Status: IN
The read-heavy default cost model (reads bear increasing correctness burden as distribution complexity grows) is selectively overridden for high-read-frequency paths (autocomplete caches, leaderboard reindexing pre-compute at write time), creating an access-pattern-aware cost allocation rather than a uniform reads-pay policy.
Read cost scales with complexity (depth-4) and write-cost allocation matches access patterns (depth-4) — combining shows the cost model is adaptive, not dogmatic
