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.

// Comptime return-trace resolution (ERR E3.0 slice 3b). A `#run` block that
|
|
// raises, propagates via `try`, and catches the error, then formats the trace
|
|
// with `trace.print_current()`. At comptime a frame is a packed
|
|
// `(func_id, span.start)` (not a `*Frame`); the interpreter's `.trace_resolve`
|
|
// unpacks it and resolves `file:line:col` via the module + source map — so the
|
|
// comptime trace prints the same `func at file:line:col` form as a runtime one.
|
|
// Expected exit: 0 (the error is caught; the trace is printed during the build).
