+
+## Scope
+- `sprint263_plan.md`
+
+## Implemented
+
+New tool:
+- `tools/mcp/project_raw_candidate_structure.py`
+  - Normalizes raw tasks against top-gap missing-signal classes.
+  - Fills missing ops/reasons/execution contract fields.
+  - Expands shallow task sets to gap-indicated minimum count.
+
+Pipeline integration in `tools/mcp/run_sprint_taskitem_pipeline.sh`:
+- Added:
+  - `WSTONE_NATIVE_RAW_STRUCTURAL_PROJECTOR`
+- Raw candidate search now optionally projects:
+  - baseline candidate (`02ae_candidate_0_projected_tasks.json`)
+  - each generated candidate variant (`02ae_candidate_<n>_projected_tasks.json`)
+  - adaptive retry candidate when enabled
+- Added summary packet:
+  - `native_raw_structural_projector`

+  - `logs/taskitem_runs/01a_fallback_intake_spec_20260226_165746/02ae_candidate_0_projected_tasks.json`
+
+Observed result on hard sample:

+  - `best_failing_profile_count: 1 -> 0`
+  - `best_top_gap_score: 0 -> 88`
+  - `best_task_count: 2 -> 6`
+- Residual parity gap:
+  - `native_impact_coverage.failing_profile_count` remained `1`
+  - indicates score-tool vs coverage-gate semantics are not yet aligned.

+# Sprint 263 Plan: Raw Structural Projector Before Scoring
+
+## Goal
+Add a deterministic structural projector for raw candidate tasks before scoring so intrinsic search evaluates schema-normalized candidates (without full post-hardening stage).
+
+## Steps
+- Step 2363: Add raw candidate structural projector tool.
+- Step 2364: Apply projector to baseline/candidate/retry raw tasks before scoring.
+- Step 2365: Emit structural projector telemetry in summary.
+- Step 2366: Validate OFF/ON behavior on hard sample.
+- Step 2367: Add `Sprint263IntegrationSummary.h` and execution tracker.
