Follow-up to closed issue #22. ampere (CoolPi GenBook RK3588) still runs the pre-1.2.1 fork-and-drift pattern: a local /opt/lmcp/server.lua override that hand-merged fetch + web_search tools instead of using the packaged copy. After v1.2.1 cutover the tools migrate to tools.d/ plugins, override goes away, future apt upgrade lmcp deliveries land cleanly.

Pre-staging needed (when ampere is up)

Audit /opt/lmcp/ for existing overrides + identify ampere-specific tools to migrate (likely just fetch + web_search, but check)
Lift any ampere-specific tools into /opt/lmcp/tools.d/ampere.lua plugin shape (analogous to hertz.lua, 9756 bytes)
Verify with lua5.4 -e "dofile(/opt/lmcp/tools.d/ampere.lua)" syntax check

Cutover sequence (mirror of hertz, ~1 minute hands-on)

# 1. Upgrade to v1.2.1
sudo pacman -Syu lmcp     # ALARM
# OR: sudo apt update && sudo apt install lmcp  (if ampere on Debian variant)
pacman -Q lmcp            # confirm 1.2.1

# 2. Rewrite /etc/systemd/system/lmcp.service:
#    ExecStart=/usr/bin/lua5.4 /usr/share/lua/5.4/server.lua
#    Environment=LMCP_NAME=ampere-tools
#    Environment=LMCP_HOST=192.168.88.115   # or .80, check actual
#    Environment=LMCP_PORT=8080
#    Environment=LMCP_CONF=/opt/herding/etc/ampere-tools.conf
#    Environment=LMCP_TOOLS_DIR=/opt/lmcp/tools.d

# 3. Archive override
sudo mv /opt/lmcp/server.lua /opt/lmcp/server.lua.pre-tools.d.bak.$(date +%Y%m%d)

# 4. Restart + verify
sudo systemctl daemon-reload && sudo systemctl restart lmcp
systemctl is-active lmcp
# Expect tools/list to show 9 packaged + N ampere-specific (likely 9 + 0 = 9 if no ampere-specific tools beyond what is packaged)

Blocker

ampere is a laptop without remote wake (no WoL/IPMI/smart-plug power-cycle on the ampere DECT outlet). Needs physical lid-open + login. Last verified powered-off 2026-05-18 ~03:00 (per shutdown sequence after the data + nuccies poweroff).

Low priority — fetch/web_search are now available via hertz-tools (closes the user-facing symptom). ampere just runs lmcp internally; clean-up is for pattern hygiene + future-proofing against override drift.
