Proof step 7 from proof alter-observe-respects-policy (previous step)

observe(domvar0, nam, ag) ⊦ domvar0 = User, domvar0 = User->User_Airline, domvar0 = Abort9, (nam ≠ state(`state2') ∨ ¬ exTravelPlanner(ag)) ∧ (nam ≠ Mailbox(ReleaseCCD-CreditCardCenterCmd) ∨ ¬ exCreditCardCenter(ag)) ∧ (nam ≠ locVar(`airline') ∨ ¬ exCreditCardCenter(ag)) ∧ (nam ≠ Mailbox(ConfirmRelease-UserCmd-3) ∨ ¬ exUser(ag)) ∧ (nam ≠ Mailbox(GetDeclassifiedCCD-CreditCardCenterCmd) ∨ ¬ exCreditCardCenter(ag)) ∧ (nam ≠ state(`state3') ∨ ¬ exCreditCardCenter(ag)) ∧ (nam ≠ locVar(`ccd') ∨ ¬ exUser(ag)) ∧ (nam ≠ locVar(`airline') ∨ ¬ exUser(ag)) ∧ (nam ≠ User-ConfirmRelease(`3') ∨ ¬ exUser(ag)) ∧ (nam ≠ User-ConfirmRelease-count(`3') ∨ ¬ exUser(ag)) ∧ (nam ≠ User-ConfirmedRelease-count(`3') ∨ ¬ exUser(ag)) ∧ (nam ≠ state(`pre9') ∨ ¬ exUser(ag))

User applied rule constructor cut

And obtained the following new goals

Proof step 2:
domvar0 = User_Airline, observe(domvar0, nam, ag) ⊦ domvar0 = User, domvar0 = User->User_Airline, domvar0 = Abort9, (nam ≠ state(`state2') ∨ ¬ exTravelPlanner(ag)) ∧ (nam ≠ Mailbox(ReleaseCCD-CreditCardCenterCmd) ∨ ¬ exCreditCardCenter(ag)) ∧ (nam ≠ locVar(`airline') ∨ ¬ exCreditCardCenter(ag)) ∧ (nam ≠ Mailbox(ConfirmRelease-UserCmd-3) ∨ ¬ exUser(ag)) ∧ (nam ≠ Mailbox(GetDeclassifiedCCD-CreditCardCenterCmd) ∨ ¬ exCreditCardCenter(ag)) ∧ (nam ≠ state(`state3') ∨ ¬ exCreditCardCenter(ag)) ∧ (nam ≠ locVar(`ccd') ∨ ¬ exUser(ag)) ∧ (nam ≠ locVar(`airline') ∨ ¬ exUser(ag)) ∧ (nam ≠ User-ConfirmRelease(`3') ∨ ¬ exUser(ag)) ∧ (nam ≠ User-ConfirmRelease-count(`3') ∨ ¬ exUser(ag)) ∧ (nam ≠ User-ConfirmedRelease-count(`3') ∨ ¬ exUser(ag)) ∧ (nam ≠ state(`pre9') ∨ ¬ exUser(ag))
