Status: Multi-paradigm. Per Non-clustered HAA cluster pilot Source 4 (closed 2026-05-07): [CONCEPT-BLENDING-PARTIAL-IMPLEMENTATION]. Information-theoretic + GA/CMA-ES + category-theoretic colimit/pushout + PeTTa-port branches are [IMPLEMENTATION-BACKED-CORE] in iCog-Labs-Dev/conceptBlending at HEAD 9675e5e. Quantale weakness, paraconsistent interference, and HoTT-adjacent material are [PAPER-ONLY-FORMAL-EXTENSION] at this snapshot. The TransWeave / MORK-native / WILLIAM / Symbolic-Heads downstream paths described below are whitepaper / roadmap claims, not currently-wired implementation.
Concept blending is a primary heuristic for creativity — creating novel ideas by merging properties from two or more source concepts so that the result shows useful emergent structure. In Hyperon, blends are not bag-of-words tricks but metagraph constructs that can be tested by the same evaluators that rate patterns, proofs, or programs, making blending a first-class, auditable operation.
Blending takes two or more source concepts (represented as subgraphs in AtomSpace), identifies structural alignments between them, and constructs a merged graph that preserves key constraints from each source while introducing novel combinations. The whitepaper gives the intuitive example of "sky-garden" = aerial platform + botanical garden — a blend that inherits structural properties from both sources.

Author attribution note: Ben Goertzel sole-author on all four 2025-2026 Hyperon-era papers in the local archive; targeted searches for "Eskridge" / "eskridge" returned zero hits. Older OpenCog-era Goertzel/Eskridge concept-blending work may exist outside the local Mattermost archive (per V4-1 cluster-pilot finding); flagged for future retrieval.
The iCog-Labs-Dev/conceptBlending repo at committed HEAD 9675e5e contains four implementation branches. Per V4-2 methodology guard: extract against committed HEAD only; the local working tree had hundreds of staged file deletions (likely a reorganization in flight) that are NOT a valid filesystem source surface.

[PAPER-ONLY-FORMAL-EXTENSION] applies to: quantale-weakness-class structures (no quantale or weakness implementation in conceptBlending HEAD); paraconsistent interference (zero paraconsistent / interference hits at git grep -i); and HoTT-adjacent identity-aware semantics (zero HoTT / homotopy hits). These formalisms are paper-rigorous but not exercised by code in this repo at the audited snapshot.
