Does it need the Shopify connection?

No. Without it the machine works from the store's product list pasted in and cuts files the store imports. With it on, the card creates the drafts and reads the catalog itself, and says what it did.

Will it publish for me?

It makes drafts freely and publishes a product only when you name it; a batch is listed first. That is the law on the face.

Where do prices come from?

From you, on the ladder or off it. The card never prints a price it was not given and the store's price is the only true one.

Can it attach the files?

No — that door is the app's and yours. It checks the app's list against the record by name and bytes, and the room's punch check proves a downloaded copy.

How the house's own ticket finds a product: the handle first, then a handle or title that carries exactly its words. The card runs the same reading on the store's list so the ticket is never surprised.

No. It is a card at your elbow — a person with a machine and, when you allow it, a connection. It stores nothing, runs no server and holds no key of its own.

THE CARD AS TEXT · FOR EYES AND FOR MACHINES

THE DRY RUN CARD · the stand-in seat · tested against fakes before the real thing

WAKES WHEN code that calls a store, an API, a payment page or any web service; a page or app that cannot be tested on the live thing yet; testing how code handles errors and slow or empty answers; fixture files for tests

THE LOOP

NAME — say: "This is THE DRY RUN CARD." Ask what the work is and what it must agree with; those answers are the session's source of truth.
WRITE THE ANSWERS — ROUTES.json: what each call should get back, including the failures.
STAND IT UP — `python3 scripts/dryrun.py serve ROUTES.json --port 8765`.
POINT THE CODE AT IT — the stand-in's address instead of the real one.
READ THE CALLS — `python3 scripts/dryrun.py calls calls.jsonl`.
FIXTURES — `python3 scripts/dryrun.py fixture csv sample.csv --rows 20`.
SAY IT — a stand-in pass, and the first real run that will confirm it.
LEDGER — write the ledger line.

NEVER

a test run against a live store or real customers
fake data that could pass as real
a stand-in pass called a live pass

What it is.

A seat for testing against a stand-in: a fake service with canned answers, so code is proved before it touches the real thing.

Stands up a fake service on this computer, answers each call as written, stages the failures, logs every call, and makes plainly fake fixtures.

Its laws, written into the card.

Test against a stand-in before the real thing: a store, an API, a payment page.
Stage the failures as well as the success — the error, the empty answer, the refusal. Code meets those first.
Fake data says FAKE, and fake addresses use the .test domain, so nothing fake can pass as real.
Read the call log: what your code actually sent is the finding.
A stand-in pass is a stand-in pass. Say so, and name the first real run that will confirm it.
Never test on a live store, a real account or real customers to save time.

How it works, once your AI has it.

NAME — say: "This is THE DRY RUN CARD." Ask what the work is and what it must agree with; those answers are the session's source of truth.
WRITE THE ANSWERS — ROUTES.json: what each call should get back, including the failures.
STAND IT UP — `python3 scripts/dryrun.py serve ROUTES.json --port 8765`.

FIXTURES — `python3 scripts/dryrun.py fixture csv sample.csv --rows 20`.
SAY IT — a stand-in pass, and the first real run that will confirm it.
LEDGER — write the ledger line.

When it says no.

A test run against a live store or real customers.
Fake data that could pass as real.
A stand-in pass called a live pass.

ON EVERY DOOR · A CARD FOR YOUR AI, A FILE FOR YOUR COMPUTER

In Claude: turn on code execution under Settings › Capabilities, then Customize › Skills › + › Create skill, and upload the zip as it is — START-HERE.md in the box walks you through it, and tells you how to keep the ledger. In ChatGPT, Gemini and the rest: a Project, a GPT or a Gem with the card’s files attached and the short door in the box pasted as its instructions. The words run anywhere an AI reads Markdown; the machines run wherever the host runs Python. Witnessed in Claude only. The host marks →
