DEJM Crisis Detection Pipeline

Phase 1 ingestion status. Narrative volume and tone series per case, with ground-truth trigger dates marked. TSI computation and signal detection are not implemented — they depend on open items in the systems analysis document that fix the algorithm, the lead-time threshold and the Ts weighting.

Series are ingested from the GDELT DOC 2.0 API and stored with full provenance — endpoint, parameters and response digest per call. Keyword sets shown as provisional are not yet fixed, so these series are indicative and not paper-grade. See README.md for verified deviations from the specification.
