Problem

SQLITE_CANTOPEN errors cause the gateway process to exit when running as a LaunchAgent on macOS. The same error is survived in terminal mode because it's caught by local try/catch handlers, but when it escapes to the global unhandledRejection handler, it falls through to process.exit(1) because it's not in any safe-list.

This creates a crash loop under launchd: crash → restart → crash → throttle → silent death.

Root Cause

In src/infra/unhandled-rejections.ts (compiled to audio-transcription-runner-*.js), the error classification has:

• FATAL_ERROR_CODES → exit(1)
• CONFIG_ERROR_CODES → exit(1)
• TRANSIENT_NETWORK_CODES → log and continue
• Everything else → exit(1)

SQLite transient errors (SQLITE_CANTOPEN, SQLITE_BUSY, SQLITE_LOCKED, SQLITE_IOERR) are not in any safe-list. They fall through to the catch-all process.exit(1).

Proposed Fix

Add a TRANSIENT_SQLITE_CODES set (or add to the existing transient set):

const TRANSIENT_SQLITE_CODES = new Set([
  "SQLITE_CANTOPEN",
  "SQLITE_BUSY", 
  "SQLITE_LOCKED",
  "SQLITE_IOERR"
]);

And check it in installUnhandledRejectionHandler alongside isTransientNetworkError.

Environment

• OpenClaw v2026.3.2
• macOS (arm64), Node v25.6.1
• LaunchAgent plist with correct TMPDIR, HOME, PATH, WorkingDirectory
• QMD auto-update disabled (interval: 0)
• Related: LaunchAgent plist missing TMPDIR causes SQLITE_CANTOPEN on macOS #20489 (TMPDIR fix doesn't apply here), Unhandled fetch rejection crashes gateway, launchd throttles after crash loop #14649 (same crash-loop pattern)

Workaround

Manually patching the compiled dist files to add SQLite codes to TRANSIENT_NETWORK_CODES. This survives until the next openclaw update.
