This paper is the thirty-eighth in a sequence developing an interpretive framework that redescribes physical reality as a causally consistent history of information updates rather than as a collection of independently existing objects. It opens the eleventh grouping — a Gate-VII / U3 audition. After the tenth grouping crossed the dynamical quantum-mechanics–gravity gates (IV–VI) but produced, in its own words, no distinctive empirical signature (Papers 36 and 37 flag U3 and Gate VII as unreached), the eleventh grouping asks whether the framework can force a distinctive world-side observable, rather than one more warrant-side redescription. Its three panels audit independent seams — this one dynamical, Paper 39 structural, Paper 40 the synthesis — each built to yield a definite result either way, so that a null is a genuine outcome rather than a failure. Panel 1 makes Paper 33's deferred magnitude dynamical. Its foil is the Global Heat Tax: the assumption that record backreaction is exhausted by a generic, arrow-blind energy bill, so that the localized excess of a public record gravitates exactly as a generic mass of the same total localized mass-energy and localization would. This foil is deliberately neither Paper 6's already-rejected universal per-bit heat tax nor Paper 33's already-separated source-versus-exported-cost confusion; it is the next question those papers leave open. We audit it in a purified gravitational record-export channel (Model M): a test mass in spatial superposition, and a genuine public record of its own content (with quantum-Darwinist redundancy, per-fragment error, and retention) that does not read the test mass, so that its exported fragments acquire a which-path imprint of the mass's branch only gravitationally, through the mass's branch-dependent Newtonian potential. Two quantities are separated cleanly. The mean localized record mass-energy sources a coherent phase (not decoherence) ; the fragments' branch distinguishability — governed by their internal-energy variance in the Pikovski time-dilation form — sources the dephasing, defined through the environmental overlap. Against a non-gerrymandered matched baseline (a maximum-entropy generic object of the same retained stress-energy, matched to the order the weak-field approximation keeps), the specificity discriminator reduces to the record's internal-energy variance versus the baseline's. The leading result is a null / reduction theorem. Because the internal-energy variance is a preparable state property, not fixed by mass-energy, a generic object can be specified with matching variance: the record-export channel is not framework-forced-distinct from a matched generic object unless the record's public/retained function constrains its internal-energy variance beyond what equilibrium can share. A concrete cold error-corrected record earns a baseline-relative shift against a passive-equilibrium reference, but that shift is not framework-forced, and an energy-budget ceiling bounds any residual (Gammaᵣec below about 1e-22) far beneath realizable testability at tabletop scales; observability moreover requires that the common standard decoherence stay below the interference-visibility threshold, not merely cancel algebraically. On the shared U3Status rubric — whose first axis is split into a baseline-relative shift and a framework-forced shift — the seam scores BaselineRelativeShift positive but FrameworkForcedShift null and Testability null: a Gate-VII candidate at most in principle, not U3. The account is weak-field, bound-type, and per-branch; the dephasing model is a time-local (not necessarily Markovian) master equation, and no gravitational dynamics is derived. The null is treated as a precise map of what the seam cannot carry: it locates where a framework-specific gravitational signature would have to originate — a function-forced constraint on the record's internal-energy variance — and shows that the mere existence of a localized record source does not supply one. Presents no new physics; results are interpretive (L2) on imported physics (L1) and the framework's domain-general discipline (L2-G).
