Problem:
:checkhealth blocks as healthchecks perform slow work.
Solution:
Partially fix it: run Lua healthchecks in vim.async tasks and await
vim.health subprocesses. Existing synchronous checks still block
until they leverage the new apis.

Problem:
expand_msg() derives its start row from the pager buffer even when the
target is the cmd or dialog buffer, so the copied lines are appended
instead of replacing, and the copied extmarks are placed at pager rows in
a smaller buffer: "Invalid 'end_col': out of range", thrown inside a UI
event handler.
Solution:
Offset only when appending to a visible pager, and read the line count
after msg_clear(), whose autocmds may write to the pager. Copy marks with
`strict = false`, since the rows and columns are recomputed for a
different buffer and should clamp rather than raise.

Make gen_helptags.lua call help.lua instead of keeping its own tag
parser. Builds and :helptags now use the same code.
Allow the shared code to run without Neovim, and fail the build when tag

Only join paths for matches and entries needed for traversal. This
avoids string processing for rejected files and improves selective
searches across the Neovim tree by about 19-25%.

Problem: Generating helptags builds and queries a full vimdoc syntax
tree. This is much slower than the previous scanner and also happens
before discovering that the tags file cannot be written.
Solution: Extract tags with an LPeg grammar, reading each file once and
skipping example blocks and ordinary text. Open the output first so
unwritable directories can return immediately.
This restores legacy handling of tags inside inline code spans. On an
arm64 Mac, the 5.36 MB runtime corpus takes 24 ms instead of 604 ms,
with identical generated tags.

Problem: Autocmd callbacks currently have to rely on curwin, which may
already have changed by the time they run. This is especially noticeable
for WinNew, WinClosed, WinResized and WinScrolled.
Solution: Track the window in the autocmd context and expose it as ev.win.
Pass it explicitly for the window events that need it.

Problem:
When vim.lsp.rpc.connect is used for an LSP and the connection fails
(due to ECONNREFUSED, for example), the LSP client is left
uninitialized. Subsequent calls to vim.lsp.start will reuse the
uninitialized client, but no new connection will be attempted.
Solution:
When vim.lsp.rpc.connect encounters a connection error, terminate the
client. This allows the user to do something in response to the failed
connection in the on_exit callback, and also makes it so subsequent
attempts to start the LSP will try to establish a new connection rather
than using the previous uninitialized client.

Problem: Watcher failures are reported inconsistently, and callers
cannot detect when a watcher is no longer usable.
Solution: Route startup and event failures and unexpected inotifywait
exits through an optional on_error callback. Log to nvim-watch.log by
default. Ignore disappearing child directories and exits caused by
cancellation. Let LSP log failures and notify once per message, using
INFO for missing roots and ERROR otherwise, without interrupting
registration.

'cursorlineopt' (#41785)
Problem: CursorLineFold and CursorLineSign are only applied when
'cursorlineopt' contains "number" or is "both"
(Evgeni Chasnovski).

Problem:
The eol_offset used to decode multiline semantic tokens is computed as
vim.bo.fileformat[bufnr] == 'dos' and 2 or 1
which indexes the option value rather than the buffer, so it is never
"dos" and the offset is always 1. A token that crosses a line boundary
in a 'fileformat' of "dos" is then decoded one code unit short per line
ending, and the highlight extends past the end of the token.
Solution:
Read the option with the buffer-scoped form, vim.bo[bufnr].fileformat.
The existing multiline test covers both formats now. Its token length of
82 counts the line endings it spans, so the same token reaches four
characters less far once the buffer is "dos".

Problem:
vim.lsp.util.show_document() can fail to load the target buffer, most
visibly with E325 when another process owns the file's swapfile and the
user declines to open it. The Vim error escapes show_document() and
surfaces inside whichever LSP handler called it, instead of being
reported as a failure to show the document.
Solution:
Load the buffer up front with vim.fn.bufload(), before any of that
state is touched, and report the error instead of raising.

Problem: LuaLS struggles with the generics used in Nvim's runtime,
requiring broad diagnostic suppressions. Indexing is also slow.
Solution: Use EmmyLua for type checks in the build and CI. It offers
more sophisticated type checking, substantially better support for
generics, and much better flow analysis.
Correct the affected annotations. Use `@internal`, supported directly by
EmmyLua, instead of `@nodoc` for shared internal declarations, and
support it in the help parser.

Problem:
The LSP client excludes paths such as Git objects and installed
dependencies from file watching. However, watchdirs() still traverses
these subtrees before filtering which directories receive watchers,
paying the filesystem and Lua traversal cost for excluded content.
Solution:
Prune excluded subdirectories during the initial walk, and document
that excluding a directory also excludes its descendants.
Using the LSP client's existing **/node_modules/*/** exclusion on a
synthetic macOS tree with 100 installed packages and 4,000 files:
Before After
Directory scans 503 103
Entries inspected 4502 202
Directory watchers 103 103
The measurements use real filesystem calls and watcher handles, with
identical watcher paths for this exclusion.

Problem:
TSHighlighter._on_conceal_line() parses with the range { row, row }. A
Range2 has an exclusive end, so that is the empty range, and no injected
region ever intercepts it.
The root tree is parsed regardless, because its region is empty, so only
injections are affected: conceal_lines metadata coming from an injected
language's highlights query is dropped. on_range_impl() then records the
row in _conceal_checked, so the miss persists until the buffer changes.
For a markdown code block nested in a markdown code block, the inner
fence delimiters stay visible and nvim_win_text_height() reports 5 rows
where 3 are displayed.
Solution:
Pass the one-row range, as the on_range_impl() call below already does.

Problem:

'<MouseMove>', but at that point "typed" still holds raw key bytes. Thus
the comparison never holds and the branch its own comment describes

Solution:
Translate the key once, up front, so every comparison in the function
sees the same form.

Problem:
The #has-parent? predicate indexes the result of node:parent() without
checking it, so a capture that matches a tree's root node raises
query.lua:600: attempt to index a nil value
instead of simply not matching. In a highlights query that breaks
highlighting for the whole buffer. The sibling #has-ancestor? predicate
handles the same situation.
Solution:
Treat a missing parent as "does not match".

Problem: Nvim has many Lua APIs that start callback-driven work: timers,
jobs, libuv handles, and other event-loop tasks. Callers that need to
sequence or cancel that work have to build their own coroutine wrappers,
task bookkeeping, and cleanup rules. This makes async control flow hard
to share, test, and document.
Solution: Add `vim.async`, a structured-concurrency module vendored from
async.nvim. It provides task handles, await/pawait helpers,
sleep/timeout helpers, completion-order iteration, and semaphores on top
of Nvim's event loop.
The API follows the same broad model as Trio: async work has an owner,
tasks are awaited explicitly, and cancellation is cooperative. Include
generated vimdoc with an introductory overview and examples, a news
entry, and functional tests for the new module.

Problem: there should be exactly one cell of padding between sections,
and exactly one cell of minimum padding between the left and the right.
- Spaces between sections waste space when a section is empty.
According to a comment in #33036, this was the reason to avoid `%k`
and implement the keymap section with a vim expression, but other
sections still have this problem.
- The diagnostics section wastes space because it is not entirely empty
when there are diagnostics in another buffer.
- The terminal exit code section can touch the right side, e.g. the
ruler, even though it belongs to the left side.
Solution:
- Use auto-hiding item groups (`%(` without width fields) to get rid of
unneeded spaces when a section shows no information.
This simplifies the 'showcmd' and 'keymap' sections in particular.
- As a slight simplification, `term_exitcode` is moved into the flags
section since it is formatted with square brackets like a flag.
- Count the diagnostics for the current buffer specifically.
- Ensure at least one cell of padding between the left and the right
side by adding a space next to the separator `%=`.
Problem: some sections are implemented with `%{%`, even though
reevaluation of the expression result is not needed.
This leads to otherwise needless %-escaping in `progress_status`.
Solution: use `%{` instead.
Problem: `%{` and `%{%` (without items) replace spaces with fillchars.
This looks out-of-place inside the terminal exit code section, and in
contrast to all other sections, the 'busy' section is surrounded by
fillchars, which looks inconsistent, and with some terminal-font
combinations, ◐ overlaps the fillchar, e.g. Alacritty & JetBrains Mono.
Solution: use non-breaking spaces U+202F to avoid fillchar substitution.
Problem: sections that appear/disappear frequently can make otherwise
more stable sections jump around a lot.
Solution: sort the sections on the right roughly by volatility:
'showcmd' in first place, 'keymap' next to the ruler.

Problem:
`parse_ssh_config()` compares tables against a freshly allocated empty
table.
- In `parse_multiple_values()`, the guard which avoids flushing an empty
accumulator never applies. Runs of separators and trailing whitespace
push empty strings into the results, and `is_valid()` does not filter
them. `Host alpha beta ` parses as `{ 'alpha', '', 'beta' }`.
- In `parse_value()`, the condition reduces to `chr == '"' and quoted`.
`quoted` starts false and only that branch sets it, so it can never
become true: quotes are never recognised and are inserted literally,
and the unterminated-quote check is unreachable.
Solution:
Compare `#val` instead. Add a test for repeated and trailing separators.

iteration directions. Add tests using a predicate which dereferences its
argument and matches every element, forward and reversed.

Problem:
Fallback pynvim version lookup is broken since Vimscript-to-Lua rewrite.
- `vim.fs.basename()` returns the module filename instead of the
directory needed to discover adjacent metadata. This produces an
empty metadata list, hiding the remaining issues.
- `table.sort()` requires a Boolean comparator, while
`vim.version.cmp()` returns a number.
- `table.sort()` sorts in place and returns no value, so assigning its
result discards the metadata list.
Solution:
- Use `vim.fs.dirname()` to discover adjacent package metadata.
- Use `vim.version.gt()` as the descending Boolean comparator.
- Sort the metadata list in place.
This restores fallback version detection when `neovim.VERSION` is
unavailable.
