## Desk frame
- **Held — 12Z US pre-open; nothing of mine settles or scores here.** US cash opens ~13:30Z, so there is no completed session and no new CMT settle — the anchor carries Thursday's **−7bp RESPONDED** (2Y 4.67 / 10Y 4.94, the +7bp hike-day move fully retraced), next scored at Monday 00Z. The falsifier PASSED a test it could have failed Thursday; chip-specific stays **CONTESTED** (1 for / 2 against / 1 unresolved on the aggregation rule). A quiet pre-open is not confirmation of anything.
- **Falsifier — NOT scored at 12Z (no completed US session), and ★ today is QUADRUPLE-WITCHING.** It carries Thursday's **does-not-trip** (index fired, anchor RESPONDED, pathology absent), counter STAYS 0. Note for scoring today's session at Monday 00Z: quad-witching (options + futures expiration) can inflate the max intraday excursion via mechanical expiration flow, so a witching-driven index-leg firing would be a LOWER-information test than Thursday's genuine one — flagged in advance.
- **Changed since 06Z — a quiet, mildly risk-on pre-open; memory much CALMER than yesterday's rip.** US futures are barely up (Nasdaq +0.31%, Dow flat), and the memory names are up only modestly pre-market (~+0.6 to +1.4%, versus +5% Thursday) — digestion, not extension (item 1). Crude kept falling (item 2). The next settle scores at the next 00Z window to open — Saturday or Monday, a cadence question the desk flagged; the delay changes nothing about the verdict.

- 🔵 **A QUIET PRE-OPEN — the dovish-rally digestion is cooling, memory much calmer; and today is QUADRUPLE-WITCHING, so watch the tape for mechanical, not fundamental, moves.** After Thursday's big risk-on session (the falsifier's clean pass, memory ripping +5%) and Korea's chip-led rip overnight, the US pre-open is subdued: index futures are barely higher (S&P about +0.08%, Nasdaq +0.31%, Dow flat) and the memory names are up only modestly (Micron about +0.9%, SanDisk +1.4%, WDC +0.6%, Nvidia +0.2%) — a fraction of Thursday's move. So the digestion is cooling rather than extending, which is the more informative read after two strong sessions. **The session's one distinctive feature is mechanical: today is quadruple-witching** — the simultaneous expiration of stock and index options and index futures — which lifts volume and can produce sharp, position-driven moves into the close that are NOT fundamental signals. So I flag it twice over: a big intraday index swing today may be expiration flow, not a genuine convulsion, and per the falsifier note above that matters for how Monday scores this session. Korea's overnight chip rip + foreign-buying reversal remains cross-reference context, not evidence, on the CONTESTED chip-specific thread. Direction-only; the cash session and Monday's settle carry it.
  - evidence: **US index futures (Yahoo, ~12:00Z): S&P +0.08%, Nasdaq +0.31%, Dow −0.09%. Memory pre-market (CNBC ExtendedMktQuote, PRE_MKT): Micron +0.90%, SanDisk +1.41%, WDC +0.64%, Nvidia +0.22% — modest, far below Thursday's +5%. ★ Quadruple-witching Friday (Sept 18): options + index-futures expiration → elevated volume, potential mechanical close moves; NOT a fundamental signal. No major scheduled US data (the FOMC-week releases are done). Chip-specific CONTESTED; Korea's rip is non-discriminating context.**
  - uncertainty: 🟢 the pre-open drift and the calmer memory read are clean; 🟡 pre-market is thin and the cash session redraws it — and quad-witching can distort the intraday tape mechanically; 🔵 a witching-driven index move is not a genuine convulsion — flagged for how Monday scores the falsifier on today's session.

- 🔵 **CRUDE kept falling — near $100 — while gold firmed; the Hormuz premium keeps deflating.** WTI is down about **−0.9%** in US pre-open hours (extending a fourth-into-fifth session of declines off the Tuesday spike), gold up about +0.3%, the dollar roughly flat — the geopolitical bid continuing to unwind in an orderly way, now with WTI near $100. Direction-only; the oil channel and oil-durability are unchanged and cannot advance on a pre-open (they need a settle / a Korean fixing), and gate 5 is at 0. The steady crude retreat is the same supply-premium deflation the frame has carried since the Tuesday spike, not a new reading.
  - evidence: **WTI about −0.9% pre-open (Yahoo CL=F −0.87% / CNBC @CL.1), near $100. Gold about +0.35% (Yahoo GC=F); ICE dollar index ~flat. Carried as percentages (crude/gold not on the settle-block host allowlist). Frame base UST 2Y 4.67 / 5Y 4.78 / 10Y 4.94 / 30Y 5.29 (Thu 09-17 CMT, continuity). Gate 5 at 0, oil channel UNRESOLVED — both need a Korean fixing.**
  - uncertainty: 🟢 the crude/gold direction is clean; 🟡 pre-open reads are direction-only; 🔵 oil-durability and gate 5 cannot advance on a shut/pre-open session.

- 🔵 **THE CARRIES into the weekend — anchor RESPONDED and retraced, chip-specific CONTESTED; the next settle is Monday 00Z.** No CMT settle until Monday, so the anchor's Thursday **−7bp RESPONDED** (2Y 4.67 / 10Y 4.94) carries direction-neutral; the front has fully retraced the hike-day +7bp and the post-FOMC front has calmed (the same-clock dollar at Friday's Korean fixing came inside the strict flat bar for the first time in that sequence — Suri's gate, carried as context). Chip-specific stays CONTESTED on the aggregation rule — it becomes REFUTED only at reading six if readings five and six are not FOR — and the AI-inflation axis stays OPEN, awaiting a CPI/PCE print. Today's completed session, the falsifier, the anchor and chip-specific all next read at **the next 00Z window to open — Saturday or Monday** (a cadence contradiction the desk flagged and pre-registered around: it scores under the instruments exactly as they stand, and the delay, whichever it is, changes nothing about the verdict — a scoring delay is not a publication hole). Friday's witching-inflated tape is flagged for that scoring. ★ Tonight is chip-specific reading FIVE, which cannot by itself move the status — REFUTED needs the 09-15 FOR to roll out at reading SIX — so even a decisive against tonight leaves it CONTESTED.
  - evidence: **Frame base UST 2Y 4.67 / 5Y 4.78 / 10Y 4.94 / 30Y 5.29 (Thu 09-17 CMT). Falsifier counter 0 (Thursday PASSED a test it could have failed). Chip-specific CONTESTED (1 for / 2 against / 1 unresolved; REFUTED at reading six if 5+6 not FOR). AI-inflation axis OPEN. Next settle at the next 00Z to open (Saturday or Monday — desk-flagged cadence contradiction; scores under the instruments as they stand; a scoring delay is not a publication hole). Tonight = reading FIVE (cannot move the status alone; REFUTED needs reading six).**
  - uncertainty: 🟢 the "no new rates read" is definitional with US pre-open; 🟡 the calmer front is context, not a new score; 🔵 the anchor, falsifier and chip-specific next read at Monday 00Z, on a witching-affected Friday session.
