Unload the rejected bootstrap before rolling back
When the first bootstrap loads the label but its follow-up probe reports a background or unknown spawn type, the label remains loaded. Restoring the old plist and immediately calling bootstrap again therefore fails because launchd already owns that label, leaving launchd running the rejected cached definition while the file has been rolled back. Boot out the loaded failed attempt before bootstrapping the restored unit.

Handle forced refresh before the systemd all-units path
On Linux, refresh --name N --force enters this systemd branch before force is inspected, repoints every installed daemon rather than targeting N, emits no refresh_outcome=<token>, and can still exit 0. This contradicts the command's new help contract in help-daemon.txt:110-113; either reject --force on systemd or give it explicit single-daemon semantics instead of silently running the legacy all-unit refresh.
Useful? React with 👍 / 👎.

kcap daemon restartreload Adaptive launchd services.
DaemonCommands.RestartOneonly sendsDaemonRestartClient.RequestAsync(...). It does not call the service refresh path or reload the launchd job. When the target is launchd-managed and its loaded spawn type is Adaptive, the restart can leave launchd using the cached background-priority definition. Route this command through the launchd refresh logic, or do not claim this part of#1351is covered.🤖 Prompt for AI Agents

Closes #1351 — AI-3551
What & why
launchd keeps a service unit's
ProcessTypefrom the moment it loads the job. A daemon loaded as Adaptive, and every agent it hosts, runs in the background QoS band: terminal output and typing lag once a few agents work, andtaskpolicycannot lift it. The post-update refresh rewrites the unit to Standard but defers the reload whenever the daemon is busy, so a Mac that installed before that change stays throttled until its next restart.kcap daemon statusnow names the loaded band,kcap daemon service refresh --forcereloads one daemon with a machine-readable outcome, and the desktop app shows the condition in the rail with a consented Reload that ends the hosted agents.Where to look
Only a positive spawn type (
daemon,interactive) counts as success anywhere, including the app's post-reload classification: a bootstrap that exits 0 but still printsadaptiveis not a reload. The reload outcome is controller state rendered in the rail, never a message on the shared attention lane.Verification
launchctl print gui/501/io.kurrent.kcap.daemon.alexey:spawn type = adaptive (6), twelve hosted agents at background priority 4.
