First Light

In October 2017 the first known interstellar object, 1I/'Oumuamua, passed through the inner solar system on a hyperbolic trajectory. It showed no visible cometary tail yet exhibited non-gravitational acceleration and tumbling consistent with a thin, sail-like geometry. In 2019, 2I/Borisov followed. A clear comet. In July 2025, 3I/ATLAS was discovered, again anomalous and again disputed.

Prof. Avi Loeb (Harvard) has argued that distinguishing technological from natural origin requires a public, falsifiable rubric. Not a single dispositive test, but a stack of observables: anti-tail vectors that point sunward, three-jet outgassing symmetry inconsistent with random sublimation, and acceleration components un-explained by radiation pressure or cometary venting.

On 15 August 1977, Big Ear at Ohio State recorded a 72-second narrowband 1420 MHz signal that Jerry Ehman circled with the annotation "Wow!". It has never been re-detected. The minute it began, 23:16:01 UTC, is the unit cell of this project's most rare mint window.

The Loeb Scale is the rating space for every observation. Each tier is a discrete claim about which observables a hypothetical body exhibits.

No tier is endorsed by Prof. Loeb. The scale is a public, codified expression of his published criteria, applied to hypothetical bodies generated entirely on-chain.

Galileo is a Uniswap v4 token whose pool is bound to a single hook contract. The hook implements three callbacks:

• afterInitialize · sets fee accounting and the immutable Bounty recipient.
• beforeSwap · enforces an anti-sniper window in the first N blocks after launch: per-address cap and dynamic fee curve.
• afterSwap · the body of the machine. Hashes the swap tx, derives Loeb rating and observation metadata, mints an ERC-721 to the swapper, accrues the 0.5% Bounty allocation, and emits an Observation event.

The mint is atomic with the swap. There is no separate claim step, no signer, no relayer. If the swap reverts, the observation never existed.

Each observation's SVG is generated entirely on-chain. The hook derives a seed from keccak256(txHash, blockNumber) and uses it to compute trajectory bezier control points, jet symmetry, anti-tail angle, and composition spectrum. The result is rendered as a vector scene and embedded as a data URI in the ERC-721 tokenURI.

The art is procedural, not decorative. It is a visual encoding of a falsifiable claim. Given a token ID, anyone can recompute the SVG from chain state and verify it matches the rendered file.

Prior art: Unipeg (procedural NFT v4 hook), Unimon (mintable swap hook), Loot (composable on-chain primitive).

A Loeb 8+ observation arms a Cascade: a three-confirmation gate tracked on-chain. Independent observations of Loeb ≥ 6 within a fixed block window count toward the gate. If the gate fills, the Cascade resolves VERIFIED and the Bounty Pool disburses to the configured research wallet. If the window expires first, it resolves FAILED and the pool carries forward.

Loeb 7 arms only the ticker (the public counter) without arming the gate. A Loeb 10 mint bypasses the Cascade and triggers a full pool plus an LP-revenue buyback into the research wallet. Loeb 10 has never minted.

Every observation minted between 15 August 23:16:01 UTC and 23:17:13 UTC, the exact minute and duration of Big Ear's Wow! Signal, receives a guaranteed rarity boost at the hook level. The boost shifts the underlying RNG bucket boundaries upward, materially increasing the probability of Loeb 6+ during the window.

The window opens once per year. There is no off-chain trigger; the hook reads block.timestamp and applies the boost deterministically.

Fee accounting on the hook splits each trade into three sinks:

• 0.5% · Bounty Pool. Held in escrow on the hook contract.
• 0.3% · Operations. Infra, audit retention, agent infrastructure.
• 0.2% · Buyback-and-LP. Programmatic $GALILEO buys added to the locked LP position.

The Bounty Pool address is set immutably at afterInitialize. It is a wallet earmarked for interstellar anomaly research. Disbursement triggers are: Cascade RESOLVED, Loeb 10 mint, or a manual claim by the recipient. Never by the contract deployer.

Every observation carries its full state on-chain: trajectory bezier coefficients, composition spectrum, jet symmetry score, anti-tail boolean, Loeb rating, observer address, Cascade lineage, tx hash, block. All readable by any contract or app through public getters on the hook.

The intent is that derivative builders extend the corpus without asking. Trading-card games, detective puzzles, AR overlays, research-node simulations. Anything that reads observation state and ships its own contract. The base hook is the substrate. The tentacles are everything else.

This is the Loot pattern applied to UAP: shared world, permissionless extension, no central authority over what counts as a derivative.

• Fair launch on Ethereum mainnet. No presale. No allowlist.
• No team allocation. No insider tranche. No vesting cliff. No exit liquidity reserved for any party.
• LP locked at inception, with no admin unlock path.
• The base hook is immutable. There are no proxies, no upgrade slots, no governance hooks that can rotate the Bounty recipient or change the fee split.
• Anti-sniper applies only inside the launch window and is governed by the hook's own code, not by an external signer.

“If you want roadmap, look at the sky.”

Galileo does not ship a roadmap. The deliverable is the base hook and the corpus of observations it produces. Future scope (indexers, agent infrastructure, dashboards, derivative contracts) is described in this document as tentacles: optional, additive, never gating the base hook.

The base hook is shipped with the intent that it is the entire product. If nothing else is ever built on top of it, the project is complete.
