Signed & Sealed

## 2.3.0 — Turnstiles, Archives & Wall Posters

### Added

- **Wall posters** — hang a published newspaper, leaflet or "WANTED" poster straight on a wall with **Shift + right-click**. No item frames needed.
  - Right-click a poster to read it, Shift + right-click to resize it (1, 2 or 3 blocks wide).
  - Hit it to take it down; it falls off if the wall block is removed. Only published issues can be hung.
- **Ticket Gate** (redstone + 4 iron) — a turnstile with a validator and a barrier arm. The closed arm blocks the passage and is too high to jump over.
  - Hold a ticket and right-click the validator: a valid ticket drops the arm for 1–10 seconds and gives a redstone signal. Showing another ticket while it's open keeps it open. Good for metro, train platforms, cinemas and events.
  - **Gate modes** — punch the ticket (a punched ticket won't pass again and shows where and when it was punched), keep the ticket, or only check it.
  - **Ticket filter** — accept only tickets whose template or organisation contains given words, e.g. "metro, line 2".
  - **Settings** — Shift + right-click with an empty hand (owner only): name, filter, mode, open time, lock and allowed players.
- **Archive Shelf** (planks + wooden slabs + book) — 12 places on two shelves. You can see what's inside: folders and passports stand as spines, documents, newspapers and letters lie in a stack at their real size, every sheet showing its edge. The top sheet shows its actual page — text, signatures and stamps.
- **Filing Cabinet** (iron + chest) — 48 places for big collections.
  - Both store documents, passports, newspapers, letters and whole folders. The GUI has search, view without taking out, take, put from hand and put everything from your inventory at once. Comparators read how full they are.
  - Owners can label an archive, lock it and list who may open it.
- **Chiseled Bookshelf** — documents, passports, newspapers, envelopes and folders now fit in the vanilla chiseled bookshelf.
- **Scanner** (glass panes + iron + redstone) — right-click with a document, passport, published newspaper, opened letter or a folder (every item inside gets scanned). The record keeps the metadata and the authenticity result at scan time.
- **Computer** (iron + glass pane + redstone block + stone buttons) — a green-screen terminal for the digital archive.
  - Search by title, name, date or number; see type, archive number, author, holder, date, who scanned it and whether it was genuine.
  - Open any record without the paper original. Print a paper copy of a document (1 paper, marked "COPY"). Passports and newspapers are never copied.
  - Scanners and computers with the same network name share one archive (up to 5,000 records per network). The owner can lock them and delete records.

### Changed

- A locked archive, gate, scanner or computer can only be broken by its owner or an operator.
- Punched tickets show where and when in the tooltip ("Punched: gate name, date").
- **New permission** — `signedsealed.archive.scan`, allowed by default. Printing copies uses the existing `signedsealed.print`.

### ⚠️ Important

- **Update both client and server** — the network protocol has changed.
- **Back up `data/signedsealed.dat`** — it now also stores the digital archives.
