# OWNS the Claude Dev Vault, so the obsidian-cli can't reach it), else falls back
# to the obsidian-cli. Both calls are wrapped in a hard timeout so a driver that
# can't reach the vault fails FAST instead of hanging forever (the overnight bug:
# reset-test-folder blocked >2min because `obs` targeted the main instance while
# obs-dev held the vault, with no timeout).
