v0.16.1

ductor v0.16.1

Patch release for Telegram streaming, heartbeat/session locking, and uv-based self-upgrades.

TL;DR

• Telegram final answers are reliable again — reasoning-only or tool-heavy streaming turns no longer suppress the final answer.
• Heartbeat no longer leaves chats stuck busy — heartbeat turns now serialize through the shared session lock, and post-stream memory maintenance no longer re-enters the active Telegram lock.
• uv tool install ductor can self-upgrade — /upgrade now detects uv tool installs and runs uv-native upgrade commands instead of python -m pip.
• Telegram reasoning/tool visibility controls — merged PR #111 by @takaok5 for separate reasoning stream, tool progress, and thinking-indicator controls.
• Packaged example config is valid JSON — removed trailing commas and excluded the example JSON from Ruff auto-formatting.

Fixes

Telegram reasoning stream UX (#111)

Merged contributor PR #111 by @takaok5.

• Reasoning/thinking deltas now have their own callback path.
• Telegram can show reasoning separately from the lightweight thinking indicator.
• Tool-progress visibility and thinking-indicator visibility are configurable.
• If only reasoning/tool activity streamed during a turn, ductor still sends the final answer.
• Invalid explicit Codex reasoning-effort overrides now fail visibly instead of being silently dropped.

Heartbeat chat lock recovery (#115)

Heartbeat execution now uses the shared per-session LockPool, so it cannot race normal Telegram ingress on the same chat/topic.

The related memory-maintenance path was also adjusted: streaming turns schedule post-turn memory flush/compaction in the background, behind the same lock, instead of awaiting it while Telegram still holds the lock. This avoids the self-deadlock pattern where no provider process is running, the queue is empty, but the chat still appears permanently busy.

uv self-upgrade support (#112)

Install detection now recognizes uv tool environments from sys.prefix / sys.executable, and the updater builds uv-native commands:

uv tool upgrade ductor
uv tool upgrade --reinstall ductor==0.16.1

This fixes /upgrade for users installed with:

uv tool install ductor
