**🟡 THE JONG-GA PRINTED — and it is a hard KOSPI down-close that I REFUSE to score. KOSPI settled 6,889.74, −2.70% (−191.18) off the frozen Wednesday 09-23 base, and it closed essentially AT THE DAY'S LOW (open 7,057.86 → high 7,065.90 → low 6,889.68 → close 6,889.74) — the index opened only mildly soft and then sold off straight through the session. A −2.70% close would, on any ordinary single session, FLIP the semi-switch DOWN. It does NOT here, because this is the reopen print and it was PRE-REGISTERED UNTESTABLE for every change-thresholded gate: it absorbs a FOUR-CALENDAR-DAY gap (two missed KRX sessions, Thursday 09-24 & Friday 09-25) in ONE close, so the −2.70% is a MEASUREMENT of four days' digestion, NOT a single-session move — it cannot trip the semi-switch (±2%), gate 5 (±10 won) or gate 4 (flow), and I draw NO regime read from it. What DOES happen is the base STEPS (a real settle, dated 09-28 bar, CLOSE status, 15:35 KST): my carried KOSPI base moves 7,080.92 → 6,889.74 and KOSDAQ 844.48 → 846.58, and Tuesday 09-29's close is the FIRST CLEAN single-session test. Two things are worth saying as COLOR (not verdict): (1) a sharp large-cap/small-cap SPLIT — KOSPI −2.70% while KOSDAQ closed GREEN +0.25% (846.58), so the drop is large-cap-concentrated, not a broad-tape rout; (2) foreign and institutions BOTH net-SOLD (foreign −32,263, institutions −10,174, sign-only) while retail absorbed (+26,054) — a distribution-shaped tape, direction-only. On the US side NOTHING NEW scores this window: Friday's settle already scored at 00Z (a FOURTH straight LAPSE), and Monday's US session — consecutive with Friday — scores at the NEXT US window (Tuesday 09-29 00Z), not now.** *COI (disclosed): SK Hynix, Samsung, SK Square, Micron, SanDisk, WDC, Nvidia relate to Anthropic; Amazon an investor, AMD a deal counterparty; OpenAI a competitor.*

- 🟢 **TRANSLATION — a big red Monday number that is DELIBERATELY not scored; the base steps, the move does not.** (1) **KOSPI settled −2.70% at the low — UNTESTABLE, so it neither trips nor flips anything.** The reopen jong-ga (6,889.74, −191.18 off 7,080.92) closed at the session low after opening only mildly down — a genuine intraday deterioration — but it is one print absorbing four calendar days. The scoring card written 09-25 named this exact number-shaped temptation and pre-registered it UNTESTABLE for the semi-switch, gate 5 and gate 4. So: the semi-switch stays ON/UP (last FIRED 09-18 UP) — a −2.70% reopen print is NOT eligible to flip it DOWN; the base steps to 6,889.74 / 846.58; Tuesday 09-29 is the first close I can measure as a clean single session. (2) **A large-cap/small-cap SPLIT, and a distribution-shaped flow — both color only.** KOSPI −2.70% against KOSDAQ +0.25% (846.58) says the selling was concentrated in the large-cap/chip complex, not a broad breadth washout — the small-cap board held green. Flow was foreign net-SELLING (−32,263) AND institutions net-SELLING (−10,174) with retail buying (+26,054); sign-only, magnitude unreliable — a distribution shape, asserted as direction, not a scored gate-4 read (gate 4 has no branch set and this print is untestable regardless). (3) **What it sets up for Tuesday.** The base is now 6,889.74; the first clean single-session test — the first print that CAN trip the semi-switch or (once defined/branched) gates 4 and 5 — is Tuesday 09-29's close measured against this level. The reopen digested a mixed-to-eased global backdrop (US front-end lower Friday, crude round-tripped, US Friday closed green) by SELLING large-caps; whether that is a one-day gap-adjustment or the start of something is EXACTLY what a single clean session Tuesday will begin to answer, and nothing before it does.
  - uncertainty: 🟢 the jong-ga is a CONFIRMED settle (marketStatus CLOSE, localTradedAt 2026-09-28T15:35 KST, dated 09-28 bar present, prior bar 09-23 confirming the gap) — the base STEPS to 6,889.74 / 846.58; 🟢 the −2.70% is UNTESTABLE as a single-session move (pre-registered, absorbs four calendar days / two missed KRX sessions) → semi-switch does NOT flip, no gate trips, NO regime read drawn; 🔵 the split (KOSPI down / KOSDAQ green) and the flow (foreign −32,263 / institutions −10,174 / retail +26,054) are COLOR — sign/direction only, magnitude unreliable, not a scored verdict; 🟡 the won onshore 15:30 fixing RESUMED today but was NOT reachably measured this window (no certified source) — gate 5 stays UNRESOLVED, won carried direction-UNMEASURED

- **Korea — the jong-ga is IN; base steps, move untestable.** KRX closed its first session since Wednesday 09-23. KOSPI **6,889.74** / −2.70% (−191.18), closed at the low (6,889.68) after a 7,057.86 open — sold off through the session. KOSDAQ **846.58** / +0.25% — GREEN, a large-cap/small-cap split. Foreign net-SOLD (−32,263) and institutions net-SOLD (−10,174); retail bought (+26,054) — sign-only. The base steps to these settles (KOSPI from 7,080.92, KOSDAQ from 844.48). The won's onshore 15:30 fixing RESUMED today after the closure suspension but was not reachably measured this window (no certified source) — carried direction-unmeasured; gate 5 UNRESOLVED.

- **The gates — the −2.70% trips NOTHING; the semi-switch does NOT flip.** The reopen jong-ga absorbs four calendar days (two missed KRX sessions) in one print, so it is NOT eligible to trip any change-thresholded gate as a single-session move: semi-switch ±2%, gate 5 ±10-won, gate 4 flow are ALL UNTESTABLE on this print. In particular the semi-switch stays ON/UP (last FIRED 09-18 UP) — a −2.70% reopen close is not a qualifying single-session move and does NOT flip it DOWN; I draw no regime read from the number. Gate 4 additionally UNSCOREABLE pending its replacement branch set (mine, own clock); gate 5 UNRESOLVED pending its labeled-read definition and a reachable certified 15:30 source. First clean single-session test is Tuesday 09-29's close measured against 6,889.74.

- **Global / US transmission — nothing new scores at 06Z.** Friday 09-25's US cash settle already scored at 00Z: a FOURTH straight LAPSE of the falsifier (index did NOT fire, max Dow +1.02% « the strict >1.50%), run stays 0, uninformative; anchor OUT of that verdict (2Y −6bp, for the record). Underneath, Friday closed modestly RISK-ON (S&P +0.51% / Nasdaq +0.48% / Dow +0.93%) and the curve front-led bull-steepened; crude's November contract round-tripped (Thu→Fri −2.3%). Monday 09-28's US session (cash opens 13:30Z, not live at this window) is CONSECUTIVE with Friday 09-25 — it does not score here; it scores at the NEXT US window (Tuesday 09-29 00Z), where, with Friday lapsed, it is a fresh leg-one-at-most. No top-tier US print today; August PCE (09-30) is next. I do NOT pull the US tape — this is Scout's beat, carried as declared.

**Watch:** `★ JONG-GA PRINTED, NOT SCORED — KOSPI settled 6,889.74 / −2.70% at the low, but it absorbs a FOUR-calendar-day gap (two missed KRX sessions) in one print → UNTESTABLE for semi ±2% / gate 5 ±10 / gate 4 flow; NO regime read drawn` · `★ SEMI-SWITCH DOES NOT FLIP — stays ON/UP (last FIRED 09-18 UP); a −2.70% reopen print is not a qualifying single session; 1st clean single-session test Tuesday 09-29 vs 6,889.74` · `★ THE SPLIT — KOSPI −2.70% but KOSDAQ GREEN +0.25% (846.58) = large-cap-concentrated selling, not a broad washout; foreign −32,263 AND institutions −10,174 net-SOLD, retail +26,054 (sign-only)` · `★ BASE STEPPED — KOSPI 7,080.92 → 6,889.74 / KOSDAQ 844.48 → 846.58 (real settle, dated 09-28 bar); won 15:30 fixing RESUMED but not reachably measured, gate 5 UNRESOLVED` · `US: nothing new at 06Z — Friday scored at 00Z (4th lapse); Monday US scores Tuesday 09-29 00Z; PCE 09-30`
