Files Delete File

1. open Files (failed): Open Files to locate the exact MP3 in internal storage's Notifications folder.
2. open com.google.android.documentsui: The app-name lookup was ambiguous, so launch the Android Files document manager by its package ID.
3. tap “Navigation drawer”: Open storage roots to navigate to internal storage and its Notifications folder.
4. tap “Internal storage root”: The navigation drawer is open despite the no-effect notice. Select the visible internal storage root to reach Notifications.
5. tap “Notifications folder”: The storage root is already open; the Notifications folder is visible. Open it to locate the exact MP3.
6. tap “Search in Notifications”: The Notifications folder is open; search for the exact filename rather than revisiting the folder control or confusing date-prefixed files.
7. fill “Search filename” with “q2a8_fancy_banana.mp3”: Search the open Notifications folder for the exact filename before deleting it; the absence predicate is not yet established.
8. longpress “Exact matching MP3, right-hand tile”: The search shows both an edited look-alike and the exact filename. Long-press only the exact right-hand file to select it for deletion.
9. tap “Delete selected exact MP3”: The exact q2a8_fancy_banana.mp3 is the sole selected file, while the edited look-alike is not selected. Tap Delete to remove only the requested file.
10. tap “Confirm deletion of exact MP3”: The confirmation dialog explicitly names q2a8_fancy_banana.mp3; confirm deletion. The absence predicate is not yet proven while this dialog is open.
11. waitFor: Deletion is in progress and the exact file remains visible; wait for the operation to finish before evaluating absence.
12. tap “Back from search”: The exact filename still appears in search after deletion completed, so the absence predicate does not hold. Leave the search to refresh the Notifications folder listing and determine whether this is a stale result.
13. tap “Search Notifications folder”: The folder listing is refreshed but only the first files are visible. Search the exact filename again to establish whether it remains absent.
14. tap “Recent search query”: This is only a search-history suggestion, not evidence the file remains. Run the exact search in the refreshed Notifications folder to check whether the file is absent.
15. assertAI: The refreshed search for the exact name shows one result, explicitly labeled edited_q2a8_fancy_banana.mp3, with no other items above or below the viewport. This positively establishes that the exact file is absent while the look-alike remains.

Verdict: Step verified deterministically from the assertion outcome
