In `@app/src/main/java/app/gamenative/mods/AutomaticPlacementPlanner.kt`:
- Around line 470-482: The draft-assignment flow in candidateFromDrafts must
detect when multiple drafts for the same file.normalizedKey produce different
target keys before placedBySource overwrites an entry. Mark the source as
CONFLICTED and add a blocking issue for differing mappings, while preserving the
existing placement behavior when mappings agree.
In `@app/src/main/java/app/gamenative/mods/BethesdaPluginManager.kt`:
- Line 111: Update the plan-branch filter in BethesdaPluginManager to check the
extension of each file’s target rather than its source, so filtering matches the
plugin filename emitted from target.name while preserving the existing
pluginExtensions comparison.
In `@app/src/main/java/app/gamenative/mods/FomodEnvironment.kt`:
- Around line 43-48: Update FomodEnvironmentSnapshotBuilder.build and the
FomodPluginDependency evaluation logic to track whether plugin state was
inspected, using an explicit flag set whenever a game root is provided. Use that
inspection state instead of presentPlugins.isNotEmpty() so an
inspected-but-empty plugin set evaluates FomodRequiredFileState.MISSING as TRUE
while preserving UNKNOWN when no game root was supplied.
In `@app/src/main/java/app/gamenative/mods/ModConfigurationDraft.kt`:
- Around line 89-92: Update ModConfigurationDraftStore.write so temporary-file
creation, serialization, FileOutputStream.write, and fd.sync are all covered by
the existing runCatching flow; on failure, delete the temporary file before
propagating or recording the failure according to the current API, while
preserving the successful atomic persistence behavior.
In `@app/src/main/java/app/gamenative/mods/ModDeploymentJournal.kt`:
- Around line 72-103: The install health path must serialize deployment
reconciliation with the per-game lock used by applyInstallLocked. Update
checkInstallHealthForApp to invoke ModDeploymentJournalStore.reconcile within
ModDeploymentCoordinator.withGameLock(appId), ensuring reconciliation and its
checkpoint writes cannot race filesystem mutation or overwrite newer state.
In `@app/src/main/java/app/gamenative/mods/ModMaterializer.kt`:
- Around line 369-374: Update rollback handling around the plan.files cleanup to
remove the COPY_SENTINEL and clean newly created COPY directories after all
their child files are removed. Preserve the sentinel when rollback retains
changed files, and ensure deleteEmptyDirs can remove directories left empty by
the rollback.
In `@app/src/main/java/app/gamenative/mods/ModOwnershipManifest.kt`:
- Around line 95-101: Update the owned-file lookup in the planned decision
mapping around ownedBySourceAndTarget so it matches decisions using the shared
sourceRelativePath, targetRoot, and targetRelativePath fields instead of
comparing normalizedTargetKey. Preserve the existing fallback behavior only when
no composite match is found, ensuring multiple destinations for one source
restore the correct owned file metadata.
In `@app/src/main/java/app/gamenative/mods/NexusModManager.kt`:
- Around line 1226-1227: Update the tracked-install branch around
findingsForInstall to also run missingAppliedTargets for active installs not
represented in the overlay, while retaining the existing overlay findings and
verifyStale(ownership).issues. Ensure the fallback applies only when profile
state is absent or the active tracked install is uncovered, without duplicating
checks for installs already covered by the overlay.
- Line 913: Update deleteInstall to also remove the deployment journal for the
deleted install by calling a new ModDeploymentJournalStore.delete entry point
with the same cache root and installId used for ownership cleanup. Implement
delete to remove both the journal file and its temporary companion file,
preserving cleanup when the install is reimported.
In
`@app/src/main/java/app/gamenative/ui/component/dialog/NexusModsPlacementSections.kt`:
- Line 893: Update the LazyColumn row key in the groupRows items block to
include a unique stable per-file identity, such as the row index, in addition to
the existing group, source, target, and previousTarget fields; do not rely on
status alone.

- Line 97: Replace the overwrite-based copy in ModConfigurationDraft with an
atomic rename or backup-and-rename strategy so the existing valid record remains
readable if replacement fails. Apply the same change to the replacement logic in
ModDeploymentJournal, preserving the prior record until the temporary file has
been successfully promoted; update both listed sites accordingly.

- Line 1587: Update the SYMLINK validation condition around the target check in
NexusModManager so an existing target is accepted only when
Files.isSymbolicLink(entry.target.toPath()) is true; treat a regular file or
other non-symlink target as unhealthy and preserve the missing-target failure
behavior.

block before assigning selectedDestination: reject existing paths that are not
directories, while preserving valid new paths and existing directory behavior.
Ensure the confirm flow cannot save a regular file as targetRelativePath.

Description
This PR makes mod installation safer and more predictable across all games. Automatic placement, custom placement, FOMOD selections, reapplication, and mod ordering now use one canonical install-plan and materialization pipeline.
Added archive indexing and automatic destination inference based on game structure, recognized content roots, existing sibling folders, file types, and archive layout.
Expanded FOMOD parsing, option evaluation, conditional rules, file mappings, priority handling, and destination normalization.
Moved expensive planning and materialization work off the UI thread to prevent freezes and ANRs with large installers.
Added placement review, explanations, file browsing, paginated rules, clearer custom-placement controls, and more actionable validation messages.
Recording
N/A as this is nearly all logic, fixes, improvements, etc.

If I skip both, I accept that this change may face delays in review, may not be reviewed at all, or may be closed.CONTRIBUTING.md.Summary by cubic
Rebuilds Nexus mod installation so automatic placement, custom placement, FOMOD selections, reapplication, and mod ordering all run through one install-plan and materialization pipeline. Previously these paths had separate ad-hoc placement logic that could disagree and often froze the UI on larger installers.
