What was already known
Evidence for a gap in finite samples or a different spin-chain Hamiltonian does not establish a length-uniform gap for the pure bilinear spin-one model.
What changed and why it matters
Establishes the stated uniform-gap formulation for the pure even-periodic spin-one chain.
The AI contribution
OpenAI attributes these manuscripts to its internal model. The entry does not infer individual human contributions beyond that publisher attribution.
Limitations
The entry covers even periodic rings and the stated pure Hamiltonian. Different boundaries, odd lengths, and perturbed models require separate statements. Preprint. This is a source-statement and significance assessment, not a proof audit. No independent checking or successful formal compilation is asserted by this entry.
Verification evidence
Evidence labels show what supports the claim. Importance rates its impact if correct.
Author claim
The publisher reports the scoped result. AIProofWatch has not independently validated its correctness.
Accessible artifact / proof
The original written argument is accessible. Availability does not establish a successful proof check or Lean verification.
Correction and publication history
Historical report added after statement, scope, and importance review. No proof audit or formal checking asserted; subscriber alerts disabled.
