# Contributor hub

Use this hub to change code or docs without breaking CE semantics.

Repository authority:
- `kristinebergs/calibrated_explanations` is the active development mirror.
- `Moffran/calibrated_explanations` is authoritative for releases, tags, PyPI publication, changelog, security advisories, and published docs.

## Core path

1. Read {doc}`plugin-contract`.
2. Use {doc}`extending/guides/index` for implementation workflows.
3. Run checks from {doc}`../foundations/governance/pr_guide` and
   {doc}`../foundations/governance/test_policy`.
4. Use {doc}`../standards/STD-004-documentation-audience-standard` for docs
   structure and semantics-layer requirements.

Contributor-facing semantics references:
- {doc}`../foundations/concepts/calibrated_interval_semantics`
- `docs/improvement/adrs/ADR-021-calibrated-interval-semantics.md` (maintainer-only docs set)
- `docs/improvement/adrs/ADR-026-explanation-plugin-semantics.md` (maintainer-only docs set)
