AgentLedger

Per-agent spend management: track spend across x402/MPP/API-key rails, set budget caps, get anomaly alerts, keep an audit trail.

Card-drift history

Watching this agent since 2026-09-14T06:42:27Z. Hash = SHA-256 (16 hex) of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only edits don't count as drift. Feed: api/a2a-drift.json.
