CoreScope 0.13.0

Changed

• The capacity gate admits or refuses at once instead of holding commands. The hook decides
  within 5 seconds: the command runs, or the agent reads why, the numbers and what to do; if
  CoreScope cannot decide in time the command runs and the failure is recorded. Blockers are
  transient (CPU, memory pressure: wait with wait_for_capacity) or structural (a full
  container VM, a container at its limit or stopped: do what it says; waiting won't help).
• Each heavy command says what it uses: a plain prefix runs on the Mac (CPU and memory);
  {command, uses: [cpu, memory, containers], containers: [...], weight} also checks the container
  VM and the containers it loads (running, below 90% of their own limit). Default PHP suites and
  Docker commands use containers. Existing .corescope.yml files keep working.

Added

• Admission queue shared by every session: admitted commands count as running while their
  processes live; at most max_parallel (by weight, default 2) at once, one heavy command per
  container, staggered admissions, earlier commands first; places expire when a session stops
  asking or ends. MCP reserve_capacity, release_capacity, capacity_events; system_capacity
  and wait_for_capacity take the command. The Agents page shows the queue with Run now and the
  latest decisions.
• corescope capacity-advice / MCP capacity_advice: reads the container VM and the
  project's containers (limits, use, missing limits, limits larger than the VM) and proposes the
  wait_for_capacity rule with what each heavy command loads.

Fixed

• Explicit waits that never end: wait_for_capacity stops at once on a structural blocker, and
  when max_wait_minutes passes it says not to run the command (instead of "go ahead").

Install

1. Download CoreScope-0.13.0-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.
