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.

+On compatible macOS hosts, the default backend requires Apple's `container` CLI and does not require 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 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`.
 ```sh
 ./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.

 # 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. 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.
 Run provenance is exposed through a **provenance API** (the sidecar's structured
 operation log plus the run's metadata), not posted back into the forge. We do
 not surface a provenance footer in the PR — the audit record lives behind the
 API where it can be retained and queried, rather than as an editable comment.
 The separation of concerns across the two layers: bot-bottle owns the headless
 launch primitives, the forge sidecar + `Forge` abstraction, and forge state.
 `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. Run provenance (agent name, bottle name(s), slug, timing, exit code,
   gitleaks result, egress summary, and the sidecar's semantic operation log)
   is available through a provenance API. It is **not** surfaced as a PR footer
   or any other forge comment.
 7. Forge state (issue → slug, status) is persisted in a local SQLite database
   under `~/.bot-bottle/` 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
   store CRUD (SQLite), 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 an issue body for context |
 | `read_pr(number)` | read-anywhere | Read a PR (incl. merge state) 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 |
 Issues and PRs are distinct domain objects (`Issue` vs `PullRequest`) read
 through distinct methods; a PR carries merge state an issue does not.
 **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

 `Issue` and `PullRequest` are separate frozen dataclasses — a PR adds `merged`.
 `ScopedForge` wraps a concrete `Forge` to enforce the read-anywhere /
 write-scoped model (`post_comment` / `update_description` raise `ForgeScopeError`
 outside the assigned issue and PRs).
 `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.

 ### 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 and sets `status = "frozen"`. Provenance is recorded via the
   provenance API — no comment is posted to the forge.
 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 and freezes the bottle, flagging the run as incomplete
 in the provenance record.
 **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.
 ### Forge state — `bot_bottle/contrib/gitea/forge_state.py`
 State is stored in a local SQLite database at `~/.bot-bottle/bot-bottle.db`.
 Access goes through a thin CRUD interface, `ForgeStateStore`, so the storage
 location/engine can be swapped without touching callers. `SqliteForgeStateStore`
 is the first implementation.
 The `forge_state` table is keyed by `(owner, repo, issue_number)` and carries:
 `slug`, `agent_name`, `bottle_names` (JSON), `backend_name`, `agent_git_user`,
 `pr_number` (nullable), `status`, `last_checkin_at`.
 `status`: `"running"` | `"frozen"` | `"destroyed"`.
 Store interface:
 ```python
 class ForgeStateStore(abc.ABC):
    def upsert(self, state: ForgeState) -> None: ...
    def get(self, owner: str, repo: str, issue_number: int) -> ForgeState | None: ...
    def delete(self, owner: str, repo: str, issue_number: int) -> None: ...
    def all(self) -> list[ForgeState]: ...
 class SqliteForgeStateStore(ForgeStateStore):
    def __init__(self, db_path: Path | None = None) -> None: ...
 ```
 `upsert` uses `INSERT OR REPLACE` so a re-run for the same issue overwrites in
 place. The schema is created on first open.
 ### Provenance API
 Run provenance — agent, bottle(s), slug, timing, exit code, gitleaks result,
 egress summary, watchdog-fired flag, and the sidecar's semantic operation log —
 is exposed through a **provenance API**, not posted into the forge. There is no
 provenance footer or run-summary comment.
 The rationale (per the monetization positioning): a PR comment is mutable by any
 maintainer, unsigned, and per-PR, so it is worthless as an audit record and
 invites false trust. The authoritative record therefore lives behind the API,
 where it can be retained, queried, and (eventually) signed. Whether any
 projection of it ever appears in the forge is a separate, out-of-scope decision;
 this PR does not build one.
 The API surface itself (schema, transport, signing, retention) is **out of scope
 for this PRD** and belongs with the orchestrator / control-plane work. bot-bottle
 here only produces the raw material: the sidecar's semantic operation log and the
 run metadata the orchestrator collects.
 ### 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 get_issue(self, number: int) -> dict: ...
    def get_comments(self, number: int) -> list[dict]: ...
    def post_comment(self, number: int, body: str) -> None: ...
    def patch_issue_body(self, number: int, body: str) -> None: ...
    def get_pull(self, number: int) -> dict: ...
 ```
 `GiteaForge` adapts this client to the `Forge` surface (mapping raw JSON to
 `Issue` / `PullRequest` / `Comment`). 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,
   `ForgeStateStore` CRUD interface, `SqliteForgeStateStore`. Tests: round-trip,
   missing → None, `INSERT OR REPLACE` upsert, delete idempotent, `all()`
   ordering, persistence across store instances.
 3. **`Forge` abstraction + Gitea client** — `contrib/forge/base.py` (`Forge`
   ABC, `ScopedForge`, `Issue` / `PullRequest` / `Comment`) and
   `contrib/gitea/client.py` + `GiteaForge`: `is_org_member`, `read_issue`,
   `read_pr`, `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; `ScopedForge` write-scope
   enforcement.
 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. **`./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
 Run provenance is captured (sidecar semantic operation log + run metadata) and
 exposed through a provenance API. It is deliberately **not** surfaced in the
 forge — no footer, no run-summary comment. A mutable, unsigned PR comment is not
 an audit record; the authoritative record lives behind the API where it can be
 retained and signed. The `watchdog_fired` flag marks runs where the agent did
 not self-report completion so consumers of the API know the record may be
 incomplete.
 The provenance API's schema, transport, signing, and retention are out of scope
 for this PRD (control-plane work); bot-bottle here produces the raw material
 only.

 # 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).

 Individual tests that need their own ``HOME`` still override
 ``os.environ['HOME']`` and restore it; they now restore to this isolated

 """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)."""
