ci(prd): rename PRD to prd-new placeholder per new convention

Token patterns: HuggingFace (hf_), Databricks (dapi), Slack (xox[baprs]-),
npm (npm_), SendGrid (SG.x.y), PyPI (pypi-), HashiCorp Vault (hvs.).

Unicode normalization (_normalize_text) applies NFKD + strips combining
marks and control chars before pattern matching, defeating fullwidth-char
and combining-mark evasion.

CRLF injection (scan_crlf_injection) detects %0d%0a in URLs and literal
\r\n header-injection patterns; runs unconditionally in scan_outbound
regardless of outbound_detectors config.

 ## Features
 
-- **Per-bottle egress allowlist** — TLS-bumped HTTP/HTTPS chokepoint with a per-manifest host allowlist; per-route path/method/header `matches` filtering; outbound DLP scanning for known tokens and secrets, inbound DLP scanning for prompt-injection attempts; DoH and arbitrary hosts blocked by default.
+- **Per-bottle egress allowlist** — TLS-bumped HTTP/HTTPS chokepoint with a per-manifest host allowlist and request-body DLP scanner; DoH and arbitrary hosts blocked by default.
 - **Tokens the agent never sees** — host secrets live in a sidecar; the agent dials `http://sidecar:9099/<path>` and the proxy strips inbound `Authorization` and injects the real token before forwarding. `printenv` in the agent shows proxy URLs only.
 - **Gitleaks-scanned push (git-gate)** — `bottle.git` remotes route through a per-bottle `git daemon` that gitleaks-scans incoming refs pre-receive and forwards clean refs upstream over SSH. The agent never holds the upstream credential.
 - **Manifest-scoped skills + secrets** — each bottle declares its skills, env, git identity, remotes, and egress routes; unknown keys die at load.
 - **Trust boundary at `$HOME`** — bottles (credentials, egress, remotes) live only under `~/.bot-bottle/bottles/`. Repos may ship agents but not bottles, so a cloned repo can't redirect an env var to an attacker host.
 - **Composable bottles (`extends:`)** — keep provider/runtime policy in one base bottle (e.g. `claude.md`) and overlay task bottles on top.
-- **Parallel, isolated bottles** — each bottle runs in its own backend-owned isolation boundary; bottles don't share state or talk to each other.
+- **Parallel, isolated bottles** — each bottle is its own per-agent Docker `--internal` network; bottles don't share state or talk to each other.
 - **Provider templates (Claude, Codex)** — `Dockerfile.claude` / `Dockerfile.codex`, or a bottle-supplied Dockerfile. Claude auth via long-lived OAuth token; Codex via opt-in host device-auth forwarding.
 - **gVisor auto-detect** — on Linux hosts where `runsc` is registered with Docker, every bottle launches under it for a userspace syscall barrier; no manifest config required.
-- **Apple Container backend (macOS default when available)** — runs the agent and sidecar bundle with Apple's `container` CLI, using a host-only agent network plus a separate sidecar egress network.
-- **Smolmachines backend** — runs the agent in a libkrun micro-VM while the sidecar bundle stays in Docker. TSI and smolmachines DNS filtering close the raw DNS exfiltration gap that exists in the legacy Docker backend.
-- **Legacy Docker backend** — still available for examples, CI, and hosts without Apple Container via `BOT_BOTTLE_BACKEND=docker` or `--backend=docker`.
+- **Smolmachines backend (macOS)** — opt-in `BOT_BOTTLE_BACKEND=smolmachines` runs the agent in a libkrun micro-VM with the sidecar bundle still in Docker.
 
 ## Architecture
 
-On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a sidecar bundle attached to both that internal network and a NAT egress network. The agent gets HTTP(S)_PROXY and CA bundle env vars pointing at the sidecar's internal-network IP, so HTTP/HTTPS traffic flows through the sidecar instead of direct egress. `bottle.git` / git-gate is intentionally deferred on this backend until a safe Apple Container key-delivery path exists.
-
-On the smolmachines backend, a bottle is an agent micro-VM plus a Docker sidecar bundle for egress, git-gate, and supervise. The VM reaches the sidecars through a per-bottle loopback alias allowed by TSI; smolmachines handles DNS filtering below the guest OS.
-
-On the legacy Docker backend, the same logical bottle is two containers per agent: an `agent` container and a `sidecars` container. They share a per-agent Docker `--internal` network; the agent has no default route off-box.
-
-The Docker topology looks like this:
+A bottle is two containers per agent: an `agent` container, and a `sidecars` container that bundles egress + git-gate + supervise behind a Python init supervisor. They share a per-agent Docker `--internal` network; the agent has no default route off-box.

 ## Quickstart
 
-On compatible macOS hosts, the default backend requires Apple's `container` CLI and does not require Docker. The smolmachines backend requires Docker on the host for the sidecar bundle plus smolvm. The legacy Docker backend requires Docker. Claude bottles also need a long-lived Claude Code OAuth token (`claude setup-token`) exported as `BOT_BOTTLE_CLAUDE_OAUTH_TOKEN`.

-# PRD 0057: Promote smolmachines to default backend; convert Docker to example-only
-
-- **Status:** Active
-- **Author:** didericis
-- **Created:** 2026-06-06
-- **Issue:** #206
-
-## Summary
-
-Make smolmachines the default bot-bottle backend and demote Docker to an example-only configuration. This closes the DNS sinkhole gap that exists in the Docker backend: the mitmproxy egress addon intercepts HTTP(S) but cannot see raw UDP port-53 DNS queries, so an agent can exfiltrate data via DNS tunnelling without the egress guard seeing it. The smolmachines backend eliminates this gap at the VMM layer — DNS filtering is built in and the agent container cannot bypass it.
-
-## Problem
-
-The current default backend is Docker. The egress addon (PRDs 0052/0053) intercepts HTTPS and scans request/response surfaces, but it is an HTTP proxy: raw UDP/TCP port-53 DNS queries go to the OS resolver and never pass through it. An agent can encode secrets as base32 or hex subdomains in a DNS query (`<encoded>.attacker.com`) and exfiltrate them silently.
-
-The smolmachines backend already solves this: its Transport Socket Interface (TSI) enforces a CIDR allowlist at the VMM layer, and DNS is handled via vsock port 6002 — the guest's `/etc/resolv.conf` points at `127.0.0.1`, and a guest-side DNS proxy tunnels queries over vsock to the host, which returns NXDOMAIN for anything not on the allowlist. The agent cannot bypass this by hardcoding IPs or by configuring an alternate resolver, because both mechanisms are enforced below the guest OS.
-
-Docker has no equivalent. Adding dnsmasq to the Docker backend would close the gap at some cost (dnsmasq sidecar, iptables `NET_ADMIN`, per-launch config generation), but it is the wrong direction if smolmachines supersedes Docker anyway.
-
-## Goals / Success Criteria
-
-- `BOT_BOTTLE_BACKEND` defaults to `smolmachines` when not set.
-- The existing Docker backend remains functional (not removed) but is no longer the default and is documented as legacy/example-only.
-- Example bottles (`examples/bottles/`) reference smolmachines, not Docker.
-- `AGENTS.md` documents the backend choice and the DNS gap closure.
-- Existing Docker-backed integration tests continue to pass; they select Docker explicitly via `BOT_BOTTLE_BACKEND=docker` rather than relying on the default.
-
-## Non-goals
-
-- Removing the Docker backend or its tests.
-- Implementing a dnsmasq layer for the Docker backend (closed by this change; not needed on the default path).
-- Iptables / `NET_ADMIN` work for Docker (deferred).
-- Subdomain-depth filtering for allowlisted zones (documented residual gap; tracked separately per the issue).
-
-## Design
-
-### Default backend change
-
-`bot_bottle/backend/__init__.py`, line ~440:
-
-```python
-# Before
-resolved = name or os.environ.get("BOT_BOTTLE_BACKEND") or "docker"
-
-# After
-resolved = name or os.environ.get("BOT_BOTTLE_BACKEND") or "smolmachines"
-```
-
-### DNS gap closure (how smolmachines handles it)
-
-When the smolmachines backend launches an agent VM:
-
-1. The VM's network device uses TSI (`--allow-host` / `--allow-cidr` flags), which enforces a CIDR allowlist at the VMM layer. The guest cannot dial IPs outside the allowlist even with raw sockets.
-2. The guest's `/etc/resolv.conf` is set to `127.0.0.1`; a guest-side DNS proxy relays queries over vsock port 6002 to the host.
-3. The host-side DNS filter returns NXDOMAIN for any hostname not in the allowlist derived from `egress.routes` in the bottle manifest.
-
-This means DNS exfiltration via unknown subdomains is blocked by NXDOMAIN before the query leaves the host, and even if the agent hardcoded the IP of an attacker-controlled server, TSI would drop the packet at the VMM layer.
-
-**Residual gap:** if the attacker controls a subdomain of an allowlisted zone (e.g., a legitimate zone like `api.anthropic.com` that the attacker can inject into via a separate compromise), DNS queries for that subdomain would be forwarded. This is accepted and documented.
-
-### Example bottles
-
-Update `examples/bottles/dev.md` and `examples/bottles/claude.md` to remove Docker-specific notes and reference smolmachines as the runtime.
-
-### Integration test migration
-
-Tests that exercise the Docker backend explicitly should set `BOT_BOTTLE_BACKEND=docker` rather than relying on the default. Tests that are backend-agnostic continue to use whatever `BOT_BOTTLE_BACKEND` is set to (defaulting to smolmachines in the test environment if available).
-
-## Resolved questions
-
-- **TSI + egress proxy loopback.** The implementation uses a per-bottle loopback alias rather than broad `127.0.0.1` passthrough. The smolmachines launch integration test now asserts that the guest receives proxy env vars on a `127.x` alias, can reach an allowlisted host through the proxy, cannot reach the same host directly with proxy vars unset, and cannot reach a non-allowlisted host through the proxy.
-- **smolmachines availability check.** The smolmachines preflight error points operators at the smolvm installer and explicitly suggests `BOT_BOTTLE_BACKEND=docker` / `--backend=docker` for legacy Docker-backed runs.

-# PRD 0058: Add built-in Pi agent provider
-
-- **Status:** Active
-- **Author:** codex
-- **Created:** 2026-06-09
-- **Issue:** #221
-
-## Summary
-
-Add `pi` as a built-in `agent_provider.template`. The provider runs the Pi
-coding-agent CLI, provisions its agent config under `~/.pi/agent`, and writes a
-provider settings file that targets an unauthenticated Ollama-compatible server.
-
-The default settings assume an Ollama server at `http://ollama:11434/v1`, using
-the `openai-completions` API with a dummy API key because Ollama ignores it.
-Users can override the provider id, base URL, model list, API key, API-key env
-reference, API type, and compatibility flags through a new
-`agent_provider.settings` object.
-
-## Problem
-
-bot-bottle currently ships Claude and Codex as built-in agent providers. Pi is a
-useful third harness, but using it today requires a custom provider plugin and a
-custom image. That repeats boilerplate for prompt copying, skill copying,
-provider config, and runtime registration.
-
-Pi's local-model path is also easy to misconfigure: its custom-model docs require
-`~/.pi/agent/models.json`, an API entry, at least one model id, and a dummy
-`apiKey` for Ollama even though the server does not authenticate. bot-bottle
-should generate that shape consistently.
-
-## Goals / Success Criteria
-
-- `agent_provider.template: pi` is accepted as a built-in provider.
-- `bot_bottle/contrib/pi/` provides a Pi image and `PiAgentProvider`.
-- Pi receives the bot-bottle prompt at `~/.bot-bottle-prompt.txt` and starts in
-  print-mode prompt delivery like Codex.
-- Pi skills are copied into `~/.pi/agent/skills/<name>/`.
-- Pi provider settings are configurable from the bottle manifest via
-  `agent_provider.settings`.
-- The default Pi provider settings configure an unauthenticated Ollama-compatible
-  server.
-- Unit tests cover manifest parsing, runtime selection, plan generation, prompt,
-  skills, and provider provisioning.
-
-## Non-goals
-
-- Managing or launching an Ollama server.
-- Authenticating to Ollama or any remote Pi provider.
-- Forwarding host Pi credentials.
-- Implementing Pi extensions or MCP registration.
-- Changing Claude or Codex provider behavior.
-
-## Design
-
-### Manifest
-
-Extend `agent_provider` with an optional `settings` object. It is currently only
-supported for built-in `pi`.
-
-Supported keys:
-
-- `base_url`: string, defaults to `http://ollama:11434/v1`
-- `provider`: string, defaults to `ollama`
-- `api`: string, defaults to `openai-completions`
-- `api_key`: string, defaults to `ollama`
-- `api_key_env`: string, optional host env var name for egress auth injection
-- `models`: non-empty array of strings, defaults to `["qwen2.5-coder:7b"]`
-- `context_window`: positive integer, defaults to `4096`; this is the Ollama
-  runtime context, and bot-bottle subtracts `max_tokens` before writing Pi's
-  `contextWindow` so output space is reserved
-- `max_tokens`: positive integer, defaults to `1024`
-- `max_tokens_field`: `max_tokens` or `max_completion_tokens`, defaults to
-  `max_tokens`
-- `supports_developer_role`: boolean, defaults to `false`
-- `supports_reasoning_effort`: boolean, defaults to `false`
-
-The snake-case manifest keys are converted into Pi's JSON field names:
-`baseUrl`, `apiKey`, `contextWindow`, `maxTokens`,
-`supportsDeveloperRole`, and `supportsReasoningEffort`. `context_window`
-describes the server's total context; Pi's `contextWindow` receives
-`context_window - max_tokens` because Pi uses it as an input compaction target.
-
-`api_key` and `api_key_env` are mutually exclusive. When targeting a hosted
-provider through bot-bottle's egress sidecar, omit `api_key` and set
-`api_key_env` to the host env var that holds the API key. The generated
-`models.json` receives only an `egress-placeholder` API key, and the egress
-route injects the real `Authorization` header from the sidecar env. For example,
-OpenRouter can use provider id `openrouter` with
-`api_key_env: OPENROUTER_API_KEY`, keeping the key out of the agent env and
-`models.json`.
-
-### Provider
-
-`PiAgentProvider.provision_plan` writes `models.json` into the per-launch state
-directory and returns an `AgentProvisionPlan` that copies it to
-`~/.pi/agent/models.json`. The provider also declares an unauthenticated egress
-route for the configured base URL host so the egress layer can allow the Ollama
-endpoint.
-
-The Pi runtime uses:
-
-- `command="pi"`
-- `prompt_mode="append_system_prompt"`
-- `image="bot-bottle-pi:latest"`
-- `bypass_args=()`
-- `resume_args=()`
-- `remote_control_args=()`
-
-The Dockerfile installs `@earendil-works/pi-coding-agent` globally from npm and
-keeps the same Debian/node base shape as the existing provider images.
-
-### Supervise MCP
-
-Pi does not have built-in MCP support in the current public docs, so
-`provision_supervise_mcp` is a no-op. This keeps Pi bottles launchable with
-`supervise: true` while preserving the explicit non-goal of implementing Pi
-extensions.
-
-## Merge rule(s)
-
-This PR can merge when the focused unit tests pass and the PRD status is flipped
-from Draft to Active in the final implementation commit.

-## Summary
-
-Add a `macos-container` backend that integrates Apple's `container`
-CLI as a host runtime on macOS. The shipped slices register the
-backend, implement reusable host primitives (`build`, `exec`, `cp`,
-image inspection, cleanup, active enumeration), make launch runnable
-with the proven two-network sidecar topology, and add real-runtime
-coverage without weakening bot-bottle's sidecar egress model.
-
-## Problem
-
-bot-bottle currently has two local execution paths:
-
-- `docker`, which runs the whole bottle topology through Docker
-  Compose.
-- `smolmachines`, which runs the agent in smolvm but still depends on
-  Docker for the sidecar bundle and image-building pipeline.
-
-Issue #220 explored removing Docker as a host dependency. A follow-up
-review comment verified that smolvm can publish guest ports back to
-host loopback and that another smolvm guest can reach that service
-through the existing per-bottle loopback alias plus `--allow-cidr`
-path. That keeps the VM-contained sidecar direction viable and rejects
-the host-process sidecar fallback.
-
-Apple's `container` CLI is another macOS-native way to run OCI images
-as lightweight Linux VMs. Its current command surface includes
-Docker-like `build`, `run`, `exec`, `cp`, port publishing, image
-inspection, and user-defined networks. That makes it a plausible local
-backend, but it does not remove the need to preserve bot-bottle's
-sidecar enforcement property: the agent must not have a direct egress
-path around the egress sidecar.
-
-## Goals / Success Criteria
-
-- `--backend=macos-container` and
-  `BOT_BOTTLE_BACKEND=macos-container` are accepted by the existing
-  backend selector.
-- Compatible macOS hosts default to `macos-container` when
-  `BOT_BOTTLE_BACKEND` and `--backend` are both unset.
-- Backend availability is true only on macOS hosts with `container` on
-  `PATH`.
-- The backend has tested wrappers for Apple Container image build,
-  image inspection, container `exec`, container `cp`, cleanup, and
-  active-agent enumeration.
-- Full launch uses a host-only internal network for the agent and a
-  separate NAT egress network for the sidecar bundle.
-- The agent container does not attach to the egress network. It reaches
-  allowed outbound hosts through HTTP(S)_PROXY pointing at the
-  sidecar's internal-network IP.
-- `bottle.git` / git-gate bottles fail loudly on this backend until a
-  safe Apple Container key-delivery path exists.
-- Real-runtime integration coverage is present and guarded by macOS and
-  Apple Container availability.
-
-## Non-goals
-
-- Do not remove or deprecate the Docker backend.
-- Do not remove or deprecate the smolmachines backend.
-- Do not run sidecar daemons as host processes.
-- Do not launch a degraded backend where the agent can bypass the
-  egress sidecar through direct network access.
-- Do not require Docker Desktop as part of the macOS Container backend.
-
-## Design
-
-### Backend name
-
-The selectable backend name is `macos-container`. The Python package
-uses `bot_bottle.backend.macos_container` because module names cannot
-contain hyphens.
-
-### Availability and preflight
-
-`MacosContainerBottleBackend.is_available()` returns true only when:
-
-- `platform.system() == "Darwin"`
-- `container` is discoverable on `PATH`
-
-`prepare()` calls `require_container()`, which produces a concrete
-install pointer and rejects non-macOS hosts.
-
-### Implemented primitives
-
-The backend owns an Apple Container wrapper module instead of reusing
-Docker wrappers. The wrapper maps bot-bottle's backend needs to
-Apple's CLI:
-
-| bot-bottle need | Apple Container command |
-|---|---|
-| Build provider image | `container build -t <ref> [-f Dockerfile] <context>` |
-| Run agent commands | `container exec [--interactive --tty] <id> ...` |
-| Copy files into guest | `container cp <host> <id>:<path>` |
-| Inspect image identity | `container image inspect <ref>` |
-| Cleanup stale containers | `container delete --force <id>` |
-| Cleanup stale networks | `container network delete <name>` |
-| Active enumeration | `container list --quiet` |
-
-The bottle handle mirrors `DockerBottle`: it builds a host argv for
-foreground agent execution, pipes shell snippets through stdin for
-`Bottle.exec`, and exposes `cp_in` for provisioning.
-
-### Launch topology
-
-`launch()` uses Apple Container's two-network topology:
-
-- create a host-only internal network for the bottle;
-- create a normal NAT egress network for the sidecar bundle;
-- start the sidecar bundle attached to the egress network first and the
-  internal network second;
-- discover the sidecar's internal-network IPv4 address from
-  `container inspect`;
-- start the agent attached only to the internal network, with
-  HTTP_PROXY / HTTPS_PROXY / lowercase proxy vars pointing at the
-  sidecar IP and egress port.
-
-This keeps the agent off the outbound network while preserving the
-proxy-env contract that existing agent tooling already honors. The
-integration smoke also removes the proxy env in-guest and confirms
-direct egress fails.
-
-### Deferred git-gate support
-
-Apple Container currently rejects single-file bind mounts, and
-`container cp` into a stopped container is not available. Starting the
-container earlier would allow `container cp` into a running container,
-but it would also mean delivering SSH private key material into a live
-sidecar before the git-gate daemon is ready to own it. Mounting broad
-host SSH directories is not acceptable.
-
-For this PRD, `bottle.git` / git-gate support is explicitly deferred on
-the `macos-container` backend. Bottles with git-gate upstreams fail
-loudly and should use `docker` or `smolmachines` until a narrower key
-delivery design lands.
-
-## Implementation chunks
-
-1. Register `macos-container`, add availability/preflight, bottle
-   handle, utility wrappers, cleanup, active enumeration, unit tests,
-   and this PRD.
-2. Spike Apple Container networking against real macOS 26 hosts:
-   repeated `--network`, internal network egress behavior, published
-   loopback reachability from another container, DNS behavior, and
-   labels/JSON output stability.
-3. Implement launch once the enforcement shape is proven. Reuse the
-   existing sidecar bundle image and daemon subset env contract where
-   possible.
-4. Add real-runtime integration tests guarded by `container` presence
-   and macOS version.
-5. Consider moving smolmachines sidecar/image-building work to
-   VM-contained or Apple Container-backed execution only after the
-   `macos-container` launch path is trustworthy.
-
-## Testing Strategy
-
-- Unit tests cover backend registration through `known_backend_names`.
-- Unit tests cover availability/preflight behavior without requiring
-  macOS.
-- Unit tests cover `MacosContainerBottle` command construction and
-  stdin-based shell execution.
-- Unit tests cover cleanup and active enumeration parsing.
-- Unit tests cover launch argv/env construction, sidecar mount
-  staging, sidecar IP parsing, and git-gate rejection.
-- Integration tests run on macOS hosts with Apple Container installed
-  and verify that egress cannot bypass the sidecar. They also preflight
-  Apple Container BuildKit DNS because image builds must resolve
-  package mirrors before a launch smoke can be meaningful. The backend
-  probes the running builder before image builds and leaves it alone
-  when its current resolver works. If the probe fails, or if the
-  operator explicitly sets `BOT_BOTTLE_MACOS_CONTAINER_DNS`, the backend
-  restarts the Apple Container builder with the configured DNS server.
-  Without an explicit override, that server is discovered from the
-  host's directly reachable IPv4 resolver before falling back to a
-  public resolver.

-
-Issue: https://gitea.dideric.is/didericis/bot-bottle/issues/230
-
-## Summary
-
-Apple Container 1.0.0 on macOS 26 can support the core two-network
-sidecar shape, but not as a drop-in Docker Compose clone.
-
-The viable shape is:
-
-- agent container on one `--internal` host-only network;
-- sidecar bundle container on both the NAT egress network and the
-  host-only agent network;
-- sidecar network flags ordered with the NAT network first, because
-  Apple Container chooses the first network as the default route;
-- explicit DNS on the sidecar, because the tested NAT gateway routed
-  packets but did not resolve DNS;
-- agent talks to sidecar by the sidecar's host-only-network IP, not by
-  container name or host-published loopback alias.
-
-This is enough to unblock a cautious `macos-container` launch spike if
-the backend records inspect-derived IPs and avoids depending on Docker
-Compose-style aliases. It is not enough to reuse the Docker backend's
-service-name assumptions unchanged.

-Repeated `--network` flags are accepted. With the agent network first,
-the sidecar got two interfaces but the default route pointed at the
-host-only gateway, so egress failed:

-
-## Answers
-
-### 1. Does `container network create --internal` prevent outbound internet access?
-
-Yes in this run. `--internal` produced a `hostOnly` network. An
-internal-only agent had a default route to the host-only gateway, but
-could not ping `1.1.1.1` and could not resolve or fetch
-`https://example.com`.
-
-### 2. Can `container run` attach one container to multiple networks?
-
-Yes. Repeated `--network` flags produced multiple interfaces and the
-inspect JSON preserved both network attachments.
-
-Important caveat: network order matters. The first network became
-`eth0`, supplied the default route, and supplied `/etc/resolv.conf`.
-For a sidecar that needs internet egress, put the NAT network first and
-the internal agent network second.
-
-### 3. Can the sidecar bundle sit on both an internal agent network and an egress-capable network?
-
-Yes. The sidecar had a NAT interface and a host-only interface. With the
-NAT network first and explicit DNS, it could fetch `https://example.com`
-while the agent on only the host-only network could not.
-
-### 4. Can Apple Container provide stable network aliases or service discovery equivalent to Docker Compose aliases?
-
-Not by default in this run. The agent could not resolve
-`bb-spike-230-sidecar` or `bb-spike-230-sidecar-alias`, even though
-those were the container names and hostnames in inspect output. The
-agent could reach the sidecar by the sidecar's host-only-network IP.
-
-The backend should not assume Docker Compose-style aliases. It should
-read the sidecar's host-only IP from `container inspect` and inject
-that concrete endpoint into the agent environment/config, or run a
-small internal DNS/hosts-file setup as an explicit backend feature.
-
-### 5. Can a published sidecar port bound to a per-bottle loopback alias be reached from another Apple Container guest and constrained to that alias?
-
-Host-side alias binding works and is constrained on the host:
-`127.0.0.31:18080` reached the sidecar, while `127.0.0.1:18080` failed.
-
-Guest-to-host-published-loopback did not work. From the agent,
-`192.168.128.1:18080` and `127.0.0.31:18080` both failed. For
-agent-to-sidecar traffic, use the sidecar's internal network IP rather
-than a host-published loopback alias.
-
-### 6. What structured output is available for robust enumeration and cleanup?
-
-Confirmed structured output:
-
-- `container list --all --format json`
-- `container inspect <container...>` as JSON
-- `container image inspect <image...>` as JSON
-- `container network list --format json`
-- `container network inspect <network...>` as JSON
-- `container system status --format json`
-- `container system version --format json`
-
-Useful fields observed:
-
-- containers: `id`, `configuration.labels`,
-  `configuration.networks`, `configuration.publishedPorts`,
-  `status.state`, `status.networks[].network`,
-  `status.networks[].ipv4Address`, `status.networks[].ipv4Gateway`;
-- networks: `id`, `configuration.name`, `configuration.labels`,
-  `configuration.mode`, `status.ipv4Gateway`, `status.ipv4Subnet`;
-- images: `id`, `configuration.name`, `configuration.descriptor`,
-  `variants[].platform`, `variants[].size`.
-
-### 7. Are labels supported on containers and networks enough to replace prefix-only discovery?
-
-Labels are present in container and network inspect/list JSON, so they
-are sufficient as metadata if the backend lists resources and filters
-client-side. I did not find or validate a server-side label filter for
-`container list` or `container network list`.
-
-## Recommendation
-
-Proceed with a narrow `macos-container` launch prototype, but encode
-the Apple Container-specific constraints directly:
-
-- create one host-only agent network and one NAT egress network per
-  bottle;
-- start the sidecar bundle with `--network <egress>` before
-  `--network <agent>`;
-- set sidecar DNS explicitly, ideally from the bottle/host policy
-  rather than hardcoding a public resolver;
-- start the agent only on the host-only network;
-- discover the sidecar's host-only IP from `container inspect` and pass
-  concrete URLs to the agent;
-- use host loopback publishing only for host-to-sidecar access, not
-  guest-to-sidecar access;
-- enumerate and clean up by labels plus name prefixes until/unless the
-  CLI adds label filters.
-
-Do not implement the backend as a direct clone of Docker Compose
-service aliases. That assumption failed in this run.

-# Apple Container transparent egress spike
-
-Issue: https://gitea.dideric.is/didericis/bot-bottle/issues/230#issuecomment-1994
-
-## Summary
-
-Transparent egress is mechanically possible on Apple Container 1.0.0,
-but it is not a free property of the platform and it is not a drop-in
-replacement for `HTTP_PROXY` yet.
-
-The spike proved two separate things:
-
-- Plain routing/NAT works if the sidecar has `CAP_NET_ADMIN`, IP
-  forwarding, and masquerade rules, and if the agent default route is
-  changed to the sidecar's host-only-network IP.
-- Transparent mitmproxy interception works if the sidecar redirects
-  agent-facing TCP 80/443 traffic to `mitmdump --mode transparent`.
-  Direct HTTP was logged by mitmproxy. Direct HTTPS reached mitmproxy;
-  it failed with normal certificate verification until the client
-  skipped verification, which is consistent with bot-bottle's existing
-  requirement that agents trust the sidecar CA.
-- Running DNS on the sidecar and pointing the agent at the sidecar's
-  host-only IP also works. This is cleaner than relying on forwarded
-  UDP DNS to a public resolver and gives the backend a natural place to
-  enforce or observe DNS policy.
-
-The hard blocker is agent routing. Apple Container 1.0.0 exposes no
-documented `--network` gateway option. An ordinary agent container
-cannot replace its default route:
-
-```console
-$ container exec bb-spike-230t-agent sh -c \
-  'ip route replace default via 192.168.128.2 dev eth0; ip route'
-default via 192.168.128.1 dev eth0
-192.168.128.0/24 dev eth0 scope link  src 192.168.128.3
-ip: RTNETLINK answers: Operation not permitted
-```
-
-The successful route-through-sidecar tests used `--cap-add
-CAP_NET_ADMIN` on the agent so the route could be changed after start.
-That is not an acceptable final design by itself: it expands the
-agent's kernel-facing privilege and lets the agent mutate its own
-network namespace. A production design needs either a backend-owned
-init/shim that sets the route then drops privilege in a way the agent
-cannot regain, a platform-supported gateway option, or a different
-network attachment layer.

-Networks:
-
-```bash

-  --internal \
-  --label bot-bottle.spike=transparent-egress
-
-container network create bb-spike-230t-egress \
-  --label bot-bottle.spike=transparent-egress
-```
-
-Sidecar, dual-homed with NAT first:
-
-```bash
-container run --name bb-spike-230t-sidecar \
-  --label bot-bottle.spike=transparent-egress \
-  --network bb-spike-230t-egress \
-  --network bb-spike-230t-agent \
-  --dns 1.1.1.1 \
-  --detach docker.io/alpine:latest sleep 1800
-```
-
-Agent, host-only network:
-
-```bash
-container run --name bb-spike-230t-agent \
-  --label bot-bottle.spike=transparent-egress \
-  --network bb-spike-230t-agent \
-  --detach docker.io/alpine:latest sleep 1800
-```
-
-Observed sidecar addresses:
-
-```console
-eth0 192.168.66.2/24    # NAT egress network
-eth1 192.168.128.2/24   # host-only agent network
-default via 192.168.66.1 dev eth0
-nameserver 1.1.1.1
-```
-
-Observed agent baseline:
-
-```console

-default via 192.168.128.1 dev eth0
-nameserver 192.168.128.1
-wget: bad address 'pypi.org'
-```
-
-That confirms the previous spike's baseline: sidecar can egress, agent
-cannot egress directly.
-
-## Plain NAT Test
-
-Relaunch sidecar and agent with `CAP_NET_ADMIN`:
-
-```bash
-container run --name bb-spike-230t-sidecar \
-  --label bot-bottle.spike=transparent-egress \
-  --network bb-spike-230t-egress \
-  --network bb-spike-230t-agent \
-  --dns 1.1.1.1 \
-  --cap-add CAP_NET_ADMIN \
-  --detach docker.io/alpine:latest sleep 1800
-
-container run --name bb-spike-230t-agent \
-  --label bot-bottle.spike=transparent-egress \
-  --network bb-spike-230t-agent \
-  --cap-add CAP_NET_ADMIN \
-  --detach docker.io/alpine:latest sleep 1800
-```
-
-Configure sidecar forwarding:
-
-```bash
-container exec bb-spike-230t-sidecar sh -c '
-  apk add --no-cache iptables iproute2
-  sysctl -w net.ipv4.ip_forward=1
-  iptables -t nat -A POSTROUTING -s 192.168.128.0/24 -o eth0 -j MASQUERADE
-  iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT
-  iptables -A FORWARD -i eth0 -o eth1 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
-'
-```
-
-Point the agent at the sidecar:
-
-```bash
-container exec bb-spike-230t-agent sh -c '
-  ip route replace default via 192.168.128.4 dev eth0
-  printf "nameserver 1.1.1.1\n" > /etc/resolv.conf
-'
-```
-
-Normal direct PyPI fetch from the agent, with no proxy variables set:
-
-```bash
-container exec bb-spike-230t-agent sh -c '
-  for v in HTTP_PROXY HTTPS_PROXY http_proxy https_proxy ALL_PROXY all_proxy; do
-    if [ -n "$(printenv "$v")" ]; then echo "$v=SET"; fi
-  done
-  wget -T 10 -O- https://pypi.org/simple/pip/ | head -c 120
-'
-```
-
-Observed:
-
-```console
-Connecting to pypi.org (151.101.0.223:443)
-<!DOCTYPE html>
-<html lang="en">
-  <head>
-    <meta name="pypi:repository-version" content="1.4">
-```
-
-Sidecar NAT counters increased:
-
-```console
-POSTROUTING MASQUERADE 3 packets / 168 bytes
-FORWARD eth1 -> eth0 22 packets / 2806 bytes
-FORWARD eth0 -> eth1 29 packets / 54781 bytes
-```
-
-Verdict: plain transparent routing through the sidecar works, but this
-is only NAT. It does not apply bot-bottle's existing route allowlist,
-authorization stripping/injection, or DLP logic.
-
-## Transparent Mitmproxy Test
-
-The current sidecar launcher uses explicit proxy mode:
-
-```sh
-MODE="--mode regular@9099"
-exec mitmdump $CONFDIR_FLAG $MODE $LISTEN_HOST_FLAG $TRUST_FLAG -s /app/egress_addon.py
-```
-
-So transparent egress needs a launcher mode change plus iptables
-redirects.
-
-Run a test mitmproxy container:
-
-```bash
-container run --name bb-spike-230t-mitm \
-  --label bot-bottle.spike=transparent-egress \
-  --network bb-spike-230t-egress \
-  --network bb-spike-230t-agent \
-  --dns 1.1.1.1 \
-  --cap-add CAP_NET_ADMIN \
-  --detach mitmproxy/mitmproxy:11.1.3 \
-  sh -c 'apt-get update >/tmp/apt.log &&
-    apt-get install -y --no-install-recommends iptables iproute2 >>/tmp/apt.log &&
-    echo 1 > /proc/sys/net/ipv4/ip_forward &&
-    iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 8080 &&
-    iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 443 -j REDIRECT --to-port 8080 &&
-    mitmdump --mode transparent@8080 --set showhost=true --set ssl_insecure=true --set confdir=/tmp/mitm -v'
-```
-
-The container listened successfully:
-
-```console
-Transparent Proxy listening at *:8080.
-```
-
-It had an agent-facing address of `192.168.128.7`. Point the agent at
-it and set DNS:
-
-```bash
-container exec bb-spike-230t-agent sh -c '
-  ip route replace default via 192.168.128.7 dev eth0
-  printf "nameserver 1.1.1.1\n" > /etc/resolv.conf
-'
-```
-
-DNS also needs NAT/forwarding because only TCP 80/443 is redirected:
-
-```bash
-container exec bb-spike-230t-mitm sh -c '
-  iptables -t nat -A POSTROUTING -s 192.168.128.0/24 -o eth0 -j MASQUERADE
-  iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT
-  iptables -A FORWARD -i eth0 -o eth1 -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
-'
-```
-
-An alternative, and likely better, DNS shape is to run a DNS forwarder on
-the sidecar's host-only IP and point the agent at it. This was tested
-with `dnsmasq`:
-
-```bash
-container exec bb-spike-230t-mitm sh -c '
-  apt-get install -y --no-install-recommends dnsmasq
-  cat >/tmp/dnsmasq.conf <<EOF
-no-daemon
-listen-address=192.168.128.7
-bind-interfaces
-server=1.1.1.1
-log-queries
-log-facility=-
-EOF
-  (dnsmasq --conf-file=/tmp/dnsmasq.conf >/tmp/dnsmasq.log 2>&1 &)
-  sleep 1
-  ss -lunp | grep :53
-'
-```
-
-Observed:
-
-```console
-UNCONN 0 0 192.168.128.7:53 0.0.0.0:* users:(("dnsmasq",pid=515,fd=4))
-```
-
-Point the agent to sidecar DNS:
-
-```bash
-container exec bb-spike-230t-agent sh -c '
-  printf "nameserver 192.168.128.7\n" > /etc/resolv.conf
-  nslookup pypi.org
-'

-

-  'wget -T 10 -O- http://example.com | head -c 100'

-does for explicit proxy mode.
-
-## Answers
-
-### Can the sidecar become the agent network's default gateway?
-
-Not directly through Apple Container's documented CLI. The installed
-`container run --help` documents `--network
-<name>[,mac=XX:XX:XX:XX:XX:XX][,mtu=VALUE]`; it does not document a
-gateway option.
-
-The route can be changed after container start only if the agent has
-`CAP_NET_ADMIN`. Without it, `ip route replace default via <sidecar>`
-fails with `Operation not permitted`.
-
-### Can Apple Container support sidecar forwarding/NAT/transparent proxying?
-
-Yes. A dual-homed sidecar with `CAP_NET_ADMIN` can enable IP forwarding,
-set iptables NAT/forwarding rules, and route agent traffic out through
-the NAT network.
-
-Transparent mitmproxy interception also works with `PREROUTING`
-redirects to `mitmdump --mode transparent`.
-
-### What capabilities/custom image are required?
-
-At minimum:
-
-- sidecar needs `CAP_NET_ADMIN`;
-- sidecar image needs `iptables`/`iproute2` or equivalent nftables
-  tooling;
-- sidecar should run a DNS listener on its host-only IP, or otherwise
-  provide a controlled resolver path for the agent;
-- sidecar launcher needs a transparent mode variant;
-- agent route must be changed to the sidecar's host-only IP;
-- agent DNS should point to the sidecar DNS listener;
-- agent must trust the sidecar CA for HTTPS interception.
-
-The tested agent route mutation required agent `CAP_NET_ADMIN`, which
-should not be accepted as the final design without a privilege-dropping
-init/shim story.
-
-### Can host-level `pf` or vmnet rules replace agent route mutation?
-
-Not tested. The successful transparent paths did not use host `pf`;
-they used container-local routing and iptables. Host-level `pf` remains
-a possible escape hatch if Apple Container cannot set a custom gateway
-and we reject agent `CAP_NET_ADMIN`.
-
-### Can existing route policy and DLP semantics be preserved?
-
-Likely, but not fully validated in this spike. Mitmproxy transparent
-mode produced normal HTTP flows with correct `Host` values for both
-HTTP and HTTPS. The existing `egress_addon.py` hooks should still see
-`flow.request.pretty_host`, method, path, headers, and response bodies.
-
-But the current sidecar entrypoint only starts `mitmdump` in regular
-explicit-proxy mode. A real implementation must add a transparent mode
-launcher and then run the existing egress addon test suite against
-transparent flows.
-
-## Recommendation
-
-Do not switch `macos-container` to transparent egress yet, but keep it
-as a plausible implementation path.
-
-The next implementation spike should focus on removing the agent
-`CAP_NET_ADMIN` requirement. Acceptable options:
-
-- find or add an Apple Container-supported default-gateway setting;
-- start the agent through a tiny root init that sets route/DNS, drops
-  capabilities, and then execs the agent as the normal user;
-- include a sidecar DNS service and set the agent resolver to the
-  sidecar's host-only IP as part of that init/setup path;
-- avoid routing mutation by using host/vmnet-level packet redirection;
-- explicitly decide that route mutation is only a convenience layer and
-  keep explicit proxy env vars for v1.
-
-Bluntly: transparent egress is feasible, but not production-ready until
-the agent route can be controlled without leaving network-admin power in
-the agent runtime.
