// the panel IS the human approval.

// The panel sends `autoApprove: true`. Here we drive the same HTTP endpoint the
// panel uses and prove both halves of the contract against ONE tool that gates
// itself: the `policies.create` core tool carries a `requiresApproval`
// annotation, so with no matching policy in play the annotation is the only
// thing that can pause the call.
//
//   - without `autoApprove`: the call pauses (the panel would have dead-ended
//     on "This tool requires approval"), and the policy is not written.
//   - with `autoApprove`: the call runs to completion and the policy is written.
//
// The created policy is a `block` rule on a unique, non-matching pattern, so a
// leak cannot gate another scenario's tools; it is removed in an `ensuring`
// finalizer regardless.

// `autoApprove: true` on `POST /executions` still comes back `"paused"` instead

// (packages/core/api/src/executions/api.ts), the handler
// (packages/core/api/src/handlers/executions.ts), `startPausableExecution`'s
// `autoApprove` short-circuit into `runInlineExecution` with `acceptAllHandler`,
// `makeFullInvoker` -> `makeExecutorToolInvoker`, and the static-tool dispatch
// + `enforceApproval`/`buildElicit` in packages/core/sdk/src/executor.ts — every
// layer threads the per-call elicitation handler correctly and matches the
// already-working `policies.list` gate exercised by
// scenarios/browser-approval.test.ts. No defect found by static reading; this
// needs a live-debugged trace of the sandboxed `codeExecutor.execute` run to
// find where the accept-all handler stops taking effect. The feature and this
// test shipped together in the same commit (a150db97, "Run panel: auto-approve
// operator-invoked tools (#1183)") and this scenario has never gone green on
// main since — a real product bug, not a stale assertion; suspect: the
// autoApprove short-circuit in packages/core/execution/src/engine.ts's
// `startPausableExecution` (or its sandbox integration), needs live debugging.
