parser: experimental Update 8 (saveVersion 42) compatibility - #13
Merged
Conversation
Accept headerType 13 / saveVersion 42 saves behind version gates: - header: no saveName field before headerType 14 - levels: no per-level saveVersion u32 before 1.0 (fall back to header) - actor/component headers: no flags u32 before 1.0 - persistent level: trailing collectables list still present pre-1.0 - InventoryItem property struct: pre-44 (level, path) itemState pair (new InvItemProps::LegacyRef variant) Verified on a 6GB-body U8 save (5.4M objects, full payload+index build) and regression-tested against the 1.0/1.1 suite (all 65 tests pass). Gates marked COMPAT EXPERIMENT: thresholds separate 42 from 52+ correctly but exact introduction versions for 43-51 are unverified, and editor write paths still emit 1.0-format records (do not widen the accept list or enable splice edits on old saves without auditing those). compat_probe example: header/decompress/body probe with hexdumps for diagnosing unsupported save layouts.
