docs: update forge PRD — orchestrator split, done signal, org targeting, forge env vars

Skill names become host/guest path segments interpolated into the
`bottle.exec` shell strings in each contrib provider's provision_skills.
They were validated only as strings, so a name with shell metacharacters
or path traversal could reach the command.

Layer two defenses:
  - Primary: reject any skill name that isn't kebab-case
    ([a-z][a-z0-9-]*) at manifest load, reusing the convention already
    enforced on bottle/agent filenames (new is_valid_entity_name helper
    in manifest_schema). Fails loud and early, protecting every consumer
    of the name — not just the exec call sites.
  - Failsafe: shlex.quote the interpolated skills_dir / dst paths in the
    claude, codex, and pi providers, so a future unvalidated field can't
    inject shell metacharacters even if it bypasses the load-time check.

 ## Features
 
-- **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.
+- **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-route token-match policy** — each egress route picks what happens when the outbound DLP catches a token via `dlp.outbound_on_match`: `supervise` (default) holds the request and surfaces it in `./cli.py supervise` for approval (an approved value is remembered for the life of the proxy); `redact` scrubs the value and forwards; `block` is a hard `403`. Cuts false-positive friction without weakening default-deny.
 - **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 is its own per-agent Docker `--internal` network; bottles don't share state or talk to each other.
+- **Parallel, isolated bottles** — each bottle runs in its own backend-owned isolation boundary; 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.
-- **Smolmachines backend (macOS)** — opt-in `BOT_BOTTLE_BACKEND=smolmachines` runs the agent in a libkrun micro-VM with the sidecar bundle still in Docker.
+- **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`.
 
 ## Architecture
 
-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.
+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.

+| `matches[].methods` | no | Array of HTTP method strings, e.g. `[GET, POST]`. |

+| `dlp.inbound_detectors` | no | `false` disables inbound scanning; list restricts to named detectors (`naive_injection_detection`). |
+| `dlp.outbound_on_match` | no | What to do when an outbound token is detected: `supervise` (default for manifest routes — hold for operator approval), `redact` (scrub the value and forward), or `block` (hard 403). Agent-provider routes (e.g. `api.anthropic.com`) default to `redact`. |
+| `git.fetch` | no | `true` permits smart HTTP clone/fetch (`git-upload-pack`) for this host. Push (`git-receive-pack`) remains blocked. |
+
+When an outbound DLP detector matches a token, the route's `dlp.outbound_on_match` policy decides what happens. Under the default `supervise`, the proxy queues an `egress-token-allow` proposal for the operator's `./cli.py supervise` TUI and holds the request open until it is answered (or `EGRESS_TOKEN_ALLOW_TIMEOUT_SECONDS`, default 300s, elapses — after which it fails closed). The operator never sees the raw token, only the host, method, path, and a redacted snippet; approving adds the value to an in-memory safelist for the life of the egress proxy. Under `redact`, the matched value is scrubbed from the body, headers, and path and the request is forwarded (failing closed if a match lands somewhere unredactable, like the hostname). Under `block` it stays a hard `403`. Structural blocks (CRLF injection) and not-in-allowlist host blocks are always hard `403`s regardless of policy.

+"""Host-side raw-mode wrapper for `container exec --interactive --tty`.
+
+Apple's `container exec --interactive --tty` does not set the host terminal to
+raw mode before starting its I/O relay.  Without raw mode the kernel line
+discipline buffers modifier-key escape sequences (e.g. Shift+Enter in
+modifyOtherKeys mode produces \\x1b[13;2~) until a carriage-return arrives, so
+they never reach Claude Code inside the container.
+
+This module sets the host terminal to raw mode, spawns the inner argv (the
+container exec command), and restores the original terminal attributes on
+exit.  When stdin is not a TTY (piped invocations, CI) it falls through to a
+bare subprocess.run so callers do not need to special-case non-interactive
+contexts.
+
+Usage (the `--` separator is the API contract — everything after it is the
+inner command):
+
+    python pty_forward.py -- container exec --interactive --tty <name> <cmd>

+"""Tiny logging wrappers. All output goes to stderr.
+
+Two capabilities layer onto the bare wrappers (issue #252):
+
+  - **Levels.** `debug` / `info` / `warn` / `error` carry an ordered
+    severity. Output is gated by `BOT_BOTTLE_LOG_LEVEL` (debug | info |
+    warn | error; default `info`). A message emits when its severity is
+    at or above the threshold, so `debug` is silent by default and
+    `error` always surfaces (nothing sits above it) — which keeps the
+    fatal `die` path visible regardless of the configured level.
+
+  - **Context.** Every wrapper takes an optional `context` mapping that
+    renders as a parseable ` [k=v ...]` suffix (keys sorted; values with
+    whitespace/quotes are quoted), so failures can be filtered and
+    correlated instead of being flat strings.
+
+With no `context` and the default level, output is byte-identical to the
+original `bot-bottle: <msg>` / `bot-bottle: warning: <msg>` /

+# ADR 0004: Risk-weighted coverage, not a single global target
+
+- **Status:** Accepted
+- **Date:** 2026-06-25
+- **Deciders:** didericis
+
+## Context
+
+bot-bottle is a security tool: it sandboxes agents, scans egress for
+secret exfiltration, strips credentials, and gates git pushes. A latent
+bug in that logic is expensive, so test coverage there genuinely
+matters. But the repo also contains code where coverage is a poor
+signal:
+
+- **Interactive entry-point shells** — `cli/init.py` (a `read_tty_line()`
+  prompt loop) and `cli/tui.py` (a curses picker). Their bodies are I/O;
+  a unit test has to fake the entire terminal conversation, so it
+  inflates the number without asserting behaviour that would otherwise
+  go unchecked.
+- **Subprocess / backend orchestration** — the docker / smolmachines /
+  macos-container backends shell out to `docker`, `container`, `smolvm`.
+  Mock-heavy unit tests here mostly re-assert the argv you already
+  wrote (the test passes whether or not the real teardown works), while
+  many of the missed *branches* are failure paths you cannot provoke
+  against a real daemon on cue.
+
+Chasing a single global percentage (e.g. 90%) pushes the most test
+effort onto the least safety-relevant code — exactly backwards — and
+invites performative tests written to colour a line rather than to catch
+a regression (Goodhart's law).
+
+## Decision
+
+Coverage is **risk-weighted**, measured over the **combined unit +
+integration** suites, with three rules:
+
+1. **Critical modules target ≥ 90%.** The security/logic core —
+   `egress_addon{,_core}.py`, `dlp_detectors.py`, `egress.py`,
+   `manifest*.py`, `git_gate.py`, `git_http_backend.py`, `supervise.py`,
+   `yaml_subset.py`, `bottle_state.py` — is Docker-independent and
+   unit-testable, so it carries the high bar. We ratchet toward 90% as
+   these modules are touched; new gaps in them are not acceptable.
+
+2. **Subprocess/backend orchestration is covered by the integration
+   suite, not omitted.** `scripts/coverage.sh` runs unit + integration
+   under one coverage measurement so these modules are scored where they
+   are actually exercised. They stay *visible* — hiding the code that
+   tears down sandboxes and wires networks is the one place we will not
+   omit.
+
+3. **Interactive entry-point shells are omitted** (`.coveragerc`), with a
+   rationale comment. This is the only sanctioned use of `omit` besides
+   `tests/*`.
+
+The forward-looking guard is a **diff-coverage gate**
+(`scripts/diff_coverage.py`): new/changed executable lines on a branch
+must be ≥ 90% covered. This catches regressions where they are
+introduced without forcing a back-fill crusade through legacy glue. The
+gate skips lines in omitted files (there is no coverage data for them),
+so the omit list cannot launder *new* logic into the dark: anything that
+needs real testing must live outside the interactive shells to be
+scored at all.
+
+The **global percentage is informational**, not a CI gate — it would
+otherwise be hostage to the CI runner's Docker availability and to the
+omit list.
+

+  regression in code we control, not noise from added CLI glue.
+- No incentive to write mock-the-mock tests for orchestration to defend
+  a global figure.
+- The omit list needs governance: an entry must be a genuinely
+  interactive shell, justified in the `.coveragerc` comment and here.
+  `cli/init.py` and `cli/tui.py` qualify; backend orchestration does

+  and their modules read low — accepted, because the *enforced* gates

+# 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.

+# PRD 0059: macOS Container backend
+
+- **Status:** Active
+- **Author:** Codex
+- **Created:** 2026-06-10
+- **Issue:** #220
+
+## 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.

+# PRD 0060: Commit bottle state to an image
+
+- **Status:** Active
+- **Author:** Claude
+- **Created:** 2026-06-20
+- **Issue:** #194
+
+## Summary
+
+Add a `commit` CLI command that freezes a running bottle's state to a
+resumable local artifact. Docker bottles are stored as Docker images;
+smolmachines bottles are stored as `.smolmachine` artifacts. Operators
+can then resume the bottle from that exact filesystem snapshot, or
+export the artifact to migrate work to a different host.
+
+## Problem
+
+When a long-running agent session is interrupted — by a host reboot, a
+network failure, or a planned infrastructure migration — the in-progress
+container state is lost. `cli.py resume` rebuilds the agent image from
+the Dockerfile and reprovi-sions the bottle, but that returns the guest
+to its initial state, not to wherever the agent was mid-task.
+
+There is no mechanism today to capture "what's installed / configured
+inside the running container right now" and make it reproducible. The
+`capability-block` flow writes a new Dockerfile and marks the bottle for
+resume, but that only applies when the agent itself has requested a
+capability change; it doesn't help the operator who wants to take a
+snapshot before a planned host reboot or hardware migration.
+
+## Goals / Success Criteria
+
+- `./cli.py commit [<slug>]` takes a snapshot of the running agent and
+  stores it as a local artifact.
+- Without a slug argument the command shows the same interactive picker
+  as `start` (the list of active slugs).
+- The committed artifact reference is stored in per-bottle state so
+  that the next `./cli.py resume <slug>` automatically uses the
+  snapshot instead of rebuilding from the Dockerfile.
+- `mark_preserved` is called so the state dir survives the normal
+  session-end cleanup.
+- A backend-specific export hint is printed so operators know how to
+  migrate the snapshot.
+- The command errors clearly on unsupported backends.
+
+## Non-goals
+
+- macOS-container backend support.
+- Automatic commit on agent exit.
+- Image push to a remote registry.
+- Storing the image tag in the manifest or sharing it between operators.
+
+## Design
+
+### Docker image tag
+
+`bot-bottle-committed-<slug>:latest` — namespaced under `bot-bottle-`
+to match existing image naming conventions; `committed` distinguishes it
+from the build-time image (`bot-bottle-claude:latest`) and the
+capability-block rebuild image (`bot-bottle-rebuilt-<identity>:latest`).
+
+### State storage
+
+A new plain-text file `committed-image` is added to the per-bottle state
+directory:
+
+```
+~/.bot-bottle/state/<identity>/
+    metadata.json
+    Dockerfile            (capability-block override; optional)
+    committed-image       (committed artifact reference; optional)
+    transcript/
+```
+
+`bottle_state.committed_image_path(identity)` returns the path.
+`write_committed_image` / `read_committed_image` are the read/write
+helpers, matching the existing `per_bottle_dockerfile` pattern. Docker
+stores a Docker tag in this file; smolmachines stores the absolute path
+to the committed `.smolmachine` artifact.
+
+### `commit` command
+
+```
+./cli.py commit [<slug>]
+```
+
+1. Resolve slug (arg or interactive picker from `enumerate_active_agents`).
+2. Check metadata and branch by backend.
+3. For Docker, derive container name `bot-bottle-<slug>` and run
+   `docker commit <container> bot-bottle-committed-<slug>:latest`.
+4. For smolmachines, derive machine name `bot-bottle-<slug>` and run
+   `smolvm pack create --from-vm <machine> -o ~/.bot-bottle/state/<slug>/committed-smolmachine`.
+5. Write the Docker image tag or smolmachine artifact path to
+   `~/.bot-bottle/state/<slug>/committed-image`.
+6. Call `mark_preserved(<slug>)` so the state dir survives session-end.
+7. Print the resume hint and a backend-specific export example.
+
+### Resume from committed image
+
+`bot_bottle/backend/docker/launch.py` already rebuilds the agent image
+at the top of the `launch` context manager. The change is a check
+immediately before that step:
+
+```python
+committed = read_committed_image(plan.slug)
+if committed and docker_mod.image_exists(committed):
+    info(f"using committed image {committed!r}")
+    plan = dataclasses.replace(
+        plan,
+        agent_provision=dataclasses.replace(plan.agent_provision, image=committed),
+    )
+else:
+    docker_mod.build_image(plan.image, _REPO_DIR, dockerfile=plan.dockerfile_path)
+```
+
+Replacing `agent_provision.image` propagates to `plan.image` (a
+property) and from there to the Compose spec renderer's `_agent_service`
+→ `image:` field, so the container boots from the committed snapshot.
+The build step is skipped entirely when a committed image is found and
+exists locally.
+
+If the committed image has been deleted from the local daemon (e.g.
+after `docker rmi` or a `docker system prune`), the launch falls back
+to a normal Dockerfile build, matching the pre-commit behavior.
+
+### Resume from committed smolmachine
+
+`bot_bottle/backend/smolmachines/launch.py` checks the committed
+reference before the normal Docker build -> pack cache path:
+
+```python
+committed = read_committed_image(plan.slug)
+if committed and Path(committed).is_file():
+    return Path(committed)
+return _ensure_smolmachine(plan.agent_image, dockerfile=plan.agent_dockerfile_path)
+```
+
+The returned path is passed to `smolvm machine create --from`, so the
+resumed VM boots from the committed snapshot. If the artifact has been
+deleted, launch falls back to the normal build and pack flow.
+
+## Testing strategy
+
+- Unit tests for `write_committed_image` / `read_committed_image` in
+  `tests/unit/test_bottle_state.py`, using the existing `_FakeHomeMixin`
+  pattern.
+- Unit tests for `commit_container` in `tests/unit/test_docker_util_image.py`,
+  mocking `subprocess.run` and asserting on the `docker commit` argv.
+- Unit tests for `cmd_commit` argument parsing, Docker commit,
+  smolmachines pack, and the unsupported backend error path, mocking
+  `enumerate_active_agents`, `commit_container`, and
+  `pack_create_from_vm`.
+- Unit tests for the launch-step committed-image branch: patch
+  `read_committed_image` to return a tag, patch `image_exists` to return
+  True, and assert that `build_image` is not called and `plan.image` is
+  overridden.
+- Unit tests for the smolmachines launch-step committed-artifact branch:
+  patch `read_committed_image` to return an existing path and assert the
+  normal `_ensure_smolmachine` path is skipped.

+# PRD 0061: Gitleaks inline suppression supervision
+
+- **Status:** Active
+- **Author:** codex
+- **Created:** 2026-06-10
+- **Issue:** #208
+
+## Summary
+
+Route every `# gitleaks:allow` inline suppression through the existing
+supervisor approval queue before git-gate forwards a push upstream. The
+annotation remains available for test fixtures and confirmed false positives,
+but it no longer lets an agent silently bypass the gate's secret scan.
+
+## Problem
+
+Gitleaks supports inline suppression comments. With the default behaviour,
+a pushed line that contains a secret-like value and `# gitleaks:allow` is
+ignored by gitleaks and accepted by git-gate. That is convenient for dummy
+credentials in tests, but it also gives an agent a one-line bypass for a real
+secret. Once the commit lands, the diff alone cannot prove whether the
+suppression was legitimate.
+
+## Goals / Success Criteria
+
+1. Git-gate continues to run the normal gitleaks scan for every incoming ref.
+2. After the normal scan passes, git-gate runs a second scan with
+   `--ignore-gitleaks-allow` and a JSON report so suppressed findings become
+   visible.
+3. If that second scan reports no suppressed findings, the push proceeds
+   unchanged.
+4. If it reports suppressed findings, git-gate creates a `gitleaks-allow`
+   supervisor proposal containing the ref, file path, line number, rule,
+   commit, and flagged line for each finding.
+5. The push proceeds only when the supervisor explicitly approves the
+   proposal; rejection, malformed responses, missing supervisor configuration,
+   and timeout all refuse the push.
+6. The supervisor TUI requires a reason when approving a `gitleaks-allow`
+   proposal, so the audit trail records whether the approval was for a test
+   fixture or a false positive.
+
+## Non-goals
+
+- Replacing gitleaks or changing the main secret-detection rule set.
+- Removing support for `# gitleaks:allow`.
+- Automatically classifying fixture files or false positives.
+- Adding new supervisor transport or authentication mechanisms.
+
+## Design
+
+### Git-gate flow
+
+`git_gate_render_hook()` emits a `supervise_gitleaks_allow` shell helper.
+For each incoming ref, git-gate first runs the existing gitleaks command. If
+that scan passes, it runs:
+
+```sh
+gitleaks git \
+  --log-opts="$log_opts" \
+  --no-banner \
+  --redact \
+  --ignore-gitleaks-allow \
+  --report-format=json \
+  --report-path="$report_file" \
+  --exit-code 0
+```
+
+The second pass keeps the push path non-interactive while producing a report
+of findings that would otherwise have been hidden by inline suppression.
+
+### Supervisor proposal
+
+When the JSON report contains findings, an embedded Python helper writes a
+proposal into `SUPERVISE_QUEUE_DIR` using the existing proposal schema. The
+proposal uses:
+
+- `tool: "gitleaks-allow"`
+- a text payload with the ref and each finding's file, line, rule, commit,
+  and redacted code line
+- a justification that tells the operator to approve only dummy test fixtures
+  or confirmed false positives
+
+Git-gate then waits for `<proposal-id>.response.json` for
+`SUPERVISE_GITLEAKS_ALLOW_TIMEOUT_SECONDS`, defaulting to 300 seconds.
+`approved` and `modified` responses allow the push; `rejected`, invalid
+responses, invalid timeout configuration, or timeout refuse it.
+
+### Supervisor UI
+
+`TOOL_GITLEAKS_ALLOW` is added to the supervisor tool registry. The curses
+supervisor renders the proposal as text and allows approval or rejection.
+Modification is unavailable for this proposal type because there is no file
+patch to apply. Approval from the TUI prompts for a non-empty reason and
+writes that reason to the response/audit path.
+
+### Tests
+
+Unit tests assert that the rendered git-gate hook includes the second gitleaks
+pass, supervisor queue fields, and fail-closed messages. Supervisor tests cover
+the new tool constant, proposal archiving, and the required TUI approval
+reason.

+# PRD 0062: Supervisor override for egress token blocks
+
+- **Status:** Active
+- **Author:** claude
+- **Created:** 2026-06-24
+- **Issue:** #261
+
+## Summary
+
+Give each egress route a policy for what happens when an outbound DLP detector
+matches a token, via `dlp.outbound_on_match: block | redact | supervise`
+(default `supervise`):
+
+- **`supervise`** (default) — route the block through the existing supervisor
+  approval queue instead of returning `403` immediately. The proxy holds the
+  request open until the operator approves or rejects it. On approval the
+  matched token is added to an in-memory "safe tokens" set so the request — and
+  any later request carrying the same token — flows through without
+  re-prompting.
+- **`redact`** — scrub the matched value(s) from the request and forward it,
+  no operator in the loop. For routes where a token-shaped value is noise the
+  upstream doesn't need (telemetry/log sinks). Fails closed if a match lands on
+  a surface redaction can't rewrite (the hostname).
+- **`block`** — the original hard `403`; never overridable. For routes where a
+  detected token must always stop.
+
+The motivating goal is reducing friction from false positives without weakening
+the default-deny posture: supervise keeps a human in the loop, redact is an
+explicit per-route opt-in, and block stays available for sensitive routes.
+
+## Problem
+
+The outbound DLP detectors (`token_patterns`, `known_secrets`) are
+deliberately aggressive: any string that looks like a credential is blocked
+before it leaves the bottle. That is the right default, but it produces false
+positives — a token-shaped value that is not actually a secret, or a credential
+the agent legitimately needs to send to a declared host. Today the only
+recovery is for the operator to notice the `egress DLP` 403 in the logs and
+hand-edit the route's `dlp.outbound_detectors`, which disables the detector for
+the whole route rather than allowing the one value.
+
+The operator has no in-the-loop signal that a token block happened and no
+fine-grained way to say "this specific value is fine."
+
+## Goals / Success Criteria
+
+1. An outbound DLP **token** block (a `ScanResult` carrying a matched secret
+   value) creates a supervisor proposal instead of an immediate `403`.
+2. The egress proxy holds the blocked request open, polling for the operator's
+   response up to a bounded timeout.
+3. The proposal shows the operator the host, method, path, the detector reason,
+   and a **redacted** context snippet — never the raw token value.
+4. On `approved`/`modified`, the matched token value is added to an in-memory
+   safe-tokens set and the request proceeds normally; later requests carrying
+   the same value skip the block.
+5. On `rejected`, timeout, malformed response, or missing supervisor wiring,
+   the request fails closed with the same `403` as today.
+6. Structural blocks that carry no token value (CRLF injection) and the
+   route-not-allowlisted / git blocks are unchanged — they stay hard `403`s and
+   keep their existing agent-driven `allow` / `egress-block` MCP path.
+7. The proxy event loop is not stalled while waiting: the wait is asynchronous,
+   so other flows keep being served.
+
+## Non-goals
+
+- Persisting the safe-tokens set across egress restarts. It lives in process
+  memory only; a restart re-prompts. (The issue explicitly defers persistence.)
+- Supervising inbound (prompt-injection) blocks or WebSocket frame blocks.
+  WebSocket frames still honour the safe-tokens set for already-approved values
+  but cannot wait for approval (there is no response surface after upgrade).
+- Generalising an approved secret across encodings. The safe-tokens set matches
+  the exact value the detector found.
+- Replacing the per-route `dlp.outbound_detectors` override. That remains the
+  way to turn a detector off wholesale.
+- Making `redact` the default. Silent redaction of a true false positive
+  corrupts legitimate data, so it is opt-in per route; `supervise` (human in
+  the loop) stays the default.
+
+## Scope
+
+### In scope
+
+The minimum cut that ships, in build order:
+
+1. **Core** — `ScanResult.matched`; thread `safe_tokens` through
+   `scan_outbound` / the token detectors; `build_token_allow_payload`.
+2. **Supervise + TUI** — `TOOL_EGRESS_TOKEN_ALLOW`; TUI suffix, modify guard,
+   required approval reason.
+3. **Addon glue** — async `request`, safe-tokens set, proposal write + async
+   poll, allow/block decision; pass `safe_tokens` into the WebSocket path.
+4. **On-match policy** — `dlp.outbound_on_match` through manifest → render →
+   addon; `redact` surface scrub with fail-closed re-scan; policy dispatch in
+   the addon's outbound handler.
+5. **Tests + docs** — core/supervise/TUI/manifest/render unit tests; README
+   egress + supervisor notes.
+
+### Out of scope
+
+The deferrals enumerated under **Non-goals** — restart persistence, inbound /
+WebSocket-frame supervision, cross-encoding generalisation, replacing
+`dlp.outbound_detectors`, and making `redact` the default.
+
+## Proposed Design
+
+### New services / components
+
+A new proposal tool constant `egress-token-allow` (`TOOL_EGRESS_TOKEN_ALLOW`)
+is added to `supervise.TOOLS`, and the egress addon gains an in-memory
+safe-tokens set plus the policy-dispatch path that drives it.
+
+On an outbound block the addon dispatches on the resolved policy:
+
+- **Structural blocks always 403.** A `ScanResult` with no `matched` value
+  (CRLF injection) is a hard `403` regardless of policy — there is nothing to
+  redact or safelist.
+- **`redact`** runs `redact_tokens` over the body, non-`host` header values,
+  and path/query, then re-scans. If the re-scan is clean the (rewritten)
+  request is forwarded; if a block-severity match remains (e.g. in the
+  hostname, or a unicode-evasion token redaction can't reach) it fails closed
+  with a `403`.
+- **`block`** writes the `403` immediately.
+- **`supervise`** runs the queue-and-wait loop, falling back to `block` when
+  supervise isn't wired for the bottle.
+
+For `supervise`, the addon writes the proposal directly to
+`SUPERVISE_QUEUE_DIR` (the queue is bind-mounted into the sidecar bundle and
+shared by every daemon, exactly as git-gate's `gitleaks-allow` proposal in PRD
+0061 does). The proposal's `proposed_file` is a human-readable text payload
+built by `build_token_allow_payload`:
+
+```
+egress blocked an outbound request carrying a detected token
+host: api.example.com
+method: POST
+path: /v1/ingest
+detector: OpenAI API key found in body
+context: ...before ******** after...
+```
+
+The justification tells the operator to approve only if the value is a false
+positive or a credential the request legitimately needs. The addon then polls
+`<proposal-id>.response.json` for `EGRESS_TOKEN_ALLOW_TIMEOUT_SECONDS` (default
+300). `approved`/`modified` allow the request and add the value to the
+safe-tokens set; `rejected`, malformed responses, and timeout fail the request
+closed. The proposal + response are archived to `processed/` after a decision.
+Because the wait happens inside mitmproxy's asyncio loop, the addon's `request`
+hook is async and polls with `asyncio.sleep`, so concurrent flows are
+unaffected.
+
+### Existing code touched
+
+- **Policy threading.** `dlp.outbound_on_match` is a per-route enum threaded
+  from the bottle manifest (`manifest_egress`) through the resolved route
+  (`egress.EgressRoute`), the rendered `routes.yaml` (`egress_render_routes`),
+  and the addon's `Route` (`egress_addon_core`). Unset renders nothing and
+  resolves to `supervise` at request time. The `list-egress-routes`
+  introspection endpoint round-trips it so the agent's proposals preserve it.
+- **Provider-route default.** Agent-provider routes (the agent talking to its
+  own LLM API — `api.anthropic.com`, the Codex backend, etc.) are the worst
+  source of token-shaped false positives because the whole conversation payload
+  flows through them. `egress_routes_for_bottle` fills `outbound_on_match=redact`
+  on any provider route that doesn't set it explicitly; a provider that sets the
+  policy keeps its choice, and manifest routes are unaffected (they default to
+  `supervise`).
+- **Scanners.** `scan_outbound` (and the token detectors `scan_token_patterns`
+  / `scan_known_secrets` it calls) accept a `safe_tokens` set. A match whose
+  value is in `safe_tokens` is skipped, so an approved token no longer blocks;
+  the scanners keep searching past a safelisted match so a second, un-approved
+  secret in the same request is still caught. The WebSocket path is passed the
+  same `safe_tokens` set.
+- **Supervisor UI.** `cli/supervise.py` renders `egress-token-allow` like
+  `gitleaks-allow`: the text payload is shown, modify is unavailable (there is
+  no file patch to edit), and approval prompts for a non-empty reason recorded
+  in the response notes. There is no on-disk config diff, so — like
+  `gitleaks-allow` and `capability-block` — it writes no egress audit-log entry.
+- **Failure handling.** If `SUPERVISE_QUEUE_DIR` / `SUPERVISE_BOTTLE_SLUG` are
+  unset (supervise disabled for the bottle), the addon skips the queue and
+  returns the existing `403`. Any error writing the proposal or reading the
+  response also fails closed.
+
+### Data model changes
+
+- New per-route manifest field `dlp.outbound_on_match: block | redact |
+  supervise`, rendered into `routes.yaml` (omitted when unset).
+- `ScanResult` gains a `matched: str = ""` field carrying the raw substring the
+  detector matched. The token detectors populate it; the structural CRLF
+  detector leaves it empty. The value stays inside the egress sidecar process —
+  never written to a log line (logs use the redacted `context`) nor to the
+  proposal file.
+- Proposal text payload (above) plus `<proposal-id>.response.json` in
+  `SUPERVISE_QUEUE_DIR`, archived to `processed/` after a decision.
+- New env var `EGRESS_TOKEN_ALLOW_TIMEOUT_SECONDS` (default 300).
+
+### External dependencies
+
+None. Reuses the existing supervisor queue (`SUPERVISE_QUEUE_DIR`) and the
+mitmproxy addon framework already in the egress sidecar.
+
+## Open questions
+
+- Should `known_secrets` (provisioned `EGRESS_TOKEN_*` exfiltration) be
+  override-able at all, or only `token_patterns`? This PRD allows both —
+  approval is an explicit operator decision and the safe-tokens set matches the
+  exact found value — but a future revision could restrict `known_secrets` to
+  reject-only.

+# PRD 0063: Strengthen outbound exfiltration detection
+
+- **Status:** Active
+- **Author:** claude
+- **Created:** 2026-06-25
+- **Issue:** #259
+
+## Summary
+
+The current DLP system has two detection tiers: weak (vendor token regexes)
+and strong (exact matching of provisioned `EGRESS_TOKEN_*` values in multiple
+encodings). This PRD adds four complementary hardening layers in ranked order
+of impact:
+
+1. **Canary tokens** — inject a per-session fake secret into the agent's
+   environment; any outbound appearance is a zero-false-positive exfil signal.
+2. **Broadened known-value scanning** — extend the strong tier beyond
+   `EGRESS_TOKEN_*` via a `BOT_BOTTLE_SENSITIVE_PREFIXES` sidecar env var.
+3. **Fragmentation-resistant matching** — catch separator injection and
+   long-substring leaks via alnum projection and sliding-window substring
+   search.
+4. **Entropy scoring** — warn-only flag on high-entropy blobs as a
+   complementary signal for encrypted exfil.
+
+## Problem
+
+After PRD 0056 the outbound scan covers all HTTP request surfaces (host, path,
+query, headers, body). But the content-based strong tier only matches
+`EGRESS_TOKEN_*` values and their encodings. Three gaps remain:
+
+| Gap | How an agent exploits it |
+|-----|--------------------------|
+| No canary | There is no "can't be false-positive" signal |
+| Narrow prefix filter | Sensitive values provisioned under other env prefixes (MCP keys, API keys injected via the agent provider) are invisible to `scan_known_secrets` |
+| Fragmentation blindness | Inserting `-`, space, or `\n` between secret characters turns an exact-match into a miss |
+
+## Goals / Success Criteria
+
+1. Each launched bottle has a unique canary token in the agent's environment
+   under a randomized `WORD_WORD_SECRET` env var name. The egress sidecar gets
+   the same env var and registers that exact name through
+   `BOT_BOTTLE_SENSITIVE_PREFIXES`. Any outbound appearance of the canary
+   blocks the request as a known-secret match.
+2. `scan_known_secrets` accepts a `sensitive_prefixes` parameter (default:
+   `("EGRESS_TOKEN_",)`). `scan_outbound` reads
+   `BOT_BOTTLE_SENSITIVE_PREFIXES` from `environ` and merges those prefixes
+   in, so operators can mark additional env vars as scanned values without
+   changing the manifest schema.
+3. For every secret that passes exact-match, a secondary alnum-projection pass
+   checks for the secret with all non-alphanumeric characters stripped. This
+   catches separator-injection evasion (`MY-SECRET` → body contains
+   `MY SECRET`).
+4. A sliding-window partial-match pass checks for long-enough contiguous
+   substrings of the secret's alnum projection in the text's alnum projection.
+   Any match ≥ `PARTIAL_MATCH_MIN_LEN` (12 chars) blocks with reason
+   `"partial match"`.
+5. A new `scan_entropy` detector flags outbound text windows with Shannon
+   entropy ≥ `ENTROPY_BLOCK_THRESHOLD` (5.5 bits/char) at **warn** severity
+   only. It is registered under the new detector name `"entropy"` in
+   `OUTBOUND_DETECTOR_NAMES` and disabled by default (routes must opt in).
+6. Binary request bodies are decoded via `latin-1` instead of
+   `utf-8 errors="replace"`, preserving every byte value and allowing
+   ASCII-range secrets to be found within binary payloads.
+7. All new behaviour is unit-tested; existing tests pass unchanged.
+
+## Non-goals
+
+- Rolling per-host buffer for split-across-requests detection (state in the
+  stateless addon is complex; deferred).
+- Additional vendor regexes.
+- ML / embedding-based detection.
+- Entropy-based hard blocks (warn only per the issue).
+
+## Design
+
+### Canary token flow
+
+```
+Egress.prepare()
+  canary = secrets.token_urlsafe(32)
+  canary_env = <random WORD_WORD_SECRET>
+  EgressPlan(canary=canary, canary_env=canary_env, ...)
+
+Docker compose render:
+  sidecar env: <canary_env>=<canary>
+  sidecar env: BOT_BOTTLE_SENSITIVE_PREFIXES=<canary_env>
+  agent env:   <canary_env>=<canary>      ← visible to agent as a "secret"
+
+macos-container launch: same literals added to sidecar + agent env entries
+```
+
+The sidecar uses `BOT_BOTTLE_SENSITIVE_PREFIXES` to make the random canary env
+name part of the existing `scan_known_secrets` detector without adding a
+manifest schema field.
+
+### Broadened known-value scanning
+
+`scan_known_secrets` gains a `sensitive_prefixes` parameter:
+
+```python
+def scan_known_secrets(
+    text: str,
+    *,
+    location: str = "body",
+    env: Mapping[str, str] | None = None,
+    sensitive_prefixes: tuple[str, ...] = ("EGRESS_TOKEN_",),
+) -> ScanResult | None:
+```
+
+`scan_outbound` reads `BOT_BOTTLE_SENSITIVE_PREFIXES` (comma-separated list
+of additional prefixes) from `environ` and appends them:
+
+```python
+extra = tuple(
+    p for p in environ.get("BOT_BOTTLE_SENSITIVE_PREFIXES", "").split(",") if p
+)
+sensitive_prefixes = ("EGRESS_TOKEN_",) + extra
+```
+
+`redact_tokens` receives the same treatment for consistent redaction.
+
+### Fragmentation-resistant matching
+
+A new helper `_alnum_projection(text)` strips all non-alphanumeric characters.
+`scan_known_secrets` runs two passes per secret:
+
+1. **Exact pass** — existing encoded-variant loop (unchanged).
+2. **Alnum-projection pass** — if the secret's alnum projection has ≥ 8 chars,
+   check if it appears in the text's alnum projection. Match → block with
+   `"fragmented match (separator injection)"` reason.
+3. **Partial-substring pass** — if the secret's alnum projection has ≥
+   `PARTIAL_MATCH_MIN_LEN` chars (12), slide a window of that length across the
+   secret's projection and look for each window in the text's alnum projection.
+   First match → block with `"partial match"` reason.
+
+All three passes run only for the `"known_secrets"` detector; the token-pattern
+and entropy detectors are unchanged.
+
+### Entropy scoring
+
+New public function:
+
+```python
+def scan_entropy(
+    text: str,
+    *,
+    location: str = "body",
+    window: int = ENTROPY_WINDOW,           # 64
+    threshold: float = ENTROPY_BLOCK_THRESHOLD,  # 5.5
+) -> ScanResult | None:
+```
+
+Slides a window of `window` characters across `text` in steps of `window // 2`.
+If any window's Shannon entropy exceeds `threshold`, returns a **warn**-severity
+`ScanResult`. Never blocks.
+
+`OUTBOUND_DETECTOR_NAMES` gains `"entropy"`. Routes opt in via their `dlp`
+block; entropy scanning is **off by default** to avoid false-positive noise on
+legitimate binary payloads.
+
+### Binary body handling
+
+In `scan_outbound`, the bytes → str decoding changes from:
+
+```python
+body.decode("utf-8", errors="replace")
+```
+
+to:
+
+```python
+body.decode("utf-8") if body is str else body.decode("latin-1")
+```
+
+`latin-1` is a bijective byte↔codepoint mapping; every byte value is preserved
+as its corresponding Latin-1 code point, so ASCII-range secret strings remain
+intact and `str.find` / regex still locate them correctly. The fallback from
+strict UTF-8 is tried first so valid UTF-8 bodies are decoded faithfully.
+
+## Implementation
+
+Delivered in three commits on the same branch:
+
+1. **DLP detector changes** — `_alnum_projection`, fragmentation passes,
+   `scan_entropy`, broadened `scan_known_secrets`, updated `scan_outbound` and
+   `redact_tokens`; all accompanying unit tests.
+2. **Canary injection** — `EgressPlan.canary`, `Egress.prepare()`,
+   Docker compose + macos-container backend injection.
+3. **PRD flip** — `Status: Draft → Active`.

+- **Status:** Active
+- **Author:** claude
+- **Created:** 2026-06-25
+- **Issue:** #257
+
+## Summary
+
+The `LOG_FULL` egress logging path (`_log_request` and `_log_response` in `egress_addon.py`) writes request/response headers and bodies to stderr without redaction and includes the sidecar-injected upstream `Authorization` header verbatim. This PR applies `redact_tokens` to header values and bodies in both log functions and strips the injected `Authorization` header from request logs entirely.
+
+## Problem
+
+`LOG_FULL` (log level 2) is intended for debugging egress traffic. When active it calls `_log_request` and `_log_response`. Both functions have two related bugs:
+
+1. **Injected `Authorization` header exposure.** `_log_request` is called *after* the sidecar injects upstream credentials (`flow.request.headers["authorization"] = decision.inject_authorization`). The full header dict — including the live credential — is serialized to stderr. Any log collector that ingests the egress container's stderr will receive the upstream bearer token in plaintext.
+
+2. **Unredacted bodies and header values.** Neither `_log_request` nor `_log_response` passes body or header values through `redact_tokens`. By contrast, `_req_ctx` (used for block/warn events) already calls `redact_tokens` on path and host. Any provisioned secret or recognized token pattern that appears in a request body, response body, or non-Authorization header value will be logged verbatim under `LOG_FULL`.
+
+These two bugs compose: an agent that enables `LOG_FULL` and simultaneously triggers a request that carries a known token gains a write path from credentials → egress logs.
+
+## Goals / Success Criteria
+
+- `_log_request` never logs the `authorization` header in any form.
+- `_log_request` applies `redact_tokens(value, env=os.environ)` to every other header value before serializing.
+- `_log_request` applies `redact_tokens(body, env=os.environ)` to the request body before logging.
+- `_log_response` applies `redact_tokens(value, env=os.environ)` to every response header value before logging.
+- `_log_response` applies `redact_tokens(body, env=os.environ)` to the response body before logging.
+- Unit tests cover each of the five cases above.
+
+## Non-goals
+
+- Redacting host or path in the full-log path (already covered by `_req_ctx` for block/warn events; `_log_request` already calls `redact_tokens` on host and path).
+- Suppressing `LOG_FULL` or adding a new log level.
+- Changing the outbound DLP scan logic.
+
+## Design
+
+### `_log_request`
+
+```python
+def _log_request(self, flow: http.HTTPFlow) -> None:
+    headers = {
+        k: redact_tokens(v, env=os.environ)
+        for k, v in flow.request.headers.items()
+        if k.lower() != "authorization"
+    }
+    body = redact_tokens(flow.request.get_text(strict=False) or "", env=os.environ)
+    sys.stderr.write(
+        json.dumps({
+            "event": "egress_request",
+            "host": redact_tokens(flow.request.pretty_host, env=os.environ),
+            "method": flow.request.method,
+            "path": redact_tokens(flow.request.path, env=os.environ),
+            "headers": headers,
+            "body": body,
+        })
+        + "\n"
+    )
+```
+
+The `authorization` key is excluded because by the time `_log_request` is called the sidecar has already injected the upstream credential (`decision.inject_authorization`). Logging it would write a live bearer token to stderr on every allowed request. There is no safe subset to log — the value is always a live credential or empty.
+
+### `_log_response`
+
+```python
+def _log_response(self, flow: http.HTTPFlow) -> None:
+    headers = {
+        k: redact_tokens(v, env=os.environ)
+        for k, v in flow.response.headers.items()
+    }
+    body = redact_tokens(flow.response.get_text(strict=False) or "", env=os.environ)
+    sys.stderr.write(
+        json.dumps({
+            "event": "egress_response",
+            "host": flow.request.pretty_host,
+            "status": flow.response.status_code,
+            "headers": headers,
+            "body": body,
+        })
+        + "\n"
+    )
+```
+
+Response headers don't carry injected credentials, so no header name is suppressed — only the values are scrubbed by `redact_tokens`.

+# PRD 0065: Multi-parent `extends:` for bottles
+
+- **Status:** Active
+- **Author:** didericis
+- **Created:** 2026-06-25
+- **Issue:** #268
+- **Extends:** PRD 0025 (`0025-bottle-extends.md`)
+
+## Summary
+
+Allow a bottle's `extends:` field to accept either a single bottle name (existing
+behavior) or a list of bottle names (new). Multiple parents are resolved
+independently and folded left-to-right into a single effective parent before the
+child is merged on top. This lets orthogonal concerns (base env, networking/egress,
+agent provider) live in separate bottles and be composed without forcing them into a
+linear chain.
+
+## Problem
+
+PRD 0025 shipped single-parent `extends:` and listed "No multi-parent inheritance"
+as a non-goal. In practice, users want to compose multiple orthogonal bottles — a
+base environment, a networking profile, and an agent-provider override — without
+creating a three-level linear chain that couples unrelated parents to each other.
+The linear chain workaround has two problems:
+
+1. **Ordering constraint.** `networking extends base` works, but then
+   `agent extends networking` can't also pick up `base` without going through
+   `networking`, coupling two unrelated concerns.
+
+2. **Quadratic duplication.** N orthogonal bottles require O(N²) chain variants
+   (one chain per permutation of applied concerns).
+
+Multi-parent `extends:` removes both constraints: each orthogonal concern stays in
+its own bottle, and the child bottle is the only place that names the combination.
+
+## Goals / Success Criteria
+
+- `extends:` accepts a list of strings in addition to a plain string.
+- Backward compat: existing single-string `extends:` is unchanged.
+- Parents are resolved left-to-right; later entries win on conflict.
+- Child wins over all parents (unchanged from PRD 0025).
+- Cycle detection covers multi-parent graphs, not just linear chains.
+- Diamond inheritance: a shared ancestor is resolved once (via the existing cache).
+- Invalid list entries (non-string, undefined bottle, self-reference) die at parse
+  with clear messages.
+- `manifest_loader.py`'s `load_bottle_chain_from_dir` enqueues all parents from a
+  list `extends:` so the resolver sees every bottle in the graph.
+
+## Non-goals
+
+- No change to the agent-vs-bottle trust boundary (PRD 0025 "Alternatives
+  considered" option 2 stays rejected).
+- No MRO / C3 linearization. Left-to-right fold is sufficient for the expected use
+  cases.
+- No preflight display of per-field provenance across multiple parents (same open
+  question as PRD 0025; remains a follow-up).
+
+## Design
+
+### Schema
+
+`extends:` now accepts either form:
+
+```yaml
+# single parent (unchanged)
+extends: base
+
+# multiple parents (new)
+extends: [base, networking]
+```
+
+Both forms are normalized to a list internally. A list with one element behaves
+identically to the string form.
+
+### Merge rules for multi-parent fold
+
+Parents are folded pairwise left-to-right before the child merge. For each step in
+the fold, the "earlier" bottle is the running accumulator and the "later" bottle is
+the next parent. Rules per field:
+
+| Field              | Fold rule                                                    |
+|--------------------|--------------------------------------------------------------|
+| `env`              | dict merge; later wins on key collision                      |
+| `git-gate.user`    | per-field overlay; later's non-empty fields win              |
+| `git-gate.repos`   | union by name; for same-name entries, later wins per-field   |
+| `egress.routes`    | concatenate (earlier first, later appended)                  |
+| `egress.log`       | later wins (last-wins)                                       |
+| `agent_provider`   | later wins (last-wins)                                       |
+| `supervise`        | later wins (last-wins)                                       |
+
+After the fold, the combined parent is merged against the child using the existing
+PRD 0025 rules (child always wins). The child's `egress.routes` appends to the
+combined parent's concatenated routes; `validate_egress_routes` runs once on the
+final merged set and catches duplicate hosts.
+
+### Algorithm
+
+```
+extends: [p1, p2, p3]
+
+fold:
+  combined = resolve(p1)
+  combined = fold_two(combined, resolve(p2))
+  combined = fold_two(combined, resolve(p3))
+
+merge:
+  result = _merge_bottles(combined, child_raw, name)
+```
+
+`fold_two(earlier, later)` applies the rules in the table above. Cycle detection
+(the `seen` tuple) is passed to each parent resolution call unchanged — if any
+parent's chain circles back to the current bottle, it is caught. The `cache` dict
+ensures a shared ancestor is only resolved once across all parents.
+
+### Error cases
+
+| Condition                              | Error message shape                                              |
+|----------------------------------------|------------------------------------------------------------------|
+| `extends` is not a string or list      | `extends must be a string or list of strings (was <type>)`       |
+| A list entry is not a string           | `extends[<i>] must be a string (was <type>)`                     |
+| A list entry names an undefined bottle | `extends '<name>' which is not defined. Available bottles: ...`  |
+| A list entry is the bottle itself      | `extends itself; remove the self-reference`                      |
+| Cycle through any parent edge          | `is in an extends cycle: <chain>`                                |
+
+## Implementation
+
+### `bot_bottle/manifest_extends.py`
+
+- `_resolve_one_bottle`: accept `str | list[str]` for `extends`; normalize to list;
+  validate each entry; for a single-entry list fall through to the existing
+  single-parent path; for multiple entries call `_fold_parents` then
+  `_merge_bottles`.
+- `_fold_parents(parent_names, raws, cache, repos_cache, seen)`: resolve each
+  parent and fold pairwise left-to-right; return `(effective_bottle,
+  effective_repos_raw)`.
+- `_fold_two_bottles(earlier, earlier_repos_raw, later, later_repos_raw)`: apply
+  the fold rules above; return `(folded_bottle, folded_repos_raw)`.
+
+### `bot_bottle/manifest_loader.py`
+
+- `load_bottle_chain_from_dir`: when `extends` is a list, enqueue all parent names
+  for loading (previously only `isinstance(parent, str)` was handled).
+
+### `tests/unit/test_manifest_extends.py`
+
+- `TestExtendsErrors.test_non_string_extends_dies`: update to use an integer
+  `extends` value (a list is now valid).
+- New class `TestExtendsMultiParent` covering all cases listed in the issue.
+
+## Testing strategy
+
+Unit tests via `ManifestIndex.from_json_obj` (same resolver surface used by all
+paths). No integration test changes needed — downstream code consumes the already-
+merged bottle and is unchanged.
+
+Test cases:
+- Two-parent list: env union, egress routes concat, git repos union
+- Last-parent-wins on scalar (supervise, agent_provider)
+- Child wins over all parents on conflict
+- Diamond: two parents share an ancestor; ancestor resolved once
+- Single-element list: identical to string form
+- Non-string extends value → ManifestError
+- Non-string list entry → ManifestError
+- Undefined bottle in list → ManifestError
+- Self-reference in list → ManifestError
+- Cycle through multi-parent edge → ManifestError

+# PRD 0066: Separate agent and bottle selection
+
+- **Status:** Active
+- **Author:** claude
+- **Created:** 2026-06-25
+- **Issue:** #269
+
+## Summary
+
+Agents and bottles are two separate concerns: agents carry a system prompt and
+skills; bottles carry infrastructure configuration (egress, git-gate, env,
+agent provider). Today an agent's manifest file hard-codes a single `bottle:`
+reference, which prevents the same agent prompt from being reused across
+projects that need different bottle configurations. This PRD decouples them: at
+launch time, after choosing the agent, the operator picks an ordered list of
+bottles via a multi-select picker. The selected bottles are merged in order
+(later entries override earlier ones) to produce the effective bottle for the
+session.
+
+## Problem
+
+The current `bottle: <name>` field on an agent manifest file binds the agent
+permanently to one bottle. To use the same system prompt with a different bottle
+(e.g. `claude-implementer` at home vs. at a client site that needs a different
+egress policy), the operator must duplicate the agent file and change the
+`bottle:` field. Duplicate agent files drift out of sync.
+
+## Goals / Success Criteria
+
+1. `bottle:` in an agent's frontmatter becomes optional. Existing manifests with
+   `bottle:` continue to work unchanged (backward compat).
+2. After selecting an agent (via the existing single-select picker), a new
+   multi-select bottle picker appears showing all available bottles.
+3. The multi-select picker pre-populates with the agent's `bottle:` value when
+   present.
+4. Confirming with one or more bottles selected uses those bottles, merged in
+   selection order, as the effective bottle for the session.
+5. Confirming with an empty selection falls back to the agent's `bottle:` field.
+   If neither is set, a ManifestError is raised pointing the operator at the fix.
+6. The ordered bottle list is stored in launch metadata so `./cli.py resume`
+   uses the same bottles.
+7. The preflight summary (`y/N` screen) shows the effective bottle name(s).
+8. The multi-select picker supports incremental filtering, Space/Enter to toggle
+   selection, an ordered "Selected: ..." summary line, Ctrl-D to confirm, and
+   Esc/q to cancel the whole start operation.
+9. Unit tests cover: multi-select widget (filter, toggle, confirm, cancel),
+   the `cmd_start` bottle-picker step, and the manifest `load_for_agent`
+   runtime-bottle-merge path.
+
+## Non-goals
+
+- Reordering the selection list from within the picker (order = insertion order;
+  drag-and-drop is out of scope).
+- Storing bottle selection history / MRU.
+- Changes to `./cli.py edit`, `./cli.py list`, or `./cli.py info`.
+- Removing the `bottle:` key from the agent schema (it stays, now optional).
+
+## Design
+
+### `bot_bottle/cli/tui.py` — `filter_multiselect`
+
+```python
+def filter_multiselect(
+    items: list[str],
+    *,
+    title: str = "",
+    initial: list[str] | None = None,
+    tty_path: str = "/dev/tty",
+) -> list[str] | None:
+    """Multi-select variant of filter_select.
+
+    Returns the ordered list of selected items, or None on cancel.
+    Press Space/Enter to toggle the item under the cursor.
+    Press Ctrl-D to confirm. Press Esc/q to cancel.
+    """
+```
+
+Layout:
+
+```
+Select bottles
+Filter: _

+> [*] claude
+  [ ] dev
+  [ ] codex
+─────────────────────────────────────────
+Selected (in order): claude
+─────────────────────────────────────────
+[↑↓/jk] move  [Space] toggle  [Ctrl-D] done  [Esc] cancel
+```
+
+`initial` pre-populates the ordered selection. `None` means no pre-selection.
+Items added are appended in insertion order; items removed leave the remaining
+order unchanged.
+
+### `bot_bottle/manifest_schema.py` — optional `bottle:`
+
+`bottle` moves from `AGENT_KEYS_REQUIRED` to `AGENT_KEYS_OPTIONAL`.
+
+### `bot_bottle/manifest_agent.py` — optional `bottle:`
+
+`ManifestAgent.bottle` changes from `str` (required) to `str = ""`.
+`from_dict` no longer requires the key to be present; the bottle-exists
+validation is skipped when the key is absent.
+
+### `bot_bottle/manifest_loader.py` — `scan_bottle_names`
+
+```python
+def scan_bottle_names(bottles_dir: Path) -> list[str]:
+    """Scan <bottles_dir>/*.md and return sorted bottle names."""
+```
+
+### `bot_bottle/manifest.py` — `ManifestIndex` changes
+
+**`all_bottle_names` property** — analogous to `all_agent_names`; scans
+`home_md / "bottles"` in lazy mode, returns `sorted(self.bottles.keys())` in
+eager mode.
+
+**`load_for_agent(agent_name, bottle_names: tuple[str, ...] = ())`** — new
+`bottle_names` parameter. When non-empty, the listed bottles are resolved and
+merged in order (index 0 is the base; each subsequent bottle is applied on top
+using the same field-merge rules as `extends:`). The result replaces the bottle
+that `agent.bottle` would have provided. When empty, falls back to `agent.bottle`.
+Raises ManifestError if neither `bottle_names` nor `agent.bottle` is set.
+
+### `bot_bottle/manifest_extends.py` — `merge_bottles_runtime`
+
+```python
+def merge_bottles_runtime(bottles: list[ManifestBottle]) -> ManifestBottle:
+    """Merge an ordered list of pre-resolved ManifestBottle objects.
+
+    Index 0 is the base; each subsequent entry overrides the previous using
+    the same rules as the file-based extends machinery:
+      - env: dict merge, later wins
+      - git_user: per-field overlay, later wins on non-empty
+      - git (repos): union by name, later wins per-name
+      - egress.routes: concatenate
+      - agent_provider, supervise: later bottle's value replaces earlier
+    """
+```
+
+This function operates on already-parsed `ManifestBottle` objects, so it does
+not need to touch the raw-dict path.
+
+### `bot_bottle/backend/__init__.py` — `BottleSpec` + `_validate`
+
+`BottleSpec` gains `bottle_names: tuple[str, ...] = ()`.
+
+`BottleBackend._validate` passes `spec.bottle_names` to `load_for_agent`:
+
+```python
+manifest = spec.manifest.load_for_agent(spec.agent_name, spec.bottle_names)
+```
+
+The preflight print updates `info(f"bottle: {agent.bottle}")` to display the
+effective bottle name(s). When `spec.bottle_names` is non-empty those are
+shown; when empty and `agent.bottle` is set, the agent's `bottle:` is shown.
+
+### `bot_bottle/bottle_state.py` — persist bottle names
+
+`BottleMetadata` gains `bottle_names: tuple[str, ...] = ()`. `read_metadata`
+reads this from JSON (default `()`). `write_launch_metadata` passes
+`spec.bottle_names` through.
+
+### `bot_bottle/cli/start.py` — bottle multiselect step
+
+After agent selection, before the name/color modal:
+
+```python
+available_bottle_names = manifest.all_bottle_names
+# Peek at agent's bottle default for pre-population
+initial_bottle = _peek_agent_bottle(manifest, agent_name)
+initial = [initial_bottle] if initial_bottle else []
+
+bottle_names_list = tui.filter_multiselect(
+    available_bottle_names,
+    title="Select bottles",
+    initial=initial,
+)
+if bottle_names_list is None:
+    return 0  # user cancelled
+bottle_names = tuple(bottle_names_list)
+```
+
+`_peek_agent_bottle` reads the agent file's frontmatter without full parsing,
+returning the `bottle:` value or `""` when absent.
+
+`BottleSpec` is built with `bottle_names=bottle_names`.
+
+### `bot_bottle/cli/resume.py` — bottle names from metadata
+
+```python
+spec = BottleSpec(
+    ...
+    bottle_names=tuple(metadata.bottle_names),
+)
+```
+
