- **Note**: completed
A "chunk" is any preprocessed segment ending at a `}T` (every Hayes test
is one chunk, plus the small declaration blocks between tests).
The runner catches raised errors at chunk boundaries so one bad chunk
does not abort the rest. `error` covers chunks that raised; `fail`
covers tests whose `->` / `}T` comparison mismatched.
### Chunk cap
`conformance.sh` processes the first `$MAX_CHUNKS` chunks (default
**590**). Past that, `core.fr` ships tests that rely on unsigned
integer wrap-around (e.g. `COUNT-BITS` using `BEGIN DUP WHILE … 2*
REPEAT`), which never terminates on our bignum-based interpreter. The
cap should rise as those tests unblock — run with `MAX_CHUNKS=639
./conformance.sh` once they do.
