Evidence-label schema attachment points
Evidence and PlantState, cascading
DECIDED
- Status
- DECIDED (7 Oct 2026, Vinayak)
- Options
- Attach Measured/Estimated/Assumed/Unknown (+ calibrated flag) at Evidence and PlantState and cascade; or only at ledger; or per-signal only
- Trade-offs
- Completeness vs contract churn
- Recommendation
- Attach Measured, Estimated, Assumed, Unknown (plus calibrated flag) at Evidence and PlantState, and cascade to Prescription and ValueRecord. The section 5.2 tier mapping is accepted.
- Why
- Completeness at the source is cheaper than repair downstream.
- Evidence
- 7 Oct briefing intake; sources in evidence ledger section F.
- Reversible
- Contract change only.
- Blocks
- Still open inside it: label per state element or per whole vector (recommend per element; it costs one field).
