Reader sniffs the first byte (0x49 raw-ISLA v2 vs 0x07 v1 string prefix) and routes to the v2 tagged-section parser or the intact v1 path (v1 loads log a deprecation warning — fallback stays live). v2 validation: magic/version gate (loud reject), MapSize sanity bound [256, 32768] before allocation, every section length checked against remaining file, section-consumed-exactly check, params-first and no-duplicate-section rules, biome and town-tier ordinal range checks. Unknown tags skip by length — the forward-compat property D-030 buys. ServerChunkManager cross-checks embedded params against config (seed + MapSize) and logs a prominent desync warning — canon H7's silent failure becomes loud. ServerConfig.json pins the reference world: WorldSeed 1409879727, 8K. Round-trip oracle GREEN: reference v1 (537,054,156 B) -> v2 (335,727,522 B, -192 MB) -> parse -> semantic equality holds (heights bitwise, biomes, 94 towns, 4/1/37/39 road paths point-for-point). v1 parse 1.9s, v2 write 1.4s, v2 parse 1.6s.
