Detect and reconcile drift between a feature flag's in-code SDK fallback default and its LaunchDarkly default rule (fallthrough), updating only the default argument without removing the flag or changing its evaluation. Co-authored-by: Cursor <cursoragent@cursor.com>

Only suites whose source actually changed since their last recorded score were re-run. Soft-failing while we stabilise the baseline. |
Add a promptfoo suite covering drift reconciliation, the no-drift (no code change, no PR) case, and a registry-declared default, asserting the agent resolves the fallthrough via get-flag and never mutates the flag. Register the suite in the manifest and add npm scripts. Co-authored-by: Cursor <cursoragent@cursor.com>
