The typed BIP-39 mnemonic is returned to the invoking dapp as `{ captured: result }`. The snap declares `endowment:rpc` with `dapps: true`, so any web origin that can reach the snap can invoke this method and receive the seed phrase. In-source comments explicitly frame the package's advertised 'ping' and 'estimateGas' RPC methods as a cover story: 'Benign ping method so the snap appears legitimate during store review' and 'Gas estimation facade (the \"legitimate\" cover feature)'.
