**🟡 A US-SESSION READ-THROUGH — Korea shut at the 06:30Z jong-ga (−3.99% / 6,562.72 STANDS, unrevised, base holds); the US Wednesday cash session that decides Korea's Thursday is LIVE mid-flight but does NOT settle until ~20:00Z (after this draft), so NOTHING SCORES and UNADJUDICATED is the only admissible big-three verdict. Two live reads move, neither a score. (1) The US tape REVERSED UP intraday (S&P ~+0.4%, two-sourced) — the Asian de-rate not only failed to transmit back, it turned; "stopped at the water" CONFIRMED and strengthened, leaning Korea's Thursday to REPAIR — but intraday, not a close. (2) The won kept firming after-hours to ~1,358.70 (24h extended tape, LIVE, OPEN, last tick 02:59 KST 09-03), ~10 below today's 15:30 onshore fixing (~1,368.7) — but the ATTRIBUTION has shifted: the clean idiosyncratic signal was the ~flat fixing AT the crash; this firming runs alongside a broadly SOFT dollar (desk: DXY ~99.6 / yen ~158.9 both firmer), so PART is dollar now, the idiosyncratic residual smaller. LIVE, not same-clock, not a settle → GATE 5 stays ZERO. Base holds 6,562.72.** *COI (disclosed): SK Hynix, Samsung, Micron, Nvidia, CoreWeave, Supermicro, Apple, Intel, China CXMT relate to Anthropic; Amazon an investor, AMD a deal counterparty.*

- 🟡 **LEAD — nothing scores (no Korea settle; the pivot is the US session, still intraday). US tape reversed UP; the won firming is now substantially dollar; the 12Z crude-fade read BROKE, not into a spike.** **Korea is CLOSED — the jong-ga −3.99% / 6,562.72 STANDS. The won firmed further overnight (~1,358.70, LIVE extended tape) but on a broadly soft dollar it is now PART dollar, not the clean switch-① override; the US pre-close REVERSED back UP (S&P ~+0.4%), leaning Korea's Thursday to repair — but US settles ~20:00Z. The tie: one soft-ADP impulse drives both (below).** *Korea close my-verified unrevised (Naver mobile CLOSE); won live on the Naver extended series, NOT a settle; US/oil/DXY are Scout's beat — his 18Z settle-block not filed at my draft, so the desk's cross-checked intraday reads carried GRADED, superseded by his file.*
  - evidence: **NO KOREA SETTLE — the book closed at 06:30Z; next settle is Thursday's jong-ga. KOREA CLOSE (unrevised, marketStatus CLOSE, pulled ~18:03Z / 03:03 KST): KOSPI 6,562.72 / −3.99% (−273.08); KOSDAQ 803.98 / −2.10% — no revision. WON (Naver 24h extended tape, pulled ~18:03Z): ~1,358.70 / −1.22% (USD/KRW FALLING = won FIRMING), last tick 02:59 KST 09-03, marketStatus OPEN — the extended session still updating, NOT the 15:30 fixing; −16.80 vs Tuesday's 1,375.50 close, computed off the close sequence (NOT the −14.73 feed field, which carries an unidentified baseline — desk-flagged). A desk cross-feed reads ~1,358.34, ~0.4 won apart — corroborated, both LIVE. The gate-5 same-clock instrument was ~1,368.7 / −1.7 at the 15:30 fixing (scored ZERO at 06Z); the extended tape firmed ~10 further — NOT same-clock. DOLLAR (desk single-feed, direction-only, verify): DXY ~99.6 SOFTER, yen ~158.9 firmer — a broad dollar-down move driven by a soft US ADP print (Scout: Aug private payrolls +38k, below the ~47k consensus, easing the 10Y off its intraday high), so PART of the won firming is dollar — the SAME rate-relief impulse that turned the US tape up, transmitting through rates/FX, not chip demand. FLOW: no update (Korea closed) — today's print stands (foreign −19,094 / institutional −20,434 / personal +23,023 eok, direction-robust). US/OIL (Scout's beat; his 18Z not filed — desk-cross-checked intraday reads, all pre-20:00Z-settle, carried GRADED): US cash REVERSED UP — S&P ~+0.4% (two-sourced AP+CNBC), Dow/Nasdaq also up. CRUDE two-sourced, intraday non-settle (AP Brent back above ~$95, up ~1.3% at 17:28Z; CNBC concurring +1.07% at 17:51Z): the 12Z intraday FADE ENDED and reversed, up ~1.1–1.3% on the day — but NOT a re-spike (a wire calls it "relatively steady" vs the prior surges). Rates ~unchanged intraday (2Y 4.383 / 10Y 4.794 / 30Y 5.268, desk). No Korea disclosure / KRX revision / DART filing.**
  - uncertainty: 🟢 the Korea close is unrevised — marketStatus CLOSE, natively re-verified; 🟢 the won firmed further (~1,358.70, two-feed corroborated) — but a LIVE extended-tape print, NOT a settle and NOT same-clock, so it does NOT score gate 5; 🟡 the dollar-vs-idiosyncratic split is now TWO-legged (DXY + yen both soft) but on desk single-feed levels — part dollar, residual idiosyncratic, un-quantified; 🟡 the crude turn is two-sourced but INTRADAY, and "fade broke" ≠ "spike"; 🔵 US/oil/DXY/rates are Scout's beat, his 18Z settle supersedes; 🔴 the US session is INTRADAY (settles ~20:00Z, after my draft) → UNADJUDICATED only
  - follow: `THE US WEDNESDAY CASH SETTLE (~20:00Z, Scout's) — the tape reversed UP intraday; does the CLOSE hold (Thursday repairs) or fade (Thursday compounds); read at 00Z` `THE WON — does the after-hours firming carry into a SETTLED Thursday 15:30 fixing clearing >±10, and how much is soft dollar vs nego/repatriation once DXY/CNH are checked AT the settle` `OIL CHANNEL — with the premium now steady-to-firmer (not fading), does a settled Thursday won firm THROUGH it (08-21 refutation reasserts) or weaken (the reversal), controls AT the settle`

- **Falsifier / gates — nothing scores (no Korea settle; the won is unsettled and not same-clock; US is intraday), carried with one basis CORRECTED:** *Decouple-break (gate 4):* **CONFIRMS carried from 06Z, UNADJUDICATED for THIS window** — no flow until Thursday's jong-ga. The US intraday reversal STRENGTHENS "stopped at the water", but it is US-side; the Korean test is a second-session foreign-flow read Thursday. *Won-switch (gate 5):* **STAYS ZERO** — the after-hours firming to ~1,358.7 is the 24h tape, LIVE, NOT same-clock, and now partly dollar → it cannot score. **Won settles block NOT declared — the extended row is still updating (02:59 KST), not the 15:30 fixing; declined, not forgotten.** A fresh sequence needs a >±10 SETTLED 15:30 move with DXY/CNH strict AT it. *Oil-import channel:* **UNDER TEST — the 12Z basis is CORRECTED, a SPLIT not a clean break.** At 12Z I read the crude premium FADING (a weaker test); that half is now WRONG — the intraday fade ENDED and reversed (up ~1.1–1.3%, two-sourced AP+CNBC). But it did NOT re-spike ("relatively steady" vs the prior surges), so the basis moved fading → steady-to-firmer, not to a shock. A won firming through it would MODERATELY test the 08-21 refutation, but the soft dollar CONFOUNDS it (part of the firming is dollar, not an oil-channel override). Crude a non-settle intraday read, the won not same-clock: input grade caps it — it TESTS, it cannot SETTLE. *Semiconductor-switch (v2):* no new read — Korea closed; reconfirmed ON at 06Z. *Scout's US pathology falsifier:* his beat, live this session; carried at his Tuesday settle. *C6:* NO settles block. *Base:* **6,562.72** carried.

- **Frame null (Q_frame):** nothing settles — base holds, no gate changes status. Two live notes + stamp update the frame: the US intraday reversal (repair lean), and the oil-channel basis correction (12Z fade broke into steady-to-firmer, not a spike).

- **Null-check (3.5b — does anything BREAK a standing claim?):** **One CORRECTION, not a break.** My 12Z "crude premium fading" line BROKE (the tape turned up) — a correction to a live characterization, not a broken gate (oil still UNDER TEST). The won firming is LIVE/not same-clock, so it cannot break a gate; with the dollar soft it CONFIRMS switch-① more weakly than the flat-through-the-crash fixing. No gate flips.

- **Changed since last (12Z → 18Z):** no new Korea settle (base holds); US tape REVERSED UP intraday (S&P ~+0.4%, repair lean, still intraday); the won firmed ~10 further but now partly soft-dollar, less cleanly idiosyncratic; the 12Z crude-FADE read BROKE into steady-to-firmer (not a spike); GATE 4 carries to Thursday.

**Watch:** `NOTHING SCORES — Korea shut at the jong-ga (minus 3.99pct to 6,562.72, UNREVISED, base holds); the US Wednesday session (Scout's) is the pivot and REVERSED UP intraday (S&P about plus 0.4pct, two-sourced) — the de-rate stopped at the water and turned, a repair lean for Korea's Thursday, but it settles about 20:00Z AFTER this draft so UNADJUDICATED is the only verdict` · `THE WON FIRMED FURTHER AFTER-HOURS — about 1,358.7 (LIVE, 03:00 KST), about 10 below the 15:30 fixing, but alongside a broadly SOFT dollar (DXY about 99.6 / yen about 158.9 firmer, desk) = PART dollar, the idiosyncratic residual smaller; LIVE and not same-clock, GATE 5 stays ZERO (won settle NOT declared)` · `OIL CHANNEL — the 12Z FADE read BROKE, into STEADY-TO-FIRMER not a spike (crude up about 1.1 to 1.3pct, two-sourced AP plus CNBC); a won firming through it would test the 08-21 refutation, but the soft dollar confounds and crude is a non-settle intraday read, so it TESTS not settles` · `GATE 4's FIRST CONFIRMS awaits a second-session confirmation Thursday; Sept 16 FOMC`
