- Extracted tab width resolution from pi-natives to pi-utils with EditorConfig caching support.
- Made tabWidth parameter required in native text functions (visibleWidth, truncateToWidth, wrapTextWithAnsi, sliceWithWidth, extractSegments).
- Removed process-wide tab width state management from pi-natives text module.
- Consolidated wrapper node promotion logic in chunk classification with abbreviated string representations.
- Removed path-clean and pathdiff dependencies from pi-natives.
- Updated all consuming packages to import tab width functions from pi-utils and pass explicit tabWidth parameters.
- Migrated native bindings from TypeScript wrappers to NAPI-RS generated modules with auto-generated type definitions and runtime enums.
- Replaced chunk tree API with stateful ChunkState class supporting render, edit, and resolve operations with improved error handling.
- Converted callback signatures to error-first pattern (error, result) for shell, PTY, glob, and grep operations.
- Introduced type-safe enums for MacOSAppearance, GrepOutputMode, KeyEventType, ImageFormat, and AstMatchStrictness replacing string literals.
- Refactored chunk tree implementation with dedicated modules for edit, indent, resolve, and state management with comprehensive validation.
- Moved clipboard utilities from native bindings to coding-agent package with improved OSC 52 and Termux compatibility.
- Extracted screenshot formatting logic into dedicated `formatScreenshot()` function with options support.
- Consolidated prompt source deduplication into `dedupePromptSource()` helper to prevent rule duplication.
- Refactored editor text sanitization to use `replaceTabs()` utility for consistent tab width handling.
- Added test coverage verifying editor respects configured tab width when loading text programmatically.
- Rewrite stop() to use viewport-relative cursor positioning instead of
content-length, preventing blank gaps when content is shorter than viewport
- Replace trailing \r\n\x1b[2K clear loops in repaintViewport() and
height-increase path with \r\n\x1b[J to avoid cursor drift past content
- Add 12 TUI regression tests for exit gaps, content shrink, and overlay
dismiss cursor recovery
- Add 6 coding-agent controller tests for /new and /tree commands
Replace destructive \x1b[3J\x1b[2J\x1b[H full-redraw sequence with
scrollback-preserving repaint helpers:
- seedTranscript: first paint with no prior frame, writes full transcript
without clearing scrollback
- repaintViewport: trusted-frame repaints that scroll viewport-shift
delta into scrollback before overwriting visible rows in-place
- Height-increase handler that pushes revealed scrollback back before
reclaiming the display
Replace requestRender(true) state destruction with a one-shot
without resetting #previousLines or cursor bookkeeping.
Track #previousHeight to detect terminal height increases that pull
scrollback lines into the visible area.
fixes#507

- Added ctrl+_ to the default undo binding list to preserve legacy shortcuts.
- Extended editor tests with keybinding helpers to cover custom undo bindings.
- Reorganized settings tabs from 12 to 8 focused categories (appearance, model, interaction, context, editing, tools, tasks, providers) with consolidated status line settings.
- Added 15+ new settings for status line customization, sampling parameters, speech-to-text, web search, and edit mode configuration.
- Changed default agent model from `default` to `pi/task` for independent subtask configuration and updated model resolution to support single-pattern inheritance fallback.
- Updated system prompt to use ISO 8601 date format (YYYY-MM-DD) and renamed 25+ UI labels for consistency across settings interface.
- Updated tab icon symbols across unicode, nerd, and ASCII presets to reflect new tab organization.
- Simplified settings definitions and removed unused imports to reduce code complexity.

- Fixed OSC 11 background color detection to handle partial escape sequences that arrive mid-buffer, preventing user input from being swallowed.
- Fixed race condition where overlapping OSC 11 queries would be incorrectly cancelled by DA1 sentinels from previous queries by implementing a query queueing mechanism.
- Refactored OSC 11 query handling to use queuing instead of immediate restart, improving robustness of terminal appearance detection.
- Added comprehensive test coverage for terminal appearance detection including partial buffer handling, query queueing, and debouncing behavior.
- Added test cases for theme auto-detection to verify terminal-reported appearance takes precedence over environment variables and platform-specific detection.
- Added checks to filter out Kitty release events (event_type 3) in both matches_key_inner and parse_key_inner functions. Added comprehensive tests for both key matching and input handling to verify release events are ignored while press and repeat events are still processed correctly.

- Added test case verifying strikethrough resets at line wraps while preserving foreground and background colors.
- Added TypeScript test case for strikethrough styling behavior across wrapped lines.

Refactor TUI rendering into explicit hard-reset and viewport-repaint paths with safer differential fallbacks for offscreen/overflow cases.

Synchronize cursor dedup cache across all render write paths to avoid stale #lastCursorSequence behavior after full redraws.
Remove PI_TUI_RESIZE_CLEAR_STRATEGY and lock resize behavior to deterministic semantics (width hard reset, height viewport repaint).
Expand terminal regression coverage with new render-regressions tests and substantial overlay/scroll stress scenarios to guard scrollback growth, anchoring drift, and no-op churn.
- Introduce `deferrable?: boolean` on AgentTool, CustomTool, and ToolDefinition.
AstEditTool sets it to true; resolve is now injected only when at least one
active tool is deferrable (previously unconditional).
- Replace single-slot PendingActionStore (set/get/clear) with a LIFO stack
(push/peek/pop/clear). Multiple deferrable tools can stage independent
preview actions; resolve always consumes the topmost one first.
- Wire pendingActionStore through discoverAndLoadCustomTools / loadCustomTools /
CustomToolLoader so custom tools can call pushPendingAction(action) to
register a resolve-compatible pending action with label, apply callback,
optional details, and optional sourceToolName.
- Export HIDDEN_TOOLS and ResolveTool from the SDK for manual tool composition.
- Add CustomToolPendingAction type and pushPendingAction to CustomToolAPI.
- Update createAgentSession to re-inject or remove resolve after the deferrable
audit, consistent with createTools behavior.
- Add LIFO resolve test, update existing tests (set -> push, get -> peek).
- Add docs/resolve-tool-runtime.md covering PendingActionStore internals,
built-in producer example, and custom tool usage guide.
- Added `PI_TUI_RESIZE_CLEAR_STRATEGY` environment variable to control terminal resize behavior: `viewport` (default) renders only visible content to minimize scrollback pollution, or `scrollback` clears all history.
- Changed resize redraw logic to support viewport-only rendering strategy, reducing scrollback accumulation during terminal resizing.
- Added 2 integration tests to verify viewport and scrollback resize strategies work correctly.
- Fixed loader component text overflow by truncating lines exceeding terminal width using column-aware slicing.
- Improved terminal clear logic on resize to use hard clear (\x1b[2J) preventing stale wrapped cells.
- Added test coverage for loader component line clamping to verify rendered lines fit within terminal width.
- Refactored terminal clear conditional logic from ternary to multi-line if-else for improved maintainability.
