Tamper-evident verification for computational experiments. It binds a published result to the exact code, hardware, and time that produced it, in a cryptographically signed PDF anyone can verify. Works with any language, zero runtime dependencies, single static binary. Platform. Verify, seal, proofs, checkout, benchmark artifacts, provenance, and disclosure levels are cross-platform. The file/subprocess activity map and per-process hardware attribution are Linux-only today; elsewhere they fall back to system-wide readings.
