Scientific claims often fail in the crossing between two otherwise valid descriptions. Boundary-State Calculus (BSC) treats that crossing as a typed, inspectable, and falsifiable object.
BSC audits one claimed transfer: what moves, what is lost, what still satisfies the target equations, what physically implements the move, and what evidence licenses the resulting claim.
The unit of evaluation is not the universe. It is one claimed transfer.

The paper proposes a typed transfer record:
It keeps together:
- state transport;
- reverse-direction observable transport;
- observation post-processing or statistical simulation;
- target-equation residual;
- naturality or commuting-square defect;
- directed Blackwell–Le Cam deficiency;
- physical carrier, controller, instrument, reference frame, clock, and boundary conditions; and
- assumptions, tolerances, sources, proofs or execution artifacts, hashes, unresolved obligations, and status.
The originality claim is deliberately narrow: BSC proposes a joint contract among established mathematical primitives and supplies composition and demotion semantics for that contract. It does not claim that each primitive is new, or that no equivalent formalism exists.
BSC is not presented as:
- a fundamental ontology or unified field theory;
- proof of holography, quantum gravity, consciousness, QCD, quark charge, or hadron dynamics;
- a proof of the Riemann Hypothesis, an independent physical origin for it, or a demonstrated end-to-end quantum advantage;
- a proof of the Collatz conjecture or an official verification-frontier announcement;
- a universal law of persistence;
- a claim that every boundary determines an interior;
- a single total error score;
- a machine-checked formalization of the immutable paper or complete eight-field record; or
- a complete reference implementation.
The paper's strongest present territory is the grammar governing when boundary data, representation change, topology, learned operators, scale transfer, recurrence, or duality earns the right to support a target claim.
- A reviewer-facing preprint and editable LaTeX/BibTeX source.
- A post-v1.4.0 BSC Core v1.5 research milestone with human-readable proofs for product readiness, cyclic cap closure, operational identifiability, target-relative pair cover, and approximate oscillation; a separate pinned Lean-checked theorem slice; exact F14/F15 fixtures; proposed causal and AI-evidence profiles; and a machine-readable selected-claim package. It is not a new immutable release.
- Standalone framework modules for certified finite scale families, normalization collapse, logarithmic-rate decomposition and stability, singular-set and slice visibility, analytic zero transfer, and exact-decision bounds; and for claim-relative simulation evidence, statistical coverage, factored identity, compatibility-bounded deployment, and coupled-surrogate propagation; and for fixed compatible preparation-to-report channels, implemented-reachable-set error propagation, data processing, residual-localized energy-port gluing, denominator-typed efficiency, probabilistic encoding, and relation alignment; and an electromagnetic completion separating gauge, local Maxwell laws, constitutive response, boundary ports, calibrated reports, inverse authority, coupling normalization, and metrology.
- A post-v1.4.0 exact rational derived-holonomy certificate that returns either
a chain homotopy or a normalized left-null obstruction over
$\mathbb Q$ . - A post-v1.4.0 ASTRA source-admission crosswalk that gives dual rent a common prior and typed physical/report outcomes, proves two finite independence countermodels and a sole-sink static degeneracy, and preserves the supplied verifier and numerical contradictions as non-promotions.

Fixtures F1–F7 and F9 have exact mathematical derivations
but no separate execution receipts. F9 checks only the finite engineered
zeta–coherence identity; it does not execute the application-level analytic
transfer and is not an NMR-data replay. F10 executes only its declared exact
finite recurrence; it is not empirical or physical validation of a surrogate
model. F11 executes exact row replay and complete candidate enumeration, but
its finite-prefix conclusion remains conditional on the external NOT_REPLAYED. F13 independently checks
one scalar auxiliary-state identity and four finite energy ledgers; it is not
a continuous Maxwell execution or physical material calibration. The
immutable v1.4.0 paper includes no proof-assistant artifact; separate
post-release Lean projects check the Q26 theorem and the bounded BSC Core v1.5
theorem slice without converting the paper as a whole into a formalization.
The most useful first responses are:
- an existing formalism that already provides an equivalent joint record and semantics;
- one ill-typed map or missing hypothesis;
- a counterexample to a composition law or fixture;
- a case in which the added record changes no scientific decision; or
- a nearby valid transfer that the calculus incorrectly blocks.
If established work already supplies the same obligations and demotion semantics—or if the record never distinguishes an invalid transfer from a nearby valid one—the additional structure is unnecessary.

Version 1.1.0 adds a reusable normalized-scale profile to the
core calculus and applies it to Wei et al.'s engineered correspondence between
finite quantum observables, the
Riemann zeta function, and dynamical quantum phase transitions
(DOI 10.1038/s41467-026-74935-8).
The general layer separates a carrier
The zeta instance proves the declared finite alternating-sum identity, an
explicit local-uniform tail bound, the fixed
No raw-data replay, fitting re-execution, hardware run, or complexity benchmark has been performed in this repository. The inspected Nature Communications source was an unedited article-in-press version, so the citation state is also recorded rather than silently treated as final typeset text.
Version 1.2.0 adds a claim-relative simulation-evidence profile without changing the eight-field BSC morphism. It separates statistical simulation, computational simulation, and surrogate deployment; records intended use, typed source estimands and target BSC losses, hard gates, estimators, a joint observation law, sampling or oracle models, joint coverage, optimization gaps, proxy-transfer theorems, and factored evidence identity; and proves compatibility-bounded deployment after monotone, unit-respecting propagation:
Frozen-state estimator uncertainty already enclosed by
The finite-horizon specialization shows why standalone surrogate accuracy
does not determine coupled-host accuracy. Executable Fixture F10 uses the same
exact interface error
Version 1.3.0 adds a restricted preparation-to-report layer:
Classical interfaces use total variation, quantum interfaces use trace
distance, and POVMs form a declared quantum-to-classical boundary. For fixed
compatible ideal and implemented stages, local defects must cover the
implemented reachable set. If those defects are
This propagates state or report-law discrepancy only. It does not compose the full BSC morphism and does not resolve BSC-QOP-03.
The same module proves:
- downstream Markov, CPTP, measurement, and report channels cannot resurrect lost distinguishability; a complete postselection instrument is contractive, but normalizing on success can amplify distance;
- a uniform forward-report defect
$B$ gives two-sided containment of actual and ideal compatible parameter sets after enlarging the radius by$B$ ; - identical spectral-intensity laws can belong to orthogonal photon states, so unit marginal overlap does not certify quantum identity;
- a driven open quantum system satisfies
$\dot E=\mathrm{Tr}(\rho\dot H)+\mathrm{Tr}(H\mathcal D_t(\rho))$ under its declared split and finite-dimensional or separately justified domain assumptions; - finite additive energy-port diagrams satisfy
$R_G=\sum_vr_v+\sum_eg_e$ , so interface storage must be explicit and a globally closed residual cannot certify locally defective seams; - count yields, energy efficiencies, and conditioned efficiencies remain differently typed, and stage ratios telescope only across the identical intermediate quantity and evidence identity;
- conditionally iid scalar Bernoulli repetitions have sufficient count
$K=\sum_iY_i$ and at most$\log_2(N+1)$ bits of input information; - 256 scalar Bernoulli labels cannot be recovered with zero error for any
finite
$N$ under that model; - under
$P_{\phi(i),i}=1$ , one same-entity relation alignment requires$S=PCP^{\mathsf T}$ , not independent row and column permutations; and - generic channel form cannot derive the electromagnetic fine-structure constant. The approximate 1/137 value needs a typed QED and metrological bridge.
The first application crosswalk binds four primary publications: hybrid atom–quantum-dot two-photon interference, a driven plasmonic photonic time crystal, a Hiroshima blast-forged multicomponent alloy, and an integrated microwave probabilistic-bit processor. The commonality is evidentiary form, not a claim that these systems share one microscopic law. No hardware, spectroscopy, crystallography, classifier, or raw-data analysis was replayed by BSC.
The post-v1.4.0
ASTRA crosswalk treats the supplied
v0.3 package as a source family, not as independent validation. It freezes six
outer hashes, independently checks the package inventory, and separates
physical future
Two exact fair-bit examples show that diagnostic access can increase without
physical change and physical change can occur without diagnostic gain. The
crosswalk also derives the model-local sole-sink identity
The note allocates no new claim or fixture. It withholds the package's SPPT frequency result because the narrative and canonical JSON disagree, treats the package verifier as source asserted rather than fail closed, and leaves the Keller, prime-difference, experimental, quantum, archaeological, and origin lanes unpromoted. The strongest exact Keller candidate is deferred until after the existing electromagnetic fixture sequence.
The electromagnetic bridge instantiates the operational report envelope as
It proves gauge descent and the curvature/holonomy distinction; source compatibility and topological-flux boundaries; Poynting balance with explicit boundary, pump, material, and loss accounting; passive scattering only in a declared calibrated power metric; a magnitude-only phase/delay no-go; and field-normalization and charge-flux invariants. Maxwell boundary inversion remains theorem-, coefficient-class-, gauge-, frequency-, and data-local. Static curved-space fluxes instantiate the same energy-port theorem through metric volume and boundary forms; moving boundaries, time-dependent metrics, and non-Killing relativistic currents require their additional transport or bulk terms.
The bridge sharpens rather than reverses the 1/137 boundary. Revised-SI
definitions move uncertainty into

aperiodicity transfers to a coefficient field only under a declared faithful
materialization. A selector can instead erase the tiling or retain only its
periodic carrier: peer-reviewed Hat point diffraction is a concrete case in
which an aperiodic real-space tiling has a periodic reciprocal-space report.
