 *
 * C2 (#2916) classification: **product-layer, stays product-side.** The DIF
 * `@kya-os/mcp` core does not generate `.well-known` manifests, and its
 * `buildDidWebDocument` is intentionally NOT adopted here: it produces a
 * byte-different DID document (full `kid` rather than a `#fragment`
 * verification-method id, emits both `publicKeyJwk` and `publicKeyMultibase`,
 * and requires a `did:web` DID). `did.json` is a W3C-standard wire artifact
 * that must stay byte-stable, so this generator is left in place and its wire
 * output is frozen by `__tests__/well-known-wire-freeze.test.ts`. Any future
 * relocation/rename is gated by the C4 (#2918) dual-accept window — never
 * change the `.well-known/did.json` path.
