Programme LAPPIQ: AI-driven plasma photonics — preregistered refutation campaign R1–R4 (version 2.0)

Restricted-access deposit of the LAPPIQ programme of SOVEREIGNPIALPHA France Ltd (version 2.0, 19 July 2026). LAPPIQ studies plasma as a programmable photonic medium whose useful regimes are found and held by physics-constrained artificial intelligence. The deposit holds the sealed preregistration files of cycles R1 and R4, the test and verdict scripts, the primary result files, the figures, the conceptualisation and modelling dossier, and a SHA-256 manifest. The campaign used open datasets only. Intellectual-property material is excluded from the deposit. The notice and DOI are public; the files are released to evaluators and reviewers on request, and will be opened in full if an associated article is published.
