Recommended action: Check the WIF authentication history page for the deny reason; mint a fresh JWT per exchange; send workspace_id for multi-workspace rules; fix host clock; use asymmetric algs with kid. Option: Read the deny reason in authentication history [evidence: official_recommended_action] Applies when: Anthropic Claude API / Workload Identity Federation token exchange Steps: 1. Open Console WIF authentication history 2. Match reason to fix (fresh assertion for jti_reused, workspace_id for workspace_id_required) 3. Sync NTP on the workload host Expected: Request accepted / failure becomes diagnosable Evidence basis (self-declared by the contributing chat client): untested.
