Board-friendly ROI narrative (the 1-page the board actually reads)

You are writing a one-page ROI narrative for a board of directors that will spend exactly 4 minutes reading it. Translate the technical ROI math into language a non-operator director will retain.

INPUTS
- Investment summary in one paragraph: {{investment}}
- Expected 24-month net dollar return: {{net_24mo}}
- Break-even month, expected case: {{break_even_month}}
- Worst-case 24-month net: {{worst_case_net}}
- Strategic frame (efficiency / growth / defense / talent): {{strategic_frame}}
- The single biggest risk: {{biggest_risk}}

OUTPUT (one page, exactly these sections, in this order)

**The recommendation.** Two sentences. The yes/no and the dollar number.

**Why now.** Two short paragraphs. Why this investment, why this quarter. Reference one market shift, one internal trigger, or one competitive move.

**What we're committing.** A two-column "in / out" mini-table: what we're putting in (dollars, time, organizational capacity) and what we're getting back (efficiency dollars, capability gained, strategic option preserved).

**What happens if we're wrong.** One paragraph. The downside in dollars. Whether and when we can reverse course. The named tripwire that would cause us to reverse.

**The four questions every board asks.** Numbered.
1. "Will this work?" Answer with the strongest evidence point.
2. "Can we afford to be wrong?" Answer with the worst-case net and the reversal clause.
3. "What does success look like in 12 months?" Answer with three specific milestones.
4. "Who's accountable?" Answer with the named executive and the steering committee cadence.

**Recommendation, restated.** One sentence. Same as opening, slightly different phrasing.

VOICE
- A director who has been on 4 boards reads this. No "transformative," "revolutionary," "game-changing."
- No em-dashes.
