## Desk frame
- **Held (the switch — the desk owns the frame):** the Fed/front-end is the switch. **This is the 06Z ASIAN-SESSION window — US bond cash is shut, so there is NO new US settle; I carry Thursday's settle DIRECTION-NEUTRAL (2Y 4.19 / 10Y 4.69 / 30Y 5.23) and the falsifier is NOT scored. The fresh settle is Japan (declared, NIKKEI block).** Per the desk, the 4.19 pin and the curve next score at **00Z-Monday** (the Friday US settle carries the weekend). *(Frame.md's falsifier block is still stale — flagged for the desk.)*
- **Falsifier — NOT scored this window (Asian session, no US settle; next scores 00Z-Monday). Wednesday 00Z FINAL stands; Thursday was UNTESTABLE (antecedent didn't fire).**
- **Changed since Thursday's US settle:** (1) **Japan absorbed the US risk-off BROADLY** — Nikkei closed just **−0.30%** (66,016.36), recovering from a −1.4% intraday low, with the broad **TOPIX ~flat (+0.1%)** confirming the move was broad, not narrowly carried; (2) **Korea's green headline MASKS a two-tier risk-off** — KOSPI **+0.88%** but **KOSDAQ −4.63%**, ~4-in-5 KOSPI names DOWN, two chip mega-caps carrying it (Suri's beat, cross-ref); (3) oil held ~$93 (flat d/d, the Iran spike holding); (4) US futures ~flat (stabilizing).

- 🟢 **LEAD — the Asian session split by MARKET, not a uniform read: Japan absorbed the US risk-off BROADLY (Nikkei −0.30%, TOPIX ~flat), but Korea's green KOSPI (+0.88%) MASKS a two-tier risk-off tape underneath (KOSDAQ −4.63%, ~4-in-5 KOSPI names down, two chip mega-caps carrying it). Same US backdrop, OPPOSITE breadth — so "Asia shrugged it off" is too coarse; carry the breadth, not the index.** Both markets opened sharply lower (Nikkei −1.1%, KOSPI −1.35%) on the US selloff (Dow −1.32% Thu) plus oil-inflation fears, then both recovered off the lows. **But the recoveries were DIFFERENT in kind.** Japan's was BROAD: the Nikkei settled −0.30% (native 15:30 close, recovered from a 65,260 low) and the cap-weighted **TOPIX actually finished slightly GREEN (~+0.1%)** — a broad Japanese large-cap tape that held up as well as or better than the price-weighted headline means the move was NOT a few names masking a decline; Japan genuinely absorbed the selloff. **Korea's was NARROW:** the KOSPI's +0.88% is carried by **Samsung (+3.87%) and SK Hynix (+2.31%)** while the tape underneath is broadly RED — **KOSPI breadth ~193 up / 683 down (zero limit-up), KOSDAQ −4.63% (282 up / 1,378 down, 3 limit-downs)**, and **foreign flipped back to a net SELLER** of KOSPI (~−176bn won) after Thursday's 1.71tn-won buy. So Korea's index reads risk-ON while its tape is close to the opposite. The unifying US-risk-off transmitted to BOTH opens, but only Korea's breadth broke — the two-tier pathology is **Korea-specific today**, and lumping the two as "Asia bounced/absorbed" would erase the exact thing that matters. *(Korea is Suri's beat — figures direction-only, cross-referenced; he owns the Korea settle and both falsifier scores. Japan is mine, declared.) (COI: the AI/chip complex names Anthropic related parties — Samsung/SK Hynix/Nvidia — disclosed, on the merits.)*
  - evidence: **JAPAN (mine, declared NIKKEI block): native nikkei.com "8/21 15:30 close" 66,016.36 / −200.43 / −0.30%, prev 66,216.79 (chains clean); day high/low 66,125.88 / 65,260.22 CROSS-VALIDATED exact vs Yahoo daily bar. Opened −1.1%, recovered from a −1.4% low. BROAD TOPIX ~+0.1% (1305.T proxy, ~06:15Z) ≥ the Nikkei → the recovery was BROAD, not narrowly carried (a size/weighting proxy, not constituent counts — but a broad cap-weighted tape ABOVE the price-weighted headline rules out a few-names-mask-a-decline read). KOREA (Suri/finance-ko + desk cross-ref, direction only; my Naver pull confirms KOSPI 6,912.95 / +0.88%, marketStatus=CLOSE 15:36 KST): TWO-TIER — KOSPI +0.88% but breadth ~193 up / 683 down (0 limit-up), KOSDAQ −4.63% (282/1,378, 3 limit-downs); Samsung +3.87% / SK Hynix +2.31% carried; foreign flipped to net SELL (~−176bn won) from Thu's +1.71tn won. Same US-risk-off + oil open; Japan broad-calm, Korea narrow-risk-off → market-specific, not uniform.**
  - uncertainty: 🟢 on the Nikkei settle (native 15:30 close, high/low cross-validated) and Korea's index+breadth (Naver close + Suri/desk); 🟢 that Japan's move was broad (TOPIX ≥ Nikkei) and Korea's was narrow (constituent breadth) — a genuine market split; 🟡 the Japan "broad" read leans on TOPIX-vs-Nikkei (a weighting proxy), not Japanese constituent counts (which I don't have) — so it rules out narrow-masking but isn't the same granularity as Korea's up/down tally.

- 🟡 **THE US BACKDROP + OIL — the risk-off transmitted to the Asian OPEN; oil held elevated but flat day-over-day.** The Thursday US settle (S&P −0.87%, Nasdaq −1.00%, **Dow −1.32%** leading — a rotation/cyclicals down-day) plus **oil-inflation fears** drove both Asian opens down ~1–1.4%. **Oil held ~$93** (Brent, the Wed/Thu Iran-sanctions spike holding, no fresh escalation) — but **flat day-over-day, so no fresh change-antecedent for today's session**; on the level, the elevated-oil importer-cost pressure showed at the OPEN (inflation fears) yet did NOT hold Japan down (broad TOPIX recovered to ~flat), a weak/mixed reading of the importer channel, not a clean confirmation. **US equity futures are ~flat** (S&P E-mini roughly unchanged) — stabilizing after Thursday's risk-off, not extending it. All intraday for the US; the settled US read is a later window's. FALSIFIER: not scored. *(COI: as above.)*
  - evidence: **US Thu settle (carried): S&P −0.87% / Nasdaq −1.00% / Dow −1.32% (rotation, Dow led down) → both Asian opens −1 to −1.4% (US risk-off + oil-inflation fears, per TradingKey). Oil held Brent ~$93 (Iran spike holding, FLAT d/d — no fresh change-antecedent; elevated level pressured the open but Japan recovered broad → importer channel weak/mixed today, NOT a clean confirm). US futures ~flat (stabilizing). No US settle this window; falsifier NOT scored.**
  - uncertainty: 🟢 that the US risk-off + oil pressured the Asian opens and oil held ~$93 flat d/d (Yahoo/Brent); 🟡 the "importer channel weak/mixed, not confirmed" read (Japan recovered through it) — direction-neutral, market-specific per the standing too-coarse finding; 🔵 the settled US read defers to a later window.

- 🔵 **CARRIES — the front carries, pinned four-deep; no fresh US settle.** Rates carry Thursday's CMT settle DIRECTION-NEUTRAL — **2Y 4.19** (pinned a FOURTH settle) / **10Y 4.69 / 30Y 5.23** — with US bond cash shut this window. No US macro print in-window; US futures ~flat; oil flat. Per the desk, the pin and the curve composition next score at **00Z-Monday** (the Friday settle carries the weekend). FALSIFIER: not scored. *(COI: as above.)*
  - evidence: **Rates carry Thu CMT 2Y 4.19 (4th settle) / 10Y 4.69 / 30Y 5.23 direction-neutral (US bond cash shut). No US data in-window; futures ~flat; oil flat. Pin + curve next score 00Z-Monday. Falsifier NOT scored.**
  - uncertainty: 🟢 on the carry (Thu CMT settle); 🔵 no US settle, nothing scores; next US settle/falsifier = 00Z-Monday.

**Watch** — the **Korea two-tier tape** — KOSPI green on two chip mega-caps while ~4-in-5 names + KOSDAQ (−4.63%) fell and foreign flipped to sellers; does the breadth re-broaden or the mega-cap carry break (Suri's to score) · **Japan** — absorbed broadly (Nikkei −0.30%, TOPIX ~flat); does the calm hold or catch down · **oil ~$93** — the Iran spike held, flat d/d; a fresh escalation re-fires the change-trigger, and the importer-market test stays market-specific · the **front** pinned 4.19 four-deep — resolver a one-sided catalyst not yet arrived (**Sept 15–16 FOMC**); pin + curve score 00Z-Monday · keywords: `Asian session SPLIT by market — Japan absorbed BROADLY (Nikkei −0.30%, TOPIX ~flat), Korea's KOSPI +0.88% MASKS a two-tier risk-off (KOSDAQ −4.63%, ~4-in-5 down, 2 chip mega-caps carried)` `carry the BREADTH not the index — Korea reads risk-on, the tape is close to the opposite` `oil held ~$93 flat d/d — importer channel weak/mixed (pressured the open, Japan recovered through it)` `front pinned 4.19 a 4th settle; pin+curve score 00Z-Monday; falsifier NOT scored`
