Won the battle but no summon?

Leviathan: finish Nichol’s Duty; the Chapter 3 story battle is not its recruitment reward.
Odin: complete the final Old Man conversation after the Shadow battle.
Carbuncle: return to the epitaph after finding all three fragments.
Bahamut: check the other eight summons and Chapter 7 progression before repeating the airship interaction.

Plan a detour before leaving

Equip the relevant weakness command, carry recovery and save before starting an optional trial. If the trial overwhelms your current party, return after equipment or ability improvements. An optional summon is not automatically the next main-story gate.
