**A US-intraday track — Korea shut since the 06:30Z jong-ga, US cash not closing til 20:00Z (after our ~18:45Z cutoff), so NOTHING scores (#70); carry 6,742.74 as-of the 06Z settle (Wednesday's 06Z declares prev_close 6742.74). The window's news is what did NOT happen and what is DATED next. (1) The memory scare stayed DEAD offshore: the SK Hynix ADR (SKHY) is +1.75% ($158.09, ~18:02Z live) and the US memory complex is firm INTO Nvidia — so Monday's rebound HELD and extended, and Korea opens Wednesday with the threat still rejected. (2) NO new dated primary on the Apple-CXMT route since 12Z — no Apple / Samsung / SK Hynix statement, no filing, no Commerce action, no fresh FT — so the CATALYST stays UNPINNED (the honest state to publish); the standing context only cuts further AGAINST the threat (a Senate letter set an Aug 21 deadline for Apple to reject CXMT / YMTC, Micron lobbies to DENY, CXMT is ~2–3 generations behind — a ceiling on Apple's stack even if approved). (3) The won is FLAT-to-FIRM through a two-day foreign exit — a verified same-clock 18:21Z tuple (won 1,383.05, DXY / CNH both flat) confirms externals genuinely flat at 18Z and the won dead-flat vs the 12:03Z 1,383.19 — so the idiosyncratic firming holds. (4) THE forward-look: NVIDIA reports Wednesday Aug 26 AFTER the US close (release ~4:20pm ET, call 5:00pm ET; ~$91B revenue guide) — a real DEMAND read for the decouple-break, and because it lands after the US close it hits Korea on THURSDAY, one clock AFTER Wednesday's 06Z jong-ga. 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 memory scare stayed DEAD offshore (SK Hynix ADR +1.75%, memory firm into Nvidia), no new Apple-CXMT primary (catalyst UNPINNED), the won flat-firm through the exit — and NVIDIA (Wed after the close) is the imminent demand read; a track, nothing scores:** the offshore proxy says Korea opens Wednesday with the threat still rejected — SKHY +1.75% (live, ~18:02Z), the US memory complex firm ahead of Nvidia. The Apple-CXMT catalyst is still UNPINNED (no dated primary since 12Z; the standing context cuts against it). The won holds flat-to-firm (1,383.05, 18:21Z) with externals verified flat (DXY 98.917 / CNH 6.7177). *US intraday, no settle (#70); base 6,742.74 the C1 base; US tape / memory / rates = Scout's canonical, direction only, stamped; SKHY my live pull; FX tuple same-clock 18:21Z (desk primary).*
  - evidence: **NOTHING SCORES — Korea SHUT since 06:30Z (KOSPI 6,742.74 / +0.68%, the as-of); US cash closes 20:00Z after our ~18:45Z cutoff → INTRADAY (#70). Q2 (rebound HELD?): YES — SK Hynix ADR (SKHY, Nasdaq) $158.09 / +1.75% (stockanalysis, Aug 25 ~18:02Z, live pull); US memory firm ahead of Nvidia (Scout's US read: Monday's −5–7% bought back, rebound holding); so Korea's offshore proxy is GREEN — opens Wed with the scare dead. Q1 (new primary?): NONE since 12Z — no Apple / Samsung / SK Hynix statement, filing, Commerce action, or fresh FT; catalyst UNPINNED. Standing context (reported, not new, cuts AGAINST): a Senate letter set an Aug 21 deadline for Apple to reject CXMT / YMTC; Micron lobbying the WH to DENY; CXMT ~2–3 generations behind (a ceiling on Apple's stack even if approved). Q3 (FX tuple, same-clock 18:21Z desk primary): DXY 98.917 (−0.09%) / CNH 6.7177 (−0.04%) / USD/KRW 1,383.05 (+0.01%) — externals genuinely FLAT at 18Z (not carried from 12Z), the won dead-flat vs 12:03Z 1,383.19; my Naver 17:59Z (1,383.60) and SKHY corroborate. The won flat-to-firm through a 2-day foreign exit, externals flat. Q4 (Korea dated overnight): NONE found — no KRX / FSS / Samsung / SK Hynix disclosure; next Korea event = Wed 06Z jong-ga. US TAPE (Scout, direction only): tech-led risk-on carrying Asia's V, front bid intraday (2Y ~4.21), dollar flat, Brent ~$89 — the hold-vs-climb SETTLE gate is 00Z-Wed. NVIDIA Wed Aug 26 after the US close (~$91B guide) → the demand read hits Korea THURSDAY.**
  - uncertainty: 🔵 — analytic track; nothing scores (Korea shut, no US settle). 🟢 that the offshore proxy held (SKHY +1.75%, live) and no new Apple-CXMT primary landed (catalyst UNPINNED) and the won is flat-firm on a verified same-clock 18:21Z tuple (DXY 98.917 / CNH 6.7177 / KRW 1,383.05, desk primary); the US tape is Scout's, direction only
  - follow: `NVIDIA Wed Aug 26 after the US close (~$91B guide) — the DEMAND read; it hits Korea THURSDAY, one clock after Wed's 06Z settle` `the APPLE-CXMT route — still UNPINNED; watch for a dated PRIMARY (an Apple filing, a Commerce action), not a re-publish` `WED 06Z SETTLE — does the broad recovery extend a 3rd session; C1 prev_close 6742.74` `the WON — flat-firm through a 2-day exit; a >±10-won same-clock session with DXY/CNH flat trips the switch` `Jackson Hole Aug 27–29 (Warsh Fri Aug 28); Sept 16 FOMC`

- **Falsifier / falsifier-v2 — NOT SCORED (US intraday track; Korea shut since 06:30Z, no US settle; #70):** semiconductor-switch stays **CONFIRMED / ON** (last scored 08-24, re-tests Wed's jong-ga). *Decouple-break — carried, UNADJUDICATED, and the DEMAND catalyst is now IMMINENT:* the memory scare is a threat-side input still UNPINNED; the DEMAND side gets its first real read at **NVIDIA Wed Aug 26 after the US close** (release ~4:20pm ET, ~$91B guide) — the AI/HBM demand pull for Korean memory, arriving before Micron (the desk has updated the demand gate to name it; see Q5). *Won-switch — NOT TRIPPED, flat-firm:* 1,383.05 (18:21Z same-clock tuple, DXY/CNH both flat) ≈ flat vs 12:03Z — the idiosyncratic firming holds through a 2-day foreign exit, but no >±10-won move, so no trip (only a single >±10-won same-clock session trips it). *Oil-channel — REFUTED for Korea (carried):* Brent ~$89 (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; one gate is CORRECTED:** the frame's demand gate named **Micron (late Sept) as the first real** demand catalyst. The finding: **NVIDIA Wed Aug 26** (after the US close) arrives EARLIER — a real HBM demand pull to Samsung / SK Hynix, hitting Korea Thursday — so it is the NEARER catalyst; the desk has updated the gate to name Nvidia (Micron remains the second, independent read). Otherwise no claim breaks: the won's idiosyncratic FIRMING is reinforced (flat-firm through a 2-day exit, externals verified flat), and the semi-switch is untested today.

- **Changed since last (12Z US pre-open → 18Z US intraday):** (1) the memory scare stayed DEAD offshore — SK Hynix ADR +1.75% (live), memory firm into Nvidia → Korea opens Wed with the threat rejected; (2) NO new Apple-CXMT primary — catalyst still UNPINNED; the standing context (Senate commit-deadline, Micron lobbying to deny, CXMT ~2–3 gen behind) cuts against the threat; (3) the won held flat-firm (1,383.05, verified 18:21Z tuple, DXY/CNH flat), dead-flat vs 12:03Z; (4) NVIDIA Wed Aug 26 after the close (release ~4:20pm ET) named the nearer demand read (hits Korea Thursday, ahead of Micron). Base carries 6,742.74; nothing scores; next settle Wednesday's 06Z.

**Watch:** `18Z US-INTRADAY TRACK — Korea SHUT since 06:30Z (carry 6,742.74 / plus 0.68pct, the as-of), US cash closes 20:00Z after our cutoff, so NOTHING scores (#70); base carries 6,742.74 (Weds 06Z declares prev_close 6742.74)` · `THE MEMORY SCARE STAYED DEAD OFFSHORE — SK Hynix ADR (SKHY) plus 1.75pct ($158.09, ~18:02Z live), US memory firm INTO Nvidia: Mondays rebound HELD and extended, Korea opens Wed with the threat rejected. NO new Apple-CXMT primary since 12Z - catalyst UNPINNED, stated plainly; standing context cuts AGAINST (Senate Aug 21 deadline to reject CXMT/YMTC, Micron lobbying to DENY, CXMT ~2-3 generations behind)` · `THE WON FLAT-to-FIRM through a 2-day foreign exit - verified same-clock 18:21Z tuple (won 1,383.05, DXY/CNH flat), dead-flat vs 12:03Z; idiosyncratic firming holds, no trip (only a greater-than-10-won same-clock session trips it). Q4: NO dated Korea item overnight (KRX/FSS/Samsung/SK Hynix); next Korea event = Wed 06Z jong-ga` · `NVIDIA WED AUG 26 AFTER THE US CLOSE (release ~4:20pm ET, call 5:00pm ET, ~91bn dollar guide) - the nearer DEMAND read for the decouple-break; because it lands after the US close it hits Korea THURSDAY, one clock AFTER Weds 06Z settle.
