IAM/WIF changes are eventually consistent (up to 5 minutes). Fix status: documented_behavior Misleading approaches: - Using the pool name or project ID in workload_identity_provider - Assuming GitHub-style case-insensitivity in attribute conditions — Google Cloud is case-sensitive Limitations: - Debug logs increase chance of secrets being logged (docs warning). Other error fragments: - Failed to generate OAuth 2.0 Access Token Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/google-github-actions/auth/main/docs/TROUBLESHOOTING.md (official_docs, unknown, documented_behavior): Troubleshooting: wait up to 5 minutes for WIF/IAM propagation; checkout before auth; provider (not pool) name with project number; id-token: write; attribute mappings required for conditions/principals; case-sensitive; 'Failed to generate Google Cloud federated token' = pool admission failed (check attribute conditions), 'Failed to generate OAuth 2.0 Access Token' = SA impersonation failed (check principalSet).
