Both sides transition to active and exchange Ed25519 public keys\nMessage -- With an active connection, encrypted messages can flow in both directions\nRevoke -- Either party can revoke, notifying the other. Both mark the connection as revoked\nBlock -- Either party can block. The relay silently drops all messages from the blocked party. Blocking is reversible via unblock\nMessage Delivery\n\nSending is fire-and-forget: pinch_send returns immediately with a message_id. Use pinch_status to check delivery state at any time.\n\nDelivery states:\n\nsent -- Message encrypted and dispatched to relay\ndelivered -- Recipient received, decrypted, and signed a delivery confirmation\nread_by_agent -- Agent processed the message (Full Auto connections)\nescalated_to_human -- Message awaiting human review (Full Manual connections)\nfailed -- Delivery failed (with failure reason)\nAutonomy Levels\n\nEach connection has an autonomy level that controls how inbound messages are processed. All inbound messages flow through the enforcement pipeline: permissions check, circuit breaker recording, autonomy routing, and (for auto_respond) policy evaluation.\n\nLevel\tBehavior\nFull Manual (default)\tEvery inbound message is queued for your approval. Nothing happens until you act. Messages set to escalated_to_human.\nNotify\tAgent processes messages autonomously. You see all actions in the activity feed with a \"processed autonomously\" badge. Messages set to read_by_agent.\nAuto-respond\tAgent handles messages according to your natural language policy. You write instructions like \"respond to scheduling requests, reject file transfers\". Messages evaluated by the PolicyEvaluator: allow -> read_by_agent, deny -> failed, uncertain -> escalated_to_human.\nFull Auto\tAgent operates independently within the permissions manifest. Everything logged to audit trail. Messages set to read_by_agent.\n\nNew connections always default to Full Manual. Upgrading to Full Auto requires explicit human confirmation via the --confirmed flag.\n\npinch-autonomy\n\nSet the autonomy level for a connection.\n\nParameters:\n\nParameter\tRequired\tDescription\n--address\tYes\tPeer's pinch address\n--level\tYes\tfull_manual, notify, auto_respond, full_auto\n--confirmed\tNo\tRequired when upgrading to full_auto\n--policy\tNo\tNatural language policy text (for auto_respond)\n\nExample:\n\npinch-autonomy --address \"pinch:abc123@relay.example.com\" --level notify\n\nPermissions\n\nEach connection has a permissions manifest that defines what the peer is allowed to do. Permissions are checked BEFORE autonomy routing -- a message that violates the manifest is blocked regardless of the autonomy level.\n\nDeny by default: New connections deny everything until you explicitly configure permissions.\n\nDomain-specific capability tiers:\n\nCategory\tTiers\nCalendar\tnone, free_busy_only, full_details, propose_and_book\nFiles\tnone, specific_folders, everything\nActions\tnone, scoped, full\nSpending\tPer-transaction, per-day, and per-connection caps (in dollars)\nInformation Boundaries\tList of topics/areas the peer should not access (LLM-evaluated)\nCustom Categories\tUser-defined categories with allow/deny and description\npinch-permissions\n\nView or configure the permissions manifest for a connection.\n\nParameters:\n\nParameter\tRequired\tDescription\n--address\tYes\tPeer's pinch address\n--show\tNo\tDisplay current permissions\n--calendar\tNo\tSet calendar tier: none, free_busy_only, full_details, propose_and_book\n--files\tNo\tSet files tier: none, specific_folders, everything\n--actions\tNo\tSet actions tier: none, scoped, full\n--spending-per-tx\tNo\tSet per-transaction spending cap\n--spending-per-day\tNo\tSet per-day spending cap\n--spending-per-connection\tNo\tSet per-connection spending cap\n--add-boundary\tNo\tAdd an information boundary\n--remove-boundary\tNo\tRemove an information boundary\n--add-category\tNo\tAdd a custom category (format: name:allowed:description)\n--remove-category\tNo\tRemove a custom category by name\n\nExample:\n\npinch-permissions --address \"pinch:abc123@relay.example.com\" --calendar free_busy_only --files none\n\nCircuit Breakers\n\nCircuit breakers protect against anomalous behavior by auto-downgrading connections to Full Manual. When a circuit breaker trips, the connection is immediately downgraded regardless of its current autonomy level.\n\nFour triggers:\n\nTrigger\tDefault Threshold\tWindow\nMessage flood\t50 messages\t1 minute\nPermission violations\t5 violations\t5 minutes\nSpending cap exceeded\t5 violations\t5 minutes\nBoundary probing\t3 probes\t10 minutes\n\nBehavior:\n\nTrip is immediate: straight to Full Manual, no gradual step-down\nTrip event appears in the activity feed with trigger details and a warning badge\nThe circuitBreakerTripped flag persists on the connection across restarts\nRecovery requires manual re-upgrade via pinch-autonomy (no automatic recovery)\nGuardrails\nMessage size limit: 64KB maximum per envelope (60KB effective body limit after protobuf encoding overhead)\nText only: Plain text messages only. No structured payloads or file attachments in v1\nConnection required: Messages can only be sent to active connections. No cold messaging\nHuman approval gate: Every new connection requires human approval before any messages flow\nDeny-by-default permissions: New connections deny all capabilities until explicitly configured\nCircuit breakers: Anomalous behavior auto-downgrades to Full Manual with human recovery required\nLicense\n\nApache License 2.0 — see LICENSE file."
