|
||||
|
||||
On compatible macOS hosts, the default backend requires Apple's `container` CLI and does not require Docker. The smolmachines backend requires Docker on the host for the sidecar bundle plus smolvm. 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`.

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 Apple Container is not installed and Docker is the desired backend.
|
||||
|
||||
### smolmachines on Linux
|
||||
|
||||
The smolmachines backend runs on Linux as well as macOS. On Linux, `smolvm`/libkrun use KVM, so the host 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.
|
||||
- **`smolvm`** on `PATH`: `curl -sSL https://smolmachines.com/install.sh | sh`.
|
||||
- **Docker** for the sidecar bundle and image build, same as macOS.
|
||||
|
||||
Per-bottle isolation works the same as macOS without any `ifconfig`/sudo step — all of `127.0.0.0/8` is already loopback on Linux, so each bottle's sidecar bundle is published on its own `127.0.0.<N>` and TSI's allowlist is scoped to that `/32`.
|
||||
|
||||
```sh
|
||||
BOT_BOTTLE_BACKEND=smolmachines ./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. If you run bottles from a Gitea Actions runner, use a `host`-label runner so Docker, `smolvm`, and `/dev/kvm` are all reachable from the job. `smolvm` isn't in nixpkgs — install the release binary (pin the version) and put it on the runner's `PATH`.

# ADR 0004: Risk-weighted coverage, not a single global target
|
||||
|
||||
- **Status:** Accepted
|
||||
- **Date:** 2026-06-25
|
||||
- **Deciders:** didericis
|
||||
|
||||
## Context
|
||||
|
||||
bot-bottle is a security tool: it sandboxes agents, scans egress for
|
||||
secret exfiltration, strips credentials, and gates git pushes. A latent
|
||||
bug in that logic is expensive, so test coverage there genuinely
|
||||
matters. But the repo also contains code where coverage is a poor
|
||||
signal:
|
||||
|
||||
- **Interactive entry-point shells** — `cli/init.py` (a `read_tty_line()`
|
||||
prompt loop) and `cli/tui.py` (a curses picker). Their bodies are I/O;
|
||||
a unit test has to fake the entire terminal conversation, so it
|
||||
inflates the number without asserting behaviour that would otherwise
|
||||
go unchecked.
|
||||
- **Subprocess / backend orchestration** — the docker / smolmachines /
|
||||
macos-container backends shell out to `docker`, `container`, `smolvm`.
|
||||
Mock-heavy unit tests here mostly re-assert the argv you already
|
||||
wrote (the test passes whether or not the real teardown works), while
|
||||
many of the missed *branches* are failure paths you cannot provoke
|
||||
against a real daemon on cue.
|
||||
|
||||
Chasing a single global percentage (e.g. 90%) pushes the most test
|
||||
effort onto the least safety-relevant code — exactly backwards — and
|
||||
invites performative tests written to colour a line rather than to catch
|
||||
a regression (Goodhart's law).
|
||||
|
||||
## Decision
|
||||
|
||||
Coverage is **risk-weighted**, measured over the **combined unit +
|
||||
integration** suites, with three rules:
|
||||
|
||||
1. **Critical modules target ≥ 90%.** The security/logic core —
|
||||
`egress_addon{,_core}.py`, `dlp_detectors.py`, `egress.py`,
|
||||
`manifest*.py`, `git_gate.py`, `git_http_backend.py`, `supervise.py`,
|
||||
`yaml_subset.py`, `bottle_state.py` — is Docker-independent and
|
||||
unit-testable, so it carries the high bar. We ratchet toward 90% as
|
||||
these modules are touched; new gaps in them are not acceptable.
|
||||
|
||||
2. **Subprocess/backend orchestration is covered by the integration
|
||||
suite, not omitted.** `scripts/coverage.sh` runs unit + integration
|
||||
under one coverage measurement so these modules are scored where they
|
||||
are actually exercised. They stay *visible* — hiding the code that
|
||||
tears down sandboxes and wires networks is the one place we will not
|
||||
omit.
|
||||
|
||||
3. **Interactive entry-point shells are omitted** (`.coveragerc`), with a
|
||||
rationale comment. This is the only sanctioned use of `omit` besides
|
||||
`tests/*`.
|
||||
|
||||
The forward-looking guard is a **diff-coverage gate**
|
||||
(`scripts/diff_coverage.py`): new/changed executable lines on a branch
|
||||
must be ≥ 90% covered. This catches regressions where they are
|
||||
introduced without forcing a back-fill crusade through legacy glue. The
|
||||
gate skips lines in omitted files (there is no coverage data for them),
|
||||
so the omit list cannot launder *new* logic into the dark: anything that
|
||||
needs real testing must live outside the interactive shells to be
|
||||
scored at all.
|
||||
|
||||
The **global percentage is informational**, not a CI gate — it would
|
||||
otherwise be hostage to the CI runner's Docker availability and to the
|
||||
omit list.
|
||||
|
||||
## Consequences
|
||||
|
||||
- The number we report (`scripts/coverage.sh`) means "coverage of the
|
||||
code we consider testable, across both suites" — a dip is a real
|
||||
regression in code we control, not noise from added CLI glue.
|
||||
- No incentive to write mock-the-mock tests for orchestration to defend
|
||||
a global figure.
|
||||
- The omit list needs governance: an entry must be a genuinely
|
||||
interactive shell, justified in the `.coveragerc` comment and here.
|
||||
`cli/init.py` and `cli/tui.py` qualify; backend orchestration does
|
||||
not.
|
||||
- CI must run the integration suite under coverage to score the
|
||||
orchestration modules; where the runner lacks Docker those tests skip
|
||||
and their modules read low — accepted, because the *enforced* gates
|
||||
(critical-module standard + diff coverage) are Docker-independent.
|
||||
- "We're at N%" is now a curated figure; outsiders should read the
|
||||
policy, not just the badge.

# PRD prd-new: smolmachines backend on Linux
|
||||
|
||||
- **Status:** Draft
|
||||
- **Author:** Claude
|
||||
- **Created:** 2026-06-25
|
||||
- **Issue:** #283
|
||||
|
||||
## Summary
|
||||
|
||||
Make the `smolmachines` backend (PRD 0023) runnable on Linux, not
|
||||
just macOS. `smolvm` already supports Linux via KVM (`/dev/kvm`);
|
||||
the gap is entirely in bot-bottle's host-side glue, which hard-codes
|
||||
macOS assumptions in three places:
|
||||
|
||||
1. **Preflight** only checks that `smolvm` is on `PATH` — it never
|
||||
checks the Linux KVM prerequisite, so a misconfigured host fails
|
||||
deep in the launch flow with an opaque `smolvm` error.
|
||||
2. **The TSI allowlist enforcement** (`force_allowlist`) — the
|
||||
security property that confines the agent VM to its sidecar
|
||||
bundle's `/32` — **no-ops on Linux today, failing _open_**. The
|
||||
smolvm state-DB path it patches is hard-coded to macOS's
|
||||
`~/Library/Application Support/...`.
|
||||
3. **Per-bottle loopback scoping** (`allocate`) returns the shared
|
||||
`127.0.0.1` on Linux, which would let the agent VM reach every
|
||||
service on host loopback — a downgrade from the per-bottle alias
|
||||
isolation macOS gets.
|
||||
|
||||
This PRD closes all three so a bottle launched with
|
||||
`BOT_BOTTLE_BACKEND=smolmachines` on Linux gets the same isolation
|
||||
guarantee it gets on macOS, and documents the Linux/NixOS host
|
||||
setup. The primary validation target is NixOS, but the changes are
|
||||
distro-agnostic.
|
||||
|
||||
## Problem
|
||||
|
||||
The smolmachines backend runs each bottle's agent inside a libkrun
|
||||
microVM via `smolvm`, with egress confined by TSI's `--allow-cidr`
|
||||
allowlist set to a single `/32` — the sidecar bundle's loopback
|
||||
address. Everything else (host loopback, LAN, internet) is denied at
|
||||
the VMM layer. That security property is the entire reason the
|
||||
backend exists.
|
||||
|
||||
libkrun runs on Hypervisor.framework (macOS) **and** KVM (Linux), and
|
||||
`smolvm` ships Linux x86_64 / aarch64 builds that require `/dev/kvm`.
|
||||
So the microVM layer already works on Linux. What does not work is
|
||||
bot-bottle's host integration, which PRD 0023 explicitly scoped to
|
||||
macOS-only for v1. Three concrete blockers:
|
||||
|
||||
- **No KVM preflight.** On a Linux host without `/dev/kvm` (kernel
|
||||
module not loaded) or without access to it (user not in the `kvm`
|
||||
group), the failure surfaces as a cryptic `smolvm` non-zero exit
|
||||
mid-launch instead of an actionable message.
|
||||
|
||||
- **TSI enforcement fails open on Linux.** `force_allowlist`
|
||||
early-returns on non-macOS. It exists because `smolvm` 0.8.0
|
||||
silently drops `--allow-cidr` when combined with `--from`, so the
|
||||
allowlist has to be patched into smolvm's persisted state DB before
|
||||
`machine start`. On Linux that patch never runs **and** the DB path
|
||||
is the macOS path, so the booted VM's TSI allowlist is whatever
|
||||
smolvm defaulted to — potentially all of `127.0.0.0/8`. That is the
|
||||
exact sandbox-escape the backend is supposed to prevent.
|
||||
|
||||
- **No per-bottle loopback isolation on Linux.** `allocate` returns
|
||||
`127.0.0.1` on Linux. Even with a correct allowlist, `127.0.0.1/32`
|
||||
is shared by every service on host loopback, so the agent could
|
||||
reach other bottles' published ports and host services. On macOS
|
||||
this is solved with per-bottle `127.0.0.16..31` aliases added via
|
||||
`sudo ifconfig lo0 alias`. On Linux the whole `127.0.0.0/8` is
|
||||
already routed to `lo`, so docker can publish to `127.0.0.<N>`
|
||||
with **no `ifconfig`/sudo step at all** — the isolation is actually
|
||||
cheaper to achieve than on macOS.
|
||||
|
||||
## Goals / Success Criteria
|
||||
|
||||
- `BOT_BOTTLE_BACKEND=smolmachines ./cli.py start <agent>` launches,
|
||||
runs, and tears down a bottle on a Linux host with `/dev/kvm`.
|
||||
- The TSI allowlist is enforced on Linux: PRD 0022's
|
||||
`tests/integration/test_sandbox_escape.py` passes against
|
||||
`BOT_BOTTLE_BACKEND=smolmachines` on Linux (the acceptance gate).
|
||||
- Each Linux bottle is scoped to its own `127.0.0.<N>/32`, matching
|
||||
the macOS per-bottle isolation property.
|
||||
- A clear, actionable preflight error when `/dev/kvm` is missing or
|
||||
inaccessible, with remediation (load `kvm-intel`/`kvm-amd`, join the
|
||||
`kvm` group).
|
||||
- **Fail-closed:** if bot-bottle cannot positively confirm the TSI
|
||||
allowlist was persisted for a machine (DB missing, row missing,
|
||||
patch didn't take), it `die()`s before `machine start` rather than
|
||||
booting a VM with an unverified allowlist.
|
||||
- macOS behavior is unchanged.
|
||||
- README documents Linux + NixOS host setup.
|
||||
|
||||
## Non-goals
|
||||
|
||||
- Rootless / non-KVM fallbacks (e.g. software emulation). Linux
|
||||
smolmachines requires `/dev/kvm`, full stop.
|
||||
- Removing Docker as a host dependency — the sidecar bundle and
|
||||
image-build pipeline still use Docker on Linux, same as macOS.
|
||||
- Auto-installing `smolvm` or configuring KVM on the operator's
|
||||
behalf. Preflight reports; the operator remediates.
|
||||
- Nested-virtualization tuning for running the runner itself inside a
|
||||
VM (documented as a caveat, not solved here).
|
||||
|
||||
## Design
|
||||
|
||||
### Platform detection
|
||||
|
||||
Reuse the existing `platform.system()` check already in
|
||||
`loopback_alias.py` (`_is_macos()`). "Linux" is "not macOS" for every
|
||||
branch below; no new third-platform path.
|
||||
|
||||
### Preflight: KVM gate (`util.smolmachines_preflight`)
|
||||
|
||||
After the existing `smolvm`-on-`PATH` check, add a Linux-only gate:
|
||||
|
||||
- `/dev/kvm` must exist → else `die()` with "enable KVM
|
||||
(`kvm-intel`/`kvm-amd` kernel module)".
|
||||
- `/dev/kvm` must be readable + writable by the current user
|
||||
(`os.access(..., R_OK | W_OK)`) → else `die()` with "add your user
|
||||
to the `kvm` group (and re-login)".
|
||||
|
||||
macOS is unaffected (Hypervisor.framework needs no device node).
|
||||
|
||||
### smolvm state-DB path (platform-aware)
|
||||
|
||||
`loopback_alias._SMOLVM_DB_PATH` becomes platform-derived:
|
||||
|
||||
- macOS: `~/Library/Application Support/smolvm/server/smolvm.db`
|
||||
(unchanged).
|
||||
- Linux: `$XDG_DATA_HOME/smolvm/server/smolvm.db`, defaulting to
|
||||
`~/.local/share/smolvm/server/smolvm.db`.
|
||||
|
||||
> **Verification note:** the Linux DB location is inferred from
|
||||
> smolvm's documented `~/.local/share` install layout and the XDG
|
||||
> base-dir spec. It must be confirmed on a real Linux smolvm install;
|
||||
> if smolvm uses a different path or schema, the fail-closed check
|
||||
> below turns that into a clear `die()` at launch rather than a silent
|
||||
> escape.
|
||||
|
||||
### TSI enforcement: cross-platform + fail-closed (`force_allowlist`)
|
||||
|
||||
Rework `force_allowlist(machine_name, allowed_cidrs)` to run on
|
||||
**both** platforms and to fail closed:
|
||||
|
||||
1. Resolve the state DB; if the file is missing, `die()` (cannot
|
||||
confirm enforcement → refuse to launch).
|
||||
2. Read the machine's persisted row; if the row is missing, `die()`.
|
||||
3. If the row's `allowed_cidrs` already equals the requested list
|
||||
(e.g. a newer `smolvm` that honors `--allow-cidr` at create), do
|
||||
nothing — no write.
|
||||
4. Otherwise patch `allowed_cidrs` (the existing BLOB-encoded write)
|
||||
and re-read.
|
||||
5. If, after the patch, `allowed_cidrs` still does not equal the
|
||||
requested list, `die()`.
|
||||
|
||||
This is robust across smolvm versions: it works whether `--allow-cidr`
|
||||
is silently dropped (0.8.0) or honored (newer), and it never boots a
|
||||
VM whose persisted allowlist it could not confirm. It is a strict
|
||||
improvement on macOS too (today's code writes unconditionally and
|
||||
never verifies).
|
||||
|
||||
> The persisted-row check confirms our write took, not that smolvm's
|
||||
> runtime TSI enforces it. The runtime guarantee is covered by the
|
||||
> sandbox-escape acceptance test; the persisted check is the cheap
|
||||
> fail-closed guard at launch.
|
||||
|
||||
### Per-bottle loopback scoping on Linux (`allocate`)
|
||||
|
||||
`allocate` runs the same docker-state-driven allocation on Linux as on
|
||||
macOS (`_allocate_locked`, the file lock, and `_aliases_in_use` via
|
||||
`docker inspect` are all already cross-platform). The only macOS-only
|
||||
step, `ensure_pool` (the `sudo ifconfig lo0 alias` dance), stays
|
||||
macOS-only: on Linux `127.0.0.0/8` is already loopback, so docker can
|
||||
publish bundle ports directly on `127.0.0.<N>` with no setup.
|
||||
|
||||
Net effect: Linux bottles get per-bottle `127.0.0.16..31/32` scoping
|
||||
identical to macOS, without sudo.
|
||||
|
||||
### Launch flow
|
||||
|
||||
`launch.py` needs no structural change — `_allocate_resources` already
|
||||
calls `ensure_pool()` (now a Linux no-op) then `allocate()` (now
|
||||
per-bottle on Linux), and `_launch_vm` already calls
|
||||
`force_allowlist()` (now active on Linux). Only the macOS-specific
|
||||
docstrings are updated to describe the cross-platform behavior.
|
||||
|
||||
## Implementation chunks
|
||||
|
||||
1. **Preflight KVM gate** — `util.smolmachines_preflight` +
|
||||
unit tests for the missing-device and no-access branches.
|
||||
2. **Platform-aware DB path + fail-closed `force_allowlist`** —
|
||||
`loopback_alias.py`; update/extend `TestForceAllowlist`.
|
||||
3. **Cross-platform `allocate`** — drop the Linux early-return; update
|
||||
`TestAllocate` / `TestAllocateLock` for the new Linux behavior.
|
||||
4. **Docstring + comment cleanup** in `launch.py` and module headers.
|
||||
5. **Docs** — README requirements + a Linux/NixOS host-setup section.
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
- **Unit (CI, any OS):** the suite mocks `platform.system()` /
|
||||
`subprocess` and patches `_SMOLVM_DB_PATH`, so the new Linux
|
||||
branches are testable on the macOS/Linux CI runner without `smolvm`
|
||||
or KVM. Covers: KVM preflight branches, fail-closed `force_allowlist`
|
||||
(DB missing, row missing, patch-doesn't-take), per-bottle Linux
|
||||
allocation + locking, platform-derived DB path.
|
||||
- **Integration (Linux host with KVM — the acceptance gate):**
|
||||
`tests/integration/test_sandbox_escape.py` against
|
||||
`BOT_BOTTLE_BACKEND=smolmachines`. This cannot run on the macOS dev
|
||||
box and must be executed on NixOS before merge.
|
||||
|
||||
## Open questions / verification pending
|
||||
|
||||
- **Confirm the Linux smolvm state-DB path and schema** on a real
|
||||
install (the `~/.local/share/...` inference above).
|
||||
- **Confirm whether the current smolvm Linux build still drops
|
||||
`--allow-cidr` with `--from`** (the 0.8.0 bug). The fail-closed
|
||||
design handles either answer, but knowing lets us drop the DB patch
|
||||
if upstream fixed it.
|
||||
- **Confirm docker publishing to `127.0.0.<N>` on Linux** behaves as
|
||||
expected end-to-end with TSI (high confidence; standard loopback
|
||||
behavior, but unverified on the target host).

"""Diff-coverage gate (see docs/decisions/0004-coverage-policy.md).
|
||||
|
||||
Fails if too few of the *added/changed* executable lines on this branch
|
||||
are covered. Stdlib-only by design — the project carries no runtime deps
|
||||
and we are not adding `diff-cover` to satisfy a check.
|
||||
|
||||
Reads coverage data already produced by a `coverage run` (e.g. via
|
||||
`scripts/coverage.sh`): it shells out to `coverage json` for per-line
|
||||
data and to `git diff` for the changed lines. Lines in omitted files
|
||||
(the interactive shells) have no coverage data and are skipped, by
|
||||
policy.
|
||||
|
||||
Usage:
|
||||
scripts/coverage.sh # produce .coverage first
|
||||
python3 scripts/diff_coverage.py # gate against origin/main, min 90%
|
||||
python3 scripts/diff_coverage.py --base main --min 85
