Three faults from one agent-managed onboarding (env-dev-08, 2026-09-09), each of which pointed
the diagnosis away from the actual fault.
1. install.sh granted the agent's read on the ziti identity with a POSIX ACL. ziti-edge-tunnel
rewrites that file on a controller config update and the rewrite drops the ACL: the agent
applied cleanly at 01:21 and was failing every tick by 01:32. Group membership survives the
rewrite (the file stays ziti:ziti 0640), so install.sh and the package postinstall now add
monky-deployd to the `ziti` group, and a default ACL on the identity directory carries the
grant onto a newly created file. The explicit ACLs stay for the boxes that need them.
2. openziti.load() accepts an unreadable or malformed identity: the C SDK logs "configuration is
invalid" and returns a context that only fails at dial, as a bare TypeError, which the
transport reported as a missing intercept or a policy gap. The SDK transport now reads and
parses the identity itself and names the real fault first.
3. The disk pre-flight ran only when the bundle declared disk_need_bytes, so a bundle without one
died mid-pull with containerd's "no space left on device" — which reads as a registry fault.
A bundle that declares no size now has to clear the headroom floor, and the pre-flight measures
containerd's root as well as the docker data-root: docker 29 keeps image layers in the
containerd image store, and on env-dev-08 those sat on different filesystems (93 GiB free where
the agent looked, 2.8 GiB where the pull wrote).

install.sh wrote tenancy.port 8081 (the in-pod port) but the
monky.tenancy.deploy intercept is 443, so the SDK found no intercept and the
check-in failed with 'service not available' followed by the SDK's bare
TypeError. Also wrap non-OSError SDK failures in a TransportError that names
the host:port and what to check.
