What it is.
Works out orbits by Kepler's laws with Newton's gravity behind them: period gives the time round from an orbit's size; axis gives the size from the time, so one sidereal day round the Earth gives the geostationary orbit; where solves Kepler's equation for where a body is on its ellipse at any moment; planets sets the planets' periods worked out from their distances beside the measured ones.
It carries a machine that shows its working: period — the time round; axis — the size for that time; where — the place on the ellipse; planets — the planets, worked and measured — 8 checks in its selftest, every command on the record. It will never solve an open orbit as an ellipse; never ignore the other planets unsaid; never confuse sidereal and solar days. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.
Six laws, written into the card.
They are in the card itself, so the AI follows them.
MEASURED GMThe Sun's, Earth's, the Moon's and Jupiter's GM are known far better than G or the masses alone; the card uses them.
SIDEREAL, NOT SOLARThe geostationary orbit matches the sidereal day, 23 h 56 min 4 s.
KEPLER'S EQUATION, SOLVEDM = E − e sin E, solved to 10⁻¹³ by Newton's method.
TWO BODIESThe outer planets drift from the worked-out years because each pulls on the others; the card says so.
ELLIPSES ONLYe ≥ 1 is an open orbit and is refused.
CHECKED AGAINST THE SKYThe inner planets' years match the measured ones within 0.2%.
What rides in the card.
In the card’s own voice, with a machine that shows its working.

THE MACHINEkepler.py · four commandsperiod — the time round; axis — the size for that time; where — the place on the ellipse; planets — the planets, worked and measured. Every command prints its working and refuses a bad input; 8 checks in its selftest, every command on the record.

On the record One au round the Sun takes 365.26 days; one sidereal day round the Earth is the geostationary orbit at 42,164 km; a comet of e = 0.967 placed on its ellipse; the planets worked against measured.
What it will never do.
It will never solve an open orbit as an ellipse; never ignore the other planets unsaid; never confuse sidereal and solar days. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.
Two-body orbits: no drag, no perturbations, no relativity (Mercury's perihelion moves 43″ a century more than this predicts). It is an AI reading a text file: it can be wrong, so check what matters against your own records and the source.

Nº 1130 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. 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.
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.

QUESTIONS AT THE TABLE
Asked before the wire.
What does it need from me?
Period <a> · the time round. It asks first for the orbit's size or period with units, and what it goes round; or e and the mean anomaly.
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 (8/8) 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. Two-body orbits: no drag, no perturbations, no relativity (Mercury's perihelion moves 43″ a century more than this predicts).
What will it never do?
It will never solve an open orbit as an ellipse; never ignore the other planets unsaid; never confuse sidereal and solar days. It never helps design, make, grow, enhance or spread a pathogen or toxin, or plan work meant to harm.
