evidence: ponder 504 persistence check 2026-03-28
Test prediction #1185: ponder 504 Gateway Timeout is NOT persistent. Fresh stack start shows ponder healthy (<50ms, all 200 OK). Staking still blocked by webapp protocol-stats fetch issue. 0/5 personas completed staking, 5/5 wallet+buy succeeded. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
