/**
|
||
|
|
* Regression: FileSystemStorage must expose a public `rootDirectory` getter.
|
||
|
|
*
|
||
|
|
* Native vector plugins (e.g. @soulcraft/cortex's NativeHNSWWrapper) feature-detect
|
||
|
|
* `storage.rootDirectory` to enable their memory-mapped vector fast path. Brainy
|
||
|
|
* stores the path as the protected `rootDir`; without this public alias the native
|
||
|
|
* mmap backend stayed un-wired and the index rebuilt via slow per-entity disk reads
|
||
|
|
* on cold start (BRAINY-MMAP-VECTOR-HOOK). The getter is the load-bearing line, so
|
||
|
|
* guard it explicitly.
