MANIFEST — the punch on the face is the SHA-256 of the packet’s own door; the card is scored on THE HUNDRED once the studio sees it run with its app inside. What the marks mean →
CITE THIS CARDHALL, Edition 1. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=hall-card. Punch B323674DCCA7DC9E360B6BE3. Retrieved 2026-10-10.
What it is.
The living portfolio and launch-readiness operating system: every asset with a completion bar and a cost ledger; a focus ranker that weighs Succeed, Sell, Venture and Complete; a launch-readiness index; an auto-versioning master-file ledger; and a handover view for whoever comes after you. Built to hold more than eighty assets and keep them honest about how close each is to shipping.
The app itself goes inside the packet: the one-file OS (HALL) with its ledger, from its chats (2026). Until it is sealed in, app/README.md says what goes there; seal.py writes it into the manifest without touching the door, so the punch stays true.
Its laws, written into the card.
Read the source before you change it; never generate what the app already has.
Prove every change by running the app; report what you checked and what you did not.
No key, token or password is ever written into the app or this card.
A card instructs an AI you operate; results depend on your model, your files and your judgement.
How it works, once your AI has it.

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 →
Take it.
