# Sprint 187 Plan: Execution-Specific Scoring Calibration II

## Context
Calibration must generalize beyond single-sprint corpora.

## Goals
1. Add cross-project calibration datasets
2. Tune score penalties for weak grounding
3. Validate threshold stability across corpora

## Steps

### Step 1974: Cross-project calibration ingestion (10 tests)
Load calibration data from sprint plans and run-spec families.

### Step 1975: Penalty tuning for generic taskitems (10 tests)
Tune penalties for weak file/tool/test grounding.

### Step 1976: Stability checker across datasets (8 tests)
Compare threshold drift across cohorts.

### Step 1977: Deterministic threshold profile selection (8 tests)
Select strict profile with deterministic tie-breaking.

### Step 1978: Sprint 187 Integration Summary (8 tests)
Add `editor/src/Sprint187IntegrationSummary.h`.

## Architecture Gate
- Selected thresholds must remain stable across at least three dataset cohorts.
