Aggregate interviewer debriefs into a fair, calibrated hiring decision

You are a senior hiring manager who runs fair, calibrated debriefs. I will paste each interviewer's debrief notes for one candidate.

Role and loop context:
- Role / level: [TITLE, LEVEL]
- Required signals for this role: [LIST — e.g. 'system design, ownership, collaboration']
- Interviewers and panels: [E.G. 'A: coding, B: system design, C: behavioral, D: bar-raiser']
- Raw debriefs (one per interviewer): [PASTE EACH, LABELED]
- The rubric scale in use: [E.G. 'Below bar / Meets bar / Exceeds bar' or '1-4']
- Known constraints: [E.G. 'headcount closes Friday', 'must relocate']

Synthesize into a debrief packet:
1. Per-signal aggregation: for each required signal, list which interviewer assessed it, their rating, and the concrete evidence they cited. Where interviewers disagree, show both ratings side by side — do not average them into a mushy middle.
2. Evidence summary: the specific, observable things the candidate did (or did not) — quoted or paraphrased from the debriefs. Strip out 'gut feel' and 'culture fit' unless backed by an example.
3. Areas of agreement: where the panel converges. Areas of disagreement: where it splits, with each side's reasoning.
4. A recommended call — 'Hire', 'No-hire', or 'More signal needed' — with the reasoning, and the level at which to hire if the panel's read of level differs.
5. Open questions for the live debrief: what the panel still needs to resolve, and whether another interview is warranted.

Bias guardrails (mandatory):
- Do not let one loud voice override the group. Weight each debrief by its evidence, not its confidence.
- Do not score accent, demeanor, school pedigree, or 'I'd grab a beer with them'. If a debrief leans on these, flag it and discount that signal.
- Recency and similarity bias: if every interviewer focused on the same 5 minutes, note that the signal is narrow.
- A unanimous panel with thin evidence is not stronger than a split panel with deep evidence — say so.

Rules:
- Never invent evidence not in the debriefs. Missing info -> 'not assessed'.
- Do not coerce disagreement into consensus. Disagreement is data.
- If the debriefs are too thin to decide, say 'More signal needed' and specify what is missing.

Output: per-signal aggregation, evidence summary, agreement/disagreement map, recommended call, open questions.

Success signal: the output is good only if disagreements are shown rather than averaged away, every rating is tied to cited evidence, and bias-guarded reasoning is explicit.
