Problem: `get_doc` throws error with "attempt to get length of a userdata
value" when `item.documentation` is truthy but not a string (e.g. vim.NIL
from a JSON null).
Solution: Check `type(item.documentation)` before taking its length.

Problem: concatenating strings is slow
Solution: Use grow_string_tv() to grow the existing string buffer in
place when possible (Yasuhiro Matsumoto).

Problem: 'showcmd' buffer is being populated for :norm commands, which
can result in a recursive uv_run() when called from a msg_show
vim.ui_attach callback for a shell message.
Solution: The 'showcmd' buffer is never displayed while executing a
:normal command so prevent unnecessary work, avoiding the crash.
Problem:
clangd shows `Implicit conversion 'int' -> 'bool'` warnings.
This is mostly noise in this codebase.
Solution:
- Disable the warning.
- Get latest clang-tidy in CI.
Add a simple AGENTS.md rule for the AI-Assisted trailer in commit
messages and a workflow that adds the AI assisted label when PR commits

Problem: Statusline component of diagnostics allows only the default
format "sign:count".
Solution: Extend vim.diagnostic.Opts.Status to allow a custom signs
or formatting function that provides the status presentation.
Problem: The floating preview window (e.g. completion info)
has mouse=false, so scroll wheel events pass right through it.
Solution: Set mouse=true on the preview float so users can
scroll its content with the mouse wheel.
Problem: #38169 used compl_used_match to determine the CompleteDone
reason, but this fires too broadly, it also changes the reason to
"accept" when the popup was shown and the user dismissed it with <Esc>
or <Space>, breaking snippet completion with autocomplete.
Solution: Instead of checking compl_used_match in, check whether the pum
was never shown (compl_match_array == NULL) in ins_compl_stop().
When a match was inserted but the pum never displayed,
set the completed word so CompleteDone fires with reason "accept".
This keeps the "discard" reason intact when the user dismisses a visible
pum without confirming.
Problem: nvim_parse_cmd rejects valid commands like `:1` (range-only)
or `aboveleft` (modifier-only).
Solution: allow empty command when range or modifiers exist, and handle
execution using existing range command logic.
If the Nvim session has exited, the nvim_command will fail too.

Problem: blob: concatenation can be improved
Solution: Use ga_grow() to allocate space once and mch_memmove() to copy
the blob data as a single block and fall back to the previous
byte by byte append (Yasuhiro Matsumoto).

Problem: Mimicked block mode for cmdline entered while expanded
does not work intuitively for repeated commands yielding
messages exceeding the screen height. The expanded cmdline
resizes and scrolls to bottom/top when appending a message
and entering the cmdline. Also includes the entered command,
as opposed to the UI1 behavior.
Crash when scrolling to bottom of pager due to recursive
uv_run after shell message callback executes `nvim_command()`
with 'showcmd'.
Solution: Still mimic block mode when entering the expanded cmdline,
but when the entered command emits a message open the pager
with the current message content in the expanded cmdline.
Always route typed commands to the pager when it is open.
Use `nvim_buf_set_cursor()` instead of `nvim_command()`.
refactor(lua): add integer coercion helpers
Add vim._tointeger() and vim._ensure_integer(), including optional base
support, and switch integer-only tonumber()/assert call sites in the Lua
runtime to use them.
This also cleans up related integer parsing in LSP, health, loader, URI,
tohtml, and Treesitter code.

Problem:
In autocmd examples, using "args" as the event-object name is vague and
may be confused with a user-command.
Solution:
Use "ev" as the conventional event-object name.
Problem:
When `pum_above` is set, the info window uses `anchor=SW`. Updating the
info window height during `CompleteChanged` causes its top edge to shift,
so it no longer aligns with the top of the pum.
Solution:
Use `NW` as the anchor even when `pum_above` is true so the info window
remains aligned with `pum_row`.
Problem:
If NVIM_LOG_FILE, or the default fallback, is inaccessible (e.g.
directory is owned by root), users get confused.
Solution:
Show a warning when $NVIM_LOG_FILE or $XDG_STATE_HOME are inaccessible.
Also fix a latent memory leak: `os_mkdir_recurse` returns a uv error
code (int), but it was stored as `bool`, causing `os_strerror` to
receive an invalid error code and leak memory.

Problem: GUIFG, GUIBG, GUISP handling in do_highlight() is basically
the same code copy-pasted three times.
Solution: Pull the shared logic into a small set_gui_color() helper.
Problem: The GUIFG/GUIBG/GUISP handlers compare sg_rgb_{fg,bg,sp}
(RgbValue) against old_idx (color table index) instead of comparing
sg_rgb_{fg,bg,sp}_idx against old_idx, making did_change unreliable.
Solution: Use the _idx field for the index comparison and add the
missing sg_rgb_sp_idx assignment.
Problem: Reading large files is slow because UTF-8 validation and
newline scanning are performed byte-by-byte. Initial file
loading also triggers listener and channel processing.
Solution: Use memchr() for SIMD-optimized newline scanning, implement
word-at-a-time ASCII skipping during UTF-8 validation using a
bitmask, skip listener/netbeans/channel notifications
when the ML_APPEND_NEW flag is set during readfile()
(Yasuhiro Matsumoto).

Problem: Using a composing character as the end of a range inside a
collection may corrupt the NFA postfix stack
(Nathan Mills, after v9.1.0011)
Solution: When a character is used as the endpoint of a range, do not emit
its composing characters separately. Range handling only uses
the base codepoint.

Problem:
When stopping a PTY process on Windows, the exit code indicates that the
process is stopped by SIGTERM even when closing all streams is enough to
terminate the process. This is inconsistent with other platforms.
Solution:
Set exit_signal to SIGHUP instead of SIGTERM when using SIGHUP.
Problem:
Cross-compilation issues encountered when building Neovim for WASM.
When cross-compiling, three issues occur:
1. `-Wl,--no-undefined` — not supported by `wasm-ld`
2. `-lutil` — not available in the Emscripten sysroot
3. Doc generation fails because CMake tries to execute `$<TARGET_FILE:nvim_bin>` on the host machine, which fails because the binary is not native to the host. It fails with `/bin/sh: nvim.js: Permission denied`
Solution:
The fix includes skipping `-Wl,--no-undefined` and `-lutil` with `NOT CMAKE_CROSSCOMPILING` and adding `NVIM_HOST_PRG` variable to `runtime/CMakeLists.txt` so when cross-compiling, it uses a host native nvim binary for doc generation instead of using the cross-compiled target.
Problem:
In aec3d7915c Vim changed prompt-buffers
to respect 'modified' so the termdebug plugin can "control closing the
window". But for most use-cases (REPL, shell, AI "chat", …),
prompt-buffers are in practice always "modified", and no way to "save"
them, so *implicitly* setting 'modified' is noisy and annoying.
Solution:
Don't implicitly set 'modified' when a prompt-buffer is updated.
Plugins/users can still explicitly set 'modified', which will then
trigger the "E37: No write since last change" warning.
Problem: :terminal CWD restoration test may lead to an error log if
after_each() runs before the PTY process calls chdir().
Solution: Wait for some time before wiping the buffer, which can also
prevent SIGHUP being sent to the parent.
Problem: When reconfiguring a float reallocates the grid before the old
area is cleared, artifacts are left on the screen.
Solution: Use the last known compositor dimensions of a grid when
clearing the area covered by the old position.

No completionItem/resolve handler.
