## TL;DR

GitHub Actions token and secret evidence tells agents whether a workflow can read code, write statuses, call deployment APIs, or safely access repository secrets.

## Core Explanation

CI failures often look like code failures when they are actually permission failures. A job may lack the `contents`, `checks`, `pull-requests`, `deployments`, or `id-token` permission it needs, or a secret may be unavailable because the workflow came from a fork, Dependabot event, reusable workflow boundary, or protected environment.

Agents should inspect the triggering event, fork status, repository and organization defaults, workflow-level `permissions`, job-level `permissions`, environment name, and which secret names are referenced before editing YAML or rerunning a deployment. When a workflow can fall back between secret names, the evidence trail should record which secret was present and which API call succeeded.
