- Companion `node.*` registration is per WebSocket connection; reconnects must re-register capabilities before invoking node RPC methods (or use runtime-client reconnect state replay to re-register/status/location/push automatically).
|

- Companion packaging/bootstrap can be generated offline via `flynn companion --export-bootstrap <path|->`, which emits resolved gateway/node/runtime settings without opening a WebSocket session.
|
||||
- Companion release artifacts can be generated via `flynn companion --export-release-bundle <dir>`, producing bootstrap JSON + launcher + README + `CHECKSUMS.sha256` for installable shell distribution workflows.
|
||||
- Generated launchers validate `CHECKSUMS.sha256` before invoking `flynn companion`, reducing accidental tampered-bundle launches.
|
||||
- Companion release-bundle exports can optionally be signed (`--signing-key`, `--signing-key-id`) to emit `CHECKSUMS.sha256.sig` for distribution trust verification.
|
||||
- Companion release bundles can be verified before install via `flynn companion --verify-release-bundle <dir>` with optional signature-key checks.
|
||||
- Companion platform starter scaffolds can be generated via `flynn companion --export-shell-template <dir>` for macOS/iOS/Android reference app bootstrapping.
