A field named "" loads, and a bare {} token renders it, but no dot path can
reach it — List hides it and Fake cannot ask for it. {a.} is already rejected
for the same reason, so the two spellings disagree about the same mistake.

Widening the fence used containment for both kinds of hold, which is right
for a level a path reads and wrong for a sibling a calc reads. A path may
read into anything the level contains; an operand's draw fixes only the value
it renders. So containment rejects a reference to a sibling the operand never
renders, which loads fine today and cannot disagree, and misses a reference
reaching what the operand renders through, which disagreed in 20 of 40 draws.
Also pins the repeated reference arm, the one kind that reaches the repeat
check by passing the per-arm checks rather than falling through them.

{..|..} reported a repeated arm rather than a reference with no path, and
{|} reported one rather than a missing field. Both are load errors either
way, but the repeat is a consequence of the real mistake, so the real one
should be what the author reads.

{a|a|b} skews an alternation three to one, an undocumented third way to
weight beside a choice's weight and a repeated choice entry. These pin its
rejection, and one accepted case fixes the boundary: {x}{x} is two tokens,
so it stays two independent draws.

A dot is already rejected in a category, folder or field name. The token
grammar reserves three more characters: '|' separates a token's arms, '('
opens a function call, and '}' ends the token. A name carrying one resolves
by dot path and is advertised by List, yet no format can name it.
These pin the rejection, and one accepted case fixes the boundary: ')' on
its own is spellable, so it stays legal.
