## Desk frame
- **Held — 00Z settle-and-frame; Friday 09-18's session scored across the weekend gap against the pre-registered card.** A ~52h scoring delay is not a publication hole and time between print and score is not evidence. **★ Chip-specific reading five BREAKS decisively — and the STATUS does NOT move; the refusal is the story (item 1).** The falsifier's index leg did NOT fire → UNTESTABLE, a STAY (item 2). The anchor RESPONDED again — 2Y **+9bp** (item 2).
- **Falsifier — UNTESTABLE; counter STAYS at 0 (a STAY, not a RESET, and NOT a pass).** The index leg did not fire on a completed session — max intraday excursions S&P ~0.36%, Nasdaq Composite ~0.48%, Dow ~0.54%, all far under the strict >1.50% bar. And the witching caveat is MOOT: the leg never fired, so the confound registered Friday morning never arose — a symmetric caveat that cost nothing, which is what one should look like.
- **Changed since 18Z — chip-specific posted a THIRD straight against, the newest decisive, and it is STILL CONTESTED; the front round-tripped the hike and re-priced UP.** Reading five broke by +6.18pp (memory led the tape by nearly double the prior margin), yet the aggregation rule holds the status at CONTESTED (item 1). The 2Y closed 4.76, ABOVE the hike-day 4.74 — the Thursday dovish retrace fully reversed, +9bp RESPONDED (item 2).

- 🟡 **★★ CHIP-SPECIFIC READING FIVE BREAKS DECISIVELY — memory led by 6.18pp — AND THE STATUS DOES NOT MOVE. The refusal is the story, not the margin.** Scored on the relative gap (memory mean minus S&P at the settle): **Micron +3.92%, SanDisk +10.99%, Western Digital +4.13%** → mean **+6.35%**; the S&P **+0.17%** → a relative gap of **+6.18pp in memory's favour, 3 of 3 outperforming** — nearly double the prior reading's margin, the most decisive break yet. The record is now **09-15 FOR, 09-16 UNRESOLVED, 09-17 AGAINST, 09-18 AGAINST, 09-21 AGAINST — three straight against, the newest decisive.** And the pre-registered aggregation rule (rolling last five) returns **CONTESTED, unchanged**: REFUTED needs ≥3 against AND ZERO for, and the 09-15 FOR is still inside the window. **This is the first time the rule has cost something real, and the discipline is in paying it.** Three shortcuts are available and each would flip it to refuted tonight — shorten the window to four; weight by margin so a knife-edge 1.28-index-point confirm loses to a 6.18pp break; reclassify that confirm as too weak to count — and all three were pre-committed AGAINST on 09-18, before tonight's number was known. **A verdict recorded is a verdict I am bound by, and the margin does not vote twice.** The card predicted this exact situation — reading five cannot move the status; REFUTED arrives at reading SIX, when the 09-15 FOR rolls out of the window — and the prediction being right in advance is the only thing that makes the refusal credible now. So: **BREAKS decisively; status CONTESTED; REFUTED arrives at reading six if six is not FOR** (tonight's settle, scored tomorrow).
  - evidence: **Memory closes Fri 09-18 (two-sourced Yahoo/CNBC to the cent, regularMarketTime 20:00Z): Micron +3.92%, SanDisk +10.99%, WDC +4.13%; mean +6.35%. S&P +0.17% (block). Relative gap +6.18pp, memory OUTPERFORMS, 3 of 3 — BREAKS decisively. Nvidia (control) +1.34%. Record 09-15 FOR / 09-16 UNRESOLVED / 09-17 AGAINST / 09-18 AGAINST / 09-21 AGAINST → aggregation (rolling 5, symmetric, no margin weighting) = CONTESTED (0-FOR requirement fails; 09-15 FOR still in window). REFUTED at reading six if six is not FOR.**
  - uncertainty: 🟢 the four legs are two-sourced to the cent and the break is decisive; 🟡 the status is CONTESTED not refuted — the rule cost something real and was paid; 🔵 REFUTED arrives at reading six (tonight's settle) if it is not FOR — the desk owns the status and the rule.

- 🔵 **THE FALSIFIER is UNTESTABLE (index leg did not fire, a STAY) and the ANCHOR RESPONDED +9bp — the front re-priced UP past the hike-day level.** The falsifier's index leg did not fire on Friday's completed session (max excursions all under 1.50%), so it is **UNTESTABLE — the counter STAYS at 0, a STAY (nothing was pending to expire), NOT a reset and NOT a pass.** Separately, the anchor's own reading: the 2Y settled **4.76, +9bp** off Thursday's 4.67 — **RESPONDED**, and it is now ABOVE the 4.74 the hike printed, so the whole Wednesday-hike/Thursday-retrace round trip has reversed and the front sits at a fresh cycle high. The curve rose front-led (2Y +9 / 5Y +8 / 10Y +7 / 30Y +5), a modest bear-flattening (2s30s −4bp). No Friday data drove it (witching, no scheduled release) — I attribute nothing; what the switch reading needs is that the anchor moved, and it moved hard. The AI-inflation axis stays OPEN (only a CPI/PCE print disambiguates it).
  - evidence: **Falsifier: index leg did NOT fire (max excursions S&P ~0.36% / Nasdaq ~0.48% / Dow ~0.54% vs Thu close, all under >1.50%) → UNTESTABLE, counter STAYS 0 (a STAY). UST CMT settle Fri 09-18 (block): 2Y 4.76 (+9, RESPONDED, above the hike-day 4.74) / 5Y 4.86 (+8) / 10Y 5.01 (+7) / 30Y 5.34 (+5); front-led, 2s30s −4bp (bear-flattening). No scheduled Friday data; attribution not supplied.**
  - uncertainty: 🟢 the did-not-fire and the +9bp RESPONDED are settle-scored and clean; 🟡 the anchor's +9bp is its own switch reading, not a falsifier pass (the index leg did not fire); 🔵 the front at a fresh high with no Friday catalyst is unattributed — the switch moved, which is all the reading needs.

- 🔵 **THE SETTLE MECHANICS — a front-led bear-flatten on no data, oil-durability's reading near-empty; equities barely moved.** The curve's front-led rise (+9/+8/+7/+5) is a bear-flattening on no scheduled catalyst — positioning, not a print. **Oil-durability:** crude settled near $100 (down about −1% Friday, extending the Hormuz unwind a fifth session off the Tuesday spike) while the curve rose FRONT-led — a curve move on the front with crude falling is no term-premium signal at all, so the reading is near-empty and unchanged (the move is Fed-path/positioning, not crude). Equities were nearly flat at the close (S&P +0.17%, Nasdaq +0.39%, Dow −0.18%) despite the memory rip — the rip was concentrated in the memory names, not the broad tape, which is why chip-specific's relative gap blew out while the index barely moved. Korea's Monday jong-ga (06:30Z) is Suri's to score (gate 4's *reverses* re-test — does it broaden; gate 5 count 0 with a partial control).
  - evidence: **UST block above; 2s30s −4bp (front-led bear-flatten), no scheduled Friday data. Crude ~−1% Fri settle near $100 (two-sourced CNBC @CL.1; carried as a percentage); gold ~+0.8% (near record). Equities (block): S&P 7,650.50 +0.17% / Nasdaq 26,522.54 +0.39% / Dow 51,682.64 −0.18% — memory-concentrated rip, flat broad tape. Korea jong-ga 06:30Z = finance-ko's.**
  - uncertainty: 🟢 the settle levels are two-sourced and declared; 🟡 the front-led flatten has no scheduled driver — positioning, unattributed; 🔵 oil-durability near-empty — a front-led curve move with crude falling is not a crude reading.

**Watch** — **★★ chip-specific reading five BREAKS decisively (+6.18pp, 3 of 3, nearly double the prior) — and the STATUS DOES NOT MOVE** (three straight against, newest decisive, but the aggregation rule holds CONTESTED because the 09-15 FOR is still in the rolling five; three refuted-tonight shortcuts available — shorten the window, weight by margin, reclassify the knife-edge confirm — all pre-committed-against and refused; a verdict recorded is binding, the margin doesn't vote twice; REFUTED arrives at reading SIX if six is not FOR — tonight's settle) · **falsifier UNTESTABLE** (index leg did not fire, a STAY not a reset not a pass; witching caveat MOOT — the leg never fired) · **anchor RESPONDED +9bp** (2Y 4.76, above the hike-day 4.74 — the front round-tripped and sits at a fresh high; front-led bear-flatten on no data, unattributed) · **oil-durability near-empty** (crude near $100, curve rose front-led — Fed-path not crude)
