The registry grows the state-level read ladder the persisted cache builds
on: checkpoint(session) snapshots every unit's {stateVersion, observedSeq,
state} row from the watermark cache; restoreFloor(checkpoint) anchors the
tail read one event below the lowest usable watermark (so a shrunk log is
provable); restore(checkpoint, events, baseSeq) refolds each unit from its
usable row (or from init over a full read), rejects rows a tail read cannot
fix (version mismatch / overreach with baseSeq > 0 => re-read from 0), and
returns both the snapshot and the refreshed rows for durable write-back.
ProjectionCheckpointRow/ProjectionCheckpoint are the persisted-row types
minus the record keys.
