Workplan

Workplan response model. OpenAPI title is ``Workplan``; the Python class name stays ``BlueprintResponse``.

Field	Type	Description
`id`required	`string (uuid)`	Workplan UUID
`template_id`required	`string (uuid)`	Source template UUID (workstream_id in DB)
`name`required	`string`	Workplan name
`client_id`	`string (uuid) \| null`	Client UUID (optional)
`client_name`	`string \| null`	Client name
`run_mode`	`WorkplanRunMode`	The WorkPlan's effective run posture (S2-READ §1a). ``effective`` resolves: plan-level ``configuration.run_mode`` → the workstream default → ``propose``. ``source`` tells the FE whether the value was set on this plan or inherited. ``locked`` is the firm-lock governance flag — always ``False`` in S2. show nested WorkplanRunMode
`cohort`	`WorkplanCohort`	Structural facts about the WorkPlan's bound client set (S2-READ §1b). Live exception/ready counts live on the roster's ``summary`` (one authoritative source); this object carries only the cohort's size + shape. With no multi-client cohort writer yet, ``total_clients`` resolves to 0/1 and ``selector_kind`` to ``single`` — the shape is frozen, the populating data is S2-write BE work behind it. show nested WorkplanCohort
`config_overrides`	`object`	Configuration (from DB) show nested Empty object.
`effective_config`	`object`	Merged effective config show nested Empty object.
`schedule`	`string \| null`	Cron schedule expression (from configuration; null = unscheduled)
`schedule_timezone`	`string`	IANA timezone for the schedule (from configuration; defaults UTC)
`max_duration_minutes`	`integer \| null`	Per-instance duration guardrail in minutes (from configuration; null = unset)
`human_checkpoints`	`any[]`	Sign-off gate checkpoints (from configuration). Non-empty means a partner sign-off gate is on.
`status`required	`"draft" \| "active" \| "paused" \| "archived"`	Status for workstream entities. `draftactivepausedarchived`
`last_run_at`	`string (date-time) \| null`	Most recent cycle start for this WorkPlan (null if never run)
`next_run_at`	`string (date-time) \| null`	Next scheduled execution — computed; see GET /workplans/{id}/next-run (P1)
`created_by`	`string (uuid) \| null`	Creator user ID (owner_id in DB)
`created_at`required	`string (date-time)`	Creation timestamp
`updated_at`required	`string (date-time)`	Last update timestamp
