Macroscopic definiteness needs no observer: the standard GRW/CSL objective-collapse law (Λ = λN², λ = 1e-16 s⁻¹) makes a 1 µm dust grain definite in 2.8×10⁻⁸ s and a 6×10⁹ kg mass in 7.7×10⁻⁵⁸ s — far below any resolvable timescale, with no role for an observer.

PROVISIONAL definite in ≲10⁻⁸ s (1 µm grain) under GRW/CSL objective collapse — no observer required reproduced ≠ discovered re-run & confirmed 2026-07-09 (R0 — founder CI; independence pending)

CORRECTED 2026-07-26: the registered statement named Joos–Zeh environmental decoherence, but the script implements GRW/CSL objective collapse — a live, experimentally testable modification of quantum mechanics with a free parameter. The strings 'Joos' and 'Zeh' appear in no source file. The sub-Planck figure comes from the naive N² law the script itself labels pedagogical; its saturated bulk law gives 2.8×10⁻³¹ s, above the Planck time.

Falsify-box — how to kill this claim

UNTESTED The mechanism the script implements is GRW/CSL objective collapse, Lambda = lambda*N^2 with lambda = 1e-16 s^-1 (definiteness_seam/run_definiteness_seam.py:68), NOT Joos-Zeh environmental decoherence - the strings 'Joos' and 'Zeh' appear in no .py file in the repository. Kill test for the RESTATED (GRW/CSL) claim: at N = 1e8 amu and T = 1 s the script's own Panel-B law gives Lambda = 1e-16 * (1e8)^2 = 1.00 s^-1 and hence interference visibility V = exp(-1) = 0.368. The claim is DEAD if a levitated-nanosphere interferometer - the 1e8-1e10 amu band the script itself annotates 'NEXT levitated nanospheres', i.e. MAQRO-class levitated optomechanics - reports centre-of-mass fringe visibility V > 0.50 at N >= 1e8 amu with coherence time >= 1 s AND superposition separation Delta x > r_C = 1e-7 m (the CSL correlation length the script states at line 78), after subtracting known environmental decoherence. That bounds lambda < 0.69e-16 s^-1 and voids the quoted ladder. The separation condition is load-bearing: coherence preserved at Delta x << r_C does not bound lambda and must NOT count as a trip. Note N = 1e8 < N_cluster = 1e10, so no saturation applies in the discriminating regime and the naive N^2 law IS the honest prediction there. Separately DEAD if the recomputation fails: 1/collapse_rate_naive at N = 6.022e11 (1 um dust) departing from 2.76e-8 s, or at N = 3.613e36 (6e9 kg pyramid) from 7.66e-58 s, by more than 1%.

Status, honestly

CORRECTED 2026-07-26 by the kill-test sweep; the audit flag it carried is resolved. Status here is computed from evidence — the author cannot set it, and neither can we. Independent reproduction would move it; nothing else will.

§ Reproduction run_definiteness_seam.py

Two runs of the same script — mine, and one you can start right now. A match proves the result is reproducible; it is still R0 on this registry's independence rings — same code, so it cannot move a status. Only an outside run does that.

==========================================================================
THE DEFINITENESS SEAM — what actually makes the world definite
==========================================================================

  THREAD 1 — MASS, NOT MINDS. Objective collapse makes definiteness a real,
  observer-free event whose rate climbs as N^2. The everyday world isn't definite
  because someone looks; it is definite because it is too MASSIVE to stay
  superposed. A dust grain settles in ~10^-8 s, a pyramid in ~10^-57 s, with the
  desert empty. (Honest ceiling: this is a live, being-tested hypothesis, not a
  proven one — see ../participatory_seam. Many-Worlds, in which nothing collapses,
  is still standing.)

  THREAD 2 — MEASUREMENT ERASES INTERFERENCE. The other route to definiteness:
  the environment records which path was taken. Englert's V^2 + D^2 = 1 is
  substrate-independent, so the seismic double slit of ../pyramids_seismic is a
  which-path detector — the more the ground 'knows' which gap the wave used, the
  more the interference fan disappears. No quantum mechanics, no consciousness:
  just information in the rock.

  THE FUSION: 'the pyramids were observed and the Earth's superposition collapsed'
  becomes two honest, quantitative statements — mass makes big things definite,
  and measurement trades interference for which-path knowledge. The watcher was
  never needed. That is the real, deep bottom of the double slit.
