type: decisions_registry
entry_prefix: BDR
schema:
  id: BDR-XXX
  date: YYYY-MM-DD
  title: string (<= 80 chars)
  decision: string (what was chosen)
  why: string (motivation, context)
  alternatives: list of strings (what was rejected + why)
  status: [proposed | accepted | deprecated | superseded]
  supersedes: BDR-XXX (optional)
rules:
  - Append-only. Never rewrite past entries - add a new one with status superseded if needed.
  - One entry per non-trivial choice. Trivial = reversible in under 10 min with no cross-file impact.
  - Capture why more carefully than what - the what rots, the why lasts.
