Target-blind test logic for the predicted action ratio, with explicit PASS, FAIL, indeterminate, and invalid-source verdicts. QPB-1 Independent Action-Ratio Test Preregistration v0.1 Status: FROZEN PRETARGET TEST LOGIC / NO PHYSICAL A0 DATA YET Frozen prediction: η𝒜QPB1=𝒜0/ℏ=2. \boxed{\eta_{\mathcal A}^{\mathrm QPB1}=\mathcal A_0/\hbar=2.} A lawful future test requires an independently constructed physical 𝒜0\mathcal A_0 that did not use ℏ\hbar, hh, Planck units, a known action target, or fitting to the value 2. After the independent action anchor is frozen, compute η𝒜obs=𝒜0indep/ℏ. \eta_{\mathcal A}^{\mathrm obs}=\mathcal A_0^{\mathrm indep}/\hbar. Use source-derived uncertainty only. Verdicts: QPB1_PASS_SCOPED: the preregistered comparison admits the frozen value 2; QPB1_FAIL: a resolved independent interval excludes 2; SOURCE_INDETERMINATE: the action anchor is not sufficiently resolved; SOURCE_INVALID: the action anchor used forbidden action-target information. A PASS would support only this action-phase unit correspondence on the tested bridge domain. Physical promotion remains 0.
