DAS vs Passpoint

References

Every dated fact in the report carries a source. Section A lists the timeline's numbered sources; section B lists all 631 unique URLs cited in the device cohort and vendor evidence, grouped by host, with the rows that cite them. Wayback URLs carry their own capture timestamp.

Access dates: device-cohort URLs fetched 2026-09-16/17 (last committed 2026-09-17); vendor-evidence URLs fetched 2026-09-17 (last committed 2026-09-17). Wayback URLs carry their own 14-digit capture timestamp. Per-row provenance is in the CSVs' sources / wayback_url columns.
