ab78883db2 Pre-rewrite reference checkpoint — final state of the salvage/prototype codebase (C0/C0b complete) 
The rewrite (D-049) starts from a clean slate; this commit is the reference
implementation of the graduated design.

200adcaf5a feat: config-gated flat-scalar sea level (D-033, terrain-water task 04) 
SeaLevelModel: "flat" (one scalar, SeaLevelValue) or "field" (the
legacy latitude Lerp 0.26..0.15). Only GetSeaLevel's body changes —
all nine call sites (crater carve target, both flood fills, biome
split, beach band, Capitol window, town filters, A* zero-point)
inherit the model automatically; no consumer re-tuning. Default:
flat 0.15, pinned in ServerConfig.json.

8532d88771 feat: blueprint v2 reader dispatch + validation + params cross-check (terrain-water task 02) 
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.
