I'm not sure how gentle correction applies when I'm quoting from the Magic Overview...?
There was a list of spells in my post, I'm certain.
That list contained spells which had pertinent decisions
not made at the time the spell came into effect.
That's how it applies.

However, something else jumped out at me: the effect of a spell isn't necessarily the triggering condition. Let's look back at
scorching ray.
Effect: ray.
The wizard can use the ray to make an attack, but the attack isn't actually an effect of the spell -- it's merely the use of the spell's effect. In this case, I'd posit that the spell effect must exist before it can be used for an attack -- and there's the interval where the PC's readied action ("run when attacked") could go off -- because the attack isn't strictly part of the spell.
In the case of
fireball, note that the same principle could apply, thanks to this bit: "If you attempt to send the bead through a narrow passage, such as through an arrow slit, you must 'hit' the opening with a ranged touch attack, or else the bead strikes the barrier and detonates prematurely."
This argument doesn't generally apply to area effects, so I don't like it, but I'll take it as a freestanding support.
