Vigil API — Changelog

Stability policy: /v1 endpoints are additive-only — existing fields are never renamed, retyped, or removed within v1. Breaking changes ship as /v2 with at least 90 days of parallel operation, announced on this page.

2026-07-03

Public endpoints (/v1/performance, /v1/status) now serve Cache-Control: public, max-age=300; server-side response caching added.
Equity feature-drift monitoring corrected to compute on the model training interval (hourly); false "stale feed" flags eliminated.

2026-07-02

New fields on /v1/performance and /v1/status: base_rate_24h, edge_24h_pp, accuracy_24h_acting, accuracy_12h_acting, accuracy_4h_acting — accuracy is now published against the unconditional base rate.
Embeddable live badge at /badge.svg.
Public delayed regime feed launched (Telegram: @vigilsignals).

2026-06-30

Regime verdicts are now volatility-regime-conditional: risk-off calls are emitted only in regimes with statistically stable, temporally validated edge; low-edge conditions return NEUTRAL.
Track-record methodology section published (base rates, edge decomposition, selectivity rationale).

2026-06-29

Recovery-phase labels re-derived from validated deployment-score bands (falling-knife mislabeling fixed).
