Current-source profiling shows repeated alias derivation reserving maps for blank and duplicate optional inputs. Scan at most eight normalized keys on the stack, then fall back to a map for larger vocabularies. Preserve exact lowercasing, first spelling, order and detached allocated-empty output with the independent original map oracle, including Unicode and large identities.
Contract-Neutral: Allocation strategy only; canonical aliases, superseded IDs, identity matching, tenant/source ownership, registry invalidation, History and broadcast wire contracts are unchanged.
