Include media.search cursors in the invalidation contract.
media.search is cursor-paginated, and hidden preference changes alter its result set. This text tells clients to discard only browse and letter-index cursors. A client can reuse a stale search cursor and receive an inconsistent page or a cursor error.
State that clients must also discard media.search cursors, or document why search cursors are excluded.

Keep the UserDB preference and MediaDB projection consistent on failure.
SetMediaUserHidden commits the UserDB preference before MediaDB.UpdateMediaTags runs. If the projection update fails, the handler returns an error while UserDB contains the new value and MediaDB retains the old projection. The reapply path runs only during indexing, not during the failed request. Use a durable reconciliation mechanism or a concurrency-safe conditional rollback.

Validate visibility at the shared search-cursor boundary.
HandleMediaSearch uses its own cursorData codec, separate from the browse cursor validation. Store the effective ExcludeHidden mode and media-preferences revision in every search cursor, including legacy and sorted cursors. Reject the cursor before SearchMediaWithFilters when either value changes; this prevents skipped or repeated results after a mode or preference change.

Preserve the empty-system route-count contract.
When opts.Systems is empty and hidden media exists, this branch calls sqlVisibleRouteCounts without a system predicate. It returns route counts from all systems. The existing unfiltered branch returns an empty map for the same input. Check len(opts.Systems) == 0 before this branch.

Hiding a single entry sent every browse aggregate down its media-scan fallback: root counts, directory listings, directory counts, route counts and system root candidates all abandoned the browse cache and recomputed from Media through a NOT IN subquery. On the 229,727-media MiSTer test device that took media.browse from ~0.1s to a 30s deadline failure, and system-scoped browse to 9-18s. The behaviour was binary on "any hidden row exists", not proportional to how many. Keep every cached path and subtract the hidden set from its result instead. Hidden rows are read once per query into a small in-memory set and applied as arithmetic: directory and route counts lose their hidden contribution, directories and routes left empty are dropped, and a paged directory listing over-fetches by the number of directories hiding could empty so the page still fills. Root candidates probe for a remaining visible row only in subtrees that hold hidden media, and per-system counts subtract from the shared generation cache rather than re-aggregating behind a NOT filter. The media-scan fallbacks keep their SQL filter for when the cache is cold. Also fixes a pre-existing bug the PR's routing hid: sqlBrowseVirtualSchemes looked the browse root up as "" while BrowseDirs stores it as "/", so a populated cache dropped every virtual scheme root from the pathless listing. On the test device scummvm:// is now listed again. Measured on device, browse median at 0/1/10/100/1000 hidden: roots 0.11/0.12/0.12/0.17/0.56s, system contents 0.29/0.33/0.34/0.46/1.49s.
…edges A media.search cursor carried no visibility state, so switching includeHidden mid-list or hiding an entry between pages silently skipped or repeated rows. Search cursors now carry the same mode and preference revision browse cursors do and are rejected when either moves; media.history keeps an unstamped cursor because its result set does not move when a preference changes. Bound the child-directory IN list built when counting directories that hidden media emptied, since how many directories hold hidden media is user-driven. Random weighting now asks SystemMediaCounts for visibility explicitly instead of relying on the NOT filter already injected into its tag list, which kept it on the cached per-system totals. The excludeHidden variadic on BrowseRootCounts and SystemMediaCounts became a plain parameter so that choice is visible at every call site, and the hidden-tag check uses the tags package constants. Tests cover the scope boundaries the subtraction has to respect: a nested hide emptying a whole branch, a sibling sharing a name prefix, a loose file directly in the browsed directory, another system's media in the same directory, and a hidden row that has since gone missing. Each was confirmed to fail against a deliberately broken match.
RandomGameWithQuery excluded hidden media unconditionally, so a ZapScript random asking for user:hidden built a query that could never match. Apply the same exception browse and search do: a required user:hidden or user:favorite filter is an explicit ask for those entries. The rule now lives beside the other visibility policy in visibility.go so all three callers read the same one.
Adds the two visibility outcomes the earlier tests left uncovered: a drop candidate that survives, so the over-fetched directory page has to be trimmed back to the requested size and the next page still starts after it, and a route whose media is entirely hidden dropping out of the browse roots.
