+## Provisional LLM-only pipeline smoke
+
+Before human adjudication is complete, unanimous two-pass LLM suggestions can
+be materialized into the review-file schema for a pipeline smoke test:
+
+```bash
+python3 materialize_provisional_llm_reviews.py \
+  --events reports/easycom_entry_int_session{1,2,3,4}_v14/easycom_eot_int_deepseek_official*.jsonl \
+  --output reports/easycom_entry_int_sessions1_4_v14/easycom_eot_int_provisional_llm_reviews.jsonl \
+  --acknowledge-provisional-llm-auto-accept
+```
+
+The converter skips pass disagreements, pending API failures, and candidates
+without an LLM suggestion. It writes JSONL, CSV, and a summary JSON. Every
+materialized row carries `review_source=PROVISIONAL_LLM_AUTO_ACCEPT` and
+`human_reviewed=false`; the nested `human_status=REVIEWED` value exists only
+for review-schema compatibility and must never be described as human review.
+The discouraged `--include-nonunanimous` option is available only for debugging
+the fallback path.
+
+The evaluator rejects these rows by default. A provisional run requires an
+explicit opt-in and marks its output protocol and semantic scope accordingly:
+
+```bash
+python3 evaluate_annotated_floor_events.py \
+  --reviews reports/easycom_entry_int_sessions1_4_v14/easycom_eot_int_provisional_llm_reviews.jsonl \
+  --run egospeak=results/egospeak_miniroada_floor_eval \
+  --sessions Session_4 \
+  --allow-provisional-llm-reviews \
+  --print-event-examples 5 \
+  --output results/easycom_egospeak_event_smoke/session4_summary.json
+```
+
+This output is suitable for alignment debugging and preliminary analysis, not
+for a manuscript claim of human-adjudicated ground truth. Official test
+Sessions 1--3 still require disjoint training-side calibration unless the
+separate exploratory in-sample override is used.
