ROADMAP.md was named as a destination in two places but never created,
indexed, or read back. Add the convention to how-i-work.md, note it after
the README decision tree and in the loads-when table, give it a row in the
portability layer table, make the retrofit prompt create it, and have
handoff seed it and pull from it when Current state's next steps run thin.
- Handbook: evaluator/security-auditor are opus/xhigh, not opus/high (matches wrappers).
- portability.md / retrofit-playbook.md: how-i-work.md is ~50 lines, not 'under 50' (it is 52).
- retrofit-playbook.md daily rhythm: close out with /handoff, not the old manual paste, matching README and the handbook.
Align portability.md with the handoff refactor — every command and
subagent is now a thin wrapper whose substance lives in guides/, with
no self-contained inline exceptions.
Document the portability protocol (vendor-neutral knowledge, vendor-named
symlinks) and a Claude subagents reference handbook, and link the
portability protocol from the retrofit playbook.
