The settings reference is generated, and a contract already fails when the
committed copy is stale -- so it was current. It was also wrong: the Gaming page
was documented as "Found on **gaming**" while every other group named a real
page, because a routed page with no entry in PAGE_TITLES fell back to printing
its own id.
The staleness contract could not see it. Regenerating reproduced the same wrong
file, so the copy was current and wrong at the same time -- a check that compares
output against itself cannot catch a generator that is confidently mistaken.
So the fallback is gone. A routed page with no title now refuses to render and
says which page needs one, which is what makes the next page added here
impossible to miss.

Every other form of documentation here has drifted at least once today:
search routing that pointed at a page not containing the setting, a
contract that pinned the bug the same commit fixed, and a comment in
shell.qml that failed to stop me making the exact mistake it described.
Prose describing 127 settings would drift the day after it was written.
So docs/settings.md is generated, and a contract fails the moment the
committed copy stops matching the schema. The document cannot be wrong
for longer than it takes to run the suite.
It reads the schema by parsing rather than importing, since there is no
QML interpreter here and requiring a compositor to build documentation
would be worse. That parser is the risk, so it FAILS LOUDLY: if it stops
recognising the file it exits non-zero with the reason and writes
nothing, because a partial reference is worse than a stale one -- stale
is caught by --check, partial reads as complete. Verified: with the
entry pattern broken it reports "only 0 entries parsed" and leaves the
committed file untouched.
The contract also proves --check actually compares content, by appending
a line and confirming it fails, rather than trusting a command that
returns success to mean anything.
