- Wrapped selector and overlay list windows in ScrollView for proportional right-edge scrollbars.
- Dropped numeric position/count footers in favor of the scrollbar.
- Simplified SelectList status line to search hints only.
- Added ED3-risk autocomplete repaint test for POSIX terminals.
- Added helpers to synthesize RawSseEvent records for inbound, outbound, and malformed Codex WebSocket traffic.
- Passed onSseEvent through websocket transport and stream setup so frames are forwarded to the raw-SSE debug pipeline during streaming.
- Added a stream test that verifies outbound and inbound websocket frames are emitted with SSE-style raw lines for the debug viewer.
Adds an opt-in onSseEvent callback across HTTP-streaming providers (Anthropic, OpenAI Responses/Completions, Azure OpenAI Responses, OpenAI Codex SSE, Google Gemini CLI, GitLab Duo, Kimi, Synthetic) so callers can inspect raw SSE frames without altering parsed output. Provider fetch wrapping only tees response bodies when an observer is wired; standalone packages/ai consumers without onSseEvent are not penalized.
Adds streamIdleTimeoutMs (env: PI_STREAM_IDLE_TIMEOUT_MS, with PI_OPENAI_STREAM_IDLE_TIMEOUT_MS as a backward-compatible alias). Anthropic now enforces a steady-state idle watchdog (default 120s) in addition to the first-event watchdog. OpenAI Responses, Azure Responses, and Codex (SSE + WebSocket) gain a semantic-progress predicate so response.in_progress-style keepalives no longer keep stalled tool calls alive forever.
Adds a coding-agent debug-panel raw SSE viewer backed by a per-session bounded buffer (1000 records / 512KB) that AgentSession populates unconditionally so users can post-hoc inspect a stuck stream from the TUI.
