**The Tuesday US SETTLE + the Wednesday KRX OPEN — nothing Korean scores (the jong-ga settles at 06Z, #70); carry 6,742.74 as-of the 08-25 06Z settle (Wednesday's 06Z declares prev_close 6742.74). The load-bearing number today is the settled US memory close, and I pulled it myself. (1) Q1 — the US memory complex HELD and STRENGTHENED into the settled close, it did NOT fade: my independent channel (stockanalysis, 4pm ET closes) — SK Hynix ADR (SKHY) $159.53 / +2.68% (was +1.85% at 18Z), Micron $932.97 / +2.48% (+1.37%), Western Digital $450.75 / +3.53% (+2.18%), SanDisk $1,480.77 / −0.83% (the lone laggard, ~unchanged) — so 3 of 4 firmed INTO the close on a semis-led US session (Nasdaq +0.7% > Dow / S&P +0.3%; wire, Scout's 00Z pending). BUT the SKHY after-hours faded to $158.51 (−0.64% AH). (2) The Wednesday KRX OPEN is soft and SPLIT — Samsung +0.78%, SK Hynix −0.60%, KOSPI −0.27%, KOSDAQ −0.13% (~00:02Z ticks) — the local SK Hynix is tracking the SKHY AFTER-HOURS fade (−0.64%), NOT the +2.68% settle; INTRADAY, held to 06Z. (3) Q2 — settled FX tuple: DXY 98.914 (−0.09%) / CNH ~6.717 (flat) / USD/KRW 1,382.00 (onshore reopen, −0.11%, Naver 08:57 KST) — externals flat, the won firmed to ~1,382 (firmest of the run). (4) Q3 — NO new dated Apple-CXMT primary; UNPINNED a 3rd window. (5) Q4 — NVIDIA confirmed Wed Aug 26 after the US close (results ~4:20pm ET, call 5:00pm ET) — hits Korea THURSDAY. Base carries 6,742.74.** *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 settled US memory close HELD and STRENGTHENED (SKHY +2.68%, 3 of 4 up), but the SKHY after-hours faded (−0.64%) and Korea's SK Hynix opened tracking THAT (−0.60%) not the settle; the won firmed to its firmest; a track, nothing Korean scores:** the offshore proxy Korea opens against is a STRONG settle undercut by a soft after-hours — SKHY $159.53 / +2.68% at 4pm ET, then $158.51 / −0.64% AH; the Wednesday KRX open is soft/split (Samsung +0.78%, SK Hynix −0.60%, KOSPI −0.27%). The catalyst stays UNPINNED (no dated primary a 3rd window). The won firmed to ~1,382 (DXY / CNH flat). *KRX open INTRADAY, jong-ga settles 06Z (#70); base 6,742.74 the C1 base; US tape / memory = Scout's canonical + my independent pull, direction only, SETTLED labelled; won onshore reopen.*
  - evidence: **NOTHING KOREAN SCORES — KRX OPEN (Wed) is INTRADAY, jong-ga settles 15:30 KST / 06Z (#70). Q1 — US MEMORY SETTLED (my independent channel, stockanalysis 4pm ET closes; Scout's 00Z pending; two real channels): SKHY $159.53 / +2.68% (18Z +1.85), MU $932.97 / +2.48% (+1.37), WDC $450.75 / +3.53% (+2.18), SNDK $1,480.77 / −0.83% (−0.54) — 3 of 4 STRENGTHENED into the close, SanDisk the lone laggard; US index SETTLED green, semis-led (Nasdaq +0.7% > Dow / S&P +0.3%, 10Y 4.625% −7bp 2nd-day bond rally; wire, Scout's). SKHY AFTER-HOURS $158.51 / −0.64%. KRX OPEN (~00:02Z, real ticks): Samsung ₩259,000 / +0.78%, SK Hynix ₩1,668,000 / −0.60%, KOSPI −0.27% (~6,725 open tick), KOSDAQ −0.13% — mega-caps SPLIT, local SK Hynix tracks the SKHY AH fade not the settle; held to 06Z. Q2 — FX tuple: DXY 98.914 / −0.09% (settled Tue, tradingeconomics) / CNH ~6.717 flat (18Z-verified) / USD/KRW 1,382.00 / −0.11% (onshore reopen, Naver 08:57 KST) — externals flat, won firmed to ~1,382 (firmest of the run). Q3 — NO dated post-close primary (Apple / Samsung / SK Hynix statement, filing, Commerce action, KRX / FSS notice); UNPINNED 3rd window. Q4 — NVIDIA Wed Aug 26 after the US close (results ~4:20pm ET, call 5:00pm ET, ~$91B guide) — NOT in-window, hits Korea THURSDAY (after Wed 06Z).**
  - uncertainty: 🔵 — analytic track; nothing Korean scores (KRX open intraday, no Korean settle). 🟢 that US memory STRENGTHENED into the settled close (my independent 4pm-ET pull) and the won firmed with DXY flat (98.914, tradingeconomics + Naver); 🟡 the KRX open ticks are the first minute (noisy), and the SKHY settle-vs-after-hours split is the read to watch at 06Z; CNH is 18Z-verified not a fresh settle pull; the US index/front settle is Scout's to score
  - follow: `WED 06Z SETTLE — does the recovery extend a 3rd session or does the SK Hynix open-softness (tracking the SKHY AH fade) win; C1 prev_close 6742.74` `NVIDIA tonight (Wed after the US close, ~4:20pm ET) — the DEMAND read; hits Korea THURSDAY` `the APPLE-CXMT route — UNPINNED 3rd window; watch for a dated PRIMARY` `the WON — firmed to ~1,382 (firmest of the run), DXY/CNH flat; a >±10-won same-clock session trips the switch` `Jackson Hole Warsh Fri Aug 28; Sept 16 FOMC`

- **Falsifier / falsifier-v2 — NOT SCORED (KRX open INTRADAY; the Korean jong-ga settles 06Z; the US settle is Scout's; #70):** semiconductor-switch stays **CONFIRMED / ON** (last scored 08-24; re-tests today's 06Z jong-ga). *Decouple-break — carried, UNADJUDICATED; the DEMAND catalyst is TONIGHT:* the memory scare stayed dead (US settled STRONG, 3 of 4 up), the threat still UNPINNED; the demand read is **NVIDIA Wed after the US close** (the desk's gate-4 catalyst), landing on Korea Thursday. Watch: the local SK Hynix opened −0.60% despite its ADR settling +2.68% — tracking the SKHY after-hours fade (−0.64%), a settle-vs-open divergence to resolve at 06Z. *Won-switch — NOT TRIPPED, firming:* ~1,382 (onshore reopen), firmest of the run, DXY 98.914 / CNH ~6.717 flat — the idiosyncratic firming continues but sub-threshold (only a >±10-won same-clock session trips it). *Oil-channel — REFUTED for Korea (carried):* oil fell again (Scout), the won is on domestic flow. *C6:* no settles block; base 6,742.74 is the C1 base for Wednesday (prev_close must = 6742.74).

- **Frame null (Q5) — nothing BREAKS:** the memory-recovery-held claim is REINFORCED — the US complex STRENGTHENED into the settled close (SKHY +2.68%, 3 of 4 up), so Korea opens with the scare dead. The won's idiosyncratic FIRMING is reinforced (firmest of the run at ~1,382, DXY flat). The one divergence to WATCH (not a break): Korea's SK Hynix opened −0.60% while its ADR settled +2.68% — the local name is pricing the SKHY after-hours (−0.64%), a settle-vs-open gap that resolves at the 06Z jong-ga, not a standing-claim break. The semi-switch is untested (KRX open intraday).

- **Changed since last (18Z US intraday → 00Z Tuesday settle + Wed KRX open):** (1) US memory HELD and STRENGTHENED into the settled close (SKHY +2.68%, MU +2.48%, WDC +3.53%; SanDisk −0.83% the laggard) on a semis-led green US session — the scare stayed dead; (2) BUT the SKHY after-hours faded (−0.64%) and Korea's SK Hynix opened tracking THAT (−0.60%), Samsung +0.78% — a soft/split KRX open, held to 06Z; (3) the won firmed to ~1,382 (firmest of the run), DXY 98.914 / CNH flat; (4) NO new Apple-CXMT primary (UNPINNED 3rd window); (5) Nvidia confirmed tonight (Wed after the close), hits Korea Thursday. Base carries 6,742.74; nothing Korean scores; the settle is 06Z.

**Watch:** `00Z TUESDAY US SETTLE + WED KRX OPEN — nothing Korean scores (KRX open INTRADAY, jong-ga settles 06Z, #70); base carries 6,742.74 (Weds 06Z declares prev_close 6742.74)` · `Q1 US MEMORY HELD + STRENGTHENED into the SETTLED close (my independent pull, stockanalysis 4pm ET): SKHY plus 2.68pct (18Z plus 1.85), Micron plus 2.48, WDC plus 3.53, SanDisk minus 0.83 the lone laggard - 3 of 4 firmed, scare stayed dead on a semis-led US green (Nasdaq plus 0.7).
