"""Daemon buy-symbol resolver regression (dcy-011/REQ-007, REL-004 smoke finding).

Exercises the REAL Daemon._resolve_symbol against a REAL SnapshotStore — the gap
that let `asset.symbol` (wrong; SnapshotStore.get returns a SnapshotAsset whose
symbol is on `.item.symbol`) ship: unit tests injected a stub resolver, so the
daemon wiring was never run until the REL-004 live smoke timed out every buy.
