paddlepaddle has no Python 3.14 (cp314) wheel on PyPI, so host-agent
deployments on 3.14 can never install it, causing OCR to fail at
runtime with RuntimeError. Pin the workspace to Python 3.13 across
all pyproject.toml files, the Docker base image, and the Jenkins CI
image; regenerate uv.lock against 3.13.
Also fixes a pre-existing Python-2-style `except X, Y:` syntax error
(invalid in all Python 3.x) in runtime/task.py and
packages/cloud-platform/cloud/{sql_repository,internal_api/api}.py,
introduced in 22d37ca9 and unrelated to this change's scope, which
blocked the full test suite from collecting on any interpreter
version.
openspec change: downgrade-python-3-13-paddleocr
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.
