🔵 DARK WINDOW — NOTHING OF MINE SCORES. Korea has been shut since this morning's 06:30Z Wednesday jong-ga (already scored — three gates settled there), and the next Korean session is Thursday's 06:30Z jong-ga. Everything on my side CARRIES, none re-scoreable at a dark window (detail in the Gates block): GATE 4 the four-session confirms run ENDED as a SPLIT; GATE 5 the count is back at ZERO (magnitude fails first = UNTESTABLE branch-b); OIL SUPPORTIVE on ONE reading; chip-specific HELD-not-established; semi-switch FIRED-DOWN. Base KOSPI 6,717.97. THE event of my window is Scout's: the Fed HIKED +25bp to 3.75–4.00% at 18:00Z (12-0 unanimous, hawkish; a dovish-hike tape — yields fell intraday, dollar flat), his declared decision — presser and settle deferred to Thursday 00Z. Direction-only to me, and it re-scores NOTHING of mine. US base UNCHANGED (Scout's Tuesday block; the decision-driven settle scores Thursday 00Z). The forward point, now IMMINENT (see the LEAD and gate-5 flag): Thursday's 06:30Z jong-ga — the FIRST to price the FOMC — fixes AFTER the decision, so the clean same-clock dollar control is GONE, and it SPLITS by gate. 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 as the Fed's hike lands on Scout's side; the point worth banking is the TESTABILITY one, now at the doorstep: the clean dollar control I had this morning does not repeat Thursday. My 06:30Z Wednesday fixing sat BEFORE both US events; Thursday's sits AFTER both, so any Thursday won move carries the FOMC's dollar inside it — gate 5 and the oil channel each lose their clean same-clock control, in DIFFERENT ways. No Korea settle (shut since 06:30Z); the US is Scout's DECLARED Tuesday block, carried, no new settle (the decision scores Thursday 00Z); the won read below is offshore/live, explicitly NOT the 15:30 fixing.

  • evidence: Nothing of mine re-scores (Korea dark; the Wednesday jong-ga at 6,717.97 / +1.37% settled this morning). Carries from the 06:30Z scores (detail in the Gates block): gate 4 a SPLIT, gate 5 count ZERO, oil SUPPORTIVE on one reading (+0.72pp residual), chip-specific HELD-not-established, semi-switch FIRED-DOWN. OFFSHORE WON (Naver front-api, marketStatus OPEN, ~03:00 KST Thursday AT the decision — offshore/live, NOT the fixing): a live 1,368.40, roughly flat vs the 12Z evening posting (~1,367.60) — drifting flat-to-slightly-weak into the decision, the read predates any FOMC reaction, direction-only, advances no count. US carry (Scout's DECLARED 18Z): the Fed HIKED +25bp to 3.75–4.00% (12-0 unanimous, hawkish) — the immediate tape read it a DOVISH hike (10Y yields fell a few bp intraday, dollar flat) but intraday does not score; the anchor stays Tuesday's +2bp INERT (2Y 4.67 / 10Y 5.00), scored Thursday 00Z (the HOT-but-ignored retail print is the second confound).
  • uncertainty: 🟢 the dark-window nulls are definitional (Korea shut, the US settle deferred to the decision) and the offshore won level/direction are clean (Naver primary); 🟡 the FOMC decision lands inside my window but is Scout's to declare, scores Thursday 00Z, and touches no verdict of mine tonight; 🔵 the decision re-anchors Thursday's Korean session, and the loss of the clean fixing-control there is the concrete cost I flag now
  • follow: DARK — nothing scores; all gates carry from the 06:30Z jong-ga (gate 4 SPLIT, gate 5 count ZERO, oil SUPPORTIVE one-reading, chip-specific held, semi DOWN) THURSDAY'S FIXING IS POST-FOMC — the clean same-clock dollar control is GONE for one session; gate 5 and oil lose it in DIFFERENT ways FOMC 18:00Z + retail 12:30Z = the doubly-confounded US session, Scout's, scores Thursday 00Z; retail printed HOT but the tape froze through it
  • sources: Naver — USD/KRW offshore ~1,368.40 (live, AT the decision, NOT the fixing) · Scout's DECLARED finance 09-16-18Z — the Fed hiked +25bp (12-0, hawkish; dovish-hike tape), scores Thursday 00Z, re-scores nothing

• Gates / falsifier — none scores (no Korea session; the US settle is deferred to the decision, scored Thursday 00Z); all CARRY from this morning's 06:30Z jong-ga. Decouple-break (gate 4): the four-session confirms* run ENDED — as a SPLIT, not a *reverses. The index bounced +1.37% (chip-led, held to the close), so the confirms branch's "it fades" is FALSE; but reverses needs "foreign net buys," and foreign net-SOLD a SIXTH straight (−16,825) while institutions (+12,104) drove it — price and foreign flow DECOUPLED, a domestic-institutional recovery, so neither branch fires. Not re-scored until Thursday's jong-ga. Chip-specific stays HELD-not-established (chip PRICE outperformance was the strongest UP reading yet, but foreign did not confirm and KOSDAQ +0.44% LAGGED = narrow). Semi-switch: FIRED-DOWN (09-14) stands — un-retested. Won-switch (gate 5): count at ZERO — the >±10 sequence EXPIRED unpartnered this morning (+9.2, a live 1,368.6, sub-±10; magnitude fails at session two before the control is even reached = UNTESTABLE branch b, not a does-not-trip). The INSTRUMENT is IDENTIFIED (the native FX wrap names the onshore 15:30 reference rate the test measures), but per settle discipline the won stays a labeled read (the FX endpoint is OPEN, not final; the settles allowlist points at the wrong series). ★ Forward — and it SPLITS by gate: my 06:30Z Wednesday fixing PRECEDED both US events (the cleanest dollar control available); Thursday's lands AFTER the now-landing 18:00Z decision. For GATE 5 that is the gate WORKING, not a loss — a dollar past the strict |Δ|<0.3% FAILS the control, so the session is UNTESTABLE (branch b), a clean not-a-trip that simply cannot be a scoring session two. For the OIL CHANNEL it is a PRECISION problem, not a control failure — the residual (won − dollar) survives the arithmetic but not its RELIABILITY: a small residual sitting on a large post-FOMC dollar is a difference between two big moves, far weaker than Wednesday's +0.72pp on a +0.06% dollar, so Thursday I report BOTH LEGS and label it precision-limited (same family as the resolution floor). WIDEN: NA. Oil-import channel: SUPPORTIVE stands — ONE reading (the first clean pairing since 08-21), not overturned; its next pairing is Thursday's post-FOMC fixing = precision-limited (see the gate-5 forward flag). Scout's US-pathology falsifier: his beat — anchor +2bp INERT a 2nd session, index counter 0; the doubly-confounded US session (retail 12:30Z + FOMC 18:00Z) scores Thursday 00Z, attribution unavailable.

• Frame note (Q_frame): no base step. Korea is dark (base current at the 06:30Z jong-ga, KOSPI 6,717.97); the US settle is deferred to Thursday 00Z (Scout's Tuesday block unchanged). Nothing this window changes a judgement of mine, so I leave the frame untouched. Next frame move is Thursday: the FOMC re-anchors the US base and Thursday's jong-ga re-tests gate 4, scored Thursday 00Z / 06Z.

• Null-check (3.5b): a dark window resolves nothing of mine, so no standing claim breaks — gate 4 SPLIT, gate 5 count ZERO, oil SUPPORTIVE (one reading), chip-specific held-not-established, semi FIRED-DOWN all stand unchanged. The only movement is direction-only US/offshore tape that changes no verdict of mine. Worth stating on a decision night: the hike itself cannot re-score any gate of mine — it is a statement of what the Fed BELIEVES, and my gates are written on prices, fixings and flows, not words (Scout reached the same point independently on his beat). It does not touch anything settled this morning; my verdicts next move at Thursday's jong-ga.

• Changed since 12Z: the pivotal US events arrived — retail sales printed HOT at 12:30Z (+1.2% MoM, ~4x consensus) but the tape FROZE THROUGH it, and the Fed HIKED +25bp to 3.75–4.00% at 18:00Z (12-0, hawkish; a dovish-hike tape — yields fell intraday), Scout's declared decision with the presser and settle deferred to Thursday 00Z. My beat, direction-only: the offshore won sits at a live 1,368.40 into the decision, roughly flat vs the 12Z evening posting. Nothing of mine scored; the next Korean session is Thursday's 06:30Z jong-ga.

Watch: DARK WINDOW — nothing of mine scores; all gates carry from the 06:30Z jong-ga (base 6,717.97) · THURSDAY'S FIXING IS POST-FOMC — SPLITS by gate: for GATE 5 the contaminated dollar is the gate WORKING (control fails → UNTESTABLE, a clean not-a-trip, not session two); for the OIL CHANNEL it is PRECISION (a small residual on a large dollar = a difference between big moves — report BOTH legs, label precision-limited) · FED HIKED +25bp to 3.75–4.00% (12-0, hawkish; a dovish-hike tape) — Scout's; presser + settle deferred to Thursday 00Z, doubly confounded with the HOT-but-ignored retail print; re-scores NOTHING of mine · WON going forward is the onshore 15:30 reference rate (identified this morning), a labeled read — not a declared settle; CNH is still the open control leg · NEXT SCORED KOREA WINDOW is Thursday 06Z — the first jong-ga to react to the FOMC (gate-4 re-test, and gate 5's count is back at zero)
