A package for converting to and from A1 spreadsheet notation

A1 — The cryptographic identity and authorization layer that turns anonymous AI agents into accountable, verifiable entities. One Identity. Full Provenance.

JWT/OIDC, OAuth2, and SPIFFE identity bridging for A1 — bind enterprise identities to Ed25519 delegation keys

This library is meant as a low-level library safely exposing different OS's abilities to perform non-blocking I/O.

无障碍（ACCESSIBILITY,A11Y,辅助功能）

Document model abstraction for accessibility rules: a DOM-shaped tree trait plus opt-in capability tiers for semantics, rendering and interaction.

Shared finding and report model for accessibility tooling: four outcome states, severity, WCAG mapping and a stable JSON contract.

Accessibility rules generic over the document model: one rule set for build-time, CI and in-page surfaces.

WASM boundary and arena adapter for the a11y rule set: run the same accessibility rules inside a live page.
