Ships the smolmachines backend's prepare side: subpackage layout,
`_BACKENDS` registration under "smolmachines", preflight check
for `smolvm` + `gvproxy` on PATH, and the two config-file
renderers (Smolfile TOML + gvproxy YAML). Launch raises
NotImplementedError until chunk 2.
New module layout (mirrors backend/docker/):
claude_bottle/backend/smolmachines/
__init__.py re-exports SmolmachinesBottleBackend
backend.py SmolmachinesBottleBackend façade
bottle.py SmolmachinesBottle stub (NotImpl until ch2)
bottle_plan.py SmolmachinesBottlePlan + .print()
bottle_cleanup_plan.py SmolmachinesBottleCleanupPlan stub
prepare.py resolve_plan: writes both config files
smolfile.py TOML renderer (stdlib, no tomli_w dep)
gvproxy_config.py YAML renderer (same shape as pipelock_yaml)
util.py preflight + per-slug subnet + loopback port
The renderers are pure functions. `resolve_plan` runs the
preflight, allocates one host-side loopback port per active
sidecar (pipelock always; git-gate / supervise conditional),
derives a per-slug gvproxy subnet (hash-mod-254, skipping the
docker-default 17), and writes:
- <stage>/gvproxy.yaml: subnet + DNS rule resolving only
`proxy.internal` + port_forwards (one per active sidecar).
- <stage>/smolfile.toml: guest command/env + virtio-net device
backed by gvproxy's unixgram socket. No TSI flags — see
PRD 0023 "Why gvproxy, not TSI".
The agent's HTTPS_PROXY etc. point at `proxy.internal:<gateway-
port>` so the guest dials through gvproxy. gvproxy resolves only
`proxy.internal` → the gateway IP, and forwards exactly the
listed ports to the host-side sidecar bundle (PRD 0024); every
other destination — host LAN, host loopback, public internet
directly — is unreachable by construction.
29 new unit tests covering renderer correctness, subnet
derivation stability + collision-avoidance, loopback port
allocation, and preflight error paths. Full unit suite: 532
passing.
