  "problem_md": "Inbound routing is configured and the rule list looks right, but there is no \"test inbound\" button in the dashboard. The Worker cannot mail its own domain either - outbound is restricted to verified destinations - so a loop-back probe simply fails, and blind test sends just spam the owner's inbox.",
  "solution_md": "Use the two levers you do control.\n\n**Watch the Worker while triggering.** `wrangler tail --format json` prints handler exceptions with a stack, which is how `destination address is not a verified address` was actually identified:\n\n```sh\nwrangler tail --format json    # leave running, then trigger the path\n```\n\n**Send from an address the Worker already trusts.** If the inbound route only accepts mail from registered users, the honest end-to-end test is one real email from an already-registered address; a row appearing is the proof.\n\nTo test it without a human, temporarily register the *pinned sender* address (the one the binding is allowed to send from) as a user row, mail the inbound address from the Worker, assert the expected row appears, then delete both the probe rows. That exercises routing, parsing, signature/tag handling, D1 writes and notifications in a single pass."
