 | 2026-02-26 | Codex | Sprint 169 implemented for production `run_pipeline` output: Python method receiver normalization (`self`/`cls` stripping), typed parameter/return extraction with text fallback, `__init__` field materialization, list literal handling, stronger C++ queue method typing, Rust/Go/Java method fallback scaffolding, and gate payload hardening (`reason` + `failure_reasons`). Rebuilt `whetstone_mcp` target and validated Python->C++ PriorityQueue sample with `overall_ready=true` plus production loop artifact at `logs/taskitem_runs/production_loop_20260225_181948`. |
 | 2026-02-26 | Codex | Sprint 170 implemented: `tools/mcp/evaluate_generated_code_gates.py` now executes real compile/test gates across C++/Python/Rust/Go, emits normalized diagnostics, and enforces strict-mode blocking on missing toolchain/failed gates. Added `editor/src/Sprint170IntegrationSummary.h` and taskitem artifact `logs/taskitem_runs/sprint170_plan_20260225_185146`. |
 | 2026-02-26 | Codex | Sprint 171 implemented: added deterministic remediation router (`tools/mcp/remediation_router.py`), upgraded production loop to chained generate→gate→pipeline-diagnostics→route with auditable `trace.jsonl` and explicit `green|blocked` contract, and added repeated benchmark runner `tools/mcp/run_production_benchmark_suite.sh`. Added `editor/src/Sprint171IntegrationSummary.h`; artifacts: `logs/taskitem_runs/sprint171_plan_20260225_185146`, `logs/taskitem_runs/production_loop_20260225_185133`, `logs/taskitem_runs/production_benchmark_20260225_185133`. |
+| 2026-02-26 | Codex | Sprint 172 executed: added deterministic compile-diagnostic include repair tool (`tools/mcp/apply_cpp_diagnostic_fixes.py`) and integrated auto-fix pass into production loop before blocked exit. Added `editor/src/Sprint172IntegrationSummary.h`; taskitem artifact `logs/taskitem_runs/sprint172_plan_20260225_190632`. |
+| 2026-02-26 | Codex | Sprint 173 executed: added pre-gate lint hook to `tools/mcp/evaluate_generated_code_gates.py` with explicit skipped/tool-missing signaling and optional strict lint blocking mode. Added `editor/src/Sprint173IntegrationSummary.h`; taskitem artifact `logs/taskitem_runs/sprint173_plan_20260225_190632`. |
+| 2026-02-26 | Codex | Sprint 174 executed: expanded debug-chain routing for include/compile classes in `tools/mcp/remediation_router.py`, added token-accounted A/B runner (`tools/mcp/run_ab_test_ast_vs_language_first.sh`) and estimator (`tools/mcp/estimate_tokens.py`), plus `editor/src/Sprint174IntegrationSummary.h`. Taskitem artifact `logs/taskitem_runs/sprint174_plan_20260225_190639`; strict production loop rerun reached `status=green` at `logs/taskitem_runs/production_loop_20260225_190639`. |

+## Goals
+- Step 1904: C++ include fixer from gate diagnostics (10 tests)
+- Step 1905: Loop integration for auto-fix attempt (8 tests)
+- Step 1906: Sprint 172 Integration Summary (8 tests)
+
+## Constraints
+- Missing STL include should not require manual prompt rewrite
+- Auto-fix must be auditable and idempotent
+
+## Dependencies
+- Existing editor/src modules and MCP toolchain
+- whetstone_mcp stable binary and workspace config
+
+## Acceptance Criteria
+- All sprint step tests pass
+- No regression in existing MCP tool behavior
+- Generated task queue is ready or blockers are explicit

+## Goals
+- Step 1907: Lint executor integration (10 tests)
+- Step 1908: Lint diagnostics normalization (8 tests)
+- Step 1909: Sprint 173 Integration Summary (8 tests)
+
+## Constraints
+- Lint status must never be silently dropped
+- Missing lint tool must be explicit (`skipped` + reason)
+
+## Dependencies
+- Existing editor/src modules and MCP toolchain
+- whetstone_mcp stable binary and workspace config
+
+## Acceptance Criteria
+- All sprint step tests pass
+- No regression in existing MCP tool behavior
+- Generated task queue is ready or blockers are explicit

+## Goals
+- Step 1910: Remediation router action expansion (10 tests)
+- Step 1911: Loop action execution contract (10 tests)
+- Step 1912: A/B + benchmark validation artifact update (8 tests)
+- Step 1913: Sprint 174 Integration Summary (8 tests)
+
+## Constraints
+- Debug chain must be executed, not only reported
+- Validation artifacts must quantify effect (quality + tokens + pass/blocked)
+
+## Dependencies
+- Existing editor/src modules and MCP toolchain
+- whetstone_mcp stable binary and workspace config
+
+## Acceptance Criteria
+- All sprint step tests pass
+- No regression in existing MCP tool behavior
+- Generated task queue is ready or blockers are explicit

+# Sprint 172 Plan: C++ Diagnostic Auto-Fix for Missing Standard Includes
+
+## Context
+Path B failures are currently dominated by deterministic compile errors like missing
+`<vector>` include despite emitted `std::vector` usage.
+
+## Goals
+1. Auto-repair common missing STL includes from compile diagnostics
+2. Integrate repair into strict production loop before declaring blocked
+3. Keep repair deterministic and fully traceable
+
+## Steps
+
+### Step 1904: C++ include fixer from gate diagnostics (10 tests)
+Implement diagnostic-driven include insertion tool:
+- parse missing-header hints from compiler stderr
+- add needed headers (`vector`, `map`, `set`, `optional`, `tuple`, `memory`)
+- preserve include ordering and idempotency
+
+### Step 1905: Loop integration for auto-fix attempt (8 tests)
+Wire include fixer into production loop:
+- run fix attempt after compile/test fail
+- re-run gates after fix
+- trace both pre/post fix gate states
+
+### Step 1906: Sprint 172 Integration Summary (8 tests)
+Add `editor/src/Sprint172IntegrationSummary.h` with:
+- steps_completed=3
+- cpp_include_autofix_active=true
+- loop_autofix_attempted=true
+- success=true
+
+## Architecture Gate
+- Missing STL include should not require manual prompt rewrite
+- Auto-fix must be auditable and idempotent

+# Sprint 173 Plan: Pre-Gate Static Analysis Hook
+
+## Context
+Compile/test gates catch hard failures, but we still need pre-gate static checks to
+surface maintainability and risk signals before final gate decision.
+
+## Goals
+1. Add static-analysis hook (best-effort, tool-aware)
+2. Report normalized lint diagnostics with deterministic schema
+3. Support optional strict lint blocking mode
+
+## Steps
+
+### Step 1907: Lint executor integration (10 tests)
+Add lint stage to gate evaluator:
+- C++: `cppcheck` when available
+- Python: `python -m pyflakes` when available
+- fallback to skipped with explicit reason
+
+### Step 1908: Lint diagnostics normalization (8 tests)
+Normalize lint outputs into shared diagnostic payload:
+- severity/category/file/line/message/raw_excerpt
+- deterministic ordering and truncation
+
+### Step 1909: Sprint 173 Integration Summary (8 tests)
+Add `editor/src/Sprint173IntegrationSummary.h` with:
+- steps_completed=3
+- static_lint_hook_active=true
+- normalized_lint_diagnostics_active=true
+- success=true
+
+## Architecture Gate
+- Lint status must never be silently dropped
+- Missing lint tool must be explicit (`skipped` + reason)

+# Sprint 174 Plan: Debug-Chain Wiring + Deterministic A/B Validation
+
+## Context
+We already have debug/remediation tools; they must be first-class in the automatic
+repair chain with measurable impact on A/B outcomes.
+
+## Goals
+1. Ensure loop uses debug-chain actions deterministically
+2. Produce explicit `green|blocked` outcomes with routed evidence
+3. Validate improvements via A/B and benchmark reruns
+
+## Steps
+
+### Step 1910: Remediation router action expansion (10 tests)
+Expand routing categories:
+- include/symbol/import failures -> deterministic repair action
+- compile structural failures -> pipeline diagnostics + generation refinement
+- behavior/test failures -> targeted behavior hints
+
+### Step 1911: Loop action execution contract (10 tests)
+Enforce deterministic action order:
+- action selection from router payload
+- bounded retries and explicit blocked reason
+- trace records for each executed action
+
+### Step 1912: A/B + benchmark validation artifact update (8 tests)
+Run:
+- strict A/B test with token accounting
+- strict production loop check
+- benchmark suite pass-rate summary
+
+### Step 1913: Sprint 174 Integration Summary (8 tests)
+Add `editor/src/Sprint174IntegrationSummary.h` with:
+- steps_completed=4
+- debug_chain_execution_active=true
+- deterministic_action_ordering_active=true
+- validation_artifacts_generated=true
+- success=true
+
+## Architecture Gate
+- Debug chain must be executed, not only reported
+- Validation artifacts must quantify effect (quality + tokens + pass/blocked)
