Build a tidy tibble of metric metadata from reference JSON

Flattens the nested reference JSON (systems → factors → sub_factors → indicators → metrics) into one row per metric. This tibble is the central input for the flagging pipeline — downstream stages join against it rather than re-traversing the JSON.

Usage

build_metric_meta_df(json)

Arguments

json

Parsed reference JSON list.

Value

A tibble with one row per metric and columns: metric_id, system_id, factor_id, subfactor_id, subfactor_path, factor_path, preference, an_threshold, direction, factor_threshold, evidence_threshold.
