A fixed-d Toeplitz obstruction to degree-wise coherence for FI_d — v0.1.0 candidate

Version 0.1.0-candidate

Initial anonymous, AI-assisted, unrefereed candidate release of the fixed-d,
characteristic-zero Toeplitz obstruction for FI_d-modules presented in finite
degree.

The supplied minor-revision review was actioned in full. The release explicitly
compares Di--Li--Liang Example 3.6, corrects bibliographic and historical
attribution, disaggregates assurance, assigns publication accountability, and
adds a portable Linux replay route. The written proof, producer replay, hostile
controls, and internal editorial gate pass. Independent reproduction, formal
verification, external specialist review, journal peer review, novelty, and
priority are not claimed.
