- G-059: capability-probed WSL constraint for driving unix-side tests from Windows (multishell sh-payload execution, runtime.bash behaviour). Native-filesystem execution is a design constraint: per-test artifacts staged into a WSL-native tempdir with one-way copy-in/out, no repo checkout inside WSL for these cases, future full-suite mode via a separate native clone - the Windows checkout is never operated on via /mnt (DrvFs slowness + cross-boundary stat differences force git index re-hashing and fossil phantom changes; two VCS clients must not share a working tree). Acceptance includes verifying the Windows checkout git/fossil state is untouched by a WSL-gated run.
- G-060: QEMU guests as strictly external tooling behind a hypervisor-agnostic guest-driving contract (provision/stage/run/collect, push-based - same pattern as G-059; guests never share a working tree with the host). GPL-safe posture recorded: external-process invocation only, no QEMU binaries or derived code in punkshell or punkbin, guest OS images not redistributed - fetched/built per machine. First target FreeBSD x86_64; config home deferred to the buildsuites toml direction.
