  name: "Tag Contextualisation"
  status: "draft"
  purpose: "Map raw industrial tags to assets, variables, units, process states and semantic roles."
  algorithm_type: "composite"
  inputs:
    - tag list
    - asset hierarchy
    - historian metadata
    - engineering documents
  outputs:
    - canonical tag mapping
    - validation warnings
  implementation:
    type: "external_or_runtime"
    note: "Implementation is runtime-specific; this card describes the governed algorithm object."
