Pull request overview
Adds a new blog post describing how an AI-assisted workflow (Coq + HOL Light proofs plus CBMC _Float16 symbolic checks) was used to fix a long-standing floating-point fmod/remainder soundness issue in CBMC, and how proof/verification interplay helped catch incorrect assumptions.
Changes:
- Introduces a long-form post narrating the bug, why it’s hard in CBMC’s circuit encoding, and the final integer-significand + FMA approach.
- Documents how SMT solvers and
_Float16symbolic checks found issues that a “passing” proof initially missed. - Summarizes the CI strategy for keeping proofs, implementation, and checks in sync.
