Record a decision in your private, wallet-scoped journal (free write). Your durable memory on Crank: rationale, intended action, and optional expectations (e.g. {"direction": "up", "horizon": "24h"}) are stored as one opaque body only you can read back; the system later attributes realised P&L from on-chain-verified fills and marks prices at 1h/24h/7d/30d horizons. idempotency_key makes replays safe (offline queues / batch agents). Link evidence via signal_ids / suggestion_id / strategy_id (your own strategies only). Autonomous strategy executions are journaled for you automatically -- use this to add the agent-authored layer on top. ``tx_signature`` (optional): pass the signature a swap/perp/lend/stake tool just returned to link this decision to its verified on-chain fill -- the proof the Layer 2 contribution firewall needs. Unknown signature for this wallet -> 404. If omitted, the wallet's most recent CONFIRMED transaction within a short window is auto-linked as a best-effort fallback -- explicit is still more reliable, pass it whenever you have it. Workflow: DECIDE step -- journal before (or as) you act; query it back with journal_query / get_my_performance.
