(C) regToValue (comptime_vm.zig) gained no array arm, so a #run returning
an aggregate containing an array bailed 'reg->value: aggregate shape not
bridged yet'. Add an .array arm: read N elements at stride
typeSizeBytes(elem) from the array address, bridge each recursively via
regToValue -> an .aggregate Value (serializeAggregateValue already emits
arrays). Composes with struct fields, nested arrays, array-of-structs,
and the ?Arr optional payload; unbridgeable elements bail loudly.
(E) A global failing #run proceeded into LLVM emission and panicked
'unresolved type reached LLVM emission' when the unresolved const was
used. Add 'if (self.comptime_failed) return;' in emit() after Pass 0 so
it aborts cleanly (exit 1, the comptime diagnostic) across run/ir/build.
Regression: examples/comptime/0644-comptime-run-array-aggregate.sx.
Verified by 3 adversarial reviews, suite 793/0. Filed separate bugs found
during review: 0181 (optional-chain ?. to array field + index panics),
0182 (body-local #run unbridged silently miscompiles).
Add an .optional arm to regToValue in comptime_vm.zig: read the
has_value flag at offset sizeof(child), bridge the payload recursively
into a { payload, i1=true } aggregate when set, yield .null_val (zero
{T,i1}) when clear or the bare null sentinel. Matching serialize arm in
serializeAggregateValue (emit_llvm.zig). Pointer/?Closure/?Protocol-child
optionals and array-payload aggregates bail loudly, not silently.
Regression: examples/comptime/0643-comptime-run-optional-aggregate.sx
(present ?T, present ?i64, null ?i64). Verified by 3 adversarial reviews.
Move examples/*.sx and their expected/ snapshots into per-category
subfolders (examples/<category>/...). Folder = leading filename token,
with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus
runner and LSP sweep now discover each category's expected/ dir, while
issues/ stays flat. Example 1058's repo-root-relative companion import
is made file-relative. Path strings embedded in 164 snapshots were
regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.
