🔬 New AI Craft

1. Human vs. AI: line-level provenance for text under agentic editing
A tool that derives authorship (AI-written vs human-written) for every line from version history alone, not from in-file markup — closing the attribution gap in AI-assisted development. Pairs well with agentic coding workflows: after an agent rewrites large chunks, you can pinpoint exactly which lines need human review instead of re-reading everything.

2. Quoted $1M for AI code review. Built it for free
The author walks through how they were quoted $1M for an AI diff-review tool, then built a working one themselves — covering cost breakdown, diff context organization, and prompt design. A grounded reality check for anyone adding AI code review to their pipeline.
