## Desk frame
- **Held:** Korea's two switches are the **won level** and **semiconductor valuation**, both externally set — plus a **live oil/Middle-East tail** (WTI ~$73.07). This window resolves both Falsifier v2 tests: **semi-switch NA** and **won-switch session-2 did not confirm** (below).
- **Falsifier (v2) — the session-2 read:**
  - **Won-switch session-2 → NOT confirmed.** Wednesday's domestic-strength signal (won −29.7 to a 1,498.5 onshore fixing, DXY+CNH flat) did **not** extend: Thursday the won was **flat (~1,505.88, +0.04%, ~7 won *weaker* than Wed's fixing)** with DXY soft (−0.16%) and CNH flat. A >±10-won firming did not repeat, so the 2-consecutive-session trip **fails** — Wednesday's firming was a **one-session reaction** (the record-surplus print), not a new domestic-strength *leg*. The won stays primarily the **external dollar ceiling**. *Caveat: this is a TE snapshot — the same-clock 15:30 onshore Yonhap [FX] fixing was RSS-lagged at publish; re-check the verdict against it (I read it as not-confirmed).* 
  - **Semi-switch → NA.** The KOSPI *settled ~+0.26%* — inside the ±2% gate — so the test does not run, despite a violent intraday (open +3.31%, midday −2%). 
- **Contested:** AI chips — **global de-rate vs Korean rebound**. *De-rate* — **Nvidia shed ~$1tn of market cap** back toward pre-AI-boom valuation ([Yonhap](https://www.yna.co.kr/view/AKR20260709042000030)) vs *Korean demand/rebound* — Samsung **+3%** and SK Hynix **+7%** rebounded into the Korea close (Hynix ADR ~7× oversubscribed) ([Trading Economics](https://tradingeconomics.com/south-korea/stock-market)). The two diverged today — the US megacap de-rated while Korea's memory names bounced.
- **Suppressed → PROMOTED (carry):** oil/Middle-East stays live — WTI ~$73.07 on the US–Iran exchange (ceasefire in doubt); it is transmitting into Korean import/grocery prices and props the dollar (a won headwind). KTB 3y rose to ~3.813%. (Scout's `finance` leads.)
- **Changed since last:** **A wild session ended slightly UP — and the won-switch trip failed to confirm.** After the +3.31% open, the **KOSPI faded to the 7,100s (~−2%) midday, then recovered to close ~+0.26% (~7,265.63)** — a ~5% intraday range — with **Samsung +3% / SK Hynix +7% rebounding into the close** (a memory bounce against a global AI de-rate that saw **Nvidia lose ~$1tn**). Crucially, the **won-switch session-2 did NOT confirm** — the won went flat (~1,505.88), so Wednesday's domestic-firming was a one-off, and the frame's tentative "won gaining a domestic-strength leg" is **not** established. Oil paused to ~$73.07; China's June PPI ran **+4.1%** (4-year high), a reflation cross-signal.

- 🟢 **KOSPI settled ~+0.26% (~7,265.63) after a violent whipsaw — the +3.31% open faded to the 7,100s, then chips rebounded it into the close.** The session was wild but ended slightly higher: the index opened +3.31% (7,486.64), **reversed to the 7,100s (~−2%) by midday**, then **recovered to close ~+0.26% at ~7,265.63** as memory names turned up — **Samsung +3%, SK Hynix +7%** into the bell (with the Hynix ADR ~7× oversubscribed underneath). For a downstream agent: this is a **stabilization after "Black Wednesday," not a trend reversal** — a ~5% intraday range shows the volatility is still extreme. Per **Falsifier v2**, the **settled ~+0.26% is inside the ±2% gate, so the semi-switch test is NA** — the day was not a clean semiconductor-switch signal. Note the **cross-check discipline**: post-settle, two sources agree on the **direction — a modest gain** — though not the exact level. **Yahoo ^KS11 ~7,265.63 (+0.26%, with the *correct* prior close 7,246.79)** is the primary; **Trading Economics ~7,285.62 (+0.54%)** corroborates the up-direction ~20 pts higher (TE has a staleness history — see Black Wednesday). The **pre-settle** investing.com print (7,190/−0.78%) is discarded, and **Yonhap's session-close is still RSS-lagged — a next-window cross-check**. After Wednesday's stale-TE error I did not rely on a lone print, and I confirmed the clock was past the 06:30Z close before treating this as the settle.
  - evidence: two-source settle — [Yahoo Finance ^KS11: post-settle ~7,265.63 vs correct prior 7,246.79 = +0.26%](https://query1.finance.yahoo.com/v8/finance/chart/%5EKS11?interval=1d&range=2d) and [Trading Economics KOSPI: ~7,285.62 (+0.54%), Samsung +3% / SK Hynix +7% rebounded (July 9)](https://tradingeconomics.com/south-korea/stock-market); the intraday fade to the 7,100s carried from the 00Z-window session
  - uncertainty: post-settle Yahoo (correct prior close) reads +0.26% and is the primary; TE (+0.54%) corroborates the up-direction but sits ~20 pts higher (TE staleness history — Black Wednesday); investing.com's pre-settle 7,190/−0.78% is discarded; Yonhap session-close is the **next-window cross-check** (still RSS-lagged); KOSDAQ close not yet cleanly sourced. Semi-switch NA is robust across all candidates (all inside ±2%)
  - follow: `KOSPI settle +0.26 7265 recovered from 7100s midday July 9 · Samsung +3 Hynix +7 rebound close · semi-switch NA inside 2pct gate · Yonhap session-close cross-check`

- 🟡 **The won-switch session-2 did NOT confirm — Wednesday's domestic-strength firming was a one-off, so the frame's tentative "domestic won leg" is not established.** Falsifier v2's key open question resolved negatively: after Wednesday's −29.7-won onshore firming to 1,498.5 (DXY+CNH flat, a clean session-1 domestic signal), **Thursday did not extend it** — the won was **~flat at 1,505.88 (+0.04%, ~7 won weaker)** with DXY soft (−0.16%) and CNH flat. No second consecutive >±10-won domestic firming means the trip **fails the 2-session test**. For a downstream agent, the corrected read is: the won's mid-week strength was a **reaction to the record current-account/export print, not a durable regime change** — the won remains primarily on the **external dollar/Fed switch** (and the oil-driven dollar bid is the live headwind). This is the falsifier doing its job — killing a tentative signal that a single session had suggested. *Source caveat: on a TE snapshot; the same-clock 15:30 onshore fixing was RSS-lagged at publish — re-verify, though the flat direction is unambiguous.*
  - evidence: verified on an opened primary — [Trading Economics KRW: USD/KRW ~1,505.88 (+0.04%), DXY 100.91 (−0.16%), CNH ~flat (July 9)](https://tradingeconomics.com/south-korea/currency); Wednesday session-1 (1,498.5 / −29.7 onshore fixing) carried
  - uncertainty: 🟡 — the won read is a TE snapshot, not the same-clock 15:30 onshore fixing (RSS-lagged); the *direction* (flat, did-not-extend) is clear, but confirm the exact fixing when the wire prints

- 🔵 **A telling divergence: the global AI de-rate escalated (Nvidia −~$1tn) even as Korean memory bounced — with oil and China PPI as the cross-currents.** The frame's semiconductor switch showed a split today: globally the AI trade de-rated hard — **Nvidia shed ~$1 trillion in market cap**, back toward pre-AI-boom levels — yet **Korea's memory names rebounded** (Samsung +3%, Hynix +7%). For a downstream agent, this is the valuation-vs-demand split made concrete: the **US megacap/logic** side is where the de-rate is biting, while **Korean memory** (with the Hynix ADR heavily oversubscribed and China building its own AI stack that still needs DRAM/HBM) held. Layered on: **oil ~$73.07** (still transmitting to Korean prices), **KTB 3y up to ~3.813%**, and **China's June PPI +4.1% (a 4-year high)** — a regional reflation signal that complicates the disinflation read. The next reads: whether Korea's memory bounce holds Friday, crude's path, and the delayed Yonhap fixing/close cross-checks.
  - evidence: verified on opened primaries — Nvidia −~$1tn ([Yonhap: Nvidia market cap evaporates ~$1tn, valuation back to pre-AI-boom (July 9)](https://www.yna.co.kr/view/AKR20260709042000030)); Korean chip rebound from item 1 (TE); China PPI +4.1% ([Yonhap: China June PPI +4.1%, 4-year high (July 9)](https://www.yna.co.kr/view/AKR20260709010151072)); oil ~$73.07 carried
  - uncertainty: 🔵 — the Nvidia figure is a market-cap move (fast, continuous); the "US-logic de-rate vs Korean-memory hold" divergence is one session; China PPI's read-through to Korea is indirect
