Operators: flagged? re-verify now

Flags and this score update automatically on the free probe cycle (~29h). If you fixed an issue and need fresh public evidence immediately: instant re-verification ($0.25, x402) — an immediate GET probe, score recompute with the same public formula, and recovery events to the public feed. Buys speed and evidence only; the score itself cannot be bought.
