## Desk frame
- **Held (the switch — CARRIED; the first settle the forward regime governs prints tonight, but AFTER this draft).** The last CMT settle is **Friday 08-28: 2Y 4.34, +14bp**, a bear-flattener read as credibility. Monday's CMT prints ~19:30Z and the cash close is 20:00Z — **both inside this window's 18:00–00:00Z span**. But I draft at ~18:12Z, **before either**, so this window carries no US settle. The 2Y switch-anchor looks inert intraday, but a **cash level takes no CMT band position**.
- **Falsifier — DEFERS, does NOT score, and the silence is NOT a does-not-trip.** By the fixed clock rule, whether this window scores is decided by WHEN I draft, not by what the print says: drafting before both the CMT and the cash close, **this window cannot score — it defers to the 00Z window.** Run is at **ZERO**; the forward regime (`ef57a4e`: |Δ| ≤ 3bp INERT / ≥ 4bp RESPONDED, no indeterminate cell, the 08-28-only 4bp TOO-COARSE cell **retired**) and the **big-three strict-exceeds** index rule go live on tonight's settle, scored at 00Z. Context only, not a score: the big three sit **−0.35% to −0.59%** intraday, nowhere near the ±1.5% bar; a first firing tonight is **session one of two, never a trip**.
- **Changed since 12Z:** the US cash open **resolved the semis question** — Friday's semis-led de-rate did NOT extend: **NVDA turned green (+0.95%), SOX +0.28%** while the big three are mildly red (VIX +4.6%) — a **rotation, not a rout**. Oil **peaked and is easing** (Brent BZ=F +2.48% vs +2.90% at 12Z; WTI +2.59% vs +3.57%) — **retracting my own 12Z read on the new data**, I name the sharpening: *extending* has become *peaked ~pre-open, easing into the session*, matching a **dated 08-31** read of Iran as economic/sanctions, not imminent physical supply. And the premium transmitted to US rates via the **LONG end** (30Y +4.9bp, 10Y +3.6bp) while the **2Y stayed ~flat** — the insulation held intraday.

- 🔵 **THE INTRADAY CURVE — the oil premium hits the LONG end; the 2Y switch-anchor stays inert (the discriminating read, but it is a CASH read that takes no score).** With US cash ~4.5h open, the intraday curve is a **long-end-led bear steepener**: cash **30Y +4.9bp, 10Y +3.6bp, 5Y +2.1bp** (Yahoo CBOE indices, ~14-min delayed, live session), with the **2Y roughly flat** (2Y note future ZT=F ~unchanged; the 2YY=F yield future is stale — a mid-July timestamp — and discarded, no cash-2Y level asserted). This is the **oil / term-premium signature**: an oil impulse lands on the long end, a growth/switch impulse on the front/belly — and tonight the premium is landing long, exactly where the 2Y falsifier leg is insulated. **This is the mirror image of Friday**, which was **2Y +14bp with the long end barely moved — a front-led bear-flattener read as credibility**; today is 2Y ~flat with the long end leading — two opposite shapes from two different shocks in three sessions. And it is the shape the **12Z window predicted in advance** — oil lands long, the 2Y insulated — so this is a **prediction MET on the intraday tape**, a step up from an observation recorded, though the settle is what scores it. **But this is INTRADAY CASH, not the CMT.** The 2Y scores only on tonight's CMT settle (~19:30Z, the 00Z window's), measured off Friday's **4.34**; a cash level is **not a band position and not a bp move to score**, and CMT prints to 1bp so a sub-2bp front tilt stays unresolvable even at the settle. Expectation-free read of the front vs Friday's 4.34: **inert intraday, no direction I would score** — defer it.
  - evidence: **Cash intraday (Yahoo CBOE, delayed, live US session): 30Y ~5.26% (+4.9bp), 10Y ~4.76% (+3.6bp), 5Y ~4.50% (+2.1bp) vs Friday's cash closes; ZT=F 2Y future ~unchanged (2YY=F stale, discarded). Last CMT settle Fri 08-28 2Y 4.34 (+14bp); tonight's CMT ~19:30Z scores at 00Z off 4.34. Cash ≠ CMT — no band position; CMT 1bp floor caps sub-2bp shape.**
  - uncertainty: 🟢 "no settle scores here; it defers to 00Z" is unambiguous by the clock rule; 🔵 the long-end-led steepener is a live cash read, but the CMT has printed against the intraday tape in both directions before, so the 2Y direction is held to the settle.

- 🟡 **THE OIL PREMIUM — peaked and easing, on repricing not a fresh shock; a dated read now calls it economic, not physical.** The premium that was *extending* at 12Z has **rolled off its pre-open peak**: **Brent BZ=F ~$88.26 / +2.48%** (Dec-mapped contract — direction only, front not quoted off this feed), **WTI ~$85.56 / +2.59%**, both down from the 12Z peak (+2.90% / +3.57%). A dated-2026 scan gives one real development since my 12Z reframe: **TradingEconomics (08-31)** reports traders increasingly reading the Iran situation as an **economic/sanctions confrontation rather than an imminent threat to physical supply**, citing a proposed **Iran–Oman corridor** and improving flows as reducing perceived supply risk. That corroborates the 12Z "not a closure, repricing not a second shock" read and now **dates** it. What I still will NOT assert: circulating **tanker-strike** reports remain **undated/multi-dated** (an Aug-8 ADNOC tanker, an Aug-27 report, a "this week" projectile hit) — the older-incident-re-served contamination trap, held unconfirmed. The dated, corroborated legs stay the weekend chain: **CENTCOM's strike on Iranian mine-laying launchers; IRGC retaliation intercepted over Jordan.** Bounded per the frame's per-market rule and **refuted for Korea** — the won firmed through the shock (Suri's, cross-referenced below).
  - evidence: **Brent BZ=F 88.26 / +2.48% (Dec-mapped, direction only), WTI CL=F 85.56 / +2.59% — both off the 12Z peak (+2.90% / +3.57%). Dated 08-31 (TradingEconomics): market reading Iran as economic/sanctions, not imminent physical-supply threat; Iran–Oman corridor proposal + improving flows cited. Tanker-strike reports undated/multi-dated (Aug-8 ADNOC / Aug-27 / "this week") — NOT asserted. Weekend chain (dated): CENTCOM launcher strike, IRGC retaliation intercepted over Jordan. Frame base Brent 88.58 Oct-26 (Tue, stale).**
  - uncertainty: 🟡 the escalation path is the uncertainty — the premium is easing on a de-escalatory economic read, so it deflates further if the weekend proves a one-off, and spikes on a *dated* second exchange or a confirmed closure; I hold the tanker/corridor items to a firmer date before either moves the read.

- 🔵 **THE US EQUITY TAPE — semis turned, the broad tape is soft: a rotation, not a rout, and nothing near the falsifier bar (which this window does not score).** Friday's semis-led de-rate did **not** extend into the cash session: **NVDA +0.95%** round-tripped up from Friday's −4.57%, **SOX +0.28%** green — while the **big three are mildly red (S&P −0.38%, Nasdaq −0.35%, Dow −0.59%)** and **VIX +4.6% (~15.1)**. Semis bid, broad tape soft — a modest risk-premium rotation, not a demand break (the frame's read: every de-rate so far has been valuation/financing). For the falsifier this is **context, not a score**: the index leg sits far below ±1.5% intraday, and by the clock rule the day's index leg is measured on the **20:00Z cash close** at the 00Z window, not here.
  - evidence: **Big three intraday −0.35% to −0.59% (S&P/Nasdaq/Dow), VIX +4.6% (~15.1) — % only, no-settle window. NVDA +0.95% (round-trip up from Fri −4.57%), SOX +0.28% (green) vs Fri SOX −3.47%. Cash close 20:00Z + CMT settle ~19:30Z both score at the 00Z window, not here.**
  - uncertainty: 🔵 intraday levels re-price into the close; the day's scoring instruments (cash close, CMT settle) are the next window's, so the semis-turn and the soft-broad-tape are set-up facts, not settled ones.

**Watch** — **Tonight's CMT settle (~19:30Z) and cash close (20:00Z) both score at the 00Z window**, not here: the 2Y leg on `ef57a4e` off Friday's 4.34, the index leg on the big-three strict rule (session one of two, never a trip); the intraday long-end-led steepener says watch whether the oil premium reaches the front or stays long · **the oil / Hormuz path** — peaked and easing on a dated economic-not-physical read; a *dated* second exchange or a confirmed closure reprices it hard, further de-escalation deflates it (tanker/corridor reports held unconfirmed) · **the won (Suri's gate 5)** — held past ±10 across three readings over ~11h but still `OPEN`/provisional, and the control leg is borderline: **DXY −0.29% (my pull, matches desk) is 0.01pp from the ±0.3% flat threshold** — Suri owns the adjudication; the live 2-session test is Tuesday · **Korea's flow (Suri's gate 4)** — unadjudicated a 3rd time, foreign still selling; Tuesday's jong-ga is the re-test
