Three additive surfaces for native index providers, which hold only
`storage` and must never construct their own fact-log reader (the log's
open path is writer-side — it reconciles by truncating/rewriting):
- Fact-scan capability on the storage adapter (the getBinaryBlobPath
pattern): the host brain wires a closure over its LIVE fact log at
init; providers call storage.scanFacts()/factLogHeadGeneration()/
factSegmentPaths() and fall back to the enumeration walk on null.
Restore/reopen swaps the underlying log transparently.
- The family-stamp trio (readFamilyStamp/writeFamilyStamp/
verifyFamilyStamp + types) exported from @soulcraft/brainy/internals,
so 'one verifier' is literally one function shared with the native
side, never two synchronized copies.
- Rollup invariants widened to number|string: content fingerprints
(e.g. a per-tree SHA-256) are valid invariant values; strict equality
either way, and a type mismatch reads as incoherence, never a pass.
