unityz 0.1.5

Changed

• Object writer/verify: rewrites now preserve an original object's
  alignment-padding bytes and nonzero true bool bytes. Unity leaves
  struct memory in padding and stores a bool as any nonzero byte, so
  zero-padded rewrites differed from the original in those meaningless
  bytes and verify reported correct decodes as failures. verify
  passes the original buffer through (writeObjectPreserving); edits
  still write normalized zero pads. Class-114 verify round trips after
  the fix: The Forest 324→20, Green Hell 2617→1698, Stranded Deep
  540→386, Raft sharedassets0 354→74, Raft level0 25→21.
• Verify: NaN payloads no longer count as differences. An f32 NaN
  widened to the value tree's f64 and cast back cannot reproduce the
  original payload, and Unity's data holds quiet NaNs whose exact bits
  no rewrite preserves (Raft's TMPro font gradients). After this,
  verify's bytes-differ count is zero across every test game; the
  remaining failures are all read failures from older class layouts.
• managed --trees matches more of Unity's MonoBehaviour serialization:
  [HideInInspector] publics serialize, [NonSerialized] (via the
  fdNotSerialized field flag) does not, delegates never do, bools and
  nested-record byte/char/short fields occupy their own 4-byte cells
  while top-level byte/char/short runs pack, strings inside arrays pad
  per element, native engine structs (LayerMask, Hash128) use their
  fixed layouts, and generic/cross-assembly base chains resolve
  (TypeSpec extends, one name index over all assemblies).
  Every class-114 object that reads now round-trips byte-exactly
  (bytes-differ zero across all five test games). The remaining
  failures are read failures from data authored by older class layouts
  (documented in features.md).
• Object reader/writer: strings inside arrays are each 4-aligned, not
  packed into one run. A string[] whose payload is not a multiple of 4
  misread every following element (an out-of-bounds read on Green Hell's
  ConstructionSlot.m_MatchingItems). Round trips: Green Hell class-114
  3546→2594, Raft level0 35→23, The Forest 527→478.
• Library: the typed views that build variable-length lists (GameObject,
  Font, ComputeShader, the audio mixer and animator families) take the
  caller's allocator and return Allocator.Error!T; they allocated through
  a hard-coded page allocator that was never freed and swallowed
  out-of-memory. Every typed view now carries a doc comment, the library
  root's status paragraph reflects the current module set, and
  asset_extensions includes .resource.
