// Characterization of toPositiveNumber / buildCacheUsageLogMeta / attachLogMeta — cache-usage log
|

// meta helpers extracted from handleChatCore (chatCore god-file decomposition, #3501). Locks: the
|
|
// positive-number coercion, the cache-token derivation across top-level and prompt_tokens_details
|
|
// shapes (null when no cache fields), and the _omniroute meta attachment/merge.
