- hardening of API transport adapters and middleware behavior across protocol surfaces
- expansion of benchmark-backed confidence for request parsing, execution bridging, and serialization paths
- strengthening of observability and reliability behavior under concurrency and degraded conditions
- transport-facing contracts remain backward compatible within major release line.
- adapter behavior remains fail-closed on invalid or unsupported protocol input.
- high-concurrency paths remain bounded by explicit runtime controls.
- observability integration must not compromise request-path correctness.
| Interface | Requirement |
|---|---|
| GraphQL interfaces | deterministic parse/execute behavior and subscription transport stability |
| gRPC interfaces | explicit adapter error semantics and lifecycle consistency |
| WebSocket interfaces | bounded queue/session behavior with clear failure contracts |
| tracing/export interfaces | bounded, observable, non-intrusive telemetry behavior |
- standardize transport-level error classes and response semantics.
- reduce ambiguity in optional capability handling for API surfaces.
- expand direct benchmarking of parser, serialization, and endpoint execution paths.
- tighten diagnostics and operator observability for protocol failures.
- focused unit and integration tests across GraphQL/gRPC/WebSocket adapters.
- concurrency and load tests for queueing, parsing, and session handling paths.
- deterministic fixture tests for degraded/unsupported capability modes.
- release-profile benchmark runs for mapped API performance targets.
- parser and adapter hot paths stay within release baseline regression budgets.
- correlation/tracing overhead remains bounded in low-latency request paths.
- benchmark manifest completeness reaches no-missing-case status for mapped API targets.
- continue authn/authz enforcement checks across all transport entry points.
- enforce fail-closed behavior for malformed payloads and unsupported protocol states.
- maintain bounded resource behavior for connection and queue-heavy workloads.
- keep operational diagnostics actionable for production incident triage.
