**🟢 THE TUESDAY JONG-GA SETTLED, AND IT SPLIT: THE CHIP-HEAVY KOSPI CLOSED DOWN ON A SEMICONDUCTOR BREATHER WHILE THE KOSDAQ JUMPED — AND THE KOSPI MOVE WAS TOO SMALL TO TEST THE SEMI-SWITCH. The first jong-ga since Fri 10-02, pricing the stacked Fri 10-02 + Mon 10-05 US sessions + the SOFT Sept payrolls in one reaction off the frozen 7,003.74: KOSPI closed 6,941.39, −0.89% (dipped to a 6,897.38 intraday low below 6,900, recovered into the close); KOSDAQ closed 919.92, +2.98%, breaking 900.** The two indexes went **opposite ways** — a breadth divergence. **The semi-switch did NOT test: the KOSPI's −0.89% close is far inside the ±2% bar → NA ("did not test"), the FIFTH clean sub-±2% test since Chuseok** (09-29/09-30/10-01/10-02/10-06); it carries ON/UP, last fired 09-18. Because the close did not clear ±2%, the registration's cause-attribution clause (two US sessions stack; a fire scores direction + dominance only) never engages — there is no fire to attribute. **The drag was chip-specific; no cause is established.** Neither US session Korea priced today de-rated the chip valuation (Fri 10-02 FIRE/RESET, Mon 10-05 LAPSE). Korean desks attribute the chip softness (SK Hynix −3.48%, Samsung −2.17%) to caution before Samsung's Q3 preliminary earnings on **Thu 10-08** and to elevated US long yields weighing on chip multiples. That is their reading, and the second half is a US channel. Foreign and institutions **SOLD** (foreign ~−1.32tn won on the KOSPI, institutions ~−74bn), retail was the bid (~+570bn) and the KOSDAQ engine (semi-equipment/materials + secondary batteries). Regionally Korea was the **laggard** — Nikkei +1.05%, Taiex +0.22% both closed up — which locates the story in Korea's chip complex, not a regional risk-off. The frame steps: Korea base 7,003.74 → **6,941.39** / 893.29 → **919.92**, the Current-state arc, the semi-switch tally, and the co-move line; the US-front does NOT step (no US settle at 06Z). STANDING-CLAIMS null-check: semi-switch NA (did not test, carries ON/UP); gate 4 observed not cleanly branched; gate 5 UNRESOLVED; oil REFUTED/UNRESOLVED — none broke. *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-but-SPLIT jong-ga: the chip index took a breather on domestic pre-earnings caution, the broad market rotated up, and the move was too small to settle the one switch everyone is waiting on.** **(1) The semi-switch did NOT test — NA, the fifth clean sub-±2% test since Chuseok.** Per the desk's 10-02 registration the switch was **"TESTABLE — scores normally if the KOSPI close clears ±2% (NA otherwise)"**; the −0.89% close did not clear, so **NA — "did not test"**, carries ON/UP, untested since the 09-18 UP-fire. The cause clause (a fire is **"NOT attributable to a single US session … DIRECTION + DOMINANCE only"**, two US sessions stack) does not engage — no fire. **(2) The drag is chip-specific; its cause is not established.** Neither stacked US session de-rated the valuation. Native desks call it semis "taking a breather" and cite Samsung's Q3 prelim on Thu 10-08 plus elevated US long yields on chip multiples (SK Hynix −3.48% / Samsung −2.17%). That is their reading, and it names a US channel too. **(3) The breadth SPLIT is the signal.** KOSPI −0.89% vs KOSDAQ +2.98% (semi-equipment/materials + secondary batteries led the KOSDAQ); foreign + institutions sold the large-cap board while retail bought it and drove the KOSDAQ. This is a rotation OUT of the mega-cap chips, **not** a risk-off de-rate — regional peers closed up and Korea lagged only on its chip names. **(4) The won was about flat; gate 5 still UNRESOLVED.** After the close the won read live 1,342.00 per dollar, −0.04% (Naver; CNBC flat), not a certified fixing. Local commentary flags won strength as an exporter-earnings overhang, but the day's level shows no firmer won. Gate 5 stays UNRESOLVED.
  - uncertainty: 🟢 the close is firmly native-sourced — two allowlisted close-labelled primaries carry it to the point: etoday (KOSPI −62.35 / −0.89% / 6,941.39 close) and asiae (KOSDAQ +26.63 / 919.92 close / +2.98%), matching Scout's desk figure (Naver CLOSE = CNBC final 15:30 print) for cross-edition consistency; investing.com's KS11 (6,941.89) and TradingEconomics (6,935.18 / −0.98%) corroborate within ~0.1%; 🟢 semi NA is unambiguous — −0.89% is far inside ±2%; 🟡 the flow figures are the 13:39 native edaily intraday cut (foreign −1.32tn), not the final KRX settlement flow — direction is clear, the finalized magnitude is the pull; 🔵 the won is direction-only (no certified 15:30 fixing; smbs.biz still down).

- **Korea — the jong-ga settled DOWN on chips, UP on the broad market; base steps.** KOSPI **6,941.39** / −0.89% (−62.35 off 7,003.74; intraday low 6,897.38 below 6,900, recovered into the 15:30 auction) · KOSDAQ **919.92** / +2.98% (+26.63 off 893.29, reclaimed 900). Chip large-caps led the KOSPI down (SK Hynix −3.48%, Samsung −2.17%); KOSDAQ was carried by semi-equipment/materials + secondary batteries. **Flow (13:39 native intraday cut, finalized KRX flow is the pull):** foreign ~**−1.32tn won** and institutions ~**−74bn** net SOLD the KOSPI, retail ~**+570bn** net bought — a clean foreign+institution SELL / retail bid on Tuesday. Friday's sign stays DISPUTED; Tuesday's flow does not resolve it. Base steps 7,003.74 → **6,941.39** / 893.29 → **919.92**.

- **The gates — semi NA, gate 4 observed, gate 5 unresolved.** Semi-switch **NA** (−0.89% did not clear ±2%) → fifth clean sub-±2% test since Chuseok, carries **ON/UP** (last fired 09-18), still untested; cause clause never engaged (no fire). Gate 4 / decouple-break: the chip leg **faded** (semi weakness) **and** foreign kept **selling** — the *confirms*/caution pattern for the chip complex — but the broad market **decoupled UP** (KOSDAQ +2.98%, retail bid) and the index is sub-±2%, so this is a **rotation out of chips, not a broad de-rate**; the branch set remains TOO COARSE / out-of-band (09-22), carried as observation not a scored branch. Gate 5 (won) **UNRESOLVED** — won about flat (won live 1,342.00, −0.04%), no certified 15:30 fixing. Oil channel **REFUTED/UNRESOLVED**. The US front-end base the won reads against is unchanged at **4.84** (no US settle this window).

- **Global / US transmission — NO step this window; the mirror holds at the Monday LAPSE.** 06Z is not a US settle (US cash settles ~20:00Z), so the US-front paragraph and base-levels block do **not** move — they hold at Scout's Mon 10-05 read carried from 00Z: **NO FIRE → LAPSE, run 0** (Composite max +1.30% inside >1.50%), a record AI-led Composite that imported **no chip-valuation de-rate**; 2Y CMT base **4.84** (long-end-led bear steepening, 10Y 5.31 / 30Y 5.66). Elevated US long yields (~5.31–5.34%) were cited by Korean desks as a headwind for chip multiples today — a carried level, not a fresh move. **Co-move (Tue 10-06 settled Asian closes, controls, no cause):** Nikkei **+1.05%** / Taiex **+0.22%** — both up, Korea the laggard, which keeps today's story in Korea's chip complex rather than a regional risk-off. Mainland China still shut. **Frame step:** the co-move line refreshes to these Tuesday closes; the Korea base + Current-state arc + semi tally step; the US blocks hold. Ahead: Samsung Q3 prelim **Thu 10-08**; FOMC Sept-meeting minutes **Wed 10-07** (belief, not a CPI/PCE print).
