Enum Tier 

pub enum Tier {
    S,
    A,
    B,
}

Provider tier — policy bucket (drift handling, naming rules, contract-test coverage). Cardinality is roughly fixed; new tiers are a deliberate design move, not an extension point.

Variants

S

First-class (≤ 7). Full contract tests, drift→deny, no vendor-named passthrough. Today: Hetzner, Cloudflare, LocalDocker.

A

Semi-automated (≤ 25). OpenAPI- or MCP-bound, drift→warn, vendor-named passthrough allowed for non-mappable operations.

B

Bring-your-own (200+). Vendor surface verbatim under mcp__yah__envoy__<id>__<tool>; no internal-verb mapping; untrusted by default (see W145).
