F2-4 (P3/§4.3 floor — gate-blocker on Q1):
tests/n8n/functional/test_workflow_roundtrip.py: plan §4.3 prescribed test.
POST /rest/owner/setup with class-B run-scoped owner email+password (plan
§4.4-B); capture auth cookie; POST /rest/workflows with a minimal Manual-
Trigger workflow; GET /rest/workflows/<id>; assert the round-trip (id,
name, nodes payload all preserved). Removes the prohibited 'needs owner
setup' excuse; exercises n8n's defining persistence + retrieval surface.
F2-3 (cold-run flake on install):
tests/n8n/test_install.py: wrap page.goto(...) in try/except PlaywrightError
inside the retry loop so net::ERR_* / connection resets trigger a retry
instead of an immediate test failure. Same pattern as F1e-1's exec_in_app
poll+raise hardening.
PARITY.md updated: 3 recipe-specific tests now listed; workflow_roundtrip
called out as the plan §4.3 prescribed create+read-back; rationale for keeping
test_rest_settings / test_login_state retained.
Cold-verifiable on cc-ci (log /root/ccci-q1-n8n-r4.log):
RECIPE=n8n cc-ci-run runner/run_recipe_ci.py
all 5 stages PASS, deploy-count=1, head_ref=63dd3e0f==chaos-version=63dd3e0f.
Custom tier ran 4 PASS: health_check, login_state, rest_settings, AND the
new workflow_create_and_read_back.
