"""T16 (#134889): classic-CLI ``/status`` names a gateway session by its canonical ``local-…`` id.

Main printed the ``YYYYMMDD_HHMMSS_<hex>`` id it minted itself. Under the one gateway the
session row's only id is the canonical ``local-`` + sha256 receipt identity (``local_identity``);
no legacy alias exists to print. ``/status`` shows that full id because it is the value every
other surface uses for the same session: the exit epilogue's ``hermes --resume <id>``, the TUI
and gateway ``/status``, ``hermes sessions list`` and ``state.db``. A shortened or reformatted
id would be one more spelling that a user copies and the resolver may not accept.
