- Around line 608-616: Update ItemFormComponent.loadPosterPreview and the
corresponding ItemCardComponent preview-loading flow to track destruction with
DestroyRef.onDestroy, revoke the active object URL during teardown, and guard
late getUrl results by revoking them instead of assigning after destruction.
Apply the changes at src/app/components/item-form/item-form.component.ts:608-616
and src/app/components/item-card/item-card.component.ts:81-94.
- Around line 573-605: The poster workflow in importPosterUrl, uploadPoster, and
clearPoster must track request order and persisted draft image IDs: apply only
the latest asynchronous result, delete superseded drafts when replacing or
clearing, remove all tracked drafts when canceling, and retain a draft ID only
after successful submission. Coordinate the state with the existing form
submission and cancellation handlers without changing unrelated poster behavior.
In `@src/app/services/import-export.service.ts`:
- Around line 44-51: The import flow in the portable and legacy branches must be
failure-atomic across imageStorage.replaceImages and storageService.importData:
validate the complete payloads before any destructive write, then use an
existing coordinated transaction/commit mechanism or capture and restore both
stores on failure so neither store is left partially updated. Preserve support
for both portable exports and legacy payloads.
In `@src/app/services/watch-list.service.ts`:
- Around line 57-65: Update StorageService.saveData to return its persistence
promise, then await that promise in the item replacement flow around saveData
before deleting previousPosterId. Apply the same sequencing in
src/app/services/watch-list.service.ts lines 88-93: await successful item
deletion before deleting removed.posterId; leave cleanup skipped when
persistence fails.

preserve the existing submission flow once poster storage has completed.

- Around line 50-78: Update importDataWithImages so it cannot overwrite a newer
saveData mutation while its queued transaction is pending: publish the imported
snapshot before enqueueing the write and restore the prior state only if this
import fails and no newer mutation has been published, or implement an
equivalent revision check. Keep the queued IndexedDB transaction and persistence
bookkeeping intact, and ensure a later mutation remains the published data.
In `@src/app/services/watch-list.service.ts`:
- Line 103: The fire-and-forget calls to updateItem in WatchListService discard
rejected promises, causing unhandled rejection reports when persistence fails.
Attach a rejection handler to every listed updateItem call site, or route them
through a shared helper that reports failures, while preserving the existing
update behavior.

376-388: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winAssert the rendered submit control.
If this test is intended to cover the UI disabled state, run change detection and assert
button[type="submit"].disabled. The current test checks the signal and event suppression only. A template binding regression can pass. This recommendation uses the suppliedItemFormComponent.submitcontract.Suggested assertion
fixture.componentRef.setInput('groups', groups); + fixture.detectChanges(); fixture.componentInstance.updateTitle('Test Movie'); ... fixture.componentInstance.posterLoading.set(true); + fixture.detectChanges(); + const submitButton = fixture.nativeElement.querySelector( + 'button[type="submit"]', + ) as HTMLButtonElement; + expect(submitButton.disabled).toBe(true); fixture.componentInstance.submit();🤖 Prompt for AI Agents

27-35: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winCover rejected poster downloads.
The mock always resolves
storeUrlandstoreFile. The PR reports HTTP 504 failures for remote poster downloads, but the changed tests do not exercise a rejectedstoreUrl. Add a test that verifies loading ends,posterIdis not incorrectly assigned, and the user can retry without an unhandled rejection. This recommendation uses the reported HTTP 504 failure in the PR objectives.🤖 Prompt for AI Agents

356-358: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winUse a deterministic completion signal.
Both tests flush exactly two microtasks with
Promise.resolve(). This depends on the current internal promise chain. An added asynchronous step can make the assertion run before poster storage or cleanup completes. Await the component operation directly, or verify that the Angular fixture stable-state helper tracks these promises. This recommendation uses the supplied Angular/Vitest test context.Suggested wait replacement
- await Promise.resolve(); - await Promise.resolve(); + await fixture.whenStable();resolvePoster('late-poster'); - await Promise.resolve(); - await Promise.resolve(); + await fixture.whenStable();Also applies to: 390-415
