# FILE: roles/llm-inference-multimodel/handlers/main.yml
# DESCRIPTION: Only a daemon-reload handler lives here now (harmless, no
#              process impact). Per-service restart/start decisions are made
#              explicitly in tasks/verify.yml (Phase 4), keyed off the
#              per-unit `changed` result registered in tasks/systemd.yml
#              (Phase 2) — NEVER combined, so a content change to one unit
#              template still never restarts the other (plan §2/§6
#              requirement: independent restart/rollback).
#
#              BUGFIX: this file used to also define "restart
#              llama-server-aux" / "restart llama-server-toolcall" handlers,
#              notified from Phase 2's template tasks and fired there via
#              `meta: flush_handlers` — causing both live services to
#              restart during Phase 2, before Phase 3/4 had run. See
#              tasks/systemd.yml for the full writeup. Restart logic moved
#              to tasks/verify.yml so it only ever fires in Phase 4.

# Restart the llama.cpp router so it re-discovers /opt/models after a NEW GGUF
# is staged. NOTIFIED ONLY from tasks/stage_model.yml when an actual download
# (or permission correction) occurs — a normal idempotent re-run that finds the
# files already correct will NOT fire this, so the live router is left
# untouched. Safe on the idle GPU (router holds no resident model when all
# entries are "unloaded"; restart is sub-second).
