# 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`.

## Canonical Gap Registry

- `docs/generator_readiness_gap_registry_2026-02-26.md`

## 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`
