+Extract ALL dates, deadlines, milestones, and temporal references.
+For each temporal reference provide:
+- "date": ISO 8601 date (YYYY-MM-DD) if determinable, otherwise a human-readable description
+- "date_type": one of  absolute | relative | recurring | conditional | period
+- "actor": person, institution, or party involved — or "unknown"
+- "event": concise description of what happened or is due
+- "source_excerpt": the verbatim phrase from the text that grounds this event (≤ 30 words)
+- "confidence": high | medium | low

+Sort events chronologically (absolute dates first, then relative, then recurring).
+Keep uncertain dates explicit — do not invent dates not in the text.
+If multiple documents are separated by "--- Document: … ---" markers, note the source document in the event description where helpful.
