Quarantine & restore

Where it lives

~/.local/state/bleach/
├── journal.jsonl                        # append-only; every mode, including delete
└── quarantine/
    └── 20260917-114203/                 # batch id = timestamp
        ├── manifest.json                # original paths, sizes, tiers, reasons
        ├── Library-Caches-lens-desktop-updater
        └── .local-share-opencode-bin

The directory is created lazily on first apply. Stored names are the original path with / flattened to -, so the quarantine stays browsable by hand — if bleach itself ever breaks, you can put things back with mv.

Batch IDs are timestamps, so they sort chronologically.

Restoring

bleach restore                      # the most recent batch
bleach restore 20260917-114203      # a specific batch
bleach restore 20260917-114203 --path /Users/you/.cache/opencode   # one path

--path is repeatable, so you can pull back just the one thing that broke without undoing the whole batch.

It never clobbers

If the app recreated its directory after the removal, restore skips that entry rather than overwriting:

  restored 45 paths from batch 20260917-114203
  skip  /Users/you/.cache/opencode — destination already exists

Which copy wins is your decision, not bleach's. The quarantined copy stays where it is until you deal with it.

Purging

This is the only code path in bleach that destroys data, and it only ever touches paths inside its own quarantine directory.

bleach quarantine --purge                        # preview: batches older than 30 days
bleach quarantine --purge --yes                  # do it
bleach quarantine --purge --older-than 7 --yes   # different threshold
bleach quarantine --purge --all --yes            # everything, regardless of age

Without --yes it prints what would go and stops:

  20260917-114203    11.6G   46 paths

  This permanently deletes 11.6G and cannot be undone.
  Re-run with --yes to confirm.

Space accounting

A quarantined path still occupies disk — it was renamed, not removed. du on your home directory won't change until you purge.

That's the trade: you get a window in which everything is reversible, at the cost of not seeing the space back yet. If you'd rather have the space immediately, use --mode delete and rely on having read the plan.

A suggested rhythm

bleach scan --tier orphan          # look
bleach plan -o plan.json           # write
less plan.json                     # read
bleach apply plan.json --yes       # quarantine
# …use your machine normally for a week…
bleach quarantine --purge --all --yes   # commit

If something breaks in that week, bleach restore puts it back and you've lost nothing.
