/**
|
|
* Tests for #3890: the cache-aware `skipSystemPrompt` flag was computed by
|
|
* getCacheAwareStrategy() but dropped by selectCompressionStrategy() (which can only
|
|
* return a mode string). resolveCacheAwareConfig() applies it: in a caching context the
|
|
* system prompt must stay uncompressed (it is part of the cacheable prefix) even when the
|
|
* operator disabled preserveSystemPrompt.
