mdMirror fallback directory resolves to CWD instead of ~/.openclaw/memory/md-mirror

[ScientificProgrammer]

Plugin Version

1.1.0-beta.10

OpenClaw Version

2026.4.9 (commit 0512059)

Bug Description

When mdMirror.enabled: true but mdMirror.dir is not set, the fallback directory resolves to {CWD}/memory-md instead of a stable absolute path like ~/.openclaw/memory/md-mirror.

In index.ts, createMdMirrorWriter() computes:

const fallbackDir = api.resolvePath(config.mdMirror.dir || "memory-md");

Since "memory-md" is a relative path, api.resolvePath() resolves it relative to the current working directory. During gateway startup, openclaw doctor runs, or CLI invocations, the CWD varies — so the mirror files end up in arbitrary locations and the following warning is logged on every plugin load:

[plugins] mdMirror: no agent workspaces found, writes will use fallback dir: /some/random/cwd/memory-md

The existing getDefaultDbPath() function already follows the correct pattern — resolving to ~/.openclaw/memory/lancedb-pro using homedir() + join(). The mdMirror default should follow the same convention.

This bug was identified with the assistance of Claude Code (AI). The accompanying fix PR was also AI-assisted.

Expected Behavior

When mdMirror.dir is not explicitly configured, the fallback should resolve to ~/.openclaw/memory/md-mirror (an absolute path inside the OpenClaw data directory), regardless of CWD.

Steps to Reproduce

1. Set plugins.entries.memory-lancedb-pro.config.mdMirror.enabled: true in ~/.openclaw/openclaw.json
2. Do not set mdMirror.dir
3. Restart the gateway (systemctl --user restart openclaw-gateway.service)
4. Observe the log warning showing the CWD-relative fallback path:

   [plugins] mdMirror: no agent workspaces found, writes will use fallback dir: /home/user/memory-md
   

5. Run openclaw doctor from a different directory — the fallback path changes to match that CWD
