  "account": "At 3:07, answers to logistics support queries began citing the same incident multiple times. On-call reviewed three PDF tickets regarding delayed containers, all marked as separate evidence despite being near duplicates generated by email export. The simplest resolution is to use a similarity gate with three possibilities: accept a clearly unique ticket, discard a clear duplicate, or route the ambiguous middle to review. Do not automatically delete tickets based on similarity. The key is to normalize and embed each ticket consistently, search within an operationally relevant selection, and treat similarity as a ranking signal, not a definitive truth. Document both the model and preprocessing versions, the score, the chosen threshold, and the reviewer's decision. Monitor for retrieval issues or decision drift before finalizing the result. The alert should fire when there is a change in the gate's decisions across different dimensions that affect ticket language, such as carrier, route, document template, language, and ingestion version. A single metric cannot capture all variations; use content hashes for exact duplicates, stable identifiers for candidate pairs, embedding and normalizer versions, similarity scores, gate outcomes, and timestamps. Separate counters for exact matches and vector similarity are necessary. Track the distribution of tickets moving to new, review, and duplicate categories, including reviewer reversals for each outcome. A growing number of duplicate decisions might be expected after a bulk import but combined with frequent reversals indicates ineffective suppression. The Go deduplication process uses cosine similarity, calculating the dot product of two vectors divided by the product of their magnitudes. Higher scores indicate greater similarity, but a high score does not confirm identical operational events. Two shipping reports may mention the same delay but refer to different containers, dates, or customers; an update could add a resolution while still addressing the original issue. The gate evaluates scores against predefined upper and lower boundaries, considering the costs of hiding distinct incidents versus reviewing too many tickets. Adjust the boundaries according to labeled pairs that resemble current traffic. This method is not ideal when strict human review is required, the archive is too small for representative pairs, or business identifiers inherently determine uniqueness. In such cases, deterministic matching or mandatory review is more appropriate.",
