Side-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Open a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
Sour fish fried before eating; pH 4.3-5.3, protein 16-19%; keeps about 3 weeks (JIRCAS). Made in 4 steps over 5 days – 7 days. The longest step, ferment wrapped or in jars, takes 5–7 days (JIRCAS 1995) and runs at 30 °C. Salt is 2–11.1 % (JIRCAS 1995). Pediococcus pentosaceus and Lactobacillus alimentarius/farciminis do most of the fermenting.
Total time across the recorded steps: 5 days – 7 days

Variants
Plaa-som fak (som fak)minced or scraped fish pounded with rice, garlic and salt, wrapped in banana leaf; a fish "sausage" (see som-fak).
Koong-somShrimp made the same way; it turns pink (JIRCAS).
Safety
eaten fried; raw freshwater cyprinids carry liver fluke risk if undercooked (typical).
