docs/SIM.md §2: the countdown (attackCountdown, 1e-9 like timeLeft / buffs / every()), 1 s = 30 ticks and 3 s = 90, the
双眼皮 turrets and 寒檀's icicles on it, the drones that compared with 1e-9 already, the count-up content clocks not
covered; the official note — PRTS 作战机制/sandbox 「帧对齐机制对攻速的影响」: one frame = 1/30 s, since 2019-12-24 a
non-integer frame count is rounded (四舍五入; before, 进一取整), an exact one stays; here a non-integer count still ends on
the tick that crosses 0 (⌈30 × interval⌉: 1.25 s = 38, 能天使's 0.678 s 21 against the official 20) — an older
difference, unchanged. §7.1: SP within 1e-9 of the cost is the cost (gainSp, _normalize). design/geometry-time.md §4:
the engine's timer tolerance in one place. history/0.2.2.md §27.61 (Seen / Official / Now / Golden with the end-result
flips one line each / Tests / Docs) and the area map's "→ §27.61". docs-consistency + docs-paths: 31 pass.
