Sprint 92 Plan: Interop Testbeds and Reference Implementations

Context

External ecosystem adoption improves when reference implementations are available. Sprint 92 delivers interop testbeds and canonical references.

---

Goals

1. Build multi-language interop testbeds for common migration classes
2. Publish reference implementations for core specs
3. Validate third-party conformance against reference behavior
4. Reduce ambiguity in cross-vendor interpretation

---

Steps

Step 1149: Interop testbed manifest model (12 tests)

Step 1150: Reference implementation harness for IR/evidence specs (10 tests)

Step 1151: Third-party conformance replay runner (10 tests)

Step 1152: Canonical fixture and oracle dataset packs (10 tests)

Step 1153: Divergence triage model for interop failures (10 tests)

Step 1154: Interop certification policy bindings (8 tests)

Step 1155: whetstone_run_interop_testbed MCP tool (8 tests)

Step 1156: whetstone_get_reference_conformance_report MCP tool (8 tests)

Step 1157: Interop publication bundle (8 tests)

Step 1158: Sprint 92 integration summary + regression (8 tests)

Interop Rule

• Spec compliance claims require passing published interop testbeds.
