-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 sidecar bundles 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 sidecar bundle 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.
+- **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 sidecar bundle with Apple's `container` CLI, using a host-only agent network plus a separate sidecar 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 sidecar bundle 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 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.
-
-On the Firecracker backend, a bottle is an agent microVM plus a Docker sidecar bundle for egress, git-gate, and supervise. The VM reaches the sidecars 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 sidecars. 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 `sidecars` 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 egress + git-gate + supervise behind a Python init supervisor. They share a per-agent Docker `--internal` network; the agent has no default route off-box.

 ## 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 sidecar bundle 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 sidecar bundle 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`.

-| 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.

 More examples in `examples/`. Full design lives under `docs/prds/`; the trust-boundary rationale is in `docs/prds/0011-per-file-md-manifest.md`.

-"""Firecracker network pool: constants, IP math, allocation, and the
-config renderers (shell command + NixOS module) shown to operators.
-
-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 sidecar (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.

-"""Host-side raw-mode wrapper for `container exec --interactive --tty`.
-
-Apple's `container exec --interactive --tty` does not set the host terminal to
-raw mode before starting its I/O relay.  Without raw mode the kernel line
-discipline buffers modifier-key escape sequences (e.g. Shift+Enter in
-modifyOtherKeys mode produces \\x1b[13;2~) until a carriage-return arrives, so
-they never reach Claude Code inside the container.
-
-This module sets the host terminal to raw mode, spawns the inner argv (the
-container exec command), and restores the original terminal attributes on
-exit.  When stdin is not a TTY (piped invocations, CI) it falls through to a
-bare subprocess.run so callers do not need to special-case non-interactive
-contexts.
-
-Usage (the `--` separator is the API contract — everything after it is the
-inner command):

+"""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."""

+"""Per-bottle loopback alias allocation + TSI allowlist
+enforcement (PRD 0023, follow-up to PR #74).
+
+After the pivot to host-loopback port-forwards, the smolmachines
+TSI allowlist was `127.0.0.1/32` — which meant the agent VM could
+reach **any** service bound to macOS's loopback, not just the
+bundle's published ports. Real downgrade from the docker
+backend's `--internal` network isolation.
+
+This module narrows the allowlist by allocating each bottle a
+unique loopback alias (`127.0.0.16` .. `127.0.0.31`). The
+bundle's port-forwards bind to that alias, and the alias's /32
+is what TSI allows.
+
+**Smolvm 0.8.0 quirk + workaround.** `smolvm machine create
+--from <smolmachine> --net --allow-cidr X/32` silently drops the
+flag — verified empirically that the agent process's allowlist
+ends up `null` in smolvm's persistent state DB (`~/Library/
+Application Support/smolvm/server/smolvm.db`, `vms` table,
+`data` BLOB), and the booted VM reaches all of `127.0.0.0/8`
+regardless of what we passed. Workaround: after machine_create,
+open the SQLite DB and patch the row's `allowed_cidrs` field
+directly. Smolvm reads the DB at machine_start, so the patched
+value takes effect on boot. Tested: enforcement is real — the
+guest's connect to a non-allowlisted IP fails with `Permission
+denied`. Other paths we tried (machine update, stop-edit-
+agent.config.json-restart, --smolfile, --image localhost:N/...)
+were dead ends.
+
+macOS only configures `127.0.0.1` on `lo0` by default; the
+additional aliases require `sudo ifconfig lo0 alias`. We lazily
+sudo-add the missing pool on first use per boot — the aliases
+persist on `lo0` until reboot, so subsequent launches don't
+prompt.
+
+Linux native daemons share the host's network namespace; the
+whole `127.0.0.0/8` is reachable by default and aliases are
+unnecessary. The pool logic detects native-Linux and skips sudo
+entirely; the DB patch is also gated on macOS.
+
+Allocation is coordinated by inspecting running bundle
+containers' published host IPs — each bottle's bundle owns the
+alias appearing in its port bindings. The lowest-numbered free
+alias gets handed to a new bottle."""

+"""Host-side SIGWINCH → in-VM PTY resize bridge (issue #82).
+
+smolvm 0.8.0 `machine exec -t` allocates an in-VM PTY but never
+forwards the host terminal's window size (TIOCSWINSZ) to it. The
+PTY's initial size is `0 0`, and any host-side resize during the
+session goes unnoticed — the in-VM claude TUI keeps rendering for
+whatever (typically tiny) box it last saw, ignoring the operator's
+tmux pane resize. `docker exec -it` does this forwarding
+automatically; smolvm doesn't.
+
+This module wraps `smolvm machine exec` with a thin parent
+process that:
+
+  1. Spawns the original argv as a child (it gets the inherited
+     TTY, so claude's stdin/stdout/stderr work unchanged).
+  2. On startup + every host SIGWINCH, reads the host terminal
+     size via TIOCGWINSZ on stdin (or stderr if stdin isn't a
+     TTY — tmux respawn-pane gives us a TTY on stdout/stderr)
+     and pushes it into the VM with a side-channel
+     `smolvm machine exec -- sh -c 'for f in /dev/pts/*; do
+     stty -F $f cols X rows Y; done'`. The kernel delivers
+     SIGWINCH to the foreground process group on the slave end
+     automatically, so claude picks up the new size without
+     extra signalling.
+  3. Waits on the child and exits with its returncode.
+
+The dashboard's tmux pane respawn calls `bottle.agent_argv`
+which now prepends `[sys.executable, -m, ..., <machine>, --, ...]`
+to the smolvm argv. Foreground handoff (curses endwin →
+subprocess.run) goes through the same path so behavior is
+identical.

+"""Thin subprocess wrapper around the `smolvm` CLI (PRD 0023).
+
+One thin Python function per smolvm subcommand the launch flow
+needs. Two design choices worth flagging:
+
+  - **No daemon, no SDK.** smolvm 0.8.0 ships a `smolvm serve`
+    HTTP API as the long-term-clean integration target. The
+    project's stdlib-first ethos + the lower-overhead CLI calls
+    push v1 to shell out via `subprocess.run`. If a future
+    smolvm release makes `serve` mandatory (or significantly
+    faster), revisit.
+
+  - **Two return shapes.** `SmolvmRunResult` (returncode + stdout
+    + stderr captured) is returned by `machine_exec` because the
+    caller cares about the in-VM command's exit status, and by
+    test helpers that introspect output. The other calls
+    (`machine_start`, `machine_stop`, `pack_create`, etc.) raise
+    `SmolvmError` on non-zero exit — failure to start a VM is
+    fatal to the launch flow, not something callers want to
+    branch on.
+
+The wrapper is unit-tested with `subprocess.run` mocked; the
+integration smoke test (chunk 2d) exercises against a real
+smolvm binary."""
