Enum CollateralUnknownReason 

pub enum CollateralUnknownReason {
    NotCensused,
    BehindFinalityDepth,
    RecordUnreadable,
    NoChainSource,
}

Why a node cannot state this epoch’s collateral requirement.

Each variant names a DIFFERENT missing fact, because the remedies differ: a node that has not censused the epoch needs to run the census, whereas a node inside the finality depth needs only to wait for the chain to settle. Collapsing them into one “unavailable” would hand every client the same unactionable sentence.

Variants

NotCensused

This node has not censused the epoch, so it holds no record to answer from.

BehindFinalityDepth

The epoch’s census inputs are not yet final — the node is inside CENSUS_FINALITY_DEPTH_BLOCKS of the chain tip and any figure it derived could still move.

RecordUnreadable

The node holds a record for the epoch but could not read it.

NoChainSource

The node cannot see the chain at all, so it cannot know whether a record should exist.
