scheduler_task_update.py DOX

Purpose

Own the scheduler_task_update.py API endpoint.
This module handles scheduler task update requests.
Keep this file-level DOX profile synchronized with scheduler_task_update.py because this directory is intentionally flat.

scheduler_task_update.py owns the runtime implementation.
scheduler_task_update.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
Classes:
SchedulerTaskUpdate (ApiHandler)
- async process(self, input: Input, request: Request) -> Output

HTTP handlers must derive from helpers.api.ApiHandler; WebSocket handlers must derive from helpers.ws.WsHandler.
Update this file whenever request payloads, authentication or CSRF requirements, response shapes, route side effects, or WebSocket event contracts change.
SchedulerTaskUpdate is an ApiHandler.
SchedulerTaskUpdate defines process(...).
Observed side-effect areas: settings/state persistence, secret handling, scheduler state.
Imported dependency areas include: helpers.api, helpers.localization, helpers.task_scheduler.

Important called helpers/classes observed in the source: scheduler.get_task_by_uuid, serialize_task, Localization.get.set_timezone, scheduler.reload, TaskState, scheduler.update_task, parse_task_schedule, parse_task_plan.
Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Preserve authentication, CSRF, loopback, and API-key checks unless the endpoint contract explicitly changes.
Update frontend callers, plugin callers, and tests together when payload shape changes.
Use helpers.api.Response for non-JSON responses, files, redirects, or status-specific replies.

Run endpoint-specific or API/WebSocket tests for changed behavior; smoke-test browser callers when no focused test exists.
No direct test reference was found by name search; choose the nearest behavioral test or perform a focused smoke check.

No child DOX files.
