List bulk AP migrations Detected bulk migrations between Access Points, largest first. A cohort is a gap-≤3-day island of (from_provider, to_provider) mover days that clears three thresholds: at least 25 participants, at least 40 % of them on the busiest day (which rejects a steady drip), and at most 20 active days for the pair over the trailing 40 days (which rejects a recurring partnership). Every day is the PROBE-OBSERVATION day — the day the change scan saw the SMP record change, not the day the migration was executed — so a cohort is always a `[first_day, last_day]` range and `peak_day` is the busiest observation day. Render the range, never a single date. `top_country` is derived from the ICD prefix of the participant identifiers, not from business-card country fields. `merge_suspect` marks a cohort large enough (or whose source provider no longer resolves in the directory) to be a provider merge or a renamed provider rather than that many independent customer decisions — the canonical case is Sovos → Sage, 10,574 participants. Such rows are data events, not customer decisions; verify one before quoting it. The flag is a CURRENT judgment, re-evaluated on every recompute, not frozen at detection. `from`/`to` are OVERLAP bounds (a cohort counts when its range intersects the window), defaulting to the trailing 90 days the detector re-clusters. Mover history begins 2026-07-24, so no cohort predates it. `id` is a request-lifetime handle for the participant drill-down — never persist one.
