B-07 privacy-layer boundary audit Rows: 18 (3 tools x 6 observable fields) Method: source-bound boundary classification; counts are not a privacy score or ranking. As-of: 2026-08-13 Monero: exposed=3, partial=1, protected=2, unknown=0 SimpleX: exposed=1, partial=4, protected=1, unknown=0 Cryptomator: exposed=4, partial=0, protected=1, unknown=1 Interpretation boundary: a protected field is protected only from the named observer and only within the documented scope. Unknown means the cited source does not establish the property; it is not evidence of exposure or protection.
