Despite these careful advances, the tool's story threaded through the thorny spaces where automation meets human judgment. An elder archivist wrote a long letter that arrived in the project mailing list, full of gentle admonitions. They recounted a time when a municipal registry normalized names in a way that erased diacritics and collapsed distinct surnames into a single canonical form; genealogists lost a nuance that only a living memory could have corrected. The archivist’s plea was precise: tools must preserve the undoable. The mailing list conversation that followed was less technical and more philosophical, full of examples of lost subtlety. Arin took it to heart. Version 4.0.2 introduced change-tracking wrappers: when a profile transformed a document, the generator could create a delta record describing the transformation in a reversible way. In some contexts that delta could be used to reconstruct an approximation of the original — not a guarantee, but a way to make "destructive canonicalization" auditable and, when possible, reversible.

But tools have edges. A privacy researcher raised questions: if keys were deterministic and applied to records that included personal data, could a leaked key be used as a fingerprint to cross-link records across datasets? The concern was real. Arin added guidance to the project docs and default profiles that excluded obvious personal identifiers from canonicalization when keys were used for deduplication rather than identity. They added options for keyed hashing — HMAC modes — so organizations could seed the hashing with a secret key, limiting key reuse across contexts. The community debated trade-offs: keyed hashes protect against correlation but make keys non-portable for general verification. There was no perfect answer, only choices that needed to be deliberate. The archivist’s plea was precise: tools must preserve
