max
Exact satisfier size for a time lock spend.
Three contributors, all deterministic for this contract:
Schnorr sig push: 64 B sig + 1 B sighash + 1 B push opcode = 66
Template push: 1 B push opcode + template.size (7) = 8
Constraint push: 1 B push opcode + constraint.size (34) = 35 Total: 109 bytes per input, every spend.
Computed (rather than hard-coded as 109) so it self-adjusts if the template script or constraint ever change shape.
