fix(security): authenticate the orchestrator control plane (issue #400 Critical)

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.

+"""Consolidated bottle launch sequence for the macOS backend (PRD 0070).
+
+The docker backend allocates a free address, pins the agent to it with
+`--ip`, registers it, *then* starts the agent — registration precedes launch
+because the pinned address is known up front.
+
+**Apple Container 1.0.0 has no `--ip`.** The `--network` flag takes only
+`<name>[,mac=…][,mtu=…]`; the address is assigned by vmnet's DHCP and is
+knowable only once the container is running. So the macOS order inverts:
+
+    ensure_gateway()  ->  caller starts the agent  ->  register_agent(source_ip)
+
+That is why this module exposes two functions where docker has one — the
+caller has to start the agent in between. `ensure_gateway` runs first because
+the agent's proxy env needs the gateway's address at `container run` time; the
+agent's *own* address (the attribution key) only exists afterwards.
+
+The control plane and the gateway are one **infra container** here (see
+`infra`), so `gateway_ip` and the control-plane host are the same address.
+
+The consequence for the identity token: it is minted by registration, i.e.
+*after* the agent container exists, so it cannot be baked into the run-time
+env the way docker's compose spec does. It is delivered at `container exec`
+time instead — see `bottle.MacosContainerBottle`.
+
+That delivery is load-bearing, not a nicety: `/resolve` requires a matching
+`(source_ip, identity_token)` pair and fail-closes with no source-IP-only
+fallback (#366). So egress that does not carry the token is denied — which is
+the safe direction, and is why the agent's init process is a bare `sleep` and
+every real command arrives through `container exec`.

+"""The per-host infra container for the macOS backend (PRD 0070).
+
+A single persistent Apple container that runs BOTH the orchestrator control
+plane and the gateway data plane — the macOS analogue of the Firecracker infra
+VM (`backend/firecracker/infra_vm.py`), not the docker backend's two separate
+containers.
+
+Why one container, not two: Apple Containers are lightweight VMs, each with its
+own kernel. The docker backend runs the orchestrator and gateway as two
+containers safely because they share the host kernel, so their concurrent
+writes to the one `bot-bottle.db` (the orchestrator's registry + the gateway
+supervise daemon's queue) are serialized by coherent `fcntl` locks. Across two
+*guest* kernels sharing a virtiofs-mounted DB those locks are not coherent, and
+concurrent writers can corrupt the file. Firecracker solved this by putting
+both services in one guest with the DB on a device only that guest mounts; this
+does the same with Apple primitives.
+
+Two consequences fall out of the single container, both simplifications:
+
+- **No DNS dance.** The control plane and the gateway daemons reach each other
+  over `127.0.0.1`, so nothing depends on Apple's (absent) container DNS and
+  there is no orchestrator-before-gateway ordering to get right.
+- **The DB is never host-shared.** It lives on a container-only volume, so no
+  host process opens the live file. The host CLI reaches registry + supervise
+  state through the control-plane HTTP surface (`cli/supervise.py` already uses
+  `OrchestratorClient`), exactly as it does for firecracker.
+
+The control-plane source is bind-mounted (like the docker orchestrator), so a
+code change takes effect on the next launch without an image rebuild; the
+gateway daemons are baked in the gateway image and rebuild through its own
+digest check.

-"""Launch flow for the macOS Apple Container backend — disabled (#385).
+"""Launch flow for the macOS Apple Container backend (PRD 0070).
 
-This backend launched a per-bottle companion container (the egress /
-git-gate / supervise data plane) alongside the agent container, with the
-agent's proxy env pointed at the companion's host-only IP. That
-per-bottle-companion architecture was removed in the companion-container removal;
-the macOS backend will be re-enabled once it grows the consolidated
-per-host gateway the docker backend already uses.
+The agent container attaches to the **shared host-only gateway network** and
+proxies egress through the one per-host gateway, replacing the per-bottle
+companion container removed in #385.
 
-Until then, launching a macOS bottle fails closed. `prepare` / `status`
-/ cleanup still work.
+The order differs from docker's, forced by Apple Container 1.0.0 having no
+`--ip` (see `consolidated_launch`): the agent is started *before* it is
+registered, because its DHCP-assigned address — the attribution key — does not
+exist until then.
+
+    gateway up -> run agent -> read its IP -> register it -> provision
+
+Two things follow from that inversion:
+
+- The **identity token** is minted by registration and so cannot be in the
+  agent's run-time env; it rides the proxy URL applied at `container exec`
+  time (`bottle.MacosContainerBottle`). `/resolve` requires it (#366), so
+  egress without it is denied — hence the bare `sleep` init: every real agent
+  command goes through exec and therefore carries the token.
+- The agent is run with `--cap-drop CAP_NET_RAW`. Apple Container grants
+  NET_RAW by default, which would let an agent open a raw socket and forge a
+  neighbour's source address on the shared segment. NET_ADMIN is already
+  absent (the agent cannot change its own address or route), so dropping
+  NET_RAW is what closes the source-address half of PRD 0070's invariant:
+  "a packet's source address, as seen by the orchestrator, provably identifies
+  the originating bottle." The identity token is the other half — an attacker
+  would need to forge the address *and* steal the token — but the invariant is
+  a stated precondition of consolidation, so it is enforced on its own terms
+  rather than left to the token.

docs/research/apple-container-networking-spike.md

@@ -358,3 +358,111 @@ the Apple Container-specific constraints directly:
 
 Do not implement the backend as a direct clone of Docker Compose
 service aliases. That assumption failed in this run.
+
+## Addendum: consolidated-gateway findings (2026-07-17, PRD 0070)
+
+Re-tested on Apple Container 1.0.0 while porting the backend to the
+per-host consolidated gateway (#351). The two-network shape above still
+holds; these are the additional constraints that shaped the port, each
+verified against the live CLI on this host.
+
+### No static IP for a container
+
+`container run --network` accepts only
+`<name>[,mac=XX:XX:XX:XX:XX:XX][,mtu=VALUE]`. There is no `--ip`. The
+address comes from vmnet's DHCP and is knowable only after the container
+is running:
+
+```console
+$ container run --name a --network bb-net --detach alpine sleep 900
+$ container inspect a | jq -r '.[0].status.networks[0].ipv4Address'
+192.168.128.3/24
+```
+
+Consequence: the docker backend's "allocate a free IP -> pin it with
+`--ip` -> register -> launch" order cannot be reproduced. macOS inverts
+it to "launch -> read the assigned address -> register". The identity
+token therefore cannot be in the agent's run-time env (registration mints
+it after the container exists) and is delivered at `container exec` time.
+
+### Networks are fixed at run time
+
+There is no `container network connect`; `container network` exposes only
+`create`, `delete`, `list`, `inspect`, `prune`. A network cannot be
+attached to a running container, so a *persistent* shared gateway rules
+out per-bottle networks — they would force a gateway restart per launch.
+One shared host-only network, created up front, is the only shape that
+keeps the gateway a singleton.
+
+### No container DNS
+
+Containers cannot resolve each other by name; the host-only network's
+resolver refuses the query:
+
+```console
+$ container exec agent nslookup gw
+;; connection timed out; no servers could be reached
+$ container exec agent cat /etc/resolv.conf
+nameserver 192.168.128.1
+```
+
+Consequence: the gateway is handed the control plane's **IP**, not a
+container name as on docker. That forces the startup order
+orchestrator -> read its address -> gateway.
+
+### The host can reach the host-only network directly
+
+```console
+$ container inspect c | jq -r '.[0].status.networks[0].ipv4Address'
+192.168.128.2/24
+$ curl -s http://192.168.128.2:8099/i
+ok
+```
+
+So no `--publish` hop is needed: the host CLI and the gateway use the
+same control-plane URL. Docker needs `--publish 127.0.0.1:...` plus a
+separate internal URL for the same job.
+
+### CAP_NET_RAW is granted by default — and matters for attribution
+
+Apple grants NET_RAW but not NET_ADMIN. The agent therefore cannot change
+its own address or route:
+
+```console
+$ container exec agent ip addr add 192.168.128.99/24 dev eth0
+ip: RTNETLINK answers: Operation not permitted
+$ container exec agent ip route replace default via 192.168.128.2 dev eth0
+ip: RTNETLINK answers: Operation not permitted
+$ container exec agent grep CapEff /proc/self/status
+CapEff:	00000000a80425fb        # bit 13 (NET_RAW) set, bit 12 (NET_ADMIN) clear
+```
+
+But NET_RAW permits raw sockets, i.e. source-address forgery against
+neighbours on the shared segment — directly against PRD 0070's invariant
+("a packet's source address, as seen by the orchestrator, provably
+identifies the originating bottle"). `--cap-drop CAP_NET_RAW` closes it:
+
+```console
+$ container run --cap-drop CAP_NET_RAW ... alpine
+$ container exec nr grep CapEff /proc/self/status
+CapEff:	00000000a80405fb        # bit 13 cleared
+$ container exec nr ping -c1 192.168.128.2
+ping: permission denied (are you root?)
+```
+
+The agent is run with `--cap-drop CAP_NET_RAW` for this reason.
+
+### `container exec` inherits run-time env, and `--env` overrides it
+
+```console
+$ container run --name e --env FOO=from_run --detach alpine sleep 120
+$ container exec e sh -c 'echo $FOO'
+from_run
+$ container exec --env FOO=from_exec e sh -c 'echo $FOO'
+from_exec
+```
+
+This is what makes exec-time identity-token delivery work: the token-less
+proxy URL baked in at launch is superseded by the token-bearing one at
+exec. Bare `--env NAME` (inherit from the parent process) keeps the token
+value off argv.
