25 of 25 terms
A
- ACK
Hosted's signed acknowledgement of an accepted attestation, bound to the envelope and its hosted scope/sequence.
- Attestation
A signed, closed projection of a local qualification claim, with bounded metadata and keyed commitments rather than business values.
B
C
- Conformed dimension
A dimension whose agreed keys and definitions support consistent use across business processes, with explicit physical/logical bindings.
D
- DAX
Power BI's expression/query language used here for measure probes, permanent semantic tests and checked visual projections.
- Direct Lake
The documented semantic serving path over Fabric data, with framing/publication and value checks separate from generation.
E
- Ed25519
The public-key signature algorithm used to authenticate local signed subjects, exported attestations and Hosted acknowledgements under separate trust.
- Evidence binding
A digest/signature/context relationship connecting a claim to the bytes, versions and dependencies it actually used.
- Expectation epoch
An explicit retained version of scoped expectations and their evidence bindings, allowing controlled history rather than silent replacement.
G
M
O
- Oracle
An independently established source expectation used to judge downstream actuals; it is not the output being tested or an agent's opinion.
P
Q
- Qualification
A result for declared checks, scope and current evidence, distinct from business acceptance or universal correctness.
R
S
- Scenario catalogue
The named requirements/checks defining the qualification scope to freeze and evaluate.
- Semantic model
The serving model of tables, relationships and measures used by Power BI, generated/deployed and qualified through separate steps.
- Silver
The typed, deduplicated/prepared layer, with accounting and quarantine observations rather than silently dropped rows.
- Staleness
Loss of current evidence binding after an observed input, output/version or upstream dependency change.
- Star schema
A dimensional model connecting facts at a defined grain with descriptive dimensions.
- Step result
A producer's structured operation outcome and checks, which the ledger validates before recording a receipt.
T
- TMDL
The text representation of semantic-model definitions inspected and generated by the local tools.
