src/channel.rs had Channel / Notifier / MessageAdapter, each marked
#[expect(dead_code, reason = "稳定ID+阶段0占位…")]. All three had no
implementor, no caller and no dyn binding: Telegram outbound actually goes
through channel::telegram::TelegramClient::send_notification -> send_text,
held directly by worker.rs's MetadataWorker and notify.rs. The traits were
never on any path.
- delete the three traits + their #[async_trait] attributes
- drop the async_trait import from channel.rs (unused afterwards); the
dependency stays in Cargo.toml, still used by 5 other files
- drop the domain import from channel.rs (its only uses were inside the
deleted traits; the telegram module has its own Notification import)
- delete UserCommand from src/domain.rs -- its only consumer was Channel.
Notification stays (worker.rs:234 builds it)
- rewrite channel.rs's module doc: "only an adapter boundary in stage 0
(no bot commands yet)" was already false -- /help, /search, /summary
and /ai on|off are all parsed in worker.rs::parse_intent
The three dead-code attributes were the last three #[expect(dead_code)] in
src/. Two #[expect(clippy::too_many_arguments)] remain in notify.rs; those
are justified lint suppressions on router wiring, not placeholders.
External contracts unchanged: HTTP routes, Redis keys, error codes and the
error envelope are untouched.
GATE-P0: fmt / check / clippy -D warnings green, 61 passed / 0 failed / 1
ignored (unchanged).
