CI Health Check Results - Sun Dec 28 08:45 PM EST 2025

Status: CI FAILED ❌

Issues Found:

1. Spell Check Failure

• File: docs/src/lectures/lecture1.md:563
• Issue: Typo "uknowns" should be "unknowns"

2. Documentation Build Failure (Julia 1.12 Compatibility)

The build fails due to upstream package compatibility issues with Julia 1.12:

• UndefVarError: 'tmp' not defined in 'OrdinaryDiffEq'
• UndefVarError: 'ForwardDiff' not defined in 'PreallocationTools'
• Failed to precompile: OrdinaryDiffEq, StochasticDiffEq, SymbolicsPreallocationToolsExt

These are upstream Julia 1.12 compatibility bugs in the SciML ecosystem packages (OrdinaryDiffEq, PreallocationTools), not issues with this repository's code.

Recommendations:

1. Fix the typo: Change "uknowns" to "unknowns" in docs/src/lectures/lecture1.md:563

2. Pin Julia version: Consider pinning the Documentation.yml workflow to Julia 1.11 until upstream packages are fixed:

   - uses: julia-actions/setup-julia@latest
     with:
       version: '1.11'
