We present a model-agnostic screening protocol for detecting recovery transients compatible with Bandwidth-Limited Quantum Control (BLQC)-style dynamics. BLQC, the finite-rate basis-tracking module of the Ignorant Observer Framework (IOF), motivates double-exponential visibility decay V(t) = exp(−(1/2) σ₀² e^(2κt)), which linearises as ln(−ln V) ∝ t. The protocol tests this against the power-law alternative ln(−ln V) ∝ ln t using a dual R² statistic. We apply the protocol to three precision-instrument platforms: Chinese 63-qubit processor cosmic-ray events, Google Sycamore qubit cosmic-ray recovery, and LIGO gravitational-wave detector glitches. The qubit platforms show power-law dominance (mean ΔR² = −0.21 for Chinese, −0.12 for Google; essentially no joint Gompertz-consistent population). On LIGO, a naive dual-R² comparison gives 88% of well-fit (R²_t ≥ 0.90) events preferring t-linear, but this figure is inflated by conditioning on the t-fit — under a selection-symmetric gate it falls to ≈50.7%. The load-bearing results are therefore the cross-platform asymmetry, which survives the symmetric gate (≈50.7% LIGO vs ≈0.4% Chinese), and the gate-free AICc model competition, which favours Gompertz in ≈56% of LIGO events (versus ≲5% on the qubit platforms) with internal rate-consistency c/2κ ≈ 0.91. A public H1 AUX_CLN cross-check finds no corrected-significant BLQC-positive vs. BLQC-negative label separation in available auxiliary channels; a controller-regime reanalysis finds that LIGO's fitted κ has a strong raw association with ASC recovery-stress ranks (Spearman ρ = 0.123, BH q ≈ 5.2 × 10⁻⁶), absorbed by morphology controls. This is a retrospective screening exercise and does not establish causal attribution to BLQC. Causal attribution requires the prospective controlled-capacity experiment specified in the BLQC paper — varying calibrated useful C_eff while holding ordinary thermal, readout, plant, timing, and alignment confounds fixed.

The Ignorant Observer Framework (IOF) predicts that information-processing constraints produce measurable signatures in physical systems when perturbations exceed controller capacity. We present forensic analysis of three independent experimental contexts: cosmic ray events in a Chinese 63-qubit superconducting processor (Li et al., 2025), cosmic ray impacts on Google's Sycamore processor (McEwen et al., 2022), and high-SNR glitches in LIGO gravitational wave detectors. Using a derivative-based classification protocol, we find that recovery dynamics partition into two distinct populations: (1) immediate exponential recovery consistent with standard control theory, and (2) delayed sigmoidal recover with initial plateaus consistent with IOF's "chaos-wins" regime where controller capacity is temporarily overwhelmed. The Chinese data establish a capacity-wins baseline with 100% exponential recovery at 5.6 μs resolution. Google Quantum AI data show 62% of events exhibiting delayed recovery signatures. LIGO glitch analysis reveals 57% of high-SNR events with extended recovery delays. While this retrospective analysis cannot constitute proof, the consistent pattern across platforms with different physics, timescales, and controller architectures suggests the IOF framework may capture genuine features of controlled quantum and classical systems under stress.
Bandwidth-Limited Quantum Control (BLQC) is the operational tier of the Ignorant Observer Framework (IOF): a finite-rate phase-reference control law and its benchmark. The object of study is not a modification of the Schrödinger equation, a derivation of the Born rule, or a solution to Bell's theorem. It is a narrower control question: if the phase or basis reference θ(t) is maintained by a finite-rate tracking loop, does the observer-relative loss of online visibility scale with the deficit between the reference dynamics and the tracking channel? In a minimal phase-reference model, an unstable reference mode with instability rate h_KS tracked through an effective channel of rate C_eff predicts V(t) = exp[−(1/2) σ₀² e^(2κt)], with κ = h_KS − C_eff ln 2. The primary observable is the breakdown time t_break ∝ 1/(h_KS − C_eff ln 2) under deliberate throttling of the effective basis-tracking channel. Crucially this is reference-frame physics within standard quantum mechanics: standard quantum mechanics plus the classical Data-Rate Theorem already predict it, and the lost contrast is recoverable once the missing reference information is supplied. The benchmark is therefore expected — it calibrates the reference channel rather than discriminating IOF from quantum mechanics. A residual, capacity-scaled loss below the shadow-log prediction would be the one reading that is new physics; it is excluded by existing recoverability experiments and survives only as a registered test for certified deterministic-chaotic reference dynamics, with the prior strongly against it. The mesoscopic regime is the scientific target because the same finite-rate timescale can overlap with Penrose objective-reduction timescales while depending on different knobs — tracking bandwidth rather than mass geometry. The calibrated reference channel and the recoverability classifier defined here are what the companion Experimental Protocol uses to discriminate Penrose objective reduction from standard physics. We specify the assumptions, operational estimators, calibration rules, and decision rules.

This document specifies a single prospective experiment: a mesoscopic visibility-loss test that discriminates Penrose objective reduction (OR) from standard physics, in the regime where OR's mass-geometry timescale and the framework's finite-rate basis-tracking timescale fall in the same window. Penrose OR assigns an unrecoverable, mass-geometry-dependent loss; the basis-reference channel of Bandwidth-Limited Quantum Control (BLQC) produces a capacity-dependent but recoverable loss, κ = h_KS − C_eff ln 2 — reference-frame physics within standard quantum mechanics, not a rival prediction. The design's distinctive feature is that the reference channel is calibrated and frozen in advance, and that recoverability (from a passive shadow log) classifies each contrast loss as observer-relative reference bookkeeping (recoverable, R_rec ≈ 1) or collapse-type (unrecoverable, R_rec ≈ 0, mass-geometry-tracking, persistent at maximal tracking capacity). Because the reference physics is measured rather than estimated, it becomes the experiment's calibration arm — the subtrahend — rather than a nuisance background. The core question is then sharp: at fixed thermal, readout, pulse, latency, and plant conditions, is there a κ-independent, unrecoverable visibility floor that follows mass geometry? A positive result is evidence for Penrose OR; a null becomes a quantitative bound on OR rather than an inconclusive absence. The discrimination is of OR against standard physics, not of the framework against quantum mechanics — the framework predicts no floor of its own and cannot win the test, only make it decidable. The protocol defines the platform, control variables, confound controls, statistical tests, and decision rules.

A conditional derivation of the binary Born probability form p(θ) = cos²(θ/2) in the physical basis coordinate θ of a Bandwidth-Limited Quantum Control (BLQC) experiment, within the Ignorant Observer Framework (IOF). The derivation rests on two load-bearing bridge assumptions: that BLQC effective tracking capacity C_eff is capacity for preserving operational distinguishability of finite observer records (the Fisher capacity bridge), and that the scalar BLQC threshold κ = h_KS − C_eff ln 2 is homogeneous in the physical basis coordinate (scalar-threshold homogeneity). Under the Fisher capacity bridge plus standard finite-resolution invariance, Cencov's theorem selects Fisher–Rao as the unique distinguishability metric on observer records; the binary record then carries the Fisher-arclength identity p(s) = cos²(s/2) by elementary geometry. Scalar-threshold homogeneity forces equal increments of θ to carry equal Fisher cost, so the Fisher arclength coordinate is affine in the physical basis coordinate; endpoint calibrations p(0) = 1 and p(π) = 0 then fix p(θ) = cos²(θ/2). The result is conditional on both bridge assumptions. Neither the bridge nor the full Hilbert-space formalism of quantum mechanics is derived here. The paper supersedes an earlier conditional derivation that obtained the binary Born form only in Fisher arclength and deferred the identification of that arclength with the laboratory basis angle; the BLQC bridge here is that deferred step, folded back into the original derivation as a single coherent argument.

Companion document to Bandwidth-Limited Quantum Control (BLQC) within the Ignorant Observer Framework (IOF). It states the conceptual claim that BLQC's experimental discriminator operationalizes: that the measurement basis is not an externally supplied free parameter but a physical variable with causal ancestry inside the same history as the measured system. The ontology is explicitly hosted: a no-collapse embedding (pilot-wave or Everett-type) supplies the Born weights and the standard quantum correlations, and IOF contributes only a single capacity-dependent visibility attenuation on top. The Born rule and Bell's theorem are not derived; the falsifiable handle is the BLQC capacity-instability scaling. The position on Bell is measurement dependence in the technical, non-conspiratorial sense defended by Palmer, distinguished from a completed deterministic theory of the 't Hooft type. Three standard objections are addressed in order: that the move merely relocates the mystery, that the predicted visibility loss is just correctable reference noise, and that the framework reduces measurement to control engineering. The paper relocates the Heisenberg cut from interpretive convention to an operational boundary set by the apparatus's finite basis-tracking budget, with the Landauer bound entering only as a thermodynamic ceiling, not as the operative rate.

A timing signature is not physics until its reference operator survives a representation audit. CV⋆=FR2,UT⋆=1−FR2,CV⋆+UT⋆=1 This framework separates three objects that must not be merged: a completed historical event, the record support still accessible to a laboratory, and a separately calibrated timing observable. Standard quantum theory closes the optimized coherent-recovery envelope. QTT adds a distinct, falsifiable timing complement only after a physical intertwining certificate proves that the laboratory record operator and the central timing projector are the same physical object in two representations. A public 11,009-trace test of explanatory burden Version 1.4 executes the complete usable public archive associated with Gosling et al., Probing the memory of a superconducting qubit environment. Every trace is split chronologically into training, a discarded guard interval, and held-out testing. The ordinary one-TLS Solomon camera learns two rates per trace, while the memoryless comparator learns one. median(RMSE0RMSE0−RMSETLS)=0.36015,P(TLSwins)=11,00910,169=0.92370 The fitted TLS camera is therefore a successful held-out effective model. Its resolved trajectory is not a parameter-free derivation: the values of Γq and Γqt are learned from each target-bearing trace's training segment. Version 1.4 makes that distinction machine-auditable through the target-fit burden vector BM=(Nc,Nd,Nw,Nn,Nu,Nh),BM=0⟹the fitted output is not derived parameter-free. The QTT result A public QTT source statement from 12 November 2025, before the Gosling preprint, already required complete reset to erase distributed record support beyond the visible carrier. That statement contains no Gosling-fitted rate, hidden-mode count, target window, or trajectory coefficient. The resulting comparative verdict is QTT-ZERO-FIT-SOURCE-EXPLANATORY-VICTORY/TRAJECTORY-VERDICT-OPEN. This is a scientific victory at the source/ontology layer, not a claim that QTT has already predicted the same resolved qubit trajectory. The stronger same-observable verdict remains locked because the public archive does not independently provide the residual record fidelity Fres, leakage diagnostic D, timing complement UT, or physical intertwiner W. The paper prints the exact next experiment that would close or falsify that bridge. Reproducibility 11,009 row-level held-out results are included. The 840 traces favoring or tying the memoryless camera are retained. No false significance is assigned to correlated sweep windows. All three official archive objects pass their published MD5 checks. The release verifier passes 30/30 scientific and provenance checks. Three adversarial reviews cover observable equality, leakage and selection, chronology, and claim scope.
