Architecture

The React workbench retains browser File handles only in component memory. core/repro.ts normalizes paths, streams the operation one file at a time through Web Crypto, emits a versioned stable manifest, compares indexed paths and writes a deterministic, uncompressed ZIP with CRC-32 values from the shared helper package. Generated manifests omit clock time by default.

The signature layer generates a non-exportable ECDSA P-256 private key and exports only its public JWK. Relative assets allow nested Toolbox deployment. Release packaging normalizes file order, permissions and timestamps and emits a SHA-256 sidecar.
