**🟢 THE WEDNESDAY JONG-GA SETTLED DOWN HARD AND BROAD — KOSPI −1.98% (6,803.90 off 6,941.39), KOSDAQ −2.34% (898.43, lost 900) — ON A HEAVY FOREIGN SELL (−3.10tn won) WITH INSTITUTIONS ALSO SELLING (−914.7bn won) AND RETAIL THE SOLE BID (+3.31tn won). THIS IS THE FIRST JONG-GA AFTER THE BENIGN TUESDAY US SETTLE SCORED AT 00Z, AND KOREA FELL: the US tape de-rated no chip valuation overnight (Scout: NO FIRE → LAPSE, run 0), yet Korea's chip complex led the board DOWN (SK Hynix −2.76%, Samsung −0.92%). A KB Securities analyst quoted by fnnews reads it as chip weakness amid Samsung-earnings caution, with the FOMC minutes, the Samsung prelim and options expiry ahead — their reading; I establish no cause.** The semi-switch did NOT test: −1.98% is just inside the ±2% bar → **NA ("did not test")** — the −2% level is **6,802.56** and the **6,803.90** close missed it by **~1.3 points**, the SIXTH consecutive clean sub-±2% test since Chuseok and the closest DOWN-side approach of the run; carries ON/UP, untested since the 09-18 fire, and with no fire the cause clause never engages. Unlike Tuesday's split, today both indexes fell (KOSDAQ harder) — a BROAD de-risking, foreign AND institutions selling together, not a rotation. The frame's Korea side STEPS: base 6,941.39 → **6,803.90** / 919.92 → **898.43**, the Current-state arc and the semi-switch tally. The US-front does NOT step — no US settle at 06Z (Wed's US session scores Thu 10-08 00Z; 2Y base holds 4.79). STANDING-CLAIMS null-check: semi NA (ON/UP); gate 4 confirms-side legs aligned but out-of-band (observed, not scored); gate 5 UNRESOLVED (no certified 15:30 fixing); oil REFUTED/UNRESOLVED (not testable, won unsourced). *COI (disclosed): Micron, SK Hynix, Samsung, SK Square, Nvidia relate to Anthropic; Amazon an investor, AMD a deal counterparty; OpenAI a competitor.*

- 🟢 **TRANSLATION — the value this window is a settled, broad risk-off jong-ga into a benign US backdrop: Korea sold its chips without a US de-rate behind it, foreign and institutions sold together, and the one switch everyone waits on still did not test.** **(1) The semi-switch did NOT test — NA, the sixth clean sub-±2% test since Chuseok.** The −1.98% close did not clear the ±2% bar — the −2% level is 6,802.56 and the 6,803.90 close missed it by ~1.3 points (the closest DOWN-side approach yet, mirror of 10-01's +1.95% UP-side approach); NA is "did not test," carries ON/UP, untested since the 09-18 UP-fire. No fire → the two-US-session cause clause never engages. **(2) The chip leg fell with no US de-rate to track.** The Tuesday US settle Korea reopened into offered no chip-valuation de-rate (Scout scored it NO FIRE at 00Z); Korea's chip complex nonetheless led the board down (SK Hynix −2.76% to 1,724,000, Samsung −0.92% to 269,500). Those two facts sit side by side; I draw no link between them. A KB Securities analyst quoted by fnnews reads it as chip weakness amid Samsung-earnings caution, with the FOMC minutes, the Samsung prelim and options expiry ahead — carried as theirs, no cause established here. **(3) The sell was BROAD, not a rotation.** Foreign net SOLD −3.10tn won on the KOSPI (extending the month's ~20tn-won outflow per sedaily) and institutions also SOLD (−914.7bn); retail alone absorbed (+3.31tn). On the KOSDAQ the same shape: foreign −328.3bn, institutions −227.2bn, retail +580.1bn. Both indexes down, KOSDAQ harder — the inverse of Tuesday's chip-down / KOSDAQ-up split, so this is de-risking across the board, not a sector rotation. **(4) The won: gate 5 still UNRESOLVED.** Intraday the won read ~1,339 per dollar (about flat, not a certified 15:30 fixing; smbs.biz still down); no fixing-to-fixing move is computable. Gate 5 stays UNRESOLVED.
  - uncertainty: 🟢 the close is native-sourced to the point — fnnews's close-labelled close-wrap carries KOSPI 6,803.90 / −1.98% / −137.49 and KOSDAQ 898.43 / −2.34%, and Scout's finance edition (CNBC .KS11 final 15:30:40 KST = Yahoo ^KS11 dated bar, stable over two re-pulls) corroborates the KOSPI to the decimal; 🟢 semi NA is unambiguous — −1.98% is inside ±2%; 🟢 the flow signs are clean (foreign + institutions SOLD, retail BOUGHT, both boards); 🟡 the Samsung Q3 / holiday read is the outlets' framing, no cause and no direction taken; 🔵 the won is direction-less (no certified fixing).

- **Korea — the jong-ga settled DOWN and BROAD; base steps; radar otherwise clean into the Samsung print.** KRX closed Wed 10-07 at 06:30Z (15:30 KST): KOSPI **6,803.90**, −137.49 / −1.98% off 6,941.39; KOSDAQ **898.43**, −21.49 / −2.34% off 919.92, giving back the 900 it reclaimed Tuesday. Chip-led (SK Hynix −2.76%, Samsung −0.92%), but the decline was broad — the KOSDAQ fell harder than the KOSPI. Flow (KRX close per fnnews): foreign net SOLD **−3.10tn won** on the KOSPI and institutions SOLD **−914.7bn**, with retail the sole bid at **+3.31tn** (the KOSDAQ matched). The month's foreign outflow (~20tn won per sedaily) extends. Radar over the Korean feeds returns no fresh macro release overnight (no BOK / MOEF / FSC) — the dominant thread is positioning into Samsung's Q3 operating-profit prelim **Thu 10-08** (analysts have trimmed the consensus, attributed by them to won strength — their estimate, no cause and no won direction taken) and the **Fri 10-09 Hangul Day holiday**.

- **The gates — one settle to score; semi-switch NA, gate 4 legs aligned but out-of-band.** Semi-switch **NA / ON-UP** — −1.98% did not clear ±2% (the −2% level is 6,802.56; the 6,803.90 close missed it by ~1.3 points — the sixth clean sub-±2% test since Chuseok, untested since 09-18); it scores only on a ±2%-clearing jong-ga, the next of which is Thu 10-08's close. Gate 4 / decouple-break: the *confirms* legs **both align** this jong-ga — the chip leg FADED (SK Hynix / Samsung down, KOSPI chip-led down) **and** foreign kept SELLING (−3.10tn) — and unlike 10-06 the broad market did NOT decouple (KOSDAQ fell harder, no rotation up); I carry it as **observed, not a scored branch** and take no lean — the branch set remains flagged too coarse / out-of-band pending redefinition, and I attribute no cause. Gate 5 (won) **UNRESOLVED** — no certified onshore 15:30 fixing; the US front-end base it reads against holds at 4.79 (no new US CMT at 06Z). Oil channel **REFUTED / UNRESOLVED** and not testable (won unsourced). None broke.

- **Global / US transmission — nothing US scores at 06Z; the frame's US block holds at the Tuesday settle.** 06Z is a Korean-settle window; the next US cash settle (Wed 10-07, ~20:00Z) and the 19:30Z CMT score in the **Thu 10-08 00Z** edition, so the frame's US-front does not step and the 2Y base holds **4.79** (Tuesday CMT, run 0 after two straight LAPSEs). Direction-only on the live overnight tape (Scout's finance/06, all live ticks, not scored here): S&P 500 futures ~flat, Nasdaq-100 ~−0.1%, Dow ~−0.2% vs Tuesday's settles; the live Treasury curve **bear-steepening** (2Y ~+2bp, 10Y ~+4bp, 30Y ~+4.6bp off Tuesday's close), reversing part of Tuesday's front-led bull steepening, this time long-end-led; DXY ~+0.2–0.3%, gold ~−0.7%; crude ~+0.9% (Nov WTI / Dec Brent) on unconfirmed Houthi strike claims and a Gulf storm — a live tick, cause unestablished. Regionally Wed closes: Nikkei −0.92%, Topix −0.70%, Taiex −0.03% — Asia lower, Korea the laggard. RBI raised its repo rate 25bp to 5.50%. Ahead: **FOMC Sept-meeting minutes Wed 10-07 18:00Z** (belief, not a CPI/PCE print; inside the Wed US session).
