| Measured fixture results | Tested scale: 4× | Tested scale: 4× |
| Fixture findings | 4x upscaling of the 512×512 anchor to a native 2048×2048 PNG achieved 27.42 dB PSNR, 0.8876 SSIM, 0.6652 edge_corr, and 16.23 dB calibration plate PSNR with crisp lettering and line pairs. | Text was clear in this 4× output; the free-credit image carried a brand watermark. |
| Original historical observation | Uploading the 512×512 degraded anchor without login and selecting 4x produced a native 2048×2048 watermark-free PNG in 7.49s server time (PSNR = 27.42 dB, SSIM = 0.8876, edge_corr = 0.6652, plate_psnr_db = 16.23 dB) with sharp wooden sign text and micro calibration lines (02_workspace.png, 03_download.png). | PSNR=27.02dB · SSIM=0.8631 (4x 2048×2048 Prime model); outstanding edge_corr=0.7108, hf_ratio=0.7910, and plate_psnr=17.25dB with razor-sharp 'REALTEST 2026' and 'REALTEST 2048px GT' typography, though free-credit exports include a bottom-left Let's Enhance watermark. |

| Pricing transparency | 32.5 / 35 The landing page (01_landing.png) and pricing page clearly disclose free quotas (2 daily free guest credits without login, plus 5 bonus credits for new registered accounts) and credit costs (1 credit for 2x, 2 credits for 4x); in our no-login test, selecting 4x on the 512×512 anchor consumed 2 guest credits and exported a 2048×2048 watermark-free native PNG directly (02_workspace.png, 03_download.png). | 18 / 35 The home page (Screenshot ①) presents a drag-and-drop uploader that immediately redirects to `/signup` promising 'Get started with 10 images free' (Screenshot ④); signing in via Google grants 10 credits and unlocks Prime 4x (2048×2048), but the exported 2048×2048 JPG embeds a semi-transparent 'Let's Enhance .io' watermark in the bottom-left corner (Screenshot ③) that was not disclosed on the signup page. |
