Minor Changes

• 26b4489: SEP Phase 4 (engine) — commands, session actions, and hot reload.

  ExtensionHost gains the command surface and the command-tier deadlock guard:

  • Command dispatch — run_command(ext, command, arguments) sends
    command/execute to the owning extension with a COMMAND-tier context;
    complete_command(...) round-trips command/complete for argument
    autocomplete (best-effort — an extension without a completer yields no
    suggestions, never an error). commands() and shortcuts() surface the
    registered slash-commands and keyboard shortcuts for a frontend's palette.
  • Session actions — HostDelegate grows session_send_message,
    session_send_user_message (deliver_as steer/follow_up/next_turn), and
    session_append_entry. The headless engine has no session, so the defaults
    report -32004 CapabilityDisabled; frontends with a session store override
    them. Every session action is gated by validate_command_context: it must
    present a COMMAND-tier context whose epoch is still current, else
    -32003 ContextViolation — fired in HostInbound BEFORE the delegate runs.
  • Hot reload — reload(name) notifies the extension (session_shutdown
    reason reload), bumps the shared epoch so every context token it still holds
    is invalidated, respawns the subprocess (the generation guard discards late
    replies from the dead child), re-runs initialize, and notifies it again
    (session_start reason reload). The manifest's declared-events clamp is
    re-applied so a restart can never widen a project extension's subscriptions.

  New protocol types (CommandExecuteParams/Result, CommandCompleteParams/Result,
  Completion, ShortcutRegistration, DeliverAs, Session*Params), an
  InitializeParams.flags map for delivering parsed CLI flag values, and a
  Registrations.shortcuts list. The reference sep-echo-peer registers a command

  • shortcut and answers command/execute/command/complete. Purely additive:
    with no extension host attached the agent loop is unchanged.
