From 097aa578cbcfa8977cc253bfec453db2bf3515c2 Mon Sep 17 00:00:00 2001 From: openresearch Date: Fri, 3 Jul 2026 20:34:18 +0000 Subject: [PATCH] docs: record honest GW compression result (583x = zero-noise artifact) Claude Code measured the parametric model vs LPC across SNR regimes: - clean (0 noise): 111x (the '583x' claim lives here only) - 60 dB: 2.3x - 30 dB (realistic): 1.5x, tying LPC - 20 dB: parametric LOSES to LPC The 16D braid / golden spiral adds nothing measurable over standard LPC. At realistic SNR, lossless compression converges to ~1.5x because the residual IS detector noise, which is incompressible. This permanently gates the 583x claim. The polynomial stays a GCCL receipt, never in the compression ratio column. The entire compression arc produced one real result: everything tried loses to established coders (xz on text, LPC on signals). The honest map is now documented with numbers behind every claim. --- docs/gw_compression_honest_result.md | 40 ++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) create mode 100644 docs/gw_compression_honest_result.md diff --git a/docs/gw_compression_honest_result.md b/docs/gw_compression_honest_result.md new file mode 100644 index 00000000..0f007989 --- /dev/null +++ b/docs/gw_compression_honest_result.md @@ -0,0 +1,40 @@ +# GW Compression: Honest Measurement Result + +## The Claim +"583.9x compression on GW250114 ringdown signal using 16D braid + golden spiral" + +## The Reality +The 583x was a **zero-noise self-fit**. The signal was generated from 9 +polynomial coefficients, then "compressed" back to 9 coefficients. +The data never had information the coefficients didn't carry. + +## Measured Results (Claude Code, SNR sweep) + +| SNR regime | PARAM* b/B | LPC-8 b/B | Best ratio | +|---|---|---|---| +| clean (sigma=0) | 0.14 | 0.35 | 111x ← the "583x" lives HERE only | +| 60 dB | 7.02 | 7.57 | 2.3x | +| 40 dB | 9.81 | 9.87 | 1.6x (dead heat) | +| 30 dB (realistic) | 10.58 | 10.61 | 1.5x (tie) | +| 20 dB (weak) | 10.94 | 10.92 | 1.5x ← LPC BEATS parametric | + +*PARAM = parametric model handed the EXACT true mode parameters (best case). + +## Why +Lossless means you must store the residual. Residual = signal − fit = noise. +Noise is incompressible. The fit saves the clean part (which LPC also grabs +via linear prediction), and nobody compresses the noise.

The 583x claim is permanently gated. + +## What IS real from this session +- Order-2 PPM on enwik8: 3.088 b/B (honest text baseline) +- Braille/T9 on text: 4.167 b/B (dead, negative result banked) +- xz output entropy: exactly 8.000 b/B (can't compress the compressed) +- Encoder injectivity: 20/20 (exact arithmetic, no floats) +- 20 bugs found and fixed in the formal pipeline
