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.

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.

The `bot-bottle supervise` operator TUI read and wrote the queue DB
directly and tried a backend-specific live "apply" (which was unwired —
it raised). It now talks only to the orchestrator control plane:
- OrchestratorClient gains supervise_pending() + supervise_respond().
- discover_orchestrator_url() finds the one running per-host control
plane by health-probing the backends' well-known :8099 addresses
(docker publishes on loopback; the firecracker infra VM serves it on
the orchestrator TAP) — no backend branching in the TUI.
- discover_pending/approve/reject call the client; the server does the
apply + response + audit atomically. The dead direct-DB apply/audit
helpers and the docker/macos applicator imports are gone.
- A missing control plane is now a clean one-line error up front, not a
mid-curses crash.
CLI tests move to mocking the client (the DB-write behaviour they used to
assert is now server-side, covered by test_orchestrator_service). Docker's
orchestrator-container DB wiring lands next so its /supervise endpoints hit
the same shared DB.

The cut-over dropped the per-bottle token flow, so an authed egress route on
the shared gateway failed with 'env var EGRESS_TOKEN_0 is unset' — the gateway
reads the token from its env, but a shared gateway has no per-bottle env.
Now the bottle's egress auth tokens travel to the gateway over /resolve and
the addon injects from them, mirroring what the per-bottle sidecar's env did:
- launch resolves the token values from the host env and hands them to the
orchestrator, which holds them IN MEMORY (keyed by bottle_id, never written
to the registry DB) and serves them on /resolve;
- PolicyResolver.resolve_policy_and_bottle_id + resolve_client_context now
return the token map alongside policy + bottle_id (one round-trip);
- the egress addon overlays the process env with the bottle's tokens per
request and uses that env for auth injection AND DLP — the agent never sees
the credential.
Secrets stay off disk (validated: /resolve returns the token, the registry DB
does not contain it). SecretProvider (#355) is the future hardening.

The launch path's counterpart to the gateway-side PolicyResolver: a trusted
host-side HTTP client for the orchestrator control plane, so the CLI can
register/teardown/re-policy bottles. Stdlib-only.
- OrchestratorClient.register_bottle(source_ip, *, image_ref, metadata,
policy) -> RegisteredBottle(bottle_id, identity_token) (POST /bottles)
- teardown_bottle(id) -> bool (DELETE; 404 -> False, idempotent for cleanup)
- set_policy(id, policy) -> bool (PUT; live reload)
- list_bottles() / health()
- Unlike the fail-closed data-plane resolver, this is the trusted caller: a
non-2xx (other than the meaningful 404s) raises OrchestratorClientError so
the launch path surfaces failures rather than swallowing them.
pyright 0 errors; pylint 9.82/10; unit suite green (1742 tests; the 13
test_sidecar_init /bin/sleep errors are pre-existing NixOS-local noise).
