    "CRITICAL — the IaC pipeline identity is usually the most privileged automated principal in the estate; assess it as a production identity rather than as build infrastructure, and treat a runner holding standing administrative credentials as a critical finding regardless of how well the repository is reviewed.",

A plan stage running with mutating credentials means any code able to run during plan — a provider, a module, an external data source, a fork's pull request — executes with the ability to change infrastructure without any apply ever being approved.",
    "CRITICAL — if apply does not consume the reviewed saved plan, the review is advisory. An apply that re-plans applies whatever the configuration and remote state produce at that moment, which may differ from what the approver read; state which mode the pipeline uses and never let the stronger interpretation stand by default.",
    "HIGH — a saved plan file records sensitive values in cleartext, so it is a secret in transit between stages: flag any pipeline that stores it in a general-purpose artifact store, exposes it to fork-triggered jobs, retains it beyond the apply, or prints it into a log.",
    "HIGH — static long-lived cloud credentials in CI are a standing finding. Short-lived workload-identity credentials issued per run are the supported alternative, and they also make every action attributable to a run rather than to a shared key that appears identically in every audit trail.",
    "HIGH — approval is only a control if the approver can see the plan, cannot be the author, and cannot be bypassed silently. Report each of those three properties separately, because a pipeline usually satisfies one or two and the missing one is what gets used.",
    "HIGH — enumerate every trigger that can reach the apply path, not just the intended one. Fork pull requests, comment commands, tag pushes, scheduled runs, and manual dispatch each need their own answer, and the dangerous one is almost always a path nobody listed when the pipeline was designed.",
    "HIGH — runner-side configuration lives outside the repository and can redirect provider installation or inject credentials without any diff; require the runner image definition and CLI configuration before certifying an execution path, and label the assessment incomplete rather than passing when they are unavailable.",
    "MEDIUM — a self-hosted runner shared between infrastructure and application pipelines extends the estate's most privileged identity to everything else that runs on that host; treat shared runners as a trust-boundary finding rather than a capacity decision.",
    "MEDIUM — name where operations actually execute. Remote execution moves the work into the platform's environment and the local runner's credentials stop being the operative ones; an assessment that does not establish the execution location is assessing the wrong trust boundary.",
    "MEDIUM — an emergency bypass path is part of the control design, not an exception to it: if one exists, report who may use it, whether its use is recorded, and whether anyone reviews that record, since an unaudited bypass is the effective permission model.",
    "MEDIUM — unattended apply is legitimate for changes whose blast radius is bounded, but the boundary must be enforced mechanically rather than by convention; report a policy of 'we only auto-apply safe changes' with no enforcing check as an unenforced boundary.",
