# ITC-WP-0015 — Evidence Basis
## Goal
Give quantities a closed, ordered scale for *how they were obtained*, owned
by ITC-GOV and imported by ITC-CAP consumption, so assumed hours and
measured gigabytes cannot sit in one list as if they were the same kind of
knowledge.
## Intent
resource-control published the vocabulary and showed it grading their own
provider comparison `indicative`. They asked whether we wanted it as a
demand. We do. Ownership is GOV Evidence, not a CAP-only dialect, because
the same scale is needed on actuals and thresholds.
## Tasks
### T01 — Demand intake
```task
id: ITC-WP-0015-T01
status: done
priority: high
state_hub_task_id: "f0b4d93e-e417-44f4-9b73-b25ba23988be"
```
Steward-file `demand/EvidenceBasis.md` from the consumer's published
`docs/evidence-basis.md` and `tools/basis.py`. Do not copy the
implementation.
### T02 — Catalog and GOV section
```task
id: ITC-WP-0015-T02
status: done
priority: high
depends_on: [T01]
state_hub_task_id: "57352beb-6ac1-4757-9d93-971f5a52fd84"
```
Add `infospace/models/governance/evidence-basis.yaml` as the closed
vocabulary and §11.34a `EvidenceBasis` to the Governance Model.
### T03 — Import on CapabilityConsumption
```task
id: ITC-WP-0015-T03
status: done
priority: high
depends_on: [T02]
state_hub_task_id: "360a76f3-f0ca-4b40-b2b5-a89dbc5ac068"
```
CAP-R10: a consumption row MUST declare `basis`. Unknown carries no
quantity. ITC-CAP 0.3.0 / canon 0.4.0.
## Out of scope
- Ledger or invoiced-fact origination (fin-hub).
- Canon-wide state qualifiers (OQ-3).
- Retrofitting resource-control actuals and thresholds — that is their work
against this catalog.
