pub const EVENT_LINE_THRESHOLD: usize = 400;Expand description
Per-event wire-line ceiling for chunking decisions. Empirically chosen
(sister 260520-pzs findings): the Monitor truncates stdout lines at
~500 chars; 400 leaves ~25% headroom for envelope overhead and char-vs-token
skew. Lines at or under this emit unchanged (zero behavior change for ~95%
of traffic). Copied verbatim.
