[0.2.0] - 2026-07-03

The governance-first release. CodeRail now leads with the North-Star Kernel and
ships as installable plugins for Claude Code and Codex.

Added

  • K0 North-Star Kernel — every coding action must map to the current Outcome,
    Current Bet, Invariants, or Current Slice in docs/NORTH_STAR.md.
  • docs/NORTH_STAR.md as the first-class, persistent direction anchor
    (target ≤ 100 lines).
  • /align skill — intent-level check (L0–L5) before coding; produces a
    North-Star Check and a task-contract candidate.
  • /drift-check skill — detects goal drift, orphan tasks, and documentation
    rot across NORTH_STAR, TASKS, HANDOFF, and DECISIONS.
  • Plugin manifests for Claude Code (.claude-plugin/) and Codex
    (.codex-plugin/), with skills under skills/.
  • Project template (project-template/) — AGENTS.md, CLAUDE.md, and the
    docs/ set, plus TASK_GRAPH.md and METRICS.md for Standard mode.
  • Installer script scripts/init_project.py with --mode lite|standard,
    copies templates without overwriting non-empty files.
  • scripts/doctor.py — read-only governance health report.
  • scripts/drift_check.py — static drift detection across docs.
  • Adoption Gate (references/ADOPTION_GATE.md) — five criteria any new skill
    or workflow must pass to enter the default set.
  • Four adoption tiers: Lite, Standard, Team, Enterprise (references/MODES.md).
  • Validation hierarchy reference: executable harness > static acceptance >
    tool-native enforcement > human review > agent self-check (soft gate only).
  • SECURITY.md, CONTRIBUTING.md, and CODE_OF_CONDUCT.md.

Changed

  • Converted the previous standalone document bundle into a plugin-compatible
    package with a clear skills/ + project-template/ + references/ layout.
  • Renamed the project to CodeRail (previously an internal codename).

Removed

  • All research-origin terminology from runtime files. The structure test
    (tests/test_structure.py) now enforces engineering-only language.

Project metadata

  • Rewritten README.md with explicit positioning, audience, and a comparison
    section covering Superpowers, spec-kit/Kiro, and BMAD.
  • Public repository metadata (package.json, plugin manifests) point to
    github.com/HaipingShi/coderail.

Notes

  • Self-checks remain soft gates only. Harness, CI, permissions, hooks, and
    review remain the stronger validation layers (K3, K4).
  • No active hooks by default. examples/ contains sample hooks and
    permission configs that are default-off until you review and enable them.
