I think of it as "employing occult means to bond with a spirit." Convincing the spirit to form the bond is one way to do that, but it could also be flavored as some sort of magical binding diagram thing if you think magical binding diagrams are cool.
You've mentioned the possibility of the spirit rising to Essence 4+ breaking the binding, and certainly permanent death would do it. I assume the Twilight would satisfy the "powerful patron" bit that might allow an elemental or demon to be brought back upon being slain. Would this pact be enough to achieve that (perhaps with some Willpower and/or mote cost) or would a sorcerous working or something similarly active be needed?
I think the bond alone makes sense for allowing weaker demons and elementals to reform.
Can the pact be trivially ended by the Twilight?
There's nothing in the book that I'm aware of that addresses ending your bond with a familiar of any kind. As a Storyteller, I wouldn't let it be done as a trivial thing with no narrative significance, but would let it happen if it made sense from a roleplaying perspective.
How reflexive is the reflexive summoning and banishing? Could the Twilight banish the spirit in response to the spirit having an attack declared on it, thus avoiding the attack?
I wouldn't let them banish it mid-attack.
What Survival Charms can be used on this spirit familiar? You've mentioned those that don't call out having to be used on animals, but I just want clarity on what that means. Does the Charm flavor text have to call out it being used on animals for it to be disqualified (I'm thinking about Spirit-Tied Pet, Saga Beast Virtue, and Deadly Predator Method as examples) or would the Charm only need to reference mechanics that only animals get (like command training using Bestial Traits Technique)?
Charms that specify "animal" rather than just "familiar" are incompatible with spirit familiars. Of the corebook Survival Charms, that's Spirit-Tied Pet, Beast-Mastering Behavior, and Bestial Traits Technique.
