# UV Suite helper: list an artifact across sessions for "prefer current, allow prior".
# Usage: uv-out-collect.sh <relative-glob>      e.g.  specs/*.md   or   map-codebase.md
#
# Prints tab-separated lines, current session first, then other sessions
# (newest session first), then legacy flat uv-out/ files:
#   CURRENT  <session-name>  <YYYY-MM-DD>  <path>
#   PRIOR    <session-name>  <YYYY-MM-DD>  <path>
#   LEGACY   -               <YYYY-MM-DD>  <path>
# A skill shows these and asks the user which to use (default: the CURRENT one,
# else the newest PRIOR).
