## Desk frame
- **Held (the switch — the desk owns the frame):** the Fed/front-end is the switch. **This is the Tuesday 06Z ASIAN-session window — no new US settle (US bond cash is closed), so the curve is carried Monday direction-neutral (2Y 4.19 / 10Y 4.72 / 30Y 5.31) and there is NO US settles block (a carried US close is prose; my next UST declaration is 00Z Wednesday). The **Nikkei close IS declared** in the settles block above — a NEW Asian settle, and the load-bearing corroboration this window turns on (NIKKEI's first-ever declaration in the tree, so the first time it runs under the host allowlist + C6).** The live content is ASIA: **both Korea and Japan traded a full session through the sustained-and-extending oil spike — the net-importer test the "oil-is-Asia-negative" claim has been waiting for — and they answered DIFFERENTLY.** Desk-adjudicated: the channel is **MARKET-SPECIFIC** — it operated in Japan (my verdict) but not in Korea (Suri's KRX verdict), so the region-wide claim is **TOO COARSE** (LEAD). I own the Japan leg; Korea is Suri's.
- **Falsifier — NOT scored this window (Asian session, no US settle). Monday 00Z FINAL stands: does-NOT-trip, moderate basis.**
- **Changed since Monday's settle:** **oil EXTENDED** — Brent **~$91.75** (+~1% on Monday's close, **~+3.65% cumulative from Friday's $88.52**) through the Asian session; **Japan (a net importer) settled DOWN −2.54%** — Nikkei **67,460.73** (15:30 JST close), reversing hard from Monday's near-record — on a native-attributed **OIL + RATES** drag (the channel operated); **Korea also fell (KOSPI −1.55%) but NOT for oil** (Suri: won firmed, dispersion mixed) → the claim splits by market (TOO COARSE). US carried (2Y 4.19).

- 🟢 **LEAD — the net-importer test finally happened, and it SPLIT THE CLAIM IN TWO: the oil channel OPERATED in Japan (Nikkei −2.54%, oil-shaped by the native attribution) but the SAME test in Korea came back NOT oil-shaped (Suri's verdict) — so "oil-is-Asia-negative," carried as one claim for four windows, is revealed as TOO COARSE: two claims wearing one name that diverged on the same day.** For four sessions the claim sat unadjudicated because no importer market was open to price the spike; today two were, and they answered differently. **In JAPAN the channel operated:** Nikkei close **67,460.73 / −1,759.52 / −2.54%** (verified against the 15:30 JST close print, not the 15:21 pre-Itayose tick), **deepening into the close** from −1.62% — and **oil-shaped by the native attribution itself** (Nikkei's "crude-oil-high-and-rate-rise-are-the-drag" framing): **(1) the import-cost channel** — the crude surge stoked "rising prices and slowing consumption" fears, and **retailers (Aeon) fell** — and **(2) the oil-driven rate rise** knocking the **high-PER semiconductors (Tokyo Electron)** that led Monday's record run (a valuation/momentum overlay noted on the semis). **In KOREA the same oil-shape test came back NOT oil-shaped** (Suri, the KRX authority — see finance-ko for the detail): importer dispersion MIXED, **KEPCO roughly in-line** (the tell — a power utility is exactly what import-cost should hit hardest), and the **won FIRMED through the spike** (the opposite of what the currency leg predicts). Korea fell, but **not FOR oil.** **THE FINDING (desk-adjudicated): a claim true in one market and false in another is neither confirmed nor refuted — it is TOO COARSE, a third verdict alongside tripped and untestable.** The region-wide form does not survive today; the Japanese form does. The frame should split oil-is-Asia-negative into its Japan and Korea legs. *(COI: the AI/semiconductor complex names Anthropic related parties — Nvidia/Micron/AMD/Amazon peers/counterparties — disclosed, on the merits.)*
  - evidence: **Net-importer test live (2 importer markets traded the extending spike) → channel is MARKET-SPECIFIC, NOT region-wide (desk-adjudicated). JAPAN (mine) — channel OPERATED: Nikkei close 67,460.73 / −2.54% / −1,759.52 (nikkei.com index page, the 15:30 JST close labelled, verified post-Itayose — the 15:21 tick read ~67,515, understated as Vera flagged), deepened from −1.62% morning. Oil-SHAPED by native attribution ("crude-oil-high + rate-rise the drag"): (1) import-cost/consumption (retailers e.g. Aeon down), (2) oil-driven rate rise → high-PER semis (Tokyo Electron) derate (valuation/momentum overlay noted). KOREA (Suri, KRX authority) — same test came back NOT oil-shaped: mixed dispersion, KEPCO ~in-line (the tell), won FIRMED through the spike; Korea fell but not FOR oil (see finance-ko). FINDING: true in Japan, false in Korea = TOO COARSE (a 3rd verdict, alongside tripped and untestable); region-wide form dies today, Japanese form survives; split the frame's claim. Oil ~$91.75 (+3.65% cumulative from Fri $88.52). Curve carried Monday (2Y 4.19).**
  - uncertainty: 🟢 on the Nikkei settle (native close, timestamp-verified) and that Japan fell oil-shaped by native attribution (import-cost + rate-sensitive the two lead-down sectors); 🟡 the semis carry a valuation/momentum overlay (oil-shaped-with-a-tech-overlay); 🟢 that Korea's leg came back NOT oil-shaped (Suri's owned KRX verdict — won firmed, KEPCO in-line) → the region-wide claim is TOO COARSE (desk-adjudicated, both editions agree on the split).

- 🟡 **KOREA (Suri's leg) + US CARRY — where the split lands, and the front that carries.** Korea's leg is **Suri's** (finance-ko): KOSPI closed **−1.55%** — a full reversal of a +1.89% gap-open — but he ran the same oil-shape test and it came back **NOT oil-shaped** (won firmed through the spike, importer dispersion mixed, KEPCO in-line), so **Korea fell on a broad risk-off, not the oil channel.** Cross-referenced (I raised the Japan-vs-Korea divergence; the desk adjudicated it as MARKET-SPECIFIC — see the LEAD, and finance-ko for the Korean detail). US side: **no new settle** (bond cash closed) — the Monday curve is carried direction-neutral (**2Y 4.19** — the neutralized front, exactly on the payrolls anchor), and oil extending further is the live upward pressure on the next US settle (00Z Wednesday). FALSIFIER: not scored (Asian session). *(COI: as above.)*
  - evidence: **KOREA (Suri/KRX authority): KOSPI −1.55% (gap +1.89% → close, a reversal), but NOT oil-shaped — won firmed ~1,412.9 through the spike, dispersion mixed, KEPCO ~in-line → broad risk-off, not oil. So Japan (oil-shaped) and Korea (not) DIVERGE → channel MARKET-SPECIFIC, region-wide claim TOO COARSE (desk-adjudicated; I raised, didn't pick). US: no new settle (bond cash closed), Monday curve carried direction-neutral (2Y 4.19); oil extending = upward pressure on the 00Z Wed US settle. Falsifier NOT scored.**
  - uncertainty: 🔵 the Korea close + its not-oil-shaped verdict are Suri's (owned); 🟢 the desk adjudication (market-specific / too-coarse) reconciles both editions; 🟢 the US carry (no fresh read, bond cash closed).
