# Sprint 233 Execution Tracker - 2026-02-26

## Scope
- `sprint233_plan.md`

## Implemented

Tooling added:
- `tools/mcp/augment_spec_with_semantic_packet.py`

Pipeline integrations in `tools/mcp/run_sprint_taskitem_pipeline.sh`:
- `WSTONE_SEMANTIC_INTAKE_AUGMENT` (default `1`)
- `WSTONE_SEMANTIC_REQUIREMENT_INJECTION` (default `1`)
- `WSTONE_SEMANTIC_TASK_EXPANSION` (default `1`)
- Summary fields:
  - `semantic_intake_augment`
  - `semantic_requirement_injection`
  - `semantic_task_expansion`

## A/B Evidence (TEST_ONLY)

Compared same drive spec with semantic bridge disabled vs enabled:
- base run:
  - `logs/taskitem_runs/TEST_ONLY_sprint233_base_no_semantic_20260226_143211/00_summary.json`
- semantic bridge run:
  - `logs/taskitem_runs/TEST_ONLY_sprint233_semantic_bridge_20260226_143213/00_summary.json`

Observed delta:
- `validation.total_taskitems`: `2 -> 8` (delta `+6`)
- `validation.average_execution_specificity_score`: `75.0 -> 84.75` (delta `+9.75`)
- `semantic_requirement_injection.injected_count`: `0 -> 10`
- `semantic_task_expansion.expanded_task_count`: `0 -> 6`

## Explicit Completion Signal

- Sprint 233: `DONE` (implemented + integrated + measurable decomposition delta)

## Residual Risk

- Semantic bridge currently improves differentiation via deterministic expansion heuristics.
- Next step is generator-native semantic consumption to reduce reliance on bridge-side expansion.
