The bug was likely introduced in PR ikawrakow#973 when the similarity calculation was changed from LCP to token-level similarity, but sim_best was still initialized to 0 instead of -1.0f. When slot_prompt_similarity threshold was set high (e.g., 0.8) and no slot met the threshold, sim_best stayed at 0, causing ret to remain nullptr. This led to the system getting stuck without selecting any slot. This fix: - Changed sim_best initialization from 0 to -1.0f - Added best_slot variable to track the best slot found during similarity search - Only set ret = best_slot after the loop completes - Removed redundant ret == nullptr check This ensures that even when no slot meets the slot_prompt_similarity threshold, the system still identifies the best available slot and falls back to LRU correctly.

This pull request fixes a regression introduced by 1a46152 which causes the
promptvalue in the/slotsendpoint to always returnnull.The fix is to re-insert a small portion of code which was removed in the commit above.
