Read the native container beyond its preview: the chain of allocation tables (#FAT, #FT2, #FT3, #FT4) with newest-revision selection, CRC-checked extraction of stored, zlib and zstd entries with their byte predictors, and the self-describing tagged object stream in doc.dat as a generic tree of shared, inline and positional objects. Every declared size is checked against per-entry and per-import budgets before allocation; the zstd window is capped at 64 MiB; table chains are cycle-checked; arrays are checked against the remaining bytes; object nesting stops at 384 levels. The header now accepts container versions 8 to 12 and the flag values 4 and 8 that real Affinity 3 files carry (the previous check rejected the public CC0 Affinity 3 documents); the thumbnail record is the same in all those versions. Checked against 176 public documents saved by Affinity 1.x to 3.x: every doc.dat decompresses with a matching CRC and parses with no bytes left over. A test-only `synth` feature builds synthetic containers for unit tests and fuzz seeds; it is not an Affinity exporter.
