+# Trajectory: Add JSONL ledger to relay-pty for crash recovery and durability

+> **Status:** ❌ Abandoned
+> **Task:** agent-relay-547
+> **Started:** January 29, 2026 at 09:54 AM
+> **Completed:** January 29, 2026 at 09:54 AM

+
+## Key Decisions
+
+### Use JSONL instead of SQLite for relay-pty ledger
+- **Chose:** Use JSONL instead of SQLite for relay-pty ledger
+- **Reasoning:** JSONL is simpler than SQLite, no native dependencies, append-only is sufficient for this use case, easy to debug/inspect, and matches existing JSONL patterns in the codebase
+
+---
+
+## Chapters
+
+### 1. Work
+*Agent: default*
+
+- Use JSONL instead of SQLite for relay-pty ledger: Use JSONL instead of SQLite for relay-pty ledger
+- Abandoned: Deferring implementation - bead agent-relay-547 created for future work
