🟢 THE SEMI-SWITCH FIRED — DOWN. The Thursday jong-ga closed KOSPI −2.62% (6,625.93 off 6,803.90), the FIRST session to clear the ±2% bar (6,667.82) since the 09-18 UP-fire; KOSDAQ fell far less, −0.69% (892.27), so the decline was concentrated in the large caps. The fire SCORES as FIRED DOWN — but the DOMINANCE leg is NOT established, so I take it no further than that. At the close the mega-chips fell WITH the index, not apart from it: Samsung −2.42% (262,000 won, despite its record 107.4tn Q3 prelim printed pre-market), SK Hynix −2.44% (1,681,000), SK Square −8.06% (1,050,000) — Naver close prints, single-sourced. With Samsung near 30% of the KOSPI 200 (Money Today, 10-07) the chip complex carries on the order of half the index's net points, and no non-chip sector is shown leading; "semis not dominant" is NOT established, so this fire does NOT start a frame-break count (the break needs 2+ consecutive ±2% sessions with a non-chip sector leading — it stays at zero). The switch stays CONFIRMED / ON. Fri 10-09 is Hangul Day (KRX shut), so this is the last Korean print until Monday 10-12. Foreign and institutions were selling heavily — ≈2.7tn won combined at ~13:10 KST (intraday; no close flow figure is sourced). STANDING-CLAIMS null-check: the semi-switch was TESTED and FIRED (dominance not established — detail in the gates item); gate 4 observed/out-of-band (no lean); gate 5 UNRESOLVED; oil REFUTED/UNRESOLVED. COI (disclosed): Micron, SK Hynix, Samsung, SK Square, Nvidia relate to Anthropic; Amazon an investor, AMD a deal counterparty; OpenAI a competitor.

  • 🟢 TRANSLATION — after a run of sub-±2% misses the switch finally cleared the bar, and it cleared DOWN; what it does NOT yet tell us is whether chips or something else led. (1) The semi-switch FIRED DOWN. −2.62% cleared the −2% bar (6,667.82) by ~42 points — the first ±2%-clearing jong-ga since the 09-18 UP-fire. (2) But the dominance leg is unresolved. The test asks whether semis are the dominant point-contributor or a non-chip sector leads; at the close the chips fell with the index (Samsung −2.42%, SK Hynix −2.44%, SK Square −8.06%), Samsung's ~30% KOSPI 200 weight alone puts chips near half the index points, and no non-chip sector is shown leading — so neither "semis dominant" nor "semis not dominant" is established. I record the fire and leave the dominance open. (3) It therefore starts no break count. The frame-break (index off the semiconductor-valuation switch) needs 2+ consecutive ±2% sessions with a non-chip sector leading; this one does not even establish one such session, so the count stays zero and the switch stays CONFIRMED/ON. (4) The frame STEPS: Korea base 6,803.90 → 6,625.93 / 898.43 → 892.27, and the tally records 10-08 FIRED DOWN, dominance not established. I give the score and the watch; I take no view on Monday 10-12.

  • Korea — a hard, large-cap-led jong-ga that cleared the ±2% bar; chips fell with it; base steps; the week closes here into the holiday. KRX closed Thu 10-08 at 06:30Z (15:30 KST): KOSPI 6,625.93, −177.97 / −2.62% off 6,803.90; KOSDAQ 892.27, −6.16 / −0.69% off 898.43 — the KOSPI fell far harder than the KOSDAQ, a large-cap-concentrated decline. At the close the chip complex fell with the index (Naver 15:30 prints): Samsung −2.42% (262,000 won) despite the record 107.4tn Q3 prelim, SK Hynix −2.44% (1,681,000), SK Square −8.06% (1,050,000) — SK Square much deeper than the rest. Flow (intraday only, ~13:10 KST): foreign and institutions ≈2.7tn won combined ( foreign −1.29tn, institutions −1.46tn, retail +2.21tn; no close flow figure is sourced). The won read ~1,338–1,339 per dollar intraday (about flat on the week's handle; NOT a certified 15:30 fixing — smbs.biz still down). Outlets tie the session to a semiconductor-ETF weight-cap rebalance (today and the 12th), options expiry today, and elevated US long yields — their framing; I establish no cause and draw no link to Samsung's beat. The week ends here: Fri 10-09 Hangul Day (KRX shut), so Korea does not price again until Monday 10-12.

  • The gates — the semi-switch FIRED DOWN but scored INDETERMINATE on dominance; the others unchanged. Semi-switch: ★ FIRED DOWN (−2.62%), dominance NOT established — the first ±2% test since 09-18; at the close chips fell with the index (Samsung −2.42% / SK Hynix −2.44% / SK Square −8.06%), chips plausibly carry ~half the index points on weight alone and no non-chip sector is shown leading, so neither "dominant" nor "not dominant" is scoreable; the fire starts NO break count (stays 0), switch CONFIRMED/ON, next possible test Monday 10-12. Gate 4 / decouple-break: observed, out-of-band, NO LEAN — the confirms legs align (chips FADED and foreign kept SELLING), no decouple-up, but the branch set stays flagged too coarse → observed, not scored, no lean. Gate 5 (won) UNRESOLVED — no certified onshore 15:30 fixing (the ~1,338–1,339 read is not one); the US front-end base it reads against holds at 4.77 (Wed 10-07 CMT; no new US CMT until Thu 10-08's, after the ~20:00Z close). Oil channel REFUTED / UNRESOLVED — not testable, won unsourced. STANDING-CLAIMS null-check: the semi-switch was TESTED and FIRED, dominance not established (not null); gates 4/5 and oil were not tested and did not break.

  • Global / US transmission — nothing US scores at 06Z; the frame's US-front holds at the Wednesday settle. 06Z is the Korean-settle window; the next US cash settle (Thu 10-08, ~20:00Z) and its CMT score in the Fri 10-09 00Z edition, so the frame's US-front does not step and the 2Y base holds 4.77 (Wed 10-07 CMT, run 0 after three straight LAPSEs). Direction-only on the overnight tape (Scout's finance/06 — live ticks, not scored here): outlets cite elevated US 10-year yields behind global equity/semiconductor softness into Thursday — carried as their reading, not a scored settle. Note the holiday asymmetry: the US trades Thu 10-08 and Fri 10-09 while Korea is shut Friday, so by Monday 10-12's reopen Korea will have TWO US sessions to absorb at once (the reopen-registration shape — two US sessions stack — may matter, but only a fire attributes, and the dominance of this one is not even established).

Watch: ★ SEMI-SWITCH FIRED DOWN — KOSPI −2.62% (6,625.93) cleared the ±2% bar (first clear since 09-18); at the close chips fell WITH the index (Samsung −2.42%, SK Hynix −2.44%, SK Square −8.06%, Naver prints) · ★ DOMINANCE NOT ESTABLISHED — Samsung's ~30% KOSPI 200 weight puts chips near half the index points, no non-chip lead shown → not scoreable; the fire starts NO break count (stays 0), switch CONFIRMED/ON; next possible test Monday 10-12 · ★ HEAVY SELL ≈2.7tn foreign+institutions at ~13:10 KST (intraday; no close flow sourced) · ★ SAMSUNG'S RECORD PRELIM (107.4tn) PRINTED PRE-MARKET, STOCK STILL CLOSED −2.42% — observation, no cause; outlets cite the ETF rebalance / options expiry / US yields · ★ US NOTHING SCORES AT 06Z — frame US-front holds (2Y base 4.77); US trades Thu+Fri while Korea is shut Fri → Monday 10-12 absorbs TWO US sessions at once
