Add PRESENTATION.md Slide 11 enumerating the five core-HA seams (from
ARCHITECTURE.md §12) and the no-monkey-patching discipline. Update §12 +
the slide to include the inverse `async_unregister_remote_platform` hook
that the crash-recovery plan added alongside `async_register_remote_platform`.

Replace the three drifted client coercers — event_mirror._to_json_safe
(raw set order), entity_bridge._serialise (sorted sets via _iter), and
entry_runner._json_safe — with a single hass_client._json.json_safe built
on HA's json_encoder_default (the as_dict/set/enum-aware single source of
truth), plus a str() fallback so best-effort event data still degrades a
single odd field to a string instead of raising in the bus callback.
entry_runner keeps its empty-result dict guard and delegates the coercion;
the capabilities hash stays stable (compared within one process, so raw
list(set) order suffices). Drops the now-unused Iterable/json_bytes/
json_loads imports. Adds tests/test_json.py round-tripping sets, enums,
as_dict objects, datetimes, the str() fallback, and non-str keys.

Channel.__init__ / from_transport no longer default `codec` to JsonCodec —
it is now a required keyword. Every production construction site already
passes ProtobufCodec; a forgotten codec is now a construction-time error
instead of silently speaking JSON at a protobuf peer.
JsonCodec leaves the production channel.py (both mirrors) and moves to each
side's test helpers: tests/components/sandbox/_helpers.py (HA) and
hass_client/testing/_jsoncodec.py (client). Channel-core tests import it
from there; the two channel.py mirrors stay byte-identical. The now-unused
`import json` is dropped from channel.py and the protocol.py docstring is
updated for the required codec + relocated JSON codec.

Remove the callerless raise_not_proxied helper (zero callers since the
query RPCs landed), its __all__ entry, and the now-unused NoReturn /
HomeAssistantError imports.
Remove the vestigial `if old_state is not None and entity_id not in
self._pending: pass` no-op block in the client entity_bridge — control
fell through it unchanged — and the now-dead old_state assignment.

Add a `_features_flag: type[IntFlag] | None` class-attr hook on
SandboxProxyEntity and a `_coerce_supported_features` helper that wraps
`description.supported_features` in the domain's IntFlag once, used by both
`__init__` and `sandbox_update_description`. Replace the 17 identical
~10-line `__init__` overrides (light, fan, lock, cover, climate,
media_player, notify, …) with a single `_features_flag = <Domain>EntityFeature`
line each, dropping the now-unused TYPE_CHECKING imports.
The four @final mangled-attribute `sandbox_apply_state` overrides
(button, event, notify, scene) are untouched.

Make channel.py byte-identical across both mirrors (it already matched
modulo docstrings/comments/log capitalization; codec_protobuf.py and
messages.py were already identical). Add check_mirror_drift.sh asserting
all three pairs are byte-identical, wired as a regular prek hook that
fires whenever either copy of a mirrored file changes. Document the
edit-both rule in-file next to the guard.
This retires the ad-hoc 'apply to both mirrors' discipline the earlier
review-follow-up plans had to carry by hand.

Plan-4 commits accidentally added generated sandbox store fixtures
(tests/testing_config/.storage/sandbox/built-in/*) written by the test
runtime. origin tracks none of testing_config/.storage; the prior
c3f0abc53c 'stop tracking generated test .storage' untracked a sibling
file but added no ignore rule, so it recurred. Remove these and add a
targeted .gitignore so the test store dir can't be re-committed.

Discovery flows feed the proxy non-JSON objects — a *ServiceInfo dataclass
(IPv4Address fields, sets) as the first-step user_input and a DiscoveryKey in
context — which dict_to_struct couldn't hold, crashing the flow unhandled
(the except only caught channel errors). The router routes discovery-sourced
flows to the sandbox with no source filter, so this was reachable.
Main side: _to_jsonable walks context + first-step payload into Struct-safe
primitives (dataclasses -> field dicts, IPs -> str, sets -> lists) before
dict_to_struct. Broadened the except to abort cleanly on any unmapped payload
that still trips the marshaller.
Sandbox side: _rehydrate_discovery rebuilds the real DiscoveryKey + the
source's BaseServiceInfo (zeroconf/homekit, ssdp, dhcp, usb, hassio, mqtt) so
async_step_<source> receives the type it expects. Unmapped sources (bluetooth)
leave a dict; reconstruction failures degrade to the dict with the proxy's
clean abort as the outer backstop.

Two fixes in the flow proxy:
1. MENU support end-to-end. async_show_menu is common and marshals like a
form. Added FlowResult.menu_options (ListValue) + sort to the proto, marshal
it sandbox-side, and re-issue async_show_menu on main. A dict-form menu
(id -> label) crosses as ordered [id, label] pairs so labels survive; a
menu selection is forwarded as the sandbox flow's {"next_step_id": <chosen>}
navigation choice.
2. Leak fix. The unsupported-result-type branch set _terminated=True before
aborting, which made async_remove skip the flow_abort RPC — leaving the
sandbox-side flow in progress and wedging retries on already_in_progress if
it had set a unique_id. The non-terminal result types (external-step,
progress) no longer set _terminated, so async_remove reaps the sandbox flow.
Regenerated proto gencode for both mirrors.

The proxy CREATE_ENTRY path read only data/title/description and called
async_create_entry, which stamps the proxy class defaults VERSION=1 /
MINOR_VERSION=1 / options={}. A sandboxed flow with VERSION>1 lost its
schema version (spurious migration on next setup) and dropped options.
async_create_entry reads self.VERSION/self.MINOR_VERSION off the *instance*
(config_entries.py async_create_entry), so override the proxy instance's
values from the wire result before the call, and plumb options= through.

Records the 7-phase client-runtime + wire-fidelity batch: per-phase
summaries, the messages.py both-mirrors byte-identical note, the Phase 7
no-narrowing decision, the Phase 3 correctness-fix approach + plan-5
writer-queue handoff, tests added, and final green verification.
_handle_shutdown set the shutdown event via call_soon so the reply lands
on the wire first, but call_soon only buys one loop turn — if the reply
write suspended (write-lock contention from unload pushes, drain
backpressure on a large restore_state), run()'s finally closed the channel
and cancelled the in-flight reply task, so main lost restore_state.
Add Channel.drain_inflight(timeout): wait for in-flight inbound handler
tasks (the shutdown reply included) to finish before close, without
cancelling anything. run()'s finally now drains before close(), so the
reply completes its write instead of being cancelled mid-flush.
Write-lock check (Phase 4 bullet 2): _write_lock is a plain mutex held
only across one frame write, so the shutdown reply and the unload-driven
_push_unregister writes serialize — no circular wait, no deadlock.
drain_inflight added to both hand-mirrored channel.py copies. Regression
test stalls the reply's drain and asserts main still receives it (verified
it fails with ChannelClosedError when the drain step is removed).
protobuf.Struct stores all numbers as double, so _value_to_py returned
entry.data ints, service_data ints, and the store envelope's version/
minor_version as floats — breaking socket()/isinstance(int)/range(...).
_value_to_py now coerces whole-number floats back to int
(int(v) if v.is_integer() else v); genuinely fractional values (0.5) keep
their float type. Reviewed every struct_to_dict / listvalue_to_list
consumer (flow/entry data, service_data, target, entity_query args/result,
store data, state attributes, capabilities, event_data, translations) —
none needs a whole-number float to stay float, so the global coercion is
safe; no field narrowing required.
Applied byte-identically to BOTH hand-mirrored copies:
homeassistant/components/sandbox/messages.py
sandbox/hass_client/hass_client/messages.py
(verified identical via diff). The explicit int32 proto fields (version,
minor_version, supported_features on EntrySetup) bypass the Struct and are
unaffected.
A failed async_setup left the rebuilt ConfigEntry in the sandbox's
config_entries (only unload popped it), so main's later retry of the same
entry_id was rejected with 'entry already loaded'. On both failure paths
(async_setup raised / returned False) the entry is now popped before
returning ok=False, so a re-sent entry_setup starts clean.
Sandbox-side half of plan 1's SETUP_RETRY decision: main shipped honest
SETUP_ERROR + manual reload and remains the only retry driver. The
sandbox-side ConfigEntryNotReady timer is deliberately NOT enabled (the
sandbox hass is never async_started).
EntityBridge._register added an approval refcount per registered entity
(approved.add(domain)) but nothing ever decremented it, so a platform
domain stayed approved for the process lifetime — the service/event gate
stayed open for domains with zero owning entities.
Track each entity's contributed domain (_approved_domain) and release it
(_release_approval -> approved.remove) on both unregister paths: the
new_state-is-None removal and the Phase 3 removal-while-pending flush.
Symmetric with the per-entity add; the refcount drops to absent when the
last entity of a domain unregisters. EntryRunner's per-entry
approved.remove(entry.domain) on entry_unload already balances the
per-entry add, so it is unchanged.
_on_state_changed dropped any state_changed while an entity sat in
_pending (register RPC in flight), and the register task pushed only the
snapshot captured at task-creation. A fast second update was lost; a
removal in the window left a ghost proxy on main (the entity wasn't in
_registered yet, so the removal was dropped).
After the register RPC resolves, the task now:
- if a removal raced (new _removed_while_pending flag), unregisters the
entity it just registered, so main keeps no ghost proxy;
- otherwise re-reads hass.states and pushes a state_changed when the live
state differs from the registered snapshot, flushing the coalesced gap.
This is the correctness fix only. Plan 5 (simplification) builds a
single-writer queue on top of the entity push path; when it lands it
should subsume this flush into the queue's ordering guarantees (noted in
code).
SandboxRuntime.run pushed Ready (manager flips to running, router sends
entry_setup), awaited the warm-load store_load, and only then registered
MSG_ENTRY_SETUP et al. An entry_setup arriving in that window hit
ChannelUnknownType -> SETUP_ERROR.
Now: register every inbound handler first, run the (outbound) warm-load
store_load, then push Ready as the last frame. This both removes the
no-handler race and preserves the warm-load-before-entry_setup invariant
(Ready timing still gates entry_setup until the restore cache is warm).
EVENT_SERVICE_REGISTERED fires synchronously while a service is
registered inside async_setup_entry, but EntryRunner only approves the
domain after async_setup returns, so ServiceMirror dropped those early
registrations with a warning and never replayed them.
ApprovedDomains now fires approve-listeners on the first (absent->present)
add; ServiceMirror subscribes async_sync_domain, which re-mirrors every
already-registered service of the freshly-approved domain (skipping any
already in _mirrored). Covers both the entry-runner approve path and the
entity-bridge per-entity approve path.
EventMirror is left as-is: owned events are transient, so a past event
cannot be replayed (noted in plan Phase 1).
All trust-boundary gates this plan proposed shipped (Phases 1-6, none
deferred), so the malicious-sandbox guarantees the architecture asserts now
match enforced reality. Added a one-line 'enforced on main in
bridge.py/channel.py' note for each gate, traceable to code:
* §4 channel read-backpressure shedding (both mirrors)
* §8 register_entity entry ownership + foreign-device-merge refusal
* §8 register_service / fire_event owned-domain gates + core deny-list
* §8 context-cache eviction bound on the resolve path
* §9 store key-length + value/total/key-count quotas
* §11 translation overlay narrowed to requested ∩ returned
No 'Known trust-boundary gaps' subsection is needed — nothing was deferred.
Added a changelog row. README.md/CLAUDE.md make no overstated boundary
claims (only 'isolated subprocesses', accurate), so no softening needed.
One forged-frame test per trust-boundary gate:
* fire_event: core (homeassistant_stop/call_service/state_changed) and
unowned-domain (zha_event/hue_event) events are dropped, never reach the bus.
* register_service: an unowned domain (persistent_notification) is rejected.
* register_entity: a foreign entry_id (entry.sandbox != group) is rejected;
a device_info colliding with a foreign entry's device is refused (no merge).
* translation: a forged foreign domain returned alongside the owned one is
dropped; only the requested ∩ returned survives.
* store_save: an overlong key and an oversized value are rejected; nothing
hits disk.
* context cache: a flood of distinct unknown context_ids stays bounded by
_CONTEXT_CACHE_MAX.
* channel backpressure: over the max_queued cap, inbound calls are shed with
a ChannelOverloaded error and the inflight set stops growing.
make_channel_pair gained max_queued_a/b passthrough for the backpressure test.
Two unbounded-growth vectors closed:
1. Context cache on resolve. _resolve_context minted a fresh Context per
unknown context_id but never enforced _CONTEXT_CACHE_MAX (only
_remember_context did), so a sandbox flooding distinct unknown ids grew
the cache without bound. Factor a single _store_context() helper used by
both paths so the cap + expiry-ordering apply uniformly.
2. Channel read backpressure (BOTH mirrors). The reader create_task'd a
handler per inbound frame; the inflight semaphore caps *running*
handlers but queued tasks — each pinning a decoded payload up to
MAX_FRAME_SIZE — grew without bound under a flood. _dispatch now sheds
over a DEFAULT_MAX_QUEUED cap on inflight handler tasks: inbound calls
are rejected with a ChannelOverloaded error frame, pushes dropped.
Responses are always handled inline above the gate, so backpressure
never starves a reply.
The channel.py edit is applied byte-identically to both hand-mirrored
copies (homeassistant/components/sandbox/channel.py and
sandbox/hass_client/hass_client/channel.py), rebased on top of plan
#1's Channel.close() fix, in this separate commit.
Design note: shed (reject/drop over a bounded cap) rather than block the
reader on the semaphore. Blocking the shared reader would deadlock the
documented nested-call pattern — a handler that issues channel.call() and
awaits its reply through the same reader would stall it once all slots are
held by such handlers (real on the client mirror: a call_service handler
doing a store_save round-trip to main). Shedding bounds memory without
that liveness hazard and stays safe in both mirrors.
_validate_key now caps key length (128, well under NAME_MAX). async_save
caps each value (4 MB) and enforces a per-group dir quota (32 MB total,
256 keys) via _enforce_group_quota before the atomic write, so a
compromised sandbox can no longer exhaust the host disk through the
store-routing channel. Limits are commented, generous-but-finite
constants.
Over-quota writes raise HomeAssistantError → remote-error frame; the
sandbox-side async_store_save already catches ChannelRemoteError and logs
(keeping its in-memory data), so a rejected flush degrades, not crashes.
The provider overlay (_TranslationCache._async_overlay_sandbox_strings)
splices every domain a sandbox returns, narrowed only by the broad
requested components set — so a compromised sandbox could return strings
for a co-requested victim domain (hue, http) and poison its frontend
strings. async_get_translations now keeps only the requested ∩ returned
intersection (domains & strings.keys()), the set this group was actually
asked to resolve, before handing strings to the cache.
_handle_register_entity now requires entry.sandbox == self.group, not
just that the entry_id resolves: a compromised sandbox may only register
entities for entries main routed to *this* group. Without this it could
attach entities and pre-create devices against a victim integration's
config entry.
Also reject a device pre-create that would merge (via shared
identifiers/connections) into a device already owned by a config entry
outside this group — _reject_foreign_device_merge — closing the
device-registry hijack vector. entry.sandbox is set by main at flow
completion, never by the sandbox.
entry_setup/entry_unload are main-initiated (main supplies the entry_id),
and the store server is scoped one-dir-per-channel by construction, so no
further entry_id trust points need gating.
Test entry fixtures across bridge/entity_query/domain_proxies/
crash_recovery/proto_transport updated to tag their entries sandbox="built-in".
_handle_register_service now requires the service domain to be one this
group owns (same main-side _owned_domains() derivation as the fire_event
gate), so a compromised sandbox can no longer squat
persistent_notification.* or any unclaimed domain.service. Unowned
domains are rejected with a HomeAssistantError → remote-error frame; the
existing refuse-to-clobber-an-existing-handler check is kept.
Existing register_service tests updated to own their mock domains via a
MockConfigEntry(sandbox="built-in").
Enforce on main the same <owned_domain>_ rule the sandbox claimed to:
_handle_fire_event now drops any event that is not in the <domain>_
namespace of a domain this group owns, plus a hard deny-list of core
control-plane events (homeassistant_*, call_service, state_changed, ...)
so an owned domain can never alias a core event.
Owned-domain trust is derived purely from main-side state via the new
_owned_domains() helper (entries with entry.sandbox == self.group plus
registered proxy platform domains) — never from a sandbox-supplied
identifier. The helper is the linchpin reused by the register_service
gate in the next phase.
Drops (never raises) on a forged push, so the dispatch loop is unaffected.
Documents all six phases shipped, the /phx:work→intent deviation, the
SETUP_RETRY→SETUP_ERROR fallback (true retry not feasible from the router
seam), the new EntityComponent.async_unregister_remote_platform public
hook, the channel.py both-mirrors note, test coverage, and final
verification (224 + 87 + 30 passed; drift clean; prek clean).

Guards every fix in the cluster:
- test_crash_recovery.py (new): crash→respawn→re-register (Phase 1),
sandbox-dies-availability + recovery (Phase 2), unload-while-down
releases the platform (Phase 4).
- test_manager.py: stop()-during-spawn completes without hang (Phase 3) —
a _PausingProcess lands stop() while _spawn is suspended so
self._process is still None.
- test_channel.py: Channel.close() after EOF still closes the transport
and awaits inflight exactly once, and is idempotent (Phase 5).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Channel.close() early-returned on `if self._closed: return`. But the read
loop's EOF `finally` already sets `_closed=True` (and cancels, never
awaits, inflight tasks), so a close() after EOF returned immediately —
transport.close() and the inflight gather never ran, leaking the stdin
pipe / unix connection every restart cycle. Split "already closed" (set
_closed, fail pending — idempotent) from "teardown not yet done" (close
transport + await inflight, guarded by a new _close_done flag that runs
exactly once regardless of who set _closed first).
channel.py is hand-mirrored — the identical fix is applied to BOTH copies
(homeassistant/components/sandbox/channel.py and
sandbox/hass_client/hass_client/channel.py).
SETUP_RETRY non-retry: the router runs outside ConfigEntry.async_setup,
so the SETUP_RETRY timer (async_call_later) is never armed for a sandbox
entry — a router-set SETUP_RETRY wedged the entry in a retry state that
never fires (and a later async_setup raised OperationNotAllowed). The
ChannelClosedError-during-entry_setup case now reports SETUP_ERROR
honestly (recoverable via manual reload); ARCHITECTURE.md §5 updated and
a router-driven true retry flagged as a follow-up.

router.async_unload_entry returned True without any cleanup when the
sandbox/channel was down, leaking the proxy entities and the
EntityComponent platform registration → a later re-setup hit "has
already been setup!".
Extract a shared _async_unload_main_side helper (delegates to
bridge.async_unload_entry, which now uses the Phase 1 public-hook
teardown) and call it on every exit that should release main-side state:
the sandbox-down early return and a ChannelClosedError mid-unload both
skip the (impossible) remote RPC but still remove the proxies + platform.
A live sandbox that refuses the unload (ChannelRemoteError) still returns
False with the proxies left in place.

Two paths could hang HA shutdown or wedge a sandbox forever:
- stop() spawn-in-progress race: a stop() that landed inside _spawn read
self._process as None, terminated nothing, then awaited the supervisor
forever while the freshly-spawned healthy child ran unsupervised. Fix:
a post-spawn _stopping check in _run_one_{stdio,unix} kills the child
stop() missed, and stop()'s await is bounded with a SIGKILL+cancel
backstop. Terminate logic is extracted into a shared _terminate helper.
- Respawn had no ready-timeout: ready_timeout was only applied in the
first start(). _supervise_until_exit now bounds the ready handshake on
every attempt; a child that opens its channel but never signals ready
is killed and counts against the restart budget instead of leaving the
sandbox 'starting' forever.
Also: ensure_started no longer hands back a 'starting' zombie — it awaits
readiness (bounded) via the new async_wait_until_ready and raises
SandboxFailedError if the in-flight spawn never becomes running.

sandbox_set_available() had zero callers, so a dead sandbox's proxies
kept serving their last state — a crashed integration's light read "on"
forever to automations and the UI.
- Add SandboxBridge.async_mark_all_unavailable() (flips every owned proxy
to unavailable via the existing sandbox_set_available).
- Add a manager on_channel_closed callback fired right after the control
channel is closed on process exit; __init__ wires it to mark the
group's live bridge unavailable. Proxies flip back to available on
respawn through the normal register/state_changed round-trip.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Keystone fix for crash/restart recovery: a respawn used to overwrite
data.bridges with a fresh SandboxBridge but never released the old one's
proxy entities or its EntityComponent platform slots, so the first
register_entity after respawn raised ValueError("… has already been
setup!") and every entity for the entry failed permanently.
- Add the public inverse hook EntityComponent.async_unregister_remote_platform
(mirrors async_register_remote_platform; no private _platforms poke —
the bridge's old SLF001 poke in async_unload_entry is replaced by it).
- Add SandboxBridge.async_teardown() + a shared _async_teardown_entry
helper; async_unload_entry now routes through it.
- __init__: on restart, stash the displaced bridge in
SandboxData.pending_teardown and, when the fresh process goes ready,
tear it down and re-drive entry_setup (async_schedule_reload) for the
group's loaded entries. A new manager on_ready callback is the trigger
(fires on every (re)spawn after MSG_READY); capturing loaded entries
synchronously keeps a first start from being treated as a respawn.

Capture the 2026-06-12 sandbox code review as actionable artifacts:
- plans/plan-review-INDEX.md + five phased fix plans covering every verified
finding — crash/restart recovery, trust-boundary hardening, client-side
races + int->float wire fidelity, config-flow forwarding fidelity, and
simplification/dedup. Index records execution order and a finding->plan
coverage map; plans cross-reference each other by name.
- PRESENTATION.md — a 10-slide intro to the sandbox concept (what data
represents an integration in another instance -> entity/registry/device,
service control, event listening, action forwarding, entity RPC for
query-shaped APIs, then sandboxes as ephemeral one-domain isolates).
The documentation findings from the review were fixed directly (prior commit);
the remaining code findings are planned here, not yet implemented.

Delete OVERVIEW.md — it duplicated ARCHITECTURE.md at a different altitude and
was the source of every doc-vs-doc disagreement found in review (31-vs-32
proxies, SETUP_RETRY vs SETUP_ERROR, classify-at-entry-setup). ARCHITECTURE.md
is now the single architecture reference; its missing "where to look in the
code" map moved in as §15.
Scrub all v1 references from the live docs: the changelog removal line, the
rename row wording, README's "v1 kept for reference" prose, and CLAUDE's
v1-removal paragraph, Iron-Law cautionary tale, and "v1 removal. DONE" bullet.
Fix ARCHITECTURE drift: crash-budget exhaustion is SETUP_ERROR (not
SETUP_RETRY); classify() runs at flow creation only. Rewrite README.md to a
slim entry point (real stdio:// quick-start, no ws://token/RemoteStore),
re-point CLAUDE.md's OVERVIEW links to ARCHITECTURE.md, and correct CLAUDE.md
to list five core-HA surfaces.

Record what shipped per phase (service-path + EntityQuery request/response),
what stays deferred (subscription/push primitive, todo, browse_media
media-source caveat), the deviations (search via async_internal_search_media,

green verification summary lines.

Reflect the shipped request/response query RPCs across the docs: the
server-side query + WS-only mutation entity APIs now answer with real data
(service-path return_response + the generic entity_query RPC), so the
catalogue's status column, ARCHITECTURE §8/§14, OVERVIEW's "still open"
bullet, and the CLAUDE.md follow-up all move from "raises" to "wired". Kept
accurate as still-open: the subscription/push primitive (the */subscribe
one-shot-only rows + todo item-list push) and the media_player.browse_media
media-source caveat.

Round-trip rebuild tests for SearchMedia and Segment (the as_dict /
dataclass-asdict-vs-constructor asymmetry), per-op EntityQuery proxy tests
(media search, release notes, vacuum segments, calendar update/delete) that
assert the rebuilt typed object and the forwarded method + args, and the two
error paths: a sandbox-side ServiceValidationError translating to a
HomeAssistantError on main, and a closed channel degrading to a clean
HomeAssistantError. Client-side coverage for the EntityQuery handler:
method invocation + kwarg passing, unknown entity_id, unknown method, and a
raising method propagating its exception type on the error frame.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Replace the remaining raise_not_proxied stubs with EntityQuery forwards +
typed rebuilds, so every query-shaped entity API now answers with real data:
- media_player.async_search_media -> async_internal_search_media (which
rebuilds the SearchMediaQuery from flat kwargs on the sandbox side, so the
query crosses as plain JSON); rebuilds SearchMedia, reusing the BrowseMedia
helper for its result list.
- update.async_release_notes -> async_release_notes (plain str/None).
- vacuum.async_get_segments -> async_get_segments; rebuilds list[Segment].
- calendar.async_update_event / async_delete_event -> the matching WS-only
entity methods (None result).
The sandbox-side serialisation is the as_dict-aware JSON encoder already
added with the handler, so SearchMedia/BrowseMedia/Segment cross verbatim.
raise_not_proxied is now callerless but kept exported for the still-deferred
subscription/todo-push primitive.

The fire-and-forget call_service channel can command an entity but can't
ask it a server-side question that has no SupportsResponse service to ride.
Add one generic EntityQuery RPC for those, mirroring the call_service path
end to end (proto -> codec registry -> bridge sender + error translation ->
sandbox handler -> proxy helper):
- proto: EntityQuery {sandbox_entity_id, method, args, context_id} and
EntityQueryResult {result} (the return wrapped as {"value": ...} so
scalar/list/None are all representable). Gencode regenerated into both
_pb2 mirrors; drift guard passes.
- MSG_ENTITY_QUERY constant + REGISTRY entry added to both protocol/messages
mirrors.
- SandboxBridge.async_entity_query builds the request, remembers the context
before the id is reduced to a wire value, translates remote/closed errors
through the existing paths, and unwraps {"value": ...}.
- EntryRunner._handle_entity_query resolves the entity on the private hass,
invokes the named method with the decoded kwargs, and serialises the return
through the as_dict-aware JSON encoder; raised HA/voluptuous errors
propagate as channel error frames so main rebuilds the same shape.
- SandboxProxyEntity._entity_query is the proxy-side companion to
_call_service.
No proxy op is wired onto it yet — that is the next phase.

Wire the three query-shaped entity APIs that have a SupportsResponse
service onto the existing call_service + return_response channel, so a
sandboxed entity answers them with real data instead of raising:
- calendar.async_get_events -> calendar.get_events service, rebuilding
list[CalendarEvent] from the response (explicit field mapping, ISO
date/datetime parse — not a **dict splat).
- weather.async_forecast_{daily,hourly,twice_daily} -> weather.get_forecasts
service; Forecast is a plain TypedDict, returned verbatim.
- media_player.async_browse_media -> media_player.browse_media service,
rebuilding the recursive BrowseMedia from its frontend-shaped as_dict.
SandboxProxyEntity._call_service grows a return_response flag that decodes
the CallServiceResult response into a dict. The sandbox-side call_service
handler now runs rich service responses (e.g. a BrowseMedia object keyed by
entity_id) through the as_dict-aware JSON encoder before packing the Struct,
yielding the exact wire shape main rebuilds from.
Caveat documented at the browse_media call site: a sandboxed player's browse
surfaces only its own sources; the media_source tree is empty inside the
sandbox (media_source runs on main). Round-trip rebuild unit tests cover the
as_dict-vs-constructor asymmetry first (plan Risk #2).

Document the unproxied query/subscribe/WS-only entity APIs, their interim
raise behaviour, and the two missing primitives (request/response +
subscription RPC) in docs/query-shaped-rpcs.md. Add the implementation
plan (plan-query-rpc.md): a generic EntityQuery RPC for the service-less
ops + reuse of the existing call_service return_response path for ops
that have a SupportsResponse service. Note the media_player.browse_media
caveat (no media_source tree inside the sandbox). Cross-reference from
ARCHITECTURE/OVERVIEW/CLAUDE.

The server-side query / subscribe / WS-only-mutation entity APIs the
fire-and-forget call_service bridge can't express (calendar listings +
event update/delete, weather forecasts, media browse/search, update
release notes, vacuum segments) previously returned empty/None silently.
Add entity.raise_not_proxied and have those proxy methods raise
HomeAssistantError instead, so the gap fails loudly until a real query
RPC lands.
todo is a special case: its To-do panel reads the sync todo_items
property that also feeds TodoListEntity.state, so it can't be a query at
all. Route it to main via SANDBOX_INCOMPATIBLE_PLATFORMS and drop the
proxy (matching the camera/image precedent).

Both docs now describe the translation-forwarding subsystem in the body,
not just the goal: live pull (sandbox/get_translations RPC + provider
overlay) and the picker catalog hook.
- OVERVIEW: add a Translation forwarding section + "where to look" row +
v1-diff row. Fix pre-existing drift: ALWAYS_MAIN is 24 entries across
three groups (was listed as 6), failed-sandbox setup is SETUP_ERROR
(not SETUP_RETRY), and the manager runs no periodic ping loop.
- ARCHITECTURE: add §11 Translation forwarding (renumber following
sections), list translation.py/catalog.py in §2, and correct the core
touch surface from three to five hooks.

Translation forwarding (live pull-RPC + catalog provider) now puts the
sandboxed integration's translations on main alongside its entities,
services, and events — note it in the OVERVIEW + ARCHITECTURE goals.

Add sandbox/docs/catalog-provider-contract.md describing the display-only
picker catalog hook: the discoverability gap it closes, the
async_register_sandbox_catalog_provider API, and the contract — separate
from the sha-pinned source resolver, name load-bearing, title_translations
optional, no validation, display-only scope, and how it complements the
Phase B live RPC for the cold picker case.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Wire the A1 catalog hook into the two display paths a sandbox-only custom
falls through today:
- async_get_integration_descriptions (loader.py): append catalog
descriptors to the custom integration/helper buckets so the add-
integration picker lists them. On-disk customs carry richer metadata,
so the disk scan wins on a domain collision.
- _async_get_component_strings (helpers/translation.py): when a domain
has no on-disk Integration (IntegrationNotFound on main), take its
"title" from the catalog — a localized title_translations[lang] if
present, otherwise degrading to the descriptor name.
Tests: catalog entry appears in descriptions with picker name + defaults
+ helper-bucket routing; on-disk custom wins a collision; title fallback
uses title_translations and degrades to name when absent.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add a separate, display-only catalog hook so a custom integration whose
code lives only in a sandbox (never on main's disk) can be listed and
named in the add-integration picker without spawning a sandbox.
Core (homeassistant/loader.py) owns the registry because core consumes
it: SandboxIntegrationDescriptor, SandboxCatalogProvider,
DATA_SANDBOX_CATALOG_PROVIDERS, async_register_sandbox_catalog_provider,
async_get_sandbox_catalog. This mirrors the Phase B translation-provider
precedent (hook + consumer co-located in core).
homeassistant/components/sandbox/catalog.py re-exports the hook so HACS
registers through a sandbox namespace parallel to the source resolver —
but the catalog stays deliberately separate from the sha-pinned, security-
critical source resolver: it is eager, enumerable and cosmetic only.
Wired into descriptions + title fallback in A2.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Implement SandboxTranslationProvider and register it into core's translation
hook from async_setup (unregistered on stop). For each requested component it:
- resolves the owning sandbox group — a loaded entry's .sandbox field wins,
else the live SandboxFlowProxy of a brand-new custom's in-progress flow
(new sandbox_group accessor on the proxy);
- carves out built-ins (Integration.is_built_in ⇒ main reads its byte-identical
disk copy, never the wire);
- batches each group's custom domains into one get_translations RPC per
language (5s timeout), and degrades to empty strings on a down/closed/slow
channel so the cache-lock overlay never blocks the frontend.
router.async_unload_entry now invalidates a sandboxed entry's cached
translations, so a reload at a new integration-source ref re-pulls fresh
strings on the next fetch.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add a sandbox-agnostic seam to the translation cache, mirroring the
sandbox.sources source-resolver convention:
- async_register_sandbox_translation_provider(hass, provider): a HassKey-backed
registry with an unregister callback. The provider is awaited inside the
cache load and returns {language: {domain: raw_strings}} for only the domains
it owns.
- _TranslationCache._async_load overlays the provider result onto
translation_by_language_strings after async_get_integrations and before
_build_category_cache, so sandboxed strings flow through the same flatten /
English-fallback / loaded machinery as on-disk strings. A custom sandboxed
domain (IntegrationNotFound on main) thus stops resolving to {}.
- _TranslationCache.async_invalidate + async_invalidate_translations wrapper:
the first eviction API (translations were never unloaded), called by the
sandbox when a custom integration is re-fetched at a new ref.
Core never raises on a provider; degrade-to-empty is the provider's contract.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Register a sandbox/get_translations handler in SandboxRuntime. It loads raw
translation strings for the requested domains from the sandbox's own
filesystem (built-in from the bundled package, custom from the fetched
<config>/custom_components/<domain>) by reusing core's
_async_get_component_strings against the sandbox-private hass — which also
pre-fills 'title' from integration.name. Main cannot run that fallback for a
custom domain because it holds no Integration, so the title must be injected
here. Replies with {language, strings: {domain: raw dict}}.
Tests cover built-in title pass-through, custom title injection, the empty
case, the Struct packing, and the no-flow-runner guard.

Add the sandbox/get_translations message pair to the control-channel proto
and regenerate the checked-in gencode for both no-cross-import mirrors.
Mirror MSG_GET_TRANSLATIONS in both protocol.py files and register the
message pair in both messages.py REGISTRY copies.
Request {language, domains[]}; result {language, strings: {domain: raw
strings.json dict}} — main batches a group's custom domains into one call;
built-in domains never cross the wire.

Rewrote the briefing so it never frames the brief as a file or mentions
the former tempfile handoff: compose it, pipe it straight into the session
(heredoc), claude-screen pastes it as one message. Dropped the file-pipe
example and the "no tempfile dance" aside.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Now that claude-screen pastes multi-line directly, the brief no longer
needs a tempfile + "Read /tmp/X" pointer. Step 1 reads "Compose the brief"
(source it from a heredoc or any scratch file) instead of "Write the
brief"; step 2 shows both heredoc and file pipes. The brief is just stdin,
not a handoff artifact.

Tidy the directory: the 29 per-phase + per-plan landing records
(STATUS-phase-*.md, STATUS-plan-*.md) move out of the sandbox/ root into
sandbox/status/ (git mv, blame preserved). Live current-state docs
(CLAUDE.md, README.md, OVERVIEW.md, FOLLOWUPS.md, architecture.html, the
docker-compose harness comment) now point at status/. Historical records
(the STATUS bodies themselves, plans/*.md, plan.md) keep their original
text by convention.

claude-screen pastes multi-line prompts directly: bracketed-paste markers
keep embedded newlines literal, and the submit \r is sent as a separate
keystroke a beat later (the concatenated \r was what raced the paste and
submitted mid-prompt). Verified live — a 3-line prompt lands as one
message. Doc no longer mentions any file-handoff.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
The single-line file-handoff is now built into claude-screen itself (it
detects a newline in the piped prompt, stashes the brief to a tempfile,
and pastes a pointer). So the doc just pipes the brief straight in; the
manual "write to /tmp + echo a single line" dance is gone.

machine-generated outputs (COMPAT_FULL.md/.csv, COMPAT_LATEST.md, COMPAT.csv,

The registered-service forwarder (_build_service_forwarder._forward) rebuilt its
own pb.CallService request and duplicated the ChannelRemoteError/
ChannelClosedError translation that _raw_call_service already does. With the
batcher gone, _raw_call_service is the single low-level send helper — have
_forward call it and keep only its response-extraction logic. No behaviour
change (the channel-closed error message is now the shared generic one).

The spike (hass_client/spike/: bridge_a, bridge_b, rig, synthetic_light,

nothing in production imports the spike, only its own test did. Delete it.
docs/entity-bridge-decision.md keeps the rationale and the measured numbers as
the decision record, with a note that the harness is recoverable from git
history.

Each proxy entity service call now forwards as its own single
`sandbox/call_service` RPC. The per-loop-tick coalescing batcher
(_CallServiceBatcher / _BatchBucket) added complexity the first iteration
doesn't need, so it is removed; async_call_service calls _raw_call_service
directly. Behaviour is unchanged except a multi-entity area call now pays one
RPC per entity instead of one coalesced RPC.
Coalescing same-tick calls is recorded as a future optimisation in
docs/FOLLOWUPS.md (with the 200-light perf benchmark that validated it). Living
docs updated; the phase-history records are left as-is.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
A service call is never fire-and-forget: each batched caller awaits the
coalesced RPC's completion via its future, which resolves with the result or
the raised error, so every caller learns when its call finished. Batching only
shares the *wire* call, not the await; only a response *value* can't be
coalesced (hence the response bypass). Wording-only; no behaviour change.

test_phase4_subprocess -> test_subprocess
test_phase9_shutdown -> test_shutdown
test_phase13_proxies -> test_domain_proxies
test_phase14 -> test_schema_and_unload
test_phase19_devices -> test_device_registry

- Replace a stray function-local `import json` (json.dumps behind a bogus
'keeps json off the integration boot path' noqa) with HA's orjson
json_bytes_sorted helper for the call-service batch key.
- A response-returning entity call now bypasses the per-tick batcher.
Coalescing forces every caller in a bucket to share one combined response,
which is wrong when a caller needs its own value; response calls go out as
their own single-entity RPC. The batcher is now fire-and-forget only, so its
dead return_response plumbing is dropped.
- Also removes development-phase references from this file's docstrings.

Rewrite docs/auth-scoping-decision.md to lead with the shipped design: the
sandbox holds no credential and cannot fabricate a Context; main restores
attribution from a TTL cache of contexts it issued and falls back to

clearly-marked appendix for whenever the sandbox->main websocket lands. Update
the CLAUDE.md pointer to match.

optional (non-sandboxed entries omit it) instead of referencing an

Review feedback on ARCHITECTURE.md:
- Goal (§1) now names storage alongside setup/flow/entities/services/
events, and adds a short statelessness line (storage routes to main,
code is fetched at startup → wipe-and-restart safe).
- Auth (§10) trimmed to describe the current design — no credential, no
user — instead of narrating the token's removal. The removal history
lives in the changelog where it belongs.
- Dropped the "(the Iron Law: never monkey-patch private internals)"
parenthetical in §11; the plain "declared public hook rather than a
reach into private internals" already carries the point.

component table; the spawn command no longer carries --token; §8 documents
the implemented context restoration (TTL cache, own-id minting, ULID-trust
reasoning); §10 rewritten — no token, no system user, the future
Context-group-attribute note retained.
- OVERVIEW.md: auth comparison row, the spawn-command blocks, the
EventMirror context paragraph, the auth section (now "no credential" +
a Context-restoration subsection), and the file-pointer table.
- FOLLOWUPS.md: a plan-auth-context narrative entry; the open follow-ups now
describe the fresh-credential-when-WS-lands work and the Context group
attribute idea.
- auth-scoping-decision.md / CLAUDE.md: note the token + system user are now
also gone (already SUPERSEDED).

plan-auth-context Parts A/B/C — a design-review follow-up. The sandbox is
not an authenticated principal inside main and must never be able to author
a Context.
Part A — drop the unused token. The manager minted a per-group system-user
access token and passed it on --token; the runtime stored it
(SandboxRuntime.token) and never used it (no connection back to main to
authenticate). Removed end-to-end: --token argv (manager._default_command),
the token_factory wiring, SandboxRuntime.token field/param + --token CLI
arg, and SANDBOX_TOKEN in the Docker entrypoint / compose / docs.
Part C — drop the per-group system user. auth.py is deleted entirely
(async_issue_sandbox_access_token + async_get_or_create_sandbox_user gone),
along with bridge._async_system_user_id / _system_user_id. A genuinely
sandbox-originated context is now user_id=None — the honest shape, since no
user authored it.
Part B — context-id restoration. The bridge now seeds a context_id→Context
cache at every main→sandbox call-down site: the service forwarder (_forward)
and the proxy entity's service call (async_call_service, which threads the
entity's live Context). _resolve_context returns a cached Context verbatim
for a known id (restoring the original parent_id / user_id), so a
user-initiated action's attribution survives the round-trip. An unknown or
expired id mints a brand-new Context(user_id=None) with main's own trusted
id — never the sandbox-supplied ULID, whose embedded timestamp main cannot
trust (recorder/logbook order by it); the sandbox string is a cache key
only. The cache is bounded by a 15-minute TTL (lazy front-pruning, plus a
sanity count backstop); a miss is always safe.
Tests: known-id restore end-to-end via the forwarder; unknown→fresh with no
adopted id; no-forgery (the wire proto has no parent_id/user_id field); TTL
expiry degrades to a fresh context; spawn argv no longer carries --token.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
User refinement 2026-06-03:
- Bound the context cache by TIME (15-min TTL), not size. Volume is tiny
(only main→sandbox service-call contexts, echoed back within seconds).
- For an unknown context_id, main must mint a BRAND-NEW Context with its
OWN id — never adopt the sandbox's id. context_ids are ULIDs with an
embedded timestamp and main cannot trust the sandbox's clock (a crafted
ULID could back/forward-date events; recorder/logbook order by it). The
sandbox-supplied id is only a cache key, never the resulting Context's
identity. This corrects T2's current Context(id=context_id, ...) for
unknown ids.

User decision 2026-06-03: drop the sandbox system user entirely;
sandbox-originated contexts use user_id=None (no reason for the sandbox
to be a user right now). Future-work note recorded: a Context with a
group attribute is the better long-term answer for audit attribution,
but needs a core Context field change and waits until it's needed.

From review feedback on the architecture doc:
1. register_service schema serialisation: broaden serialize_schema's
fallback from `except (ValueError, TypeError)` to any exception (with a
warning log). An exotic custom validator could raise other types and
propagate, dropping the whole service registration on main. Now it
always degrades to schema=None — main registers the service, the
sandbox validates. Added test_schema_bridge.py covering the broad path.
2. Clarify in ARCHITECTURE.md that MAIN alone decides the sandbox group:
the group comes from main's classify(), the proxy overwrites
create_result["sandbox"] with the main-determined value, and the wire
FlowResult has no group field. The sandbox can shape its own forms but
cannot influence storage/routing. (Code was already correct; the doc
wording was loose.)
3. Note the --token is unused (sandbox is not an authenticated principal
inside HA) and slated to drop; the per-group system user's only live
use is context attribution, under reconsideration.
4. Document the intended context model: wire carries context_id only;
main restores parent_id/user_id from a seen-id cache so the sandbox can
never fabricate attribution; unknown ids get a fresh no-parent context.
Points 3+4 captured as a buildable follow-up: plans/plan-auth-context.md.

- whats-changed.md (batch tracker): added the `sandbox_v2` → `sandbox` rename
as a TL;DR bullet + a breaking-change entry (pre-release, wipe-and-restart).
- sandbox/CLAUDE.md: reworded the intro to current-state ("the sandbox rewrite,
formerly sandbox_v2"); clarified that the removed v1 previously occupied the
same paths the rewrite now lives at.
Historical records (STATUS-*.md, plans/*.md, docs/auth-scoping-decision.md)
keep their sandbox_v2 mentions intact — they document work done against those
paths.
The IGNORE_INTEGRATIONS_WITH_ERRORS = {"sandbox"} set tolerated v1's hassfest
violations while v2 stabilised. v1 is gone and the renamed integration (former
v2) is hassfest-clean, so the set + the two conditionals consulting it are
removed — keeping it would mask real errors in the renamed `sandbox`.
hassfest validate + generate: 0 invalid integrations, no generated-file changes
(sandbox has no config_flow → absent from config_flows.py; the NO_QUALITY_SCALE
entry was renamed by the Phase B sweep).
Phase B of plan-rename-sandbox. Mechanical identifier sweep + the structural
fixups the rename forced (tree compiles + both suites pass at the end):
- Bare-token sweep `sandbox_v2` → `sandbox` across all code + current-state
docs (excluding historical STATUS-*.md, plans/*.md, auth-scoping-decision.md
and the generated _pb2 gencode). Channel message strings, storage-key
namespace, client_id prefix, manifest domain, logger names all move.
- Prose sweep `Sandbox v2` → `Sandbox` (covers the `Sandbox v2: ` system-user
name prefix → `Sandbox: `).
- Protobuf: renamed sandbox_v2.proto → sandbox.proto (package `sandbox`) and
REGENERATED gencode (sandbox_v2_pb2 → sandbox_pb2) in both mirrors via the
isolated-venv recipe; removed the old _pb2 files. Drift guard clean.
- Name-collision fix forced by the rename: the client had both the impl module
`hass_client/sandbox.py` (exports SandboxRuntime) AND the `-m` launcher
subpackage `hass_client/sandbox_v2/`. Renaming the launcher to `sandbox`
collides with the impl module, so merged them — sandbox.py is now
`hass_client/sandbox/__init__.py` (parent-relative imports rewritten to
absolute `hass_client.*` per ruff TID252) with the launcher's __main__.py
kept. `python -m hass_client.sandbox` and
`from hass_client.sandbox import SandboxRuntime` both work.
- Docker entrypoint/compose/docs → `python -m hass_client.sandbox`.
- Client distribution renamed `hass-client-v2` → `hass-client` (import package
`hass_client` unchanged; matches the egg-info already installed).
Tests green: HA-side 201 passed, client 70 passed. prek clean on changed set.
Phase A of plan-rename-sandbox. Pure renames via git mv to preserve blame:
homeassistant/components/sandbox_v2 → homeassistant/components/sandbox
tests/components/sandbox_v2 → tests/components/sandbox
sandbox_v2 → sandbox
sandbox/hass_client/hass_client/sandbox_v2 → sandbox/hass_client/hass_client/sandbox
sandbox/proto/sandbox_v2.proto → sandbox/proto/sandbox.proto
The untracked tests/testing_config/.storage/sandbox_v2 dir is a runtime test
artifact (not tracked); left as-is. The tree does NOT import or pass tests
after this commit — Phase B sweeps every sandbox_v2 identifier + regenerates
the protobuf gencode.
Multi-stage python:3.14-slim image that runs the hass_client sandbox
runtime (python -m hass_client.sandbox_v2). Installs homeassistant +
hass_client into a venv; no pre-baked integration requirements (runtime
pip-installs them on demand), no git (codeload tarball fetch), non-root,
no volumes, no healthcheck, env-driven entrypoint via tini. Closes the
pip/egress runtime gap flagged by plan-ephemeral-sources: the container
is where pip + network egress live.
Transport caveat: unix socket (T3) today, websocket (T4) later — not a
remote-ready artifact. The docker-compose.test.yml captures the intended
same-host unix-socket harness but does not run against today's manager
(private mkdtemp socket path + spawn-not-attach model); both gaps are
documented, not hacked.

Docs sweep for the stateless-sandbox feature (d4b7aef732): protocol.py
integration_source field, OVERVIEW entry-lifecycle + statelessness
section, CLAUDE.md resolver-hook contract + sha-pin rule + pip/egress
follow-up, architecture.html fetch-before-setup, whats-changed box ticked.
The sub-session wrote these files but didn't land the second commit;
committing them here. STATUS flags two honest follow-ups: tree-vs-ref
verification trusts GitHub's content-addressed codeload URL rather than a
full git-tree-hash; async_process_requirements (pip for custom deps) is
unconfirmed in the bare-HA sandbox — pairs with plan-docker.

Make sandboxes hold no integration code: main attaches a typed
IntegrationSource to EntrySetup (builtin no-op, or a git source pinned to
an exact commit sha), and the sandbox fetches custom (HACS) code into
<config>/custom_components/<domain> before async_setup.
- proto: IntegrationSource sub-message + EntrySetup.integration_source (10);
both _pb2 mirrors regenerated.
- core sources.py: registered-resolver hook (async_register_sandbox_source_
resolver) keeping core HACS-agnostic; builtin short-circuit; a custom
domain with no resolver raises. Resolver pins ref to a sha (no core I/O).
- router: _entry_setup_payload resolves + sets integration_source.
- client sources.py: codeload-tarball fetch (injectable primitive),
process-lifetime (url, ref) cache, manifest.json verification; wired into
entry_runner before setup.
- tests: resolver registry + payload (HA side), tarball fetch/cache/verify
with local fixtures (client side). No network in any test.

T3 (1eaa79d261) + T5 (42560c6cd0) landed. Unix socket transport
(opt-in via SandboxManager(transport="unix"); stdio remains default),
ws:// rejected with NotImplementedError, wire-protocol docs current.
191 + 62 tests green; drift guard clean. T1→T2→T3→T5 complete; T4 (WS)
out of scope. UnixSocketTransport is StreamTransport-over-unix-streams
(no new class). Socket lives in a short tempdir to dodge the ~108-char
sun_path limit; teardown force-closes accepted clients to avoid a
wait_closed() hang.

Bring the wire-protocol docs to the current protobuf + pluggable-transport
reality and tick the transport trackers.
* OVERVIEW.md / architecture.html: rewrite the transport row, the spawn
prose, and the channel section to describe the three-layer
Channel/Codec/Transport split, ProtobufCodec as the production wire,
the Ready-frame handshake (no stdout text marker), length-prefixed
framing, and stdio + unix transports (websocket reserved/future). Drop
the stale --url ws:// example and JSON-line wording.
* channel.py docstrings (both mirrors): ProtobufCodec is the production
codec; JsonCodec is the registry-free channel-core test/debug wire.
* protocol.py docstring: messages are typed protobuf (REGISTRY +
sandbox_v2.proto); the payload shapes listed are the logical contract.
* sandbox.py: SandboxRuntime docstrings note the --url-selected transport
(stdio default, unix opt-in, ws reserved).
* whats-changed.md: tick the protobuf-wire + typed-handlers boxes (T2
360e454330) and pluggable-transports box (T3 1eaa79d261).

Add an opt-in unix-domain-socket control-channel transport alongside the
default stdio transport. The manager opens a listening unix socket, passes
its path to the subprocess as --url unix://<path>, and the runtime dials
back; the manager is the server. Both transports reuse StreamTransport's
length-prefixed framing, so no dedicated unix transport class is needed.
* Manager: SandboxManager(transport="stdio"|"unix") (default stdio,
unchanged behavior). _run_one splits into stdio/unix paths sharing a
_supervise_until_exit helper; the unix path creates the socket in a
short per-attempt tempdir (sidesteps the ~108-char sun_path limit),
races accept against early exit, and force-closes lingering accepted
connections (server.close_clients) so wait_closed cannot hang.
* CommandFactory is now (group, url) -> argv; the manager owns the
transport and hands the factory the right --url.
* Runtime: --url scheme selects the transport — stdio:// (default /
absent), unix://<path>, or ws://|wss:// (reserved, rejected with a
clear not-implemented error). New _transport_scheme + _open_unix_channel.
* Tests: unix round-trip + socket cleanup (core), scheme selection + ws
rejection + unix round-trip (client); existing factories updated to the
(group, url) signature.

T2 landed as 360e454330 (64 files, +3762/-1046). Sub-session report:
- default production codec = ProtobufCodec; ~20 handlers + ~69 test
sites converted atomically; 189 + 53 tests green; prek + drift guard clean.
- 4 reasoned deviations (bare Channel ctor keeps JsonCodec with proto
built explicitly at production sites; JsonCodec stays registry-free for
channel-core tests; grpcio-tools out of project deps via throwaway venv;
sandbox-side context cache deferred until a consumer needs it).
- One gotcha fixed: a test stub returning a plain dict hung the router's
untimed channel.call under ProtobufCodec — relevant for T3/T5.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Atomic switch of the control channel from JSON dicts to typed protobuf
messages, completing transport T2 on top of T1's Transport/Codec seam.
- Codec owns the registry: each side builds a type -> (request_cls,
result_cls) map from its own _proto mirror and constructs
ProtobufCodec(registry). The concurrency-critical Channel core stays
fully codec-agnostic; response frames now carry `type` so the stateless
codec resolves the result class on both encode and decode.
- Proto refinements (locked 2026-06-03): EntityDescription wraps EntityInfo
(identity: Description + DeviceInfo) and InitialState (state +
capabilities + attributes); ServiceResponse is a typed envelope inside
CallServiceResult (proto3 optional, no has_response bool); StateChanged
is flattened and carries optional context_id; FireEvent carries optional
context_id. Dynamic fields cross as Struct/ListValue.
- Context security model: the sandbox only ever sends a context_id string;
parent_id / user_id never cross the wire. Main resolves the id to its own
authoritative Context via SandboxBridge._resolve_context — reusing a
cached Context or minting a fresh one attributed to the sandbox system
user with no parent_id — for state_changed, fire_event and call_service.
- Generated _pb2 mirrors checked into both no-cross-import trees; regen via
sandbox_v2/proto/generate.sh (isolated venv so the protobuf==6.32.0 pin is
never bumped). Drift guard wired as a manual-stage prek hook that degrades
gracefully when uv is absent.
- Default codec is protobuf (manager + runtime channel construction);
JsonCodec is retained registry-free as the test wire for the channel-core
tests. protobuf added to the client pyproject + the HA manifest
requirements; grpcio-tools stays out of the project venv by design.
- ~20 handlers converted to typed messages across bridge.py, entry_runner,
flow_runner, entity_bridge, service/event mirrors, sandbox_bridge and the
schema bridge; ~69 test call/push sites translated with no assertion
loosening (semantics shifts forced by proto presence are commented).

User direction 2026-06-03 — capture before T2 launches.
Proto schema changes:
- Group fields the way HA organizes them. EntityDescription (wire) gets
an EntityInfo sub-message (HA's EntityDescription dataclass fields +
DeviceInfo) and an InitialState sub-message (initial state +
capabilities + initial attributes). Nested EntityInfo.Description
avoids the recursive-name clash.
- ServiceResponse is now a typed message (was Struct in the draft); the
dynamic payload sits inside it as a Struct field. CallServiceResult
drops the has_response boolean in favor of proto3 `optional`.
- StateChanged gains an optional context_id (was missing entirely).
Context discipline (security):
- parent_id and user_id are NEVER serialized on outbound messages from
sandbox. The wire carries context_id only.
- Sandbox keeps a local context_id -> Context cache main populates when
relevant (e.g. main pushing a state-changed for a context the sandbox
needs).
- Main resolves context_id to its authoritative Context at dispatch.
If no such Context exists, main mints one attributed to the sandbox's
system user (no parent_id) and registers it.
WebSocket transport is now flagged COMPLETELY OUT OF SCOPE for this
effort (was "deferred"). T1's Transport Protocol is shape-compatible
with a future WebSocketTransport, but no WS code/deps/auth surface
lands in this batch.

T1's STATUS surfaced one design refinement to ratify before T2 coding:
the type -> (request_cls, result_cls) protobuf registry lives on the
codec, not on Channel.register. Ratified 2026-06-03.
The argument (from T1's sub-session): keeping the pairing in the codec
preserves the plan's stated safety property — the concurrency-critical
Channel core stays codec-agnostic. ProtobufCodec(registry) / JsonCodec(registry)
on each side; Channel.register signature unchanged.
For responses to be decodable without per-call state, the proto Frame
envelope carries `type` on response frames too (already a field; just
populate it).

T1 (Transport/Codec seam + Ready frame) shipped green at 8389f7ad96.
T2 (protobuf wire + typed handlers) is an atomic big-bang — flipping the
default codec to protobuf and switching ~20 handlers to typed messages
forces ~69 wire-call test sites to convert in lockstep, so it cannot land
in safe green increments the way T1 was designed to. Rather than ram a
big-bang through and risk a broken tree (or silently weakened test
assertions during a 69-site rewrite), this STATUS hands off:
* the cleared codegen toolchain gate + verified recipe (isolated venv,
grpcio-tools 1.80.0, gencode min-runtime 6.31.1 ⊆ pinned 6.32.0)
* the resolved T2 design — including the response-typing solution the
plan left implicit (carry `type` on response frames) and a refinement
to keep the request/result class registry in the codec (Channel core
stays codec-agnostic) for the parent to approve
* the full T2 file/test work breakdown, and the small T3/T5 shapes
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Split the control channel into three layers so the wire format and the
byte transport can each be swapped without touching the concurrency-
critical dispatch core:
* Channel — dispatch core (pending map, inflight semaphore, register/
call/push/close); speaks Frame objects, never raw bytes.
* Codec (Protocol) + JsonCodec — Frame <-> bytes. JsonCodec is
line-compatible with the old wire shape.
* Transport (Protocol) + StreamTransport — whole frame blobs over a
reader/writer pair using a 4-byte big-endian length prefix (caps frame
size at 16 MiB and aborts the channel on overflow). Channel.from_transport
is the drop-in seam for a future WebSocketTransport.
Replaces the stdout text marker (sandbox_v2:ready) with a MSG_READY
*frame* sent as the channel's first message; the manager registers a
handler for it and flips to "running" on arrival, so stdout now carries
nothing but channel frames. Net behavior identical — still JSON, still
stdio — only the framing and handshake changed.
Both channel.py mirrors and protocol.py mirrors updated in lockstep.
Handshake/marker test assertions updated; added coverage for the
from_transport seam via an in-memory queue transport.

Broad readers (template, group, homekit) and source-entity helpers
(min_max, statistics, trend, threshold, derivative, integration,
utility_meter, filter, mold_indicator, bayesian, generic_thermostat,
generic_hygrostat, switch_as_x, history_stats, proximity) read foreign
entities / registries a sandboxed integration can't see under lockdown,
so pin them to main. prometheus/alert are config_flow:false (YAML-only)
and already stay on main, so they're not added.

reconstruct_schema now rebuilds real Selector and data_entry_flow.section
objects instead of collapsing them to a pass-through validator, so when the
flow manager re-serialises main's schema for the frontend it reproduces the
sandbox's original list verbatim (selectors keep their widget). The
serialize-side _has_data_schema fallback now logs the dropped schema's repr
at warning so the lossy path is visible.

Client EntityBridge now listens on EVENT_ENTITY_REGISTRY_UPDATED and
EVENT_DEVICE_REGISTRY_UPDATED and re-describes + re-sends MSG_REGISTER_ENTITY
for tracked entities, guarded by a description hash to avoid event storms.
Main's _handle_register_entity updates the existing proxy in place (refreshing
the mirrored _attr_* fields and the DeviceEntry) instead of adding a duplicate.

Proxies all register under the shared sandbox_v2 platform_name, so the
entity-registry uniqueness key (domain, "sandbox_v2", unique_id) collided
when two integrations in one group reused a unique_id. Namespace the proxy

Carry a structured error_data field on the error frame for vol.Invalid /

Phase 7's RefreshToken.scopes + websocket-dispatcher enforcement was
built for a sandbox->main websocket that never shipped, so no code path
ever exercised the scope check end-to-end. Revert the whole mechanism
from core HA and keep the sandbox on a plain system-user token.
Phase A (core revert, lockstep):
- auth/models.py: delete the RefreshToken.scopes field.
- auth/__init__.py + auth/auth_store.py: delete the scopes= parameter
and the on-disk serialize/deserialize of the scopes key. The load
path now pops a legacy scopes key silently (option A: no migration,
no storage-version bump) so pre-existing scoped tokens load fine.
- websocket_api/connection.py: delete self.scopes, the _scope_allows
helper, and the async_handle enforcement branch.
Phase B (sandbox helper):
- sandbox_v2/auth.py: delete SANDBOX_TOKEN_SCOPES; identify the refresh
token by the one-token-per-system-user invariant instead of matching
a scope set. System-user token type is unchanged.
Tests:
- Delete tests/components/websocket_api/test_scopes.py.
- Delete the scoped-token round-trip cases from tests/auth/test_init.py.
- Add a regression test that an on-disk token with a legacy scopes key
loads without error and drops the field.
- Update sandbox_v2 test_auth assertions to the plain-token contract.
Phase C (docs): mark auth-scoping-decision.md SUPERSEDED; drop the
auth row from the core-HA-modified lists in CLAUDE.md / architecture
.html; rewrite the scoped-auth sections in OVERVIEW.md and
architecture.html; add a re-introduce follow-up in FOLLOWUPS.md.

A2 landed (commit 4c85363668). Mark the monkey-patch-removed item done
in the batch landing tracker and check in the sub-session's STATUS report.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Phase A2 of plan-sandbox-context: remove the module-level `Store`
rebinding now that the `current_sandbox` contextvar (A1) is the single
source of truth for sandbox Store IO.
Load-bearing correctness fix (surfaced by A1's STATUS): the contextvar
save branch moves DOWN from `Store.async_save` to
`Store._async_write_data`. `async_delay_save` and the FINAL_WRITE flush
bypass `async_save` entirely — they funnel through
`_async_handle_write_data` -> `_async_write_data`. While `RemoteStore`
existed it overrode `_async_write_data` and masked this; deleting it
would have silently routed delayed/final-write saves to the sandbox
tempdir. Branching at `_async_write_data` covers async_save,
async_delay_save, and FINAL_WRITE uniformly. The redundant `async_save`
branch is removed.
Deletions:
- `hass_client/remote_store.py` (the subclass + installer)
- `hass_client/tests/test_remote_store.py` (covered by the contextvar
tests + the new delayed-save regression test)
- the `install_remote_store` call/teardown in `SandboxRuntime.run`
- the explicit `data.store` swap in `_load_restore_state` (the
contextvar reaches the import-captured `Store` reference)
New regression test `test_delayed_save_flushes_through_bridge` asserts
`async_delay_save` + EVENT_HOMEASSISTANT_FINAL_WRITE route through the
bridge. Docs (CLAUDE.md, OVERVIEW.md, FOLLOWUPS.md, architecture.html)
rewritten around the contextvar.
Tests: 190 core (sandbox_v2 + storage + restore_state) + 50 client all
green; prek clean.

Three new plans queued ahead of fidelity/transport/ephemeral/docker:
- plan-sandbox-context: replace install_remote_store monkey-patch with a
current_sandbox ContextVar in homeassistant/helpers/, set by the runtime
before warm-load. Same primitive will later carry cross-sandbox IR/RF
calls. Refined via phx:plan; Q1/Q2/Q3 locked (defer IR/RF, A1+A2 split,
docstring+assertion guard).
- plan-strip-auth-scopes: revert Phase 7's RefreshToken.scopes mechanism
from core HA. No consumer shipped; on-disk scopes key dropped silently
on load. Re-introduces when the sandbox->main WS transport lands.
- plan-rename-sandbox (last): rename sandbox_v2 -> sandbox once v1 is fully
gone, including hassfest IGNORE cleanup.
Decisions locked 2026-06-03:
- builtin lockdown: (a) blanket ALWAYS_MAIN for Category A+B helpers.
- ephemeral-sources resolver: (c) generic resolver hook.
STATUS-plan-sandbox-context-A1.md added (sub-session report). The report
surfaced a correctness prerequisite for A2: async_delay_save and the
FINAL_WRITE flush bypass async_save and go through _async_write_data
directly. A2 must therefore move the contextvar save branch down to
_async_write_data before deleting RemoteStore, or delayed saves would
silently land in the sandbox tempdir. The plan's A2 section now spells
this out.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Add a `current_sandbox` ContextVar in core HA (homeassistant/helpers/
sandbox_context.py) that `Store.async_load/save/remove` read at call
time to route storage IO to main, replacing the module-level
`Store` rebinding done by `install_remote_store`. Reading the
contextvar inside each IO method is a single source of truth
regardless of how `Store` was imported, so it reaches the helpers
that captured the original `Store` at module load (restore_state,
the registries) — which the rebinding never could.
This is the additive half (Phase A1): the contextvar branch is added
alongside the existing `install_remote_store`, both paths active. The
contextvar branch is the first line of each IO method, so it serves
the IO; `RemoteStore` + the `_load_restore_state` workaround stay until
A2 deletes them once A1 bakes on dev.
- helpers/sandbox_context.py: `current_sandbox` ContextVar + the
`SandboxBridge` Protocol (store methods only; IR/RF deferred).
- helpers/storage.py: `_async_load_data` fetches the wrapped envelope
via the bridge when the contextvar is set (migration block unchanged
— design choice B); `async_save`/`async_remove` early-return through
the bridge.
- hass_client/sandbox_bridge.py: `ChannelSandboxBridge` implementing the
three store methods over MSG_STORE_LOAD/SAVE/REMOVE (bodies lifted from
RemoteStore, incl. the orjson preserialise on save).
- hass_client/sandbox.py: build the bridge and `current_sandbox.set`
before warm-load + handler registration; assert it was unset first
(Risk #3); reset the token on teardown.
- hass_client/tests/test_sandbox_bridge.py: the five Phase A1 tests plus
a direct ChannelSandboxBridge wire-mapping test.

The numeric compat gate (Phase 17: 99.67% full sweep, 99.97% v1 baseline)
is met. Removing v1 ahead of the "v2 shipped a stable release" condition,
relying on git history for rollback.
Deletes homeassistant/components/sandbox, tests/components/sandbox, and the
top-level sandbox/ dev dir; regenerates config_flows.py (drops the v1
"sandbox" entry); updates current-state v2 docs (historical STATUS-phase-*
records left intact).

Phase 7 introduced `SharingConfig` (`share_states`,
`share_entity_registry`, `share_areas`) on the runtime + the matching
`SandboxGroupConfig` on the manager + `--share-*` CLI flags +
`DEFAULT_GROUP_CONFIGS` defaults, intended for a future subscription
consumer that observes main's state stream. The consumer never landed.
~40 LOC of dead surface across five files plus an entire test module
(`test_sharing_config.py`, 7 tests). Carrying unwired flags risks
readers assuming functionality that isn't there — Phase 16's failure
categoriser had to specifically call this out.
Removed:
- `SharingConfig` + `sharing=` constructor param + `__all__` entry
(`sandbox_v2/hass_client/hass_client/sandbox.py`).
- `--share-states`/`--share-entity-registry`/`--share-areas` argparser
entries (`__main__.py`).
- `SandboxGroupConfig`, `DEFAULT_GROUP_CONFIGS`, `group_config()`
accessor, and `--share-*` argv expansion in `_default_command`
(`homeassistant/components/sandbox_v2/manager.py`).
- `sharing=` parameter on the in-process plugin.
- `test_sharing_config.py` (whole file).
- `test_manager.py` group_config tests.
- Sharing assertions in `test_sandbox_runtime.py`.
Replaced with `sandbox_v2/docs/design-share-states.md` — the contract
for the future consumer: goal, entity_id alignment constraint
(sandbox-side automations referencing `light.kitchen` must see main's
actual entity_id, not whatever the sandbox's local EntityRegistry
would have generated), `share/subscribe_*` mechanism sketch, per-
sandbox allow-list filtering on main, and the open questions
(direction, read-only semantics, device/area mirroring as P19
follow-on, fan-out perf).
`OVERVIEW.md`, `CLAUDE.md`, `docs/FOLLOWUPS.md`, and
`generate_backlog.py`'s `dependencies-not-shared` description all
repoint at the new design doc.
No core HA files touched. 140 + 47 tests passing (hass_client drops
the 7 sharing-config tests; HA-side drops 2 group_config tests).
plan.md updated with Phase 18/19/20 phase blocks + ✅ ticks.

Sandboxed entities that carry `device_info` now produce matching
`DeviceEntry` rows in main's `device_registry`, linked to the
sandboxed `config_entry_id`. Area assignment now propagates through
HA's standard device → entity inheritance path (Phase 5's entity
bridge alone left the entity registered without a device_id, so the
device_registry was empty for sandboxed integrations).
Sandbox side (`hass_client/entity_bridge.py`):
- `_serialise_device_info` flattens `DeviceInfo`'s TypedDict shapes
into JSON-safe lists/strings (identifiers/connections as lists of
two-element lists, via_device as list, entry_type as `StrEnum.value`,
configuration_url as string).
- `_describe_entity` appends a `device_info` key to the wire payload
when the entity exposes one.
Main side (`homeassistant/components/sandbox_v2/`):
- `SandboxEntityDescription` gains `device_info` / `device_id` fields.
- `from_payload` runs `_deserialise_device_info` to rebuild typed shapes.
- `_handle_register_entity` pre-creates the `DeviceEntry` via
`dr.async_get_or_create(config_entry_id=description.entry_id,
**device_info)`, pins the returned `device.id` on the description.
- Proxy base sets `_attr_device_info` so `EntityPlatform.async_add_entities`
reuses the same `DeviceEntry` (idempotent on identifiers/connections)
and wires `entity.device_entry`. No per-domain proxy edit needed —
all 32 inherit from the base.
No new core HA changes (`device_registry.async_get_or_create` is
already public).
Tests:
- `tests/components/sandbox_v2/test_phase19_devices.py` — six end-to-
end cases (DeviceEntry creation + entry-id linkage, proxy device_id
propagation, backwards-compat with payloads omitting device_info,
area assignment surfacing, invalid device_info rejection, payload
round-trip).
- `sandbox_v2/hass_client/tests/test_entity_bridge.py` — three new
cases.
140 + 54 tests passing.

ESPHome serial / BLE proxy (and Broadlink-style IR/RF) are coupled
in-process today: setup-time enumeration + send-calls happen via
Python calls/events the bridge doesn't cross. Pure-built-in pairs are
fine (same `built-in` sandbox group); a built-in producer paired with
a custom-integration consumer would split across `built-in`/`custom`
and break.
Captured the constraint + two fix shapes (classifier "co-locate with
X" hint vs extending Phase 6's event mirror beyond `<owned_domain>_*`)
in the three places that track open follow-ups:
- `sandbox_v2/CLAUDE.md` — Open follow-ups
- `sandbox_v2/docs/FOLLOWUPS.md` — Still open
- `sandbox_v2/OVERVIEW.md` — Where the design is still open
IR/RF is the simpler case (one-way command flow, no bidirectional
stream or enumeration) but still needs dedicated cross-sandbox routing
to land the consumer's send-call on the producer.

`sandbox_v2/hass_client/` is a separate uv-managed Python package that
the HA-core sandbox_v2 integration spawns as a subprocess per sandbox
group. It hosts a private `HomeAssistant`, drives each sandboxed
integration's `ConfigFlow` and `async_setup_entry`, mirrors entity /
service / event registrations back to main over a stdio JSON-line
`Channel`, and routes Store reads/writes through main via `RemoteStore`.
`sandbox_v2/docs/`:
- `entity-bridge-decision.md` — Phase 1 spike: why Option B
(action-call forwarding via `sandbox_v2/call_service`).
- `auth-scoping-decision.md` — Phase 7: why `RefreshToken.scopes` is
a generic primitive (vs a sandbox-private subclass).
- `FOLLOWUPS.md` — narrative of Phases 12–17 (concurrent dispatcher,
28-domain proxy fill-in, flow-schema bridge, baseline compat sweep,
cross-integration BACKLOG generation, `ConfigEntry.sandbox` field).
Compat sweep tooling:
- `run_compat.py` — Phase 15: v1's 37-integration baseline runner;
output to `COMPAT.md` (curated) + `COMPAT.csv`.
- `run_compat_full.py` — Phase 16: 807-integration cross-sweep at
asyncio concurrency=6 (~12 min wall); output to `COMPAT_FULL.md`
+ `COMPAT_FULL.csv`.
- `categorize_failures.py` — regex-rule failure categoriser feeding
`BACKLOG.md` + `BACKLOG_FAILURES.json`.
- `generate_backlog.py` — auto-draft skeleton for BACKLOG.md.
Headline result (after Phase 17): 99.67% test-level pass rate across
807 integrations; baseline 99.97%. Both clear the 99.5% v1-removal
threshold.
`sandbox_v2/STATUS-phase-{3..18}.md` are the authoritative landing
notes for each phase — every "Things to flag" surfaced is in there.

The HA-core side of the sandbox v2 rewrite: routing, lifecycle, flow
forwarding, entity bridging, service/event mirroring, scoped auth,
opt-in data sharing, Store routing, graceful shutdown.
Lives at `homeassistant/components/sandbox_v2/`. Designed alongside the
client library at `sandbox_v2/`; see `sandbox_v2/OVERVIEW.md` for the
full architecture and `sandbox_v2/docs/FOLLOWUPS.md` for the phase-by-
phase narrative.
Built on the core hooks added in the preceding commits:
`ConfigEntries.router` + `ConfigEntry.sandbox` + `RefreshToken.scopes`
+ `EntityComponent.async_register_remote_platform`.
32 domain proxy classes under `entity/` cover every entity domain v2
supports. Bridge translates each proxy method into a
`sandbox_v2/call_service` RPC via a per-loop-tick batcher (coalesces
multi-entity area calls into single RPCs).

Adds an `IGNORE_INTEGRATIONS_WITH_ERRORS` set to hassfest's main loop
so v1 sandbox's pre-existing hassfest gates (CONFIG_SCHEMA, manifest
version, missing services.yaml, mypy signature drift in entity proxies)
don't block validation of the rest of the tree. v1 is being superseded
by sandbox_v2 (see `sandbox_v2/OVERVIEW.md`) — accepting v1's existing
state for now is preferable to either fixing every gate in code that
will be removed, or skipping hooks.
Also adds `sandbox_v2` to `NO_QUALITY_SCALE` (internal integration)
and ships an empty `sandbox_v2/services.yaml` placeholder — `bridge.py`
calls `hass.services.async_register` dynamically per sandboxed
integration; those services are owned by the sandboxed integrations.
`homeassistant/generated/config_flows.py` is regenerated to include
`sandbox` (v1 had drifted out of the registry).

Three small additive surfaces that the sandbox_v2 integration plugs
into. Each is additive and a no-op when nothing registers against it.
config_entries.py:
- `ConfigEntries.router: ConfigEntryRouter | None` attribute + the
`ConfigEntryRouter` Protocol. Consulted from three sites:
`ConfigEntriesFlowManager.async_create_flow`, `ConfigEntries.async_setup`,
and `ConfigEntries.async_unload`. Returning `None` falls through to
the existing path.
- `ConfigEntry.sandbox: str | None` optional field. Carries the routing
tag without polluting `entry.data`. Persisted via `as_dict` /
`as_storage_fragment` only when non-None; read via `dict.get` so
pre-existing stored entries load with `sandbox=None`. Mutable via
`ConfigEntries.async_update_entry(entry, sandbox=)`. `ConfigFlowResult`
gains a `sandbox` TypedDict key the framework reads at entry
construction (same plumbing shape as `minor_version` / `options` /
`subentries`).
entity_component.py:
- `EntityComponent.async_register_remote_platform(config_entry, platform)`
lets sandbox_v2 attach a pre-built remote `EntityPlatform` without
re-discovering the local integration. Mirrors `async_setup_entry`'s
`_platforms[entry_id] = platform` assignment as a public hook.
Tests:
- `MockConfigEntry` picks up a `sandbox=` kwarg threaded through to
`ConfigEntry.__init__`.
- Six new `test_config_entries.py` cases for the `sandbox` field:
default-none + omitted-from-storage, persisted-when-set, round-trip,
absent-from-storage-loads-as-none, async_update_entry-sets-sandbox,
cannot-be-set-directly.

Adds an optional `scopes: frozenset[str] | None` attribute to
`RefreshToken` and threads it through `AuthManager.async_create_refresh_token`
and `AuthStore` (sorted list on disk, optional on read — no version bump).
`ActiveConnection` reads scopes off the connecting token and a new
`_scope_allows` helper in the websocket dispatcher rejects out-of-scope
commands with `ERR_UNAUTHORIZED`. Existing unscoped tokens (`scopes is
None`) are unaffected — the gate is a no-op for them.
This is the primitive the sandbox_v2 integration uses to issue
namespace-scoped tokens (`{"sandbox_v2/", "auth/current_user"}`) to
sandbox subprocesses, so a sandbox-resident integration cannot escalate
to the rest of the websocket API.

After 'uv pip install -r requirements_ha.txt' (which pulls in
requirements_all.txt), the integrations previously listed as
'Not Tested (missing dependencies)' import and run:
- rest: 10/10 pass (needed xmltodict)
- logbook: 55/55 pass (needed sqlalchemy + numpy + turbojpeg)
- command_line: 7/7 pass
- trend: 9/9 pass
Promote them into the main pass table; the totals now read 35 of 37
fully pass, 955/957 tests (99.8%).
conversation imports too (hassil was already in pyproject.toml deps
but the report listed it as missing) but 8 of 21 tests fail and the
run deadlocks at tests 20-21 — moved into a new 'Newly runnable, still
investigating' section instead of the pass table.
Add a Setup section pointing at requirements_ha.txt and the pyitachip2ir
macOS caveat.

The sandbox client's pyproject.toml only carries the minimal set of
packages needed to run the client library and its own tests. Running
HA Core's per-integration test suites through the sandbox plugin needs
the full integration dependency tree (hassil for conversation,
xmltodict for rest, sqlalchemy+numpy+turbojpeg for logbook, …).
requirements_ha.txt pulls in ../../requirements_all.txt and
../../requirements_test.txt with paths relative to the file, so it
keeps working from any cwd. Comment notes the macOS pyitachip2ir
build caveat and the workaround.

The shell version required a manually-prepared
/tmp/all_integrations.txt and used a perl-based timeout shim.
run_all_sandbox_tests.py auto-discovers integrations from the core
tests directory and uses subprocess timeouts, so the .sh is no longer
needed.

architecture.html already covers system diagrams, flow diagrams, file
structure, websocket API, key classes, and test results, so the prose
deep-dive in ARCHITECTURE.md was largely overlapping. Keep the bits
that weren't already in OVERVIEW.md and drop the rest:
- Startup sequence (host startup, sandbox process startup, host/sandbox
entity platform setup) as a new section after High-Level Flow.
- The RemoteLightEntity worked example plus the static/dynamic property
caching rationale, inside Entity Platform Architecture.
- Entity Method Compatibility (which domains already expose async
wrappers; the cover.toggle gap).

Pointers to OVERVIEW.md, ARCHITECTURE.md, architecture.html, the
test driver scripts, and SANDBOX_COMPAT.md; quick-start for running
the sandbox client and the core test suites through it.

Move ARCHITECTURE.md, OVERVIEW.md, CLAUDE.md, the architecture HTML,
the test-runner scripts and TEST_RESULTS.csv into this directory next
to the hass_client subtree, so the entire sandbox project lives on the
sandbox branch of core (only the HA integration at
homeassistant/components/sandbox/ stays put for HA's loader).
Adjust the relative paths the moved files used to point at the old
sibling checkouts:
- hass_client/pyproject.toml: uv source homeassistant -> ../..
- run_all_sandbox_tests.{py,sh}: cd into ./hass_client and walk to
../../tests/components/ for the core test suites
- analyze_failures.py: write TEST_RESULTS.csv next to the script

Restructure the sandbox websocket API around three commands instead of
a single event subscription: sandbox/register_service registers a
proxy service on the host that forwards calls into the sandbox,
sandbox/call_service lets the sandbox invoke a host service while
preserving its context, and sandbox/service_call_result returns the
sandbox's response back to the originating host caller.

These 32 files (light.py, sensor.py, etc.) each only registered an
async_add_entities callback. Now that RemoteHostEntityPlatform adds
proxy entities directly to the EntityComponent, they are dead code.
Also removes the unused register_platform_callback and
AddEntitiesCallback from SandboxEntityManager.

Replace the async_forward_entry_setups + per-domain platform file
approach with RemoteHostEntityPlatform. This EntityPlatform subclass
is added directly to the domain's EntityComponent and manages proxy
entities without needing 32 identical platform files.
The platform is created on-demand when the first entity for a domain
is registered by the sandbox.

Config entries can now set options["sandbox"] = "group_name" to be
assigned to a named sandbox group. Entries sharing the same group
string run in the same sandbox process. The sandbox config entry
discovers group members via entry.data["group"].
The explicit entries list (entry.data["entries"]) still works for
test infrastructure compatibility.

Split the monolithic entity.py (1900 lines) into a per-platform
package structure under entity/. Each domain gets its own file,
making the codebase easier to navigate and extend.

Brings total supported platforms to 32. Device tracker supports
both TrackerEntity (GPS) and ScannerEntity (router/BLE).
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Implements sandbox proxy entities for: alarm_control_panel, button,
calendar, climate, cover, date, datetime, fan, humidifier, lawn_mower,
lock, media_player, notify, number, remote, select, siren, text, time,
update, vacuum, valve, water_heater, weather.
Total supported platforms: 30 (up from 6).
Each proxy class caches state from sandbox pushes and forwards service
calls back to the sandbox via the existing websocket command channel.

Adds SandboxBinarySensorEntity, SandboxSensorEntity, SandboxSwitchEntity,
SandboxSceneEntity, and SandboxEventEntity proxy classes. Also adds
device_class and state_class to entity registration.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Implements the sandbox integration that manages config entries running
in isolated processes. Proxy entities on the host forward service calls
to sandbox processes via websocket and cache state pushed back.
Supports entity, device, and area targeting for service calls.

Move HybridServiceRegistry out of runtime.py into its own
sandbox_service_registry.py module, expand the websocket API error
translator to handle ServiceNotSupported and sandbox/call_service, and
extend conftest_sandbox with additional fixtures.

New class that wraps an EntityPlatform on the sandbox side to intercept
async_add_entities calls. When an integration adds entities, they are:
1. Added locally as normal
2. Registered with the host via sandbox/register_entity
3. State changes forwarded to the host
4. Method calls from the host dispatched to local entities
This replaces the post-setup iteration approach in SandboxEntityBridge
with a clean intercept at the async_add_entities boundary.

Three fixes:
- Stop host HA explicitly after tests to cancel lingering timers that
caused verify_cleanup teardown errors (scene, todo, etc.)
- Guard HybridServiceRegistry remote fallback: only try remote for
services that exist in the remote cache, preventing wrong
ServiceNotFound errors in nested service calls
- Remove manual INSTANCES.remove; let async_stop handle cleanup
31 of 33 integrations fully pass (878/880 tests, 99.8%).
The 2 remaining failures are pre-existing logbook platform issues.

Tests using pytest-freezer's `freezer.move_to()` hang when a live
websocket is active because time jumps break async heartbeat timers.
Detect the freezer fixture in pytest_runtest_setup and fall back to
the base plugin (no websocket) for those tests.
All 9 input helper integrations now pass (189/189 tests).

New pytest plugin (hass_client.testing.conftest_sandbox) that boots a host
HA Core with websocket_api + sandbox integration, creates a sandbox auth
token, and connects a RemoteHomeAssistant to it via a live websocket. This
allows running the full HA Core input_boolean test suite (16/16 tests)
through a real sandbox round-trip.
Key pieces:
- conftest_sandbox.py: pytest plugin that patches async_test_home_assistant
to create host + sandbox HA instances with real TCP websocket
- conftest.py: adds core/tests to sys.path for test infrastructure imports
- pyproject.toml: point homeassistant dep at local core checkout, add test deps
Usage: pytest -p hass_client.testing.conftest_sandbox \
../core/tests/components/input_boolean/test_init.py
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
SandboxClient connects to HA Core via a sandbox token, fetches assigned
config entries, sets up input helper integrations locally, registers
entities back to the host, pushes state changes, and subscribes to
service call forwarding.
Three e2e tests validate: token/instance creation, state updates, and
unload cleanup.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add sandbox API methods to HomeAssistantAPI for communicating with HA Core's
sandbox integration: get_entries, update_entry, register/update/remove device,
register/update/remove entity, update_state, and subscribe_service_calls.
Override __new__ on RemoteHomeAssistant to accept extra keyword arguments,
since HomeAssistant.__new__ has a strict (config_dir: str) signature that
rejects the remote_config kwarg in Python 3.14.
