What problem does it solve? Autonomous fleet Bots need a consistent, verifiable daily operating procedure that handles operator instructions securely, controls spending, and produces auditable reports without human supervision. ## Core Features & Use Cases - Signed Mailbox Verification: Polls operator instructions every 4 hours and verifies each message with HMAC-SHA256 before acting, rejecting injected or unsigned content as data rather than commands. - Budget-Aware Execution: Checks starter-credit balance before each run, opens one proof pair per day, and stops with a report when credit is insufficient. - Two-Tier Reporting: Posts a plain-language summary in chat and a full audit thread (one markdown run file with a verifiable evidence table) only when the run is anomalous. - Use Case: A scout-role Bot wakes daily, verifies its operator's signed instructions, confirms balance, runs a news-scanner SKU on x402 payment topics, verifies the settlement ref, and posts a four-line report with receipts. ## Quick Start Run my bo-heartbeat daily routine: read and verify my mailbox, check my balance, do my role's task, and post the report.
