feedback5 CB4: 自制投石机's targeting ignores its block (索敌不受阻挡影响) — blocked by an operator on the 排气格栅 with nobody else in range it does not attack, as in the official game (community report of 2026-10-06, item 24)

The 「投石车」 is 自制投石机 (enemy_10162_mnctpt), the 「蒸汽地板」 the 排气格栅 smog (隐匿 to enemy ranged attacks). PRTS
天赋 「索敌不受阻挡影响」: the blocker exception (a blocked enemy attacks its blocker whatever its selectability) does not
apply to it. New enemy profile field `blockFree` (spawns.js): attackTargets selects as if unblocked, canTargetAlly
refuses a 隐匿 / 迷彩 blocker to it, sortAllyTargets puts no blocker first. Other enemies unchanged.

Golden: standin-06 (the bounty catapult, blocked by 忍冬, now shoots by 仇恨值 — checked instrumented).
Tests: test/sim/feedback5-catapult-smog.test.js (3; 2 fail on the parent). Docs: DESIGN §25.18.7, docs/SIM.md.
