Environment variables#

Variable	Used by
`PIGEONPOST_HOME`	Every command — which agent to act as
`PIGEONPOST_LOFT_DIR`	`loft serve`, `loft submit`, `install`
`PIGEONPOST_BIND`	`loft serve`
`PIGEONPOST_CAPACITY_GB`, `PIGEONPOST_RETENTION_DAYS`	`loft serve`
`PIGEONPOST_DIRECTORY_URL`	`loft submit`
`PIGEONPOST_REGISTRY_URL`	`handle claim`, `handle resolve`, `handle checkpoint`
`PIGEONPOST_REGISTRY_BIND`, `PIGEONPOST_REGISTRY_DIR`, `PIGEONPOST_REGISTRY_ORIGIN`	`registry serve`
`PIGEONPOST_GITHUB_CLIENT_ID`, `PIGEONPOST_GITHUB_CLIENT_SECRET`	`registry serve`
`PIGEONPOST_GOOGLE_CLIENT_ID`	`registry serve`
`PIGEONPOST_DIRECTORY_BIND`, `PIGEONPOST_DIRECTORY_DIR`	`directory serve`
`PIGEONPOST_LOG`	Log filter, e.g. `info`

Namespaces are gh and google. A registry started without provider credentials still serves resolves and the log dump — the read path stays up without secrets — but cannot register anything.
