What ResClean looks for

Twenty-four checks across six families. Every one runs only on the columns you approve in the next step, and every flag is written into the export with the evidence that triggered it.

Straightlining & patterning — flat grids, zig-zags, staircases, repeating cycles
AI-written verbatims — assistant phrasing, essay connectives, metronomic sentences
Speeders — total LOI, seconds per question, per-page timers
Attention checks — trap items with an expected answer
Open-end quality — gibberish, AI-style prose, filler, off-topic
Duplicates — duplicate IDs, near-identical answer vectors, copied verbatims
Batch entrants — sessions started inside one short window
Click farming — repeat IPs, subnet clusters, device + duration signatures
Response style — extreme, midpoint, acquiescent, reverse-item contradictions
