Terminal stability

Stable stability -- production rank 18 for the Q1 2026 cohort. 16 carriers, 25 services, 313 voyages observed in the cohort window. Terminal cadence: Hybrid.

Rank should be read as a band, not a precise placement. Bootstrap rank-stability lands between the precise and illustrative thresholds.

The six-flag structure is the published per-terminal uncertainty disclosure. Together they answer: is the sample large enough to rank, is the rank stable across bootstrap iterations, does the tier label hold under resampling, are the events concentrated in too few voyages, and is the snapshot coverage adequate for the cohort window.
