- LeaseGuard gains an is_cancellation convenience property
- ActiveAssignmentRunner marks the lease lost with a cancellation
reason when a renewal response reports cancel_requested
- AssignmentExecutor threads stop_reason through to TaskRunner/
WorkflowRunner and maps a cancellation-flavored stop to
AssignmentExecutionResult.status = "cancelled" instead of "failed"
- AssignmentProcessor forwards a three-way done/cancelled/failed
status when reporting the terminal result
- Add/extend tests across lease, assignment, processor, and client
Adds host_agent/skill_sync.py (HostAgentSkillSync) which constructs the
synced + local skill stores, the Cloud API sync client, and the runner,
then drives them on the host-agent lifecycle: incremental per-host pull
into the synced catalog, fork-on-revocation, and a best-effort local-
skill inventory report to the Cloud (design D7). Wired into
create_application + run_async start/stop. Host-agent suite green
(219 passed).

create_task_runner() built TaskRunner's observer/screenshot_provider by
calling describe_screen(device_id)/take_screenshot(device_id) without
manager=, so both silently fell back to the process-global DEFAULT_MANAGER
singleton instead of the Host Agent's real, device-populated DeviceManager.
DEFAULT_MANAGER never has any device registered, so every task's first step
raised DeviceNotFoundError even though the console (which does pass
manager=) showed the same device as connected. Deterministic on every task,
independent of process count.
Add regression tests confirming both lambdas now resolve devices via the
configured manager; verified each fails with the original DeviceNotFoundError
symptom when the fix is reverted.

Acquire an exclusive, non-blocking filelock on the identity state directory
as the first action of create_application(), before resolve_host_identity()
or any enrollment/heartbeat side effect. A second process against the same
identity_path exits immediately with InstanceAlreadyRunningError naming the
lock path; the lock releases automatically on any process exit (including
SIGKILL) via OS-level advisory locking, and explicitly during run_async()'s
shutdown finally block. filelock is promoted from transitive to direct
dependency (version unchanged at 3.29.7).

Replace hand-written f-string + html.escape() rendering in the Host Agent
local console with a module-level Jinja2 Environment configured with
select_autoescape(["html","xml"]). XSS safety now holds by mechanism
rather than per-call discipline — every operator-controlled field
(device name, connection_info, task summary, etc.) is escaped by the
engine uniformly.
Eight templates under host_agent/web/templates/ replace the former
_chrome(), _CSS, escape(), and per-page _xxx_body() helpers: base.html
(header/nav/CSS + {% block body %}), login, dashboard (with the polling
<script> preserved byte-identically inside {% raw %}), devices, account,
history, tasks_list, and task_detail. The task-list and task-detail
templates — added by the just-landed task-execution-progress-visibility
change — were also migrated here rather than left in f-string form,
since this change removes the shared helpers they depended on.
URLs, auth/session/CSRF semantics, redirects, and /api/status JSON are
unchanged. 15 new template tests cover render-smoke, XSS probing, script
byte-identity, and no-autoescape-bypass guards. Tasks 8.1-8.6 (manual
browser verification) remain.

DeviceManager marks a device "busy" as soon as an Appium/WDA session is
connected, which is unrelated to whether a task is currently executing on
it. The Host Agent's local console displayed this raw status, making
connected-but-idle devices look permanently busy. Cross-reference the
device id against AgentStatusTracker's current_assignment (already
tracked via mark_assignment_started/finished) to show "connected" unless
a task is actually running on that device.
Adds an opt-in dependency supervisor inside the Host Agent that probes,
spawns, and restarts the two local processes the macOS single-machine
real-device workflow depends on: the Appium server (gates Driver.connect())
and the local Runtime API (local inspection). Default-off; gated by
HOST_AGENT_DEPENDENCY_SUPERVISOR_ENABLED plus per-dependency *_SUPERVISED
flags.
Mitigates the live-incident failure mode where forgetting to start Appium
silently keeps devices offline and tasks queued forever with no error
surfaced in Host Agent logs.
Behavior (per openspec change):
- Adopt-don't-fight: probe (TCP + dependency-specific HTTP health check)
before spawn. Healthy listener → adopted (never killed/restarted).
Unhealthy listener → port-conflict error, skip. No listener → spawn.
- Only supervisor-spawned processes are restarted on crash, with capped
exponential backoff (1s/2s/4s/8s, capped at 30s) and a per-process-lifetime
attempt ceiling (HOST_AGENT_DEPENDENCY_RESTART_MAX_ATTEMPTS, default 5).
- Spawn failures (e.g. missing executable) logged distinctly from crashes.
- Graceful stop terminates only spawned children; adopted processes untouched.
- Supervisor starts before the heartbeat loop's first connect_devices() pass
and stops alongside existing heartbeat/console teardown.
Validation: ruff check + format clean, compileall clean, openspec validate
--strict valid. Non-integration suite 503 passed / 44 deselected / 2 failed
(both failures pre-existing from unrelated 03c7c30 LLM_PROVIDER_ENC_KEY;
verified by stashing this change). macOS real-device manual verification
(task 6.4) deferred to a macOS host.

Implements all 19 tasks of the cloud-planner-proxy OpenSpec change:
- Cloud API: cloud.planner_config (CloudPlannerConfig, load/build helpers)
reusing runtime.tool_calling_client provider clients (no new dependency
needed -- device-cloud-platform already depends on device-agent-runtime).
- Cloud API: new host-scoped POST /internal/v1/hosts/{host_id}/planner/decide
internal endpoint, reusing existing bearer auth; logs only metadata
(host id, tool name, latency, error class), never prompt/screenshot
content.
- Host Agent: new AI_PLANNER_TRANSPORT config (direct default | cloud) and
host_agent/cloud_planner_client.py::CloudProxyToolCallingClient, a
synchronous ToolCallingClient implementation (structural, not importing
runtime) that calls the new endpoint via its own httpx.Client -- avoids
bridging the async HostAgentClient across the worker-thread boundary
that AIPlanner.plan() runs in (asyncio.to_thread in lease.py).
- Host Agent wiring: create_execution_factories()/_host_agent_planner()
select the cloud-proxy client only when AI_PLANNER_TRANSPORT=cloud;
direct/unset transport is unchanged (still the default).
- Tests: 22 new tests across Cloud API config, the new endpoint, the new
client, and transport-selection wiring; full non-integration suite
(492 tests) passes with no regressions.
- Docs: docs/CLOUD_DEPLOYMENT.md documents the cloud transport, its
trade-offs, and the credential split between Host Agent and Cloud API.
proposal.md/design.md were corrected during implementation to reflect two
findings: no new anthropic/openai dependency is actually needed, and
CloudProxyToolCallingClient uses its own sync httpx.Client rather than a
new HostAgentClient method, per the thread-boundary reasoning above.
- Host Agent now defaults AI_PLANNER_ENABLED=true (opt-out via env),
scoped to apps/device-host-agent/host_agent/execution.py only; the
shared runtime.planner_config default (disabled) is unchanged.
- Add openspec proposal for cloud-planner-proxy: centralize LLM
provider config/credentials on the Cloud Control Plane and let the
Host Agent proxy AI Planner decisions through it instead of holding
provider API keys locally. Proposal only, no implementation yet.
Host Agent:
- One-time local operator account bootstrap (PBKDF2-HMAC-SHA256, atomic
0600-permission write) gating the daemon's first unattended start via a
new `setup` CLI subcommand.
- Default control-plane URL now https://amcp.home.jerryyan.top (env var
override unchanged).
- Enrollment no longer requires a pre-issued token; falls back to
zero-token self-service enrollment when none is configured.
Cloud control plane:
- CLOUD_SELF_SERVICE_ENROLLMENT_ENABLED (default false) opt-in flag.
- SelfServiceEnrollmentAuthProvider + ChainedEnrollmentAuthProvider:
configured tokens still take priority; self-service only applies when
no token matches, preserving edge-host-enrollment's token-bound path.
- Fixed a latent bug in sql_repository.py::enroll_host: the token-conflict
lookup used `== enrollment_token_digest`, which SQLAlchemy compiles to
`IS NULL` when the value is None, so every self-service enrollment after
the first would have falsely collided with an existing NULL-digest host.
Skipped that lookup entirely when the digest is None.
Docs/deploy: .env.example, compose.yaml, compose.deploy.yaml,
CLOUD_DEPLOYMENT.md, MACOS_IPHONE_SETUP.md updated for the new flag,
URL default, and required `device-host-agent setup` step.
Verification: 494 non-integration tests pass; openspec validate --strict
passes. PostgreSQL-backed contract tests and full manual end-to-end
verification were not run (no Postgres/Docker or reachable cloud-api in
this environment); noted as unchecked in tasks.md 7.2/7.4.
