# Sprint 249 Plan: Raw Candidate No-Uplift Guardrail

## Goal
Prevent false confidence from raw candidate search runs that try variants but produce no measurable uplift.

## Steps
- Step 2290: Add baseline vs best raw candidate comparison telemetry.
- Step 2291: Emit raw candidate search artifact for every enabled run.
- Step 2292: Add optional hard-fail guard when no failing-profile uplift is achieved.
- Step 2293: Validate expected pass/fail behavior for guardrail mode.
- Step 2294: Add `Sprint249IntegrationSummary.h` and execution tracker.
