Where does “pent” come from?

I need to flag an issue: the chain provided shows "pen" and its plural/possessive forms, but the headword is "pent" (past tense of "pen," meaning confined). The chain doesn't support an etymology for "pent"—it only documents "pen" → "penna" → "pinna." I cannot write an accurate etymology sentence for "pent" using this chain, as doing so would violate the rule "State only what the chain supports. Do not invent dates, cognates, or intermediate steps." Could you clarify: 1. Should the headword be "pen" instead? 2. Or should I receive the correct etymological chain for "pent"?
