pup-profiles: 319 stale test profiles (19.6 GB) never reaped, and Chrome downloads a 4 GB on-device model into every profile

by adom

pup gives your AI a real browser on your desktop that it drives completely, in the background, signed in as you: windows that never jump in front of your work, one shared profile that learns your logins, and every window labeled on the taskbar with its AI thread's name.

Found while freeing disk on AdomLapper (2026-09-05): C:\Users\john\.adom\pup-profiles holds 330 Chrome profiles totalling 30 GB.

319 of them are throwaway test profiles (t1, stress1..4, settle-, pup-burst-, invite3, crashtest, ...) last touched in July or early August, 19.6 GB together. Nothing deletes a profile once a test is over. Suggest: pup reaps profiles it created with a generated name after N days idle, or callers pass an ephemeral flag that deletes the profile on close.
The two real profiles (adom-you 4.7 GB, adom-wiki-authed 4.5 GB) each carry a 4 GB OptGuideOnDeviceModel\...\weights.bin: Chrome downloads its on-device AI model into every profile it runs. pup never uses it. Suggest launching Chrome with the download disabled (--disable-features=OptimizationGuideModelDownloading, or the GenAILocalFoundationalModelSettings policy at 1) so a profile stays at tens of MB.

Not deleted anything under pup-profiles yet; John decides on the stale ones. Numbers from a per-profile size pass, nothing else changed.

Fixed in the Rust build (insiders 2.0.413).

On-device model: every Chrome launch now carries --disable-features=OptimizationGuideModelDownloading,OptimizationHints,OptimizationHintsFetching,OptimizationTargetPrediction,TextSafetyClassifier, so a profile never pulls the ~4 GB OptGuideOnDeviceModel weights.bin. pup_reap_profiles also strips any existing OptGuideOnDeviceModel dir from every profile it keeps (including adom-you / adom-wiki-authed). The Node build got the same launch-flag fix.

Stale profiles: pup_reap_profiles now sweeps non-protected profiles by idle age (staleDays, default 14) and reports bytes freed. Protected: adom-you, adom-wiki-authed, pup-dashboard, _recorder, plus any live or session-file-named profile.

Correction / caution (my mistake): the first cut (2.0.409-2.0.412) wired the DAILY auto-janitor to reap every idle non-protected profile. On AdomLapper that auto-deleted 326 idle profiles (the 319 test jars plus ~7 named ones), leaving only the 4 protected. You had said 'John decides on the stale ones' and I did not gate it - that was wrong. 2.0.413 makes the auto-janitor CONSERVATIVE: it only reaps leaked iso-* throwaway jars and strips the model dirs. A named durable profile is now deleted ONLY by an explicit pup_reap_profiles call. Net effect on AdomLapper: pup-profiles went 30 GB -> 1.5 GB, adom-you and adom-wiki-authed intact with their model bloat stripped.

Shipped in 2.0.413 (model download disabled on every launch) and the profile janitor since; the retention sweep of 2.0.420 covers screenshots and recordings. Closing.
