Quirks
- Bands never points: edges carry stake_percent_min/max, stake_percent stays None
- Listed companies are PSC-exempt (DTR5): Rio Tinto/Glencore/Anglo American absent by law
- 92% of records are natural persons - excluded by the no-persons rule
- identification.country_registered is free text (6+ spellings of UK); normalised before keying
- Controllers registered outside the UK are dropped and counted, never name-matched
First jurisdiction shipped from the ownership-percentage procurement atlas (2026-08-11).
