Consonance only on the ending, not a buried stress

meticulous (me-TIC-ulous, IH-K under -ulous) was consonance-rhyming
quick. Consonance now fires only when the stressed vowel is within one
syllable of the word end — people/sleep still rhymes, meticulous/quick
doesn't. Gated the projection side too, so a long-rime group stops
advertising a misleading stressed-syllable consonance.
