test: update PipelockRoutePolicy tests for Config dict design

Replace typed-attribute assertions (TlsPassthrough, SsrfIpAllowlist)
with Config dict lookups, drop the four strict-validation tests that
were intentionally removed in the refactor, and add a
skip_scan_for_extensions test to cover the PR's stated new feature.

-bot-bottle spins up an isolated backend runtime for running AI coding agents
-with a curated set of skills and env vars. The point is to run agents with
-broad permissions inside a sandbox, so a misbehaving agent cannot reach the
-host. A Python CLI (entry point `cli.py`, package `bot_bottle/`) orchestrates
-the runtime lifecycle and the copying of skills and env vars into it.
-The default backend on compatible macOS hosts is macos-container:
-agents and gateways run through Apple's `container` CLI without
-requiring Docker. On KVM-capable Linux hosts the default is firecracker:
-agents run in a Firecracker microVM reached over SSH on a point-to-point
-TAP, while the gateway still uses Docker. The legacy Docker
-backend remains available with `BOT_BOTTLE_BACKEND=docker` or
-`--backend=docker`.

 ## Features
 
-- **Per-bottle egress allowlist** — TLS-bumped HTTP/HTTPS chokepoint with a per-manifest host allowlist; per-route path/method/header `matches` filtering; outbound DLP scanning for known tokens and secrets, inbound DLP scanning for prompt-injection attempts; DoH and arbitrary hosts blocked by default.
-- **Per-route token-match policy** — each egress route picks what happens when the outbound DLP catches a token via `dlp.outbound_on_match`: `supervise` (default) holds the request and surfaces it in `./cli.py supervise` for approval (an approved value is remembered for the life of the proxy); `redact` scrubs the value and forwards; `block` is a hard `403`. Cuts false-positive friction without weakening default-deny.
-- **Tokens the agent never sees** — host secrets live in a gateway; the agent dials `http://gateway:9099/<path>` and the proxy strips inbound `Authorization` and injects the real token before forwarding. `printenv` in the agent shows proxy URLs only.
+- **Per-bottle egress allowlist** — TLS-bumped HTTP/HTTPS chokepoint with a per-manifest host allowlist and request-body DLP scanner; DoH and arbitrary hosts blocked by default.
+- **Tokens the agent never sees** — host secrets live in a sidecar; the agent dials `http://sidecar:9099/<path>` and the proxy strips inbound `Authorization` and injects the real token before forwarding. `printenv` in the agent shows proxy URLs only.
 - **Gitleaks-scanned push (git-gate)** — `bottle.git` remotes route through a per-bottle `git daemon` that gitleaks-scans incoming refs pre-receive and forwards clean refs upstream over SSH. The agent never holds the upstream credential.
 - **Manifest-scoped skills + secrets** — each bottle declares its skills, env, git identity, remotes, and egress routes; unknown keys die at load.
 - **Trust boundary at `$HOME`** — bottles (credentials, egress, remotes) live only under `~/.bot-bottle/bottles/`. Repos may ship agents but not bottles, so a cloned repo can't redirect an env var to an attacker host.
 - **Composable bottles (`extends:`)** — keep provider/runtime policy in one base bottle (e.g. `claude.md`) and overlay task bottles on top.
-- **Parallel, isolated bottles** — each bottle runs in its own backend-owned isolation boundary; bottles don't share state or talk to each other.
+- **Parallel, isolated bottles** — each bottle is its own per-agent Docker `--internal` network; bottles don't share state or talk to each other.
 - **Provider templates (Claude, Codex)** — `Dockerfile.claude` / `Dockerfile.codex`, or a bottle-supplied Dockerfile. Claude auth via long-lived OAuth token; Codex via opt-in host device-auth forwarding.
 - **gVisor auto-detect** — on Linux hosts where `runsc` is registered with Docker, every bottle launches under it for a userspace syscall barrier; no manifest config required.
-- **Apple Container backend (macOS default when available)** — runs the agent and gateway with Apple's `container` CLI, using a host-only agent network plus a separate gateway egress network.
-- **Firecracker backend (Linux default when available)** — runs the agent in a KVM Firecracker microVM reached over SSH on a point-to-point TAP, with the gateway in Docker. A dedicated, fail-closed `nftables` table isolates the guest, closing the raw DNS/IP exfiltration gap that exists in the legacy Docker backend. Requires KVM (`/dev/kvm`) and a one-time privileged network-pool setup.
-- **Legacy Docker backend** — still available for examples, CI, and hosts without Apple Container or KVM via `BOT_BOTTLE_BACKEND=docker` or `--backend=docker`.
+- **Smolmachines backend (macOS)** — opt-in `BOT_BOTTLE_BACKEND=smolmachines` runs the agent in a libkrun micro-VM with the sidecar bundle still in Docker.
 
 ## Architecture
 
-On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a gateway 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 gateway's internal-network IP, so HTTP/HTTPS traffic flows through the gateway instead of direct egress. `bottle.git` / git-gate is intentionally deferred on this backend until a safe Apple Container key-delivery path exists.
-
-On the Firecracker backend, a bottle is an agent microVM plus a Docker gateway for egress, git-gate, and supervise. The VM reaches the gateway over a per-bottle point-to-point TAP link; a dedicated fail-closed `nftables` table (`inet bot_bottle_fc`) confines the guest to that link, so nothing leaves the box except through the gateway. The TAP pool and nft table are provisioned once (root); per-launch needs no privilege.
-
-On the legacy Docker backend, the same logical bottle is two containers per agent: an `agent` container and a `companion containers` container. They share a per-agent Docker `--internal` network; the agent has no default route off-box.
-
-The Docker topology looks like this:
+A bottle is two containers per agent: an `agent` container, and a `sidecars` container that bundles pipelock + cred-proxy + git-gate + supervise behind a Python init supervisor. They share a per-agent Docker `--internal` network; the agent has no default route off-box.

+When the agent exits, `cli.py` tears down every sidecar and both networks; nothing about a bottle persists between runs.
 
 ## Quickstart
 
-On compatible macOS hosts, the default backend requires Apple's `container` CLI and does not require Docker. The Firecracker backend (Linux) requires Docker on the host for the gateway plus the `firecracker` binary and KVM. The legacy Docker backend requires Docker. Claude bottles also need a long-lived Claude Code OAuth token (`claude setup-token`) exported as `BOT_BOTTLE_CLAUDE_OAUTH_TOKEN`.
-
-Use `BOT_BOTTLE_BACKEND=docker ./cli.py start <agent>` on hosts where neither Apple Container nor KVM is available and Docker is the desired backend.
-
-### Firecracker on Linux
-
-On Linux, a KVM-capable host defaults to the Firecracker backend. It needs:
-
-- **`/dev/kvm`** present and accessible. Load `kvm-intel` or `kvm-amd` (and enable virtualization in BIOS/firmware). The invoking user must be in the `kvm` group: `sudo usermod -aG kvm "$USER"` then re-login. bot-bottle preflights this and reports exactly what's missing.
-- **`firecracker`** on `PATH`: grab a release from <https://github.com/firecracker-microvm/firecracker/releases>. Start flows print this pointer when the binary is missing.
-- **Docker** for the gateway and image build.
-- **A one-time privileged network setup** — the per-bottle TAP pool plus the fail-closed `nftables` isolation table. Run `./cli.py backend setup --backend=firecracker` for the host-appropriate config (a NixOS module, a `sudo` script elsewhere); `./cli.py backend status --backend=firecracker` reports what's present, including whether the pool range collides with an existing route. The pool defaults to `10.243.0.0/16` (an obscure RFC-1918 block that dodges docker/libvirt/LAN and, deliberately, Tailscale's `100.64.0.0/10` CGNAT range); override with `BOT_BOTTLE_FC_IP_BASE` if it clashes on your host.
-
-```sh
-BOT_BOTTLE_BACKEND=firecracker ./cli.py start <agent>
-```
-
-> **NixOS:** enable `virtualisation.docker`, ensure the KVM module is loaded (`boot.kernelModules = [ "kvm-intel" ];` or `kvm-amd`), and add your user to the `kvm` and `docker` groups. For the network pool, consume the flake module — `imports = [ inputs.bot-bottle.nixosModules.firecracker-netpool ]; services.bot-bottle-firecracker = { enable = true; owner = "you"; };` — then `nixos-rebuild switch` (imperative nft/TAP rules don't survive a rebuild; channel users can `imports = [ <bot-bottle>/nix/firecracker-netpool.nix ]`). `firecracker` isn't in nixpkgs by default as a user binary — install the release binary (pin the version) and put it on `PATH`.
+Requires Docker on the host and a long-lived Claude Code OAuth token (`claude setup-token`) exported as `BOT_BOTTLE_CLAUDE_OAUTH_TOKEN`.

-**Egress route fields:**
-
-| Field | Required | Description |
-|---|---|---|
-| `host` | yes | Hostname to allowlist. One entry per host. |
-| `role` | no | Reserved for future use. The key is recognised but any value is currently rejected at load. Provider auth routes (e.g. Claude's `api.anthropic.com`) are injected automatically from `agent_provider.auth_token`, not via `role`. |
-| `auth.scheme` | when `auth` present | `Bearer` or `token`. Injected by the proxy; the agent never sees the value. |
-| `auth.token_ref` | when `auth` present | Env-var name holding the secret on the host. |
-| `matches` | no | Array of `{paths, methods, headers}` filters. A request must match at least one entry (if any are given) to be forwarded. |
-| `matches[].paths` | no | Array of `{type, value}`. `type` is `prefix` (default), `exact`, or `regex`. |
-| `matches[].methods` | no | Array of HTTP method strings, e.g. `[GET, POST]`. |
-| `matches[].headers` | no | Array of `{name, value, type}`. `type` is `exact` (default) or `regex`. |
-| `dlp` | no | Per-route DLP overrides. Omit to use defaults (all detectors on). |
-| `dlp.outbound_detectors` | no | `false` disables outbound scanning; list restricts to named detectors (`token_patterns`, `known_secrets`). |
-| `dlp.inbound_detectors` | no | `false` disables inbound scanning; list restricts to named detectors (`naive_injection_detection`). |
-| `dlp.outbound_on_match` | no | What to do when an outbound token is detected: `supervise` (default for manifest routes — hold for operator approval), `redact` (scrub the value and forward), or `block` (hard 403). Agent-provider routes (e.g. `api.anthropic.com`) default to `redact`. |
-| `git.fetch` | no | `true` permits smart HTTP clone/fetch (`git-upload-pack`) for this host. Push (`git-receive-pack`) remains blocked. |
-
-When an outbound DLP detector matches a token, the route's `dlp.outbound_on_match` policy decides what happens. Under the default `supervise`, the proxy queues an `egress-token-allow` proposal for the operator's `./cli.py supervise` TUI and holds the request open until it is answered (or `EGRESS_TOKEN_ALLOW_TIMEOUT_SECONDS`, default 300s, elapses — after which it fails closed). The operator never sees the raw token, only the host, method, path, and a redacted snippet; approving adds the value to an in-memory safelist for the life of the egress proxy. Under `redact`, the matched value is scrubbed from the body, headers, and path and the request is forwarded (failing closed if a match lands somewhere unredactable, like the hostname). Under `block` it stays a hard `403`. Structural blocks (CRLF injection) and not-in-allowlist host blocks are always hard `403`s regardless of policy.

-Serialize a compose spec to disk, drive `docker compose up/down`,
-dump the merged log on teardown, and enumerate `bot-bottle-*`
-projects. The spec itself is built by `consolidated_compose.py`
-(the consolidated per-host gateway topology); this module owns the
-I/O side that persists and runs it.
+`bottle_plan_to_compose(plan)` returns a Compose v2 spec dict
+describing the per-bottle container topology — one project per
+bottle instance, services for the agent + every applicable sidecar,
+two networks, no named volumes.
+
+Pure function. No I/O, no subprocess. Expects every launch-time
+field (network names, CA host paths, etc.) on the plan's inner
+plans to be populated; chunks 2+3 own that ordering. Chunk 1 just
+encodes the translation so it can be unit-tested in isolation.
+
+Conditional services follow the plan content (matches the
+SDK-call branching in `launch.py` today):
+
+  - pipelock + agent: always.
+  - git-gate:         iff plan.git_gate_plan.upstreams.
+  - egress:           iff plan.egress_plan.routes.
+  - supervise:        iff plan.supervise_plan is not None.
+
+Naming:
+
+  - Compose project: `bot-bottle-<slug>`.
+  - Service names (inside the file): `agent`, `pipelock`,
+    `egress`, `git-gate`, `supervise`.
+  - `container_name:` matches today's pattern
+    (`bot-bottle-<service>-<slug>`) so dashboard/cleanup discovery
+    via the prefix scan keeps working through the transition.
+  - Network aliases preserve the current dial-by-shortname pattern
+    for `egress` / `supervise`, and add the long container-name as
+    an internal-network alias for `pipelock` / `git-gate` so any
+    caller still referencing the long name resolves.
+
+Sidecars that are built (egress, git-gate, supervise) get a
+compose `build:` block pointing at the repo Dockerfile; the
+`image:` tag is set explicitly so cached images on the daemon
+aren't rebuilt on every up.

+Post-PRD-0017 the CA depends on the agent's HTTP_PROXY target:

+
+By the time this provisioner runs, the corresponding `tls_init`
+helper has generated the chosen CA under `plan.stage_dir`, and the

+(`NODE_EXTRA_CA_CERTS`) and Python `requests` /
+`SSL_CERT_FILE`-honoring libraries that don't load the system
+bundle.

-"""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

-"""Firecracker network pool: constants, IP math, allocation, and the

-
-The Firecracker backend needs a privileged one-time network setup:
-a pool of point-to-point TAP devices (owned by the invoking user, so
-`./cli.py start` never needs root) and a dedicated nftables table that
-isolates every VM. The pool parameters live in exactly one place —
-`netpool.defaults.env`, a plain KEY=VALUE file next to this module —
-and every consumer reads *that*: this module (below), the shell script
-(`scripts/firecracker-netpool.sh`), and the NixOS module
-(`nix/firecracker-netpool.nix`). A `BOT_BOTTLE_FC_*` env var of the
-same name always overrides the file, and the backend's fail-closed
-preflight derives from these accessors, so nothing can drift.
-
-Topology (per slot i):
-  * TAP  ``bbfc{i}``  — no shared bridge, so no docker0 / virbr0 / cni0
-    / br-* collisions.
-  * a /31 host<->guest link: host = base + 2i (the gateway the VM
-    routes through), guest = base + 2i + 1 (the VM's address).
-  * isolation via ``table inet bot_bottle_fc``: a VM reaches only its
-    own gateway (DNAT'd from the host TAP IP) and nothing else.
-
-The default IP block is ``10.243.0.0/16`` — an intentionally obscure
-corner of RFC-1918 private space. RFC-1918 is the range *designated*
-for private links; we pick a high, unusual /16 to steer clear of the
-common occupants (Docker's 172.17-31, libvirt's 192.168.122, k8s
-10.42/10.244, and typical home LANs on 192.168.0/1.x or 10.0.0.x).
-We deliberately avoid ``100.64.0.0/10`` (RFC-6598 CGNAT) because
-Tailscale hands out node addresses from exactly that range. No default
-is collision-proof, so `overlapping_routes()` is the real guard —
-`backend setup`/`status` and the launch preflight call it to catch
-a base that clashes with something already on the host.

-locally — `docker build` the three fixed images, export to a rootfs dir, inject
-the guest boot, `mke2fs` to an ext4 with the buildah build slack — then gzips
-the ext4 and PUTs it (plus a `.sha256`) to
-`…/api/packages/<owner>/generic/bot-bottle-firecracker-infra/<version>/`.
-
-The `<version>` is `infra_artifact.infra_artifact_version(...)`, the content
-hash of the rootfs inputs, so a launch host at the same code checkout resolves
-the exact artifact this produced.
-
-  python3 -m bot_bottle.backend.firecracker.publish_infra [--dry-run] [--force]
-
-Auth: a token with `write:package` on the target owner, from
-`BOT_BOTTLE_INFRA_ARTIFACT_TOKEN`.

-"""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).
-
-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.

+exit.

+PipelockProxyPlan; egress reads routes + CAs from the EgressPlan
++ EGRESS_UPSTREAM_PROXY pointing at `127.0.0.1:8888` (bundle
+local), since the agent dials pipelock first (not egress) on the
+smolmachines path. Git-gate + supervise plumb through the same
+plans the docker backend uses, minus the docker-network fields

+"""Ephemeral local OCI registry for the smolmachines agent-image
+conversion path (PRD 0023 chunk 4c).
+
+`smolvm pack create --image <ref>` only accepts OCI registry refs
+— it can't read the local docker daemon's image cache, an OCI
+layout directory, or a `docker save` tarball. To convert the
+agent's Dockerfile-built image into a `.smolmachine` artifact we
+spin up a short-lived `registry:2.8.3` container alongside a
+`crane` helper container on a private docker network, push via
+`crane push --insecure <tarball> <registry-container>:5000/...`,
+and let smolvm pull from the registry's published host port. The
+network + both containers are torn down after the pack completes.
+
+Why this two-container dance instead of plain `docker push`:
+- Docker Desktop's daemon runs in its own Linux VM, so its
+  `localhost` is not the host's loopback. A registry bound to
+  the host's 127.0.0.1 is unreachable from the daemon side.
+- `host.docker.internal` is reachable from the daemon but isn't
+  in Docker's default insecure-registries CIDRs (only `::1/128`
+  and `127.0.0.0/8` are), so `docker push` to it tries HTTPS,
+  hits a plain-HTTP registry, and dies with
+  `http: server gave HTTP response to HTTPS client`. Adding
+  `host.docker.internal` to daemon.json works but is a one-time
+  manual step the user has to do in Docker Desktop's UI.
+- Going through a docker network sidesteps the host-vs-daemon
+  loopback mismatch (crane and registry containers see each
+  other on the network) AND the HTTPS preference (crane has an
+  `--insecure` flag that forces plain HTTP).
+
+The registry is also published on a random host port so smolvm
+— a host process — can pull from `localhost:<port>` via Docker's
+port-forward. smolvm's bundled crane auto-falls-back to HTTP for
+localhost addresses, so no insecure-registries config is needed
+on that side either."""
