Add a gamedata cleanup to the Nitro Cleanup panel: a read-only preview
plus an apply run that dedupes FurnitureData classnames and removes
rows and figure entries that reference nothing.
Three passes run in a fixed order, because cleanFigureMap has to precede
cleanFigureData: dropping the part that points at a set is what makes
that set unreferenced.
A pass refuses to write when it would delete more than maxRemovals rows
(default 500) and reports the reason, a wrong asset directory otherwise
turns every row into an orphan and one call would empty the file. Passes
that would act on empty input (no libraries, no sets) treat that as a
missing file rather than as a reason to delete everything. Every write
copies the file to a timestamped backup first, so a pass that turns out
to be wrong can be undone by hand.
The plan reads FurnitureData once and hands the parsed copy to both
furniture passes; the file is tens of megabytes in a real deployment.
The cleanup scan used to read every .nitro bundle in full and decompress
the large PNG texture just to confirm the file is structurally valid. On
directories with hundreds of thousands of bundles this took minutes, the
reverse proxy cut the request at its 30s timeoutable with an HTML 504, and
the panel then crashed with "Unexpected token '<'".
Validate bundles with a cheap header-only read (a few KB, no decompression)
that mirrors parseNitroBundle's byte layout; only files whose header looks
suspicious get the expensive full parse. Robust against downloads that
landed as an HTML error page, truncated or zero-filled files. The scan
drops from minutes to seconds on large nitro directories.
Also guard the panel against non-JSON (proxy error page / HTML) responses
so it reports a clear error message instead of a JSON parse failure.
Scan distinguishes fake, broken, and orphaned SWF/icon assets with age
metadata, deletes per asset kind, re-downloads broken nitro bundles from
configured sources, auto-cleans old fake leftovers, and exports a JSON
manifest. Adds rebuild and auto-clean API endpoints with audit coverage
and a housekeeping preview route under the hotel domain.
Verified: full vitest suite (2213 tests), typecheck, and biome all pass.
