 - **Proxy runtime**: The per-user background host process, independent of the GUI's lifetime, that runs the external tunnel service and loads the optional generated ACL sidecar.
 - **Legacy configuration**: The server list and preferences persisted by the frozen implementation in `Legacy/`.
 - **Legacy import**: The user-confirmed, read-only translation of a Legacy configuration's server records into a separate manual group in 2.0. It migrates no preferences, activates no target, and neither starts proxying nor alters the Legacy source.

+- **Runtime configuration file**: The derived JSON document used by the external tunnel service for the active target. It carries only connection-effective values (endpoints, credentials, encryption, plugin, listeners, ACL); user-visible display names are catalog metadata and never enter the file. Fields NG2 omits are left to the bundled `sslocal` defaults; the file is not the user-managed server configuration or subscription document.
 - **Sensitive information**: Server passwords, plugin options (sensitive in their entirety), and nonempty user-provided remote URLs, including subscription URLs.
 - **Credential exposure boundary**: This product reduces accidental disclosure and exposure to other user accounts, but does not guarantee protection against a compromised same-user process, root access, or APFS snapshots and backups; it does not promise secure erasure.
 - **Credential reference**: A non-secret association from a server configuration, subscription, or remote-URL setting to its durable credential; the credential value is kept outside the configuration tree and resolved only when needed.

 - Activating a server selects that one server. Activating a group recursively expands activation-candidate server leaves in explicit child order and passes them to the external proxy service; invalid leaves are omitted and surfaced, while a group with no activation candidate rejects activation atomically.
 - The active target remains the selected node ID and is not silently replaced by a descendant chosen by `sslocal`. If it is deleted, has no activation candidate, or is otherwise invalid, the target is cleared and proxying stops rather than falling back silently.
 - After a committed edit to the active target's subtree, the target is re-expanded immediately: a non-empty set of activation candidates updates the runtime atomically; no activation candidate clears the target and stops proxying without fallback.
+- A committed catalog edit that leaves the runtime configuration file's bytes unchanged — including edits outside the active target's subtree, remark-only changes, and no-op re-saves — triggers no runtime convergence work: no contract write, no reload signal, no restart of the external tunnel service, and no launch health re-probe. Catalog revalidation (activation-candidate skips, target invalidation) still happens on every commit. Within an active group subtree, a connection-value change — including member order — does change the runtime file and converges.
 - Manual nodes may move between the catalog root and manual groups, carrying their subtree and child order without changing identity or ownership; cross-source moves, shared parents, and cycles are rejected.
 - Manual catalog ownership is independent of proxy mode: removing the manual proxy mode does not remove manual groups, manual servers, or records imported into a manual group.
 - Empty groups may persist and remain editable, but cannot be activated. Deleting a server configuration or an empty manual group takes one user confirmation. Deleting a non-empty manual group recursively deletes its descendants and takes a second confirmation that names the subtree scale and that the subtree's server credentials are removed.
