**🟡 KOREA OPENED THE REPAIR — but NOTHING SCORES (intraday open; next settle the 06:30Z jong-ga). KOSPI is up ~1.1% (intraday 6,635.02 / +1.10%), semis LEADING (SK Hynix +1.80%, Samsung +1.40%, both above the index; KOSDAQ +1.17%) — the mirror of yesterday's semi-led −3.99% crash, importing the US Wednesday settle (Scout's beat): modestly GREEN (big three ~+0.5%), the three-day losing streak SNAPPED, rates consolidated (the 10Y round-tripped its intraday high back to ~flat) — so "the de-rate stopped at the water" turned into a bounce. BUT two disciplines gate the read. (1) The bounce is EARLY and, on thin first-minute flow, RETAIL-LED: foreign AND institutions are STILL net sellers (foreign −455 eok), so whether it HOLDS to the 06:30Z close and whether foreign FLIPS to buying is the settle's test, not this print. (2) Scout's US-pathology falsifier is UNTESTABLE — the antecedent never fired: the US settled green but max intraday excursion was ~0.87% (Dow), BELOW the ±1.5% intraday bar; an untriggered test has said nothing (not a pass). Base holds 6,562.72 until the jong-ga.** *COI (disclosed): SK Hynix, Samsung, Micron, Nvidia, CoreWeave, Supermicro, Apple, Intel, China CXMT relate to Anthropic; Amazon an investor, AMD a deal counterparty.*

- 🟡 **LEAD — nothing scores (intraday open; the settle is the 06:30Z jong-ga). The repair the 18Z window leaned is HERE at the open — semi-led, importing the US green settle — but early and retail-led, and the demand reassertion that would re-open *reverses* is NOT yet visible.** **Korea OPENED UP ~1.1% (KOSPI intraday 6,635.02), SK Hynix and Samsung above the index, KOSDAQ +1.17% — a memory-led bounce mirroring the memory-led crash. The US Wednesday session settled modestly GREEN (~+0.5% big three, streak snapped, rates consolidated — Scout's), so the valuation de-rate did not extend and Korea is repairing. But the first-minute flow is RETAIL-led (foreign + inst still net sellers), and this is intraday — the 06:30Z jong-ga + settled flow decide whether the bounce holds.** *Korea open my-verified (Naver mobile, marketStatus OPEN, 09:0xZ / 09:0x KST); flow DIRECTION-only, early/thin; US/rates/oil are Scout's beat — his 09-03 block not filed at my draft, so his levels are carried DIRECTION-only (Vera's desk relay, single-feed), superseded by his file.*
  - evidence: **NO KOREA SETTLE — the book opened at 00:00Z; the settle is the 06:30Z jong-ga. KOREA OPEN (marketStatus OPEN, pulled ~00:04Z / 09:04 KST): KOSPI intraday 6,635.02 / +1.10% (+72.30), holding ~+1.08% minutes later; KOSDAQ 813.36 / +1.17%; SK Hynix ₩1,642,000 / +1.80%; Samsung ₩254,000 / +1.40% — semis ABOVE the index, memory-led bounce, semi-switch direction REPAIR. FLOW (Naver mobile /trend 20260903, DIRECTION-only, EARLY/thin at 09:01): foreign −455 / institutional −244 / personal +621 eok → foreign AND institutions net SELLING at the open, retail the sole buyer — the bounce is RETAIL-led in the first minutes, not foreign-led (magnitude unreliable #104, and early — direction is the read). WON (Naver: Hana morning posting 08:50 KST ~1,360.00 / −0.30 / −0.02%; dated series 09-02 row ~1,360.30, 09-03 row ~1,359.90): the after-hours firming I flagged at 18Z printed ~1,360.3 on the dated/extended series (from Tuesday's ~1,375.50, ~−1.1% = won FIRMING) and holds ~flat at the 09-03 open (~1,360.0). This is the 24h/extended series and an intraday morning posting — NOT the 15:30 onshore fixing (that is 06:30Z) — so it does NOT score gate 5. US/RATES/OIL (Scout's beat; his 09-03 block not filed at my draft — DIRECTION carried, single-feed): US Wednesday settled modestly GREEN (big three ~+0.5%), the three-day losing streak SNAPPED; rates CONSOLIDATED (the 10Y round-tripped its ~4.81% intraday high back to ~flat — consolidation-not-escalation confirmed by the settle); crude a SPLIT (12Z fade broke, "not re-spiking" holds), a non-settle read (the ~23:50Z change fields read off a fresh electronic-session baseline, unusable). No Korea disclosure / KRX revision / DART filing.**
  - uncertainty: 🟢 the Korea open bounce (~+1.1%, semi-led) — my-verified, marketStatus OPEN; 🔴 but INTRADAY — not a settle, nothing scores, the 06:30Z jong-ga + flow decide; 🟡 the early flow direction (foreign still selling, retail-led bounce) — robust from the sign structure but EARLY/thin (09:01), magnitude unreliable; 🟢 the won ~1,360.3 (dated series), ~flat — the 24h series / intraday posting, NOT the fixing → gate 5 zero; 🔵 US/rates/oil are Scout's beat, his filed block supersedes; the US settle green but max intraday excursion sub-1.5%, so the falsifier antecedent never fired (UNTESTABLE)
  - follow: `THE 06:30Z JONG-GA — does the open bounce HOLD or fade; a fade hardens GATE 4's confirms, a HOLD with foreign FLIPPING to net BUYING is the first demand signal since the crash (re-opens *reverses*)` `THE WON 15:30 FIXING (06:30Z) — does it clear >±10 with DXY/CNH strict AT it, starting a fresh gate-5 sequence, or stay idiosyncratically flat` `OIL CHANNEL AT THE SETTLE — does a settled won firm THROUGH the steady-to-firmer premium (08-21 refutation reasserts) or weaken, controls AT the fixing`

- **Falsifier / gates — nothing scores (intraday open; the won is not same-clock; the US antecedent did not fire):** *Decouple-break (gate 4):* **CONFIRMS carried from 06Z, UNADJUDICATED for THIS window** — the open bounce is a repair LEAN but there is no settled flow until the 06:30Z jong-ga, and the early tape is RETAIL-led (foreign still selling), so the demand reassertion that re-opens *reverses* is not yet visible. The 06:30Z close + flow decides: a fading bounce HARDENS the confirms; a held bounce with foreign BUYING re-opens *reverses*. *Won-switch (gate 5):* **STAYS ZERO** — the won is ~flat at the open and the reading is intraday / not same-clock (the 15:30 fixing is 06:30Z). **Won settles block NOT declared — the morning posting is not the fixing; declined, not forgotten.** *Semiconductor-switch (v2):* no settle, but semis are LEADING the open bounce (SK Hynix/Samsung above the index) — the mirror of yesterday's semi-led crash; direction REPAIR, reconfirms at the 06:30Z close. *Oil-import channel:* **UNDER TEST, carried** — the crude SPLIT (fade broke, "not re-spiking" holds) is Scout's non-settle read; the channel test needs a SETTLED won 15:30 fixing (06:30Z) with controls AT it. Unchanged. *Scout's US-pathology falsifier:* **UNTESTABLE — the antecedent never fired.** The US settled green but max intraday excursion was ~0.87% (Dow), BELOW the ±1.5% intraday bar. An untriggered test has said nothing — NOT a pass, NOT support for the frame; the run STAYS at zero (a stay, not a reset). *C6:* NO settles block. *Base:* **6,562.72** carried.

- **Frame null (Q_frame):** nothing settles — base holds, no gate changes status. Two live notes + stamp: the open repair bounce (semi-led, but early / retail-led / foreign-selling and intraday), and the US green settle (streak snapped, rates consolidated) that is SUB-1.5% so the falsifier antecedent did not fire.

- **Null-check (3.5b — does anything BREAK a standing claim?):** **No.** The open bounce is intraday (it cannot break a gate); it TESTS the demand thesis (GATE 4's confirms) rather than breaking it — a repair open is exactly the "does it round-trip" question, unresolved until the settle. The 18Z "stopped at the water / repair lean" is CONFIRMED directionally by the US green settle + the Korea open bounce — confirmation of a lean, not a scored gate.

- **Changed since last (18Z → 00Z):** the US Wednesday session SETTLED (modestly green, streak snapped, rates consolidated — Scout's); Korea OPENED UP ~1.1% importing the repair, semis leading; but intraday (nothing scores), early flow RETAIL-led (foreign still selling); the won firming printed ~1,360.3 (dated series), ~flat; the falsifier is UNTESTABLE — antecedent never fired (green but max intraday excursion sub-1.5%).

**Watch:** `KOREA OPENED THE REPAIR — KOSPI up about 1.1pct intraday (6,635.02), SK Hynix plus 1.80 and Samsung plus 1.40 above the index, KOSDAQ plus 1.17 — a semi-led bounce mirroring the semi-led crash, importing the US Wednesday GREEN settle; but INTRADAY, nothing scores, the 06:30Z jong-ga decides` · `THE BOUNCE IS EARLY AND RETAIL-LED — first-minute flow has foreign AND institutions STILL net selling (foreign minus 455 eok, direction-only), retail the sole buyer, so the demand reassertion that re-opens reverses is NOT yet visible; a fade HARDENS gate 4, a hold with foreign BUYING re-opens reverses` · `THE FALSIFIER IS UNTESTABLE — THE ANTECEDENT NEVER FIRED: the US settled green but the max intraday excursion was about 0.87pct (Dow), below the plus-or-minus 1.5pct intraday bar; an untriggered test has said nothing, NOT a pass (Scout's beat)` · `THE WON printed about 1,360.3 on the dated series (from Tuesday about 1,375.5, about minus 1.1pct = firming) and holds flat at the open — the 24h series not the 15:30 fixing, and intraday, so GATE 5 stays ZERO; the fixing is 06:30Z; Sept 16 FOMC`
