[0.1.3] - 2026-06-06

Task — new domain entity representing a concrete work item in a Scope's backlog. Fields: id, title, description, priority (TaskPriority), kind (TaskKind), lifecycle_status (TaskLifecycleStatus), on_hold, estimated_duration (timedelta | None), actual_duration (timedelta | None), related_acs (frozenset[str]).
TaskPriority enum — low, medium, high, critical.
TaskKind enum — enhancement, bug, research, investigation, documentation, release, deployment.
TaskLifecycleStatus enum — pending, doing, validation, done.
Scope.backlog — frozenset[Task] field holding the scope's work items. Task ids must be unique within the backlog. Backlog merges across the scope hierarchy the same way user_stories does.
estimated_duration is mandatory for kinds enhancement, bug, documentation, release, and deployment; optional for research and investigation.
related_acs merges as a union (same semantics as UserStory.tags).

AcceptanceCriterion.requirement_specification — optional ISO 29148 document type (RequirementSpecification | None, defaults to None). Accepted values: SRS, SyRS, StRS.
AcceptanceCriterion.requirement_group — optional requirement category within the chosen specification (RequirementGroup | None, defaults to None). Must be set together with requirement_specification and must be a group that belongs to that specification.
RequirementSpecification and RequirementGroup enums — now part of the public API, importable directly from fushinryu_model.

UserStory.dod — optional free-form prose field for the definition of done (str | None, defaults to None).
UserStory.tags — unordered set of short label strings (frozenset[str], defaults to empty). Tags merge as a union when parent and child stories are merged.
AcceptanceCriterion.tags — same type and merge semantics as UserStory.tags.

Scope.description is now optional (str | None, defaults to None). Previously it was a required field.
Project renamed from fushinryu_model to fushinryu-model to align with PyPI distribution naming conventions. The importable package name remains fushinryu_model.

Initial release. Provides the core domain entities:

Scope — organisational unit with DAG parent hierarchy and collapse().
UserStory — structured requirement with who / what / why and UserStoryType.
AcceptanceCriterion — Given / When / Then testable condition.
ManualValidation / AutomatedValidation — immutable validation evidence.
Merge semantics for all entities via pleroma.MergeableModel.
