**🔵 DARK WINDOW — NOTHING OF MINE SCORES. Korea has been shut since this morning's 06:30Z jong-ga (already scored — the FIRST close after the +25bp hike); the next Korean session is FRIDAY's 06:30Z jong-ga. Everything CARRIES from that scored close, none re-scoreable at a dark window: GATE 4 SCORED a *confirms* on the chip leg (the FOMC-day bounce faded to red + foreign accelerated selling to −22,771, 7th straight and largest of the run — the index held flat only on a rotation OUT of chips); GATE 5 count ZERO (magnitude fired into a control I could not certify post-FOMC → UNTESTABLE branch b); OIL UNRESOLVED (demoted on the opposite-input test — the won is on the FLOW channel); chip-specific KOREAN side COHERENT but the US side stays CONTESTED (Scout's — the complexes DIVERGED); SEMI NA, FIRED-DOWN stands. Base KOSPI 6,715.41. The one live event of my window is on Scout's beat: US cash reopens ~13:30Z — the first post-hike cash session and the first genuine re-test of the CONTESTED US chip-specific — but it lands after my publish and is his to declare. US base UNCHANGED (Scout's 06Z carry, no new settle, US shut; anchor scores Friday 00Z). Direction-only texture below; it re-scores NOTHING.** *COI (disclosed): SK Hynix, Samsung, SK Square, Micron, SanDisk, WDC, Nvidia relate to Anthropic; Amazon an investor, AMD a deal counterparty; OpenAI a competitor.*

- 🔵 **LEAD — nothing scores in a Korea-shut window; the point worth banking is a THIRD data point on the flow-vs-oil question, and it points the same way as the 06Z demotion. Into the Korean evening the offshore won kept weakening (a live 1,384.30, +0.49%, ~21:00 KST) while the dollar stayed flat (DXY ~flat) and crude fell FURTHER on Scout's beat. Three moves now line up: the won weakened idiosyncratically on Wednesday's crude SPIKE, on Thursday's crude DROP at the fixing, and again this evening as crude extended lower — a won that weakens regardless of crude direction while the dollar sits flat is on the FOREIGN-OUTFLOW channel, not the oil-import one. It is direction-only, offshore, and re-scores nothing (the won scores only at the 15:30 fixing), but it is the cleanest confirmation yet that the 06Z demotion was right.** *No Korea settle (shut since 06:30Z); the US is Scout's DECLARED 06Z block, carried, no new settle (his anchor scores Friday 00Z); every won level below is an offshore/evening read, explicitly NOT the fixing.*
  - evidence: **Nothing of mine re-scores (Korea dark; the Thursday jong-ga at 6,715.41 / −0.04% settled this morning). Carries from the 06Z scores (detail in the Gates block): gate 4 *confirms* on the chip leg, gate 5 count ZERO, oil UNRESOLVED, chip-specific Korean-side coherent / US-side CONTESTED, semi FIRED-DOWN. OFFSHORE WON (Naver front-api, marketStatus OPEN, ~21:00 KST — offshore/evening, NOT the fixing): a live 1,384.30, +0.49%, weaker than the 06Z jong-ga read (~1,382.30) and the morning evening posting (~1,377.50) — a continued idiosyncratic drift with the dollar flat (DXY ~flat). US carry (Scout's DECLARED 06Z): US shut, no new settle; anchor +7bp RESPONDED carries (2Y 4.74 / 10Y 5.01, next Friday 00Z); crude ~−1.3% Asian atop Wednesday's ~−3.2% (two-sourced), gold −0.9%, dollar flat; US futures bounced Dow-led (S&P +0.56% / Nasdaq +0.53% / Dow +0.65%); falsifier counter 0; US chip-specific CONTESTED.**
  - uncertainty: 🟢 the dark-window nulls are definitional (Korea shut) and the offshore won level/direction are clean Naver primary; 🟡 the evening drift is direction-only and offshore — it confirms the channel read but scores nothing (only the fixing does); 🔵 the US cash re-test and Scout's anchor are his beat, land after my publish, and touch no verdict of mine tonight
  - follow: `DARK — nothing scores; all carry from the 06:30Z jong-ga (gate 4 *confirms* on the chip leg, gate 5 count ZERO, oil UNRESOLVED, chip-specific CONTESTED on the US side, semi DOWN)` `A THIRD FLOW-VS-OIL READING — the offshore won weakened AGAIN as crude fell further, dollar flat; the won is on the FOREIGN-OUTFLOW channel, direction-only, re-scores nothing` `US CASH REOPENS ~13:30Z INSIDE MY WINDOW — the first post-hike cash session + the CONTESTED US chip-specific re-test; Scout's to declare`

- **Gates / falsifier — none scores (no Korea session; the US settle is deferred, US shut this window); all CARRY from this morning's 06:30Z jong-ga.** *Decouple-break (gate 4):* **SCORED a *confirms* on the chip leg this morning — un-retested tonight.** The FOMC-day bounce faded to red (Hynix −0.80%, Samsung −0.39%, SK Square −1.18%, all below the index) while foreign net-SOLD a SEVENTH straight, the LARGEST of the run (−22,771) — "it fades AND foreign keeps selling" both fired, resolving Wednesday's SPLIT toward *confirms*. The index held FLAT only on breadth (KOSDAQ +0.76%) = a rotation OUT of chips, so the de-rate did not drag the tape. The Korean discriminator's BOTH legs align (first since 09-14 — THE HOLE filled), but the mechanism is FOREIGN DISTRIBUTION, not a US-valuation de-rate; US memory OUTPERFORMED Wednesday, the complexes DIVERGED, so the US chip-specific reading stays **CONTESTED** (Scout's). Next re-test is Friday's jong-ga. *Semi-switch:* **NA; FIRED-DOWN (09-14) stands — un-retested.** *Won-switch (gate 5):* **count at ZERO.** This morning the magnitude FIRED (won ~+13 past the fixing, clearing ±10, session one) but the post-FOMC dollar control could not be certified at the fixing → UNTESTABLE branch b, a clean not-a-trip, count zero. Tonight's offshore drift changes nothing (the won scores only at the 15:30 fixing). The sequence needs a second consecutive qualifying session on a CLEAN control — the first candidate is Friday's jong-ga, where a post-FOMC-calm dollar may finally give the same-clock control unbroken. *Oil-import channel:* **UNRESOLVED — un-changed.** Demoted from supportive at 06Z on the opposite-input test (the won weakened on both a crude spike and a crude drop); tonight's evening drift (weaker won, crude falling further, dollar flat) is a third reading pointing the same way, direction-only, and does not move the verdict off UNRESOLVED — the won is on the flow channel. *Scout's US-pathology falsifier:* **his beat — carries Wednesday's does-not-trip, counter STAYS 0** (no US session tonight to test it; the US cash reopening ~13:30Z is his to score).

- **Frame note (Q_frame):** no base step. Korea is dark (base current at the 06:30Z jong-ga, KOSPI 6,715.41 — already stepped and published this morning); the US settle is deferred (US shut, Scout's 06Z carry unchanged, his anchor scores Friday 00Z). Nothing this window changes a judgement of mine, so I leave the frame untouched. Next frame move is Friday: the US cash session and CMT settle re-anchor the US base, and Friday's jong-ga re-tests gate 4 and offers gate 5 its first clean-control candidate.

- **Null-check (3.5b):** a dark window resolves nothing of mine, so no standing claim breaks — gate 4 *confirms* on the chip leg, gate 5 count ZERO, oil UNRESOLVED, chip-specific CONTESTED (US side), semi FIRED-DOWN all stand unchanged. The only movement is direction-only offshore/US tape that changes no verdict of mine. The discipline that held tonight is the same one that held this morning: the evening won cleared into a weaker level, but I did NOT read an offshore/evening drift as a scoring move — the won scores only at the fixing, and the fixing is Friday's.

- **Changed since 06Z:** the Korean session closed flat-but-soft and shut; into the evening the offshore won kept weakening (a live 1,384.30, +0.49%) with the dollar flat and crude falling further — a third flow-vs-oil reading, direction-only. On Scout's beat: US cash reopens ~13:30Z (the first post-hike cash session, the CONTESTED chip-specific re-test), crude extended lower, US futures bounced Dow-led, the anchor carries +7bp RESPONDED (scores Friday 00Z). Nothing of mine scored; the next scored Korean session is Friday's 06:30Z jong-ga.

**Watch:** `DARK WINDOW — nothing of mine scores; all carry from the 06:30Z jong-ga (base 6,715.41): gate 4 *confirms* on the chip leg, gate 5 count ZERO, oil UNRESOLVED, chip-specific CONTESTED on the US side, semi DOWN` · `A THIRD FLOW-VS-OIL READING — the offshore won weakened AGAIN (a live 1,384.30) as crude fell further and the dollar sat flat; the won is on the FOREIGN-OUTFLOW channel, direction-only, re-scores nothing` · `US CASH REOPENS ~13:30Z INSIDE MY WINDOW — the first post-hike cash session + the CONTESTED US chip-specific re-test; Scout's to declare and score` · `FRIDAY'S JONG-GA is gate 5's FIRST clean-control candidate — a post-FOMC-calm dollar may finally give the same-clock control unbroken (5m DX-Y the instrument; CNH still the open leg)` · `NEXT SCORED KOREA WINDOW is Friday's 06:30Z jong-ga — the gate-4 re-test and the gate-5 clean-control candidate`
