## Layer 1: Bayesian Analysis
### P0 (Elo Prior)
- Canada Elo: 1556
- Bosnia Elo: 1380
- P0: Canada 60.7% / Draw 18.2% / Bosnia 21.1%
### Likelihood Updates
- [home] Canada 4-4-2 lineup confirmed from expert; key starters: Tajon Buchanan, Ismael Kone, Stephen Eustáquio (±4%) — lineup
- [away] Bosnia 4-4-2 lineup confirmed from expert; key starters: Ivan Sunjic, Benjamin Tahirovic, Amar Memic (±4%) — lineup
### P1 (Final Bayesian)
- Canada: 60.8% | Draw: 18.1% | Bosnia: 21.1%
## Layer 2: Monte Carlo (FM-Style)
- Simulations: 1,000
- Avg Goals: Canada 1.19 / Bosnia 1.13 / Total 2.32
- Avg Shots: Canada 17.5 / Bosnia 17.0
- Conversion: Canada 6.8% / Bosnia 6.7%
- Avg Cards: 3.6
### Top Scorelines
- Canada 1-1 Bosnia: 15.1%
- Canada 1-0 Bosnia: 12.3%
- Canada 0-1 Bosnia: 10.0%
- Canada 2-1 Bosnia: 9.1%
- Canada 0-0 Bosnia: 8.7%
## Layer 3: Synthesis
**Confidence: LOW** (max divergence: 23.4%)
- Method weights: Bayesian 50% / Monte Carlo 50%
- Rationale: Methods diverge materially; averaged estimate is shown, but confidence is low and diagnostics should drive interpretation.
### Divergence Analysis
- Bayesian is higher on home win by 23.4pp. Likely evidence-layer effect (2 evidence items) rather than player-chain simulation.
- Monte Carlo is higher on draw by 11.2pp. Likely generative simulation effect from squad duels, tempo, or factors (0 factor effects).
- Monte Carlo is higher on away win by 12.2pp. Likely generative simulation effect from squad duels, tempo, or factors (0 factor effects).
### Consensus Estimate
- Canada: 49.1% | Draw: 23.7% | Bosnia: 27.2%
