fix(macos-container): anchor relative Dockerfile path to build context

`container build` resolves -f relative to the current working directory,
not the build context, so builds failed from any cwd other than the repo
root. Anchor a relative Dockerfile to the context before passing it.

+  short-description: Score code quality with a strict rubric
+---
+
+# Quality Eval
+
+## Role
+
+Act as a Staff Software Engineer and automated quality gate. Evaluate code objectively against the rubric below, surface hidden anti-patterns, and provide a mathematical grade with atomic refactoring steps.
+
+## Evaluation Rules
+
+- Evaluate only against the five rubric dimensions.
+- Be candid. Do not inflate scores for politeness.
+- Avoid generic advice. Every recommendation must name a specific code location, behavior, or pattern and include a concrete improvement direction.
+- Inspect the code before scoring. For codebases, read enough representative files, tests, and architecture boundaries to justify the scope.
+- When exact line numbers are available, cite them.
+- Do not reveal private chain-of-thought. In the required `Chain of Thought Analysis` section, provide a concise, step-by-step audit rationale with observable findings and score justifications.
+
+## Rubric
+
+Score each dimension from 1 to 5 using these anchors:
+
+| Dimension | Score 1 (Fail) | Score 3 (Pass) | Score 5 (Exemplary) |
+| :--- | :--- | :--- | :--- |
+| **Architecture** | Spaghettified; tight coupling; violated separation of concerns. | Modular but relies on leaky abstractions or mixed domains. | Strict domain isolation; follows SOLID; clear dependency inversion. |
+| **Readability** | Cryptic naming; deep nesting (>3 levels); widespread DRY violations. | Idiomatic but features over-complex functions or sparse documentation. | Self-documenting; expressive naming; high cohesion; flat structure. |
+| **Resilience** | Swallows errors blindly; lacks contextual logging; fragile to bad input. | Basic try/catch blocks present but lacks granular, typed error handling. | Explicit error boundaries; contextual logging; structured failure modes. |
+| **Testability** | Hardcoded dependencies make mocking or isolated testing impossible. | Pure functions are testable, but side-effect heavy logic lacks test hooks. | Decoupled IO; deterministic execution; structured for unit and integration tests. |
+| **SecOps** | Hardcoded secrets; O(n^2) bottlenecks; zero input sanitization. | Safe from obvious flaws but lacks deep defensive optimization. | Validated inputs; optimized algorithmic complexity; zero security debt. |
+
+## Scoring Method
+
+1. Determine the evaluated scope and primary language.
+2. Identify concrete evidence for each dimension.
+3. Assign integer dimension scores from 1 to 5.
+4. Compute `composite_score` as the arithmetic mean of the five dimension scores, rounded to one decimal place.
+5. Include code snippets only when they make a refactoring step more actionable.
+
+## Required Output
+
+Structure every response into exactly these three Markdown sections:
+
+### 1. Chain of Thought Analysis
+
+Provide a concise step-by-step audit rationale. Name specific files, functions, patterns, anti-patterns, and rubric anchors. Keep it evidence-based and do not include hidden private reasoning.
+
+### 2. Normalized Score Report
+
+```json
+{
+  "evaluation_metadata": {
+    "target_scope": "string",
+    "primary_language": "string"
+  },
+  "metrics": {
+    "architecture_and_modularity": 0,
+    "readability_and_maintainability": 0,
+    "error_handling_and_resilience": 0,
+    "testability_and_mocking": 0,
+    "security_and_performance": 0
+  },
+  "composite_score": 0.0
+}
+```
+
+### 3. Atomic Refactoring Playbook
+
+* **High Priority (To lift Score 1/2 to 3):**
+  - [ ] Actionable, specific refactoring step with file/line/context reference.
+* **Medium Priority (To lift Score 3 to 4/5):**
+  - [ ] Optimization or architectural pattern implementation step.

+bot-bottle spins up an isolated backend runtime for running AI coding agents
+with a curated set of skills and env vars. The point is to run agents with
+broad permissions inside a sandbox, so a misbehaving agent cannot reach the
+host. A Python CLI (entry point `cli.py`, package `bot_bottle/`) orchestrates
+the runtime lifecycle and the copying of skills and env vars into it.
+The default backend on compatible macOS hosts is macos-container:
+agents and sidecar bundles run through Apple's `container` CLI without
+requiring Docker. The smolmachines backend remains available with
+`BOT_BOTTLE_BACKEND=smolmachines` or `--backend=smolmachines`; agents
+run in a libkrun micro-VM, while the sidecar bundle still uses Docker.
+The legacy Docker backend remains available with `BOT_BOTTLE_BACKEND=docker`
+or `--backend=docker`.

 - Low dependencies by default. The project is Python, stdlib-first (no

-Run multiple Claude Code agents on your own machine, each scoped to its own secrets, skills, and egress allowlist.
+**Problem:** Developer wants to run a coding agent without supervision, but they don't want a prompt injected or misbehaving agent wrecking their environment or exfiltrating sensitive data.
 
-![pipelock and git-gate blocking exfil attempts against a live bottle](docs/demo.gif)
+**Solution:** Ephemeral, per agent "bottles" the agent cannot modify that scan all traffic for data exfiltration and limit capabilities and egress to only what the agent needs.
 
-Four prompts to the agent inside a real bottle:
-claude replies to `hello there` — proof api.anthropic.com routes
-through pipelock's bumped TLS end-to-end;
-asked to GET a non-allowlisted host, the agent's curl gets 403 back
-from pipelock;
-asked to POST a credential-shaped body to an allowlisted host, the
-same 403 — pipelock's DLP body scanner caught it;
-asked to commit and push an AKIA-shaped key, git-gate's gitleaks
-pre-receive hook rejects the ref.
-Run it yourself with `bash scripts/demo.sh`.
+## Features
 
-## Why "bot-bottle"?
-
-Each container is a bottle; Claude is the genie inside. The genie's
-powers are exactly what the manifest grants it — a specific set of
-skills, a specific set of secrets, and a specific set of hosts it can
-reach — nothing more. You uncork one bottle per agent
-(`./cli.py start <agent>`), many bottles run in parallel, and each is
-scoped to its task. When the session ends the bottle is destroyed and
-the genie does not persist.
-
-## Goals
-
-- Scope each agent to the minimum credentials and network egress its task actually needs
-- Run multiple agents in parallel, isolated from each other
-- Keep code, credentials, and agent activity on infrastructure I control — no third-party agent runtime
-
-## Project status
-
-bot-bottle is a self-hosted secure runtime for AI coding agents.
-Each agent runs in an isolated container or micro-VM-backed bottle with
-scoped secrets, allowlisted egress, TLS-aware proxying, DLP checks, and
-a git-gate that withholds upstream credentials and scans pushes before
-forwarding. The project includes a documented threat model, PRD-driven
-development history, Docker and smolmachines backends, dashboard and
-remediation flows, and unit/integration tests covering exfiltration and
-sandbox escape scenarios.
-
-## Security model
-
-Each agent runs in its own bottle: its own container, its own internal
-Docker network, and its own pipelock sidecar. Bottles don't share
-state, don't talk to each other, and only get the env vars, skills,
-SSH identities, and egress hosts the manifest grants them — nothing
-more. Any one agent only has the access it needs to do its job.
-
-The bottle limits both what an agent can see and where it can send
-it. Each bottle gets only the secrets and SSH identities the manifest
-grants it — a Gitea token but not a GitHub token, a deploy key but
-not a personal SSH key — so even a compromised or misbehaving agent
-only handles credentials it was already trusted with for its job.
-Egress flows through pipelock, which constrains where those
-credentials can travel: an agent with a Gitea token can reach
-`gitea.dideric.is`, not arbitrary attacker-controlled hosts. The same
-constraint blocks DNS-over-HTTPS as an exfil channel — a DoH resolver
-like `cloudflare-dns.com` would have to be on the allowlist for the
-agent to reach it at all. The container itself adds a layer between
-the agent and the host, but the v1 design leans more on secret
-minimization and egress allowlisting than on the container as a
-hardened boundary. On Linux hosts where [gVisor](https://gvisor.dev/)
-is registered with Docker, bot-bottle auto-detects it and launches
-every bottle under `runsc` for a userspace syscall barrier — no
-manifest configuration required. The broader v2 discussion lives in
-`docs/research/stronger-isolation-alternatives.md`.
-
-The egress proxy and OAuth-token handling below are the load-bearing
-pieces of v1.
+- **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 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.
+- **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 pipelock + egress + git-gate +
-supervise behind a Python init supervisor (PRD 0024). They share a
-per-agent Docker `--internal` network; the agent has no default
-route off-box. All HTTP and HTTPS egress funnels through pipelock,
-where the egress allowlist, TLS interception, and request-body DLP
-scanner enforce the manifest before any byte leaves the host. The
-only egress that doesn't traverse pipelock is git-gate's SSH
-push/fetch to `bottle.git` upstreams — pipelock can't proxy SSH,
-so git-gate is its own L4-style egress path with gitleaks doing
-the pre-receive scan.
+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.
 
-The agent dials the bundle by the legacy short names (`pipelock`,
-`egress`, `git-gate`, `supervise`); the renderer registers those as
-docker-network aliases on the bundle so existing HTTPS_PROXY URLs
-and MCP endpoints resolve without an agent-side change.
+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:

-- **agent image** — built from the provider template Dockerfile
-  (`Dockerfile.claude` for Claude, `Dockerfile.codex` for Codex, or
-  `agent_provider.dockerfile`) on first run; runs the selected agent
-  CLI with the manifest-granted skills, env vars, and `~/.gitconfig`
-  (the latter for the git-gate's `insteadOf` rules when `bottle.git`
-  is set).
-- **pipelock image** — per-agent sidecar. Terminates the agent's
-  outbound HTTP/HTTPS, enforces the resolved allowlist, runs DLP
-  scanning. Design in `docs/prds/0001-per-agent-egress-proxy-via-pipelock.md`
-  and `docs/prds/0006-pipelock-tls-interception.md`.
-- **git-gate image** — per-agent sidecar built on `zricethezav/gitleaks`
-  (alpine + gitleaks + git-daemon + openssh-client). Runs
-  `git daemon` over `git://` as a bidirectional mirror of each
-  declared upstream. A pre-receive hook gitleaks-scans incoming
-  refs and forwards clean refs to the real upstream over SSH; an
-  access-hook runs `git fetch origin --prune` against the upstream
-  before every upload-pack so an agent fetch returns whatever the
-  upstream has *now* (fail-closed if unreachable). The agent's
-  `~/.gitconfig` rewrites the real URL to the gate via `insteadOf`,
-  so push, fetch, clone, and pull all route through. The agent
-  never sees the upstream credential. If the upstream's hostname
-  isn't resolvable from the gate container (e.g. a Tailscale-only
-  host whose public DNS points elsewhere), pin its IP via
-  `ExtraHosts: { "<hostname>": "<ip>" }` on the `bottle.git` entry —
-  the gate's `/etc/hosts` gets the override while the agent's
-  `insteadOf` rewrite still keys off the original hostname. Brought
-  up only when `bottle.git` has entries. Design in
-  `docs/prds/0008-git-gate.md`.
-- **cred-proxy image** — per-bottle sidecar (`python:3.13-alpine`
-  base, stdlib-only) that holds API tokens declared in
-  `bottle.cred_proxy.routes`. Each route names a `path`,
-  `upstream`, `auth_scheme`, and `token_ref` (host env var); the
-  agent dials `http://cred-proxy:9099<path>...` over plain HTTP
-  and the proxy strips any inbound `Authorization`, injects
-  `<auth_scheme> <token>` using the value held only in its own
-  container's environ, and forwards to the real upstream over
-  HTTPS. SSE responses stream back unbuffered. The cred-proxy's
-  outbound HTTPS routes through pipelock (it trusts pipelock's
-  per-bottle CA), so pipelock's egress allowlist + body scanner
-  apply to cred-proxy traffic the same way they apply to direct
-  agent traffic. Smart-HTTP push paths (`/git-receive-pack`,
-  `/info/refs?service=git-receive-pack`) are refused at the
-  proxy — push must go through `bottle.git` / git-gate where
-  gitleaks runs. Optional per-route `role` tags drive agent-side
-  rewrites: `anthropic-base-url`, `npm-registry`, `git-insteadof`,
-  `tea-login`. The agent's `printenv` shows only proxy URLs —
-  none of the real token values. Design in
-  `docs/prds/0010-cred-proxy.md`.

+When the agent exits, `cli.py` tears down every sidecar and both networks; nothing about a bottle persists between runs.
 
 ## Quickstart
 
-Requires Docker on the host and a long-lived Claude Code OAuth token in
-your shell env.
+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`.
+
+Use `BOT_BOTTLE_BACKEND=docker ./cli.py start <agent>` on hosts where Apple Container is not installed and Docker is the desired backend.
 
 ```sh
 ./cli.py start <agent>   # builds the image on first run, drops you into claude
 ```
 
-The container is removed automatically when the session ends. If the script
-is killed with SIGKILL the exit trap won't fire and the container may be
-left running; remove it with `docker rm -f <container-name>`.
-
-### Smolmachines backend (experimental, macOS-only)
-
-A second backend runs the agent in a smolvm micro-VM (libkrun) with the
-sidecar bundle still in Docker. Selected via
-`BOT_BOTTLE_BACKEND=smolmachines ./cli.py start <agent>`. Requires
-`smolvm` on PATH (`curl -sSL https://smolmachines.com/install.sh | sh`).
-
-The integration tests run against whichever backend the env var
-selects and skip cleanly when its prerequisites are missing.
-
-**One-time sudo on first launch (macOS):** smolmachines bottles
-each reserve a loopback alias from a pool (`127.0.0.16` ..
-`127.0.0.31`) and bind their bundle's port-forwards to it; the
-first `./cli.py start` after each reboot prompts for sudo to add
-missing aliases via `ifconfig lo0 alias`. Aliases persist until
-reboot; subsequent launches don't prompt. The agent's TSI
-allowlist is the alias's `/32`, so each bottle can only reach
-its own bundle's published ports — not other bottles' ports,
-not other host loopback services (postgres, dev servers, etc.).
-
-This enforcement requires a workaround for a smolvm 0.8.0 bug:
-the CLI's `--allow-cidr` flag is silently dropped when combined
-with `--from <smolmachine>`. The launcher patches smolvm's
-persistent state DB
-(`~/Library/Application Support/smolvm/server/smolvm.db`)
-directly between `machine create` and `machine start` to set
-the allowlist. The hack falls away automatically when smolvm
-honors the flag upstream — see the `loopback_alias` module's
-docstring for the investigation trail.
-
 ## Manifest
 
-Bottles and agents live as Markdown files with YAML frontmatter under
-`~/.bot-bottle/`. Each bottle is one file in `bottles/`, each agent
-is one file in `agents/`:
+Bottles and agents are Markdown files with YAML frontmatter under `~/.bot-bottle/`. The Markdown body is the system prompt. Bottles live in `~/.bot-bottle/bottles/`; agents may also be shipped by a repo at `<repo>/.bot-bottle/agents/<name>.md`.
 
-```
-~/.bot-bottle/
-├── bottles/
-│   ├── dev.md
-│   └── gitea-dev.md
-└── agents/
-    ├── implementer.md
-    └── researcher.md
-```
-
-The filename (without `.md`) is the entity's name. Filenames must
-match `[a-z][a-z0-9-]*`; files that don't are skipped with a warning.
-
-A repo can ship its own agent files alongside its code at
-`<repo>/.bot-bottle/agents/<name>.md`. Those agents reference
-bottles defined in `~/.bot-bottle/bottles/` (the only place
-bottles can come from); a `bottles/` subdir in a repo is ignored
-with a warning. **This is the trust boundary**: bottle infrastructure
-— credentials, egress allowlists, git remotes — comes from your home
-directory only. A cloned repo cannot redirect a host env var to an
-attacker-named upstream because it has no way to declare a bottle.
-
-### Bottle composition with `extends:`
-
-A bottle can inherit from another via `extends: <bottle-name>` so
-operators don't have to duplicate a whole bottle file to vary one
-field (PRD 0025). The parent's resolved config is the base; the
-child's declared fields overlay. Merge rules:
-
-- `env:` — dict merge, child wins on key collision.
-- `git.user:` — per-field overlay (child's non-empty `name` /
-  `email` wins; empty falls through to parent).
-- `git.remotes:` — dict merge by host, child wins on host collision.
-  An explicit `git.remotes: {}` clears the parent's remotes; omitting
-  `git.remotes` inherits the parent's remotes.
-- `agent_provider:`, `egress:`, `supervise:` — full replace when the
-  child declares the field.
-
-```yaml
----
-extends: dev          # inherit everything from bottles/dev.md
-egress:
-  routes:
-    - host: staging.example.com
-      auth:
-        scheme: Bearer
-        token_ref: STAGING_TOKEN
----
-```
-
-Cycles (`A extends B extends A`), self-references, and missing
-parents die at parse with a clear pointer. Bottles remain
-`$HOME`-only — `extends:` preserves the trust boundary above.
-
-### Provider base bottles
-
-Keep provider/runtime policy in one home-owned base bottle, then have
-task bottles extend it. That keeps provider egress/auth in one place
-without hiding security-relevant routes behind `agent_provider.template`.
-
-For example, `~/.bot-bottle/bottles/claude.md` can hold the Claude
-provider selection and Anthropic API egress:

-reject them, so the same file can drop into `~/.claude/agents/` as a

+**Egress route fields:**
 
-Unknown top-level frontmatter keys die at load with a "did you mean"
-pointer; typos don't silently ghost into an empty config.
+| Field | Required | Description |
+|---|---|---|
+| `host` | yes | Hostname to allowlist. One entry per host. |
+| `role` | no | Reserved for future use. The key is recognised but any value is currently rejected at load. Provider auth routes (e.g. Claude's `api.anthropic.com`) are injected automatically from `agent_provider.auth_token`, not via `role`. |
+| `auth.scheme` | when `auth` present | `Bearer` or `token`. Injected by the proxy; the agent never sees the value. |
+| `auth.token_ref` | when `auth` present | Env-var name holding the secret on the host. |
+| `matches` | no | Array of `{paths, methods, headers}` filters. A request must match at least one entry (if any are given) to be forwarded. |
+| `matches[].paths` | no | Array of `{type, value}`. `type` is `prefix` (default), `exact`, or `regex`. |
+| `matches[].methods` | no | Array of HTTP method strings, e.g. `[GET, POST]`. |
+| `matches[].headers` | no | Array of `{name, value, type}`. `type` is `exact` (default) or `regex`. |
+| `dlp` | no | Per-route DLP overrides. Omit to use defaults (all detectors on). |
+| `dlp.outbound_detectors` | no | `false` disables outbound scanning; list restricts to named detectors (`token_patterns`, `known_secrets`). |
+| `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. |
 
-The YAML subset the frontmatter accepts is bounded (flat keys,
-strings / ints / true-or-false bools / null / lists / one-level
-nested dicts). Anchors, multi-line block scalars, tags, and
-ambiguous bare strings (`yes` / `NO` / `2026-05-24` /
-`0x...`) all die with a clear pointer at the spec — quote your
-strings when in doubt. The full schema lives in
-`bot_bottle/yaml_subset.py` (~450 lines, stdlib-only, no PyYAML).
+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.

-## Auth: Claude OAuth token, not API key
-
-Bottles that use `agent_provider.template: claude` authenticate
-`claude` inside the container with the same Pro/Max subscription you
-already use on the host, via a long-lived OAuth token. No
-`ANTHROPIC_API_KEY` is needed.
-
-**Why a token instead of mounting `~/.claude.json`:** on macOS, Claude
-Code stores OAuth credentials in the encrypted Keychain, not in
-`~/.claude.json`. Mounting that file into a Linux container does not
-carry the credentials with it. Linux hosts keep credentials in
-`~/.claude/.credentials.json`, but to keep the launcher portable
-bot-bottle uses the env-var path on every host.
-
-**One-time setup on the host:**
-
-```sh
-claude setup-token   # browser login, prints a ~1-year OAuth token
-```
-
-Stash the token in your shell env (e.g. `~/.zshrc` or a secret manager)
-as `BOT_BOTTLE_CLAUDE_OAUTH_TOKEN`:
-
-```sh
-export BOT_BOTTLE_CLAUDE_OAUTH_TOKEN="<token>"
-```
-
-The Claude bottle reaches the Anthropic API only through the cred-proxy
-sidecar. To let `claude` authenticate, declare an egress route with
-`role: claude_code_oauth` and
-`token_ref: BOT_BOTTLE_CLAUDE_OAUTH_TOKEN`:
-
-```yaml
-egress:
-  routes:
-    - host: api.anthropic.com
-      role: claude_code_oauth
-      auth:
-        scheme: Bearer
-        token_ref: BOT_BOTTLE_CLAUDE_OAUTH_TOKEN
-      pipelock:
-        tls_passthrough: true
-```
-
-Routes that resolve to private or Tailscale addresses can opt into
-pipelock's SSRF destination allowlist explicitly:
-
-```yaml
-egress:
-  routes:
-    - host: gitea.dideric.is
-      auth:
-        scheme: token
-        token_ref: BOT_BOTTLE_GITEA_TOKEN
-      pipelock:
-        ssrf_ip_allowlist:
-          - 100.78.141.42/32
-```
-
-At launch, `cli.py` reads `BOT_BOTTLE_CLAUDE_OAUTH_TOKEN` from the host
-env and forwards it into the cred-proxy container's environ — never
-into the agent's. The agent receives `ANTHROPIC_BASE_URL` pointing at
-`http://cred-proxy:9099/anthropic` and a non-secret placeholder for
-`CLAUDE_CODE_OAUTH_TOKEN` (claude-code refuses to start without one;
-the proxy strips and replaces the header on every request). `printenv`
-inside the agent does not surface the real token, and the value is
-never written to disk or placed on argv on the host.
-
-A Claude bottle without a `claude_code_oauth` route has no path to the
-Anthropic API — there is no fallback that forwards the token directly
-to the agent. Caveats: the token is bound to your subscription tier
-(Pro/Max/Team/Enterprise), it does not work with `claude --bare`
-(which only reads `ANTHROPIC_API_KEY`), and if it leaks, regenerate
-via `claude setup-token` again. Reference:
-<https://code.claude.com/docs/en/authentication>.
+More examples in `examples/`. Full design lives under `docs/prds/`; the trust-boundary rationale is in `docs/prds/0011-per-file-md-manifest.md`.

+"""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):
