+
+## Monorepo Structure
+
+- `server/` — Java 21 + Spring Boot 3.5 + Gradle (Kotlin DSL) REST API backend
+- `web/` — React 19 + Vite 8 + TypeScript + Ant Design 6 + Tailwind CSS 4 frontend
+
+## Server
+
+### Coding Standards
+
+- **Style**: Follow the Google Java Coding Style as the foundation.
+- **Indentation**: Use 4 spaces — no tabs.
+- **Line length**: Maximum 100 characters per line.
+- **Comments**: All code comments must use British English spelling (e.g. "colour" not "color", "behaviour" not "behavior", "serialise" not "serialize", "analyse" not "analyze", "traveller" not "traveler").
+
+### Build & Test Commands
+
+```bash
+cd server
+
+# Build the project (skip tests)
+./gradlew build -x test
+
+# Run all tests
+./gradlew test
+
+# Run a single test class
+./gradlew test --tests "com.onixbyte.ahsarahguide.service.PasswordEncoderTest"
+
+# Build the full JAR
+./gradlew bootJar
+```
+
+The project uses Gradle with Java 21 (Amazon Corretto). Tests use JUnit 5 with the Spring Boot test framework, H2 in-memory database for test runtime, and Spring Security test support. Tests require an active `dev` profile.

+```
+
+### Key design decisions
+
+- **JPA + native queries**: Most CRUD uses Spring Data JPA. Native queries (in `ModificationRepository`) handle JSONB tag filtering with Postgres `@>` operator.
+- **Custom auth flow**: JWT tokens in httpOnly cookies (`AccessToken`). Spring Security with a custom `UsernamePasswordAuthenticationProvider` and `TokenAuthenticationFilter`. Tokens are auto-renewed within 5 min of expiry.
+- **JSONB storage**: `Modification.tags` and `Modification.accessories` (including nested `Tuning` objects) are stored as JSONB columns using Hypersistence Utils `JsonType`.
+- **Strict layering**: The call chain must follow `Controller → Service → Manager → Repository/Mapper`. Skipping layers (e.g. Controller calling Manager directly, Service calling Repository directly) is not permitted.
+- **DTOs as Java records**: All request/response objects are immutable records with static `from()` factory methods for entity→DTO conversion.
+- **Flyway migrations**: SQL migrations in `src/main/resources/db/migration/`.

+
+### Architecture
+
+Chinese-language SPA for browsing and managing Ahsarah Guide (阿萨拉向导). The frontend talks to the Spring Boot backend via REST APIs.
+
+**App shell** (`src/main.tsx`): React 19 + React Router 7 + Redux Toolkit + Ant Design 6 + Tailwind CSS 4. Wraps the router in Redux `Provider` → `PersistGate` (Redux Persist) → Ant Design `StyleProvider`/`ConfigProvider` (locale `zh_CN`).
+
+**Routing** (`src/router/index.tsx`): Two layout groups:
+- `HeroLayout` (nav header + footer) for `/`, `/firearms`, `/mod-codes`
+- `EmptyLayout` (minimal) for `/login`
+All page components are lazy-loaded via `createBrowserRouter` + `lazy()`.
+
+**State** (`src/store/`): Redux Toolkit with two slices — `auth` (current user) and `firearms` (paginated firearm list). State is persisted to `localStorage` or `sessionStorage` based on the `VITE_REDUX_STORAGE` env var. Use typed hooks from `src/hooks/store.ts` (`useAppDispatch`, `useAppSelector`).
+
+**API layer** (`src/api/`): Axios instance (`src/shared/web-client/`) with base URL from `VITE_API_BASE_URL`, 10s timeout, and credentials. API modules: `FirearmApi`, `ModificationApi`, `TagApi`, `AuthApi`.
+
+**Pages**:
+- `FirearmsPage` — paginated card grid with type filter, create/edit modals (admin-only), delete with popconfirm
+- `ModCodesPage` — paginated list with tag multi-select and firearmId query param filter, create/edit modals with nested accessory/tuning form lists
+- `LoginPage` — simple username/password form, dispatches `setCurrentUser` on success
+
+**Shared form components**: `FirearmForm` and `ModificationForm` are reused by both create and edit modals. `ModificationForm` fetches all firearms for its weapon selector and supports a `lockFirearmId` prop that disables the selector (used when navigating from a specific firearm).
+
+**Type system** (`src/types/`): `Firearm` with weapon stats, `Modification` with nested `Accessory[]` → `Tuning[]`, `Page<T>` for paginated API responses, `User` for auth.
+
+**Vite config**: Alias `@` → `./src`. Plugins: React, Tailwind CSS 4, port checker. Build uses rolldown with manual chunk splitting for React, Redux, Ant Design, React Router, and rc-* packages.
+
+**Styling**: Tailwind CSS 4 with CSS layers (`theme, base, antd, components, utilities`). Responsive grid for mod code cards (1→2→3→4 columns). Prettier: 100 print width, no semicolons, double quotes, trailing commas ES5.
+
+### Environment variables
+
+```
+VITE_API_BASE_URL=/api        # Backend API base URL
+VITE_REDUX_STORAGE=local      # "local" or "session" for Redux persistence
+```
+
+### Contributing conventions

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
