Now that #469 got the DB off the data plane, the docker backend runs the
control plane and data plane as two containers instead of the combined
`bot-bottle-infra` container:
* bot-bottle-orchestrator — the lean control-plane container (image
Dockerfile.orchestrator, `-m bot_bottle.orchestrator`). Joins the new
`bot-bottle-orchestrator` control network (`--internal`) only, plus a
host-loopback publish for the CLI. Sole opener of bot-bottle.db; holds the
signing key; no CA, no gateway daemons.
* bot-bottle-orch-gateway — the data-plane container (DockerGateway),
dual-homed on the agent `bot-bottle-gateway` network AND the control
network, so it resolves the orchestrator by name
(http://bot-bottle-orchestrator:8099) while agents — never on the control
network — have no route to the control plane (the L3 block, not just the
JWT). Holds the gateway JWT + the mitmproxy CA.
DockerInfraService now orchestrates the pair (builds gateway + orchestrator
images, brings up the orchestrator then the gateway) and exposes gateway_name;
the launch flow attributes agents against the gateway container. DockerGateway
gains a control_network it joins after run. rotate_ca / the CA read target the
gateway container. The combined Dockerfile.infra is no longer built by docker
(firecracker/macOS still use it until their splits).
pyright 0 errors; unit suite green (2273). Integration tests updated for the
two-container shape but need a real-docker run to validate the networking.

Brings in main's 8 commits — #470 (backend-agnostic CI guards: BackendStatus
enum, quiet status(), is_backend_available/is_backend_ready, tests/_backend.py
skip_unless_backend) plus firecracker status() readiness checks (kvm/kernel/
dropbear/mke2fs).
Reconciled #470's additions into the reorg'd backend structure:
* BackendStatus enum + the status(*, quiet=) ABC signature -> backend/base.py
* is_backend_available / is_backend_ready -> backend/selection.py
* exposed all three through the lazy backend facade (__init__).
Integration-test conflicts were our control_plane->orchestrator renames vs
main's skip_unless_docker -> skip_unless_backend swap: kept our refactored
import paths + main's guard. Repointed main's new is_backend_* tests to patch
selection._backends (our moved home) instead of the facade.

Two reviewer findings addressed:
1. _kvm_accessible() now opens /dev/kvm with O_RDWR|O_CLOEXEC instead
of read-only. VM creation requires write access; a read-only
descriptor can satisfy KVM_GET_API_VERSION but fails at boot time.
2. status() now checks every hard prerequisite that require_firecracker()
checks at launch: guest kernel image, static dropbear binary, and
mke2fs. Previously a host with a configured TAP pool but missing
artifacts could pass status() and then fail during launch.
Regression coverage: TestFirecrackerKvmCheck gains test_kvm_open_rdwr_fails;
TestFirecrackerArtifactCheck covers each missing artifact; existing
TestFirecrackerStatus fixtures updated to stub the new checks.

Adds `_firecracker_binary_ok()` (runs `firecracker --version`) and
`_kvm_accessible()` (opens /dev/kvm, issues KVM_GET_API_VERSION ioctl)
and gates `status()` on both, so the launch preflight reports missing
binary or inaccessible KVM before the caller ever attempts a boot.
Regression tests in TestFirecrackerBinaryCheck, TestFirecrackerKvmCheck,
and TestFirecrackerStatusRuntime cover all branches. Updated the
pre-existing TestFirecrackerStatus fixture to also stub the two new
helpers so it still exercises only the tap-pool/nft logic it was
designed for.

Add a module-level BackendStatus(IntEnum) with READY=0 to replace magic
0 comparisons. Extend BottleBackend.status() with a quiet parameter:
quiet=False (default) prints diagnostics; quiet=True returns the code
silently for programmatic checks.
Add is_backend_available() (cheap PATH check, alias for has_backend) and
is_backend_ready(name, *, quiet=False) (full status() check) to the
backend package for callers that need to distinguish availability from
readiness.
Update tests/_backend.py guards to use is_backend_ready(quiet=False) so
diagnostic output is printed during test discovery, giving the operator a
concrete reason for each skip rather than a bare "prerequisites
unavailable" message.

Reimplements the dropped firecracker fix on the refactored code, addressing
didericis-codex's blocking review on #471.
The previous firecracker path let the VM generate its own signing key on the
guest volume and had `_with_signing_key()` unconditionally overwrite the single
host-wide orchestrator-token with it. That breaks a co-running Docker/macOS
control plane: their orchestrators still verify with the old key while new host
clients start signing `cli` tokens with the guest key, so
supervise/teardown/policy calls against those backends begin returning 401
(cross-backend operation is supported).
Keep the host token file the single source of truth. The launcher now pushes the
host-canonical key into the freshly booted infra VM over SSH (atomic write,
mirroring persist_env_var_secret) via `_push_signing_key()`; the VM's init waits
for it and refuses to start the control plane — rather than run OPEN — if it
never arrives. Nothing writes back to the host file, so other backends are
untouched, and the best-effort silent path is gone (both the push and the guest
fail loudly).

Brings in the two commits main gained: #472 (CLI cleanup — remove `info`,
split `list active` into a top-level `active`, simplify `list`) and the
terminology glossary. #472 was written against the old flat cli/ layout,
so its semantics are reconciled into the reorg'd cli/commands/ structure:
* new `active` command lives at cli/commands/active.py, registered in
the lazy registry and listed in `help` (not left at the flat path).
* `info` removed: deleted cli/commands/info.py, dropped from the
registry and `help`.
* `list` simplified to list-available-only, using the reorg's
os.getcwd()/constants.PROG conventions.
* the `list active` -> `active` doc wording applied to the backend
docstrings that our split moved into base.py / selection.py.
Our reorg wins for the fully-rewritten dispatcher (cli/__init__ shim,
backend facade). pyright: 0 errors. Full unit suite green (2243).

The codebase used "control plane" both as an architectural role term AND
as an identifier alias for the orchestrator component, producing
duplicate names for one thing (control_plane_url vs orchestrator_url,
CONTROL_PLANE_PORT, host_control_plane_token, …). Going forward the
concrete component is always named for what it is — Gateway or
Orchestrator — and the plane vocabulary is reserved for prose (module
descriptions, the security argument).
Renamed (identifiers + the in-repo env/wire/file string values, all
setters/getters are in this repo so the change is atomic):
ControlPlaneServer -> OrchestratorServer
control_plane_url -> orchestrator_url
probe_control_plane_url -> probe_orchestrator_url
host_control_plane_token -> host_orchestrator_token
CONTROL_PLANE_PORT -> ORCHESTRATOR_PORT
CONTROL_PLANE_TOKEN_ENV/FILE -> ORCHESTRATOR_TOKEN_ENV/FILENAME
BOT_BOTTLE_CONTROL_PLANE_TOKEN-> BOT_BOTTLE_ORCHESTRATOR_TOKEN
control-plane-token (file) -> orchestrator-token
control_auth (module) -> orchestrator_auth (stays top-level;
the gateway imports it and must not
import the orchestrator/ package)
CONTROL_AUTH_HEADER -> ORCHESTRATOR_AUTH_HEADER
x-bot-bottle-control-auth -> x-bot-bottle-orchestrator-auth
CONTROL_AUTH_JWT_ENV -> ORCHESTRATOR_AUTH_JWT_ENV
BOT_BOTTLE_CONTROL_AUTH_JWT -> BOT_BOTTLE_ORCHESTRATOR_AUTH_JWT
_control_auth_headers -> _orchestrator_auth_headers
Prose plane-terms ("control plane", "data plane") are preserved,
including the test name test_data_plane_daemons_get_jwt_not_key (it
names the security invariant). Gateway and orchestrator verified to
agree on the renamed wire header; full unit suite green (2243).

egress_entrypoint.sh is the mitmdump launcher for the egress data plane,
so it belongs with the gateway egress service, not at the package root.
Moved to bot_bottle/gateway/egress/entrypoint.sh (prefix stripped now
that the package namespaces it).
Only the Dockerfile.gateway COPY source changes; the runtime target
(/app/egress-entrypoint.sh, referenced by bootstrap's egress DaemonSpec)
is unchanged, and the infra images inherit it via FROM gateway. Updated
the test that resolves the script path and the infra-artifact docstring
example. Full unit suite green (2243).

Group the gateway's data-plane modules into three service sub-packages
mirroring the host-side trio (bot_bottle.egress / .supervisor / .git_gate):
gateway/egress/ addon_core, addon, dlp_config, dlp_detectors
gateway/supervisor/ server (was supervise_server)
gateway/git_gate/ render, http_backend
Prefix-stripped filenames now that the package namespaces them; each
sub-package has a thin docstring __init__ (no eager imports, cheap leaf
loads). The two cross-cutting files stay at the gateway root:
policy_resolver (shared per-client lookup) and gateway_init, renamed to
bootstrap now that gateway/ already namespaces it.
Updated all importers (bot_bottle + tests), the in-VM/container `-m`
launch strings, the Dockerfile.gateway addon shim + ENTRYPOINT, and the
five gateway entries in scripts/critical-modules.txt. Full unit suite

Split the flat egress.py into an egress/ package: neutral DTOs
(EgressRoute, EgressPlan) in plan.py, and the concrete Egress service
class plus rendering/env helpers in service.py, behind a thin
__getattr__ facade so leaf imports stay cheap.
Egress drops ABC and becomes a concrete service the backends call:
resolve_token_values / agent_env_entries / prepare are now methods.
Backend launch paths (docker, firecracker, macos_container) call
Egress().<method>(...) instead of the module-level functions.

Turn the git_gate module into a package with GitGate as a concrete service class
(dropping the ABC), mirroring the Supervisor shape. The host-side git-gate
operations are now methods the backend drives:
git_gate/
__init__.py — thin __getattr__ facade (keeps `from bot_bottle.git_gate
import …` working; render/hook names lazily forwarded to
gateway.git_gate_render)
plan.py — GitGatePlan (the launch DTO the backend contract references)
service.py — GitGate: prepare / provision_dynamic_keys /
revoke_provisioned_keys / preflight_host_keys
provision.py — deploy-key lifecycle (was git_gate_provision.py)
host_key.py — host-key preflight (was git_gate_host_key.py)
The backend launch + base.py preflight now call GitGate() methods instead of the
free functions. The runtime rendering / in-gateway hook execution stay in
gateway/git_gate_render.py (data plane) — only the host-side service moved.
Because the facade forwards names lazily, the ~25 `from bot_bottle.git_gate
import GitGatePlan` call-sites are unchanged, and importing git_gate.plan (the
contract's dependency) no longer drags in the provisioning / forge-API code.

docker_cmd.py existed as a top-level module solely so the orchestrator's docker
components could share run_docker without dragging the (then-heavy) backend
layer in. Now that backend/__init__ and backend/docker/__init__ are thin,
importing backend.docker.util costs 6 modules instead of 76, so the shim's whole
reason to exist is gone.
Move run_docker into backend/docker/util.py (where the other docker subprocess
primitives live) and delete docker_cmd.py. Backend siblings import it via
`from .util import run_docker`; the two docker-specific orchestrator modules
(docker_broker, rotate_ca) import `from ..backend.docker.util import run_docker`.
No import cycle (backend.docker.util pulls nothing from orchestrator);
orchestrator.__main__ stays lean at 28 modules. run_docker patch targets are
unchanged (tests patch it in the importing module).

The three concrete-backend package inits eagerly imported their
`*BottleBackend` (which pulls the whole framework), so importing any leaf under
them (e.g. `backend.docker.util`) paid ~78 modules. Give each the same thin
`__getattr__` treatment as the top-level backend package: re-export the public
class(es) lazily on first access, with a TYPE_CHECKING block for checkers.
`import bot_bottle.backend.docker.util` drops from 78 -> 6 bot_bottle modules;
the docker/firecracker/macos-container packages themselves are ~3 each. All
`from bot_bottle.backend.docker import DockerBottleBackend` call-sites and the
lazy selection path keep working.
This is what makes backend leaves cheap — and unblocks moving docker_cmd into
backend/docker/util if we want.

backend/__init__.py eagerly imported the whole framework (manifest, egress,
git-gate, env, workspace, agent-provider), so importing ANY backend.* submodule
paid ~32 modules just to run the package init. Split it:
- backend/base.py — the abstract contract (BottleSpec, BottlePlan,
BottleCleanupPlan, ExecResult, ActiveAgent, Bottle,
BottleImages, BottleBackend). Carries the framework
imports; loaded only when a caller needs the contract.
- backend/selection.py — backend registry / selection / enumeration
(get_bottle_backend, _get_backends, _auto_select_backend,
has_backend, known_backend_names, enumerate_active_agents).
Concrete backends still imported lazily inside.
- backend/__init__.py — thin: a __getattr__ that resolves the public names
from those submodules on first access (+ a TYPE_CHECKING
block for checkers). Existing `from bot_bottle.backend
import X` and patch.object call-sites keep working.
`import bot_bottle.backend` drops from 32 -> 2 bot_bottle modules. Repointed the
backend-selection test's patch targets to the `selection` module (the functions
reference each other there now; the FirecrackerBottleBackend class-method
patches are unchanged — same class object).
Note: backend.docker.util is still heavy because backend/docker/__init__ eagerly
imports DockerBottleBackend — slimming the three sub-package inits is the
follow-up that makes the leaves cheap.

OrchestratorService wasn't the orchestrator — it's the host-side lifecycle of
the docker infra *container* (the one that runs the Orchestrator). It read as
"the orchestrator as a service" and lived in orchestrator/lifecycle.py, while
its siblings (macOS MacosInfraService, Firecracker infra_vm) live under their
backend package. Rename it DockerInfraService and move it to
backend/docker/infra.py alongside the docker backend, with its docker-only
constants (INFRA_*/ORCHESTRATOR_* image + container names, daemon list, mount
paths).
orchestrator/lifecycle.py keeps only the backend-neutral pieces the other infra
services share — DEFAULT_PORT, DEFAULT_STARTUP_TIMEOUT_SECONDS,
OrchestratorStartError, source_hash — which macOS / firecracker / client still
import from there. backend/docker/infra.py imports those (backend -> orchestrator
is an allowed direction). Renamed the unit test to test_docker_infra.py.

Move the `Supervise` lifecycle out of its own `orchestrator/supervisor/
supervise.py` and into the package `__init__`, renaming the class to
`Supervisor`. Callers now import it from `bot_bottle.orchestrator.supervisor`
alongside the queue surface it belongs with.
Remove the dead `try/except ImportError` flat-import fallbacks from the
package-only store modules (db_store, audit_store, config_store, queue_store)
and image_cache. Those fallbacks existed for when the store files were
flat-copied into the gateway; post-PRD-0070 the data plane never opens the DB,
so these modules are only ever imported as part of the package. The two gateway
data-plane files that may still be loaded flat (egress_addon_core,
git_gate_render) keep their fallbacks.

Give each service its own store package + manager, and cut the supervise module
along the control/data-plane boundary so nothing in the shared layer reaches up
into the orchestrator.
Stores, by owner:
- bot_bottle/store/ keeps only the shared base (DbStore, migrations) and the
concrete stores that aren't service-owned (audit_store, config_store).
- bot_bottle/orchestrator/store/ now houses the orchestrator-owned stores —
queue_store (supervise queue), secret_store, config_store — plus a new
orchestrator store_manager that migrates them (composing audit/config
downward from the base). The old shared store_manager is gone.
Supervise plane, by tier:
- bot_bottle/supervisor/ (NEUTRAL, importable by every tier including the
gateway): types.py (the Proposal/Response/AuditEntry wire types + the tool/
status/poll constants + the shared daemon constants moved out of
supervise.py) and plan.py (SupervisePlan, a pure DTO).
- bot_bottle/orchestrator/supervisor/ (orchestrator-only): queue.py (the
queue/audit I/O wrappers + render_diff + sha256_hex) and supervise.py (the
Supervise lifecycle that stages the DB via the store manager). Its __init__
re-exports the neutral vocabulary so orchestrator-side callers import from
one place.
The gateway now imports only bot_bottle.supervisor.types (never
bot_bottle.supervise), so the data plane holds no code dependency on the
orchestrator — it reaches the queue over the control-plane RPC. This removes
the circular import that moving queue_store under orchestrator introduced
(supervise -> orchestrator -> service -> supervise).
supervise_types.py -> supervisor/types.py; supervise.py deleted (split). Full
unit suite green (2251).

Separate the gateway (data plane) from the orchestrator (control plane) at the
module level. The gateway runtime files move out of the package root — and the
backend-neutral Gateway lifecycle ABC + GATEWAY_* constants move out of
orchestrator/ — into a new bot_bottle/gateway/ package:
gateway/__init__.py (was orchestrator/gateway.py: Gateway ABC + consts
+ rotate_gateway_ca)
gateway/gateway_init.py (the PID-1 daemon supervisor)
gateway/egress_addon.py, egress_addon_core.py, egress_dlp_config.py,
dlp_detectors.py (the egress mitmproxy daemon)
gateway/git_http_backend.py (the git-http daemon)
gateway/git_gate_render.py (the git-gate pre-receive rendering)
gateway/supervise_server.py (the supervise MCP daemon)
gateway/policy_resolver.py (the data-plane control-plane RPC client)
orchestrator/ now holds only control-plane files. The shared plan/types/auth
layer (egress.py=EgressPlan, git_gate.py=GitGatePlan, supervise.py,
supervise_types.py, control_auth.py) and the launch-time git-gate provisioning
helpers stay at root, so orchestrator/ and backend/ still own them.
Because these daemons are invoked as `python3 -m bot_bottle.<name>`, loaded flat
by mitmproxy, and referenced in Dockerfile.gateway, the move updates more than
Python imports: the `-m` invocations (firecracker/macOS infra scripts), the
Dockerfile.gateway addon shim + ENTRYPOINT, gateway_init's _DAEMONS module
paths, and the git-gate CGI heredocs all now point at bot_bottle.gateway.*.

The `DockerGateway` container-lifecycle impl now lives in
`backend/docker/gateway.py` (the shape backend gateway classes will share);
`orchestrator/gateway.py` keeps only the backend-neutral pieces (the `Gateway`
ABC, constants, `rotate_gateway_ca`).
Delete the standalone-gateway path it was the only consumer of. `--gateway` on
`python -m bot_bottle.orchestrator` was invoked nowhere — the production docker
flow runs the gateway data plane inside the combined `bot-bottle-infra`
container via `OrchestratorService`, never this class. Removing it takes with it
`Orchestrator.ensure_gateway()` and the `gateway` ctor arg; `gateway_status()`
becomes a stub reporting `configured: false` so the documented `GET /gateway`
control-plane route keeps its contract.
Fix a latent bug the move surfaced: `launch.py` read the shared gateway CA via
`docker exec bot-bottle-orch-gateway`, a container the consolidated flow never
creates — so the agent CA install was reaching a nonexistent name. Read it from
`bot-bottle-infra` (INFRA_NAME) instead.
Repoint the affected tests to the new module; drop the unit test + fake that
covered the deleted standalone wiring.

The Firecracker infra VM started the control plane with no signing key, so it
ran open and granted every unauthenticated caller the `cli` role. The nft
boundary only fences off the separate agent VM — the egress / supervise /
git-http daemons run in this same VM and reach the orchestrator over 127.0.0.1,
so a compromised data-plane daemon could still drive the operator routes
(approve its own supervise proposals, rewrite policy, read injected tokens).
Generate the signing key on the persistent volume, hand it only to the
orchestrator process, mint a `gateway` JWT for the data-plane daemons, and
mirror the key back to the host token file so the CLI signs `cli` tokens the VM
verifies — the same per-process scoping the docker / macOS launchers use.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Review follow-up on #469: the data plane held the same control-plane secret
that authorizes every route, so a compromised egress/git-gate could queue a
supervise proposal AND approve it (or rewrite policy, read injected tokens) —
the (source_ip, identity_token) checks attribute the *bottle*, not the caller.
Replace the single shared bearer secret with role-scoped, HMAC-signed tokens
(compact HS256 JWTs, stdlib-only — no new dependency):
* new `control_auth` mints/verifies `{role}` tokens; roles are `gateway`
(data plane) and `cli` (host operator/launcher).
* the orchestrator holds only the signing *key* and verifies; `dispatch`
gates each route by role — `gateway` reaches /resolve + /supervise/
{propose,poll}, everything else is `cli`-only (401 unauthenticated,
403 wrong role).
* the gateway is handed a pre-minted `gateway` token it cannot rewrite into
`cli`; the host CLI mints its own `cli` token from the host key.
* `gateway_init` scopes the signing key to the orchestrator process and the
gateway token to the data-plane daemons, so even in the combined infra
container a compromised data-plane daemon never sees the key.
Launchers (docker gateway + infra, macOS infra) inject the minted token(s);
Firecracker stays open behind its nft boundary. Open mode (no key) still grants
full `cli` access — the fail-visible fallback for tests.

PRD 0070's rule — only the orchestrator opens bot-bottle.db; the data
plane reaches state through the control-plane RPC — was not in force.
Three data-plane daemons held a direct read-write handle on the shared
SQLite file: the supervise MCP server, the egress DLP addon (the most
attack-exposed process, TLS-bumping hostile traffic), and the git-gate
pre-receive hook. An RCE in any of them could read every bottle's
plaintext identity_token and forge attribution fleet-wide (issue #469).
Add the agent half of the supervise flow to the control plane:
POST /supervise/propose -> queue a proposal, 201 {proposal_id}
POST /supervise/poll -> non-blocking decision poll, 200 {status,...}
Both attribute the caller by (source_ip, identity_token) exactly like
/resolve — never a caller-supplied slug — so a bottle can only ever queue
or read its own proposals even if the data plane is compromised. A decided
poll archives server-side, preserving the archive-after-read contract.
Data plane: the supervise server, egress addon, and git-gate hook now
queue/poll through PolicyResolver.propose_supervise / poll_supervise
instead of opening the DB. supervise_server keeps its ~30s grace window
by polling the RPC; egress keeps its safelist keyed by resolved bottle;
the git-gate hook gets (source_ip, identity_token) from the CGI env.
Packaging: drop the DB bind-mount and SUPERVISE_DB_PATH from the
data-plane containers/VMs (docker gateway + infra, macOS infra,
firecracker infra). The orchestrator remains the sole opener of the one
file via BOT_BOTTLE_ROOT / host_db_path().
Update PRD 0070: the rule is now in force; remove the transitional caveat.

Implements the interim secret-provider design (PRD prd-new-secret-provider):
each agent receives a random ENV_VAR_SECRET injected into its container env
at launch. The host uses this key to encrypt each egress auth token value
(HMAC-SHA256 CTR mode, stdlib-only) and store it in a new
bottled_agent_secrets table (one row per env var, key column plaintext for
auditing). The key never touches the DB.
On infra container restart the in-memory token map is lost. launch_consolidated
now calls _reprovision_running_bottles after ensure_running: for each
registered bottle still alive on the gateway network it execs
`printenv ENV_VAR_SECRET` into the agent container and posts the result to the
new POST /bottles/<id>/reprovision_gateway control-plane endpoint, which
decrypts the stored rows and restores _tokens — no manual intervention needed.

This is the layer that actually decides it, and it was in the script
from the start: ~/.docker/config.json's proxies block is what the Docker
CLI copies into every container it starts. Being client-side it beats
the podman service outright, which is why containers.conf `env`,
http_proxy=false, and the service environment each looked correct on
disk and changed nothing a nested container saw.
Also corrects the comment on the service-env substitution, which
claimed to be the one place the address sticks. It is not; it covers
podman's own pulls and non-CLI API clients.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Third attempt at the same symptom, and the first at the right layer.
podman's Docker-compatible API injects proxy settings from the *daemon*
environment after containers.conf is applied, so neither the env list
(892bfc16) nor http_proxy=false (21c144ae) could override it — the same
compat-path blind spot already seen with hosts_file. Nested containers
kept reporting `wget: bad address 'bot-bottle-gateway:9099'` through
both.
Substituting the resolved address into the service's own environment,
before `podman system service` starts, is the one place it sticks.
NO_PROXY keeps the name, which is matched against what a client asks
for.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The address-bearing proxy URLs from 892bfc16 were written correctly but
never took effect: podman copies the host's proxy environment into every
container by default, and that copy overrides containers.conf `env`,
restoring the `bot-bottle-gateway` name a nested container cannot
resolve. Verified on the macOS host — containers still reported
`wget: bad address 'bot-bottle-gateway:9099'` with the addresses in
place.
Setting http_proxy=false disables only podman's own passthrough; the
proxy vars still reach containers, by address, from the env list.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
podman's containers.conf `hosts_file` turns out to apply only to native
`podman run`; the Docker-compatible API ignores it, and the agent types
`docker`. (`base_hosts_file`, used before this, is a no-op in both
paths on podman 5.4.2.) So no config key can put the gateway name in a
nested container's /etc/hosts.
The name is therefore resolved in the bottle, where /etc/hosts does
carry it, and the address goes into the proxy URL handed to nested
containers. NO_PROXY keeps the name, since that is matched against what
a client asks for.
Verified on the macOS host: with the gateway reachable, a nested
container gets 200 from an allowlisted host and 403 from one that is
not — the egress boundary applies inside nested containers too.

Answers the last open question in #392: DNS from inside a nested
container was not a phantom, but it was also not a DNS problem. Public
resolution fails there by design — everything egresses through the
proxy — and the actual breakage was two missing pieces:
- The proxy URL names `bot-bottle-gateway`, which resolves only through
the bottle's own /etc/hosts. Containers got their own hosts file, so
they failed at "Could not resolve proxy", which reads like broken DNS.
base_hosts_file propagates the bottle's entries.
- The gateway TLS-intercepts, so a container that does not trust the
bottle's CA bundle fails with "unable to get local issuer
certificate". The bundle is now mounted read-only and the usual env
vars point at it, which covers curl, wget, python, and node without
distro-specific trust commands.
Verified on the macOS host by reproducing each failure and confirming
that these three conditions applied by hand produced HTTP 200 from
inside a nested container. podman already forwards the proxy env, so
that needed nothing.

netavark shells out to `nft` for the bridge network every compose file
expects, and aardvark-dns serves name resolution inside nested
containers. Neither arrives with the base image's
`--no-install-recommends` podman, and each fails at a different and
misleading layer: without nft containers are created but never start;
without aardvark-dns DNS inside a container fails while the engine, the
pulls, and the bridge all look healthy. That last one is the likeliest
explanation for the "DNS inside nested containers fails entirely" note
in #392 — a missing package, not a design gap.
Verified on the macOS host: with passt alone, `docker run` reached
netavark and died on "unable to execute nft".

podman 5 uses pasta as the default rootless network helper; podman 4
used slirp4netns. The spike was written against bookworm's podman 4.3.1,
so its package list never included passt — and the trixie bump (#451)
changed the default out from under it. Every nested container failed to
start with "could not find pasta", while image pulls and the service
itself worked, which disguised a missing dependency as a compat-API bug.
The bootstrap now checks for pasta up front so this fails with a clear
message instead of surfacing at the first `docker run`.
Note the sun_path fix in a12d2191 did NOT cause or cure this; that path
was over the 108-byte limit independently and would have bitten as soon
as attach was reached.

podman derives conmon's attach socket as
`$XDG_RUNTIME_DIR/libpod/tmp/socket/<64-hex-id>/attach`. With the
descriptive `/tmp/bot-bottle-podman-run` that path is 116 bytes, past
the 108-byte sun_path limit, so every attached `docker run` failed with
"unable to upgrade to tcp, received 500" — while image pulls and the
service itself worked, which is what made it look like a compat-API bug
rather than a path-length one.
Found on the macOS host: quay.io pulled fine and then no container
could be started. Test pins the budget so a more readable name cannot
silently reintroduce it.

Adds the `nested_containers` bottle flag. On the macOS backend it starts
a rootless podman service inside the bottle and exposes its
Docker-compatible API socket, so the agent still runs `docker` and
`docker compose`. No host daemon socket is mounted and the guest gains
no capabilities; backends that cannot run a guest-local engine reject
the flag in the shared prepare template rather than ignoring it.
Podman rather than rootless Docker because Apple Container's capability
bounding set omits CAP_SYS_ADMIN, which the kernel requires to write a
multi-range uid_map via newuidmap. With no subordinate UID range podman
falls back to a single-UID self-mapping an unprivileged process may
write itself, so the image build strips /etc/subuid and /etc/subgid
entries rather than adding them.
That mapping is also why nested containers are not an isolation layer:
root inside one is the agent user outside it. They are a build/test
convenience; the bottle remains the boundary.
Ports the spike branch onto main, renaming docker_access — it implied
Docker and granted access to nothing on the host — and drops podman
from the derived layer now that every built-in image ships it (#451).

`cleanup()` enumerated *every* firecracker process under the run root and
*every* run dir, so `./cli.py cleanup` would kill running bottles and
delete their rootfs — despite being described as orphan cleanup. The
backend's `enumerate_active` registry is still a stub (#354), so there
was no live/dead signal.
Use the running firecracker processes themselves as that signal: a run
dir with a live VM is protected (never killed, never removed); only run
dirs with no live process (leaked by a hard-killed launch) are reaped,
plus firecracker pids whose run dir is already gone (lingering VMMs).
This makes cleanup safe to run alongside live bottles and lets it back a
periodic GC for the run-dir leak the launch.py teardown fix closes on the
clean-exit path.

Each Firecracker bottle created its run dir (holding an ~1G
rootfs.ext4) but never removed it — launch teardown only terminated
the VM. Every run leaked its rootfs, filling the CI runner's disk
(187 stale sandbox-tester dirs / 141G in one incident).
Register a run-dir rmtree callback on the ExitStack before the
vm.terminate callback so, LIFO, the VM is gone before its rootfs is
removed. ignore_errors keeps teardown resilient.

FROM-scratch images (commit_container output) and registry images built
for reproducibility often omit the created field entirely. Both backends
were calling die() in that case, crashing the cached-image quickstart
before any container started.
image_created_at now returns datetime | None — None when the field is
absent or unparseable, die() only on real inspect failures (non-zero
exit, malformed JSON). stale_checks in both backends skips the staleness
check when None is returned.

pyright strict reportUnusedImport flagged BottleImages in
test_docker_launch_committed_image.py and test_macos_container_launch.py;
neither file references the type by name (they only use the returned
value's attributes).
`from __future__ import annotations` already defers all annotation
evaluation, so quoting `str | Path`, `BottleImages` inside the same
module was redundant and tripped pyright strict mode.
Addresses review comments 3098, 3099, 3100 on PR #336:
- Add BottleImages(agent, sidecar) dataclass to backend/__init__.py.
Docker/macOS backends use str image refs; smolmachines uses Path
artifacts. Replaces the singular `image` variable from the canonical
pattern in comment 3100.
- Replace _image_stale_checks/skip_stale with public prelaunch_checks().
CLI now calls backend.prelaunch_checks(plan) before backend.launch(plan);
if StaleImageError is raised and the operator confirms, launch proceeds
without re-checking. Removes the while-True/skip_stale retry loop.
- Add abstract _build_or_load_images(plan) -> BottleImages to
BottleBackend. launch() calls it then passes images to _launch_impl.
Each backend implements both methods.
- Fix comment 3098 (macos-container): _build_images is removed.
build_or_load_images() has separate fresh/cached code paths — the
cached path never calls a build helper.
- Update _start_bundle (smolmachines) to accept sidecar_artifact: Path
directly. Sidecar artifact resolution moves to _sidecar_from_path(),
called by build_or_load_images alongside _agent_from_path().
- image_cache: StaleImageError exception + check_stale/check_stale_path (raise instead of warn)
- BottleBackend.launch: template method (skip_stale flag) that calls _image_stale_checks then _launch_impl
- Each backend: _image_stale_checks delegates to a stale_checks() function in its launch module; _launch_impl replaces launch override
- macos_container: adds image_created_at to util, cached-image support in _build_images, stale_checks
- cli/start.py: catches StaleImageError, prompts interactively, retries with skip_stale=True; headless mode dies on it
coverage run's --data-file flag can be overridden or ignored in some
runner environments (Nix Python, older act-based runners). Switching to
the COVERAGE_FILE env var with an absolute ${{ github.workspace }} path
ensures coverage.py writes to a known location in every runner context,
so upload-artifact can find the file.
Also adds --reuse-published to the infra build step: if the artifact for
this content hash already exists in the registry, download it instead of
running the full docker build → mke2fs → gzip pipeline.
Extract the shared CA cert polling loop into `backend/util.poll_ca_cert`
(firecracker and macos backends were duplicating deadline/sleep/raise logic).
Each caller now wraps a fetch lambda and converts TimeoutError to its own
error type. Also corrects the PRD port publication line from {port}:{port}
to {host_port}:8099.
