 > **NixOS:** enable `virtualisation.docker`, ensure the KVM module is loaded (`boot.kernelModules = [ "kvm-intel" ];` or `kvm-amd`), and add your user to the `kvm` and `docker` groups. For the network pool, consume the flake module — `imports = [ inputs.bot-bottle.nixosModules.firecracker-netpool ]; services.bot-bottle-firecracker = { enable = true; owner = "you"; };` — then `nixos-rebuild switch` (imperative nft/TAP rules don't survive a rebuild; channel users can `imports = [ <bot-bottle>/nix/firecracker-netpool.nix ]`). `firecracker` isn't in nixpkgs by default as a user binary — install the release binary (pin the version) and put it on `PATH`.
 
-> **CI:** the coverage gate (`.gitea/workflows/test.yml` → `coverage` job) runs on a self-hosted runner labelled `kvm`, because the Firecracker backend's VM/SSH orchestration is exercised only by the integration suite, which needs `/dev/kvm` + the provisioned pool (a container runner would skip it and read as uncovered). Provision that runner exactly like a normal Firecracker host — `firecracker` on `PATH`, `/dev/kvm`, the cached guest kernel + static dropbear, and the pool installed as the persistent systemd unit — then register it with the `kvm` label. A Docker-capable hosted job builds the candidate once; KVM tests boot those exact bytes, and a successful main run publishes them. The unit/lint jobs still run on `ubuntu-latest`.

-So the agent never learns the address. It is given a stable *name*

-Unlike `environ`, that is a file — it can be rewritten inside a container that
-is already running, so a gateway that comes back at a new address is picked up
-by live bottles instead of orphaning them.

-Apple Container 1.0 offers no container-name DNS on a user network (the only
-nameserver an agent sees is vmnet's, which does not know container names) and

-container starts.

-# PRD prd-new: Non-blocking supervise (async approval + proposal polling)
-
-- **Status:** Draft
-- **Author:** didericis
-- **Created:** 2026-07-18
-- **Issue:** #412
-
-## Summary
-
-The per-bottle supervise MCP server (`bot_bottle/supervise_server.py`)
-answers `tools/call` **synchronously**: it queues the agent's proposal and
-blocks the tool call polling for the operator's decision. On timeout it
-returns `status: pending` and leaves the proposal queued — but it hands the
-agent **no proposal id** and offers **no way to poll a specific pending
-proposal**, so the only way to learn the outcome is to re-propose (a
-duplicate).
-
-This PRD makes the MCP flow non-blocking and pollable, so an approval can
-happen out-of-band (a human taking minutes-to-hours in a review console)
-without holding an HTTP request open or wedging the agent:
-
-1. Include the `proposal_id` in the `pending` response.
-2. Add a `check-proposal` MCP tool: a non-blocking status lookup by
-   proposal id.
-3. Keep the short synchronous grace window for the common "operator is
-   right there" fast path.
-
-## Problem
-
-`handle_tools_call` → `_sv.wait_for_response(...)` blocks up to
-`SUPERVISE_RESPONSE_TIMEOUT_SECONDS` (default 30s). Two problems follow:
-
-- **Human latency ≠ tool-call latency.** A real review — rendered diff,
-  RBAC routing to an approver, someone tapping approve on their phone — is
-  minutes-to-hours. Holding the MCP request open that long is fragile
-  (proxy/keepalive timeouts, the mitmproxy egress hop, and the agent
-  harness's own tool-call timeout, which a long block can trip and stall
-  the whole turn).
-- **No resume path.** The pending fallback already exists, but without a
-  proposal id and a poll tool the agent can't reconnect to that specific
-  decision — it re-proposes, duplicating the queue entry.
-
-This is also the precondition for the planned web-console human-review
-flow (RBAC, audit retention, mobile) — see issue #412.
-
-**Safety note:** the MCP tools only *propose* policy changes; enforcement
-stays at the egress proxy and the git-gate. Returning early on `pending`
-therefore opens no hole — the agent still cannot egress or push anything
-unapproved.
-
-## Goals / success criteria
-
-- A `pending` MCP response carries the `proposal_id`.
-- An agent can call `check-proposal(proposal_id)` and get the current
-  state (`pending` | `approved` | `modified` | `rejected`) **without
-  blocking** and **without creating a new proposal**.
-- The synchronous fast path (operator approves within the grace window) is
-  unchanged: the first `tools/call` still returns the decision directly.
-- No change to enforcement, attribution (source-IP → bottle), or the
-  operator-side queue/response schema.
-
-## Non-goals
-
-- The git-gate `pre-receive` path (it is synchronous by nature and cannot
-  poll — its async variant is reject-fast + re-push; tracked as a
-  follow-up).
-- Backpressure / in-flight-proposal caps.
-- MCP server→client notifications (event-driven resume).
-- Any web-console UI (this PRD is the protocol groundwork it needs).
-
-## Design
-
-### `pending` response carries the id
-
-`handle_tools_call`'s timeout branch formats the pending text with the
-`proposal.id` and a pointer to `check-proposal`, so the agent knows what to
-poll.
-
-### `check-proposal` tool
-
-A new read-only MCP tool (`TOOL_CHECK_PROPOSAL = "check-proposal"`),
-attributed to the calling bottle by source IP exactly like the proposal
-tools. Input: `{ "proposal_id": string }`. Behavior:
-
-1. `read_response(slug, id)` →
-   - **found**: archive the proposal (same terminal step the synchronous
-     path takes) and return the decision via `format_response_text`;
-     `isError` iff rejected.
-2. **not found** → `read_proposal(slug, id)` →
-   - **found**: still queued → return `status: pending`.
-   - **not found**: unknown id, or already resolved-and-archived (e.g. a
-     second poll) → return `status: unknown`, `isError: true`.
-
-Both lookups already raise `FileNotFoundError` when absent
-(`queue_store.py`), so the handler needs no new store methods. `check-`
-`proposal` is the only path (besides the synchronous response) that
-archives, so a proposal that times out to `pending` stays visible to the
-operator until it is decided and then polled.
-
-### Grace window
-
-Left at the existing 30s default (`SUPERVISE_RESPONSE_TIMEOUT_SECONDS`),
-which doubles as the instant-approve fast path. Tuning it down is an
-operator setting, not a code change; noted for the console rollout.
-
-## Implementation chunks
-
-1. **(this PR)** `TOOL_CHECK_PROPOSAL` constant; `check-proposal` tool
-   definition + `handle_check_proposal`; dispatch wiring; `proposal_id` in
-   the pending text; unit tests. Files: `bot_bottle/supervise_types.py`,
-   `bot_bottle/supervise.py` (re-export), `bot_bottle/supervise_server.py`,
-   `tests/unit/test_supervise_server.py`.
-2. **(follow-up)** git-gate `pre-receive` reject-fast + re-push.
-3. **(follow-up)** per-bottle in-flight-proposal backpressure cap.
-4. **(follow-up)** MCP notifications for event-driven resume; web-console
-   review flow (RBAC, audit retention) on top.
-
-## Open questions
-
-- Should a resolved-but-unpolled proposal auto-archive after some TTL, or
-  only on poll? (Leaning: only on poll, so a decision is never lost to a
-  reaper before the agent sees it.)
-- Does the agent harness need an explicit "you have a pending proposal"
-  nudge, or is returning `pending` from the original call enough? (Deferred
-  to the notifications chunk.)

 # Landscape: AI-agent sandbox tools
 
-Survey of AI-agent sandbox and containment projects — including local
-coding-agent wrappers, agent-agnostic runtimes, hosted platforms, and
-governance layers — contrasted with bot-bottle's design. The original
-Claude-Code-specific containerizer survey was folded into this note on
-2026-07-20 so there is one landscape and one positioning verdict.
+A broader survey than [`landscape-containerized-claude.md`](landscape-containerized-claude.md),
+which focused on Claude-Code-specific containerizers. This one covers
+general AI-agent sandbox / containment projects — some Claude-specific,
+some agent-agnostic, some hosted SaaS — and contrasts them with
+bot-bottle's design.
 
-Research conducted 2026-05-11. CubeSandbox added 2026-07-18 (see its
-per-project note and the addendum at the end). Also updated 2026-07-18:
-bot-bottle no longer uses **pipelock** — outbound DLP is now bot-bottle's
-own (deliberately simple) egress scanner (a mitmproxy addon with custom
-detectors, PRD 0017 / 0052), and git-push secret scanning is handled by
-**gitleaks** in the git-gate. "pipelock" below has been replaced with the
-current mechanism; it survives only in older PRDs as history.
-
-Updated again 2026-07-18: six additional tools added (Cleanroom,
-container-use, Docker sbx, Anthropic srt, Microsoft AGT, Open Agent
-Passport); an **Agent-tailored policy** row added to the comparison table;
-a separate Governance layers section added for AGT and OAP. See the
-second addendum at the end.
-
-Updated 2026-07-20: the borrowable-ideas status was reconciled with the
-current implementation. In-flight credential injection and the microVM
-backends have shipped, while per-use SSH confirmation was superseded by
-keeping git credentials out of the agent entirely.
-
-Also updated 2026-07-20: **E2B and Daytona added as first-class entries.**
-Earlier revisions mentioned E2B only as the API and lifecycle model that
-CubeSandbox implements, and omitted Daytona entirely. That was a survey gap,
-not a principled scope exclusion: both are major hosted sandbox platforms and
-belong in this landscape even though they target platform builders rather than
-bot-bottle's local single-operator workflow.

   single-user, thin wrappers over an existing OS primitive
   (`sandbox-exec`, Podman + Landlock).

+The microVM cluster (matchlock, smolmachines, boxlite, microsandbox) is
+the most relevant for the v2 isolation discussion in
 [`stronger-isolation-alternatives.md`](stronger-isolation-alternatives.md):
 libkrun and Apple's Virtualization.framework have made local microVMs
-ergonomic enough that microVMs are **now bot-bottle's default backend**

-only as a legacy fallback for CI / hosts without KVM or Apple Container.
-That discussion has since shipped, not just been theorized.

-- **License**: Apache 2.0 (~12.4k stars); commercial hosted service with
-  self-hosting/BYOC support.
-- **Isolation**: Firecracker microVM per sandbox.
-- **Locality**: Cloud-hosted by default; self-hosting uses Terraform on AWS or
-  GCP (with other targets documented as works in progress).
-- **Agent integration**: LLM-agnostic Python and JavaScript/TypeScript SDKs;
-  code-interpreter and desktop-sandbox products. Platform primitive rather
-  than a coding-agent wrapper.

-  supports internet on/off, outbound allow/deny rules, and a custom egress
-  proxy.
-- **Network policy**: Configurable per sandbox, but not documented as

-  not private at the OS level. No built-in in-flight application-credential
-  injection is documented.

-  retained indefinitely.

-
-### Daytona *(added 2026-07-20)*
-
-- **Source**: https://github.com/daytonaio/daytona ;
-  https://www.daytona.io/docs/
-- **License**: Current production platform is proprietary. The former AGPL
-  repository remains public but is no longer maintained after Daytona moved
-  production development closed-source in June 2026.
-- **Isolation**: Hosted container sandboxes by default, with separate Linux
-  and Windows VM sandbox classes for dedicated-OS workloads. Each sandbox has
-  its own filesystem and network stack; VM-only features include memory
-  pause/resume and forking.
-- **Locality**: Hosted multi-tenant service, with dedicated/custom regions and
-  customer runners available.
-- **Agent integration**: LLM/framework-agnostic SDKs (Python, TypeScript, Go,
-  Ruby, Java), API, and CLI; official agent-framework guides. Platform
-  primitive rather than a local coding-agent wrapper.
-- **Config**: Programmatic per-sandbox image/snapshot, resources, lifecycle,
-  firewall, and secrets.
-- **Network policy**: Per-sandbox IPv4/domain allowlists and block-all mode,
-  subordinate to organization/tier policy. Full internet access is the
-  default on higher tiers, so it is configurable rather than uniformly
-  default-deny.
-- **Credentials**: First-class secret manager with the same phantom-token
-  pattern as bot-bottle: the sandbox environment gets an opaque placeholder,
-  an HTTPS proxy substitutes the real secret in headers only for allowed
-  hosts, and responses are scrubbed back to the placeholder.
-- **Persistence**: Persistent filesystem for stopped container sandboxes;
-  memory + filesystem pause/resume for VM sandboxes; snapshots and configurable
-  auto-stop.

-  hosted TypeScript platform primitive; application authentication,
-  authorization, and credential-proxy patterns remain the integrator's job.
-
-Both belong to the same “build your agent platform on this runtime” category as
-E2B and Daytona. They were named but not analyzed in depth by the original

-- **Source**: https://github.com/TencentCloud/CubeSandbox ;
-  HN launch https://news.ycombinator.com/item?id=47863430
-- **License**: Apache 2.0 (~10.4k stars). By Tencent Cloud; described as
-  "battle-tested, production-ready" infra already running in Tencent
-  Cloud. Rust / Go / C.
-- **Isolation**: MicroVMs via RustVMM + KVM — "each sandbox gets its own
-  Guest OS kernel, no Docker shared-kernel escapes." Hardware-level
-  isolation, dedicated kernel per instance.
-- **Locality**: Self-hosted, but **server/cluster-oriented**, not a
-  single-user local CLI. Deploy guides target PVM cloud VMs, bare metal,
-  and dev. A single 96-vCPU host is claimed to run 2,000+ concurrent
-  sandboxes.
-- **Agent integration**: **Drop-in E2B SDK replacement** (single env-var
-  change) — the headline compatibility claim. OpenClaw assistant
-  integration; general LLM-code execution. Aimed at platform builders,
-  not one developer's laptop.
-- **Config**: Programmatic via the E2B-compatible SDK. No declarative
-  manifest.
-- **Network policy**: This is the striking part — **domain allowlists,
-  instant block on unauthorized egress, full audit logs, per-sandbox
-  traffic tokens, policy-routing egress**, enforced by an eBPF-based
-  virtual switch giving kernel-level network isolation. Closest match yet
-  to bot-bottle's own default-deny + per-bottle allowlist egress model.
-- **Credentials**: **Credential vault** — agents call external APIs / LLMs
-  while "keys never enter the sandbox, model context, or logs." Same
-  in-flight-injection idea as matchlock, but productized as a vault.
-- **Performance**: <60ms cold start (claimed 2.5–50× faster than
-  alternatives), <5MB memory per instance; millisecond snapshot rollback
-  is upcoming.
-- **Maturity**: Open-sourced July 2026 off production Tencent Cloud use;
-  most-starred project in this set (~10.4k).
-
-### Cleanroom *(added 2026-07-18)*
-- **Source**: https://github.com/buildkite/cleanroom
-- **License**: Apache 2.0
-- **Isolation**: MicroVM — Firecracker on Linux, Virtualization.framework
-  on macOS. Digest-pinned OCI images.
-- **Locality**: Self-hosted server (CI-oriented).
-- **Agent integration**: Generic process sandbox; CI-first, not a
-  Claude/agent wrapper.
-- **Config**: `cleanroom.yaml` in the repo being sandboxed defines egress
-  rules, resources, and network policy. Cleanroom resolves this from the
-  commit being run.
-- **Network policy**: Default-deny + per-repo hostname allowlist (resolved
-  from DNS answers + destination IP:port). Co-hosted services on the same
-  IP:port are not distinguished. OIDC-backed auth for remote servers.
-- **Credentials**: Host-side only; not injected in-flight but not present
-  in the VM.
-- **Notable**: Policy lives in the *repo being sandboxed*, not in an
-  agent-role definition — closer to per-repo scoping than per-role.
-  Supports Docker-inside-sandbox (`services.docker.required: true`), OIDC
-  authorization, suspend/resume lifecycle.
-- **Maturity**: Active Buildkite product.
-
-### container-use *(added 2026-07-18)*
-- **Source**: https://github.com/dagger/container-use
-- **License**: Apache 2.0
-- **Isolation**: Docker container per agent + git worktree per agent.
-  Containers share the host kernel; stronger than bare host but weaker
-  than microVM.
-- **Locality**: Local.
-- **Agent integration**: MCP stdio server — Claude Code, Cursor, Windsurf.
-  `claude mcp add container-use -- container-use stdio`.
-- **Config**: None for security policy. Environments are provisioned on
-  demand; no allowlist or credential config.
-- **Network policy**: Not addressed.
-- **Notable**: Per-agent git branches (`container-use/<env_name>`);
-  parallel agents without filesystem conflict; real-time log visibility
-  and terminal attach for intervention; git-based review workflow.
-  Oriented toward parallel development safety, not security containment.
-- **Maturity**: Early development, active.
-
-### Docker sbx *(added 2026-07-18)*
-- **Source**: Docker proprietary (`sbx` CLI, separate from `docker`).
-- **License**: Proprietary.
-- **Isolation**: MicroVM (Docker's own implementation) — each session gets
-  its own kernel, Docker daemon inside the VM, and filesystem.
-- **Locality**: Local (macOS and Windows; does not require Docker Desktop).
-- **Agent integration**: Explicit wrapper — Claude Code, Codex, Gemini
-  CLI, Copilot CLI, Kiro. Launches agent inside the VM with
-  `--dangerously-skip-permissions` by default.
-- **Config**: Open / Balanced / Locked Down network presets at launch. No
-  per-role manifest.
-- **Network policy**: Default-deny; preset levels control strictness. TUI
-  dashboard shows a live log of every outbound connection (allowed and
-  blocked) with point-and-click allow/block for hosts.
-- **Credentials**: OS keychain + host-side proxy injection — API keys
-  never enter the VM.
-- **Notable**: Best DX among microVM tools (one command, works like native
-  yolo Claude but inside a VM); branch mode creates a git worktree in
-  `.sbx/`. Network policy is preset-based, not role-declarative.
-- **Maturity**: GA 2026.
-
-### Anthropic srt *(added 2026-07-18)*
-- **Source**: https://github.com/anthropic-experimental/sandbox-runtime
-  (`@anthropic-ai/sandbox-runtime` on npm, `sandbox-runtime` on PyPI)
-- **License**: Apache 2.0 (experimental).
-- **Isolation**: OS-level only — Seatbelt (`sandbox-exec`) on macOS,
-  bubblewrap on Linux, WFP (Windows Filtering Platform) account-fenced on
-  Windows. **No container or VM.** Lowest overhead in the set.
-- **Locality**: Local.
-- **Agent integration**: Claude Code's sandboxed bash tool uses this
-  internally. Can wrap any arbitrary process (`srt <command>`). Cloud
-  Claude Code sessions use full microVMs instead.
-- **Config**: Programmatic per-invocation — allow/deny path lists for
-  filesystem; allow/denylist for network (HTTP proxy + SOCKS5).
-- **Network policy**: Proxy-based filtering (HTTP + SOCKS5); domain
-  allowlist/denylist enforced at proxy layer. Custom proxy supported
-  (e.g. mitmproxy for inspection + audit). Processes that ignore proxy
-  env vars may bypass filtering on some platforms.
-- **Notable**: Cross-platform (macOS/Linux/Windows); wraps any process,
-  not just agents; no role/manifest concept. Annotated as a research
-  preview — APIs may change.
-- **Maturity**: Early research preview.

-- **Network policy**: Per-project firewall allowlists.

-### Trail of Bits claude-code-devcontainer
-
-- **Source**: https://github.com/trailofbits/claude-code-devcontainer
-- **Isolation**: A Docker devcontainer that exposes only project files and is
-  designed to run Claude Code with `bypassPermissions` for security audits and
-  untrusted-code review.
-- **Difference**: a hardened, reusable environment definition rather than an
-  agent launcher or fleet. It has no named-role manifest, per-role credential
-  custody, supervision plane, or multi-backend abstraction.
-
-### Smaller wrappers and official templates
-
-Projects such as `arezi/claude-sandbox`, `nkrefman/claude-sandbox`, and
-`VishalJ99/claude-docker`, plus Docker/Anthropic devcontainer templates, prove
-there is steady demand for “Claude in a container.” They are deliberately
-small launch/build configurations. They compete on setup simplicity, not on
-role-aware policy, credential custody, persistent supervision, or a fleet
-model, and are better treated as a product category than as individual rows.
-
-### SuperHQ
-
-- **Source**: https://superhq.ai/
-- **Isolation**: Apple-Silicon desktop application using local microVMs via
-  Virtualization.framework/libkrun-era components.
-- **Agent integration**: Claude Code, Codex, and Pi in a GUI, with mobile
-  remote access.
-- **Credentials and review**: host-side auth gateway injects credentials on
-  the wire; a temporary overlay stages writes for diff-and-accept review.
-- **Closest overlap**: local microVM isolation, multi-provider launching, and
-  credential custody for security-minded individual developers.
-- **Difference**: GUI desktop product on Apple Silicon rather than a
-  cross-platform declarative CLI/fleet layer. The July 2026 snapshot in the
-  original survey recorded a user request for per-run tool-call and network
-  audit logging; treat that as point-in-time rather than a permanent gap.
-
-## Credential gateway without isolation
-
-### OneCLI
-
-[OneCLI](https://onecli.sh/) is a framework-agnostic identity gateway rather
-than a sandbox. Its phantom-token design gives the agent a placeholder and
-substitutes the encrypted real credential at the network layer. It therefore
-matches bot-bottle closely on secret custody, and is more portable because it
-can sit in front of agents launched by anything, but it supplies no container
-or VM boundary, filesystem isolation, role manifest, or egress-content DLP.
-
-The positioning consequence from the earlier survey still holds: secret
-custody alone is not unique. bot-bottle's relevant combination is local
-isolation + default-deny egress + payload DLP + declarative roles + credential
-custody. OneCLI's managed tier also places custody with a third party, whereas
-bot-bottle keeps it within operator-controlled infrastructure. See
-[`agent-credential-proxy-landscape.md`](agent-credential-proxy-landscape.md)
-for the detailed build-versus-adopt analysis.
-
-## Governance / pre-action authorization layers
-
-These two tools don't provide VM or filesystem isolation; they intercept
-tool calls before execution and evaluate them against a per-agent
-declarative policy. They are the closest competitors on **agent-tailored
-policy** and complement isolation sandboxes rather than substituting for
-them.

-- **Source**: https://github.com/microsoft/agent-governance-toolkit
-- **License**: MIT (~3.3k stars, open-sourced April 2, 2026).
-- **Isolation**: None (OS/VM). Execution rings (0–3, inspired by CPU
-  privilege levels) control what an agent can do at the framework layer.
-  MCP security gateway treats MCP traffic as an untrusted boundary.
-- **Locality**: Embedded in the agent framework (Python, TypeScript, .NET,
-  Rust, Go; 20+ framework adapters).
-- **Agent integration**: Framework-agnostic. Plugs into Semantic Kernel,
-  AutoGen, and others as a middleware layer.
-- **Config**: YAML policy per agent — tools can be `allowed`, `denied`,
-  `sandboxed`, or routed through an `approval` step. Every action passes
-  through a governance gate checking: agent DID, trust score, risk tier,
-  requested tool, action type, and policy rules.
-- **Network policy**: Not directly — operates at tool-call level.
-- **Credentials**: Per-agent DID (Ed25519 decentralized identifier); agent
-  does not borrow a human's credentials.
-- **Notable**: Dynamic trust score (0–1,000, behavioral decay) —
-  privilege follows observed behaviour, not just provisioning. Covers all
-  10 OWASP Agentic Top 10 risks. Kill switch + SLO monitoring. Sub-ms
-  policy enforcement.

 ## What's closest, what's different
 
 **Closest in design and scope.** agent-safehouse and litterbox sit
 nearest bot-bottle: local, single-user, thin wrappers over an
 existing OS primitive, low-dep. The split is the isolation primitive —
-bot-bottle now defaults to a VM per bottle (Firecracker microVM on KVM
-Linux, Apple Container on macOS) with its own DLP-scanning egress proxy,
-keeping Docker only as a legacy fallback; agent-safehouse uses
-`sandbox-exec`; litterbox uses Podman + Landlock. matchlock and
-smolmachines are close on *both* the policy side (default-deny net,
-per-host allowlist) and — now that bot-bottle has moved off
-containers-by-default — the microVM isolation primitive. Note: Apple
-Container 1.0 stable shipped June 9 2026 (frozen CLI and APIs), which
-makes the macOS backend stable surface area rather than a moving target.
-
-**New closest on agent-tailored policy.** Two governance tools are the
-direct competitors on the "coarse-grained sandbox" axis. **tilde.run**
-has had per-agent DSL RBAC since its launch (though it's hosted SaaS).
-**Microsoft AGT** is the most serious new entrant: per-agent DID
-identity, YAML policy that can allow/deny/sandbox/approve individual tool
-calls per agent, and a dynamic behavioural trust score. It operates at
-the framework tool-call layer, not the network layer — so it's
-complementary to bot-bottle's network/filesystem isolation rather than a
-direct substitute, but on the "does this sandbox know what this agent is
-for?" question it is the most complete answer in the field. OAP's
-pre-action hook pattern achieves similar goals with cryptographic audit
-and a 0% adversarial-attack success rate under a restrictive policy.
-
-**New closest on DX.** **Docker sbx** is the first tool in this set that
-matches bot-bottle on the "one command, dangerously-skip-permissions safe
-by default" DX bar, at microVM isolation strength, with host-side
-credential injection. It is proprietary, preset-based (not role-
-declarative), and cloud-agent-specific, but it directly competes on the
-UX proposition. agent-safehouse was the previous DX peer; Docker sbx
-materially raises the bar.
-
-**New closest on repo-scoped policy.** **Cleanroom** (Buildkite) is the
-first tool to combine microVM isolation with a declarative egress policy
-file — though the policy lives in the repo being sandboxed
-(`cleanroom.yaml`), not in an agent-role manifest. That makes it per-
-repo rather than per-role: the same Cleanroom config applies to any
-agent running in that repo. The distinction matters for bot-bottle's
-use case (one developer running multiple agent *roles* with different
-egress footprints), but for CI/CD use cases Cleanroom is a direct
-alternative.
+bot-bottle uses Docker + pipelock egress (plus gVisor where
+available); agent-safehouse uses `sandbox-exec`; litterbox uses Podman +
+Landlock. matchlock and smolmachines are spiritually close on the
+*policy* side (default-deny net, per-host allowlist) but use microVMs
+instead of containers.
 
 **Solving a different problem.** tilde.run is hosted SaaS for team /
 production agent pipelines with data-versioned rollback — explicitly
-opposite to bot-bottle's "infrastructure I control" goal. E2B and Daytona
-are hosted sandbox platforms, while boxlite, microsandbox, and CubeSandbox
-are infrastructure libraries/services aimed at platform builders embedding
-sandboxes into agent frameworks; they
-would be a *backend* bot-bottle could call, not a competitor to its
-manifest layer. endo-familiar is in a different paradigm entirely:
-capability passing rather than kernel boundaries.

 ## Borrowable ideas
 
-### Already shipped or otherwise addressed
-
-- Default-deny egress with a per-agent allowlist (own egress scanner).
+What bot-bottle already has that the survey suggested as
+differentiators:
+- Default-deny egress with a per-agent allowlist (pipelock).
 - DLP scanning of outbound traffic.
 - Bottle / agent split (manifest layer above the isolation primitive).
 - gVisor auto-detection on Linux.
-- **In-flight secret injection** (suggested by matchlock) — **shipped.**
-  Real provider and git-host tokens are held outside the agent and injected
-  by the egress gateway on matching routes. The agent receives only proxy
-  URLs and, where a client requires a credential-shaped value, a placeholder;
-  `GITEA_TOKEN` and equivalent real tokens do not appear in the agent's
-  environment.
-- **MicroVM backend** — **shipped.** MicroVMs are now the default:
-  Firecracker on KVM Linux and Apple Container on macOS. Docker is the legacy
-  fallback.
-- **Per-use SSH key confirmation** (suggested by litterbox) — **addressed by
-  stronger credential custody instead.** The agent does not hold the upstream
-  git SSH key or an SSH-agent socket: git-gate holds the credential and gates
-  git operations. A confirmation wrapper inside the agent would therefore
-  protect a credential that is no longer there. Operator approval at the gate
-  remains the appropriate control point for any future per-use confirmation.
 
-### Still worth considering
+Ideas worth considering, without abandoning the Python-stdlib-first / local-Docker
+stance:
 
-- **Live network activity in the supervisor TUI** (from Docker sbx): show
-  allowed and blocked connections and let the operator propose policy changes
-  from the existing supervision surface.
-- **Tamper-evident audit records** (from OAP): sign and hash-chain egress and
-  supervision decisions for compliance-sensitive deployments.
-- **Behaviour-informed policy downgrade** (from Microsoft AGT): use repeated
-  DLP alerts or supervision holds as a signal to narrow policy or request
-  closer review. This needs a carefully specified trust model before it can be
-  more than a heuristic.
+1. **Per-use SSH key confirmation** (from litterbox). Even with
+   KnownHostKey pinning and pipelock egress, a wrapper SSH agent that
+   prompts on each key use (e.g. via `osascript` / `notify-send`) would
+   catch an agent doing something off-policy with a key it legitimately
+   holds. Pure-stdlib, no new deps.
+2. **In-flight secret injection** (from matchlock). Pipelock already
+   does egress allowlisting and DLP; teaching it to *inject* tokens at
+   proxy time so e.g. `GITEA_TOKEN` never appears in the container's
+   env would close the "agent reads its own env and exfiltrates" path.
+   Fits the existing pipelock architecture.
+3. **MicroVM backend as an opt-in bottle type** — already on the radar
+   in `stronger-isolation-alternatives.md`. microsandbox, smolmachines,
+   and matchlock all show that libkrun + Apple's
+   Virtualization.framework is ergonomic enough that a
+   `"runtime": "microvm"` field on a bottle is plausible without a heavy
+   stack.
 
 Not worth borrowing: the SDK-first programmatic API style of boxlite /
 microsandbox (cuts against the declarative-manifest stance), and the
 hosted-SaaS dashboard model of tilde.run (cuts against the
 "infrastructure I control" goal).
 
-## Publishing and positioning verdict
-
-Publishing remains worthwhile, but the defensible claim is the combination,
-not any single primitive. Credential custody is matched by OneCLI, matchlock,
-Daytona, Docker sbx, and CubeSandbox; local one-command isolation is matched by
-agent-safehouse and Docker sbx; hosted microVM execution is a crowded platform
-category.
-
-bot-bottle remains unusual in combining:
-
-- local, operator-controlled execution with persistent named bottles;
-- one declarative role layer across Claude Code, Codex, Pi, and provider
-  plugins;
-- composable agent/bottle manifests, skills, and system prompts;
-- Firecracker/Apple Container isolation with a Docker fallback;
-- default-deny per-role egress, payload DLP, and git-push secret scanning;
-- credentials injected outside the agent process; and
-- supervision and audit state suited to long-running parallel agents.
-
-The practical wedge is “as easy as native yolo, with declarative role policy
-and self-hosted custody,” including scoped access to private LAN/Tailnet
-services that cloud-first runtimes cannot provide without additional network
-plumbing. The main competitive risks are a local wrapper such as claudebox or
-Docker sbx growing a role-manifest layer, and GUI products such as SuperHQ
-adding equivalent policy and audit depth.

-## Addendum 2026-07-18 — CubeSandbox and the positioning read
-
-CubeSandbox (Tencent Cloud, Apache 2.0, ~10.4k stars, HN launch
-[#47863430](https://news.ycombinator.com/item?id=47863430)) is the first
-open-source, self-hostable project in this survey to combine, in one stack,
-the main primitives
-bot-bottle treated as its differentiator:
-
-- **Egress custody (connection level)** — default-deny domain allowlist
-  (L7 domain/SNI filtering), instant block on unauthorized egress,
-  per-sandbox traffic tokens, full audit logs of destinations (eBPF
-  virtual switch, "CubeVS"). This matches bot-bottle's egress scanner at
-  the *connection level*, productized — see the one thing it does **not**
-  match, below.
-- **Credential custody** — a vault where keys "never enter the sandbox,
-  model context, or logs." This is the in-flight-injection idea from
-  matchlock, but as a first-class feature, and it's exactly the
-  cross-vendor "egress audit + custody" wedge the monetization
-  positioning treats as the one defensible moat.
-- **Isolation on par with bot-bottle's current default** — a dedicated
-  guest kernel per sandbox (RustVMM/KVM). bot-bottle now defaults to the
-  same class of boundary (Firecracker microVM / Apple Container), so this
-  is parity, not an edge; CubeSandbox's remaining edge is running that
-  per-kernel isolation multi-tenant at scale on one host.
-
-The one axis CubeSandbox does **not** cover — and where bot-bottle stays
-distinctive:
-
-- **Content DLP on *authorized* channels.** CubeSandbox's egress control
-  is connection-level: it decides *whether* a destination is allowed and
-  logs it, and its vault keeps *injected* credentials out of the sandbox
-  entirely. Neither inspects the *payload* of traffic to an allowed
-  destination. So an agent that exfiltrates over a permitted channel —
-  pasting a repo's contents, an agent-derived secret, or PHI into an
-  allowed API/domain — is not caught by CubeSandbox. bot-bottle's own
-  egress DLP scanner does scan that: response + websocket content against
-  the resolved per-flow config, with per-bottle token redaction (see
-  recent egress commits). The vault
-  approach is arguably *stronger* for the specific case of pre-known
-  injected credentials (they can't leak if they were never present), but
-  it is not a substitute for content inspection of everything else.
-
-**Long-running posture — a sharper axis than raw isolation.** E2B and
-CubeSandbox are *ephemeral-per-task* by design; a long-running agent is an
-architected pattern on top, not the default. E2B: 5-minute default
-timeout, continuous runtime tier-capped (~1h Hobby / ~24h Pro), duration
-achieved via **pause/resume** (preserves filesystem + memory + processes;
-reconnect by sandbox ID via `Sandbox.connect()`; resume resets the timeout
-to 5 min; auto-pause via `on_timeout: "pause"`). CubeSandbox mirrors this
-(E2B drop-in) with first-class auto pause/resume and hundred-ms
-checkpoint/fork — and, self-hosted, sets its own timeout policy with no
-vendor tier caps. bot-bottle inverts the model: a bottle is **persistent,
-named, and supervised by default** — long-running *is* the default, not a
-session-management loop over pause/resume. smolmachines is the other
-persistent-by-default project in this set. For anyone building agents that
-run for hours/days, this posture difference matters more than the
-isolation primitive.
-
-**DX — the "run Claude yolo-style" bar.** The reason `claude
---dangerously-skip-permissions` is so widely used is DX: it's one command
-and the agent just goes. The bottle thesis is to make a *sandboxed* run
-that easy — `start <agent>` builds the image on first run and drops you
-into an interactive Claude session that already has
-`--dangerously-skip-permissions` on by default
-(`contrib/claude/agent_provider.py`), with the sandbox as the guardrail
-instead of per-action prompts. On this axis the field splits cleanly:
-- **Wrappers around the agent** (as-easy-as-native): bot-bottle and
-  **agent-safehouse** (`safehouse claude --dangerously-skip-permissions`).
-  These *are* the run-Claude experience. agent-safehouse is the real DX
-  peer — but it's macOS-only Seatbelt, single-run, and doesn't address
-  network egress; bot-bottle adds VM-grade isolation, egress DLP, and
-  persistent/parallel bottles across macOS + Linux.
-- **Libraries / services** (you build the run yourself): boxlite,
-  microsandbox, CubeSandbox, E2B, Daytona. These hand you an SDK or a cluster and
-  expect you to wire the agent in — powerful for platform builders,
-  heavyweight for "just run Claude on my laptop." microsandbox's MCP/Skills
-  angle is *sandbox-as-a-tool the agent calls*, which is the inverse of
-  wrapping the agent.
-- **In between:** litterbox (wizard + build, Linux only), smolmachines
-  (SSH into a named machine), matchlock (run a command in a VM).
-
-So DX is a genuine bot-bottle differentiator. agent-safehouse matches the
-one-command wrapper with weaker isolation and no egress story; Docker sbx now
-matches it at microVM strength but remains proprietary and preset-based. "As
-easy as native yolo, with declarative role policy" is the narrower defensible
-one-liner.
-
-Why it still doesn't collide head-on:
-
-1. **Shape.** CubeSandbox is a *multi-tenant service for platform
-   builders* (drop-in E2B replacement, SDK-driven, 2,000 sandboxes on a
-   box). bot-bottle is a *single-operator, declarative-manifest tool for
-   the infrastructure I run*. Different buyer, different ergonomics — no
-   declarative role manifest, no bottle/agent split, no "one command on my
-   laptop."
-2. **Backend, not competitor.** Like boxlite/microsandbox, CubeSandbox is
-   something bot-bottle could sit *on top of* — a `"runtime": "microvm"`
-   or `"runtime": "cubesandbox"` backend under the manifest layer — while
-   keeping the manifest, the bottle/agent split, and the local,
-   single-operator default.
-
-Why it matters anyway:
-
-- The "nobody else bundles connection-level egress allowlist + audit +
-  in-flight credential custody" line is **no longer true for the
-  primitive** — CubeSandbox ships the open-source/self-hosted combination,
-  and Daytona ships a proprietary firewall + credential-substitution variant.
-  But **content DLP on authorized channels is still not matched** (see
-  above), and neither is the *layer above* the primitive (declarative
-  manifest, cross-vendor orchestration, operator UX, the
-  phone-control/dashboard north star). Those two — outbound-payload DLP
-  and the orchestration layer — are where the defensible ground now sits;
-  the connection-level allowlist + vault mechanism, on its own, is no
-  longer differentiating. Revisit the monetization open/paid line with
-  that in mind.
-- Worth a closer look at **how** CubeSandbox does credential injection
-  and per-sandbox egress tokens (eBPF virtual switch vs. bot-bottle's
-  mitmproxy egress proxy) when hardening bot-bottle's now-shipped
-  credential-custody implementation.
-
-## Addendum 2026-07-18 (second pass) — agent-tailored policy landscape
-
-The second-pass question was: how novel is bot-bottle's per-agent,
-role-tailored sandbox relative to the expanded field?
-
-**The short answer:** on the isolation + network + role-tailoring
-combination, bot-bottle remains the only tool in this set. On
-role-tailored *policy at the tool-call level*, Microsoft AGT and OAP are
-the most complete answers, but they don't provide isolation; they
-complement rather than substitute.
-
-**The competitive picture by axis:**
-
-- *Agent-tailored egress (declarative, per-role)* — bot-bottle and
-  tilde.run. Cleanroom is per-repo, not per-role. Everyone else is
-  per-session or not addressed.
-- *Agent-tailored tool-call policy (declarative, per-agent identity)* —
-  Microsoft AGT (YAML policy + DID identity + trust score), OAP
-  (declarative policy rules + cryptographic audit). Neither provides
-  network/filesystem isolation.
-- *Composable policy (role overlays)* — bot-bottle (`extends:`). No
-  other tool surveyed supports composable role-policy inheritance.
-- *Isolation + DX (one-command safe yolo)* — bot-bottle and Docker sbx.
-  Docker sbx is proprietary, preset-based, and cloud-agent-specific;
-  it's the first DX-class competitor at microVM isolation strength.
-
-**What the HN "coarse-grained" complaint maps to:** The complaint is
-that a VM isolates the filesystem but doesn't know if the agent
-*should* be sending an email. bot-bottle's bottle/agent split is a
-structural answer to this: the bottle manifest declares exactly what
-the role can reach, and the sandbox enforces it at the network layer.
-Microsoft AGT is the most complete answer at the semantic/tool-call
-layer. The gap both leave open is *intent classification* — knowing
-whether a permitted action is consistent with the agent's actual task.
-See `hn-agent-safety-discourse-july-2026.md` for the blast-radius
-analysis.
-
-**Open ideas from new tools (also summarized above):**
-
-- **Microsoft AGT's trust-score decay** — privilege that reflects
-  observed behaviour rather than static provisioning. Applied to
-  bot-bottle: a bottle that has triggered DLP alerts or supervise holds
-  could auto-downgrade its network preset, or flag the session for
-  closer review. Fits the existing supervise-server architecture.
-- **Docker sbx's live network TUI** — real-time per-session view of
-  allowed and blocked outbound connections with point-and-click
-  allow/block. `cli.py supervise` is the right surface; adding a
-  live-connections panel would directly address the "I can't see what
-  the agent is doing" gap without any backend changes.
-- **OAP's cryptographic audit chain** — Ed25519-signed, hash-chained
-  audit records. Currently bot-bottle logs egress decisions but doesn't
-  chain them. A tamper-evident audit record per session would be useful
-  for the compliance use case the CubeSandbox positioning targets.

-# HN discourse on agent sandbox safety — June/July 2026
-
-A survey of community opinion and notable security disclosures on Hacker
-News and adjacent sources over June–July 2026. The question: what does
-the current discourse say about whether sandboxes are sufficient for
-agentic AI safety, and where does bot-bottle land against the issues
-being raised?
-
-Research conducted 2026-07-18.
-
-## Summary
-
-The past month marks a turning point in community opinion. Earlier in
-2026, the debate was mostly "which sandbox tool is best?" By June–July,
-a cascade of critical CVEs and novel attack classes has shifted the
-framing to "sandboxes are not enough — what else do you need?" The
-attacks that drove this shift are structurally distinct: most route
-through legitimate, trusted channels (Sentry issues, MCP descriptions,
-README files) rather than exploiting the isolation boundary directly.
-
-bot-bottle's architecture holds up well against the direct-escape class
-(Firecracker/Apple Container default backends, credentials never in the
-agent's env, harness entirely on the host). The remaining gap is prompt
-injection — attacker-controlled data interpreted as model instructions.
-Egress controls and prompt injection defenses are orthogonal: egress
-limits what the agent can *send out*; injection is about what it is
-*told to do*. The two don't substitute for each other. Inside a tightly-
-egressed sandbox a successful injection can't exfiltrate to unknown
-hosts, but it can still corrupt the work product, push malicious commits
-past a secret scanner, or use allowlisted channels for exfiltration.
-Those residual risks are addressed below.
-
-## The sandboxing boom sets the stage
-
-The preceding months generated a wave of sandbox tooling. A March 28
-Ask HN thread
-([#47444917](https://news.ycombinator.com/item?id=47444917)) catalogued
-the explosion: E2B, AIO Sandbox, AgentSphere, Yolobox, Exe.dev,
-AgentFence, DenoSandbox, Capsule (WASM), ERA, Vibekit, Daytona, Modal,
-Nono, and more — all launched within roughly 12 months. A parallel March
-9 thread ([#47185250](https://news.ycombinator.com/item?id=47185250))
-surveyed what developers were actually deploying: "containers or YOLO"
-dominated. The honest community mood was that most teams hadn't solved
-this and were shipping anyway.
-
-The March 12 launch of **Agent Safehouse**
-([#47301085](https://news.ycombinator.com/item?id=47301085), 823 points)
-crystallised the community framing: a zero-dep `sandbox-exec` wrapper for
-macOS that attracted the top comment *"I honestly think that sandboxing is
-currently THE major challenge that needs to be solved for the tech to fully
-realise its potential."* The creator's own framing — "no dependencies, no
-daemons, no subscription; the simplicity is the feature" — and Simon
-Willison's observation that evaluating whether a sandboxing tool works as
-intended is itself hard, both prefigure the June–July shift in tone. See
-[`agent-sandbox-landscape.md`](agent-sandbox-landscape.md) for a full
-per-project breakdown.
-
-## The June–July attack cascade
-
-Six attack patterns broke in quick succession. Together they form the
-argument that the community's framing was wrong: the threat model for
-agents isn't just "code that escapes its container" — it's also prompt
-injection, where attacker-controlled data is interpreted as model
-instructions regardless of whether any isolation boundary was crossed.
-Sections 2–4 below are all the same attack class; the "trusted channel"
-label describes the delivery vector, not a different threat.
-
-### 1. Sandbox escape CVEs (DuneSlide, CVE-2026-39861)
-
-Cato AI Labs disclosed **DuneSlide** (CVE-2026-50548/50549, CVSS 9.8),
-a pair of flaws in Cursor 2.x. CVE-2026-50548 abuses the sandbox's
-`working_directory` parameter to point writes at system files; CVE-26-50549
-exploits a symlink-resolution fallback that fails open. Both start with
-a prompt injection and end in sandbox escape — and Cato's framing was
-blunt: "each CVE defeats a different guardrail; the problem is
-structural, not a string of one-offs."
-
-Claude Code's own sandbox had a similar escape this year:
-**CVE-2026-39861** (symlink flaw). The CurXecute/MCPoison/CVE-2026-26268
-chain from Cursor added a poisoned Slack message, a swap-after-approval
-MCP config, and a Git hook as three more entry points in the same
-attack class.
-
-All patched, but the pattern holds: any application-level sandbox that
-takes attacker-influenced values as path parameters is reachable from a
-prompt injection.
-
-### 2. Prompt injection via MCP data (Agentjacking)
-
-Tenet's "Agentjacking" technique planted a fake bug report in Sentry's
-MCP output. When an agent queries Sentry to fix open issues, the
-malicious event is rendered as structured content visually
-indistinguishable from a real Sentry event, and the agent executes the
-embedded instructions with the developer's full privileges. Hit rate
-across Claude Code and Cursor: **85%**. The route is entirely through a
-legitimately-authorized MCP channel — no isolation boundary is crossed;
-the injection arrives inbound through a channel the sandbox explicitly
-trusts.
-
-The Cloud Security Alliance's summary: treat observability, bug-report,
-and integration data as **untrusted agent input**, not neutral
-development metadata.
-
-### 3. README-embedded prompt injection
-
-A July disclosure showed malicious instructions hidden in `README.md`
-— a file that receives no trust prompt and requires no elevated access.
-When asked point-blank whether the repo held hidden instructions, both
-Claude Sonnet 4.6 and GPT-5.5 said no. A payload written for Sonnet
-4.6 transferred unchanged to Sonnet 5, Opus 4.8, and GPT-5.5. The
-attack surface is every repo an agent is asked to work in.
-
-### 4. Prompt injection via MCP tool descriptions
-
-Microsoft research (June 30) showed that attacker-controlled MCP tool
-description fields can silently redirect agent behavior. The injection
-is embedded in metadata the model reads during tool selection — before
-any sandbox enforcement or egress check runs, and entirely on the
-inbound path that egress controls cannot touch.
-
-### 5. MCP STDIO command injection (10 CVEs)
-
-OX Security disclosed a systemic command injection class in Anthropic's
-MCP protocol, covering 10 CVEs across multiple coding agents. The
-Windsurf case (CVE-2026-30615): processing attacker-controlled HTML
-causes the agent to auto-register a malicious MCP STDIO server and
-execute arbitrary commands with no further user interaction.
-
-### 6. LiteLLM gateway compromise (CVE-2026-40217, CVE-2026-42271)
-
-CVE-2026-40217 exposes LiteLLM's guardrail sandbox via `exec()` with no
-source filtering. CVE-2026-42271 (exploited in the wild, added to CISA's
-KEV catalog) lets callers spawn subprocesses through MCP preview
-endpoints. The threat extends to any agent routed through a compromised
-LiteLLM proxy: the proxy can swap model responses for forged tool calls
-in transit, giving the attacker a reverse shell from the developer's
-machine.
-
-## HN community opinion clusters
-
-**"Move enforcement to the kernel, not the app"** — the Nono Show HN
-([#46849615](https://news.ycombinator.com/item?id=46849615)) and a
-kernel-sandbox thread
-([#47066574](https://news.ycombinator.com/item?id=47066574)) both argued
-that application-layer sandboxes are inherently bypassable by the code
-they're sandboxing. The academic framing, from *Red-Teaming the Agentic
-Red-Team* ([arXiv 2606.24496](https://arxiv.org/pdf/2606.24496)):
-"enforcement should occur at the OS level via the kernel refusing system
-calls that violate policy at runtime — not pre-execution argument
-validation in tool calls."
-
-**"The harness belongs outside the sandbox"** — a May thread
-([#47990675](https://news.ycombinator.com/item?id=47990675)) converged
-on clean architectural separation: harness in one VM, tool execution in
-another. Top comment: "having the harness in one VM, and tool use applied
-to user data in another, is about as safe as you can be at present."
-Several replies described a hypervisor-like policy layer — sitting outside
-both VMs — as the right long-term model.
-
-**"Sandboxes are too coarse-grained"** — a Feb thread
-([#47006445](https://news.ycombinator.com/item?id=47006445)) argued
-that VMs don't answer the real question: knowing whether an agent
-*should* be sending an email or making a transaction. "Everything's just
-in the same big box." This framing picked up traction through June–July
-as the trusted-channel attacks dominated.
-
-**"MCP's trust model is the real problem"** — the month's recurring
-theme. MCP by design gives agents access to authorized external services.
-Once a trusted channel delivers a malicious payload, filesystem sandboxing
-is irrelevant. The community call: treat all MCP tool metadata and return
-values as untrusted input subject to policy validation before ingestion,
-and disable automatic MCP server loading from untrusted repositories.
-
-## How bot-bottle addresses these issues
-
-### What it covers well
-
-**Direct sandbox escape (CVEs, container breakout)**
-
-bot-bottle's default backends are Firecracker microVM (KVM Linux) and
-Apple Container (macOS). Both run the agent in a separate VM with a
-dedicated kernel — the container-escape CVE class (Dirty Pipe, runc
-escapes, DuneSlide's path-parameter abuse) requires escaping a real
-hypervisor boundary, not just a namespace. On the legacy Docker backend,
-gVisor auto-detection provides a userspace syscall barrier for hosts where
-neither KVM nor Apple Container is available.
-
-The bot-bottle process itself runs entirely on the host, outside the VM.
-This is the "harness outside the sandbox" architecture the HN thread
-converged on as best practice. The bottle manifest, egress rules, and
-secrets never enter the agent VM.
-
-**Credential theft on sandbox escape**
-
-Even on a successful VM/container escape, the agent has nothing useful
-to steal. Credentials are injected in-flight by the gateway proxy
-(`auth.scheme` / `auth.token_ref` in the egress route config) — `printenv`
-inside the agent shows proxy URLs only. The git-gate similarly holds the
-upstream SSH credential on the host; the agent pushes through a
-gitleaks-scanned daemon that forwards clean refs upstream. An escaped
-agent gets the host filesystem, not the keys.
-
-**Orphaned-agent credential risk**
-
-bot-bottle is explicitly ephemeral: when the agent exits, `cli.py` tears
-down every gateway and both networks — nothing persists between runs. The
-agent never holds credentials, so there is nothing to orphan.
-
-**MCP config redirection / STDIO auto-registration**
-
-The trust boundary at `$HOME` means bottles live only under
-`~/.bot-bottle/bottles/` — a cloned repo cannot add egress routes or
-redirect env vars to attacker hosts (the design rationale is in
-`docs/prds/0011-per-file-md-manifest.md`). Auto-registering a malicious
-MCP STDIO server from within the agent is still sandboxed by the VM, and
-any outbound calls from that server must pass the egress allowlist and
-outbound DLP scanner.
-
-**Per-agent role tailoring (the "coarse-grained sandbox" complaint)**
-
-The Feb 2026 HN thread that argued "sandboxes are too coarse-grained"
-was pointing at a real gap: a VM isolates the filesystem but doesn't
-know whether an agent *should* be sending email or calling an external
-API. bot-bottle's bottle/agent split is a structural answer at the
-network layer — the bottle manifest declares exactly what each role can
-reach (which hosts, which paths, which HTTP methods), and the egress
-scanner enforces it. A `gitea-dev` bottle that only lists
-`gitea.dideric.is` and `api.anthropic.com` structurally cannot send
-email or reach AWS, not because the model was told not to, but because
-those routes don't exist.
-
-The `extends:` composition model means provider-level policy (the Claude
-auth route) lives in one base bottle and role-specific overlays are
-stacked on top — no duplication, and changing the base propagates to all
-derived roles.
-
-Competitive position on this axis (from `agent-sandbox-landscape.md`):
-
-| Tool | Agent-tailored policy |
-|---|---|
-| **bot-bottle** | Yes — declarative per-role manifest; `extends:` composition; egress + credentials scoped to role |
-| **tilde.run** | Yes — per-agent DSL RBAC (allow/deny/approve per action/repo/agent), but hosted SaaS |
-| **Microsoft AGT** | Yes — YAML policy + per-agent DID + trust score, but tool-call level only (no network isolation) |
-| **OAP** | Yes — declarative pre-action policy + cryptographic audit, but no isolation |
-| **Cleanroom** | Partial — per-repo `cleanroom.yaml`, not per-role |
-| **Docker sbx** | No — network presets only |
-| **Anthropic srt** | No — programmatic per-invocation |
-| **matchlock / smolmachines / microsandbox** | No |
-| **agent-safehouse** | Partial — per-agent Seatbelt profiles; no egress |
-
-Two takeaways: bot-bottle and tilde.run are the only isolation tools
-with declarative role-tailored policy; Microsoft AGT and OAP are the
-closest competitors on role-tailoring but operate at the tool-call layer
-without network/filesystem isolation — complementary, not substitutes.
-
-**Outbound exfiltration (any injection class)**
-
-Whatever triggers the agent — README injection, Agentjacking, MCP
-description poisoning — the final step in most attacks is exfiltration.
-bot-bottle's egress allowlist is default-deny with a per-bottle host
-allowlist; unknown hosts get a hard 403. Outbound DLP scanning
-(`outbound_detectors: [token_patterns, known_secrets]`) catches tokens
-and secrets in outbound bodies; the `supervise` policy (default for
-manifest routes) holds the request for operator approval rather than
-silently blocking it. Together these limit what a successful injection
-can *do* even if it succeeds at the model layer.
-
-**LiteLLM / compromised-proxy attacks**
-
-bot-bottle does not use LiteLLM. The model API route (e.g.
-`api.anthropic.com`) is an auto-injected provider route on the egress
-allowlist; the agent dials the gateway, not the model API directly.
-A compromised third-party proxy is not in the architecture.
-
-### Where it is weaker
-
-**Prompt injection**
-
-Egress controls and prompt injection defenses are orthogonal. Egress
-limits what the agent can *send out* (outbound leg); prompt injection
-is about what attacker-controlled data *tells the agent to do* (inbound
-leg). The two don't substitute for each other and must be treated
-separately.
-
-The inbound DLP scanner (`inbound_detectors: [naive_injection_detection]`)
-is the only runtime defense against injection arriving through allowlisted
-channels — Sentry MCP responses, MCP tool descriptions, README content.
-It is explicitly pattern-matching and will not catch a sufficiently
-crafted payload. There is no semantic / intent-level gate between what
-the model decides and what the agent executes.
-
-**Blast radius within the permitted scope**
-
-Inside a tightly-egressed sandbox a successful injection can't
-exfiltrate to unknown hosts, but it still has real options:
-
-- *Work product corruption.* The agent can modify, delete, or backdoor
-  files in the working directory. This is within its permitted scope;
-  egress controls have nothing to say about it.
-
-- *Malicious commits past the git-gate.* The git-gate scans outbound
-  refs for secrets (gitleaks), not for semantic code intent. A prompt-
-  injected agent can commit subtly malicious code — logic bombs,
-  backdoored auth paths, code that exfiltrates data through the
-  application's own HTTP clients at runtime — that looks clean to a
-  secret scanner.
-
-- *Exfiltration through allowlisted channels.* If an attacker knows or
-  can predict what hosts are in the egress allowlist, those channels are
-  available for exfiltration. A GitHub remote being allowlisted means
-  "push to an attacker-controlled fork" is viable. A logging endpoint
-  being allowlisted means structured data can leave through it. The
-  outbound DLP scanner catches credential tokens and known secrets but
-  not arbitrary business data.
-
-- *Dependency installation within the sandbox.* An agent that runs
-  `npm install` or `pip install` on attacker-specified packages executes
-  code inside the sandbox with the same capabilities the agent has:
-  filesystem access, tool calls, calls to allowlisted hosts. Supply chain
-  injection via package names is in the same injection family, triggered
-  by the same prompt-injection path.
-
-### What would close the remaining gaps
-
-The blast-radius risks above point at two distinct mitigations that
-don't yet exist in bot-bottle:
-
-- *Outbound intent classification.* The egress addon today scans
-  outbound request content for token patterns. What it lacks is
-  awareness of context — it can't distinguish "agent is pushing a
-  legitimate commit" from "agent was injected and is pushing a backdoor."
-  The `supervise` policy is already the right shape for human-in-the-loop
-  review on sensitive outbound actions; extending it with context from
-  the agent's recent tool calls (what files were touched, what was the
-  triggering task) would narrow the gap.
-
-- *Semantic code review on git push.* gitleaks is the wrong tool for
-  catching injected logic. A review step on outbound commits — even a
-  simple diff summary surfaced in `cli.py supervise` before the push is
-  forwarded — would close the malicious-commit path without requiring
-  the agent to be fully trusted.

+# Landscape: containerized AI coding agent tools
+
+Research into whether bot-bottle is redundant with existing projects, and
+whether it's worth publishing.
+
+## Summary
+
+The "AI coding agents in isolated sandboxes" space is active but not saturated.
+bot-bottle occupies a distinct position: no surveyed project combines all five
+of its defining features. Publishing is likely worthwhile, with the main risk
+being claudebox expanding to absorb the same niche.
+
+**Updated 2026-07-09:** bot-bottle now supports three isolation backends
+(Docker, Apple `container`, smolmachines/libkrun microVMs) and three built-in
+agent providers (Claude Code, OpenAI Codex, Pi) with an open plugin system for
+arbitrary providers. This meaningfully strengthens the differentiation against
+all surveyed competitors.
+
+## Closest competitor: claudebox
+
+[RchGrav/claudebox](https://github.com/RchGrav/claudebox) is the most
+feature-complete analog. It runs Claude Code in Docker with per-project
+isolated images, 15+ pre-configured dev-language profiles, and per-project
+network firewall allowlists. Actively maintained with multiple forks.
+
+What it lacks: manifest-driven named agents, per-agent env resolution modes
+(prompt / host-forward / literal), skill directory injection, per-agent system
+prompts, SSH-agent forwarding without copying private keys, home+project
+manifest merge.
+
+## Other surveyed projects
+
+- **textcortex/claude-code-sandbox → spritz** — evolved toward
+  Kubernetes-native multi-agent infra; not stdlib-first or local-Docker.
+  Original sandbox repo is archived.
+- **trailofbits/claude-code-devcontainer** — devcontainer config for security
+  audits; not a general agent launcher.
+- **Several small solo repos** (arezi/claude-sandbox, nkrefman/claude-sandbox,
+  VishalJ99/claude-docker) — lightweight Docker wrappers with no multi-agent
+  config layer.
+- **Docker's official sandbox templates** — launch-and-run Dockerfiles plus an
+  npm-based runtime; not a manifest-driven fleet manager.
+
+## Adjacent (different model)
+
+- **dagger/container-use** (mid-2025) — exposes an MCP server so the *agent*
+  spins up its own containers with Git worktrees. Inverted model vs. bot-bottle
+  (agent controls container rather than being launched into one by a manifest).
+  Still marked early-development.
+- **E2B, Northflank, Cloudflare Sandbox SDK** — cloud-hosted SaaS sandbox
+  runtimes; fundamentally different architecture.
+- **superhq.ai / SuperHQ** (v0.4.4, April 2026) — macOS desktop app (Rust/GPUI)
+  that runs Claude Code, Codex, and Pi inside microVMs via Apple's
+  Virtualization.framework (their own shuru-sdk / libkrun). Auth gateway
+  injects API keys on the wire so the sandbox never sees them; tmpfs overlay
+  stages agent writes for diff-and-accept review; mobile remote access via
+  remote.superhq.ai. Early alpha, free on launch, Apple Silicon only.
+
+  Overlap: both projects cover agent isolation, credential proxying, and
+  multi-provider support (Claude Code / Codex / Pi). Differences: SuperHQ is a
+  GUI desktop app with no manifest layer; bot-bottle is a CLI fleet manager with
+  named agents, skills injection, per-agent system prompts, and cross-platform
+  backends (Docker, Apple `container`, smolmachines). SuperHQ's microVM
+  isolation story is now partially matched by bot-bottle's `macos_container` and
+  smolmachines backends. Worth watching — it targets the same security-minded
+  power-user audience and moves fast.
+
+  **Known gap in SuperHQ (user-requested, as of 2026-07-09):** A named user
+  (Brian Cheong, Founder, Dunialabs.io) explicitly called out the absence of
+  per-run audit logging: tool calls and network egress. Bot-bottle covers both:
+  network egress is logged by pipelock/mitmproxy, and per-run op-log/audit state
+  is persisted to SQLite.
+
+- **OneCLI** ([onecli.sh](https://onecli.sh/)) — YC-backed, GA, open-source
+  (Apache-2.0, Rust) "identity gateway for AI agents": a credential/secret
+  broker that holds API keys and OAuth tokens out of the agent's reach and
+  injects them at the network layer (phantom-token — the agent sees a
+  placeholder, the gateway swaps in the real, AES-256-GCM-encrypted credential
+  at request time). Framework-agnostic and drop-in for any HTTP-calling agent,
+  50+ app integrations, plus a hosted cloud tier with a per-agent dashboard and
+  audit logs. Full technical breakdown in
+  [`agent-credential-proxy-landscape.md`](agent-credential-proxy-landscape.md).
+
+  **How close a competitor:** near-exact on the *single axis of agent secret
+  custody* — the exact thing bot-bottle sells as "the agent never sees real
+  credentials, even via `printenv`." OneCLI does that one job well, is mature
+  and funded, and is *more portable* (it sits in front of anything; bot-bottle
+  only helps agents launched through bot-bottle). Takeaway: bot-bottle should
+  stop treating secret custody as a *unique* differentiator. But OneCLI is
+  **not** a competitor to bot-bottle's actual product — it does no agent
+  sandboxing (containers/microVMs), no fleet/manifest layer, no named agents /
+  skills / per-agent system prompts, no multi-provider launching, no egress
+  firewall.
+
+  **Our edge:** (1) *Isolation is the product, not a proxy.* OneCLI keeps the
+  key out of reach at the network layer, but the agent itself still runs
+  unsandboxed — a hijacked agent behind OneCLI has full run of its host and can
+  exfil captured data through any allowed host. bot-bottle runs the agent inside
+  a kernel/VM-enforced sandbox, injects credentials across that same
+  out-of-process boundary, *and* clamps egress with pipelock — defense in depth
+  vs. a single network layer. (2) *Fleet + manifest model* with named agents,
+  skills, per-agent system prompts, multi-provider and multi-backend — OneCLI
+  has no equivalent. (3) *Trust posture:* OneCLI's managed tier reintroduces a
+  third-party credential custodian, whereas bot-bottle's OSS-runtime +
+  paid-control-plane split keeps custody inside the operator's own boundary —
+  the stronger story for the security-minded self-hoster. (4) *Runs inside your
+  network boundary — local/internal reach.* Because bot-bottle executes the
+  agent on your own host (homelab, corporate LAN, a Tailnet) and egress is a
+  manifest field, giving an agent *scoped* access to **internal** resources — a
+  private Gitea, a LAN database, a Tailscale node — is just another egress-route
+  line, not a networking project (the same move an operator already makes to
+  reach their Tailscale services). OneCLI's OSS core can self-host too, but it's
+  a credential *broker* for outbound API calls, not an agent runtime, and its
+  managed tier + 50+ integrations are oriented at public SaaS — it doesn't put
+  the agent behind your firewall for you. This is a reach advantage, distinct
+  from the isolation ones above, and it's a wedge cloud-first agent products
+  (Devin, Copilot Workspace, OneCLI Cloud) structurally can't match. **Tactical
+  read:**
+  adopt OneCLI's OSS core for the credential slice if building is undesirable
+  (it's mature now); don't build atop its managed tier (competitor, not
+  dependency); re-position bot-bottle on isolation + fleet + self-hosted custody
+  rather than "we hide your secrets."
+
+## What no found project does
+
+None combine:
+1. Named-agent manifest with per-agent env resolution (prompt / host-forward / literal), supporting multiple providers (Claude Code, Codex, Pi, arbitrary plugins)
+2. Skills directory injection
+3. Per-agent system prompts
+4. SSH-agent key forwarding without copying private keys into the container
+5. Home + project manifest merge
+6. Pluggable isolation backends: Docker (Linux/macOS), Apple `container` (macOS microVMs), smolmachines/libkrun microVMs
+7. Per-run audit log: network egress via pipelock/mitmproxy + op-log persisted to SQLite
+
+**In-flight directions (not yet shipped):**
+
+- **Forge-native dispatch (issue #317):** Gitea webhook → orchestrator spins up a bottle
+  with the issue body as prompt → agent works → bottle freezes awaiting review comment →
+  rehydrates on comment → tears down on PR close. The issue-to-PR lifecycle concept is not
+  novel (Devin, Copilot Workspace, SWE-agent all do this as cloud services); what's
+  distinct is doing it self-hosted, manifest-driven, inside bot-bottle's isolation
+  primitives.
+- **Paid web control plane (issue #327):** Browser-based multi-host agent launch and
+  monitoring; account-scoped bottle and agent definitions; secret custody (encrypted at
+  rest, injected into the sidecar at launch, never exposed to the agent or returned by any
+  read API). Monetization model: OSS runtime free, control plane paid — a standard split
+  (HashiCorp, Grafana) applied to a self-hosted agent sandbox. The principled secret
+  custody model (agent never sees real credentials, even via printenv) is more rigorous
+  than most surveyed tools but not unprecedented.
+
+## Publishing verdict
+
+Worth publishing. Differentiators that matter to the target audience (power
+users running parallel AI coding agent sessions with distinct personas/tooling):
+
+- The Python-stdlib-first, low-dependency design — competitors are npm-based,
+  Rust/GUI, or Kubernetes-native.
+- Named agents with distinct skills and system prompts, not just language profiles.
+- Multi-backend isolation: Docker, Apple `container` microVMs, and
+  smolmachines/libkrun — single manifest works across all three.
+- Multi-provider: Claude Code, Codex, Pi, plus an open plugin system for
+  arbitrary providers.
+- SSH forwarding without key copying.
+- Per-run audit log (tool calls + network egress) — an explicitly requested gap
+  in SuperHQ as of 2026-07-09.
+- Forge-native dispatch and a paid control plane (in flight) bring bot-bottle
+  into the same product category as cloud services like Devin and Copilot
+  Workspace — but self-hosted, with stronger isolation guarantees and a
+  manifest-driven fleet model those services don't have.
+
+Main risk: claudebox adds manifest/agent config; SuperHQ is moving fast on the
+GUI / microVM side. The space is moving fast enough that publishing sooner is
+better if establishing prior art matters.
+
+Discovery will be slow without active promotion; an Anthropic Discord post or
+HN "Show HN" would do most of the work.
+
+## Caveats
+
+- GitHub search cannot surface private or very new repos comprehensively.
+- Counts (stars, forks) were not confirmed for every project.
+- Initial research conducted 2026-05-07; SuperHQ entry added 2026-07-09; the space moves fast.

-# Scanning for malicious commits at the git-gate — and whether the semantic layer is a paid feature
-
-A sandboxed agent's most durable way out isn't live exfiltration — it's the
-**artifact it pushes**. Code committed through the git-gate leaves the
-sandbox and runs *later*, in CI or production, with none of the bottle's
-isolation or egress control. gitleaks covers *secrets* on that channel
-(see [`git-gate` pre-receive](../../bot_bottle/git_gate_render.py)); this
-note asks the harder question — can we scan for *malicious code* in
-commits — and the product question the answer raises: is the semantic
-(LLM) layer a decent paid feature on "git egress," alongside a paid
-human-review console for the supervise flow?
-
-## Summary
-
-- **No scanner reliably detects malicious code.** It's undecidable in
-  general and adversarial in practice — a capable agent hides a backdoor
-  from any pattern scanner (and from human reviewers). So the frame is not
-  "detect malice"; it's **raise the cost, cover the common/obvious cases,
-  and put a human on the high-leverage ones.**
-- **Layered, ranked by ROI:** (1) supply-chain / malicious-dependency
-  scanning (Socket, OSV-Scanner, GuardDog) — highest ROI, best git fit;
-  (2) fast heuristic / obfuscation / dangerous-sink scanning
-  (Semgrep-on-diff) — gitleaks-shaped; (3) **risk-based human gating** via
-  the existing supervise plane on high-risk file classes; (4) **LLM
-  semantic diff-review** as a best-effort backstop for novel backdoors.
-- **Architecture:** the git-gate's `pre-receive` is *synchronous* (it
-  blocks the push), so run only fast scanners inline and push heavy
-  analysis (CodeQL, full LLM review) to an **async post-push CI lane** that
-  can't hold the developer hostage.
-- **Monetization verdict: yes — but the paid unit is the *governed
-  git-egress review bundle*, not the raw scanner.** The pre-receive
-  mechanics and the fast OSS scanners stay free (open-core social
-  contract, same as gitleaks). The sell is the control-plane workflow
-  around them: **managed semantic review + a web-console human-review flow
-  + RBAC + audit retention + cross-run policy.** A bare per-push scan is
-  borderline "single-run = free" by our own heuristic, and its detection
-  accuracy is not something to sell on. Sell the *workflow and the
-  governance*, not the detector.
-
-## The threat: temporal escape
-
-This is the one containment fundamentally can't close. bot-bottle's VM
-isolation + egress DLP shrink *live* exfiltration, but the git push
-channel launders a payload past all of it: the agent commits code that
-looks benign at review time and does its work later, outside the
-perimeter — the "blind-XSS"-style temporal escape that both the "3 reasons
-sandboxing won't secure your AI agent" talk and Embroidery's "In sandboxes
-we (shouldn't) trust" call the sharpest gap. gitleaks gates *secrets* on
-this channel; malicious *code* is the uncovered surface, and it's the
-behavioral half of the isolation-vs-behavioral split noted in
-[`agent-sandbox-landscape.md`](agent-sandbox-landscape.md).
-
-## Why it's fundamentally hard
-
-Distinguishing malicious from legitimate code is undecidable in general
-and adversarial in the specific. The underhanded-code contests show humans
-hide backdoors from *human reviewers*; a scanner reduces to regex/dataflow
-heuristics a motivated agent writes around. So "catch malicious commits"
-is the wrong success metric. The right ones: *how much did we raise the
-cost*, *did we cover the common and the obvious*, and *did a human see the
-dangerous changes before they left*.
-
-## Landscape of git-pluggable approaches (ranked by ROI)
-
-1. **Supply-chain / malicious-dependency scanning — highest ROI.** The
-   most likely agent-introduced threat is a malicious or typosquatted
-   *dependency*, not a hand-written backdoor — and it's far more
-   detectable. **Socket** (behavioral analysis of packages: install
-   scripts, obfuscation, unexpected network/fs access, typosquats) is the
-   closest thing to malicious-intent detection that actually works;
-   **OSV-Scanner** (known-bad DB, fast) and **GuardDog** (PyPI/npm
-   heuristics) complement it. Trigger only when a commit changes a
-   lockfile/manifest → block or escalate.
-2. **Fast heuristic / obfuscation / dangerous-sink scanning.** **Semgrep**
-   with a curated ruleset, scanning the *diff* (fast enough for
-   pre-receive). Catches obfuscation (`eval(atob(...))`, base64/hex blobs,
-   minified source), exfil primitives (`curl | sh`, reverse shells,
-   DNS-exfil), and dangerous sinks (`shell=True`, `pickle.loads`, unsafe
-   `yaml.load`, `child_process.exec`). Tune noisy rules to *escalate*, not
-   block.
-3. **Risk-based human gating — the most robust control, already
-   half-built.** The git-gate already escalates `# gitleaks:allow`
-   findings to a supervisor proposal and blocks the push pending approval
-   (`supervise_gitleaks_allow`, [`git_gate_render.py`](../../bot_bottle/git_gate_render.py)).
-   Extend the same flow to **high-risk file classes**: any commit touching
-   CI/build/deploy scripts, auth/crypto code, egress config, or
-   adding/changing dependencies → route to `./cli.py supervise`. This is
-   attribution/policy, not detection, and it's the strongest thing here —
-   a human on exactly the temporal-escape surfaces.
-4. **LLM semantic diff-review — the behavioral backstop.** The only
-   approach with a shot at a novel, benign-looking backdoor: a model
-   reviews the diff for a backdoor / exfiltration / obfuscated payload /
-   dangerous behavior. This is the behavioral-detection thesis applied to
-   the *artifact* (the diff) rather than the agent's reasoning. Real
-   caveats: false positives and negatives, latency/cost, it can be
-   prompt-injected by hostile content *in the diff itself*, and it invites
-   over-trust. Useful, never a guarantee.
-
-**Not for this job:** CodeQL, Trivy, Grype, Bandit. They find *known
-vulns and insecure patterns* (bugs), not deliberate backdoors, and the
-powerful ones (CodeQL taint) need a build + database — too heavy for a
-synchronous gate. They belong in the async CI lane if at all.
-
-## Fit into bot-bottle's git-gate
-
-The `pre-receive` hook today is: gitleaks-scan each ref → escalate
-`# gitleaks:allow` findings to supervise → forward to upstream
-([`git_gate_render.py`](../../bot_bottle/git_gate_render.py)). The
-additions slot in cleanly:
-
-- **Inline (fast), before forward:** a dep-scan phase (on manifest/lockfile
-  change) and a Semgrep-diff phase. Findings block or open a supervise
-  proposal, same shape as gitleaks.
-- **New supervise tool types** alongside the existing
-  `egress-block/allow`, `gitleaks-allow`, `egress-token-allow`
-  ([`supervise_types.py`](../../bot_bottle/supervise_types.py)) — e.g. a
-  `commit-review` proposal for risky-file-class gating and for semantic
-  review. The supervise plane is already the right abstraction; this is
-  another *producer* feeding it, and [`supervise_server.py`](../../bot_bottle/supervise_server.py)
-  (JSON-RPC) is already the console backend.
-- **Async lane (heavy):** full LLM review + any CodeQL run out of band
-  after the push, feeding the same review/audit surface, so the
-  synchronous gate stays fast.
-
-## The product question: paid feature on git egress?
-
-Restating the open-core line bot-bottle runs on: *give away the
-sandbox/runtime, charge for the control plane; single-run/single-node =
-free, cross-run aggregation + central enforcement + identity/fleet = paid;
-the moat is uniform egress audit + secret custody + policy across
-untrusted agents.*
-
-Against that line, the split is clean:
-
-**Free (OSS runtime — the trust funnel):**
-- the `pre-receive` gate mechanics and gitleaks;
-- wiring the OSS scanners (Socket CLI / OSV-Scanner / Semgrep);
-- the CLI supervise flow.
-Keeping the raw scanners free is the same social contract as gitleaks and
-preserves the bottom-up distribution funnel.
-
-**Paid (the governed git-egress bundle — the control plane):**
-- **Managed semantic diff-review** — hosted inference + a curated,
-  maintained malicious-pattern/policy set. This is *capability* (metered),
-  not *insurance* — the thing individuals actually pay for. Position it as
-  **governed code-egress review**, not "we resell inference" (the
-  monetization notes explicitly warn against reselling compute).
-- **The web-console supervise/review flow — the strongest anchor.** Turn
-  the CLI `./cli.py supervise` approval into a real review surface:
-  rendered diff + finding context, approve/reject, **who-approved audit
-  trail, RBAC on approvers, mobile/phone-control** (ties to the
-  dashboard/vault north star). This is "central enforcement +
-  identity/fleet = paid" almost verbatim — and it generalizes across
-  *every* supervise proposal (egress block/allow, gitleaks-allow,
-  commit-review), so it's worth building for the whole plane, with the
-  semantic check as one producer.
-- **Cross-run governance:** fleet-wide policy for what escalates,
-  review-decision history/search/export, and drift alerts.
-
-**Why it fits the moat rather than bolting on:** a git push *is* an egress
-channel. A semantic review + human approval + audit on it extends the
-uniform "egress audit + custody + policy across untrusted agents" wedge to
-**code artifacts** — the same product, applied to the one channel gitleaks
-only half-covers. That's on-moat, not a detour.
-
-**The honest nuance (don't oversell):** a bare per-push LLM scan is
-arguably *free* by the single-run heuristic, and its detection accuracy is
-not defensible to charge for. The paid value is the **governance around
-it** — the console, RBAC, audit retention, cross-run policy — plus the
-managed capability. Sell the *review-and-approve-and-audit workflow*; let
-the detector be explicitly best-effort. And per the monetization
-guardrail, the "anti-corporate" free crowd must not veto these team
-features: the review console + RBAC + audit *are* the monetization.
-
-## Recommendation
-
-1. **Land the free layer first.** Add the dep-scan and Semgrep-diff phases
-   to `pre-receive`, and extend supervise to risky-file-class gating —
-   reuses existing machinery, immediate value, stays OSS.
-2. **Build the supervise web console** over `supervise_server`'s JSON-RPC
-   (already the Phase-1 move in the monetization path). This is the paid
-   anchor and it serves *all* proposal types, not just commit review.
-3. **Add managed semantic diff-review as a paid producer** feeding that
-   console — "governed code-egress review," metered, explicitly
-   best-effort on detection.
-4. **Don't oversell detection.** Market the workflow (review + approve +
-   audit) and the cross-run policy/RBAC, where the value is real and
-   defensible; keep the raw scanners open.
