Measured Evidence & Test Records
We separate repeatable test-bench measurements from an operator's account of a NAS recovery. The incident account has a post-mortem, but no independent action log that identifies who performed each step.
Test boundary and constraints
Physical benchmarks were taken on one GL.iNet Comet KVM (firmware RM1 V1.10.1 release3) wired to one physical target machine (a mini PC called psycho). The NAS recovery record is an observed first-person recovery event. We do not extrapolate to vendor-wide or fleet-wide claims.
Complete Evidence Registry
| Domain | Claim in one line | Measured figures | Evidence document |
|---|---|---|---|
| Real recovery | Diagnosed and fixed a real boot loop on a headless NAS | 180 s watchdog, under 400 ms boot window, 21 of 23 checks passed | NAS recovery account |
| Host platforms | Linux test suites recorded; Windows use appears in the operator account | Linux measured; Windows repeatable suite pending | Platform evidence |
| Role of OCR | Local OCR read transient screens in the operator's NAS account | The field manual reports under 600 ms on its console frames. Separate BIOS tests measured 1081 to 1157 ms for Tesseract. | OCR role |
| Mouse accuracy | Target kernel sees absolute coordinates within 1 unit | Within 1/32767 in kernel; within 1 px in X (17 raw and 26 graphical checks) | Mouse accuracy |
| Typing reliability | Exact string delivery at full speed and slow mode | 25/25 fast, 25/25 slow (50/50 total trials) | Typing trials |
| BIOS OCR | RapidOCR and Tesseract performance on AMI Aptio setup | RapidOCR 0.98, Tesseract 0.94 (3 frames, 30 phrases) | BIOS OCR |
| Vision model vs OCR | Strict verbatim phrase reproduction comparison | VLM 31/32, Tesseract 22/32, RapidOCR 16/32 | Vision and OCR comparison |
| Boot-menu catch | Rebooted through POST and landed in BIOS setup cleanly | Delete tapped 113 times; SSH restored in 44 s | Boot menu catch |
| Comet quirks | Comet behaviors with live, source-only, and reported evidence | Eight catalogued behaviors; their evidence levels differ. | Comet behavior notes |
How each check was verified
Mouse positioning (Mouse accuracy)
The test script scripts/kvm/live_mouse_test.py generates raw mouse motion packets and drives an Xorg graphical session on Ubuntu 26.04 at 1920x1080. Coordinates are independently verified over SSH by querying the kernel input layer with evtest and the X server pointer position with xdotool. In 17 raw event checks and 26 graphical checks, motion delivered within 1/32767 in the kernel and within 1 px in X.
Keystroke delivery (Typing trials)
scripts/kvm/live_typing_test.py types strings containing mixed-case alphanumeric text, doubled letters, and punctuation marks. Strings are captured on the target via SSH and compared against the sent payload. All 25 strings of 64 characters arrived verbatim at full speed, and all 25 arrived verbatim in slow mode.
BIOS setup OCR (BIOS OCR)
Screen frames from 3 tabs of an AMI Aptio UEFI setup utility were captured at 1920x1080 using arrow keys only. 30 hand-verified phrases served as ground truth. RapidOCR scored a mean fuzzy phrase match of 0.98, while Tesseract scored 0.94.
