fix(login): narrow exception types and cover cleanup path

Replaces broad `except Exception` with specific types that reflect the actual failure modes: - _save_credentials: `except OSError` (IO-only path; re-raises for cleanup) - _post error handler: `except (OSError, ValueError)` (network + bad JSON) - poll-loop: `except (OSError, ValueError)` (network + bad JSON) Also: - Simplify _fake_get to use next(..., default) — removes uncovered StopIteration branch - Add encoding="utf-8" to open() in test_approved_flow_returns_0 - Add test_cleanup_on_write_failure to cover the except OSError block in _save_credentials All files score 10.00/10 on pylint (fail-under=10) and 0 errors on pyright strict.

+"""Consolidated bottle launch sequence for the macOS backend (PRD 0070).
+
+The docker backend allocates a free address, pins the agent to it with
+`--ip`, registers it, *then* starts the agent — registration precedes launch
+because the pinned address is known up front.
+
+**Apple Container 1.0.0 has no `--ip`.** The `--network` flag takes only
+`<name>[,mac=…][,mtu=…]`; the address is assigned by vmnet's DHCP and is
+knowable only once the container is running. So the macOS order inverts:
+
+    ensure_gateway()  ->  caller starts the agent  ->  register_agent(source_ip)
+
+That is why this module exposes two functions where docker has one — the
+caller has to start the agent in between. `ensure_gateway` runs first because
+the agent's proxy env needs the gateway's address at `container run` time; the
+agent's *own* address (the attribution key) only exists afterwards.
+
+The control plane and the gateway are one **infra container** here (see
+`infra`), so `gateway_ip` and the control-plane host are the same address.
+
+The consequence for the identity token: it is minted by registration, i.e.
+*after* the agent container exists, so it cannot be baked into the run-time
+env the way docker's compose spec does. It is delivered at `container exec`
+time instead — see `bottle.MacosContainerBottle`.
+
+That delivery is load-bearing, not a nicety: `/resolve` requires a matching
+`(source_ip, identity_token)` pair and fail-closes with no source-IP-only
+fallback (#366). So egress that does not carry the token is denied — which is
+the safe direction, and is why the agent's init process is a bare `sleep` and
+every real command arrives through `container exec`.

+"""The per-host infra container for the macOS backend (PRD 0070).
+
+A single persistent Apple container that runs BOTH the orchestrator control
+plane and the gateway data plane — the macOS analogue of the Firecracker infra
+VM (`backend/firecracker/infra_vm.py`), not the docker backend's two separate
+containers.
+
+Why one container, not two: Apple Containers are lightweight VMs, each with its
+own kernel. The docker backend runs the orchestrator and gateway as two
+containers safely because they share the host kernel, so their concurrent
+writes to the one `bot-bottle.db` (the orchestrator's registry + the gateway
+supervise daemon's queue) are serialized by coherent `fcntl` locks. Across two
+*guest* kernels sharing a virtiofs-mounted DB those locks are not coherent, and
+concurrent writers can corrupt the file. Firecracker solved this by putting
+both services in one guest with the DB on a device only that guest mounts; this
+does the same with Apple primitives.
+
+Two consequences fall out of the single container, both simplifications:
+
+- **No DNS dance.** The control plane and the gateway daemons reach each other
+  over `127.0.0.1`, so nothing depends on Apple's (absent) container DNS and
+  there is no orchestrator-before-gateway ordering to get right.
+- **The DB is never host-shared.** It lives on a container-only volume, so no
+  host process opens the live file. The host CLI reaches registry + supervise
+  state through the control-plane HTTP surface (`cli/supervise.py` already uses
+  `OrchestratorClient`), exactly as it does for firecracker.
+
+The control-plane source is bind-mounted (like the docker orchestrator), so a
+code change takes effect on the next launch without an image rebuild; the
+gateway daemons are baked in the gateway image and rebuild through its own
+digest check.

-This backend launched a per-bottle companion container (the egress /
-git-gate / supervise data plane) alongside the agent container, with the
-agent's proxy env pointed at the companion's host-only IP. That
-per-bottle-companion architecture was removed in the companion-container removal;
-the macOS backend will be re-enabled once it grows the consolidated
-per-host gateway the docker backend already uses.
+The agent container attaches to the **shared host-only gateway network** and
+proxies egress through the one per-host gateway, replacing the per-bottle
+companion container removed in #385.

-Until then, launching a macOS bottle fails closed. `prepare` / `status`
-/ cleanup still work.
+The order differs from docker's, forced by Apple Container 1.0.0 having no
+`--ip` (see `consolidated_launch`): the agent is started *before* it is
+registered, because its DHCP-assigned address — the attribution key — does not
+exist until then.
+
+    gateway up -> run agent -> read its IP -> register it -> provision
+
+Two things follow from that inversion:
+
+- The **identity token** is minted by registration and so cannot be in the
+  agent's run-time env; it rides the proxy URL applied at `container exec`
+  time (`bottle.MacosContainerBottle`). `/resolve` requires it (#366), so
+  egress without it is denied — hence the bare `sleep` init: every real agent
+  command goes through exec and therefore carries the token.
+- The agent is run with `--cap-drop CAP_NET_RAW`. Apple Container grants
+  NET_RAW by default, which would let an agent open a raw socket and forge a
+  neighbour's source address on the shared segment. NET_ADMIN is already
+  absent (the agent cannot change its own address or route), so dropping
+  NET_RAW is what closes the source-address half of PRD 0070's invariant:
+  "a packet's source address, as seen by the orchestrator, provably identifies
+  the originating bottle." The identity token is the other half — an attacker
+  would need to forge the address *and* steal the token — but the invariant is
+  a stated precondition of consolidation, so it is enforced on its own terms
+  rather than left to the token.

+        sweep in `register`. Neither runs when the launching CLI dies hard —
+        SIGKILL, a closed terminal, a host sleep/crash — so the row outlives

+            rule `register`'s same-IP supersede sweep applies. Without this
+            second case a recycled address stays ambiguous, which is exactly
+            the state that resolves no policy.
+
+        `grace_seconds` protects an in-flight launch: registration happens
+        moments after `container run`, and a concurrent launch's address may
+        not be visible to the caller's enumeration yet. Rows younger than the

 Speaks MCP over HTTP+JSON-RPC. Methods handled:

  * `initialize`           — handshake; returns server info + caps.
  * `notifications/initialized` — ack-only.
  * `tools/list`           — returns the tool definitions.
-  * `tools/call`           — validates, queues, blocks, returns.
+  * `tools/call`           — validates, queues, waits out the grace
+                             window, returns (pending past it); or, for
+                             `check-proposal`, a non-blocking status poll.

 Everything else returns JSON-RPC error -32601 (method not found).

-Stdlib-only. The Dockerfile copies this file + bot_bottle/supervise.py
-into the image; the server imports `supervise` for the queue / Proposal
-plumbing.
+The Dockerfile copies this script to /app/supervise_server.py and installs
+the bot_bottle package so its `from bot_bottle.*` imports resolve.

+# ADR 0005: Keep tracker metadata on issues
+
+- **Status:** Accepted
+- **Date:** 2026-07-18
+- **Deciders:** didericis
+
+## Context
+
+Gitea exposes labels on both issues and pull requests. Applying the same labels
+to both copies planning metadata, creates a synchronization obligation, and
+makes disagreements between the two records possible. At the same time,
+unlabelled objects look accidental unless the repository states which object
+owns the metadata.
+
+The repository already uses issues as work items and PRs as implementations of
+those work items. At this decision's cutoff, all open PRs reference issues, but
+121 of 219 historically merged PRs do not. Manufacturing retrospective issues
+for that history would create records that never participated in planning and
+would make the issue history less truthful.
+
+## Decision
+
+Issues are the canonical tracker records and own labels. Every issue has at
+least one label. An issue opened or left without labels receives
+`Status/Needs Triage` automatically until it is classified.
+
+Pull requests carry no labels. Every new PR deliberately references at least
+one existing issue in its title or description with one of these forms:
+
+- `Closes #123`, `Fixes #123`, or `Resolves #123` when merging completes it.
+- `Part of #123`, `Related to #123`, `Refs #123`, or `References #123` when it
+  contributes without completing it.
+
+Gitea Actions enforces both PR rules as a status check and repairs the empty
+issue-label state. Branch protection makes the PR policy check required.
+
+The policy applies from 2026-07-18 onward. Existing issues may be labelled as
+they are encountered, but closed PRs are grandfathered: no retrospective
+issues or PR labels are created solely to make history conform.
+
+## Consequences
+
+- Classification, priority, and workflow metadata have one source of truth.
+- A PR's issue link is the navigation path to its planning metadata.
+- Multi-PR issues do not require copied or synchronized labels.
+- `Status/Needs Triage` is an intentional fallback, not a final
+  classification.
+- Direct issue creation remains convenient; automation repairs a missing label
+  immediately after creation because Gitea has no native required-label rule.
+- The required check must be configured in branch protection after this
+  workflow lands.

+# 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.)

 ## Summary

-Eight projects surveyed. None duplicate bot-bottle's combination of
-local Docker, declarative JSON manifest, per-agent egress allowlist via
-pipelock, and bottle/agent split. Two clusters stand out:

+egress allowlist + outbound-content DLP, bottle/agent split, and the
+composable `extends:` policy model. Three clusters stand out:

 - **Closest neighbours** — agent-safehouse and litterbox: local,
  single-user, thin wrappers over an existing OS primitive
  (`sandbox-exec`, Podman + Landlock).
- **Different category** — tilde.run (hosted SaaS), boxlite and

  (capability-security paradigm, no OS isolation).
+- **New: governance/pre-action layers** — Microsoft AGT and Open Agent

+  policy, but operate at the tool-call level rather than providing
+  network/filesystem isolation; they complement rather than substitute.

+
+- **Source**: https://github.com/e2b-dev/e2b ; https://e2b.dev/docs
+- **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.
+- **Config**: Programmatic SDK/API plus templates. Network configuration
+  supports internet on/off, outbound allow/deny rules, and a custom egress
+  proxy.
+- **Network policy**: Configurable per sandbox, but not documented as
+  default-deny and no built-in outbound-content DLP is documented.
+- **Credentials**: Environment variables passed to the sandbox are explicitly
+  not private at the OS level. No built-in in-flight application-credential
+  injection is documented.
+- **Persistence**: Full memory + filesystem pause/resume, snapshots, and
+  auto-resume. Continuous runtime is tier-limited, while paused sandboxes are
+  retained indefinitely.
+- **Maturity**: Established hosted platform and the API compatibility target
+  used by CubeSandbox.
+
+### 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;

+  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
+Claude-specific note, so they remain outside the main comparison table rather

+- **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.
+
+## Claude-specific wrappers and developer environments
+
+These projects were the focus of the original containerized-Claude survey.
+They remain useful comparisons for local developer experience, but most are
+templates or wrappers rather than policy-bearing sandbox platforms, so they
+are grouped here instead of widening the main table further.
+
+### claudebox
+
+- **Source**: https://github.com/RchGrav/claudebox
+- **Isolation**: Docker, with per-project images, authentication state, and
+  configuration.
+- **Agent integration**: Claude Code wrapper with 15+ preconfigured language
+  and task profiles.
+- **Network policy**: Per-project firewall allowlists.
+- **Closest overlap**: local one-command developer workflow and project-scoped
+  network policy.
+- **Difference**: profiles describe development toolchains, not named agent
+  roles. There is no bottle/agent split, composable role manifest, provider
+  plugin layer, or outbound-content DLP.
+
+### Spritz / claude-code-sandbox
+
+- **Source**: https://github.com/textcortex/claude-code-sandbox (archived;
+  points to its successor, Spritz).
+- **Isolation**: The original project ran Claude Code in local Docker with
+  bypass permissions; Spritz moved toward Kubernetes-native multi-agent
+  infrastructure.
+- **Difference**: the successor targets cluster orchestration rather than a
+  low-dependency local launcher. It is architecturally closer to hosted or
+  Kubernetes platform runtimes than to bot-bottle's single-operator CLI.
+
+### 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.
+
+### Microsoft Agent Governance Toolkit (AGT) *(added 2026-07-18)*
+- **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.
+- **Maturity**: MIT, ~3.3k ⭐, v3.7.0 May 2026.
+
+### Open Agent Passport (OAP) *(added 2026-07-18)*
+- **Source**: https://github.com/aporthq/aport-spec ; spec at
+  https://api.aport.io/spec/spec/oap/oap-spec.md/ ; arXiv 2603.20953
+- **License**: Open specification.
+- **Isolation**: None. Pre-action hook only — intercepts tool calls
+  synchronously before execution, evaluates against a cloud-registry
+  declarative policy, fails closed.
+- **Locality**: Local hook + cloud policy registry.
+- **Agent integration**: Framework-agnostic; hook pattern.
+- **Config**: Declarative policy rules in a cloud registry (evaluated in
+  order; first failing rule denies). Ed25519-signed, hash-chained audit
+  records per decision.
+- **Network policy**: Not directly.
+- **Notable**: 53ms median authorization decision (N=1,000). In an
+  adversarial testbed ($5,000 bounty, 1,151 sessions), social engineering
+  succeeded 74.6% of the time under a permissive policy; under a
+  restrictive OAP policy, 0% success across 879 attempts. Assumes
+  framework runtime is not compromised.

 ## 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 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.
+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.

 **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. boxlite and
-microsandbox are infrastructure libraries 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

-What bot-bottle already has that the survey suggested as
-differentiators:
- Default-deny egress with a per-agent allowlist (pipelock).
+### Already shipped or otherwise addressed
+
+- Default-deny egress with a per-agent allowlist (own egress scanner).
 - 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.

-Ideas worth considering, without abandoning the Python-stdlib-first / local-Docker
-stance:
+### Still worth considering

-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.
+- **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.

 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.

+  (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.

+
+## Addendum: consolidated-gateway findings (2026-07-17, PRD 0070)
+
+Re-tested on Apple Container 1.0.0 while porting the backend to the
+per-host consolidated gateway (#351). The two-network shape above still
+holds; these are the additional constraints that shaped the port, each
+verified against the live CLI on this host.
+
+### No static IP for a container
+
+`container run --network` accepts only
+`<name>[,mac=XX:XX:XX:XX:XX:XX][,mtu=VALUE]`. There is no `--ip`. The
+address comes from vmnet's DHCP and is knowable only after the container
+is running:
+
+```console
+$ container run --name a --network bb-net --detach alpine sleep 900
+$ container inspect a | jq -r '.[0].status.networks[0].ipv4Address'
+192.168.128.3/24
+```
+
+Consequence: the docker backend's "allocate a free IP -> pin it with
+`--ip` -> register -> launch" order cannot be reproduced. macOS inverts
+it to "launch -> read the assigned address -> register". The identity
+token therefore cannot be in the agent's run-time env (registration mints
+it after the container exists) and is delivered at `container exec` time.
+
+### Networks are fixed at run time
+
+There is no `container network connect`; `container network` exposes only
+`create`, `delete`, `list`, `inspect`, `prune`. A network cannot be
+attached to a running container, so a *persistent* shared gateway rules
+out per-bottle networks — they would force a gateway restart per launch.
+One shared host-only network, created up front, is the only shape that
+keeps the gateway a singleton.
+
+### No container DNS
+
+Containers cannot resolve each other by name; the host-only network's
+resolver refuses the query:
+
+```console
+$ container exec agent nslookup gw
+;; connection timed out; no servers could be reached
+$ container exec agent cat /etc/resolv.conf
+nameserver 192.168.128.1
+```
+
+Consequence: the gateway is handed the control plane's **IP**, not a
+container name as on docker. That forces the startup order
+orchestrator -> read its address -> gateway.
+
+### The host can reach the host-only network directly
+
+```console
+$ container inspect c | jq -r '.[0].status.networks[0].ipv4Address'
+192.168.128.2/24
+$ curl -s http://192.168.128.2:8099/i
+ok
+```
+
+So no `--publish` hop is needed: the host CLI and the gateway use the
+same control-plane URL. Docker needs `--publish 127.0.0.1:...` plus a
+separate internal URL for the same job.
+
+### CAP_NET_RAW is granted by default — and matters for attribution
+
+Apple grants NET_RAW but not NET_ADMIN. The agent therefore cannot change
+its own address or route:
+
+```console
+$ container exec agent ip addr add 192.168.128.99/24 dev eth0
+ip: RTNETLINK answers: Operation not permitted
+$ container exec agent ip route replace default via 192.168.128.2 dev eth0
+ip: RTNETLINK answers: Operation not permitted
+$ container exec agent grep CapEff /proc/self/status
+CapEff:	00000000a80425fb        # bit 13 (NET_RAW) set, bit 12 (NET_ADMIN) clear
+```
+
+But NET_RAW permits raw sockets, i.e. source-address forgery against
+neighbours on the shared segment — directly against PRD 0070's invariant
+("a packet's source address, as seen by the orchestrator, provably
+identifies the originating bottle"). `--cap-drop CAP_NET_RAW` closes it:
+
+```console
+$ container run --cap-drop CAP_NET_RAW ... alpine
+$ container exec nr grep CapEff /proc/self/status
+CapEff:	00000000a80405fb        # bit 13 cleared
+$ container exec nr ping -c1 192.168.128.2
+ping: permission denied (are you root?)
+```
+
+The agent is run with `--cap-drop CAP_NET_RAW` for this reason.
+
+### `container exec` inherits run-time env, and `--env` overrides it
+
+```console
+$ container run --name e --env FOO=from_run --detach alpine sleep 120
+$ container exec e sh -c 'echo $FOO'
+from_run
+$ container exec --env FOO=from_exec e sh -c 'echo $FOO'
+from_exec
+```
+
+This is what makes exec-time identity-token delivery work: the token-less
+proxy URL baked in at launch is superseded by the token-bearing one at
+exec. Bare `--env NAME` (inherit from the parent process) keeps the token
+value off argv.

+# 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.
