Council review — 🔴 REDThanks for #906 and this PR. The report is careful: a benign one-line prompt, manual Chrome as a control on the same profile, and a typing-speed hypothesis you tested and ruled out rather than kept quiet about. That is the standard we ask for. The review below is about what the diff contains, not about whether the problem is real — it is. 1. The stealth change is not in the PRThe body says 2. We measured what stealth would change — it is not a tellgflow's generation context already drops Identical in both arms:
None is an automation tell, and two make the browser less consistent. On our machine stealth cannot explain a pass/fail flip. Single machine, Chrome 153, one account — it does not say your account is not refused; it says the fingerprint is probably not why. The confound we cannot rule out from here is the launcher.
3. The branch is based on v0.75.0It is one commit on 4. The refusal-card scrape repeats #873's blocked mechanism
These are the #873 re-review items. #873's latest revision is actually the stronger of the two (baseline of existing cards, redaction, tests), so two PRs now carry competing versions of one fix. 5. Smaller
What happens nextTo stop you rebasing two PRs against a moving file, we will take the refusal-card fix over: one PR combining #873 and this one, detecting the card by its tile structure and scoping it to the tile this submit created, with a non-prompt remediation for the unusual-activity case. You will be credited in the CHANGELOG as the author of the diagnosis. When it lands, #873 and this PR's scrape are superseded. The stealth question stays open on #906 — the two measurements above are what would move it. If they show the fingerprint does matter, we would want the one property that does it rather than a library that spoofs a GPU. |

…froliva#906, ffroliva#873) flow.google.com answers a refused submit with HTTP 200 and a batchexecute error envelope: a null payload, the gRPC status in slot 5 and Google's ErrorInfo reason inside it. parse_frames kept only frames with a string payload, so every caller saw an empty reply: the video path waited out a retryable 60 s TransportTimeoutError and the image path raised WireFormatError("no ogiZ0b frame"), while Flow's grid showed "We noticed some unusual activity". batchexecute.rpc_errors now returns the envelopes parse_frames skips, and both submit observers map a REASON to a class: PUBLIC_ERROR_UNUSUAL_ACTIVITY to WafRejectionError (the labs path's class for the same reason, retryable flag preserved) and the content-safety reasons to ContentPolicyError. A bare status with no reason is not a refusal - the ffroliva#723 queued entity submit replies [5] - so it keeps today's behaviour. Measured, not inferred: a submit with its reCAPTCHA token corrupted in flight is refused with that envelope; an aborted submit gets no reply but renders the identical <flow-error-tile>, which is why the grid card cannot be the signal. New e2e (opt-in GFLOW_CLI_E2E_RUN_REFUSAL=1) provokes a real refusal and passed on a probe profile. Diagnosed by @stgmt in ffroliva#873 and ffroliva#906. Supersedes ffroliva#873 and the refusal-card half of ffroliva#907.
… context (ffroliva#906) Measures what `Stealth().apply_stealth_async` changes on top of gflow's own generation context on flow.google.com ($0, nothing submitted). webdriver, automation globals, UA brands and sec-ch-ua headers are identical in both arms; only navigator.languages, a notifications permission state and the WebGL vendor move, and the last two become less consistent. So stealth cannot explain the pass/fail flip reported in ffroliva#906 on this machine; the contributor's isolated-desktop launcher is the leading unmeasured confound. Memory: records ffroliva#907 as the third reintroduction of the body-wide refusal-card text scan, and that "unusual activity" is not a content verdict and does not justify a stealth dependency.

Replying to your council review — the force-push above is the rework it asked for. 1 & 3. Rebased onto current 2. The launcher confound — tested. You were right that Supporting changes that fell out of the live run:
4. Refusal-card half dropped. #909 reads the refusal from the wire envelope and supersedes the DOM scrape; this branch no longer carries 5. Smaller items addressed: CHANGELOG entry added; tests exist and pass; no fork-CI blocker stated on our side — if a workflow is required on the head, say which job and I will trigger it. |

Kill the spawned Chrome if the CDP attach or context setup fails.
chrome_proc is wrapped in _CdpContext only on the last line. If connect_over_cdp, browser.new_context(), or ctx.pages raises, no caller holds chrome_proc. client._close_browser_resources never sees it, and _pw.stop() does not kill a process the driver did not launch. The orphaned Chrome keeps the profile lock, and the next run fails with a locked profile. Wrap these lines in a try block and kill chrome_proc on BaseException.

Do not retry a submit click after an ambiguous failure.
Playwright can throw after it dispatches a click, including while it waits for navigation or if the target detaches. _human_click then clicks again. If the submit control remains actionable, GFLOW_HUMAN=1 can send two credit-spending requests. Remove the unconditional fallback for submit clicks.

Stop image submission when reCAPTCHA readiness expires.
If grecaptcha.enterprise is still unavailable after 15 seconds, this handler discards the failure and clicks Generate. The changed code identifies an absent mint surface as a cause of PUBLIC_ERROR_UNUSUAL_ACTIVITY. Report a pre-submit readiness failure instead of sending a request in that state. Do not suppress page-closure errors as readiness timeouts.

…com WAF fingerprinting On the migrated host (flow.google.com), patchright's bundled browser carries automation fingerprints that Flow's WAF keys on, so automated submits get PUBLIC_ERROR_UNUSUAL_ACTIVITY even with valid cookies. - GFLOW_CLI_CDP_LAUNCH=1: spawn the installed chrome.exe with a free --remote-debugging-port and attach patchright over CDP instead of launch_persistent_context. Requires GFLOW_CLI_BROWSER_ENGINE=patchright; on any other engine it raises ConfigurationError rather than silently starting the wrong browser. - api/client.py: route _launch_persistent_context through cdp_launch when the env flag is set; drop --disable-blink-features=AutomationControlled from the stock args (it is itself a fingerprint). - transports/ui_automation.py + experimental/evaluate_fetch.py: same flag removal plus ignore_default_args for --enable-automation/--no-sandbox. - migrated_composer.py: replace filter(has=mat-icon-ligature) with XPath descendant selectors — has= runs a page-side evaluate that resolves to zero elements under patchright. Add a scoped-radios retry loop to _open_pane for Angular remounts, model the blocking-overlays XPath, and add GFLOW_HUMAN/GFLOW_HUMAN_TYPE humanized prompt typing plus humanized video/image submit clicks. - Keep upstream ffroliva#909's WafRejectionError wire-read refusal detection; the refusal-card scrape half of this branch is superseded and removed. - tests: extend the FakePage/FakeLocator test double for the new XPath selectors, wait_for_function, and mouse so the migrated suite still exercises the real driver paths.

Clean up Chrome when CDP attachment fails.
launch_via_cdp() starts Chrome before calling connect_over_cdp(). If attachment raises, _CdpContext.close() is never available, so the Chrome process can remain running and retain the profile. Terminate and wait for the child before re-raising the attachment error.

Update launch_via_cdp so failures during CDP attachment or context setup
terminate and wait for the spawned Chrome process before re-raising the original
error. Reuse the existing process-cleanup mechanism if available; otherwise add
one that handles the platform appropriately.

Accept steps in the fake mouse move.
When GFLOW_HUMAN=1, _human_click calls page.mouse.move(..., steps=...). FakeLocator.bounding_box() returns a box, so a submit test using FakePage reaches this method and raises TypeError before clicking. Add an optional steps parameter to the fake. Playwright’s mouse.move accepts that parameter. (playwright.dev)

… the patchright factory cdp_launch.py names launch_persistent_context only in its docstring and spawns system chrome.exe; both callers run ensure_profile_engine_compatible before routing to it. The CDP routing test now stubs resolve_async_playwright so it passes on CI, where patchright is not installed.

Locally both tests fail without the commit and pass with it (225 passed across the two files). Next I'll run a council review of the full PR, which covers the open CodeRabbit comments. |

Council review: 🔴 RED (reviewed at fa6547ac)
Thanks for the rework. The rebase is clean, the image-path launch fix is real, and the opt-in CDP path is a reasonable experiment. The blockers are about what the PR changes outside that opt-in.
| Dim | Verdict | Headline |
|---|---|---|
| D0 CI-mechanical | 🟢 | ruff, format, doc links and hygiene are green; test (3.11/3.12) green after fa6547ac |
| D1 Correctness | 🔴 | the default-path flag removal turns navigator.webdriver on (measured) |
| D2 Quality | 🟡 | a duplicated engine guard, env-var naming, a swallowed readiness failure |
| D3 Security | 🔴 | --remote-allow-origins=*, port TOCTOU, orphaned Chrome, a relative candidate path |
| D4 Tests | 🔴 | cdp_launch.py at 27% coverage, and no e2e or stated blocker |
| D5 Memory | 🔴 | contradicts the G12 spike, KNOWN_ISSUES, ARCHITECTURE.md:428 and memory without updating them |
| D6 UI | 🔴 | deletes _ligature, which tests/e2e/test_migrated_host_e2e.py:190 still calls |
| D14 YAGNI | 🟡 | about 110 lines are speculative, mostly GFLOW_HUMAN* |
Must-fix
- Restore
--disable-blink-features=AutomationControlledon the default launch paths.- Where:
client.py:518,ui_automation.py:~1105,transports/experimental/evaluate_fetch.py:~167, and the two test expectations. - Why: we measured it ($0,
launch_persistent_contextwith your exactignore_default_args,about:blank):This flag is the one that does the work.channel=None headless=True flag=False webdriver=True | flag=True webdriver=False channel=None headless=False flag=False webdriver=True | flag=True webdriver=False channel=chrome headless=True flag=False webdriver=True | flag=True webdriver=False channel=chrome headless=False flag=False webdriver=True | flag=True webdriver=Falseignore_default_argsalone does not. - The new comment "webdriver stays false because ignore_default_args strips --enable-automation" is false.
- The G12 spike (
docs/superpowers/spikes/2026-09-08-g12-blocks-webdriver-not-playwright.md) showed awebdriver=Truebrowser rejected at Google sign-in in 17.5 s. evaluate_fetch.pyhas no init-script override at all, so it now exposeswebdriver=Trueoutright.- If you want the flag dropped only under
GFLOW_CLI_CDP_LAUNCH=1, that's fine: gate it oncdp_launch_requested().
- Where:
- Fix the e2e break.
tests/e2e/test_migrated_host_e2e.py:190callsmigrated_composer._ligature(...), which this PR deletes. The default suite excludes-m e2e, so CI can't see it. - CDP launch hardening (
cdp_launch.py):- Drop
--remote-allow-origins=*(:183).connect_over_cdpsends no Origin header, and the wildcard lets any page the browser visits open the DevTools socket on a signed-in Google profile. - Kill the spawned Chrome if anything after
_spawnraises (connect_over_cdp,new_context, cancellation). Today it is orphaned holding the profile with an open debug port. - Replace
_free_port+/json/versionwith--remote-debugging-port=0and read<user_data_dir>/DevToolsActivePort. That avoids the bind race, where another process on the freed port can serve its ownwebSocketDebuggerUrl. At minimum, assert the WS URL isws://127.0.0.1:{port}/. - Add the
LOCALAPPDATAcandidate only when the variable is set (:55). OtherwisePath("")/…/chrome.exeresolves relative to CWD. - In CDP mode, require
channel == "chrome". The #477 guard compares the profile against bundled Chromium when there is no chrome marker, but the CDP path spawns system Chrome, or/usr/bin/chromiumon Linux despite the docstring's "never Chromium".
- Drop
- The docstring promises what the code does not do (
launch_via_cdp).viewport,locale,extra_http_headersandrecord_har_pathare dropped silently, which loses the #854en-USpin andGFLOW_CLI_HAR_PATH. Apply them, or refuse them loudly. - Diagnostics regression. The new
_open_panepoll raisesUiSelectorDriftErrorwithout_ui_failure_detail(page, phase="discover_settings_pane", ...), so exit-23 reports lose their URL, selector and screenshot. - Tests.
cdp_launch.pyneeds its own unit tests: a fakePopen, a stubbedurlopenand a fakepwcover_cdp_chrome_binary,_wait_ws_urltimeout and early exit,close()on both OSes, bothConfigurationErrors, and the new kill-on-failure.client.py's CDP branch has no test.- Estimated new-code coverage is about 40–50%, against SonarCloud's 80% floor.
- An e2e for the CDP path, or a stated blocker, is required by
AGENTS.md.
- Default-path behavior not in the CHANGELOG, and unverified. Every image submit now waits up to 15 s for
grecaptcha.enterpriseplus a fixed 1 s sleep (migrated_composer.py:~2937). The XPath selectors, the 8 s_open_panepoll and the 6 s_selectpoll also apply to the default engine. Either scope them to the CDP path, or list them in the CHANGELOG and live-verify them on the default path.
Should-fix
-
GFLOW_HUMAN/GFLOW_HUMAN_TYPE(about 70 lines):- They are off by default and have no tests or docs.
- They don't use the
GFLOW_CLI_prefix or go throughconfig.py. _human_click's blanket retry can double-click a submit that spends credits.- The PR attributes the refusal both to the grecaptcha wait and to instant paste.
Please move them to a separate PR with evidence, or drop them.
-
The
filter(has=)claim. "Resolves to zero under patchright/CDP because isolated worlds can't see the DOM" is stated in the CHANGELOG with no reproduction, and isolated worlds do share the DOM._picker_panestill usesfilter(has=). A $0 spike comparingcount()for both forms on one live page would settle it. Until then, word it as an observation. -
Move the patchright-engine guard into
cdp_launch. It is currently copied word for word inclient.pyandui_automation.py. -
Test the
_flkey acceptance. Add a unit test asserting it. -
Small cleanups: replace
_now = __import__("time").monotonicwith a plainimport time, remove the redundantpagesproperty, and remove the--enable-automationfilter, which can never match.
Confirmed good
- The CDP path is gated on patchright plus
GFLOW_CLI_CDP_LAUNCH=1. - The profile lease is taken before spawn on both sites.
Popengets a list argument, with no shell.- The XPath stays locale-invariant, anchored on the
mat-iconligature plus@role. - #909's refusal read is intact.
- No secrets appear in the diff.
Suggested path: revert the default-path flag removal, fix the e2e import and the CDP hardening items, and scope the default-path waits. Human mode can go to a follow-up. We'll then live-verify the opt-in path on a migrated profile.

Heads-up: #919 is now merged into |
|
Thanks @stgmt for the work here. I'm closing this PR, and #906 stays open as the tracking issue. Why:
The card itself is well evidenced: KNOWN_ISSUES § |
Why
On a migrated
flow.google.comaccount, Flow refuses every Playwright/patchrightsubmit with
PUBLIC_ERROR_UNUSUAL_ACTIVITYwhile the same account works fine ina manually opened Chrome window (#906). The council review correctly pointed out
that
playwright-stealth's JS evasions change almost nothing on gflow's context(#908 spike: webdriver already gone,
--enable-automationalready dropped,--disable-blink-features=AutomationControlledalready passed) — and the oneconfound it could not rule out was the launcher: a browser Chromium
recognizes as real Chrome, with a real window, focus, visibility and GPU,
rather than a patched Chromium launched headlessly with
--enable-automationremoved by flag.
This revision of the PR takes that confound head-on: instead of spoofing
stealth JS into patchright's bundled browser, it launches the installed
chrome.exeand attaches patchright to it over the CDP debug port.What
src/gflow_cli/api/cdp_launch.py(new) —launch_via_cdp(pw, kwargs):resolves the system Chrome binary (prefers real
chrome.exeunder ProgramFiles over the
.cmdshim), picks a free port, spawnschrome.exe --user-data-dir=… --remote-debugging-port=… --remote-allow-origins=*, waitsfor
/json/versionto expose a WebSocket URL, then attaches withpw.chromium.connect_over_cdp(ws_url)and reuses the first existing context(or creates one). Playwright-only kwargs (
viewport,locale,extra_http_headers) are applied to that context where CDP allows; extra--argsare forwarded except--enable-automationand friends.close()CDP-disconnects and then
taskkill /F /Ts the spawned chrome.exe on Windows(or
terminate/killelsewhere) so the debug-port chrome is never leftrunning with the user's profile.
api/client.py—_launch_persistent_contextroutes throughcdp_launch.launch_via_cdpwhenGFLOW_CLI_CDP_LAUNCH=1. The flag isopt-in and gated: it requires
GFLOW_CLI_BROWSER_ENGINE=patchrightandraises
ConfigurationErroron any other engine instead of silentlylaunching the wrong binary. The stock launcher's
--disable-blink-features=AutomationControlledarg is removed — it isitself a fingerprint (real Chrome does not carry it).
transports/ui_automation.py+transports/experimental/evaluate_fetch.py—same flag removal, plus
ignore_default_args=["--enable-automation", "--no-sandbox"]so the automation tell is gone even if Playwright wouldre-add it.
transports/migrated_composer.pyfilter(has=mat-icon-ligature)→_with_ligature()XPath descendantselectors.
has=compiles to a page-sideevaluatethat silentlyresolves to zero elements under the patchright/CDP engine, so the
model picker and submit button were unreachable even before the WAF
fired.
_open_panegains a scoped-radios retry loop (8 s) that re-resolvesthe pane locator instead of trusting a held reference across an
Angular remount;
_blocking_overlaysuses the same XPath shape.GFLOW_HUMAN/GFLOW_HUMAN_TYPE=1humanized prompt entry — per-keypresswith randomized delays instead ofinsert_text. The councilreview noted typing speed is probably not the tell; the env stays
off by default and is documented as experimental.
grecaptcha.enterprisereadiness wait, a short settle,and a
_human_click(mouse move → down → up) instead oflocator.click.Image submit: the same wait + settle + humanized click.
