fix(doctor): survive a PATH entry the user can't execute

The install itself now works end to end on a fresh macOS account — venv built,
package installed from git, entry point linked — and `doctor` then died with an
unhandled traceback:

    PermissionError: [Errno 13] Permission denied: 'ip'

netpool's probe helpers caught only FileNotFoundError. That is not the only way
a probe binary can be unavailable: when a name on PATH exists but this user
cannot execute it, exec fails with EACCES, and CPython reports that in
preference to the ENOENT from the other PATH entries. So `except
FileNotFoundError` misses it and the crash propagates all the way out of
`doctor`. Reproduced directly: a mode-000 file named `ip` on PATH yields
exactly the error above.

_run_ok's docstring already stated the intent — treat an unavailable binary as
failure rather than crashing — so this widens the catch to OSError to match
what it says. Any OSError means the probe could not run, which for a
fail-closed check is indistinguishable from "not present". The same narrow
catch is fixed in overlapping_routes and in the two docker probes
(compose ls, docker ps), which are the same shape and equally reachable.

Deliberately not touched: the FileNotFoundError catches around file I/O in
bottle_state and orchestrator/service, where the narrow exception is correct.

The harness also required `bot-bottle` on PATH before running doctor, which
could never be true: install.sh prints the PATH line rather than editing a
shell profile, by design, so on a fresh account the entry point is installed
and working but not on PATH. It now looks where the installer actually puts
it (~/.local/bin, then the venv) and notes when it's running by absolute path.
That was the harness failing a run for a reason the installer intends.

 ## Quickstart
 
-On compatible macOS hosts, the default backend requires Apple's `container` CLI and does not require Docker. The Firecracker backend (Linux) requires Docker on the host for the gateway plus the `firecracker` binary and KVM. 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`.
+```sh
+curl -fsSL https://gitea.dideric.is/didericis/bot-bottle/raw/branch/main/install.sh | sh
+```
+
+The installer is a bootstrapper: it finds a suitable Python, installs bot-bottle with `pipx` (falling back to `pip --user`), creates `~/.bot-bottle`, and runs `bot-bottle doctor`. It is idempotent and never uses `sudo`. Python-native users can skip it entirely with `pipx install bot-bottle` or `uv tool install bot-bottle`.
+
+### Requirements
+
+**Python ≥ 3.11**, and this is the one that trips people up on macOS: the `python3` Apple ships at `/usr/bin/python3` is **3.9.6**, which is too old. Bare `python3` resolves to that stub far more often than people expect. `path_helper` builds a login shell's `PATH` from `/etc/paths` and then appends `/etc/paths.d/*`, and `/usr/bin` sits in the former — so even when `/opt/homebrew/bin` *is* on the `PATH` (via `/etc/paths.d/homebrew`), it comes after `/usr/bin` and loses. Prepending a newer Python is something your shell profile does, and a fresh account, a launchd job, or a CI runner has no such profile. So the installer looks past bare `python3` before giving up: it tries `python3`, then the versioned `python3.11`–`python3.14` names, then `/opt/homebrew/bin`, `/usr/local/bin`, `~/.local/bin`, and python.org framework builds — and tells you which one it picked when it isn't the obvious one. Point it somewhere specific with `BOT_BOTTLE_PYTHON=/path/to/python3`.
+
+**No `pipx` required.** If `pipx` is present the installer uses it and stays out of the way. If it isn't, bot-bottle installs into a private venv at `~/.bot-bottle/venv` (override with `BOT_BOTTLE_VENV`) and symlinks the entry point into `~/.local/bin`. There is deliberately no `pip install --user` path: Homebrew, python.org and Debian/Ubuntu interpreters are all externally managed (PEP 668), which blocks `--user` outright — so on a Mac it is never the fallback it appears to be. A venv is exempt from PEP 668, and `venv` is stdlib, so unlike `pipx` there is nothing to bootstrap first.
+
+**`git`**, because the default install spec is a `git+` URL. Set `BOT_BOTTLE_INSTALL_SPEC` to a wheel path or index name to avoid it.
+
+**A backend**, which the installer deliberately does *not* install for you — `doctor` reports what's missing afterwards. On compatible macOS hosts, the default backend requires Apple's `container` CLI and does not require Docker. The Firecracker backend (Linux) requires Docker on the host for the gateway plus the `firecracker` binary and KVM. 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`.
 
 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.

+
+The `/supervise/propose` + `/supervise/poll` pair is the **agent** half of the
+supervise flow: the data plane (supervise / egress / git-gate) queues a proposal
+and polls for its response over RPC instead of opening `bot-bottle.db` directly.
+`poll` is idempotent — it never archives, so a dropped connection can't lose an
+operator decision (the row is reaped when the bottle is torn down / reconciled).
+Both attribute the caller by `(source_ip, identity_token)` exactly like
+`/resolve`, so a bottle can only ever queue or read its own proposals.
+
+`POST /bottles` / `DELETE` drive the full launch lifecycle: they mint (or
+tear down) the bottle in the registry AND broker the backend-native launch
+via the orchestrator. Register/deregister without a launch are internal to
+`OrchestratorCore`, not exposed here.
+
+Routing/handling is the pure function `dispatch()` so it is unit-testable
+without a socket; `Handler` / `OrchestratorServer` / `make_server` are a
+thin stdlib adapter around it. Listing redacts identity tokens — they are
+returned only once, to the caller that launches the bottle.

-# PRD 0082: Authoritative failure boundaries
-
-- **Status:** Draft
-- **Author:** codex
-- **Created:** 2026-07-27
-- **Issue:** #444
-
-## Summary
-
-Make every security- or lifecycle-sensitive snapshot distinguish authoritative
-empty state from unavailable state, and make every destructive or
-resource-consuming boundary revalidate the assumptions it acts on. This
-finishes the focused quality work begun under #444 without broad rewrites:
-cleanup cannot act on stale identities, policy introspection cannot publish a
-fabricated empty policy, gateway servers bound untrusted work, and daemon
-shutdown does not emit uncaught background-thread failures. Shared
-control-plane storage and gateway credential provisioning also enforce their
-filesystem security contract before sensitive data is written.
-
-## Problem
-
-Several paths are individually fail-closed but compose into unsafe or
-misleading behavior:
-
-1. `cleanup` prepares a plan, waits indefinitely for operator confirmation,
-   then kills stored PIDs and removes stored paths without checking that those
-   identities still describe the same orphan. A PID may be reused or a run
-   directory may become active during the prompt.
-2. The supervisor reuses egress's deny-all fallback for
-   `list-egress-routes`. Deny-all is correct for enforcement, but presenting it
-   as a successful empty route table can cause a later replace-all proposal to
-   discard live routes.
-3. The supervisor and Git HTTP services accept bounded declared body sizes but
-   use blocking reads and unbounded request threads. An untrusted bottle can
-   exhaust the shared gateway with slow or parallel requests.
-4. macOS cleanup enumerates containers and networks independently and treats a
-   failed query as an empty class, so a partial snapshot can still become a
-   destructive plan.
-5. Gateway log-pump threads race stream closure during shutdown and emit
-   uncaught exceptions even when shutdown otherwise succeeds.
-6. Firecracker discovers VMs through whitespace-split `pgrep -a` output.
-   A configured cache path containing spaces can hide a live VM from the
-   snapshot and make its run directory appear orphaned.
-7. Docker cleanup asks compose for its project snapshot in best-effort mode.
-   A transient query failure can therefore become an empty stopped-project
-   set and authorize deletion of associated state directories.
-8. Firecracker artifact downloads and registry publication have no network
-   deadline, so an unresponsive registry can hold setup or release work
-   indefinitely.
-9. Authenticated secret blobs select the unauthenticated legacy decoder when
-   their in-band version prefix is changed, allowing storage tampering to
-   bypass tag verification.
-10. Cleanup executes the entire post-confirmation snapshot rather than the
-    intersection with what the operator saw, and mutation failures are not
-    reflected in the command result.
-11. Git smart-HTTP can retain sixteen 100 MiB request bodies concurrently,
-    cleanup mutations have no subprocess deadline, and Firecracker signalling
-    failures bypass shared mutation accounting.
-12. SQLite creates the shared control-plane database before its mode is
-    restricted, then suppresses permission-repair failures. Gateway transports
-    also differ in whether copied deploy-key modes are preserved.
-
-These are one design problem: state used to authorize deletion, replacement,
-or resource allocation must be authoritative at the point of use.
-
-## Goals / Success Criteria
-
-- Cleanup never signals a PID or recursively deletes a path solely because it
-  appeared in a pre-confirmation snapshot.
-- Firecracker cleanup proves immediately before action that a PID is still the
-  same Firecracker process and that a run directory is still orphaned.
-- Firecracker process discovery reads NUL-delimited argv from `/proc`; paths
-  are never reconstructed from whitespace-delimited process listings.
-- All backend cleanup discovery primitives raise a typed enumeration error on
-  operational failure. No backend may independently continue from a partial
-  snapshot.
-- Shared cleanup control flow lives in the backend layer; concrete backends
-  override resource-specific discovery and validation primitives rather than
-  each implementing a bespoke failure policy.
-- `list-egress-routes` returns an MCP error when attribution or policy
-  resolution is unavailable. A genuine, authoritatively resolved empty policy
-  remains a successful empty list.
-- Supervisor and Git HTTP request bodies have total read deadlines, and each
-  service bounds concurrent request work. Limits apply to authenticated
-  callers because bottles themselves are untrusted.
-- Gateway child-output pumping treats expected stream closure during shutdown
-  as completion while preserving diagnostics for unexpected failures.
-- Artifact pull, existence-check, and publication requests use explicit
-  network deadlines.
-- Persisted secrets accept only the authenticated format. The schema migration
-  intentionally clears legacy rows; local agents are reprovisioned rather
-  than retaining a ciphertext-controlled downgrade path.
-- Cleanup executes only resources present in both the displayed and current
-  authoritative plans, attempts every approved mutation, and returns failure
-  when any mutation does not complete.
-- Git request bodies spool to disk behind a separate heavy-work semaphore;
-  cleanup commands have configurable deadlines; Firecracker signalling
-  failures aggregate while identity-verification uncertainty still aborts.
-- The shared database directory and file are private before SQLite writes any
-  control-plane state; an inability to enforce those modes aborts startup.
-- Gateway credential directories and files receive explicit private modes
-  inside the gateway, independent of Docker, Apple Container, or SSH copy
-  semantics.
-- Unit tests cover PID/path reuse, partial backend enumeration, transient
-  policy resolution failure, slow bodies, concurrency saturation, and stream
-  closure races.
-
-## Non-goals
-
-- Further decomposition solely to reduce module line counts.
-- Replacing gateway stdlib HTTP services with a web framework.
-- Changing egress matching, DLP decisions, proposal semantics, or backend
-  launch behavior beyond the synchronization required for safe cleanup.
-- Making cleanup silently skip uncertain resources. Uncertainty is an
-  operator-visible failure.
-
-## Design
-
-### Shared backend control flow
-
-Follow the backend architecture rule used by gateway attachment: shared
-behavior lives above concrete backends; subclasses provide primitives, not
-control flow.
-
-Cleanup remains previewable, but confirmation authorizes a *new authoritative
-evaluation*, not blind execution of the displayed object. The shared flow:
-
-1. asks each available backend for a preview;
-2. displays the union and asks for confirmation;
-3. refreshes each non-empty backend plan;
-4. validates destructive identities immediately before action;
-5. aborts loudly if the refreshed plan or any identity cannot be proven safe.
-
-Backend-specific primitives define how to identify a resource. Firecracker
-uses process start identity plus canonical config/run paths; container
-backends use authoritative CLI queries and stable resource names/labels.
-
-Container engines expose destructive name-based commands without a portable
-compare-and-delete operation. Cleanup therefore refreshes after confirmation
-and requires every discovery query to succeed, minimizing but not claiming to
-eliminate the final name-reuse race. A future engine-specific stable-ID
-primitive may close that residual window without moving control flow back
-into each backend.
-
-### Enforcement state versus introspection state
-
-Egress enforcement retains its deny-all fallback because uncertainty must not
-grant network access. Supervisor introspection uses a strict resolver path:
-unattributed callers and resolver failures become typed MCP errors, while a
-successfully resolved policy containing zero routes returns `routes: []`.
-
-### Gateway resource boundaries
-
-Both stdlib servers set a per-connection body deadline before reading and use a
-bounded request executor or semaphore. Saturated capacity fails quickly with a
-service-unavailable response. Existing size caps remain independent:
-supervisor proposals retain the 1 MiB cap and Git pack requests retain their
-larger protocol-appropriate cap.
-
-### Shutdown diagnostics
-
-The gateway output pump catches only stream-closure exceptions expected after
-the supervisor closes child pipes. Other I/O failures remain visible and are
-reported through the supervisor's normal diagnostic channel.
-
-### Shared filesystem security
-
-The common SQLite store owns database creation for every backend. It creates
-the parent directory and an empty database with private modes before opening
-SQLite, repairs existing modes, verifies the resulting state, and propagates
-every enforcement failure. Backend launchers do not duplicate this policy.
-
-The backend-neutral gateway provisioner likewise applies directory and file
-modes after transport copies complete. This avoids relying on copy behavior
-that differs among Docker, Apple Container, and Firecracker's SSH transport.
-
-## Implementation chunks
-
-1. Existing fail-closed security and backend enumeration fixes.
-2. FastAPI orchestrator transport and bounded control-plane bodies.
-3. Egress request-policy and outbound-DLP pipeline extraction.
-4. Supervisor MCP dispatch extraction.
-5. Shared cleanup refresh/revalidation plus authoritative macOS discovery.
-6. Strict supervisor introspection and bounded supervisor/Git HTTP work.
-7. Gateway shutdown log-pump closure handling.
-8. Lossless Firecracker process identities, authoritative Docker cleanup
-   queries, and bounded Firecracker artifact transfers.
-9. Mandatory authenticated secret storage, shared cleanup-plan intersection
-   and mutation accounting, and contained Git backend process failures.
-10. Disk-spooled and separately bounded Git bodies, cleanup command deadlines,
-    and classified Firecracker signalling failures.
-11. Fail-closed shared database creation and backend-neutral gateway credential
-    permissions.

+### Black LLAB
+
+- **Source**: https://github.com/isaacdear/black-llab ;
+  HN launch https://news.ycombinator.com/item?id=47402394
+- **Isolation/locality**: Local Docker environment, with an isolated container
+  created for each agent task. Shared host kernel; no stronger boundary is
+  claimed.
+- **Agent integration**: General local/cloud model workspace. Its headline is
+  dynamic routing of simple prompts to local models and complex prompts to
+  hosted models, with code execution and web scraping inside the task
+  container.
+- **Network/credentials**: No default-deny egress, payload inspection, or
+  host-side credential injection documented in the launch.
+- **Competitive read**: Superficial overlap ("a container per agent task"),
+  but not a direct security-policy competitor. Its useful challenge is the
+  integrated model-selection UX, which bot-bottle intentionally leaves to the
+  selected agent provider.
+- **Maturity**: Early solo project; HN launch received 1 point.
+
+### Eve
+
+- **Source**: https://eve.new/ ;
+  HN launch https://news.ycombinator.com/item?id=47721255
+- **Isolation/locality**: Managed, hosted Linux sandbox per user/session
+  (claimed 2 vCPU, 4 GB RAM, 10 GB disk), with filesystem, code execution,
+  headless Chromium, and service connectors.
+- **Agent integration**: End-user OpenClaw-style agent product. An orchestrator
+  routes subtasks to specialist models and can run parallel subagents that
+  coordinate through a shared filesystem. Web UI and iMessage are primary
+  interaction surfaces.
+- **Network/credentials**: Broad connectors are a product feature; the launch
+  does not document bot-bottle-style default-deny route policy, content DLP,
+  or credentials held outside the sandbox.
+- **Competitive read**: Adjacent, not direct. Eve sells a managed colleague;
+  bot-bottle lets an operator run existing coding-agent CLIs under local
+  containment. Eve nevertheless demonstrates the appeal of background work,
+  live progress, browser capability, and mobile notification.
+- **Maturity**: Commercial hosted product; HN launch received 71 points and
+  39 comments.

+  HN launch https://news.ycombinator.com/item?id=47006393
+- **Isolation/locality**: Claude Code or Codex runs locally and provisions
+  remote cloud VMs/GPUs for execution. Project files are uploaded to the VM;
+  each machine exposes auth-protected VNC, VS Code, and Jupyter surfaces.
+- **Agent integration**: A skill plus CLI lets the coding agent itself start,
+  command, inspect, and tear down machines. Browser automation is integrated,
+  including snapshots and screenshots. Parallel disposable compute is the
+  central workflow.
+- **Network/credentials**: The launch emphasizes remote resource isolation and
+  authenticated UI endpoints, not default-deny guest egress, payload DLP, or
+  proxy-held application credentials.
+- **Competitive read**: The closest recent workflow competitor. It directly
+  addresses parallel coding agents, environmental conflict, and closing the
+  browser/test loop, but trades local custody for elastic cloud compute.
+  Cloud VMs and GPUs could be a future bot-bottle backend; they do not replace
+  its manifest/policy layer.

+### Nucleus
+
+- **Source**: https://github.com/coproduct-opensource/nucleus ;
+  HN launch https://news.ycombinator.com/item?id=46855770
+- **Isolation/locality**: Firecracker microVM with an enforcing MCP tool proxy.
+- **Agent integration/config**: Compositional permission envelope for
+  read/write/run actions. The envelope is non-escalating and can tighten or
+  terminate, with scoped approval tokens for gated operations.
+- **Network/credentials**: Default-deny egress, DNS allowlist, iptables drift
+  detection, time/budget caps, and hash-chained audit logging are claimed.
+  Remote append-only audit storage and attestation were roadmap items at
+  launch.
+- **Competitive read**: Direct on security architecture, especially
+  non-escalating policy and tamper-evident audit. It is an early execution/tool
+  proxy rather than a provider-neutral, one-command coding-agent product. Its
+  tool-level action envelope is semantically finer than bot-bottle's network
+  boundary; bot-bottle is stronger on turnkey agent/provider integration,
+  credential custody, Git mediation, and long-running operator workflow.

+  HN launch https://news.ycombinator.com/item?id=46706796
+- **Isolation/locality**: Local sandbox for running multiple coding agents in
+  YOLO mode. The launch discussion describes a VM boundary.
+- **Agent integration**: Built around the native Claude Code experience and
+  motivated by running many agents in parallel without permission-prompt
+  fatigue.
+- **Network/Git/credentials**: Strict egress filtering, configurable HTTP
+  middleware, and mediated `git`/`gh` dispatch are the main value. The launch
+  discussion explicitly identifies provider credential handling as unfinished
+  and difficult because Claude state spans multiple host paths.
+- **Competitive read**: The closest new threat-model competitor. It shares
+  bot-bottle's premise that filesystem isolation alone is insufficient and
+  that Git plus authorized HTTP channels need mediation. bot-bottle currently
+  leads on cross-provider support, proxy-held Claude/Codex/forge credentials,
+  typed per-role manifests, content DLP, and supervision. yolo-cage's simpler
+  pitch and narrower Claude-first setup may be easier to explain.

+
+### Sandbox Agent SDK
+
+- **Source**: https://github.com/rivet-dev/sandbox-agent ;
+  HN launch https://news.ycombinator.com/item?id=46795584
+- **Isolation/locality**: Does not provide the isolation primitive. It runs
+  inside E2B, Daytona, Modal, Cloudflare Containers, Agent Computer, BoxLite,
+  Docker, or another sandbox provider. Embedded mode can also run locally
+  without a sandbox.
+- **Agent integration**: Provider-neutral Rust server/SDK exposing a common
+  HTTP/SSE/OpenAPI interface across Claude Code, Codex, OpenCode, Cursor, Amp,
+  and Pi, plus a universal event/session schema for external storage and
+  replay. It also exposes filesystem, managed-process, terminal, MCP, skills,
+  custom-tool, and computer-use APIs. TypeScript is the primary SDK surface.
+- **Network/credentials**: Delegated to the chosen sandbox provider.
+- **Credential posture**: Its documented convenience command extracts real
+  OpenAI/Anthropic credentials from local agent configuration and passes them
+  as environment variables into the sandbox. That is materially weaker than
+  bot-bottle's host-side credential custody, but it is an integration choice,
+  not a structural limitation: a sandbox provider could put a credential
+  proxy underneath the same SDK.
+- **Competitive read**: A serious architectural threat despite not supplying
+  isolation. Sandbox Agent is trying to standardize the boundary *above* the
+  sandbox: one client protocol, session model, and UI/control surface across
+  every coding agent and runtime. If that boundary becomes the ecosystem
+  standard, users and application builders may choose a sandbox provider plus
+  Sandbox Agent rather than a vertically integrated launcher. bot-bottle's
+  manifests would then be valuable chiefly as a local policy/backend
+  implementation unless they expose an equally usable control contract.
+- **Maturity**: Apache 2.0, ~1.5k stars and 426 commits at the 2026-07-27
+  check; HN launch received 41 points.
+
+#### Why the Sandbox Agent architecture is strategically different
+
+The manifest and the universal control protocol solve different layers:
+
+- A bot-bottle manifest is a **trusted launch-time policy composition**. It
+  selects the agent role, isolation backend, image, skills, egress routes,
+  credentials, Git mediation, and supervision policy. Crucially, identity and
+  secret references live on the host side of the trust boundary.
+- Sandbox Agent is a **runtime control and observation protocol**. A remote
+  client creates sessions, sends messages, handles permissions, configures
+  skills/MCP, manipulates files/processes/desktops, and streams normalized
+  events. It deliberately delegates sandbox lifecycle, Git management,
+  storage, network policy, and credential security to other products.
+
+That makes it complementary in a component diagram but competitive in product
+architecture. The layer that becomes the stable integration point tends to own
+the ecosystem. Three plausible threat paths matter:
+
+1. **Standard control plane, interchangeable runtimes.** Applications integrate
+   once with Sandbox Agent and treat E2B, Daytona, BoxLite, Docker, or a future
+   local microVM as replaceable compute. A provider that bundles adequate
+   egress and credential custody makes bot-bottle's end-to-end launcher less
+   necessary.
+2. **Policy grows upward.** Sandbox Agent already configures permissions,
+   skills, MCP, custom tools, filesystem/process access, and computer use. If
+   it adds a declarative, host-verifiable policy document, the overlap with
+   agent/bottle manifests becomes substantial even if enforcement remains
+   delegated.
+3. **UI and session ownership.** Its universal transcript schema, Inspector,
+   React components, event replay, and remote terminal/computer APIs can become
+   the natural basis for desktop, web, and mobile agent managers. bot-bottle's
+   security layer could remain stronger while losing the operator surface and
+   distribution channel.
+
+The counter-position is not to claim that manifests and an API are mutually
+exclusive. The defensible split is:
+
+- bot-bottle owns the trusted policy and enforcement plane outside the agent;
+- a provider-neutral protocol owns agent process control and normalized
+  events; and
+- the operator UI consumes both.
+
+This suggests an explicit compatibility decision rather than parallel,
+accidental protocol design: evaluate running Sandbox Agent inside a bottle and
+exposing it only through the authenticated bot-bottle control plane. If its
+schema is suitable, adopting it could turn a threat into an integration while
+keeping manifests as the higher-trust policy source. If it is unsuitable,
+bot-bottle should still publish a stable provider-neutral session/event API so
+frontends do not depend on Claude/Codex/Pi-specific process behavior.

+
+## Gap evaluation after the 2026-07-27 entrant scan
+
+### Material gaps
+
+1. **A stable provider-neutral control and event protocol.** This is the
+   largest newly visible gap. bot-bottle normalizes launch/provisioning across
+   providers, but an external UI or orchestrator still lacks one documented
+   contract for creating a Claude/Codex/Pi session, sending input, handling
+   permission/supervision events, streaming normalized output, reconnecting,
+   and replaying history. Sandbox Agent SDK addresses exactly this layer and
+   is already portable across many sandbox providers.
+2. **Browser/preview closure.** CloudRouter and Eve make a browser or desktop
+   part of the standard agent environment and expose screenshots/live viewing
+   to the operator. bot-bottle can run dev servers and supports nested
+   containers, but it does not present a first-class browser/computer-use
+   primitive or an auth-protected preview surface. For coding agents expected
+   to verify UI work, this is a real product gap.
+3. **Unified parallel-session operator UX.** Named persistent bottles and
+   supervision provide the substrate, but the recent products make task
+   switching, live progress, notifications, terminal attach, diffs, and
+   session history the product. Security depth will not compensate for a
+   visibly rougher daily loop.
+4. **Normalized transcript persistence and replay.** bot-bottle preserves
+   provider-specific state for resume; it does not expose a provider-neutral
+   event record suitable for audit, replay, analytics, or a web/mobile client.
+   This is both a UX gap and an audit gap.
+
+### Important, but not necessarily bot-bottle features
+
+- **Cloud VM/GPU provisioning.** Valuable for elastic workloads and could be a
+  backend, but it conflicts with the local-custody default and should not
+  displace core policy work.
+- **Automatic model routing.** Black LLAB and Eve sell task-to-model routing.
+  bot-bottle's provider-template boundary can host that choice without making
+  it part of the trusted sandbox policy.
+- **A thousand SaaS connectors.** This broadens capability and blast radius.
+  The bot-bottle-native answer should remain explicit, scoped forge/egress
+  associations rather than connector count as a goal.
+- **SDK-driven sandbox lifecycle as the primary configuration model.** Useful
+  for platform builders, but not a replacement for reviewable, host-owned
+  manifests. A control API and a declarative policy source are compatible;
+  neither should silently become the other.
+
+### Areas where bot-bottle remains ahead
+
+- real provider and forge credentials remain outside the agent process rather
+  than being extracted into its environment;
+- authorized HTTP payloads are scanned, not merely destination-filtered;
+- Git writes traverse a distinct gate with secret scanning and host-held

+- role policy is host-owned, composable, and separate from untrusted repo

+# Testing a clean bot-bottle install on macOS
+
+How do you exercise `install.sh` (and, ideally, a first `bot-bottle start`)
+the way a brand-new user would — on a pristine macOS environment you can
+throw away afterward — *without* permanently polluting your daily-driver
+Mac? The user's framing: is there a VM or boundary that avoids creating a
+separate account, or is spinning up and tearing down a throwaway macOS
+user on the CLI easy enough to just do that?
+
+## Summary
+
+There is no lightweight, in-place macOS sandbox that hands you a clean home
+directory and wipeable system state without *either* a VM or a separate
+user account. `sandbox-exec` (Seatbelt) is deprecated and confines a
+process, not an environment; App Sandbox is for shipping apps, not for
+provisioning a fresh dev host. So the real choice is exactly the two the
+user named: **a disposable macOS VM** or **a throwaway user account** —
+and which one is right turns on a detail specific to *this* project.
+
+bot-bottle's default macOS backend is Apple's `container`, which runs each
+container in its own lightweight VM via `Virtualization.framework`
+([`README.md:27`](../README.md), [`apple-container-backend.md`](apple-container-backend.md)).
+That means a full end-to-end test — install *and* `bot-bottle start` —
+needs virtualization to work wherever bot-bottle runs. Inside a macOS guest
+VM that requires **nested virtualization, which Apple gates to M3 or newer
+chips on macOS 15+**. On M1/M2 you cannot run the Apple Container backend
+(or Docker Desktop, same reason) inside a macOS VM at all.
+
+The recommendation splits on what you're testing and what silicon you have:
+
+- **Install-script correctness only** (does `curl | sh` → pipx → config dir
+  → `doctor`'s Python/config checks pass?): a **disposable Tart VM** is the
+  cleanest boundary and works on any Apple Silicon Mac. `doctor` will report
+  the backend as not-ready inside the VM on M1/M2, which is fine — you're
+  testing the installer, not the runtime.
+- **Full runtime** (actually launch a bottle) on **M3/M4**: a **disposable
+  Tart VM from a golden base image, cloned per run** is the gold standard —
+  a genuine kernel/state boundary that wipes to nothing.
+- **Full runtime** on **M1/M2**, or when you'd rather not fight nested virt:
+  a **throwaway admin user via `sysadminctl`** is the pragmatic pick. It
+  tests the real backend because the backend runs on the host hypervisor —
+  but it is a *hygiene* boundary, not a security one, and it does **not**
+  clean the system-level footprint (see below).
+
+Prefer the VM. Reach for the throwaway user only when nested virt is off the
+table and you accept an imperfect wipe.
+
+## Why "a boundary without a separate user" doesn't really exist on macOS
+
+macOS has no namespace/overlay story like Linux `unshare` + tmpfs. The
+options that sound like in-place sandboxes don't fit:
+
+| Mechanism | Why it doesn't give you a clean, wipeable env |
+|---|---|
+| `sandbox-exec` / Seatbelt | Officially deprecated; confines *one process's* syscalls against a profile. It cannot present a fresh `$HOME` or a pristine `/usr/local`, and it won't let the Apple Container system service work. |
+| App Sandbox | Entitlement-based confinement for signed `.app` bundles, not a provisioning tool for a CLI dev environment. |
+| A second `$HOME` via `HOME=/tmp/foo` | Redirects only what honors `$HOME`. `install.sh` mostly does (it writes `~/.bot-bottle` and pipx/pip `--user` paths), but the Apple `container` install lands in `/usr/local` + a **system service**, and Homebrew lands in `/opt/homebrew` — all outside any `$HOME` you set. You'd get a false sense of "clean." |
+| APFS snapshot rollback (`tmutil localsnapshot`) | You can't roll the live boot volume back to a local snapshot without booting to Recovery; it's not a per-run userspace undo. |
+
+So the honest answer to "is there some boundary that avoids a separate
+user?": yes — a **VM** — and it's the *stronger* boundary anyway. The only
+lighter-weight option is the separate user, with the caveats below.
+
+## What a clean install actually touches (the footprint that decides "wipeable")
+
+Grounding the teardown story in what `install.sh` and the backend create:
+
+| Artifact | Location | In `$HOME`? | Survives user deletion? |
+|---|---|---|---|
+| Config / state / db | `~/.bot-bottle/{agents,bottles,contrib,state,db}` ([`install.sh:80-83`](../install.sh), [`bot_bottle/paths.py:59`](../bot_bottle/paths.py)) | ✅ | ❌ removed with home |
+| pipx venv + shim | `~/.local/pipx/venvs/bot-bottle`, shim in `~/.local/bin` ([`install.sh:87-89`](../install.sh)) | ✅ | ❌ removed with home |
+| private venv fallback (no pipx) | `~/.bot-bottle/venv` + symlink in `~/.local/bin` ([`install.sh`](../install.sh)) | ✅ | ❌ removed with home |
+| PATH / token exports | shell profile (`~/.zprofile`, etc.); `BOT_BOTTLE_CLAUDE_OAUTH_TOKEN` ([`README.md:74`](../README.md)) | ✅ | ❌ removed with home |
+| **Apple `container` install** | `/usr/local/...` + notarized `.pkg` receipts | ❌ | ✅ **stays** |
+| **Apple `container` system service** | launchd system service (`container system start`) | ❌ | ✅ **stays** |
+| **Homebrew** (if used for `container`/python) | `/opt/homebrew` | ❌ | ✅ **stays** |
+| Rosetta 2 (needed for image builds) | system | ❌ | ✅ **stays** |
+
+The three bold rows are the crux: **deleting the throwaway user does not
+uninstall the Apple Container runtime, its system service, Homebrew, or
+Rosetta.** A VM, by contrast, wipes 100% of the above by definition —
+that's its entire advantage for this task.
+
+## Option A — Disposable Tart VM (recommended)
+
+[Tart](https://tart.run) is a CLI-first macOS/Linux VM manager built on
+`Virtualization.framework`, purpose-built for exactly this "does it work on
+a clean macOS, without my settings/permissions/data" workflow. Keep one
+pristine *golden* image, clone a throwaway per run, delete it after.
+
+```sh
+brew install cirruslabs/cli/tart
+
+# One-time: build a golden base (either a prebuilt image or a vanilla IPSW).
+tart clone ghcr.io/cirruslabs/macos-tahoe-base:latest golden   # ~25 GB pull
+# — or a truly vanilla install you click through once —
+# tart create golden --from-ipsw latest --disk-size 60
+
+# Per test run: clone → boot → test → destroy.
+tart clone golden test-run
+tart run test-run &
+ssh admin@"$(tart ip test-run)"
+#   inside the guest:
+#   curl -fsSL https://gitea.dideric.is/didericis/bot-bottle/raw/branch/main/install.sh | sh
+#   bot-bottle doctor
+tart stop test-run
+tart delete test-run          # back to pristine; golden is untouched
+```
+
+Cloning is cheap (sparse files), so the golden image is your reset button —
+every `tart clone` is a fresh macOS. This is the closest thing to a Linux
+`docker run --rm` for a whole Mac.
+
+**The nested-virt caveat (read before relying on it for runtime tests).**
+The Apple Container backend inside the guest needs
+`Virtualization.framework` to work *inside* the VM. Apple enables nested
+virtualization only on **M3 or newer**, on **macOS 15 (Sequoia) or later**;
+M2 and earlier are excluded by Apple, confirmed by Apple DTS. Consequences:
+
+- **M3/M4 host:** full runtime works in the guest. `bot-bottle doctor`
+  reports the backend ready and `start` can launch a bottle. Gold standard.
+- **M1/M2 host:** the guest can install bot-bottle and pass the Python /
+  config-dir checks, but `doctor`'s backend check will fail and you cannot
+  launch a bottle in the VM. Still perfectly good for testing *the
+  installer*; not for the runtime.
+- **M4-specific:** a known bug blocks pre-Ventura guests on M4; use a
+  current macOS guest (which you want anyway, since Apple `container`
+  targets macOS 26 Tahoe).
+
+UTM is the GUI equivalent on the same framework (and was first to expose
+nested virt) if you'd rather click; Tart wins for a scriptable
+spin-up/tear-down loop.
+
+## Option B — Throwaway user via `sysadminctl` (pragmatic fallback)
+
+Creating and deleting a user from the CLI is genuinely a two-liner, and it
+tests the **real** backend on any Apple Silicon Mac because the backend runs
+on the host hypervisor — no nested virt needed.
+
+```sh
+# Create a self-contained admin user (admin needed for the container service).
+sudo sysadminctl -addUser bbtest -fullName "bot-bottle test" \
+    -password 'throwaway' -admin
+
+# Log into that account (fast-user-switch or the login window), then run the
+# installer as bbtest exactly as a new user would. When done:
+
+sudo sysadminctl -deleteUser bbtest -secure   # -secure erases the home dir
+```
+
+Honest accounting of what this does and doesn't buy you:
+
+- **Boundary strength:** it's a *hygiene / fresh-`$HOME`* boundary, **not a
+  security boundary.** Same kernel, same admin group; an admin test user can
+  touch system state. If the point is "clean environment," fine. If the point
+  is "contain something untrusted," this is the wrong tool — use a VM.
+- **Wipe completeness:** `-secure` erases the home dir (so `~/.bot-bottle`,
+  the pipx venv, and profile exports go away), but as the footprint table
+  shows, the **Apple Container runtime, its launchd system service,
+  Homebrew, and Rosetta persist.** For a truly repeatable "did a *system with
+  nothing installed* work?" test, that residue defeats the purpose — the
+  second run isn't clean.
+- **Operational gotchas:** don't pass real passwords on the command line (they
+  land in `ps` and history — this is a throwaway credential, so it's
+  tolerable here). Deletion must run as root from a normally-booted, admin-
+  logged-in session; the Terminal needs **Full Disk Access** or you'll hit
+  error `-14120` and a half-deleted account. Prefer letting the system place
+  the home dir (don't pass `-home`), or deletion can orphan it.
+
+Use this when you're on M1/M2, you specifically want to exercise the live
+backend, and you can tolerate the system-level runtime staying installed
+between runs (or you uninstall Apple `container` / brew by hand to reset).
+
+## Honorable mentions
+
+- **External bootable macOS volume.** A fresh macOS on an external SSD (or a
+  separate APFS volume) is bare-metal disposable: no nested-virt limit, real
+  backend works, and you `diskutil` the volume away to reset. Cost is reboot
+  friction per run — good for an occasional thorough pass, poor for a tight
+  loop.
+- **Rented / cloud Mac.** AWS EC2 Mac (dedicated Mac minis), Scaleway Apple
+  silicon, or MacStadium give a genuinely throwaway host you release when
+  done. Overkill for local iteration, but this is essentially what the
+  project's own advisory `integration-macos` CI job needs — a self-hosted
+  Apple Silicon runner with the `container` CLI, Python ≥ 3.11, and coverage
+  on the launchd service's PATH ([`README.md:78`](../README.md)). If you end
+  up standing up a cloud Mac for install testing, it doubles as that runner.
+
+## Recommendation
+
+Default to a **disposable Tart VM** — it's the only option that wipes the
+*entire* footprint (including the Apple Container system service that a user
+deletion leaves behind), it's a real boundary, and the spin-up/tear-down
+loop is a two-command `tart clone` / `tart delete`. Confirm your chip first:
+on **M3/M4** it tests install *and* runtime end-to-end; on **M1/M2** it still
+cleanly tests `install.sh` + `doctor`'s Python/config path, and you fall back
+to a **throwaway `sysadminctl` admin user** for live-backend testing —
+accepting that it's a hygiene boundary and that you'll manually uninstall the
+Apple Container runtime / Homebrew between runs to get back to truly clean.
+
+There is no third, lighter-weight "in-place boundary without a user" that
+actually delivers a clean, wipeable macOS — the VM *is* that answer, and it's
+the better one.
+
+## Harness
+
+The throwaway-user loop is scripted in
+[`scripts/macos-install-test.sh`](../../scripts/macos-install-test.sh):
+`up` creates the account, `run` pipes *this checkout's* `install.sh` into it
+headlessly (so a PR is verifiable before it lands) and lets the installer run
+`doctor`, `down` deletes the account and its home (the full reset), and
+`deep-reset` additionally uninstalls the host `container` runtime. It leans on
+the footprint analysis above — the reset is just user deletion because
+everything `install.sh` writes is user-home-local.
+
+`test` chains `up → run → status → down` into the one-shot cycle you normally
+want:
+
+```sh
+sudo ./scripts/macos-install-test.sh test
+```
+
+It refuses to start against an existing account (a reused home is not a clean
+install), and it tears the account down from an `EXIT`/`INT` trap armed the
+moment the account exists, so a failed or Ctrl-C'd run still leaves the machine
+clean. Its verdict is deliberately stricter than the installer's own: note that
+`install.sh` exits **0** when it finishes but `doctor` reports unmet
+prerequisites, so "the installer succeeded" is not the assertion — `test` fails
+if the install fails, if `bot-bottle` never reached the new user's `PATH`, or if
+`doctor` is unhappy. `BB_TEST_KEEP=1` skips the teardown to poke at a failure.
+
+### What a fresh account actually inherits
+
+Expect the first honest run on a developer Mac to fail at the *Python* gate,
+and expect that to be correct. A new account's `PATH` is just `/etc/paths`
+(`/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin`),
+which notably does **not** include `/opt/homebrew/bin`. Homebrew's `shellenv`
+line lives in the *installing* user's `~/.zprofile` and is not inherited, so a
+throwaway user resolves `python3` to `/usr/bin/python3` — the Command Line
+Tools stub, still **3.9.6** on macOS 26 — and `install.sh` correctly dies on its
+`3.11+` requirement. Your own shell resolving `python3` to a 3.14 Homebrew
+build says nothing about what a new user sees; that gap is exactly what this
+harness exists to expose.

+#!/usr/bin/env bash
+# Clean-install test harness for the macOS (Apple `container`) path.
+#
+# Exercises install.sh the way a brand-new user would, inside a throwaway
+# macOS account you create and delete from the CLI. install.sh's entire
+# footprint is user-home-local — the pipx venv under ~/.local, or the private
+# venv at ~/.bot-bottle/venv plus a ~/.local/bin symlink, and the ~/.bot-bottle
+# config dir. It writes no shell-profile PATH line, and never installs the
+# backend (see
+# the header of install.sh), so deleting the user is a complete,
+# deterministic reset of everything the installer touched. The Apple
+# `container` runtime is a HOST prerequisite installed once and kept;
+# `deep-reset` is the rare escape hatch that also removes it.
+#
+# Why a throwaway user and not a disposable VM: bot-bottle's default macOS
+# backend is Apple `container`, which runs each container in its own
+# Virtualization.framework microVM. Running that backend inside a macOS
+# guest VM needs nested virtualization, which Apple gates to M3+ silicon.
+# On M1/M2 a separate user account is the only way to get a clean $HOME
+# while still reaching the real host backend. Full rationale in
+# docs/research/testing-clean-install-on-macos.md.
+#
+# Usage:
+#   sudo ./scripts/macos-install-test.sh test        # up -> run -> status -> down
+#   sudo ./scripts/macos-install-test.sh up          # create the throwaway user
+#   sudo ./scripts/macos-install-test.sh run         # run install.sh (+doctor) as it
+#        ./scripts/macos-install-test.sh status      # user present? backend ready?
+#   sudo ./scripts/macos-install-test.sh down        # delete user + home (the reset)
+#   sudo ./scripts/macos-install-test.sh deep-reset  # ALSO uninstall host `container`
+#
+# `test` is the one-shot clean cycle and the command you normally want: it
+# refuses to start if the account already exists (a reused home is not a clean
+# install), and it tears the account down on the way out however it exits, so
+# a failed run never leaves an orphan behind. It exits non-zero if the install
+# fails, if `bot-bottle` is missing from the new user's PATH, or if `doctor`
+# reports unmet prerequisites — note install.sh itself exits 0 in that last
+# case, so `test` is a stricter gate than running the installer by hand.
+#
+# Config via env:
+#   BB_TEST_USER         account short name             (default: bbtest)
+#   BB_TEST_FULLNAME     account full name              (default: "bot-bottle install test")
+#   BB_TEST_ADMIN        1=admin (reach container svc), 0=standard  (default: 1)
+#   BB_TEST_INSTALL_URL  curl this install.sh instead of piping the local checkout
+#   BB_TEST_KEEP         1=`test` skips its teardown, to poke at a failure
+#   BOT_BOTTLE_INSTALL_SPEC   passed through to install.sh (pip / git spec)
+#
+# Notes:
+#   * Run from a normally-booted admin session. Grant Terminal *Full Disk
+#     Access* (System Settings -> Privacy & Security) or `down` half-fails
+#     with error -14120 and leaves an orphaned account.
+#   * `sysadminctl` always exits 0 even on failure, so `up`/`down` verify
+#     the result with `dscl` and fail loudly on a mismatch.
+#   * The account is created without a password: `run` drives it headlessly
+#     via `sudo -u`, which never needs the target's password. The account
+#     cannot GUI-login, which this harness does not require.
+#   * `run` covers the installer + `bot-bottle doctor`. Actually launching a
+#     bottle from the throwaway user may need a full launchd user session
+#     (`launchctl asuser`); on M1/M2 the backend can't run under nested virt
+#     anyway, so this harness stops at install + doctor.
