Rodin 6af8a6ee10 refactor(findings): split ALL-FINDINGS.md into per-experiment files
Break the monolithic 3249-line findings file into 29 individual files,
one per experiment. Each file is named YYYY-MM-DD-NN-slug.md for easy
chronological sorting and discovery.

No content changes — purely structural reorganization.

# Finding 5: Sonnet is fast and catches structural issues; GPT-5 is slow and catches semantic issues
**Date:** 2026-04-26
**Task:** Dual review across PRs #372, #375, #378, #380, #382
**How we used them:** Same pr-review skill, same context (diff + files +
issue + AC), same sub-agent pattern. Only variable: model. Both got rich
context. Both ran the full 7-phase review skill.
- Sonnet consistently finishes first, catches formatting, broken links,
structural problems (missing sections, dangling refs)
- GPT-5 takes longer, catches meaning-level problems (verdict mismatches,
classification inconsistencies, logical gaps)
- **Takeaway:** With identical rich context and identical instructions, the
models naturally gravitate to different things. Sonnet is the structural
reviewer; GPT-5 is the semantic reviewer. Both roles matter. Question:
would Sonnet catch semantic issues if given a narrower "check for logical
consistency" framing instead of broad review?
