Extraction schema

The envelope the extraction model must fill. It is generated from the pinned ontology version rather than written by hand, so a schema and the claims produced under it always agree about which attributes and values existed.

SRS section 8.4, structural enforcement

Ontology version

lv-panel/1.3.0

Attributes in schema

Abstention tokens

6

A closed enumeration, not a prompt instruction.

Claims that abstained

4

Countable precisely because abstention is a value rather than free text.

Three things are enforced structurally rather than asked for in a prompt. The abstention vocabulary is a schema enum, so a model that cannot find a value has exactly one legal way to say so. The document context is tool free, so nothing can be fetched mid-extraction and presented as if it came from the document. And the extraction context is separate from the reasoning context, so a model cannot quietly reuse its own earlier output as evidence.
Abstention vocabulary
Six ways to decline, each with a defined meaning and a defined consequence.
TokenMeaningAcceptable as a valueRaises an open itemSeen in this project
UNKNOWNThe attribute was searched for and no statement about it exists in the source.noyes1
CLARIFICATION REQUIREDA statement exists but is ambiguous enough that two readings would produce different engineering.noyes1
CONFLICT DETECTEDTwo or more source statements assert incompatible values for the same attribute.noyes0
EVIDENCE NOT FOUNDA value was proposed but no source anchor could be resolved for it. Never acceptable.noyes1
MANUAL CHECK REQUIREDA value was extracted but fell outside its plausibility envelope or failed unit normalisation.noyes1
ENGINEERING APPROVAL REQUIREDThe value is a deviation from standard practice and needs a named engineering decision.noyes0
Attributes to include
The schema below is regenerated as you toggle. Nothing outside the selection may appear in the response.
Generated JSON Schema
Every attribute requires a value, the value as written, a unit, a confidence and an anchor. An extraction with no anchor cannot be represented at all.
