Verified-source ledger and evidence gates (25 October 2026)

This is a current verification supplement, not a claim that the historical archived research report’s old conversational citation tokens resolve. Research lead: Biswajit Jana. Record exact dates, paper versions and DOI when implementing a model.

Subject Verified primary source Established result What this repo has not verified
Deep-space laser communication NASA/JPL DSOC mission, NASA 18 Sep 2025 267 Mb/s at ~31 million km near the experiment’s shorter ranges; technology demonstration concluded 2025 No direct Exo/Proxima operational extrapolation; no match to our illustrative telescope model
Peer-reviewed DSOC link physics IEEE 10.1109/JSTQE.2025.3625968 Real measured optical terminal and link performance and ranging regimes No independent published-data reprocessing yet
CCSDS physical layer CCSDS 141.0-B-2 March 2026 non-coherent optical physical-layer standard No standards-conformant packet generator/modem yet
CCSDS optical coding CCSDS 142.0-B-2 March 2026 non-coherent optical coding/synchronization No coded link or compliance test; old 142.0-B-1 is superseded
Photon information efficiency Dacha et al., arXiv:2501.13356 14.5 bits/incident photon and 17.8 bits/detected photon reported for one experimental system Not a universal bound; not reproduced in our simple hard-decision model
Interplanetary transport RFC 5325 LTP motivation Long-RTT, outage-tolerant transport cannot assume terrestrial rapid handshakes No implemented LTP/DTN transport layer
Gaia astrometry Gaia DR3 archive data model Epoch, reference-frame and correlated astrometric columns have defined semantics No frozen Proxima source vector, validation checksum or propagated covariance
Warp metric taxonomy Bobrick–Martire, arXiv:2102.06824 Some positive-energy subluminal constructions; speculative superluminal classifications No validated physical FTL device
Energy-condition critique Santiago, Schuster, Visser, arXiv:2105.03079 General warp energy-condition restrictions; convenient observer tests are insufficient No validated source material, energy condition over all observers, or chronology solution
Microscopic ‘Hyperwave’ prior art Pieri, arXiv:2311.12069 Published speculative warp-based communications, so ‘tiny warp for signals’ is not a new idea on its own No independent replication of Einstein tensor/source and no physical realization
No-signalling quantum control Quantum reduced-state identities and classical channel requirement Local operations on Alice’s half cannot select Bob’s unconditioned marginal alone No spacelike field hardware experiment conducted

Minimum evidence levels

  1. Verified published measurement: Cite instrument, physical range, wavelength, transmitted/received power, BER/BLER, data-rate definition and DOI.
  2. Reproduced numeric science: Code revision, source input, seed, numerical precision, analytic limiting cases, independent implementations, uncertainty/calibration.
  3. Physically plausible but unvalidated design: Clearly specified power, peak duty, pointing and receiver environment; published engineering bounds; no unsupported extrapolation.
  4. Speculative actual-metric route: Full Einstein source analysis, energy conditions and stability plus causal set J_plus(A) in actual geometry. Reduced travel time versus flat reference is not identical to causal violation.
  5. Extraordinary measured signalling: Blinded fresh-message intervention, reliable pre-causal-boundary decoding, anticontamination and independent physical replication. No experiment presently satisfies level 5.

Novelty opportunities (research questions, not discoveries)

Engineering — strongest immediate route: Which photon-efficient waveform/FEC/background-gating choices maximize confirmed delivered new science bits per Joule subject to laser peak-power and pointing constraints, and can time-stamped predictive residual tiles outperform conventional compression at the same end-to-end reliability? Compare to measured DSOC engineering, not fictional scenarios.

Causal statistics: How often do mutual-information estimators, shared model priors, improper time slicing and clock offsets create apparent prelight correlations? Quantify sensitivity, preregistered false positives and independent reproduction under deliberately contaminated controls.

Theoretical GR: Can a previously published proposed micro-warp communication metric be reconstructed in an independent symbolic/numerical solver, with complete source constraints and chronology analysis? A negative physical realizability result is publishable if validation is rigorous.

Correction policy

If a source is inaccessible, unverified, updated or contradictory, document that status rather than inventing an equation, a value or an experimental result. Revisit this ledger before each release and prior to any public publication.
