Noveum AI Gateway v2.0.0

This major release completes the production NovaGuard platform bridge across the native gateway and Cloudflare Workers, with cross-replica atomic admission/settlement, organization-scoped guardrails, provider-aware usage and pricing, and hardened release tooling.

Breaking changes

• MSRV is now Rust 1.94.1.
• AppState::new accepts the live-state, usage, admission, and shared-tenancy components.
• Policy::policy_type is now PolicyTypeTag; use kind() and type_name() for parsed and wire-level views.
• PolicyEngine::from_env is synchronous and returns Result<Self, String>.

Highlights

• Native and Cloudflare Worker platform-managed NovaGuard, including strict atomic reservations and complete/cancel/abandon settlement.
• Shared native tenancy with permission-complete credential resolution and organization counters across projects.
• A versioned policy schema with explicit rejection of malformed or unenforceable policies.
• Conservative strict admission for bounded, priceable requests; opaque or unpriceable inputs fail before provider execution.
• Current provider pricing with cache, long-context, server-tool, alias, and unknown-model handling.
• Authoritative buffered/SSE usage reconciliation, including Anthropic Messages-to-OpenAI tool/usage translation.
• Cloudflare Worker cache-generation protection, output-binding parity, deadlines before platform lease expiry, and 13-phase Workerd E2E coverage.
• Supply-chain hardening, strict rustdoc, Cargo packaging, Docker publishing, and hermetic CI gates.
