 - 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`). Gracefully handles missing tables (e.g. `releases`) by checking `information_schema.tables`.

+- submodule hygiene:

+### Local File Mirrors
+
+The explorer can optionally show "Local Mirror" links for downloads if you have local copies of the ZXDB and World of Spectrum (WoS) file archives.
+
+#### Configuration
+
+To enable local mirrors, set the following variables in your `.env`:
+
+```bash
+# Absolute paths to your local mirrors
+ZXDB_LOCAL_FILEPATH=/path/to/your/zxdb/mirror
+WOS_LOCAL_FILEPATH=/path/to/your/wos/mirror
+
+# Optional: Remote path prefixes to strip from database links before prepending local paths
+ZXDB_FILE_PREFIX=/zxdb/sinclair/
+WOS_FILE_PREFIX=/pub/sinclair/
+```
+
+#### How it works
+
+1. The app identifies if a download link matches `ZXDB_FILE_PREFIX` or `WOS_FILE_PREFIX`.
+2. It strips the prefix from the database link.
+3. It joins the remaining relative path to the corresponding `*_LOCAL_FILEPATH`.
+4. It checks if the file exists on the local disk.
+5. If the file exists and the environment variable is set, a "Local Mirror" link is displayed in the UI, pointing to a proxy download API (`/api/zxdb/download`).
+
+Note: Obtaining these mirrors is left as an exercise to the host. The paths do not need to share a common parent directory. Both mirrors are optional and independent; you can configure one, both, or neither.

+# WIP: Software Hashes
+
+**Branch:** `feature/software-hashes`
+**Started:** 2026-02-17
+**Status:** Complete
+
+## Plan
+
+Implements [docs/plans/software-hashes.md](software-hashes.md) — a derived `software_hashes` table storing MD5, CRC32 and size for tape-image contents extracted from download zips.
+
+### Tasks
+
+- [x] Create `data/zxdb/` directory (for JSON snapshot)
+- [x] Add `software_hashes` Drizzle schema model
+- [x] Create `bin/update-software-hashes.mjs` — main pipeline script
+  - [x] DB query for tape-image downloads (filetype_id IN 8, 22)
+  - [x] Resolve local zip path via CDN mapping (uses CDN_CACHE env var)
+  - [x] Extract `_CONTENTS` (skip if exists)
+  - [x] Find tape file (.tap/.tzx/.pzx/.csw) with priority order
+  - [x] Compute MD5, CRC32, size_bytes
+  - [x] Upsert into software_hashes
+  - [x] State file for resume support
+- [x] JSON export after bulk update (atomic write)
+- [x] Update `bin/import_mysql.sh` to reimport snapshot on DB wipe
+- [x] Add pnpm script entries
+
+## Progress Log
+
+### 2026-02-17T16:00Z
+- Started work. Branch created from `main` at `b361201`.
+- Explored codebase: understood DB schema, CDN mapping, import pipeline.
+- Key findings:
+  - filetype_id 8 = "Tape image" (33,427 rows), 22 = "BUGFIX tape image" (98 rows)
+  - CDN_CACHE = /Volumes/McFiver/CDN, paths: SC/ (zxdb) and WoS/ (pub)
+  - `_CONTENTS` dirs exist in WoS but not yet in SC
+  - data/zxdb/ directory needs creation
+  - import_mysql.sh needs software_hashes reimport step
+
+### 2026-02-17T16:04Z
+- Implemented Drizzle schema model for `software_hashes`.
+- Created `bin/update-software-hashes.mjs` pipeline script.
+- Updated `bin/import_mysql.sh` with JSON snapshot reimport.
+- Added `update:hashes` and `export:hashes` pnpm scripts.
+
+### 2026-02-17T16:09Z
+- First full run completed successfully:
+  - 33,525 total tape-image downloads in DB
+  - 32,305 rows hashed and inserted into software_hashes
+  - ~1,220 skipped (missing local zips, `/denied/` prefix, `.p` ZX81 files with no tape content)
+  - JSON snapshot exported: 7.2MB, 32,305 rows at `data/zxdb/software_hashes.json`
+- All plan steps verified working.
+
+## Decisions & Notes
+
+- Target filetype IDs: 8 and 22 (tape image + bugfix tape image).
+- Tape file priority: .tap > .tzx > .pzx > .csw (most common first).
+- CDN_CACHE comes from env var (not hard-coded, unlike sync-downloads.mjs).
+- JSON snapshot at data/zxdb/software_hashes.json (7.2MB, committed to repo).
+- Node.js built-in `crypto` for MD5; custom CRC32 lookup table (no external deps).
+- `inner_path` column added (not in original plan) to record which file inside the zip was hashed.
+- `/denied/` and `/nvg/` prefix downloads (~443) are logged and skipped (no local mirror).
+- `.p` files (ZX81 programs) categorized as tape images but contain no .tap/.tzx/.pzx/.csw — logged as "no tape file".
+- Uses system `unzip` for extraction (handles bracket-heavy filenames via `execFile` not shell).

+# Software Hashes Plan
+
+Plan for adding a derived `software_hashes` table, its update pipeline, and JSON snapshot lifecycle to survive DB wipes.
+
+---
+
+## 1) Goals and Scope (Plan Step 1)
+
+- Create and maintain `software_hashes` for (at this stage) tape-image downloads.
+- Preserve existing `_CONTENTS` folders; only create missing ones.
+- Export `software_hashes` to JSON after each bulk update.
+- Reimport `software_hashes` JSON during DB wipe in `bin/import_mysql.sh` (or a helper script it invokes).
+- Ensure all scripts are idempotent and resume-safe.
+
+---
+
+## 2) Confirm Pipeline Touchpoints (Plan Step 2)
+
+- Verify `bin/import_mysql.sh` is the authoritative DB wipe/import entry point.
+- Confirm `bin/sync-downloads.mjs` remains responsible only for CDN cache sync.
+- Confirm `src/server/schema/zxdb.ts` uses `downloads.id` as the natural FK target.
+
+---
+
+## 3) Define Data Model: `software_hashes` (Plan Step 3)
+
+### Table naming and FK alignment
+
+- Table: `software_hashes`.
+- FK: `download_id` → `downloads.id`.
+- Column names follow existing DB `snake_case` conventions.
+
+### Planned columns
+
+- `download_id` (PK or unique index; FK to `downloads.id`)
+- `md5`
+- `crc32`
+- `size_bytes`
+- `updated_at`
+
+### Planned indexes / constraints
+
+- Unique index on `download_id`.
+- Index on `md5` for reverse lookup.
+- Index on `crc32` for reverse lookup.
+
+---
+
+## 4) Define JSON Snapshot Format (Plan Step 4)
+
+### Location
+
+- Default: `data/zxdb/software_hashes.json` (or another agreed path).
+
+### Structure
+
+```json
+{
+  "exportedAt": "2026-02-17T15:18:00.000Z",
+  "rows": [
+    {
+      "download_id": 123,
+      "md5": "...",
+      "crc32": "...",
+      "size_bytes": 12345,
+      "updated_at": "2026-02-17T15:18:00.000Z"
+    }
+  ]
+}
+```
+
+### Planned import policy
+
+- If snapshot exists: truncate `software_hashes` and bulk insert.
+- If snapshot missing: log and continue without error.
+
+---
+
+## 5) Implement Tape Image Update Workflow (Plan Step 5)
+
+### Planned script
+
+- `bin/update-software-hashes.mjs` (name can be adjusted).
+
+### Planned input dataset
+
+- Query `downloads` for tape-image rows (filter by `filetype_id` or joined `filetypes` table).
+
+### Planned per-item process
+
+1. Resolve local zip path using the same CDN mapping used by `sync-downloads`.
+2. Compute `_CONTENTS` folder name: `<zip filename>_CONTENTS` (exact match).
+3. If `_CONTENTS` exists, keep it untouched.
+4. If missing, extract zip into `_CONTENTS` using a library that avoids shell expansion issues with brackets.
+5. Locate tape file inside (`.tap`, `.tzx`, `.pzx`, `.csw`):
+   - Apply a deterministic priority order.
+   - If multiple candidates remain, log and skip (or record ambiguity).
+6. Compute `md5`, `crc32`, and `size_bytes` for the selected file.
+7. Upsert into `software_hashes` keyed by `download_id`.
+
+### Planned error handling
+
+- Log missing zips or missing tape files.
+- Continue after recoverable errors; fail only on critical DB errors.
+
+---
+
+## 6) Implement JSON Export Lifecycle (Plan Step 6)
+
+- After each bulk update, export `software_hashes` to JSON.
+- Write atomically (temp file + rename).
+- Include `exportedAt` timestamp in snapshot.
+
+---
+
+## 7) Reimport During Wipe (`bin/import_mysql.sh`) (Plan Step 7)
+
+### Planned placement
+
+- Immediately after database creation and ZXDB SQL import completes.
+
+### Planned behavior
+
+- Attempt to read JSON snapshot.
+- If present, truncate and reinsert `software_hashes`.
+- Log imported row count.
+
+---
+
+## 8) Add Idempotency and Resume Support (Plan Step 8)
+
+- State file similar to `.sync-downloads.state.json` to track last `download_id` processed.
+- CLI flags:
+  - `--resume` (default)
+  - `--start-from-id`
+  - `--rebuild-all`
+- Reprocess when zip file size or mtime changes.
+
+---
+
+## 9) Validation Checklist (Plan Step 9)
+
+- `_CONTENTS` folders are never deleted.
+- Hashes match expected MD5/CRC32 for known samples.
+- JSON snapshot is created and reimported correctly.
+- Reverse lookup by `md5`/`crc32`/`size_bytes` identifies misnamed files.
+- Script can resume safely after interruption.
+
+---
+
+## 10) Open Questions / Confirmations (Plan Step 10)
+
+- Final `software_hashes` column list and types.
+- Exact JSON snapshot path.
+- Filetype IDs that map to “Tape Image” in `downloads`.

+# Plan: Tape Identifier Dropzone on /zxdb
+
+## Context
+
+We have 32,960 rows in `software_hashes` with MD5, CRC32, size, and inner_path for tape-image contents. This feature exposes that data to users: drop a tape file, get it identified against the ZXDB database.
+
+Uses RSC (server actions) rather than an API endpoint to make bulk scripted identification harder.
+
+## Architecture
+
+**Client-side:** Compute MD5 + file size in the browser, then call a server action with just those two values (file never leaves the client).
+
+**Server-side:** A Next.js Server Action looks up `software_hashes` by MD5 (and optionally size_bytes for disambiguation), joins to `downloads` and `entries` to return the entry title, download details, and a link.
+
+**Client-side MD5:** Web Crypto doesn't support MD5. Include a small pure-JS MD5 utility (~80 lines, well-known algorithm). No new npm dependencies.
+
+## Files to Create/Modify
+
+### 1. `src/utils/md5.ts` — Pure-JS MD5 for browser use
+- Exports `async function computeMd5(file: File): Promise<string>`
+- Reads file as ArrayBuffer, computes MD5, returns hex string
+- Standard MD5 algorithm implementation, typed for TypeScript
+
+### 2. `src/app/zxdb/actions.ts` — Server Action
+- `'use server'` directive
+- `identifyTape(md5: string, sizeBytes: number)`
+- Queries `software_hashes` JOIN `downloads` JOIN `entries` by MD5
+- If multiple matches and size_bytes narrows it, filter further
+- Returns array of `{ downloadId, entryId, entryTitle, innerPath, md5, crc32, sizeBytes }`
+
+### 3. `src/app/zxdb/TapeIdentifier.tsx` — Client Component
+- `'use client'`
+- States: `idle` → `hashing` → `identifying` → `results` / `not-found`
+- Dropzone UI:
+  - Dashed border card, large tape icon, "Drop a tape file to identify it"
+  - Lists supported formats: `.tap .tzx .pzx .csw .p .o`
+  - Also has a hidden `<input type="file">` with a "or choose file" link
+  - Drag-over highlight state
+- On file drop/select:
+  - Validate extension against supported list
+  - Show spinner + "Computing hash..."
+  - Compute MD5 + size client-side
+  - Call server action `identifyTape(md5, size)`
+  - Show spinner + "Searching ZXDB..."
+- Results view (replaces dropzone):
+  - Match found: entry title as link to `/zxdb/entries/{id}`, inner filename, MD5, file size
+  - Multiple matches: list all
+  - No match: "No matching tape found in ZXDB"
+  - "Identify another tape" button to reset
+
+### 4. `src/app/zxdb/page.tsx` — Add TapeIdentifier section
+- Insert `<TapeIdentifier />` as a new section between the hero and "Start exploring" grid
+- Wrap in a card with distinct styling to make it visually prominent
+
+### 5. `src/server/repo/zxdb.ts` — Add lookup function
+- `lookupByMd5(md5: string)` — joins `software_hashes` → `downloads` → `entries`
+- Returns download_id, entry_id, entry title, inner_path, hash details
+
+## Verification
+
+- Visit http://localhost:4000/zxdb
+- Dropzone should be visible and prominent between hero and navigation grid
+- Drop a known .tap/.tzx file → should show the identified entry with a link
+- Drop an unknown file → should show "No matching tape found"
+- Click "Identify another tape" → resets to dropzone
+- Check file never leaves browser (Network tab: only the server action call with md5 + size)
+- Verify non-supported extensions are rejected with helpful message

+# ZXDB Explorer — Missing Features & Gaps
+
+Audit of the `/zxdb` pages against the ZXDB schema and existing data. Everything listed below is backed by tables already present in the Drizzle schema (`src/server/schema/zxdb.ts`) but not yet surfaced in the UI.
+
+---
+
+## Current Coverage
+
+| Section        | List page | Detail page | Facets/Filters                  |
+|----------------|-----------|-------------|---------------------------------|
+| Entries        | Search    | Full detail | genre, language, machinetype    |
+| Releases       | Search    | Downloads, scraps, files, magazine refs | — |
+| Labels         | Search    | Authored/published entries, permissions, licenses | — |
+| Magazines      | Search    | Issues list | —                               |
+| Issues         | via magazine | Magazine refs (reviews/references) | —              |
+| Genres         | List      | Entries by genre   | —                      |
+| Languages      | List      | Entries by language | —                     |
+| Machine Types  | List      | Entries by type    | —                      |
+
+---
+
+## Missing Top-Level Browse Pages
+
+### 1. Countries
+- **Tables:** `countries`, `labels.country_id`
+- **Value:** Browse by country ("all software from Spain", "UK publishers").
+
+### 2. Tools
+- **Tables:** `tools`, `tooltypes`
+- **Value:** Utilities, emulators, and development tools catalogued in ZXDB.
+
+### 3. Features
+- **Tables:** `features`
+- **Value:** Hardware/software features (Multiface, Kempston joystick, etc.).
+
+### 4. Topics
+- **Tables:** `topics`, `topictypes`
+- **Value:** Editorial/thematic groupings used by magazines.
+
+### 5. Tags / Collections
+- **Tables:** `tags`, `tagtypes`, `members`
+- **Value:** Tags are shown per-entry but there is no top-level "browse by tag" page (e.g. all CSSCGC entries, compilations).
+
+### 6. Licenses
+- **Tables:** `licenses`, `licensetypes`, `relatedlicenses`, `licensors`
+- **Value:** Shown per-entry detail but no "browse all licenses" hub (e.g. all games based on a Marvel license).
+
+---
+
+## Missing Cross-Links & Facets on Existing Pages
+
+### 7. Magazine reviews on Entry detail
+- Release detail shows magazine refs, but entry detail does **not** aggregate them.
+- A user viewing an entry cannot see "reviewed in Crash #42, p.34" without drilling into each release.
+
+### 8. Year / date filter on Entries
+- ZXDB has `release_year` on releases. No year facet on the entries explorer.
+- Users cannot browse "all games from 1985".
+
+### 9. Availability type filter on Entries
+- `availabletypes` API route exists but is not a facet on the entries explorer.
+- Would allow filtering by "Never released", "MIA", etc.
+
+### 10. Max players filter on Entries
+- `entries.max_players` exists but is not filterable.
+- Would enable "all multiplayer games".
+
+### 11. Label type filter on Labels page
+- `labeltypes` table exists and `roletypes` API is served.
+- Cannot filter the labels list by type (person / company / team / magazine).
+
+### 12. Country filter on Labels page
+- Labels have `country_id` but no filter on the list page.
+
+### 13. Country / language filter on Magazines page
+- Magazine list has search but no country or language filter chips.
+
+---
+
+## Missing Data on Detail Pages
+
+### 14. Entry detail: magazine reviews section
+- `search_by_magrefs` is used in release detail but entry detail does not aggregate magazine references across all releases.
+- Same issue as #7 — the entry page should show a combined reviews/references panel.
+
+### 15. Label detail: country display
+- Labels have `country_id` / `country2_id` but the detail page does not show them.
+
+### 16. Label detail: Wikipedia / website links
+- `labels.link_wikipedia` and `labels.link_site` exist but are not displayed on the label detail page.
+
+### 17. Entry detail: related entries via same license
+- Licenses are shown per-entry but there is no click-through to "other games with this license".
+
+---
+
+## Entirely Unsurfaced Datasets
+
+### 18. NVGs
+- **Table:** `nvgs`
+- Historical download archive metadata. Not exposed anywhere.
+
+### 19. SPEX entries / authors
+- **Tables:** `spex_entries`, `spex_authors`
+- No UI.
+
+### 20. Awards
+- **Table:** `zxsr_awards`, referenced by `magrefs.award_id`
+- No awards browsing or display.
+
+### 21. Review text
+- **Table:** `zxsr_reviews` (`intro_text`, `review_text`)
+- Magazine refs link to reviews by ID but the actual review text is never rendered.
+
+### 22. Articles
+- **Tables:** `articles`, `articletypes`
+- No articles browsing.
+
+---
+
+## Navigation / UX Gaps
+
+### 23. No discovery mechanism
+- No "random entry", "on this day", or "featured" section. Common for large historic databases.
+
+### 24. No stats / dashboard
+- No summary counts ("ZXDB has X entries, Y labels, Z magazines"). Would anchor the landing page.
+
+---
+
+## Suggested Priority
+
+| Priority | Items | Rationale |
+|----------|-------|-----------|
+| High     | 7/14 (magazine refs on entry detail), 8 (year filter), 15-16 (label country + links) | Data exists, just not wired up. High user value. |
+| Medium   | 1 (countries), 5 (tags browse), 6 (licenses browse), 9 (availability filter), 24 (stats) | New pages but straightforward queries. |
+| Low      | 2-4 (tools/features/topics), 10-13 (additional filters), 17-22 (unsurfaced datasets), 23 (discovery) | Useful but niche or requires more design work. |
