v3.3.0

[3.3.0] — 2026-07-21

Changed

• Vendored core bumped to v3.3.0 (see Source/ThirdParty/SuperFAISS/CHANGELOG.md and
  VENDORED_VERSION.txt for the full delta) — adds PeekScratchArchive/
  ScratchArchiveInfo (header-peek geometry + trailer-byte-offset read for a serialized
  scratch archive, not yet consumed by this plugin); fixes ScratchBank::Load's retention
  validation, a segmented-scan/whole-row-scan kernel-selection disagreement at several
  paddedDims, an int64 arena-size overflow in ScratchBank::Create/Grow when
  geometry ceilings were not enforced first, and a Cosine channel bank with zero rows
  being unrepresentable; and lets MeanNNCrossDeviceChannel/MaxNNCrossDeviceChannel
  return OutOfMemory.
• ComputePrincipalComponents's scratch parameter is now double* (was float*)
  in the vendored core. This plugin's one call site
  (SSuperFAISSBankInspector::ComputeProjection, the PCA scatter-plot projection behind
  the Bank Inspector's Structure/Novelty views) updated its scratch buffer from
  TArray<float> to TArray<double> to match; no other behavior change.

Fixed

• Channel-table Offset + Length arithmetic widened to int64 before every bounds
  check, in USuperFAISSVectorBank::InitFromSource,
  USuperFAISSVectorBank::RebuildChannelTable, USuperFAISSScratchBank::InitWithChannels,
  and USuperFAISSScratchBank::Relabel — all four BlueprintCallable entry points. The
  caller-supplied int32 sum could overflow before comparison, defeating the channel's own
  bounds and ascending-order checks. A malformed table was never actually accepted or
  stored — the vendored core's ValidateBank already rejects it downstream with
  BadFormat — but the plugin's own channel-rules guard was inert for the overflowing
  input, so the caller received a generic downstream failure instead of the specific
  diagnosis, and the signed overflow was undefined behavior regardless of reachability.
  Matches the core library's own fix for the same defect class in ScratchBank::Create
  and Grow.
