# scripts/uninstall.sh — LaunchAgent + daemon teardown.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# bash scripts/uninstall.sh # remove LaunchAgent + kill daemon
|
||
|
|
# bash scripts/uninstall.sh --purge-state # also remove ~/.iai-mcp/.daemon.sock,
|
||
|
|
# # .daemon-state.json, .lock
|
||
|
|
# bash scripts/uninstall.sh --purge-data # also remove ~/.iai-mcp/lancedb +
|
||
|
|
# # runtime_graph_cache.json
|
||
|
|
# # DESTRUCTIVE — wipes user's brain.
|
||
|
|
#
|
||
|
|
# Idempotent: safe to re-run. Always exits 0 (best-effort).
|
||
|
|
# DRY_RUN=1 env skips real launchctl + kill + rm calls (used by tests).

# NOTE on shell flags: we deliberately use only `set -u`, NOT `set -e`.
|

# Uninstall must NEVER abort mid-flow — partial cleanup is worse than
|

|

# best-effort full cleanup. Each step prints its own outcome via ok/warn/die.
