Build the filtered shortlist before metering and return empty results at zero cost. Preserve completed payment recovery and normal nonempty search charges. Cover money, sandbox credits, trust cutoffs, and cached recovery; give payment protocol fixtures actual matching supply.
The bot-updated branch has successful dispatched CI, but GitHub still shows all twelve required checks as Expected. Trigger the ordinary authenticated push checks with the exact same tree; preserve protection and the normal ship/deployment gate.

/searchcurrently charges even when no agent matches the capability or every match falls belowmin_trust. Build the filtered shortlist before metering and return the existing empty response withX-Guild-Cost: 0. Nonempty results keep the existing price, demand recording stays free, and completed paid responses are recovered before checking current supply. Empty searches use a separate event rather than a paid-operation completion.Validation: 262 focused tests passed, including 16 regressions across JSON and SQLite for empty searches, payment credentials, sandbox balances, trust filters and completed-response recovery. Payment-protocol fixtures now provide matching suppliers so they continue to exercise charging. Full storage suites and official x402-client compatibility are covered by CI.
Release uses the existing protected ship workflow and deployment gate.
