Module legacy 

Compatibility with installations made before the ProofVisor rename.

Releases before the rename read AV_* environment variables and looked for agentvisor.toml and ~/.agentvisor/. Existing deployments keep those names in systemd units, compose files and Kubernetes manifests, so an upgraded binary must still honour them. The new names always win when both are present.

Constants

ENV_PREFIX

Prefix of the environment variables now.

LEGACY_ENV_PREFIX

Prefix of the environment variables before the rename.

Functions

adopt_legacy_env

Copy every AV_* variable to its PV_* name when that name is unset, and say so on stderr (names only, never values).

existing_or_legacy

current if it exists, else legacy if that exists, else current. For default file locations that moved with the rename: an installation that still has only the old file keeps working, and a fresh one gets the new location.

legacy_env_adoptions

The PV_* names to set from AV_* variables, as (new name, value) pairs. A legacy variable is adopted only when its new name is unset or empty, so an operator who already migrated is never overridden. Empty counts as unset because compose files render PV_X: ${PV_X:-}, and the daemon already reads an empty value as “not set”.
