docs/logs/2025-10-27-phase2h-progress.md You will be orchestrating subagents to finish Phase 2 of this implementation plan, using the prompts in phase2-subagent-prompts.md. We are translating liblinear to Julia.

Review the docs/logs/phase2-todos.md TODOs. Some of these are actually already done but not checked off; do a first review to identify and check these off. This list should cover every task you need to do. Many are done already.

Dispatch at most 1-4 subagents at a time in parallel, if you know they won't conflict. If you're concerned, do 1 at a time. Start with 1 at first to avoid issues. Then as you progress, you can do a some in parallel.

	Read https://docs.julialang.org/en/v1/manual/style-guide/, https://docs.julialang.org/en/v1/manual/performance-tips/, https://docs.sciml.ai/SciMLStyle/stable/. Then assess the Julia code base (src) against these. Write three docs, one for julia style guide adherence, perf tips adherence, and sciml style guide adherence with lists of specific deviations. Score the impact of the deviation in terms of the effect on the codebase, 0 = no impact, 5 = highly consequential. Sort the docs from most-severe to least. Check them into docs/logs/$date-$name.md and push. Don't make any changes to the code or other files.

	I'll help you assess the LibLinearJL.jl codebase against the Julia style guides. Let me break this down into tasks:
	Update Todos
	Fetching Julia style guide documentation
	Fetch Julia performance tips documentation
	Fetch SciML style guide documentation
	Read and analyze src/ directory code
	Write Julia style guide adherence report
	Write performance tips adherence report

	You will be orchestrating subagents to run Phase 2 of this implementation plan, using the prompts in phase2-subagent-prompts.md. We are translating liblinear to Julia.

	Make a large todo list in docs/logs/phase2-todos.md with checkboxes. This should cover every task you need to do. There will likely be 30+.
