the scoped digest remembers what it read out, and a confirm keeps its action's id (V-623)

Two ecosystem defects, both of the shape where a call reports done and
nothing of the sort happened.

entityAttentionCapability surfaced every item it spoke and remembered none
of them, so the previous digest stayed the positional memory. A follow-up
"отметь второй как сделанное" then indexed into a list he had not just
heard and transitioned somebody else's item, which is the exact harm the
position resolver exists to prevent.

A parked Hexis confirm did not carry the correlation id of the action that
proposed it. The confirm lands on a later turn with a context of its own,
so the execution recorded a fresh id and an empty causation: the resolve,
the discovery and the thing they authorised sat in the trace as three
unrelated calls. The contract mints one id per action.
