+
+This document provides an overview of the Next Explorer project, its structure, and its implementation details.
+
+## Project Overview
+
+Next Explorer is a web application for exploring the Spectrum Next ecosystem. It is built with Next.js (App Router), React, and TypeScript.
+
+It has two main areas:
+- Registers: parsed from `data/nextreg.txt`, browsable with real-time filtering and deep links.
+- ZXDB Explorer: a deep, cross‑linked browser for ZXDB entries, labels, genres, languages, and machine types backed by MySQL using Drizzle ORM.
+
+## Project Structure
+
+The project is a Next.js application with the following structure:
+```

+- **`src/utils/register_parser.ts` & `src/utils/register_parsers/`**: Parsing logic for `nextreg.txt`, including mode/bitfield handling and any register-specific parsing extensions.
+
+## Implementation Details
+
+Comment what the code does, not what the agent has done. The documentation's purpose is the state of the application today, not a log of actions taken.
+
+### Data Parsing
+
+- `getRegisters()` in `src/services/register.service.ts`:
+  - Reads `data/nextreg.txt` from disk.
+  - Uses `parseNextReg()` from `src/utils/register_parser.ts` to convert the raw text into an array of `Register` objects.
+  - Returns the in-memory representation of all registers (and can be extended to cache results across calls).
+
+- `parseNextReg()` and related helpers in `register_parser.ts`:
+  - Parse the custom `nextreg.txt` format into structured data:
+    - Register addresses (hex/dec).
+    - Names, notes, and descriptive text.
+    - Per-mode read/write/common bitfield views.
+    - Optional source lines and external links (e.g. wiki URLs).
+  - Delegate special-case parsing to functions in `src/utils/register_parsers/` (e.g. `reg_default.ts`, `reg_f0.ts`) when needed.
+
+### TypeScript Patterns
+ - No explicity any types.
+ - Use `const` for constants.
+ - Use `type` for interfaces.
+ - No `enum`.
+
+### React / Next.js Patterns
+
+- **Server Components**:
+  - `src/app/registers/page.tsx` and `src/app/registers/[hex]/page.tsx` are Server Components.
+  - ZXDB pages under `/zxdb` server‑render initial content for fast first paint, with ISR (`export const revalidate = 3600`) on non‑search pages.
+  - Server components call repository functions directly on the server and pass data to client components for presentation.
+
+- **Client Components**:
+  - `RegisterBrowser.tsx`:
+    - Marked with `'use client'`.
+    - Uses React state to manage search input and filtered results.
+  - `RegisterDetail.tsx`:
+    - Marked with `'use client'`.
+    - Renders a single register with tabs for different access modes.
+  - ZXDB client components (e.g., `ZxdbExplorer.tsx`, `EntryDetail.tsx`, `labels/*`) receive initial data from the server and keep interactions on the client without blocking the first paint.
+
+- **Dynamic Routing**:
+  - Pages and API routes must await dynamic params in Next.js 15:
+    - Pages: `export default async function Page({ params }: { params: Promise<{ id: string }> }) { const { id } = await params; }`
+    - API: `export async function GET(req, ctx: { params: Promise<{ id: string }> }) { const raw = await ctx.params; /* validate with Zod */ }`
+  - `src/app/registers/[hex]/page.tsx` resolves the `[hex]` segment and calls `notFound()` if absent.
+
+### ZXDB Integration
+
+- Database connection via `mysql2` pool wrapped by Drizzle (`src/server/db.ts`).
+- Env validation via Zod (`src/env.ts`) ensures `ZXDB_URL` is a valid `mysql://` URL.
+- Minimal Drizzle schema models used for fast search and lookups (`src/server/schema/zxdb.ts`).
+- Repository consolidates SQL with typed results (`src/server/repo/zxdb.ts`).
+- API routes under `/api/zxdb/*` validate inputs with Zod and run on Node runtime.
+- UI under `/zxdb` is deeply cross‑linked and server‑renders initial data for performance. Links use Next `Link` to enable prefetching.
+  - Helper SQL `ZXDB/scripts/ZXDB_help_search.sql` must be run to create `search_by_*` tables for efficient searches.
+  - Lookup tables use column `text` for display names; the Drizzle schema maps it as `name`.
+
+### Working Patterns***
+
+- git branching:
+  - Do not create new branches
+- git commits:
+  - Create COMMIT_EDITMSG file, await any user edits, then commit using that 
+    commit note, and then delete the COMMIT_EDITMSG file. Remember to keep
+    the first line as the subject <50char
+- git commit messages:
+  - Use imperative mood (e.g., "Add feature X", "Fix bug Y").
+  - Include relevant issue numbers if applicable.
+  - Sign-off commit message as Junie@<hostname>

+Spectrum Next Explorer
 
-## Getting Started
+A Next.js application for exploring the Spectrum Next ecosystem. It ships with:
 
-First, run the development server:
+- Register Explorer: parsed from `data/nextreg.txt`, with real‑time search and deep links
+- ZXDB Explorer: a deep, cross‑linked browser for entries, labels, genres, languages, and machine types backed by a MySQL ZXDB instance
+- Bootstrap 5 theme with light/dark support
 
-```bash
+Quick start
-npm run dev
+- Prerequisites: Node.js 20+, pnpm (recommended), access to a MySQL server for ZXDB (optional for Registers)
-# or
+- Install dependencies:
-yarn dev
+  - `pnpm install`
-# or
+- Run in development (Turbopack, port 4000):
-pnpm dev
+  - `pnpm dev` then open http://localhost:4000
-# or
+- Build and start (production):
-bun dev
+  - `pnpm build`
-```
+  - `pnpm start` (defaults to http://localhost:3000)
+- Lint:
+  - `pnpm lint`
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+Project scripts (package.json)
+- `dev`: `PORT=4000 next dev --turbopack`
+- `build`: `next build --turbopack`
+- `start`: `next start`
+- `deploy-test`: push to `test.explorer.specnext.dev`
+- `deploy-prod`: push to `explorer.specnext.dev`
 
-You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+Routes
+- `/` — Home
+- `/registers` — Register Explorer
+- `/zxdb` — ZXDB Explorer (search + filters)
+- `/zxdb/entries/[id]` — Entry detail
+- `/zxdb/labels` and `/zxdb/labels/[id]` — Labels search and detail
+- `/zxdb/genres` and `/zxdb/genres/[id]` — Genres list and entries
+- `/zxdb/languages` and `/zxdb/languages/[id]` — Languages list and entries
+- `/zxdb/machinetypes` and `/zxdb/machinetypes/[id]` — Machine types list and entries
 
-This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+ZXDB setup (database, env, and helper tables)
+The Registers section works without any database. The ZXDB Explorer requires a MySQL ZXDB database and one environment variable.
 
-## Learn More
+1) Prepare the database (outside this app)
+- Import ZXDB data into MySQL. If you want only structure, use `ZXDB/ZXDB_mysql_STRUCTURE_ONLY.sql` in this repo. For data, import ZXDB via your normal process.
+- Create the helper search tables (required for fast search):
+  - Run `ZXDB/scripts/ZXDB_help_search.sql` against your ZXDB database.
+- Create a read‑only role/user (recommended):
+  - Example (see `bin/import_mysql.sh`):
+    - Create role `zxdb_readonly`
+    - Grant `SELECT, SHOW VIEW` on database `zxdb`
 
-To learn more about Next.js, take a look at the following resources:
+2) Configure environment
+- Copy `.env` from `example.env`.
+- Set `ZXDB_URL` to a MySQL URL, e.g. `mysql://zxdb_readonly:password@hostname:3306/zxdb`.
+- On startup, `src/env.ts` validates env vars (t3.gg pattern with Zod) and will fail fast if invalid.
 
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+3) Run the app
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+- `pnpm dev` → open http://localhost:4000 and navigate to `/zxdb`.

+API (selected endpoints)
+- `GET /api/zxdb/search?q=...&page=1&pageSize=20&genreId=...&languageId=...&machinetypeId=...&sort=title&facets=1`
+- `GET /api/zxdb/entries/[id]`
+- `GET /api/zxdb/labels/search?q=...`
+- `GET /api/zxdb/labels/[id]?page=1&pageSize=20`
+- `GET /api/zxdb/genres` and `/api/zxdb/genres/[id]?page=1`
+- `GET /api/zxdb/languages` and `/api/zxdb/languages/[id]?page=1`
+- `GET /api/zxdb/machinetypes` and `/api/zxdb/machinetypes/[id]?page=1`
 
-## Deploy on Vercel
+Implementation notes
+- Next.js 15 dynamic params: pages and API routes that consume `params` must await it, e.g. `export default async function Page({ params }: { params: Promise<{ id: string }> }) { const { id } = await params; }`
+- ZXDB integration uses Drizzle ORM over `mysql2` with a singleton pool at `src/server/db.ts`; API routes declare `export const runtime = "nodejs"`.
+- Entry and detail pages server‑render initial content and use ISR (`revalidate = 3600`) for fast time‑to‑content; index pages avoid a blocking first client fetch.
 
-The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.

+# ZXDB Guide
+
+This document explains how the ZXDB Explorer works in this project, how to set up the database connection, and how to use the built‑in API and UI for software discovery.
+
+## What is ZXDB?
+
+ZXDB ( https://github.com/zxdb/ZXDB )is a community‑maintained database of ZX Spectrum software, publications, and related entities. In this project, we connect to a MySQL ZXDB instance in read‑only mode and expose a fast, cross‑linked explorer UI under `/zxdb`.
+
+## Prerequisites
+
+- MySQL server with ZXDB data (or at minimum the tables; data is needed to browse).
+- Ability to run the helper SQL that builds search tables (required for efficient LIKE searches).
+- A read‑only MySQL user for the app (recommended).
+
+## Database setup
+
+1. Import ZXDB data into MySQL.
+   - Extract and import https://github.com/zxdb/ZXDB/blob/master/ZXDB_mysql.sql.zip
+
+2. Create helper search tables (required).
+   - Run `https://github.com/zxdb/ZXDB/blob/master/scripts/ZXDB_help_search.sql` on your ZXDB database.
+   - This creates `search_by_titles`, `search_by_names`, `search_by_authors`, and `search_by_publishers` tables.
+
+3. Create a read‑only role/user (recommended).
+   - Create user `zxdb_readonly`.
+   - Grant `SELECT, SHOW VIEW` on your `zxdb` database to the user.
+
+## Environment configuration
+
+Set the connection string in `.env`:
+
+```
+ZXDB_URL=mysql://zxdb_readonly:password@hostname:3306/zxdb
+```
+
+Notes:
+- The URL must start with `mysql://`. Env is validated at boot by `src/env.ts` (Zod), failing fast if misconfigured.
+- The app uses a singleton `mysql2` pool (`src/server/db.ts`) and Drizzle ORM for typed queries.
+
+## Running
+
+```
+pnpm install
+pnpm dev
+# open http://localhost:4000 and navigate to /zxdb
+```
+
+## Explorer UI overview
+
+- `/zxdb` — Search entries by title and filter by genre, language, and machine type; sort and paginate results.
+- `/zxdb/entries/[id]` — Entry details with badges for genre/language/machine, and linked authors/publishers.
+- `/zxdb/labels` and `/zxdb/labels/[id]` — Browse/search labels (people/companies) and view authored/published entries.
+- `/zxdb/genres`, `/zxdb/languages`, `/zxdb/machinetypes` — Category hubs with linked detail pages listing entries.
+
+Cross‑linking: All entities are permalinks using stable IDs. Navigation uses Next `Link` so pages are prefetched.
+
+Performance: Detail and index pages are server‑rendered with initial data and use ISR (`revalidate = 3600`) to reduce time‑to‑first‑content. Queries select only required columns and leverage helper tables for text search.
+
+## HTTP API reference (selected)
+
+All endpoints are under `/api/zxdb` and validate inputs with Zod. Responses are JSON.
+
+- Search entries
+  - `GET /api/zxdb/search`
+  - Query params:
+    - `q` — string (free‑text search; normalized via helper tables)
+    - `page`, `pageSize` — pagination (default pageSize=20, max=100)
+    - `genreId`, `languageId`, `machinetypeId` — optional filters
+    - `sort` — `title` or `id_desc`
+    - `facets` — boolean; if truthy, includes facet counts for genres/languages/machines
+
+- Entry detail
+  - `GET /api/zxdb/entries/[id]`
+  - Returns: entry core fields, joined genre/language/machinetype names, authors and publishers.
+
+- Labels
+  - `GET /api/zxdb/labels/search?q=...`
+  - `GET /api/zxdb/labels/[id]?page=1&pageSize=20` — includes `authored` and `published` lists.
+
+- Categories
+  - `GET /api/zxdb/genres` and `/api/zxdb/genres/[id]?page=1`
+  - `GET /api/zxdb/languages` and `/api/zxdb/languages/[id]?page=1`
+  - `GET /api/zxdb/machinetypes` and `/api/zxdb/machinetypes/[id]?page=1`
+
+Runtime: API routes declare `export const runtime = "nodejs"` to support `mysql2`.
+
+## Implementation notes
+
+- Drizzle models map ZXDB lookup table column `text` to property `name` for ergonomics (e.g., `languages.text` → `name`).
+- Next.js 15 dynamic params must be awaited in App Router pages and API routes. Example:
+  ```ts
+  export default async function Page({ params }: { params: Promise<{ id: string }> }) {
+    const { id } = await params;
+    // ...
+  }
+  ```
+- Repository queries parallelize independent calls with `Promise.all` for lower latency.
+
+## Troubleshooting
+
+- 400 from dynamic API routes: ensure you await `ctx.params` before Zod validation.
+- Unknown column errors for lookup names: ZXDB tables use column `text` for names; Drizzle schema must select `text` as `name`.
+- Slow entry page: confirm server‑rendering is active and ISR is set; client components should not fetch on the first paint when initial props are provided.
+- MySQL auth or network errors: verify `ZXDB_URL` and that your user has read permissions.
+
+## Roadmap
+
+- Facet counts displayed in the `/zxdb` filter UI.
+- Breadcrumbs and additional a11y polish.
+- Media assets and download links per release (future).

+  3. `bootswatch` (theme tweaks)
+  4. `explorer` (project-specific styles)
+
+Theming bootstrap
+- On the server, `layout.tsx` reads the `NBN-theme` cookie (light/dark) and sets `data-bs-theme` on the HTML element.
+- On the client, an inline script in the head ensures no flash of incorrect theme by immediately setting the attribute based on cookie or user preference.

+Register Explorer
+
+Overview
+The Register Explorer lets you browse and search Spectrum Next registers parsed from `data/nextreg.txt`. Each register page shows address, access details, bit tables, and notes.
+
+Searching
+- Use the search input to filter registers in real time.
+- The query is case‑insensitive and matches a combined `search` field per register (name, address, and keywords).
+
+Deep links (query string)
+- The search box syncs with the `q` query parameter so searches are shareable.
+- Example: `/registers?q=vram`
+  - When you open this URL, the search box is pre‑filled with `vram` and the list is filtered immediately.
+- Clearing the search removes `q` from the URL.
+
+Implementation notes
+- Component: `src/app/registers/RegisterBrowser.tsx`
+- Uses Next.js navigation hooks: `useSearchParams`, `useRouter`, `usePathname`.
+- On mount and when the URL changes, the component reads `q` and updates local state.
+- On input change, the component updates state and calls `router.replace()` to keep the URL in sync without scrolling.
