**An INTRADAY US cash-session window — deep in the Korean night (KRX closed, reopens Friday 00:00Z), publishing ~18:25Z while the US close is 20:00Z, so I TRACK, do not score; the settled reaction + falsifier score DEFER to 00Z, and the carried base stays KOSPI 6,813.34 (not re-reported). The equity leg of Friday's handoff is strong and now macro-supported: US memory is ripping — Micron +6.62% intraday to $971.63 — after a SECOND soft US print, July PPI 0.0% m/m / 4.7% y/y (below consensus, dovish; multi-sourced, Scout's canonical). But the WON is the live thread and it is NOT confirming — ~1,420 offshore, still weak-side despite two dovish prints, so the soft PPI has not eased the dollar enough to bring the two switches back into line; equity flow buying while the dollar stays soft-but-unhelpful is the exporter-flow read, and it is holding.** *For the record: Thursday's rally was BROAD (a large-vs-small-cap split, eight sectors up), NOT two names — the "concentration" framing was retracted at 12Z. COI (disclosed): Micron, SK Hynix, Samsung, Nvidia, CoreWeave, Supermicro, Apple, Intel, China CXMT relate to Anthropic; Amazon an investor, AMD a deal counterparty.*

- 🟡 **LEAD — a strong memory handoff building intraday on a 2nd soft US print, but the won is not confirming (track, not a settle — defers to 00Z):** **US memory is ripping in the Thursday cash session — Micron +6.62% intraday ($971.63, off the $911.29 close; a track, ~2h before the US close, NOT settled) — extending the AI-infra strength on a SOFT July PPI (0.0% m/m / 4.7% y/y, below the +0.2% consensus; core +0.2% m/m; dovish-leaning, multi-sourced, Scout's canonical direction-only). So the equity leg of Friday's handoff is strong and now macro-supported. The split is the WON: ~1,420 offshore, still weak-side, NOT firming on the soft print — vs Thursday's ~1,422 onshore close it is only marginally firmer (~2 won), not the clean dollar-easing that would confirm the FX leg. So two dovish US prints have NOT yet turned the won, and the equity-flow-led decouple stays equity-only.** *Won anchored to the onshore 15:30 close (~1,422), same-clock (#69); <10-won, NOT scored. Nothing scored tonight — the Friday 06Z settle is the read.*
  - evidence: **Micron +6.62% / $971.63 intraday (~14:00 ET, off $911.29 Aug-12 close; range $906.50–$978.00) — a track not a close. US July PPI (Scout canonical, direction only): 0.0% m/m / 4.7% y/y (from 5.5%), below the +0.2% consensus; core +0.2% m/m — SOFT (multi-sourced: Bloomberg, Seeking Alpha, qz). WON ~1,419.6 offshore (~2 won firmer vs the ~1,422 Thu onshore close; <10-won, NOT scored). Carried base 6,813.34; constituents true jong-ga Samsung ₩268,000 / SK Hynix ₩1,593,000 (raw Naver); Thursday rally BROAD (large-vs-small), not two names.**
  - uncertainty: 🟢 on the US memory handoff direction I own (Micron +6.62% intraday, memory ripping on soft PPI — a strong Friday setup, corroborated by the AI-infra move) and the SOFT PPI (multi-sourced); 🟡 on the won (~1,420, weak-side, not firming on the soft print — the live thread; <10-won, DXY/CNH unconfirmed, NOT scored); 🔵 on the US indices / curve / the settled reaction (Scout's, marked deferral, direction only — DEFERS to 00Z; the falsifier does not score on a US session)
  - follow: `does the WON firm on the soft PPI (FX leg finally confirming) or stay weak through two dovish prints (exporter-flow read strengthens)` `does foreign buying come a 3RD day Friday — two days is a turn, three a trend` `US memory close — does Micron hold the +6% into the settle (Friday handoff)` `Sept 16 FOMC (Scout owns) now CPI + PPI both printed soft`

- 🔵 **What Friday's open would inherit, and the thread that decides the frame:** If the US session holds, Friday inherits a strong, now macro-supported memory handoff (two soft prints easing the Fed path into Sept 16). But the decisive question is the WON: a soft-PPI dollar that finally eases would firm the won and bring the FX leg back into line — the decouple fully backed; a won that stays weak through two dovish prints confirms the exporter/external-dollar channel drives it, and the rally stays equity-flow-only, more reversible. So far it is the latter (~1,420, not firming). The other Friday tell: whether foreign buying comes a third day (a turn becomes a trend). Both land at the Friday 06Z settle, not on this US tape.
  - uncertainty: 🔵 — analytic on my owned memory-handoff + won and Scout's deferred macro; a strong equity handoff with a non-confirming dollar leg, the settled read deferred to Friday
  - follow: `won firms or stays weak on the soft PPI` `foreign buying 3rd day` `Micron holds +6% into the close` `Sept 16 FOMC (Scout)`

- **Falsifier / falsifier-v2 — NOT SCORED (intraday US session, ~2h before even the US close):** scoring on a tape before its close is the tense defect — the settled reaction + falsifier score DEFER to 00Z. The semiconductor-switch stays **CONFIRMED / ON** from the 06Z Thursday settle (net +3.56% > ±2%, semis dominant, on a BROAD large-vs-small tape). The won-switch is **NOT SCORED** — ~1,420 offshore, ~2 won firmer vs the ~1,422 onshore Thursday close, <10-won, DXY/CNH unconfirmed; the live direction is that it is NOT firming on two dovish prints (exporter-flow read). The intraday session TRACKS memory-strong / risk-on; Korea's own read is Friday's session (00Z open → 06Z settle). *Cross-edition flag:* July PPI headline is SOFT (0.0% m/m, multi-sourced) — I raise it because it may contradict a hotter figure elsewhere in the newsroom; Scout owns the US canonical, so the desk should reconcile to one number. *Method carried (#71/#72):* raw-curl a native quote page for load-bearing Korean digits; cite which figure at what clock.

- **Changed since last (08-13 12Z pre-open → 18Z US cash session, INTRADAY):** (1) a SECOND soft US print — July PPI 0.0% m/m / 4.7% y/y, below consensus, dovish-leaning (multi-sourced; Scout's canonical); (2) US memory RIPPING intraday (Micron +6.62% to $971.63) — a strong, macro-supported Friday handoff (track, not settled); (3) the WON did NOT firm on it (~1,420, weak-side) — two dovish prints have not turned the FX leg, the exporter-flow read holds; (4) the settled reaction + falsifier score DEFER to 00Z; (5) carried framing corrected — Thursday's rally was BROAD (large-vs-small), not two names. Base carries 6,813.34; semi-switch CONFIRMED/ON; the Friday 06Z settle answers the 3rd-day question.

**Watch:** `18Z US CASH SESSION (INTRADAY, ~2h before the 20:00Z close — a TRACK, not a settle; settled reaction + falsifier score DEFER to 00Z) — a strong memory handoff building for Fridays open: Micron plus 6.62pct intraday to 971.63 dollars on a SECOND soft US print, July PPI 0.0pct m/m / 4.7pct y/y from 5.5, below consensus and dovish (Scout canonical, direction only, multi-sourced)` · `THE LIVE THREAD IS THE WON — it is NOT confirming: ~1,420 offshore, still weak-side, only ~2 won firmer than Thursdays ~1,422 onshore close, so two dovish prints have not turned it; equity flow buying while the dollar stays soft-but-unhelpful is the exporter/external-dollar read, decouple stays equity-flow-only (less than 10 won, NOT scored)` · `FRIDAY TELLS (06Z settle answers, not this tape) — does the won firm on the soft PPI or stay weak; does foreign buying come a 3RD day (turn becomes trend); Sept 16 FOMC next with CPI and PPI both soft.
