#!/usr/bin/env python3
"""query.py — token-cheap module selector over modules.json.

An agent uses this to find exactly the modules it must act on WITHOUT reading the
whole state file. Filter by grade/score level, by smell tag, by finding severity,
by band/coupling, or by staleness; emit just ids, paths, a compact table, the
findings, or filtered JSON.

Examples:
  # all C-and-below modules → just their ids (pipe into a fix loop)
  python query.py --state s.json --max-grade C --format ids
  # modules with a dual-format problem, worst first, as a table
  python query.py --state s.json --tag dual-format
  # the file globs to read for every module that has a HIGH finding
  python query.py --state s.json --sev HIGH --format paths
  # the actual findings to fix for one tag, as text
  python query.py --state s.json --tag glue --format findings
  # what needs re-auditing (stale or never scored)
  python query.py --state s.json --needs-audit --format ids

Filters combine with AND. --tag may be repeated (ANY by default, --match-all for AND).
Stdlib only.
