/pairing is now a first-class built-in command dispatched through
CommandRouter, just like /status, /model, /dream, etc.
Benefits:
- WebUI automatically shows /pairing in the slash command palette
(because builtin_command_palette() feeds /api/commands).
- All channels (Telegram, Discord, WebSocket, etc.) use the same
dispatch path for /pairing; no more channel-level interception.
- The command still only works for already-authorised users because
is_allowed() gates message ingestion before the bus.
Changes:
- Add handle_pairing_command() to nanobot.pairing.store — pure
function callable from CLI, CommandRouter, and tests.
- Add cmd_pairing to nanobot.command.builtin and register in
BUILTIN_COMMAND_SPECS + register_builtin_commands().
- Remove BaseChannel._handle_pairing_command() and the /pairing
interception logic from _handle_message().
- Clean up unused pairing imports from base.py.
- Add unit tests for handle_pairing_command and cmd_pairing dispatch.
Non-priority slash commands (e.g. /new, /help, /dream-log) arriving
while a session has an active LLM turn were silently queued into the
pending injection buffer and later injected as raw user messages into
the LLM conversation. This caused the model to respond to "/new" as
plain text instead of executing the command.
Root cause: the run() loop only checked priority commands (/stop,
/restart, /status) before routing messages to the pending queue. All
other command tiers (exact, prefix) bypassed command dispatch entirely.
Changes:
- Add CommandRouter.is_dispatchable_command() to match exact/prefix
tiers, mirroring the existing is_priority() pattern.
- In run(), intercept dispatchable commands before pending queue
insertion and dispatch them directly via _dispatch_command_inline().
- Extract _cancel_active_tasks() from cmd_stop for reuse; cmd_new now
cancels active tasks before clearing the session to prevent shared
mutable state corruption from concurrent asyncio coroutines.
- Update /new semantics: stops active task first, then clears session.
- Update documentation in help text, docs, and Discord command list.
