"scope": "Actual BlockStateProvider DIRECT_CODEC/TYPED_CODEC and simple, weighted, random_block, rotated, copy_properties, randomized_int three noise-based providers and rule_based over the pinned state registry. All states and block defaults, full-state versus typed exclusive decoding, ordered holder sets/tags, duplicates, empty optional results versus world-state fallback, zero/overflow weights, query failures, every state across six fixed rotations, nested random rotations, property copying for every target state against representatives of every compatible property value, integer-property ranges/missing properties, composed transforms and subsequent random consumption. Native property equality families are checked for ambiguity; Rust validates Cartesian state tables and uses compact property strides. Both legacy/xoroshiro streams execute directly and through WorldgenRandom. Noise comparisons include every bundled provider definition, independent legacy seeding, float/double scaling, dual-noise variety selection, threshold draw order and coordinate/codec boundaries. Rule-based comparisons cover true/not/all_of/any_of/inside_world_bounds/height_range/volume_match/matching_block_tag/matching_blocks/matching_fluids/matching_biomes/unobstructed/solid/replaceable/has_sturdy_face/would_survive predicates, ordered optional results, fallbacks, nested rules and world-query failures. Every pinned block-state fluid identity, amount, falling/source flag and own-height bits are derived from descriptors and compared. Fluid-holder sets and all bundled fluid tags are tested against every state. Biome-holder membership and all bundled biome tags are compared across every pinned biome identity, including empty sets, missing names, ordered world queries and short-circuit composition. Unobstructed predicates compare null excluded entities, exact translated unit-shape bounds, ignored-but-validated offsets, true/false world results and failures. Named holder versus direct/typed decoding, nested named providers, missing names, inline ambiguity, ordered resource registration and all bundled named definitions are compared. Solidity and replacement predicates cover every block state, offset wrapping/validation, empty-child fallthrough, composed predicates and query failures using privately imported definition flags and Rust-calculated collision solidity.

One-to-one vanilla gameplay parity is the acceptance criterion. It has **not**

It can read and export region files and access saved and resident block sections.
Scheduled block/fluid queues can now collect and dispatch callbacks with

Double-precision geometry and voxel-grid queries are implemented, with a registry
adapter for vanilla's no-context cached collision branch.
Base noise samplers, octave stacks, normal-noise definitions and bulk density
sampling are implemented. Compiled density samplers now evaluate constants, gradients,
shifted noise, all eleven unary operators, rounding and selected arithmetic operations. An initial density graph compiler
integrates range analysis, specialization, uniform-axis slicing, shared caches,
nested splines and seeded noise;
complete graph coverage, serialized graphs and generated terrain remain absent.
The Rust workspace implements core arithmetic/random streams, world data and
resident sections, scheduled tick ordering, geometry, contained fluid states,
noise/density evaluation, biome and terrain generation kernels, material rules,
and parts of feature placement and decoration. All pinned block-survival
families now have native differential coverage. Full simulation callbacks,
complete chunk generation, entity behavior, networking, rendering and playable
