Included review availability: Your plan provides up to 2 included reviews per hour; 1 remains after this review. 📝 WalkthroughWalkthroughThe pull request adds validated update manifests, optimized ranged downloads, filesystem transactions, startup recovery, Electron RPC procedures, a manifest server, and frontend download integration. Game launches wait for update recovery, and managed updates use transactional setup and completion. ChangesManaged update system
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to Managed updates now process externally sourced archives and apply staged installation changes. Unsafe directory entries can bypass path validation, potentially allowing archive contents to escape the staging directory, while transaction input and recovery gaps can leave installed files or ownership metadata inconsistent. These security and installation-integrity risks should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Greptile SummaryThe PR adds managed direct-download updates with archive validation, file reuse, transactional setup, rollback recovery, and renderer coordination.
Confidence Score: 5/5The PR appears safe to merge because no blocking failure remains in the previously reported recovery, archive-validation, or filesystem-convention issues. The current code preserves unreadable transaction state through quarantine, re-reports persistent quarantines, validates ZIP structure before extraction, bounds central-directory allocation, and rejects local-header filename mismatches.

102-120: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winConsider bounded concurrency for range downloads.
The loop fetches each range group sequentially. The planner permits up to 64 groups, and each request uses a 7.5 s timeout. On a high-latency connection the serialized round trips dominate the update time, which weakens the benefit of the ranged path.

isSafeRelativePathblocks traversal, absolute paths, and drive prefixes. On Windows, two further forms remain accepted: a colon in a later position (for exampledata:stream) creates an NTFS alternate data stream, and reserved device names (CON,NUL,AUX,COM1) resolve to devices. ZIP entry names come from remote archives, so these values are attacker-controlled.Adding a colon check and a reserved-name check keeps extraction predictable on Windows.

Inline comments:
In `@application/src/electron/handlers/handler.library.ts`:
- Around line 82-83: Update the launch recovery flow around afterUpdateRecovery
so any failed launch RPC resets the launch state from launching, allowing
PlayPage.svelte to leave the WAITING state. Ensure the reset occurs before the
recovery defect is propagated through ipcBoundary, while preserving normal
successful launch behavior.
In `@application/src/electron/handlers/handler.update-system.ts`:
- Around line 38-45: Validate transactionId against the canonical randomUUID
format before completeManagedSetup or abortManagedSetup performs any path joins,
while preserving valid transaction handling. Also validate the journal’s path
fields before using journalPath or recursively removing the transaction
directory.
In `@application/src/electron/update-system/community.ts`:
- Around line 69-79: Replace the synchronous gzipSync call in the
Effect.tryPromise request body with asynchronous gzip compression using
node:zlib/promises or a promisified node:zlib.gzip, await the result inside the
try callback, and preserve the existing manifest payload and fetch behavior.
- Around line 33-52: Update the response-body handling around the manifest fetch
to read response.body incrementally and stop once accumulated bytes exceed
maximumManifestBytes, avoiding response.text() and unbounded buffering; preserve
the existing size validation and parsing behavior. Also replace the nested
Effect.runPromise used for UpdateManifestSchema decoding with an
Effect.flatMap-based composition so decoding remains in the surrounding Effect
and preserves interruption.
In `@application/src/electron/update-system/files.ts`:
- Around line 52-71: Reuse one hashing worker across each complete scan instead
of invoking hashFiles once per batch. In
application/src/electron/update-system/files.ts:52-71, pass the full path list
or retain a worker for the scan; in
application/src/electron/update-system/zip.ts:204-214, replace the duplicate
batch loop with the shared approach. Update hashFiles in
application/src/electron/update-system/hash.ts:27-50 to expose reusable worker
lifetime or perform bounded concurrency internally while preserving existing
hash results.
Apply the same fix in `@application/src/electron/update-system/zip.ts` around
lines 204 - 214.
In `@application/src/electron/update-system/manager.ts`:
- Around line 131-150: Update the extraction flow around buildZipManifest so
manifest generation is best-effort: preserve the successfully extracted staging
directory when manifest creation fails and return a result with an absent
manifest instead of failing the operation. Remove the manifest-build error
cleanup that deletes extracted content, adjust the result type and
submitCommunityManifest call as needed, and update callers such as
beginManagedSetup to explicitly handle the missing manifest.
In `@application/src/electron/update-system/model.ts`:
- Around line 98-109: Update the key comparator in canonicalJson to sort object
keys by deterministic JavaScript code-unit ordering instead of localeCompare,
while preserving the existing filtering, recursive canonicalization, and output
format.
In `@application/src/electron/update-system/ownership.ts`:
- Around line 10-28: Optimize captureOwnershipFiles by building an
installedByPath Map alongside the existing hash index in
application/src/electron/update-system/ownership.ts lines 10-28, and use it for
unchangedPreexisting instead of scanning installed. In lines 30-59, replace the
sameOutput and samePath installed.find lookups with installedByPath accesses; in
lines 60-85, replace the installed.find lookup at line 64 similarly. Preserve
the existing installedByHash behavior while avoiding repeated linear scans at
all three sites.
In `@application/src/electron/update-system/remote.ts`:
- Around line 323-343: Update the range-download attempt in the
Effect.tryPromise block to avoid applying the 7.5-second total sourceTimeoutMs
deadline to the response body; use an idle timeout that resets whenever a chunk
arrives and is cleared when the pipeline settles, while retaining
sourceTimeoutMs for HEAD and structural probe requests.
- Around line 237-252: In the central-directory loop, update the bounds
validation before any field reads so offset + 46 must be within central.length;
return false immediately when the fixed header is truncated. Keep the existing
end, disk, and flags validation after parsing the header fields.
- Around line 359-420: Update extractEntry so compressed is created only after
local-header validation and dataOffset checks complete; ensure the stream is
destroyed in a finally block covering the pipeline, and remove the partial
destination file when pipeline processing fails, while preserving existing
hash/size cleanup and return behavior.
In `@application/src/electron/update-system/staging.ts`:
- Around line 109-124: Update findMarker to catch JSON parsing and marker file
read errors for each candidate entry, skip unreadable or corrupt markers, and
continue scanning the remaining .json files; preserve returning the first valid
marker matching path and registryPath, otherwise return undefined.
In `@application/src/electron/update-system/transaction.ts`:
- Around line 386-400: Add a TransactionJournalSchema and decode parsed journal
data within readJournal, ensuring malformed or incomplete journal.json files
return typed errors instead of reaching rollbackTransaction as invalid data.
Update recoverTransactions to handle failures independently for each
recoverTransaction call so one corrupt transaction does not abort recovery of
other directories or gate later operations.
- Around line 118-148: Update the rollback-space calculation near filesToProtect
and requiredBackupBytes so it estimates the sizes of the same existing files
that the backup loop actually copies, including unmanaged files and the
ownership-undefined case. Alternatively, if retaining the ownership-aware
estimate, filter filesToProtect to exactly that same set; ensure the
availability check and backup operation use matching file sets.
In `@application/src/electron/update-system/zip.ts`:
- Around line 39-48: Update readExactly to repeatedly read into the remaining
portion of the buffer, advancing the file position and accumulated byte count
after each read; only throw “Unexpected end of ZIP archive” when a read returns
zero before length bytes are collected, then return the fully populated buffer.
- Around line 84-129: In the ZIP entry parsing loop, reject entries whose
compressedSize, size, or localOffset equals 0xffffffff, since ZIP64 extra-field
values are not supported. After calculating each entry’s dataStart, validate
that dataStart plus compressedSize does not exceed stat.size before adding the
entry, using the existing parsed entry fields and bounds-checking flow.
- Around line 168-200: In buildZipManifest, validate the constructed manifest
with UpdateManifestSchema before returning it, and convert any schema validation
failure into FileSystemError. Return the validated manifest so manager.ts
submits only schema-compliant data to submitCommunityManifest; retain the
existing literal fields without adding a cast.
In `@application/src/frontend/lib/downloads/services/DirectService.ts`:
- Around line 97-121: In
application/src/frontend/lib/downloads/services/DirectService.ts:97-121, update
the optimized branch so the inserted managed-update record is guaranteed to
transition from downloading to setup-complete or error, and ensure the
ddl:download-complete listener is registered before insertion. In
application/src/frontend/components/PlayPage.svelte:114-114, report a blocked
launch to the user instead of returning silently when a non-terminal update
record is detected.
In `@application/tests/update-system.test.ts`:
- Around line 101-118: Split the test around isStructurallyValidManifest into
two independent invalid manifests: one changing only the second entry’s path to
match the first, and another changing only its range to be out of source bounds.
Decode each separately and assert that both results are Left.

- Around line 220-240: Update inspectRemoteSource to use a shared HEAD probe
timeout constant instead of the hardcoded 3,000 ms value, consolidating the
related timeout definitions across the update-system modules while preserving
the existing timeout behavior.
- Around line 88-94: Update the Effect.catchAll handler in the staging/update
flow to log a warning with the failure details before returning the existing
fallback result. Follow the warning pattern used by the remote update flow,
covering failures from registerStaging or removeStaging without changing the
fallback behavior.
- Around line 160-203: Extract a shared decodeManifest helper for
UpdateManifestSchema decoding and its existing Invalid update manifest error
mapping, then reuse it in beginManagedSetup and finishManagedSetup while
preserving their transaction-specific error mapping. Remove the unnecessary
manifest as UpdateManifest casts from prepareTransaction and commitTransaction
calls; use the decoded manifest directly.
In `@application/src/electron/update-system/model.ts`:
- Around line 111-117: Update isSafeRelativePath to reject any path segment
containing a colon and reject Windows reserved device-name segments, including
reserved names with extensions or trailing spaces/dots and the COM/LPT numbered
forms. Preserve the existing traversal, absolute-path, null-byte, backslash, and
.ogi-update-ranges checks.
In `@application/src/electron/update-system/planner.ts`:
- Around line 71-101: Consolidate the duplicated grouping logic by exporting the
existing coalescing helper from remote.ts and reusing it in
measureCoalescedRanges and the downloader, passing the configured
coalesceGapBytes value so planning and requests use identical boundaries. In
measureCoalescedRanges, reset end when starting a new group to make each range
independent while preserving the existing sorted-range behavior.
In `@application/src/electron/update-system/readiness.ts`:
- Around line 10-34: Update startUpdateRecovery and afterUpdateRecovery so
recovery failures are logged through the existing main-process logger and
callers do not remain permanently blocked by a single failed attempt; provide an
explicit retry path that resets the started and recoveryFailure state before
rerunning recovery, while preserving the successful recovery flow. Also ensure
afterUpdateRecovery handles a recovery that was never started with a bounded
failure or diagnostic instead of waiting indefinitely, and retain the existing
failure propagation for callers.
In `@application/src/electron/update-system/remote.ts`:
- Around line 102-120: Update the range-group processing around fetchRange and
extractEntry to use bounded concurrency, such as Effect.forEach with a small
concurrency limit, so multiple groups can download simultaneously without
exceeding resource limits. Preserve sequential extraction and cleanup within
each group, including its existing entry order and failure behavior.
In `@application/src/electron/update-system/staging.ts`:
- Around line 36-49: Update registerStaging so cleanup only removes the staging
directory when this invocation created it; track whether path existed before
fs.mkdir and skip recursive removal for pre-existing directories, while
preserving cleanup for newly created directories and propagating the original
failure.
In `@application/src/electron/update-system/transaction.ts`:
- Around line 490-498: Refactor cleanupPreparation to compose
removeStaging(extractedPath) directly with the filesystem cleanup effect instead
of calling Effect.runPromise inside Effect.promise. Preserve the sequential
order: remove directory first, then run removeStaging within the same Effect
runtime so interruption and tracing propagate.
In `@application/src/frontend/lib/downloads/services/DirectService.ts`:
- Around line 94-96: Update the Effect.catchAll fallback in DirectService to log
the caught failure before returning the fallback result. Preserve the existing {
kind: 'fallback' } behavior while ensuring manifest validation failures and RPC
faults include their cause in the diagnostic log.
In `@application/src/frontend/store.svelte.ts`:
- Line 15: Update the UpdateManifest import in store.svelte.ts to use the
consistent .js module specifier style established by electron-rpc.ts, while
preserving the existing imported symbol and type-only import.

Description
Adds managed direct-download game updates that reuse unchanged owned files when worthwhile, validate community manifests, and fall back to the existing full-update path when optimization is unavailable. Setup changes are applied through recoverable transactions so interrupted or failed updates can roll back safely.
Example
For an update where most archive data is unchanged, OpenGameInstaller now reuses verified installed files, downloads only required archive ranges, runs addon setup in a staged transaction, validates the resulting library metadata, and commits atomically.
