Use auxiliary-before-subject order after negative or limiting fronted expressions and in formal emphasis.
Negative / limiting opener
(Never, Rarely, Only then, Not until...)
↓
Pull the helper before the subject
helper = small verb carrying tense: have/do/did/will...
subject = who/what the clause is about
↓
opener + helper + subject + main verb
Never have I seen such a quiet office.
Rarely do we get a second chance.
Only then did I understand the real problem.
No pull:
Yesterday we signed the contract.
Only Maria knew the password.
After a negative or limiting opener, switch to helper + subject; ordinary fronted phrases do not cause this switch.
