ADR-009: Manual metadata minimisation
- Status: Accepted
- Date: 2026-07-17
Context
Open question #9. Heavy forms kill contribution.
Decision
- Required for upload: journey/section confirmation (after alignment), consent, essential device/app provenance (automatic).
- Optional post-recording: carriage region (front/mid/rear), phone placement, crowding, sitting/standing.
- Campaign-only: richer fields for research drives.
Consequences
Autos where reliable; never block upload on optional carriage trivia.
