VLC HTTP status (enabled by harness, password unknown to agent): rate=1.5, time=150 ±3 s, state=paused, active SPU track = English. The agent has no terminal, so VLC command-line flags and the rc/Lua interfaces are not reachable; state must be set in the running VLC window.

Proposed partial credit

30% rate; 40% position; 20% subtitle; 10% paused.

R12.07.01.01-T03 Remove all songs by one artist from a large playlist

Original instruction

In the Navidrome web player, remove every track by 'The Weekend Band' (not 'The Weeknd') from the playlist 'Favorites' (420 tracks), keeping everything else and the original order.

Proposed verifier

Navidrome DB: playlist tracks = original minus that artist's 14 tracks, order of the rest unchanged; The Weeknd tracks still present. The agent has no terminal and browser devtools are disabled, so the Subsonic/native API is not reachable outside the player; the server log must attribute edits to the web client (c=NavidromeUI).

Proposed partial credit

60% all target tracks removed; 25% no wrong removals; 15% order preserved.

R12.07.01.01-T04 Build a playlist from tagged tracks over four minutes long

Original instruction

In the Jellyfin web client music library, create playlist 'Calm' with all tracks tagged genre 'Ambient' longer than 4:00, sorted by duration descending.

AntennaPod DB: 3 feeds; feed preferences: Tech Weekly speed 1.3, Daily News auto-download on with episode cleanup 3; played flags on episodes before 09-01 for Tech Weekly only. The agent has no adb shell or push, so the AntennaPod DB is not reachable; settings must be made in the app and the OPML imported through its file picker (harness input log).

Proposed partial credit

20% import; 25% speed; 25% auto-download cleanup; 30% played flags.

R12.07.01.01-T06 Find the timestamp where a slide title first appears in a lecture video

Original instruction

In VLC on macOS, open fixtures/lecture.mp4 (58 min) and find the first time the slide titled 'Backpropagation' appears. Create a VLC bookmark at that time named 'Backprop' and write the timestamp (mm:ss) into answer.txt.

answer.txt within ±5 s of ground truth 12:41; VLC bookmark (saved in playlist .xspf on quit or via status) at that time ±5 s with name. The agent has no Terminal and no ffmpeg or OCR tools, so the video cannot be scanned by script; the bookmark must be created in VLC's Bookmarks window.

Proposed partial credit

70% timestamp; 30% bookmark.

R12.07.01.01-T07 Fix album artwork and metadata for a ripped album in Music

Original instruction

In the Music app on macOS, the album 'Blue Train' was imported with track numbers missing, disc split into two albums, and no artwork. Merge it into one album (set album artist), set track numbers 1-5 per fixtures/tracklist.txt, and add fixtures/cover.jpg as artwork for all tracks.

Track files' ID3/MP4 tags: album, album artist, track numbers exact; embedded artwork hash equals cover.jpg (re-encoded allowed: perceptual hash distance <= 4); library shows 1 album. The agent has no Terminal or Script Editor (osascript blocked), so Music's AppleScript dictionary and tag tools are not reachable; tags must be edited in Music's Info window.

Proposed partial credit

30% merged album; 40% track numbers; 30% artwork.

R12.07.01.01-T08 Sort an artist's songs by duration and save as a playlist in a mobile music app

Android MediaStore playlist 'Long Floyd' with 10 tracks = top-10 longest Pink Floyd tracks, order descending. The agent has no adb shell, so MediaStore cannot be written by content commands; the playlist must be made in Retro Music, as the harness input log confirms.

Proposed partial credit

60% correct set; 30% order; 10% name.

R12.07.01.01-T09 Clean up Watch Later by removing mostly watched videos

Original instruction

In the PeerTube web client (test account), remove from the 'Watch later' playlist every video already watched more than 90% (watch progress bar on thumbnails), and move the remaining videos so the shortest is first.

Proposed partial credit

50% correct removals; 40% order; 10% no extra removals.

R12.07.01.01-T10 Merge a roommate's texted songs into a shared road-trip playlist

Original instruction

On the Android emulator, the 'Roommate' SMS thread (Messages) contains song suggestions in free text over the past week (some duplicates and one retracted). In the Spotify-style app clone, update playlist 'Road Trip' to include all suggested songs not already in it, excluding the retracted one.

Playlist tracks = original ∪ suggested − retracted, no duplicates; track ids exact (versions disambiguated by artist named in text). The agent gets screen input only (no adb shell, no backend API token), so the playlist must be edited in the app; the harness input log confirms UI taps.

Proposed partial credit

60% suggestions added; 20% retraction respected; 20% no duplicates.

R12.07.01.01-T11 Extract a frame at a timestamp and use it as a slide background

Original instruction

On Ubuntu, take a snapshot of fixtures/promo.mp4 at 00:08 using VLC's snapshot feature, then set it as the background image of slide 2 in deck.odp in LibreOffice Impress and save.

Proposed verifier

deck.odp slide 2 background fill is a bitmap with SSIM >= 0.95 to the ground-truth frame at 8.0 s ±0.1; other slides unchanged. The agent has no terminal, ffmpeg or Python, and LibreOffice macros are disabled, so the frame must come from VLC's snapshot and the background must be set in Impress.

Proposed partial credit

50% correct frame; 40% set as slide 2 background; 10% others unchanged.

R12.07.01.01-T12 Configure a smart playlist with nested rules in Music

Original instruction

In the Music app on macOS, create a smart playlist 'Fresh Rock' matching: genre contains 'Rock' AND (date added in the last 30 days OR play count is 0), excluding tracks rated 1 star, limited to 50 items selected by most recently added, live updating on.

Proposed verifier

Library XML smart criteria blob decoded: nested rule structure equals spec; limit 50 by date added; live updating; resulting membership equals reference evaluation. The agent has no Terminal or osascript and the library XML is read-only to it, so the smart playlist must be built in Music's rule editor.

Proposed partial credit

50% rule logic incl. nesting; 30% limit and selection; 20% resulting membership.

R12.07.01.01-T13 Set subtitles delay and style to sync a foreign film

Original instruction

In VLC on Windows, open fixtures/film.mkv with external subtitle film.en.srt which is out of sync. Determine the offset by matching the first spoken line to its subtitle, set the subtitle delay so they align (within 100 ms), and set subtitle font size to 'Large' with a background box. Save the delay into a corrected film.en.synced.srt via the subtitle track sync tool.

film.en.synced.srt timestamps shifted by ground-truth offset ±100 ms; VLC prefs (vlcrc): freetype size large, background opacity > 0. The agent has no terminal or Python, and file writes by other processes are flagged by the file audit log, so the synced SRT must be saved from VLC.

Proposed partial credit

60% sync accuracy; 25% saved SRT; 15% style prefs.

R12.07.01.01-T14 Organize a podcast queue by priority and set a sleep timer

Original instruction

In Apple Podcasts on the iOS Simulator (local test feeds), build the Up Next queue in this order: newest 'Daily News', then the two oldest unplayed 'History Hour' episodes, then 'Tech Weekly' episode 212. Set a sleep timer for 'End of episode'.

Podcasts app DB: queue episode GUIDs in exact order; sleep timer mode=end_of_episode. The agent drives only the Simulator window: it has no shell on the host (simctl and the app container are not reachable), so the queue must be built in Podcasts.

Proposed partial credit

60% queue contents; 25% order; 15% sleep timer.

R12.07.01.01-T15 Deduplicate a music library while keeping the highest-quality copy

Original instruction

In the Music app on macOS, the library has 38 duplicate tracks (same title/artist/duration ±2 s) from two imports: AAC 256 kbps and MP3 128 kbps. Delete the lower-bitrate duplicates from the library (move files to Trash), (play counts need not be merged). Do not delete live/remix versions.

Library and Trash: the 38 MP3 duplicates removed; all AAC copies present; 6 decoy live/remix tracks with same titles retained. The agent has no Terminal or osascript, so Music's AppleScript dictionary is not reachable for scripted deletes; removals must be made in Music.

Proposed partial credit

60% duplicates removed (proportional); 30% decoys kept; 10% high-quality copies intact.

R12.07.01.01-T16 Report a speaker's on-screen name at a timestamp at a given speed with captions

Original instruction

In the PeerTube web client, open the video 'Panel: Open Data 2026', set speed to 1.5x and turn on English captions, then report the name shown in the lower-third caption at 03:00 and the first caption line displayed after 03:00.

Proposed partial credit

30% BPM range; 40% adjacency constraint; 15% crossfade; 15% export.

R12.07.01.01-T19 Migrate playlists from one music server to another preserving order

Original instruction

Move the 5 playlists from the Navidrome instance to the Jellyfin music library. Track files are identical but IDs differ; several tracks have slightly different titles (e.g. '(Remastered)'). Recreate each playlist in Jellyfin with the same order and report any track that could not be matched.

R12.07.01.01-T20 Set up a family media server with per-user libraries, ratings limits and subtitle defaults

Original instruction

In the Jellyfin web admin, create users 'Kids' and 'Guest'. Kids: access only to 'Family Movies' and 'Cartoons' libraries, max parental rating 'PG', subtitles default English forced-only; Guest: Movies library only, no downloads, no transcoding above 1080p. Then fix 3 films in Family Movies whose official rating is missing (set from fixtures/ratings.csv) so the Kids filter works.
