Full changelog

ContextLevy v2.4.0

Added

Fallow dead-code analysis (npm run check:fallow) with project-specific configuration and CI coverage.
Mode presets: advisory (default), strict, minimal, and legacy for v2.3 behavior.
contextlevy init to scaffold contextlevy.config.yml and an optional GitHub workflow.
contextlevy check as the primary CLI command, with diff retained as an alias.
Category-aware gates with fail-on-categories, warn-only-categories, and comment-on-hygiene.
Review summary headlines, prioritized findings, and enriched CLI JSON metadata.
allowlist-paths as an alias for allow-paths.
Quick start documentation for local setup, modes, allowlists, and hooks.

Changed

Default behavior now uses advisory mode: compact comments, no cost table, hygiene-aware comment posting, and agent-config alerts.
PR comments can post for hygiene categories or agent instruction changes below the token threshold.
Severity and compact findings now reduce false alarms for lockfile-only and small agent-config changes.
CI and npm run check now include Fallow alongside Biome, typecheck, and tests.
Internal parser, git, token, and auth helpers no longer export unused implementation details.
Cost table copy now frames estimates as illustrative rather than billing-grade.

Notes for existing adopters

Set mode: legacy in contextlevy.config.yml to restore v2.3 defaults.
