**🟡 THE SCORE THIS WINDOW: the Tuesday jong-ga settled and gate 4 (decouple-break) SCORES *confirms* a FOURTH consecutive on the index/flow metric — KOSPI FADED (−0.85%, no bounce) and foreign net-SOLD a FIFTH straight session — but it is WEAK and self-correcting on two counts: (1) it DECELERATED hard (foreign roughly halved, the index a quarter of Monday's move), and (2) the *confirms*'s OWN mechanism clause — "the chip complex keeps tracking a US valuation de-rate" — IS FALSE today. The chips OUTPERFORMED the index (all three better than −0.85%) even as US memory fell ~−4.92% overnight, so the KOSPI's drop was NON-CHIP (broad large-cap foreign outflow, FOMC-eve; small-caps rotated up, KOSDAQ green). This EXPOSES A HOLE in my own chip-specific discriminator (below): the KOSDAQ-flow signature is IDENTICAL to Monday's, but Monday had chip PRICE leadership to disambiguate and today has none — so flow-breadth ALONE never identified the mechanism. The chip-specific MECHANISM (held-not-established at 00Z) is NOT upgraded. Semi-switch NA (never armed). Won +10.90 (first >±10 of the run); gate 5 UNTESTABLE session-one but LIVE (DXY leg inside the flat bar, control incomplete). Base steps 6,684.37 → 6,627.26.** *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 — gate 4 SCORES *confirms* a FOURTH on the index/flow metric, but the finding that matters CUTS AGAINST the chip-specific reading I have carried: the chips OUTPERFORMED a falling index while US memory dropped ~5% overnight, so today's KOSPI fade was NOT chip-led, and my flow-only discriminator is shown to be under-identified.** *Korea's base steps to the settled Tuesday jong-ga; the US is Scout's DECLARED Monday block (unchanged — his next settle is tonight, after my window); the won is the onshore fixing, same-clock, reported without a verified attribution.*
  - evidence: **JONG-GA (Naver mobile API, marketStatus CLOSE, 15:35 KST; two-sourced by a native close wrap): KOSPI 6,627.26 / −0.85% (−57.11 off 6,684.37) — FADED, no bounce; KOSDAQ 812.41 / +0.70% — GREEN (a large-cap-down / small-cap-up SPLIT). CHIPS OUTPERFORMED the index: SK Hynix ₩1,690,000 / −0.41%, Samsung ₩248,500 / −0.20%, SK Square ₩1,000,000 / 0.00% — all BETTER than −0.85% and roughly FLAT despite US memory settling ~−4.92% overnight (Scout's block). FLOW (Naver /trend, SIGN-reliable, magnitude soft): KOSPI foreign −15,711 / institutions −9,044 / retail +8,324; KOSDAQ foreign +238 / institutions +1,107 / retail −1,398 — foreign OPPOSITE signs across the boards, BOUGHT the small-cap board. Native wraps corroborate a FIFTH consecutive foreign selling session. WON (onshore fixing, same-clock 15:35): 1,359.40, +10.90 weaker vs Monday's 1,348.50 (+0.81%) — the first >±10 of the run.**
  - uncertainty: 🟢 the settle, split, chip-outperformance and flow signs are hard (Naver primary + native close wrap); 🟡 the MECHANISM behind the KOSPI fade is UNDER-IDENTIFIED — the flow signature fits both a chip-specific de-rate and a broad large-cap risk-off, and today's price leg (chips outperform) points AWAY from chip-specific; 🔵 the won cleared ±10 (first of the run); the DXY leg is inside the strict flat bar (Scout's +0.28%, by 0.02pp) but the control is INCOMPLETE (not at the fixing, CNH unverified) — not failed, not established
  - follow: `THE DISCRIMINATOR HAS A HOLE — foreign-flow concentration in KOSPI fits BOTH chip-specific AND large-cap-broad; it identified the mechanism on Monday ONLY because chips also LED the price move, and today the same flow appears with chips OUTPERFORMING` `CHIPS DECOUPLED UP FROM US MEMORY — memory −4.92% overnight, Korean chips ~flat: the demand leg held for chips` `MECHANISM NOT UPGRADED — a repeat flow signature WITHOUT the price leg is weaker than a clean repeat; held-not-established stands` `WEDNESDAY FOMC is the disambiguator (Scout's beat)`

- **GATE 4 (decouple-break) — SCORED *confirms* a FOURTH on the index/flow metric; the mechanism clause is FALSIFIED.** Literal read → *confirms* (faded −0.85%, foreign a fifth straight sell). **But score the metric, report the composite:** the *confirms* branch is defined as "the chip complex keeps TRACKING a US valuation de-rate," and that clause is FALSE today — the US de-rate did NOT transmit to Korean chip prices (chips OUTPERFORMED). What faded the index was broad large-cap foreign selling (non-chip), not the chip complex tracking the US down; and the run DECELERATED hard. Net: *confirms* holds as an index/flow fact; the chip-tracking mechanism it was meant to capture did the OPPOSITE.

- **THE FINDING THAT MATTERS — my chip-specific discriminator was under-identified, and I would rather say it than let the flow branch carry the window.** The Monday call rested on a KOSDAQ-flow discriminator: foreign sold KOSPI hard but spared the KOSDAQ, which a broad risk-off (hitting both boards) would not do. Today reproduces that signature EXACTLY (KOSPI foreign −15,711 vs KOSDAQ +238 — spared AND bought), yet the chips did NOT weaken at all. That is the tell: **"concentrated in KOSPI" is a LARGE-CAP-vs-SMALL-CAP split as much as a CHIP-vs-NON-CHIP split, and both predict the identical flow signature.** Monday separated them ONLY because chips also LED the price move (−4% to −8% vs a −3.26% index); strip the price leg, as today does, and flow breadth alone cannot tell a chip de-rate from a broad large-cap outflow. The mechanism therefore does NOT upgrade: a matching signature WITHOUT the price leadership is WEAKER than a clean repeat — I pre-committed at 00Z that even a clean repeat leaves it held-not-established. *(The desk originated this; I reached it from my own verified tape before adopting.)*

- **Falsifier / other gates:** *Semi-switch:* **NA — did not arm.** −0.85% is nowhere near ±2% ("did not test," not a near-miss); the FIRED-DOWN 09-14 status stands. *Won-switch (gate 5):* **UNTESTABLE — session ONE; but a LIVE sequence, NOT a dead branch.** The onshore fixing moved +10.90 won (1,348.50 → 1,359.40), the FIRST >±10 of the run — Monday was sub-±10, so no consecutive partner (branch b). On the control: the DXY leg is INSIDE the strict flat bar — Scout's DECLARED dollar is **+0.28% off Monday's settle** (the matching Monday→Tuesday window; NOT his +0.32% Friday→Monday figure), clearing the <0.30% line by just 0.02pp — so the dollar does NOT disqualify the won. But neither reading is AT the 15:30 fixing and CNH is unverified, so the control is INCOMPLETE — not established, not failed. A SECOND consecutive >±10 fixing tomorrow with controls re-established AT it would be the run's FIRST trip since 08-31. *WIDEN:* **NA — a down session.** *Oil-import channel:* **UNTESTED STANDS — not refuted** (no crude settle this window = no clean crude+won-at-a-settle pairing). Symmetry note (mirror of 09-14's dollar-only null): the won weakened ~0.53pp BEYOND the dollar (+0.81% vs +0.28%) — the FIRST idiosyncratic move in the channel's PREDICTED direction (crude firm, won weaker) this run. But an OBSERVATION, not a test — different clocks, no crude settle to pair; do NOT upgrade to evidence (refuted since 08-21). *Scout's US-pathology falsifier:* **his beat — unchanged from his declared Monday block (index leg did not fire, UNTESTABLE, counter 0); his next settle is tonight, after my window.**

- **Frame note (Q_frame):** base STEPS 6,684.37 → 6,627.26; gate 4 *confirms* a FOURTH. The load-bearing action: I DOWNGRADE confidence in the chip-specific mechanism note — not to refuted, but flagging the KOSDAQ-flow discriminator as UNDER-IDENTIFIED (necessary, not sufficient; needs the co-moving price leg). Verdict stays HELD-NOT-ESTABLISHED (lower confidence in the supporting evidence). No US base step (Scout's block unchanged); stamp bumped same commit.

- **Null-check (3.5b):** the item that RESOLVED is gate 4 (above). No standing claim of mine BREAKS: semi-switch DOWN stands (un-retested), gate 5 stays NOT PINNED / UNTESTABLE, the oil channel stays UNTESTED. What changed is a confidence downgrade on the discriminator, not a broken claim.

- **Changed since 00Z:** the direction-only open split HELD and SHARPENED at the settle — chips OUTPERFORMED, foreign bought the KOSDAQ outright, the index faded on non-chip outflow. The decisive new fact is the discriminator hole (above); foreign extended to a fifth session but ~halved; the won cleared ±10 for the first time. FOMC decision Wednesday (Scout's beat).

**Watch:** `GATE 4 *confirms* a 4th on index/flow — but DECELERATING, and its mechanism clause (chips track the US de-rate) is FALSE today: chips OUTPERFORMED` · `THE DISCRIMINATOR HAS A HOLE — foreign-flow concentration ≠ chip-specific without the price leg; the two came apart today` · `CHIPS DECOUPLED UP from a −4.92% US memory night — the demand leg held for chips` · `WON CLEARED ±10 (+10.90), first of the run — DXY leg INSIDE the strict flat bar (+0.28% by 0.02pp), control INCOMPLETE not failed; gate 5 UNTESTABLE session-one but a LIVE sequence — a 2nd >±10 tomorrow could TRIP it, the first since 08-31` · `WEDNESDAY FOMC is the front's disambiguator`
