Where Cortex already solved it, **inherit, don't re-derive**. See [docs/wiki/cortex-inheritance.md](docs/wiki/cortex-inheritance.md) for the requirement-by-requirement map.
-**Cortex research cutoff:** when ingesting Cortex for context, **ignore commits before `af3a76f5` (2026-01-26)** — the pre-container Piyush-era EC2/SSH/Vercel architecture that was replaced wholesale and teaches patterns that conflict with current picortex ADRs. Use `git -C ~/code/cortex log af3a76f5..HEAD` as the reachable set.
+**Cortex research cutoff (revised 2026-04-23):** Don't *inherit* patterns from pre-`af3a76f5` Cortex (the Piyush-era EC2/SSH/Vercel design, 2026-01-20 → 2026-01-23), but *do* study it deliberately — several of its patterns (bot/workspace physical split, `claude -c -p` per turn) are exactly what the texting-first picortex wants. See `docs/wiki/piyush-era-design.md` and `docs/plans/2026-04-23-prototype-options.md` (Option 2).
