symfonic.memory.models.context

context

AssembledContext and ContextBudget models.

Deprecated: These models are no longer used by the active hydration path. Hydration is handled by SymfonicAgent._hydrate() which returns HydratedMemory. MemoryOrchestrator.hydrate_context() which produces AssembledContext is never called by anyone in the current codebase.

AssembledContext 

AssembledContext(**data: Any)

Bases: BaseModel

Fully assembled context ready for LLM consumption.

.. deprecated:: AssembledContext is deprecated. Hydration is handled by SymfonicAgent._hydrate() which returns HydratedMemory.

is_within_budget 

is_within_budget(budget: ContextBudget) -> bool

Check whether this context respects all budget constraints.

Returns True if all component counts are within the budget limits. max_memory_entries was removed in v5.6.0 (v6.0 API freeze prep); memory-entry count is no longer budget-enforced -- the live SymfonicAgent._hydrate path uses max_tokens instead.

ContextBudget 

ContextBudget(**data: Any)

Bases: BaseModel

Defines the limits for context assembly.

.. deprecated:: ContextBudget is deprecated. Budget constraints are now handled internally by SymfonicAgent._hydrate() via FrameworkConfig.
