diagnostics

On policy_invalid only. Each problem with its line, code and hint.

Array<object>

One finding about a policy file, with its position and the next step. Codes are stable and listed in docs/POLICY_ERRORS.md. In the policy_invalid error envelope each diagnostic also carries object: policy_diagnostic. The full PolicyDiagnostic schema is in openapi.yaml.

object
action

One agent action. Its sections mirror the deed’s. status is the one field an agent needs; state is the exact lifecycle state (docs/GATE.md). The Gate’s own responses (POST /v1/actions and its result report) add execution.result and witness.reasons; lists leave both out. The full Action schema is in openapi.yaml.

object
checks

On undo_unavailable only. Every check of the undo, each with its fix. Additive (S23).

Array<object>

One of the twelve safety checks (S23 §3.3). Available means no check failed. The full UndoCheck schema is in openapi.yaml.
