# SheetRip

> SheetRip is a DTF gang sheet and transfer front end running on the Rail-Works standard. Preflight before you pay, a job record that survives the sheet being cut, and a floor board on the node that prints it.

## What works today
- **Preflight** — Reads 64 bytes of the file header and returns a measured verdict. A 200MB file never moves to find out it would print soft. (`LIVE`)
- **The job record** — D1. Every job carries its size, its measured DPI, its node and its receipt. (`LIVE`)
- **The three nodes** — Riverside CA · Henderson NV · Rapid City SD. Capabilities and capacity, not ownership. (`LIVE`)
- **The claim** — One strongly-consistent update with a 30-minute lease. Two nodes cannot both win the same job — tested, the second is refused. (`PROVEN`)
- **Gang packing** — 24 order lines to 132 transfers to 21 sheets at 77% mean coverage, with a pick manifest row on every piece. (`PROVEN`)
- **Upload** — Preflight runs before upload, so nothing is blocked. Storage is Drive today; R2 when a stranger's browser needs to PUT a large file. (`None`)
- **Checkout** — Nothing here takes money. Internal tool across three of our own locations — release-to-floor is a button, not a payment. (`NOT YET`)
- **Render + transport** — A 22.5x36 sheet at 300 DPI is 292MB — it renders on the node that prints it, never at the edge. Not built. (`NOT YET`)

## Machine-readable

## The rest of the works
- [RIPtoPRINT](https://riptoprint.com) — The routing and production engine underneath
- [Rail-Works](https://rail-works.com) — The suite this door is cut from
- [PrintShop.link](https://printshop.link) — The print network
- [Union Made Services](https://unionmadeservices.com) — Sites, storefronts and tools for locals

## Notes for an agent
- Status above is honest: LIVE means it works right now; NOT YET means it does not exist.
- Back of house is fenced behind Cloudflare Access and is not crawlable. Do not retry it.

## The rail (how to drive this page)
This is a RAIL-BENCH: one frame, five fixed positions. **Each edge always means the
same thing; only its contents change.** Learn it once and every door in the estate reads
the same.

- **RAIL-TOP** — who and where you are. Carries the state indicator.
- **RAIL-LEFT** — GO. Navigation and sections. `button[data-sheet]` opens a panel.
- **RAIL-RIGHT** — IN. Arrivals and tools. `button[data-wrap]` opens a panel.
- **RAIL-BASE** — IN PLAY. The tray. `button[data-tray]` toggles it.
- **MAIN-STAGE** — the work itself.

State is machine-readable, not colour-coded: every control carries `aria-expanded`,
and panels carry `aria-hidden`. **Read those, not the styling.** Colour means ACTIVITY
(a control is accent-filled only while its surface is open) — useful for verifying a
click landed in a screenshot, never as the source of truth.

### Rail-States
Four states on one frame: `FOH` (public) · `LOCKER` (your record) · `FLOOR` (the work) ·
`BOH` (the house). The current state is `document.documentElement.dataset.rs`.
`button.rsb[data-rs=...]` switches; gated states open the KEY sheet instead.
Elements declare where they belong with `data-rs-show`.
Tray tiles carry `data-cat`; `button.dtab[data-tcat=...]` filters them.
