+    "=== THE CROSS-FAMILY MERGE PROBLEM ===\n"
+    "Standard weight merging (averaging, SLERP, TIES, DARE, etc.) requires "
+    "identical architectures. These 9 models have different parameter naming "
+    "schemes (e.g., 'q_proj' vs 'Wqkv'), different attention head dimensions, "
+    "different FFN layouts, and different hidden sizes. Naive merging is "
+    "impossible across these boundaries.\n\n"
+    "=== HOW crdt-merge SOLVES IT ===\n"
+    "crdt-merge uses a two-layer CRDT (Conflict-Free Replicated Data Type) "
+    "architecture called CRDTMergeState:\n\n"
+    "Layer 1 -- Canonical Key Namespace and CRDT State Management:\n"
+    "Maps each architecture's parameter names to shared functional roles "
+    "(10 architecture families covered). For example, Phi's 'Wqkv' and "
+    "Llama's 'q_proj/k_proj/v_proj' both map to the same canonical "
+    "attention-query/key/value roles. Uses OR-Set CRDT semantics where "
+    "merge = set union (trivially commutative, associative, idempotent). "
+    "Version vectors provide causal ordering. Merkle hash trees provide "
+    "integrity verification and deterministic seeding for Layer 2.\n\n"
+    "Layer 2 -- Deterministic Strategy Execution with Alignment:\n"
+    "Given the converged contribution set from Layer 1, applies the merge "
+    "strategy as a deterministic pure function. Three mechanisms ensure "
+    "determinism: (1) canonical ordering via SHA-256 content hashes, "
+    "(2) seeded randomness derived from the Merkle root, (3) pure function "
+    "guarantee. For cross-architecture merging specifically, Layer 2 applies "
+    "per-tensor Procrustes alignment (finding optimal orthogonal rotation "
+    "between weight spaces) and SVD-filtered delta absorption (decomposing "
+    "donor contributions via singular value decomposition and filtering noise "
+    "before absorbing into the anchor's weight space).\n\n"
+    "=== THE FOUNDATIONAL RESEARCH PAPER ===\n"
+    "Title: 'Conflict-Free Replicated Data Types for Neural Network Model "
+    "Merging: A Two-Layer Architecture Enabling CRDT-Compliant Model Merging "
+    "Across 26 Strategies'\n"
+    "Author: Ryan Gillespie\n"
+    "Available at: https://ssrn.com/abstract=6545518\n\n"
+    "Core finding: ALL 26 neural network merge strategies tested fail the "
+    "algebraic properties required for conflict-free distributed operation. "
+    "Associativity is the universal failure point (25/26 strategies fail it). "
+    "This is structural, not an implementation bug: normalisation-based merges "
+    "CANNOT simultaneously satisfy commutativity, associativity, and "
+    "idempotency (proven as Proposition 1 in the paper).\n\n"
+    "The 26 strategies tested include: weight averaging, SLERP, TIES, DARE, "
+    "DARE-TIES, DELLA, Fisher merging, Task Arithmetic, AdaMerging, ADArank, "
+    "DAM, dual projection, EMR-Merging, evolutionary merge, genetic merge, "
+    "LED merge, linear interpolation, Model Breadcrumbs, negative merge, "
+    "RegMean, Representation Surgery, safe merge, split-unlearn merge, STAR, "
+    "SVD knot tying, and weight scope alignment. Of these, 15 have peer-"
+    "reviewed publications; 11 are derived/community strategies from MergeKit.\n\n"
+    "Key strategy equations:\n"
+    "- Weight Averaging: theta_merged = (1/n) * sum(theta_i). Commutative "
+    "and idempotent, but NOT associative: f(f(a,b),c) = (a+b+2c)/4 while "
+    "f(a,f(b,c)) = (2a+b+c)/4.\n"
+    "- SLERP: Spherical linear interpolation along great circles. Commutativity "
+    "holds only at t=0.5. Associativity fails because composing geodesic "
+    "interpolations changes the reference great circle.\n"
+    "- TIES: Three-step pipeline (trim, sign-elect, merge). Trimming thresholds "
+    "depend on input set, breaking associativity.\n"
+    "- DARE: Stochastic Bernoulli mask + rescaling. All three properties fail.\n"
+    "- Fisher: Commutative (summation), but intermediate Fisher information is "
+    "lost during pairwise merging, breaking associativity.\n"
+    "- Task Arithmetic: theta_base + lambda * sum(tau_i). The only strategy "
+    "that is associative, but it fails idempotency.\n\n"
+    "=== KEY THEOREMS ===\n"
+    "Theorem 1 (CRDT Compliance): The CRDTMergeState merge operation satisfies "
+    "commutativity, associativity, and idempotency. The state space forms a "
+    "join-semilattice (CvRDT).\n"
+    "Theorem 2 (Convergence): If two replicas have the same visible contribution "
+    "set, they compute identical merged models, regardless of message ordering.\n"
+    "Corollary 1 (Universal): ANY merge strategy satisfying the purity and "
+    "determinism assumptions can be made CRDT-compliant through the wrapper.\n"
+    "Theorem 3 (Complexity): CRDT overhead is O(k log k) time and O(k) space, "
+    "independent of model size p. merge() is O(|A1|+|A2|), add() is O(p) for "
+    "SHA-256 hashing, resolve() is O(k log k + T_sigma(k,p)).\n\n"
+    "Three assumptions required: (1) Strategy Purity -- the merge strategy must "
+    "be a pure function with no external state, (2) Computational Determinism -- "
+    "all replicas use identical ISA, libraries, IEEE 754 rounding, "
+    "(3) Collision Resistance -- SHA-256 collision probability < 2^-128.\n\n"
+    "=== EMPIRICAL VALIDATION ===\n"
+    "Tier 1 (Controlled): 4x4 float64 tensors. 0/26 strategies pass all 3 CRDT "
+    "properties raw. With CRDTMergeState wrapper: 26/26 pass (104/104 tests).\n"
+    "Tier 2 (Production Scale): GPT-2-XL (1.5B params, 193 layers) and "
+    "Mistral-7B (7.24B params, 224 layers). 208 strategy-level tests, "
+    "43,368 layer-level property checks. 100% compliance through the wrapper.\n"
+    "Tier 3 (Multi-Node): 100 nodes, 20 random gossip orderings, all converge "
+    "to bitwise-identical results (max element-wise difference = 0). "
+    "Network partition test: 100 nodes split into 10 partitions, healed, "
+    "all converge. Cross-strategy sweep: all 26 strategies converge on 10 nodes. "
+    "CRDT overhead consistently below 0.5 ms.\n\n"
+    "=== IMPLICATIONS ===\n"
+    "This enables fully decentralised, coordinator-free model merging with "
+    "formal convergence guarantees. Unlike Federated Learning (which requires "
+    "a central coordinator), crdt-merge allows peer-to-peer model combination "
+    "where participants merge independently in any order and provably converge "
+    "to identical states.\n\n"
+    "Future directions include: Byzantine fault tolerance via trust-as-CRDT "
+    "(trust evidence as a monotonically-growing CRDT within Layer 1, enabling "
+    "consensus-free Byzantine exclusion), delta-state optimisation for "
+    "bandwidth efficiency, cross-hardware determinism validation, and "
+    "integration with federated learning pipelines.\n\n"
