A senior engineer is writing a postmortem and wants to emphasise an absolute prohibition. Which sentence uses inversion correctly?
Fronted negative + inversion: When a negative adverbial phrase such as under no circumstances is moved to the front of a sentence for emphasis, the subject and auxiliary verb must invert: should passwords be, not passwords should be. This structure is common in formal technical documentation, security policies, and compliance language to stress an absolute requirement.

A tech lead wants to highlight an unexpected combination of problems in a status update. Which sentence applies "not only … but also" inversion correctly?
"Not only … but also" inversion: After not only at the start of a clause, auxiliary-subject inversion is required: did the deployment fail, not the deployment failed. The second clause introduced by but also keeps normal word order. This structure adds rhetorical force to incident reports and executive summaries.

An SRE is documenting a rare error condition. Which sentence uses "rarely" inversion correctly?
Fronted frequency adverb inversion: Negative or restrictive frequency adverbs such as rarely, seldom, and never trigger subject-auxiliary inversion when placed at the start of a clause: Rarely is this error…. This construction is used in technical documentation and runbooks to signal that a condition is exceptional, drawing the reader's attention.

An architect is writing an RFC and wants to say that only with proper caching can performance targets be met. Which sentence is correct?
"Only + prepositional phrase" inversion: When only followed by a prepositional phrase opens a sentence, inversion applies: can performance targets be met. This pattern appears in RFCs and design documents to assert a condition as the sole path to a result, making the dependency unmistakably clear to reviewers.

A compliance engineer writes: "We have never encountered such a widespread data-loss event — ___." Which inversion completes the sentence most naturally?
"Nor" inversion:Nor used as a connector between two negative clauses requires auxiliary-subject inversion in the second clause: nor have we seen. This adds parallel emphasis and is a hallmark of formal incident reports, audit letters, and compliance communications. The normal-order alternatives (B, C, D) are grammatically incorrect after nor.
