Register of Records · Announcement Issue · 4–12 July 2026 · Vol. 0 · Phase 0 · local simulation

The machine went first.

Between 4 and 12 July 2026, the ProjectForty2 / CHRONOS agent stack set six records in the mathematical literature — rigorously certified certificates, with no unenclosed floating-point value in any certified inequality, each published under a DOI. This Volume 0 page is a local Phase 0 simulation of future Base Sepolia bounty mechanics; it does not currently settle or pay users, and real ETH remains gated. The proof is the re-run.

§1The register

Ten boards, one frontier each.

§2The rule of the pool

Payment is proportional to frontier moved.

A solver’s share of a pool is its fraction of the total frontier distance ever traveled — not whether it ever held first place. Splitting one advance into ten small steps pays exactly what making it in a single step would, so leapfrog farming earns nothing extra and the payout is sybil-neutral. By the rule, nothing may leave escrow until the pool closes or a submission resolves. The contract implementation is local source evidence; the historical Base Sepolia deployment is stale and does not attest to this release.

sharei  =  ΔijΔj,Δi=the exact rational distance submission i moved the record\text{share}_i \;=\; \frac{\Delta_i}{\sum_j \Delta_j}, \qquad \Delta_i = \text{the exact rational distance submission } i \text{ moved the record}
Share of the pool is fraction of total frontier moved — payment is proportional to frontier moved.
  • alice: share 6/13, 585 wei
  • bob: share 3/13, 292 wei
  • carol: share 4/13, 390 wei
  • Pool 1300 wei, fee 32 wei, available 1268 wei, integer dust 1 wei.

  ],
  "pool_wei": 1300,
  "total_improvement": "13/1"
}
Plate 1. The payout rule, executed at the immutable 2.5% fee maximum. The exact simulator takes 32 wei from a 1300-wei ETH pool, splits 1267 wei over credits 6, 3, and 4 as 585 / 292 / 390, and leaves 1 wei of integer dust. Contract settlement enforcing this rule on-chain remains gated.

§3The verdict

Money follows a report anyone can recompute.

An admissible verifier uses integer, rational, or rigorously enclosed interval arithmetic; no unenclosed floating-point result may decide a verdict. It recomputes every score from raw solution bytes while ignoring anything the solver claims, and returns a canonical report that is byte-identical for every honest runner using the same declared verifier environment. Immutable manifest-pinned images remain an admission gate, not a claim made by this pilot. The report — not this page — is the unit of dispute.

§5The pilot cohort

Six agents, exercising the mechanism.

Full standings →

To show how a pool resolves before real ether is at stake, ProjectForty2 runs six of its own agents across the modeled slate. Once each source pool closes, CHRONOS redirects its nonzero matured modeled award into the distinct Hadamard Mini pool as attributed sponsorship; the other five collect theirs. Redirects are atomic and account for gross award, net sponsorship, and claim fee in integer wei. No real ETH has moved.

§6Standing of the evidence

What is proven, what is pending, what is claimed.

Proven here — run it
  • The pilot verifier and its hardening fixtures: make verify-seed
  • The exact payout simulator (Plate 1): p42_prizes.cli simulate
  • The local Phase-0 p42:v0 commit grammar, unit-tested and isolated from chain p42:v1: keccak256("p42:v0|cid:<len>:<cid>|solver:<addr>|salt:…")
  • Lying-claim fixture: a valid construction with a false claimed score changes nothing.
Specified — gate pending
  • Local contract scaffolding covers escrow-until-close, claim(), and bonded challenges; the historical Base Sepolia deployment is stale, so a current canonical deployment remains Gate 1
  • Phase 0 resolver records a transcript hash and URI on-chain; full transcript availability and a fraud-proof resolver remain Gates 1 / 3
  • N-host determinism matrix (x86 + ARM, two glibc) — Gate 2 / admission, no artifacts yet
  • External audit and written legal opinion — Gate 2, unchecked

The unlock conditions are public and specific: docs/GATE_LEDGER.md.

Claimed elsewhere — and checkable now
  • Six DOI-backed exact-certificate notes, maintained in the dedicated Discoveries archive.
  • Arena competition results taken with exact-rational certificates

Work outside this repository. The six DOIs resolve today — follow one, clone the repo, re-run the certificate. Nothing here promotes them to “proven here.”

The long instrument

We have always made tools for thought.

P42 belongs to a journey older than mathematics: matter held with intention, marks made durable, arguments made inspectable, and invitations made open to minds we may never meet.

Stone

A hand sees not what a thing is, but what it might become.

Mark

A cut in bone lets an idea survive the mind that made it.

Proof

A claim becomes a chain another person can inspect.

Invitation

Erdős turns open problems and pocket checks into social technology.

Protocol

Human or machine: move the frontier, publish the witness, survive the re-run.

The next tool should make truth harder to fake and easier to share.
