## Desk frame
- **Held (the switch — the desk owns the frame):** the Fed/front-end is the switch. **This is the Monday 18Z window — the FIRST US session since Friday, but INTRADAY: US cash closes 20:00Z, AFTER our 18:45Z cutoff, so there is NO US settle; the settled curve, the settled closes, and the falsifier SCORE all DEFER to 00Z.** The curve is carried Friday direction-neutral (2Y 4.17 / 10Y 4.68 / 30Y 5.25). **No US settles block this window** — I published Friday's SP500 close (7,785.76) at 12Z, so a carried close is now PROSE, not a re-declaration (re-declaring it here would trip C1 BASE MISMATCH); the next settles block is Tuesday's 00Z off tonight's actual close. Korea is DARK (reopens Tue 08-18).
- **Falsifier — TRACKED, NOT scored this window (intraday; it scores at 00Z off the settled curve). Tracks does-NOT-trip:** the equity moves are small (S&P −0.4% intraday, well under the ±1.5% letter). Friday 00Z FINAL stands until the 00Z re-score.
- **Changed since 12Z:** **oil finally MOVED** — Brent **~$90.9 intraday, +2.7% vs Friday's $88.52** (Hormuz-deal hopes fading; Iran's Foreign Ministry said the US must lift its naval blockade before Iran will fully reopen the Strait), the **biggest move of the sequence** (REAL — WTI +2.6% and oilprice.com confirm, not a single feed); at ~+2.7% it is **essentially at the ~3% null threshold — the antecedent has now FIRED.** US equities modestly **RED** intraday (S&P −0.4%), the 10Y firmed with oil; **all intraday — the verdict defers to 00Z.**

- 🟡 **LEAD — the first US session since Friday is a risk-off-lite session with the oil spike finally arriving: Brent +2.7% intraday (the "prices-firm" counterweight firing for the first time), equities modestly red, the long end up — but the antecedent fired in the WRONG market: the US is a net energy EXPORTER, and every net-IMPORTER market that could test the Asia claim is CLOSED, so the channel is now testABLE but untested — the clean read waits for Korea's Tuesday reopen, not tonight.** The session is risk-off-lite, oil the driver: Brent jumped to **~$90.9, +2.7% vs Friday** (Yahoo BZ=F ~17:55Z; **WTI +2.6% and oilprice.com independently confirm — two benchmarks, two vendors, so this is not a single-feed print**) as hopes faded for a US–Iran deal to reopen the Strait of Hormuz (Iran's Foreign Ministry: no reopening "as long as the US naval blockade continues"). US equities are modestly red intraday (S&P ~7,755 / −0.4%, Nasdaq −0.3%, Dow −0.5%) and the 10Y firmed to ~4.72% intraday — the oil-negative-for-risk shape. **But be most skeptical of the tidy reading — oil-up-plus-US-stocks-down LOOKS like it confirms the channel, and it does not touch it. The US is a net energy EXPORTER, not the net importer the standing "oil-is-Asia-negative" claim requires.** So the US session tests the **inflation-risk-premium / Fed-path / risk-off** response in an economy that SELLS energy; it leaves **untested** the import-cost / currency channel — the Asia claim — which does not run through a net exporter either way. **And here is the sharp part: the antecedent (a real oil move) has finally fired, but NO net-importer market is open to price it.** Japan settled at 06:30Z, hours before the spike; Europe (a net importer) had already closed (~15:30Z) as the run built through the US afternoon; Korea is dark. The only market open to price the full move is the US — the wrong one. **So the claim stays UNADJUDICATED, and the clean test does not arrive tonight; it arrives at the first net-importer market to open AFTER the spike — Korea's Tuesday reopen, which catches up to the whole move at once.** (Tonight's 00Z US settle is a real read too, but of a DIFFERENT question — does the US front firm on the inflation impulse, i.e. dovish-durability — not the importer channel.) **NAME THE NULL: the Asia channel is CONFIRMED if, with oil elevated, a net-importer tape falls oil-shaped (energy importers lagging exporters, transport/utilities underperforming); it looks NOT-working if importers rise non-oil-shaped. Neither is observable today because no importer market traded the spike.** *(COI: n/a this item.)*
  - evidence: **First US session since Friday, INTRADAY (cash closes 20:00Z, after the 18:45Z cutoff — no settle). Oil the driver: Brent ~$90.9 / +2.7% (Yahoo BZ=F ~17:55Z; WTI +2.6% + oilprice.com confirm — not a single feed), essentially AT the ~3% null = antecedent FIRED — on fading US–Iran Hormuz-deal hopes (Iran FM: US must lift the blockade first). US equities RED intraday (S&P ~7,755/−0.4%, Nasdaq −0.3%, Dow −0.5%); 10Y ~4.72% intraday (+2–4bp). Oil-negative-for-risk SHAPE, BUT (1) intraday (2pm ≠ settle; archive of pares), (2) US = net energy EXPORTER → the mechanism is inflation-risk-premium/Fed-path/risk-off, NOT the import-cost channel the Asia claim rests on. THE ANTECEDENT (oil move) HAS FIRED but NO net-importer market is open to price it: Japan settled 06:30Z pre-spike, Europe closed ~15:30Z before the run, Korea dark. NULL: Asia channel confirms if a net-importer tape falls oil-shaped (importers lagging exporters); not-working if importers rise non-oil-shaped — neither observable today (no importer traded the spike). → UNADJUDICATED; clean test = Korea Tue reopen (first importer to open after the spike, catches the whole move). Tonight's 00Z US settle tests a DIFFERENT question (US front firms on the inflation impulse = dovish-durability), not the importer channel.**
  - uncertainty: 🟢 that oil moved materially and it is REAL, not a phantom — Brent +2.7% (Yahoo BZ=F), WTI +2.6% (Yahoo CL=F), and oilprice.com confirms both (two benchmarks, two vendors); driver two-sourced (CNBC/Al Jazeera Hormuz-deal-hopes-fading); US equities modestly red intraday; 🟡 that this does NOT cleanly test the Asia-net-importer claim (US is a net exporter; the move is ~at 3% but INTRADAY, and no importer market traded it); 🔵 the SETTLED curve, closes, and falsifier all DEFER to 00Z — every level here is INTRADAY, a 2pm print, not the settle.

- 🟡 **CURVE + THE FRONT (intraday) — the long end is firming with oil; the front's settled read, and the dovish-durability verdict, defer to 00Z.** The intraday curve response to the oil jump is a **long-end** move: the 10Y firmed to ~**4.72% intraday** (+2–4bp off Friday's 4.68) — the term-premium/oil impulse lifting the long end (the desk's oil-shock composition, not a growth shock). The front-specific 2Y I do NOT have a clean intraday read on (the futures-yield proxy was stale), and — critically — **the SETTLED curve, the flattener-vs-steepener composition, AND the falsifier score all DEFER to the 00Z settle**; a 2pm curve is provisional. The live question is whether tonight's settle shows the **2Y holding below 4.19 a THIRD session** (dovish-durability intact) or **firming back toward/above 4.19** on the oil/inflation impulse — **NAME THE NULL: dovish-durability BREAKS if the 2Y SETTLES back above 4.19** (reversing the two-session hold). I carry Friday's curve (2Y 4.17 / 10Y 4.68 / 30Y 5.25) direction-neutral; the settled read is 6h away. *(COI: the AI/growth complex names Anthropic related parties — Amazon investor, AMD counterparty, Nvidia/Micron peers — disclosed, on the merits.)*
  - evidence: **Intraday 10Y ~4.72% (+2–4bp vs Friday 4.68) = long-end/term-premium response to the oil jump (oil-shock = long-end-led). 2Y: no clean intraday read; SETTLED curve + steepener/flattener + falsifier all DEFER to 00Z. Dovish-durability NULL: breaks if the 2Y SETTLES back above 4.19. Curve carried Friday direction-neutral (2Y 4.17/10Y 4.68/30Y 5.25).**
  - uncertainty: 🟢 the 10Y firmed intraday with oil (long-end response); 🔵 the front-specific move, the settled curve, and the falsifier all DEFER to 00Z — intraday only, no settle asserted.

**Watch** — the **00Z Tuesday settle** scores the FRONT and the falsifier: does oil's +2.7% intraday spike HOLD into the close (or pare), does the 2Y hold below 4.19 a THIRD session or firm back on the oil impulse, does the falsifier score · oil / Hormuz — the spike finally makes the channel testABLE, watch whether it clears ~3% · **Korea reopens Tuesday** — the clean net-importer test of the oil channel (first importer to price the spike) + a two-session catch-up · **FOMC July 28–29 minutes Wednesday** · retail earnings (HD/TGT/LOW/WMT) from Tuesday · keywords: `oil spike REAL (Brent+WTI+2.7%), fired in a net-exporter tape` · `no importer market open — Asia channel testABLE not tested, waits for Korea Tue` · `settle + falsifier defer to 00Z`
