Favour timeline — who owns each window

StageFavouredWhy
Level 1OlafShe is a bottom-tier level-1 and you are top-tier — Undertow slow into a passive-fueled auto wins first contact before she has a single poison stack.
Level 2Even / skillHer Q poke starts to sting once she has stacks, but a committed Q-slow trade still out-damages it — genuinely even as she finds range.
Level 3CassiopeiaWith W grounding online she cancels your gap-close and kites your axe to poison range — she edges this window before your 6 spike.
Levels 4-5Even / skillYou out-trade a pre-item Cassiopeia in short bursts, but her grounding plus your dependence on Ragnarok being up keeps it skill-tested.
Level 6Even / skillRagnarok ignores her R face-stun and W slow so you can dive her — but a clean flash-R or kited grounding can still deny it, so it's read-dependent.
First itemEven / skillYour Black Cleaver / Bramble all-in is oppressive with perma-slows, yet her first poison item lets her trade poke for your true damage — a coin-flip on positioning.
Two+ itemsEven / skillLiandry's and Rylai's let her perma-slow and out-DPS your flat true damage — but if you snowballed she can still be too far behind to kite you, so it stays skill.

Early game (levels 1–5)

Cassiopeia is one of the worst level-1 champions in the game and you are one of the best, so step up immediately — throw Undertow on the wave to land a slow, then walk in for a Q-slowed auto while your passive attack speed climbs. She has no poke that out-damages a committed melee trade this early, and no escape: her W grounding and R stun don't exist yet. Don't over-extend past river on her poison stacks alone, but every time she steps to last-hit, axe-slow her and punish.
