First, fund-safe step of "migrate a legacy wallet to a seed wallet": mint a brand-new BIP39 mnemonic wallet in an ISOLATED throwaway datadir so the user can later sweep funds into it. No funds move and the real wallet.dat / main daemon are never touched — the isolated node runs concurrently on its own port. - EmbeddedDaemon: one-shot isolated-datadir override (setNextStartOverride) consumed on the next start(); a skip-default-port-check for an isolated instance beside the main daemon; and a tcpPortInUse() probe. The datadir's basename must be the assetchain name (DRAGONX) and the daemon reads <datadir>/DRAGONX.conf itself, so no -conf is passed (both learned from live testing against the hd-transparent-keys daemon). - SeedWalletCreator (src/daemon): picks a free port, writes a throwaway conf, starts an isolated dragonxd with -usemnemonic=1 -connect=0, waits for RPC, calls z_exportmnemonic + z_getnewaddress (the sweep target), stops it, and keeps/scrubs the temp datadir. Off-thread; the seed is wiped after use. - App: beginCreateSeedWallet (background) -> pumpSeedMigration (main-thread handoff) -> renderSeedMigrationDialog (Intro -> Working -> Show seed -> Error), reusing the seed_display grid + clipboard auto-clear. - Settings: "Migrate to seed…" button (full-node gated) + persisted pending migration state (dest address + temp datadir) for Phase 2 to adopt. Validated end-to-end against the hd-transparent-keys daemon: the isolated node comes up in ~4s and returns a 24-word mnemonic + a shielded z-address. Requires that daemon (the bundled Jun-28 build lacks z_exportmnemonic). The migration modal uses English literals for now (as renderBackupDialog does); the whole flow gets translated once Phase 2 finalizes it. Phase 2 (sweep + adopt) is next.
