# 01-RESEARCH Investigations that have not yet hardened into design. ## Structure Each effort lives in `NNN-descriptive-name/` and **must** contain `status.md` with: - a short summary of the effort - who initiated it - the areas it touches - current status: `ONGOING`, `GRADUATED`, or `ABANDONED` An effort graduates by producing an ADR and a `02-DESIGN` entry. It is abandoned in place — never deleted. What was rejected, and why, is the more expensive half to rediscover.
