lesson_candidatesList

Candidate lessons awaiting human promotion; empty array is valid.

lesson_candidates[].causeText

Attributed cause, one of the five code-defined values in, :86-131

Example: unrecovered_variation

lesson_candidates[].statementText

The candidate lesson, stated as cause + drift + period + project.

Example: Unrecovered variation work reduced margin by 1.8 points o…

lesson_candidates[].provenance.monthText

Claim-cycle month the drift is measured in.

Example: 2026-07

lesson_candidates[].provenance.drift_ptsNumberUnit: margin points

Signed margin movement that cycle.

Example: -1.8

lesson_candidates[].provenance.evidenceText

The observed signal behind the cause (e.g. a diary-flag count)

Example: 6 diary variation signals in 2026-07 vs 3 approved variat…

lesson_candidates[].promotion_gateText

Explicit "candidate only, human sign-off required" marker.

Example: candidate_only_human_signoff_required

observability_gaps_rankedList

Data gaps that made a cycle unattributable, ranked; empty array valid.

observability_gaps_ranked[].gapText

The named missing data (e.g. no diaries for a month)

Example: no site diaries recorded for June

observability_gaps_ranked[].margin_points_obscuredNumberUnit: margin points

Total absolute drift the gap obscures.

Example: 2.1

observability_gaps_ranked[].monthsList

The months in which that gap occurred.

promotion_gateText

Record-level candidate-only marker.

Example: candidate_only_human_signoff_required

Optional

Present when the source system records them.

lesson_candidates[].provenance.drift_dollarsNumberUnit: AUD

Points scaled by contract value; null when no contract value.

financial_periodText

Use this contract

The contract is a standard JSON Schema (draft 2020-12) document, so any JSON Schema validator can check a record against it. Keywords starting with x-demiton- add Demiton's own meaning, such as units and requiredness, and validators ignore them.
