style(smolmachines): provision_git stub uses pass not del
Addresses PR #69 review comment: `del plan, target` was just a silence-the-unused-arg gesture but reads oddly for a stub. `pass` is the standard "this is a stub" sentinel. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

feat(smolmachines): provision_prompt + provision_skills (PRD 0023 chunk 4a)
First slice of chunk 4: implement the two provisioning methods
that don't depend on agent-image tooling beyond `cp` and
`mkdir`. provision_ca / provision_git / provision_supervise
land once the agent-image gap is solved (chunk 4b+) — they need
update-ca-certificates, git, and the claude binary respectively,
none of which the chunk-2d alpine placeholder provides.
What this PR ships:
- `claude_bottle/backend/smolmachines/provision/` subpackage
with `prompt.py` + `skills.py`. Each routes through
`smolvm.machine_cp` / `machine_exec`. provision_prompt mirrors
the docker contract (file always copied; return value drives
--append-system-prompt-file iff the agent has a non-empty
prompt). provision_skills mkdir + cp per skill, matching
the docker backend's loop.
- prepare.py now writes the prompt file under
agent_state_dir(slug) with the agent's `prompt` body, mode
0o600. The in-guest path is `/root/.claude-bottle-prompt.txt`
(alpine has no `node` user; will become `/home/node/...` once
the real claude-bottle image lands).
- launch.py calls `provision(plan, machine_name)` after
machine_start. The returned prompt path threads to
SmolmachinesBottle so exec_claude can add
--append-system-prompt-file when the agent has a prompt.
- backend.py: provision_prompt / provision_skills now real;
provision_git is a deliberate stub (waiting on the git-gate
inner Plan + git in the agent image). provision_supervise
stays the chunk-2d stub.
Tests:
- 7 new unit cases (test_smolmachines_provision.py): argv
shape (mocked smolvm.machine_cp / .machine_exec),
prompt return-value contract, no-op-with-no-skills,
CLAUDE_BOTTLE_GUEST_SKILLS_DIR override, fail-on-missing-skill.
- 1 new integration case in test_smolmachines_launch.py:
end-to-end verification that the prompt file lands in the
alpine guest at /root/.claude-bottle-prompt.txt with the
expected content (via `bottle.exec("cat ...")`). The smoke +
the two TSI probes stay green.
552 unit + 4 integration (Darwin+smolvm+docker gated) passing.
What's left in chunk 4:
- 4b: thread the inner Plans (PipelockProxyPlan / EgressPlan /
GitGatePlan / SupervisePlan) through prepare + launch so the
bundle daemons actually run (currently daemons_csv="").
- 4c: the agent-image-conversion gap — get claude-code + git +
curl + ca-certificates into the guest image (build a
.smolmachine via `pack create --from-vm` after manual setup,
or push the docker image to a registry smolvm can pull).
- 4d: provision_ca + provision_git + provision_supervise once
4b + 4c land.

feat(sidecars): egress binds 127.0.0.1 when EGRESS_LISTEN_HOST is set (PRD 0023 chunk 3)
Egress's bind address is now env-driven via EGRESS_LISTEN_HOST. Unset → mitmdump's default (all interfaces) — the docker backend's behavior, unchanged. Set to `127.0.0.1` → mitmdump binds localhost only. The smolmachines launch sets EGRESS_LISTEN_HOST=127.0.0.1 in the bundle's env unconditionally. TSI's allowlist is `<bundle-ip>/32` (IP-only, not port-granular), which would otherwise let the agent dial `<bundle-ip>:9099` and bypass pipelock's DLP by talking to egress directly. Binding egress to localhost inside the bundle closes that gap at the socket level — the agent still reaches the IP (TSI permits it) but egress refuses the connect because it's not listening on the docker bridge interface. The docker backend doesn't set the env var because its agent dials egress directly via the docker network alias — egress MUST be reachable from outside the bundle there. The asymmetry is documented in the entrypoint script's comment. Changes: - egress_entrypoint.sh: read EGRESS_LISTEN_HOST, conditionally pass `--listen-host <host>` to mitmdump. - smolmachines/launch.py: BundleLaunchSpec.environment now includes `EGRESS_LISTEN_HOST=127.0.0.1`. - New unit tests (5): the entrypoint script's argv shape under various env combinations, verified via a fake mitmdump shim that prints its argv. 545 unit + 3 integration tests passing. The egress-port-bypass probe from chunk 2d still passes (chunk 2d ran with daemons_csv="" so no egress was up; chunk 3 makes the probe preserve its property once egress IS up in chunk 4).

feat(smolmachines): end-to-end launch + Bottle.exec + smoke + probes (PRD 0023 chunk 2d)
End-to-end launch flow for the smolmachines backend. Brings up
the per-bottle docker bridge + sidecar bundle, creates and
starts the smolvm guest pointed at the bundle's pinned IP via
TSI's `--allow-cidr <bundle-ip>/32`, yields a SmolmachinesBottle
handle that routes exec/cp through `smolvm machine exec / cp`,
tears everything down on context exit.
launch.py:
- ExitStack-managed: create_bundle_network → start_bundle →
machine_create → machine_start (each registered for reverse
teardown).
- daemons_csv="" for chunk 2d — bundle init logs "no daemons
selected" and idles. Real daemon bringup with inner-Plan-driven
env + volumes lands in chunk 4.
bottle.py:
- SmolmachinesBottle.exec → smolvm.machine_exec (captured).
- SmolmachinesBottle.exec_claude → direct subprocess.run with
inherited TTY for interactive sessions.
- SmolmachinesBottle.cp_in → smolvm.machine_cp.
Architecture pivots forced by smolvm 0.8.0's CLI shape:
1. `--from <smolmachine>` and `--smolfile <toml>` are MUTUALLY
EXCLUSIVE in smolvm 0.8.0. We need --from to avoid the
registry-pull race that bit us on machine_start (libkrun
agent's network attempt got refused by macOS with
"connect: permission denied" on IPv6). So Smolfile is dropped
entirely; per-bottle env + allow_cidrs flow as CLI flags
(`--allow-cidr CIDR`, `-e K=V`) directly to machine_create.
2. `smolvm pack create --image` doesn't pull from the local
docker daemon — only OCI registries via crane. The real
claude-bottle:latest image lives in the local docker daemon
and isn't reachable that way. Chunk 2d ships with an alpine
placeholder; the agent-image-conversion gap belongs to
chunk 4 (push the image to a registry, or smolvm grows a
docker-daemon transport).
Other changes:
- machine_create grew `image=` / `from_path=` / `allow_cidrs=`
/ `env=` kwargs; smolfile= dropped.
- bottle_plan: smolfile_path → agent_from_path + guest_env.
- prepare: pack_create against `alpine:latest`, cached under
~/.cache/claude-bottle/smolmachines/ keyed by image ref.
- Deleted smolfile.py + test_smolfile.py (dead code now).
Tests:
- Unit: 540 passing (smolvm wrapper grew 4 new flag forms; one
test renamed to reflect --from + --allow-cidr + -e combo).
- Integration: 3 new cases in tests/integration/
test_smolmachines_launch.py, gated on Darwin + smolvm on PATH
+ docker + not GITEA_ACTIONS:
* smoke: bottle.exec("echo hello-from-vm") round-trips with
the correct stdout + returncode.
* localhost-reach probe: agent dials 127.0.0.1:9 → connect
refused (TSI's <bundle-ip>/32 allowlist doesn't include
loopback). The regression test for the gap the PRD design
pivot was about.
* egress-port-bypass probe: agent dials <bundle-ip>:9099
(egress's port) → connect refused. Chunk 2d has no
daemons running so nothing's listening anyway; chunk 3
will preserve this property once egress is up but bound
to 127.0.0.1 inside the bundle.
End-to-end smoke + both probes green locally on macOS with
smolvm 0.8.0.

feat(smolmachines): bundle bringup on per-bottle docker bridge (PRD 0023 chunk 2c)
claude_bottle/backend/smolmachines/sidecar_bundle.py — primitives for the per-bottle bridge + bundle container with pinned IP: - bundle_network_name(slug) / bundle_container_name(slug) - create_bundle_network(name, subnet, gateway) - remove_bundle_network(name) - start_bundle(BundleLaunchSpec, env=) - stop_bundle(slug) `BundleLaunchSpec` carries the launch-time fields (network + subnet + gateway + bundle_ip + daemons_csv + environment + volumes). Wiring it up from the inner Plans (PipelockProxyPlan, EgressPlan, GitGatePlan, SupervisePlan) is chunk 2d's job; this module is the docker-argv surface only. Pinning the bundle IP via `docker run --ip <bundle-ip>` is what makes smolvm's TSI allowlist (`<bundle-ip>/32`) safe to compute at prepare time — without pinning, we'd have to inspect the assigned IP after start and feed it back into the Smolfile. Idempotent semantics where it matters: `create_bundle_network` treats "already exists" as success, `remove_bundle_network` + `stop_bundle` treat "no such ..." as success. Other failures die / warn depending on whether the launch flow can recover. Tests: - 15 unit cases (mocked subprocess.run): argv shape for create / remove / start / stop, idempotent paths, host-env inheritance to docker run subprocess. - 1 integration case (real docker daemon, gated on docker available + not GITEA_ACTIONS): end-to-end bringup of an empty-daemons bundle on a 192.168.211.0/24 bridge, confirms the container lands at the pinned IP. Skipped if the claude-bottle-sidecars:latest image isn't built (operator hasn't run a docker bottle yet). 546 unit tests passing. Real-docker bundle bringup green locally. Launch wiring + provisioning + PRD 0022 acceptance probes land in chunk 2d. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

feat(smolmachines): smolvm subprocess wrapper (PRD 0023 chunk 2b)
claude_bottle/backend/smolmachines/smolvm.py — one thin Python
function per smolvm CLI subcommand the launch flow needs:
- pack_create(image, output) → smolvm pack create
- machine_create(name, from_path,
smolfile) → smolvm machine create
- machine_start(name) → smolvm machine start
- machine_stop(name) → smolvm machine stop
- machine_delete(name) → smolvm machine delete -f
- machine_exec(name, argv, env,
workdir, timeout) → smolvm machine exec
- machine_cp(src, dst) → smolvm machine cp
- is_available() → shutil.which check
The wrapper hides the CLI's inconsistent name-flag style
(positional NAME on create/delete, --name on start/stop/exec/
status) behind a uniform `name=` kwarg.
Two return shapes:
- SmolvmRunResult (returncode + stdout + stderr) from
machine_exec, because callers care about the in-VM
command's exit code.
- Raises SmolvmError on non-zero for all other commands;
failure to create/start/stop a VM is fatal to the launch
flow, not branched on.
Tests:
- 15 unit cases mocking subprocess.run, covering argv shape
per subcommand (the --name vs positional inconsistency
locked down), SmolvmError on non-zero for non-exec paths,
SmolvmRunResult passthrough on exec, empty-path cp no-op.
- 2 integration cases against the real smolvm binary
(gated on Darwin + smolvm on PATH + not GITEA_ACTIONS):
smolvm --help responds, machine ls --json parses as a
list (the contract chunk 4's list_active will consume).
531 unit tests passing. Real-smolvm smoke green locally.
Bundle bringup + launch wiring + the localhost-reach /
egress-port-bypass probes land in chunks 2c + 2d.

feat(smolmachines): rewrite Smolfile to smolvm 0.8.0 schema + drop gvproxy (PRD 0023 chunk 2a)
First sub-PR of chunk 2: rewrite the renderer chunk 1 shipped to match smolvm 0.8.0's actual Smolfile shape, delete the dead gvproxy renderer + its tests, simplify the prepare flow now that there's no gvproxy socket + no loopback-port allocation. Smolfile renderer: - Old shape (under the abandoned gvproxy design): name = ..., command = [...], [[net]] attachment = "unixgram", socket = "...". - New shape (smolvm 0.8.0): env = [...] (sorted K=V pairs), [network] allow_cidrs = ["<bundle-ip>/32"]. Nothing else. image / entrypoint / cmd come from the .smolmachine artifact built in chunk 2b; cpus / memory left at smolvm defaults. - Tests assert no leakage of TSI's --outbound-localhost-only or the old gvproxy/unixgram keys. util.py: - smolmachines_gvproxy_subnet → smolmachines_bundle_subnet, returning (subnet, gateway, bundle_ip). bundle_ip is always at .2 (gateway .1); subnet is /24, third octet derived from the slug hash, skipping the docker-default 17 to avoid the common 192.168.17.x collision. - allocate_loopback_port: deleted. The bundle gets a pinned docker IP now; the agent dials that IP directly through TSI. - smolmachines_preflight: dropped the gvproxy check; only smolvm is required. prepare.py: - Drops the gvproxy.yaml render + the loopback port allocation + the gvproxy_socket field on the plan. - Derives subnet / gateway / bundle_ip from the slug and populates the new SmolmachinesBottlePlan fields. - Agent env now uses IP-literal URLs (http://<bundle-ip>:8888 etc) since the guest will have no DNS resolver inside TSI's allowlist. bottle_plan.py: - Old fields: gvproxy_config_path, gvproxy_socket, gvproxy_subnet, gvproxy_gateway, host_port_map. - New fields: bundle_subnet, bundle_gateway, bundle_ip, smolfile_path. (smolmachine artifact path lands in chunk 2b.) Net: -410 lines. Full unit suite: 516 passing. The VM lifecycle + bundle bringup + launch wiring + smoke tests land in chunk 2b.

refactor(backend): extract shared print_multi for plan preflights
Addresses PR #62 review comments on claude_bottle/backend/smolmachines/bottle_plan.py: - Lift the multi-value label printer (was a nested helper inside DockerBottlePlan.print) into a new module claude_bottle/backend/print_util.py:print_multi. Both backends use it for env / skills / git / egress lines. - Strip the three smolmachines-preflight lines the review flagged: the gvproxy subnet line, the smolfile path line, and the gvproxy-config path line. Internal detail — operators see the agent / env / skills / bottle / git / egress that already matter on the docker side, and nothing else. - Add `git → upstream` to the smolmachines git output to match what's useful at preflight time (the docker version shows upstream_host:port; this is similar shape). Leaves the slug=spec.identity-or-mint pattern alone pending a reply on PR comment #432 — the docker backend uses the same pattern to preserve identity across `resume`, so dropping it would silently break the resume path once smolmachines launch lands.

feat(smolmachines): backend skeleton + Smolfile/gvproxy renderers (PRD 0023 chunk 1)
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.
