fix(git-gate): scan $new --not --all for every push, not $old..$new

The pre-receive hook scanned existing-branch updates with the delta range
$old..$new. On a rebase / non-fast-forward force-push onto an advanced main,
$old is no longer an ancestor of $new, so $old..$new expands to all of main's
new history — including the deliberate sandbox-escape gitleaks fixtures — and
the push is rejected on commits that belong to main, not the branch.

Unify the range on `$new --not --all` for every non-delete push (this is the
deferred open question from PRD 0028, which already applied it to new refs
for #106). It scans only the commits the push introduces and is
security-equivalent: the bare repo's refs come only from trusted upstream
mirror-fetch and gitleaks-gated pushes, so an excluded commit is
already-upstream or already-scanned. It is also more correct for
non-fast-forward pushes, where $old..$new can skip commits off the direct path.

Fixes #421

+# 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: Claude forward_host_credentials
-
-- **Status:** Draft
-- **Author:** claude
-- **Created:** 2026-07-01
-- **Issue:** #325
-
-## Summary
-
-Add `agent_provider.forward_host_credentials: true` support for the
-`claude` template, mirroring the existing Codex flow. When enabled,
-bot-bottle reads the host's Claude OAuth session key from
-`~/.claude/.credentials.json` at launch, forwards it only to the egress sidecar,
-and injects a placeholder `CLAUDE_CODE_OAUTH_TOKEN` into the agent so
-Claude Code starts without ever seeing the real credential.
-
-## Problem
-
-Running a Claude agent in a container today requires the operator to
-manually extract a long-lived OAuth token (`claude setup-token`), export
-it as `BOT_BOTTLE_CLAUDE_OAUTH_TOKEN`, and reference it explicitly in
-the manifest with `agent_provider.auth_token:
-"BOT_BOTTLE_CLAUDE_OAUTH_TOKEN"`. This is a two-step manual ceremony
-that is easy to skip or do incorrectly.
-
-The host already stores a valid Claude session in `~/.claude/.credentials.json`
-after `claude login`. Codex already automates an
-equivalent extraction from `~/.codex/auth.json`. There is no reason
-Claude bottles cannot do the same.
-
-## Goals / Success Criteria
-
-- A Claude bottle with `forward_host_credentials: true` in the manifest
-  uses the host's `~/.claude/.credentials.json` session key at launch with no
-  additional operator steps.
-- The agent container receives only `CLAUDE_CODE_OAUTH_TOKEN=egress-placeholder`
-  — never the real token.
-- The real session key lives only in the egress sidecar's environment.
-- Missing, malformed, or expired host Claude auth fails launch with a
-  clear operator-facing message.
-- Existing `auth_token` behavior is unchanged.
-- `forward_host_credentials: true` is rejected in the manifest when both
-  `auth_token` and `forward_host_credentials` are set, since they serve
-  the same purpose.
-
-## Non-goals
-
-- Refreshing Claude OAuth tokens in the sidecar.
-- Writing a dummy `~/.claude.json` auth state to the agent (unlike the
-  Codex flow, Claude Code reads its credential from `CLAUDE_CODE_OAUTH_TOKEN`
-  in env, not from an auth file — no guest-side auth marker is needed).
-- Supporting `forward_host_credentials` for providers other than `codex`
-  and `claude`.
-
-## Design
-
-### Manifest schema
-
-```yaml
-agent_provider:
-  template: claude
-  forward_host_credentials: true
-```
-
-Rejects in manifest validation when:
-- Template is not `codex` or `claude`.
-- Both `auth_token` and `forward_host_credentials` are set.
-
-### Host auth extraction (`contrib/claude/claude_auth.py`)
-
-Claude Code credential storage varies by platform:
-
-- **Linux**: `~/.claude/.credentials.json`
-- **macOS**: macOS Keychain, service `"Claude Code-credentials"`
-  (the file path is tried first; Keychain is the fallback when the file
-  is absent)
-
-`~/.claude.json` contains only UI state and profile metadata — no token.
-
-The credentials JSON schema (same whether from file or Keychain):
-
-```json
-{
-  "claudeAiOauth": {
-    "accessToken": "<access-token>",
-    "refreshToken": "<refresh-token>",
-    "expiresAt": 1748276587173,
-    "scopes": ["user:inference", "user:profile"]
-  }
-}
-```
-
-`expiresAt` is in **milliseconds** (not seconds).
-
-At prepare/launch time, when `forward_host_credentials: true`:
-
-1. Try `~/.claude/.credentials.json`; on macOS, if absent, run
-   `security find-generic-password -s "Claude Code-credentials" -w`
-   and parse its stdout as JSON.
-2. Require a `claudeAiOauth` dict.
-3. Require a non-empty `claudeAiOauth.accessToken` string.
-4. If `claudeAiOauth.expiresAt` is present, divide by 1000 and require
-   the result to be in the future.

-When `forward_host_credentials: true`:
-
-- Provision the session key in `provisioned_env` under
-  `BOT_BOTTLE_CLAUDE_HOST_ACCESS_TOKEN` (new constant in `egress.py`).
-- Set up the `api.anthropic.com` egress route with `auth_scheme: Bearer`
-  and `token_ref: BOT_BOTTLE_CLAUDE_HOST_ACCESS_TOKEN`.
-- Set `CLAUDE_CODE_OAUTH_TOKEN=egress-placeholder` in the agent env and
-  add it to `hidden_env_names`.
-
-No dummy auth file and no `verify` step are needed — Claude Code reads
-the credential from the env var, not from a file.
-
-### Constants
-
-- `CLAUDE_HOST_CREDENTIAL_TOKEN_REF = "BOT_BOTTLE_CLAUDE_HOST_ACCESS_TOKEN"`

   (`sandbox-exec`, Podman + Landlock).

+- **Source**: https://github.com/TencentCloud/CubeSandbox ;
+  HN launch https://news.ycombinator.com/item?id=47863430
+- **License**: Apache 2.0 (~10.4k stars). By Tencent Cloud; described as
+  "battle-tested, production-ready" infra already running in Tencent
+  Cloud. Rust / Go / C.
+- **Isolation**: MicroVMs via RustVMM + KVM — "each sandbox gets its own
+  Guest OS kernel, no Docker shared-kernel escapes." Hardware-level
+  isolation, dedicated kernel per instance.
+- **Locality**: Self-hosted, but **server/cluster-oriented**, not a
+  single-user local CLI. Deploy guides target PVM cloud VMs, bare metal,
+  and dev. A single 96-vCPU host is claimed to run 2,000+ concurrent
+  sandboxes.
+- **Agent integration**: **Drop-in E2B SDK replacement** (single env-var
+  change) — the headline compatibility claim. OpenClaw assistant
+  integration; general LLM-code execution. Aimed at platform builders,
+  not one developer's laptop.
+- **Config**: Programmatic via the E2B-compatible SDK. No declarative
+  manifest.
+- **Network policy**: This is the striking part — **domain allowlists,
+  instant block on unauthorized egress, full audit logs, per-sandbox
+  traffic tokens, policy-routing egress**, enforced by an eBPF-based
+  virtual switch giving kernel-level network isolation. Closest match yet
+  to bot-bottle's own default-deny + per-bottle allowlist egress model.
+- **Credentials**: **Credential vault** — agents call external APIs / LLMs
+  while "keys never enter the sandbox, model context, or logs." Same
+  in-flight-injection idea as matchlock, but productized as a vault.
+- **Performance**: <60ms cold start (claimed 2.5–50× faster than
+  alternatives), <5MB memory per instance; millisecond snapshot rollback
+  is upcoming.
+- **Maturity**: Open-sourced July 2026 off production Tencent Cloud use;
+  most-starred project in this set (~10.4k).
+
+### Cleanroom *(added 2026-07-18)*
+- **Source**: https://github.com/buildkite/cleanroom
+- **License**: Apache 2.0
+- **Isolation**: MicroVM — Firecracker on Linux, Virtualization.framework
+  on macOS. Digest-pinned OCI images.
+- **Locality**: Self-hosted server (CI-oriented).
+- **Agent integration**: Generic process sandbox; CI-first, not a
+  Claude/agent wrapper.
+- **Config**: `cleanroom.yaml` in the repo being sandboxed defines egress
+  rules, resources, and network policy. Cleanroom resolves this from the
+  commit being run.
+- **Network policy**: Default-deny + per-repo hostname allowlist (resolved
+  from DNS answers + destination IP:port). Co-hosted services on the same
+  IP:port are not distinguished. OIDC-backed auth for remote servers.
+- **Credentials**: Host-side only; not injected in-flight but not present
+  in the VM.
+- **Notable**: Policy lives in the *repo being sandboxed*, not in an
+  agent-role definition — closer to per-repo scoping than per-role.
+  Supports Docker-inside-sandbox (`services.docker.required: true`), OIDC
+  authorization, suspend/resume lifecycle.
+- **Maturity**: Active Buildkite product.

+- **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.
+
+## 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.
+- **Maturity**: Specification + reference implementation, 2026.

 ## 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.
+
+**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.

+  2,000+ sandboxes per 96-vCPU host) are the project's own launch claims,
+  not independently verified here.
+
+## Addendum 2026-07-18 — CubeSandbox and the positioning read
+
+CubeSandbox (Tencent Cloud, Apache 2.0, ~10.4k stars, HN launch
+[#47863430](https://news.ycombinator.com/item?id=47863430)) is the first
+project in this survey to combine, in one open-source stack, everything
+bot-bottle treated as its differentiator:
+
+- **Egress custody (connection level)** — default-deny domain allowlist
+  (L7 domain/SNI filtering), instant block on unauthorized egress,
+  per-sandbox traffic tokens, full audit logs of destinations (eBPF
+  virtual switch, "CubeVS"). This matches bot-bottle's egress scanner at
+  the *connection level*, productized — see the one thing it does **not**
+  match, below.
+- **Credential custody** — a vault where keys "never enter the sandbox,
+  model context, or logs." This is the in-flight-injection idea from
+  matchlock, but as a first-class feature, and it's exactly the
+  cross-vendor "egress audit + custody" wedge the monetization
+  positioning treats as the one defensible moat.
+- **Isolation on par with bot-bottle's current default** — a dedicated
+  guest kernel per sandbox (RustVMM/KVM). bot-bottle now defaults to the
+  same class of boundary (Firecracker microVM / Apple Container), so this
+  is parity, not an edge; CubeSandbox's remaining edge is running that
+  per-kernel isolation multi-tenant at scale on one host.
+
+The one axis CubeSandbox does **not** cover — and where bot-bottle stays
+distinctive:
+
+- **Content DLP on *authorized* channels.** CubeSandbox's egress control
+  is connection-level: it decides *whether* a destination is allowed and
+  logs it, and its vault keeps *injected* credentials out of the sandbox
+  entirely. Neither inspects the *payload* of traffic to an allowed
+  destination. So an agent that exfiltrates over a permitted channel —
+  pasting a repo's contents, an agent-derived secret, or PHI into an
+  allowed API/domain — is not caught by CubeSandbox. bot-bottle's own
+  egress DLP scanner does scan that: response + websocket content against
+  the resolved per-flow config, with per-bottle token redaction (see
+  recent egress commits). The vault
+  approach is arguably *stronger* for the specific case of pre-known
+  injected credentials (they can't leak if they were never present), but
+  it is not a substitute for content inspection of everything else.
+
+**Long-running posture — a sharper axis than raw isolation.** E2B and
+CubeSandbox are *ephemeral-per-task* by design; a long-running agent is an
+architected pattern on top, not the default. E2B: 5-minute default
+timeout, continuous runtime tier-capped (~1h Hobby / ~24h Pro), duration
+achieved via **pause/resume** (preserves filesystem + memory + processes;
+reconnect by sandbox ID via `Sandbox.connect()`; resume resets the timeout
+to 5 min; auto-pause via `on_timeout: "pause"`). CubeSandbox mirrors this
+(E2B drop-in) with first-class auto pause/resume and hundred-ms
+checkpoint/fork — and, self-hosted, sets its own timeout policy with no
+vendor tier caps. bot-bottle inverts the model: a bottle is **persistent,
+named, and supervised by default** — long-running *is* the default, not a
+session-management loop over pause/resume. smolmachines is the other
+persistent-by-default project in this set. For anyone building agents that
+run for hours/days, this posture difference matters more than the
+isolation primitive.
+
+**DX — the "run Claude yolo-style" bar.** The reason `claude
+--dangerously-skip-permissions` is so widely used is DX: it's one command
+and the agent just goes. The bottle thesis is to make a *sandboxed* run
+that easy — `start <agent>` builds the image on first run and drops you
+into an interactive Claude session that already has
+`--dangerously-skip-permissions` on by default
+(`contrib/claude/agent_provider.py`), with the sandbox as the guardrail
+instead of per-action prompts. On this axis the field splits cleanly:
+- **Wrappers around the agent** (as-easy-as-native): bot-bottle and
+  **agent-safehouse** (`safehouse claude --dangerously-skip-permissions`).
+  These *are* the run-Claude experience. agent-safehouse is the real DX
+  peer — but it's macOS-only Seatbelt, single-run, and doesn't address
+  network egress; bot-bottle adds VM-grade isolation, egress DLP, and
+  persistent/parallel bottles across macOS + Linux.
+- **Libraries / services** (you build the run yourself): boxlite,
+  microsandbox, CubeSandbox, E2B. 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, and the only project that
+matches it (agent-safehouse) does so with materially weaker isolation and
+no egress story. "As easy as native yolo, but actually sandboxed" is a
+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
+   JSON 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** — a well-funded, 10k-star open-source project now ships it.
+  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) before the next iteration of bot-bottle's
+  in-flight-secret feature — see borrowable idea #2 above.
+
+## 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.
+
+**Borrowable from new tools:**
+
+- **Microsoft AGT's trust-score decay** — privilege that reflects
+  observed behaviour rather than static provisioning. Applied to
+  bot-bottle: a bottle that has triggered DLP alerts or supervise holds
+  could auto-downgrade its network preset, or flag the session for
+  closer review. Fits the existing supervise-server architecture.
+- **Docker sbx's live network TUI** — real-time per-session view of
+  allowed and blocked outbound connections with point-and-click
+  allow/block. `cli.py supervise` is the right surface; adding a
+  live-connections panel would directly address the "I can't see what
+  the agent is doing" gap without any backend changes.
+- **OAP's cryptographic audit chain** — Ed25519-signed, hash-chained
+  audit records. Currently bot-bottle logs egress decisions but doesn't
+  chain them. A tamper-evident audit record per session would be useful
+  for the compliance use case the CubeSandbox positioning targets.

+# HN discourse on agent sandbox safety — June/July 2026
+
+A survey of community opinion and notable security disclosures on Hacker
+News and adjacent sources over June–July 2026. The question: what does
+the current discourse say about whether sandboxes are sufficient for
+agentic AI safety, and where does bot-bottle land against the issues
+being raised?
+
+Research conducted 2026-07-18.
+
+## Summary
+
+The past month marks a turning point in community opinion. Earlier in
+2026, the debate was mostly "which sandbox tool is best?" By June–July,
+a cascade of critical CVEs and novel attack classes has shifted the
+framing to "sandboxes are not enough — what else do you need?" The
+attacks that drove this shift are structurally distinct: most route
+through legitimate, trusted channels (Sentry issues, MCP descriptions,
+README files) rather than exploiting the isolation boundary directly.
+
+bot-bottle's architecture holds up well against the direct-escape class
+(Firecracker/Apple Container default backends, credentials never in the
+agent's env, harness entirely on the host). The remaining gap is prompt
+injection — attacker-controlled data interpreted as model instructions.
+Egress controls and prompt injection defenses are orthogonal: egress
+limits what the agent can *send out*; injection is about what it is
+*told to do*. The two don't substitute for each other. Inside a tightly-
+egressed sandbox a successful injection can't exfiltrate to unknown
+hosts, but it can still corrupt the work product, push malicious commits
+past a secret scanner, or use allowlisted channels for exfiltration.
+Those residual risks are addressed below.
+
+## The sandboxing boom sets the stage
+
+The preceding months generated a wave of sandbox tooling. A March 28
+Ask HN thread
+([#47444917](https://news.ycombinator.com/item?id=47444917)) catalogued
+the explosion: E2B, AIO Sandbox, AgentSphere, Yolobox, Exe.dev,
+AgentFence, DenoSandbox, Capsule (WASM), ERA, Vibekit, Daytona, Modal,
+Nono, and more — all launched within roughly 12 months. A parallel March
+9 thread ([#47185250](https://news.ycombinator.com/item?id=47185250))
+surveyed what developers were actually deploying: "containers or YOLO"
+dominated. The honest community mood was that most teams hadn't solved
+this and were shipping anyway.
+
+## The 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

+# 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.
