Addressed Issues:

Fixes #1485 : Folder Deletion dosen't delete memories that were made from that folder.

Problem Statement: Deleting a folder from Settings, removes the folder's images from the library,
but any auto-generated Memories built from those images are left behind as empty,
broken tiles instead of being removed.

Screenshots/Recordings:

Additional Notes:

Reason for Changes:

There's a memories table separate from the images table. Each memory has links to the photos it's made up of. When you delete a folder, its photos get deleted from the database, and that correctly cascades to remove the links between those photos and whatever memory they belonged to.

But nothing ever goes back and checks the memory itself afterward. So the memory row just sits there forever, still marked "complete," with zero photos attached.

  1. Dead Code: there's already a function for exactly this, db_prune_empty_memories(), that marks a memory "empty" once its photo count drops too low. It's fully written, and it even has its own passing tests. Nobody ever calls it. It iss a dead code.

  2. Deleting a folder doesn't trigger any memory recalculation at all — adding a folder does, syncing does, toggling AI tagging does, but delete was just skipped.

Files Changed : 4 (2 test files, 2 main backend files)

1. app/utils/memory_curator.py:

from app.database.memories import (
    db_delete_stale_memories,
    db_prune_empty_memories,
    db_get_video_candidates_in_period,
    db_get_video_scoring_signals,
    db_finish_memory_run,
Added this `db_prune_empty_memories ` It was already present as a dead code.
 try:
            emptied = db_prune_empty_memories(preferences.min_images)
            if emptied:
                logger.info(f"Marked {emptied} memories empty (images/folders removed)")
        except Exception:
            logger.error("Failed to prune empty memories", exc_info=True)

Added this in memory_curator_run function.

2. app/routes/folders.py:

def delete_folders(
    request: DeleteFoldersRequest, app_state: State = Depends(get_state)
):

changed this : def delete_folders(request: DeleteFoldersRequest):

.

 # Deleted images/videos cascade out of memory_images/memory_videos,
        # which can leave memories pointing at nothing. Re-curate so those
        # get pruned instead of lingering in the grid until the next
        # unrelated add/sync/tagging run.
        executor: ProcessPoolExecutor = app_state.executor
        executor.submit(_curate_memories, "folder_delete")

3. Added required tests in test files.
a)backend/tests/test_folders.py
b)backend/tests/test_memory_curator.py

Passing Checks:

pytest
ruff check .

Summary:

Now, whenever you press regenerate after updating the folders in the folder management. The memories also gets updated on time of deletion.

Walkthrough

Folder deletion now prunes empty memories synchronously and queues background memory curation after successful deletion. Curation uses preferences.min_images. Tests cover threshold resolution, executor submission, and independent failure handling.

Changes

Folder memory cleanup

Layer / File(s) Summary
Trigger curation after folder deletion
backend/app/routes/folders.py, backend/tests/test_folders.py
delete_folders prunes empty memories before it submits _curate_memories("folder_delete"). Pruning and submission failures are logged with tracebacks and do not change the deletion response. Tests verify ordering, submission arguments, and both failure paths.
Prune empty memories during curation
backend/app/utils/memory_curator.py, backend/tests/test_memory_curator.py
memory_curator_prune_empty resolves min_images from preferences when needed and delegates pruning to the database. Curation uses this helper and continues when pruning fails. Tests cover explicit thresholds, preference-derived thresholds, and anniversary curation continuity.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 422b4

Folder deletion now triggers memory reprocessing, but the pruning logic can incorrectly remove memories that still contain videos or valid media, and failures in the asynchronous cleanup path may be hidden. The media-counting logic should be corrected before merging.

Assert the complete cleanup contract.

The success test does not verify db_prune_empty_memories(preferences.min_images). The submission-failure test does not verify that executor.submit was attempted. Add assertions for the pruning call, the configured threshold, and the "folder_delete" trigger.

The folder-deletion objective depends on synchronous removal of memories below the configured image threshold.

Mark memories empty once their live image count drops below the

route. Pass min_images when the caller already has preferences loaded
(memory_curator_run); omit it to have this fetch its own.

Prune memories only when no live media remains.

db_upsert_memory stores videos in memory_videos, not memory_images. The current query counts only images and uses < min_images, so it marks a complete memory as empty when a video or fewer-than-minimum images remain. Require zero rows in both association tables, and add regression tests.

In `@backend/app/utils/memory_curator.py` around lines 198 - 209, Update
db_prune_empty_memories, used by memory_curator_prune_empty, to mark a memory
empty only when it has zero live rows in both memory_images and memory_videos;
do not use the configured minimum image threshold for this decision. Add
regression tests covering video-only and below-minimum-image memories remaining
non-empty, plus memories with no media being pruned.

@Takitxt, the executor submission assertion is correct. It does not address this finding.

This finding concerns db_prune_empty_memories. The pruning logic must retain memories that contain live video rows or live image rows, even when the image count is below min_images. Please add regression coverage for video-only memories, below-threshold image memories, and memories with no media.

@Takitxt in the ui, the memories are being deleted before you confirm it. not a good UX

@SinghAman21 Yes i can see that. Currently i am working on the backend logic, after that i will fix the UX problem. Thanks for reviewing the PR. 😊
