Reviewer's GuideExtracts the desktop storage/filesystem recovery core: filesystem load errors now retain project identity, corrupt project folders are moved—not deleted—to collision-safe quarantine locations with typed failures and logging, and the capability is exposed through an optional storage-backend contract with IndexedDB no-op behavior. Direct regression tests cover preservation, concurrency, failure paths, backend delegation, and backup compatibility; README metrics are updated accordingly.

This PR successfully implements preserve-first desktop storage recovery with collision-safe quarantine paths. The implementation correctly handles corrupt projects by moving them to a quarantine directory while preserving all content, includes proper error handling with typed failures, and safely handles concurrent recovery scenarios. The comprehensive test coverage validates all core behaviors including edge cases. No blocking issues found.

There was a problem hiding this comment.
When the rename fails and the source disappears because of a concurrent deletion or another failure rather than a successful quarantine, this branch reports already-preserved solely from !sourceExists; the added test even simulates this by removing the source without creating a copy. A recovery caller can therefore proceed under a false preservation guarantee while no recoverable project exists. Only return already-preserved after locating a corresponding quarantine destination; otherwise classify the ambiguous outcome as an I/O failure.

When a project ID consists only of characters removed by sanitizePathSegment, such as an imported ID of "///", saveProject, loadProject, and deleteProject use the sanitizer's default item fallback, but this method targets project. Thus a project saved under projects/item cannot be quarantined using the same raw ID: this probe checks projects/project, returns not-found, and leaves the corrupt project in the active namespace. Use the same fallback as the other project-path methods.

There was a problem hiding this comment.
When an imported project has an ID of . (the import schema permits any string), this sanitizer returns . unchanged, so Tauri resolves projects/. to the entire projects directory. If that project later fails to load and recovery calls quarantineProject('.'), the rename moves the whole projects directory into quarantine rather than only the affected project, making every desktop project disappear from the active namespace. Reject . and .. after sanitization before using the segment in filesystem operations.

When a project ID contains only stripped characters such as ***, this save path now falls back to projects/project, while loadProject, deleteProject, and quarantineProject treat the same raw ID as invalid and return null, no-op, or not-found. Consequently, a successfully saved project cannot be addressed through the backend again using its original ID. Fresh evidence in the current diff is the new ?? 'project' save fallback alongside the shared helper's null result; either reject the save or normalize every operation to the same fallback.

There was a problem hiding this comment.
When upgrading a desktop profile that previously saved an imported project with an unusable ID such as ***, the parent implementation persisted it under the sanitizer fallback directory projects/item while retaining id: "***" in project.json. Cold boot still lists and loads item, but the hydrated raw ID reaches this new unconditional rejection on every subsequent autosave, so the project becomes permanently unsavable and the pre-close flush prevents a normal quit. Fresh evidence in the final tree is this rejection without any normalization or migration for data already written by the prior behavior; normalize the loaded ID to its directory identity or preserve a compatible legacy path before rejecting new saves.

There was a problem hiding this comment.
When a legacy project has an unusable ID such as ***, its main file was stored under the sanitizer's default projects/item, while binder assets and codex/RAG data were stored under projects/project because those stores use a different fallback (assetFsStore.ts:73 and codexFsStore.ts:24-25). Rewriting the loaded ID to item makes subsequent auxiliary reads target projects/item, so existing binder attachments, codex data, and RAG vectors appear to disappear. Migrate those directories or preserve a compatible auxiliary-storage identity when normalizing the project.

There was a problem hiding this comment.
For a legacy project stored as projects/item with auxiliary data under projects/project, this registers the compatibility route only in an in-memory map and then changes the returned project ID to item. Once that project is autosaved and the app restarts—or it is simply loaded again—the persisted ID is now valid, so migrateLegacyProjectIdentity clears/omits the route and Binder, Codex, and RAG reads target projects/item, making the still-unmoved legacy data disappear. Fresh evidence in the current diff is that lines 208–210 add a transient policy while normalizing the durable identity without moving or durably recording the auxiliary-storage identity.

When a desktop user restores a snapshot created before this change from a project whose ID was unusable (for example ***), the snapshot still contains that raw ID: the old saveProject snapshotted flat before writing it, while getSnapshotData and restoreSnapshotThunk return/install the payload without running the new identity migration. The restore therefore appears successful, but the ensuing debounced autosave and every close-time flush hit this new throw, so edits to the restored state cannot be persisted. Fresh evidence beyond the repaired main-project load path is that snapshot restoration still bypasses migrateLegacyProjectIdentity; normalize such snapshot data before it reaches this rejection.

When a normalized legacy project is already loaded and a later reload encounters a transient read failure—for example, while libraryBackupService re-reads the current project—this clears its in-memory auxiliary policy before the read succeeds. The thrown ProjectLoadError is caught by the backup path, but subsequent Binder, Codex, and RAG calls now target the normalized directory instead of the verified legacy directory, making existing data disappear for the rest of the session and potentially splitting later writes across both locations. Clear or replace the policy only after a successful load, while retaining it on I/O or parse failures.

When the legacy Codex file exists but its read fails transiently, such as from a lock or temporary I/O error, this catch treats the failure like negative ownership evidence. migrateLegacyProjectIdentity then normalizes the project to its directory ID without registering or persisting the auxiliary route; the next autosave makes that decision durable, and the existing Codex and RAG files under projects/project become inaccessible. Distinguish an unreadable evidence file from a verified mismatch and defer migration or preserve the route until inspection can complete.

When deleting a migrated legacy project and any auxiliary removal fails, deleteBinderAsset, deleteStoryCodex, and deleteRagVectors all catch their own filesystem errors, so execution still reaches this unconditional policy clear and deleteProject reports success. Because the primary project directory has already been removed, the remaining Binder, Codex, or RAG files are now orphaned and the routing needed to retry their deletion is lost. Make legacy cleanup failures observable and retain enough identity information to retry before declaring deletion complete.

When loading a legacy project whose persisted id is absent or empty, the old runtime stored its main file under the title-derived directory but routed Binder assets through projectStorageId to projects/browser-project and Codex data through the listener fallback to projects/default. This migration changes the returned ID to the title-derived directory without registering either of those fallback routes, so the existing Binder and Codex data immediately appears missing and the normalized autosave makes that split durable. Inspect and preserve the actual per-kind fallback paths before normalizing ID-less projects.

When a legacy snapshot or project with an unusable ID is saved while its Codex or Binder evidence has a transient I/O failure, inspectLegacyAuxiliaryEvidence returns inspectionComplete: false, but this expression converts that result to null metadata and allows the save to normalize the persisted ID. After restart, the verified auxiliary route is no longer recoverable and the existing data appears missing. Fresh evidence beyond the repaired load path is that resolveLegacySaveIdentity still returns success without checking inspectionComplete; defer or reject this save instead.

When a normalized legacy project with persisted routing metadata is reloaded and probing projects/project/project.json fails transiently, this catch returns true, so the caller treats the fallback as a confirmed legitimate-project collision, clears the verified policy, and still completes the project load. Binder and Codex data then disappear for the session—and on a cold start no policy exists to retain. Fresh evidence after the earlier reload fix is this new error-to-collision conversion; propagate an I/O result rather than treating an unreadable path as affirmative evidence.

When a legacy Binder asset ID is . or .., sanitizePathSegment(assetId, 'asset') leaves it unchanged, so the existing store can legitimately address files such as .bin and .meta.json and the migration records that ID as evidence. This metadata validator instead applies the project-path rule and rejects the persisted routing record on the next restart, after which the asset under projects/project/binder appears missing. Validate Binder IDs with the same asset-path normalization used by binderAssetPaths rather than rejecting project pseudo-segments here.

When a migrated invalid-ID project has registered a route such as item -> project, and a valid project whose ID is project is imported or saved later in the same session, this branch accepts the new identity without invalidating policies that target it. Until restart, Codex and matching Binder reads, writes, or deletion for item are therefore routed into the newly legitimate project's directory, potentially exposing or overwriting its auxiliary data; the collision check only repairs this on a subsequent load. Clear every legacy policy targeting safeProjectId before making that project path active.

When a normalized legacy project is deleted after a restart without first being loaded—for example, by deleting a non-active project from a library—the in-memory auxiliary policy is empty even though project.json contains persisted routing metadata. This removal deletes that sole metadata record before the later cleanup queries run, so those queries return no legacy Binder or Codex identities, deletion reports success, and the fallback files are permanently orphaned. Read and validate the persisted routing metadata before removing the main directory rather than requiring a preceding loadProject call.

When a migrated legacy project such as item has verified Binder or Codex data routed to projects/project, this rename moves only projects/item and then reports a successful quarantine. The returned quarantine path therefore omits part of the project, while after restart the routing metadata is no longer loadable from the active namespace and those auxiliary files are orphaned from the quarantined project. Move the verified routed assets with the project or retain durable routing metadata alongside the quarantine.

When a legacy invalid-ID project has been loaded but its normalized main file has not yet been autosaved, a Codex autosave routes to projects/project while writing the normalized projectId such as item. If the app exits or the main save fails before persisting the routing metadata, the next load compares that Codex only with the old raw ID such as ***, rejects valid ownership evidence, and makes the Codex inaccessible. Revalidation should accept the verified normalized directory identity as well as the legacy raw ID.

For a migrated project that has both current Binder assets and a routed legacy Binder directory, the current directory is enumerated first, but any later readDir failure on the legacy directory reaches the outer catch and returns [], discarding the IDs already collected from the healthy current directory. Callers such as library backup then silently omit all current Binder assets because one legacy location was temporarily unreadable. Handle each directory failure separately or propagate an incomplete-listing error instead of replacing the accumulated result with an empty list.

When legacy auxiliary cleanup fails and the app is restarted before retrying, this removal has already deleted the project.json metadata needed to reconstruct the route, while the retained policy exists only in FsCore's in-memory map. The next deleteProject call sees no main directory and no policy, reports success, and permanently leaves the legacy Binder/Codex files orphaned. Fresh evidence in the final tree is that strict cleanup now surfaces the failure, but the only durable routing record is still removed before that cleanup begins; retain that record durably until all routed deletions succeed.

When a missing-ID legacy project is renamed and saved, the save correctly persists __worldscriptLegacyProjectDirectory, but after an app restart this condition compares the loaded directory with the new title and therefore declines to re-add the directory to verifiedLegacyProjectDirectories. The next edit/autosave ignores the persisted directory marker and creates a second project under the renamed title, leaving the original path stale and splitting the project's filesystem identity. Revalidate the persisted marker against safeProjectId instead of requiring the current title to still derive the original directory.

When an invalid-ID legacy snapshot is restored without first loading its project, resolveLegacySaveIdentity verifies the existing Binder/Codex evidence and this branch persists the resulting routing metadata, but it never registers the same policy in FsCore. For the rest of that session, Binder reads miss the verified legacy directory and Codex autosaves can write a second copy under the normalized directory; after restart the persisted policy routes back to the old copy, making those new Codex updates disappear. Register the verified policy immediately when applying this metadata.

When restoring an earlier snapshot for a desktop project whose legacy ID is unusable, the snapshot is expected to differ from the current project.json; this whole-project equality check therefore rejects the save, and the subsequent autosave/close-time flush cannot persist the restored state. Fresh evidence beyond the earlier snapshot finding is this newly added content comparison, while the regression test only snapshots content identical to the current file; validate durable ownership or provenance without requiring all mutable project content to match.

When a desktop profile contains snapshots from multiple projects, the Settings snapshot list is global and FsSnapshotStore stores no separate owner metadata, yet this code discards the selected snapshot's id without comparing it to targetDirectory. Selecting a snapshot created for project B while project A is active therefore grafts B's entire content onto A's ID; the fulfilled thunk installs it as A and the next autosave overwrites A's project file. Validate compatible snapshot ownership before replacing its identity, with an explicit legacy-ID exception where necessary.
