/**
 * Antigravity reviewer repo-grounding tests (#2176)
 *
 * The agy block invoked the CLI without granting it the repo under review:
 * no --add-dir on either invocation arm, and no absolute repo-root anchor in
 * _AGY_PROMPT. The agent frequently anchored on its own
 * ~/.gemini/antigravity-cli/scratch dir, reviewed the plan text in isolation
 * (the exact failure the block's Review Instructions forbid), and its
 * ungrounded verdict flowed into the Consensus Summary at full weight,
 * undetected.
 *
 * These tests pin the fix: capability-probed --add-dir (mirrors the Codex
 * bypass-flag probe), absolute-root prompt anchor (agy AND the cursor-agent
 * block, which shared the anchor gap), a mandated self-report line, a stamped
 * blind-review marker, and consensus down-weighting of marked reviews.
 * Each assertion fails against the pre-fix block.
