Wrong!
After fronted "Only after," the main clause uses inversion, so "did she realise" is correct.
3Not until the audit was complete ............... clear.
Wrong!
After fronted "Not until," the main clause uses inversion, so "did the scale of the error become" is correct.
4Rarely ............... such a convincing performance.
Wrong!
After sentence-initial "Rarely," use inversion, so "have I seen" is correct.
5No sooner ............... than the emergency generator started.
Wrong!
The fixed pattern is "No sooner had... than," so "had the lights gone out" is correct.
6Under no circumstances ............... permitted to disclose confidential data.
Wrong!
After fronted "Under no circumstances," use inversion, so "are employees" is correct.
7Little ............... that the plan would collapse so quickly.
Wrong!
Sentence-initial "Little" meaning "not at all" takes inversion, so "did he suspect" is correct.
8Only when the final results arrived ............... to improve.
Wrong!
After fronted "Only when," the main clause uses inversion, so "did the data begin" is correct.
9Seldom ............... so much public debate.

10Not only ............... his statement, but he also apologised publicly.

After fronted "Not only," use inversion in that clause, so "did the witness retract" is correct.
11So intricate ............... that even the engineers struggled to explain it.
Wrong!
After fronted "So" plus an adjective, formal English can use inversion, so "was the mechanism" is correct.
12............... the merger to fail, thousands of jobs would be at risk.
Wrong!
Formal conditional inversion uses "Were" instead of "If the merger were," so "Were" is correct.
