// Regression (2026-08-11): the vision model sometimes answered "Maaf, saya
|
||
|
|
// tidak melihat gambar apapun yang terlampir..." and that text was cached as
|
||
|
|
// a VALID vision_llm result. Every later analysis of the same image (same
|
||
|
|
// hash / phash) then hit the poisoned cache and the moderation LLM wrote
|
||
|
|
// "lampiran yang gagal terbaca" — image analysis seemed permanently broken
|
||
|
|
// even though 9router was responding fine.
