The cache already declares and persists what type each member is, so numbers
cost no migration. What they do cost is a public way to read a declared value
at all, because the evaluator today cannot reach one from outside the cache,
which is why the existing snapshot loop reflects. That is a hundred and fifty
lines, not sixty, and the ledger moves the wrong way to say so.
Three claims inherited from the earlier pass were wrong and were cut rather
than designed around. A fifth selector engine turned up in Rust. And the
cache's index maps keep one key per value, so an evaluator that reached for
them would answer a query about a whole family with a single row.
Watching a selection is mapped as its own cut, where nine overloads that are
a query language in disguise collapse into one.
