Parley v0.1.19 — unnotarized test beta

Parley v0.1.19

This test beta adds reviewed command runs in new Shell panes, clearer approval
prompts, broader title-bar double-click support, and Status Center history
management. It continues the ad-hoc, unnotarized test-beta channel.

Reviewed command runs

• Agents can propose a noninteractive test command with exact arguments and a
  working folder using parley request-run. Parley shows an editable native
  preview and creates a new visible Shell pane after approval.
• The approved command runs as you, outside the agent boundary and vendor tool
  enforcement. Arguments are passed directly to the executable. Existing Shell
  panes never receive agent input.
• Per-run approval is the default. Optional Auto-approve this command for this
  session applies to the exact arguments, canonical folder and requesting pane
  generation. It is off by default, visible and revocable. The command can run
  project code that agents change and can access your files and other pane
  credentials; exact arguments do not limit which code can execute.
• Restarting or moving the requesting pane, changing its folder or policy,
  Stop Everything and quit invalidate session trust. Trust is never restored
  from saved history.
• Captured stdout, stderr and exit status return to the requester with bounded
  output. These are command results, not a Parley test verdict. The completed
  pane remains an ordinary Shell.
• Only one active run is allowed per requester. Native cancellation and late
  result recovery retain the owned process and request identity.
• New foreground requests open their approval preview when the workbench can
  present it. Background requests request Dock attention. A visible
  Approval required banner keeps deferred requests easy to find without
  interrupting an existing dialog or repeatedly reopening a dismissed preview.
• Ghostty checks that cannot run inside an agent boundary now explain that they
  require a human Shell pane, rather than opening repeated failed terminals.

Window and appearance fixes

• Double-click the blank native title bar or the wide blank toolbar area to
  apply the system title-bar action. Minimize and Do Nothing are respected;
  Fill uses standard window zoom.
• Toolbar controls and terminal content retain their existing interactions.
• Selected pane headers use the correct native background in light mode.

History management

• Status Center has a visible Clear history… button following the selected
  workspace scope, including All Workspaces.
• The confirmation names the scope. Clearing removes finished handoff records,
  their returned or captured results, and recorded activity, including hidden
  or dismissed records. All Workspaces includes history for removed workspaces.
• Active handoffs and command workers remain. Late command output cannot
  recreate a cleared history record, and retry protection remains intact.
• History → Manage history… brings together search, a Command runs
  filter, retention controls, and export of selected records or the loaded scope.
  Retention applies the same 100, 250 or 500-record limit separately to handoffs
  and activity across workspaces. Lowering it requires confirmation.
• Clearing and retention affect only the current local Production or Development
  runtime; they do not stop running panes.

Upgrade and install

• Quit Parley before replacing the application. Quitting ends live pane
  processes and the app-resident coordination core; workspace definitions,
  layouts and retained collaboration history remain after upgrading.
• The shared protocol is now v19. Explicitly start your agent panes after
  upgrading to receive the reviewed command-run instructions. Launch stamps
  remain configuration evidence, not proof that a vendor retained instructions.
• Download Parley-0.1.19-mac-arm64.dmg, replace Parley.app in Applications,
  and reopen it from Finder on a supported Apple Silicon Mac.
• This test beta is ad-hoc signed and not notarized. Use the documented
  System Settings > Privacy & Security > Open Anyway flow only for files
  from this expected GitHub release. Never disable Gatekeeper globally.
• This beta does not publish a stable Sparkle appcast or Homebrew cask.
• Verify downloads with Parley-0.1.19-mac-arm64.SHA256SUMS. The release includes
  the standalone report from the required 25-round eight-pane Ghostty soak.
