Event scores 18.26 on A-scale (below 25 threshold) and 31.36 on B-scale (above 25). A-score: Election interference concerns (2.5×0.22) regarding foreign observation of separatist movements, rule of law (3.0×0.18) for potential sovereignty violations, separation of powers (2.0×0.16) for international boundary concerns, capture (2.5×0.14) for foreign influence dynamics, corruption (1.5×0.10) for potential coordination. Norm erosion mechanism applies 0.7 modifier as no formal institutional change occurred. International scope adds 1.3 multiplier but narrow population limits impact. Severity: durability 1.1 (diplomatic tensions persist), precedent 1.2 (sets concerning pattern). B-score: High Layer 1 (outrage: Trump allies watching Canadian separatists, novelty: unusual foreign involvement, media-friendly: geopolitical drama). Strong Layer 2 (timing: coincides with US-Canada tensions, pattern match: fits interference narrative, mismatch: sovereignty concerns vs actual impact). Intentionality 9/15 (suspicious timing, narrative alignment, amplification) yields 0.55 weight. D-score: -13.10 clearly indicates List B classification.
