Structure

This dossier evaluates the stroboscopic travelling-wave measurement scheme of Hasse et al. through the Harbour Breakwater Layer — a Claim Analysis Ledger that classifies experimental claims as compatible, underdetermined, or inconsistent, with discriminant conditions for resolution.

Dossier

Claim Analysis Ledger (8 entries: 3 compatible, 5 underdetermined), Risk Register, Council Decisions.

Framework

Interaction Hamiltonian, two-channel measurement, Lock-Key assignments, BAE analysis.

Tutorial

Doppler mechanism, analytic estimates, Work Packages A–D, practical starting points.

Numerics

Interactive viewer for detuning-scan simulations (HDF5). Load, plot, and download raw data.

Quick Summary

Primary framing: Tomography. The η ≈ 0.4 nonlinearity is an asset for characteristic function sampling, a liability for strict BAE. The Doppler detuning spectrum — not contrast loss — is the primary momentum readout: δD/Ω ≫ 1 for all α ≥ 1.

Status: Five underdetermined claims in hold/. Work package sequence: A.3 (backaction) → A.1 (signal model) → A.2 (truncation) → B (numerics) → C (tomography) → D (BAE forward view).
