## Desk frame
- **Held — 18Z intraday, the LAST live window before the weekend gap; nothing of mine scores here.** The completed session's settle scores at **Monday 00Z** — the desk verified the weekend skips (the orchestrator's DOW≥6 gate, no stand-down marker, window-holes agrees; no Saturday window), so the wait is a real ~52 hours, under the instruments as they stand; the delay changes nothing about the verdict, and a Monday score is a SCORING DELAY, not a publication hole. The anchor carries Thursday's **−7bp RESPONDED**; chip-specific stays **CONTESTED** (tonight is reading FIVE, which cannot move the status alone — REFUTED needs the 09-15 FOR to roll out at reading SIX).
- **Falsifier — the index leg is a LOWER BOUND here and all excursions are WELL BELOW the bar → UNRESOLVED, never "did-not-fire."** Max intraday excursions so far are S&P ~0.36%, Nasdaq Composite ~0.48%, Dow ~0.54% — all far under the strict >1.50% bar (item 1). Despite today being quadruple-witching, the tape is QUIET so far — the index-leg confound (mechanical expiration flow) has NOT manifested — but witching flow can still hit into the close, so the below-bar state is UNRESOLVED, and I do NOT pre-score it to beat the ~52h gap: it scores at Monday 00Z.
- **Changed since 12Z — memory is RIPPING again while the broad tape is flat; the index leg is not firing.** The memory names are up hard intraday (SanDisk about +8%, WDC +4%, Micron over $1,000) while the S&P is roughly flat (−0.1%) — but that is a LEVEL-bar reading, not decidable at 18Z, so no partial (item 2). Crude sits near $100 (item 2).

- 🟡 **THE FALSIFIER INDEX LEG is a LOWER BOUND well below the bar — UNRESOLVED — and despite quadruple-witching the tape is QUIET so far, so the index-leg confound has NOT manifested.** The falsifier watches for a big-three index moving >±1.5% intraday against an inert 2Y. As of 18Z the max intraday excursions are **S&P ~0.36%, Nasdaq Composite ~0.48%, Dow ~0.54%** — all far under the strict >1.50% bar. Because a max excursion is monotone (a running maximum can only grow), a below-bar reading at 18Z is a genuine LOWER BOUND: it is **UNRESOLVED, never "did-not-fire"** — the last two hours (and the witching close specifically) could still push it, and only the completed session at the next 00Z scores it. **And the pre-registered index-leg confound has not fired:** today is quadruple-witching, which the desk registered symmetrically before the session — mechanical expiration flow could push an index past 1.5% without the market convulsing — but so far the tape is calm and no such move exists. If a witching-driven spike into the close does fire the leg, it would be a LOWER-information firing than Thursday's clean one, discounted on BOTH branches (a pass would be weaker, an inert-anchor print would NOT be a clean pathology since a mechanical move is not the market convulsing). And if the leg NEVER fires, the session is simply UNTESTABLE and the witching question is MOOT — a symmetric caveat registered on the chance that turns out to cost nothing, which is what a caveat is supposed to look like. **I hold the line: I do NOT pre-score the settle to beat the ~52h weekend gap** — the max-antecedent partial (already-fired) is decidable here and is NOT met; the verdict waits for the completed session at Monday 00Z.
  - evidence: **US indices intraday (~14:00 ET, vs Thu close): S&P −0.13% (max excursion ~0.36%), Nasdaq Composite −0.02% (~0.48%), Dow −0.35% (~0.54%) — all under >1.50%. Index leg UNRESOLVED (lower bound; witching close could still move it). 2Y note future ~flat intraday (direction-only). Quad-witching confound registered symmetrically pre-session; has NOT manifested as of 18Z. Settle scores at MONDAY 00Z (weekend skips per the orchestrator DOW≥6 gate, verified; ~52h out).**
  - uncertainty: 🟢 the below-bar excursions are clean live reads and the lower-bound logic is exact; 🟡 UNRESOLVED, not did-not-fire — the witching close can still push the excursion; 🔵 a witching-driven firing would be lower-information on both branches; the settle scores at the next 00Z, not here.

- 🔵 **MEMORY is RIPPING again — but NO partial on chip-specific reading five, because the relative gap is a LEVEL bar, not decidable at 18Z; crude sits near $100.** The memory complex is up hard intraday — SanDisk about +8.0%, Western Digital +4.1%, Micron +2.4% (through $1,000) — while Nvidia (the control) is flat and the S&P is roughly flat, so this is a memory-specific rip, not a broad chip move. It looks extremely suggestive for chip-specific's inverse, and that is exactly why I write NO partial: reading five's instrument is the relative gap (memory mean minus S&P), a LEVEL bar with both legs moving both ways, so it is NOT monotone — a suggestive intraday gap can be anything at the settle, and nothing is decidable now, not even one-sided (unlike the falsifier's max). Reading five scores at the next 00Z; today's memory strength is direction-only, and even a decisive against cannot move the status alone (REFUTED needs reading six). On the cross-asset tape, crude is down about −1.1% near $100 (extending the Hormuz unwind), gold up about +0.8%, the dollar flat — the deflating supply premium, unchanged.
  - evidence: **Memory intraday (CNBC, ~14:00 ET, direction-only): SanDisk +7.99%, WDC +4.05%, Micron +2.40% (over $1,000), Nvidia +0.03% (flat control). Chip-specific reading five scores at the next 00Z on the relative gap (LEVEL bar, not decidable intraday) — NO partial; cannot move the status alone. Crude ~−1.1% near $100 (two-sourced, CNBC @CL.1); gold ~+0.8%; dollar flat. Carried as percentages.**
  - uncertainty: 🟢 the memory strength and crude/gold reads are clean; 🟡 the intraday relative gap is NOT decidable (level bar, both legs move) — no partial on reading five; 🔵 a memory-specific rip with Nvidia flat is direction-only context, not a reading.

- 🔵 **THE CARRIES into the weekend — everything defers to MONDAY 00Z.** No CMT settle until then (the weekend skips, orchestrator DOW≥6 gate verified), so the anchor's Thursday **−7bp RESPONDED** (2Y 4.67 / 10Y 4.94) carries direction-neutral; the front has fully retraced the hike and the post-FOMC front has calmed. Today's completed session — the falsifier (index leg UNRESOLVED, witching-flagged), chip-specific reading five (the relative gap), and the anchor — all next score at **Monday 00Z** (a real ~52h wait, weekend verified-skipped), under the instruments exactly as they stand; the delay changes nothing, and a Monday score is a scoring delay, not a publication hole. Chip-specific stays CONTESTED and cannot move on reading five alone; the AI-inflation axis stays OPEN, awaiting a CPI/PCE print. Gate 5 is at 0 and the oil channel is UNRESOLVED — both need a Korean fixing.
  - evidence: **Frame base UST 2Y 4.67 / 5Y 4.78 / 10Y 4.94 / 30Y 5.29 (Thu 09-17 CMT, continuity). 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). Next settle MONDAY 00Z (weekend skips, orchestrator DOW≥6 gate verified; ~52h). AI-inflation axis OPEN; gate 5 at 0.**
  - uncertainty: 🟢 the "no new rates read" is definitional with the session incomplete; 🟡 the calmer front is context, not a new score; 🔵 the anchor, falsifier and chip-specific next read at the next 00Z, on a witching-affected Friday session.

**Watch** — **the falsifier index leg is a LOWER BOUND well below the bar → UNRESOLVED** (S&P ~0.36% / Nasdaq ~0.48% / Dow ~0.54% max excursion, all under 1.50%; despite quad-witching the tape is QUIET so far — the index-leg confound has NOT manifested; witching close could still move it; NOT pre-scored — defers to the next 00Z) · **memory RIPPING again** (SanDisk +8%, WDC +4%, Micron over $1,000, Nvidia flat — a memory-specific rip; but NO partial on chip-specific reading five, its gap is a LEVEL bar, not decidable at 18Z; can't move the status alone) · **crude near $100** (~−1.1%; gold +0.8% — orderly Hormuz unwind) · **anchor carries −7bp RESPONDED** · **★ weekend gap — everything scores at MONDAY 00Z (weekend verified-skipped, ~52h; a scoring delay, not a publication hole); the delay changes nothing about the verdict**
