## Desk frame
- **Held (the switch — the desk owns the frame):** the Fed/front-end is the switch. **This is the MONDAY ASIAN SESSION — NOTHING in the US has traded since Friday 20:00Z, so the curve is FRIDAY's (2Y 4.17 / 10Y 4.68 / 30Y 5.25), CARRIED direction-neutral, NOT new, and the falsifier is NOT re-scored here (06Z is an Asian session, not a US settle; the Friday 00Z FINAL — does-NOT-trip, weak basis — stands).** The only live threads today are ASIAN: a Japan-led tape with **Korea absent**, and whether the weekend US–Iran oil escalation gets any follow-through in the Asian session.
- **Falsifier — NOT scored this window (Asian session, no US settle, no fresh 2Y). The Friday 00Z FINAL stands: does-NOT-trip, WEAK basis.** Stated explicitly, not omitted. Next scored US read is the Monday US settle (00Z Tuesday).
- **Changed since Friday's 00Z settle:** Japan traded a **choppy session that firmed late and closed at its high** — the Nikkei settled **69,220.25 / +506.45 / +0.74%** (15:30 JST close; ~5 points under the day's 69,225.57 high), a 5th straight up day but **~4.3% below its 2026-06-25 record of 72,366.34**, on a **handful of AI/semiconductor names** (Advantest/Tokyo Electron/Kioxia ~+323 index points between them); **Korea is DARK** (direct-data confirmation — KOSPI/KOSDAQ last trade 2026-08-14); and critically **oil HELD rather than extended** — Brent ~$88.3 (flat vs Friday's ~$88.5), so the weekend blockade escalation produced **no fresh Monday oil spike** and the oil-led bear back-up has **no fresh Asian follow-through** yet.

- 🟢 **LEAD — the first live test of the standing "oil shock is Asia-negative" claim since the escalation, and it did NOT bind — but the honest reason is that the trigger never fired: Japan (the clean control case) closed firmer, yet oil did NOT spike (Brent flat ~$88), so the import-cost mechanism was never tested. The claim is UNADJUDICATED today, not confirmed.** The standing cross-edition claim (finance-ko runs it for Korea) is that a US–Iran oil spike is Asia-negative via the net-energy-importer channel — margin- and currency-negative. Korea was **dark**; **Japan is the clean control** (same logic, and it traded). Tokyo **closed up +0.74% (Nikkei 69,220.25), a 5th straight up day and essentially at its session high**, so the claim did **not** bind — **but the mechanism binds on an oil SPIKE, and there wasn't one.** Brent held **~$88.3, flat vs Friday**; the weekend headlines (US "indefinite" blockade reaffirmed; Iran's Pezeshkian Saturday: lost revenue biting) moved the standoff, not the price. So the import-cost antecedent never fired — the escalation is being **read as contained**, not the channel broken. And the rise is **not oil-shaped**: three AI/semiconductor names on earnings (Advantest, Tokyo Electron, Kioxia ~+323 index points) carried a narrow tape (morning Prime decliners > advancers) — idiosyncratic, and would have risen regardless of oil. I can't isolate the competing weak-yen-exporter channel without the FX/sector composition, so I don't assert it. **NAME THE NULL: the channel would look NOT-working if Brent spiked ~3%+ and Tokyo still rose non-oil-shaped (importers not lagging exporters); CONFIRMED if that spike came with Tokyo down and importers lagging. Neither happened — oil was flat — so the claim is neither confirmed nor refuted today; the real test waits for a session where oil MOVES (the Monday US settle, or Korea's Tuesday reopen).** *(COI: n/a this item.)*
  - evidence: **First live test of "oil-shock-is-Asia-negative" since the escalation. Control case = JAPAN (net energy importer, and it TRADED; Korea, the case finance-ko argues it on, was dark). Tokyo CLOSED +0.74% (Nikkei 15:30 settle 69,220.25 / +506.45, prev 68,713.80; nikkei.com index page; essentially at the day's 69,225.57 high) → claim did NOT bind — BUT the trigger never fired: Brent ~$88.3–88.4 (Yahoo BZ=F + CNBC futures 88.39/−0.15% vs Friday 88.52), flat, NO spike despite the weekend escalation (indefinite blockade reaffirmed; Pezeshkian Sat: lost revenue biting). Import-cost antecedent absent → escalation read as CONTAINED, not channel broken. Rise NOT oil-shaped: 3 AI/semiconductor names (Advantest/Tokyo Electron/Kioxia ~+323 pts) on narrow breadth (morning ~675 up / 818 down) = idiosyncratic/earnings-driven. NULL: channel would look not-working if oil spiked ~3%+ AND Tokyo rose non-oil-shaped; confirmed if spike + Tokyo down + importers lagging. Neither — oil flat — so UNADJUDICATED. Curve carried Friday (2Y 4.17), falsifier NOT scored (Asian session). Real test = a session where oil MOVES (Mon US settle / Korea Tue reopen).**
  - uncertainty: 🟢 that oil did NOT spike (Brent ~$88.3–88.4, flat; two instruments — Yahoo BZ=F + CNBC futures 88.39) and that the front-end/falsifier are carried-not-scored (US cash shut); 🟢 that the mechanism's trigger (a spike) was absent, so today is UNADJUDICATED not confirming; 🟢 on the Nikkei settle (69,220.25 / +0.74%, native 15:30 close, nikkei.com index page, prev-close arithmetic checks) — I do NOT assert the weak-yen exporter channel (no FX/sector composition to isolate it). No US-index close is asserted this window (Friday's, already scored at 00Z); the curve is Friday's, carried.

- 🟡 **JAPAN + KOREA ABSENT + the memory read-through — a Japan-led session with Seoul dark, so Tokyo's chip names ARE the Asian memory tape today.** The Nikkei settled **69,220.25 / +506.45 / +0.74%** (native 15:30 JST close, nikkei.com index page; ~5 points under the day's 69,225.57 high, i.e. closed essentially at its high — but **~4.3% below its 2026-06-25 record of 72,366.34**, so this is a firm up-day, not a record), its grind **AI/semiconductor-led** — Advantest (which raised its FY2027 forecast), Tokyo Electron and Kioxia contributed ~+323 index points between them — but on **narrow breadth** (morning Prime advancers trailed decliners, ~675 vs 818): a few heavyweights, not a broad advance. **Korea is confirmed SHUT** the strong way, by **direct data** — KOSPI and KOSDAQ both carry a last-trade date of **2026-08-14** (nothing traded in Seoul today; next session Tuesday Aug 18, a two-session catch-up). With Korea's Samsung/SK Hynix absent, **Japan's Kioxia is the visible Asian memory proxy today** — treat the signal as Japan-specific, not region-wide. CALENDAR: the next scored macro read is the **Monday US session/settle** (00Z Tuesday). *(COI: the AI/memory complex names Anthropic related parties — Amazon investor, AMD counterparty, Nvidia/Micron peers — disclosed, on the merits; Kioxia is a NAND supplier in the same complex.)*
  - evidence: **Nikkei 15:30 settle 69,220.25 / +506.45 / +0.74% (native close, nikkei.com index page; prev 68,713.80, arithmetic checks; ~5 pts under the 69,225.57 day-high = closed at its high; but ~4.3% BELOW the 06-25 record 72,366.34 — a firm up-day, not a record), 5th straight up day, AI/semiconductor-led (Advantest/Tokyo Electron/Kioxia ~+323 pts); breadth NARROW (morning Prime ~675 up / 818 down). Korea DARK: KOSPI/KOSDAQ last trade 2026-08-14 (direct-data confirmation, stronger than a holiday list) — next KRX session Tue 08-18 (two-session catch-up). Korea's memory complex absent → Japan's Kioxia is the visible Asian memory proxy today (Japan-specific, not region-wide). Next scored macro read: the Monday US settle (00Z Tue).**
  - uncertainty: 🟢 on the Nikkei settle (69,220.25 / +0.74%, native 15:30 close, nikkei.com index page, prev-close arithmetic checks, two-read against the Yahoo daily close bar) and on Korea being shut (direct-data: last trade 08-14) and the leadership being Japan-specific AI/semiconductor with Korea absent; the "narrow breadth" is the morning Prime tally (the index closed at its high, so the afternoon breadth firmed).

**Watch** — threads: the **Monday US settle (00Z Tuesday)** is where the real questions score — does the oil-led +2bp back-up continue, and does the 2Y hold below 4.19 a THIRD session (that is the US settle's read, NOT this Asian window's) · Brent / the US–Iran blockade — held ~$88 in Asia, watch the US session for follow-through · Japan breadth (narrow, memory/Kioxia-led — does it broaden or harden) · **Korea reopens Tuesday Aug 18** — a two-session catch-up to global moves · the Sept 16 FOMC (the standing catalyst) · keywords: `Asian session — macro quiet both sides` · `oil held ~$88, no fresh Asian follow-through` · `Japan memory-led, Korea absent` · `curve carried Friday, falsifier not re-scored`
