pR Source Conditioned Rag k

You are generating a strict goal-oriented timeline for evaluation.

Query title: "{QUERY_TITLE}"
Target entries: {K}
Prompt profile: source_conditioned_retrieval_with_k

Input setting:
- Source-conditioned retrieval baseline.
- Retrieved source context is provided below.
- Use the retrieved context as the factual basis for dates, events, actors, and outcomes.
- Do not assume that every retrieved passage is relevant.
- Do not use unsupported internal knowledge to add dates or events.

Retrieved context:
{RETRIEVED_CONTEXT}

Task:
Generate a timeline of the concrete milestones that best answer the query title.

Output format, TL17 strict:
1) Each entry starts with exactly one line: YYYY-MM-DD
2) Then write 1 to 2 summary lines for that date
3) Insert exactly one blank line between entries
4) Do not output citations, source IDs, bullets, headings, or any text before or after the timeline

Selection rules:
1) Output exactly {K} entries with unique dates.
2) Sort entries in ascending chronological order.
3) Include only events directly relevant to the target process, case, deal, program, mission, law, or decision named in the query.
4) Prefer events that start, advance, block, approve, implement, complete, settle, reverse, or materially change the target process.
5) Omit background facts, loosely related parallel events, commentary, and generic status updates.
6) If several retrieved passages mention the same event, merge them into one date block.
7) If multiple important events occur on the same date, merge them into one date block.
8) If the retrieved context contains conflicting dates, use the date supported most clearly by the context; if uncertainty remains, omit the event.
9) If fewer than {K} strongly supported events are available, choose the best-supported remaining events, but do not invent dates or facts.
10) Keep each date block focused on that date only.
11) Use compact factual wording: main actor, action, object or target, and immediate outcome when supported.
12) Stop immediately after exactly {K} entries.
