## Desk frame
- **Held:** **This is a PRE-OPEN SETUP window by design — Korea dark for a second read (Constitution Day), Asia final and carried, and the US session Monday's KOSPI will gap to has NOT happened yet.** Data is as-of ~12:00Z: US cash opens 13:30Z (90 minutes past the label) and settles 20:00Z, which lands in the 18Z and 00Z windows — so everything US here is **intraday by construction and the settle is deferred**, and the marquee event (how the Korea proxies trade the whole US session) is deferred *on purpose*, not missed. The window's real job is to **frame the last live pre-reopen test and name what would resolve it.** Asia is done and carried verbatim: **Nikkei −4.03% / 64,141.12** (15:30 Itayose settle), **TAIEX −6.47% / 42,671.27**, **TSMC Taipei ~−7.29%**, **Kioxia limit-down −16.10%** (a mechanical floor). KRX is shut, so any KOSPI pull still returns **Thursday's 6,820.60 / −6.37%** — absent, not lagging. Across BOTH holidays (Korea Friday, Japan Monday) the only continuous Korea reads are **US-listed/offshore** — the Hynix ADR, EWY, the US memory tape, and the near-24h won. **The change this window is the macro floor:** at 06Z I called it intact and the stress "AI-valuation-concentrated, not Korea-macro." Two live inflationary legs now run against that in the same session — **US import prices came in HOT (+0.3% vs −0.7% forecast, a 1.0pp miss to the inflationary side; Scout leads US macro) and Brent broke UP ~+2% to ~86 on a sixth straight night of US strikes on Iran** — and the **won has already leaned ~+0.45% weaker to ~1,486** (off ~1,479.4), near the weak end of its day range. The floor is not broken, but its character has shifted: the *growth* floor holds (housing starts beat 1.427M vs 1.310M; Thursday claims 208k), while a fresh *inflation/rates* leg is now pressuring the won — the one thing the AI-valuation story does not cover.
- **Falsifier (v2) — NA again (no KRX settle, holiday), and the proxy test is DEFERRED BY DESIGN, not run.** The semi-switch needs a KRX settle with |move|>±2%; KRX is closed. Reading the Hynix ADR / EWY / Micron 35 minutes after a 13:30Z open would be the **weakest** version of my own Contested test — it turns on how the proxies behave across the *whole* US session (18Z gives ~4.5 hours, 00Z gives the settle Monday actually gaps to), so I defer it there rather than over-read a sliver. **The won-switch is the only live switch over the gap** — and it moved: **~+0.45% weaker (~1,486, off ~1,479.4), no hard trigger, but directionally the first macro lean** rather than the flat print of 06Z. That is the falsifiable thing this window can actually observe, and it leaned slightly against my own "not macro" read.
- **Contested:** **Is Monday's KOSPI reopen a real gap that CONVERGES to the proxies, or a single-venue OVERSHOOT into a Japan vacuum? — unchanged, and explicitly NOT resolvable this window.** It resolves across the full US session and into Monday, so the honest contribution now is to state **what would answer it**: does the Hynix ADR extend Thursday's −13.69% or stabilise/retrace (a thin pre-market bounce to +1.27% is a flag, not the answer) ([Google Finance: SK Hynix ADR $152.31 Thursday close, +1.27% pre-market at $154.25, 8:02am ET — pre-open and thin, deferred to the session](https://www.google.com/finance/quote/SKHY:NASDAQ)); does **EWY track the ADR or diverge** (a divergence between the two Korea proxies is itself a read on whether the ADR is a clean signal or a thin instrument); and does the **Hynix-vs-Micron 2.4x DRAM/HBM gap narrow in NY** (Micron is the DRAM/HBM comparator that DOES cross-check Hynix; Kioxia, being NAND, does not), which would test my premium-concentration read directly ([Investing.com: SK Hynix ADR −13.69% to $152.31 vs Micron −5.65%, the same DRAM/HBM segment, a 2.4x gap a broad move does not explain](https://www.investing.com/equities/sk-hynix-adr)). For a downstream agent: **the question is primed; 18Z and 00Z hold the answer.**
- **Suppressed → elevated (three things a downstream reader must not miss):** (1) **Pre-open discipline — do NOT read a thin pre-market tick as the test.** The ADR's path (an after-hours leak to ~150.29, then a pre-market bounce to 154.25) is a *flag*, not a level; the session is the test and it is deferred to 18Z/00Z. (2) **The macro floor is now a LIVE question, not a settled "intact."** Two inflationary legs (import prices hot, Brent +2%) plus a won leaning ~+0.45% weaker mean the "stress is AI-concentrated, not macro" read has acquired a nascent macro component — watch the won, not a nonexistent KOSPI print. (3) **Segment discipline holds:** the comparator to watch in NY is **Micron (DRAM/HBM)**, not Kioxia (NAND); the 2.4x Hynix-vs-Micron gap is the open question, and only a DRAM/HBM name can close it.
- **Changed since last:** (1) **Window type flipped** — 06Z was a settle window (wait for the close); 12Z is a **pre-open setup** (the marquee US session is deferred by design to 18Z/00Z, its natural homes). The rule is not "wait for the marquee event" — it is "wait only when the event would be orphaned," and the US session is not orphaned. (2) **The macro floor, called "intact" at 06Z, now faces two inflationary legs and a won that has leaned ~+0.45% weaker** — I qualify it, not abandon it: growth floor holds, a fresh inflation/rates leg is pressuring the won. (3) The Contested is **unchanged but now explicitly primed with its resolvers** (ADR extend/stabilise, EWY track/diverge, Hynix-Micron gap narrow/hold) for the downstream windows to answer.

- 🟢 **This is a pre-open setup: Korea dark a second read (Constitution Day), Asia final and carried (Nikkei −4.03%/64,141.12, TAIEX −6.47%/42,671.27, TSMC ~−7.29%, Kioxia limit-down −16.10%), and the US session Monday's KOSPI will gap to has not happened yet — US opens 13:30Z, settles 20:00Z (18Z/00Z), so everything US here is intraday and the settle is deferred.** This is the window's spine and its honest limit. On the day KRX went dark a second time, the region's repricing is already on the tape (Friday's Asian closes, carried verbatim from the 06Z settle) and cannot be re-opened by a lagging wire; a KOSPI pull still returns Thursday's frozen 6,820.60/−6.37%. From Thursday's US close through Monday's Seoul open, the only continuously-tradeable Korea reads are US-listed/offshore — the Hynix ADR and EWY on the US session, the US memory tape, and the near-24h won — because the two big Asian cash venues never overlap across the gap (Korea dark Friday, Japan dark Monday for Marine Day). For a downstream agent: Monday's KOSPI will gap to whatever this US session and the weekend price in; this window sets the board, the next two read the move.
  - evidence: Asia carried, not re-pulled — [Nikkei marketdata: Nikkei 225 −4.03% at 64,141.12, July 17 15:30 closing auction, the authoritative index print](https://www.nikkei.com/marketdata/quote/NK225/); [Focus Taiwan/CNA: TAIEX ended −6.47% at 42,671.27, July 17](https://focustaiwan.tw/business/202607170009); Japan dark Monday [TradingHours: JPX/Tokyo Stock Exchange closed Monday July 20 2026 for Marine Day](https://www.tradinghours.com/markets/jpx)
  - uncertainty: 🟢 on the window structure and the carried Asian closes (settled, reconciled at 06Z); the US session is deferred by design, not uncertain; US index/oil levels are Scout's `finance` lead

- 🟡 **The macro floor is now a live question, run against my own 06Z lead: two inflationary legs landed in this session — US import prices HOT (+0.3% vs −0.7% forecast, a 1.0pp inflationary miss) and Brent ~+2% to ~86 on a sixth night of Iran strikes — and the won has leaned ~+0.45% weaker to ~1,486, so the "stress is AI-valuation-concentrated, not Korea-macro" read has acquired a nascent MACRO component I am qualifying, not carrying blind.** This is the analytical core of this window. At 06Z the won held flat (~1,480, +0.06%) while froth pinned limit-down, and I read the stress as sector-concentrated with the macro floor intact. That read now takes a live test: US macro (Scout's lead) turned inflationary this session — import prices missed 1.0pp to the hot side and Brent is up ~13% on the week (third weekly gain) on the Iran strikes — which points to a firmer dollar and higher-for-longer US rates, and Korea is a net energy importer whose won is EM-Asia FX. The won responded: ~+0.45% weaker to ~1,486 (off ~1,479.4), near the weak end of its day range — small, but directional and toward weakness exactly as the inflationary legs hit. The precise read: the **growth** floor still holds (housing starts beat 1.427M vs 1.310M; Thursday claims 208k, lowest in 2+ months — this is not a growth scare), but a fresh **inflation/rates** leg is now pressuring the won, and that is a macro channel the AI-valuation-unwind story does not cover. For a downstream agent: **do not carry "the floor is intact, it is all AI-valuation" unexamined — watch the won as the live macro tell into 18Z/00Z; if it holds ~1,486 through NY liquidity the floor is defended by a real stress test, if it breaks toward 1,490+ the macro leg is real.**
  - evidence: won two-sourced and reconciled — [Investing.com: USD/KRW 1,486.66, +0.49% (+7.29) off prev 1,479.37, real-time 08:37 ET, day range 1,476.77–1,488.53](https://www.investing.com/currencies/usd-krw) + [Google Finance: USD/KRW 1,486.14, +0.425% off prev 1,479.85, 12:37 UTC](https://www.google.com/finance/quote/USD-KRW); US macro (Scout leads) — [Trading Economics: US import prices, monthly print](https://tradingeconomics.com/united-states/import-prices) and [Trading Economics: US housing starts](https://tradingeconomics.com/united-states/housing-starts); oil [Trading Economics: Brent crude](https://tradingeconomics.com/commodity/brent-crude-oil)
  - uncertainty: 🟡 — this is an interpretation/attribution call: ~+0.45% is a modest lean, not a break, and could be dollar-broad rather than Korea-specific; the US macro prints and oil are Scout's lead, carried and attributed, not independently my figures of record; the transmission (US inflation → firmer USD/rates → won weakness) is a channel, not a proven cause of this specific tick; the resolution is at 18Z/00Z, not now

- 🔵 **The Contested is primed, not resolved — this window names what would answer it and hands the read to 18Z/00Z: does the Hynix ADR extend or stabilise, does EWY track or diverge, does the Hynix-vs-Micron 2.4x DRAM/HBM gap narrow in NY?** This is the steady, structural side. The only live Korea reads over the gap trade in this US session, so the next two windows — not this one — hold the resolution of converge-vs-overshoot. What to watch, precisely: (a) the **Hynix ADR** — a pre-market bounce to +1.27% (154.25, off the 152.31 Thursday close) after an after-hours leak to ~150.29 is a *flag not a level*; whether it stabilises or re-extends across the session is the converge-vs-overshoot tell; (b) **EWY vs the ADR** — if the broad Korea proxy tracks the ADR, the ADR is a clean signal; if it diverges, the ADR is a thin single-name instrument and Monday's gap is less predictable; (c) **Micron** as the DRAM/HBM comparator — if the Hynix-vs-Micron gap narrows in NY, my premium-concentration read (Hynix the frothiest AI-HBM name) gets a real test; Kioxia (NAND) cannot close it. Segment discipline stands, cause hygiene stands (this is an AI-valuation/positioning unwind, not "tighter US chip rules" — 2026 export policy has been loosening). BOK 2.75% is the domestic overhang; Monday's KOSPI reopens into a Japan vacuum, absorbing three sessions and this US session at once.
