v0.5.4

PiTTy v0.5.4

PiTTy v0.5.4 improves notification investigation, subagent visibility, and recovery from stalled context tools while preserving the fast terminal workflow.

Session-only notification history

• Every PiTTy toast, including RPC extension notify messages, is retained in an in-memory history for the current session.
• Full Markdown text remains available after a toast expires, including long command output and diagnostic output.
• History is intentionally session-only and bounded to 100 records; it is cleared when PiTTy restarts and is never written to disk.
• New notifications are unread. Opening a notification marks it read, and unread entries stay above read entries with newest-first ordering within each group.

Notification investigation UI

• A notification section appears below Todos in the right sidebar, with proportional space shared according to the Subagents > Todos > Notifications priority.
• Every visible panel keeps a header and content-row floor; notifications hide first when a short terminal cannot fit all panel floors.
• Notification lifecycle tones use semantic border colors, while read rows remain visually quieter.
• Clicking a notification opens a scrollable detail modal containing the complete text rendered as Markdown. Escape and the close control dismiss the modal without losing session history.

Subagent visibility and rendering

• The main chat now renders each logical subagent once. Later updates replace the existing entry instead of displaying duplicate copies.
• Foreground and asynchronous representations of the same subagent are merged, while distinct parallel child indexes remain separate.
• Completed subagent Markdown is finalized after its first rendered frame, preventing content above live responses from blinking or disappearing during long conversations.
• Viewport culling is disabled for the live main conversation and subagent inspector transcript, avoiding stale geometry while streaming content changes height.
• Subagent inspection supports OpenCode-style Ctrl+Down inspection, arrow-key navigation, Ctrl+Left/Right cycling, and Ctrl+Up return-to-chat aliases.

Context-tool and interrupt recovery

• Pi now forwards abort signals to the context-mode MCP bridge.
• Aborted or timed-out bridge requests send cancellation notifications, terminate the stuck child, and recover by respawning it for the next request.
• ctx_search has a bounded 50-second bridge recovery timeout; ctx_execute remains unbounded.
• Ctrl-C aborts active work with a single-flight guard. A subsequent Ctrl-C while that abort is still pending force-closes the renderer instead of leaving the terminal trapped behind a stalled request.

Regression coverage

• Added coverage for bounded notification retention and oldest-first eviction, unread/read ordering, panel allocation floors, clickable rows, and full Markdown detail rendering.
• Added coverage for one-owner subagent rendering, parallel-child identity preservation, Markdown finalization, subagent navigation, target-count hints, bridge recovery, and interrupt decisions.
