The old gate ran firefox --headless --screenshot, which renders fine even when the juggler automation layer is missing from the package — so a binary Playwright can't actually drive (firefox-8) passed and shipped broken. Replace it with a real drive gate: a 5-leg matrix that launches each binary over the juggler pipe on its native runner, loads a page, and round-trips JS (also asserts navigator.webdriver stays hidden). Headless and no screenshot, so it stays GPU-free on the hosted runners and needs no proxy or secrets. Same logic is reusable standalone via verify-assets.yml to drive-test an existing release's assets without a rebuild.

"""CI drive gate — the firefox-8 catcher.
|
|
|
|
A raw `firefox --screenshot` proves nothing about automation: a juggler-less
|
|
binary renders a screenshot just fine and ships broken (firefox-8 did exactly
|
|
that). This DRIVES the binary the way users will — Playwright launches it over
|
|
the juggler pipe, loads a real page, and round-trips JS. A binary with a
|
|
missing/broken juggler throws TargetClosedError here and the gate fails.
|
|
|
|
Headless, NO screenshot → GPU-free, so it can't false-fail on GPU-less hosted
|
|
runners. Zero proxy / zero secrets → safe in public CI. (The proxy realness
|
|
gate — fppro/webrtc — stays local, it needs secrets.)
|
|
|
|
Usage: python ci_drive_gate.py /path/to/firefox[.exe | .app/Contents/MacOS/firefox]
|
|
Exit 0 + "DRIVE GATE OK ..." on success; non-zero with a reason on failure.
