meta_amp), federal role ranges are sourced
from Canada Gazette Order-in-Council appointment notices,
Parliament of Canada biographical records, and on-the-record news
of record. Per-actor ranges committed to
data/actor_tenures.json. Pairwise overlap in days
computed via standard interval intersection.
joint_score = a.meta_amp × b.meta_amp × overlap_years —
higher means more consequential cross-axis concurrent period. Where
one actor holds multiple simultaneous roles (Freeland: DPM + Finance;
Carney: BoE + UN Envoy + Brookfield), the pair's total overlap days
sum across all role-pair combinations. Full algorithm:

Single actors holding concurrent federal roles
Each card shows an actor whose federal role ranges include
simultaneous portfolios. These are cross-portfolio
accountability surfaces — a person in two federal roles at
once. Source: data/actor_tenures.json.

Structural finding · cross-axis + temporal
The Canadian federal accountability architecture reviews each single- actor role separately, and each single-axis separately. The temporal- overlap data shows the decision-making is in fact deeply concurrent and cross-portfolio.
Freeland held Deputy PM + Finance for 4.3+ years simultaneously. Carney held 4 concurrent roles for parts of 2020–2024 (BoE + UN Envoy + Brookfield + earlier BoC). Trudeau × LeBlanc overlapped for 11.4 role-pair-years covering the full range of LeBlanc's successive portfolios.
These are not separate decision chains. They are interlocking ones. No single Canadian federal oversight body has jurisdiction over interlocking concurrent cross-portfolio decision chains. The Grover + temporal-overlap combined finding names that gap, adds the time dimension that meta-Grover lacks, and makes the gap visually obvious.
