When playing Meditation on a unit, does the Irelia Legend ability trigger to ready that unit after it's exhausted as a cost?

Ruling: Meditation does not trigger Irelia, Blade Dancer's legend ability because Meditation does not target - the unit is chosen as a cost, not targeted. Irelia's ability only triggers when a unit is targeted ("choose" in current Riftbound templating means targeting).

Sequence:

• Step 2 of finalizing: Choose the unit for Meditation
• Step 4 of finalizing: Pay the cost by exhausting the chosen unit
• Since no targeting occurred, Irelia's ability does not trigger

Nuances:

• "Choose" in current Riftbound wording indicates targeting, which is acknowledged as unfortunate templating
• Irelia's exhaust cost is formatted as "do X to do Y" (a cost within an instruction), making it not an optional additional cost
• Purple Ezreal does not reduce Irelia's costs because they are not optional additional costs
• Optional additional costs are templated like "as an additional cost to play this, you may..." (examples: Accelerate, Repeat)
• Deflect costs are mandatory, but triggered abilities with mandatory additional costs can be declined (causing them to fail finalization) - this doesn't make Deflect itself optional
