Scope and method

Evidence retained in the research archive assembled through 6 October 2026. Figures, appointments and pending proceedings are dated; no later outcome is inferred. Company, committee, auditor and opposing-party accounts retain their stated limits.

Retained original reports, company statements, exchange decisions, filings and attributed reporting are reconciled by entity, period and evidentiary status. Duplicate records do not provide independent corroboration. A role in the group does not establish involvement in misconduct; anonymised operational actors remain anonymised.
