NFI Backtest Engine v1.3.0-rc.1

NFI Backtest Engine v1.3.0

v1.3.0 makes rapidly changing NFI revisions usable without weakening exactness.

Highlights

• Reports every Native-to-official Freqtrade fallback before execution and keeps the
  blocked Native evidence immutable.
• Compiles supported Signal, tag, Grind, protection, leverage, and trade-state
  behavior from strategy source into generic IR rather than adding version-specific
  runtime branches.
• Checks upstream NFI every four hours with separate Spot and Futures results,
  targeted official/Native verification, append-only evidence, and deduplicated
  semantic and infrastructure issues.
• Runs Futures coverage discovery separately under a bounded, resumable policy. An
  exact, size-limited fixture may open a Draft PR, but automation never approves or
  merges it.
• Keeps raw candles, caches, and traces out of permanent automation branches and
  preserves compact discovery evidence under the normal safe-cleanup lifecycle.

Certification boundary

This is a product release, not a new combined Full X7 certification. The published
five-year Spot certificate remains bound to v1.0.0 and the published five-year
Futures certificate remains bound to v1.1.0. v1.3.0 wheels are built once, exercised
with exact Spot and Futures fixtures on Linux, Windows, and macOS, checksum-sealed,
and promoted from RC to stable without rebuilding.

Upgrade

Run the normal installer again. It selects the v1.3.0 wheel for the current supported
platform, verifies the published SHA-256 digest, and replaces the isolated nfi-bte
tool installation.
