PR #562 added a `media:spoof_codecs` read on the C++ side --
MaskConfig::GetBool("media:spoof_codecs") in MP4Decoder and
MatroskaDecoder -- but never declared the key in settings/. Since
validate_config() drops any key it does not recognise, the documented
usage was inert:
AsyncCamoufox(config={"media:spoof_codecs": True})
-> "Skipping unknown patch media:spoof_codecs : True"
The key never reached the browser, so the feature could not be turned on
through the supported path at all. Declared in both properties.json and
camoucfg.jvv (bool, beside mediaDevices:enabled).
The new test is the general form rather than a check for this one key:
it scans patches/ and additions/ for MaskConfig::Get*/Has*("key") reads
and fails when a key is not declared in settings/properties.json. A
patch and its schema entry are two halves of one change, and shipping
only one half is a mistake this project has now made in both directions
-- canvas:seed (#721) and navigator.maxTouchPoints (#696) were declared
but unconsumed; this one was consumed but undeclared. Across the tree
the scan finds 63 reads against 109 declared keys, and media:spoof_codecs
was the only gap.
Note the runtime reads properties.json from the *installed browser
bundle*, not the repo, so this fix only takes effect for a build
packaged after it.
