Extends the preserve-on-capability-block design to also preserve
state on agent crash, and snapshots the transcript on every
teardown so any resume (crash or capability-block) gets a warm
claude session — not a cold start.
- capability_apply: rename _snapshot_transcript → snapshot_transcript
(public; reused below). No behavior change in the capability path.
- cli/start.py: capture bottle.exec_claude's exit code; while the
container is still alive (inside the launch context):
* always snapshot_transcript(identity)
* if exit_code != 0, mark_preserved(identity)
Then the existing _settle_state runs after teardown.
Now the preservation matrix is:
exit 0 (clean) → snapshot + cleanup state
exit ≠0 (crash, Ctrl-C) → snapshot + preserve + show resume hint
capability-block → (already snapshotted/preserved by apply
before teardown; this path is a no-op
because the container is already gone
by the time exec_claude returns)
snapshot_transcript is best-effort — capability-block's earlier
snapshot is not clobbered when the container is already torn down,
and a missing /home/node/.claude is a warn + skip.
Tested behavior: clean exit doesn't preserve, non-zero exit
(including SIGINT/130 and SIGKILL/137) preserves; empty identity
no-ops both helpers.

Previously every bottle launch left ~/.claude-bottle/state/<identity>/
behind forever — metadata.json on every run, plus per-bottle
Dockerfile + transcript snapshot on capability-block rebuilds. The
metadata accumulated debris across launches; the only state worth
keeping was the capability-block rebuild bundle.
Make cleanup the default; preserve only on capability-block.
- bottle_state.py: .preserve marker helpers (mark_preserved,
is_preserved, clear_preserve_marker, preserve_marker_path) +
cleanup_state(identity) that rm -rf's the per-bottle dir.
- capability_apply.apply_capability_change writes mark_preserved
before teardown so cli.py's session-end cleanup keeps the dir.
- prepare.py clears any leftover marker at launch (start or resume),
so a marker from a prior capability-block doesn't keep state
alive past a subsequent normal session-end.
- cli/start.py runs the cleanup decision AFTER the launch context
closes: if is_preserved → print resume hint; else cleanup_state.
The resume hint moves out of the launch with-block (was previously
printed unconditionally — would have misled the operator about
whether state was actually kept).
Future-proof: cli.py never persists state speculatively. If the
agent wants to be resumable, it has to go through capability-block.

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.
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.

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.
'bottles' was the package name when it held a single Bottle Protocol;
since we added BottlePlatform / BottlePlan / BottleCleanupPlan and
made it the home of platform dispatch, 'platform' describes the
package better. The 'bottle' concept (and the manifest field) stays.
CLI imports update from ..bottles to ..platform; internal relative
imports inside the package survive the rename unchanged. Git
detected all 7 file renames.
- Add BottlePlan (frozen dataclass + ABC) with spec, stage_dir, and an
abstract `print(*, remote_control)` method.
- DockerBottlePlan now inherits from BottlePlan; spec/stage_dir come
from the base, Docker-specific fields stay on the subclass.
- Move BottleSpec from bottles/docker.py to bottles/__init__.py so the
cross-platform types live together. docker.py pulls them via
`from . import ...`.
- Move show_plan from cli/start.py to `DockerBottlePlan.print`. Caller
becomes `plan.print(remote_control=...)`. The CLI no longer reads
any Docker-specific fields.
- BottlePlatform.prepare is now typed `Callable[..., BottlePlan]`.
cmd_start drops ~46 more lines.
The spec is intent-only and platform-agnostic — only the plan carries
Docker-specific fields. Drop the 'Docker' prefix and re-export from
claude_bottle.bottles so callers see it as cross-platform.
The Docker factory had absorbed live container ops but left the
host-side prep (image-name resolution, container-name collision
retry, pipelock yaml generation, env_resolve writes, host
validation) in cli/start.py. That kept ~half the Docker-specific
logic outside the abstraction.
Split the factory into two phases:
prepare_docker_bottle(spec, stage_dir=...) -> DockerBottlePlan
Resolves names, validates skills/SSH, writes scratch files.
No Docker resources created yet.
launch_docker_bottle(plan) -> ContextManager[Bottle]
Builds image, creates networks, boots pipelock, runs the
agent container, provisions files. Teardown on exit.
DockerBottleSpec shrinks to intent-only inputs (manifest, agent
name, --cwd flag, user_cwd, forward_oauth_token). The CLI no longer
references docker_mod, pipelock, skills, ssh, or env_resolve.
get_bottle_factory becomes get_bottle_platform returning a
BottlePlatform with .prepare and .launch — one selectable thing per
platform.
The Bottle handle now remembers the in-container prompt path and
adds --append-system-prompt-file to claude's argv when present, so
the CLI no longer needs to know the path.
cmd_start: ~148 lines down from 229. Tests pass; dry-run output
byte-identical.
Introduce claude_bottle/bottles/ with a Bottle Protocol and a
get_bottle_factory() that dispatches on CLAUDE_BOTTLE_PLATFORM
(default "docker"). Move every Docker-specific subprocess.run call
from cli/start.py, plus the orchestration of build, networks, the
pipelock sidecar, container launch, and per-container provisioning
(prompt, skills, ssh, .git), into create_docker_bottle.
Drop bottles[].runtime from the manifest schema. Auto-detect whether
gVisor is registered with the daemon and pass --runtime=runsc when it
is; the preflight shows the resolved runtime so the choice is visible.
Manifests still carrying 'runtime' get a clear error pointing at the
auto-detect behavior, rather than silent ignore.
Out of scope: cli/cleanup.py and cli/list.py still call docker
directly. They enumerate active bottles across the host, which is a
separate concern from "create a bottle" and is left for a follow-up
that introduces a list_active/cleanup primitive on the factory.
Replace the TypedDict + 14 manifest_* free functions with frozen
dataclasses (SshEntry, BottleEgress, Bottle, Agent, Manifest) carrying
their own validators and constructors. Call sites import Manifest and
chain attribute access; the manifest_* helpers and manifest_validate
are gone.
Behavior changes worth flagging:
- Agent.bottle is now required (was optional with a "(none)" fallback).
Manifest.from_json_obj dies if any agent lacks a 'bottle' field or
references an undefined bottle, where previously start.py raised the
error lazily for the specific agent being launched.
- ssh.py now takes SshEntry instances; Host/IdentityFile shape checks
moved upstream into Manifest construction, leaving only the IdentityFile
filesystem-existence check in ssh_validate_entries.
- pipelock_bottle_allowlist's per-element string check is dropped — the
Manifest validator enforces it at load.

Bottles can now set "runtime": "runsc" to launch the agent container
under gVisor instead of runc, adding a userspace syscall barrier
between the agent and the host kernel. Default is runc (Docker
default). Pipelock stays on the default runtime per the research doc's
minimum-diff prescription.
The launcher verifies runsc is registered with the daemon before
launch, surfaces the runtime in the preflight plan, and dies with an
install pointer (and a macOS-not-supported note) when runsc is
requested but unavailable.

One file per subcommand under claude_bottle/cli/, with shared constants
and the tty helper in _common.py and dispatch in __init__.py. The
public import (from claude_bottle.cli import main) is unchanged, so
the root cli.py entrypoint and the test suite see no surface change.
