Sprint 166/167/168 Taskitem Execution Log (2026-02-26)

MCP taskitem runs

• logs/taskitem_runs/sprint166_plan_20260225_175406
• logs/taskitem_runs/sprint167_plan_20260225_175406
• logs/taskitem_runs/sprint168_plan_20260225_175406

All three runs completed with queue-ready taskitems and successful validation.

Implemented work mapping

Sprint 166

• Added class/module generation path for generateCode:
  • editor/src/AgentCodeGen.h
• Added production quality scoring helper:
  • editor/src/GenerationQualityGates.h
• Exposed quality + gate metadata in generateCode and runPipeline RPC responses:
  • editor/src/headless_rpc/DispatchPart1.h
  • editor/src/AgentRPCHandler.h
• Added integration summary artifact:
  • editor/src/Sprint166IntegrationSummary.h

Sprint 167

• Added offline production gate evaluator:
  • tools/mcp/evaluate_generated_code_gates.py
• Added gate metadata to runtime tool responses (compile/test/placeholder/overall):
  • editor/src/headless_rpc/DispatchPart1.h
  • editor/src/AgentRPCHandler.h
• Added integration summary artifact:
  • editor/src/Sprint167IntegrationSummary.h

Sprint 168

• Added closed-loop production completion runner:
  • tools/mcp/run_production_completion_loop.sh
• Added integration summary artifact:
  • editor/src/Sprint168IntegrationSummary.h

Verification runs

Rebuild + promote

• Rebuilt and promoted stable MCP binary:
  • editor/build-native/releases/whetstone_mcp_20260225_180207
  • editor/build-native/whetstone_mcp_stable

A/B rerun (post-implementation)

• Run directory:
  • logs/taskitem_runs/ab_test_ast_vs_language_first_20260226_180215

Observed result:

• Path A whetstone_generate_code now emits class/module output for PriorityQueue spec with gate result overall_ready=true.
• Path B whetstone_run_pipeline continues to emit structural class output, but gates correctly flag non-production shape (overall_ready=false) due placeholder-like method signatures and incomplete data model.

Closed-loop production completion

• Run directory:
  • logs/taskitem_runs/production_loop_20260225_180220

Result:

• overall_ready=true within iteration budget for PriorityQueue spec.

MCP versioning/compatibility rollout (2026-02-26)

Implemented baseline compatibility/versioning support for multi-agent MCP usage:

• Added MCP runtime/tool version metadata in protocol responses:
  • editor/src/MCPServer.h
  • editor/src/mcp_main.cpp
• Added compatibility docs + machine-readable ledger:
  • docs/mcp_versioning_and_compatibility.md
  • docs/mcp_compatibility_ledger.json
  • tools/mcp/README.md (version check flow)
• Added MCP tool for agents to query compatibility data directly:
  • editor/src/mcp/RegisterCompatibilityTools.h
  • registered via:
    • editor/src/mcp/RegisterOnboardingAndAllTools.h
    • editor/src/MCPServer.h include

Validation:

• Rebuilt target: whetstone_mcp
• Verified tools/call:
  • whetstone_get_compatibility_ledger returns:
    • runtime header (runtimeVersion, toolSurfaceFingerprint, etc.)
    • parsed ledger contents from docs/mcp_compatibility_ledger.json
