get(), relate() and update() each carried a "very large metadata" case that
parked an array of 1000 (or 100) elements in the metadata bag and asserted it
came back. The indexable-array bound refuses that shape at the write door now
— an array field mints one posting per element, so an unbounded array is an
unbounded write — and the three cases were failing on the refusal they should
have been pinning.
Each is rewritten to the law that replaced it, in two halves:
- a large SCALAR payload still round-trips whole through the door: a
10,000-character string, 100 sibling fields, a ten-deep nest walked to the
bottom, and an array sitting exactly ON the bound, checked first element
to last;
- an array one element OVER the bound refuses with MetadataArrayTooLargeError
carrying the field, the length and the bound, on the error object AND in
the message. update()'s refusal additionally proves the row is unchanged,
and relate()'s that no relation was written — refused means not written,
not written-then-skipped.
Every length is derived from the imported MAX_INDEXED_ARRAY_LENGTH; none is
typed as a number. That is what made the old cases fragile: 100 read as "over
the bound" and 1000 as "large", and both meanings changed under them when the
constant moved. These follow the constant instead.
