Addresses review comments 3098, 3099, 3100 on PR #336:
- Add BottleImages(agent, sidecar) dataclass to backend/__init__.py.
Docker/macOS backends use str image refs; smolmachines uses Path
artifacts. Replaces the singular `image` variable from the canonical
pattern in comment 3100.
- Replace _image_stale_checks/skip_stale with public prelaunch_checks().
CLI now calls backend.prelaunch_checks(plan) before backend.launch(plan);
if StaleImageError is raised and the operator confirms, launch proceeds
without re-checking. Removes the while-True/skip_stale retry loop.
- Add abstract _build_or_load_images(plan) -> BottleImages to
BottleBackend. launch() calls it then passes images to _launch_impl.
Each backend implements both methods.
- Fix comment 3098 (macos-container): _build_images is removed.
build_or_load_images() has separate fresh/cached code paths — the
cached path never calls a build helper.
- Update _start_bundle (smolmachines) to accept sidecar_artifact: Path
directly. Sidecar artifact resolution moves to _sidecar_from_path(),
called by build_or_load_images alongside _agent_from_path().
- image_cache: StaleImageError exception + check_stale/check_stale_path (raise instead of warn)
- BottleBackend.launch: template method (skip_stale flag) that calls _image_stale_checks then _launch_impl
- Each backend: _image_stale_checks delegates to a stale_checks() function in its launch module; _launch_impl replaces launch override
- macos_container: adds image_created_at to util, cached-image support in _build_images, stale_checks
- cli/start.py: catches StaleImageError, prompts interactively, retries with skip_stale=True; headless mode dies on it
Review follow-ups for the infra candidate-artifact flow:
1. publish-infra would fail on the first merge to main. The rootfs version now
hashes the dropbear bytes, and build-infra sets BOT_BOTTLE_FC_DROPBEAR to the
staged dropbear — but publish-infra (ubuntu-latest) set none, so _publish_
bundle re-derived the version with a "<missing>" dropbear and rejected the
candidate as "does not match checkout". Download the same firecracker-inputs
dropbear and export BOT_BOTTLE_FC_DROPBEAR in publish-infra (and add
stage-firecracker-inputs to its needs, since it now consumes that artifact).
2. Guard stage-firecracker-inputs with the same fork-PR check as the other
KVM-runner jobs, so a fork PR can't spin the privileged runner (it only
copies a static binary, but keep the posture consistent; it gates the whole
Firecracker chain via needs).
3. ensure_artifact_gz / _publish_bundle read version.txt before checking it
exists — a bundle missing it raised a raw FileNotFoundError instead of the
intended "bundle is incomplete" die. Guard the read (kept before the gz/sha
completeness check so a wrong-version bundle still reports the version
mismatch, not "incomplete").
4. test_infra_artifact.setUp didn't isolate BOT_BOTTLE_INFRA_ARTIFACT_DIR, so
an ambient candidate dir (the coverage job exports one) would send the
registry-pull tests down the local-bundle path. Pin it off in setUp; the
candidate-path cases set it explicitly.

The coverage CI job exports BOT_BOTTLE_INFRA_BUILD=local so the integration
suite builds infra/agent images from source. But that job also runs the unit
suite, and the ambient =local leaked into test_default_pulls_artifact_without_
docker — it drove ensure_built() down the local Docker-build branch, so the
"build_image not called / artifact pulled" assertion failed (build_image
called 3 times).
Pin the var off in that test so it exercises the default pull path regardless
of the runner's ambient env (mirrors test_local_mode_builds_deps_before_infra,
which pins it on). Full unit suite verified green under BOT_BOTTLE_INFRA_BUILD
=local.

Dockerfile.gateway COPYs pyproject.toml into /src and runs pip install
/src, so it is a real input to the baked rootfs. A dependency-only change
previously reused stale artifact versions, potentially booting a rootfs
whose installed packages differed from the current checkout.
Also adds _fake_repo fixture support and a regression test so this input
can't silently drop out of the hash again.

Two lint fixes, both test-only (no effect on the infra artifact version):
- annotate the TestAdoptable / TestKillInfraFirecrackers helper params
(reportMissingParameterType).
- test_docker_test_helpers: read __unittest_skip__ via getattr on the
dynamically-built Case type, matching the sibling assertion — pyright can't
see the attribute the skip decorator adds (reportAttributeAccessIssue).

build_agent_rootfs_dir cached the built rootfs by Dockerfile content alone,
but util.inject_guest_boot then writes util._GUEST_INIT into it. So a fix to
the init — making /tmp world-writable (1777) so the agent can create scratch
dirs / git worktrees there — did NOT bust the cache: the KVM runner kept
reusing a stale agent-<dockerfilehash> rootfs built with the old init, and the
sandbox-escape README-push test kept failing at `git init /tmp/...` with
"Permission denied".
Key the cache on Dockerfile content AND the injected init (_rootfs_digest), so
an init change rebuilds. Self-busting: the new key yields a fresh cache dir, so
no manual cache clear on the runner.

The KVM CI runner now sets BOT_BOTTLE_FC_* for its isolated pool (distinct
iface prefix / orch iface / nft table / IP base), and that env leaks into the
coverage job's test process. Five netpool tests hardcoded the default names
(bbfc*, bot_bottle_fc) and so failed there with e.g. ['bbfc1'] != ['bbci1'].
Assert against netpool's env-driven config instead — slot(i).iface / the
configured prefix — so the tests check the LOGIC regardless of which pool the
host is configured for. The single-source test now compares the parsed
defaults (netpool._DEFAULTS, env-independent) for the module constants, since
IFACE_PREFIX/NFT_TABLE legitimately layer an env override on top.

The infra VM is a per-host singleton that outlives short-lived launchers, so
`ensure_running` adopts it when its control plane is healthy. But it adopted
ANY healthy VM regardless of the code that built it — so after an infra-code
change the old VM kept being adopted and the new code never booted. The only
way to dislodge it was an out-of-band `kill`, which then raced whatever
launched next. On CI this meant every infra change needed a manual VM kill.
Make adoption version-aware:
* boot records the infra-artifact version it booted from in a `booted-version`
marker beside the singleton; `stop` clears it.
* `ensure_running` adopts only when the marker matches the current version
(`_adoptable`); a missing/mismatched marker falls through to stop + reboot.
So a stale VM is replaced automatically on the next launch — no manual kill,
and it's concurrency-safe (the reboot happens under the singleton flock).
Also harden teardown: the PID file drifts after crashes / out-of-band kills,
so `stop` now also reaps any orphaned firecracker still bound to the infra
config path (scoped to that path, so interactive-pool VMs are untouched) —
otherwise a survivor holds the orchestrator TAP and the fresh boot dies with
"tap … Resource busy".

The rootless agent rootfs build can land /tmp as 0755/root-owned, so the
agent (uid 1000 node) can't create scratch dirs there. The sandbox-escape
suite's README-push test does `cd /tmp && git init sandbox-escape-repo` and
died with "cannot mkdir sandbox-escape-repo: Permission denied" — before the
git-gate gitleaks hook could run — so the test read it as a missing hook.
On docker the agent inherits node:22-slim's 1777 /tmp, which is why only the
Firecracker path was affected (and only now that the suite runs end-to-end).
Set /tmp to 1777 in the guest PID-1 init, so every agent VM boots with a
usable /tmp regardless of rootfs perm drift.
Also update the infra-init unit test to assert the gateway launches via the
`bot_bottle.gateway_init` module (matching the prior fix), not a file path.

Two diff-coverage gaps on the ci-kvm-runner branch:
1. bot_bottle/backend/docker/setup.py: the try/except TimeoutExpired
block added in a prior commit had no tests reaching the subprocess
path. Add two tests to TestDockerSetupStatus: one for the success
path (subprocess returns 0) and one for the TimeoutExpired fallback.
2. bot_bottle/db_store.py: the _connection() context manager change in
is_migrated() was never exercised by unit tests (all callers mock
is_migrated() directly). Add test_db_store.py covering the absent-DB,
missing-schema-table, migrated, and behind-schema cases.
On a self-hosted KVM runner the process has a real controlling terminal
so name_color_modal successfully opens /dev/tty and enters a curses
loop waiting for keyboard input, hanging the test indefinitely.
Docker containers (ubuntu-latest runners) don't have a real /dev/tty,
causing an OSError that triggers the existing fallback — this is why
the hang was invisible in ubuntu-latest CI.
Also add timeout=5 to _daemon_reachable() to match the same defensive
fix already applied to docker_available() in tests/_docker.py.

Docker integration tests are already covered by the integration-docker
job on ubuntu-latest. On the KVM runner the Firecracker TAP/nftables
pool conflicts with Docker networking, causing those tests to hang
and the coverage job to never complete.
Add SKIP_DOCKER_TESTS env-var support to docker_available() and set
it for the integration phase of coverage.sh so only Firecracker
integration tests run there.
On the self-hosted KVM runner Docker is on PATH but the daemon socket
is unreachable (firewalled/dropped). subprocess.run(["docker", "info"])
with no timeout hangs indefinitely on a dropped connection, stalling the
coverage job for hours — one hang per @skip_unless_docker()-decorated
class, ~8 per integration suite run.
Add timeout=5 with a TimeoutExpired → False fallback so the check
resolves quickly to "unreachable" rather than blocking.
The sandbox-escape test was unconditionally skipped when GITEA_ACTIONS=true,
which prevented Firecracker orchestration coverage from being measured even
when BOT_BOTTLE_BACKEND=firecracker is set on the KVM runner.
Narrow the skip to: GITEA_ACTIONS=true AND BOT_BOTTLE_BACKEND != firecracker.
When BOT_BOTTLE_BACKEND=firecracker the test is explicitly opted in to run on
the self-hosted KVM runner where the required /dev/kvm + TAP pool exist.

NixOS doesn't populate /bin (no /bin/sleep), so the gateway-init

Closes#412.
The supervise MCP server blocked the agent's tool call polling for the
operator's decision, and on timeout returned `status: pending` with no
proposal id and no way to poll a specific proposal — so the only way to
learn a late decision was to re-propose (a duplicate).
- `handle_tools_call` pending timeout now returns the `proposal_id` and
points the agent at `check-proposal`.
- New `check-proposal` MCP tool: non-blocking status lookup by proposal id
(pending | approved | modified | rejected | unknown). Reuses the queue's
FileNotFoundError semantics; archives a decided proposal exactly like the
synchronous path, so a pending proposal stays visible to the operator
until it's both decided and polled.
- `TOOL_CHECK_PROPOSAL` constant, re-exported from supervise; kept out of
TOOLS since it never becomes a Proposal.tool.
Enforcement is unchanged — the tools only propose policy; the egress proxy
and git-gate still enforce — so returning early opens no hole. Follow-ups
(git-gate reject-requeue, backpressure, notifications, web console) are in
the PRD.

The pre-receive hook scanned existing-branch updates with the delta range
$old..$new. On a rebase / non-fast-forward force-push onto an advanced main,
$old is no longer an ancestor of $new, so $old..$new expands to all of main's
new history — including the deliberate sandbox-escape gitleaks fixtures — and
the push is rejected on commits that belong to main, not the branch.
Unify the range on `$new --not --all` for every non-delete push (this is the
deferred open question from PRD 0028, which already applied it to new refs
for #106). It scans only the commits the push introduces and is
security-equivalent: the bare repo's refs come only from trusted upstream
mirror-fetch and gitleaks-gated pushes, so an excluded commit is
already-upstream or already-scanned. It is also more correct for
non-fast-forward pushes, where $old..$new can skip commits off the direct path.

`backend setup/status/teardown` manage host prerequisites only and never
open the store, but the CLI dispatcher ran the schema-migration gate before
every command. On a non-TTY runner the gate's `Migrate now? [y/N]` prompt
reads EOF and refuses, so `backend status --backend=firecracker` exits 1 —
breaking the Firecracker CI preflight on any host without a pre-migrated DB.
Exempt `backend` from the gate; store-touching commands stay gated.

- Rename _BACKENDS → _backends: pyright treats uppercase module-level
names as constants and flags the reassignment in _get_backends() as
reportConstantRedefinition; lowercase avoids this.
- Add TYPE_CHECKING guard importing CommitCancelled/Freezer/get_freezer
from .freeze: pyright cannot see module-level __getattr__ bindings, so
reportUnsupportedDunderAll fired for those three __all__ entries; the
guard makes them visible to the type checker without running at import
time.
- Update test_backend_selection.py to patch _backends (lowercase).
Importing backend.docker.util previously triggered eager loading of all
three backend packages (~76 modules) because backend/__init__.py imported
DockerBottleBackend, FirecrackerBottleBackend, and MacosContainerBottleBackend
at module scope. This made the module prohibitively expensive to import
from the orchestrator layer and elsewhere.
The three backend imports are now deferred into _get_backends(), which
loads all three on first call and caches the result in the module-level
_BACKENDS variable (initially None). Module-level __getattr__ exposes
backend classes and freeze symbols lazily for existing import/patch sites.
backend/docker/util.py raw subprocess.run(["docker", ...]) calls are
replaced with the shared run_docker primitive from docker_cmd, eliminating
the duplication between the backend and orchestrator implementations.
_silent_run() is removed; image_exists() is inlined directly onto
run_docker. The commit_container test is updated to patch run_docker
instead of subprocess.run.
Install bot_bottle via pip in Dockerfile.gateway instead of COPYing
individual .py files flat under /app/. This eliminates the try/except
import shims in egress_addon_core, dlp_detectors, egress_addon,
supervise, supervise_server, and git_http_backend that existed only
to support the flat-bundle layout.
Adds bot_bottle/constants.py as a single source of truth for
IDENTITY_HEADER and GIT_GATE_TIMEOUT_SECS, removing the duplicated
literal definitions in egress_addon.py, supervise_server.py,
git_http_backend.py, and git_gate_render.py.
Test files updated to match: test_supervise_server.py drops the
sys.path.insert hack in favour of direct package imports; the
egress_addon test shims no longer pre-populate sys.modules with a
bare egress_addon_core alias.
b1850be's fail-closed-503 test (rebased in from main) built a git-http
server with a flat repo.git and no policy_resolver. The resolver-only
data plane on this branch denies an unattributed request with 404 before
it reaches the access-hook path the test exercises, so it saw 404 != 503.
Nest the bare repo under <root>/<_BID>/ and set _FixedResolver(_BID) on
the server, matching every other test in this module, so the request is
attributed and reaches the access-hook (mocked to raise PermissionError)
that the 503 fail-closed behavior guards.

Follow-ups from the #402 review of the single-tenant data-plane teardown.
- egress_entrypoint.sh: refuse to launch mitmdump when
BOT_BOTTLE_ORCHESTRATOR_URL is unset, so the fail-closed guarantee no
longer rests solely on mitmproxy's errorcheck addon exiting on the
addon's load-time raise. A misconfigured gateway can never come up as
a bare TLS-bumping open proxy with no policy.
- orchestrator/gateway.py: ensure_running() raises GatewayError on an
empty orchestrator URL — a URL-less launch would only crash-loop the
now-resolver-only daemons (egress raises, git-http exits 1, supervise
exits 2). The env-injection branch is now unconditional.
- Drop stale "single-tenant" / "reads routes.yaml" comments in
gateway.py and egress_entrypoint.sh, and the /etc/egress/routes.yaml
layout line in Dockerfile.gateway.
- Tests: gateway fixtures supply an orchestrator URL; add a
refuse-without-URL test and assert the URL env is injected.

All three backends (docker, firecracker, macos-container) now launch through
the consolidated orchestrator, and every production gateway sets
BOT_BOTTLE_ORCHESTRATOR_URL — so the legacy single-tenant (`resolver is None`)
branches in the shared gateway's data plane were unreachable dead code, a second
security-relevant path to keep correct in parallel with the live one. Make the
orchestrator resolver mandatory and delete the single-tenant paths from the
three data-plane modules.
egress_addon.py: drop the static routes file entirely — EGRESS_ROUTES, _reload,
the SIGHUP handler, self.config, and the SUPERVISE_BOTTLE_SLUG env slug. The
per-request /resolve is the only policy source; __init__ fail-closes if
BOT_BOTTLE_ORCHESTRATOR_URL is unset. Introspection (`_egress.local/allowlist`)
now reports the calling bottle's *resolved* routes. The block/redact log gates
and _req_ctx redaction now read the per-flow config/env from the request-time
stash, so they use each bottle's log level and token set (they silently used the
empty static config before). Nothing sends `docker kill --signal HUP` to the
gateway in the consolidated model (the egress applicators fail closed), so
removing the SIGHUP reload is safe.
git_http_backend.py: resolver mandatory; no flat-root fallback. main() refuses
to start without an orchestrator URL; a request whose source resolves to no
bottle 404s.
supervise_server.py: resolver mandatory; every proposal is attributed to the
source-IP-resolved bottle. Remove handle_list_egress_routes (the proxy-fetch
introspection that only worked when the proxy carried one bottle's identity) —
list-egress-routes is answered from the resolved policy. main() refuses to start
without an orchestrator URL.
Tests: a host-side fake resolver serves each test's Config through the real
parse path (a small YAML-subset emitter round-trips route_to_yaml_dict); the
response/websocket hooks stash it as request() would. Deletes the tests for the
removed static-config, SIGHUP-reload, and single-tenant-passthrough paths; adds
fail-closed-without-orchestrator coverage.
Follow-up: gateway_init still forwards SIGHUP to the egress child (now dormant —
no one sends it); the README still describes the docker backend's per-bottle
topology. Both are outside the data-plane teardown.

Cloning/fetching from the git-gate on the Apple-container backend failed with
"empty reply from server" (curl exit 52). Root cause: the git-http handler
crashed on every upload-pack with
PermissionError: [Errno 13] Permission denied: '/etc/git-gate/access-hook'
The access-hook is exec'd directly, so it needs the x bit. prepare() stages it
0o700 and trusted the gateway copy to carry that mode. `docker cp` does; the
Apple `container cp` (AppleGatewayTransport) does not, landing the hook 0o644 →
EACCES. The unhandled exception killed the handler thread, closing the socket
with no HTTP response — which the client sees as the opaque empty reply.
- provision_git_gate now `chmod +x`es the access-hook on the gateway side after
the copy, so it's executable under every transport (docker/apple/firecracker).
- git-http handler wraps the access-hook subprocess.run: an OSError /
SubprocessError (un-execable, timed out) now fails closed with a 503 instead
of crashing the thread into an empty reply — a gate that can't run its hook
should deny, visibly.
- Updates the now-misleading "docker cp preserves source mode" comment in
git_gate.prepare().
Regression tests: provisioning applies +x to the access-hook; the handler
returns 503 (not an empty reply) when the hook can't be exec'd.

Self-review of this PR: making `response()` run in the consolidated gateway
also activates its `LOG_FULL` `_log_response` call there — previously
unreachable, since the empty static config made `response()` return early. That
logger redacted with `os.environ`, which in multi-tenant mode does NOT hold the
bottle's per-request `/resolve` tokens (only the resolved `env` overlay does),
so a non-token-shaped provisioned secret appearing in a response could be logged
in the clear.
Thread the resolved per-flow `env` into `_log_request` / `_log_response` so the
LOG_FULL redaction scrubs the calling bottle's secrets. Adds a regression test
(a non-token-shaped `/resolve` secret, absent from os.environ, must not appear
in the response log) and updates the redaction-test helpers for the new arg.

In the consolidated (multi-tenant) gateway the addon's static `self.config`
is empty — each request's real policy comes from the per-request `/resolve`.
`response()` and `websocket_message()` still matched routes against that empty
config, so inbound prompt-injection DLP and WebSocket credential/injection DLP
silently skipped every scan (fail-open) whenever the gateway ran multi-tenant.
This is backend-agnostic: the gateway image (and this addon) is shared by the
Firecracker, macOS, and docker consolidated backends.
Resolve the per-flow (config, slug, env) once in `request()`, stash it on
`flow.metadata`, and have both hooks read it back — falling back to the static
single-tenant values for a flow that never passed through `request()`. Reusing
the request's one `/resolve` avoids a round-trip per response and per WebSocket
frame.
Adds multi-tenant regression tests for both hooks that fail against the old
fall-open behaviour.

Addresses the 5 lower-priority findings left as follow-up in the earlier
review, now that each has a concrete answer:
- Add gateway_name: str = GATEWAY_NAME to OrchestratorService.__init__
(mirrors the existing orchestrator_name param) and thread it through
_gateway(). Deletes the test's _IsolatedOrchestratorService subclass,
which existed only to override a private method for this one kwarg —
any caller needing gateway-name isolation can now use the public
constructor. Backward compatible: every existing caller constructs
OrchestratorService with keyword args and a sensible default is kept.
- Give the test its own fixed image tags (bot-bottle-orchestrator:itest,
bot-bottle-gateway:itest) instead of the production :latest ones.
_running_image_is_current() keys gateway staleness off the image tag's
ID, not per-instance identity, so rebuilding the shared :latest tag from
whatever's on disk during a test run could make a real host's running
production gateway look stale and get force-recreated. Fixed tags (not
per-run-suffixed, so they don't accumulate) fully decouple the two.
- setUp -> setUpClass/tearDownClass: all 5 tests are read-only checks
against the same running control plane, so one shared container
lifecycle replaces 5 (each of which paid its own container-start +
image-build + health-poll cycle). Cuts the file's wall-clock roughly
4x (11.5s -> 2.9-4.3s) and, combined with the network-rm cleanup from
the previous commit, means one cleanup instead of five.
- Reuse OrchestratorClient (bot_bottle/orchestrator/client.py) instead of
a hand-rolled urllib helper — the test now exercises the same
request/response code path the real host CLI uses, rather than a
private copy that could silently drift from it.
- Add the chown workaround test_multitenant_isolation.py already needed
for this exact bind-mount: the orchestrator container has no USER
directive, so it writes the registry DB as root into the throwaway
host_root; chown it back before tempdir cleanup so that doesn't raise
PermissionError on native Linux Docker (no UID remap, unlike Docker
Desktop's macOS VM).
Verified: ran the suite twice in a row (idempotency — fixed image tags
don't accumulate, 5/5 pass both times, 2.99-4.33s each), the real
~/.bot-bottle/control-plane-token is untouched, zero leaked networks or
containers after either run, exactly 2 :itest images (not growing), the
full orchestrator unit suite (93 tests) and the sibling docker
gateway/broker integration tests still pass. pyright clean, pylint
10.00/10 on both changed files.

Pushing the previous two fixes surfaced a real, currently-failing CI run
(gitea actions run 2164, jobs "integration" and "coverage"): every one of
the 5 new tests errored in setUp with
docker: Error response from daemon: error while creating mount source
path '/workspace/didericis/bot-bottle': mkdir /workspace: read-only
file system
This is finding #4 from the review of the previous commit, now confirmed
live rather than just plausible: act_runner's job-container topology
can't satisfy the orchestrator's host-path bind mount, the same
constraint test_multitenant_isolation.py, test_gateway_image.py, and
test_sandbox_escape.py already skip around. Add the identical
skip_unless_docker + GITEA_ACTIONS guard so this test degrades the same
way its siblings do instead of failing the job.

Two bugs surfaced by a review of the previous commit:
- host_control_plane_token() resolves its path via the ambient
BOT_BOTTLE_ROOT env var, not the host_root kwarg passed to
OrchestratorService (that kwarg only controls the DB bind-mount
destination). The test's isolation claim was false as a result: running
it read/wrote the developer's real ~/.bot-bottle/control-plane-token
instead of the throwaway temp dir — confirmed directly on disk. Fixed
by pointing the env var at the same temp dir for the test's duration
and restoring it via addCleanup.
- ensure_running() creates a per-bottle Docker network but stop() only
ever removes containers, never the network — every run of this test
leaked one bridge network permanently (found and removed 5 from prior
runs via `docker network ls`). Fixed with an explicit `docker network
rm` in addCleanup.
Verified: re-ran the suite twice: 5/5 pass both times, the real
~/.bot-bottle/control-plane-token timestamp is unchanged across both runs
(proving isolation), and `docker network ls` shows zero leaked
bot-bottle-net-itest-* networks afterward. pyright clean, pylint 10.00/10.
Remaining findings from the same review (missing GITEA_ACTIONS skip
guard, root-owned bind-mount cleanup on native Linux, no setUpClass,
reinvented OrchestratorClient, gateway_name should be a constructor
param rather than a subclassed private-method override) are left for a
follow-up — each is a real, separate design/scope call, not a
mechanical fix like these two.

ca91fc4 fixed the control plane's missing caller authentication but only
verified it end-to-end on Apple Container; Docker had the same code change
(docker_cmd.py's env injection) backed only by the in-process dispatch()
unit tests, which never exercise the real HTTP server or a real container.
Ran it for real first: brought up the actual orchestrator + gateway via
Docker, hit the published control-plane port directly. Confirms /health
stays open, /bottles and /resolve both 401 with no token or a wrong one
(the enumeration and credential-lift vectors from #400), and /bottles
succeeds with the real per-host secret.
Added as a proper integration test so this stays covered: a subclass of
OrchestratorService giving the gateway its own unique name too (the base
class only parameterizes the orchestrator's), plus a throwaway
BOT_BOTTLE_ROOT and a random port, so a run can never collide with a real
host's orchestrator or gateway. Gated on a reachable Docker daemon, same
as the existing docker gateway/broker integration tests.

The control plane had no caller authentication — dispatch() routed every
request straight through, and the only guards anywhere were the
(source_ip, identity_token) checks inside /resolve and /attribute, which
authenticate the *bottle* a request is about, not the *caller*. On the
consolidated backends the agent shares a network with the control-plane port
(macOS: the infra container runs 8099 on the agent's --internal network;
docker: the orchestrator container sits on the shared gateway network), so a
prompt-injected agent could GET /bottles (enumerate siblings + policies),
PUT /bottles/<id>/policy (rewrite its own egress allowlist to allow-all),
POST /resolve (read the injected upstream credentials it's never meant to
see), and POST /supervise/respond (self-approve its own proposals). Every
README guarantee collapsed to the agent's discretion.
Fix: a per-host control-plane secret required on every route but GET /health,
compared with hmac.compare_digest. It is held only by the trusted callers and
never handed to an agent:
- minted + persisted 0600 at <root>/control-plane-token (paths.host_control_plane_token);
- injected as $BOT_BOTTLE_CONTROL_PLANE_TOKEN into the orchestrator + gateway
containers via bare `--env NAME` (value inherited from the launch process,
so it never lands on argv or in `container/docker inspect`);
- presented by the gateway's PolicyResolver (reads the env) on /resolve, and by
the host CLI's OrchestratorClient (reads the host file) on every call.
The agent container is never given the env var or the host file, so from a
bottle every /bottles*, /resolve, /attribute, and /supervise/* call now
returns 401 — closing the enumeration, allowlist-rewrite, credential-lift, and
self-approval. The existing (source_ip, identity_token) checks stay as
defense-in-depth.
Enforced when configured: macOS + docker inject the secret (→ enforced). With
no secret set the server runs open and warns loudly at startup — a
fail-visible fallback for the unit suite and for Firecracker, whose
port-scoped nft already blocks agents from 8099 (wiring the secret into its
infra-VM init is a clean fast-follow, left out here to avoid churning the
prebuilt-artifact hash).
Verified end-to-end on real Apple Container: infra comes up healthy, the host
CLI (with the secret) lists bottles while an unauthenticated GET /bottles gets
401, all five issue-#400 attacks from inside the agent get 401, and egress
policy still works (200 allowed / 403 denied) — proving the gateway
authenticates to /resolve with the secret. 1829 unit tests pass, pyright
clean, pylint 9.91.
Refs #400.

Adopts the firecracker infra-VM pattern for macOS: the orchestrator control
plane and the gateway data plane now run in a SINGLE Apple container instead of
two. Apple Containers are lightweight VMs with separate kernels, so the prior
two-container design had both guests writing one bot-bottle.db over virtiofs,
where fcntl locks are not coherent across kernels — concurrent writes (the
orchestrator's registry vs the gateway supervise daemon's queue) could corrupt
it. One container = one kernel = coherent locking.
The DB moves onto a container-only Apple volume (bot-bottle-mac-db), never
bind-mounted from the host, so no host process opens the live file either. The
host CLI already reaches registry + supervise state over the control-plane HTTP
surface (cli/supervise.py uses OrchestratorClient), exactly as firecracker's
VM-only DB requires.
Two simplifications fall out of the single container:
- No DNS dance: the control plane and gateway daemons reach each other over
127.0.0.1, so the orchestrator-before-gateway ordering (a workaround for
Apple having no container DNS) is gone, along with the moved-IP recreate
logic it needed.
- Net -243 lines.
Mechanics: the infra container runs from the gateway image with the
control-plane source bind-mounted read-only (like the docker orchestrator, so a
code change needs no rebuild) and a small sh -c init that starts both processes
(mirrors firecracker's _infra_init). Also implements the macOS backend's
ensure_orchestrator() and adds it to discover_orchestrator_url, so operator
tools (supervise) can bring up / find the control plane on demand — previously
the macOS backend died with "no orchestrator control plane".
Verified end-to-end on real Apple Container 1.0.0: the single infra container
comes up healthy (one address for control plane + gateway), both processes run,
the DB is written on the container-only volume, host-side supervise works over
HTTP, and a registered agent gets 200 for an allowed host / 403 for a denied
one. 1824 unit tests pass with `container` absent (CI parity), pyright clean,
pylint 9.89.

Addresses findings from a high-effort review of the PRD 0070 macOS backend.
Correctness:
- Stamp identity_token onto MacosContainerBottlePlan after registration. git's
gitconfig extraHeader and the supervise MCP --header read
getattr(plan,"identity_token","") at provision time, and both reach the
gateway on NO_PROXY (bypassing the egress proxy that carries the token). The
plan never carried it, so /resolve fail-closed and every git fetch/push and
supervise call from a macOS bottle would have been denied. Registration
precedes provision(), so — unlike the run-time env — the plan can carry it.
- Self-heal the orchestrator: recreate when it is not (source-current AND
answering /health), not on the source-hash label alone. A container running
current code but with a wedged HTTP server was left alone and polled to
death, failing every launch until manual deletion.
- image_digest and container_image_digest now read the same descriptor.digest
field; dropped image_digest's id/tag fallback that could yield a value the
container side can't produce — a permanent mismatch would have recreated the
shared gateway on every launch (severing every live bottle's egress, since
the replacement gets a new DHCP address).
- Poll for the agent's and gateway's DHCP address instead of a fatal read
right after `container run` (there is no --ip; the address can lag start).
Cleanup:
- One _inspect_first + _descriptor_digest behind the four inspect readers.
- Shared bind_mount_spec (util) and host_db_dir (paths) replace per-module
copies; _GIT_HTTP_PORT now imports git_http_backend.DEFAULT_PORT.
- Drop the dead _url cache / url property and the write-only agent_proxy_url.
Deferred (noted on the PR, not fixed here): the gateway image rebuilding on
every launch (needs source-hash-labeled build), SQLite shared across VM
guests, and the sh -lc profile-override edge — each is design-level or
behavior-risk beyond a review fix.
Verified: real Apple Container bring-up is green and idempotent; 1826 unit
tests pass with `container` absent (CI parity), pyright clean, pylint 9.86.

CI's unit + coverage jobs failed with `FileNotFoundError: 'container'`: three
tests reached the real Apple CLI, which exists on a macOS dev host but not on
the Linux runner. They passed locally for that reason alone — and two of them
were quietly creating real Apple networks on the dev host as a side effect.
- `test_enumerate_active_is_empty_while_disabled` asserted the disabled-era
stub and called `enumerate_active()` unmocked. The backend launches bottles
again, so it now covers the real enumeration: slug parsing, exclusion of the
shared gateway/orchestrator singletons, and the CLI-failure path.
- The two orchestrator tests patched `orchestrator_service.container_mod`, but
`_run_orchestrator_container` reaches the CLI through `ensure_networks`,
which is imported from the gateway module and resolves `container_mod` in
*its* namespace. Patch the imported name instead.
Adds a test that the networks exist before the orchestrator runs — the
ordering the escaped call was hiding.
Verified by reproducing the CI environment locally (`PATH` without the
`container` binary): 3 failures before, 1818 passing after.

Re-enables the macos-container backend on the shared per-host orchestrator +
gateway, replacing the per-bottle companion container removed in #385. This is
the last backend in PRD 0070's roadmap.
Apple Container 1.0.0 forced three departures from the docker shape, each
verified against the live CLI (findings recorded in the networking spike):
- No `--ip`. The address is DHCP-assigned and knowable only once the container
runs, so the order inverts: gateway up -> run agent -> read its address ->
register. The identity token is minted by registration and therefore cannot
be in the agent's run-time env; it rides the proxy URL applied at
`container exec` time (bare `--env` names keep it off argv).
- No container DNS. The gateway can only be handed the control plane's IP, so
the orchestrator starts first and the gateway is pointed at its address.
- No `network connect`. Networks are fixed at run time, so the shared host-only
network is created up front; per-bottle networks would restart the gateway
on every launch and defeat the consolidation.
The agent runs with `--cap-drop CAP_NET_RAW`: Apple grants NET_RAW by default,
which would let an agent forge a neighbour's source address on the shared
segment. NET_ADMIN is already absent, so this closes the source-address half of
PRD 0070's attribution invariant.
Verified end-to-end on real Apple Container 1.0.0: both images build, the
control plane comes up healthy, the gateway reaches it by IP, and a registered
agent gets 200 for a host in its routes and 403 for one outside them. Bring-up
is idempotent — a second launch does not churn the singletons.

Follow-up to the codex review on #398. os.open's mode arg only applies on
creation, so a committed-rootfs.tar.partial left 0644 by an interrupted run
would be opened/truncated (not re-moded) and stay world-readable for the
whole SSH stream. Unlink any leftover and exclusively recreate it
(O_EXCL|O_NOFOLLOW), then fchmod 0600 immediately so umask can't loosen it.
Test pre-creates a 0644 partial and asserts the fd is 0600 mid-stream.

Address the codex review on #398:
- P1: inject_guest_boot no longer follows a symlink at bb-init/bb-dropbear.
A committed snapshot is guest-controlled and could plant those paths as
symlinks aimed at a host file (e.g. bb-init -> ~/.bashrc); write_text /
copy2 would then overwrite the target as the host user during resume.
Replace any pre-existing entry and create the files with
O_EXCL|O_NOFOLLOW so the write stays inside the staging tree.
- P2: write the snapshot tar owner-only (0600). It can contain the bottle's
private workspace; it was being created world-readable (0644).
