CoreScope 0.9.0

Added

• Performance audit: MCP performance_audit sweeps what CoreScope already knows and ranks
  what the user could stop, remove or turn off — orphans, heavy apps and processes, stuck or
  power-hungry agent sessions, started profiles, idle and stopped containers, reclaimable space from the
  cached Cleanup scan and plan, folders Disk growth saw grow, Services checks that are always down,
  and CoreScope's own costliest switches (collector interval, floating panel, Codex and Claude live
  limits). Each finding carries what it would give back (CPU, memory, disk, watts), how sure
  CoreScope is, and the tool and arguments that act on it; the audit never acts, never scans the
  disk, and lists stale sources with the tool that refreshes them. Ranking weighs whatever is tight
  right now (memory pressure, a nearly full disk, battery). The top findings also show on the
  Overview as To lighten the Mac, each row opening the page where to act.
• Remove unused Docker volumes from the Containers page: a trash button per volume and
  Remove unused… for all of them, each behind a confirmation that names the volumes, their sizes
  and that the data is deleted for good. Only volumes no container references (running or
  stopped) can be removed; volumes in use say by which containers, and the core re-checks right
  before DELETE /volumes/{name} (never forced) over the same local socket. Per-volume results,
  then the list refreshes. Rows show when each volume was created, anonymous (64-hex) volumes and
  what the labels say made them (compose project and volume), and database-like volumes
  (MySQL/PostgreSQL/Redis) warn that no snapshot is possible without a container. MCP
  list_volumes and remove_volumes (a dry run unless confirm: true; in-use volumes are
  always refused).
• Projects › Remove unused worktrees and branches: Remove unused… on each repository's card
  (Branches and Worktrees sections, card menu) opens a confirmation listing exactly what goes —
  linked worktrees whose branch is merged into the default branch, whose upstream is gone or whose
  folder is gone, and local branches merged into the default branch — with path, branch, size, why
  each qualifies and a checkbox per item. Never the main or current working tree, a worktree a
  process works in, a locked one, or a branch checked out in a worktree that stays; a worktree
  with uncommitted changes is shown and skipped unless a separate option (off by default) allows
  --force. A merged branch can go together with its worktree. Uses git worktree remove and
  git branch -d (never -D); the core checks every item again against fresh state before
  removing and reports each result (removed, refused with the rule, or git's error). MCP
  project_unused (dry run with reasons) and project_remove_unused (same rules, never forced or
  dirty).

Changed

• Services tell "not running" apart from "down": checks are grouped by project (checks added
  in the app in their own group) with a per-group summary. A check from a project's
  .corescope.yml whose profile is not running and whose port nobody listens on is gray "not
  running", with a Start button for the profile; while the app is off it is not probed at all
  (checking resumes when the profile starts or the port opens), no longer counts against uptime
  and sends no down notifications; red is kept for what should be up (profile running, port listening but
  failing, checks added by hand). The tooltip explains each state. Checks and whole groups can be
  paused. MCP list_services / check_services report status (up, answered_with_error,
  down, not_running, paused, not_checked_yet), group, monitored and explanation; new MCP
  pause_service.
• The Worktrees and Local branches sections group their rows into In use, Removable and
  Other, show the removable count and size next to the title, collapse long groups, and share
  badges (merged, upstream gone, in use) in the same order and colors.

Install

1. Download CoreScope-0.9.0-macos-universal.dmg below (universal: Apple Silicon and Intel, macOS 14+).
2. Open the DMG and drag CoreScope to Applications.
3. The app is open source and signed ad hoc, not notarized by Apple, so macOS blocks it the first time. Open it once, then go to System Settings → Privacy & Security and click Open Anyway. Alternatively, in Terminal:

   xattr -dr com.apple.quarantine /Applications/CoreScope.app

The Intel slice is built and checked on every release but has not yet been run on an Intel Mac; reports are welcome.
