## Analysis

The core question is whether Japan Q2 2026 annualized GDP lands in a narrow 0.8pp band centered ~1.5pp above the fresh professional consensus (~0.5–0.8% per July JCER). Given Japan's documented >1pp preliminary-print forecast errors and the Q1 2026 upside surprise precedent, a ~10-15% probability for this band is well calibrated. The trimmed ensemble (12%) and the market (11%) agree almost exactly, and sibling bins price a coherent distribution around the same consensus center. With edge <5%, no factual disputes, and no mispricing signal, the protocol mandates SKIP. No tool calls were warranted — no load-bearing fact was in dispute.

## Key Evidence

July 15, 2026 JCER ESP survey (37 forecasters) puts Q2 annualized growth at ~0.3–0.8%; Dai-ichi Life at 0.3%. The 1.6–2.4% band requires a ~1–1.3pp upside surprise. Japan's preliminary GDP forecast errors exceed 1pp historically, giving the band a real but modest tail probability (~10–15%). Sibling market pricing (0.0–0.8% at 36%, 0.8–1.6% at 32%) is fully consistent with this distribution.

## Risks

It's resolution day and a trade would have lost because Japan's Q2 preliminary print surprised ~1pp above the JCER consensus (e.g., via inventory or net-export swings, as in Q1's 2.1% beat) and landed at 1.6–2.4% — but with only a ~1% edge, no trade was made, so the real risk avoided is paying spread/fees for no expected value.
