## Pi native sessions
The bundled runtime auto-detects Pi's session store on the Gateway and paired
nodes. Stored sessions appear in the **Pi** sessions-sidebar group, with
transcript browsing from Pi's documented JSONL session format. Local rows also
offer **Continue**, which creates an OpenClaw session whose first turn resumes
the native Pi session through ACP. Pi retains the full model context from its
session file, and the catalog viewer continues to show that history. The new
OpenClaw transcript starts empty and records only subsequent turns. Paired-node
rows remain view-only. Custom session directories outside the store scanned by
`pi-acp` remain browse-only because the adapter cannot resume those files by id.
The catalog honors project and global `settings.json` session directories plus
`PI_CODING_AGENT_DIR` and `PI_CODING_AGENT_SESSION_DIR`. Relative paths resolve
from the directory containing their `settings.json` file.
Turn **Pi Session Catalog** off under **Config > Plugins > ACPX Runtime** to
disable discovery. It is enabled by default.
