LocalDb 0.1.1 creates the parent directory of LocalDb:Path itself, so the SiteLocalDbDirectory shim this repo carried through Phase 2 is deleted along with its call site. The gap was found here but was never ScadaBridge's alone — every LocalDb consumer had it — so the fix moved to the library. SiteLocalDbDirectoryTests is RETAINED and retargeted rather than deleted with the shim. It was already written against the site registration path, not the mechanism, so it needed only its Ensure() call removed: what a site node requires is that resolving ILocalDb not fail on a fresh machine, regardless of who provides that. Verified it still earns its place — pinned back to LocalDb 0.1.0 it fails inside SqliteLocalDb..ctor -> SqliteConnection.Open(), so it genuinely depends on the library behaviour and not on a coincidence. Also corrects the coverage-split note in StoreAndForwardStorageTests, which asserted that directory creation is "NOT LocalDb's" — true when written, wrong as of 0.1.1. Build 0 warnings; Host 330, StoreAndForward 130, LocalDb integration 20 pass. Claude-Session: https://claude.ai/code/session_01BL2Vu1ESDQ9SCN4gVKkdts
