Match the json-patch camelCase key names the Hasheous endpoint expects,
and update the lookup_rom test assertions accordingly.

Annotate request_kwargs as dict[str, Any] to accept the list json payload,
and file_hashes as dict[str, str | None] so the chd_sha1_hash branch and the
md5/sha1/crc branch unify cleanly.

The Hasheous ByHash endpoint now accepts an array of hash objects rather
than a single one. Send the hashes of every top-level file (using
chd_sha1_hash exclusively for files that have one) to improve lookup
accuracy, instead of picking only the largest file.

saves responses now include one device_syncs entry per device that has
synced a save, not just the caller's, so clients can tell which devices
hold a save. is_current is computed per entry and the caller's own entry
is ordered first for backward compatibility.
add a saves.origin_device_id column (migration 0081) recording the
device that created a save, set on initial upload only, surfaced as
origin_device_id on the save schema.
ScreenScraper matching skipped the stronger jeuInfos (romnom + systemeid)
lookup for any file without a hash, falling straight through to the weaker
jeuRecherche name search. Files are un-hashed for NON_HASHABLE_PLATFORMS
(PS3/4/5, Switch, Wii U, Xbox, etc.) and whenever SKIP_HASH_CALCULATION is
set, so those platforms matched worse than they could.
The transport already supports a hash-less jeuInfos?romnom=...&systemeid=...
request, so relax lookup_rom's early-return: only bail when there is neither
a hash nor a filename to match on. jeuRecherche stays the last-resort
fallback, keeping this quota-neutral.

The scan loaders no longer eager-load `Rom.files` (#3425 + follow-ups), so
the hash-based metadata lookups can't rely on `rom.files` being populated —
`hasheous`/`ss` `lookup_rom` read `RomFile.is_top_level`, which dereferences
`RomFile.rom.full_path` and would raise `DetachedInstanceError` once the
session closed.
Add `DBRomsHandler.rom_files_for_rom_id`, which loads a ROM's files on demand
with the `RomFile.rom` backref eager-loaded (`load_only(fs_path, fs_name)`).
The scan path uses it as a fallback only when the filesystem walk yielded no
files (e.g. an unchanged rescan), behind a per-ROM `functools.cache` helper so
the playmatch/hasheous/ss lookups share a single DB fetch.

filter_roms feeds both the gallery/list endpoint (SimpleRomSchema, no
files) and the feed endpoints (which iterate rom.files / is_top_level).
The cleanup commit's unconditional selectinload(Rom.files) + joinedload
made the gallery/list and filter-value paths pay for files they never
serialize.
Gate the files load behind a new `include_files` flag (default False),
mirroring the existing `include_file_stats` opt-in, and plumb it through
get_roms_scalar. The 9 feed endpoints that actually read rom.files opt
in; the gallery/list, filter-values, identifiers, smart-collection, and
the three feeds that don't touch files (webrcade, fpkgi, kekatsu) skip
the load entirely — keeping the gallery query at zero file cost.

The SS metadata handler pre-encoded the name-search term with quote()
before handing it to the service layer, which percent-encodes the query
again via yarl's with_query(). This double-encoded any character that
needs URL-encoding (e.g. "+" -> "%2B" -> "%252B"), so the request URL
carried a doubly-escaped term.
Pass the raw (unidecode-transliterated but un-percent-encoded) term to
search_games() in both _search_rom() and get_matched_roms_by_name() and
let the URL builder encode it exactly once. The scan now sends e.g.
recherche=...%2B... instead of ...%252B...
This is a request-correctness fix. It does not, on its own, make every
previously-unmatched title match: ScreenScraper's jeuRecherche normalizes
punctuation and applies its own relevance ranking, so some titles still
return no results for the full filename-derived term (verified directly
against the API). Improving name-search robustness is a separate concern.
Add TestSearchTermEncoding regression tests covering the un-pre-encoded
term, preserved unidecode transliteration, and a single-encoded request
URL (%2B, never %252B).

Restore the "platform only" contract of `get_roms_by_fs_name` (per its
docstring) by dropping the `selectinload(Rom.files)` + `joinedload`. That
load only existed for `scan_rom`'s rare `fs_rom["files"] or rom.files`
fallback, but it forced files (and a per-file join back to roms) for every
ROM in a scan batch — expensive on large platforms, and only used when the
filesystem scan yielded no files.
Instead, fetch the persisted files on demand: `scan_rom` now resolves match
files via a small helper that returns the filesystem-scanned files, falling
back to `db_rom_handler.get_rom_files_by_rom_id(rom.id)` only when there are
none. The new getter eager-loads the `RomFile.rom` backref so `is_top_level`
keeps working on the detached results (the rare path was already latently
broken on master, which loaded files without the backref).

Replace the `_link_rom_files_to_parent` post-fetch hook with the
declarative loader pattern PR #3425 originally removed, restoring
`joinedload(RomFile.rom).load_only(Rom.fs_path, Rom.fs_name)` on the two
queries that still load `Rom.files` (`with_details` and
`get_roms_by_fs_name`).
#3425 dropped that joinedload everywhere as part of denormalizing file
stats into the `multi_file` / `top_level_file_count` column properties.
But `is_top_level` / `file_name_for_download` (multi-file downloads, 3DS
QR codes, metadata matching) still read `RomFile.rom.full_path`, so the
two file-loading paths were over-cleaned, causing a `DetachedInstanceError`
(500) on multi-file downloads once the session closed.
The gallery query (`filter_roms`) dropped `Rom.files` entirely and is
untouched, so the performance win from #3425 is preserved; the restored
join only adds an index-backed PK lookup of two columns to the existing
files `selectin` on the detail/scan paths.
https://claude.ai/code/session_01PSXKmejPRzdxLFMN6P2QQ4
PR #3425 dropped `lazy="joined"` from `RomFile.rom` and removed the
`joinedload(RomFile.rom)` from the ROM loaders to speed up the gallery
query. That left the `RomFile.rom` backref unpopulated. Single-file
downloads only read `RomFile.full_path` (built from `file_path`/
`file_name`), so they kept working, but multi-file (game folder)
downloads call `file_name_for_download()` / `is_top_level`, which read
`self.rom.full_path`. With no eager-loaded backref, that triggered a
lazy load on a detached instance once the handler session closed,
raising `DetachedInstanceError` and returning a 500.
Rather than reverting the loader changes (and the gallery gains), wire
the `RomFile.rom` backref up in Python from the parent ROM we already
hold in memory, via `set_committed_value`. This is zero extra DB cost
and only runs on the detail/download paths (`with_details` and
`get_roms_by_fs_name`); the optimized `filter_roms` gallery query is
untouched.

New Nintendo 3DS games never matched ScreenScraper because the platform
was missing from SCREENSAVER_PLATFORM_LIST. With no entry, get_platform()
returns ss_id=None and scan_handler skips the entire ScreenScraper lookup
(hash and filename) for the platform, reporting everything as unmatched.
ScreenScraper has no separate New 3DS system; New 3DS games live under the
regular Nintendo 3DS system (ID 17). Alias New Nintendo 3DS to that system,
matching the existing Famicom->NES, Super Famicom->SNES, and DSi->DS aliases.

IGDB catalogues a console and its regional twin as two separate
platforms (SNES/Super Famicom, NES/Famicom). RomM locked each IGDB
search to a single platform id, so a region-exclusive title catalogued
under only the twin — e.g. the Japan-only Super Famicom game
"Rudra no Hihou" (platform 58) scanned from an `snes` folder
(platform 19) — was filtered out before name matching ran and never
matched.
Include a platform's regional twin in the IGDB platform filter so both
are searched. A non-twin platform keeps the exact existing query
(`platforms=[19]`); a twin produces an OR group
(`(platforms=[19] | platforms=[58])`), leaving all other platforms and
recorded cassettes unchanged.

IGDB scans dropped games whose filename uses a localized (non-English)
title even when that title exists in IGDB's alternative_names. The
alternative_name wildcard search surfaced the correct game, but
_search_rom() rebuilt its name->game candidate dict using only the
primary English name, so the Jaro-Winkler re-check scored the localized
term below threshold and discarded the match (issue #3435).
Add _index_games_by_searchable_name(), which indexes each game by its
primary name plus alternative_names and game_localizations titles, and
use it for both candidate-building passes in _search_rom(). Primary
names keep precedence (lowest-igdb-id tiebreak); alternative/
localization titles fill in only names not already claimed.

The archive branch of get_rom_files (introduced in #3412) was missing
the RAHasherService.calculate_hash call that exists in the non-archive
branch, causing all archive-format ROMs to produce an empty ra_hash
during scanning regardless of platform.
The RA hash call is now made for archive ROMs, mirroring the existing
non-archive behaviour. The RA_BUFFER_HASH_UNSUPPORTED skip logic in
RAHasherService already handles disc-based platforms (PSX, PS2, PSP,
Saturn, Dreamcast, etc.) so those continue to be excluded automatically.
Also improves handling of folder-based multi-file ROMs whose directories
contain compressed files. RAHasher cannot process archives via the /*
glob and fails with "Could not open file". The fix mirrors the existing
CHD folder logic: for cartridge platforms the largest archive in the
folder is passed directly to RAHasher for buffer hashing; for disc
platforms the call is skipped as buffer hashing is unsupported.

When sending a hash lookup to ScreenScraper, romnom was always set to the
archive filename on disk (e.g. Mario.zip). For single-file archives, the hash
is computed from the internal file (e.g. mario.n64), so sending the archive
name sends slightly incorrect info to ss.fr during a KO scrape.
When archive_members has exactly one entry, romnom now uses that member's
name. Multi-file archives and non-archive files continue to use the filesystem
filename unchanged.

FSAssetsHandler.compute_content_hash and _compute_zip_hash were
building full paths via f"{self.base_path}/{file_path}". self.base_path
is already a pathlib.Path (resolved by FSHandler.__init__), so the
f-string forced it to str, hard-coded the separator, and re-parsed --
fine on Linux but a footgun if a caller ever sneaks a leading slash or
the path needs Path semantics elsewhere.
Switch both spots to self.base_path / file_path, which is what every
other FSHandler subclass in this module already does (e.g.
FSRomsHandler, FSResourcesHandler, FSSyncHandler all join Path objects
directly).
Three sync callsites (endpoints/sync.py, sync_watcher.py, and both
branches of tasks/sync_push_pull_task.py) ran get_saves(...) and then
discarded archival null-slot rows in a Python list comprehension. On
libraries with many archival/web-UI uploads that's a strict waste:
those rows are pulled from MariaDB, hydrated into Save model instances,
and then immediately filtered out.
Add a slot_not_null bool kwarg to DBSavesHandler.get_saves and apply
the filter in the SQL query. Update all four callsites to use it and
drop the Python-side comprehension. Default stays False so unrelated
callers keep the current behavior.
get_all_saves() materialized every Save row across all users into a
single .all() list. On instances with very large libraries that's a
real RAM ceiling and pins every row for the lifetime of the recompute
run.
Replace it with get_saves_after_id(after_id, limit) and have the
recompute task drive keyset pagination in PAGE_SIZE-row chunks. SQLAlchemy
streaming via .execution_options(yield_per=...) is incompatible with the
per-call session lifetime that @begin_session enforces (the session
exits before the consumer iterates), so keyset paging from the caller is
the cleanest fit.
Behavior is unchanged: same row coverage, same idempotency, same
counters. Memory usage drops from O(all saves) to O(PAGE_SIZE).
Cleanup pass on save-sync addressing three independent failure modes
that interact in production data: content_hash drift between client
and server, null-slot archival saves leaking into sync flows, and
content-hash dedupe collapsing legitimately-distinct slots.
Bug fixes
- compute_content_hash dispatched on zipfile.is_zipfile(relative_path),
which silently returned False whenever the process's CWD wasn't
ASSETS_BASE_PATH. Every zip save fell through to the raw-MD5 branch,
persisting hashes that disagreed with clients computing the intended
per-entry zip-hash. Resolve to a full path before the dispatch.
- _build_negotiate_plan, sync_push_pull_task, and sync_watcher all
treated null-slot saves as sync-eligible. Null-slot saves represent
web-UI / archival uploads; including them in negotiate plans matched
them against device pushes by filename and overwrote archival data.
Filter null-slot saves at all three call sites.
- get_save_by_content_hash matched on (rom_id, user_id, content_hash)
only, so identical bytes uploaded to different slots collapsed into
one record. Scope the lookup by slot when provided so clone-save-
to-new-slot creates a distinct row per slot.
- get_save_by_filename matched on (rom_id, user_id, file_name) only.
When two uploads to different slots happened in the same wall-clock
second (the datetime tag is per-second), the second upload UPDATED
the first record's slot instead of creating a distinct row. Scope
the filename lookup by slot too.
One-shot recovery
- New recompute_save_content_hashes manual task walks every Save row,
recomputes via the fixed dispatch, and updates rows whose values
differ. Idempotent; safe to re-run.
- Backend startup runs a COUNT(content_hash IS NULL) query and, if
any rows exist, enqueues the recompute task on the low-priority
RQ queue. The API process moves on; the worker handles the
recompute out-of-band. Subsequent restarts find zero NULL hashes
and skip. Admins can also trigger the task manually.
Test infrastructure
- Added tests/_zipfile_shim.reload_zipfile() mirroring the pattern
from utils/zip_cache.py for the same zipfile-inflate64 + CPython
3.13.5 incompatibility. Test fixtures that build ZIPs call it
immediately before opening the archive.
Internal members of multi-file archives (zip/tar/7z/rar) are now hashed
individually (crc/md5/sha1) and stored in a new `archive_members` JSON
column on the archive's RomFile, alongside the existing composite hash
used for hash-database matching. Only the archive itself is surfaced as
a RomFile so full_path keeps pointing at a file that exists on disk,
which is the constraint that previously forced us to choose between
composite-only or broken downloads.
