pub const SHARE_LIMIT_PERCENT: u64 = 10;Expand description
A ping whose uncached input, or (after ping 1) whose cache write, exceeds this share of the prefix ends the period: it is paying for uncached tokens or rewriting history, not refreshing a cache. 10%: the trailing ping message is ~40 tokens, under 4% of the smallest cacheable prefix (1,024 tokens), so a healthy ping never comes close.
