Progress Log - 2026-02-26

Scope Covered Today

• Sprint tranche execution and validation from 206 through 227.
• Hard benchmark reruns on:
  • challenging_subset_prod_2026-02-26.jsonl
  • challenging_fullstack_multifile_2026-02-26.jsonl
• Production-loop anti-false-green hardening, projection/fullstack contract enforcement, parity gating, and parity remediation.

Key Outcomes

1. Sprints 206-211:

• Added anti-false-green production evidence gating.
• Added projection-contract validation and parity/efficiency/intent consistency analyzers.
• Status: PARTIAL (diagnostics/enforcement improved, parity and readiness still weak at that stage).

2. Sprints 217-221:

• Implemented multi-file/fullstack contract gates (migration/security/SLO/rollout checks).
• Added fullstack closure analyzer and execution tracker.
• Status: IMPLEMENTED, then PARTIAL until parity inconsistency was addressed.

3. Sprints 222-224:

• Added strict AB/production parity hard gate and summary metrics.
• Eliminated unresolved divergence by blocking inconsistent runs.
• Status: DONE (for gating/reporting behavior).

4. Sprints 225-227:

• Added deterministic path-B repair layer:
  • C++ include repair for std::vector.
  • Go/Rust queue transpile skeleton normalization.
• Integrated repair into AB path-B flow.
• Fixed Rust gate harness initialization issue.
• Validation result on latest reruns:
  • challenging_subset_prod_20260226_r7: ab_prod_divergence_count=0, ab_consistency_blocked_count=0
  • challenging_fullstack_multifile_20260226_r7: ab_prod_divergence_count=0, ab_consistency_blocked_count=0
• Status: DONE.

Remaining Risk (Important)

• Current path-B repair closure is pattern-driven around recurring queue-shaped transpile failures.
• Next required tranche: broaden to non-queue semantics and first-class spec-to-execution-ready planning.

Added After Commit 55876d3 (Same Day Continuation)

• Wired first-class planning precheck into tools/mcp/run_sprint_taskitem_pipeline.sh.
• Added environment controls:
  • WSTONE_SPEC_READINESS_PRECHECK
  • WSTONE_SPEC_READINESS_HARD_GATE
  • WSTONE_SPEC_READINESS_MIN_SCORE
• Spec readiness is now available in pipeline 00_summary.json as planning_readiness.
• Added auto-hardening utility:
  • tools/mcp/spec_planning_hardener.py
• Added end-to-end hardening gate wrapper:
  • tools/mcp/run_spec_hardening_gate.sh
• Demonstrated hard-gate delta on sprint sample:
  • original spec blocked (rc=7, score 17)
  • hardened spec passed (rc=0, score 100)
• Executed batch hardening on real corpora:
  • drive specs (7)
  • example product meta specs (10)
• Batch report:
  • docs/spec_hardening_batch_report_2026-02-26.md
• Artifact isolation update:
  • moved planning/hardening outputs to logs/taskitem_runs/TEST_ONLY_* paths.
  • wrapper default now writes to TEST_ONLY_spec_hardening_gate_*.

Sprint 232 Added (Same Day)

• Added semantic planning bridge:
  • tools/mcp/markdown_to_semantic_annotations.py
• Integrated into taskitem pipeline:
  • tools/mcp/run_sprint_taskitem_pipeline.sh
  • env toggle: WSTONE_SEMANTIC_PLANNING_BRIDGE (default 1)
  • emits 00b_semantic_planning_annotations.json
• summary now includes semantic_planning_annotations

Sprint 233 Added (Same Day)

• Added semantic-bridge decomposition tooling:
  • tools/mcp/augment_spec_with_semantic_packet.py
• Pipeline now supports:
  • semantic intake augmentation
  • semantic requirement injection
  • semantic task expansion
• A/B run shows measurable decomposition delta (TEST_ONLY artifacts):
  • validation taskitems 2 -> 8
  • avg execution specificity 75.0 -> 84.75

Sprint 234 Added (Same Day)

• Added semantic quality gate tooling:
  • tools/mcp/check_semantic_planning_gate.py
• Integrated optional semantic gate into pipeline with hard-fail behavior.
• Smoke-verified gate-enabled run (TEST_ONLY):
  • logs/taskitem_runs/TEST_ONLY_sprint234_semantic_gate_smoke_20260226/00_summary.json
