Rejected or Downgraded Sources

• Reuters and AP background stories were helpful context but were not used as core evidence because the report is anchored in primary or official sources.
• External commentary that tried to declare the 2026 USMCA outcome in advance was downgraded because the review is still in progress.

Evidence Notes

• The article treats Mexico as a North American production corridor rather than a generic emerging market.
• The article separates the homicide trend from the missing-persons problem because those two indicators do not move in lockstep.
• The article keeps judicial reform and USMCA review as open institutional questions, not settled conclusions.

Open Questions

• How far the judicial reform will alter court independence in practice.
• Whether the USMCA review will produce durable changes in rules of origin, labor enforcement, energy policy, or customs enforcement.
• Whether improvements in homicide averages will reduce disappearances, extortion, and journalist violence at the state level.
• Whether power, transmission, and permitting constraints will limit nearshoring despite strong external demand.
