Carry ResourceAlias visibility on copy encoders containing buffer copies,
inline updates or fills, using the contribution from PR #200. Operations
through sparse virtual mappings also need ordering against surrounding
operations: disjoint guest addresses can name the same physical bytes,
so guest-range dependency detection alone misses their hazards.
Add a regression using distinct no-copy Metal buffers and real sparse
mappings. The original host failed 37 of 101 checks on an M4 Pro and
PR #200 alone left 24 failures; the complete fix passes all 101 checks
with both direct and deferred encoding under Metal validation. Ordinary
independent buffer operations retain range-based batching.
Validation: t_nvn passes 154 checks; the Mac host builds; all 133 iOS
source compile checks and the documentation checks pass. Monster Hunter
Rise gameplay, iPhone execution and sparse-barrier performance were not
retested.

Apple GPUs truncate Depth16Unorm load-clears while rounding fragment depth,
so clearing to 0.5 stores 32767 instead of the fragment's 32768 and fails
an EQUAL comparison. Apply the format-specific correction to both
attachment and whole-texture clears, preserving other depth formats.
Exercise both production command paths against independent GPU fragment
writes for 1,042 float depths, including half-bin boundaries and adjacent
floats. Removing either correction produces 518 mismatches on M4 Pro;
with both corrections enabled, neither path differs. Record the mechanism
and the pending TOTK highlight and iPhone validation in the documentation.
Validated on M4 Pro with Metal validation: t_depth16_clear, t_clear_ds
(43 checks), t_clear_tex (49 checks), and the documentation tests pass.
