Two time scales and complete state

Every source forward invocation constructs a new zero hidden state. Hidden state is carried within the sequence, not between examples or evaluation calls.

Longitudinal state instead includes

The index $k$ denotes an intervention cycle. A checkpoint intended to continue a live recurrent sequence would additionally need its current $h$; the supplied pipeline does not do that.

Mask invariants and repair-capacity restrictions remain the coordinate bookkeeping of Psy03-B CheungPsy03B. A scar count is not a recurrent stability constant.
