# Regression: config/defaults.conf must be installed to the canonical share path
# and both consumers (channel-render-lib.sh, oxpulse-channels-health-report.sh)
# must agree on that path.
#
# Bug 8 (deferred from Phase 5.5): Two consumers expect defaults.conf at divergent
# paths:
#   channel-render-lib.sh:30  → /usr/local/share/oxpulse-partner-edge/config/defaults.conf
#   oxpulse-channels-health-report.sh:26 → /etc/oxpulse-partner-edge/config/defaults.conf
# Neither path is populated by any install lib.  On a live install, channel-render-lib.sh
# silently skips the source (else branch: no-op); health-reporter silently misses defaults.
#
# Fix: install to canonical path /usr/local/share/oxpulse-partner-edge/config/defaults.conf
# via lib/install-systemd.sh, and unify health-reporter to the same path.
