Critical — Quantum Read-Through Measurement. This article defines a transitional read-through measurement architecture in which midpoint M samples an A-to-B route without becoming the endpoint measurement authority. M is treated as a read-only witness surface: it may export a copied witness row, but it may not own the payload, repair the payload, rewrite branch identity, or decide Bob-side truth. The central contribution is the authority separation between witness sampling and endpoint certification. Multi produces raw partial reads, STLF writes the visible sign-or-zero ledger, SEB recognizes the row, and MAP enforces the permitted grade. This prevents a weak or partial read from being promoted by narrative repair. The paper also separates M as a useful stopgap bridge from Pre-Binary Sign Net as the stronger architecture. M can reduce B-side validation burden by catching route-side or A-side failures early, while Pre-Binary moves Sign Net classification to the front end before ordinary binary handling or late qudit-cell validation becomes authoritative. The included synthetic result supports the staged grammar by showing clean separation among Strong, Strong-to-Weak, Weaker, Hold, 0S continuity, and Refuse outcomes under fixed rules.

Critical — From A-Side Sign Certification To B-Side Qudit Read-Down defines a blocking boundary rule for routed qudit-facing payloads: the router may carry a sealed payload and optionally inspect a separate sign/check branch, but it may not open the payload, derive sign from x1,y1,z1, recertify the row, or convert route success into payload certification. The article’s central contribution is the Alice-router-Bob authority split: A owns launch and branch binding, the router owns transport and retained branch-event history, and B owns contained endpoint read-down. This fixes the dangerous failure mode in which routing authority drifts into payload recognition or premature measurement.
Foundational — QCore 6: Pre-Binary Sign Net Worker Beyond Quantum A-to-B, With SCADA Release — This article presents QCore 6 as the successor architecture to QCore V, preserving the pre-binary local worker while adding Sign Net custody, SCADA release, read-through M witness measurement, Sadovskii Spin First, upstream lattice carry, double-detour return, and endpoint verification into one runtime order. The central claim is that QCore remains outside the native Quantum A-to-B corridor: A-to-B, Bob verification, midpoint witness drains, binary handling, and SCADA command flow become client or bridge uses of a worker result rather than the original storytelling layer. QCore 6 classifies the richer object before ordinary binary, public-row, command-client, or endpoint authority becomes live. The worker freezes the run, declares custody, preserves typed-zero pressure, separates recognition from enforcement through SEB and MAP, releases only bounded survivors, and verifies exported endpoints through sealed capsules. The article also supplies a JSON-style replay template and falsifiable tests for SCADA custody, stored-anchor separation, 2.75 continuity, Sadovskii Spin First, lattice forecast, read-only M witness use, double-detour return, and full QCore 6 replay.
Critical -- From Photon Cavity To Check-Branch Custody: Passive QEC, Metadata Repair, And Early Read-Only Certification This article uses passive quantum error correction of photon loss at breakeven as a source foothold for a broader certification problem. The source demonstrates a superconducting cavity system in which photon loss changes parity and engineered dissipation supports passive replacement, reaching a reported break-even point for the encoded qubit lifetime. The article then asks whether the middle of the correction process should be treated only as a hardware-repair problem or also as a custody and metadata-certification problem. The central contribution is the separation of live quantum payload from encoded metadata. The photon/cavity state remains the live carrier of the quantum data, while a check branch carries only parity, syndrome, address, time window, branch identity, support markers, custody hash, and repair rule. This metadata branch cannot recreate destroyed quantum data, but it may make partial degradation actionable while the encoded carrier remains recoverable. The article develops this into a cavity-side read-only architecture. Instead of waiting for Bob-side endpoint validation, the first witness surface is moved to the cavity, where the encoded object is formed and where degradation begins. Multi-zone witness reads, STLF token writing, SEB recognition, MAP enforcement, typed-zero returns, and QCore-style worker custody are used to classify repair, hold, release, downgrade, refusal, 0S continuity, or 0T blockage before endpoint validation becomes the main burden. The result is not a replacement for physical quantum error correction. It is a proposed software-governed metadata-custody overlay that may reduce unnecessary middle hardware burden, improve early refusal, preserve audit visibility, and move the architecture toward local cavity-side worker certification before photon-loss timeout.
Critical – Endpoint Authority Before Path Detail: Non-Hermitian Amplification Under Strong-to-Weak Custody. This article develops a Sign Net reading of endpoint-only non-Hermitian amplification. The source result is first treated in its own terms: in adiabatic non-Hermitian systems, geometric amplification can depend only on start and end points when the imaginary Berry curvature is zero, with reciprocity and Petermann-factor ratios providing important endpoint structure. The article then separates outside-Sign-Net Strong parameter authority from inside-Sign-Net Strong-to-Weak custody. Petermann_start, Petermann_end, and Petermann_ratio are introduced as source-native endpoint witness tokens, while P-Lane, Positioning Pad, Centered-X, and Four-Solves-Three place and audit the endpoint row. The article’s main contribution is the forward route: endpoint geometry may supply Strong authority outside Sign Net, but Sign Net intake translates that authority into a Strong-to-Weak candidate because stored-anchor custody, typed-zero accounting, SoZ pressure, Detour return, and Flip 2.5 gate-in/gate-out routing still have to be enforced. The result is a contract-grade method for using endpoint authority without turning path independence into an unguarded shortcut.
Foundational — Gate-On First: A Bidirectional Sign-Net Protocol for Controlled-Z Gate Certification with Typed-Zero, Mapped Support Matching, and D4 Custody. This article should be read as a reusable external-certification architecture for connecting device-independent quantum-gate evidence to Sign-Net decision custody. The protocol records the gate-on block first as a frozen, ungraded candidate while preserving the source-compatible certification order in which the identity-setting correlations establish the upstream reference structure before the unitary-setting evidence receives authority. Full device-independent and almost device-independent operation remain separate report classes, and the Sign-Net engine receives only committed external settings, outcomes, source and repeater records, isolation evidence, confidence intervals, and frozen reference definitions rather than hidden information from inside the tested gate. The article replaces literal Local-inside-Universal language with mapped support matching across distinct observations. A Local record containing four mapped items and a gate-on record containing ten items can establish four shared matches and six active-only items without treating the two physical conditions as simultaneously nested. A two-knob measurement then reads bottom-up Local somethingness represented in the gate-on candidate and top-down gate-on nothingness relative to the Local demand. These quantities use separate denominators and remain distinct from physical emptiness, unresolved missingness, (0T), and inherited (0S) custody. Cross-Chain Closure compares the opposed Local/identity records at the fixed (S=0) address and separately compares the returned gate-on block with the frozen first observation. D4 retains candidate evaluation, typed-zero review, mapped matching, final grading, and all onward promotion authority. D5 provides bounded recovery and Strong-to-Weak witness return, while D6 receives only D4-authored full-sign or Strong-to-Weak (0S) promotion. A fourteen-scenario Monte Carlo grammar test produces fifteen thousand baseline D6 promotions with zero false-physical certifications, zero unsafe promotions, and zero missed-certifiable outcomes inside the declared synthetic suite. A separate Weaker-to-D6 countertest produces five thousand false and unsafe promotions, directly fixing the promotion boundary while leaving Bell self-testing and physical device-independent implementation to upstream experimental work.
Critical — This article, Optical Switch Protocol Verifies Entangled Quantum States in Real-Time without Destroying Them, turns a real-time sampled-certification source into a much stronger operation-first program by fixing the exact blocking failure the source leaves open: sample economy alone does not establish measurement-compatible use. The paper raises the bar by separating gentle contact from terminal readout, adding containment at R≈1, requiring declared placement, enforcing recognition-versus-enforcement separation through SEB/MAP/SEBMAP, preserving indexed zeros through STLF, and making final acceptance answer to typed-zero and no-backflow discipline rather than to a favorable statistical story. That is why this lands as Critical rather than merely Significant: it does not just add another structure around the source result, it fixes the missing operating layer that stands between “some copies survive because they were untouched” and “a branch can be weakly contacted, held, released, and certified without narrative repair.”
