FLATPACK_LAZY_LIMIT=0 is documented in the config file as "parse everything up front", but it stopped flatpack:build:

Compiling content ... FAIL
TypeError: Unsupported operand types: array + null
at src/LeanYaml.php:34

Cause

A field is set aside to be parsed later when its size is over the limit. With a limit of zero every field is over it, the id and title included. Nothing was left to parse up front, the parser returned nothing, and the next line added an array to it.

So zero did the opposite of what the comment says. It has been like this since 1.0; the default of 2048 never reaches it.

Fix

Flatpack::configure() treats a limit of zero or less as no limit, which is the one place both checks read it from (Shallow::split() for files, EntryCodec for cached entries).

Checked

On the demo's 9,780-entry site with Statamic 6.41.0:

FLATPACK_LAZY_LIMIT	Before	After
0	build fails	builds in 21 s and 779 MB, everything parsed
2048 (default)	14 s, 255 MB	unchanged

Every entry and term URL matches Statamic's own Stache in both cases (12,840 compared). The parity suite passes on Statamic 6.

Reproduced on 6.40.0 and 6.41.0, so it isn't tied to a Statamic version.
