- Add the abi.localize_runtime profile field: the archive build combines the
program object with exactly the runtime/vendor members it reaches and
demotes every external definition except the profile-declared symbols to a
local symbol (darwin: one ld -r pass with -exported_symbols_list; linux:
ld -r then objcopy --keep-global-symbols)
- N archives built under pairwise-distinct prefixes now link into one process
with no symbol collisions and no shared mutable runtime state: each
instance owns a private copy of the allocator, collector, result arena, and
panic sink, so sinks register per instance and a trap poisons only the
instance it fired in
- Document the embedder contract beside the profile spec: one thread per
instance (an instance is never entered from two threads), and values cross
instances only through the embedder's own byte/record marshalling
- Refuse cross-target localized builds with SC3002 (the step runs the host
toolchain's ld/objcopy over host-format objects); absent or false keeps the
classic single-archive artifact byte-for-byte
- Add the two-instance acceptance probe (two archives, two embedder threads,
independent collects, a trap delivered to its own sink exactly once while
the other instance keeps answering) plus symbol-exactness, profile-shape,
and target-posture suites, and schedule the artifact contracts on the gate
host
Bump all published packages to 0.0.26, publish the release notes for the new target and runtime surfaces, and regenerate the compiler surface manifest.
