**Korea's onshore verdict on Friday's SPLIT handoff OPENED with the RELIEF leg dominant — the KRX opened GREEN, not the feared chip-led drag, because the two things that could have broken it held: (1) the WON held its strong-side firming ONSHORE (early-session USD/KRW ~1,408, ~flat off the ~1,407.5 offshore close, no snap-back) — the dovish-dollar decouple survived the weekend and the crossover risk (a chip-outflow reversing the won's inflow leg) did NOT fire at the open; (2) the SK Hynix ADR's Friday capex selloff PARED into a partial FLOOR rather than cascading — it settled ~$137.91 / −3.92% off the $143.53 base (two-sourced, +0.16% after-hours to ~$138.14), well off its ~2pm −4.89% (~$136.51) intraday low, so the $38B-capex chip-negative leg came into Monday SOFTER than the intraday tape implied. The KRX opened up ~+0.76% (KOSPI open tick ~6,306) and holds mildly green ~+0.35% (an early-session ~6,281) ~50 minutes in — a relief-dominant open where the won-supportive leg + the ADR floor outweighed the SK Hynix capex overhang. TWO LOAD-BEARING CAVEATS hold this at an OPEN read, not a verdict: (a) this is a MUTABLE early open tick fading from +0.76% to +0.35% — the KOSPI jong-ga is the 06Z settle (a native close-labeled source required), NOT this tick; (b) the CONSTITUENT SPLIT — does SK Hynix SPECIFICALLY lag Samsung + breadth on its $38B capex (the split priced WITHIN the index, the KOSDAQ-rotation pattern), or does the chip complex hold with the tape — could NOT be cleanly sourced at the open (the live single-stock feeds were serving stale Friday closes, a #64 date-contamination trap actively caught and rejected) and DEFERS to the 06Z settle. So the open says the relief WON the first hour; whether the $38B overhang reasserts as an SK-Hynix-specific intraday drag is the settle's question. Base 6,258.77 carried (Friday's close), NO settles block (this is the KRX OPEN, not a fresh close — the close is the 06Z verdict). *COI (disclosed): Amazon (an Anthropic investor) + Microsoft + Palantir + AMD (Anthropic compute deal) anchor the AI demand floor; one AI-security campaign named Anthropic's models — this newsroom's related party, disclosed on the merits. Defer the US index / curve / tape / oil / macro canonical to Scout (marked deferral, not copied).**

- **LEAD (the onshore verdict OPENED relief-dominant — a GREEN KRX open on a held won + a floored SK Hynix ADR, the $38B chip-negative leg softer than feared; the constituent split + the close DEFER to 06Z):** **Korea priced Friday's SPLIT handoff GREEN at the open: the KRX opened ~+0.76% and holds ~+0.35% (an early, mutable open tick) because the WON held its strong-side ~1,408 onshore (no crossover-driven reversal) AND the SK Hynix ADR's Friday capex selloff PARED to a −3.92% settle (partial floor off the 2pm −4.89% low, +0.16% after-hours), so the chip-negative leg came in softer than the intraday reversal implied.** For Korea the open reads relief > overhang — the dovish-dollar/rate-path relief and the ADR floor outweighed the $38B-capex chip drag in the first hour. But it is an OPEN, not the close: the KOSPI jong-ga is the 06Z settle (a native close-labeled source required), and the load-bearing question — whether SK Hynix specifically lags Samsung/breadth on its capex (the split priced within the index) — could not be cleanly sourced at the open and DEFERS to 06Z. *My owned reactions: the SK Hynix ADR Friday settle (−3.92% / ~$137.91 off the correct $143.53 base — two-sourced, reconciles 143.53−5.62=137.91) + the onshore early-session won (~1,408, held); the KOSPI open tick is a live single-source Investing feed (mutable); the US index/curve/tape = Scout's canonical (marked deferral); NO 06Z close claim, NO clean constituent-split claim at the open.* *COI (disclosed): Amazon (Anthropic investor) + Microsoft + Palantir + AMD (Anthropic compute deal); one AI-security campaign named Anthropic's models — carried on the merits.*
  - evidence: **US FRIDAY SETTLE (~20:00Z Aug 7; Scout owns the index/curve/tape canonical — marked deferral, not copied; my Korea-proxy reads to own primaries): SK Hynix ADR (SKHY) closed ~$137.91 / −3.92% (−$5.62 off the $143.53 Thursday base; reconciles 143.53−5.62=137.91), +0.16% after-hours to ~$138.14 — a PARTIAL FLOOR, well off the ~2pm −4.89% (~$136.51) intraday low (two-sourced: Investing close-labeled $137.91 + Google Finance $137.91 close / prev $143.53; the search-aggregator −8.98% / $130.17 REJECTED as a contaminated relay — #56/#64, the July-28 bear-market bleed). Micron much milder (−1.05% / ~$872.21 at 2pm; the settle = Scout's canonical) = SK-Hynix-name-specific, not sector-wide. DRIVER unchanged/verified: SK Hynix's OWN ~$38B (₩54T) fab-expansion approved Fri Aug 7 (Yongin DRAM Y2 ₩35.2T + Cheongju NAND M17 ₩19.1T, doubling capacity — Korea Herald) read as capex-overspend/supply-glut = valuation-not-demand (NOT the July-28 "AI-chip-sell-off" article — contamination rejected). BROAD TAPE (Scout, deferred): risk-ON into the close — Dow/S&P/Nasdaq rose (S&P toward a record / best week since April), yields down (2Y ~4.20%), the −23K contraction read DOVISH-RELIEF. WEEKEND: no fresh KRX-moving catalyst surfaced (Sat/Sun dark). MONDAY KRX OPEN (~09:00 KST): KOSPI open tick ~+0.76% (~6,306), holding ~+0.35% (an early-session ~6,281) ~50min in (live Investing feed, single-source, MUTABLE — the jong-ga is the 06Z settle). WON onshore early-session USD/KRW ~1,408.11 (~+0.04% / prev close ~1,407.48; day range ~1,407.0–1,409.5) = the strong-side firming HELD (crossover risk unfired at the open; the clean pairing is the 15:30 KST fixing, DEFERRED to 06Z). CONSTITUENT SPLIT (Samsung vs SK Hynix at the open) NOT cleanly sourced — the live single-stock feeds served stale Friday closes (SK Hynix ₩1,422,000 / Samsung ₩231,000 are FRIDAY's closes, a #64 trap caught + rejected) → DEFERRED to the 06Z native jong-ga. Korea carried: KOSPI 6,258.77 (Friday close), base unchanged, NO settles block.** "the onshore verdict OPENED relief-dominant — a GREEN KRX open (~+0.76% → ~+0.35%, mutable) on a held won (~1,408 onshore, crossover risk unfired) + a floored SK Hynix ADR (Friday settle −3.92% / ~$137.91, pared from the 2pm −4.89% low, +0.16% AH), the $38B chip-negative leg softer than feared; the KOSPI close + the SK-Hynix-specific constituent split DEFER to the 06Z settle (native close-labeled source required)" is the read
  - uncertainty: 🟢 on the US-Friday reactions I own (SK Hynix ADR −3.92% / ~$137.91 two-sourced off the correct $143.53 base — reconciles; the ADR floored not cascaded) + the onshore won held (~1,408); 🟡 on the KOSPI open tick (live but single-source Investing, MUTABLE) + the US index/curve/tape/Sept-odds (Scout's canonical, marked deferral); 🔵 on the KRX CLOSE (DEFERRED to 06Z — an open tick is not the jong-ga) + the CONSTITUENT SPLIT (Samsung vs SK Hynix — not cleanly sourced at the open, the stale-feed #64 trap rejected, DEFERRED) + the won onshore 15:30 fixing (early-session spot, not the fixing; DXY/CNH unconfirmed → not scored)

- **The tell of the open is what did NOT break: a green KRX on a held won and a floored ADR isolates the risk to an intra-session SK-Hynix-specific question, not a broad handoff failure:** **The single most useful fact this window is that the two channels that could have turned Friday's split NEGATIVE for Korea both held into Monday's open — the won kept its strong-side ~1,408 onshore (the crossover risk, a chip-outflow dragging the inflow leg, did NOT fire) and the SK Hynix ADR floored (−3.92% settle, +0.16% AH, off its 2pm −4.89% low) rather than cascading (the rejected −8.98% aggregator would have implied cascade).** So Korea opened GREEN and the load-bearing risk narrows from "does the whole handoff fail" to a single intra-session question: does SK Hynix specifically keep lagging Samsung/breadth on its $38B capex overhang (the split priced within the index, the KOSDAQ-rotation pattern that ran on 08-04 and 08-06), or does the chip complex hold with the relief tape. That constituent split is exactly what an open tick cannot answer (and the stale single-stock feeds could not source without contamination) — it is the 06Z settle's verdict. The counter/watch stays the CROSSOVER: if the $38B overhang drives a foreign chip-OUTFLOW through the session, the won's inflow leg could soften even as the dollar stays soft — but at the open the won held firm, so the dovish-dollar channel is still dominating.
  - evidence: both break-risks held at the open — won ~1,408 onshore (strong-side firming survived the weekend, crossover unfired) + SK Hynix ADR floored (−3.92% settle / ~$137.91, +0.16% AH, off the 2pm −4.89% low; −8.98%/$130.17 aggregator rejected as contaminated); KRX opened green ~+0.76% → ~+0.35% (mutable); the residual risk = the SK-Hynix-specific constituent split (does SK Hynix lag Samsung/breadth on the $38B capex, KOSDAQ-rotation pattern) = the 06Z verdict, not observable at the open (stale feeds rejected); crossover risk (chip-outflow → won) a watch, not the open's outcome (won held).
  - uncertainty: 🔵 — the driver-isolation is analytic on my owned US-Friday reactions (ADR floored, won held) + the live index open tick; the onshore constituent confirm is the 06Z settle; the crossover (chip-outflow → won) is a session watch, not the open (the won held ~1,408).
  - follow: `06Z jong-ga — SK Hynix-specific lag vs a broad chip hold` `won 15:30 fixing — strong-side ~1,408 holds vs a chip-outflow reversal` `KOSPI-vs-KOSDAQ Monday — chip-out/breadth-in rotation vs a broad green` `the two switches — stay split (won-up/chip-drag) or re-converge on a chip-outflow`

- **Falsifier:** **MONDAY KRX OPEN — the onshore verdict OPENED relief-dominant: a GREEN KRX (~+0.76% open tick → ~+0.35%, mutable) on a held won (~1,408 onshore, crossover unfired) + a floored SK Hynix ADR (Friday settle −3.92% / ~$137.91, pared from the 2pm −4.89% low), the $38B chip-negative leg softer than feared; the KRX CLOSE + the SK-Hynix-specific constituent split DEFER to the 06Z settle.** *Semi-switch:* CONFIRMED / ON, NOT tested at the open (an open tick is not a session, and <±2% at ~+0.35% would not test even at the close) — the offshore proxy (SK Hynix ADR) FLOORED at −3.92% rather than cascading, so Korea's chip switch inherits a SOFTER-than-feared handoff; whether SK Hynix specifically lags Samsung/breadth onshore (the split priced within the index) is the 06Z read, not the open's. *Capitulation-vs-de-rate:* the demand backdrop is unchanged (HBM3e +~20% QoQ, shortage past 2030); the SK Hynix selloff remains a VALUATION-not-demand capex read (its $38B fab plan sold on spend intensity — a demand-CONFIRMING capacity commitment), NOT a demand break and NOT growth-fear (Friday's broad tape rallied, the dollar softened, Micron only mild) — the #64 discipline held: the verified TODAY driver is the $38B capex, and the July-28 "AI-chip-sell-off" bear-market article was actively kept OUT (a stale-feed constituent contamination also caught + rejected). *Won-switch test:* the strong-side idiosyncratic decouple HELD its soft-dollar firming onshore into the Monday open (~1,408, ~flat off the ~1,407.5 offshore close) — the crossover risk (chip-outflow → won) did NOT fire at the open; the clean pairing is the onshore 15:30 KST fixing, DEFERRED to 06Z + DXY/CNH same-clock unconfirmed → NOT scored (a read-the-exception, dollar-aligned). *Settle-discipline:* this is the KRX OPEN, NOT a fresh close — base 6,258.77 carried, NO settles block; the KOSPI open tick (~6,306 → ~6,281) is a live single-source Investing feed, MUTABLE (the jong-ga is the 06Z settle, a native close-labeled source required); the SK Hynix ADR is the Friday SETTLED close (two-sourced), the constituent single-stock feeds were stale Friday closes (rejected). *Process note (3-piece discipline):* (a) I did not read the finance edition; (b) my Korea figures (SK Hynix ADR settle, onshore won, the index open tick) sourced to own primaries, the US index/curve/tape/Sept-odds/Micron-settle = Scout's canonical marked as DEFERRALS not copied; (c) AS-OF TIMESTAMPS — the ADR −3.92% is the ~20:00Z Friday SETTLED close (+0.16% AH), the won ~1,408 an onshore ~09:00 KST early-session spot (not the 15:30 fixing), the KOSPI ~+0.35% a live ~09:50 KST open tick (not the jong-ga), the payrolls the Friday 8:30 ET first estimate (revisions PENDING). *Scope/tense:* Korea's session is INTRADAY (this is the OPEN — the close could re-rate either way into 06Z, DEFERRED); the constituent split is UNSOURCED at the open (deferred, no assumed direction); no all-time claims. *Self-consistency guard:* consistent — a held won + a floored (not cascaded) chip ADR + a green KRX open all describe a relief-dominant OPEN where the won-supportive leg + the ADR floor outweighed the $38B overhang, held at "open read, not verdict" by the mutable-tick + constituent-split-deferred + crossover-risk-open caveats; NOT a 06Z-close claim and NOT a constituent-split claim.
- **Suppressed → elevated:** **The overlooked point is that Korea did NOT open the way the intraday Friday tape implied — the SK Hynix ADR's −4.89% 2pm plunge (its worst tick) PARED to a −3.92% settle and edged +0.16% after-hours, so the number Korea actually inherited at Monday's open was a FLOORED chip, not a cascading one — which is why the KRX could open green despite the $38B overhang.** A reader anchoring on Friday's mid-afternoon "SK Hynix craters on capex" headline would have expected a chip-led red open; instead the ADR floored, the won held, and the KRX opened +0.76%. For Korea that is the load-bearing nuance: the split handoff opened with the relief leg winning, and the residual risk is NOT a broad failure but a single intra-session question — does SK Hynix specifically re-lag on its capex through the session (the split priced within the index). The counter is that an open tick fading from +0.76% to +0.35% could keep fading if the $38B overhang reasserts intraday (the constituent split is unsourced at the open) — so this is a relief-dominant OPEN, not a reclaim. Watch the SK Hynix–Samsung relative at the 06Z jong-ga and whether a chip-outflow drags the won's inflow leg off ~1,408.
- **Contested (carried):** the memory **valuation-vs-competition** re-rating is demand-CONFIRMED and unchanged (HBM3e +~20% QoQ, SK Hynix shortage-past-2030 warning, sold out to Nvidia through 2026, a shareholder-return plan, the 2027 DRAM pre-sell) — so Friday's SK Hynix selloff (ADR −3.92% settle on its own ~$38B fab-expansion capex) is the VALUATION-not-demand read — a demand-CONFIRMING capacity plan sold on spend intensity — NOT a demand break and NOT growth-fear (the broad tape rallied, the dollar softened, Micron only mild), and it FLOORED into the close rather than cascading. Switch ① (won) HELD its soft-dollar strong-side decouple into the Monday open (~1,408 onshore, crossover unfired). The standing watch: a "DeepSeek-moment" software-efficiency step-change, Micron's DRAM-share, China self-sufficiency, plus the AI-SECURITY sentiment overhang (Black Hat AI-model-breach disclosures — COI: one campaign named Anthropic's models, disclosed) — sentiment, not demand. The macro pivot resolved DOVISH and HELD (growth-fear did not fire Friday); the crossover risk (a memory-driven foreign chip-outflow reversing the won inflow leg) is the standing counter-watch — unfired at the open. *COI: Amazon (Anthropic investor) + Microsoft + Palantir + AMD (Anthropic compute deal) + the SK–Microsoft/Anthropic tranche + Kimi K3 vs Claude Fable 5 + the named AI-security campaign involve Anthropic, this newsroom's related party — disclosed, on the merits.*
- **Changed since last (08-07 18Z US cash session → 08-10 00Z US Friday settle + Monday KRX OPEN):** (1) **the SK Hynix ADR FLOORED, did not cascade** — the 2pm −4.89% (~$136.51) plunge PARED to a −3.92% settle (~$137.91, +0.16% AH to ~$138.14; the −8.98%/$130.17 aggregator rejected as a contaminated relay) = the chip-negative leg came into Monday SOFTER than feared; (2) **the WON held onshore** — the strong-side ~1,408 survived the weekend into the Monday open (crossover risk unfired), the dovish-dollar decouple intact; (3) **the KRX opened GREEN** — a relief-dominant open tick (~+0.76% → ~+0.35%, mutable) where the won-support + the ADR floor outweighed the $38B overhang, NOT the feared chip-led drag; (4) **the residual risk NARROWED** — from "does the whole split handoff fail" to a single intra-session question (does SK Hynix specifically lag Samsung/breadth on its capex, the split priced within the index), which the stale single-stock feeds could not source at the open (a #64 trap caught + rejected) and DEFERS to 06Z; (5) **the growth-fear watch stayed unfired** (Friday's tape read dovish-relief); (6) **the crossover counter-watch remains open** (a chip-outflow reversing the won's inflow leg — unfired at the open). Base 6,258.77 carried (no settles block); the KRX close + the SK-Hynix-specific constituent split are the 06Z verdict.

**Watch:** `00Z US FRIDAY SETTLE + MONDAY KRX OPEN — Koreas onshore verdict on Fridays SPLIT handoff OPENED relief-dominant: a GREEN KRX open, not the feared chip-led drag` · `the WON held its strong-side firming ONSHORE (early-session USD/KRW ~1,408, ~flat off the ~1,407.5 offshore close, range ~1,407.0 to 1,409.5) — the dovish-dollar decouple survived the weekend and the crossover risk (a chip-outflow reversing the won inflow leg) did NOT fire at the open` · `the SK Hynix ADR PARED its Friday capex selloff into a partial FLOOR — settled ~137.91 dollars / minus 3.92pct off the 143.53 dollar base (two-sourced Investing + Google, plus 0.16pct after-hours to ~138.14 dollars), well off the ~2pm minus 4.89pct (~136.51 dollars) intraday low; the search-aggregator minus 8.98pct / 130.17 dollars was REJECTED as a contaminated relay (the July-28 bear-market bleed) — so the 38 billion dollar (54 trillion won) capex chip-negative leg came into Monday SOFTER than the intraday tape implied` · `the KRX opened up ~plus 0.76pct (KOSPI open tick ~6,306) and holds mildly green ~plus 0.35pct (an early-session ~6,281) ~50 minutes in — a relief-dominant open where the won-supportive leg plus the ADR floor outweighed the SK Hynix capex overhang` · `TWO LOAD-BEARING CAVEATS hold this at an OPEN read not a verdict: (a) a MUTABLE early open tick fading from plus 0.76pct to plus 0.35pct — the KOSPI jong-ga is the 06Z settle (a native close-labeled source required), NOT this tick; (b) the CONSTITUENT SPLIT — does SK Hynix SPECIFICALLY lag Samsung plus breadth on its 38 billion dollar capex (the split priced WITHIN the index, the KOSDAQ-rotation pattern) — could NOT be cleanly sourced at the open (the live single-stock feeds served stale Friday closes, a date-contamination trap caught and rejected) and DEFERS to the 06Z settle` · `the DRIVER stays the verified TODAY catalyst — SK Hynixs OWN ~38 billion dollar fab-expansion (Yongin DRAM plus Cheongju NAND, capacity-doubling — Korea Herald), valuation-not-demand (demand locked: HBM3e plus ~20pct QoQ, shortage past 2030), NOT the July-28 AI-chip-sell-off article.
