What is skill curation and why can't we just write the rules once?

Rules written months apart give conflicting guidance on overlapping cases. A reference points at something since renamed and resolves to nothing. A rule for a replaced system keeps firing. None of it errors; the system keeps answering, slightly worse, and the degradation gets attributed to the model.

Oxcyon curates the corpus continuously: when a skill changes, its dependents are identified and reconciled, contradictions resolve to a single authority, and references that no longer resolve are repaired before they fail quietly. Each rule keeps its named owner and its review interval on the record, so the policy remains the client's even where the maintenance is not.
