- Update now stopped the daemon and failed with "Bootstrap failed: 5: Input/output error" on macOS, leaving the agent's plist written and no job loaded. `launchctl bootout` returns once the daemon has been sent SIGTERM, and launchd refuses `bootstrap` until the daemon has exited and the job has left the domain. - Installing or replacing the launchd agent now waits for the booted-out job to leave, for up to 25 seconds, which covers the 20 seconds launchd allows before SIGKILL. - Starting the service now loads the agent's plist first when launchd does not hold the job, so the window's Start button and `service start` recover a registration left unloaded instead of failing in `kickstart`. - The stand-in launchctl in the service lifecycle test returns from `bootout` while the daemon is still stopping and refuses `bootstrap` until it has gone, as launchd does, so `service install --start` over a running daemon pins the regression. |

Specifications
One spec per capability, numbered by topic. Each holds its user stories, requirements, success criteria, research and tasks; the architecture, the daemon contract and the command-line contract are in 001, and every spec follows the constitution.
Requirement (FR), success criterion (SC), research (R) and task (T) numbers are unique across every spec, and the code cites them by number. They were given in the order the work was done, so one spec's numbers are not contiguous; the lists below say which spec holds each. The one exception is 014, whose task list started again at T001: its T001 to T034 are cited as 014's.
| Spec | What it covers |
|---|---|
| 001-service-and-clients | The single executable, the daemon, the gRPC contract, the command line, installing the service, packaging; the architecture and the original input |
| 002-configuration | The configuration file, applying changes while running, export and import, Apple's setup, capabilities |
| 003-virtual-ports | Ports applications on one computer use to talk to each other |
| 004-hardware-devices | Attached MIDI hardware and other applications' ports, hot-plug, identity |
| 005-network-ports | RTP-MIDI between computers: discovery, invitations, the journal, machines, the automatic port |
| 006-bluetooth-midi | Bluetooth LE MIDI, connecting out and advertising |
| 007-routing | Routes between any two endpoints, loops, system-exclusive, the repeater |
| 008-resilience | Recovery: backoff, sleep and wake, releasing notes, restoring state, the MIDI service dying |
| 009-observability | State, counters, history, the monitor, the diagnostic report |
| 010-graphical-interface | The libcosmic window and its redesign |
| 011-midi-service-crash-warning | Warning that other apps may have lost MIDI; when traffic last moved each way |
| 012-test-note | Sending a note out of an endpoint to test what listens |
| 013-windows-support | Windows as a first-class platform |
| 014-mac-app-store-mode | The sandboxed App Store build, run from the menu bar |
| 015-mac-menus | The menus on macOS: File, Edit, View, Window and Help |
| 016-app-store-submission | Building the package App Store Connect takes |
| 017-appimage | The AppImage for Linux, and registering the daemon from it |
| 018-remembered-machines | Machines a network port connected to: forgetting old connections, following a session that moved, proving which port a session is; answering Apple over a link-local address |
| 019-daemon-updates | Telling that the daemon is another build than the window, and updating it when asked |
