This file is a pointer for Codex sessions. The canonical project orientation, non-negotiable rules, architecture locks, working conventions, and milestone cadence live in CLAUDE.md.
Read CLAUDE.md first. Then docs/design/ROADMAP.md for the milestone plan.
The two files are kept in sync by treating CLAUDE.md as the single source of truth: changes land there, and this file remains a one-line pointer to avoid drift.
