tests/test_forge_action_byte_identical.py — 15 tests asserting the
structural invariants of the nova cli-action composite action
(.github/actions/nova-cli/action.yml). The action is consumed by both
the production forge + the dev forge via the same file path, so a
single source under test guarantees both platforms consume the same
bytes (the byte-identical requirement, NFR-11).
Structural invariants covered (the unit-testable subset):
(a) action.yml is valid YAML
(b) name present + non-empty
(c) inputs.command required: true
(d) inputs.contract / mode / version exist with documented defaults
(.nova/contract.yml, "", "latest") and are not required
(e) runs.using == "composite"
(f) a setup-python@v5 step pins python-version "3.12" (REQ-326 AC3)
(g) an install step installs `nova` via both CodeArtifact
(codeartifact login --tool pip) + fallback (--index-url) paths,
parameterised by inputs.version
(h) a run step executes `nova ${{ inputs.command }}` with
NOVA_CLIENT_MODE (from inputs.mode) + NOVA_CONTRACT (from
inputs.contract) env forwarded
NFR-11 byte-identical source guard: the action.yml must not embed
forge-specific hostnames / org names / the dev-forge or consumer-mirror
names, and the install path must be selected by env var at runtime
(NOT a forge-identity conditional) — so the file stays byte-identical
across forges. Both asserted.
The full byte-identical cross-platform verification (NFR-11,
REQ-326 AC2) — running the action with identical inputs on a
production-forge ubuntu-latest runner + a dev-forge act_runner and
asserting identical stdout + exit code — is a CI matrix job, not a
unit test. It cannot be reproduced in-process (depends on two external
runner environments). Documented in the module docstring + the
action.yml header; the CI matrix job is defined out-of-band.
All 15 tests pass. No regressions in tests/test_pipeline_contract.py,
tests/test_deploy_workflow_env_input.py, tests/test_rotate_key_workflow.py
(77 passed). tests/test_no_forge_mentions.py passes (the test file +
action.yml + publish.yml are clean of forge-specific strings).
