symfonic.agent.cutover.default_admission

default_admission

The stock configuration capabilities that still need explicit composition.

FrameworkConfig enables these capabilities by default, while the kernel may serve each only when the composition root supplied its operative ports. Keeping the rows here makes the retirement question executable: a default is not "migrated" because it has a flag or a compatibility fallback, but only when its bundle predicate is true and its listed kernel behaviour is tested.

DefaultAdmissionRow dataclass 

DefaultAdmissionRow(field: str, capability: str, bundle_predicate: str, kernel_effect: str, evidence: str, fallback_metric: str = 'kernel_fallback.v1')

One stock-on capability and the evidence needed to admit its turn.

is_served_by 

is_served_by(bundle: Any) -> bool

Return whether this exact composition can serve the stock capability.

    """Return whether this exact composition can serve the stock capability."""
    predicate = getattr(bundle, self.bundle_predicate, None)
    return callable(predicate) and bool(predicate())

unmet_default_admission_rows 

unmet_default_admission_rows(config: Any, bundle: Any) -> tuple[DefaultAdmissionRow, ...]

List every enabled stock capability this composition cannot serve.

The live envelope returns its first refusal. This inventory evaluates each independent default row, so a hydration refusal cannot hide missing consolidation or routing evidence in a stock deployment.
