client boundary enforcement, dead code removal). Phase 2 evaluation is needed for actual compilation time reduction.
+
+## Phase 2: Module Graph Analysis and Dynamic Import Optimization (Task 8.1 continued)
+
+### Module Composition Analysis
+
+Client bundle module paths extracted from `.next/static/chunks/` — 6,822 unique modules total.
+
+**Top 10 module-heavy packages in [[...path]] compilation:**
+
+| Package | Modules | % of Total | Source |
+|---------|---------|-----------|--------|
+| lodash-es | 640 | 9.4% | Transitive via mermaid → chevrotain |
+| date-fns | 627 | 9.2% | Direct (barrel imports) + react-datepicker (v2) |
+| highlight.js | 385 | 5.6% | react-syntax-highlighter → CodeBlock |
+| refractor | 279 | 4.1% | react-syntax-highlighter → CodeBlock |
+| core-js | 227 | 3.3% | Next.js polyfills (not controllable via imports) |
+| @codemirror | 127 | 1.9% | Editor components |
+| lodash | 127 | 1.9% | Transitive via express-validator |
+| d3-array | 120 | 1.8% | Transitive via mermaid |
+| react-bootstrap-typeahead | 106 | 1.6% | Search/autocomplete UI |
+| **Top 10 total** | **2,752** | **40%** | |
+
+### Changes Applied
+
+1. **MermaidViewer → `next/dynamic({ ssr: false })`**
+   - Split `import * as mermaid from '~/features/mermaid'` into:
+     - Static: `remarkPlugin` + `sanitizeOption` from `~/features/mermaid/services` (lightweight, no npm mermaid)
+     - Dynamic: `MermaidViewer` via `next/dynamic` (loads mermaid npm + lodash-es + chevrotain on demand)
+   - SSR impact: None — client renderer only (`assert(isClient())`)
+
+2. **CodeBlock → `next/dynamic({ ssr: false })`**
+   - Removed static `import { CodeBlock }` from shared renderer (`src/services/renderer/renderer.tsx`)
+   - Added `DynamicCodeBlock` via `next/dynamic` in client renderer only
+   - SSR impact: Code blocks render without syntax highlighting during SSR (accepted trade-off)
+
+3. **date-fns barrel → subpath imports (12 files)**
+   - Converted all `import { ... } from 'date-fns'` to specific subpath imports
+   - e.g., `import { format } from 'date-fns/format'`
+   - Files: Comment.tsx, ShareLinkForm.tsx, ActivityListItem.tsx, DateRangePicker.tsx, FormattedDistanceDate.jsx, create-custom-axios.ts, activity.ts, user-activation.ts, forgot-password.js, thread-relation.ts, normalize-thread-relation-expired-at.ts, normalize-thread-relation-expired-at.integ.ts
+
+4. **core-js — no action possible**
+   - 227 modules come from Next.js automatic polyfill injection, not application imports
+   - Can only be reduced by `.browserslistrc` (targeting modern browsers) or Next.js 15+ upgrade
+
+### Measurement Results
+
+| Metric | Before | After | Change |
+|--------|--------|-------|--------|
+| Modules | 10,066 | 10,054 | -12 |
+| Compile time (run 1) | ~31s | 26.9s | -4.1s |
+| Compile time (run 2) | ~31s | 26.7s | -4.3s |
+| **Average compile time** | **~31s** | **~26.8s** | **-4.2s (14%)** |
+
+### Analysis
+
+- **Module count decreased only 12**: Dynamic imports still count as modules in the webpack graph, but they're compiled into separate chunks (lazy). The "10,054 modules" includes the lazy chunks' modules in the count.
+- **Compile time decreased ~14%**: The significant improvement suggests webpack's per-module overhead is not uniform — mermaid (with chevrotain parser generator) and react-syntax-highlighter (with highlight.js language definitions) are particularly expensive to compile despite their module count.
+- **date-fns subpath imports**: Contributed to the module count reduction but likely minimal time impact (consistent with Phase 1 findings).

+# Design Document: reduce-modules-loaded
+
+## Overview
+
+**Purpose**: This feature reduces the excessive module count (10,066 modules) compiled for the `[[...path]]` catch-all page in `apps/app`, improving developer experience through faster compilation times and a tighter development feedback loop.
+
+**Users**: GROWI developers working on `apps/app` will benefit from significantly reduced `turbo run dev` compilation times when accessing pages during local development.
+
+**Impact**: Changes the current build configuration, import patterns, and potentially the Next.js version to eliminate unnecessary module loading — particularly server-side modules leaking into the client compilation graph.
+
+### Goals
+- Reduce the `[[...path]]` page module count from 10,066 to a significantly lower number (target: measurable reduction with before/after metrics)
+- Identify and fix server-side module leakage into client bundle
+- Optimize barrel export patterns to prevent full module tree traversal
+- Evaluate and apply Next.js official configuration options for module reduction
+- If beneficial, upgrade Next.js to unlock `bundlePagesRouterDependencies` and `serverExternalPackages`
+
+### Non-Goals
+- Migration from Pages Router to App Router
+- Complete elimination of barrel exports across the entire codebase
+- Turbopack adoption in Phase 1 (deferred to Phase 2b due to webpack config incompatibility; see `research.md` — Turbopack Compatibility section)
+- Performance optimization beyond module count reduction (runtime perf, SSR latency, etc.)
+
+## Architecture
+
+### Existing Architecture Analysis
+
+GROWI `apps/app` uses Next.js 14 with Pages Router, Webpack, and the following relevant configuration:
+
+| Mechanism | Current State | Gap |
+|-----------|--------------|-----|
+| `optimizePackageImports` | 11 `@growi/*` packages | Not expanded to third-party or internal barrel-heavy modules |
+| null-loader (client exclusion) | `mongoose`, `dtrace-provider`, `mathjax-full` | 30+ server-only packages not covered |
+| `next/dynamic` + LazyLoaded pattern | Well-implemented for modal components | Already correct — not a primary contributor |
+| `@next/bundle-analyzer` | Installed, not routinely used | Useful for investigating module composition, but NOT for measuring dev compilation module count |
+| `bundlePagesRouterDependencies` | Not configured | Requires Next.js 15+ |
+| `serverExternalPackages` | Not configured | Requires Next.js 15+ |
+
+**Confirmed Import Violations**:
+1. `src/client/components/RecentActivity/ActivityListItem.tsx` → `~/server/util/locale-utils` (server boundary violation)
+2. `src/client/components/InAppNotification/.../PageBulkExportJobModelNotification.tsx` → `~/models/serializers/.../page-bulk-export-job.ts` → `import mongoose from 'mongoose'` (server module via serializer)
+
+**High-Impact Barrel Exports**:
+- `src/states/ui/editor/index.ts` — 7 wildcard re-exports
+- `src/features/page-tree/index.ts` — 3-level cascading barrels (15+ modules)
+- `src/utils/axios/index.ts` — re-exports entire axios library
+
+### Architecture Pattern & Boundary Map
+
+**Selected pattern**: Phased configuration-driven optimization with incremental structural fixes
+
+The optimization is divided into two phases. Phase 1 operates within the current Next.js 14 + Webpack architecture. Phase 2 evaluates and optionally executes a Next.js version upgrade based on Phase 1 results.

+        B4 --> B7[Resolve next-superjson Blocker]
+    end
+
+    A7 --> B1
+```
+
+**Domain boundaries**:
+- Build Configuration (`next.config.js`) — config-only changes, zero code risk
+- Import Graph (source files) — import path fixes, moderate risk
+- Framework Version (Next.js/React) — major upgrade, high risk
+
+**Existing patterns preserved**: Pages Router, `getServerSideProps`, Jotai/SWR state management, feature-based directory structure
+

+|-------|------------------|-----------------|-------|
+| Build System | Next.js ^14.2.35 (Phase 1) / ^15.x (Phase 2) | Module bundling, compilation | Webpack bundler |
+| Bundler | Webpack 5 (via Next.js) | Module resolution, tree-shaking | Turbopack deferred to Phase 2b |

+### Build Configuration Domain
+
+#### DevCompilationMeasurement
+
+| Field | Detail |
+|-------|--------|
+| Intent | Measure dev compilation module count and time as the primary DX metric; use bundle analyzer as a supplementary investigation tool |
+| Requirements | 1.4, 2.1, 2.2, 2.3, 6.1 |
+
+**Responsibilities & Constraints**
+- Record dev compilation output (`Compiled /[[...path]] in Xs (N modules)`) as the **primary success metric**
+- Use `@next/bundle-analyzer` (`ANALYZE=true`) only as a **supplementary investigation tool** to understand which modules are included and trace import chains — NOT as the success metric
+- Establish baseline before any optimization, then measure after each step
+- Note: dev compilation does NOT tree-shake, so module count reflects the full dependency graph — this is exactly the metric we want to reduce
+
+**Important Distinction**:
+- `next dev` module count = modules webpack processes during on-demand compilation (no tree-shaking) → **this is what makes dev slow**
+- `next build` + ANALYZE = production bundle after tree-shaking → useful for investigation but does NOT reflect dev DX
+
+**Dependencies**
+- External: `@next/bundle-analyzer` — supplementary investigation tool (P1)
+- Inbound: Dev server compilation log — primary metric source (P0)
+
+**Contracts**: —
+
+**Implementation Notes**
+- Primary measurement: `turbo run dev` → access page → read `Compiled /[[...path]] in Xs (N modules)` from log
+- Clean `.next` directory before each measurement for consistent results
+- Supplementary: `ANALYZE=true pnpm run app:build` to inspect module composition when investigating specific leakage paths
+- Repeat measurement 3 times and take median to account for system variability
+
+#### OptimizePackageImportsExpansion
+
+| Field | Detail |
+|-------|--------|
+| Intent | Expand `optimizePackageImports` in `next.config.js` to cover barrel-heavy internal and third-party packages |
+| Requirements | 1.1, 4.3, 4.4 |
+
+**Responsibilities & Constraints**
+- Add packages identified by bundle analysis as barrel-heavy contributors
+- Maintain the existing 11 `@growi/*` entries
+- Identify third-party packages with barrel exports not in the auto-optimized list
+
+**Dependencies**
+- Outbound: `next.config.js` `experimental.optimizePackageImports` — config array (P0)
+- Inbound: BundleAnalysis — identifies which packages need optimization
+
+**Contracts**: Config [x]
+
+##### Configuration Interface
+
+Current configuration to extend:
+
+```typescript
+// next.config.js — experimental.optimizePackageImports
+// Existing entries preserved; new entries added based on bundle analysis
+const optimizePackageImports: string[] = [
+  // Existing @growi/* packages (11)
+  '@growi/core',
+  '@growi/editor',
+  '@growi/pluginkit',
+  '@growi/presentation',
+  '@growi/preset-themes',
+  '@growi/remark-attachment-refs',
+  '@growi/remark-drawio',
+  '@growi/remark-growi-directive',
+  '@growi/remark-lsx',
+  '@growi/slack',
+  '@growi/ui',
+  // Candidates for addition (validate with bundle analysis):
+  // - Third-party packages with barrel exports not in auto-list
+  // - Internal directories if supported by config
+];
+```
+
+**Implementation Notes**
+- Zero-risk config change — does not affect runtime behavior
+- Validate each addition with before/after module count measurement
+- Some packages may already be auto-optimized by Next.js (check against the auto-list in docs)
+
+#### NullLoaderExpansion
+
+| Field | Detail |
+|-------|--------|
+| Intent | Expand null-loader rules in webpack config to exclude additional server-only packages from client bundle |
+| Requirements | 3.1, 3.2 |
+
+**Responsibilities & Constraints**
+- Add null-loader rules for server-only packages confirmed to appear in client bundle by bundle analysis
+- Maintain existing rules for `dtrace-provider`, `mongoose`, `mathjax-full`
+- Only add packages that are actually present in the client bundle (verify with bundle analysis first)
+
+**Dependencies**
+- Outbound: `next.config.js` `webpack()` config — null-loader rules (P0)
+- Inbound: BundleAnalysis — confirms which server packages are in client bundle
+
+**Contracts**: Config [x]
+
+##### Configuration Interface
+
+```typescript
+// next.config.js — webpack config, client-side only (!options.isServer)
+// Existing patterns preserved; candidates added after bundle analysis verification
+const serverPackageExclusions: RegExp[] = [
+  /dtrace-provider/,   // existing
+  /mongoose/,          // existing
+  /mathjax-full/,      // existing
+  // Candidates (add only if confirmed in client bundle):
+  // /@elastic\/elasticsearch/,
+  // /passport/,
+  // /@aws-sdk\//,
+  // /@azure\//,
+  // /@google-cloud\//,
+  // /openai/,
+  // /@opentelemetry\//,
+  // /ldapjs/,
+  // /nodemailer/,
+  // /multer/,
+  // /socket\.io/,
+];
+```
+
+**Implementation Notes**
+- Must verify each package appears in client bundle before adding rule (avoid unnecessary config)
+- null-loader replaces module content with empty module — no runtime impact for correctly excluded packages
+- If a package is accidentally excluded that IS needed on client, it will cause runtime errors — test thoroughly
+
+### Source Code Domain
+
+#### ImportViolationFix
+
+| Field | Detail |
+|-------|--------|
+| Intent | Fix confirmed client-to-server import violations that cause server modules to leak into client bundle |
+| Requirements | 3.1, 3.2, 3.3 |
+
+**Responsibilities & Constraints**
+- Fix the confirmed import violation in `ActivityListItem.tsx` (`~/server/util/locale-utils`)
+- Fix the serializer import in `PageBulkExportJobModelNotification.tsx` (pulls in mongoose)
+- Ensure fixed modules maintain identical functionality
+- Establish a pattern for preventing future violations
+
+**Dependencies**
+- Inbound: BundleAnalysis — identifies import chains causing leakage (P0)
+
+**Contracts**: —
+
+##### Confirmed Violations to Fix
+
+| File | Violation | Fix Strategy |
+|------|-----------|-------------|
+| `src/client/components/RecentActivity/ActivityListItem.tsx` | Imports `getLocale` from `~/server/util/locale-utils` | Extract `getLocale` to a client-safe utility module (the function only needs `date-fns/locale`, no server deps) |
+| `src/client/components/InAppNotification/.../PageBulkExportJobModelNotification.tsx` | Imports serializer that has `import mongoose from 'mongoose'` | Split serializer: server-side `stringifySnapshot` stays in `~/models/`; client-side `parseSnapshot` moves to client-accessible module |
+| `src/stores/in-app-notification.ts` | Imports `~/models/serializers/.../user` | Verify this serializer is clean (confirmed: no mongoose import). Low priority. |
+
+**Implementation Notes**
+- The `getLocale` function itself has no server dependencies — only `date-fns/locale` and `@growi/core/dist/interfaces`. The file's location in `~/server/util/` is misleading; extracting it to `~/utils/` or `~/client/util/` resolves the violation.
+- For the serializer split: `parseSnapshot` is a pure JSON parsing function; `stringifySnapshot` uses mongoose and should remain server-only.
+- Consider adding a lint rule to prevent `src/client/**` or `src/components/**` from importing `src/server/**`.
+
+#### BarrelExportRefactor
+
+| Field | Detail |
+|-------|--------|
+| Intent | Refactor high-impact barrel export files to reduce unnecessary module tree traversal |
+| Requirements | 4.1, 4.2 |
+
+**Responsibilities & Constraints**
+- Refactor after verifying that `optimizePackageImports` expansion does not already resolve the issue
+- Prioritize files with highest module count impact (determined by bundle analysis)
+- Maintain backward compatibility — consumers should not need to change their import paths unless necessary
+
+**Dependencies**
+- Inbound: OptimizePackageImportsExpansion — determines which barrels are already optimized (P1)
+- Inbound: BundleAnalysis — quantifies barrel impact (P1)
+
+**Contracts**: —
+
+##### Target Barrel Files (Priority Order)
+
+| File | Issue | Refactor Strategy |
+|------|-------|-------------------|
+| `src/utils/axios/index.ts` | `export * from 'axios'` re-exports entire library | Replace with specific named exports used by consumers |
+| `src/states/ui/editor/index.ts` | 7 wildcard `export *` | Convert to named re-exports; or verify `optimizePackageImports` handles it |
+| `src/features/page-tree/index.ts` | 3-level cascading barrel (15+ modules) | Flatten to single-level named exports; or consumers import directly from submodules |
+| `src/states/page/index.ts` | 2 wildcard + named exports | Convert to named re-exports if still problematic after config optimization |
+
+**Implementation Notes**
+- Attempt `optimizePackageImports` expansion first — if it handles barrel files for `@growi/*` packages effectively, many of these refactors become unnecessary
+- For `utils/axios/index.ts`, the `export * from 'axios'` pattern is universally problematic; this should be fixed regardless of other optimizations
+- Barrel refactoring may require updating import paths across many files — use IDE refactoring tools and verify with `turbo run lint:typecheck`
+
+### Build Verification Domain
+
+#### LazyLoadVerification
+
+| Field | Detail |
+|-------|--------|
+| Intent | Verify that lazy-loaded components are correctly excluded from initial page compilation |
+| Requirements | 7.1, 7.2, 7.3 |
+
+**Responsibilities & Constraints**
+- Verify the existing `*LazyLoaded` pattern (dynamic.tsx + useLazyLoader) does not contribute to initial module count
+- Confirm `index.ts` files in lazy-loaded component directories only re-export from `dynamic.tsx`
+- Check bundle analysis output for any lazy-loaded component modules in the initial bundle
+
+**Dependencies**
+- Inbound: BundleAnalysis — verifies exclusion from initial bundle (P1)
+
+**Contracts**: —
+
+**Implementation Notes**
+- Gap analysis confirms the LazyLoaded pattern is already well-implemented
+- This component is primarily a verification step, not a fix
+- If any lazy-loaded components are found in the initial bundle, the fix follows the existing `dynamic.tsx` pattern
+
+### Framework Upgrade Domain (Phase 2)
+
+#### NextjsUpgrade
+
+| Field | Detail |
+|-------|--------|
+| Intent | Evaluate and optionally execute Next.js 15 upgrade to unlock `bundlePagesRouterDependencies` and `serverExternalPackages` |
+| Requirements | 5.1, 5.2, 5.3, 5.4, 3.4 |
+
+**Responsibilities & Constraints**
+- Only proceed if Phase 1 results indicate insufficient module reduction
+- Address the `next-superjson` compatibility blocker before upgrading
+- Use the official `@next/codemod` for automated migration
+- Maintain React 18 compatibility with Pages Router (backward compat available in v15)
+
+**Dependencies**
+- External: `next-superjson` — SWC plugin compatibility (P0 blocker)
+- External: React 19 — peer dependency (P0, but backward compat available)
+- External: `@next/codemod` — migration automation (P1)
+
+**Contracts**: Config [x]
+
+##### Configuration Interface (Post-Upgrade)
+
+```typescript
+// next.config.js — New v15 options
+const nextConfig = {
+  // Enable automatic server-side dependency bundling for Pages Router
+  bundlePagesRouterDependencies: true,
+  // Exclude heavy server-only packages from bundling
+  serverExternalPackages: [
+    'mongoose',
+    // Additional packages based on bundle analysis
+  ],
+};

+| `next-superjson` SWC plugin broken in v15 | Critical | Research alternatives: manual superjson in getServerSideProps, or use `superjson` directly without SWC plugin |
+| `I18NextHMRPlugin` (webpack plugin) | Medium | Only affects dev HMR for i18n; can use `--webpack` flag for dev |
+| React 19 peer dependency | Low | Pages Router has React 18 backward compat in v15 |
+| `@next/font` removal | Low | Codemod available; switch to `next/font` |
+
+**Implementation Notes**
+- Run codemod first: `npx @next/codemod@canary upgrade latest`
+- Test with `--webpack` flag to isolate bundler-related issues from framework issues
+- The `bundlePagesRouterDependencies: true` setting is the highest-value v15 feature for this spec — it automatically bundles server-side deps, which combined with `serverExternalPackages` provides fine-grained control
+- Research `next-superjson` alternatives during Phase 1 to have a mitigation ready
+
+## Testing Strategy
+
+### Verification Tests (Module Count — Primary DX Metric)
+- **Primary**: Run `turbo run dev`, access page, record `Compiled /[[...path]] in Xs (N modules)` from log before and after each optimization step
+- **Supplementary**: Run `ANALYZE=true pnpm run app:build` only when investigating specific module composition (e.g., tracing which server modules appear in client bundle)
+- Clean `.next` directory before each measurement; repeat 3 times, take median
+
+### Regression Tests
+- `turbo run lint:typecheck --filter @growi/app` — verify no type errors from import changes
+- `turbo run lint:biome --filter @growi/app` — verify no lint violations
+- `turbo run test --filter @growi/app` — verify all existing tests pass
+- `turbo run build --filter @growi/app` — verify production build succeeds
+- Manual smoke test: access `[[...path]]` page and verify all functionality works (page rendering, editing, navigation, modals)
+
+### Phase 2 Additional Tests
+- All Phase 1 tests
+- `npx @next/codemod@canary upgrade latest --dry` — preview upgrade changes
+- Test superjson serialization: verify `getServerSideProps` data correctly serialized/deserialized for all page routes
+- Test i18n HMR: verify locale changes reflect in dev mode (may degrade if I18NextHMRPlugin is removed)
+
+## Performance & Scalability
+
+**Target Metrics**:
+- **Primary (DX metric)**: Dev compilation module count for `[[...path]]` page (baseline: 10,066 modules)
+- **Secondary (DX metric)**: Dev compilation time for `[[...path]]` page (baseline: 51.5s)
+- **Supplementary (investigation only)**: Production bundle composition via `@next/bundle-analyzer`
+
+> **Important**: The primary metric is the dev compilation log, NOT the production bundle analyzer. Dev compilation does not tree-shake, so the module count directly reflects what makes development slow. Production bundle analysis is useful for tracing import chains but does not represent the dev experience.
+
+**Measurement Protocol**:
+1. Clean `.next` directory (`rm -rf apps/app/.next`)
+2. Run `turbo run dev`
+3. Navigate to `/` or any wiki page path in the browser
+4. Record `Compiled /[[...path]] in Xs (N modules)` from the terminal log
+5. Repeat 3 times, take median value
+6. Record results in a comparison table for each optimization step

+### Server-Only Package Candidates for null-loader
+
+From `apps/app/package.json`, the following packages are server-only and should be excluded from client bundle if they appear there:
+
+| Category | Packages |
+|----------|----------|
+| Database | `mongoose`, `mongodb`, `mongoose-gridfs`, `mongoose-paginate-v2`, `mongoose-unique-validator` |
+| Search | `@elastic/elasticsearch7`, `@elastic/elasticsearch8`, `@elastic/elasticsearch9` |
+| Auth | `passport`, `passport-github2`, `passport-google-oauth20`, `passport-ldapauth`, `passport-saml` |

+
+> Only add null-loader rules for packages confirmed present in the client bundle by bundle analysis.
+
+### Auto-Optimized Packages (No Need to Add to optimizePackageImports)
+
+The following packages are automatically optimized by Next.js and should NOT be added to the config:

+# Gap Analysis: reduce-modules-loaded
+
+## 1. Current State Investigation
+
+### Key Files & Architecture
+
+| Asset | Path | Role |
+|-------|------|------|
+| Next.js config | `apps/app/next.config.js` | Build config with webpack rules, transpilePackages, optimizePackageImports |
+| Catch-all page | `apps/app/src/pages/[[...path]]/index.page.tsx` | Main page route — 10,066 modules on compilation |
+| Server-side props | `apps/app/src/pages/[[...path]]/server-side-props.ts` | getServerSideProps logic |
+| Common props | `apps/app/src/pages/common-props.ts` | Shared server-side props |
+| Transpile utils | `apps/app/src/utils/next.config.utils.js` | Dynamic ESM package discovery for transpilePackages |
+| Package.json | `apps/app/package.json` | 193 dependencies (32+ server-only) |
+
+### Existing Optimization Mechanisms
+
+1. **`optimizePackageImports`** — configured for 11 `@growi/*` packages
+2. **null-loader** — excludes `dtrace-provider`, `mongoose`, `mathjax-full` from client bundle
+3. **`next/dynamic`** — used for 6+ components with `{ ssr: false }`
+4. **LazyLoaded pattern** — `*LazyLoaded` wrapper components use `useLazyLoader` hook with dynamic `import()` — correctly defers actual component loading
+5. **`@next/bundle-analyzer`** — already installed but not routinely used
+
+### Conventions Observed
+
+- **Pages Router** with `getServerSideProps` (not App Router)
+- **next-superjson** for serialization in SSR
+- `pageExtensions: ['page.tsx', 'page.ts', 'page.jsx', 'page.js']`
+- Feature-based organization in `src/features/`
+- State management: Jotai atoms in `src/states/`, SWR hooks in `src/stores/`

+## 2. Requirement-to-Asset Map
+
+### Requirement 1: Next.js Official Configuration Research
+
+| Need | Status | Notes |
+|------|--------|-------|
+| `optimizePackageImports` evaluation | **Partially Exists** | Configured for 11 @growi/* packages; not expanded to cover barrel-heavy third-party deps |
+| `bundlePagesRouterDependencies` evaluation | **Missing** | Not configured; requires Next.js 15+ |
+| `serverExternalPackages` evaluation | **Missing** | Not configured; requires Next.js 15+ |
+| Turbopack evaluation | **Missing** | Currently using Webpack; Turbopack stable in Next.js 15+ |
+| Bundle analysis tooling | **Exists** | `@next/bundle-analyzer` installed; `next experimental-analyze` available in v16.1+ |
+
+### Requirement 2: Module Count Root Cause Analysis
+
+| Need | Status | Notes |
+|------|--------|-------|
+| Bundle analysis tooling | **Exists** | `@next/bundle-analyzer` already in `next.config.js` (ANALYZE env var) |
+| Server-side module identification | **Gap** | No automated mechanism to detect server module leakage |
+| Barrel export impact quantification | **Gap** | No tooling to measure per-barrel module overhead |
+
+### Requirement 3: Server-Side Module Leakage Prevention
+
+| Need | Status | Notes |
+|------|--------|-------|
+| null-loader for mongoose | **Exists** | Already configured |
+| null-loader for other server packages | **Gap — CRITICAL** | 30+ server-only packages NOT excluded (see below) |
+| Client → server import detection | **Gap** | No ESLint rule or build-time check |
+| `serverExternalPackages` | **Gap** | Requires Next.js 15+ |
+
+**Confirmed Leakage Paths:**
+
+1. **`src/client/components/RecentActivity/ActivityListItem.tsx`** → `~/server/util/locale-utils` → pulls in `^/config/i18next.config` (lightweight, but breaks server/client boundary)
+2. **`src/client/components/InAppNotification/ModelNotification/PageBulkExportJobModelNotification.tsx`** → `~/models/serializers/.../page-bulk-export-job.ts` → **`import mongoose from 'mongoose'`** → pulls in entire mongoose + MongoDB driver (but null-loader should catch this on client)
+3. **`src/stores/in-app-notification.ts`** → `~/models/serializers/.../user.ts` (clean — no mongoose import)
+
+**Server-Only Packages Missing from null-loader:**
+
+| Package | Type | Estimated Module Impact |
+|---------|------|----------------------|
+| `@elastic/elasticsearch*` (v7/v8/v9) | Search | High |
+| `passport`, `passport-*` (5 packages) | Auth | Medium |
+| `@aws-sdk/*` | Cloud storage | High |
+| `@azure/*` (3 packages) | Cloud + AI | High |
+| `@google-cloud/storage` | Cloud storage | Medium |
+| `openai`, `@azure/openai` | AI | Medium |
+| `@opentelemetry/*` (8 packages) | Observability | Medium |
+| `ldapjs` | Auth | Low |
+| `nodemailer*` | Email | Low |
+| `multer*` | File upload | Low |
+| `redis`, `connect-redis` | Session | Low |
+| `socket.io` | Real-time | Medium |
+
+> **Note:** Whether these packages actually get pulled into the client bundle depends on whether any client-reachable import chain references them. The null-loader for mongoose suggests this category of leakage has been observed before.
+
+### Requirement 4: Barrel Export and Package Import Optimization
+
+| Need | Status | Notes |
+|------|--------|-------|
+| Expand `optimizePackageImports` | **Gap** | Only 11 @growi/* packages; missing third-party barrel-heavy deps |
+| Eliminate `export *` in states/ | **Gap** | 7+ barrel export files in `src/states/` with `export *` patterns |
+| Eliminate `export *` in features/ | **Gap** | `features/page-tree/index.ts` cascades to 15+ modules |
+| Direct imports instead of barrel | **Gap** | Requires refactoring import paths across codebase |
+
+**High-Impact Barrel Export Files:**
+
+| File | Wildcard Exports | Cascading Depth |
+|------|-----------------|----------------|
+| `src/states/ui/editor/index.ts` | 7 `export *` | 1 level |
+| `src/features/page-tree/index.ts` | 3 `export *` | 3 levels → 15+ modules |
+| `src/features/page-tree/hooks/_inner/index.ts` | 8 `export *` | 1 level |
+| `src/states/page/index.ts` | 2 `export *` + named | 1 level |
+| `src/utils/axios/index.ts` | `export * from 'axios'` | Re-exports entire library |
+
+### Requirement 5: Next.js Version Evaluation and Upgrade
+
+| Need | Status | Notes |
+|------|--------|-------|
+| Current version: Next.js `^14.2.35` | **Exists** | Pages Router architecture |
+| Upgrade to v15 evaluation | **Research Needed** | Breaking changes, React 19 dependency, `bundlePagesRouterDependencies` |
+| Upgrade to v16 evaluation | **Research Needed** | Turbopack default, experimental-analyze tool |
+| Migration effort assessment | **Research Needed** | 30+ page files, custom webpack config, superjson plugin |
+
+### Requirement 6: Compilation Time and Module Count Reduction
+
+| Need | Status | Notes |
+|------|--------|-------|
+| Baseline measurement | **Exists** | 10,066 modules / 51.5s for `[[...path]]` |
+| Before/after metrics framework | **Gap** | No automated benchmarking in CI |
+| Functional regression testing | **Exists** | Vitest test suite, Turbo test pipeline |
+
+### Requirement 7: Lazy Loading and Dynamic Import Verification
+
+| Need | Status | Notes |
+|------|--------|-------|
+| LazyLoaded wrapper pattern | **Exists — Well Designed** | `dynamic.tsx` files use `useLazyLoader` with dynamic `import()` |
+| Index re-export pattern | **Exists — Clean** | `index.ts` files only re-export from `dynamic.tsx`, not the actual component |
+| Verification tooling | **Gap** | No automated check that lazy-loaded components stay out of initial bundle |
+
+**Good News:** The `*LazyLoaded` pattern is already well-implemented:
+```
+index.ts → exports from dynamic.tsx → useLazyLoader(() => import('./ActualComponent'))
+```
+The actual component is only loaded when the trigger condition is met. This is NOT a major contributor to the 10,066 module count.
+
+---
+
+## 3. Implementation Approach Options
+
+### Option A: Configuration-First (No Version Upgrade)
+
+**Approach:** Maximize optimizations within Next.js 14 + Webpack
+
+1. Expand `optimizePackageImports` to cover more barrel-heavy packages
+2. Add null-loader rules for additional server-only packages
+3. Fix confirmed client → server import violations
+4. Refactor critical barrel exports (`states/ui/editor`, `features/page-tree`, `utils/axios`)
+
+**Trade-offs:**
+- ✅ No breaking changes, lowest risk
+- ✅ Immediately measurable impact
+- ✅ Each change is independently verifiable
+- ❌ Limited by Webpack's tree-shaking capabilities
+- ❌ `bundlePagesRouterDependencies` and `serverExternalPackages` unavailable
+- ❌ No Turbopack benefits (automatic import optimization, faster HMR)
+
+### Option B: Next.js 15 Upgrade + Configuration
+
+**Approach:** Upgrade to Next.js 15, then apply v15-specific optimizations
+
+1. Upgrade Next.js 14 → 15 (address breaking changes)
+2. Enable `bundlePagesRouterDependencies` + `serverExternalPackages`
+3. Expand `optimizePackageImports`
+4. Fix client → server import violations
+5. Optionally enable Turbopack for dev
+
+**Trade-offs:**
+- ✅ Unlocks `bundlePagesRouterDependencies` and `serverExternalPackages`
+- ✅ Turbopack available (auto-optimizes imports, 14x faster cold start)
+- ✅ Better tree-shaking in Webpack 5 improvements
+- ❌ React 19 dependency — breaking change risk across all components
+- ❌ `next-superjson` compatibility unknown
+- ❌ Medium-to-high migration effort (30+ page files, custom webpack config)
+- ❌ Risk of regressions across authentication, i18n, etc.
+
+### Option C: Hybrid — Configuration-First, Then Upgrade (Recommended)
+
+**Approach:** Phase 1 optimizes within v14; Phase 2 evaluates and executes upgrade
+
+**Phase 1 (Low Risk, Immediate Impact):**
+1. Run `@next/bundle-analyzer` to establish baseline and identify top contributors
+2. Expand `optimizePackageImports` list
+3. Add null-loader rules for confirmed server-only packages in client bundle
+4. Fix client → server import violations (1 confirmed: `ActivityListItem.tsx`)
+5. Refactor high-impact barrel exports
+6. Measure before/after module count
+
+**Phase 2 (Higher Risk, Longer Term):**
+1. Evaluate Next.js 15/16 upgrade feasibility based on Phase 1 findings
+2. If module count reduction from Phase 1 is insufficient, proceed with upgrade
+3. Enable `bundlePagesRouterDependencies` + `serverExternalPackages`
+4. Evaluate Turbopack adoption for dev mode
+
+**Trade-offs:**
+- ✅ Quick wins first — validates approach before committing to upgrade
+- ✅ Phase 1 findings inform Phase 2 decisions
+- ✅ Incremental risk management
+- ❌ More total effort if upgrade is ultimately needed
+- ❌ Two phases of testing/validation
+

+
+## 4. Effort & Risk Assessment
+
+| Requirement | Effort | Risk | Justification |
+|-------------|--------|------|---------------|
+| Req 1: Config Research | S (1-2 days) | Low | Docs research + local testing |
+| Req 2: Root Cause Analysis | S (1-2 days) | Low | Run bundle analyzer, document findings |
+| Req 3: Server-Side Leakage Fix | M (3-5 days) | Medium | Import chain fixes, null-loader expansion, testing |
+| Req 4: Barrel Export Optimization | M (3-5 days) | Medium | Widespread refactoring of import paths |
+| Req 5: Next.js Upgrade | L-XL (1-3 weeks) | High | React 19, breaking changes, 30+ pages, plugin compat |
+| Req 6: Module Count Reduction | — | — | Outcome of Reqs 1-5 |
+| Req 7: Lazy Loading Verification | S (1 day) | Low | Already well-implemented, needs verification only |
+
+**Overall Effort:** M-L (depending on whether upgrade is pursued)
+**Overall Risk:** Medium (Phase 1) / High (if Next.js upgrade)
+
+---
+
+## 5. Research Items for Design Phase
+
+1. **Next.js 15 breaking changes inventory** — Full compatibility assessment with GROWI's Pages Router, `next-superjson`, custom webpack config
+2. **Turbopack Pages Router support** — Confirm Turbopack works with `getServerSideProps`, `pageExtensions`, custom webpack rules
+3. **null-loader effectiveness validation** — Confirm which server packages actually appear in client bundle (some may already be tree-shaken)
+4. **`bundlePagesRouterDependencies` impact measurement** — Test with GROWI-like setup to measure actual module reduction
+5. **ESLint boundary rule** — Evaluate `eslint-plugin-import` or `@nx/enforce-module-boundaries` for preventing client → server imports
+
+---
+
+## 6. Recommendations for Design Phase
+
+1. **Preferred approach:** Option C (Hybrid) — start with configuration-first optimizations, evaluate upgrade based on results
+2. **First action:** Run `ANALYZE=true pnpm run build` to generate bundle analysis report — this will immediately reveal the top module contributors
+3. **Quick wins to prioritize:**
+   - Expand `optimizePackageImports` (zero-risk config change)
+   - Fix `ActivityListItem.tsx` server import (1 file change)
+   - Verify null-loader coverage for mongoose is effective
+4. **Defer:** Next.js upgrade decision until after Phase 1 metrics are collected

+# Requirements Document
+
+## Introduction
+
+When running `turbo run dev` for `apps/app` and accessing a page, Next.js compiles the `[[...path]]` catch-all route with over 10,000 modules (`Compiled /[[...path]] in 51.5s (10066 modules)`). This is excessive and likely caused by unnecessary server-side modules being pulled into the client bundle, barrel export patterns causing full module tree traversal, and suboptimal tree-shaking. The goal is to investigate root causes, identify effective Next.js configuration options from official documentation, reduce the module count significantly, and improve developer experience (DX) by reducing compilation time. If a Next.js major upgrade is needed to achieve these goals, it should be pursued.
+
+## Requirements
+
+### Requirement 1: Next.js Official Configuration Research
+
+**Objective:** As a developer, I want to research and identify effective Next.js configuration options from official documentation that can reduce the module count and compilation time, so that I can apply proven optimization strategies.
+
+#### Acceptance Criteria
+
+1. The research shall evaluate the following Next.js configuration options for applicability to the GROWI Pages Router architecture:
+   - `optimizePackageImports` — barrel file optimization for packages with hundreds of re-exports (documented to reduce modules by up to 90% for libraries like `@material-ui/icons`: 11,738 → 632 modules)
+   - `bundlePagesRouterDependencies` — automatic server-side dependency bundling for Pages Router (matches App Router default behavior)
+   - `serverExternalPackages` — opt-out specific heavy/native dependencies from server-side bundling to use native Node.js `require`
+   - Turbopack adoption — automatic import optimization without manual `optimizePackageImports` config, with 14x faster cold starts and 28x faster HMR vs Webpack
+2. The research shall document which options are applicable to the current GROWI setup (Pages Router, Next.js 14, Webpack) and which require a version upgrade.
+3. The research shall produce a prioritized list of configuration changes with estimated impact, based on official Next.js benchmarks and the GROWI-specific module analysis.
+4. Where Next.js provides built-in bundle analysis tools (`@next/bundle-analyzer`, `next experimental-analyze`), the research shall evaluate their use for identifying the top module contributors in the `[[...path]]` page.
+
+### Requirement 2: Module Count Root Cause Analysis
+
+**Objective:** As a developer, I want to understand why the `[[...path]]` page loads 10,000+ modules during compilation, so that I can identify actionable optimization targets.
+
+#### Acceptance Criteria
+
+1. When the developer runs a Next.js bundle analysis on the `[[...path]]` page, the GROWI build system shall produce a report identifying the top module contributors by count and size.
+2. The GROWI build system shall identify server-side-only modules (e.g., mongoose, Express models, migration scripts) that are incorrectly included in the client-side compilation of the `[[...path]]` page.
+3. When barrel export files (index.ts with `export *`) are analyzed, the build analysis shall identify which barrel exports cause unnecessary module traversal and quantify the additional modules pulled in by each.
+
+### Requirement 3: Server-Side Module Leakage Prevention
+
+**Objective:** As a developer, I want server-side modules to be excluded from client-side compilation, so that the module count is reduced and compilation time improves.
+
+#### Acceptance Criteria
+
+1. The GROWI application shall ensure that server-side modules (Mongoose models, Express routes, migration scripts, server services) are not included in the client-side module graph of any Next.js page.
+2. When `getServerSideProps` or server-side utility functions import server-only modules, the Next.js build system shall tree-shake those imports from the client bundle.
+3. If a shared module inadvertently imports server-side code, the build system shall detect and report the import chain that causes the leakage.
+4. Where `serverExternalPackages` is available (Next.js 15+), the GROWI build system shall use it to exclude heavy server-only packages (e.g., mongoose, sharp) from server-side bundling.
+
+### Requirement 4: Barrel Export and Package Import Optimization
+
+**Objective:** As a developer, I want to reduce the impact of barrel exports on module resolution, so that importing a single hook or component does not pull in the entire module subtree.
+
+#### Acceptance Criteria
+
+1. When a single export is imported from a state module (e.g., `~/states/page`), the build system shall resolve only the necessary module and its direct dependencies, not the entire barrel export tree.
+2. The GROWI application shall avoid `export * from` patterns in high-traffic import paths (states, stores, features) where tree-shaking is ineffective.
+3. Where `optimizePackageImports` is configured in `next.config.js`, the GROWI build system shall include all internal `@growi/*` packages and high-impact third-party packages that use barrel exports.
+4. The GROWI build system shall expand the existing `optimizePackageImports` list beyond the current 11 `@growi/*` packages to cover additional barrel-heavy dependencies identified in the module analysis.
+
+### Requirement 5: Next.js Version Evaluation and Upgrade
+
+**Objective:** As a developer, I want to evaluate whether upgrading Next.js (from v14 to v15 or later) provides meaningful module optimization improvements, so that I can make an informed upgrade decision.
+
+#### Acceptance Criteria
+
+1. The evaluation shall document which Next.js 15+ features are relevant to reducing module count, specifically:
+   - Turbopack as stable/default bundler (automatic import optimization, no `optimizePackageImports` config needed)
+   - `bundlePagesRouterDependencies` option (automatic server-side dependency bundling for Pages Router)
+   - `serverExternalPackages` (stable rename of `serverComponentsExternalPackages`)
+   - Improved tree-shaking and module resolution
+2. If the Next.js upgrade is determined to be beneficial, the GROWI application shall be upgraded with all breaking changes addressed.
+3. When the upgrade is performed, the GROWI application shall pass all existing tests and build successfully.
+4. If the upgrade is determined to be not beneficial or too risky, the evaluation shall document the reasoning and alternative approaches achievable on the current version.
+
+### Requirement 6: Compilation Time and Module Count Reduction
+
+**Objective:** As a developer, I want the `[[...path]]` page compilation to be significantly faster with fewer modules, so that the development feedback loop is improved.
+
+#### Acceptance Criteria
+
+1. After optimizations, the `[[...path]]` page shall compile with significantly fewer modules than the current 10,066 (target: measurable reduction documented with before/after metrics).
+2. The GROWI application shall maintain full functional correctness after module reduction — no features shall be broken or missing.
+3. While in development mode, the GROWI application shall not show any new runtime errors or warnings introduced by the module optimization changes.
+
+### Requirement 7: Lazy Loading and Dynamic Import Verification
+
+**Objective:** As a developer, I want lazy-loaded components to be truly excluded from the initial compilation, so that they do not contribute to the module count until actually needed.
+
+#### Acceptance Criteria
+
+1. When a component is declared as "lazy loaded" (e.g., `*LazyLoaded` components), the GROWI build system shall not include that component's full dependency tree in the initial page compilation.
+2. The GROWI application shall use `next/dynamic` with `{ ssr: false }` for all heavy modal components that are not needed on initial page render.
+3. Where a lazy-loaded component wrapper (`index.ts`) re-exports the actual component statically, the GROWI application shall restructure the export to prevent static resolution of the full component tree.

+# Research & Design Decisions
+
+## Summary
+- **Feature**: `reduce-modules-loaded`
+- **Discovery Scope**: Complex Integration (build system optimization + potential major framework upgrade)
+- **Key Findings**:
+  - `next-superjson` SWC plugin is broken in Next.js 15 — critical blocker for upgrade
+  - Turbopack (default in v16) does NOT support `webpack()` config — GROWI's null-loader rules and I18NextHMRPlugin are incompatible
+  - `optimizePackageImports` expansion and barrel export refactoring are zero-risk optimizations achievable on current v14
+  - `bundlePagesRouterDependencies` + `serverExternalPackages` require Next.js 15+ but provide significant server-side bundling control
+
+## Research Log
+
+### Next.js 15 Breaking Changes for Pages Router
+- **Context**: Evaluating whether Next.js 15 upgrade is feasible for GROWI's Pages Router architecture
+- **Sources Consulted**: [Next.js v15 Upgrade Guide](https://nextjs.org/docs/app/guides/upgrading/version-15)
+- **Findings**:
+  - React 19 is minimum requirement, but backward compatibility for React 18 is available with Pages Router
+  - `bundlePagesRouterDependencies` is now stable (renamed from `experimental.bundlePagesExternals`)
+  - `serverExternalPackages` is now stable (renamed from `experimental.serverComponentsExternalPackages`)
+  - Async Request APIs change (`cookies`, `headers`, etc.) — App Router only, does NOT affect Pages Router
+  - `@next/font` package removed → must use `next/font` (codemod available)
+  - Caching defaults changed (fetch, Route Handlers) — primarily App Router concern
+- **Implications**:
+  - Pages Router migration is relatively low-impact for the async API changes
+  - The main upgrade value is `bundlePagesRouterDependencies` + `serverExternalPackages`
+  - React 18 backward compat means component migration can be gradual
+
+### next-superjson Compatibility with Next.js 15
+- **Context**: GROWI uses `next-superjson` for SSR serialization in `getServerSideProps`
+- **Sources Consulted**: [next-superjson GitHub](https://github.com/remorses/next-superjson), web search results
+- **Findings**:
+  - `next-superjson-plugin` (SWC-based) is broken in Next.js 15 due to SWC version incompatibility
+  - The `next-superjson` wrapper (used by GROWI — see `withSuperjson()` in `next.config.js`) may have the same issue
+  - GROWI registers custom ObjectId transformer via `superjson.registerCustom`
+  - Alternative: Manual superjson serialization in `getServerSideProps` without the plugin
+- **Implications**:
+  - **Critical blocker** for Next.js 15 upgrade
+  - Must either find a compatible version, migrate to manual superjson usage, or replace with native serialization
+  - This could affect all 30+ page files that use `getServerSideProps`
+
+### Turbopack Compatibility with GROWI
+- **Context**: Turbopack is the default bundler in Next.js 16; evaluating compatibility with GROWI's custom webpack config
+- **Sources Consulted**: [Turbopack API Reference](https://nextjs.org/docs/app/api-reference/turbopack)
+- **Findings**:
+  - Turbopack supports Pages Router and App Router
+  - Turbopack does NOT support `webpack()` configuration in `next.config.js`
+  - Turbopack does NOT support webpack plugins (e.g., `I18NextHMRPlugin`)
+  - Turbopack DOES support webpack loaders via `turbopack.rules` configuration
+  - Automatic import optimization eliminates need for `optimizePackageImports`
+  - Custom `pageExtensions`, `resolveAlias`, `resolveExtensions` are supported
+  - Sass is supported but `sassOptions.functions` is not
+- **GROWI-Specific Blockers**:
+  - `null-loader` rules for mongoose/dtrace-provider/mathjax-full → must be migrated to `turbopack.rules` or alternative exclusion mechanism
+  - `I18NextHMRPlugin` → no Turbopack equivalent; would need alternative HMR approach for i18n
+  - `source-map-loader` in dev mode → must be migrated to Turbopack loader config
+- **Implications**:
+  - Turbopack adoption requires migrating all custom webpack config
+  - The `--webpack` flag allows gradual migration (use Turbopack for dev, Webpack for build)
+  - Long-term Turbopack adoption is desirable but requires significant config migration
+
+### optimizePackageImports Effectiveness
+- **Context**: Evaluating whether expanding `optimizePackageImports` can reduce module count on current v14
+- **Sources Consulted**: [optimizePackageImports docs](https://nextjs.org/docs/pages/api-reference/config/next-config-js/optimizePackageImports), [Vercel blog](https://vercel.com/blog/how-we-optimized-package-imports-in-next-js)
+- **Findings**:
+  - Available since Next.js 13.5 (already usable on v14)
+  - Documented to reduce modules by up to 90% for barrel-heavy packages
+  - Benchmarks: `@material-ui/icons` 11,738 → 632 modules; `lucide-react` 1,583 → 333 modules
+  - Auto-optimized packages include: `lucide-react`, `date-fns`, `lodash-es`, `rxjs`, `@mui/*`, `recharts`, `react-use`, etc.
+  - Works by analyzing barrel files and remapping imports to specific module paths
+  - Handles nested barrel files and `export * from` patterns automatically
+- **Implications**:
+  - **Zero-risk, high-impact optimization** — can be applied immediately on v14
+  - Current GROWI config only covers 11 `@growi/*` packages
+  - Should be expanded to cover internal barrel-heavy directories and any third-party deps not in the auto-list
+
+### Bundle Analysis Tooling
+- **Context**: Need tooling to identify top module contributors and verify optimization impact
+- **Sources Consulted**: [Package Bundling Guide](https://nextjs.org/docs/pages/guides/package-bundling)
+- **Findings**:
+  - `@next/bundle-analyzer` already installed in GROWI; activated via `ANALYZE=true`
+  - `next experimental-analyze` (Turbopack-based) available in v16.1+ — more advanced with import chain tracing
+  - Bundle analyzer generates visual treemap reports for client and server bundles
+- **Implications**:
+  - Can run `ANALYZE=true pnpm run build` immediately to establish baseline
+  - Import chain tracing would help identify server module leakage paths
+  - v16.1 analyzer would be ideal but requires major version upgrade
+
+## Architecture Pattern Evaluation
+
+| Option | Description | Strengths | Risks / Limitations | Notes |
+|--------|-------------|-----------|---------------------|-------|
+| Phase 1: v14 Config Optimization | Expand optimizePackageImports, fix import violations, refactor barrel exports | Zero breaking changes, immediate impact, independently verifiable | Limited by Webpack tree-shaking; no `bundlePagesRouterDependencies` | Recommended first step |
+| Phase 2a: Next.js 15 Upgrade | Upgrade to v15 for `bundlePagesRouterDependencies` + `serverExternalPackages` | Unlocks Pages Router bundling control; stable features | next-superjson broken; React 19 migration | Requires superjson workaround |
+| Phase 2b: Turbopack Adoption (v16) | Upgrade to v16 with Turbopack default | Auto import optimization; 14x faster dev | webpack() config not supported; plugin migration | Longest-term option |
+
+## Design Decisions
+
+### Decision: Phased Approach — Config-First, Then Upgrade
+- **Context**: Need to reduce 10,066 modules with minimal risk while keeping upgrade path open
+- **Alternatives Considered**:
+  1. Direct Next.js 15 upgrade — high risk, next-superjson blocker
+  2. Config-only on v14 — safe but misses v15 bundling features
+  3. Hybrid phased approach — config first, upgrade informed by results
+- **Selected Approach**: Hybrid phased approach (Option C from gap analysis)
+- **Rationale**: Phase 1 provides immediate, low-risk wins. Phase 1 metrics inform whether Phase 2 upgrade is worth the migration cost. next-superjson blocker can be researched during Phase 1 without blocking progress.
+- **Trade-offs**: More total effort if upgrade is needed, but each phase independently delivers value
+- **Follow-up**: Measure module count after Phase 1; research next-superjson alternatives
+
+### Decision: Expand optimizePackageImports Before Refactoring Barrel Exports
+- **Context**: Both approaches reduce barrel export impact, but differ in effort and risk
+- **Alternatives Considered**:
+  1. Refactor all barrel exports to direct imports — high effort, many files affected
+  2. Expand `optimizePackageImports` to handle barrel files automatically — low effort, config-only
+  3. Both — maximum effect
+- **Selected Approach**: Expand `optimizePackageImports` first, measure impact, then refactor remaining barrels if needed
+- **Rationale**: `optimizePackageImports` achieves similar results to barrel refactoring with zero code changes. If the module count drops sufficiently, barrel refactoring may be unnecessary.
+- **Trade-offs**: `optimizePackageImports` may not catch all barrel patterns (e.g., side-effect-heavy modules)
+- **Follow-up**: Verify with bundle analysis which barrels are still problematic after config expansion
+
+### Decision: Fix Server Import Violations Over Expanding null-loader
+- **Context**: Server modules leaking into client bundle via direct imports
+- **Alternatives Considered**:
+  1. Expand null-loader rules for every server package — covers symptoms, not root cause
+  2. Fix import violations at source — eliminates the leakage path
+  3. Both — belt and suspenders
+- **Selected Approach**: Fix import violations at source as primary approach; expand null-loader as safety net for packages that might be transitively included
+- **Rationale**: Fixing imports is more maintainable than maintaining an ever-growing null-loader list. However, null-loader provides defense-in-depth for undiscovered leakage paths.
+- **Trade-offs**: Import fixes require more careful analysis; null-loader is simpler but masks problems
+- **Follow-up**: Use bundle analysis to confirm which server packages actually appear in client bundle
+
+## Risks & Mitigations
+- **Risk**: next-superjson incompatibility blocks Next.js 15 upgrade → **Mitigation**: Research alternatives during Phase 1; manual superjson serialization as fallback
+- **Risk**: Barrel export refactoring causes import breakage across codebase → **Mitigation**: Use `optimizePackageImports` first; refactor incrementally with tests
+- **Risk**: Module count reduction is insufficient from config-only changes → **Mitigation**: Bundle analysis will reveal if server module leakage is the primary cause, guiding whether upgrade is needed
+- **Risk**: I18NextHMRPlugin has no Turbopack equivalent → **Mitigation**: Use `--webpack` flag for dev until alternative is available; Turbopack adoption is Phase 2b

+# Implementation Plan
+
+## Progress Tracking Convention
+
+Analysis tasks (1.2, 3.1, 3.2, 4.1, 5.1, 5.2) may discover a large number of target files. To enable **resumability** and **progress tracking** across interrupted sessions, use the following approach:
+
+### Analysis Ledger File
+
+Create `.kiro/specs/reduce-modules-loaded/analysis-ledger.md` during task 1.2 and maintain it throughout Phase 1. This file serves as the single source of truth for discovered targets and their fix status.
+
+**Structure**:
+```markdown
+# Analysis Ledger
+
+## Measurements
+| Step | Task | Modules | Time | Date |
+|------|------|---------|------|------|
+| Baseline | 1.1 | 10,066 | 51.5s | YYYY-MM-DD |
+| After optimizePackageImports | 2.2 | N | Xs | YYYY-MM-DD |
+| ... | ... | ... | ... | ... |
+
+## Import Violations (Task 3)
+| # | File | Violation | Fix Strategy | Status |
+|---|------|-----------|--------------|--------|
+| 1 | src/client/.../ActivityListItem.tsx | imports ~/server/util/locale-utils | Extract getLocale to client util | pending |
+| 2 | src/client/.../PageBulkExportJobModelNotification.tsx | imports serializer with mongoose | Split parseSnapshot to client module | pending |
+| ... | | | | |
+
+## Server Packages in Client Bundle (Task 4)
+| # | Package | Confirmed in Client Bundle | null-loader Added | Status |
+|---|---------|---------------------------|-------------------|--------|
+| 1 | mongoose | Yes (existing rule) | Yes | done |
+| 2 | @elastic/elasticsearch | TBD | No | pending |
+| ... | | | | |
+
+## Barrel Exports to Refactor (Task 5)
+| # | File | Issue | Still Impactful After optimizePackageImports? | Status |
+|---|------|-------|-----------------------------------------------|--------|
+| 1 | src/utils/axios/index.ts | export * from 'axios' | N/A (always fix) | pending |
+| 2 | src/states/ui/editor/index.ts | 7 wildcard exports | TBD | pending |
+| ... | | | | |
+```
+
+**Rules**:
+- **Create** the ledger during task 1.2 with initial findings
+- **Append** new discoveries as each analysis task runs (tasks 3, 4, 5)
+- **Update Status** to `done` as each individual fix is applied
+- **Read** the ledger at the start of every task to understand current state
+- When resuming after an interruption, the ledger tells you exactly where to pick up
+
+## Phase 1: v14 Optimizations
+
+- [x] 1. Establish baseline dev compilation measurement
+- [x] 1.1 Record baseline module count and compilation time
+  - Baseline: 10,066 modules / 51.5s (reported)
+  - _Requirements: 2.1, 6.1_
+
+- [x] 1.2 (P) Run supplementary bundle analysis and create analysis ledger
+  - Created `analysis-ledger.md` with comprehensive findings
+  - Scanned all client/server import violations, barrel exports, server package candidates
+  - _Requirements: 1.4, 2.1, 2.2, 2.3_
+
+- [x] 2. Expand `optimizePackageImports` configuration — **REJECTED (reverted)**
+- [x] 2.1 Identify barrel-heavy packages to add
+  - Identified: reactstrap (199-line barrel, 124 import sites), react-hook-form (2,602-line barrel, 31 sites), react-markdown (321-line barrel, 6 sites)
+  - _Requirements: 1.1, 1.2, 1.3_
+
+- [x] 2.2 Add candidate packages to the config and measure impact — **REVERTED**
+  - Added reactstrap, react-hook-form, react-markdown to `optimizePackageImports` in `next.config.js`
+  - **Actual measurement: +213 modules (10,066 → 10,279), no compilation time improvement**
+  - `optimizePackageImports` resolves individual module files instead of barrel, resulting in MORE module entries in webpack's dev compilation graph
+  - **Decision: Reverted — config change not included in commit**
+  - _Requirements: 4.3, 4.4, 6.1_
+
+- [x] 3. Fix client-to-server import violations
+- [x] 3.1 Scan for all import violations and update the ledger
+  - Found 2 violations: ActivityListItem.tsx → ~/server/util/locale-utils, PageBulkExportJobModelNotification.tsx → serializer with mongoose
+  - _Requirements: 3.1, 3.3_
+
+- [x] 3.2 (P) Fix all identified import violations
+  - Violation 1: Extracted `getLocale` to `src/utils/locale-utils.ts` (client-safe); updated ActivityListItem.tsx and server module
+  - Violation 2: Created `page-bulk-export-job-client.ts` with `parseSnapshot` + `IPageBulkExportJobSnapshot`; updated client component import
+  - Tests: 18 new tests (15 for locale-utils, 3 for page-bulk-export-job-client) — all pass
+  - _Requirements: 3.1, 3.2, 3.3_
+
+- [x] 3.3 Measure impact of import violation fixes
+  - **Actual measurement: 10,068 modules (vs 10,066 baseline) — +2 modules, no compilation time change (~31s)**
+  - Import violation fixes are architecturally correct (server/client boundary) but do not reduce compilation time
+  - _Requirements: 6.1_
+
+- [x] 4. Expand null-loader rules for server-only packages in client bundle
+- [x] 4.1 Confirm which server packages appear in the client bundle
+  - Comprehensive analysis of all 16 candidate server packages
+  - **Result: No additional server packages are reachable from client code** — all are properly isolated to server-only import paths
+  - openai uses `import type` only in client-reachable interfaces (erased at compile time)
+  - _Requirements: 3.1, 3.2_
+
+- [x] 4.2 Add null-loader rules and measure impact
+  - **No additional null-loader rules needed** — existing rules (mongoose, dtrace-provider, mathjax-full) are sufficient
+  - _Requirements: 3.1, 3.2, 6.1_
+
+- [x] 5. Refactor high-impact barrel exports
+- [x] 5.1 Fix the axios barrel re-export
+  - Removed `export * from 'axios'` — confirmed unused by all 7 consumers (all use default import only)
+  - All 15 existing axios tests pass
+  - _Requirements: 4.1, 4.2_
+
+- [x] 5.2 Evaluate and refactor remaining barrel exports
+  - Evaluated 5 internal barrel files (states/ui/editor, features/page-tree, states/page, etc.)
+  - **Result: No refactoring needed** — internal barrels re-export from small focused files within same domain; `optimizePackageImports` only applies to node_modules packages
+  - _Requirements: 4.1, 4.2_
+
+- [x] 5.3 Measure impact of barrel export refactoring
+  - **Actual measurement: Removing `export * from 'axios'` had no measurable impact on modules or compilation time**
+  - _Requirements: 6.1_
+
+- [x] 6. Verify lazy-loaded components are excluded from initial compilation
+  - Verified all 30 LazyLoaded components follow correct pattern
+  - All index.ts files re-export only from dynamic.tsx
+  - All dynamic.tsx files use useLazyLoader with dynamic import()
+  - No static imports of actual components found
+  - _Requirements: 7.1, 7.2, 7.3_
+
+- [x] 7. Phase 1 final measurement and regression verification
+- [x] 7.1 Record final dev compilation metrics
+  - **Actual measurement (committed changes only, without optimizePackageImports):**
+  - Baseline: 10,066 modules / ~31s
+  - After committed Phase 1 changes: 10,068 modules / ~31s
+  - **Result: No meaningful compilation time reduction from Phase 1 code changes**
+  - Phase 1 changes are valuable as code quality improvements (server/client boundary, unused re-exports) but do not achieve the compilation time reduction goal
+  - _Requirements: 6.1, 6.2, 6.3_
+
+- [x] 7.2 Run full regression test suite
+  - Type checking: Zero errors (tsgo --noEmit)
+  - Biome lint: 1,776 files checked, no errors
+  - Tests: 107 test files pass (1,144 tests); 8 integration test timeouts are pre-existing MongoDB environment issue
+  - Production build: Succeeds
+  - _Requirements: 6.2, 6.3_
+
+## Phase 2: Iterative Module Reduction (Dynamic Import & Import Optimization)
+
+### KPI
+
+- **Primary**: `[ChunkModuleStats] initial` — modules in eager (initial) chunks
+- **Baseline**: initial: 2,704 (before Phase 2 changes)
+- Measured via `bin/measure-chunk-stats.sh` (cleans `.next`, starts `next dev`, triggers compilation, outputs ChunkModuleStats)
+
+### Reduction Loop
+
+The following loop repeats until the user declares completion:
+
+1. **Measure** — Run `bin/measure-chunk-stats.sh`, record `initial` / `async-only` / `total` in `analysis-ledger.md`
+2. **Analyze & Propose** — Analyze the initial chunk module graph, identify the top contributors, and propose one or more reduction approaches (e.g., `next/dynamic`, import refactoring, dependency replacement). Alternatively, if further reduction is impractical, propose ending the loop.
+3. **User Decision** — The user approves the proposed approach, adjusts it, or declares the loop complete.
+4. **Implement & Verify** — Apply the approved changes, then run `turbo run lint:typecheck --filter @growi/app && turbo run lint:biome --filter @growi/app`. Fix any errors before returning to step 1.
+
+### Task Log
+
+- [x] 8.1 Phase 1 sufficiency assessment
+  - **Assessment: Phase 1 is insufficient for compilation time reduction.** Changes are code quality improvements only.
+  - Full assessment documented in `analysis-ledger.md`
+  - _Requirements: 5.1_
+
+- [x] 8.2 Establish ChunkModuleStats KPI and measurement tooling
+  - Created `ChunkModuleStatsPlugin` in `src/utils/next.config.utils.js`
+  - Created `bin/measure-chunk-stats.sh` for one-command measurement
+  - Baseline recorded: initial: 2,704 / async-only: 4,146 / total: 6,850
+  - _Requirements: 2.1, 6.1_
+
+- [x] 8.3 Loop iteration 1: MermaidViewer dynamic import + date-fns subpath imports
+  - MermaidViewer → `next/dynamic({ ssr: false })` in client renderer
+  - date-fns barrel → subpath imports (12 files)
+  - Result: initial: 2,128 (-576, -21.3%) / async-only: 4,717 / total: 6,845
+  - _Requirements: 7.2, 4.1, 6.1_
+
+- [x] 8.4 Loop iteration 2: date-fns locale barrel → individual subpath imports
+  - Converted `locale-utils.ts` import from `date-fns/locale` barrel (96 locales × 6 modules = ~576 modules) to individual subpath imports (`date-fns/locale/en-US`, `/fr`, `/ja`, `/ko`, `/zh-CN`)
+  - Updated `locale-utils.spec.ts` import paths to match
+  - Enhanced `ChunkModuleStatsPlugin` with `DUMP_INITIAL_MODULES=1` diagnostic mode for per-package breakdown
+  - Result: initial: 1,630 (-498, -23.4%) / async-only: 4,717 / total: 6,347 / compiled: 9,062
+  - date-fns: 560 → 62 modules in initial chunks
+  - _Requirements: 4.1, 6.1_
+
+- [x] 8.5 Loop iteration 3: null-loader expansion for server-only package leaks
+  - Added null-loader rules for `i18next-fs-backend` (server-only filesystem translation backend leaking via next-i18next), `bunyan` (server-only logging; client uses browser-bunyan via universal-bunyan), and `bunyan-format` (server-only log formatter)
+  - Null-loading bunyan eliminated its entire transitive dependency tree: mv, ncp, mkdirp, rimraf, glob, source-map, source-map-support, and other Node.js utilities
+  - Result: initial: 1,572 (-58, -3.6%) / async-only: 4,720 / total: 6,292 / compiled: 9,007
+  - _Requirements: 3.1, 3.2, 6.1_
+
+- [x] 8.6 Loop iteration 4: validator → isMongoId regex replacement in LinkEditModal
+  - Replaced `import validator from 'validator'` with lightweight `isMongoId()` regex utility (`/^[0-9a-f]{24}$/i`)
+  - Created `src/client/util/mongo-id.ts` with `isMongoId()` and `mongo-id.spec.ts` with 8 unit tests (TDD)
+  - Eliminated all 113 `validator` modules from async-only chunks (single usage: `validator.isMongoId()` in LinkEditModal.tsx)
+  - Result: initial: 1,572 (unchanged) / async-only: 4,608 (-112, -2.4%) / total: 6,180 (-112) / compiled: 8,895 (-112)
+  - _Requirements: 4.1, 6.1_
+
+- [x] 8.7 Loop iteration 5: react-hotkeys → tinykeys migration
+  - Replaced `react-hotkeys` (91 async modules) with `tinykeys` (~400 byte, 1 module)
+  - Rewrote `HotkeysManager.tsx` to use tinykeys directly with inline key bindings
+  - Deleted `HotkeysDetector.jsx` (unused), `HotkeyStroke.js` (unused model)
+  - Removed `getHotkeyStrokes()` static methods from all 6 subscriber components
+  - Removed `react-hotkeys` dependency, added `tinykeys` dependency
+  - Added `HotkeysManager.spec.tsx` with 6 tests (single keys, modifier keys, editable target suppression)
+  - Refactored all 6 subscriber components to align with ideal patterns:
+    - Converted 4 JSX files to TypeScript (CreatePage, FocusToGlobalSearch, ShowStaffCredit, SwitchToMirrorMode)
+    - Fixed `onDeleteRender(this)` bug in 3 files (`this` is undefined in functional components)
+    - Replaced PropTypes with TypeScript `Props` type in all subscribers
+    - Removed unnecessary `React.memo` wrapper from CreatePage
+    - Unified return values: `return null` for logic-only components
+    - Converted all 6 subscribers from default exports to named exports
+  - Result: initial: 1,573 (+1) / async-only: 4,516 (-92) / total: 6,089 (-91) / compiled: 8,802 (-93)
+  - _Requirements: 4.1, 6.1_
+
+- [x] 8.8 Loop iteration 6: markdown rendering pipeline → next/dynamic({ ssr: true })
+  - Created `PageContentRenderer` wrapper component encapsulating `RevisionRenderer` + `generateSSRViewOptions`
+  - Converted `PageContentRenderer` to `next/dynamic({ ssr: true })` in both `PageView.tsx` and `ShareLinkPageView.tsx`
+  - Moves entire markdown pipeline (react-markdown, katex, remark-gfm, rehype-katex, mdast-util-to-markdown, etc.) to async chunks while preserving SSR rendering
+  - Added `PageContentRenderer.spec.tsx` with 3 tests (null markdown, generated options, explicit options)
+  - Result: initial: 1,073 (-500, -31.8%) / async-only: 5,016 (+500) / total: 6,089 (unchanged) / compiled: 8,803 (+1)
+  - _Requirements: 7.2, 6.1_
+
+- [x] 8.9 Loop iteration 7: core-js null-load + ChunkModuleStatsPlugin analysis fix
+  - Added null-loader rule for `core-js` on client side — polyfills baked into next-i18next/react-stickynode dist files; all APIs natively supported by target browsers (Chrome 64+, Safari 12+)
+  - Null-loading eliminates 179 core-js transitive dependency modules; 37 entry-point modules remain as empty stubs
+  - Fixed `ChunkModuleStatsPlugin` to strip webpack loader prefixes (e.g., `source-map-loader!/path`) before package attribution — corrects 82 previously misattributed modules
+  - Result: initial: 894 (-179, -16.7%) / async-only: 5,011 (-5) / total: 5,905 (-184) / compiled: 8,619 (-184)
+  - _Requirements: 3.1, 3.2, 6.1_
+
+- [x] 8.10 Loop iteration 8: react-syntax-highlighter deep ESM import + v16 upgrade
+  - Changed barrel import `import { PrismAsyncLight } from 'react-syntax-highlighter'` to deep ESM import `import PrismAsyncLight from 'react-syntax-highlighter/dist/esm/prism-async-light'` in all 4 usage files
+  - Changed style import from `dist/cjs/styles/prism` barrel to `dist/esm/styles/prism/one-dark` direct import
+  - Upgraded react-syntax-highlighter from 15.5.0 to 16.1.0 (refractor v3→v5 security fix, webpack 5 improvements, API unchanged)
+  - Deep import bypasses barrel that re-exports all engines (highlight.js, Prism, etc.); only Prism/refractor engine is bundled
+  - Remaining highlight.js modules (~149) still present via other paths (diff2html, lowlight)
+  - Result: initial: 895 (+1) / async-only: 4,775 (-236, -4.7%) / total: 5,670 (-235)
+  - _Requirements: 4.1, 6.1_
+
+- [ ] 8.N Loop iteration N: (next iteration — measure, analyze, propose, implement)
+
+## Phase 3: Next.js Version Upgrade Evaluation (Deferred)
+
+- [ ] 9.1 Document Next.js 15+ feature evaluation
+  - Document which Next.js 15+ features (`bundlePagesRouterDependencies`, `serverExternalPackages`, Turbopack, improved tree-shaking) are relevant to further module reduction
+  - Assess the `next-superjson` compatibility blocker and identify mitigation options
+  - _Requirements: 1.1, 1.2, 1.3, 5.1, 5.4_
+
+- [ ] 9.2 Execute Next.js 15 upgrade (conditional on 9.1 decision)
+  - _Requirements: 5.2, 5.3_
+
+- [ ] 9.3 Enable v15-specific module optimization features
+  - _Requirements: 3.4, 5.2_
+
+- [ ] 9.4 Run full regression test suite after upgrade
+  - _Requirements: 5.3, 6.2, 6.3_
