Recommended action: Inspect the actual sub claim for the job (environment vs ref, immutable form) and update the trust policy with StringEquals/StringLike to that exact form; ensure permissions: id-token: write and aud sts.amazonaws.com.
Option: Match the trust policy to the real sub claim [evidence: official_recommended_action]
Applies when: OIDC role assumption failures
Steps:
1. add permissions: id-token: write
2. determine claim form (ref/environment/immutable)
3. update Condition StringEquals/StringLike token.actions.githubusercontent.com:sub accordingly; aud = sts.amazonaws.com
Expected: Role assumed
