v1.2.13 June 2026 — Realistic outcomes

Corrected an artifact where the index recorded a ~97% chicken-out rate with zero follow-throughs. Four fixes (migration v25):

v1.2.12 June 2026 — Deadline-pressure window reconciliation

Closed a limbo gap where deadline-after-threat events could drop out of both the live-pressure and settled index between their threat-aging and finalization anchors. Live pressure now runs from the stated deadline to deadline + 90 days, the exact complement of finalization.

v1.2.11 June 2026 — Event lifecycle finalization

Every event now terminates as a TACO or a facilitation rather than tracking indefinitely. Historical backfill finalizes immediately instead of parking in monitoring. Migration v24 makes calibration_locked consistent across both seed loaders.

v1.2.10 June 2026 — Live deadline pressure

Overdue, unresolved threats now build a provisional live_pressure_score each cycle, so an unmet deadline visibly accrues pressure over time. The settled index value is unchanged; a new index.live_value folds overdue pressure in so the headline can move in real time.

v1.2.7 – v1.2.9 June 2026 — USTR Section 301 coverage + efficiency

Section 301 USTR actions publish as Federal Register NOTICE documents (not presidential documents) and were previously invisible to the index. The pipeline now ingests USTR notices (threat_source='ustr_notice'), with a notice-window backfill fix (v1.2.9) and a calibration-catalogue lock (v1.2.8) that freezes hand-curated benchmarks so their values never drift.

v1.2.4 – v1.2.6 May–June 2026 — Live data + proclamation ingestion

The dashboard now reads live data from GET /api/v1/snapshot, decoupling published-data freshness from deployments. Presidential proclamations (Section 232 / reciprocal tariffs) are now classified into events. Academic-only replication datasets were removed in favor of freely-citable published constants.

v1.2.0 – v1.2.3 May 2026 — Statutory authority + economic verification

Added the statutory_authority field (IEEPA, Section 301/232/122, etc.), PACER PCL as an automated court fallback, and BEA PCE pass-through series for cross-validation against the Yale Budget Lab Tariff Tracker.

v1.1.0 May 2026 — Economic impact methodology

Integrated the four-group economic-impact methodology, formalized the six-dimension behavioral scoring framework (weights 30/20/15/15/10/10), added the rolling 30-day exponentially-weighted index (~23-day half-life), and published the REST API specification.

v1.0.0 May 2026 — Initial public release

Four-criterion event definition (specificity, actionability, measurability, materiality), four-domain taxonomy (Trade, Foreign Policy, Domestic, Rhetorical), five-stage event lifecycle, and AI-assisted detection with human-in-the-loop review.
