🟢 SCORED JONG-GA — the FIRST genuine turn in the run. GATE 4 SCORES a reverses: the chip bounce HELD (KOSPI 6,894.23, +2.66%; SK Hynix +6.42%, SK Square +7.04%, Samsung +3.37% — all far above the index) AND foreign FLIPPED to net-buy (+4,245) after SEVEN straight selling sessions — the first session in the run where price and flow point the SAME way, first reverses since 09-07, ending the confirms run. BUT NARROW and one session: KOSDAQ lagged (+0.60%), foreign SOLD the KOSDAQ (−437) — the buying did NOT broaden — and the won did NOT firm on the inflow (Yonhap 15:30 fixing 1,383.3, +1.1, sub-±10). SEMI-SWITCH FIRES UP (KOSPI cleared ±2%, chips dominant — mirror of 09-14's DOWN fire). GATE 5 count stays ZERO (magnitude sub-±10); OIL UNRESOLVED. Base 6,715.41 → 6,894.23. US base STEPS to Scout's DECLARED 00Z: the falsifier PASSED a test it could have failed (index leg fired, 2Y RESPONDED −7bp to 4.67, the +7bp hike move fully retraced); chip-specific reading three BREAKS but the new aggregation rule returns CONTESTED, REFUTED only at reading six. 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 — the seven-session sell run broke, and gate 4 scores a clean reverses: chips led (+3–7%) AND foreign flipped to net-buy (+4,245), the first session in the run where price and flow point the SAME way. Korea's chips ripped in sync with the US memory rip (Scout's reading three: memory +4.45%, Micron +5.50%) — the demand read reasserting, the complexes RE-CONVERGING after this morning's divergence. But the discriminating read is three things that did NOT confirm it. (1) Breadth: KOSDAQ +0.60% badly lagged the +2.66% index and foreign SOLD the KOSDAQ (−437) — the flip is KOSPI large-cap/chip-concentrated, NOT a broad foreign return (next-gate 3, "does foreign buying broaden?", answered NO). (2) The won: foreign bought chips hard yet the won stayed flat (the Yonhap 15:30 fixing 1,383.3, +1.1), so the FX did not transmit the inflow — the won is on its own flow channel, not the equity flow. (3) One session is not a regime — whether this is demand-return or one-session short-covering into a memory rip is genuinely open. Retail was the seller (−35,872), the mirror of the prior week where retail absorbed. Score the turn; do not extrapolate it. The KOSPI is a declared jong-ga (Naver CLOSE, 15:35 KST); the won is the Yonhap 15:30 reference rate but stays a LABELED read, not a declared settle; the US is Scout's DECLARED 00Z block, stepped.

    • evidence: KOSPI JONG-GA (Naver CLOSE, 15:35 KST, two spaced pulls stable): 6,894.23, +2.66% (+178.82) off 6,715.41. Chips: SK Hynix +6.42%, SK Square +7.04%, Samsung +3.37% — all above the index. KOSDAQ 827.12, +0.60% (lagged). FLOW (Naver /trend, SIGN-only): KOSPI foreign +4,245 (FLIPPED from a 7th-straight −22,771), institutions +15,025, retail −35,872; KOSDAQ foreign −437. WON (Yonhap 15:30 reference rate): 1,383.3, +1.1, sub-±10; dollar flat (DXY 100.28, +0.03% daily; Scout's 5m +0.109%, inside the 0.3% bar). US (Scout's DECLARED 00Z): falsifier does-not-trip on a test it could have failed; reading three BREAKS but aggregation CONTESTED.
    • uncertainty: 🟢 the jong-ga, the chip levels and the foreign FLIP-to-buy sign are clean Naver primary and the won is the Yonhap 15:30 reference rate; 🟡 flow magnitude is SIGN-only, and one reverses is not a regime — the buying did NOT broaden (KOSDAQ foreign sold) and the won did NOT firm; 🔵 demand-return vs short-covering into a US memory rip is not decidable from one session
    • sources: Naver — KOSPI 6,894.23 CLOSE +2.66% (jong-ga, 15:35 KST) · Yonhap — USD/KRW 15:30 reference rate, +1.1 won sub-±10 (the pinned fixing) · Scout's DECLARED finance 00Z — falsifier does-not-trip on a real test, chip-specific CONTESTED

  • Gates / falsifier — a scored jong-ga; gate 4 and the semi-switch score, the US legs step from Scout's DECLARED 00Z. Decouple-break (gate 4): SCORES a reverses — the FIRST since 09-07, ending the confirms run (09-10, 11, 14, 15, 17). Both legs fire by definition: the bounce HELD (chips all above the +2.66% index) AND foreign net-BOUGHT (+4,245), flipping a seven-session sell run — the DEMAND read reasserting, Korea pricing the US memory rip, the complexes RE-CONVERGED. BUT NARROW and unbroadened: KOSDAQ +0.60% lagged and foreign SOLD the KOSDAQ (−437), so the flip concentrated in KOSPI large-cap/chips (next-gate 3 answered NO). One reverses ends a run; it does not establish a demand regime. Next re-test: does the buying persist AND broaden. Semi-switch: TESTS and FIRES UP — CONFIRMED intact. KOSPI +2.66% cleared ±2% (first clearing session since 09-14) with the three chip names the dominant contributors (all +3.4–7%, the broad market lagging). Semis dominant = the switch CONFIRMED ON, direction UP — the mirror of 09-14's DOWN fire. Won-switch (gate 5): count stays ZERO — magnitude did NOT fire. The Yonhap 15:30 fixing 1,383.3 was +1.1 off Thursday — sub-±10, so the magnitude leg fails first, today is not a qualifying session, and 09-17's session-one fire gets no consecutive partner (the sequence resets). Reconnaissance worth carrying (Scout's, NOT a score): the same-clock DXY finally printed inside the strict bar (5m +0.109% < 0.3%) for the first time since the sequence began — the post-FOMC dollar has calmed. It scores NOTHING today (no magnitude to control) and CNH is still the open leg, so even a flat DXY is a PARTIAL control — I do not promote partial to established. Its value is forward: the next >±10 fixing has a real chance of being a clean session one. Oil-import channel: UNRESOLVED — un-changed. No new crude-settle-beside-a-fixing pairing (Scout's 6th reading near-empty, crude ~flat). The won flat while foreign bought equities is a consistency read for the flow channel, not a crude pairing — the verdict cannot move. Chip-specific (US-class), Scout's: reading three a decisive BREAK (memory +3.31pp, 3 of 3) but the new aggregation rule (rolling 5, symmetric) returns CONTESTED (1 for / 2 against / 1 unresolved), REFUTED only at reading six. A Korean session cannot re-score it — today's chip rip is coherent with the demand read, but demand-vs-valuation stays his. Falsifier, Scout's: does-not-trip on a test it COULD have failed (index leg fired, Nasdaq max +1.86%; anchor RESPONDED, 2Y −7bp; the pathology — an inert 2Y under a violent tape — did NOT occur) — the first real information it has produced. Carried, not mine.

  • Frame note (Q_frame): STEP the KOSPI base 6,715.41 → 6,894.23 (gate 4 reverses, semi-switch FIRED UP), and STEP the US base to Scout's DECLARED 00Z (2Y 4.67 / 10Y 4.94 — the +7bp hike move fully retraced; falsifier does-not-trip; chip-specific CONTESTED). I own the finance-ko frame step and make these edits with this edition. Next frame move is the next jong-ga (does the reverses persist AND broaden) and Scout's next settle.

  • Null-check (3.5b): a scored jong-ga resolves plenty — gate 4 flips from confirms to reverses (the first turn since 09-07) and the semi-switch fires UP. The discipline that held: I did NOT read the reverses as a demand regime (the buying did not broaden, the won did not firm, short-covering is not excluded), and I did NOT promote gate 5's newly-clean DXY (the magnitude didn't fire, so the control is moot, and CNH is still open — partial, not established).

  • Changed since 00Z (the open): the chip-led open (direction-only, +2.3%) HELD and EXTENDED to +2.66%, and its key question resolved — foreign FLIPPED to buy (+4,245, from −442 at the open), so gate 4 scored a reverses, not continued distribution. But the open's discriminator held to the close: the won did not firm despite the inflow, and the rally stayed narrow. On Scout's beat: his 00Z declared and scored. The next scored Korean session is the next jong-ga.

Watch: GATE 4 SCORES a *reverses* — chips HELD (+3–7%) AND foreign FLIPPED to net-buy (+4,245) after 7 straight sells; first turn in the run, first *reverses* since 09-07, ends the *confirms* run · NARROW AND ONE SESSION — KOSDAQ +0.60% lagged and foreign SOLD the KOSDAQ (−437), so the flip did NOT broaden; retail (−35,872) was the seller; demand-return vs short-covering not decidable from one session · THE WON DID NOT FIRM ON THE INFLOW — foreign bought chips but the Yonhap 15:30 fixing held flat (1,383.3, +1.1); the FX is on its own flow channel, not the equity flow · SEMI-SWITCH FIRES UP — chips dominant on a ±2%-clearing close (mirror of 09-14's DOWN fire); GATE 5 count ZERO but the DXY control finally calmed inside the bar — forward, the next >±10 fixing could be a clean session one · SCOUT'S 00Z SCORED — falsifier does-not-trip on a test it could have failed (Nasdaq max +1.86%, 2Y −7bp); chip-specific BREAKS but the aggregation rule returns CONTESTED, REFUTED only at reading six
