Are the targets of spells that resolved earlier in the turn public knowledge that opponents must reveal if asked?

Ruling: Targets of spells that have resolved earlier in the turn are not public knowledge. Opponents are not required to tell you what a spell targeted after it has resolved.

Nuances:

• You must answer what spells/abilities resolved this turn and where they were played from
• If a spell created ongoing effects still visible in the game state (like a unit still affected by Cleave), that current game state information is public
• If the targeted unit is no longer on board or the effect is no longer visible, you don't have to reveal what was targeted
• The rules specify "play choices made for them" are public while spells are on the Chain, but this information is no longer public after resolution
• Players cannot misrepresent derived information, but also cannot be compelled to provide it
