# Skyhook Cargo — Kimi K3.1 Pro validation

- Artifact: `index.html` (6,484 bytes)
- Source: complete closing response from fresh generation agent `1a014fa4-f6a8-4e50-8bc9-ce7c24a72b4a`; packaged without operator code changes
- Runtime: Chrome `155.0.8059.84`, Node `v22.23.3`, offline `file://` CDP loads
- Review date: 2026-10-26

These are post-delivery operator checks, not authoring-agent claims or a complete rubric adjudication. One cross-check accelerated time by invoking the artifact's own `step(1/120)` with animation frames paused. Two separate real-time runs used CDP keyboard events and the normal animation loop without manually invoking `step`. None of the controllers assigned trolley/load positions, velocities, cable length, settle progress, or success state.

| Check | Result | Evidence |
| --- | --- | --- |
| Complete standalone document | Pass | Doctype and closing `</html>` present; one inline script parsed with `new Function`; no external assets or network APIs |
| Offline desktop | Pass | 1280×720 `file://` load produced one canvas and usable controls; no runtime errors, console errors, external requests, or horizontal overflow |
| Offline mobile | Pass | 390×844 load had no runtime errors, external requests, or horizontal overflow |
| Pause | Pass | Trolley/load state, cable, and settle state remained unchanged across a real-time paused interval |
| Drive, lag, and braking | Pass | After a 600 ms ArrowRight hold, trolley moved from 16 to 20.806 while load was 16.101; trolley speed was 14 and fell to 6.781 after release |
| Reel and constraint | Pass | ArrowUp reduced selected cable from 34 to 29.8; actual anchor/load distance was 29.8 |
| Deterministic reset | Pass | Restored trolley/load x=16, cable=34, zero settle, and normal playable state |
| Earned delivery | Pass, repeated twice | In two independent real-time runs from Reset, a keyboard-only controller used the normal animation loop to hoist, transfer, lower, damp swing, and deliver in 65.639 and 67.845 seconds. Both ended with contact `Pad`, settle 2.0 s, and actual cable 44 matching selected length 44. Speeds were 0.12491 and 0.06583; angles were 0.006526 and −0.005495 rad (about 0.37° and −0.31°) |
| Accelerated earned-delivery cross-check | Pass | A separate fixed-step, keyboard-event controller completed the same earned route at 52.875 simulation seconds. Final speed 0.10132; angle −0.006118 rad; contact `Pad`; settle 2.0 s |
| Mobile hold control | Pass | At 390×844, a real pointer hold on the on-screen right button moved the trolley; control stayed inside the viewport |
| Runtime during interactions | Pass | No uncaught exceptions during the targeted checklist and earned runs |

## Limits and unchecked items

- No numeric score or complete rubric passage is claimed. Screenshots were captured but not visually reviewed.
- Earned runs used real-time and accelerated automated controllers, not an uncut human video or independent anti-cheat review. They establish reachability through ordinary input events, not human difficulty or completion rate.
- The successful path hoisted above the tower. Exhaustive cable/tower contact, floor embedding, unsafe trolley movement, and explosive-collision cases were not reviewed.
- Pause during an active settle, every A/D/W/S variant, all on-screen buttons, and extended repeat/soak sessions beyond the three controller deliveries remain unreviewed.
