# Phase 5.5 MAJOR 1 — hydrate/update/refresh fail-soft full wiring.
#
# The spec shipped render_channel_soft + CHANNELS_FAILED + compose-strip to
# install.sh in PR #186 but did NOT wire them into hydrate.sh / update.sh /
# oxpulse-partner-edge-refresh.sh. This test covers:
#
#   Case 1: lib/render-channel-lib.sh exists with render_channel_soft(), _in_array(),
#           CHANNELS_FAILED=(), and compose_strip_failed_channels()
#   Case 2: install.sh sources lib/render-channel-lib.sh (no longer defines inline)
#   Case 3: hydrate.sh sources lib/render-channel-lib.sh and uses render_channel_soft
#           for xray and naive channel renders
#   Case 4: update.sh sources lib/render-channel-lib.sh and uses render_channel_soft
#           for channel renders
#   Case 5: oxpulse-partner-edge-refresh.sh sources lib/render-channel-lib.sh and
#           uses render_channel_soft for channels_version re-render
#   Case 6: lib/install-systemd.sh installs lib/render-channel-lib.sh to PREFIX_SBIN
#   Case 7: release.yml stages lib/render-channel-lib.sh as a release asset
#
#   Behavioral Case 8: render_channel_soft() from lib/render-channel-lib.sh
#           behaves identically to the original in install.sh (appends to CHANNELS_FAILED)
