Verify a Rosalind receipt

Drag in (or paste) a *.manifest.json and this checks its tamper-evident BLAKE3 self-hash — entirely in your browser. Nothing is uploaded. Then edit a single character below and watch it flip to TAMPERED.

…or drop a .manifest.json onto the box. Edit any byte to see the hash break.
What this proves. It re-derives the receipt's own integrity — the manifest_blake3 over the canonical claim, plus the independent measurement_blake3 — the same check rosalind verify runs, minus re-hashing the input/output files (which aren't in your browser). It does not re-run the analysis. A VERIFIED receipt is intact and untampered; a single edited byte breaks the hash. Runs the same Rust verification code that ships in the CLI, compiled to WebAssembly via the rosalind-receipt crate.
