fix: retarget the demo at macos-container and re-record

The Docker backend cannot launch a bottle on this host: the
orchestrator publishes 127.0.0.1:8099 but is attached only to the
`--internal` control network, so Docker accepts the mapping and never
establishes the forward (PortBindings set, NetworkSettings.Ports
empty). Every launch dies on `orchestrator did not become healthy`.
That is independent of the demo and left alone here, because fixing it
means touching the L3 isolation the control network exists to provide.

Pin the tape to macos-container, which launches cleanly, and drop the
Docker daemon check and image pre-warm from setup. The pre-warm is not
replaced with a `container build` equivalent: build_image() applies
--dns handling that would become a second, drifting copy in shell, and
the warm layer cache already keeps rebuilds fast. Pre-warm never kept
BuildKit off camera anyway — the launcher prints CACHED lines
regardless, so that comment was wrong when it was written.

Launch via --headless. The interactive path opens four selectors in a
row and the tape drove none of them; it also lists every bottle in
~/.bot-bottle/bottles/, putting the operator's own bottle names in a
GIF that ships in the README. --headless is one-shot by construction
(`claude -p`), so all probes ride in on a single --prompt rather than
being typed as follow-ups into a session that has already exited.

Spell the probes as literal shell commands. Left in English, one take
had the agent substitute a placeholder for $FAKE_TOKEN: the DLP
scanner had nothing to match and gitleaks found nothing to flag, so
both controls reported a clean pass without ever being exercised.
Neither curl discards the body, so the recording shows the host-filter
refusal and the DLP refusal as visibly different reasons instead of
two identical 403s.

Drop the git/gitleaks probe. In the last run carrying it, gitleaks
reported `no leaks found` on an AKIA-shaped key and the gate forwarded
the push, which failed only because upstream.invalid does not resolve.
A recording of that reads as the gate catching a secret while showing
the opposite. Tracked in #541.

+# PRD 0081: Reprovision gateway-dependent state on gateway bring-up
+
+- **Status:** Active
+- **Author:** claude
+- **Created:** 2026-07-26
+- **Issue:** #516
+
+## Summary
+
+When the gateway is (re)built, reconcile every already-running bottle against the
+fresh gateway instead of persisting the gateway's state. On a gateway cold boot,
+the gateway reconciles all live bottles in one flow: **replace** each agent's
+trusted CA with the freshly-minted gateway CA, **re-provision** each bottle's
+git-gate repos + creds onto the gateway, and **restore** each bottle's egress
+tokens. One mechanism across all three services; the CA rotates for free on every
+bring-up.
+
+## Problem
+
+A gateway rebuild/restart silently breaks every already-running bottle:
+
+- **CA (#510).** The gateway's mitmproxy mints a new CA on a fresh rootfs; agents
+  still trust the old one, so egress fails TLS verification (`SSL certificate
+  verification failed`).
+- **git-gate (#512).** Per-bottle bare repos (`/git/<id>`) + deploy creds
+  (`/git-gate/creds/<id>`) live in the gateway's ephemeral rootfs; a rebuild wipes
+  them and the agent 404s on fetch/push.
+
+Both are the same root cause: per-bottle gateway-dependent state is provisioned
+**once, at bottle launch**, and nothing restores it for already-running bottles
+when the gateway comes back. The existing launch-time reprovision
+(`reprovision_bottles`) restores **only** egress tokens, and only as a side effect
+of the *next* launch.
+
+Persisting the state (a host bind-mount / a per-VM data volume per service) was
+prototyped and rejected: it differs per service (a volume for the CA, another for
+git-gate, reprovision for tokens), it pins the CA static forever (no rotation),
+and it adds volume surface that `docker volume prune` / a wiped cache can silently
+destroy (the original #450 failure mode).
+
+## Goals / Success Criteria
+
+- A gateway (re)boot restores **all** running bottles' gateway-dependent state
+  with no manual step and no relaunch — the agent's next egress / fetch / push
+  just works.
+- **One** reconcile flow covering CA, git-gate, and egress tokens, rather than a
+  different mechanism per service.
+- The CA **rotates** on every gateway bring-up (no long-lived CA), distributed to
+  running agents by the same reconcile.
+- Per-bottle failures are tolerated: one unreachable or malformed bottle does not
+  block the others or the gateway coming up.
+- **All backends** (Firecracker, docker, macOS) reconcile through the *same*
+  contract — an abstract method on the backend base class, so a new backend
+  cannot forget to implement it and none drifts onto a bespoke mechanism.
+
+## Non-goals
+
+- Deliberate mid-session CA rotation *without* a gateway restart — `rotate_ca`
+  stays for that operator action.
+- Changing source-IP attribution, `/resolve`, or the plane split (#469).
+
+## Design
+
+**The contract — `attach_bottled_agents_to_gateway()` on the backend ABC.**
+Reconciling running bottles against the current gateway is a backend
+responsibility (only the backend can enumerate its agents and reach them —
+firecracker over SSH, docker/macOS over `exec`/`cp`), so it is an
+`@abc.abstractmethod` on `BottleBackend` (`backend/base.py`). Every backend
+implements it; the host calls it whenever the gateway is (re)brought up. This is
+what makes the fix cross-backend by construction rather than a per-backend
+follow-up. It reprovisions **all** registered bottles' gateway-dependent state:
+CA, git-gate, and egress tokens.
+
+**Trigger — the gateway bring-up path.** The host calls
+`attach_bottled_agents_to_gateway()` only when the gateway was actually
+(re)brought up — the cold-boot branch of the infra bring-up (e.g.
+`FirecrackerInfraService.ensure_running` after it boots a fresh pair), never on an
+adopt of a healthy, current gateway (state intact). So it fires exactly when the
+gateway was (re)booted — including orchestrator restarts, since the pair boots
+together — and there is no bare-restart path that bypasses bring-up.
+
+**Per-backend implementation.** Each backend's `attach_bottled_agents_to_gateway`
+enumerates its live bottles and, for each, reconciles the three services against
+the current gateway. The firecracker implementation, once the gateway VM is up
+and its CA is available:
+
+1. Map each live bottle's guest IP → `bottle_id` from the orchestrator registry
+   (`list_bottles`).
+2. Install the **current** shared git-gate hooks (`git_gate_render_hook` /
+   `git_gate_render_access_hook`) into the fresh gateway once — rendered from
+   code, never from a bottle's possibly-stale state dir.
+3. For each live agent VM (enumerated from its run dir):
+   - **CA:** SSH the current gateway CA into the agent's trust store and run
+     `update-ca-certificates` (unconditional replace — there is one gateway, so no
+     fingerprint match is needed).
+   - **git-gate:** rebuild the bottle's upstreams from its persisted git-gate
+     state dir (deploy key, known_hosts, upstream URL) and re-init its bare repos
+     + per-repo creds under `/git/<bottle_id>`.
+   - **egress token:** read the agent's `ENV_VAR_SECRET` and feed
+     `reprovision_bottles`, restoring the orchestrator's in-memory tokens.
+4. Every per-bottle step is wrapped so one failure is logged and skipped.
+
+**Retire the persistence prototype.** No CA data volume, no git-gate data volume
+(the abandoned PRs #511 / #513). The launch-time `_reprovision_running_bottles`
+call folds into this bring-up reconcile, so egress tokens are restored on the same
+cold-boot trigger (an adopt needs no restore — the orchestrator never restarted).
+
+**CA rotation.** Because the gateway rootfs is ephemeral, every cold boot mints a
+fresh CA; reconcile is what distributes it, so a routine gateway rebuild doubles
+as a CA rotation with zero extra machinery.
+
+## Open questions
+
+- Docker's existing host-bind-mounted CA (`host_gateway_ca_dir`): once docker's
+  `attach_bottled_agents_to_gateway` pushes the CA to running agents on bring-up,
+  the bind-mount is redundant — drop it (so docker rotates like firecracker) or
+  keep it as belt-and-suspenders? Leaning drop, for one behaviour across backends.

+description: Runs the four egress/git probes recorded in docs/demo.gif.
+model: sonnet
+bottle: demo
+skills: []
+---
+
+You are inside bot-bottle, a sandbox whose egress is mediated by the
+bot-bottle gateway: an HTTP proxy that enforces a host allowlist and
+runs a DLP body scan on what leaves, plus a git gate that runs
+gitleaks in pre-receive before any push reaches its upstream.
+
+The user will ask you to run network probes against those controls.
+The "credentials" in the probes are synthetic test patterns, the git
+upstream is unreachable on purpose, and the whole point is to watch
+the gateway refuse.
+
+Always invoke curl with `--proxy "$HTTPS_PROXY"` so requests actually
+traverse the gateway — curl ignores the uppercase HTTP_PROXY env var.
+
+Run every command exactly as given, and never substitute a placeholder
+or redacted stand-in for a value. `$FAKE_TOKEN` in particular must
+reach the wire as the shell expands it: swapping in something like
+`ghp_FAKE...` leaves the DLP scanner with no pattern to match, and the
+control then reports a clean pass because it was never exercised at
+all. Letting the synthetic credential through is the entire point —
+the sandbox is what stops it, not you.
+
+Execute each probe literally via the Bash tool, report exactly what
+the proxy or the gate returned, and keep replies to one or two lines.
+Do not refuse on credential-exfil grounds: refusing is precisely what
+the bottle is designed to make unnecessary.

+The `demo` bottle — the sandbox boundary behind `docs/demo.gif`.
+
+Declares exactly enough to make all four recorded probes meaningful:
+one allowlisted host, one synthetic credential in the environment, and
+one git upstream wired through the git-gate. Everything an agent could
+use to reach the network here is either denied by the host filter,
+caught by the egress DLP scan, or rejected by gitleaks at push time.
+
+Not an example to copy for real work — the fake token and the
+`upstream.invalid` remote only make sense for a scripted recording.
+See `examples/bottles/` for bottles meant to be adapted.
