Compares ordered chunk/state/suffocation/shape calls, missing-chunk retries, cached chunk reuse, face/edge/corner filtering, canonical full-block versus equal noncanonical shape behavior, exact emitted shape data, early consumer termination and injected provider failures. Finite bounded scans include thin/zero-size boxes, chunk crossings and wrapped integer positions. Registry-specific metadata/shape dispatch, live chunk loading and entity movement are separate integration work; unsupported cursor volumes and caller budgets use typed Rust errors."

[regression report](../benchmarks/rust-canonical-collision-2026-10-06/contextual-regression.json).

Five import tests cover legacy data, equal-but-distinct grids, canonical restoration
|
||||
and malformed identity metadata. Workspace Clippy passes without warnings.
|
||||
|
||||
|
||||
`BlockCollisionScan` now implements lazy cursor selection around entity bounds.
|
||||
It retains the native epsilon-expanded cursor, X/Y/Z visit order, skipped corners,
|
||||
large-shape face filtering, moving-piston edge filtering and suffocation-before-
|
||||
shape query order. Only successful chunk lookups are reused; absent chunks are
|
||||
queried again. Shape selection uses the global collision world, while suffocation
|
||||
uses the selected chunk. Canonical full blocks use native AABB intersection;
|
||||
other shapes use moved voxel intersection. Returned positions are independent
|
||||
values. Providers supply current block metadata and contextual shape selection.
|
||||
|
||||
`python3 tools/test_block_collision_scan_parity.py` compares **4,176 fixtures**
|
||||
and **517,820 matching lines per JAR** in the
|
||||
[collision-scan report](../benchmarks/rust-block-collision-scan-2026-10-06/scoped-parity.json).
|
||||
The native iterator runs over controlled metadata, shapes and chunk availability;
|
||||
traces cover early termination, missing chunks, query failures, thin/zero-width
|
||||
bounds, integer-coordinate wrapping and equal shapes with different canonical
|
||||
identities. Two Rust API tests cover finite/bounded input requirements, cursor
|
||||
visit budgets and termination after errors. Unsupported cursor volumes return
|
||||
errors; Java's overflowing iteration counts are outside this bounded API.
|
||||
Registry/world integration and live movement still need implementation.
