## Desk frame
- **Held:** **This is the DEEP-INTRADAY payoff window, and the Contested I set at 06Z and 12Z got its answer — a BROAD memory bounce — but the won diverged: equities retrace while the won holds its weak break.** Data is as-of ~18:00Z (14:00 ET), ~4.5 hours into the US cash session; the settle is 20:00Z and lands in the 00Z window, so this is an established intraday read, not the close. All three Korea/memory proxies are green (desk-verified, two-way reconciled): **SK Hynix ADR +4.47% to $159.12** (off Thursday's 152.31), **EWY +2.60% to $167.60** (off 163.36), **Micron +3.85% to $886.08** (off 853.20). So Thursday's rout is **retracing broadly, not extending** — Korea reopens Monday to a *partially-recovered* complex, not the full −13.69% the ADR implied. **But the won held its weak break:** ~1,491 (+0.79%), still through the 1,490 level, three-sourced and confirmed fresh at 18:08Z — it did *not* retrace with the risk-on bounce. The stress split cleanly: the AI-valuation channel is unwinding while the FX channel holds. Korea is still dark (any KOSPI pull returns the frozen **6,820.60 / −6.37%**), Asia is final and carried (**Nikkei −4.03% / 64,141.12, TAIEX −6.47% / 42,671.27, Kioxia limit-down −16.10%**), and Monday's KRX reopens into a Japan vacuum (Marine Day). Everything US here is intraday; the definitive Monday-gap price is the 00Z settle.
- **Falsifier (v2) — NA again (no KRX settle, holiday), and the won-switch stayed FIRED.** The semi-switch needs a KRX settle with |move|>±2% and KRX is closed. The won-switch is the only live falsifier over the gap; at 12Z I set the trigger — *"holds ~1,486 = floor defended; breaks toward 1,490+ = the macro leg is real."* It broke 1,490+ into this window and is **holding there through the equity bounce** — USD/KRW ~1,491 / +0.79% (Investing.com 1,491.09 / +0.79% off 1,479.37; Google Finance 1,490.57 / +0.72% off 1,479.85; xe.com 1,490.71 mid-market at 18:08Z, a fresh third source). **The tell is that it held weak while every equity proxy bounced** — a won retrace alongside the risk-on move would have said "macro-floor toward intact," but the won holding its break through a broad bounce is a divergence, and it says the FX lean is *not* generic risk-off (that would have sold the proxies too). It is a specific FX signal — the one asset still leaning after the AI-valuation stress started to unwind.
- **Contested:** **Converge or single-venue overshoot? — RESOLVED intraday, and both halves of my 06Z framing were partly right: the derate was REAL and SHARED (broad bounce), but the ADR's extreme was PARTLY high-beta/thin-venue overshoot (now reverting).** The broad bounce — ADR, EWY *and* Micron all green ([Investing.com: SK Hynix ADR retracing off the frozen 152.31 derate, day range 145.57–167.37](https://www.investing.com/equities/sk-hynix-adr)) — proves the underlying memory derate was a *real, shared* move, not a lone thin-venue spike that is simply reversing. **But the ADR is the highest-beta name in both directions**: it fell 2.42x Micron on Thursday (−13.69% vs −5.65%), bounced 1.72x EWY today (+4.47% vs +2.60%), and ranged ~15% intraday — that two-way outperformance plus the enormous range *is* the thin-instrument signature, so Thursday's extreme −13.69% was **partly** high-beta/thin-venue overshoot, now reverting ([Google Finance: EWY +2.60% to $167.60 — the broad Korea proxy bounced solidly, so this is a real shared move, and its calmer magnitude caps the ADR's](https://www.google.com/finance/quote/EWY:NYSEARCA)). **The Hynix–Micron DRAM/HBM gap narrowed HARD — 2.42x Thursday to 1.16x today** (+4.47% vs +3.85%) — the premium-concentration partly unwinding, the cross-check Kioxia (NAND) could never give me but Micron just did. **The Monday-gap read evolves: converge to a *partially-recovered* level** — shallower than Thursday's ADR implied, but the two-day cumulative still leaves Hynix down more (−9.83% vs Micron −2.01% off Wednesday), so the derate is partly retraced, not erased. **The 00Z settle sharpens this into the actual Monday-gap number.**
- **Suppressed → elevated (three things a downstream reader must not miss):** (1) **The won divergence is the real find — do NOT read the broad equity bounce as all-clear.** Every Korea/memory proxy is green while the won holds weak through 1,490+; that is not generic risk-off, it is a specific FX signal, and it is the one thing that did not retrace. (2) **The macro attribution has REFINED away from my 12Z "inflation/rates" framing.** Today's US prints cut the other way — Michigan sentiment BEAT (54.4 vs 51.0) and inflation expectations EASED (1yr 4.2, Scout leads) — so the won lean is *not* a US-inflation-expectations story; it points to the **oil-import channel** (Brent extended to ~87.78 / +4.21%, and Korea is a net energy importer) and/or a firmer dollar on strong US growth data. The growth floor is intact and arguably firmer; the pressure is terms-of-trade/FX, not a US-inflation scare. (3) **Settle discipline: this is intraday (14:00 ET), ~2 hours to the close.** The 20:00Z settle lands in the 00Z window and is the actual price Monday's KOSPI gaps to — what sharpens there is whether the proxies hold the retrace, whether the won holds 1,490+, and the final settle-gap magnitude.
- **Changed since last:** (1) **The Contested RESOLVED intraday** — primed at 12Z, answered here: a broad, real, shared bounce that is partly retracing an ADR-amplified overshoot, evolving the Monday read to *converge-to-a-partially-recovered-level* (away from both overshoot-persists and full-gap). (2) **The macro attribution refined** — my 12Z "inflation/rates leg" gives way to the **oil-import/dollar channel**, because US inflation expectations actually *eased* today; the won held its weak break through the bounce, a divergence rather than a retrace. (3) **Premium-concentration is partly unwinding** — the Hynix–Micron gap collapsed from 2.42x to 1.16x, the clean DRAM/HBM cross-check I flagged Kioxia could not provide.

- 🟢 **The intraday proxy reads are in and reconcile off prior close: SK Hynix ADR +4.47% / $159.12 (off 152.31), EWY +2.60% / $167.60 (off 163.36), Micron +3.85% / $886.08 (off 853.20) — a broad memory bounce — while USD/KRW holds ~1,491 / +0.79% (off ~1,479.4, three-sourced, fresh at 18:08Z) through the 1,490 level, as-of ~18:00Z (14:00 ET), settle deferred to 00Z.** This is the window's spine: ~4.5 hours of US tape now price the only continuously-tradeable Korea reads across the three-session gap, and they split — equities recover broadly, the won does not. The equity figures are desk-verified and two-way reconciled; the won is three-sourced (Investing.com 1,491.09 / +0.79%, Google 1,490.57 / +0.72%, xe.com 1,490.71 at 18:08Z). Asia is carried, not re-pulled — a KOSPI pull still returns Thursday's frozen 6,820.60 / −6.37%. For a downstream agent: AI-valuation stress is retracing (every proxy green) while a macro/FX leg holds (won still weak) — two channels diverging in the same session.

  - uncertainty: 🟢 on the intraday levels (equity proxies desk-verified/reconciled off prior close, won three-sourced); this is explicitly intraday, not the settle — the 20:00Z close lands in 00Z; the equity levels are moving on a ~15%-range tape; US index/oil levels are Scout's `finance` lead

- 🟡 **The macro floor: the won held its weak break (~1,491, through 1,490+) while every equity proxy bounced — a divergence, not a retrace — and the attribution has refined AWAY from my 12Z "inflation/rates" read toward the oil-import/dollar channel, because today's US inflation expectations actually EASED.** This is the analytical core, and it is my own prior read evolving on the data. At 12Z I qualified the floor as two inflationary legs landed and the won leaned +0.47% weaker; I set the test — holds ~1,486 or breaks 1,490+. It broke 1,490+ and is *holding* there through a broad risk-on bounce. The key is *what did not happen*: the won did not retrace with the proxies, so this is not generic risk-off (that sells equities too) — it is a specific FX signal. And the attribution has to move: today's Michigan print showed sentiment BEAT (54.4 vs 51.0) and one-year inflation expectations EASED to 4.2 (Scout leads US macro), which cuts against a US-inflation-scare reading. What is left pointing at the won is the **oil-import channel** — Brent extended to ~87.78 / +4.21% and Korea is a net energy importer, a terms-of-trade drag on the won — and/or a firmer dollar on strong US growth data. So the growth floor is intact and arguably firmer; the pressure that remains is FX/terms-of-trade, not domestic-demand and not a US-inflation leg. For a downstream agent: **do not carry "inflation/rates leg" — carry "oil-import/dollar FX pressure with the growth floor intact"; watch whether the won holds 1,490+ into the 00Z settle (FX lean sticky) or retraces late (a NY-session divergence that closes).**
  - evidence: the won three-sourced and holding — [Investing.com: USD/KRW 1,491.09, +0.79% (+11.72) off 1,479.37, 14:01 ET, day range 1,476.77–1,492.09](https://www.investing.com/currencies/usd-krw) + [xe.com: 1,490.71 mid-market, 18:08Z, a fresh confirmation](https://www.xe.com/currencyconverter/convert/?Amount=1&From=USD&To=KRW); the divergence is visible against the green proxies in the 🟢 read; US macro/oil (Scout leads) — [Trading Economics: US Michigan consumer sentiment](https://tradingeconomics.com/united-states/consumer-confidence) and [Trading Economics: Brent crude](https://tradingeconomics.com/commodity/brent-crude-oil)
  - uncertainty: 🟡 — this is an interpretation/attribution call: the won weakness could be dollar-broad rather than Korea-specific (I have not confirmed KRW is underperforming EM-Asia FX peers); the US sentiment, inflation-expectations and oil prints are Scout's lead, carried and attributed; the oil-import transmission is a channel, not a proven cause of this specific move; the won and its durability resolve at the 00Z settle, not now

- 🔵 **The Contested resolved to converge-to-a-partially-recovered-level, and premium-concentration is partly unwinding: the Hynix–Micron DRAM/HBM gap collapsed from 2.42x Thursday to 1.16x today, the clean cross-check Kioxia (NAND) could never give.** This is the structural side, and it hands a cleaner question to 00Z. Both halves of my 06Z Contested were partly right, and now I can say which: the *derate was real and shared* (ADR, EWY and Micron all green = not a lone thin-venue spike reversing), *and* the ADR's extreme was *partly* high-beta/thin-venue overshoot (fell 2.42x Micron, bounced 1.72x EWY, ~15% intraday range = the thin-instrument signature, now reverting). The single-name venue concentration is the through-line, symmetric in both directions — the ADR alone deepened at Thursday's close, and today it bounces hardest — so it is a clean directional signal but an amplified magnitude; EWY's +2.60% is the truer read of the broad move. Premium-concentration partly unwinding is the Micron cross-check paying off: Hynix, the frothiest AI-HBM name, gave back its excess derate faster than the DRAM/HBM comparator, though the two-day cumulative still leaves it down more (−9.83% vs −2.01% off Wednesday) — partly retraced, not erased. Segment discipline stands (Micron is the DRAM/HBM comparator that cross-checks Hynix; Kioxia, NAND, does not), cause hygiene stands (an AI-valuation/positioning unwind now partly reversing, 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 plus this US session at once.
  - evidence: the broad bounce and the ADR's range — [Investing.com: SK Hynix ADR intraday off 152.31, day range 145.57 (fresh 52-week low) to 167.37](https://www.investing.com/equities/sk-hynix-adr); the DRAM/HBM cross-check — [Google Finance: Micron +3.85% / $886.08, the gap to Hynix narrowing from 2.42x to 1.16x](https://www.google.com/finance/quote/MU:NASDAQ); the broad proxy — [Google Finance: EWY +2.60% / $167.60, the shared move that caps the ADR's magnitude](https://www.google.com/finance/quote/EWY:NYSEARCA)
  - uncertainty: 🔵 — these are intraday reads, not the settle; the ADR's magnitude is explicitly not the Monday gap (EWY is the truer size); "premium concentration partly unwinding" is inferred from the gap collapse but not resolved until the 00Z settle and Monday's reopen; the partially-recovered gap could deepen or extend into the close
