Why Codex wrecks your git history

• Hook is exactly the preferred shape and earns its premise immediately — no warmup tax.
• '280 vs 40 lines' are presented as facts: these MUST come from real runs on the linked repo. If fabricated or cherry-picked, technical_validity collapses to 4 and verdict flips to revise.
• 'AST-aware' is dropped as a settled fact with zero mechanism shown — either demonstrate it with a scene or cut the term; right now it reads like marketing copy inside a technical argument.
• The bisectability argument is the sharpest, most non-obvious insight in the piece; the current script buries it in beat 4 — it should be the structural spine, not a supporting point.
• Codex CLI whole-file-rewrite tendency is directionally accurate based on observed o3 behavior, but the comparison is sensitive to prompt wording; one sentence of hedging ('with default prompts') would neutralize the most credible objection without softening the argument.
• Git log scene with real-looking hashes is the strongest visual in the storyboard — good call making that a full scene rather than a callout.
• 'Surgical' appears twice across narration and storyboard; it is slightly worn but does not cross into slop.
• Repo CTA buys back credibility on the specificity claim — if the repo is real and runnable, platform_safety and technical_validity both firm up to 8.
