Strips <system-reminder>/date/uuid/tmp-path so one fixture replays across days and from both the browser and direct-POST paths; a miss raises loudly (no silent divergence). - Recording is record-through-browser (scripts/record_gateway.py + build_fixture_from_jsonl.py + frontend/tests/e2e-record): a real run is driven through the real frontend so captured inputs match exactly what the browser sends; fixtures contain no API key. - Layer 1 — backend golden (tests/test_replay_golden.py): replay through the real gateway, assert the SSE event sequence == committed golden. - Layer 2 — full-stack render (frontend/tests/e2e-real-backend): real Next.js + real gateway (replay model) + Chromium; assert the replayed auto-title and follow-up suggestions render. DOM assertions are the gate; visual regression is a local dev gate (CI uploads the render as an artifact). - CI (.github/workflows/replay-e2e.yml): both layers, triggered on EITHER side of the contract (frontend/** or backend gateway/harness/fixtures). * test(e2e): multi-run render-order cross-stack scenario (#3352) Guards the dangerous front-back class where a backend ordering change silently breaks a frontend assumption while both sides' unit tests stay green. Reproduces issue #3352: backend list_by_thread returns runs newest-first (#2932) and the frontend prepended per-run pages, inverting chronological order once the checkpoint no longer held the older messages. - tests/seed_runs_router.py: test-only seeder, mounted on the replay gateway only when DEERFLOW_ENABLE_TEST_SEED=1 (never in the production app). Seeds a thread with >=2 runs + per-run message events and no checkpoint -- the #3352 precondition -- so the frontend per-run reload path is the sole source of truth and the prepend inversion is observable. - frontend/tests/e2e-real-backend/multi-run-order.spec.ts: drives the real frontend against the real gateway, asserts the first run renders above the second. Reverting the #3354 fix turns it red. - replay-e2e.yml: trigger on the new replay test-infra paths. - docs: REPLAY_E2E.md cross-stack scenario section. * test(e2e): address Copilot review on the replay harness - Fix stale recorder references (scripts/record_traces.py -> scripts/record_gateway.py + scripts/build_fixture_from_jsonl.py) in replay_provider.py, test_replay_golden.py, _replay_fixture.py. - MODE_CONTEXT['ultra']: thinking_enabled False -> True, mirroring the frontend's `context.mode !== 'flash'` (hooks.ts). It did not affect the hashed input (Layer 1 golden still green), but the table now matches the real frontend context it claims to mirror. - replay_provider.py docstring: stop claiming memory is recorded-enabled; the replay config disables memory/summarization for determinism (title stays, as an in-graph deterministic call). - record_gateway.py / run_replay_gateway.py: override DEER_FLOW_HOME instead of setdefault, so an outer value can't leak into the hermetic harness. - record_gateway.py: clear error when DEERFLOW_RECORD_OUT is unset (was a bare KeyError). - playwright.record.config.ts: forward OPENAI_*/DEERFLOW_RECORD_OUT only when set, so the gateway raises a clear 'missing env' error instead of getting ''. * test(e2e): address Copilot review round 2 - seed_runs_router.py: constrain SeedMessage.role to Literal['human','ai'] so a bad value is a clean 422 at the boundary instead of a 500 (KeyError on _EVENT_TYPE). - record-write-read-file.spec.ts: waitForCaptureStable now throws on timeout instead of returning the last count, so a truncated/partial recording can't pass silently. - real-backend-render.spec.ts: guard the suggestions JSON.parse; a bracket-prefixed non-JSON turn falls back to '' so the existing not.toBe('') assertion fails clearly instead of a generic parse throw.	2026-06-08 12:35:03 +08:00
