Japan and Iran are intensifying diplomatic engagement following the resolution of detention issues involving Japanese nationals.

Calibration

MEDIUM tier, this pattern is present in calibration data but with limited resolutions. Treat the confidence as a directional estimate, not a precise probability.

Entities

• Tehran (place) gravity 0.0533 · momentum +0.088 · Q3616
• Tokyo (place) gravity 0.0015 · momentum -0.080 · Q1490

Signals

• factor 12.4
• window_days 30
• edge_weight_prior 0.5
• edge_weight_recent 6.2
• event_count_recent 10

Confidence (52%) is computed numerically from these signals. The sentence prose was written by an LLM given only the structured signals as input, the LLM never sees or chooses the confidence number.

What would change our mind

Edge weight between Tehran and Tokyo returns to its 30-day baseline, or two clean weeks pass with no fresh co-mention from a tier-1 source.

Inversion conditions are a property of the pattern detector, not the LLM. Watch for this signal move and the claim should weaken or be superseded.
