Phase 2 lesson from F2-3 (n8n install Playwright flake on net::ERR_NETWORK_CHANGED): every
install overlay that does page.goto needs the same try/except PlaywrightError + status retry.
Centralize in runner/harness/browser.py::goto_with_retry; apply to ALL install overlays.
- runner/harness/browser.py: shared helper. Polls page.goto until status in accept_statuses;
catches PlaywrightError (net::ERR_*) as a retryable signal, not a failure. Raises AssertionError
with last_status + last_err diagnostic only on deadline expiry.
- tests/custom-html/test_install.py: now uses goto_with_retry (200 only, wait_until=load).
- tests/custom-html/playwright/test_browser_smoke.py: same.
- tests/n8n/test_install.py: replaced inline retry loop with goto_with_retry (200, 304).
- tests/keycloak/test_install.py: goto_with_retry for admin console (200, 302, 303; 45s goto).
- tests/cryptpad/test_install.py: goto_with_retry (200, 304; 60s goto, wait_until=load).
- tests/lasuite-docs/test_install.py: goto_with_retry (200, 301, 302; 60s goto).
Cold-verifiable: ssh cc-ci 'RECIPE=custom-html cc-ci-run runner/run_recipe_ci.py'
all 5 stages PASS (including the install overlay that flaked in the deps_smoke run),
deploy-count=1, head_ref=8a026066==chaos-version=8a026066 (HC1 non-vacuous).

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.

- tests/n8n/PARITY.md: parity table (health_check ported) + 2 recipe-specific
functional tests with rationale + data-integrity section pointing to
Phase-1d/1e lifecycle overlays.
- tests/n8n/functional/test_health_check.py: parity port of
recipe-info/n8n/tests/health_check.py — SOURCE comment.
- tests/n8n/functional/test_rest_settings.py: NEW recipe-specific — polls
/rest/settings until response is application/json (not the 'n8n is starting
up' SPA placeholder); asserts known n8n public-settings keys
(userManagement/defaultLocale/authCookie) in the 'data' envelope. Proves the
editor SPA's primary API contract is intact.
- tests/n8n/functional/test_login_state.py: NEW recipe-specific — polls
/rest/login until response is JSON; proves the user-management/auth subsystem
initialized on top of the public-settings layer.
- tests/n8n/test_install.py: install overlay's Playwright now polls page.goto
until status==200 (n8n's / route can return 404 briefly while the SPA route
registers on top of /healthz=200). Bounded poll, no bare sleep, raise on
persistent failure — same robustness pattern as Phase-1e exec_in_app.
Cold-verifiable on cc-ci (log /root/ccci-q1-n8n-r3.log):
RECIPE=n8n cc-ci-run runner/run_recipe_ci.py
all 5 stages PASS, deploy-count=1, head_ref=63dd3e0f==chaos-version=63dd3e0f,
version 3.1.0+2.9.4 -> 3.2.0+2.20.6 (HC1 non-vacuous), 5 lifecycle assertions
+ 3 custom-stage assertions all PASS.

Mechanical port to the assertion-only contract (no softened/skipped assertions): install uses
live_app + generic.assert_serving (extend) + the recipe's http/playwright/api checks; upgrade seeds
its data marker then generic.do_upgrade + asserts survival; backup/restore split into test_backup.py
(seed->do_backup->mutate) + new test_restore.py (do_restore->assert original). Recipe-specifics
preserved verbatim (keycloak realm+admin-console+kc_admin, matrix/lasuite db-service psql markers,
cryptpad/n8n volume markers). No recipe now double-deploys under the deploy-once orchestrator.
