 * column is enough to discriminate which kind of error fired
 * (`budget_yield_unrecovered`, future out-of-funds, etc.).
 *
 * Intentionally *not* a member of the backend's `LLMCallSite` enum:
 * that enum binds config lookup, not the shape of the `call_site`
 * column. Compaction-route filters that match
 * `call_site = 'compactionAgent'` already treat this value as a
