Use a payload-neutral inherited example.
This @example appears on generated QueryObserver, FocusManager, and OnlineManager reference pages. QueryObserver and MutationObserver listeners receive result objects. FocusManager and OnlineManager listeners receive booleans. These payloads are not QueryCache events, so event.type and event.query are invalid guidance outside QueryCache.
Replace the shared example with a callback that does not inspect payload fields, or keep this example only on QueryCache, then regenerate the references.

🎯 Changes
Class pages render their methods as headings rather than table rows, so they were outside the sweeps that filled in the property tables. Two base classes had no JSDoc at all, and because everything inherits from them, that single gap repeated across the reference:
Subscribable—subscribeandhasListeners, inherited byQueryCache,MutationCache,QueryObserver,QueriesObserver,MutationObserver,FocusManagerandOnlineManager.Removable—destroy, whichMutationinherits as is (Queryoverrides it and documents its own).Both classes also gained a summary, since neither had one.
That's 119 method entries with no description across the seven adapters, from two source files.
Wording checked against the implementation
subscribereturns a closure callinglisteners.delete(listener), so it's documented as returning an unsubscribe function. The@returnssays the base class never drops a listener by itself, but notes that some subclasses do —QueryObserver.destroy()andQueriesObserver.destroy()both resetlistenersto an emptySet, so a flat "nothing is cleaned up automatically" would have been wrong.destroyis described as something a subclass may override: onlyQuerydoes, addingthis.cancel({ silent: true }).Mutationuses the inherited one, which is why its page was blank.FocusManager/OnlineManagerrather thanfocusManager/onlineManager— the classes extendSubscribable; those exports are instances of them.@examplemirrors the one already onQueryCache, andevent.type/event.queryare real fields onQueryCacheNotifyEvent.Effect
Methods rendering with no description: 335 → 216.
Of the 216 left, 210 are
protectedmembers that shouldn't be published at all — #11564 removes those viaexcludeProtected. The remaining 6 areprepareStackTrace, inherited from Node'sErrorbyCancelledError.Generated docs
70 files change; 63 are content (a page usually gains both
subscribeandhasListeners), and 7 areDefined in:line-number shifts.✅ Checklist
