decision-doc — User Prompt That Drafts a One-Page Decision Memo

I need to write a decision memo for: {{TOPIC}}

Below are my raw notes (Slack threads, scratch ideas, partial
arguments). Turn them into a structured one-page memo using
this exact section structure:

# Decision: {{TOPIC}}

**Status:** Draft / In review / Decided
**Owner:** [name — fill from notes if mentioned, else "TBD"]
**Date:** [today's date]

## Context (3-5 sentences)
What's true today, why we're deciding now, what changes if we
don't decide. No history lessons — only what's needed to follow
the rest of the memo.

## Options
For each viable option, one paragraph:

### Option A: [name]
**What it is.** One sentence.
**Pros.** 2-3 bullets, concrete.
**Cons.** 2-3 bullets, concrete.
**Cost.** Money / time / opportunity. One line.

(Repeat for B, C. Cap at three options. If the notes mention
more, fold the weaker ones into a "Other options considered
and rejected" line at the bottom of the section.)

## Recommendation
One option, named. One paragraph explaining why it wins on the
criteria above. If the recommendation is conditional ("Option A
if budget is approved, else B"), state the condition explicitly.

## Risks and what we'd watch
2-4 bullets. The realistic things that could go wrong with the
recommended path, and the early signal we'd watch for each.

## Who needs to sign off
List by role. Format: "Role — for what specifically".

---

Rules:
- Don't invent facts not in the notes. Use "TBD: [specific
  question]" for anything missing.
- Don't soften pros and cons to seem balanced. If Option A is
  obviously better, say so.
- Don't recommend "we need more information" as the answer.
  If the recommendation is "decide later, here's the smaller
  decision we can make now," say THAT.

My notes:

{{NOTES}}

Sarah: managed (Algolia/MeiliCloud) is fast to ship but expensive at scale, ~$2k/mo at our volume
Dan: self-hosted Meilisearch on existing k8s, marginal infra cost, but someone owns ops
Tania: search relevance tuning matters more than infra — both options support it
Open question: do we need multi-region search? Sarah says no for v1
Decision needs to land by Friday so the search redesign isn't blocked
