Stress-test a deal before you call it committed on the forecast

I need an honest risk read on this deal before I call it commit on our forecast.

Deal: Vantage Freight Co., $68,000 ACV, expected close August 29, 2026.
Last contact: 11 days ago with the ops manager, not the VP who was on earlier calls.
Stakeholders engaged so far: one ops manager; no one from finance or leadership has joined a call.
Economic buyer confirmed: named but never joined a call — all info is secondhand from the ops manager.
Next step booked: no, they said they would "circle back after budget review".
Anything that's changed or gone quiet recently: went from replying same-day to no response in over a week.

Assess this deal against these known ways deals slip, and for each, tell me if it applies here and how strongly:
1. SINGLE-THREADED — only one stakeholder engaged, no relationship with the actual economic buyer
2. NO CONFIRMED NEXT STEP — momentum exists but nothing is calendared
3. VERBAL YES, NO PROCESS — enthusiasm without a confirmed decision process or timeline
4. GOING QUIET — a drop in responsiveness that doesn't match the stated urgency
5. COMPETITIVE OR STATUS-QUO RISK — a real alternative (including "do nothing") that hasn't been ruled out

Give me an overall risk level (Low/Medium/High) with the ONE reason driving that level, not an average of five scores. Then give me the single next action that would most reduce risk, not a list of five things to do.

Be willing to tell me this deal should move to a later quarter or be marked at-risk even if that's not what I want to hear going into the forecast call.
