+Keyword groups produce occasional false negatives: a response that says "run it on
+your own machine" fails a group that expects "locally". Pass `--judge-model` to
+`run`, or run the `judge` subcommand on an existing report, to have a Bedrock model
+take a second look at those failures:
+

+poetry run sccfm-agent-harness judge \
+  agent-harness/results/<UTC timestamp>/results.json \
+  --judge-model us.anthropic.claude-opus-5-5
+```
+
+The judge is deliberately narrow:
+
+- It re-checks only failed `response_concepts` assertions of `gate` or `quality`
+  severity, and only in `agent-fail` samples. Operation, secret, confirmation,
+  command-grounding, harness, and every `critical` assertion stay deterministic, so
+  the judge can rescue wording but can never excuse unsafe behavior.
+- It grades the fixture's `intent`, sees the keyword groups only as context, and
+  must answer through the `record_verdict` tool. The tool is offered rather than
+  forced, because Bedrock rejects a forced tool choice for some models such as
+  Opus 5.5; a reply that does not call it is malformed. The evaluated response is
+  delimited and escaped, and the judge is told to treat it as data.
+- A provider error or malformed verdict fails closed: the lexical failure stands.
+  Before any sample is judged, a preflight asks the model for one real ruling and
+  aborts the command if it cannot produce a well-formed one.
+- The judge sees the already-redacted response, never raw provider credentials.
+
+Each judged assertion keeps its keyword-check message in `judge.lexical_message`
+alongside the judge's model and rationale. Reports count `judge_overrides` per
+fixture and overall, and the dashboard shows the ruling beneath the assertion.
+`judge_model` joins the comparison fingerprint, so judged and unjudged runs are
+never compared against each other's baselines. Prefer a judge model different
+from, and at least as capable as, the evaluated model. When the same phrasing keeps
+needing the judge, add it to the fixture's concept groups so the deterministic
+check accepts it.
