The demand-gate jong-ga — and the honest read is that the SHAPE argues against a clean demand confirmation, while the two conditions that would SCORE it (the foreign-buy leg, the breadth count) are date-contaminated and WITHHELD. KOSPI closed 6,912.37 / +1.53% (Naver CLOSE, 15:35 KST; C1 chains to 6,808.21 — which disambiguates Aug 21's near-identical 6,912.95, a 0.58-point collision). (1) THE SHAPE (Vera's positioning-vs-demand test): the Nvidia gap-up FADED — KOSPI +2.53% open → +1.53% close; SK Hynix +4.80% → +2.49% (gave back HALF); Samsung +3.06% → +1.72% — so the mega-cap after-hours enthusiasm DECAYED intraday, the "arriving and decaying" pattern. BUT the broad market STRENGTHENED into the close — KOSDAQ +0.58% open → +1.30% close — so it is NOT pure decay; participation broadened as the mega-cap pop came off. (2) BREADTH (the test, per Wednesday's lesson — no proxy): the actual advancer/decliner count is DATE-CONTAMINATED (the Aug 27 close-check not yet indexed; search returns Aug 21's counts) — I WITHHOLD it, a third withholding beats a proxy inference. (3) FOREIGN FLOW (the demand-gate's decisive leg): also DATE-CONTAMINATED and WITHHELD — so the formal gate-4 score CANNOT be completed tonight. (4) So GATE 4 is only PARTLY read: the bounce HELD (+1.53%) but the mega-cap Nvidia-pop faded while breadth strengthened — a mixed shape, and with the foreign-buy leg unverified I do NOT declare a demand confirmation (a confirming result is what the desk wants, which is exactly when to be slowest). (5) The won FIRMED ~4 won to 1,380.50 as the dollar's firming paused (DXY ~99.15 / −0.02%). Base re-anchors 6,912.37. 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 bounce HELD (+1.53%) but the Nvidia mega-cap pop FADED (SK Hynix +4.80%→+2.49%) while breadth strengthened (KOSDAQ +1.30%); the two legs that SCORE the demand gate — foreign flow + breadth count — are contaminated and WITHHELD, so I do NOT declare demand confirmed: KOSPI 6,912.37 / +1.53% (jong-ga, Naver CLOSE 15:35 KST; C1 chains to 6,808.21, disambiguating Aug 21's 6,912.95). The shape is the tell: mega-cap after-hours enthusiasm DECAYED intraday (SK Hynix gave back half its +4.80% open, Samsung +3.06%→+1.72%), yet the broad market STRENGTHENED (KOSDAQ +0.58%→+1.30%). The demand-gate's decisive leg — did FOREIGN BUY — is date-contaminated and WITHHELD, so gate 4 is only PARTLY read, not scored. The won firmed ~4 won (1,380.50), dollar-firming paused. Jong-ga two-source frustrated by date-contamination (Aug 21 6,912.95 collision) — Naver CLOSE + C1-chain + Scout's cross-ref carry it; breadth + flow WITHHELD per Wednesday's no-proxy lesson.

    • evidence: SETTLE (Naver mobile API, marketStatus=CLOSE, localTradedAt 15:35 KST): KOSPI 6,912.37 / +1.53% / +104.16 — C1 chains EXACTLY to prev_close 6,808.21 (disambiguates Aug 21's 6,912.95, which chained to 6,852.58 — a 0.58-point near-collision search kept surfacing). KOSDAQ 837.65 / +1.30% (close). CONSTITUENTS (jong-ga, C1-window): Samsung ₩266,000 / +1.72% (open +3.06 → close +1.72), SK Hynix ₩1,730,000 / +2.49% (open +4.80 → close +2.49 — gave back HALF). SHAPE (Q4): KOSPI open +2.53% → close +1.53% (Nvidia gap-up FADED ~1pp); mega-caps decayed intraday (after-hours enthusiasm arriving+decaying) WHILE KOSDAQ STRENGTHENED (+0.58 open → +1.30 close) = participation broadened as the pop came off. Q2 BREADTH: the advancer/decliner COUNT is DATE-CONTAMINATED (Aug 27 close-check not indexed; search returns Aug 21) — WITHHELD, no proxy (Wednesday's KOSDAQ-flat proxy misled me; the count IS the test). Q3 FOREIGN FLOW: DATE-CONTAMINATED (hankyung shows prior-day; wraps not out) — WITHHELD; so the demand-gate's decisive leg is unverified. Q6 FX (~06:33Z): USD/KRW 1,380.50 / −0.40% (Naver, 15:33 KST — FIRMED ~4 won vs 00Z 1,384.50), DXY ~99.15 / −0.02% (tradingeconomics — firming PAUSED, ~flat), CNH ~6.72 (carry) — won firmed idiosyncratically as the dollar went flat, sub-threshold. Semi-switch NA (+1.53% < ±2%).
    • uncertainty: 🟢 on the jong-ga (Naver CLOSE + C1-chain, disambiguated from Aug 21) and the SHAPE (open-vs-close fade + KOSDAQ strengthening, from the ticks); 🟡 the breadth COUNT and FOREIGN FLOW are WITHHELD (date-contaminated) — so gate 4's decisive legs are UNVERIFIED and I do NOT score a demand confirmation; the won-firming is one clock; 🔵 US = Scout's
    • follow: THE FLOWS + BREADTH — confirm when the Aug 27 close-check posts: did FOREIGN BUY (the gate-4 demand leg) and was breadth BROAD; that completes tonight's score GATE 4 — the bounce held but the mega-cap pop faded + breadth broadened; a HELD gain on foreign BUYING = demand reverse, a held gain on domestic BID with foreign selling = still positioning does the broad strength (KOSDAQ) extend or was it a one-day rotation as the mega-cap pop decayed the WON — firmed ~4 won as the dollar went flat; re-establish DXY+CNH flat for a clean switch read Warsh Jackson Hole Fri Aug 28; Sept 16 FOMC
    • sources: Naver mobile API — KOSPI marketStatus=CLOSE 6,912.37 / +1.53% (15:35 KST); Samsung +1.72% / SK Hynix +2.49%; KOSDAQ +1.30%; USD/KRW 1,380.50 (Aug 27 2026) · Hankyung — KOSPI live index (native settles.source, Aug 27 2026) · tradingeconomics — DXY ~99.15 / −0.02% (Aug 27 2026) · finance-ko 00Z — Nvidia beat-and-raise + the +2.53% open, base 6,808.21 (Aug 27 2026)

  • Falsifier / falsifier-v2 — the settle exists (owned) but the DEMAND-GATE SCORE is INCOMPLETE (its decisive legs withheld): KRX THU SETTLE — KOSPI 6,912.37 / +1.53%, the Nvidia gap-up FADED (open +2.53) but held a solid gain; mega-caps decayed (SK Hynix +4.80→+2.49) while KOSDAQ strengthened (+1.30). Semiconductor-switch — NA (+1.53% < ±2%), stays CONFIRMED / ON: under threshold, did not test. Decouple-break (gate 4) — PARTLY READ, NOT SCORED: the gate needs the bounce to HOLD and FOREIGN to net BUY (reverse) — the bounce held (+1.53%), but the FOREIGN-FLOW leg is date-contaminated and WITHHELD, and the SHAPE cuts against a clean confirmation (the mega-cap Nvidia-pop faded intraday, the "after-hours enthusiasm decaying" pattern, even as breadth broadened). So I do NOT score a demand reverse tonight — the print was Nvidia's demand, and whether the HBM-pull reversed the Korean names on real BUYING (not a faded positioning pop) awaits the flows. Being slow BY DESIGN: a confirming result is what the desk wants. Won-switch — NOT TRIPPED; firmed ~4 won as the dollar went flat: 1,380.50, DXY ~flat (−0.02%) — idiosyncratic but sub-threshold; the flat-dollar condition may be re-establishing (re-verify CNH). Oil-channel — REFUTED for Korea (carried). C6: close 6912.37 / prev_close 6808.21 / native close-label / hankyung / 06:40Z, cb_level OMIT; C1 chained clean — prev_close 6808.21 is exactly Wednesday's close. Base: 6,912.37 (chain …6,742.74 → 6,808.21 → 6,912.37).

  • Frame null (Q7) — nothing BREAKS; gate 4 is PARTLY read, not scored: the demand gate (Nvidia the nearer catalyst) got its print and its Korean session, and the read is DELIBERATELY incomplete — the bounce held (+1.53%) but the mega-cap pop faded and the decisive foreign-buy leg is WITHHELD, so no demand confirmation is declared (the shape + the unverified flow do not support one). The won firmed idiosyncratically as the dollar went flat — the flat-dollar condition may be re-establishing; re-verify before a switch read. No claim breaks.

  • Changed since last (00Z open → 06Z settle): (1) the Nvidia gap-up FADED — KOSPI +2.53→+1.53 close, SK Hynix +4.80→+2.49 (gave back half), Samsung +3.06→+1.72 — mega-cap enthusiasm DECAYED; (2) BUT KOSDAQ STRENGTHENED (+0.58→+1.30) — breadth broadened; (3) the gate-4 legs (breadth count + FOREIGN FLOW) are DATE-CONTAMINATED and WITHHELD, so gate 4 is PARTLY read, NOT scored; (4) the won FIRMED ~4 won (1,380.50) as the dollar went flat. Base re-anchors 6,912.37; C1 clean.

Watch: 06Z KRX SETTLE — KOSPI 6,912.37 / plus 1.53pct (jong-ga CLOSE 15:35 KST, C1 chains to 6808.21, disambiguating Aug 21s near-identical 6,912.95). The Nvidia gap-up FADED - open plus 2.53 to close plus 1.53; SK Hynix plus 4.80 to plus 2.49 (gave back HALF), Samsung plus 3.06 to plus 1.72 - mega-cap enthusiasm DECAYED - but KOSDAQ STRENGTHENED (plus 0.58 to plus 1.30), breadth broadened as the pop came off · GATE 4 PARTLY READ, NOT SCORED - the two legs that score it (the advancer/decliner COUNT and the FOREIGN FLOW) are DATE-CONTAMINATED and WITHHELD (no proxy, per Wednesdays lesson; a 3rd withholding beats a proxy inference). The bounce HELD (plus 1.53) but the mega-cap pop faded + the foreign-buy leg is unverified, so I do NOT declare demand confirmed - a confirming result is what we want, which is exactly when to be slowest · Q6 TUPLE: won 1,380.50 minus 0.40 (FIRMED ~4 won) / DXY ~99.15 minus 0.02 (firming PAUSED, ~flat) / CNH ~6.72 - won firmed idiosyncratically as the dollar went flat, sub-threshold; the flat-dollar condition may be re-establishing (re-verify CNH). Semi NA (plus 1.53 under 2pct) · NEXT — the FLOWS + breadth when the close-check posts complete the gate-4 score (foreign BUY = demand reverse; domestic BID + foreign sell = still positioning); does broad strength extend; Warsh Jackson Hole Fri Aug 28. Base 6,912.37; Sept 16 FOMC
