Do not propose interfaces before user picks architecture candidate.
If user picks candidate, enter grilling loop.
If naming new deepened module after concept missing from CONTEXT.md, update CONTEXT.md.
If user rejects candidate with load-bearing reason, offer ADR only if future reviewers need it.
Do not commit unless explicitly asked.
