- OpenFromFile builds the new content in a separate PieceTable and
swaps it in only when complete. A reload that ran out of memory used
to leave the buffer empty (filename, journal and dirty state intact),
and the next save truncated the file.
- Editor::ProcessPendingOpens catches exceptions from opening (it runs
in every frontend's loop, outside command dispatch, so bad_alloc on a
huge file ended the editor); the terminal draw is guarded too.
- The hard-link save copy uses a unique mkstemp name, so a leftover
copy no longer blocks every later save; if no copy can be created the
file is still written in place.
- When no temp file can be created in the directory (file writable,
directory not), an existing regular file is written in place instead
of the save failing.

- kte refuses to start when stdin is not a terminal: piped bytes were
executed as editor commands (C-k s plus a path writes a file), and
after EOF the loop spun at full CPU with no way to quit.
- The terminal frontend handles all pending input before drawing (a
paste used to cost a frame and a full redraw per character) and
redraws only after input, a resize or deferred opens, else once a
second. The renderer caches, per row and buffer version, where the
horizontally scrolled part of a line starts and the cursor's render
column, instead of rescanning the line every frame. Idle CPU with the
cursor at the end of a 20 MB line: one full core -> ~1%.
- Buffers with a virtual name (+HELP+) are not journaled and saving one
asks for a file name; it used to write ./+HELP+ and journal under
that path.
- Yank with a repeat count is capped at 256 MiB in total instead of
reserving count x size bytes (C-u 1000000 C-y of a large kill).
- Remove an overload clang reports as unused (-Werror on macOS).

set_escdelay is an ncurses function, not a macro, so the #ifdef guard
compiled it out and ESC waited the 1 s default. KEY_RESIZE was mapped
to Refresh, the C-g cancel handler, which cleared the mark and
cancelled open prompts (including swap recovery) on every resize.
Audit findings B1, B2.

- Added detailed journaling system (`SwapManager`) for crash recovery, including edit recording and replay.
- Integrated recovery prompts for handling swap files during file open flows.
- Implemented swap file cleanup, checkpointing, and compaction mechanisms.
- Added extensive unit tests for swap-related behaviors such as recovery prompts, file pruning, and corruption handling.
- Updated CMake to include new test files.
- Created `piece-table-migration.md` outlining the steps to transition from GapBuffer to a unified PieceTable architecture.
- Included phased approach: extending PieceTable, Buffer adapter layer, command updates, and renderer changes.
- Detailed API changes, file updates, testing strategy, risk assessment, and timeline for each migration phase.
- Document serves as a reference for architecture goals and implementation details.
- Add visual file picker for GUI with toggle support.
- Introduce `GUIConfig` class for loading GUI settings from configuration file.
- Refactor window initialization to support dynamic sizing based on configuration.
- Add macOS-specific handling for fullscreen behavior.
- Improve header inclusion order and minor code cleanup.
