 ## Architecture
 
-On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a gateway attached to both that internal network and a NAT egress network. The agent gets HTTP(S)_PROXY and CA bundle env vars pointing at the gateway's internal-network IP, so HTTP/HTTPS traffic flows through the gateway instead of direct egress. `bottle.git` / git-gate is intentionally deferred on this backend until a safe Apple Container key-delivery path exists.
+On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a gateway attached to both that internal network and a NAT egress network. The agent gets HTTP(S)_PROXY and CA bundle env vars pointing at the gateway's internal-network IP, so HTTP/HTTPS traffic flows through the gateway instead of direct egress. git-gate runs over the gateway's consolidated `git-http` daemon (the legacy per-bottle `git://` daemon is not used on this backend); keys are provisioned dynamically at launch and revoked on teardown.
 
 On the Firecracker backend, a bottle is an agent microVM plus a Docker gateway for egress, git-gate, and supervise. The VM reaches the gateway over a per-bottle point-to-point TAP link; a dedicated fail-closed `nftables` table (`inet bot_bottle_fc`) confines the guest to that link, so nothing leaves the box except through the gateway. The TAP pool and nft table are provisioned once (root); per-launch needs no privilege.

 Use `BOT_BOTTLE_BACKEND=docker ./cli.py start <agent>` on hosts where neither Apple Container nor KVM is available and Docker is the desired backend.
 
+> **CI (macOS Apple Container):** the `integration-macos` job (`.gitea/workflows/test.yml`) runs the integration suite against `BOT_BOTTLE_BACKEND=macos-container` on a self-hosted macOS runner labelled `macos`, because Apple Container needs the host virtualization framework and cannot run in a Linux container (so it can't reuse the `kvm` runner). Provision an Apple Silicon host with the `container` CLI on `PATH` and `container system status` running, then register the runner in **host mode** (not docker mode) with the `macos` label — `brew install gitea-runner` (the `act_runner` rename). Give it a Python ≥ 3.11 with `coverage` importable on the launchd service's `PATH` (a launchd service doesn't inherit your shell profile, so pin `node` and the Python env explicitly). The job is **advisory** — `workflow_dispatch` (manual) only, never triggered by push or PR — since a single laptop that sleeps/roams must not block merges or churn on every push to main; its coverage doesn't feed the gate. The infra container is a singleton (`bot-bottle-mac-infra`), so keep runner concurrency at 1.

+The gateway / infra / orchestrator images are built from a Docker (or Apple

+`pyproject.toml`, and the root-level Dockerfiles as siblings. In a source
+checkout that context is simply the repo root, one level above the package.

+
+``build_root()`` is the single source of truth — it returns a directory laid
+out like a repo root (has ``bot_bottle/``, ``pyproject.toml``, the
+Dockerfiles, ``nix/``, ``scripts/``). Every caller that needs a build
+context, a Dockerfile path, the nix netpool module, or the netpool script
+derives from it, so checkout and wheel installs share one downstream path.

+
+- **Status:** Active
+- **Author:** Claude
+- **Created:** 2026-07-25
+- **Issue:** #426
+
+## Summary
+
+CI has no runner for the `macos-container` (Apple Container) backend.
+`.gitea/workflows/test.yml` exercises Docker (`ubuntu-latest`) and
+Firecracker (self-hosted `kvm`) but never the macOS backend. This PRD adds a
+self-hosted macOS runner (label `macos`) and an advisory `integration-macos`
+job that runs the integration suite against `BOT_BOTTLE_BACKEND=macos-container`,
+so the backend that is the default on macOS stops shipping unexercised.
+
+## Problem
+
+The gap is not theoretical. `5ad3449` moved `bot_bottle` from flat files under
+`/app` into a pip-installed package but left init scripts spawning the
+supervisor as `python3 /app/gateway_init.py`, which no longer exists. Both the
+Firecracker and macOS backends carried the identical bug:
+
+- **firecracker** — caught and fixed in `127ba49` because the KVM runner
+  (added in `c193b04`, PR #349) runs that backend's integration suite.
+- **macos-container** — survived on `main` and only surfaced when a human ran
+  `bot-bottle start` by hand.
+
+The failure mode is expensive to debug: the supervisor never starts, so
+mitmdump never generates its CA, and launch dies downstream with
+`GatewayError: gateway CA not available`, which points at TLS rather than at
+the supervisor. Unit tests did not help — `test_macos_infra` asserted the
+substring `"gateway_init.py"`, which the *broken* path satisfies. (That
+specific assertion has since been tightened to the module form
+`bot_bottle.gateway_init`, matching its Firecracker twin, so the exact
+regression is now covered on `ubuntu-latest`. What remains missing is the
+end-to-end runner that would catch the *next* macOS-only launch regression.)
+
+PR #470 (#414) already made the integration suite backend-agnostic:
+`skip_unless_selected_backend_available()` gates on the *selected* backend's
+own `is_backend_ready()` rather than `docker_available()`, and each
+integration job runs `./cli.py backend status --backend=<name>` as a preflight
+that fails loudly when the backend is missing. That is the machinery this job
+plugs into; this PRD supplies the runner and the job.
+
+## Goals / Success criteria
+
+- A macOS runner is registered and picks up jobs by the `macos` label.
+- An `integration-macos` job runs the integration suite against
+  `BOT_BOTTLE_BACKEND=macos-container`.
+- The job **fails, not skips**, when the backend is unavailable on the runner
+  (via the `backend status` preflight).
+- Reverting the `macos_container/infra.py` supervisor fix makes the job fail:
+  the broken supervisor path throws `GatewayError` at bottle launch, which is
+  `TestSandboxEscape.setUpClass`, failing the whole class before any individual
+  attack runs.
+
+## Non-goals
+
+- Making `integration-macos` a **required** PR check. It runs on
+  `workflow_dispatch` (manual dispatch) only — never on push or PRs. A single
+  non-redundant laptop that sleeps and roams must never be able to block a PR
+  merge or churn unattended on every push to main, and it is deliberately kept
+  out of the `coverage` job's `needs` so the diff-coverage gate never depends on
+  it.
+- Multi-machine or hosted macOS runners. Apple Container needs the host
+  virtualization framework, so the runner must be a physical/VM macOS host on
+  Apple Silicon — it cannot reuse the KVM runner or run in a Linux container.
+- Coverage aggregation from the macOS job into the combined gate (would couple
+  the gate to the laptop).
+
+## Design
+
+### Runner (operational, provisioned once)
+
+- Apple Silicon macOS host with Apple's `container` CLI installed and
+  `container system status` reporting `running`.
+- Install the runner: `brew install gitea-runner` (the `act_runner` rename),
+  registered in **host mode** with label `macos` — not docker mode, because
+  Apple Container needs the host `container` CLI and virtualization framework,
+  not a nested container.
+- A Python ≥ 3.11 with `coverage` importable on the runner's `PATH`. Because a
+  launchd service does not inherit an interactive shell's `PATH`, pin `node`
+  (for the JS `actions/*`) and the Python env explicitly in the service
+  environment rather than relying on `nvm`/shell profile.
+- Concurrency 1. The infra container is a singleton (`bot-bottle-mac-infra`),
+  so two simultaneous runs on one host collide (#425). The job also declares a
+  `concurrency` group as belt-and-suspenders and tears the singleton down after
+  each run.
+
+### `integration-macos` job
+
+Modeled on `integration-firecracker`:
+
+- `runs-on: [self-hosted, macos]`.
+- `if:` `workflow_dispatch` only (advisory, manual dispatch; never push or PRs,
+  so no fork-PR exposure, no merge-blocking, and no unattended runs on push).
+- `concurrency: { group: integration-macos-infra, cancel-in-progress: false }`
+  to serialize runs against the singleton.
+- **Preflight** — `command -v container`, `container system status`, then
+  `./cli.py backend status --backend=macos-container`; any failure exits
+  non-zero so a misprovisioned runner fails loudly instead of silently
+  skipping.
+- Run the integration suite under coverage with
+  `BOT_BOTTLE_BACKEND=macos-container` and print a `coverage report -m` for
+  visibility (no upload, not in the gate).
+- **Teardown** (`if: always()`) — `MacosInfraService().stop()` removes the
+  singleton so a crashed run cannot wedge the next one.
+
+### The `test_sandbox_escape` CI guard (the trap #470 left)
+
+`TestSandboxEscape` is the only backend-agnostic integration test that boots a
+real bottle, so it is the one that would catch a macOS launch regression. It
+still carries a second guard that skips under `GITEA_ACTIONS` for every backend
+except `firecracker`:
+
+```python
+@unittest.skipIf(
+    os.environ.get("GITEA_ACTIONS") == "true"
+    and os.environ.get("BOT_BOTTLE_BACKEND") != "firecracker",
+    ...,
+)
+```
+
+The skip exists because the *containerized* `act_runner` (docker on
+`ubuntu-latest`) can't see a host bind mount and hides sibling-gateway network
+topology. Those constraints do not apply to a **host-mode** runner — neither
+the KVM host runner nor a macOS host runner is containerized. This PRD relaxes
+the guard to allow both host-mode backends (`firecracker`, `macos-container`)
+through while still skipping on the containerized Docker job. Without this
+change the macOS job would run green while skipping the exact test that proves
+the backend launches — the very false-green this issue is about.
+
+## Open questions
+
+- None known that block the job. git-gate is fully implemented on the macOS
+  backend (the gateway's consolidated `git-http` daemon plus dynamic key
+  provisioning/revocation), so `TestSandboxEscape` attack 5 — secret exfil
+  pushed through git-gate, rejected by the gitleaks hook before the upstream
+  push — runs the same as on the other backends. Any genuinely
+  macOS-specific test adjustment would surface at first runner bring-up, but
+  none is anticipated from the current backend implementation.

+
+## Summary
+
+Add a proper Python package distribution (`pyproject.toml` with a
+`bot-bottle` entry point) plus a thin `install.sh` bootstrapper, so users
+can install bot-bottle with a single command instead of cloning the repo
+and invoking `cli.py` directly. A new `bot-bottle doctor` subcommand
+verifies host prerequisites after install.
+
+## Problem
+
+There is currently no install path for new users. The only way to run
+bot-bottle is to clone the repo and invoke `./cli.py`. This blocks any
+public demo: readers want `curl | sh` or `pipx install`, not a manual
+clone-and-configure flow. There is also no single command that tells a
+user whether their host is actually ready to run a bottle.
+
+## Goals / Success Criteria
+
+- `curl -fsSL <raw-url>/install.sh | sh` leaves a working `bot-bottle`
+  command on PATH.
+- Python-native users can install with `pipx install bot-bottle` or
+  `uv tool install bot-bottle` (once published) — or from a local
+  checkout today.
+- `install.sh` validates prerequisites (Python ≥ 3.11), creates the
+  `~/.bot-bottle/` config tree, installs the package, and runs
+  `bot-bottle doctor`. It never installs Docker or a VM backend silently
+  and never uses `sudo`.
+- `install.sh` is idempotent — safe to re-run.
+- `bot-bottle doctor` reports Python version, backend *readiness*, and
+  config-dir presence, exiting non-zero when a hard prerequisite is unmet.
+- The package keeps **zero runtime pip dependencies** (stdlib-only,
+  matching the existing constraint in `AGENTS.md`).
+
+## Non-goals
+
+- Bundling a Python runtime or producing a standalone binary.
+- Automatic Docker / VM-backend installation.
+- Plugin-architecture changes (issue #197 floats a containerized-plugin
+  direction; that's a separate feature).
+- Publishing to a package index in this PR — the package *structure* is
+  the deliverable; publishing is a follow-up step.
+
+## Design
+
+### Package structure (`pyproject.toml`)
+
+Fill out the previously-stub `pyproject.toml` with project metadata, a
+console-script entry point, and package-data for the non-Python assets the
+runtime reads from inside the package:
+
+```toml
+[project]
+name = "bot-bottle"
+version = "0.1.0"
+requires-python = ">=3.11"
+dependencies = []
+
+[project.scripts]
+bot-bottle = "bot_bottle.cli:main"
+```
+
+`bot_bottle.cli:main` already exists (the `cli.py` shim calls it), so no
+refactor of the entry point is needed. `package-data` ships the non-Python
+assets that live *inside* the package (`egress_entrypoint.sh`, the contrib
+Dockerfiles, the firecracker netpool defaults, the macos-container init
+script).
+
+### Self-contained wheel (build resources)
+
+The gateway / infra / orchestrator images are built from a Docker (or Apple
+`container`) build context that must contain the `bot_bottle` package,
+`pyproject.toml`, and the **root-level** Dockerfiles as siblings. Several
+modules used to locate that context by walking `__file__`'s parents to the
+repo root (`_REPO_ROOT = Path(__file__)…parents[N]`) and reading
+`Dockerfile.gateway`, `nix/firecracker-netpool.nix`, and
+`scripts/firecracker-netpool.sh` from it. In an installed wheel the package
+lives in `site-packages` with no repo root above it, so those reads fail —
+`doctor` passes but `start` / backend setup breaks.
+
+Fix: a single resolver, `bot_bottle/resources.py`.
+
+- `build_root()` returns a directory shaped like a repo root (has
+  `bot_bottle/`, `pyproject.toml`, the Dockerfiles, `nix/`, `scripts/`).
+  In a **checkout** it's the repo root itself — unchanged behavior. From an
+  **installed wheel** it stages a copy under the app-data dir, keyed by a
+  **content digest** of the installed package + bundled resources (not the
+  distribution version): the installer defaults to a git branch and
+  `pipx install --force` while `version` stays `0.1.0`, so a version key
+  would reuse a previous commit's tree — the digest key re-stages instead.
+  Staging is concurrency-safe: a file lock serializes it, each writer builds
+  into a private temp dir, and the finished tree is published with an atomic
+  rename (never populating a shared path another process might read).
+- The root-level resources are shipped inside the wheel under
+  `bot_bottle/_resources/` by a `setup.py` `build_py` step (kept in sync
+  with `resources.BUNDLED_RESOURCES`); `MANIFEST.in` includes them in the
+  sdist.
+- Every former `_REPO_ROOT` / `_REPO_DIR` call site now derives from
+  `resources`: the docker/macos agent-image launch, each backend's
+  `orchestrator` / `gateway` / `infra` service, firecracker `infra_vm` /
+  `infra_artifact` / `setup`, and the shared `gateway` build context. So
+  checkout and wheel installs share one downstream path.
+
+Verification: `test_resources` exercises both layouts — including the staged
+wheel context, a re-stage when package content changes at the same version,
+and a rebuild of a partial (crashed) stage. `test_wheel_install` builds the
+wheel, installs it into an isolated venv, and asserts `bot-bottle doctor`
+runs and `build_root()` produces a valid context; `build` is in
+`requirements-dev.txt` so it runs in CI, and a build/install failure fails
+the test (it does not skip). Running `start` end-to-end still needs a
+Docker/KVM host (CI), not a source checkout.
+
+### `install.sh`
+
+A POSIX `sh` bootstrapper that:
+
+1. Checks `python3` is present and ≥ 3.11; exits with a clear message
+   otherwise.
+2. Checks `git` when installing a `git+` spec, and — when falling back to
+   pip — that pip is usable and the interpreter isn't externally managed
+   (PEP 668), pointing at pipx otherwise.
+3. Creates `~/.bot-bottle/{agents,bottles,contrib}`.
+4. Installs via `pipx` if available, else `python3 -m pip install --user`.
+   The spec defaults to the git URL and is overridable via
+   `BOT_BOTTLE_INSTALL_SPEC` (used by tests / local installs).
+5. Locates the `bot-bottle` entry point: PATH first, else the
+   interpreter's own user-scheme scripts dir resolved via `sysconfig`
+   (`~/.local/bin` on Linux, `~/Library/Python/<X.Y>/bin` on a python.org
+   macOS interpreter — not hardcoded).
+6. Runs `bot-bottle doctor` and reports the result.
+
+It is idempotent and never calls `sudo`.
+
+### `bot-bottle doctor`
+
+A new store-free subcommand (no DB migration required) that checks and
+reports:
+
+- **python** — interpreter version (hard requirement: ≥ 3.11).
+- **backend** — at least one backend *ready* on this host
+  (macos-container / firecracker / docker), via `is_backend_ready()` — a
+  full backend `status()` probe (daemon reachable, network pool present,
+  KVM usable), not a PATH-only check: a stopped daemon or half-configured
+  backend must not report `ok` when `start` can't work. Each not-ready
+  backend prints its own diagnostics. Hard requirement.
+- **config** — whether `~/.bot-bottle/` exists (advisory only; `start`
+  provisions on first run).
+
+Exits 0 when both hard requirements pass, non-zero otherwise.
+
+## Testing strategy
+
+- Unit test `bot-bottle doctor` success/failure paths with backend
+  readiness (`is_backend_ready`) and Python version mocked, including the
+  available-but-not-ready → fail case.
+- Unit test that `pyproject.toml` parses, declares the entry point and an
+  empty `dependencies` list, and that every `package-data` glob resolves
+  to a file that exists on disk (guards against drift).
+- Unit test that `install.sh` is executable, POSIX-ish (`set -eu`), never
+  calls `sudo`, and runs `doctor` after install.
+
+## Open questions
+
+- Should `version` be derived from a git tag at build time (e.g.
+  `hatch-vcs`) or kept static? Static (`0.1.0`) is simpler for now.
+- Publishing target (PyPI vs. a self-hosted index) is deferred.
