# Annotate a round's delivered reports in one call, so the foreman gates them together.
#
# The foreman reads every report body in full before gating
# (skills/herdr-foreman/references/team-operation.md Reports), and that does not change. What
# changes is the turn structure: one call annotates every report, then the foreman
# reads them all with their verdicts in hand and gates them in one turn, instead
# of spending a full-context turn per report (#482).
#
# A label never replaces the read and never approves. A failed one never blocks
# gating: the report lands in `unannotated` with the reason, and the foreman
# reads it exactly as it always has. The only effect a label can have is the
# gate `foreman report-gate-record` derives from it, which adds friction and
# never removes it (foreman/report_gates.py).
#
# Usage: classify-reports.sh [--agent jev|codex|claude|grok] <report>...

# Output contract (rules/script-delegation.md -- structured stdout):
#   stdout: one JSON object --
#     {"schema_version": 2, "agent": "<kind>" | "default",
#      "labels": [<classify-report.sh label>, ...],
#      "unannotated": [{"report": "<path>", "reason": "<diagnostic>"}, ...]}
#   `agent` is the adapter requested, "default" for Jev; each label names the
#   adapter that answered. A report Jev could not label is in `unannotated`
#   with the reason, and is read in full.
#   stderr: per-report progress and every unannotated report.
#
# Exit 0 whenever the arguments were valid, including when some or every
# annotation failed -- those are reported, not fatal. Exit 2 on a usage error.
#
# Each report is one model call against the chosen vendor's quota.
