// BOSS_HIT tickers ("{0}博士对敌方领袖造成的伤害超过20% / 50% / 80%!", activity_table autoChessData.broadcastList
// comment_boss_hit_1..3, paramList 0.2 / 0.5 / 0.8) — player report after 0.1.0: "隐藏boss还没打就出了造成50%伤害播报".
//
// Reproduced with real bot matches (real sim) that reach the 隐秘核心: the Hidden Core's very first hit (a few dozen
// HP of a 900000 pool) already announced "超过50%". The ticker divided the player's damage of the WHOLE match
// (stats.bossDamage, Final Assault + Hidden Core: the result screen's 领袖伤害) by the hidden leader's pool, so the
// Final Assault's damage counted as damage to the hidden leader. The share is now the player's damage to the current
// leader's pool (SharedBossPool.byPlayer, one pool per boss round) over that pool: each boss round announces its own
// 20 / 50 / 80 % — on server-run fields, under client-side combat and after a server takeover alike. (The browser's
// strip also played a Final Assault line late, into the Hidden Core: test/ui/bosshit-ticker.test.js.)
