B6 false-FAILed because it built the project registry from the
launcher process-env via a host-path hack (sys.path.insert +
importlib.reload), not from the running staging instance. Run from the
host, ORCH_PROJECTS_JSON is unset -> default ET+ORCH registry -> false
FAIL -> spurious deploy-staging -> development rollback.
Variant (v) per ADR-001: remove the host-path hack; canonically run the
suite INSIDE orchestrator-staging via docker exec so src.projects
resolves from /app (PYTHONPATH) with .env.staging. Verdict logic
extracted into pure _evaluate_b6(known) -> (passed, detail) +
_known_project_ids_from_registry() / _run_b6() with deterministic FAIL on
source unavailability. deployer.md and STAGING_CHECK.md updated to the
docker exec command. src/projects.py, .env* and checks A/B4/B5/C
untouched.
