- Added a DebugLogSource that reads dated log files and feeds the viewer from the debug selector.
- Made load-older handling asynchronous to fetch external chunks while preserving cursor and scroll state.
- Updated log viewer tests for the new options, external log sources, and async loading paths.
- Added pid filter toggle and load-older pagination controls to the debug log viewer.
- Introduced ctrl+o and enter shortcuts plus load-older row to page earlier logs while keeping the newest 50 visible.
- Adjusted cursor and selection to ignore non-log rows, allow select-all, and keep expansion anchored when rebuilding.
- Parsed pids from JSON log lines, read full log files for viewing, and covered pid filtering and pagination in tests.
- Extracted directory path utilities from multiple packages into a centralized '@oh-my-pi/pi-utils/dirs' module.
- Moved 30+ path helper functions (getAgentDir, getConfigRootDir, getPluginsDir, getMCPConfigPath, etc.) from scattered locations into a single shared utility module.
- Consolidated APP_NAME, CONFIG_DIR_NAME, and VERSION constants into the centralized dirs module for reuse across packages.
- Updated 70+ import statements across packages/ai, packages/coding-agent, packages/stats, and packages/tui to use the new centralized module.
- Removed local path construction logic and replaced with utility function calls for improved maintainability and consistency.
- Deleted packages/coding-agent/src/extensibility/plugins/paths.ts as its functions were moved to the centralized dirs module.
- Migrated all environment variable access from Node.js `process.env` to Bun runtime `Bun.env` API across the entire codebase.
- Updated 71 files including source code, tests, documentation, and configuration to use Bun's native environment variable API.
- Added comprehensive environment variables documentation in `packages/coding-agent/docs/environment-variables.md` covering 100+ environment variables organized by category.
- Updated CHANGELOG entries to reflect migration from `process.env` to `Bun.env` and environment variable prefix changes (PI_* vs OMP_*).
- Maintained identical behavior and logic across all changes - only the environment variable access method was updated.
- Exported getWorkProfile function and WorkProfile type from main package index for work profiling capabilities.
- Updated coding-agent debug module imports to use new main package exports instead of subpath imports.
- Added work scheduling profiler with always-on circular buffer sampling to track CPU scheduling patterns and task execution times.
- Added `getWorkProfile()` native function to retrieve profiling data including folded stacks, markdown summary, SVG flamegraph, and metrics for the last N seconds.
- Added work profile debug menu item to visualize CPU scheduling patterns via flamegraph in the coding agent.
- Added work profile support to report bundles with folded stacks, summary, and flamegraph visualization.
- Updated `launch_blocking()` and `launch_async()` functions to accept task name tags for profiling instrumentation.
- Added dependencies on inferno, smallvec, and heapless crates for profiling infrastructure.
- Added interactive `/debug` command with menu-driven interface for bug report triage and system diagnostics.
- Implemented CPU profiling workflow allowing users to capture performance profiles during issue reproduction.
- Added heap snapshot generation for memory issue analysis and debugging.
- Implemented debug report bundle creation with session data, logs, system info, and optional profiling artifacts.
- Added system information collection and display including OS, CPU, memory, and version details.
- Implemented artifact cache management with size statistics and cleanup functionality.
