# Nova CLI Action — composite action (REQ-326, NFR-11)
#
# Runs a Nova CLI command (`nova <command>`) in a consumer repository.
# Python 3.12 is pinned (REQ-326 AC3). The same action.yml is discovered
# by both the production forge (GitHub Actions) and the dev forge
# (act_runner) via the shared .github/actions/nova-cli/ path — there is
# no separate dev-forge action file. Consumers reference it via a
# versioned tag pin:
#
#   uses: <org>/<repo>/.github/actions/nova-cli@v1.28
#
# Wheel index selection (CodeArtifact default + fallback):
#   - CodeArtifact mode: set the NOVA_CODEARTIFACT_DOMAIN repository
#     secret/env. The action runs
#     `aws codeartifact login --tool pip --domain $NOVA_CODEARTIFACT_DOMAIN
#     --repository nova-pypi` before `pip install nova`.
#   - Fallback mode: leave NOVA_CODEARTIFACT_DOMAIN unset and provide
#     NOVA_WHEEL_INDEX env pointing at any PEP 503 simple index (a
#     private package registry). The action runs
#     `pip install --index-url $NOVA_WHEEL_INDEX nova==<version>`.
#   See docs/codeartifact-provisioning.md for the index shape.
#
# Byte-identical cross-platform verification (NFR-11, REQ-326 AC2):
#   the full byte-identical test runs as a CI matrix job on the
#   production forge (ubuntu-latest) + the dev forge (act_runner) with
#   identical inputs, asserting same stdout + exit code. That matrix is
#   not reproducible in a unit test; the structural invariants (valid
#   YAML, python 3.12 pin, install + run steps present) are asserted by
#   tests/test_forge_action_byte_identical.py.
