Graph Traversal on Change

Rule libraries have no declared foreign keys. The dependencies are semantic — one rule assumes a definition another supplies, a prompt relies on a pattern a third establishes — so a change made in isolation leaves the library partly following the new rule and partly the old. The symptom is intermittent behaviour that resists diagnosis, because nothing errors and the divergence only appears on the paths that happened to load the stale dependency. Traversal replaces that with a deterministic sweep: before a rule is modified, what depends on it is enumerated; after modification, those dependents are reconciled.

Inbound reference discovery is part of Oxcyon's curation routine rather than an occasional audit. That is what makes is this safe to delete and what breaks if this changes answerable questions — and it is the reason a Centralpoint corpus can be maintained at scale rather than frozen once it exceeds the size any one person can hold in their head.
