Summary

Documents vault passkeys, now available in the API, the Node, Python, and Go SDKs (0.131.0), and the CLI (0.50.0).

• New page vaults/passkeys: adding a passkey field, register_passkey to create a passkey on a website, importing a passkey as a CXF value, arm_passkey to sign in, disarm_passkey, CLI usage, and behavior and limits (one armed passkey per website per browser, one pending registration per browser, counter 0 with backup flags, ES256 only, new-tab reload, collection forms and vault-react 0.4.0 leaving passkey fields out, 409 on browsers whose image doesn't support passkeys). It includes the security warning that while a passkey is armed, any script on the website's pages can obtain a sign-in.
• vaults/credentials: passkey added to the field types. The "field definitions are immutable" paragraph is replaced by a new Add or remove fields section for spec.add_fields and spec.remove_fields, with examples. Forms and custom collection surfaces omit passkey fields, and a Use passkeys section links to the new page.
• vaults/overview: one paragraph pointing to passkeys.
• docs.json: adds the page to the Vaults group after Credential Items.

Validation

• Every TypeScript example on both pages type-checks with tsc --strict against @onkernel/sdk 0.132.0, and every Python example compiles.
• Behavior statements were checked against the API's OpenAPI descriptions and the signer code (for example, allowCredentials matching and NotSupportedError for non-ES256 requests).
• The broken-links check passes. I couldn't run the local preview server in my environment, so the rendered pages haven't been viewed.

approved with one request:

• in vaults/passkeys.mdx:170 the Python import example uses os.environ without importing os, so it fails when copied as shown. add import os to the block.
