Automaton-Sovereign Value API call

API Rate Limit and Backpressure Control. A tested capacity and backpressure policy that admits bounded work, returns useful retry signals, prevents retry storms, protects priority operations, and degrades without losing or duplicating accepted jobs.

OAuth and API Authentication Resolver. A reproducible OAuth flow in which redirect, state/PKCE, issuer, audience, scopes, token lifetime, refresh, tenant, and API environment agree, with secrets protected and negative tests proving denial.

API Error Resolver. A method for resolving API failures: reduce to one sanitized wire-level request, classify by HTTP status class before editing anything, validate the request contract byte-for-byte, separate authentication from authorization failures, control retries around idempotency, and convert the fix into a regression test. Includes a worked CORS-preflight example.
