The Wednesday jong-ga — the recovery EXTENDED a 3rd session, but its CHARACTER CHANGED: today was MEGA-CAP-LED, not breadth-led. KOSPI closed 6,808.21 / +0.97% (jong-ga: Naver mobile API marketStatus=CLOSE, 15:34 KST; C1 chains exactly — 6,808.21 − 65.47 = 6,742.74). (1) The split my last window set up RESOLVED UP: SK Hynix opened −0.60% (tracking the ADR after-hours fade) and CLOSED +0.60% — a full intraday flip — while Samsung ran +0.78% open → +1.75% close; both mega-caps recovered, the open-softness did NOT win. (2) BUT the index rose on those two names while KOSDAQ was FLAT (−0.03%) — so this is a MEGA-CAP re-concentration, a DIFFERENT claim from the prior two sessions' strengthening breadth, NOT a third of it. (3) I flag two gaps honestly: the exact advancer/decliner count and the settled foreign flow I could NOT verify — every wrap I reached was DATE-CONTAMINATED (Aug 13 / Aug 25) and the Aug 26 close-check was not yet out; I caught the trap rather than launder a stale number, so the breadth claim rests on structure and the flow read is DEFERRED. (4) The won WEAKENED ~3 won intraday (~1,382 morning → 1,385.30 settle) on a flat dollar (DXY 98.99). (5) Nvidia reports TONIGHT after the US close — NOT this window, it reaches Korea THURSDAY; positioning into it is not a demand read. Base re-anchors 6,808.21. 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 recovery extended a 3rd session (+0.97%) but the CHARACTER flipped from breadth-led to MEGA-CAP-led; the SK Hynix open-softness recovered to +0.60% by the close; flows/breadth counts I could not verify and I say so: KOSPI 6,808.21 / +0.97% (jong-ga, Naver API marketStatus=CLOSE 15:34 KST; C1 chains to 6,742.74) — but KOSDAQ was FLAT (−0.03%) and the two chip names led (Samsung +1.75%, SK Hynix +0.60%), so today is a mega-cap RE-CONCENTRATION, not a 3rd breadth-repair session. The split resolved UP: SK Hynix flipped −0.60% open → +0.60% close, Samsung +0.78% → +1.75%. The won WEAKENED ~3 won (1,385.30) on a flat dollar. Jong-ga two-source frustrated by date-contamination this window (caught, not laundered) — Naver CLOSE + C1-chain + Scout's pending cross-ref carry it; US = Scout's, direction only. Nvidia is Thursday-for-Korea, positioning ≠ demand.

    • evidence: SETTLE (Naver mobile API, marketStatus=CLOSE, localTradedAt 15:34 KST — timestamp-verified): KOSPI 6,808.21 / +0.97% / +65.47, C1 chains EXACTLY to prev_close 6,742.74. KOSDAQ 826.87 / −0.03% (close). Constituents (jong-ga, CLOSE 15:35): Samsung ₩261,500 / +1.75% (open +0.78 → close +1.75), SK Hynix ₩1,688,000 / +0.60% (open −0.60 → close +0.60, a full flip) → Q2: the open-softness RESOLVED UP, both mega-caps recovered. Q3 BREADTH: MEGA-CAP-LED — index +0.97% while KOSDAQ FLAT (−0.03%), the two chip names carrying it; this SUPPORTS a mega-cap re-concentration claim, NOT a 3rd strengthening-breadth session (the exact up/down count I could NOT verify — wraps date-contaminated, Aug 26 close-check wrap not yet out — so the claim rests on structure, not a count). Q4 FOREIGN FLOW: UNVERIFIED — clean Aug 26 settle flows unavailable (wraps date-contaminated); intraday reads suggested the ongoing pattern (foreign selling, buyback + institution absorbing) but I do NOT assert a settle number. Q5 FX TUPLE (~06:34Z): USD/KRW 1,385.30 / +0.13% (Naver, 15:34 KST) / DXY 98.99 / +0.07% (tradingeconomics, Aug 26) / CNH ~6.72 flat (18Z-verified) — won WEAKENED ~3 won on a flat dollar. Semi-switch NA (+0.97% < ±2%; mega-cap-led). US = Scout's canonical.
    • uncertainty: 🟢 on the jong-ga (Naver CLOSE + C1-chains exactly), the split resolving up (constituent closes), and the mega-cap-led STRUCTURE (index vs flat KOSDAQ); 🟡 the exact breadth count and the settled foreign flow are UNVERIFIED (date-contamination; flagged, not laundered); the won-weakening is intraday-clean but sub-threshold; 🔵 US = Scout's, and Nvidia (tonight) reaches Korea Thursday
    • follow: the Aug 26 SETTLE FLOWS + breadth count — confirm when the close-check wrap posts; did foreign sell a 3rd session or flip NVIDIA tonight after the US close — the DEMAND read, reaches Korea THURSDAY; do NOT pre-score on positioning is the mega-cap re-concentration a one-day pause in the breadth repair or a reversal — watch KOSDAQ + the count next session the WON — weakened ~3 won today (1,385.30), DXY flat; a >±10-won same-clock session trips the switch Warsh Jackson Hole Fri Aug 28; Sept 16 FOMC
    • sources: Naver mobile API — KOSPI marketStatus=CLOSE 6,808.21 / +0.97% (15:34 KST); Samsung +1.75% / SK Hynix +0.60%; KOSDAQ −0.03%; USD/KRW 1,385.30 (Aug 26 2026) · Hankyung — KOSPI live index (native settles.source, Aug 26 2026) · tradingeconomics — DXY 98.99 / +0.07% (Aug 26 2026) · finance-ko 00Z — the split open + SKHY after-hours fade, base 6,742.74 (Aug 26 2026)

  • Falsifier / falsifier-v2 — SCORED (the settle exists and is owned): KRX WED SETTLE — KOSPI 6,808.21 / +0.97%, the recovery EXTENDED a 3rd session but MEGA-CAP-LED (Samsung +1.75 / SK Hynix +0.60 carrying it, KOSDAQ FLAT). Semiconductor-switch — NA (+0.97% < ±2%), stays CONFIRMED / ON: under threshold so it did not formally test, but today was chip-led (the mega-caps carried a flat-breadth tape) — the switch's signature, not against it. Decouple-break — UNADJUDICATED, and the demand read is TONIGHT (do not pre-score): the mega-caps led on positioning INTO Nvidia, which is expectations, not demand; the demand question gets its read at Nvidia (after the US close) reaching Korea Thursday — nothing today scores it. The Apple-CXMT threat stays UNPINNED (4th window). Breadth-repair — PAUSED, not confirmed a 3rd session: the prior two sessions' strengthening breadth did NOT extend — today reverted to mega-cap leadership (KOSDAQ flat); whether that is a one-day pause or a reversal is next session's read. Won-switch — NOT TRIPPED; the won WEAKENED today: ~1,385.30 (−3 won intraday) with DXY flat — an idiosyncratic move but the OPPOSITE direction from the recent firming and sub-threshold (only a >±10-won same-clock session trips it). Oil-channel — REFUTED for Korea (carried): the won is on domestic flow. C6: close 6808.21 / prev_close 6742.74 / native close-label / hankyung / 06:40Z, cb_level OMIT; C1 chained clean — prev_close 6742.74 is exactly Tuesday's close. Base: 6,808.21 (chain …6,742.74 → 6,808.21).

  • Frame null (Q6) — one claim is PAUSED, the frame is being RECONCILED this window: the "durable breadth repair" read did NOT extend to a 3rd session — today was mega-cap-led (KOSDAQ flat), a re-concentration — so that claim is PAUSED (a one-day pause or a reversal, next session decides), not broken. The won's idiosyncratic FIRMING did not extend either — the won WEAKENED ~3 won today — but that is sub-threshold noise, not a break. The semi-switch is intact (chip-led). Separately: I am RECONCILING finance-ko/frame.md this window per the desk — its base block was 4 sessions stale (showed KOSPI 6,912.95 vs the actual base), and I am refreshing every carried level to current with a PER-MARKET as-of date and compressing the 08-24→26 arc.

  • Changed since last (00Z Wed open → 06Z Wed settle): (1) the recovery EXTENDED a 3rd session (+0.97%, 6,808.21) but MEGA-CAP-led — Samsung +1.75 / SK Hynix +0.60 carrying it, KOSDAQ FLAT — a re-concentration, not a 3rd breadth-repair; (2) the split RESOLVED UP — SK Hynix flipped −0.60 open → +0.60 close, the open-softness did not win; (3) the won WEAKENED ~3 won (1,385.30), DXY flat; (4) flows + breadth count UNVERIFIED (date-contamination, flagged not laundered); (5) Apple-CXMT UNPINNED 4th window; Nvidia tonight → Korea Thursday. Base re-anchors 6,808.21; C1 chained clean.

Watch: 06Z KRX SETTLE — KOSPI 6,808.21 / plus 0.97pct (jong-ga verified marketStatus CLOSE 15:34 KST, C1 chains exactly to 6742.74), the recovery EXTENDED a 3rd session but MEGA-CAP-LED not breadth-led: Samsung plus 1.75 / SK Hynix plus 0.60 carrying it while KOSDAQ was FLAT (minus 0.03) - a re-concentration, a DIFFERENT claim from the prior two breadth-repair sessions · THE SPLIT RESOLVED UP - SK Hynix opened minus 0.60 (tracking the ADR after-hours fade) and CLOSED plus 0.60, a full intraday flip; Samsung plus 0.78 open to plus 1.75 close; the open-softness did NOT win. TWO GAPS I FLAG not launder: the exact advancer/decliner count and the settled foreign flow are UNVERIFIED (every wrap date-contaminated - Aug 13 / Aug 25 - the Aug 26 close-check wrap not yet out); the breadth claim rests on structure, the flow read is DEFERRED · THE WON WEAKENED ~3 won intraday (~1,382 morning to 1,385.30 settle) on a FLAT dollar (DXY 98.99 plus 0.07) - idiosyncratic but the OPPOSITE of the recent firming, sub-threshold, no trip. NVIDIA reports TONIGHT after the US close - NOT this window, reaches Korea THURSDAY; positioning into it is expectations, NOT a demand read (do not pre-score) · NEXT — is the mega-cap re-concentration a one-day pause or a breadth reversal (watch KOSDAQ + the count); Nvidia Thursday-for-Korea; frame.md reconciled this window; Warsh Jackson Hole Fri Aug 28; Sept 16 FOMC. Base 6,808.21
