McRitchie Studio

Acceptance Criteria

• /devops shows a Worktrees & Slots panel below the test-suite catalog and stays admin-gated
• Panel renders the capacity band (floor / step / current / used / free / physical_max) from the registry
• Panel lists each worktree with app / branch / health / port linked to local_url / redis_db plus merged + dirty + cleanup-candidate badges and issue count
• Panel shows summary counts and generated_at with relative staleness
• A Refresh control re-runs the snapshot (refresh param) then reloads; on failure it degrades to the existing file with a staleness note and no 500
• Missing or unparseable registry degrades to an empty-state with no error
• Registry path is derived from Rails.root (projects-root .agents) with no hardcoded user path
• A request or controller test covers the panel rendering against a fixture registry
• Matches existing /devops Tailwind patterns; ruby -c and rubocop clean
• No regression to the test-suite catalog section

Expected Test Plan

• ruby -c on service/controller/test (PASS)
• bin/rails test devops_controller_test (PASS 5 runs 29 assertions 0 failures
• verified by Alex on ruby 3.3)
• rubocop on changed files (PASS no offenses)
• live /devops browser view owed to QA (no stack booted)
