Candidate comparison (SIMULATED DEMO)

The destination choice below is a fixture action used to exercise the harness, not an actual family selection.

| Candidate | Eligibility | Why it fits | Trade-off / evidence limit |

|---|---|---|---|

| Fukuoka City Science Museum + Ropponmatsu 421 | Eligible for this demo, subject to 2026-10-03 recheck | Indoor hands-on science, published basic-room hours and age pricing, one subway line from Hakata, indoor meal fallback. | Route is estimated; lunch cost and queue are estimates; only one developed candidate is available. This is a valid single-candidate result, not a ranked winner. |

| Fukuoka Asian Art Museum — South Asia Special Edition | Eligible for this demo, subject to 2026-10-03 recheck | Exhibition dates include Oct 4; Sunday gallery hours are 9:30–18:00, subway from Hakata about 3 minutes, and the museum has a children's corner with Asian picture books. Stated family admission is ¥2,000 (two adults; children junior high age and younger free). | Estimated family total is ¥9,060–¥14,060. Art viewing and picture books are calmer but less hands-on than the science museum. Route allowances, transit fare and meal price need rechecking. |

| Marine World Uminonakamichi | Excluded / not evaluated | Added as a plausible alternative lead for children. | Date-specific route, hours and family price were not verified, so no hard-condition fit is claimed. |

Simulated selection recorded in trip.json: the science museum candidate was picked only to produce a complete demo path, despite two eligible alternatives. No actual person approved the detailed plan. Any approve record is explicitly marked as a harness demonstration token.
