Tools & Instruments
Interactive diagnostics, data instruments, and design prototypes. These tools operationalise ACI analytical frameworks against live or reference data. They are not publications — they are instruments.
AFS Instruments — Companion to WP-012
AFS Live
v1.5 · 2026
AFS Core — Live Grid Monitor
Real-time AFS StateEngine with Fingrid + ECB integration
Live diagnostic instrument applying the AFS StateEngine (v1.5) to current Finnish grid data. Connects to Fingrid Open Data API (production DS 192, consumption DS 193, surplus DS 198, wind DS 181, spot price DS 105) and ECB yield curve API (Finnish 10Y bond, iBase parameter). Computes PDI, SBM, zone classification, and T-t-T in real time. Includes RKOM intervention simulator and plain-language tilannearvio panel. Requires Fingrid proxy configuration.

WP-012
Scenario Engine
MESA Transition Scenario Engine
AFS trajectory simulator 2026–2035
Interactive scenario engine for the WP-012 MESA Transition Pathway analysis. Applies linear parameter interpolation across four scenarios (S0 Inertia → S3 Full Integration) and displays zone trajectories in AFS state space. Allows readers to adjust endpoint parameters and observe the PDI/SBM trajectories and zone transition years that result. Uses the identical AFS StateEngine as the live monitor. Companion to WP-012 §3–§5.

Validator
WP-001 Calibration Validator
Duration adequacy parameter testing — Fingrid historical data 2015–2024
Interactive calibration tool for WP-001 duration adequacy parameters. Fetches Fingrid historical wind and consumption data (DS 181, DS 193) via proxy and validates AR(1) residuals, low-wind episode statistics, and demand persistence parameters against the WP-001 calibration set. Provides the empirical baseline for TN-006 εₜ estimation. Requires Fingrid proxy configuration.

Note on tool status
Live data tools require a Fingrid Open Data API key, available free at data.fingrid.fi, served via a CORS-compatible proxy. The AFS Live Monitor and WP-001 Calibration Validator use a dedicated proxy endpoint; the ECB yield curve API (iBase parameter) is fetched directly without a proxy. Dataset IDs should be verified before deployment as Fingrid has changed identifiers historically. Design prototypes are not functional and are provided for reference only. Tools in this section are experimental and subject to change independently of the publication versioning cycle.
