Public Branch-Law Pilot Gates for CHC-CBL

The CBL branch law separates an absorbed carrier budget into branch-resolved channels of the schematic form

\Pabs = \Pext + \Pled + \Psink,
\qquad
\etaext + \etaled + \etasink = 1,
\qquad
\eta_i = \frac{P_i}{\Pabs}.

This identity is exact only after a declared carrier family, interface family, calibration convention, and observation window have been fixed. A public-data pilot can test whether the branch-law algebra and estimator grammar can be evaluated on available data surfaces, but it cannot supply same-instance branch fractions unless the branches are measured or exported for the same sample, interface, geometry, wavelength or energy grid, and calibration window.

The present public-pilot record therefore uses a deliberately toned classification ladder: center

& Public branch-law pilot succeeds without empirical closure. \\ tabular center

The following overreads are excluded: same-instance empirical branch closure, sealed calibration-instance certificate, Maxwell replacement, QED replacement, universal detector closure, and post-hoc assignment of missing branch fractions.

The companion record uses three public reference surfaces. EKHI supplies a curated open database of optical and thermal radiative properties of solid materials, including emittance, reflectance, transmittance, and absorptance curves digitized from the TPRC Data Series [citation]. The refractiveindex.info dataset supplies an open-source optical-constants repository with YAML-based metadata and material records [citation]. NIST XCOM supplies photon cross sections for coherent and incoherent scattering, photoelectric absorption, pair production, and total attenuation coefficients for elements, compounds, and mixtures over the 1 keV--100 GeV range [citation].

The support summary identifies five public source surfaces for the CBL-VP0 companion record and three real XCOM tables in the XCOM lane. The public surfaces are used as public pilot inputs only. They are not treated as a same-instance interface-tomography dataset.

The public pilot is tied to the following source surfaces and diagnostic summaries. These entries state the public-source basis and diagnostic role of each lane. center adjustboxmax width=

The construction record is: public source surfaces are identified; source tables or curves are normalized under their declared conventions; the EKHI curve-surface, Fresnel predictor, XCOM component-fraction, and same-instance boundary gates are evaluated; the declared labels are assigned; and the non-claim boundary is checked. Public availability is summarized by supplementary public-source basis and result summaries. Large source tables remain external to the manuscript claim, and the public-pilot classification uses only the declared support summaries.

The R/T/A lane asks whether public radiative-property curves can be ingested into the branch-budget grammar. The acquired EKHI-side pilot curve is a nickel hemispherical total-emittance curve. It contains an emittance branch surface, but not a same-window reflectance, transmittance, and absorptance triple. The lane is therefore classified as

\boxed{\texttt{RTA-PARTIAL}}.

The classification is intentionally partial. A full same-window $R/T/A$TeXR/T/A budget gate would require, on the same sample and same measurement window,

R(\lambda)+T(\lambda)+A(\lambda)=1

within a declared tolerance and with a covariance or uncertainty object. The declared public surface does not supply that object.

The $n,k$TeXn,k lane is a deterministic predictor consistency check. For a normal-incidence interface with complex refractive index

\tilde n = n+ik,

the predictor computes

R = \left|\frac{\tilde n-1}{\tilde n+1}\right|^2.

Representative records from the refractiveindex.info archive are parsed and evaluated. The resulting lane classification is

\boxed{\texttt{CBL-NK-PREDICTOR-GATE-SATISFIED}}.

This is not empirical branch tomography. It confirms that public optical-constants records can be used to instantiate a deterministic branch predictor under a declared interface convention.

The XCOM lane reads component photon-interaction cross sections as branch-like terms. For a given energy $E$TeXE, let $\mu_j(E)$TeX\mu_j(E) denote tabulated component coefficients, such as coherent scattering, incoherent scattering, photoelectric absorption, and pair-production components when present. The normalized component fraction is

f_j(E)=\frac{\mu_j(E)}{\sum_k \mu_k(E)}.

A closure residual is computed by

\Delta(E)=\left|1-\sum_j f_j(E)\right|.

The evaluated public lane uses real NIST XCOM tables for C, Al, and SiO$_2$TeX_2. The resulting table contains 244 rows. The maximum absolute closure residual is

\max_E \Delta(E)=0.0007123287671233,

which is below the declared source-rounding-aware tolerance

\tau_{\rm XCOM}=0.001.

The classification is therefore

\boxed{\texttt{CBL-XCOM-BRANCH-PILOT-GATE-SATISFIED}}.

This lane is a photon-interaction branch-algebra pilot. It is not an interfacial branch-tomography experiment and does not assign CBL carrier branches to a same-instance device or detector.

The same-instance lane remains not-run. The declared public surface contains no manifest tying externalized, ledger/internal, and sink-like branches to the same sample, same incident carrier family, same geometry, same wavelength or energy grid, same calibration map, and same uncertainty or covariance object. Consequently,

\boxed{\texttt{CBL-SAME-INSTANCE-NOT-ADOPTED}}.

A future same-instance record would require at least:

- sample or interface identifier; - incident carrier or absorbed-power reference; - branch-resolved reflected, transmitted, emitted, internal, and sink-like readouts as appropriate; - common axis definitions and units; - calibration map and uncertainty or covariance object; - a declared pass/fail residual gate.

The combined public-pilot classification is

\boxed{\texttt{CBL-VP0-PUBLIC-PILOT-PARTIAL}}.

The label remains partial because the strongest empirical object, a same-instance branch-tomography manifest, is absent. The XCOM lane supplies bounded public branch-algebra support but does not change the same-instance status.

The result should be re-evaluated if any of the following occurs:

- an EKHI, refractiveindex.info, or XCOM public-source basis cannot be identified under the declared source-surface convention; - the XCOM component fractions fail the declared rounding-aware tolerance on the public real tables; - a full same-window $R/T/A$TeXR/T/A triple is added and fails closure; - a same-instance branch manifest is supplied, which would define a distinct same-instance empirical object rather than automatically change the existing public-pilot label; - any public wording reads the pilot as a same-instance empirical closure, a calibration-instance certificate, or a Maxwell/QED replacement.

CBL-VP0 establishes a reproducible public-data pilot for the branch-law grammar. The companion pilot acquires public radiative-property and optical-constants surfaces, evaluates an $n,k$TeXn,k Fresnel predictor, and converts real NIST XCOM component tables into normalized branch-fraction pilot boards. The XCOM lane reaches CBL-XCOM-BRANCH-PILOT-GATE-SATISFIED; the same-instance branch-tomography lane remains CBL-SAME-INSTANCE-NOT-ADOPTED. The correct combined classification is CBL-VP0-PUBLIC-PILOT-PARTIAL. No stronger empirical or foundational claim is assigned.

The companion source summary contains source summaries, EKHI and refractiveindex.info pilot outputs, XCOM parsed tables, XCOM branch-fraction tables, same-instance boundary checks, and the combined gate classification. External source surfaces remain attributed to their original providers.
