🟢 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.

  • 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).
