# Prefer the local per-host pixi mirror in ~/bpy (see pixi_local_sync.sh)
# over the shared NFS install, for speed -- but only once verified
# identical: pixi.lock fully determines what gets built (see chat), so a
# byte-for-byte match against the shared lock means the local bpy312 is
# guaranteed the same as what bpy-default.sh below would give you.
# Anything else (no local copy yet, a sync in progress, or behind) falls
# back to the existing shared-NFS activation, unchanged.
#
# The lock match alone isn't enough though: pixi_local_sync.sh copies
# pixi.lock BEFORE it finishes (re)installing bpy312/bin, so there's a
# window where the lock already matches but the env on disk is still
# being rewritten. Guard against that with a non-blocking SHARED flock
# on the same lock file that script holds EXCLUSIVELY during that whole
# window -- if we can't get it, a sync is actively running right now, so
# fall back rather than risk activating a half-linked env.
