# 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.
