+# AGENT.md
+
+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:
+```

+
+## 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>

+
+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.
+
+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`
+
+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.
+
+3) Run the app
+- `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`
+
+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.

+# 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).
