Container-level counterpart to the ensure_built cache-aware fix. ensure_built
now rebuilds the gateway image on a source change, but ensure_running still
reused an already-running container built from the OLD image — so a rebuild
(even BOT_BOTTLE_NO_CACHE) never took effect on a warm gateway, and it kept
running the pre-fix flat daemons (this is why token injection stayed broken
after the rebuild). ensure_running now compares the running container's image
to the current image and recreates on mismatch. Validated on docker: a stale
gateway is detected and recreated with the current image + new egress addon.

The cut-over dropped the per-bottle token flow, so an authed egress route on
the shared gateway failed with 'env var EGRESS_TOKEN_0 is unset' — the gateway
reads the token from its env, but a shared gateway has no per-bottle env.
Now the bottle's egress auth tokens travel to the gateway over /resolve and
the addon injects from them, mirroring what the per-bottle sidecar's env did:
- launch resolves the token values from the host env and hands them to the
orchestrator, which holds them IN MEMORY (keyed by bottle_id, never written
to the registry DB) and serves them on /resolve;
- PolicyResolver.resolve_policy_and_bottle_id + resolve_client_context now
return the token map alongside policy + bottle_id (one round-trip);
- the egress addon overlays the process env with the bottle's tokens per
request and uses that env for auth injection AND DLP — the agent never sees
the credential.
Secrets stay off disk (validated: /resolve returns the token, the registry DB
does not contain it). SecretProvider (#355) is the future hardening.

On a fresh gateway container, mitmproxy writes mitmproxy-ca-cert.pem a beat
after mitmdump boots, so ca_cert_pem() read it too early and launch died with
'gateway CA cert not available'. It now polls (up to 30s) until mitmproxy has
generated it. Surfaced running the docker backend locally on a cold gateway.

The cut-over dropped compose (whose `build:` rebuilt the sidecar image on
every up), and DockerGateway.ensure_built was build-if-missing — so a change
to the gateway's flat sources (egress addon / git-http / policy_resolver /
supervise) left a STALE image silently running the old single-tenant daemons
(this bit e2e validation). ensure_built now always `docker build`s
(cache-aware: a cache check when nothing changed, a real rebuild when sources
moved), matching the old compose behavior. BOT_BOTTLE_NO_CACHE forces a full
rebuild (parity with #354's `start --no-cache`).

Rewire DockerBottleBackend.launch to the consolidated model, replacing the
per-bottle sidecar bundle. VALIDATED END-TO-END on real docker:
test_sandbox_escape passes all 5 attacks (egress DLP + git-gate gitleaks)
through the shared gateway.
launch now:
- mints git-gate dynamic keys (if any), then launch_consolidated() to
register the bottle + provision its git-gate state into the gateway and
get the agent's attach context (pinned source IP, gateway address);
- installs the SHARED gateway CA (gateway.ca_cert_pem) into the agent;
- renders the agent-only consolidated compose on the gateway network at the
pinned IP, proxied through the gateway;
- points the agent's git-gate insteadOf (http://<gw>:9420) and supervise
MCP (http://<gw>:9100) at the gateway (DockerBottlePlan.agent_git_gate_url
/ agent_supervise_url);
- teardown = compose down + teardown_consolidated (dereg + deprovision).
Dropped the per-bottle networks, per-bottle egress CA, and bundle service.
Fixes surfaced by the real e2e (couldn't be caught by unit mocks):
- provision_git_gate installs the bottle-agnostic pre-receive/access hooks
into the gateway (were cp'd per-bundle before);
- source-IP allocation reads the *actual* container IPs on the network
(gateway + orchestrator + agents), not just gateway + registry — the
orchestrator container sits on the network and was colliding.
Unit tests for the old bundle launch rewritten against the new collaborators.
NOTE for reviewers: the gateway/bundle image (bot-bottle-sidecars) must be
rebuilt when its flat sources change — `ensure_built` only builds-if-missing,
so a stale image silently runs the OLD single-tenant daemons. A content-hash
/ --rebuild path is a follow-up.

Real-on-host testing surfaced two issues the unit-mocked slices couldn't:
1. The host (NixOS) firewall DROPS container->host traffic, so a host-process
orchestrator is unreachable from the gateway container. Fix: run the
orchestrator AS a container on the shared gateway network (PRD 0070's
"virtualize the orchestrator") — the gateway reaches it by container name
over docker DNS (container<->container, no firewall), and the host CLI
reaches it via a published loopback port.
2. The control plane crashed the connection on a dispatch error (e.g. a
broker failure) instead of returning 500.
Changes:
- lifecycle: OrchestratorProcess (host process) -> OrchestratorService
(containers). Runs the control plane in the bundle image with the repo
bind-mounted (orchestrator is stdlib-only), register-only stub broker so it
needs NO docker socket (the backend launches agents; the host manages both
containers). Registry DB persists via a host-root mount. ensure_running is
an idempotent singleton over both containers.
- gateway: BOT_BOTTLE_ORCHESTRATOR_URL is now the orchestrator's *by-name*
URL on the shared network (dropped the host.docker.internal hack).
- control_plane: _serve wraps dispatch — a failure returns 500, never crashes
the connection.
- OrchestratorProcess default broker -> stub (register-only) for docker.
Validated live end-to-end: both containers up, gateway->orchestrator by name
OK, register -> resolve-by-source-IP returns the bottle's policy from inside
the gateway.

The per-bottle model rendered a compose project with the agent + a sidecar
bundle on two per-bottle networks. Consolidated has no sidecars — one shared
gateway serves everyone — so this renders JUST the agent, attached to the
external shared gateway network at the orchestrator-allocated pinned IP, and
pointed at the gateway's address for egress.
- consolidated_agent_compose(plan, *, gateway_ip, source_ip, network):
agent service only; networks {<gateway>: {ipv4_address: source_ip}} on the
external gateway network; HTTPS_PROXY -> http://<gateway_ip>:9099; NO_PROXY
includes the gateway address so git-http + supervise (also on the gateway)
bypass the proxy and are reached directly. No depends_on/sidecars.
- Pure (takes the launch-time LaunchContext values), so it's unit-testable
without docker.

The consolidated gateway TLS-intercepts every bottle, so all agents must
trust ONE CA. Rather than host-generate + mount a CA, let the gateway's own
mitmproxy generate its CA into a persistent named volume and extract the
cert for agents — no host openssl, keeps gateway.py lean.
- DockerGateway mounts GATEWAY_CA_VOLUME at /home/mitmproxy/.mitmproxy so the
self-generated CA survives container recreation (it must not rotate, or
already-launched agents would stop trusting the gateway).
- ca_cert_pem(): read the CA cert (PEM) out of the running gateway
(docker exec cat mitmproxy-ca-cert.pem) — the agent installs this into its
trust store to accept the gateway's bumped certs.

Composes the orchestrator primitives into the register/teardown sequence
that replaces the per-bottle bundle:
launch_consolidated(egress_plan, git_gate_plan): ensure orchestrator +
gateway up -> read the gateway network's subnet + the gateway's own
address -> allocate the bottle a pinned source IP (skip the gateway +
live bottles) -> register (egress policy blob + slug metadata) ->
provision its git-gate repos/creds into the gateway. Returns a
LaunchContext (bottle_id, identity_token, source_ip, network, gateway_ip,
orchestrator_url) — everything the agent container needs to attach.
Rolls the registration back if provisioning fails, so no orphan.
teardown_consolidated(bottle_id): deregister + deprovision (idempotent).
The agent `docker run` itself stays the backend's job (provider
provisioning); this owns the orchestrator-facing wiring so the sequence is
unit-testable — collaborators mocked, next_free_ip + registration_inputs run
for real (IP allocation + policy blob asserted end to end).

The consolidated gateway ran on the default bridge; the model needs it on a
dedicated user-defined network that every agent bottle also joins, reaching
the gateway's egress / git-http / supervise ports by its address (no host
port publishing) — and the source IP the gateway attributes by is the
bottle's address on this network.
- GATEWAY_NETWORK = "bot-bottle-gateway"; DockerGateway gains a `network`
param.
- ensure_running now ensures the network exists (idempotent create,
tolerating a concurrent 'already exists') then runs with `--network`.
- Docker picks the subnet; the launcher reads it back (13c source-IP
allocator) to hand each bottle a pinned address.

- list_bottles() / health()
- Unlike the fail-closed data-plane resolver, this is the trusted caller: a

the launch path surfaces failures rather than swallowing them.

The consolidated gateway serves every bottle's repos under /git/<bottle_id>/
(slice 10), so each bottle's bare repos + per-repo credential config must be
provisioned into that namespace. This adds the renderer for that; placing
the creds + running it inside the gateway is the launch-wiring step.
- Extract the credential-wiring `init_repo` shell into a shared
`_git_gate_init_repo_fn(repo_root, creds_dir)` — one source for the
security-sensitive logic. The single-tenant daemon entrypoint is
byte-unchanged (still /git + /git-gate/creds; existing tests green).
- git_gate_render_provision(bottle_id, upstreams): posix-sh that inits ONE
bottle's bare repos under /git/<bottle_id>/ reading creds from
/git-gate/creds/<bottle_id>/. Init-only (no `git daemon` — the shared
gateway already serves). Isolating each bottle's repo root + creds dir by
id is what keeps one bottle's push credentials out of another's repos.
- bottle_id is embedded unquoted in the script, so it's restricted to a
shell/path-safe alphabet (registry ids are token_hex; defense in depth).

Bridges the per-bottle `prepare` output to the consolidated registry:
`registration_inputs(plan)` turns a prepared egress plan into the
backend-neutral inputs `Orchestrator.launch_bottle` takes.
- egress_policy(plan): the policy blob = the exact routes YAML the
per-bottle sidecar read from a file; the multi-tenant gateway's
PolicyResolver now fetches it from the registry per request instead.
Same egress_render_routes, so a bottle's allow-list is byte-identical
moving onto the shared gateway.
- RegistrationInputs bundles policy + metadata; metadata carries the human
slug so the shared registry can map a minted bottle id back to a name
(console / supervise display).
Host-side glue (imports bot_bottle.egress) used by the launch path — not
the lean orchestrator control-plane process. Not yet wired into launch
(that's 13c/13d), consistent with the slice-6/10 pattern of landing the
primitive before the cut-over.
Key test: the policy round-trips through load_config back to the same
routes + log level — the resolver-served policy reconstructs the per-bottle
egress config exactly.

First sub-slice of docker launch integration: the foundation the CLI needs
to ensure exactly one orchestrator control plane + shared gateway is up
before registering/launching bottles. Does NOT touch the real launch path
yet — it's the lifecycle primitive the cut-over slices build on.
- OrchestratorProcess.ensure_running(): idempotent singleton — returns the
control-plane URL if a healthy one already answers /health, else spawns
`python -m bot_bottle.orchestrator --broker docker --gateway` detached
(start_new_session, output tee'd to <root>/orchestrator.log) and polls
/health until healthy or timeout (OrchestratorStartError).
- The control-plane port is the singleton key: a second orchestrator can't
bind it, so a stray double-start fails fast rather than forking a rival.
- Host-process (not container) per the PRD's dev-harness sequencing — it
already has the host user's docker access to broker launches; the
data-plane gateway it manages is the container.

Finishes the supervise data-plane writers for the shared gateway. Both
still keyed off a single SUPERVISE_BOTTLE_SLUG env; now each proposal is
attributed to the calling bottle, keeping slices 10/11's per-bottle model.
- git_http_backend: in consolidated mode stamp SUPERVISE_BOTTLE_SLUG=
<bottle_id> into the CGI env. The gitleaks-allow pre-receive hook runs as
a child of the `git http-backend` we spawn, so it inherits the stamp and
queues under the right bottle — no change to the (fragile) embedded hook.
The bottle id is the namespaced root's final component (slice 10), the
same key egress uses. Single-tenant leaves the container-stamped slug.
- supervise_server: resolve the proposal slug per request by source IP when
BOT_BOTTLE_ORCHESTRATOR_URL is set (`_attributed_config`), fail-closed —
an unattributed / unreachable source raises rather than queue under the
wrong or empty slug. `serve`/`main` build + attach the resolver and make
the env slug optional in consolidated mode. Single-tenant unchanged.
Tests: a real git push proving the slug reaches the hook's env; the
supervise attribution matrix (single-tenant slug kept, source-IP bottle
bound, unattributed + resolver-error fail closed).
Remaining supervise gap (noted): websocket DLP still self.config-only.

Consolidated egress ran every bottle through one process but keyed the
supervise proposal queue off a single SUPERVISE_BOTTLE_SLUG env and kept
one *global* DLP safelist — so in the shared gateway an operator's token
approval for bottle A would (a) be attributed to the wrong bottle and
(b) leak into bottle B's DLP scan (A's approved secret passes B's egress).
This slice keys both per bottle, resolved by source IP.
- policy_resolver: add `resolve_policy_and_bottle_id` — policy + bottle id
in one `/resolve`, so egress keys routing *and* the supervise
queue/safelist from a single round-trip. Fail-closed (403 -> (None,None)).
- egress_addon_core: add `resolve_client_context` (+ `ContextResolverLike`)
returning `(Config, bottle_id)`, sharing the fail-closed parse with
`resolve_client_config` via `_config_from_policy`.
- egress_addon: `_active_config` -> `_resolve_flow` returns `(Config, slug)`;
`safe_tokens` set -> per-bottle `_safe_tokens_for(slug)`; the token-allow
write/await/archive + the approved-token add all use the resolved slug.
Single-tenant (no resolver) unchanged — slug = the env SUPERVISE_BOTTLE_SLUG.
New tests cover the resolver, the fail-closed context matrix, and the
cross-tenant isolation (an approval lands only in the calling bottle's
safelist; the proposal is keyed by the source-IP-attributed bottle;
unattributed IPs can't supervise).
Out of scope (noted): the git-gate gitleaks-allow hook + supervise_server
agent-proposal paths, and websocket DLP (still self.config-only, inert in
consolidated mode) — follow-up slices.

(structural, `resolve_bottle_id` only) — fixes the pyright errors from

egress_addon_core.PolicyResolverLike.
- Rename `_project_root`/`project_root`/`resolve_repo_root`/
`DEFAULT_PROJECT_ROOT` -> `_sandbox_root`/`sandbox_root`/
`resolve_sandbox_root`/`DEFAULT_REPO_ROOT`: "sandbox" names the per-tenant
scope; "project" was too amorphous. `GIT_PROJECT_ROOT` keeps git's own
env-var name.
- Note the single-tenant path is transitional (stripped once every backend
runs the consolidated gateway).
- policy_resolver: document that the optional identity token is
transitional — the consolidated end state requires it (flips at the

First slice of git-gate consolidation: make the smart-HTTP git backend
serve every bottle from one process, selecting each request's repo root by
the calling bottle's source IP — the same attribution invariant + resolver
the multi-tenant egress addon uses. `git daemon` can't source-IP-route per
connection, so the consolidated gateway serves git-gate over this HTTP
backend (the transport firecracker/macOS already use); wiring the docker
path onto it lands with the launch-integration slice.
- policy_resolver: factor out `_post_resolve`; add `resolve_bottle_id`
(source IP -> bottle id, same fail-closed 403->None contract as
`resolve`) — the git-gate has no policy blob to parse, the bottle *is*
the namespace.
- git_http_backend: `resolve_repo_root(resolver, base, source_ip, token)`
— single-tenant passthrough when no resolver; else `<base>/<bottle_id>`,
fail-closed on unattributed / resolver error / namespace escape.
`BOT_BOTTLE_ORCHESTRATOR_URL` (same env as egress) flips the shared
gateway multi-tenant; the identity header is read for attribution and
never forwarded to the CGI. Per-repo creds + hooks scope by repo dir, so
isolating the root per bottle isolates its creds too.
Single-tenant path unchanged (existing real-git-push tests green). New unit
coverage for the resolver + repo-root selection matrix. Full unit suite

The egress addon now selects each request's Config by the calling bottle's
source IP, so one shared sidecar serves every bottle. Opt-in and fail-closed;
single-tenant behaviour is unchanged.
Orchestrator side (source-IP-primary attribution, per the PRD invariant):
* registry: `by_source_ip` (the single active bottle at a source IP —
network-layer attribution); `attribute` now composes it + the token.
* service: `resolve(source_ip, token="")` — with a token, strict
attribution; without, source IP alone.
* control_plane: `POST /resolve`'s identity_token is now OPTIONAL (absent
→ source-IP-only); split cleanly from the token-required `/attribute`.
* policy_resolver: `resolve` token now optional.
Egress side:
* egress_addon_core: `resolve_client_config(resolver, client_ip, token)` —
fetches + parses the client's Config, **fail-closed**: unattributed, a
resolver error, or an unparseable policy all yield deny-all (no routes).
Host-testable; `PolicyResolverLike` Protocol keeps it import-free.
* egress_addon: consolidated mode when `BOT_BOTTLE_ORCHESTRATOR_URL` is
set → `_active_config(flow)` resolves per client IP (reads + strips the
`x-bot-bottle-identity` header); `request()` uses it. Unset → the static
routes file, exactly as before. `PolicyResolver` added to the bundle.
Security note: source-IP-only resolution is safe where the IP is unspoofable
(Firecracker /31 + nft) AND the control plane is reachable only by the
trusted sidecar; the identity token, when the agent injects it, strengthens
it on weaker backends.
Scope note: the egress data plane is now multi-tenant. Remaining to be fully
live: the network topology routing every bottle's proxy to the one shared
sidecar, git-gate multitenancy, and agent-side identity-token injection.
Tests: registry by_source_ip; orchestrator resolve (with/without token);
control-plane /resolve token-optional; resolver token-optional;
resolve_client_config fail-closed matrix. All 182 egress tests still pass
(single-tenant unchanged). Full suite green.

Review: the resolver is called rarely enough that a round-trip doesn't
matter, and correctness beats speed — always fetching means a revocation,
policy change, or teardown the orchestrator knows about is honored
immediately instead of lingering for a cache TTL. Remove the TTL cache
(and `invalidate`); `resolve` now hits the orchestrator every call. Noted
in the docstring that any future caching should use orchestrator-driven
invalidation, not a blind TTL.

The data-plane bridge that lets the consolidated sidecar apply each
bottle's policy per request. `PolicyResolver` resolves a client's policy
from the orchestrator's `POST /resolve` keyed on (source_ip, identity
token) and caches it briefly (short TTL) so it isn't a round-trip per
request; `invalidate()` drops an entry on teardown / live reload.
Fail-closed: an unattributed client (orchestrator answers 403) resolves to
None so the caller denies; unreachable / unexpected status raises so the
caller can fail closed too rather than serve stale/empty policy. Stdlib
only and free of bot-bottle imports, so it can be COPYed flat into the
sidecar bundle.
Scope note: this is the sidecar-side *client*. Wiring it into the live
egress mitmproxy addon (select `Config` per client IP in the request path)
and git-gate, plus routing all bottles' egress to the one shared sidecar,
are the remaining data-plane pieces — a heavier change to the sidecar
bundle's adversarial-input code, taken next.
Tests: resolve returns/caches/expires/invalidates; 403 -> None (fail
closed); other HTTP status + unreachable raise; missing policy -> empty;
posts source_ip + identity_token. Full suite green.

The orchestrator side of the multi-tenant consolidated sidecar: hold each
bottle's sidecar policy and serve it by verified source IP, with live
reload. One shared sidecar can now get per-bottle config keyed on who's
calling.
* registry.py — a `policy` column (migration v3, opaque JSON the sidecar
interprets) on BottleRecord; `register(..., policy=)` stores it,
`set_policy(bottle_id, policy)` updates it live, and `attribute` returns
it (the source-IP-keyed resolution).
* service.py — `launch_bottle(..., policy=)` and `set_policy`.
* control_plane.py — `POST /bottles` accepts `policy`; `PUT
/bottles/<id>/policy` live-reloads it; `POST /resolve` returns
{bottle_id, policy} for a verified (source_ip, token) — the per-request
call the multi-tenant sidecar makes; `/attribute` stays identity-only.
Scope note: this is the control-plane / state half. The data-plane half —
the egress mitmproxy addon (and git-gate) selecting allowlist / DLP /
token-injection per client IP by calling `/resolve` — is the next slice
(route agent bottles through the shared sidecar). The orchestrator stays
policy-agnostic: it stores and serves the blob verbatim.
Tests: registry policy store/update/persist; Orchestrator launch-with-policy
+ live set_policy; control-plane resolve returns policy (403 on bad token),
PUT policy updates / 404 / 400. Verified live over HTTP (launch -> resolve
-> PUT reload -> resolve reflects). Full suite green.

Answers "where do we build the consolidated sidecar": nowhere, until now.
* sidecar.py — `Sidecar.ensure_built()` (default no-op) + `DockerSidecar`
now defaults its image to the real bundle (`bot-bottle-sidecars`) and
`ensure_built()` builds it from `Dockerfile.sidecars` when
`docker image inspect` shows it's missing (no-op when present or when no
dockerfile is configured, e.g. a pre-pulled image). `image_exists()`
added.
* service.py — `ensure_sidecar()` now builds then runs.
* __main__.py — `--sidecar` runs the consolidated bundle (build-if-missing).
Scope note: this builds + launches the bundle *container*; making the
running instance functional across bottles needs the per-bottle,
source-IP-keyed multi-tenant config + registration/reload, and routing
agent bottles to it — the next slices (added to PRD 0070's roadmap).
Tests: unit (docker mocked) — image_exists, ensure_built builds when
missing / no-op when present / no-op without a dockerfile / raises on build
failure; ensure_sidecar builds-then-runs; integration (gated, no heavy
build) — image_exists reflects real docker state. Full suite green (only
pre-existing /bin/sleep errors).

Review feedback: don't bury a parallel docker util in the orchestrator.
But reusing backend.docker.util (docker_mod) isn't right either — importing
it runs backend/__init__.py, which eagerly loads all three backends
(docker + firecracker + macos) plus the manifest/egress/git-gate/supervise
framework (~76 modules), so every orchestrator import would drag the whole
backend layer in.
Compromise: promote the helper to a top-level, framework-free
bot_bottle/docker_cmd.py (single stdlib import), a proper shared home the
orchestrator's docker components use now and backend.docker.util can adopt
later. Verified `import bot_bottle.orchestrator` stays lean (12 modules, no
firecracker/macos backends).

The core consolidation win: one persistent sidecar per host, shared by
every bottle, instead of a sidecar bundle per bottle. Safe to share
because the attribution invariant (source IP + identity token) lets the
sidecar map each request to the right bottle.
* orchestrator/sidecar.py — a backend-neutral `Sidecar` lifecycle
contract (mirrors LaunchBroker) + a `DockerSidecar` impl. The defining
behaviour is idempotent singleton: `ensure_running` starts the instance
if absent and is a no-op if it's already up, so N launches never spawn
N sidecars; `stop` is idempotent.
* orchestrator/dockerutil.py — a shared `run_docker` helper; DockerBroker
now uses it too (DRY with slice 3).
* service.py — the Orchestrator holds an optional `Sidecar`, exposes
`ensure_sidecar()` + `sidecar_status()`.
* control_plane.py — `GET /sidecar` reports it; __main__ gains
`--sidecar-image` and ensures the single sidecar on startup.
Tests: unit (docker mocked) — is_running, ensure idempotent (no-op when up,
starts when absent), failure raises, stop idempotent; Orchestrator sidecar
wiring/status; control-plane /sidecar; integration (gated) — ensure is a
real idempotent singleton (one container after two ensures), stop removes.
Full suite green (only pre-existing /bin/sleep errors); integration
verified locally against real docker.

The first concrete LaunchBroker, proving the orchestrator -> backend seam
on the cheapest backend (the sidecar bundle is already containers):
* orchestrator/docker_broker.py — DockerBroker runs a container on a
verified launch (`docker run --detach --name <bottle> --label ...
<image_ref>`) and removes it on teardown (`docker rm --force`,
idempotent on an already-absent container). The argv is built only from
the request's static ids/flags, so nothing free-form reaches docker;
provenance/schema verification is inherited from LaunchBroker.submit.
* __main__.py gains `--broker {stub,docker}` so the harness can drive real
containers.
Slice 3 launches a single container from image_ref (the seam); the full
agent + sidecar bundle is a later slice.
Tests: unit (docker mocked) — argv from static fields, launch/teardown call
the right commands, missing-image and docker-failure raise, teardown
idempotent on missing, forged token never touches docker; integration
(gated on a reachable daemon) — launch creates a real container, teardown
removes it. Full suite green (only pre-existing /bin/sleep errors);
integration verified locally against real docker.

Second slice of PRD 0070, still a backend-neutral dev-harness:
* orchestrator/broker.py — the launch-broker contract. A LaunchRequest is
structured (static ids/flags only — bottle id, pool slot, a
content-addressed image_ref; never a path/argv) and signed as a compact
HS256 JWT so the broker verifies PROVENANCE before acting: a compromised
co-located component can't forge a launch without the shared secret.
verify_request is fail-closed (bad sig / malformed / off-schema -> raise).
Stdlib only (no runtime deps). Ships a StubBroker that records verified
requests for the harness/tests.
* orchestrator/service.py — the Orchestrator: owns the registry and brokers
the lifecycle. launch_bottle mints the bottle + sends a signed launch,
rolling the registry entry back if the launch fails (no orphans);
teardown_bottle brokers teardown then deregisters; attribute delegates.
* control_plane.py — POST /bottles now launches, DELETE tears down (both go
through the Orchestrator + broker). dispatch/server take an Orchestrator.
* __main__.py wires an ephemeral secret + StubBroker for the harness.
Tests: broker sign/verify round-trip, tamper/wrong-secret/malformed/off-schema
rejection, StubBroker fail-closed; Orchestrator launch->registry->attribute,
teardown, rollback-on-broker-failure; control-plane updated for launch/teardown.
Full suite green (only the pre-existing /bin/sleep errors); harness does
launch -> attribute -> teardown over HTTP.

paths is the single home now, so stop re-exporting the path helpers from
supervise: remove host_db_path from supervise's imports + __all__ (it was
re-export-only) and drop bot_bottle_root from __all__ (kept as an import,
still used by audit_dir). supervise_types was already clean. Repoint the
last readers (test_supervise imports host_db_path from paths;
test_supervise_edge calls paths.bot_bottle_root) and refresh the doc

Create bot_bottle/paths.py as the canonical home for the app-root path
helpers (bot_bottle_root, host_db_path, HOST_DB_FILENAME) — foundational,
not supervise- or db-specific. `bot_bottle_root()` now honours a
BOT_BOTTLE_ROOT env override.
Repoint every consumer (supervise, supervise_types, db_store, queue_store,
audit_store, store_manager, bottle_state, cli/supervise, docker/cleanup,
orchestrator/registry) at paths; remove the definitions (and supervise's
duplicate host_db_path) and the now-dead `import sys`. Add paths.py to the
sidecar bundle (Dockerfile.sidecars) for the flat-import copies.
Tests: replace ~12 files' monkeypatching of supervise.bot_bottle_root (and
the flat/pkg/supervise_types triple-patch dance) with a single
`use_bottle_root()` helper that sets BOT_BOTTLE_ROOT — every module and
flat/package copy reads the same env var, so one override covers them all.

host_db_path is shared DB infrastructure, not supervise-specific, so its
canonical home is db_store (alongside DbStore). It resolves bot_bottle_root
from supervise_types lazily inside the function — no load-time cycle, and a
monkey-patch of supervise_types.bot_bottle_root still propagates.
supervise_types re-exports both names for the historical import path
(queue_store/audit_store unchanged); the orchestrator registry now imports
from db_store. Drops the now-unused `import sys` from supervise_types.

Per review: use one shared bot-bottle.db for all runtime state including
the registry (DbStore namespaces by schema_key), so it's one queryable
file for backup/console. default_db_path() -> host_db_path(). Drop the
unilateral WAL flip — WAL on the shared DB affects supervise/audit and is
finicky over guest shares, so it's a deliberate future change; keep a
busy_timeout for lock contention.
PRD State section updated: integrity now by SOLE ownership (only the
orchestrator opens bot-bottle.db; data plane + console reach state via the
control-plane RPC, never a file handle) rather than ro/rw mount-splitting,
which one shared file can't do. Notes the transitional caveat that the
supervise sidecar currently rw-mounts bot-bottle.db.

First implementation slice of PRD 0070, the backend-neutral consolidation
core as a plain-process dev-harness (no VM packaging yet):
* orchestrator/registry.py — SQLite (WAL) runtime-state store on the
existing DbStore/TableMigrations base. Live bottle registry keyed by
source IP + per-bottle identity token, with fail-closed attribution:
a request resolves to a bottle only when its source IP AND identity
token both match exactly one active record (unknown/ambiguous IP,
empty token, or token mismatch all deny). Tokens are 256-bit urandom.
* orchestrator/control_plane.py — the HTTP control plane (the universal
transport chosen in 0070): register / deregister / list / attribute /
health. Routing is a pure dispatch() so it is socket-free testable;
Handler/ControlPlaneServer/make_server are a thin stdlib adapter.
register/deregister are the live-reload path; listing redacts tokens.
* orchestrator/__main__.py — `python -m bot_bottle.orchestrator` harness.
Launch/teardown, the launch broker, and the egress/git/supervise data
plane come in later slices. 24 unit tests (attribution matrix, persistence,
dispatch, one real-socket round-trip).

The pool params (size, IP base, iface prefix, nft table) were triplicated
— hardcoded in netpool.py, scripts/firecracker-netpool.sh, and
nix/firecracker-netpool.nix — plus the IP math (3x) and the nft ruleset
(2x). Nothing enforced agreement; changing the base (ce3fad9, off CGNAT)
forced a coordinated three-file edit, and a missed one would silently
provision a range the launcher doesn't expect.
Collapse to one source of truth:
* netpool.defaults.env — a plain KEY=VALUE file (bash-sourceable,
systemd EnvironmentFile-compatible, Python- and Nix-parseable) holding
the four defaults. A BOT_BOTTLE_FC_* env var still overrides any key.
* netpool.py reads it for the Python defaults (missing file = hard
error, not confusing empty defaults).
* the shell script falls back to it (no literal `:-8` / `10.243.0.0`),
and its `up` is now non-destructive/idempotent (only creates a
missing TAP), so re-running never cuts a live VM.
* the Nix module readFile-parses it for its option defaults and
delegates bring-up to the SAME shell script (dropping its duplicate
IP math, nft ruleset, and TAP loop) — passing every value as
Environment= so the store-detached script never needs the file.
Net: defaults 3x -> 1x, nft ruleset 2x -> 1x, TAP loop 2x -> 1x. The one
remaining IP-math dup (Python launch-addressing vs bash bring-up) is
justified — different runtimes. Tests now guard the invariant (Python
reads the shared file; the script/module hold no literals) instead of
pinning duplicated strings.

The control SSH logs in as root, so the agent (dropped to node via
runuser) inherited cwd=/root. That was harmless while the rootless
rootfs left /root node-owned, but the dropbear fix (chown /root →
root:root 0700) made /root unreadable to node — so the agent's cwd was
inaccessible, breaking Node's process.cwd(), Claude Code's shell-snapshot
machinery, and `/doctor` (which reported /root/.claude EACCES and failed
every Bash command).
Run the agent from its workdir (default /home/node) via `env --chdir`.
Not a `sh -c 'cd … && exec "$@"'` wrapper: ssh space-joins everything
after the host into one string for the guest shell, so the quoted script
+ $@ get re-split and mangled (it exec'd the $0 placeholder → exit 127).
`env --chdir=DIR …` is all simple words, so it survives the join.
Verified end-to-end: a real headless claude bottle now runs its Bash tool
and exits 0 (was EACCES/127 before).

Make the network pool a persistent, distro-uniform resource instead of a
non-persistent per-distro shell command. systemd is the common
denominator across Debian/Ubuntu/Fedora/RHEL/Arch/… (and NixOS), so
`backend setup` on any systemd host now installs one bot-bottle-owned
oneshot unit (bot-bottle-firecracker-netpool.service): params pinned via
Environment= (so it doesn't depend on $SUDO_USER at boot), ExecStart/Stop
delegating to the bundled bring-up script (single source of logic).
- render_systemd_unit() in netpool.py (derived from the same constants
as the shell script + nix module).
- backend setup: install + enable the unit directly when run as root,
else print a self-contained copy-paste block. NixOS keeps its
declarative module (which produces the same-named unit); non-systemd
hosts fall back to the raw imperative script.
- backend teardown: symmetric — disable + remove the unit.
- backend status: report the unit's active/inactive state so you can
tell a persistent install from an imperative one.
Net: one install path (`backend setup`), persistent, identical across
distros; per-distro variance shrinks to installing nft + iproute2.

First real end-to-end launch (there was no firecracker integration test)
surfaced three bugs in the control/provision path, all now verified fixed
by tests/integration/test_firecracker_launch:
1. Guest SSH rejected the correct key. The rootless rootfs build
(`docker export | tar` as a non-root user) can't preserve uid 0, so
every path — including /root — is owned by the build uid (node in
guest). dropbear refuses root's authorized_keys when /root isn't
root-owned, so auth fell back to password → denied. bb-init now
`chown -R 0:0 /root`.
2. The SSH client (newer OpenSSH) didn't reliably present the -i key
against the operator's ~/.ssh config; add `IdentitiesOnly=yes` to
ssh_base_argv so only the per-bottle key is offered.
3. cp_in double-wrapped the remote command as `sh -c <remote>`, but ssh
space-joins everything after the host into one string for the guest
shell, collapsing `sh -c mkdir -p X && …` to `mkdir` with no operand
("missing operand"). Pass the command as a single arg and let the
guest login shell run it (stdin still carries the tar).
Also stop discarding dropbear's stderr (`-E` now reaches the host-side
console.log) so future guest-auth issues are debuggable.

`status()` hard-failed when it couldn't confirm the nft table, but listing
nftables usually needs root — so an unprivileged `backend status` reported
"not ready" even with the pool fully up, making it useless as a launch
gate (and skipping the firecracker integration test on a set-up host).
Base readiness on what the launch preflight actually hard-requires: the
TAP pool present (unprivileged, authoritative) + no range overlap. Report
the nft table state (present / unverified / not-confirmable-unprivileged)
but don't let it flip readiness — the post-boot isolation probe is the
authoritative isolation check, same as the preflight's deferral.

The module used `networking.nftables.tables.*` (which forces
`networking.nftables.enable = true`, flipping the host firewall backend)
and `systemd.network.enable` (handing interfaces to systemd-networkd) —
disruptive on an iptables + Docker daily driver.
Rewrite it to a single systemd oneshot that brings the pool up: idempotent
`ip tuntap` for the TAPs + `nft -f` for the independent `inet bot_bottle_fc`
table (its own hooks at priority -10), with ExecStop teardown. Same as the
imperative script, but declarative. It touches neither the firewall backend
nor networkd, so it coexists with iptables/Docker/ufw/firewalld. Verified
through the NixOS module system (service present, firewall untouched).
Drop the now-redundant `render_nixos_module()` paste generator (the module
is a real importable file) and point `backend setup` at importing it (flake
output or the file path), noting it's non-invasive.

Add abstract `setup()`/`status()` classmethods to BottleBackend (same
per-host, no-instance shape as is_available) so host provisioning is
part of the backend contract, not a per-backend command. Replace the
`./cli.py firecracker {setup,status}` command with a generic
`./cli.py backend {setup,status} [--backend=NAME]` that resolves a
backend (flag / $BOT_BOTTLE_BACKEND / host default) and dispatches —
swapping backends is just a different --backend.
Implementations:
- firecracker: moved out of cli/ into backend/firecracker/setup.py
(network pool module/script + range-overlap check), unchanged output.
- docker: new backend/docker/setup.py — reports docker on PATH, daemon
reachability, and gVisor runsc; setup notes no privileged pool is
needed. Minimal placeholder; richer version tracked in #345.
- macos-container: new setup.py — container CLI + system-service checks.
Also retarget the launch-preflight / isolation-probe pointers to the new
command. New test_cli_backend covers dispatch + docker setup/status.

The default TAP-pool base was 100.64.0.0/10 (RFC-6598 CGNAT) — chosen to
dodge RFC-1918, but that's exactly the range Tailscale assigns node
addresses from, so on a Tailscale host it's the worst pick. Move the
default to 10.243.0.0/16, an obscure RFC-1918 block that steers clear of
docker/libvirt/k8s/LAN and Tailscale.
No default is collision-proof, so add netpool.overlapping_routes(): it
parses `ip -json route show table all` and flags any route intersecting
the pool range (excluding our own bbfc* TAPs and the default route). The
launch preflight warns on overlap; `backend status` reports it.
Distribute the NixOS host setup as a flake module instead of a
copy-pasted blob: nix/firecracker-netpool.nix computes the taps / nft
table from typed options (poolSize, ipBase, ifacePrefix, owner) with a
/31-alignment assertion, and flake.nix exposes it as
nixosModules.firecracker-netpool. Defaults mirror the backend constants;
writeEnvFile emits the matching BOT_BOTTLE_FC_* so the host pool and the
launcher can't drift.

Delete the smolmachines backend (the whole bot_bottle/backend/smolmachines
package and its tests). It had fatal Linux issues (TSI networking under
sustained use, exec-channel contention, no SIGWINCH) and is superseded by
the Firecracker backend (issue #342).
Backend selection now:
- default is macos-container on macOS, firecracker on KVM-capable Linux
hosts, and docker as the last resort (was smolmachines).
- firecracker is selected on a KVM host even when the `firecracker`
binary isn't installed, so start routes through its preflight and
prints an install pointer (same UX as require_container), instead of
silently falling back. Split is_host_capable() (Linux + KVM) out of
is_available() (adds the binary check) to drive this.
Retarget the cross-backend tests (parity, print-parity, prepare,
workspace, freezer, selection) from smolmachines to firecracker rather
than dropping the coverage. Remove docker.util.image_id/save, which only
smolmachines used. Update README/AGENTS/example bottles and stale
comments; historical docs/prds are left as a point-in-time record.

Adds a Firecracker-based backend for Linux, providing mature KVM-based
microVM isolation to replace smolmachines/libkrun (issue #342, closes
the dead-end tracked in #332).
Architecture:
- Guest control over SSH (dropbear injected into the rootfs) on a
point-to-point TAP link. `ssh -t` forwards SIGWINCH natively, so no
resize bridge is needed.
- Networking: a one-time, root-provisioned pool of user-owned TAP
devices (no shared bridge → no docker0/virbr0/cni0 collisions) plus a
dedicated `table inet bot_bottle_fc` nftables table (independent of
Docker/ufw/firewalld rules). `./cli.py firecracker setup` prints the
host-appropriate config (NixOS module or sudo script).
- Rootfs: `docker export` → ext4 via `mke2fs -d` (rootless, no mount),
cached by image digest; per-bottle SSH pubkey + IP passed via the
kernel cmdline.
- Sidecar: reuses the Docker bundle, published on the slot's host TAP IP.
- Fail-closed isolation: TAP pool verified at preflight; the egress
boundary is proven empirically post-boot (before the agent runs) by a
canary probe — the VM must fail to reach the host directly, or launch
is refused.
Linux hosts with Firecracker + KVM now default to this backend;
macOS stays on macos-container.
Not yet validated end-to-end on live hardware (requires the one-time
network pool). Unit tests + pyright pass.

DX improvement: find_repo_bottle_file() is called before the save
prompt so the user sees exactly which file will be updated:
Save host_key for 'myrepo' to /home/.../bottles/dev.md? [y/N]
If no bottle file is found the prompt is skipped and a clear message
explains that the key is session-only.
Also:
- Use find_repo_bottle_file() inside find_and_update_bottle_file()
instead of duplicating the scan logic
- Rename all module-level helpers to public names (no underscore prefix)
since they are imported and tested externally
The regex-based _insert_host_key_in_frontmatter had a bug: child_indent
was overwritten on every line with indent > repo_indent (including
grandchildren), so host_key landed inside the key: block instead of at
the repo level.
Replace with a clean parse → mutate → re-serialize approach:
- Add serialize_yaml_subset() to yaml_subset.py (block-style, 2-space
indent, round-trips through parse_yaml_subset)
- Replace _insert_host_key_in_frontmatter + _update_frontmatter_in_file
with _add_host_key_to_frontmatter that parses the frontmatter dict,
sets fm["git-gate"]["repos"][name]["host_key"], and re-serializes
- _find_and_update_bottle_file simplified to read file → delegate to
_add_host_key_to_frontmatter → write if changed
Servers that don't offer ed25519 (ecdsa-only or rsa-only gitea
instances) would raise "ssh-keyscan returned no ed25519 key" because
`-t ed25519` produced no output.
Remove the `-t ed25519` restriction: ssh-keyscan now returns all
supported key types and the function picks the best available via
_KEY_TYPE_PREFERENCE (ed25519 > ecdsa > rsa > first).
Also adds four new fetch_host_key tests covering multi-type preference
logic and updates the stale "no ed25519 key" assertion.
