Webhook buffer grows unbounded — crashes with V8 string length error

[warren-t-c]

Problem

The webhook buffer file (.data/webhook-buffer/webhook-github.jsonl) grows without bound. After accumulating ~37k events over a few weeks of active use, it reached 560MB and OrgLoop crashed on startup with:

Failed to start: Cannot create a string longer than 0x1fffffe8 characters

The process stays alive (systemd reports active (running)) but the event loop never starts — all incoming events are silently dropped.

Expected Behavior

The buffer should have rotation, truncation, or a size cap so it doesn't grow forever. Processed events should be prunable.

Suggested Fix

Options (any would work):

1. Auto-rotate — truncate processed events after successful delivery
2. Size cap — drop or archive oldest events when file exceeds a configurable limit
3. Stream reading — don't load the entire file into a single string; read line-by-line

Environment

• OrgLoop CLI (latest as of 2026-03-28)
• Node.js v22 on Ubuntu 24.04 ARM64
• ~37k GitHub webhook events over ~3 weeks of use
