ISS_DEDUP_FAIL
Inbound e-mail dedup lookup failed
The dedup matcher (SQL candidate load or LLM ranker) raised an error while trying to decide whether an inbound e-mail continues an existing issue. The mail falls through to the fresh-ticket branch as a safe default; a persistent failure risks reintroducing duplicates and should be investigated.
