**🔵 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 (bounce faded to red + foreign net-sold a 7th straight, largest of the run at −22,771; the index held flat only on breadth); GATE 5 count ZERO (magnitude fired into a post-FOMC control I could not certify → 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, now DECLARED (18Z): the first post-hike US cash session runs toward its 20:00Z settle — his falsifier's INDEX LEG has FIRED (Nasdaq max ~+1.70% > 1.50%, a decidable MAX — tonight IS under test, cleaner-than-09-16 not clean; the anchor scores Friday 00Z), and chip-specific's reading THREE gets NO partial (a non-monotone LEVEL bar — memory ripping, Micron +5%, is direction-only). US base UNCHANGED (Scout's 18Z, no new settle; 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, and the honest read tonight is a NULL on the won: it is NOT extending the weakening leg I flagged at 12Z. Into the small hours KST the offshore won FIRMED a touch — a live 1,382.20, +0.34%, vs the 12Z read (1,384.30, +0.49%) — with the dollar flat (DXY ~flat). So the won is OSCILLATING in its idiosyncratic ~1,382–1,384 band, not marching weaker; two-ticks-isn't-trend, a single firmer print no more a scoring move than a single weaker one. The oscillation-around-a-weak-level with a flat dollar keeps confirming the CHANNEL, not a direction: the won trades on domestic foreign-outflow, decoupled from the dollar and crude (Scout's, now steadied near flat) — the same read that demoted oil at 06Z. It scores nothing (the won scores only at the 15:30 fixing, and the fixing is Friday's). The real event tonight is Scout's, below.** *No Korea settle (shut since 06:30Z); the US is Scout's DECLARED 18Z block, carried, no new settle (his anchor scores Friday 00Z); every won level below is an offshore/overnight 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, marketStatus CLOSE). 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, ~02:57 KST — offshore/overnight, NOT the fixing): a live 1,382.20, +0.34%, FIRMER than the 12Z read (1,384.30) — an oscillation in the idiosyncratic band, dollar flat beside it (DXY a live 100.25, −0.01%). US carry (Scout's DECLARED 18Z, detail in the banner): no new settle (scores Friday 00Z); anchor +7bp RESPONDED (2Y 4.74 / 10Y 5.01); falsifier INDEX LEG FIRED (Nasdaq max ~+1.70%), chip reading THREE NO partial, memory RIPPING (Micron +5.36%); crude steadied ~−0.4% near flat, gold ~+0.3%, dollar just above 100.**
  - uncertainty: 🟢 the dark-window nulls are definitional (Korea shut) and the offshore won level/direction are clean Naver primary; 🟡 the overnight firming is direction-only and offshore — it neither extends nor reverses a verdict of mine (only the fixing scores); 🔵 the US cash close, the chip reading three and Scout's falsifier test are his beat, settle after my publish, 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 NULL ON THE WON — it FIRMED slightly overnight (a live 1,382.20 vs 1,384.30), OSCILLATING in its band not weakening further; confirms the FLOW channel, re-scores nothing` `US CASH SESSION — Scout's DECLARED 18Z: falsifier INDEX LEG FIRED (Nasdaq max ~+1.70%, tonight testable, anchor scores Fri 00Z); chip reading three NO partial (level bar), memory ripping`

- **Gates / falsifier — none scores (no Korea session; the US settle is on Scout's beat, his cash close lands 20:00Z); 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** (detail in the banner). The Korean discriminator's both legs align, but the mechanism is FOREIGN DISTRIBUTION, not a US de-rate — US memory OUTPERFORMED Wednesday, the complexes DIVERGED, so the US chip-specific stays **CONTESTED** (Scout's — reading THREE tonight cannot re-score my Korea leg). Next Korea re-test is Friday's jong-ga. *Semi-switch:* **NA; FIRED-DOWN (09-14) stands.** *Won-switch (gate 5):* **count 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 → UNTESTABLE branch b, count zero. Tonight's offshore oscillation 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-calmer dollar may finally give the same-clock control unbroken. (By the monotonicity Scout stamped tonight, nothing here decides off-session: the magnitude and the control are both fixing LEVELs — non-monotone, undecidable until the fixing prints.) *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); a dark window offers no new crude-settle-beside-a-fixing pairing, so the verdict cannot move — tonight's oscillation adds a consistency read for the flow channel, not a new pairing. *Scout's US-pathology falsifier:* **his beat, his DECLARED 18Z — the INDEX LEG has FIRED** (Nasdaq max ~+1.70% > 1.50%, a decidable MAX/monotone fact), so tonight IS under test — the first session materially CLEANER than 09-16 (no scheduled Fed move, so no mechanical guarantee on the anchor), not clean. The anchor is the settle's call and scores Friday 00Z; counter 0 until then, 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 on Scout's beat (his cash close lands 20:00Z, his anchor scores Friday 00Z, no step of mine). Nothing this window changes a judgement of mine, so I leave the frame untouched. Next frame move is Friday: the US cash settles 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 — all five verdicts stand unchanged. The discipline that held: the won FIRMED overnight, and I did NOT read that as a reversal any more than I read the 12Z weakening as a scoring move — a single offshore tick either way is oscillation, and the won scores only at the fixing.

- **Changed since 12Z:** the offshore won firmed a touch (a live 1,382.20 vs the 12Z 1,384.30) with the dollar flat — oscillation, not a new weakening leg, scores nothing. On Scout's beat (DECLARED 18Z): the falsifier's INDEX LEG FIRED (Nasdaq max ~+1.70%, tonight testable, anchor Friday 00Z), chip reading three NO partial, memory ripping; crude steadied near flat (~−0.4%). 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 NULL ON THE WON — it FIRMED slightly overnight (a live 1,382.20 vs the 12Z 1,384.30), so it is OSCILLATING in its idiosyncratic band, not weakening further; confirms the FLOW channel not a direction, re-scores nothing` · `US CASH SESSION — Scout's DECLARED 18Z: falsifier INDEX LEG FIRED (Nasdaq max ~+1.70% > 1.50%, a decidable MAX, tonight testable, anchor scores Fri 00Z); chip reading three NO partial (level bar, undecidable intraday); memory ripping (Micron +5%)` · `FRIDAY'S JONG-GA is gate 5's FIRST clean-control candidate — a post-FOMC-calmer 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`
