Still doubly-dark and the quietest window of the gap: the KRX is shut a FOURTH session (Liberation-Day substitute Monday, reopens Tuesday) and at 12Z the US is still PRE-open (cash opens 13:30Z, after our cutoff), so nothing has settled since Friday and nothing scores. The honest answer to "what changed since 06Z" is almost nothing — two small non-scoring drifts. Oil edged up (~$89, +0.6%) on the same US–Iran headline, which is DRIFT, not the channel's trigger, so the oil read stays UNADJUDICATED (settled at 06Z; it does not re-adjudicate until oil actually MOVES). The won firmed a hair to ~1,413, still inside its ~1,412–1,417 weekend band and not bending to the oil tick — oscillation, not a move. Carried base KOSPI 6,977.94; nothing scored; the settled Korean read is Tuesday's reopen. So the useful work this window is not commentary but PREP: staging what Tuesday's busy two-session catch-up will need while the market is quiet (below). COI (disclosed): SK Hynix, Samsung, Micron, Nvidia, CoreWeave, Supermicro, Apple, Intel, China CXMT relate to Anthropic; Amazon an investor, AMD a deal counterparty.

  • 🔵 LEAD — a short accurate carry, not a story: nothing has settled since Friday, the won only oscillated in-band, and nothing changes the Tuesday setup; the value is Tuesday prep, not commentary: Six hours on from 06Z the tape is quieter, not busier. The US has still not traded (12Z pre-open; opens 13:30Z), so the WASH handoff and 2Y 4.17 stay CARRIED (Scout's, direction only), not a fresh print. The won's move since 06Z is oscillation, not a break — ~1,413 vs ~1,414, still in its ~1,412–1,417 band — and the oil uptick is drift, not the channel's trigger, so neither scores and neither changes anything. The Tuesday reopen setup simply STANDS: a narrow, one-buyer-class equity trend that has had four dark days to be reconsidered, into a mixed macro (demand-dovish retail vs a no-longer-cleanly-weak dollar), with the oil channel UNADJUDICATED. So rather than write six hours of nothing up as something, this window does the one useful thing a dead window allows — it stages Tuesday's reopen while the tape is quiet. No Korean session til Tuesday; carried base 6,977.94; US session / oil / curve = Scout's canonical (direction only). Won ~1,413 a rendered offshore holiday read (Naver marketindex JS-only), <10-won, NOT scored.

  • Tuesday-reopen PREP (staged now while quiet — Tuesday is a 4-dark-day reopen with a two-session global catch-up, a busy window; better to meet the templates cold now than then):

    • Settles-block template — C6 dry-run so the source_time field is not met cold on a busy reopen: at Tuesday's 06Z KRX settle I declare settles.KOSPI = { close: <jong-ga>, pct, prev_close: 6977.94, close_label: <native close token, frontmatter-only>, source: <allowlisted native host — a post-15:40 KST close-wrap, not an intraday article>, source_time: <the native close timestamp; MUST be ≥ 06:40Z / 15:40 KST — a pre-15:30 source on a native-labeled close is a C6 contradiction and HARD-FAILS from Fri 21 Aug> }. cb_level: OMIT by default. A level written as prev_close × 0.92 is derived from the very base it exists to confirm, so the breaker-math check (implied prev_close vs declared) can never fail — a zero-check wearing a pass, not verification. Declare cb_level ONLY if independently READ from KRX during the session, and then state which session base it belongs to (the KRX rolls the breaker onto the new base after the 15:30 close, so a post-close read belongs to the NEXT session, not the one being written up).
    • Base + constituents to compute off: KOSPI 6,977.94; Samsung ₩268,000; SK Hynix ₩1,593,000 (Friday true jong-ga) — re-anchor on a fresh raw-Naver curl at the settle (codes 005930 / 000660).
    • Won same-clock baseline: read Tuesday's onshore 15:30 fixing against the ~1,419 Friday onshore close (ONE baseline), NOT the ~1,413 offshore holiday drift — do not mix venues.
    • Oil-channel dispersion watchlist — the test IF oil makes a real move (else the channel stays UNADJUDICATED): Korea's oil-sensitive importers — airlines (Korean Air), shippers (HMM), utilities (KEPCO), petrochem (LG/Lotte Chem). Importers LAG the index + the won weakens same-clock = channel binds; importers hold + won holds = retire it. The index sign is not the test (chips dominate).

  • Falsifier / falsifier-v2 — NOT SCORED (Korea shut a 4th session, US pre-open): the semiconductor-switch stays CONFIRMED / ON from the 06Z Friday settle; re-tests Tuesday. The won-switch is NOT SCORED — ~1,413 offshore, oscillating in-band, a rendered holiday read; <10-won, DXY/CNH unconfirmed. Oil-channel: UNADJUDICATED, carried unchanged from 06Z — today's +0.6% is drift, not an oil MOVE, so it does NOT re-adjudicate; the read is not re-opened until oil actually moves (the level stays elevated, but an elevated level held is not a fresh test). Venue lens: offshore won the sole live read; a one-won drift is not a signal — carrying, not scoring. Scope/tense: a 4th-dark-day carry — carried base 6,977.94; the settled Korean read is Tuesday's session.

  • Changed since last (08-17 06Z → 12Z, still the 4th dark day): two small non-scoring drifts. (1) OIL ~$88.4 → ~$89 on the same US–Iran headline — a sub-1% drift, oil read stays UNADJUDICATED; (2) the WON ~1,414 → ~1,413, still in-band and not bending to the oil tick — oscillation; (3) the US has still not traded (12Z pre-open). Nothing scored; the setup stands; the reopen test is Tuesday.

Watch: 12Z STILL DOUBLY-DARK, the quietest window of the gap — KRX shut a 4th session (reopens Tuesday) AND the US still PRE-open (cash opens 13:30Z, after our cutoff), so nothing has settled since Friday and nothing scores; carried base 6,977.94, not re-reported. Honest read: almost nothing happened since 06Z — a short accurate carry, not a story · TWO SMALL NON-SCORING DRIFTS — oil firmed modestly to ~89.0 dollars (+0.6pct vs Fridays 88.52 settle) but well under a percent is DRIFT not the channel's trigger, so the oil read stays UNADJUDICATED (carried from 06Z, NOT re-adjudicated until oil actually moves); the won firmed a hair to ~1,413, still in its ~1,412-1,417 band and NOT bending to the oil tick (oscillation, NOT scored). The Tuesday setup STANDS · TUESDAY PREP STAGED while quiet — settles-block + C6 source_time template dry-run (cb_level OMITTED - a prev_close x 0.92 derivation cross-checks nothing; declare it only if independently read from KRX, with its session base), constituents to compute off (Samsung 268,000 / SK Hynix 1,593,000 raw-Naver), the won same-clock baseline (~1,419 Friday onshore, not the offshore drift), and the oil-importer dispersion watchlist. TESTS Tuesday — foreign 4th day or unwind, the won's onshore FIXING, the US Monday handoff (Scout), Sept 16 FOMC; semi-switch stays CONFIRMED / ON
