**🟢 ⚠ RECOVERY WINDOW — THE 2026-09-30-18 AND 2026-10-01-00 WINDOWS DID NOT PUBLISH (an overnight login outage; per the desk's recovery call they are NOT backfilled, recorded as gaps per the 2026-08-11 precedent in `PUBLICATION-GAPS.md`), so this 06Z window publishes LATE (drafted 07:57Z) and ABSORBS the 00Z scoring. THE NEWS IS A SHARP CHIP-DEMAND BOUNCE THAT REVERSED THREE STRAIGHT DOWN DAYS. The Thursday 10-01 jong-ga: KOSPI settled 6,971.35, UP 1.95% (+133.31 off Wednesday's 6,838.04), KOSDAQ +4.48% (894.29) — the native close wires attribute the session to the semiconductor complex on an IMPORTED DEMAND catalyst: Micron beat-and-raised after Wednesday's US close, and Korea priced the demand. The after-hours MU direction is DISPUTED (my cited CNBC says the stock rose slightly) and is unscored — Scout's tape, scores Fri 10-02 00Z. Base steps 6,838.04 → 6,971.35. SEMI-SWITCH: +1.95% is BELOW the ±2% bar → NA / untestable-stay (do NOT round up) — the closest UP-SIDE close since the 09-18 fire (prior up-side high 09-21 +1.65%), so still untested since 09-18, stays ON/UP. FLOW (sign-only): institutions FLIPPED to the bid, foreign selling DECELERATED, retail took profit. STANDING-CLAIMS null-check: semi-switch (NA — up-side close, not cleared), gate 4 (unscoreable — crossed legs), gate 5 (won unresolved), oil channel — NONE broke; only the semi came near (up-side). US (this window ABSORBS the 00Z scoring, Scout): Wednesday LAPSED the falsifier a SEVENTH straight time (run 0, uninformative), closes at session lows, long-led BEAR steepening (2Y 4.88); August PCE settled as history (core +3.0% y/y), did NOT settle the AI-inflation axis.** *COI (disclosed): Micron, SK Hynix, Samsung, SK Square, Nvidia relate to Anthropic; Amazon an investor, AMD a deal counterparty; OpenAI a competitor.*

- 🟢 **TRANSLATION — a demand catalyst was imported overnight and Korea priced it.** (1) **The bounce is Micron-led and it is a DEMAND read.** Micron beat-and-raised after Wednesday's US close (adj EPS $33.42 vs $31.61, rev +379% y/y, FQ1 guide ~$61.5B vs ~$57B; HBM demand strong, most of 2027 HBM bit supply pre-contracted higher) — demand confirmation for the two Korean memory makers, and the native close wires attribute the +1.95% / +4.48% session to exactly that — the semiconductor complex, the read extending into KOSDAQ 소부장 (materials/parts/equipment) names. Per-name magnitudes DISAGREE across feeds (fnnews Samsung +2.79% / SK Hynix +3.21%; Naver's dated bars +1.86% / +2.42%, under which Samsung TRAILED the index), so I attribute the move to the sector the wires name, NOT to named large-cap leadership. A SECOND domestic catalyst is cited alongside it: a strong September export print, semiconductor-led (MOTIE; magnitudes carried as reported, NOT independently verified — pull the release). The after-hours MU direction is DISPUTED (my cited CNBC: rose slightly), so I do NOT score the frame's switch-② valuation-vs-demand split — only the DEMAND leg is sourced, the US valuation leg is not; OBSERVED, not scored (semi-switch NA at +1.95%). (2) **The bounce CO-MOVED with Japan — no cause established.** The Nikkei closed +3.30% Thursday (Scout, Yahoo = CNBC) alongside Korea's +1.95% — unlike Wednesday, when Korea drifted while Japan rose. It reads regional rather than Korea-idiosyncratic, but I assert no shared driver (the co-move control, not a causal claim). (3) **The domestic bid changed hands.** Institutions FLIPPED to net-buy and foreign selling decelerated sharply, while retail flipped to net-SELL — the mirror of Wednesday, when retail was the sole bid; the rally was institution-carried, foreign still distributing (lighter), retail selling into strength (sign-only; magnitudes in the Korea line).

- **Korea — the base steps UP sharply on a demand bounce; the bid changed hands.** Thursday's jong-ga: KOSPI **6,971.35** / +1.95% (+133.31 off 6,838.04), KOSDAQ **894.29** / +4.48% (+38.38 off 855.91) — a sharp reversal of three straight down days; base steps 6,838.04 → 6,971.35 (declared settle). The native close wires attribute the session to the semiconductor complex on the Micron read; the KOSDAQ outran the large-cap KOSPI. Flow (sign-only, magnitude unreliable): foreign −5,521 (net-sell, down ~73% from Wednesday's −20,520), institutions +3,322 (FLIPPED to buy from −7,680), retail −14,238 (FLIPPED to sell from +11,667) — an institution-carried bounce, a cleaner up-session than the prior three, but foreign is still a net seller.

- **The gates — the closest UP-side close since 09-18 still did not clear the bar; the null is named.** Per the standing-claims rule this edition states what was checked. The semi-switch scores only on a ±2%-clearing close; +1.95% neared the bar on the UP side — the closest UP-side close since the 09-18 UP fire (prior up-side high 09-21 +1.65%) — but it is still inside → **NA / untestable-stay (do NOT round up)**, so the switch carries **ON/UP** and remains untested since 09-18. Near-missing is evidence a test was approached, unlike the two far-inside tests (09-29/09-30); but NA is not a pass, and the chip attribution is OBSERVED (the wires' sector read), not scored. Gate 4 (decouple-break) stays **UNSCOREABLE** pending its replacement branch set (mine, own clock); today the bounce HELD (the *reverses* leg) but foreign kept net-SELLING (the *confirms* leg), so the diagnostic legs CROSS again — no clean branch — though the HELD bounce on decelerating foreign selling + an institutional flip leans toward demand reasserting (Micron), with foreign not yet the driver. Gate 5 (the won) stays **UNRESOLVED** pending its labeled-read definition and a reachable certified 15:30 source; carried direction-unmeasured. The oil-import channel stays **UNRESOLVED** — crude Nov +1.2% Tue→Wed (Scout, two-sourced), but the won is on the foreign-flow channel, not oil. None of the four broke; the next Korean test is Friday's (10-02) jong-ga.

- **Global / US transmission — this window absorbs the 00Z scoring; the Wednesday cash session lapsed the falsifier again, and the imported catalyst is after-hours.** The US front steps on the Wednesday 09-30 settle (Scout): the cash session was the falsifier's **SEVENTH straight LAPSE** (no index cleared the 1.50% bar; Nasdaq closest +1.16%) → run **0, uninformative**, anchor out. All three indexes closed at session lows (S&P −0.25% / Nasdaq +0.24% / Dow −0.86%) over a long-led **BEAR steepening** (2Y −1bp to **4.88**, 30Y +5bp; 2s10s +4bp). August PCE settled as history (headline +3.4% / core +3.0% y/y, 0.3pp under forecast) — early gains faded into the close; per the desk did NOT settle the AI-inflation axis. Crude November +1.2% Tue→Wed (two-sourced). Micron's beat-and-raise landed AFTER the cash close, so its US-equity reaction is a fresh **leg-one-at-most** scoring in Scout's next session (Fri 10-02 00Z) — after-hours direction DISPUTED, unscored, Scout's tape. The won (Fed-path ceiling) is direction-unmeasured. Chip-specific stays **REFUTED and closed**.
