test: update PipelockRoutePolicy tests for Config dict design

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

+  short-description: Score code quality with a strict rubric
+---
+
+# Quality Eval
+
+## Role
+
+Act as a Staff Software Engineer and automated quality gate. Evaluate code objectively against the rubric below, surface hidden anti-patterns, and provide a mathematical grade with atomic refactoring steps.
+
+## Evaluation Rules
+
+- Evaluate only against the five rubric dimensions.
+- Be candid. Do not inflate scores for politeness.
+- Avoid generic advice. Every recommendation must name a specific code location, behavior, or pattern and include a concrete improvement direction.
+- Inspect the code before scoring. For codebases, read enough representative files, tests, and architecture boundaries to justify the scope.
+- When exact line numbers are available, cite them.
+- Do not reveal private chain-of-thought. In the required `Chain of Thought Analysis` section, provide a concise, step-by-step audit rationale with observable findings and score justifications.
+
+## Rubric
+
+Score each dimension from 1 to 5 using these anchors:
+
+| Dimension | Score 1 (Fail) | Score 3 (Pass) | Score 5 (Exemplary) |
+| :--- | :--- | :--- | :--- |
+| **Architecture** | Spaghettified; tight coupling; violated separation of concerns. | Modular but relies on leaky abstractions or mixed domains. | Strict domain isolation; follows SOLID; clear dependency inversion. |
+| **Readability** | Cryptic naming; deep nesting (>3 levels); widespread DRY violations. | Idiomatic but features over-complex functions or sparse documentation. | Self-documenting; expressive naming; high cohesion; flat structure. |
+| **Resilience** | Swallows errors blindly; lacks contextual logging; fragile to bad input. | Basic try/catch blocks present but lacks granular, typed error handling. | Explicit error boundaries; contextual logging; structured failure modes. |
+| **Testability** | Hardcoded dependencies make mocking or isolated testing impossible. | Pure functions are testable, but side-effect heavy logic lacks test hooks. | Decoupled IO; deterministic execution; structured for unit and integration tests. |
+| **SecOps** | Hardcoded secrets; O(n^2) bottlenecks; zero input sanitization. | Safe from obvious flaws but lacks deep defensive optimization. | Validated inputs; optimized algorithmic complexity; zero security debt. |
+
+## Scoring Method
+
+1. Determine the evaluated scope and primary language.
+2. Identify concrete evidence for each dimension.
+3. Assign integer dimension scores from 1 to 5.
+4. Compute `composite_score` as the arithmetic mean of the five dimension scores, rounded to one decimal place.
+5. Include code snippets only when they make a refactoring step more actionable.
+
+## Required Output
+
+Structure every response into exactly these three Markdown sections:
+
+### 1. Chain of Thought Analysis
+
+Provide a concise step-by-step audit rationale. Name specific files, functions, patterns, anti-patterns, and rubric anchors. Keep it evidence-based and do not include hidden private reasoning.
+
+### 2. Normalized Score Report
+
+```json
+{
+  "evaluation_metadata": {
+    "target_scope": "string",
+    "primary_language": "string"
+  },
+  "metrics": {
+    "architecture_and_modularity": 0,
+    "readability_and_maintainability": 0,
+    "error_handling_and_resilience": 0,
+    "testability_and_mocking": 0,
+    "security_and_performance": 0
+  },
+  "composite_score": 0.0
+}
+```
+
+### 3. Atomic Refactoring Playbook
+
+* **High Priority (To lift Score 1/2 to 3):**
+  - [ ] Actionable, specific refactoring step with file/line/context reference.
+* **Medium Priority (To lift Score 3 to 4/5):**
+  - [ ] Optimization or architectural pattern implementation step.

+
+## What this is
+
+bot-bottle spins up an isolated container for running AI coding agents with a
+curated set of skills and env vars. The point is to run agents with broad
+permissions inside a sandbox, so a misbehaving agent cannot reach the host.
+A Python CLI (entry point `cli.py`, package `bot_bottle/`) orchestrates
+the container lifecycle and the copying of skills and env vars into it.
+
+## Goals
+
+- Minimize risk of running agents with full permissions
+- Allow me to easily spin up agent tasks in parallel
+- Create isolated, well defined, easily updated, shareable agents
+
+## Non-goals
+
+- Communicating between agents directly
+- Self hosted VMs (v1 uses local Docker containers, not VMs)
+- Advanced agent auditing (lean on git history for auditing)
+
+## Repository layout
+
+- `README.md` — short public-facing description.
+- `AGENTS.md` — this file, orientation for future agent sessions.
+- `.gitignore` — OS junk.
+- `bot-bottle.json` — legacy manifest of named agents (env / skills / prompt
+  per agent), consumed by `cli.py`. See "Manifest" under
+  "Intended design".
+- `docs/README.md` — docs overview; when to write which document.
+- `docs/prds/` — product requirement docs (see `docs/prds/README.md` for format).
+- `docs/research/` — research notes (see `docs/research/README.md`).
+- `docs/decisions/` — decision records (ADR-lite).
+
+## Conventions
+
+- Three kinds of doc, each with its own conventions in-folder; see
+  `docs/README.md` for when to write which:
+  - **PRDs** (`docs/prds/`) — one feature per file, numbered
+    `NNNN-kebab.md`. A `Status:` line tracks lifecycle: Draft → Active
+    (shipped to `main`) → Superseded/Retargeted. Format in
+    `docs/prds/README.md`.
+  - **Research notes** (`docs/research/`) — opinionated investigations;
+    unnumbered kebab-case, freeform and verdict-first. See
+    `docs/research/README.md`.
+  - **Decision records** (`docs/decisions/`) — ADR-lite, numbered
+    `NNNN-kebab.md`, for policies and non-feature decisions. See
+    `docs/decisions/README.md`.
+- Keep decision rationale self-contained in the repo, not in Gitea
+  issue threads. Issues are an ephemeral inbox; the durable "why" lives
+  in a PRD, research note, or decision record.
+- Low dependencies by default. The project is Python, stdlib-first (no
+  runtime pip dependencies in the package itself; the only language
+  runtime is the Python 3.13 used by the CLI + sidecars). Ask before
+  adding new tools, runtimes, or package managers.
+- Commit messages follow [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/):
+  `<type>[(scope)][!]: <description>`, where `<type>` is one of `feat`, `fix`,
+  `docs`, `style`, `refactor`, `perf`, `test`, `build`, `ci`, `chore`, `revert`.
+  A `commit-msg` hook in `.githooks/` enforces this. Activate it once per clone
+  with `git config core.hooksPath .githooks`.

-Run multiple Claude Code agents on your own machine, each scoped to its own secrets, skills, and egress allowlist.
+**Problem:** Developer wants to run a coding agent without supervision, but they don't want a prompt injected or misbehaving agent wrecking their environment or exfiltrating sensitive data.
 
-![pipelock and git-gate blocking exfil attempts against a live bottle](docs/demo.gif)
+**Solution:** Ephemeral, per agent "bottles" the agent cannot modify that scan all traffic for data exfiltration and limit capabilities and egress to only what the agent needs.
 
-Four prompts to the agent inside a real bottle:
-claude replies to `hello there` — proof api.anthropic.com routes
-through pipelock's bumped TLS end-to-end;
-asked to GET a non-allowlisted host, the agent's curl gets 403 back
-from pipelock;
-asked to POST a credential-shaped body to an allowlisted host, the
-same 403 — pipelock's DLP body scanner caught it;
-asked to commit and push an AKIA-shaped key, git-gate's gitleaks
-pre-receive hook rejects the ref.
-Run it yourself with `bash scripts/demo.sh`.
+## Features
 
-## Why "claude-bottle"?
-
-Each container is a bottle; Claude is the genie inside. The genie's
-powers are exactly what the manifest grants it — a specific set of
-skills, a specific set of secrets, and a specific set of hosts it can
-reach — nothing more. You uncork one bottle per agent
-(`./cli.py start <agent>`), many bottles run in parallel, and each is
-scoped to its task. When the session ends the bottle is destroyed and
-the genie does not persist.
-
-## Goals
-
-- Scope each agent to the minimum credentials and network egress its task actually needs
-- Run multiple agents in parallel, isolated from each other
-- Keep code, credentials, and agent activity on infrastructure I control — no third-party agent runtime
-
-## Security model
-
-Each agent runs in its own bottle: its own container, its own internal
-Docker network, and its own pipelock sidecar. Bottles don't share
-state, don't talk to each other, and only get the env vars, skills,
-SSH identities, and egress hosts the manifest grants them — nothing
-more. Any one agent only has the access it needs to do its job.
-
-The bottle limits both what an agent can see and where it can send
-it. Each bottle gets only the secrets and SSH identities the manifest
-grants it — a Gitea token but not a GitHub token, a deploy key but
-not a personal SSH key — so even a compromised or misbehaving agent
-only handles credentials it was already trusted with for its job.
-Egress flows through pipelock, which constrains where those
-credentials can travel: an agent with a Gitea token can reach
-`gitea.dideric.is`, not arbitrary attacker-controlled hosts. The same
-constraint blocks DNS-over-HTTPS as an exfil channel — a DoH resolver
-like `cloudflare-dns.com` would have to be on the allowlist for the
-agent to reach it at all. The container itself adds a layer between
-the agent and the host, but the v1 design leans more on secret
-minimization and egress allowlisting than on the container as a
-hardened boundary. On Linux hosts where [gVisor](https://gvisor.dev/)
-is registered with Docker, claude-bottle auto-detects it and launches
-every bottle under `runsc` for a userspace syscall barrier — no
-manifest configuration required. The broader v2 discussion lives in
-`docs/research/stronger-isolation-alternatives.md`.
-
-The egress proxy and OAuth-token handling below are the load-bearing
-pieces of v1.
+- **Per-bottle egress allowlist** — TLS-bumped HTTP/HTTPS chokepoint with a per-manifest host allowlist and request-body DLP scanner; DoH and arbitrary hosts blocked by default.
+- **Tokens the agent never sees** — host secrets live in a sidecar; the agent dials `http://sidecar:9099/<path>` and the proxy strips inbound `Authorization` and injects the real token before forwarding. `printenv` in the agent shows proxy URLs only.
+- **Gitleaks-scanned push (git-gate)** — `bottle.git` remotes route through a per-bottle `git daemon` that gitleaks-scans incoming refs pre-receive and forwards clean refs upstream over SSH. The agent never holds the upstream credential.
+- **Manifest-scoped skills + secrets** — each bottle declares its skills, env, git identity, remotes, and egress routes; unknown keys die at load.
+- **Trust boundary at `$HOME`** — bottles (credentials, egress, remotes) live only under `~/.bot-bottle/bottles/`. Repos may ship agents but not bottles, so a cloned repo can't redirect an env var to an attacker host.
+- **Composable bottles (`extends:`)** — keep provider/runtime policy in one base bottle (e.g. `claude.md`) and overlay task bottles on top.
+- **Parallel, isolated bottles** — each bottle is its own per-agent Docker `--internal` network; bottles don't share state or talk to each other.
+- **Provider templates (Claude, Codex)** — `Dockerfile.claude` / `Dockerfile.codex`, or a bottle-supplied Dockerfile. Claude auth via long-lived OAuth token; Codex via opt-in host device-auth forwarding.
+- **gVisor auto-detect** — on Linux hosts where `runsc` is registered with Docker, every bottle launches under it for a userspace syscall barrier; no manifest config required.
+- **Smolmachines backend (macOS)** — opt-in `BOT_BOTTLE_BACKEND=smolmachines` runs the agent in a libkrun micro-VM with the sidecar bundle still in Docker.
 
 ## Architecture
 
-A bottle is the agent container plus up to three per-protocol egress
-sidecars on a per-agent Docker `--internal` network. The agent has no
-default route off-box. All HTTP and HTTPS egress — from the agent
-*and* from cred-proxy when it dials an upstream — funnels through
-pipelock, where the egress allowlist, TLS interception, and
-request-body DLP scanner enforce the manifest before any byte leaves
-the host. The only egress that doesn't traverse pipelock is git-gate's
-SSH push/fetch to `bottle.git` upstreams — pipelock can't proxy SSH,
-so git-gate is its own L4-style egress path with gitleaks doing the
-pre-receive scan.
+A bottle is two containers per agent: an `agent` container, and a `sidecars` container that bundles pipelock + cred-proxy + git-gate + supervise behind a Python init supervisor. They share a per-agent Docker `--internal` network; the agent has no default route off-box.

-  base) on first run; runs `claude` with the manifest-granted skills,
-  env vars, and `~/.gitconfig` (the latter for the git-gate's
-  `insteadOf` rules when `bottle.git` is set).
-- **pipelock image** — per-agent sidecar. Terminates the agent's
-  outbound HTTP/HTTPS, enforces the resolved allowlist, runs DLP
-  scanning. Design in `docs/prds/0001-per-agent-egress-proxy-via-pipelock.md`
-  and `docs/prds/0006-pipelock-tls-interception.md`.
-- **git-gate image** — per-agent sidecar built on `zricethezav/gitleaks`
-  (alpine + gitleaks + git-daemon + openssh-client). Runs
-  `git daemon` over `git://` as a bidirectional mirror of each
-  declared upstream. A pre-receive hook gitleaks-scans incoming
-  refs and forwards clean refs to the real upstream over SSH; an
-  access-hook runs `git fetch origin --prune` against the upstream
-  before every upload-pack so an agent fetch returns whatever the
-  upstream has *now* (fail-closed if unreachable). The agent's
-  `~/.gitconfig` rewrites the real URL to the gate via `insteadOf`,
-  so push, fetch, clone, and pull all route through. The agent
-  never sees the upstream credential. If the upstream's hostname
-  isn't resolvable from the gate container (e.g. a Tailscale-only
-  host whose public DNS points elsewhere), pin its IP via
-  `ExtraHosts: { "<hostname>": "<ip>" }` on the `bottle.git` entry —
-  the gate's `/etc/hosts` gets the override while the agent's
-  `insteadOf` rewrite still keys off the original hostname. Brought
-  up only when `bottle.git` has entries. Design in
-  `docs/prds/0008-git-gate.md`.
-- **cred-proxy image** — per-bottle sidecar (`python:3.13-alpine`
-  base, stdlib-only) that holds API tokens declared in
-  `bottle.cred_proxy.routes`. Each route names a `path`,
-  `upstream`, `auth_scheme`, and `token_ref` (host env var); the
-  agent dials `http://cred-proxy:9099<path>...` over plain HTTP
-  and the proxy strips any inbound `Authorization`, injects
-  `<auth_scheme> <token>` using the value held only in its own
-  container's environ, and forwards to the real upstream over
-  HTTPS. SSE responses stream back unbuffered. The cred-proxy's
-  outbound HTTPS routes through pipelock (it trusts pipelock's
-  per-bottle CA), so pipelock's egress allowlist + body scanner
-  apply to cred-proxy traffic the same way they apply to direct
-  agent traffic. Smart-HTTP push paths (`/git-receive-pack`,
-  `/info/refs?service=git-receive-pack`) are refused at the
-  proxy — push must go through `bottle.git` / git-gate where
-  gitleaks runs. Optional per-route `role` tags drive agent-side
-  rewrites: `anthropic-base-url`, `npm-registry`, `git-insteadof`,
-  `tea-login`. The agent's `printenv` shows only proxy URLs —
-  none of the real token values. Design in
-  `docs/prds/0010-cred-proxy.md`.

-is one file in `agents/`:
+Bottles and agents are Markdown files with YAML frontmatter under `~/.bot-bottle/`. The Markdown body is the system prompt. Bottles live in `~/.bot-bottle/bottles/`; agents may also be shipped by a repo at `<repo>/.bot-bottle/agents/<name>.md`.

-A repo can ship its own agent files alongside its code at

-— credentials, egress allowlists, git remotes — comes from your home
-directory only. A cloned repo cannot redirect a host env var to an
-attacker-named upstream because it has no way to declare a bottle.

-ambiguous bare strings (`yes` / `NO` / `2026-05-24` /

-strings when in doubt. The full schema lives in

-## Auth: OAuth token, not API key
-
-claude-bottle authenticates `claude` inside the container with the same
-Pro/Max subscription you already use on the host, via a long-lived OAuth
-token. No `ANTHROPIC_API_KEY` is needed.
-
-**Why a token instead of mounting `~/.claude.json`:** on macOS, Claude
-Code stores OAuth credentials in the encrypted Keychain, not in
-`~/.claude.json`. Mounting that file into a Linux container does not
-carry the credentials with it. Linux hosts keep credentials in
-`~/.claude/.credentials.json`, but to keep the launcher portable
-claude-bottle uses the env-var path on every host.
-
-**One-time setup on the host:**
-
-```sh
-claude setup-token   # browser login, prints a ~1-year OAuth token
-```
-
-Stash the token in your shell env (e.g. `~/.zshrc` or a secret manager)
-as `CLAUDE_BOTTLE_OAUTH_TOKEN`:
-
-```sh
-export CLAUDE_BOTTLE_OAUTH_TOKEN="<token>"
-```
-
-The bottle reaches the Anthropic API only through the cred-proxy
-sidecar. To let `claude` authenticate, declare a route in
-`bottle.cred_proxy.routes` with `role: "anthropic-base-url"` and
-`token_ref: "CLAUDE_BOTTLE_OAUTH_TOKEN"`:
-
-```jsonc
-{
-  "path":        "/anthropic/",
-  "upstream":    "https://api.anthropic.com",
-  "auth_scheme": "Bearer",
-  "token_ref":   "CLAUDE_BOTTLE_OAUTH_TOKEN",
-  "role":        "anthropic-base-url"
-}
-```
-
-At launch, `cli.py` reads `CLAUDE_BOTTLE_OAUTH_TOKEN` from the host
-env and forwards it into the cred-proxy container's environ — never
-into the agent's. The agent receives `ANTHROPIC_BASE_URL` pointing at
-`http://cred-proxy:9099/anthropic` and a non-secret placeholder for
-`CLAUDE_CODE_OAUTH_TOKEN` (claude-code refuses to start without one;
-the proxy strips and replaces the header on every request). `printenv`
-inside the agent does not surface the real token, and the value is
-never written to disk or placed on argv on the host.
-
-A bottle without an `anthropic-base-url` route has no path to the
-Anthropic API — there is no fallback that forwards the token directly
-to the agent. Caveats: the token is bound to your subscription tier
-(Pro/Max/Team/Enterprise), it does not work with `claude --bare`
-(which only reads `ANTHROPIC_API_KEY`), and if it leaks, regenerate
-via `claude setup-token` again. Reference:
-<https://code.claude.com/docs/en/authentication>.

+
+Post-PRD-0017 the CA depends on the agent's HTTP_PROXY target:
+
+  - Bottle declares `egress.routes[]` → agent's HTTP_PROXY
+    points at egress; the cert the agent must trust is the
+    one egress mints leaf certs with (the egress CA).
+  - No egress routes → agent's HTTP_PROXY points straight at
+    pipelock; the cert the agent must trust is pipelock's CA (the
+    pre-cutover behavior).
+
+By the time this provisioner runs, the corresponding `tls_init`
+helper has generated the chosen CA under `plan.stage_dir`, and the
+sidecar (pipelock or egress) is up referencing the
+in-container CA paths.
+
+Cert lands on Debian's standard source path
+(`/usr/local/share/ca-certificates/`); `update-ca-certificates`
+rebuilds `/etc/ssl/certs/ca-certificates.crt`, which is what curl,
+Python `ssl`, and OpenSSL-based tools all read by default. The env
+trio set on the agent's `docker run` covers Node
+(`NODE_EXTRA_CA_CERTS`) and Python `requests` /
+`SSL_CERT_FILE`-honoring libraries that don't load the system
+bundle.
+
+The fingerprint is computed via stdlib (`ssl.PEM_cert_to_DER_cert`
++ `hashlib.sha256`) and logged once to stderr. The private key
+stays on the host (under `stage_dir`) until teardown wipes the
+stage dir; nothing in the agent ever sees it."""

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

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

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

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

+Failure policy (eventual): on unexpected death, the supervisor

+PR; the interim policy is "don't take the bundle down for one
+sick daemon."
