"scope": "Actual ChunkAccess.fillBiomesFromNoise, LevelChunkSection.fillBiomesFromNoise and chunk/section biome reads using synthetic registered holder identities. Ordered resolver queries, section contents and clamped/wrapped chunk lookups are compared after repeated fills and failures at section boundaries. Covers full supported aligned vertical bounds, generation bounds cutting through sections, negative/extreme chunk coordinates and 1..512 possible biome identities. Completed earlier sections survive failure while the failing section retains its previous values. Additional BelowZeroRetrogen.getBiomeResolver cases compare all three retained cave keys, a lookalike foreign namespace, ordinary keyed holders and a direct holder without a key. All four combinations of upgrade activation at resolver construction and after construction test the captured wrapping decision. Candidate invocation order, injected candidate failures, old-column reads with quart Y fixed to zero and X/Z wrapping, repeated fills, and overlap of generation bounds with the old column section are exercised. Synthetic generation bounds deliberately override the fixed native retrogen height to expose section commit/read ordering. Direct holder values and all keyed holders are identity-only placeholders; biome properties are not evaluated. This compares stored biome values and resolver behavior, not native in-memory palette layout, wire encoding, biome-source generation integration, nonempty blending or complete generated worlds."

"scope": "Actual ChunkGenerator.doCreateBiomes through NoiseBasedChunkGenerator with empty Blender, in ordinary and below-zero upgrade modes. Both bundled Overworld/Nether multi-noise preset tables are independently exported from authenticated JARs; Rust imports quantized tables and compiles climate routers itself. All seven bundled routers, both random modes, multiple seeds and distant positive/negative chunks are tested. Complete section biome values and subsequent BiomeManager block lookups are compared, including repeated generation with fresh density contexts and persistent previous-leaf search state, and generation bounds excluding top/bottom sections. Holders are identity placeholders; no biome properties are evaluated. Fixed, checkerboard and End source fixtures also run actual chunk generation through every bundled router, including real seeded End erosion, the central-island shortcut, distant coordinates and wrapped checkerboard shifts. Retrogen cases initialize patterned old biome columns, install actual below-zero metadata with a full target on an empty persisted-stage ProtoChunk, and use its native generation height. Four below-zero noise settings, all source kinds, fixed candidates for each of the three retained cave biomes, both random modes, signed/distant seeds and repeated fills are compared. Above-zero stored biomes remain checked alongside regenerated sections and block-level biome zoom. Rust composes seeded candidate resolvers with the independently tested retention fill. Preset builders, complete biome-source codecs, nonempty blending, complete terrain-stage scheduling and complete generated worlds remain pending."

### Below-zero biome retention
|
||||
|
||||
`RetrogenBiomeResolver` captures whether an upgrade is active when the resolver
|
||||
is created. Later metadata changes do not add or remove its retention policy.
|
||||
It always samples the candidate first. Keyed `lush_caves`, `dripstone_caves` and
|
||||
`deep_dark` in the `minecraft` namespace are retained; other candidates read the
|
||||
old biome at the same quart X/Z and quart Y = 0. Unkeyed holders do not qualify.
|
||||
|
||||
`BiomeChunk::fill_with_retrogen` reads committed old sections while staging the
|
||||
current section separately. A failure preserves that section's old values;
|
||||
later sections can observe earlier completed writes. This matters when supplied
|
||||
generation bounds overlap the section selected by the clamped old-column read.
|
||||

||||
The [retention/fill report](../benchmarks/rust-retrogen-biome-fill-2026-10-06/scoped-parity.json)
|
||||
records **593,152 matching lines per reference JAR**, with 40 fixtures, 740 fills

||||

Synthetic generation bounds deliberately override the fixed native retrogen height to expose section commit/read ordering.
