allocators/fs/process/socket/log/trace/test move under modules/std/ (allocators.sx becomes std/mem.sx; the Allocator protocol moves into the std.sx prelude, impls stay in mem.sx). New std/xml.sx holds xml_escape as xml.escape. std.sx gains the carried namespace tail — flat-importing std.sx now also provides mem./xml./log. — with the remaining modules (fs/process/socket/json/cli/hash/test) deferred from the tail until the global last-wins maps are fully own-wins (pulling them into every closure collides bare names corpus-wide; they stay direct imports: modules/std/fs.sx etc.). log.sx's internal emit renamed log_emit (it clobbered consumer fns named emit program-wide). bundle.sx uses xml.escape via the carried alias. Consumer import paths swept mechanically; .ir snapshots recaptured for the larger std closure. m3te + game build unchanged.

// A protocol method declared `-> *void` (literal void-pointer return,
|
|
// NOT `Self`) returns the underlying impl's pointer to the caller
|
|
// unchanged. The dispatch path must NOT auto-load from the result —
|
|
// `*void` outside a `Self`-disguise is a real pointer whose pointee
|
|
// size is unknown.
|
|
//
|
|
// Regression: target_type leaks from the surrounding scope (e.g. the
|
|
// enclosing function's return type). The dispatcher used to auto-load
|
|
// `sizeof(target_type)` bytes from every `*void` return, mistaking
|
|
// real pointers for Self-encoded boxes. Result was that
|
|
// `alloc.alloc(64)` through an Allocator protocol value returned the
|
|
// first 4 bytes of malloc'd memory interpreted as `s32` (= 0 → null).
