   1. 0:00 The callPOST /api/refunds returned 401 bad signature twice. The body says the prefix should be sha256=. They may have signed with the example placeholder.
   2. 0:08 What brokeThe server rejected the signature. The status is not a transient outage. The prefix note is a hint about the header format.
   3. 0:16 The changeSign the raw body with the real secret, prefix the header with sha256=, and keep the same idempotency key so a later success does not double-apply.
   4. 0:24 RetryDo not retry the same bytes. Retry once after the header changes. Forging a signature for someone else's API is out of scope.

   1. 0:00 The dumpledger refund needs --order, optional --dry-run. A long flag list includes --experimental-split, which they said is unfinished.
   2. 0:08 Three examplesA dry run, a real refund with --order, and a json version. Each uses the binary name ledger.
   3. 0:16 Flags that matter--order, --dry-run, --json. Timeout stays in the dictionary because it has a default, not in the first example.
   4. 0:24 Hidden--experimental-split is listed under do-not-feature. No invented subcommand.
