Strategy convergence strength in an uncoordinated repo appears predictable from abstraction overhead: streaming (zero abstractions) converges strongest, hash-then-stream (one preprocessing step with Counter/set) converges next, sort-then-scan (ordering prerequisite plus pointer management) converges weakest — the adoption barrier gradient closely tracks the abstraction cost gradient.
both describe the same hierarchy from different causal angles (adoption vs. infrastructure); combining reveals abstraction cost is the measurable predictor of convergence
