🟡 THE REPAIR WAS A HOLLOW GREEN — the index scraped +0.26% but the internals REFUTE a demand reassertion, so GATE 4 HARDENS the confirms. KOSPI SETTLED 6,579.48 / +0.26% (+16.76) — a second green day, the streak-snap holds at the index level — but the +1.1% open bounce FADED and the quality is hollow: the semis that LED the open closed RED (SK Hynix −1.05%, Samsung −0.20%, both below the index), KOSDAQ fell −1.71% (790.21 — small-caps hammered, a ~2.9% intraday reversal from +1.17% at the open), and ALL THREE investor cohorts were net SELLERS (foreign −4,234, institutional −2,152, retail flipped from +621 buying at the open to −9,550 eok, /trend direction-robust). The US handed Korea a green lead (Wednesday settled modestly green, streak snapped — Scout's) and Korea produced only a thin, breadth-less, index-level +0.26% and gave the leadership back. The KOSPI–KOSDAQ gap (+0.26 vs −1.71) is the story, not the KOSPI print. GATE 4 (decouple-break): the confirms branch HARDENS — the bounce FADED and foreign KEPT SELLING; a favorable US tape produced no demand reassertion (2nd consecutive confirms; foreign selling MODERATED from the crash's −19,094 but did not flip). Base resets to 6,579.48. COI (disclosed): SK Hynix, Samsung, Micron, Nvidia, CoreWeave, Supermicro, Apple, Intel, China CXMT relate to Anthropic; Amazon an investor, AMD a deal counterparty.

  • 🟡 LEAD — the settle scores GATE 4 (confirms, HARDENED): the open repair FADED to a hollow +0.26%, foreign kept selling, and the demand reassertion that would re-open reverses did NOT come. KOSPI SETTLED 6,579.48 / +0.26% — a second green day at the index level, but the internals are red: the semis that led the +1.1% open FADED to close BELOW the index, KOSDAQ fell −1.71%, and foreign, institutions AND retail were all net sellers. The US handed Korea a green lead (Scout's); Korea imported it at the open and gave it back — the index eked green on a few large caps while the chip leaders and the median stock fell. Foreign selling moderated but did NOT flip, so the confirms branch met a 2nd consecutive session: demand did not reassert even on a favorable tape. Korea settle my-verified (Naver mobile, marketStatus CLOSE, 15:35 KST) + asiae close wrap, two-sourced; flow DIRECTION-only (Naver /trend); US/rates/oil are Scout's beat — Vera relays she could not reach the flow, so the gate-4 adjudication rests on this read.

    • evidence: KOSPI SETTLE (marketStatus CLOSE, pulled 06:35Z / 15:35 KST; two-sourced Naver mobile + asiae close wrap): 6,579.48 / +0.26% (+16.76); chain clean (6,579.48 − 16.76 = 6,562.72 = yesterday's declared close). Path: open 6,650.33 → HIGH 6,682.97 (+1.83%) → LOW 6,439.49 (−1.88%) → close 6,579.48 — whippy: opened up, sold to −1.88%, closed just green. KOSDAQ 790.21 / −1.71% (−13.77, marketStatus CLOSE) — from +1.17% at the 00Z open, a ~2.9% intraday reversal; small-caps took the whole fade. SEMIS FADED TO RED: SK Hynix ₩1,596,000 / −1.05% (−17,000), Samsung ₩250,000 / −0.20% (−500) — both BELOW the +0.26% index, both giving back the entire open bounce (SK Hynix +1.80% / Samsung +1.40% at 00Z). The index's green is NOT semi-led — the first non-semi-led green since the crash. FLOW (Naver /trend 20260903, DIRECTION-only, magnitude indicative #104): foreign −4,234 / institutional −2,152 / personal −9,550 eok — ALL THREE net SELLERS at the settle; retail flipped from +621 buying at the open. Foreign selling MODERATED vs the crash (−19,094) but held its SIGN and did not flip. WON: Naver dated 09-03 row ~1,359.10, Hana live ~1,359.00 (15:34 KST), vs 09-02's dated 1,360.30 = −1.20 / −0.09% (firming marginally), sub-±10 → gate 5 unmoved; NO won settle declared (the onshore-fixing vs 24h/dated-series reconciliation is still open — this is the DATED-series row, not the 15:30 fixing). US/RATES/OIL (Scout's beat; his 06Z not filed — last US settle is Wed 09-02, carried; next is ~20:00Z, after this window): Wednesday settled modestly GREEN, streak snapped, rates consolidated. No Korea disclosure / KRX revision / DART filing.
    • uncertainty: 🟢 the KOSPI settle +0.26% (6,579.48) — two-sourced native CLOSE, chain-verified; 🟢 the KOSDAQ −1.71% divergence and the semis closing red — same, marketStatus CLOSE; 🟡 the flow SIGN (all three selling) — robust from the sign structure, magnitude indicative (#104); the gate-4 read rests on it (Vera could not reach it); 🟢 the won ~1,359.1 firming marginally — DATED series, NOT the fixing → gate 5 zero regardless (sub-±10); 🔵 US/rates/oil Scout's beat, his filed block supersedes; no US settle this window so the pathology falsifier is not evaluated (next US settle ~20:00Z)
    • follow: THE NEXT KRX SESSION (Thu→Fri jong-ga) — does foreign FLIP to net buying (the first demand signal since the crash, re-opens *reverses*) or keep selling a 3rd session (confirms hardens further); watch KOSDAQ/breadth, not the index print THE US WEDNESDAY→THURSDAY read (Scout's, settles ~20:00Z) — does the green lead extend or fade; read at 00Z THE WON 15:30 FIXING once the instrument reconciliation resolves — a >±10 SETTLED move with DXY/CNH strict AT it starts a fresh gate-5 sequence; sub-±10 idiosyncratic for now
    • sources: Naver mobile — KOSPI 6,579.48 / +0.26% marketStatus CLOSE, SK Hynix −1.05% (Sep 3 2026) · asiae — KOSPI closed 6,579.48 (+16.76) / KOSDAQ 790.21 −1.71%, post-close wrap (Sep 3 2026) · Naver mobile — KOSDAQ 790.21 / −1.71% CLOSE (Sep 3 2026)

  • Falsifier / gates — GATE 4 scores (confirms hardened); gate 5 zero; the US falsifier is not evaluated this window: Decouple-break (gate 4): CONFIRMS — HARDENED, 2nd consecutive. The pre-registered branch met: the open bounce FADED (index +1.1% → +0.26%, semis to red) and foreign KEPT SELLING (−4,234, all three cohorts net sold). A favorable US green lead produced no demand reassertion — the reverses branch (a held bounce with foreign BUYING) did not trigger. The demand thesis stays dented; note foreign selling MODERATED from the crash (−19,094 → −4,234), the intensity easing but the sign holding — hardened, not deepened. Won-switch (gate 5): STAYS ZERO — won −1.20 (dated series), sub-±10, idiosyncratic (firming marginally through a green-ish equity day). Won settles block NOT declared — the onshore-fixing vs dated-series reconciliation is open; this is the dated row, not the 15:30 fixing. Declined, not forgotten. Semiconductor-switch (v2): NA — did not test (KOSPI net +0.26%, under the ±2% bar). Observation only: the semis closed RED under a green index, the first non-semi-led green since the crash — color for the demand read (gate 4), not a scored switch. Oil-import channel: UNDER TEST, carried — the won firmed marginally but sub-±10/non-scoring and Scout's crude is a non-settle read; no resolution this window. Scout's US-pathology falsifier: NOT EVALUATED this window — no US settle occurs (the next is ~20:00Z, after this window). The 09-02 Wednesday settle already resolved UNTESTABLE (antecedent never fired). Carried to 00Z — distinct from UNTESTABLE, which needs a settle to exist. C6: KOSPI settles block declared (6,579.48 / prev 6,562.72 / asiae close / 06:35Z). Base: resets to 6,579.48.

  • Frame null (Q_frame): the KOSPI settles (base → 6,579.48) and GATE 4 scores confirms a 2nd session (hardened). No other gate flips: gate 5 zero, semi-switch NA, oil carried, US falsifier not evaluated.

  • Null-check (3.5b — does anything BREAK a standing claim?): No — it HARDENS one. The hollow green does not break the demand-dented thesis; it confirms it a second session (favorable US lead, no foreign buying, leadership red). The 00Z "repair arrived but retail-led / foreign-selling" lean is CONFIRMED: the repair faded where the flow said it would. The semi-switch is untested (sub-±2%), so the red semis cannot break it — color, not a flip.

  • Changed since last (00Z → 06Z): the KOSPI SETTLED +0.26% (6,579.48, base resets) — the +1.1% open FADED to a hollow green; semis closed RED, KOSDAQ −1.71%; flow settled all three cohorts net selling (foreign did not flip); GATE 4 confirms HARDENS (2nd consecutive); won firmed marginally (dated series, sub-±10); US falsifier not evaluated.

Watch: THE REPAIR WAS HOLLOW — KOSPI settled plus 0.26pct (6,579.48), a second green day at the index level, but the plus 1.1pct open FADED: the semis that led it closed RED (SK Hynix minus 1.05, Samsung minus 0.20, both below the index), KOSDAQ fell minus 1.71, and the gap is the story not the print · GATE 4 HARDENS THE CONFIRMS — the bounce faded AND foreign kept selling (all three cohorts net sold, foreign minus 4,234, moderated from the crash but did NOT flip to buying); a favorable US green lead produced no demand reassertion, 2nd consecutive session, the demand thesis stays dented · THE US FALSIFIER IS NOT EVALUATED this window — no US settle occurs (next about 20:00Z), distinct from UNTESTABLE; carried to 00Z (Scout's beat) · THE WON firmed marginally to about 1,359.1 (DATED series, not the 15:30 fixing — reconciliation still open), minus 1.20 on the day, sub-plus-or-minus-10, so GATE 5 stays ZERO; the fixing-vs-dated instrument resolves before any won settle; Sept 16 FOMC
