When building the gateway install plan, read and parse
~/.openclaw/.env (or $OPENCLAW_STATE_DIR/.env) and merge those
key-value pairs into the service environment at the lowest
priority — below config env vars, auth-profile refs, and the
core service environment (HOME, PATH, OPENCLAW_*).
This ensures that user-defined secrets stored in .env (e.g.
BRAVE_API_KEY, OPENROUTER_API_KEY, DISCORD_BOT_TOKEN) are
embedded in the LaunchAgent plist (macOS), systemd unit (Linux),
and Scheduled Task (Windows) at install time, rather than
relying solely on the gateway process loading them via
dotenv.config() at startup.
Previously, on macOS the LaunchAgent plist never included .env
vars, which meant:
- launchctl print did not show user secrets (hard to debug)
- Child processes spawned before dotenv loaded had no access
- If the same key existed in both .env and the plist, the stale
plist value won via dotenv override:false semantics
Dangerous host env vars (NODE_OPTIONS, LD_PRELOAD, etc.) are
filtered using the same security policy applied to config env
vars.
