THE READING SHELF — the LSC-1 face
THE CARD AS TEXT · FOR EYES AND FOR MACHINES

THE READING SHELF · books served to an AI by retrieval

WAKES WHEN someone wants an AI to answer from their own books and say where the answer came from

THE LOOP

  1. index <folder> · the shelf and its map
  2. ask "<question>" · passages, cited
  3. read the passages; quote with the citation
  4. cite <book> <n> · one passage whole
  5. nothing found: say so; never from memory

NEVER

  • Answer from memory when the shelf is silent
  • Quote without the book and the passage
  • Send a book anywhere

IT MAKES index — every .md and .txt in the folder is a book; the passages and the map written; ask — the passages that carry the question's words, scored, each cited book · passage; cite — one passage whole, with its citation, to quote from; map — the shelf: every book, its passages, its size.

THE STANDARD retrieval, not training; every answer is cited; silence is an answer; passages stop at paragraph edges; the map is public to its owner; the books stay where they are.

CITE THIS CARDTHE READING SHELF, Edition 1. Lund Studio LLC, Westminster, Colorado. https://lundr.tech/?view=reading-shelf-card. Punch B42B4CAC0893E68A1D471E4C. Retrieved 2026-10-10.

What it is.

Serves a shelf of books to an AI by retrieval instead of training: index cuts every .md and .txt in a folder into passages at paragraph edges and writes the shelf and its map; ask scores the passages that carry a question's words and returns the best few, each cited book and passage, with the words that matched; cite returns one passage whole to quote from; map lists every book with its passages and size. Nothing is learned from the books and nothing leaves the computer.

It carries a machine that shows its working: index — every .md and .txt in the folder is a book; the passages and the map written; ask — the passages that carry the question's words, scored, each cited book · passage; cite — one passage whole, with its citation, to quote from; map — the shelf: every book, its passages, its size — 12 checks in its selftest, every command on the record. It will never answer from memory when the shelf is silent; never quote without the book and the passage; never send a book anywhere.

Six laws, written into the card.

They are in the card itself, so the AI follows them.

RETRIEVAL, NOT TRAININGThe books are cut and indexed; nothing is learned from them, and the model is the same after as before.
EVERY ANSWER IS CITEDBook and passage — or it is not an answer from the shelf.
SILENCE IS AN ANSWERWhen no passage carries the question's words the card says so, and the AI must not fill the gap from memory.
PASSAGES STOP AT PARAGRAPH EDGESPassages stop at paragraph edges, so a quote is never cut mid-sentence; a long paragraph stands whole.
THE MAP IS PUBLIC TO ITS OWNEREvery book, its file, its passages, its size, written beside the shelf.
THE BOOKS STAY WHERE THEY AREThe shelf is a file beside them; nothing is copied anywhere else and nothing is sent.

What rides in the card.

In the card’s own voice, with a machine that shows its working.

THE GUIDEreferences/WHY-RETRIEVAL.md
THE MACHINEshelve.py · four commandsindex — every .md and .txt in the folder is a book; the passages and the map written; ask — the passages that carry the question's words, scored, each cited book · passage; cite — one passage whole, with its citation, to quote from; map — the shelf: every book, its passages, its size. Every command prints its working and refuses a bad input; 12 checks in its selftest, every command on the record.

What it does once your AI has it.

  • index Every .md and .txt in the folder is a book; the passages and the map written
  • ask The passages that carry the question's words, scored, each cited book · passage
  • cite One passage whole, with its citation, to quote from
  • map The shelf: every book, its passages, its size
  • On the record Two books shelved and mapped; a question found the tide passage and cited it; one passage returned whole to quote from; a question with no words on the shelf was answered with silence, named as such.

What it will never do.

It will never answer from memory when the shelf is silent; never quote without the book and the passage; never send a book anywhere.

The shelf matches words, weighted by how rare they are on the shelf; a question in other words than the book's can miss, and a passage that carries the words can still not answer. The AI reads what comes back and says what it says; the card does not understand the books. Plain text only: a PDF or a Word file is a book once its words are in a .md or .txt. It is an AI reading a text file: it can be wrong, so check what matters against your own records and the source.

What’s in the buy.

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 1086 PROPOSED — LAUNCHING SOON

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 medical, legal, tax or financial advice, never the person’s boss, and not a licence to practise. 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.

A TERM, NOT A SUBSCRIPTION: NOTHING RENEWS ITSELF AND NOBODY IS CHARGED AGAIN. WHEN A TERM ENDS THE FILES STAY ON YOUR COMPUTER AND STAY READABLE — FREEZE, NOT LOSS.

THE MACHINE · IN THE OPEN · FROM THE WITNESSED RUN OF 2026-10-10

shelve.py, every command showing its working.

A small Python program, standard library only. Your AI runs it; you can too. Every block below is pasted from the card’s own WITNESS.md, as printed.

THE NUMBERS, NAMES AND DATES IN THESE RUNS ARE THE STUDIO’S OWN EXAMPLES, INVENTED FOR THE RECORD; NO REAL COMPANY, PERSON OR PROPERTY IS NAMED.

QUESTIONS AT THE TABLE

Asked before the wire.

What does it need from me?

Index <folder> · the shelf and its map. It asks first for the folder of books, and the question.

Does it send anything anywhere?

No. The machine is a standard-library Python program that runs on your own computer and sends nothing anywhere; the words run wherever an AI reads Markdown. No server, no account, no key.

What is on the record?

The self-test (12/12) and every command run on real example inputs, pasted into WITNESS.md as they printed; the punch on the face is the SHA-256 of SKILL.md, so a downloaded copy can be checked against this room.

Can it be wrong?

Yes — it is an AI reading a text file. The shelf matches words, weighted by how rare they are on the shelf; a question in other words than the book's can miss, and a passage that carries the words can still not answer. The AI reads what comes back and says what it says; the card does not understand the books. Plain text only: a PDF or a Word file is a book once its words are in a .md or .txt.

What will it never do?

It will never answer from memory when the shelf is silent; never quote without the book and the passage; never send a book anywhere.
