THE STATE CARD · where the app keeps what it knows

WAKES WHEN an app must survive a viewer that denies storage; my artifact goes blank in the sandbox; find every unguarded localStorage call

  2. ASK — the app folder.
  3. LIST — every storage call by file and line.
  4. WRAP — every unguarded call, or keep that state in memory.
  5. TEST — in the viewer that denies storage.
  6. LEDGER — write the ledger line.

NEVER

  • a database chosen for you
  • an unguarded call passed
  • data migrated

CITE THIS CARDTHE STATE CARD, Edition 2. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=state-card. Punch CB67E64EAE65DBB813A420E9. Retrieved 2026-10-10.

What it is.

Every call to browser storage — localStorage, sessionStorage, IndexedDB, cookies, the Cache API — listed by file and line, and whether it is guarded: inside a try, or behind a feature test.

A sandboxed viewer throws on the first unguarded call and the app goes blank; this finds that call first.

Its laws, written into the card.

  • Every storage call is listed, guarded or not.
  • Guarded means a try or a feature test near it; the card says that is a reading.
  • One unguarded call fails the check.

How it works, once your AI has it.

  1. NAME — `This is THE STATE CARD.`
  2. ASK — the app folder.
  3. LIST — every storage call by file and line.
  4. WRAP — every unguarded call, or keep that state in memory.
  5. TEST — in the viewer that denies storage.
  6. LEDGER — write the ledger line.

When it says no.

  • Choosing or setting up a database.
  • Migrating data.
  • Calling a call guarded because it has never thrown yet → THE MONOLITH CARD splits the same file for the work.

What’s in the buy.

  • CARD.md — the whole card · SKILL.md — the door your AI reads first · START-HERE.md — the first five minutes
  • references/THE-METHOD.md · EVALS.json · EVALS.md · scripts/evals.py — the method, its template, and the tests with their runner
  • MY-LEDGER.md · TIN.md · LICENSE-NOTE.md · THE-CLAUSES.md · card.svg + card-machine.svg + card.json · card.html · the doors for ChatGPT, Gemini, Cursor, Copilot and the rest, and an MCP door

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.

Nº 688 PROPOSED · ONE PAYMENT

Sold as is under the term printed. A card instructs an AI you operate; results depend on your model, your files and your judgement. Not legal, tax, medical or financial advice. The terms →

ONE PAYMENT · NOTHING RENEWS ITSELF

OFFLINE · ONE LICENCE · PUNCH-CHECKABLE · THE STANDARD

One payment. The file is yours to keep and keeps working at its edition; new editions issued in the year after you buy reach you by email as replacement files. Tax is added at checkout where it applies. Nothing auto-renews.

One email when it is on sale, from the studio; nothing else, ever.

ONE PAYMENT — NOTHING RENEWS ITSELF. CHECKOUT IS SHOPIFY’S OWN; YOUR CARD COMES BY EMAIL AFTER IT.
