Source-attributed profile stub — enrichment pending.
Cao Ke appears in the A–Z current-custody roster published in Rights Defense Network / 维权网 Issue 131, dated August 31, 2026. The source classifies its Issue 131 roster as political prisoners and prisoners of conscience currently in custody.
Verification status: FreeChina has not yet completed independent identity, region, case-history, custody-location, charge/sentence, or profile reconciliation for this person beyond matching the name to the source roster. This page should therefore not be read as a completed biography.
Next profile steps: reconcile name variants and identity; verify custody and case details against primary or independent sources; add dates, charges/sentence, location, organizations and related coverage; then replace this source-only stub with the canonical enriched profile.
