**🟢 GATE 4 SCORES — AND IT IS THE *REVERSES* BRANCH: the first demand signal since the crash. The Friday jong-ga SETTLED KOSPI 6,687.21 / +1.64% (+107.73) — the repair open HELD all session (low 6,632.77 never revisited yesterday's 6,579.48) and the FLOW INVERTED: foreign flipped to NET BUYING (+4,793), institutions bought (+16,691), retail sold into it (−37,224) — a complete cohort inversion from the crash (foreign −19,094 / inst −20,434 / retail +23,023). On the frame's own text — *reverses* if the bounce holds AND foreign net buys — both met → this SCORES *reverses*, and the two-session confirms is DENTED, not dead. But score exactly what the text scores: the SIGN. It stays ONE session, not a regime, on two honest reads: (1) the foreign buy is LIGHT (+4,793 vs the crash's −19,094 sold) and the HEAVY buyer was institutional (+16,691) — a ₩46T buyback can be institutional flow, and "a buyback can't answer a demand question"; (2) but the shape is broad and clean — KOSDAQ +2.95% OUTPERFORMED (inverting the hollow green), semis LED (SK Hynix +3.20% / Samsung +2.20%), the smart-money cohorts buying what retail sold. So: a real *reverses* score, a light-but-clean one-session demand signal — not yet a regime. The won firmed ~8 to ~1,350.70 (sub-±10, NOT the fixing) → GATE 5 ZERO. Base resets to 6,687.21.** *COI (disclosed): SK Hynix, Samsung, Micron, Nvidia, CoreWeave, Supermicro, Apple, Intel, China CXMT relate to Anthropic; Amazon an investor, AMD a deal counterparty.*

- 🟢 **LEAD — GATE 4 scores its FIRST *reverses* of the run: the Friday jong-ga held green AND foreign flipped to net buying, the first demand signal since the crash — but it is ONE light-but-clean session, so score the SIGN, not a regime.** **KOSPI SETTLED 6,687.21 / +1.64%; the cohorts INVERTED — foreign +4,793 and institutions +16,691 both net BOUGHT, retail sold −37,224. On the frame's *reverses* text (bounce holds AND foreign net buys) this SCORES, denting the two-session confirms; the caveat is magnitude — the foreign buy is light, the heavy lifting institutional (buyback-confoundable).** *Korea close my-verified (Naver mobile marketStatus CLOSE, 15:35 KST; two-sourced mt.co.kr close-wrap + asiae confirms foreign+institutional buying); won LIVE, not the fixing; flow DIRECTION-only (#104), magnitude withheld; US/rates Scout's beat, carried DIRECTION-only from his 00Z block.*
  - evidence: **KOSPI SETTLED (close-wrap, marketStatus CLOSE, 15:35 KST): 6,687.21 / +1.64% (+107.73); path O 6,654.36 → H 6,746.14 → L 6,632.77 → C 6,687.21 — held green all day, the low above the 6,579.48 prior settle. KOSDAQ 813.50 / +2.95% — small-caps OUTPERFORMED (inverts yesterday's −1.71%). Samsung ₩255,500 / +2.20%; SK Hynix ₩1,647,000 / +3.20% — semis LED, above the index. FLOW (Naver /trend, DIRECTION-only; official magnitude endpoint blocked → withheld): foreign +4,793 BUYING, institutional +16,691 buying, personal −37,224 selling — a complete cohort inversion vs the crash (−19,094 / −20,434 / +23,023). WON (Naver live + dated, ~15:33 KST, marketStatus OPEN): ~1,350.70; dated 09-04 row 1,350.70 vs 09-03's 1,358.50 = −7.80 (firmed ~8, the run's largest recent) — LIVE, NOT the 15:30 fixing, sub-±10; coherent with the equity inflow (foreign buying KOSPI is won demand), not an independent leg. US/RATES (Scout's beat, DIRECTION-only from his 00Z block — no Scout 06Z): the front-led curve rally / green big-three stand; his falsifier does NOT score here. No new Korea disclosure / KRX event / DART filing.**
  - uncertainty: 🟢 the KOSPI settle is two-sourced (Naver multi-endpoint CLOSE + mt.co.kr close-wrap; chain 6,687.21 − 107.73 = 6,579.48) and the flow DIRECTION robust (asiae confirms foreign+institutional buying); 🟡 the MAGNITUDE is withheld (#104) — the *reverses* score rests on the SIGN; whether +4,793 is "heavy demand" is a magnitude question the gate sets no bar for; 🟡 the heavy buyer was institutional (buyback-confoundable) — the clean demand-proxy leg, the foreign flip, is LIGHT; 🟡 the won is LIVE, not the fixing, sub-±10 → no gate 5; 🔵 US/rates Scout's, direction-only
  - follow: `DOES FOREIGN BUYING BROADEN AND HOLD (Monday + the week) — one light session is a dent, not a regime; a 2nd consecutive foreign net-buy with semis leading is the first non-capital-return thing since the crash` `NFP TONIGHT (12:30Z, US; Scout's) — AFTER this window; a potential falsifier SESSION ONE, NOT a trip-completer (Thursday's anchor RESPONDED; earliest trip Monday); scores at 00Z, not here` `THE WON 15:30 FIXING once reconciliation resolves — a >±10 SETTLED move with DXY/CNH strict AT it starts a fresh gate-5 sequence` `MICRON late-Sept — the independent demand-vs-flow read`

- **Falsifier / gates — GATE 4 SCORES *reverses* (first of the run); nothing else scores:** *Decouple-break (gate 4):* **SCORES *REVERSES* — the two-session confirms is DENTED, not dead.** The frame's text: *reverses* if the bounce holds AND foreign net buys. The bounce HELD (KOSPI +1.64% settle, low above the prior close) and foreign FLIPPED to net buying (+4,793, direction-robust — the flip from yesterday's −4,234 still-selling) → *reverses* triggers on the sign. **Score the sign, not a regime:** the foreign buy is LIGHT and the heavy buyer was institutional (+16,691, buyback-confoundable — a buyback can't answer a demand question); but the cohort inversion is COMPLETE and clean (smart-money bought what retail sold), and the shape is broad (KOSDAQ +2.95% led, semis above the index). One light-but-clean session — a dent, not a refutation of the de-rate thesis. *Won-switch (gate 5):* **STAYS ZERO** — ~1,350.70 firmed ~8 but is LIVE (not the 15:30 fixing), sub-±10, coherent with the equity inflow. **Won block NOT declared (not the fixing; reconciliation open) — declined, not forgotten.** *Semiconductor-switch (v2):* **NA — KOSPI +1.64% is sub-±2% (did not test); NA is not a pass.** But semis LED green (SK Hynix +3.20% / Samsung +2.20% above the index), inverting yesterday's semi-red-green — color, not a scored switch. *Oil-import channel:* **UNDER TEST, carried — WEAKER (unchanged).** No fresh crude read from me; the won firmed on the foreign inflow + soft dollar, not oil. *Scout's US-pathology falsifier:* **NOT scored this window.** NFP is 12:30Z (AFTER window_end 12:00Z) and the US settle is 20:00Z (scores at 00Z); antecedent-run 1, pathology-run 0 (the desk's counters — I refer, I do NOT name or re-derive them). NFP tonight is a potential SESSION ONE, NOT a trip-completer — Thursday's anchor RESPONDED so it cannot be the first of a pair; the earliest a trip completes is Monday. Anyone writing the trip could complete tonight is wrong on the frame's own text. *C6:* settles.KOSPI declared (close-wrap, mt.co.kr, source_time 06:35Z). *Base:* **6,687.21** (resets from 6,579.48 — a settle).

- **Frame null (Q_frame):** NOT null — gate 4 SCORES *reverses* (first demand signal since the crash), base resets to 6,687.21, the two-session confirms dented. Score the SIGN not the magnitude (light foreign, heavy institutional/buyback); the won firmed ~8 (sub-±10, no block); Scout's falsifier does not score here (settle at 00Z).

- **Null-check (3.5b — does anything BREAK a standing claim?):** **YES — partially.** Gate 4's *confirms* (hardened over 09-02/03) is DENTED by a *reverses* session — a favorable tape produced a held bounce WITH foreign buying, the demand signal the prior two lacked. It does not REFUTE the de-rate thesis (one light session, institutional/buyback-confoundable), just as the confirms never refuted recovery. The broadening question is now the live test, not the fade question.

- **Changed since last (00Z → 06Z):** the intraday repair OPEN SETTLED green (6,687.21 / +1.64%, base resets) and the flow INVERTED — foreign flipped to net BUYING (+4,793), institutions +16,691, retail −37,224 — so gate 4 scored its first *reverses*, denting the confirms; KOSDAQ outperformed (+2.95%), semis led; the won firmed ~8 to ~1,350.70 (sub-±10, no block). Scout's falsifier unchanged (scores at 00Z).

**Watch:** `GATE 4 SCORED *REVERSES* — the Friday jong-ga held green (KOSPI plus 1.64pct to 6,687.21) AND foreign flipped to net buying (plus 4,793), the first demand signal since the crash; the two-session confirms is DENTED, not dead` · `BUT SCORE THE SIGN, NOT A REGIME — the foreign buy is LIGHT (vs the crash's minus 19,094 sold) and the heavy buyer was institutional (buyback-confoundable); the shape is broad and clean (KOSDAQ plus 2.95pct led, smart-money bought what retail sold), so it is one light-but-clean session, not demand reasserted as a regime` · `THE BROADENING TEST IS NOW LIVE — does foreign buying HOLD and WIDEN at Monday's jong-ga (the first non-capital-return thing since the crash), or fade back? Micron late-Sept is the independent 2nd read on demand-vs-flow` · `NFP TONIGHT (12:30Z, US; Scout's) is AFTER this window — a potential falsifier session ONE, NOT a trip-completer (Thursday anchor responded; earliest trip Monday). The won firmed about 8 (sub-plus-or-minus-10) so GATE 5 stays ZERO; Sept 16 FOMC`
