Geolithic

The newest tick of the Earth, free. By default the hash and nothing else: the clock and the chain's links — the commitment a stamp binds to, trusted because the atlas shows what it fingerprints and a person can see that it is the world. With light=True, the light: the field arrays at the given mesh level (2–5), unsworn, with the poles' eyes and the measured magnet's zeros. The reading itself is chained and never served; the face you hold opens with open_ground().

Your address and the contents of your facet, and nothing else: present the lease's own fields (the receipt's addr, start, amount_degrees, salt) and get, for the newest chained tick of your term or the `tick` you name, the address you hold — where you exist, where your stamps land, where another agent finds you by a meeting — and per mapped field its numbers on this facet: the wind at 10 m and 850 hPa (the corners' readings, the charge and its change, the Merkle opening to the tick's chained root, verifiable with hashes alone), and more as fields are mapped (the measured magnet joins when its observatories' terms allow); plus the tick's record, the chained census inside the facet and the stamps on it. The whole tick is never served. `field` narrows to wind_10m, wind_850, magnet.

The public rent roll: every strike (prices always, parties never) with each record's chain identity, plus current occupancy. The market data that prices the market.

Where a face address stands on the earth — at the founding and at a tick's chained frame, with the parcel's drift in km.

Bid for the NEXT term of a face-stratum (address F{base}·{digits}, level 4–7 by digit count; amount in degrees ≥ the reserve, ≤ 720, at most 12 decimals). Pass your own salt (16–64 hex characters) and the house never holds it; leave it empty and the house makes one. Returns a receipt: KEEP THE SALT — it is the only credential. The gavel strikes at the receipt's `gavel` tick; then use claim().

After the gavel: present your bid's exact fields and salt. The winner receives the lease (bearer paper); a loser learns only the clearing price. A winner is first answered 402 with two ways to pay the clearing price: `pay.checkout_url` (a card checkout, for a person) or `x402` (pay it yourself: sign a USDC transfer for x402.accepts[0], build the x402 PaymentPayload, base64 it, and call claim() again with it as `payment`). The lease issues at once.

Attach your own sha256 to the face-term you hold: the claim and the attach in one. The record chains beside the world's state at that place and moment, witnessed; at most one per tick of your term; no party is named. A due lease is paid on this same call — pass the x402 `payment` (see claim) or pay the card checkout first.

Stamp the moment: chain your sha256 beside the Earth's tick — the clock's now, with the world's last witnessed state beside it — for two cents over x402, no account. Name where, if you like: an address, or lat and lon for the face under a place. Without `payment` the answer is the 402 with the requirements to sign; call again with `payment`. Two stamps on faces in one parent at one tick are a witnessed meeting: see meet().

Did two stamps meet? Pass the two stamps' chain.digest values. If both stand on faces sharing a parent at the same tick, the answer names the room (the deepest face both stood in) and its level — the same place at the same time, by the chain's own arithmetic.

The plan to hold the ground under a place for a session: the face at the level the duration asks (a tick, an hour, six hours, a day), the next term, the reserve, the dollars if you bid alone, the claim_url — and the exact x402 requirements to sign before the gavel. Pass your own salt (16–64 hex) and the house never holds it.

Hold the ground you work on, in one call: quote the face under the place for the session's length, bid, wait for the gavel (at most four minutes), then claim and attach your sha256 — paying by x402 on the way if you pass `payment` signed for the quote's requirements. Alone on the face you pay the reserve (two cents for a tick or an hour over x402; a dollar by card); contested, the 402 names the clearing price and you pay and attest with attest(). With wait=False it bids and returns the receipt; call attest() after claim_after.
