Modules

render

Rendering abstraction layer for service projections.

Structs

ActionDef

A business operation schema describing what an action does and what it needs.

FieldDef

A field definition within a service projection.

FieldMetadata

Metadata for a single model field.

GuardDef

A named boolean condition that guards action execution or state transitions.

InputDef

An input parameter definition for an action.

IntentScore

A scored intent with confidence and the structural signals that contributed.

ModelMetadata

Intermediate representation of a model for ServiceDef derivation.

RelationshipDef

A service-to-service relationship declaration.

ServiceDef

A service definition describing a domain entity and its fields.

StateDef

A state within a state machine.

StateMachine

A state machine schema describing lifecycle states and transitions.

TenantColumn

Tenant-scope predicate slot. Phase 241 leaves this None on every plan; Phase 242 fills it (column name only — the runtime tenant_id is injected by the executor from the dispatch_write tenant_id parameter, never stored here).

Transition

A transition between two states, triggered by an event.

TransitionPlan

A serializable description of a state-transition write, derived from the declared StateMachine + ActionDef.

Enums

Cardinality

Structural cardinality of a service-to-service relationship.

CrudPlan

A pure, serializable CRUD write plan — the data-only analog of TransitionPlan.

CrudVerb

The three generic CRUD write verbs derived from a projection’s opt-in flags.

DataType

Abstract data type categories for service fields.

Error

FieldMeaning

Semantic meaning of a field, driving rendering and behavior decisions.

Intent

Structurally-derivable intent classification for a service.

IntentHint

Manual override for intent derivation when structural analysis is wrong.

NavigationHint

Presentational hint for how a relationship should be rendered in UI.

RenderHint

Non-visual rendering hint for URL/ImageUrl fields.

Warning

Structural warnings from service and state machine validation.

Functions

derive_crud_plan

Derives a pure CrudPlan for verb from the service declaration and agent inputs.

derive_intents

Derives ranked intents from a ServiceDef’s structural signals.

derive_transition_plan

Derives the TransitionPlan for action_name from the service’s declared state machine.

infer_meaning

Infers a FieldMeaning from a field name using common naming conventions.
