+## Outbox file delivery
+
+Agents write files to `.untether-outbox/` during a run. On completion, `outbox_delivery.py` scans, validates (deny-glob, size limit, file count cap), sends as Telegram documents with `📎` captions, and cleans up. Configure via `[transports.telegram.files]`: `outbox_enabled`, `outbox_dir`, `outbox_max_files`, `outbox_cleanup`.
+
+## Progress persistence
+
+`progress_persistence.py` tracks active progress messages in `active_progress.json`. On startup, orphan messages from a prior instance are edited to "⚠️ interrupted by restart" with keyboard removed.
+
+## Telegram update_id persistence (#287)
+
+`offset_persistence.py` persists the last confirmed Telegram `update_id` to `last_update_id.json` (sibling to config). On startup, `poll_updates` loads the saved offset and passes `offset=saved+1` to `getUpdates` so restarts don't drop or re-process updates within Telegram's 24h retention window. Writes are debounced (5s interval, 100-update cap) via `DebouncedOffsetWriter` — see its docstring for the crash/replay tradeoff. Flush happens automatically in the `poll_updates` finally block.
+
+## TelegramBridgeConfig hot-reload (#286)
+
+`TelegramBridgeConfig` is unfrozen (slots preserved) as of rc4. `update_from(settings)` applies a reloaded `TelegramTransportSettings` to the live config; `handle_reload()` in `loop.py` calls it and refreshes the two cached copies in `TelegramLoopState`. `route_update()` reads `cfg.allowed_user_ids` live so allowlist changes take effect on the next message. Restart-only keys (`bot_token`, `chat_id`, `session_mode`, `topics`, `message_overflow`) still warn with `restart_required=true`.
+
+## sd_notify (#287)
+
+`untether.sdnotify.notify(message)` sends `READY=1`/`STOPPING=1` to systemd's notify socket (stdlib only — no dependency). `NOTIFY_SOCKET` absent → no-op False. `poll_updates` sends `READY=1` after `_send_startup` succeeds; `_drain_and_exit` sends `STOPPING=1` at drain start. Requires `Type=notify` + `NotifyAccess=main` in the systemd unit (see `contrib/untether.service`).
+
+## /at command (#288)
+
+`telegram/at_scheduler.py` is a module-level holder for the task group + `run_job` closure; `install()` is called from `run_main_loop` once both are available. `AtCommand.handle` calls `schedule_delayed_run(chat_id, thread_id, delay_s, prompt)` which starts an anyio task that sleeps then dispatches. Pending delays tracked in `_PENDING`; `/cancel` drops them via `cancel_pending_for_chat(chat_id)`. Drain integration via `at_scheduler.active_count()`. No persistence — restart cancels all pending delays (documented in issue body).
+
+## Plan outline rendering
+
+Plan outlines render as formatted Telegram text via `render_markdown()` + `split_markdown_body()`. Approval buttons (✅/❌/📋) appear on the last outline message. Outline and notification messages are cleaned up on approve/deny via `_OUTLINE_REGISTRY`.
+
+## /new command
+
+`/new` cancels all running tasks for the chat via `_cancel_chat_tasks()` (in `commands/topics.py`) before clearing stored sessions. This prevents process leaks from orphaned Claude/engine subprocesses.
