feat(smolmachines): run backend on Linux

Port the smolmachines backend so BOT_BOTTLE_BACKEND=smolmachines
works on Linux (KVM), not just macOS:

- Preflight gates /dev/kvm presence + accessibility on Linux with
  actionable remediation (kvm module, kvm group).
- smolvm state-DB path is platform-derived (XDG on Linux).
- force_allowlist runs on both platforms and is fail-closed: it
  verifies the persisted TSI allowlist and dies rather than booting
  a VM whose egress confinement it can't confirm. Previously it
  no-oped on Linux, failing OPEN.
- allocate() does per-bottle 127.0.0.<N> scoping on Linux too (no
  ifconfig needed — all of 127/8 is already loopback); only
  ensure_pool's lo0 aliasing stays macOS-only.
- README documents Linux + NixOS host setup.

Linux/KVM integration (the sandbox-escape acceptance gate) is
pending verification on a NixOS host; unit tests cover the new
platform branches.

Issue: #283

 ## Quickstart
 
-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`.

 ./cli.py start <agent>   # builds the image on first run, drops you into claude

-# 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.
-
-## Links
-
-- PRs #290 (cover the egress adapter), and the coverage-policy PR that
-  introduces this record.
-- `.coveragerc`, `scripts/coverage.sh`, `scripts/diff_coverage.py`.
-- `scripts/critical-modules.txt` — the single source of truth for the
-  core-module list; read by both `scripts/coverage.sh` and the
-  `update-badges.yml` "core coverage" badge so they cannot drift.
-- The README carries a `core coverage` badge (auto-updated from that
-  list) — the headline number, distinct from the informational global
-  `coverage` badge.

-# PRD prd-new: Forge native integration
-
-- **Status:** Draft
-- **Author:** claude
-- **Created:** 2026-06-29
-- **Issue:** #317
-
-## Summary
-
-Add a webhook-driven orchestration layer that lets Gitea issues and PR comments
-drive bot-bottle sessions end-to-end with no operator in the loop for the happy
-path. An issue assigned to a member of the configured agent org and labelled
-with an agent name triggers a headless bottle launch; the bottle processes the
-issue, opens a PR, and interacts with the forge through a **forge sidecar** —
-the agent never touches the Gitea API or its credentials directly. The agent
-calls `signal_done(status, summary)` on the sidecar when a work unit is
-complete; the sidecar relays that to the orchestrator over a queue dir (the same
-pattern as the supervise sidecar), so completion is an unambiguous in-band
-signal rather than a comment the orchestrator has to parse. The orchestrator
-freezes the bottle and attaches a provenance footer. Subsequent PR comments
-rehydrate the frozen bottle. The bottle is destroyed when the PR closes.
-
-The forge sidecar is backed by a `Forge` abstract class with per-provider
-implementations (Gitea first), so the agent's prompts and the sidecar protocol
-stay forge-agnostic. The sidecar logs forge operations semantically ("read PR
-description", "posted comment", "signalled done"), giving richer provenance than
-post-hoc egress-byte parsing, and enforces a **read-anywhere / write-scoped**
-permission model: the agent may read for context but may only write to the
-issue and PRs it was assigned.
-
-The separation of concerns across the two layers: bot-bottle owns the headless
-launch primitives, the forge sidecar + `Forge` abstraction, forge state, and the
-provenance builder. `bot-bottle-orchestrator` (separate binary) owns the webhook
-listener, bottle lifecycle loop, and monitoring dashboard; it calls into
-bot-bottle via `./cli.py orchestrate`, a thin wrapper command. This PRD covers
-bot-bottle's side of that contract.
-
-## Problem
-
-Today an operator must open the TUI, select an agent and bottle, confirm the
-preflight, and type prompts interactively. This blocks "issue → PR" automation
-and produces no durable audit record of what the agent did. The security model
-already provides the right isolation and egress controls, and `start --headless`
-(#315) already gives `bot-bottle-orchestrator` a non-interactive launch path.
-The missing pieces are a headless `resume` counterpart for rehydrating frozen
-bottles, a forge-interaction surface the agent uses to read context, post
-comments, and signal completion, and the provenance trail that makes the audit
-story legible to reviewers on every PR.
-
-That forge-interaction surface could be built two ways: (2) give the agent the
-Gitea API directly with cred-proxy injecting the token, or (3) put a forge
-sidecar between the agent and the forge. This PRD takes **option 3**. The
-deciding factors: a sidecar `signal_done` call is an unambiguous completion
-signal where comment-parsing is a correctness risk that surfaces in production;
-the sidecar produces a semantic audit trail rather than HTTP bytes, which is
-load-bearing for provenance (the stated product priority); and the sidecar can
-enforce scope tighter than repo-wide API-key permissions, reducing blast radius
-for a prompt-injected agent. The costs — a second sidecar process per forge run,
-a new failure mode if it crashes, and per-forge implementation cost — are
-accepted as the price of those properties.
-
-## Goals / Success Criteria
-
-1. Headless launch already exists: `./cli.py start <agent> --headless --prompt`
-   (#315) runs non-interactively with no TUI selectors or y/N preflight. This
-   PRD builds on it rather than re-introducing it. The remaining gap is a
-   matching headless `resume` path (`./cli.py resume --headless`), since
-   rehydrating a frozen bottle for a new prompt is required by the freeze /
-   rehydrate loop and `resume` has no non-interactive entry point today.
-2. An issue assigned to a member of the configured org (`FORGE_ORG`, default
-   `bot-bottle`) and labelled `bot-bottle:<agent-name>` is the trigger
-   convention. Org membership is verified via the Gitea API at event time.
-3. Forge-targeted bottles run a **forge sidecar** that exposes a small,
-   forge-agnostic API (comment/issue/PR CRUD plus `signal_done`) over the same
-   queue-dir + HTTP/JSON-RPC machinery as the supervise sidecar. The agent calls
-   the sidecar; it never sees the forge token or forge-specific endpoints.
-4. The sidecar is backed by a `Forge` abstract class. Gitea is the first
-   concrete implementation; adding a forge means a new subclass, not changes to
-   the agent prompt or sidecar protocol. The sidecar enforces a read-anywhere /
-   write-scoped model: writes are limited to the assigned issue and its PRs;
-   reads are unrestricted for context.
-5. The agent calls `signal_done(status, summary)` on the sidecar when a work
-   unit is complete; the sidecar relays it to the orchestrator over a queue dir.
-   This is the done signal — no comment parsing. A watchdog timeout
-   (configurable, default 30 min) causes the orchestrator to treat the run as
-   done-without-self-report if the agent exits without signalling.
-6. Every orchestrator-posted comment ends with a provenance footer: agent name,
-   bottle name(s), slug, start time, duration, exit code, gitleaks result, and
-   egress summary.
-7. Forge state (issue → slug, status) is persisted to disk and survives
-   orchestrator restarts.
-8. `./cli.py orchestrate status` lists active forge-managed bottles and their
-   issue/PR URLs.
-9. Unit tests cover: label parsing, org-membership check path, forge state
-   read/write, provenance footer rendering, headless launch arg construction,
-   forge env var injection, sidecar request dispatch through the `Forge`
-   abstraction, write-scope enforcement (reject writes outside the assigned
-   issue/PRs), and `signal_done` queue relay.
-
-## Non-goals
-
-- Webhook signature verification (HMAC-SHA256). Added as a follow-up.
-- The `bot-bottle-orchestrator` binary itself — this PRD covers bot-bottle's
-  side of the interface only. The orchestrator is a separate project.
-- GitHub or GitLab support.
-- Multiple simultaneous forge bottles per issue.
-- Automatic retry on agent error exit.
-- Bottle destruction on issue close (PR close only; issue close is ambiguous).
-- Concurrent multi-issue handling (one blocking run per orchestrator process).
-- A monitoring dashboard (orchestrator-side concern).
-- Folding `DeployKeyProvisioner` into the `Forge` abstraction. Deploy-key
-  provisioning runs at bottle-provision time on the host; the forge sidecar runs
-  inside the bottle at agent time. The two have different lifecycles and actors,
-  so coupling them into one class is deferred to a follow-up. This PRD only
-  shares the Gitea HTTP client between them.
-
-## Design
-
-### Targeting convention
-
-An issue is forge-targeted when **both** hold:
-
-- At least one assignee is a member of the Gitea org named by `FORGE_ORG`
-  (default `bot-bottle`). Checked via `GET /api/v1/orgs/{org}/members/{user}`.
-- At least one label has the prefix `bot-bottle:`. The suffix names the agent
-  manifest, e.g. `bot-bottle:implementer` → agent `implementer`.
-
-`FORGE_ORG` is read at orchestrate-command startup. It is not embedded in
-manifests or state files; the orchestrator stamps its value into log output for
-auditability.
-
-An optional label `bot-bottle-bottle:<name>` overrides bottle selection. When
-absent the agent's default bottle is used.
-
-### `./cli.py orchestrate` — the thin wrapper
-
-```
-./cli.py orchestrate start  --agent AGENT [--bottle BOTTLE ...] --prompt PROMPT
-                            [--label LABEL] [--backend BACKEND]
-./cli.py orchestrate resume --slug SLUG --prompt PROMPT [--backend BACKEND]
-./cli.py orchestrate status
-```
-
-`orchestrate start` is a thin shim over the already-shipped `start --headless`
-(#315): it forwards agent / bottle / label / prompt and adds the forge-specific
-wiring (`forge_env`, sidecar launch). It does not re-implement headless launch.
-The caller (`bot-bottle-orchestrator`) manages freeze, state, and the forge
-sidecar's done signal around it.
-
-`orchestrate resume` is the shim over the new `resume --headless` (below).
-
-`orchestrate status` prints the forge state table.
-
-### Headless primitives — what exists vs. what's new
-
-Headless **start** already shipped in #315 and this PRD reuses it as-is:
-
-- `./cli.py start <agent> --headless --prompt TEXT` — no TUI selectors, no y/N
-  preflight. Internally `_start_headless()` calls the shared `_launch_bottle()`
-  with `assume_yes=True` and `headless_prompt_text=prompt`.
-- The prompt is delivered through `AgentProvider.headless_prompt(prompt)` —
-  claude `-p`, codex positional, pi `-p`. The orchestrator does **not** hand-roll
-  agent args; it relies on this provider abstraction. (An earlier draft proposed
-  `start_headless` / `attach_agent_headless` helpers that constructed
-  `--no-interactive`/`-p` directly — those are dropped as redundant with, and
-  divergent from, what #315 merged.)
-
-Two additions are needed on top of #315:
-
-**1. A `forge_env` hook on the headless launch path.** The orchestrator needs to
-pass forge context + token through to the forge sidecar launched alongside the
-agent. This is a parameter threaded into `_launch_bottle` (the same core
-`start --headless` already uses), not a parallel launch function. The agent
-process itself does not receive the token.
-
-**2. `resume --headless`** — new in `bot_bottle/cli/resume.py`, mirroring the
-`--headless` flag on `start`:
-
-```
-./cli.py resume <slug> --headless --prompt TEXT
-```
-
-It rehydrates a frozen bottle and runs one headless prompt via the same
-`assume_yes` + `headless_prompt` path, returning the agent's exit code. `resume`
-has no non-interactive entry point today, so this is genuinely new work rather
-than a rename of an existing helper.
-
-### Forge sidecar
-
-Forge-targeted bottles run a forge sidecar alongside the agent, mirroring the
-supervise sidecar: a per-bottle process that exposes an HTTP/JSON-RPC endpoint
-over a Unix socket and relays events to the orchestrator through a queue dir.
-The agent calls the sidecar; the sidecar holds the forge token and makes the
-actual forge API calls. The agent never receives the credential and never sees a
-forge-specific endpoint — swapping Gitea for another forge does not change the
-agent prompt or the sidecar protocol.
-
-The sidecar is configured at launch from the forge context (owner, repo, issue,
-PR) and the token, supplied by the orchestrator — not baked into the agent
-manifest. Because the sidecar owns the token, forge traffic does not need a
-cred-proxy egress route on the agent; the agent's egress policy is unchanged by
-forge targeting.
-
-**Sidecar protocol** (forge-agnostic; each method maps to a `Forge` call):
-
-| Method | Scope | Purpose |
-|---|---|---|
-| `read_issue(number)` | read-anywhere | Read issue/PR body for context |
-| `read_comments(number)` | read-anywhere | Read a thread for context |
-| `post_comment(number, body)` | write-scoped | Post to the assigned issue/PR |
-| `update_description(number, body)` | write-scoped | Edit the assigned issue/PR body |
-| `signal_done(status, summary)` | — | Relay completion to the orchestrator |
-
-**Scope enforcement** is read-anywhere / write-scoped: read methods accept any
-issue/PR number for context; write methods are rejected unless the target is the
-assigned issue or one of its PRs. This is tighter than Gitea's repo-wide API-key
-permissions and bounds the blast radius of a prompt-injected agent. Rejections
-are logged semantically (operation, target, reason) so the audit trail records
-attempted out-of-scope writes, not just allowed ones.
-
-**Semantic audit**: every sidecar call is logged as a structured operation
-("read PR #318 description", "posted comment to #317", "signalled done:
-success") rather than as opaque HTTP bytes. This log feeds provenance directly,
-with no post-hoc egress-log parsing.
-
-### `Forge` abstraction — `bot_bottle/contrib/forge/`
-
-The sidecar dispatches to a `Forge` abstract class. Each provider implements the
-operations behind the sidecar protocol:
-
-```python
-class Forge(abc.ABC):
-    @abc.abstractmethod
-    def read_issue(self, number: int) -> Issue: ...
-    @abc.abstractmethod
-    def read_comments(self, number: int) -> list[Comment]: ...
-    @abc.abstractmethod
-    def post_comment(self, number: int, body: str) -> None: ...
-    @abc.abstractmethod
-    def update_description(self, number: int, body: str) -> None: ...
-    @abc.abstractmethod
-    def is_org_member(self, org: str, username: str) -> bool: ...
-    @abc.abstractmethod
-    def get_pr_for_issue(self, number: int) -> int | None: ...
-    @abc.abstractmethod
-    def is_pr_open(self, number: int) -> bool: ...
-```
-
-`GiteaForge` is the first and only concrete implementation in this PRD. It wraps
-the Gitea HTTP client (below). Adding GitHub or GitLab later is a new subclass;
-the sidecar, protocol, and agent prompt are untouched.
-
-> **Deferred:** `DeployKeyProvisioner` is *not* folded into `Forge` here.
-> Deploy-key provisioning runs on the host at provision time; the sidecar runs
-> in the bottle at agent time. They have different lifecycles and actors, so a
-> shared abstract base would couple two unrelated auth contexts. For now they
-> only share the Gitea HTTP client; a later PRD can revisit unification.
-
-### Forge env vars
-
-The orchestrator passes forge context to the **sidecar** (not the agent) at
-launch. The agent does not need owner/repo/issue env vars to construct API
-calls, since it only names issue/PR numbers to the sidecar:
-
-| Var | Example | Purpose |
-|---|---|---|
-| `FORGE_GITEA_API` | `https://gitea.dideric.is/api/v1` | Base URL the sidecar calls |
-| `FORGE_OWNER` | `didericis` | Repo owner |
-| `FORGE_REPO` | `bot-bottle` | Repo name |
-| `FORGE_ISSUE_NUMBER` | `317` | Assigned issue (defines write scope) |
-| `FORGE_PR_NUMBER` | `318` | Assigned PR (empty until PR exists) |
-
-The agent's forge-specific prompt instructs it to call `signal_done` on the
-sidecar when a work unit is complete, and to use the sidecar for any
-comment/description writes. The instruction is forge-agnostic and is part of the
-forge prompt overlay, not the base agent manifest, so non-forge runs are
-unaffected.
-
-### Done signal and watchdog
-
-The agent calls `signal_done(status, summary)` on the sidecar when it finishes a
-work unit. The sidecar writes the event to its queue dir; the orchestrator reads
-it and:
-
-1. Reads the forge state for `(owner, repo, issue_number)`.
-2. If `status == "running"`, treats the event as the done signal: freezes the
-   bottle, posts a summary comment with the provenance footer, sets
-   `status = "frozen"`.
-
-Because completion is an explicit `signal_done` call, the orchestrator does not
-parse comment text to detect "done", and intermediate comments the agent posts
-mid-run cannot be mistaken for completion.
-
-**Watchdog**: the orchestrator tracks `last_checkin_at` in forge state, updated
-on each sidecar event. A background thread wakes every minute. If
-`now - last_checkin_at > FORGE_WATCHDOG_TIMEOUT` (default 30 min, configurable
-via env) and `status == "running"`, the orchestrator treats the run as
-done-without-self-report: it posts the provenance footer (with `watchdog_fired`
-set) and freezes the bottle.
-
-**Sidecar-death failure mode**: if the forge sidecar crashes mid-run the agent
-loses forge access while the bottle is otherwise healthy. The orchestrator
-detects a dead sidecar (socket/queue gone) the same way it detects a stalled
-agent and falls back to the watchdog path, posting a footer that flags the
-incomplete run.
-

-
-The egress summary is read from `~/.bot-bottle/state/<slug>/egress/`. When

-
-### Gitea HTTP client — `bot_bottle/contrib/gitea/client.py`
-
-`GiteaForge` (and the existing `GiteaDeployKeyProvisioner`) share one thin HTTP
-client. Unlike the option-2 design, the token is held by the sidecar process and
-passed to the client directly — there is no agent-side cred-proxy route to
-inject it, because the agent never makes forge calls.
-
-```python
-class GiteaClient:
-    def __init__(self, *, api_url: str, owner: str, repo: str, token: str) -> None: ...
-    def is_org_member(self, org: str, username: str) -> bool: ...
-    def post_comment(self, issue_number: int, body: str) -> None: ...
-    def update_comment_body(self, issue_number: int, body: str) -> None: ...
-    def get_pr_for_issue(self, issue_number: int) -> int | None: ...
-    def is_pr_open(self, pr_number: int) -> bool: ...
-```
-
-Sharing only the HTTP client (not an abstract base) is the deliberate boundary
-between the sidecar and the deploy-key provisioner — see the deferral note under
-the `Forge` abstraction.
-
-### Implementation chunks
-
-1. **Headless additions on top of #315** — thread a `forge_env` parameter into
-   the existing `_launch_bottle` core (the one `start --headless` already uses);
-   add a `--headless` path to `cli/resume.py` reusing `assume_yes` +
-   `headless_prompt`. No new `start_headless`/`attach_agent_headless` helpers.
-   Tests: `forge_env` reaches the sidecar/`guest_env`; `resume --headless` skips
-   the TUI and y/N preflight and returns the agent exit code.
-
-2. **Forge state** — `contrib/gitea/forge_state.py`: `ForgeState` dataclass,
-   read/write/delete/all helpers, atomic rename. Tests: round-trip JSON, missing
-   file → None, atomic write.
-
-3. **`Forge` abstraction + Gitea client** — `contrib/forge/base.py` (`Forge`
-   ABC) and `contrib/gitea/client.py` + `GiteaForge`: `is_org_member`,
-   `read_issue`, `read_comments`, `post_comment`, `update_description`,
-   `get_pr_for_issue`, `is_pr_open`. Tests: mock `urllib.request.urlopen`,
-   assert payloads and 404-as-false for membership.
-
-4. **Forge sidecar** — sidecar process exposing the protocol over a Unix socket,
-   queue-dir relay, write-scope enforcement, semantic op log, `signal_done`.
-   Reuses the supervise sidecar bundle machinery. Tests: dispatch each method to
-   the `Forge`, reject out-of-scope writes, `signal_done` writes a queue event,
-   scope-rejection is logged.
-
-5. **Provenance** — `contrib/gitea/provenance.py`: `build_provenance_footer`.
-   Tests: required fields present, watchdog row text, egress omitted when log
-   absent.
-
-6. **`./cli.py orchestrate`** — `cli/orchestrate.py` with `start`, `resume`,
-   `status` subcommands wired into `cli.py`; `start` launches the forge sidecar
-   alongside the agent for forge-targeted runs. Tests: arg parsing, `start`
-   delegates to `start --headless`, `resume` delegates to `resume --headless`.
-
-## Provenance as the product
-
-Every orchestrator-posted comment ends with the provenance footer — non-optional
-and not configurable off. PRs that land without a footer were not produced by
-this integration. The `watchdog_fired` flag in the footer flags runs where the
-agent did not self-report completion, so reviewers know the audit trail may be
-incomplete.
-
-The footer links to the bot-bottle repo pinned to the commit SHA active during
-the run (not `main`), so the policy that governed the run is permanently
-anchored in the PR history.

+# 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

-"""Unit: EgressAddon request/response decision flow (issue #286).
-
-`egress_addon.py` is the sidecar-only mitmproxy adapter that wires the
-host-importable decision logic in `egress_addon_core` into mitmproxy's
-request/response hooks. The core logic is exercised directly by
-`test_egress_addon_core.py`; the redaction logging by
-`test_egress_addon_log_redaction.py`. This file covers the adapter glue
-itself — `request()`, `response()`, `websocket_message()`, introspection,
-auth injection, git push/fetch blocking and the outbound-DLP policy
-branches — so `bot_bottle/egress_addon.py` no longer has to be omitted
-from coverage.
-
-mitmproxy is not installed on the host, so we pre-populate `sys.modules`
-with the minimum stubs needed to import the adapter (a `mitmproxy.http`
-module exposing a `Response` with `.make`, plus the flat
-`egress_addon_core` name the sidecar uses)."""
