GET /api/v1/signals/diff

Handler: app.signals.routes.get_signals_diff
Methods: GET

Description

Return only fields that changed beyond threshold since a reference row.

Two modes:

• ?from=YYYY-MM-DD — diff the latest row against the row for that date.
• ?days_back=N (default 1) — diff the latest row against the Nth prior row.

Thresholds are declared per-field in app/signals/config/diff_thresholds.json so the “what is material” definition is auditable. Fields use one of three comparison kinds: pct (relative), abs (absolute delta), or label (string inequality — used for regime / severity / energy_regime flips).
