1"""Typed fault values for upstream OAuth/DCR failures (phase 1 of the MCP error-handling framework). 

2 

3The invariant this package exists to enforce: an upstream failure is classified ONCE into a single 

4fault value, and the response status, wire error code, and prose are all derived from that value. 

5Deriving all three from one classification makes contradictory pairings (a caller-fault error code on 

6a server-fault status) unrepresentable, and gives the trust-boundary rule one enforcement point: 

7spec-defined machine fields may cross to callers, upstream prose and raw bodies go to server logs.
