A wrapper reporting a component 'down' can be lying: confirm with the component's own check before trusting a proxy's status

Adhoc cdhash-only signing orphans TCC/entitlement grants on every rebuild and SIGKILLs sandboxed apps

An Unverified Blocker Is a Fabrication: Probe Every 'NEEDS YOU' Gate

Behavior lives in the daemon, not the web deck

Local main can silently fork from origin (unpushed + unpulled commits)
intermediate · 5 min
Make the Agent Earn the Word "Done" With a Receipt
intermediate · 6 min
Never prune the data your engines learn from, and never use a banned feed: archive bars append-only so the system warm-starts from history instead of booting cold

One Agent Only: Why Parallel Writer Fan-Outs Spray Duplicate Work and Leave Mid-Edit Breakage

Runtime knobs that live only in the launchd plist won't travel with the repo
