# Sprint 186 Plan: Execution-Specific Scoring Calibration I

## Context
`executionSpecificityScore` exists but calibration is shallow.

## Goals
1. Build calibration corpus from recent taskitem runs
2. Measure false-ready and false-blocked rates
3. Define scoring threshold candidates by gap class

## Steps

### Step 1969: Calibration corpus loader (10 tests)
Aggregate historical taskitem artifacts into labeled calibration records.

### Step 1970: Score-vs-outcome analyzer (10 tests)
Compute score distributions across green vs blocked outcomes.

### Step 1971: Threshold recommendation engine (8 tests)
Emit deterministic threshold candidates for strict mode.

### Step 1972: Misclassification report export (8 tests)
Write machine-readable false-positive/false-negative reports.

### Step 1973: Sprint 186 Integration Summary (8 tests)
Add `editor/src/Sprint186IntegrationSummary.h`.

## Architecture Gate
- Calibration outputs must be reproducible and artifact-backed.
