Promote the user-switch from a hardcoded `node` to a keyword arg
so callers can opt into root (or any other user) when needed.
Default stays `node` — matches the docker image's USER and the
smolmachines runuser default.
Lifts the change through the base ABC, docker, and smolmachines
backends:
- Base: `def exec(self, script, *, user="node")`.
- Docker: adds `-u <user>` to `docker exec` (no-op when user is
node, the image's default).
- Smolmachines: `runuser -l <user> -c <script>` — `runuser -l
root` is the trivial no-op form when the caller asked for root.

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.

The manifest key is `egress:` now; finish the rename so the rest of
the codebase matches. Files (Dockerfile.egress, claude_bottle/egress.py
etc.), classes (Egress, EgressConfig, EgressRoute, EgressPlan,
DockerEgress), constants (EGRESS_HOSTNAME, EGRESS_ROUTES, ...),
container name prefix (claude-bottle-egress-*), docker network alias
(egress), the introspection host (_egress.local), the MCP tool IDs
(egress-block, list-egress-routes), and the preflight label all drop
the `-proxy` suffix.
Companion to the compact preflight in #31 — the JSON format was
the structured alternative to the verbose text summary. With the
new compact text already on screen, no consumer was using the
JSON shape, and the abstract `BottlePlan.to_dict` was the
biggest piece of API surface no one is implementing against.
Removed:
- `--format` CLI flag from `start` and `resume`.
- `output_format` kwarg from `_launch_bottle`.
- `BottlePlan.to_dict` abstract method.
- `DockerBottlePlan.to_dict` (60-line dict builder).
- The `_PlanView` dataclass — `print` was the only remaining
caller, so the env-name computation is inlined.
- `tests/integration/test_dry_run_plan.py` (JSON-shape
integration test).
- `tests/unit/test_cli_start_format.py` (flag-conflict unit).
Plan-introspection is still possible by reading the
`DockerBottlePlan` dataclass directly — fields like `image`,
`container_name`, `stage_dir`, `use_runsc` are all there. Tooling
that needs a stable wire shape can JSON-serialize the dataclass
themselves.
411 unit + integration tests pass.

Partial revert of fa06a3a. The role + agent-side provisioner felt
overengineered: anthropic-base-url + npm-registry's only realistic
host values match the tool defaults, so the role tags drove no-op
dotfile writes most of the time. If non-default npm registry / tea
config is needed in a future bottle, we can ship it through a more
direct mechanism then.
What stays from fa06a3a:
- Universal HTTPS git-push block in the egress-proxy addon
(`is_git_push_request` in egress_proxy_addon_core, called from
the request hook before route matching; 403s git-receive-pack
regardless of route). This is the security backstop so git-gate
remains the only outbound write path; PR #29 keeps it.
What gets reverted:
- `Role` field on EgressProxyRoute (manifest + runtime).
- `EGRESS_PROXY_ROLES` + `EGRESS_PROXY_SINGLETON_ROLES` constants
and singleton-role validation.
- `backend/docker/provision/egress_proxy.py` (npmrc + tea config).
- `provision_egress_proxy` slot in `BottleBackend.provision`.
- `prepare.py`'s role-based ANTHROPIC_BASE_URL detection (back to
the token_ref="CLAUDE_CODE_OAUTH_TOKEN" auto-detect).
- Manifest + provisioner tests for the above.
355 unit + 24 integration tests pass.

Two related fixes on top of PR #29's chunk-2 cutover:
1. Universal HTTPS git-push block in the egress-proxy addon
(`is_git_push_request` in egress_proxy_addon_core, called from the
mitmproxy request hook before route matching). 403s any
`/git-receive-pack` or `info/refs?service=git-receive-pack` —
defense in depth so git-gate (PRD 0008) remains the only outbound
path for writes, gitleaks-scanned by its pre-receive. Replicates
cred-proxy's `is_git_push_request` behavior.
2. Restored agent-side role provisioner. Brings back `Role` on
EgressProxyRoute (manifest + runtime) with three roles —
`anthropic-base-url`, `npm-registry`, `tea-login`. Singleton
constraint on the first two carries over from cred-proxy.
`git-insteadof` is intentionally absent (option 1 above handles
the push-bypass concern, and the canonical-URL rewrite has no
function when egress-proxy is on HTTPS_PROXY).
The provisioner (`backend/docker/provision/egress_proxy.py`):
- `~/.npmrc` registry= the canonical upstream URL.
- `~/.config/tea/config.yml` logins[] entry per tea-login route.
- `ANTHROPIC_BASE_URL` env set in prepare.py based on the
anthropic-base-url role (was a token_ref="CLAUDE_CODE_OAUTH_TOKEN"
check in this PR's earlier draft — the role marker is cleaner
and matches the cred-proxy precedent the user wants kept).
All three dotfile values point at canonical upstream URLs; the
agent's HTTPS_PROXY=egress-proxy routes them through the proxy
automatically.
Tests: 11 new role-validation tests, 11 new provisioner-render tests,
the chunk-1 manifest fixture exercise role=anthropic-base-url. 400
tests pass (was 376).

Hard cutover. cred-proxy is deleted; egress-proxy is now the agent's
HTTP_PROXY (when routes are declared) with pipelock on its outbound
leg. Two per-bottle CAs are minted: egress-proxy's (agent trust
store) and pipelock's (egress-proxy's outbound trust store).
Manifest:
- `bottle.cred_proxy` → hard error with a migration recipe.
- `bottle.egress_proxy` is the new shape (PRD 0017 chunk 1).
- CredProxy* types + role validators removed.
Wiring:
- launch.py: `egress_proxy_tls_init` mints the egress-proxy CA
(cert+key concat for mitmproxy + cert-only for agent trust);
`DockerEgressProxy.start` docker-cps both CAs in, sets
`HTTPS_PROXY=pipelock` + `EGRESS_PROXY_UPSTREAM_CA` so mitmdump
trusts pipelock's MITM. Agent's HTTP_PROXY points at
egress-proxy when routes exist, else falls back to pipelock
(no-routes bottles unchanged).
- prepare.py / backend.py: `cred_proxy` arg → `egress_proxy`;
sidecar-orphan probe + plan field + dashboard view all
renamed.
- provision_ca: selects the egress-proxy CA when present, else
pipelock's (filename renamed to claude-bottle-mitm-ca.crt).
- bottle.provision: cred-proxy dotfile rewrites (~/.npmrc,
~/.gitconfig insteadOf, tea config) are gone — HTTP_PROXY
catches everything respecting it.
Pipelock helpers:
- `pipelock_token_hosts` → `pipelock_route_hosts` (now reading
egress_proxy.routes).
- cred-proxy hostname auto-allow → egress-proxy hostname
auto-allow.
- Anthropic seed-phrase workaround now triggers when an
egress_proxy route targets api.anthropic.com (was based on the
cred-proxy `anthropic-base-url` role).
Dockerfile.egress-proxy:
- Entrypoint conditionally passes
`--set ssl_verify_upstream_trusted_ca=$EGRESS_PROXY_UPSTREAM_CA`
(via the `${VAR:+...}` shell expansion) so standalone runs without
a mounted pipelock CA still boot.
- mkdirs `/home/mitmproxy/.mitmproxy` ahead of `docker cp`.
Deleted: claude_bottle/{cred_proxy,cred_proxy_server}.py,
backend/docker/{cred_proxy,provision/cred_proxy}.py,
Dockerfile.cred-proxy, plus the corresponding unit + integration
tests. backend/docker/cred_proxy_apply.py stays as a stub for
chunk 3 to rewrite (its container-name + routes-path constants
are inlined so it survives without the deleted module).
Test changes:
- test_pipelock_allowlist rewritten against egress-proxy routes
+ the new `pipelock_route_hosts`.
- test_manifest_md_load + test_pipelock_yaml + test_yaml_subset
fixtures migrated to the `egress_proxy: { routes: [...] }`
shape.
- test_supervise_sidecar's round-trip test switched from
`dashboard.approve` to `dashboard.reject`: the approval-apply
path on cred-proxy-block proposals hits a deleted sidecar in
chunk 2's transitional state. Chunk 3 restores the approval
test once the remediation flow is retargeted at egress-proxy.
376 tests pass (was 427; net delta is removed cred-proxy tests).

The supervise sidecar (PRD 0013) has been serving MCP at
http://supervise:9100/ since it landed, but the in-bottle Claude
Code had no `.mcp.json` or settings pointing there — so the agent
couldn't actually call cred-proxy-block / pipelock-block /
capability-block as tools. To exercise the flow you had to curl
the sidecar from a sibling container.
This closes that last mile.
- claude_bottle/backend/docker/provision/supervise.py (new):
provision_supervise(plan, target) writes
~/.claude/settings.json into the running agent container with an
mcpServers.supervise entry of type http pointing at the
per-bottle sidecar. No-op when bottle.supervise is False.
- BottleBackend.provision orchestrator gains provision_supervise as
the last step (after CA, prompt, skills, git, cred-proxy). Default
impl is a no-op so non-Docker backends aren't forced to implement it.
- DockerBottleBackend wires it through to the new module.
- Test covers the rendered settings shape so a future regression in
the MCP entry format would surface in unit-level CI.
To test the full flow end-to-end now:
./cli.py start <agent> --cwd # agent's claude sees supervise
# agent calls cred-proxy-block via MCP
./cli.py dashboard # approve
./cli.py resume <identity> # restart with new capabilities
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Replaces the cwd-hash identity with a random 5-char base36 suffix
per launch, so two simultaneous `start <agent>` invocations against
the same cwd no longer collide on container names. Each launch is
its own bottle.
State carries metadata: every prepare step writes
~/.claude-bottle/state/<identity>/metadata.json with the
(agent_name, cwd, copy_cwd, started_at) the bottle was launched
with. The new `cli.py resume <identity>` reads this metadata and
re-launches a bottle pinned to the same identity — picking up the
per-bottle Dockerfile (from a prior capability-block apply) and
the transcript snapshot under the same state dir.
- bottle_state.py: bottle_identity(agent_name) drops the cwd param
and gains a random suffix; BottleMetadata dataclass +
read/write/metadata_path helpers.
- BottleSpec gains an optional identity field — resume sets it to
pin the identity; start leaves it empty so prepare mints fresh.
- prepare.py: writes metadata at launch time; uses spec.identity if
provided (resume) else bottle_identity(agent_name) (fresh start).
- start.py: extracted _launch_bottle from cmd_start so resume can
share the launch core; prints `./cli.py resume <identity>` hint
at session end.
- cli/resume.py (new): reads metadata, reconstructs BottleSpec
with the recorded identity + cwd, delegates to _launch_bottle.
Errors clearly when no state exists for the given identity.
- cli/__init__.py: registers `resume` in COMMANDS + usage.
- dashboard.py: capability-block approval status line now appends
the `resume <identity>` hint so the operator can copy-paste the
rebuild command without leaving the TUI.
Closes the rebuild loop in PRD 0016: agent calls capability-block →
operator approves → bottle torn down with state preserved → status
line shows resume command → operator runs it → replacement bottle
boots with the new Dockerfile and prior transcript.

Removes the legacy `CLAUDE_BOTTLE_OAUTH_TOKEN` -> `CLAUDE_CODE_OAUTH_TOKEN`
forward in prepare.py. Bottles that need claude-code to authenticate
must declare a cred_proxy route with role: "anthropic-base-url" — there
is no fallback that hands the token to the agent directly.
Drops the now-dead BottleSpec.forward_oauth_token field, the CLI
setter that read CLAUDE_BOTTLE_OAUTH_TOKEN from the host env at
prepare time, and the forward_oauth_token=False arg in the six
pipelock integration tests.
PRD 0010 and README updated; the dev ~/claude-bottle.json gains an
anthropic-base-url route so the implementer/researcher agents keep
working.
BREAKING: bottles previously relying on the implicit OAuth forward
will now produce an agent environ without any Anthropic credential.
Verified with --dry-run: a bottle with no anthropic-base-url route
yields env_names: [] (no token at all); a bottle that declares the
route yields ANTHROPIC_BASE_URL plus a non-secret placeholder for
CLAUDE_CODE_OAUTH_TOKEN.
- DockerBottleBackend instantiates DockerCredProxy alongside pipelock
and git-gate; threads it through prepare and launch.
- DockerBottlePlan gains cred_proxy_plan; preflight rendering shows
the declared kinds + TokenRefs and to_dict emits a cred_proxy
array matching the routing table.
- prepare.py: when bottle.tokens has an anthropic entry, route the
agent at the proxy via ANTHROPIC_BASE_URL, drop the agent-side
CLAUDE_CODE_OAUTH_TOKEN forward (the token goes to the sidecar's
environ instead, set a non-secret placeholder so claude-code's
startup check passes), and default the telemetry-off env vars.
- launch.py: bring up the cred-proxy sidecar in ExitStack before the
agent container so DNS resolution for `cred-proxy` succeeds on the
agent's first call.
- backend/__init__.py: add provision_cred_proxy to the provision
template (runs after provision_git so it can append to ~/.gitconfig).
- bottle_plan _view: env_names is derived from the forwarded_env dict,
so the preflight reflects the PRD 0010 switch without ad-hoc
branching on spec.forward_oauth_token.
Delete claude_bottle/ssh_gate.py, the DockerSSHGate sidecar,
and the provision_ssh provisioner (~/.ssh/config + ssh-agent
wiring). Unwire the gate from the abstract BottleBackend
(provision orchestration drops the ssh step,
_validate_ssh_entries goes away) and from the Docker backend
(prepare/launch lose the `gate` kwarg, bottle_plan drops the
gate_plan field, dry-run JSON drops the ssh_hosts / ssh_gate
keys, y/N preflight drops the ssh-hosts block). cli/info now
prints declared git remotes instead of ssh hosts. pipelock's
docstring picks up the git-gate framing now that there's no
PRD-0007 boundary to call out.
BREAKING (dry-run JSON): the `ssh_hosts` and `ssh_gate` keys
are gone from `start --dry-run --format=json`. Consumers should
read `git_remotes` / `git_gate` instead.
Each entry pairs a Name (local alias the gate exposes) with an
ssh:// Upstream URL, an IdentityFile the gate uses to push to
that upstream, and an optional KnownHostKey for upstream
host-key pinning. The Upstream URL is parsed at construction
into UpstreamUser/Host/Port/Path so downstream code doesn't
re-parse.
Two cross-validation rules: Names must be unique within a
bottle (each maps to a distinct bare repo), and no git entry's
(host, port) may overlap an ssh entry's (Hostname, Port) — the
same upstream reachable two ways would let a misbehaving agent
route around the gitleaks-bearing git-gate via the L4 ssh-gate.
PRD: docs/prds/0008-git-gate.md
Second step of PRD 0006. With pipelock now doing the bumping, the
agent's TLS library has to trust pipelock's per-bottle CA — or
every CONNECT to api.anthropic.com is a self-signed-cert error.
- BottleBackend.provision gains a non-abstract `provision_ca`
with a default no-op (so non-Docker backends aren't forced to
implement TLS interception) and orchestrates
ca → prompt → skills → ssh → git. CA install runs first so the
agent's trust store is rebuilt before anything else in the
agent makes a TLS call.
- New backend/docker/provision/ca.py: docker-cp's the CA cert
into the agent at /usr/local/share/ca-certificates/...,
`update-ca-certificates`, then emits a one-line stderr log
with the SHA-256 fingerprint (stdlib `ssl` + `hashlib`; no
subprocess for crypto). Module-level constants AGENT_CA_PATH
and AGENT_CA_BUNDLE are imported by launch.py so the env
trio set at docker run time matches the paths the provisioner
writes.
- launch.py: rebinds `plan` after `dataclasses.replace`s on the
pipelock proxy plan so provision_ca (which reads
`plan.proxy_plan.ca_cert_host_path`) sees the populated CA
paths. Three new -e flags on the agent's docker run for the
NODE_EXTRA_CA_CERTS / SSL_CERT_FILE / REQUESTS_CA_BUNDLE trio.
- Dockerfile: adds curl to the apt-get install line. curl
natively respects HTTPS_PROXY and sends CONNECT directly —
the agent doesn't need OS-level DNS for external hostnames
(pipelock resolves them on its side of the bumped tunnel).
This is the "simple HTTPS request" path the earlier turn
needed and Node's stdlib https.request couldn't provide.

Bottle.exec(script) -> ExecResult runs a POSIX shell script inside a
running bottle and returns captured stdout/stderr/returncode. The
Docker impl pipes the script via stdin to `docker exec -i ... sh -s`
so the source never crosses argv.
Two integration tests exercise it end-to-end through the pipelock
sidecar: a Node request to a non-allowlisted host (example.com)
returns 403 from pipelock; a Node CONNECT to an allowlisted host
(raw.githubusercontent.com) is tunneled with 200 Connection
Established. The 200/403 split on each verb is decided by pipelock
itself, isolating the allowlist decision from whatever the remote
might return.

Make BottleBackend.prepare a template method that runs a cross-backend
_validate step (agent exists, named skills present on host, SSH
IdentityFiles resolve) and then delegates to a subclass-implemented
_resolve_plan for backend-specific resolution.
A future backend that overrides _resolve_plan can no longer forget to
validate skills or SSH keys; the validation runs unconditionally via
prepare. Backends with additional preconditions can override _validate
and chain via super().

Adds pyrightconfig.json (strict, Python 3.11) covering cli.py,
claude_bottle/, and tests/. Fixes the 49 strict-mode errors:
- Type DockerBottle.teardown as Callable[[], None].
- ResolvedEnv default_factory uses parameterized list[str] / dict[str, str].
- Erase BottleBackend generics at the registry boundary
(BottleBackend[Any, Any]) since selection is runtime-driven and
callers use the unparameterized interface.
- DockerBottleBackend.launch returns Generator[DockerBottle, None, None];
@contextmanager now flags Iterator returns as deprecated.
- Sidestep cli.list submodule shadowing builtins.list in main()'s argv
annotation via an aliased re-import in cli/__init__.py.
- Cast cfg[...] results in test_pipelock_yaml at the dict[str, object]
boundary.
- Annotate write_fixture's fn parameter and _manifest_with_runtime's
return type.
Parameterize BottleBackend over PlanT (bound to BottlePlan) and
CleanupT (bound to BottleCleanupPlan). DockerBottleBackend declares
itself BottleBackend[DockerBottlePlan, DockerBottleCleanupPlan], which
narrows every method's plan parameter to the concrete type and lets
the six `assert isinstance(plan, DockerBottlePlan)` lines on
launch/cleanup/provision_* go away.
The dict in get_bottle_backend keeps its unparameterized
BottleBackend element type so it can hold heterogeneous backend
specializations.
BottlePlan gains a to_dict method (abstract on the base, implemented
on DockerBottlePlan) returning a JSON-serializable view of the resolved
plan. `cli.py start --dry-run --format=json` prints it to stdout and
exits zero. --format=json without --dry-run is rejected — emitting JSON
during a real launch would race the y/N prompt.
The dry-run integration test now parses the JSON and asserts on
structured fields (agent, bottle, runtime, hosts sorted+deduped, etc.)
instead of regex-matching the human-readable preflight stdout. That
kills the magic-"8 hosts allowed" coupling — adding a new baked
default doesn't break the test.

Template Method pattern. BottleBackend.provision is now concrete and
orchestrates four abstract sub-methods:
provision_prompt -> str | None (only one with a meaningful return)
provision_skills -> None
provision_ssh -> None
provision_git -> None
Each is self-gating: skills/ssh/git short-circuit on empty inputs;
prompt always copies (the path must exist) and returns None when the
agent has no prompt content.
DockerBottleBackend drops its own `provision` (inherited from the
base) and now just implements the four sub-methods. Each sub-method
takes `plan: BottlePlan` (matching the abstract) and asserts
isinstance to narrow to DockerBottlePlan internally, same pattern as
`launch`.
A future fly.io backend implements the four sub-methods; provision
works for it unchanged.
BottleProvisioner had no independent identity — no state, only one
caller, never selected, never crossed a method boundary as data. It
was a method dressed up as a class. Reverting that turn:
- BottleBackend gains an abstract provision(plan, target).
- DockerBottleBackend.provision absorbs the body that lived on
DockerBottleProvisioner.
- backend/docker/provisioner.py deleted.
- BottleProvisioner ABC removed from backend/__init__.py.
- launch now calls self.provision(plan, container) directly.
Net: -1 file, -1 class, -1 ABC. Same behavior; tests pass.
Lift the file-copying-into-the-running-container step out of
DockerBottleBackend._provision_container into its own class. The
backend now holds a DockerBottleProvisioner instance and delegates
the post-launch provisioning to it.
- BottleProvisioner (abstract) in backend/__init__.py with a
`provision(plan, target) -> str | None` method.
- DockerBottleProvisioner (concrete) in backend/docker/provisioner.py
inheriting from the base, narrowing plan to DockerBottlePlan via
isinstance, and carrying the prompt/skills/SSH/.git copy logic
unchanged.
- DockerBottleBackend keeps a class-level DockerBottleProvisioner()
and calls self._provisioner.provision(plan, container) from launch.
_provision_container method removed.
No behavior change.
Across the package:
- claude_bottle/platform/ -> claude_bottle/backend/
- platform/docker/platform.py -> backend/docker/backend.py
- class BottlePlatform -> BottleBackend
- class DockerBottlePlatform -> DockerBottleBackend
- get_bottle_platform() -> get_bottle_backend()
- env var CLAUDE_BOTTLE_PLATFORM -> CLAUDE_BOTTLE_BACKEND
- dict _PLATFORMS -> _BACKENDS
"Backend" is shorter and more established as the term for a
pluggable strategy-pattern implementation. "Platform" was vague
(could mean OS, hardware, cloud) and mildly redundant — Docker is
itself a platform.
The previous PRD section claiming "the Backend protocol was
rejected" referred to a low-level run/exec/cp/network_connect
protocol; the name was never the reason. The PRD is updated to
describe that rejected design by shape rather than by name.
The bottle/agent concepts and the manifest schema are unchanged.
