Where does “perceiver” come from?

I need to flag an issue: the provided chain doesn't support "perceiver" as a valid etymology. The chain traces back through Latin "capio" (to seize/take) and PIE "keh₂p-" (to seize), which would give us "perceive" (from Latin "percipere" = to seize/grasp). However, "perceiver" is the agent noun formed from "perceive" in English, and the chain provided doesn't actually include the formation of the agent noun "-er" suffix or explain how we get from "perceive" to "perceiver." Additionally, the chain contains anomalies (Chinese 兒 appearing in a Latin-based etymology, duplicate "Latin -are" entries) that suggest data corruption. **I cannot write an accurate one-sentence origin summary without a valid complete chain.** Could you provide the correct etymological chain for "perceiver"
