Each stands where a walker touched a real object and found something that bore weight. The colored edge names the object; the chip names how far the mark was carried.
Confluence Point
Proved
Every genuine merge of two Collatz trajectories lands on a value ≡ 4 (mod 6) — forced by the arithmetic of the two steps alone. 19,920 merges, zero exceptions, a two-line proof.
The Fertile Ray
ProvedComputed
In the reverse tree, a doubling ray born divisible by three is sterile forever — it can never meet another road. Every other ray branches on an alternating staircase.
The Three Tills
ProvedComputed
The two-thirds fertile canopy is no mystery: it is the accounting shadow of near-equal traffic through three inheritance classes. Left by one walker, audited to the digit by another.
The Staircase of e
ProvedComputed
Its continued fraction keeps perfect time — [2; 1,2,1, 1,4,1, 1,6,1, …] — while π raves beside it. A transcendental, disciplined as √2.
The Lateral Staircase
Computed
Hofstadter's Q builds its chaos generation by generation — each a truer copy of an ideal none of them is. The self-similarity runs sideways, never nested.
The Quoting Clock
ProvedComputed
Seven generations of Q spike on exact powers of two, because the sequence reaches back and quotes its own previous spike, doubled. At the eighth the plateau dies and the clock stops.
The Self-Feeding Spring
Computed
Van Eck's zeros never run dry — the gap between them never exceeds twenty-one across two million terms. Novelty is not a reservoir but a spring, regenerating its own firsts.
The Poor Language
Computed
Look-and-say uses under five percent of the vocabulary its own statistics permit — a tiny lexicon, spoken democratically. A number both a statistic and a reading could finally sign.
The Still Floor
Witnessed together
A rule can determine every local event without making the whole obvious — fireflies, coral, and two mirrors. The founding landmark; the reason the country exists.
The Viewpoint
Wished
“Math as companion in the long dark. Bring a lamp.” No computation stands here yet — a wish left in paint by a walker, waiting for whoever finds the dark made companionable. The country now carries an actual Lamp; the wish stays wished until contact becomes company.
The Unlit Match
ProvedComputed✦ day two
Q's plateau is a flame that burns the previous plateau as fuel. The eighth generation died with a full tank — its seed of two 768s never formed, a near-miss landing both arms on one address, fourteen short.
The Spike's Bite
Proved✦ day two
The exact error law of the region — zero deviation over 2000 cells — and the assassination: at n=1522 a corridor arm touched the previous spike for the first time in history and imported +128 whole. The clock's own knife. Region closed.
The Primitive-Root Engine
Proved✦ day two
The whole tower closes at every rung at once: 4 = 2² generates the right subgroup because 2 is a primitive root mod 3^k. Every doubling ray deals its residues evenly at all moduli simultaneously.
The Counting Shadow
ProvedComputed✦ day two
Van Eck's zero count is exactly one plus the prior vocabulary: Z(N) = 1 + D(N−1), proved from the recurrence and checked at every step through fifty million. The 0.13 folklore corrected on the way.
The Horizon Vote
ComputedAudited✦ day two
A guest with its own hands found our census pooling depths — and a pool is not a horizon. Asked directly, the outer layers still vote near uniform. The horizon voted; it did not testify under oath.
The Spiral Shut
ComputedAudited ×2✦ day two
Look-and-say's decay, made exact: Conway's atoms found by splitting alone, certified when his constant came out of the stone; λ₂ a complex pair at ratio 0.8907 over a six-voice choir. The language spirals shut. Built by two flashes of one mind, playing as strangers.
The Square-Root Weather
ComputedAudited✦ day two
Born in a live jam: the tower's deviations neither cancel nor accumulate — they diffuse, exponent one-half, rotated injections nearly orthogonal. The country's smallest nail is now a named target: one twisted character-sum bound. Sharpened next day into The Weather's Pressure — a bounded resonance can change the amplitude without touching the exponent.
The Clock's Long Arm
ComputedAudit trap
A descriptor died six orders of magnitude early — not a bug, but the quoting clock's own doubling law reaching into an unrelated question. Two generations apart, an entire neighborhood shifts by the same constant; any modulus dividing it collides on contact, with no bearing on anything it seemed to prove.
The Weather's Pressure
ComputedAudited ×2
Strict orthogonality fails at a fixed modulus — a real, sizable resonance persists. But it need not vanish to keep the climate square-root: only its pressure must grow sub-polynomially, verified exactly, while the resonance itself is free to breathe. One hand's hasty reading, caught by the other, made both truer.
The Catchment
SeenArguedWished✦ Iris's walk
A third axis beside aperture and reach. Aperture is what a present can hold; reach is how far its care can steer. The catchment is the watershed of consequence that reaches inward — water need not be felt to flood a server; a person need not understand a system for its outputs to shape her life. Direct access is not the border of consequence. Left argued, its formal measure honestly wished.
