refactor(macos): one infra container (control plane + gateway), fixes shared-DB races

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.

-On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a sidecar bundle attached to both that internal network and a NAT egress network. The agent gets HTTP(S)_PROXY and CA bundle env vars pointing at the sidecar's internal-network IP, so HTTP/HTTPS traffic flows through the sidecar instead of direct egress. `bottle.git` / git-gate is intentionally deferred on this backend until a safe Apple Container key-delivery path exists.

+Agent Dockerfiles build **inside the persistent per-host infra VM**

+daemon, no root-equivalent `docker` group. The build runs over SSH against the
+infra VM and its rootfs streams back to the host, where the existing

+one buildah image (`bot-bottle-infra`) and no contention for the orchestrator
+TAP. Tradeoff: an untrusted Dockerfile's `RUN` steps share the VM with the
+control plane + gateway (buildah `--isolation chroot` isn't a hard boundary) —
+the accepted single-VM blast-radius tradeoff, re-splittable into a disposable

+"""Prebuilt infra-VM rootfs, pulled as an artifact (PRD 0069 Stage 2).
+
+The Firecracker infra VM boots a fixed rootfs (orchestrator control plane +
+gateway + buildah, control-plane init as PID 1) that does not vary per launch —
+the per-boot bits (authorized_keys, guest IP) ride the kernel cmdline, so one
+rootfs boots on any host. Instead of building that rootfs on the launch host
+with Docker, we build it **off-host** and publish it as a versioned, ready-to-
+boot ext4 (gzip-compressed) to a Gitea **generic package**; the launch host
+downloads + verifies + boots it. No Docker, no image tooling on the launch
+host — just an HTTP fetch and gunzip.
+
+  publish (off-host, see publish_infra.py):
+    docker build -> rootfs dir -> mke2fs -> gzip -> PUT generic package
+  pull (this module, launch host):
+    GET .../rootfs.ext4.gz (+ .sha256) -> verify -> gunzip -> boot
+
+The artifact **version** is a content hash of everything baked into the rootfs
+(the shipped bot_bottle package, the three Dockerfiles, and the init), so a
+launch host always pulls the artifact matching its code and a content change
+can't silently boot a stale rootfs. A checksum mismatch fails closed.
+
+Set `BOT_BOTTLE_INFRA_BUILD=local` to skip the pull and build the rootfs
+locally with Docker (dev iteration on the Dockerfiles) — see `infra_vm`.

+The per-bottle Docker sidecar bundle is gone. The shared gateway handles

+the VMs' traffic to it, and the nft table's `ct status dnat accept` rule
+in the forward chain lets it pass. The VM still sends to `host_tap_ip:PORT`
+— the address its world is, by nft design, limited to.
 
 Isolation is enforced by the operator-provisioned nft table (checked
-fail-closed in preflight): a VM reaches only its sidecar (DNAT'd from
-the host TAP IP) and nothing else. The agent's HTTPS_PROXY therefore
-points at `http://<host_tap_ip>:9099`, its only route to the world.

+"""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 (PRD 0070).
 
-This backend keeps the explicit proxy-env enforcement model for v1:
-the agent container is attached only to a host-only Apple Container
-network, while the sidecar bundle is attached to a NAT network first
-and the host-only network second. The sidecar's host-only IP is
-discovered from `container inspect` and stamped into the agent's
-HTTP_PROXY / HTTPS_PROXY env vars.
+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.
+
+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.

-Before the CLI can register or launch bottles against the consolidated
-model, exactly one orchestrator control plane — and the single per-host
-gateway it manages — must be running. This starts the orchestrator
-dev-harness (`python -m bot_bottle.orchestrator`) as a background host
-process and health-checks it.
+Runs the orchestrator control plane **as a container** on the shared gateway
+network, alongside the gateway container. This is the PRD's "virtualize the
+orchestrator": container↔container between the gateway and the orchestrator
+avoids the host firewall (which drops container→host traffic), and the gateway
+reaches the control plane by container name over docker DNS. The host CLI
+reaches it via a published loopback port.
 
-It is an **idempotent singleton**: `ensure_running` returns immediately if a
-healthy control plane already answers on the port, and otherwise spawns one
-and waits for it to come up. The control-plane port is the singleton key —
-a second orchestrator can't bind it, so a stray double-start fails fast
-rather than forking a rival.
-
-Host-process (not container) on purpose: the PRD sequences the orchestrator
-as a plain-process dev-harness first (fast iteration, and it already has the
-host user's docker access to broker launches), while the data-plane
-*gateway* it manages runs as a container. Wrapping the orchestrator itself
-in a backend-native unit is a later step.
+The orchestrator runs with the **register-only broker** — the *backend*
+launches agent containers (compose), so the orchestrator needs no docker
+socket. That keeps this control-plane container unprivileged; the host manages
+both containers. `ensure_running` is an idempotent singleton (fixed container
+names + the published port).

 Make the Firecracker backend depend on **firecracker + KVM only**, removing
 Docker from the host. Two moves get us there: run the **sidecar bundle as a
 persistent, per-host service** (eventually a Firecracker VM) instead of a
-per-bottle container, and **build agent rootfs images without a host Docker
-daemon** (nix for the fixed images; an in-VM builder for user Dockerfiles).

+registry and unpack them daemonlessly, and build user Dockerfiles in an in-VM

+(CI / a publish step) and pushed to the registry; the launch host only pulls.

-### Stage 2 — Fixed images built with nix (no Docker)
+### Stage 2 — Fixed rootfs prebuilt + pulled as an artifact (no host Docker)
 
-The images bot-bottle *ships* — the sidecar, the agent base, and the builder
-(Stage 3) — are built declaratively with nix (`nixos-generators` /
-`make-ext4-fs` / `pkgs.dockerTools` for the rootfs), producing an ext4 or
-tar with correct ownership. Removes Docker for everything we own and gives
-the rootless-rootfs correctness (#347) for free on these images.
+The one fixed image the Firecracker backend needs at launch — the combined
+**infra** rootfs the infra VM boots (orchestrator control plane + gateway +
+buildah, with the control-plane init as PID 1) — is **prebuilt end-to-end off
+the launch host and published as a versioned, ready-to-boot ext4 artifact**.
+The launch host **downloads the `.ext4` and boots it directly** — no
+`docker build`, no `docker export`, no `mke2fs`, no image tooling at all.
+
+This is possible because the infra rootfs is already **host- and
+bottle-agnostic**: the per-boot bits (authorized_keys, guest IP) arrive on the
+**kernel cmdline**, not in the rootfs (see `build_base_rootfs_dir`). So one
+published ext4 boots on any launch host.
+
+- **Artifact.** `rootfs.ext4` + a `rootfs.ext4.sha256`, published as a Gitea
+  **generic package** (`bot-bottle-firecracker-infra/<tag>`) — generic packages take
+  arbitrary large binaries (no attachment size cap / file-type allowlist that
+  release attachments impose). The matching `vmlinux` kernel can ship the same
+  way, so the whole VM is fetchable.
+- **Pull.** The launch host `GET`s
+  `…/api/packages/<owner>/generic/bot-bottle-firecracker-infra/<tag>/rootfs.ext4` (+
+  `.sha256`) for its pinned tag, verifies the checksum, caches it under the
+  tag, and attaches it as the infra VM's root disk. Host prerequisite is an
+  HTTP client — nothing else. Public packages need no auth to pull; a token
+  with `read:package` covers a private instance.
+- **Registry.** The artifact base URL + owner are configurable, defaulting to
+  this deployment's Gitea (`https://gitea.dideric.is` / `didericis`);
+  overridable via env for other deployments / air-gapped mirrors.
+- **Versioning.** A pinned tag bumped when the infra rootfs contents change
+  (bot_bottle's shipped files, the base deps, or the init), so a launch host
+  pulls the artifact matching its code and a content change can't silently
+  boot a stale rootfs. A checksum mismatch fails closed.
+- **Publish.** A `publish` step (CLI subcommand / CI job) runs the full
+  pipeline **on a build/CI host** — `docker build` the three Dockerfiles →
+  export → inject guest boot → `mke2fs` → upload the `.ext4` + `.sha256`.
+  Building still uses Docker, but never on the launch/runner host, which is
+  the one #348 needs unprivileged.
+- **Dev escape hatch.** An explicit opt-in still builds the rootfs locally
+  with Docker (for iterating on the Dockerfiles without a publish
+  round-trip); it is never the default path.
+
+Removes Docker from the launch host entirely for the fixed image, and the
+launch host needs no OCI/rootfs tooling — just fetch + boot. The build-time
+cache / build-time-egress open problems a from-scratch build would face don't
+arise: the launch host never builds, it downloads a finished disk.

@@ -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.

+- **OneCLI** ([onecli.sh](https://onecli.sh/)) — YC-backed, GA, open-source
+  (Apache-2.0, Rust) "identity gateway for AI agents": a credential/secret
+  broker that holds API keys and OAuth tokens out of the agent's reach and
+  injects them at the network layer (phantom-token — the agent sees a
+  placeholder, the gateway swaps in the real, AES-256-GCM-encrypted credential
+  at request time). Framework-agnostic and drop-in for any HTTP-calling agent,
+  50+ app integrations, plus a hosted cloud tier with a per-agent dashboard and
+  audit logs. Full technical breakdown in
+  [`agent-credential-proxy-landscape.md`](agent-credential-proxy-landscape.md).
+
+  **How close a competitor:** near-exact on the *single axis of agent secret
+  custody* — the exact thing bot-bottle sells as "the agent never sees real
+  credentials, even via `printenv`." OneCLI does that one job well, is mature
+  and funded, and is *more portable* (it sits in front of anything; bot-bottle
+  only helps agents launched through bot-bottle). Takeaway: bot-bottle should
+  stop treating secret custody as a *unique* differentiator. But OneCLI is
+  **not** a competitor to bot-bottle's actual product — it does no agent
+  sandboxing (containers/microVMs), no fleet/manifest layer, no named agents /
+  skills / per-agent system prompts, no multi-provider launching, no egress
+  firewall.
+
+  **Our edge:** (1) *Isolation is the product, not a proxy.* OneCLI keeps the
+  key out of reach at the network layer, but the agent itself still runs
+  unsandboxed — a hijacked agent behind OneCLI has full run of its host and can
+  exfil captured data through any allowed host. bot-bottle runs the agent inside
+  a kernel/VM-enforced sandbox, injects credentials across that same
+  out-of-process boundary, *and* clamps egress with pipelock — defense in depth
+  vs. a single network layer. (2) *Fleet + manifest model* with named agents,
+  skills, per-agent system prompts, multi-provider and multi-backend — OneCLI
+  has no equivalent. (3) *Trust posture:* OneCLI's managed tier reintroduces a
+  third-party credential custodian, whereas bot-bottle's OSS-runtime +
+  paid-control-plane split keeps custody inside the operator's own boundary —
+  the stronger story for the security-minded self-hoster. (4) *Runs inside your
+  network boundary — local/internal reach.* Because bot-bottle executes the
+  agent on your own host (homelab, corporate LAN, a Tailnet) and egress is a
+  manifest field, giving an agent *scoped* access to **internal** resources — a
+  private Gitea, a LAN database, a Tailscale node — is just another egress-route
+  line, not a networking project (the same move an operator already makes to
+  reach their Tailscale services). OneCLI's OSS core can self-host too, but it's
+  a credential *broker* for outbound API calls, not an agent runtime, and its
+  managed tier + 50+ integrations are oriented at public SaaS — it doesn't put
+  the agent behind your firewall for you. This is a reach advantage, distinct
+  from the isolation ones above, and it's a wedge cloud-first agent products
+  (Devin, Copilot Workspace, OneCLI Cloud) structurally can't match. **Tactical
+  read:**
+  adopt OneCLI's OSS core for the credential slice if building is undesirable
+  (it's mature now); don't build atop its managed tier (competitor, not
+  dependency); re-position bot-bottle on isolation + fleet + self-hosted custody
+  rather than "we hide your secrets."
