In Wolfgang Schwartz proof there is no P(t). In his syntax 
one would write Pt. Because his FOL is based on single letter 
predicates, variables, functions, only. Parenthesis and commas

are optional. So Lt and Dt is not the same as in DC Proof. It 
means L(t) and D(t). So this here proofs a FOL formula it does
not need P(t). Why do you need P(t) in DC Proof?

((Dt → Lt) ∧ ¬Lt) → ¬Dt is valid
https://www.umsu.de/trees/#((Dt~5Lt)~1~3Lt)~5~3Dt

You can also proof the rain example. Using N(t) to denote
some time later, the „next“ operator of a temporal logic:

((Rt → UN(t)) ∧ ((UN(t) → ¬WN(N(t))) ∧ (¬Rt → ¬WN(N(t))))) → ¬WN(N(t)) is valid.
https://www.umsu.de/trees/#(Rt~5UN(t))~1(UN(t)~5~3WN(N(t)))~1(~3Rt~5~3WN(N(t)))~5~3WN(N(t))
