name: DoD — End-to-end Sovereign demo (operator-gated)

# Closes Group M (#149-#157) — manual_dispatch ONLY because each run
# costs real Hetzner CX/CPX minutes. NEVER on push, NEVER on pull_request:
# the test scaffolding ships green via t.Skip() when HETZNER_TEST_TOKEN
# is absent (see tests/dod/dod_test.go::TestDoD_HarnessSkipsWithoutToken),
# so the ordinary build-and-test pipeline already covers the structural
# pass. Real provisioning is the operator's call, run from this workflow.
#
# Per docs/INVIOLABLE-PRINCIPLES.md #2 ("never compromise from quality"):
# this workflow runs the test against the real Hetzner test project. It
# does NOT build images — image builds are the catalyst-build workflow's
# job, per CLAUDE.md Rule 4a ("GitHub Actions is the only build path").
# Here we only TEST against an already-deployed catalyst-api SHA.
#
# The reported SBOM + cosign signature reference the catalyst-api image
# SHA captured by tests/dod/dod_test.go from the deployment response, so
# the operator can prove "this DoD run hit the same SHA the rest of the
# stack is running on" — closing the loop on docs/INVIOLABLE-PRINCIPLES.md
# #7 ("DoD E2E 2-pass GREEN on the current deployed SHA is the ONLY
# valid proof of done").
