Reference
The full command surface, the config file and its precedence, and the doctor checks and exit codes.
The exact surface: every command and flag, the config file with its layered precedence and env-reference rule, and what ari doctor checks, fixes, and returns.
CLI
Every ari command and the flags that shape a run: the TUI, headless -p, resume, and doctor.
Configuration
The config file, its layered precedence from defaults to flags, providers and tiers, and the rule that a key is always an env reference.
ari doctor
The checks doctor runs, which ones --fix repairs, and the exit-code contract for wiring it into CI.
