In-browser evidence-pack verifier

Kii-Anchorage reproducibility kit — Option C. Zero install. Nothing leaves your machine.

What this proves. It runs the same offline core as the shipped verify-pack --offline CLI, compiled to WebAssembly: it recomputes every body's commitment through the one ADR-003 scheme and checks it against the signed manifest (integrity — a tampered body is refused by name), verifies the BIP-340 signature over the manifest commitment (authorship), and replays the control chain (EV-1, I-1..I-6). What it cannot. It does not check the anchor on-chain (existence / time) — that needs a live testnet-10 node or explorer read (Check 4 in HOW-TO-VERIFY.md), which a page with no network cannot do; and it never proves the truth of the declared facts or bind the signing key to a named legal person. Read the DOES-NOT-PROVE block in the verdict as carefully as the rest.

Initializing verifier…

This page needs a local web server. Browsers block WebAssembly and module loading over file:// (CORS). From inside the kit directory, run one line — no install beyond Python:
python3 -m http.server 8000
then open http://localhost:8000/verify.html and reload.
