Research direction

Search the repository for ParseError.canonicalizationError and inspect its definition, match arms, and documentation references. Rename the symbol to duplicateKeyError or duplicateKey consistently, then verify that no old references remain and the existing checks pass.

Written by the indexing model from the issue text.

Description

Problem

ParseError.canonicalizationError is the error returned when rejectDuplicates finds a duplicate key. The name canonicalizationError is vague and misleading — canonicalization normally means normalization to a canonical form, not rejection.

Expected fix

Rename to ParseError.duplicateKeyError (or duplicateKey) for clarity. Update all match arms and documentation.
