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.
DockerBottleBackend now instantiates a DockerGitGate alongside
DockerPipelockProxy and DockerSSHGate; the prepare step lifts
bottle.git into a GitGatePlan stored on DockerBottlePlan, and
launch starts/stops the sidecar in the same ExitStack as the
other two (only when bottle.git is non-empty).
bottle_plan.print now surfaces git remotes and per-upstream gate
forwards in the y/N preflight; to_dict adds git_remotes and
git_gate keys to the dry-run JSON payload for CLI consumers.
PRD: docs/prds/0008-git-gate.md
PRD 0007: thread the DockerSSHGate through the bottle lifecycle.
- DockerBottlePlan gains gate_plan: SSHGatePlan.
- prepare.resolve_plan accepts a gate and renders its entrypoint
script next to the pipelock yaml.
- launch.launch starts the gate sidecar after pipelock (so it's on
the same internal + egress networks) and registers its stop in
the ExitStack. Skipped when the bottle has no ssh entries.
- DockerBottleBackend instantiates DockerSSHGate alongside the
pipelock proxy.
- bottle_plan.print + to_dict surface the upstream table so
--dry-run shows the per-host listen-port mapping.
ssh_config provisioning still points at pipelock; that swap lands
in the next commit so this one stays a pure wiring change.
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.

Move the resolution, bring-up, and orphan-cleanup logic out of
backend.py into three topic-named modules. DockerBottleBackend becomes
a thin façade that wires the per-instance pipelock proxy and the
provision orchestrator into the free functions.
backend.py drops from ~360 to ~70 lines and each topic now reads
end-to-end in one place. Mirrors the existing provision/ split.

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().

Avoids cross-instance state via class attribute; the proxy is now
constructed in __init__ alongside its owning backend.

ResolvedEnv.forwarded now carries name->value pairs instead of names
whose values had been side-loaded into os.environ. The Docker backend
collects the dict (plus the renamed OAuth token) and passes it via
subprocess.run(env=...) so docker run -e NAME forwards by-name from
the child's environment, not the parent's.
Values are excluded from the dataclass repr (forwarded on ResolvedEnv,
forwarded_env on DockerBottlePlan) so accidental logging cannot leak
secret or interpolated values.

Silences pylint W1510 / ruff PLW1510 across the codebase. The choice
at each site reflects existing intent:
- check=True where the caller implicitly trusts success (docker ps /
network ls returning stdout, docker build, exec chown/chmod inside
provisioners).
- check=False where the caller inspects .returncode (race-retry on
docker run, pipelock sidecar lifecycle, network plumbing, exec_claude
propagating the session's exit code, best-effort cleanup paths).
No behavior change; check= defaults to False so the False sites are
semantically identical.
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.
Previously prepare wrote two on-disk artifacts that launch consumed:
agent.env (NAME=VALUE) and docker-args (paired -e\nNAME\n lines), with
launch parsing the second back into argv. Docker requires the literals
file on disk for --env-file, but the args-file round-trip was a pure
serialize/deserialize trip with hand-rolled line pairing logic.
Drop docker-args entirely. Pass forwarded names as a structured
tuple[str, ...] field on DockerBottlePlan; launch iterates it directly
to extend docker_args. _write_env_files becomes _write_env_file (only
the literals file remains).
Both prepare-time probing and launch-time race-retry generated the
same `<base>, <base>-2, ..., <base>-N` sequence with their own copies
of the suffix arithmetic and the 99-cap. Extract the candidate stream
into docker/util.container_name_candidates and have both call sites
walk it; each keeps its own predicate (probe vs. retry).
Also bumps the cap into a named constant (MAX_CONTAINER_SUFFIX) so
the two error messages can't drift.
Previously _run_agent_container set os.environ["CLAUDE_CODE_OAUTH_TOKEN"]
deep inside the launch path and added a one-off `-e` pair to docker_args,
which was the only env var to bypass the resolved.forwarded flow used
for everything else.
Move the os.environ mutation + name registration into prepare, right
after resolve_env, so the OAuth token rides the same forwarded-by-name
mechanism as secrets and interpolated entries. _run_agent_container
loses the special case entirely.
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.
Replace the manual state-dict + per-resource branching teardown in
DockerBottleBackend.launch with an ExitStack: each resource registers
its own cleanup callback at the moment it's created, and stack.close()
unwinds in LIFO order. The previous form had to hand-coordinate four
nullable slots and re-check existence for the container; ExitStack
encodes the same semantics declaratively.
PipelockProxy.prepare now accepts (bottle, slug, stage_dir) and derives
the yaml_path itself, so callers don't need to know the filename.
DockerBottleBackend.prepare_proxy becomes a one-line wrapper whose only
caller already has bottle and slug in scope, so it's inlined and
deleted.
resolve_env_into(...) becomes resolve_env(manifest, agent) -> ResolvedEnv
(forwarded names + literals). The docker backend now owns env-file /
argv serialization and the --env-file newline check. Also drops stray
Docker references from manifest.py, pipelock.py, util.py, and trims
the duplicated command list from cli.py's docstring (usage() in
claude_bottle/cli/__init__.py is now the only listing).
Module name aligns with the others (manifest, pipelock, network,
log) — nouns/noun-y, not verb phrases. The function name now reads
naturally at the call site: resolve_env_into(manifest, agent,
env_file, args_file).
New file claude_bottle/backend/util.py for cross-backend host-side
helpers:
host_skill_dir(name) — resolves $HOME/.claude/skills/<name>
docker/util.py gains:
docker_exec_root(container, argv) — `docker exec -u 0` wrapper used
by SSH provisioning
DockerBottleBackend drops the two methods that wrapped these
(`_host_skill_dir`, `_docker_exec_root`) — they had no instance state
and just lived on the class for organizational reasons. Call sites
now use the imported functions directly.
Matches the allowlist-resolution helpers' shape: the caller resolves
the bottle once and passes it in. Signature drops from
(manifest, bottle_name, slug, yaml_path) to (bottle, slug, yaml_path).
DockerBottleBackend.prepare_proxy uses manifest.bottle_for(agent_name)
to get the bottle directly. Tests pass fixture.bottles[name].
prepare's docstring also explains what `slug` is: the lowercased,
hyphen-normalized agent identifier used as the suffix in every
per-agent resource name (agent container, pipelock container, the
internal/egress networks). It's stored on the plan so start can
derive the sidecar's container name.
Top-level pipelock.py drops the Manifest import — no longer used.
The three slug-based naming helpers were nominally on pipelock.py but
each assumed a Docker container topology (the container name is
'claude-bottle-pipelock-<slug>', the proxy URL uses that container
name). Move them next to DockerPipelockProxy:
pipelock_container_name -> claude-bottle-pipelock-<slug>
pipelock_proxy_url -> http://<container>:<port>
pipelock_proxy_host_port -> <container>:<port>
backend.py imports them directly from .pipelock; the orphan-cleanup
test imports container_name from the same place.
PipelockProxy becomes an ABC with the platform-agnostic
prepare/_build_pipelock_yaml as concrete methods and start/stop as
abstract. Docker-specific sidecar lifecycle moves to a new sibling
file:
claude_bottle/backend/docker/pipelock.py
DockerPipelockProxy(PipelockProxy) — implements start (docker
create/cp/network connect/start) and stop (docker inspect/rm -f).
DockerBottleBackend._proxy is now a DockerPipelockProxy instance.
Tests that previously instantiated PipelockProxy() directly switch to
DockerPipelockProxy() (the base is no longer constructable).
Every function in the 'Allowlist resolution' section was doing
`manifest.bottles[bottle_name].X` as its first move. Push the lookup
to the caller and have each helper take a resolved Bottle:
pipelock_bottle_allowlist
pipelock_bottle_ssh_hostnames
pipelock_bottle_ssh_trusted_domains
pipelock_bottle_ssh_ip_cidrs
pipelock_effective_allowlist
pipelock_allowlist_summary
PipelockProxy._build_pipelock_yaml resolves bottle once at the top
and passes it through; DockerBottleBackend.prepare already had the
bottle in scope and now uses it directly. Tests pass the resolved
bottle from each fixture.
ProxyPlan -> PipelockProxyPlan, with two additional fields populated
in launch: internal_network, egress_network (default ""). prepare
fills yaml_path + slug; launch uses dataclasses.replace to populate
the networks before calling start.
pipelock_start -> PipelockProxy.start(plan). Reads yaml_path, slug,
internal_network, egress_network off the plan. Returns the resolved
container name.
pipelock_stop -> PipelockProxy.stop(proxy_target). Takes the resolved
container name directly (the value that start returned); no longer
needs to know about slugs or naming conventions.
Backend launch passes the running container name (state["pipelock"])
to stop. Test for stop's idempotency uses pipelock_container_name to
construct the proxy_target.
Add a frozen ProxyPlan dataclass to pipelock.py (currently one field:
yaml_path; kept as a class so future proxy-level state has a home).
- prepare_proxy(spec, stage_dir) now returns pipelock.ProxyPlan
instead of a raw Path.
- DockerBottlePlan replaces pipelock_yaml_path + pipelock_yaml_filename
with a single proxy: ProxyPlan field.
- launch reads plan.proxy.yaml_path.parent / .name when calling
pipelock_start. Eventually pipelock_start should just take a Path
but that's a separate change.
prepare_proxy(spec, stage_dir) -> Path now decides where the
pipelock yaml lives inside stage_dir (currently 'pipelock.yaml'),
writes it via PipelockProxy.prepare, and returns the resolved path.
The caller (prepare) drops its 'pipelock_yaml_filename' /
'pipelock_yaml = stage_dir / filename' setup and just consumes the
returned Path; the plan's pipelock_yaml_filename is derived from
.name on the path.
The YAML generation now lives on PipelockProxy.prepare(manifest,
bottle_name, yaml_path) in claude_bottle/pipelock.py. The class is the
natural home for any future proxy-level state.
DockerBottleBackend keeps an instance as a class attribute
(_proxy = PipelockProxy()) and its prepare_proxy becomes a thin
delegation. A future backend that wants a different egress proxy
(or none) plugs in its own strategy.
Tests retarget at the new home — PipelockProxy.prepare gets the
content-shape assertions; the sidecar smoke test uses the class
directly too. Same coverage.
The yaml generation logic moves wholesale onto DockerBottleBackend
where it's used. pipelock_write_yaml is deleted; pipelock.py keeps
the allowlist resolution helpers (still called by prepare_proxy and
by pipelock_allowlist_summary).
The pipelock_start error message that referenced "pipelock_write_yaml
must run first" now says "backend.prepare_proxy must run first."
tests/test_pipelock_yaml.py rewritten to drive DockerBottleBackend().
prepare_proxy(spec, yaml_path); test_pipelock_sidecar_smoke.py call
site updated similarly. Same coverage at the new location.
_expand_tilde was a path-string helper on DockerBottleBackend but
nothing about it was Docker-specific — any future backend reading
host paths from manifest entries would want it. Lift to
claude_bottle/util.py (sibling of log.py / manifest.py) as a public
expand_tilde() function. Docker-specific primitives stay in
claude_bottle/backend/docker/util.py.
Mirrors the skills.py absorb. ssh_validate_entries -> validate_ssh_entries
(called from prepare); ssh_setup body -> provision_ssh; the
_docker_exec_root and _expand_tilde helpers become private methods on
the backend.
The detailed isolation-model docstring from the old module moves to
provision_ssh, where the code lives now. ssh.py deleted.
The whole module folds into two methods on the backend:
validate_skills(skills) — called from prepare; fails loudly when
a named skill is missing on the host so
the user doesn't get a y/N for a plan
that's already known to break.
_host_skill_dir(name) — private helper used by both
validate_skills and provision_skills.
skills.py is deleted; the four prior functions (host_skill_dir,
host_skill_exists, require_host_skill, skills_validate_all) collapse
into the two above without losing the pre-y/N validation.
The copy logic was Docker-specific (docker exec mkdir / rm -rf,
docker cp); it had no reason to live in a top-level skills module.
Pull the body into DockerBottleBackend.provision_skills.
skills.py keeps the host-side discovery + validation
(host_skill_dir, host_skill_exists, require_host_skill,
skills_validate_all). The orphaned CONTAINER_HOME /
CONTAINER_SKILLS_DIR constants and the now-unused subprocess + info
imports are removed.
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.
Four symmetric provision sub-methods now: provision_prompt,
provision_skills, provision_ssh, provision_git. Each self-gates with
an early return; provision is pure orchestration.
provision now orchestrates three focused sub-methods. Each sub-method
self-gates: provision_ssh is a no-op when the bottle has no SSH
entries; provision_git is a no-op when --cwd was not set. The prompt
copy + chown always runs (so the path always exists in-container);
the return is gated on whether the agent has a non-empty prompt.
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.
