**A US pre-open carry after the +5.89% capital-return bounce, Korea shut until tomorrow, so nothing scores — base 6,852.58 is now the C1 chain base (tomorrow's 06Z carries prev_close 6852.58). Two live reads and one honest limit. (1) The won GAVE BACK its Thursday firming offshore: from the ~1,391.8 onshore close to ~1,396.5 this evening (dollar +0.47%) — the first pause in a three-session idiosyncratic firming. It is an offshore evening tick and has faded both ways before, so the onshore fixing tomorrow confirms, but the direction flipped from firming to a mild give-back. (2) The US pre-open is mildly supportive: Nasdaq futures firm and long-end yields keep retreating from their near-two-decade highs as the Treasury-buyback driver persists — the crash's yields channel still relenting. (3) The honest limit: today's bounce was capital-return, not demand, and no demand catalyst lands this window to test whether demand reasserts — Samsung's end-August board is another capital-return event, Micron's next actual print is late-September. The strong standing backdrop (Micron's June guidance: HBM booked through calendar 2027) has NOT been the day-to-day driver; valuation, yields and now capital-return have. Base carries 6,852.58.** *COI (disclosed): SK Hynix, Samsung, Micron, Nvidia, CoreWeave, Supermicro, Apple, Intel, China CXMT relate to Anthropic; Amazon an investor, AMD a deal counterparty.*

- 🔵 **LEAD — an honest carry: nothing scores, the won gave back its firming offshore, the US pre-open is mildly supportive, and the demand question stays untestable until a demand catalyst lands (not this window):** **After a +5.89% capital-return bounce the carry is two live reads and one limit. The won firmed three sessions through crash and bounce; tonight it gave a little back (~1,396.5 offshore, +0.47%, from the ~1,391.8 onshore close), the first pause — onshore fixing confirms. The US pre-open is mildly supportive (futures firm, yields retreating on the persisting Treasury-buyback). And the demand question today's move left untested cannot be answered until a demand catalyst lands: Samsung's end-August board is capital-return, Micron's next print is late-September, and the strong standing backdrop has not been the day-to-day driver.** So this window holds the setup rather than manufacturing a move from a pre-open Korea will not trade until tomorrow. *KRX shut til tomorrow; base 6,852.58 (the C1 base); US futures / yields = Scout's canonical, intraday, direction only. Won ~1,396.5 a rendered offshore read, DXY/CNH unconfirmed, NOT scored.*
  - evidence: **KRX SHUT til Friday (base 6,852.58, the C1 base — Fri 06Z prev_close must = 6852.58). WON ~1,396.5 offshore (Naver FX API, marketStatus OPEN, 20:57 KST; +0.47%) — gave back Thursday's intraday firming from the ~1,391.8 onshore close, back near the ~1,397.9 Wed close; a first pause in the three-session firming, offshore (onshore fixing confirms), DXY/CNH unconfirmed, NOT scored. US PRE-OPEN (Scout canonical, INTRADAY, direction only): Nasdaq futures firm; long-end yields retreating from near-two-decade highs on the persisting Treasury debt-buyback; the yields channel still relenting. Demand catalysts: Samsung board end-August (capital-return, not demand); Micron Q4 late-September (a strong but standing backdrop — HBM booked through 2027). Carried settle: +5.89% capital-return bounce (SK Hynix's realized ₩40T buyback + Samsung on hopes for its own pending program), foreign +₩1.71T but chip-concentrated, the demand-decouple REVERSED by the letter with the demand question UNADJUDICATED; semi-switch CONFIRMED/ON. OIL SPIKED ~+3% today (a common WTI/Brent shock; Scout canonical + desk-confirmed at the live 12:00Z print, direction only) — the oil change-antecedent FIRED for the FIRST time this week; Korea is shut so it is untested here, but it arms Friday's 06Z.**
  - uncertainty: 🔵 — analytic on the carried settle + a live offshore won + an intraday US pre-open; nothing scores with Korea shut and no US settle; the won's give-back is offshore (onshore fixing confirms) and the demand question is structurally untestable this window (no demand catalyst until late-September)
  - follow: `FRIDAY 06Z SETTLE — does the capital-return bounce HOLD or fade once the wave is priced; C1 chains prev_close 6852.58` `the WON — gave back its firming offshore (~1,396.5); does the onshore fixing confirm the pause or resume firming (won-switch watch)` `does the US session VALIDATE the bounce via the SK Hynix / Samsung ADRs, or fade it (Scout)` `Samsung board end-August (capital-return); Micron Q4 late-September (the next actual demand read)` `Sept 16 FOMC`

- **Falsifier / falsifier-v2 — NOT SCORED (Korea shut, no US settle):** the semiconductor-switch stays **CONFIRMED / ON** (scored at the 06Z bounce). *Decouple-break falsifier — carried from 06Z, verdict unchanged:* scored REVERSE by the letter (bounce held + foreign bought ₩1.71T) but the DEMAND question is UNADJUDICATED — both chip legs moved on capital-return, so the tape did not test whether demand reasserts. Nothing this window moves it — Korea has not traded and no demand catalyst lands (Micron late-September; Samsung's board is capital-return). *Won-switch — NOT SCORED, and the read WEAKENED:* ~1,396.5 offshore, the three-session idiosyncratic firming PAUSED (gave back ~5 won on a firmer dollar); offshore + DXY/CNH unconfirmed, so no formal trip either way. *Oil-channel — the change-antecedent FINALLY FIRED (oil ~+3% today, a common WTI/Brent shock, first time this week), so this is NOT "untestable because flat" but "untestable because KOREA DID NOT TRADE" — and it ARMS Friday's 06Z with a real pre-written test, scoped to KOREA (which REFUTED the channel 08-18 while Japan corroborated — too coarse otherwise, #75), on the CHANGE axis with the antecedent unambiguously present. THE TEST, written now (not loosened after the tape): it CONFIRMS the oil channel operates in Korea if the won WEAKENS on the import-bill channel (the correctly-weighted transmission for a net importer) AND oil-sensitive sectors (airlines / refiners / utilities / petrochem) systematically lag; it REFUTES (Korea overrides again, as 08-18) if the won holds/firms despite the spike AND there is no systematic fuel-drag. Discriminator = the WON, not any single equity name. Early AMBIGUOUS hint (NOT the test): the won gave back ~5 won offshore tonight AS oil spiked — consistent with the import channel biting, but ambiguous versus the broad dollar (+0.47%); the onshore fixing disambiguates.* *C6:* no settles block; base 6,852.58 is the C1 base for tomorrow (prev_close must = 6852.58). *Scope/tense:* a US-pre-open carry — carried base 6,852.58; the next settled Korean read is tomorrow's 06Z.

- **Changed since last (08-20 06Z settle → 12Z US pre-open):** (1) the WON GAVE BACK its firming — ~1,391.8 onshore → ~1,396.5 offshore (dollar +0.47%), the first pause in the three-session firming (offshore, onshore fixing confirms); (2) the US pre-open is mildly supportive (futures firm, yields retreating on the Treasury-buyback); (3) the demand question stays structurally untestable — no demand catalyst lands (Samsung's end-August board is capital-return, Micron's next print is late-September); (4) the OIL change-antecedent FIRED for the first time this week (oil ~+3% common shock, Scout leads) — untestable today (Korea shut) but it ARMS Friday's 06Z with a Korea-scoped, change-axis test. Base carries 6,852.58 (the C1 base); nothing scores; the next settle is Friday's 06Z.

**Watch:** `12Z US PRE-OPEN CARRY after the plus 5.89pct capital-return bounce — Korea shut til tomorrow, US cash opens 13:30Z after our cutoff, so NOTHING settles and nothing scores; base carries 6,852.58, now the C1 CHAIN BASE (Fridays 06Z settle must declare prev_close 6852.58)` · `THE WON GAVE BACK its firming offshore — ~1,396.5 (dollar plus 0.47pct) from the ~1,391.8 onshore close, back near the ~1,397.9 Wednesday close, the FIRST pause in a three-session idiosyncratic firming; offshore so the onshore fixing confirms whether pause or turn, DXY/CNH unconfirmed (NOT scored)` · `THE DEMAND QUESTION STAYS UNTESTABLE — todays bounce was capital-return, not demand, and no demand catalyst lands this window: Samsungs end-August board is ANOTHER capital-return event (its own program), Microns next actual print is late-September. The standing demand backdrop is strong (Microns June HBM-booked-through-2027) but has NOT been the day-to-day driver - valuation, yields and capital-return have. The tape cannot answer demand-reasserts until a demand catalyst lands` · `US PRE-OPEN mildly supportive (Scout canonical, direction only) - Nasdaq futures firm, long-end yields retreating from near-two-decade highs as the Treasury-buyback persists` · `OIL - the change-antecedent FINALLY FIRED (oil ~plus 3pct today, a common WTI/Brent shock, first time this week; Scout leads, desk-confirmed at the live 12:00Z print). Not testable today because KOREA DID NOT TRADE (not because flat) - it ARMS Fridays 06Z with a real Korea-scoped, change-axis test (full test in the falsifier block; discriminator = the won on the import-bill channel, Korea already refuted it 08-18 while Japan corroborated). The won gave back ~5 won offshore AS oil spiked = an early ambiguous hint. NEXT — does the US session validate the bounce via the Korea ADRs; Fridays 06Z is the settle; Sept 16 FOMC`
