OptionalregardRegard realm: the viewer's signed attitude toward the referent
(-100..+100; absent or 0 = no opinion). A value, not a flag —
a planned divergence under the payload rule, exactly as knownAs is a
value on the spine. Unlike knownAs's raise-only coalesce, know
overwrites this on set: the delta arithmetic + range clamp live in
the consumer (RegardApi/RegardLogic), never in the store.
OptionaltypeIdentification realm: the viewer knows what kind of thing the referent is. Binary in v1 (unidentified ↔ identified); partial levels defer. Read the actual type name live; this is just the gate.
The thin, axis-specific payload riding on a BeliefRecord.
Payload rule (the slate's): flag by default, value only for planned divergence.
knownAsis a value on the record spine because faking / nicknames are planned divergences from the live name. The identification realm stores atypeKnownflag — the known type name is read live off the referent, never snapshotted. Do not snapshot referent state into the payload.
