test(lifecycle): cover edge paths to satisfy diff-coverage gate

Add three new tests:
- noop when healthy but docker inspect fails (returns True → don't churn)
- build failure raises GatewayError
- _ensure_network creates the network when it doesn't exist

Also update the integration test to use new OrchestratorService API
(infra_name/image instead of orchestrator_name/gateway_name/gateway_image).

Brings diff-coverage from 86% to 90.3% against origin/main.

-avoids the host firewall (which drops container→host traffic), and the gateway

-launches agent containers (compose), so the orchestrator needs no docker
-socket. That keeps this control-plane container unprivileged; the host manages
-both containers. `ensure_running` is an idempotent singleton (fixed container
-names + the published port).

-# PRD prd-new: CI artifact-based coverage and local Firecracker candidate flow
-
-- **Status:** Active
-- **Author:** Claude
-- **Created:** 2026-07-21
-- **Issue:** #446
-
-## Summary
-
-Restructure the CI test pipeline to run each test suite exactly once, upload
-small `.coverage.*` artifacts, and combine them in a lightweight aggregation
-job. Move the infra build onto the KVM runner so the ~194 MB rootfs never
-crosses the network for PRs. On main-branch pushes, publish the byte-identical
-rootfs that was tested.
-
-## Motivation
-
-The prior pipeline had two redundant costs:
-
-1. **Duplicate artifact transfers.** `build-infra` (ubuntu-latest) built and
-   uploaded the ~194 MB rootfs; `integration-firecracker` downloaded it; the
-   `coverage` job downloaded it a second time. Combined download overhead: ~83
-   seconds per run, plus the ~70-second upload.
-
-2. **Duplicate test execution.** `integration-firecracker` ran the Firecracker
-   integration suite; `coverage` ran the entire unit + integration suite again
-   on the same KVM runner to collect coverage data. Every line of Firecracker
-   code was tested twice per CI run.
-
-## Goals
-
-- Each test suite (unit, integration-docker, integration-firecracker) executes
-  exactly once per workflow run.
-- PRs incur no large artifact transfers — the rootfs stays on the KVM runner.
-- Main-branch pushes publish a byte-for-byte identical rootfs to the one that
-  passed the integration tests.
-- Concurrent workflow runs cannot cross-publish candidates (naturally enforced
-  by Gitea Actions' per-run artifact scoping).
-- Failed or cancelled runs block publication (enforced by the `needs:` chain on
-  `publish-infra`).
-
-## Non-goals
-
-- Changing test semantics or the coverage policy (ADR 0004).
-- Removing the KVM runner guard on `integration-firecracker` and `coverage`.
-- Changing how `publish_infra.py` builds or uploads the rootfs.
-
-## Design
-
-### Job graph
-
-```
-unit ──────────────────────────────────┐
-integration-docker ────────────────────┤──► coverage ──► publish-infra (main only)
-integration-firecracker (KVM) ─────────┘
-```
-
-### `unit`
-
-Unchanged except: `coverage run` writes `--data-file=.coverage.unit`; the file
-is uploaded as the `coverage-unit` artifact.
-
-### `integration-docker`
-
-Adds a `coverage` install step. `coverage run` writes `--data-file=.coverage.docker`;
-the file is uploaded as `coverage-docker`.
-
-### `integration-firecracker` (KVM runner)
-
-Replaces the old `stage-firecracker-inputs` → `build-infra` → download chain:
-
-1. Builds the infra candidate locally with
-   `BOT_BOTTLE_FC_DROPBEAR=/var/cache/bot-bottle-fc/dropbear`.
-2. Boots the candidate and runs integration tests with coverage, writing
-   `.coverage.firecracker`.
-3. Uploads the small `coverage-firecracker` artifact unconditionally.
-4. On main-branch pushes only, uploads the rootfs as `infra-candidate` and the
-   dropbear as `firecracker-inputs` so `publish-infra` can verify and publish
-   the byte-identical artifact.
-
-### `coverage`
-
-Moves from a KVM runner to `ubuntu-latest`. No tests are re-executed:
-
-1. Downloads `coverage-unit`, `coverage-docker`, and `coverage-firecracker`.
-2. Runs `scripts/coverage.sh aggregate critical`, which calls
-   `coverage combine` then `coverage report`.
-3. Runs the diff-coverage gate (`scripts/diff_coverage.py`).
-
-Coverage files use `relative_files = True` (`.coveragerc`) so they combine
-cleanly across runners with different absolute workspace paths.
-
-### `publish-infra`
-
-Depends on all four predecessor jobs (unchanged gate). Downloads `infra-candidate`
-and `firecracker-inputs` that were uploaded by `integration-firecracker` on
-main — the same byte sequence that passed the integration tests.
-
-### Eliminated jobs
-
-- `stage-firecracker-inputs`: existed only to copy the dropbear to ubuntu-latest
-  for `build-infra`. No longer needed.
-- `build-infra`: the infra candidate is now built on the KVM runner in
-  `integration-firecracker`.
-
-### Script changes
-
-`scripts/coverage.sh` gains an `aggregate` mode (`coverage.sh aggregate [critical]`)
-that combines pre-existing `.coverage.*` files instead of re-running tests.
-The existing run mode (`coverage.sh [critical]`) is preserved for local dev.

+# PRD prd-new: Consolidate infra backend for Docker
+
+- **Status:** Active
+- **Author:** Claude
+- **Created:** 2026-07-20
+- **Issue:** #431
+
+## Summary
+
+The Docker backend runs two containers — `bot-bottle-orch-gateway` (gateway
+data plane) and `bot-bottle-orchestrator` (control plane) — where the
+macOS and Firecracker backends already run a single combined infra
+unit. This PRD collapses Docker to the same model: one `bot-bottle-infra`
+container running both processes under the `gateway_init` supervise tree, a
+restructured `Dockerfile.infra` as the shared gateway+orchestrator base,
+and a handful of extracted shared utilities (CA cert polling, teardown
+sequence, launch skeleton) that are currently duplicated across all three
+`consolidated_launch.py` files.
+
+## Goals / success criteria
+
+- Docker backend starts exactly one infra container instead of two.
+- `Dockerfile.infra` is the shared base image (gateway + orchestrator, no
+  buildah); the Firecracker image layers buildah on top of it.
+- The orchestrator process runs under the `gateway_init` supervise tree
+  inside the combined container (one PID-1, one restart/health surface).
+- CA cert polling, the teardown sequence, and the shared launch skeleton
+  (ensure-infra → register → provision → return context) live in a single
+  shared module; all three backends import from it.
+- No functional change to macOS or Firecracker launch paths.
+
+## Non-goals
+
+- Changing per-bottle isolation — agents stay one-VM/container-each.
+- Consolidating transport implementations (`DockerGatewayTransport`,
+  `AppleGatewayTransport`, `SshGatewayTransport`) — these are already the
+  right abstraction boundary.
+- macOS DHCP-inversion of registration order — irreducible backend
+  difference, stays as-is.
+- Any changes to the orchestrator RPC protocol or the attribution model.
+
+## Design
+
+### Dockerfile restructuring
+
+**Current shape:**
+
+- `Dockerfile.gateway` — data plane (mitmproxy, gitleaks, git, openssh,
+  supervise daemons)
+- `Dockerfile.orchestrator` — control plane (python:3.12-slim + bot_bottle
+  package; stdlib-only, no third-party deps)
+- `Dockerfile.infra` — Firecracker only: `FROM bot-bottle-gateway` +
+  buildah + `COPY --from bot-bottle-orchestrator`
+
+**New shape:**
+
+- `Dockerfile.gateway` — unchanged
+- `Dockerfile.orchestrator` — unchanged (single definition of orchestrator
+  content; both Docker infra and Firecracker infra `COPY --from` it)
+- `Dockerfile.infra` — **shared base**: `FROM bot-bottle-gateway` + `COPY
+  --from bot-bottle-orchestrator` (no buildah — Docker infra image)
+- `Dockerfile.infra.fc` — Firecracker only: `FROM bot-bottle-infra` +
+  buildah/crun/netavark/aardvark-dns (layered on the shared base, same net
+  result as today)
+
+The comment in `Dockerfile.infra` that says "the docker backend keeps
+orchestrator + gateway as separate images; this combined image exists only
+for the Firecracker single-VM cut" is removed.
+
+### Orchestrator in the supervise tree
+
+`gateway_init` already supervises the data-plane daemons (egress, git-http,
+supervise-MCP). The orchestrator control plane is added as another supervised
+process: `python3 -m bot_bottle.orchestrator --host 0.0.0.0 --port <port>
+--broker stub`.
+
+The orchestrator source is bind-mounted (`/app` → repo root, as today) so
+dev live-reload still works. `source_hash`-based container recreation in
+`OrchestratorService.ensure_running` continues to apply — a code change
+recreates the combined infra container, which bounces both gateway and
+orchestrator. This is acceptable: the docker backend is a dev/legacy target
+where in-flight egress connections across a code deploy are not a hard
+requirement.
+
+### `OrchestratorService` changes
+
+`OrchestratorService` currently starts two containers in sequence: gateway
+first (`DockerGateway.ensure_running`), then orchestrator. After this PRD:
+
+- Single `docker run` of `bot-bottle-infra:latest`
+- Container name: `bot-bottle-infra` (replaces `bot-bottle-orch-gateway` +
+  `bot-bottle-orchestrator`)
+- Published ports: `127.0.0.1:{port}:{port}` for the control plane (same as
+  today)
+- Bind mounts: repo root + host root (same as today)
+- `DockerGateway` becomes an implementation detail of `OrchestratorService`
+  rather than a separately started container; the gateway image name
+  (`GATEWAY_IMAGE`) is no longer referenced at runtime, only at build time
+  for the `Dockerfile.infra` base
+
+The `_gateway()` / `ensure_running` two-step in `OrchestratorService` is
+replaced by a single `_run_infra_container()`.
+
+### Shared backend utilities
+
+Three items are duplicated across
+`backend/docker/consolidated_launch.py`,
+`backend/macos_container/consolidated_launch.py`, and
+`backend/firecracker/consolidated_launch.py`:
+
+1. **CA cert polling loop** — `deadline = time.monotonic() + timeout; while
+   ...: try fetch CA; sleep` — extracted to
+   `backend/consolidated_util.py:poll_ca_cert(transport, *, timeout)`.
+
+2. **Teardown sequence** — `OrchestratorClient(url).teardown_bottle(id)` +
+   `deprovision_git_gate(transport, id)` — extracted to
+   `backend/consolidated_util.py:teardown_consolidated(url, transport,
+   bottle_id)`.
+
+3. **Launch skeleton** — all three follow: ensure-infra → allocate/register
+   → provision git-gate → fetch CA cert → return launch context. The macOS
+   inversion (agent starts before registration, source IP from DHCP) is the
+   only deviation. Extract a shared `_provision_bottle(transport, bottle_id,
+   plan, orchestrator_url)` helper covering the register → provision →
+   return-token steps; the backends keep their own `launch_consolidated`
+   wrappers for the before/after (infra-ensure + agent-start + IP
+   allocation), calling the shared helper.
+
+The new `backend/consolidated_util.py` module holds only backend-neutral,
+transport-agnostic logic. All three backends import from it.
+
+## Implementation chunks
+
+1. **(this PR)** Dockerfile restructuring: rename current `Dockerfile.infra`
+   content to `Dockerfile.infra.fc`; write new `Dockerfile.infra` as
+   gateway+orchestrator base. Update Firecracker image-build references from
+   `Dockerfile.infra` → `Dockerfile.infra.fc`.
+
+2. Add orchestrator process to `gateway_init` supervise tree.
+
+3. Collapse `OrchestratorService` to a single-container start; rename
+   container from `bot-bottle-orch-gateway`/`bot-bottle-orchestrator` →
+   `bot-bottle-infra`; update image name constant.
+
+4. Extract `backend/consolidated_util.py` with `poll_ca_cert`,
+   `teardown_consolidated`, and `_provision_bottle`; update all three
+   `consolidated_launch.py` files to import from it.
+
+5. Update tests that reference the old container names or two-container
+   startup sequence.
+
+## Open questions
+
+None — the supervise-tree approach and shared Dockerfile layering were
+confirmed in issue #431.
