Digital archival preservation and forensic media workflows require rigorous tools capable of inspecting raw media sectors, detecting physical bitrot, and validating image integrity without relying on opaque, unverified legacy utilities. Tawara is an optical and digital media verification scanner written in Rust and compiled to both native binaries and WebAssembly.

The core scanner performs streaming byte-level analysis, computing cryptographic checksums, sliding-window entropy distributions, and structural filesystem audits across ISO 9660, UDF, and raw sector formats. By compiling the core verification engine to WebAssembly, media audits run in fully isolated, client-side browser contexts with zero native dependencies.

Detailed error profiling visualizes block degradation, corrupted sector offsets, and track mastering discrepancies, producing deterministic audit ledgers for long-term data preservation.

Status: active core engine and WebAssembly verification pipeline. Source is proprietary.
