l0ng-ai 87f8200207 fix(ssh): offer keys in the order the user asked for them
Every public key offered spends one of the server's `MaxAuthTries` — six
by default — whether or not the server wants it, so the order decides who
gets locked out when the budget runs dry. Offering the `~/.ssh` defaults
before the agent, and offering them on top of a profile's own key rather
than instead of it, spent the budget on the keys least likely to be
accepted: three stale defaults in `~/.ssh` with the working key in a
loaded agent could exhaust the attempts before the agent was reached, and
a profile naming its own key came off worse than one naming none.

Order the sources by how plainly the user asked for the key:

  1. a key the profile names   — "use this one"
  2. the agent                 — "I loaded these"
  3. the ~/.ssh defaults       — nobody said anything, we are guessing

Steps 1 and 3 are the same leg, because the defaults now stand in for the
identity list only when the profile names no key of its own, the way
`IdentityFile`'s default works in ssh_config — verified against the local
OpenSSH: `ssh -G` lists five defaults with no IdentityFile and only the
named key with one. WezTerm and Tabby both replace rather than append too
(wezterm-ssh/src/config.rs:589, tabby-ssh/src/session/ssh.ts:194).

The file-vs-agent order has no single convention to follow — WezTerm asks
the agent first, Tabby reads files first, OpenSSH merges the two and
trims the agent's extras with `IdentitiesOnly`, which tty7 does not parse.
This order agrees with OpenSSH and Tabby when the user named a key and
with WezTerm when they did not.

Dedup by canonical path goes with it: the two lists are alternatives now,
so there is nothing to dedup between them. `auth_steps` and
`identity_offers` carry the two rules as pure functions, so both are unit
tested instead of living inside the async round. The GUI's keychain
preload follows the same rule, so both sides still key passphrases by the
same strings.

Closes #513.

Hongwei Qin 364e24af87 feat(ssh): probe ~/.ssh default identity keys (#507)
A connection with no explicit IdentityFile used to offer the server
nothing at all when the agent was unavailable — the default on Windows,
where the OpenSSH Authentication Agent service ships disabled — and then
reported "no public key was accepted", for keys it had never sent.

Offer the `~/.ssh` defaults (id_ed25519, id_ecdsa, id_rsa) after the
explicit identities and before the agent, from one shared candidate list
in `core::ssh_profile` so the GUI and the daemon key `key_passphrases`
by the same strings. Candidates are deduped against the explicit list by
canonical path, comparing the expanded paths the reader actually opens.
A discovered key that is encrypted is used only when its passphrase is
already cached, never prompted for; explicit keys keep prompting. Files
that do not exist are skipped in silence, a `.pub` is never offered as a
private key, and the failure text now separates "the server turned these
down" from "nothing usable was found".

The tests build their ed25519 fixture at run time from a fixed seed
rather than embedding a PEM blob, so the tree carries no private key.

Closes #484.

l0ng-ai 00e1aa8218 docs: correct claims that no longer match the code
Audited every page under docs/ against the source. Fixes for what the
code actually does:

- agents: the status vocabulary is idle/working/waiting/done, not
  running/waiting/idle; hook rows grow a separate Uninstall button; the
  Settings table labels read "Copilot CLI" and "Grok Build"; Copy Session
  ID lives in the tab's context menu, not the pane's
- cli: `pane ls --all` reports the owning workspace id, not "tty7-cli";
  document bare `tty7 [PATH]` as the GUI launcher it is instead of listing
  it as unimplemented; note `active_tab` and the `diagnostics` array; wait
  also defaults to $TTY7_PANE
- git: the branch dropdown is a plain list with no search box and no
  stash-and-switch, and checkout is not a palette command; quote the diff
  overlay's own overflow notice rather than the sidebar's
- window: the unread marker tracks a finished agent turn, not any output;
  rows cannot be dragged across groups; the sidebar and `tty7 tab ls`
  resolve labels differently; drop Toggle Commit History and Checkout to
  from the palette's Git group; ~/.ssh/config aliases are not palette
  entries
- terminal: Ctrl+R dedups by command text and shows no directory; Esc does
  not dismiss a ghost suggestion; document Cmd+Enter
- remote: GSSAPI is an ordinary Auth choice, not a managed-connection-only
  mechanism
- fonts: Maple Mono NF CN leads the chain on Windows and Linux only; list
  the real per-platform defaults
- settings paths: the three Links settings and per-pane history were filed
  under the wrong sections

l0ng-aiandl0ng-ai 72060d8257 fix(ui): stop washing out the workspace discs in the switcher (#483)
The monogram disc beside every workspace row was drawn at opacity 0.55
unless that row was the current workspace, and the initial inside it is
already the foreground at 0.65 — so the letter landed at about 0.36 and
went illegible on exactly the rows the panel exists to let you pick
between. Only one row in the list is ever the current workspace; the
other however-many all got the dimmed treatment.

The liveness dot is painted on the wrapper rather than inside the disc,
so it never dimmed with it: a washed-out grey blob with a full-strength
green dot stuck to its corner, which is what made the column look dirty
rather than quiet.

Drop the dimming. Nothing is lost by it — the current workspace already
carries a "this window" badge, a medium-weight name and the selected
background, so the disc was saying a fourth time what three louder
things had said. `current` was the only reason the helper took that
argument, so it goes too.

l0ng-aiandl0ng-ai c4645aeea8 feat(terminal): draw a scrollback scrollbar down the right edge of a pane (#480)
A pane's scroll position lives in alacritty's `display_offset` — rows of
scrollback, not pixels of laid-out content — so it has no `ScrollHandle`
to hand a scrollbar. `TerminalScrollHandle` implements gpui-component's
`ScrollbarHandle` over the grid instead, which lets the pane draw the
same `Scrollbar` the sidebar and every list already use: same theme,
same `Scrolling` show mode, same fade-out.

The bar never touches the terminal. `set_offset` only records the row it
wants; `sync_scrollbar` applies that on the next render — clearing the
sub-line remainder and cancelling an in-flight smooth scroll on the way —
and reports back where the grid actually ended up.

Scrollback piling up at the live edge is deliberately not reported: the
bar shows itself whenever the offset it reads changed, so a pane printing
a build log would otherwise hold a thumb on screen for as long as the
output ran. Every other change passes through, including the history
shrinking, which is a cleared scrollback rather than growth.

Closes #432

l0ng-ai 9735a490b5 Merge pull request #479 from l0ng-ai/perf/wsl-tab-open-cost
perf(wsl): stop re-proving the distro on every new tab

l0ng-ai d09fc10878 fix(wsl): make the remembered server path safe to trust
The note the last commit introduced had no working way to be wrong. Its only
repair was the router forgetting the distro when `RemoteLink::wsl` returned an
error, and that call only spawns `wsl.exe` — which starts perfectly happily
with a server path that no longer exists inside the distro. The exec failure
arrives later, as an EOF on the bridge, so a distro that was reinstalled or had
its bin directory cleaned out failed every WSL tab from then on, with nothing
re-installing it and no way out but restarting tty7.

So forget it where the truth actually shows up: a bridge that closed without
ever sending a byte never ran, and after one of those the next pane proves the
distro again. The spawn-error retry stays, but only when the path came from
memory — a path proved a moment ago will prove the same, and re-probing it just
doubles the wait before the error reaches the user.

Two more things the note quietly took away.

It was read before `install_lock`, so a pane spawn was no longer mutually
exclusive with `replace_wsl_server`, whose whole job is to move the file the
note names: a window restoring panes while the user updates the WSL server
could spawn the binary being replaced. The read moves under the lock, which
costs nothing when no install is running and correctly waits when one is.

And it short-circuited `Installer::run`, the only thing that notices a foreign
build serving the distro — so the "a different build of tty7-server is serving
this machine" warning reached the first pane of the daemon's lifetime and no
other, including a whole new GUI session, since the daemon outlives one. The
note now carries the mismatch it found and re-files it for each later pane,
which is the same warning without the five round trips that found it.

The wall-clock budget in the remembered-answer test is gone: the returned path
already proves no probe ran, and 200ms of elapsed time on a loaded CI box only
ever proved the box was loaded.

l0ng-ai e0745329db fix(wsl): do not pass off a half-read registry as the distro list
`registry_user_subkeys` ended its walk on any non-zero return and reported
what it had as the answer. Only one of those returns means "that was all of
them"; the rest mean the walk stopped early — a `wsl --unregister` running
right now, a Store install rewriting `Lxss` underneath it — and a failure at
the very first index came back as `Some(vec![])`, an authoritative "there are
no distros". The sweep that feeds the shell menu keeps the last good list only
when the probe says `None`, so that empty answer erased the user's distros for
the length of the TTL, with no error anywhere and no `wsl -l -q` to catch it:
the fallback only runs when the key will not open at all. The walk now says
nothing unless it reached the end.

`State` is now read too, the way Windows Terminal reads it. A `DistributionName`
is not a promise that the distro can be entered: an install that was cancelled
half way, a failed `--import`, one being uninstalled as we look, all leave the
key behind. `wsl -l -q`, which this replaced, never listed those; without the
filter they arrive in the shell menu and open a pane that dies of a WSL
registration error. A key with no `State` at all is still taken at its word,
which is the conservative direction — inventing one would hide working distros,
which is the mistake `Modern = 1` would have been.

That also makes `registry_user_dword` production code rather than a `cfg(test)`
copy of `registry_user_string`'s FFI scaffolding kept alive for one assertion.

The timing test now skips when the registry has nothing to read: on a machine
with no `Lxss` key the listing is *supposed* to go to `wsl.exe` and wait, so
timing it there failed the test on exactly the machines the fallback is for.
And hoisting `LXSS` had left `default_wsl_distro`'s doc comment attached to the
const; it goes back on the function.

l0ng-ai 49bfe59410 docs: drop the orchestration skill tty7 no longer installs
The in-app switch that wrote `~/.claude/skills/tty7-orchestration` was
removed in da6df70, before any release carried it — `git grep` finds it in
no tag. The changelog entry recording it landed the same day, written from
the branch's state rather than the tree's, and the documentation site (#478)
was then written from the changelog, so the feature reappeared on three
pages describing something the app has never shipped.

The orchestration page now says what is true: nothing is installed for you,
the agent-facing contract is `skills/tty7` and you add it yourself with
`npx skills add l0ng-ai/tty7`. That skill covers driving panes; `wait` is
documented on the orchestration page itself, so neither page promises what
the other holds.

l0ng-ai 7f16f6a6ff fix(wsl): read the distro list from the registry, not the WSL service
`wsl -l -q` has to reach the WSL service, and reaching the WSL service is
the part that can be slow. Behind a hardcoded 3s timeout that made the
listing all-or-nothing: on the machine in #454 a round trip took 3.3s, so
the call timed out every time, the list came back empty every time, and no
WSL distro was ever offered in the shell menu. Not slow — absent.

`Lxss` is where `wsl.exe` registers them, it is the same key
`default_wsl_distro` already reads for the same stated reason, and nothing
is listening on it, so it cannot hang. `wsl -l -q` stays as the fallback
for when the key will not open at all, which means this is not a machine
with WSL on it rather than a machine whose WSL is busy.

Windows Terminal made this move in 2021 (microsoft/terminal#10967) after
the same symptom — distros "missing entirely" on first launch. It skips
distros whose key carries `Modern = 1`; we must not. That is a
deduplication rule specific to Terminal, which modern distros hand a
profile fragment of their own. Nothing hands tty7 anything, and on an
up-to-date machine `Modern = 1` is the ordinary case — on the box this was
written on, the only distro installed. There is a test pinning that.

l0ng-ai c5a0d8665b perf(wsl): let a distro say once where its server is
`ensure_wsl_server` re-proved everything on every pane: uname, $HOME, a
stat, a liveness probe, a look at what is running — five serial `wsl.exe`
round trips to re-learn what the previous pane had just learned. Fine once
per distro, absurd per pane.

It now keeps the answer in memory, and nothing expires on a timer, because
the answer barely rots. A tty7 upgrade renames the binary, but a new build
is a new process and the map starts empty. A distro shutting down does not
invalidate it either: `wsl.exe` restarts a stopped distro on demand, and
the bridge starts its own daemon when none is listening, so the one claim
that really does stop being true is repaired a layer below without anyone
asking.

What is left is a path that could stop existing — the distro reinstalled,
the directory cleaned out. Starting the bridge is what discovers that, so
the router forgets the distro and proves it again from scratch, once. The
two operations that deliberately disturb what is running forget first, so
a restart that fails halfway leaves no note claiming otherwise.
2026-08-11 09:40:37 +08:00
l0ng-ai f676fb96de perf(wsl): stop asking twice whether a distro is ready
Every pane on a WSL workspace ran `ensure_wsl_server` from the client
before it even connected to the daemon — and then the daemon ran the very
same probe inside `router::open_link` before opening the link. Two full
rounds of five serial `wsl.exe` calls, to learn one fact.

The client's copy bought nothing. It threw the answer away and kept only
the error, which the route ack reports just as well; and the consent
question for a first install still finds its way here, because the daemon
runs its probe under `RouteSetup::blocking`, which installs the relay that
turns that question into a frame on this connection.

Measured on a distro that was already running and connected: 800ms to open
a tab, down to 440ms. Issue #454 is the same code on a machine where one
`wsl.exe` round trip takes 3.3s, where the duplicate was costing 15s a tab.

l0ng-aiandl0ng-ai 707fd1867b docs: add a Mintlify documentation site (#478)
38 pages under docs/, written against the source rather than the README:
config keys and their clamps from core::config, default keybindings from
ui::keymap, every CLI verb and flag from tty7-cli, agent aliases and
hook/fork/resume support from core::cli_agent, and Settings paths taken
from the actual en-US strings.

docs/features.md and its zh-CN translation are retired — everything in
them now lives in a page of its own, plus the two things they carried
that nothing else did (IME input, the performance notes). README and
README.zh-CN point at docs/ instead.

Screenshots and videos are placeholders for now: docs/images/placeholder.svg
with a caption naming what each shot should be.

l0ng-aiandl0ng-ai af3928da1e fix(tree-sync): pay back a remote window's owed tree pull (#472)
* fix(tree-sync): pay back a remote window's owed tree pull

A window opening onto a remote workspace is empty until `hydrate` pulls
the machine's tree and rebuilds its tabs from it, and it has to be: an
empty window diffs into "close every tab", so `sync_window` holds
anything back until the pull lands. When the pull fails,
`owe_rehydration` records the debt and returns, on the promise in its own
doc comment that the next sync settles it — "which is what a reconnect
does through `on_link_up`".

`on_link_up` is called for `HostId::LOCAL` and nowhere else. On a remote
host the debt was only ever settled by a reconnect completing, by an edit
in the window, or by restarting the app. So a pull that failed while the
link stayed up was never noticed again: no reconnect, and an empty window
has nothing in it to edit. The window sat on the home page with every tab
and every shell still on the machine, and only a restart brought them
back.

Two ways to fail a pull with a healthy link, both routine. A `MachineGet`
can overrun its ten seconds on a slow link. And a `WorkspaceCreate` can
lose its race with `start_prime`, which runs the same create from the
other side of the same window opening — that one fires on every remote
workspace opened, and is only invisible because the workspace it usually
lands on is empty anyway.

So: arm a backed-off retry when the debt is taken on, drive it through
`sync_window` where the rules about whether a window may still adopt the
machine's layout already live, and stop treating a lost create as a
failure — read the tree again and hydrate from what is really there.
`on_link_up` is also wired to a remote link coming up, which is what the
comment always claimed: a link the switcher connects finishes no attempt,
so nothing told its windows the machine could be reached.

* fix(tree-sync): end the backoff with the run of failures, and stop shouting

Review follow-ups on the owed-pull retry.

The attempt count paces the retry, so it has to mean "failures in a row",
but it was only cleared when a hydration landed. A debt abandoned rather
than paid — a `Replace` dropped because the user filled the window in
themselves — and a prime that landed both left it standing, so the next
first failure waited the 30s cap on an outage that was already over. It
is now cleared wherever the run ends.

A window left open on a machine that is really gone retries forever by
design, which meant a warn and an info every ~45s for as long as it stayed
open. Once the backoff settles at its cap those lines stop being events
and become a fact about the machine, so they step down to debug. The retry
is exactly as persistent; only the volume drops.

Also: report the create's own refusal when the reread finds the workspace
still missing, and say at debug that the reread happened at all — the race
recovery was silent, so the extra round trip was invisible when reading a
log. And correct the comment on the window-gone guard: closing a window
drops its whole `WsState` through `forget`, debt and all, so nothing is
parked for the next opener.

Tests: the count ends with the run at all three sites, the level steps
down at the settle point, and the armed retry is driven through a real
timer (advance_clock) into the window-gone guard — the first coverage of
the retry actually firing rather than of the predicate it consults.

l0ng-aiandl0ng-ai c216b389ae fix(macos): size the DMG ourselves, and stop blaming the runner's disk (#477)
The nightly channel has been frozen since 06:32 on 2026-08-10: every run
dies in bundle-macos.sh with "hdiutil: create failed - No space left on
device", on macos-15-intel, after the build, the signing and the
notarization have all succeeded.

The host disk was never full. #476 read that message as the runner running
out of room and freed space for it; the `df -h` it added to prove the point
disproved it instead — 105 GiB available, and the run failed anyway. The
path in the error is under /Volumes/tty7, which is the image being created,
not the runner: the volume ran out, not the disk.

`hdiutil create -srcfolder` sizes the image from the bytes it is about to
copy and does not cover what the filesystem spends carrying them, so a
bundle that fits by measurement still runs the volume dry partway through
the copy. It is a threshold rather than a cliff, which is why this began
without anyone touching packaging: the binaries grew over edfadb7..fafcaa0,
the x86_64 pair is the larger one and crossed it first, and arm64 kept
building fine just underneath.

Ask for the room explicitly — twice the content plus 64 MiB. The image is
compressed on the way out, so the slack is nearly free: on a stage of this
shape, 127 MiB of empty volume cost 672 KiB in the published DMG.

Also drop #476's deletion of the build tree. It was paying for a problem
that did not exist, and the bill was rust-cache finding nothing to save and
every macOS build recompiling the dependency graph. The `mv` from that
commit stays: a second full copy of the bundle is genuinely redundant, and
nothing reads dist/tty7.app after this point.

Verified locally against a staged bundle of the real shape (73 MiB, 101
files): the image is created, mounts with every file present, and detaches
clean. The remaining unknown is only whether CI agrees, which the next
nightly answers.

l0ng-aiandl0ng-ai 05ed9fa4ff ci(macos): give the DMG somewhere to go on a runner that ran out of disk (#476)
Three nightlies in a row died in bundle-macos.sh with "hdiutil: create
failed - No space left on device", across two different commits, always on
macos-15-intel and never on arm64. The build, the signing and the
notarization all succeed; the volume simply cannot hold the disk image on
top of everything already staged on it.

At `hdiutil create` the volume carries the whole release `target/` tree, the
signed dist/tty7.app, the compressed update zip, a second full copy of the
bundle under dist/dmg-stage, and the image being written. Two of those five
are avoidable:

Stage the bundle with `mv` instead of `cp -R`. Nothing reads dist/tty7.app
after this point — the updater ships the zip, nightly.yml verifies that zip
by extracting it elsewhere, and release.yml knows tty7.app only as an
intermediate to keep out of the upload globs.

Drop the build tree before the image is written. Every binary it produced is
already inside the bundle and no later step in either workflow reads it. The
cost is that rust-cache finds little left to save and the next macOS build
recompiles the dependency graph — a slower nightly, against no nightly at
all. `df -h` runs first so the next person to touch this has the number.

l0ng-aiandl0ng-ai 0f5e63701e fix(ui): let the overlay scrollbars fade out again (#471)
* fix(search): wash a match in the accent, at a strength the theme can afford

A search hit was washed from the terminal palette's selection colour at a
fixed 1.45:1 against the background, so it read as a weaker selection on a
grid that is already grey on grey — and 1.45:1 is under what a hairline is
worth, spread over a whole cell.

Two changes. The tint is now the theme's accent (`ActiveAccent`, already
floored at 3:1 by `legible_accent`), which is the one colour the terminal
surface has nothing else in. And the strength is derived per theme instead
of fixed: the wash is opaque with the glyph drawn on top, so what it may
spend is the theme's own text-contrast budget. A palette with 21:1 between
text and background can afford a wash you cannot miss; one with 6.6:1
cannot, and a single constant has to be safe for the second.

The current match drops its caret-coloured outline. That existed because a
fill 2.1:1 off the background could not say "this one" on its own; now that
it sits at the top of the theme's budget, the outline is the same colour
saying the same thing twice.

* fix(ui): let the overlay scrollbars fade out again

macOS reports should_auto_hide_scrollbars() = false for anyone with a mouse
plugged in, and apply_theme turned that into ScrollbarShow::Always for every
list in the app. That preference is about legacy scrollbars, which take a
gutter out of the layout; ours are overlay bars painted on top of the content,
so Always parked an opaque bar over the switcher's tab column for as long as
the panel stayed open, with nothing to fade it.

Pin scrollbar_show to Scrolling instead, so every list fades its bar out after
it stops scrolling.

and showed the moment the pointer was anywhere in the pane at all. It
was loud in the wrong places: a mark on top of the terminal wherever the
mouse happened to rest, and a target that moved while being reached for.

Cut to the shape Ghostty gives its grab handle instead:

* three dots, 80x12 of reach around them, and nothing between the two
  states but ink — 0.3 in the band, 0.8 on the grip itself.
* the dots are asked for by the pane's top fifth (floored at 24px), not
  by the whole pane, so the terminal is left alone everywhere else.
* the target is there for as long as the pane can be moved, and only the
  dots come and go, so a pointer going straight for the top of a pane can
  press the grip on the frame it arrives.
* a 150ms fade in, so the dots read as arriving rather than blinking.

The fading a pane is under is now worn by the terminal it holds rather
than by the pane, which keeps the grip legible on the very panes
`dim_inactive_panes` fades — the ones being reached for.

l0ng-aiandl0ng-ai 425f87e9a4 fix(core): key the machine tree to the config directory (#462)
* fix(core): key the machine tree to the config directory

The tree resolved from $HOME while everything else an instance owns —
views.json, the scrollback, the history, both sockets, the pidfile, and
daemon.lock — resolved from the config directory. So --config-dir moved
every part of an instance except the one that says which workspaces
exist, and two tty7s pointed at different config directories, each
holding its own lock and each certain it was the only server on the
machine, still co-owned one ~/.local/share/tty7/machine.json.

MachineStore::persist writes the document whole. The second one to flush
replaced the first one's workspaces with its own, and the next daemon to
start read the survivor's tree as the machine's. An empty tree is not
distinguishable from a machine that really has nothing on it, so the GUI
does what an empty tree means and forgets those workspaces for good.

A lock and the thing it protects have to be keyed alike. data_dir() now
follows the config directory; TTY7_DATA_DIR stays as the highest-priority
override so the test harnesses keep their sandboxes.

Moving the path without carrying the file would lose every workspace at
the moment of upgrade, which is the failure this change exists to stop,
so the daemon adopts the legacy file on startup before it opens the
store. The destination already existing is the whole guard: it means a
newer run owns the tree and the copy at the old path is stale, from a
build that predates the move and still writes where it believes the tree
lives. Adopting that over the live file would hand the old tree back.

* fix(core): only the machine's own instance inherits the legacy tree

The migration moved `machine.json` into whichever config directory started
first. In the very setup this change exists to fix — a default install beside a
`--config-dir` one — that is the second instance renaming the machine's tree
into its own directory, leaving the primary to come up owning nothing. It also
fired in our own test suite, where `routed_pane` and friends launch a real
`tty7-server --config-dir <TempDir>` under the developer's own `HOME`.

Adoption is now the entitlement of the instance running out of the config
directory this machine resolves to on its own: `$TTY7_CONFIG_DIR` where the box
names one, `$HOME`'s otherwise. Comparing paths rather than asking whether
`--config-dir` was passed is what keeps the ordinary install working — `spawn`
hands every daemon it starts an explicit `--config-dir`, its own included — and
counting `$TTY7_CONFIG_DIR` is what keeps remote hosts upgrading, since a remote
`tty7-server` is launched without the flag and finds its directory that way.

Also tightens the cross-filesystem fallback: a rename that failed because
another process already carried the file over is the one benign race, not an
error to report and not something to copy over. What is left copies through
`create_new`, so "never overwrite what is already there" holds against a racing
writer and not merely against an `exists` check several syscalls old, and a
write that does not finish leaves nothing behind.

Tests: the gate both ways, the appearance hint riding along, the same directory
under two names, the copy path refusing an occupied destination, and two
cross-process cases in `machine_tree` that start a real server under a scratch
`HOME` — one carrying the legacy tree in, one leaving it alone.

l0ng-ai d223818e1b Merge pull request #461 from l0ng-ai/fix/scrollback-restore-survives-restart
fix(daemon): give a restarted server back its panes' shells and screens
2026-08-10 16:46:52 +08:00
l0ng-ai a55340ed7f fix(daemon): sweep a dead daemon's leavings on the writer's tick, not at startup
Review follow-ups on this branch.

`history::sweep` still ran at startup, three lines under a new comment
explaining why sweeping there is wrong. The reasoning transfers exactly, and
worse than by analogy: a restore carries the dead pane's commands to its
successor via `history::carry`, so sweeping before the window can ask deletes
the file the request is about. Same shape as the scrollback bug, one file over.
Both sweeps now run on the writer's tick off one shared id set, and the writer
is named for what it does.

`pane_attachable` lost its only caller when the restore path moved to
`pane_free_for`, leaving a function kept alive by the test asserting on it. The
attach site does not need to predict the listing: it tries the attach, and a
pane that is gone falls through to the fresh spawn on its own. Gone, with its
tests folded into `pane_free_for`'s.

`restored_screen` now drops the snapshot in both directions. Keeping the file
when it decoded to nothing left it to be re-read and re-rejected by every later
restore, and swept never, for a pane the tree still names.

Also: the module doc still said scrollback was off unless asked for, which is
what this branch reverses; and #449 landed the whole feature with no CHANGELOG
entry, so nothing told anyone that pane output now lives on disk.

l0ng-ai b3a66e75d0 fix(test): let the machine-tree seed keep up with a new pane field
PaneSeed grew a `shell`, but this test is unix-only, so a Windows box
never compiles it and never says so. Build the seed from `bare` and the
next field lands on its own.

l0ng-ai 477d82524f feat(daemon): keep every pane's screen, without asking
`persist_scrollback` is gone, and with it the switch, its three
translations and the branches that read it. Keeping a capped tail of
each pane's output is now what the daemon does, not something it can be
asked to do.

This reverses the call made when the feature landed. The argument for
off-by-default was that the ring holds whatever the pane printed —
echoed tokens, `env` output, an agent's transcript — and that writing
that down should be the user's decision to make. What the argument
missed is when the decision gets made: the moment anyone learns they
wanted this is the moment a daemon has already died, and by then the
setting could only be turned on for next time. A feature whose entire
purpose is to survive an event nobody schedules cannot be opt-in.

The cost is real and does not go away: pane output now lives at
`<config>/scrollback/*.bin` on every machine, 0600 on unix and behind
the config directory's ACL on Windows, capped at 256 KiB per pane and
dropped as soon as no window can still ask for it.

Old configs naming the key still parse — nothing in `Config` refuses
unknown fields — so the key simply stops meaning anything.
2026-08-10 16:06:54 +08:00
l0ng-ai 412bfcfc90 fix(session): let a dead pane keep its id so its screen can be asked for
`pane_attachable` answered one question and was used for two. Deciding
whether to attach needs to know the pane is alive; deciding which dead
pane a fresh one replaces needs only its id — and that is the case the
stored screen exists for.

Using the first answer for the second was self-defeating. After the
daemon restarts, every pane the window held is missing from the new
daemon's listing, so the id was ruled out, so `restore_pane` was `None`,
so the window spawned a pane that had never heard of a predecessor. No
attach was tried, no restore was requested, and the screen the daemon
still had on disk was swept a tick later without anyone reading it. The
setting was on, the snapshot was written, the daemon was ready to hand
it over, and nothing ever asked.

Ownership still rules an id out, because another workspace's pane is
neither ours to attach to nor ours to show. Liveness no longer does:
the attach is still tried first and still gives way to a fresh spawn
when the pane really is gone, which is the arrangement the tree path
already argues for at length — `live` is a hint about what to show,
never the judge of what to destroy.

l0ng-ai 3093babddd fix(pane): say when a restore is not asked for
Dropping the request here produced a blank pane, which is also what a
pane with nothing stored looks like and what a daemon that refused would
produce. Three causes and one appearance, with nothing anywhere to tell
them apart — the filter was silent, so reading the source was the only
way to find out which had happened.
2026-08-10 16:06:54 +08:00
l0ng-ai c138be687a fix(daemon): keep a pane's shell and its screen across a restart
Two things a pane lost when the background service stopped and started,
both of them things the tree was the only possible place to keep.

**The shell.** `PaneRecord` and `PaneSeed` carried a pane's cwd, its ssh
spec and its agent, but never what it was running. A window rebuilding a
dead pane from the tree therefore had nothing to pass and spawned on
whatever the default shell is now — so a restart turned a bash pane into
a PowerShell one, quietly and in place. The daemon resolves the override
against the config at spawn time and is the only party that knows the
answer, so it keeps it and reports it; the seed carries it too, for the
panes a window spawned itself. A handoff carries it in the blob, because
nothing on the far side of an `execve` can work out the command line of
a child it never spawned.

**The screen.** The startup sweep ran before the endpoint was listening,
which is the one moment nothing can answer the question it asks: the
registry is empty and the windows that know which screens are still
wanted cannot say so yet. A tree that failed to parse made it worse —
`read_machine` quarantines it and returns an empty `Machine`, so one bad
file took every pane's stored screen with it. The sweep now happens only
on the periodic pass, a tick later, with the registry filled in and the
tree caught up; nothing is serving a request in between. Turning the
setting *off* still clears the directory at once, because there the
promptness is the whole promise.

Two smaller ones alongside it: `restorable_pane_ids` now counts the
tree's pane list and not only the panes some tab currently stands on —
the two disagree while a window is between layouts, and being wrong
costs a file swept a tick late in one direction and somebody's terminal
in the other. And `restored_screen` drops the snapshot file *after*
deciding it was not empty, so a snapshot holding nothing is no longer
consumed by the request it could not answer.

The restore path had no end-to-end test, which is how this shipped: the
unit tests cover the file, not whether a window that reattaches is shown
anything. The new one runs a real daemon, puts a marker on a real pane,
stops the daemon, starts another, and reads the wire.

l0ng-ai edfadb7df2 Merge pull request #424 from l0ng-ai/feat/scm-foundation
feat(scm): a full Source Control panel, decorations and commit history
2026-08-10 14:12:21 +08:00
l0ng-ai 2dc6a88af6 merge: main into the Source Control branch
Conflicts were the two streams touching the same seams, resolved by
taking the newer decision on each side:

- main's interface font scale (rems tokens) wins in right_panel.rs; the
  SCM panel keeps its local px steps until it moves onto that scale,
  and the now-unused PANEL_TEXT constants are gone.
- main's l10n_keys! macro (idents only) means the key list carries no
  doc comments any more; our SCM keys fold into it, and PanelUntracked
  stays deleted — its only caller was the panel this branch replaced.
- main's Command::localized palette style carries our Git group; ORDER
  keeps main's visibility and our width.
- main's ansi_seed/clear_ink refactor in presets.rs carries the lane
  colours: lanes() now clears through the same helper semantics uses.
- file_tree keeps both: main's drag-and-drop targets and this branch's
  git decorations per row.
- diff_overlay keeps both: main's sidebar-count write-back on snapshot
  install and this branch's epoch read and untracked preview.
- main's window.prompt SSH-close confirmation supersedes the bespoke
  modal our branch still carried; main's tile-glyph revert stands.
- main's two new guards are satisfied: the fourteen SCM actions carry
  authored names on the Keybindings page (their palette wording, plus
  a new CmdGitToggleGraph), ja translates ScmDetached, and CmdGroupGit
  joins the kept-in-English list — Git is a name.

l0ng-aiandl0ng-ai 9815f2d16f fix(windows): restore Ctrl+C in panes (#459)
The daemon was created with CREATE_NEW_PROCESS_GROUP, which disables
Ctrl+C for the whole new group — and Windows hands that "ignore Ctrl+C"
state down to every descendant. Every ConPTY shell a pane spawned
inherited it, and so did everything those shells ran: the pane wrote 0x03
and conhost turned it into a keypress, but the CTRL_C_EVENT never came,
so `go run` and `npm install` carried on. Git Bash looked fine only
because MSYS synthesises SIGINT from the byte itself and never waits for
a console event.

DETACHED_PROCESS already leaves the daemon without a console for a
control event to arrive on, so the group flag bought nothing to begin
with. Both daemon spawn paths and tty7-cli's headless server — which
spawns panes too — now share one constant without it, and
DaemonPane::spawn clears any inherited ignore before it opens the pty, so
a tty7 launched from a shell that already had the bit set is covered as
well.

The regression test has to inherit the state rather than switch it on in
place, since that is the shape the daemon was in: an intermediate process
created exactly as the daemon used to be runs both arms, and a pane must
be interruptible only after the clear. Its observable is the shell rather
than the interrupted command — after the ^C, cmd gets its prompt back and
acts on the `exit` typed behind it — so it reads no message and holds on
a non-English Windows.

l0ng-ai feb027da1f feat(scm): show an untracked file's content when its row is opened
Focusing an untracked file in the diff overlay used to fall through to
the names-only "Untracked files (N)" card — git has no patch for a
file it does not know, and `--no-index` needs a null device whose
spelling is platform business. The overlay now reads the file's own
bytes (lazily, only the focused file, 4 MiB cap) and synthesizes the
card a parsed added-file patch would produce: every line an addition,
new-side numbers, true counts past the single-file budget, git's own
NUL-in-the-first-8000-bytes binary rule. A fresh snapshot clears the
preview so an edit shows up on the same cadence a tracked file's does;
a failed read says so instead of showing an empty file.

Found in manual acceptance of the panel.

l0ng-ai 1df43b72b5 feat(files): copy dropped files into the folder they were dropped on (#458)
* feat(files): copy dropped files into the folder they were dropped on

The Files panel has only ever been a drag *source* — a row dragged into a
terminal inserts its path. Nothing on the tree ever registered a drop, so
a file dragged in from the desktop did nothing at all, not even a
highlight. Closes #453.

The drop is the whole gesture: files land where the cursor was, not
somewhere a dialog asks about afterwards. A folder row takes them itself,
a file row stands in for the folder holding it — "next to this one" — and
the space the rows do not cover belongs to the top of the tree. The
placeholder inside an empty folder takes a drop too; it is the only thing
drawn there, and letting it fall through to the root would put files
somewhere the cursor never was. A row under the cursor wins over the
column, which is what gpui's innermost-first dispatch already does.

The copy itself goes through the `Host` the tree is listing, so a remote
workspace reads here and writes there. Locally it is `fs::copy`, which is
what keeps the executable bit that `write_file` would drop; remotely the
bytes ride one control frame, and a file too big for that is refused with
the advice to use SFTP rather than half-sent.

Names already taken are asked about before anything is written, and the
answer governs the whole drop — a half-done copy would have to be undone
to honour a "no". Replacing a folder replaces it rather than merging into
it. A drag let go where it started is a miss, not an error, so it says
nothing.

* fix(sftp): list the directory again once an upload lands

An upload is written to `<name>.tty7-upload-<hex>` and renamed into place
at the very end. The browser listed the directory the moment the transfer
was handed to the daemon, so it caught that temporary name — and nothing
ever listed again, so a finished upload sat on screen as a file with a
hash glued to its name until the directory was navigated by hand.

The premature listing is gone, and the panel now remembers the job ids it
started: once one stops running — done, failed, cancelled, or dropped off
the job list entirely — the directory is listed once more. Two uploads in
flight settle independently, so the second one finishing does not depend
on the first.

* docs(changelog): note the SFTP upload listing fix

* ci(host-boundary): allow the source side of a file drop, and stop scanning two files as empty

The Files panel now copies dropped files in, and what the desktop hands
over is by construction a path on the desktop's own machine: reading it is
a local read even when the tree being dropped on is remote. The
destination side goes through `Host`, and the one `std::fs::copy` that
touches a destination sits inside a branch already gated on
`host.id().is_local()`.

While adding that entry: `attr` starts unset, which awk reads as 0, so a
file whose first line is `mod something` matched `attr == NR - 1` and cut
its body at line 0. `head -n -1` then errored and the file was scanned as
empty — `src/terminal/mod.rs` and `src/ui/tray/mod.rs` both open that way,
and the guard had been blind to both. Neither contains a violation, so
seeing them is free.

l0ng-ai 58d7ef5838 fix(scm): close out the review's minor findings across the data and UI layers
The second pass over the branch review: every remaining finding verified
against the code, the real ones fixed.

Data layer:
- A truncated log parse is never called complete: RecordSplitter drops
  an overlong record whole and reports the count (delivered cut short,
  a commit body cut mid-way reads as the real message), parse_log
  carries a truncated flag past MAX_LOG_BYTES, and load_page only says
  "end of history" when the parse read everything git returned.
- Every scope pins symbolic revs to shas before walking, so a commit
  landing between two pages can no longer shift where page two starts
  under Head and Refs scopes; unresolvable names read as "no history"
  rather than as a load failure. --parents was doing nothing and is
  gone; edge sort is stable so a merge's Outs keep first-parent order.
- The lane model's central invariant now names the join case — a merge
  whose second parent already has a lane reserved sends its Out onto
  that lane, one line below the cut, not two — with a golden test for
  the commonest merge topology of all, which no golden covered.
- DiffSource revs get the same could-be-an-option guard log already
  had; C-quoted paths decode the full escape set (a tab decoded to a
  literal t broke the :(literal) re-probe); rename from/to lines
  override the ambiguous diff --git header; combined-diff line numbers
  follow the sides rather than the colour, so a " +" line no longer
  drifts every number below it.
- A rename's old path stays out of the per-file decoration map, where
  it outranked a file re-created at that path; ignored records decorate
  as Ignored, not Modified; checkout <branch> gains the trailing --
  that keeps a stale name from falling back to a worktree-clobbering
  path checkout; unstage before the first commit takes -f (worktree-
  safe with --cached); batches split by bytes as well as count for
  Windows' 32K command line; a deadline expiry reports Timeout, not
  "git could not be run"; error details keep both streams.
- probe_status distinguishes "not a repository" from "could not ask":
  a dropped link keeps the cached status (stale beats blank) and rests
  10s instead of erasing the panel, while a definitive not-a-repo also
  drops the cwd→root mappings so the panel stops drawing Loading for a
  repository that is gone. Probe and watch work are wrapped against
  panics that would wedge their in-flight bookkeeping forever, watch
  landings check the wipe counter, superseded probes relaunch through
  the debounce, and a refused network slot says so instead of eating
  the click.

UI:
- Reset --hard confirms with its own words (commits fall off the
  branch), not the discard dialog's; a merge commit whose prefilled
  message the user cleared is committable again; the disabled commit
  button distinguishes "nothing to commit" from "write a message".
- Selection highlight matches on the diff source too, so a file staged
  and edited again no longer lights both of its rows for one overlay.
- The graph materializes only the rows in the viewport window (5000
  flex children per frame was most of a frame), row clicks carry the
  page Arc and an index instead of a deep Commit clone per row per
  frame, filter results are cached per (page, query), and a selected
  merge ring's hole matches the selection band under it.
- A failed commit_files read says the list could not be read instead
  of "0 files changed"; the STAGED chip and the graph's relative
  times go through the i18n table; the keys-awaiting-a-caller list is
  pruned to the seven that still are; the orphaned PanelUntracked key
  is gone; the zh commit placeholder reads naturally.

2398 tests, 0 failures. Known flake: daemon::singleton's second-claim
test, untouched by this branch, fails ~1 in 3 full parallel runs and
passes alone.

l0ng-aiandl0ng-ai 5f1ee966ec fix(windows): give the pane grip and drags in flight a cursor (#455)
Win32 ships neither an open- nor a closed-hand cursor, and gpui's Windows
backend answers both with the plain arrow. The pane drag grip asked for
`cursor_grab()` and so read as ordinary background there, and the pointing
hand the sidebar's group header had worked around it with was dropped again
the moment a drag began, since the active drag cursor is `ClosedHand`.

Lift that workaround into `reorder::cursor_grab` so the grip and the group
header share one answer, and pick the held cursor per platform too.

l0ng-ai a764d92132 fix(scm): sequence compound verbs, cap graph paging, back off failed loads
Review findings on this branch, all in the seams between async operations:

- Commit-and-push, commit-and-sync, sync and discard-all dispatched both
  halves into the worker pool at once, so a push could resolve the branch
  tip before the commit (or pull) it was waiting for and quietly send the
  old one. Compound verbs now carry a ScmFollowUp that the first half's
  landing closure starts on success only; a refused commit, a failed pull
  or a cancelled confirmation drops the follow-up with it.
- Push sent `git push <remote> <branch>` with the branch taken from the
  upstream's name — a bare name means a *local* branch, so `feat`
  tracking `origin/main` pushed stale local `main`. The refspec is now
  `HEAD:<branch>`, and the branch is validated with the full branch
  check since a `:` would smuggle a second refspec in.
- `scm.committing` was armed before the amend confirmation and never
  disarmed on failure, so a cancelled prompt (or a hook rejection) plus
  any later unrelated HEAD move cleared a message that was never
  committed. It is armed at dispatch and disarmed when the commit errors.
- Discard-all fed staged-only paths to `checkout --`, where a staged
  deletion sank the whole batch as an unmatched pathspec. Only unstaged
  paths go in, one confirmation covers both halves, and the two gits no
  longer run concurrently.
- One "load more" click at 5000 commits grew `requested` past what
  `load_page` clamps to, so the freshness check never passed again and
  every frame refetched the full page. Growth stops at the cap, the
  button hides there, and a failing `git log` is remembered per key
  instead of being retried from every render.
- A repository switch now drops the previous repository's page before
  anything can draw it or grow from it — a stale row's context menu
  used to build ops for the new repo with the old repo's rev.
- A watch that failed to open was retried at frame rate, one host round
  trip per render; it now rests for WATCH_RETRY between attempts.
- Non-network writes on a remote host ran under the interactive
  20-second deadline while the server ran the job to completion, so a
  slow pre-commit hook was reported failed and then landed anyway. Every
  write now goes through git_with_deadline, 120s for local verbs.

l0ng-aiandl0ng-ai 30b16c65b5 fix(settings): keep one restart button for the stale background server (#452)
The in-place-update notice carried its own Restart server button while the
Server section right below it carried an identical one, both calling
restart_daemon. Move the notice into the Server section: the stale build
line sits under the header and its explanation replaces the generic one,
so the single button that ends every running pane is the only one on the
page.

l0ng-aiandl0ng-ai 88bf9a5da5 feat(daemon): upgrade in place, keep pane screens across a crash, and give panes their own history (#449)
* feat(daemon): keep a pane's screen across a death nobody chose

A daemon that crashes, is `kill -9`'d, or goes down with the machine takes
every pane's replay ring with it, and the window comes back to a row of
blank shells. The processes cannot be saved that way — nothing written to
a file brings a process back — but the picture can.

The daemon now keeps a capped tail of each pane's ring under the config
directory, and a client whose `Attach` found nothing can ask, on the
`Spawn` that replaces it, for the dead pane's screen. The new pane opens
showing it, under a rule that says the shell below is new.

- periodic and dirty-only: a ring that has not moved is not rewritten, so
  an idle machine does no IO at all. Write-through would be an enormous
  amount of write amplification for a few seconds of freshness.
- capped at 256 KiB per pane, far below the ring's 8 MiB: the value of
  scrollback decays with distance from the bottom, and every byte here is
  a byte of someone's terminal on disk.
- off by default. The ring holds whatever the pane printed, including
  echoed tokens, `env` output and agent transcripts; in memory that dies
  with the daemon, and writing it down is the whole feature and the whole
  cost. Files are 0600, and turning the setting off deletes what was kept.
- dropped by relevance, not by calendar: a pane the user closed, or one no
  workspace names any more, has its file removed on the next sweep.

Restored bytes are replayed at the geometry they were written at, and are
preceded by resets — leave the alternate screen, show the cursor, restore
autowrap, clear SGR — because a snapshot is cut at the front and can begin
in the middle of any of them.

* feat(daemon): upgrade the daemon in place instead of killing every shell

Picking up a new build meant stopping the daemon, and stopping the daemon
means every pane dies: the pty master is a descriptor this process holds,
so when the process goes the slave side raises SIGHUP and takes the shell,
the agent and the half-finished command with it. That is why the update
path leaves the old daemon serving and Settings has to offer the restart
as a thing you schedule for a quiet moment.

`execve` does not have that problem. It replaces the image and keeps the
process: same pid, same children, same descriptors, same file locks. The
daemon now rewrites itself that way on `ClientMsg::Handoff` — it writes
what it knows about each pane into a blob, clears FD_CLOEXEC on the pty
masters, the blob and the singleton lock, and execs the new binary, which
picks the panes back up on the other side.

- **the seat travels on the command line, not in the blob.** The lock is
  still held by this process, so the new image must adopt the descriptor
  rather than ask for the lock again — asking would be refused by its own
  lock and it would stand down in favour of itself. A daemon that loses
  its panes is a bad afternoon; a daemon that exits leaves the machine
  with nothing serving, so that one fact has to survive an unreadable blob.
- **the blob is unlinked before it is written.** It holds every pane's
  ring, which is the output `scrollback` makes people opt into storing;
  a handoff must not be a back door for writing it to disk.
- **the exec is the last step.** Everything is staged first, so any
  failure before it costs a log line and the daemon carries on serving —
  which is what lets callers treat a failed handoff as "fall back to a
  restart" without having lost anything on the way.

Native SSH panes cannot cross — their session is cipher state in memory,
not a descriptor — so they are hung up first and the far end sees a clean
close. Windows has neither execve nor a transferable ConPTY handle, so it
keeps the stop/start path; the dialogs there still promise what they
always did, and the new copy is shown only where it is true.

Also retries flock on EINTR: a signal landing mid-call said nothing about
the lock, but was reported as "could not be evaluated", which starts a
second daemon beside the first — the split machine singleton exists to
prevent.

The end-to-end test sets a variable in the shell, hands over, and reads it
back. Nothing but the original process can answer that, and the daemon's
instance id changing while its pid does not is what says an exec really
happened.

* feat(shell): give each pane its own history when asked

Two panes running zsh with `share_history` are appending to one file and
reading each other's lines back, which is either the feature or the
problem depending on what the panes are for. Someone with a pane per task
wants Up to walk that task's commands, not an interleaving of four.

Each pane can now have its own history file instead. It is seeded from
the shell's real history, so a new pane is not blank, and what the pane
added is appended back when it closes, so nothing typed is lost — a
per-pane history that evaporated would be a way of losing commands, not
of organising them.

The seeding is done by the shell, not the daemon, and that is the only
reason it works: `HISTFILE` belongs to the user's rc file and can point
anywhere, long after the pane's environment was decided. tty7's snippet
is appended to the rc it wraps, so it runs after that decision and is the
one place the real path is known — it copies the tail, records how much it
copied, and repoints. Both shells load history after their startup files,
so the switch lands before the first line is read.

The daemon's half is a filename, a rename when a restored pane inherits
its predecessor's file, a merge on close, and a sweep for the panes a
killed daemon never got to retire.

Off by default: shared history is what a terminal has always done, and
someone who did not ask for the change would experience it as their
history mysteriously forgetting the other window. bash and zsh only —
fish and PowerShell do not keep a HISTFILE, and a shell launched with the
user's own arguments gets no snippet to repoint anything in.

* fix(daemon): store pane screens on the shutdown a restart actually uses

The periodic writer covers a death nobody prepares for and the SIGTERM
path covers a signal, but the restart the app itself performs goes through
ClientMsg::Shutdown — which killed every pty without taking a copy first.
That is the one shutdown where the panes are expected back.

* fix(daemon): leave nothing dangerous behind when a handoff fails or lands

Review findings on the in-place upgrade and per-pane history:

- A failed exec now puts back everything it had staged: FD_CLOEXEC on the
  seat and every pty master (a child inheriting the seat keeps the flock
  held past the daemon's death, so no future daemon could seat itself),
  and the SIGPIPE disposition plus this thread's signal mask, both of
  which Command::exec resets on its way to the attempt — without this,
  the still-serving daemon dies on the first client that hangs up
  mid-write.
- The adopting image restores close-on-exec on the seat and on every
  adopted master, so children it spawns later cannot hold a pty open
  past its pane, or the seat past the daemon.
- The target binary is checked before the handoff gives anything up:
  native-SSH panes are hung up on the promise that this process is about
  to be replaced, and an exec that was never going to work must not
  collect on it.
- The integration snippets raise HISTSIZE/HISTFILESIZE (bash) and
  SAVEHIST/HISTSIZE (zsh) for the pane's private history file. At their
  defaults the exit rewrite truncates the file below its own seed mark,
  which the merge-back rightly reads as "replaced under us" — silently
  losing the pane's commands for anyone with more history than the caps.
- The restart dialog's promise now binds the action: where the copy said
  "nothing is interrupted", a failed handoff is reported instead of
  silently traded for the restart that kills every pane.
- The scrollback writer checks the ring's mark before cloning it, so an
  idle pane no longer costs a full ring copy under the state lock every
  tick.

Each behavioural fix carries a test that fails without it; the history
truncation one was verified to fail with the snippet change removed.

l0ng-ai 44f0683d0a fix(sidebar): cut labels on grapheme clusters, not on chars (#450)
The sidebar's elision measures against real glyph widths but slices by
`char`, so it can satisfy every width check and still hand back a torn
cluster. Scanning budgets from 30px to 200px over emoji fixtures, 48
widths produced output no font can render as intended:

    "release-…\u{200d}👩\u{200d}👧"   a joiner with nothing in front of it
    "lon…\u{fe0f}"                    the variation selector lands on the ellipsis
    "abcdef…🇳ghijklmnopqr"           half a flag, which renders as a bare N

A tab title carrying an emoji is not exotic — plenty of TUIs and coding
agents put one there — and the second case is the same U+FE0F this repo
already carries an alacritty patch for.

`elide_keep_edges`, the tail-only fallback, and `short_title`'s 40-glyph
clamp now index grapheme clusters. `elide_path_keep_tail` cuts on `/`
and was already safe. Widths are unchanged: clusters are measured the
same way chars were, so every existing elision test still passes on the
same fixtures.

`unicode-segmentation` is already in the tree via gpui; pinning it here
adds one line to Cargo.lock and no new code.

Tests assert the property rather than the symptom: whatever survives on
either side of the ellipsis has to be a cluster-aligned prefix and
suffix of the input. That catches any tear, not just the three shapes
found here. Written first, confirmed failing on all three cut sites, and
green after.

ARNOandl0ng-ai 1fd99ca7c6 feat(sidebar): tail-first label elision and a hover card for hidden details (#446)
* feat(sidebar): tail-first label elision and a hover card for hidden details

ff

* fix(sidebar): keep the head of a non-path label, and let the card expand what the row hid

The elision landed with four gaps between what a row hides and what the
hover card can give back.

A renamed tab is elided like anything else, but `sidebar_info` still
carried the old tooltip's guard and bailed out on any non-empty
`tab.name`, so a long custom name was shortened by the row and the card
refused to spell it out. An empty terminal title took the opposite path:
the row falls back to `Shell 3`, the card compared that placeholder
against the empty string it came from, found them different, and opened
on a row that had hidden nothing. Both came from deriving the same
strings twice; the row now hands `sidebar_info` what it rendered next to
what it rendered it from, and the card is decided by comparison alone.

`elide_path_keep_tail` was applied to every title, but a title is not
always a path — `npm run dev`, or a name someone typed. Dropping the
head of those says less than the truncation this replaced, so
`elide_label` picks the rule: tail-first for a path, both edges
otherwise.

`elide_keep_edges` promised both ends and delivered neither on a token
with no break in reach: the head ran to the 12-glyph cap, `head…` alone
overran the budget, and it fell through to a bare tail. It now tries
shorter heads before giving up, and never trades the whole tail away for
a longer head (`feature/…` became `fea…thing`).

Also: measure the active row at the MEDIUM weight it actually renders
at; subtract the list's own padding from the text budget, so a label
that "just fits" is not handed back to CSS truncation; rejoin a path
with the separator it arrived with, instead of spelling one tab
`C:\Users\dev\app` while it fits and `C:/…/app` once it does not; count
the gap between the two diff counts rather than the space standing in
for it; let the card wrap instead of truncating the one string it
promised in full; and read the remote host off the same leaf the title
came from.

The elision tests shape through gpui's `NoopTextSystem`, where every
glyph is one em — deterministic across the three CI targets, but blind
to the proportional and CJK widths this exists for. Said so where the
fixtures are built, rather than implying the pixels are real.

l0ng-aiandl0ng-ai 86799220ca feat(splits): rearrange a tab's panes by dragging one onto the layout (#445)
* feat(splits): rearrange a tab's panes by dragging one onto the layout

Hovering a pane floats a small grip along its top edge; dragging it picks
the pane up and puts it somewhere else in the same tab. Three landings,
resolved from where the pointer is:

* a pane's edge — split that pane and take the side dropped on
* a pane's middle — trade the two panes' places
* the band along the outside of the tab — sit beside everything else as a
  full-width or full-height band, which is the only way to say "make this
  a full-height column" in one gesture from the middle of a 2x2

The landing is highlighted while the drag is in flight, and is offered
only once the tree agrees the drop changes something, so the highlight is
never a promise the drop does not keep.

* pane: move_leaf / move_leaf_to_edge / swap_leaves, each built on a clone
  and installed only when the layout really differs
* pane_drag: the pointer-to-landing geometry, the drag state, and the grip
* tree_sync: reconcile a tab that kept its panes but changed shape with a
  single PaneMove instead of closing and rebuilding the tab

* feat(splits): drop a pane beside its neighbours, not on top of one

Trying the drag out on real layouts turned up three ways the drop model
asked for more precision than it should have.

A drop on a pane's side always halved that pane, so putting a new column
into a row of columns was only reachable at the very edge of the window,
where the band rule took over. A side facing a neighbour in the same row
or column now joins that run: the newcomer takes an equal share and the
others give it up in proportion, keeping whatever relative sizes they
were dragged to. A side facing across the run has no run to join and
still halves the pane it landed on.

The band along the tab's edge was a flat 26px, which on any real window
is a hair's breadth. It is now measured against the pane it is read in —
a sixth of it, floored at 32px and capped at 120 — and only counts on a
side that faces the window rather than another pane. Landing there takes
an even share of the columns that side already has instead of half the
tab, so a third column is a third and not a half.

The highlight is no longer drawn from the rule. The drop is carried out
on a deep copy and the dragged pane's new rectangle is measured off it,
so the preview and the result cannot disagree; the copy is deep because
sharing a run out writes ratios the live tree's splits hold in common.

Also: the grip is a quiet 22x3 bar that grows to 40x5 under a fixed
56x10 target (it needs an id of its own, or gpui settles its size before
the group-hover is known), and every rearrangeable pane keeps an 8px
strip clear above its grid so the grip never sits on the first row.

* fix(splits): pin a drop to the pane it was offered against

Review follow-ups on the pane drag.

A drop zone named its target by position in the tab's leaf order, but it
is read on one frame and carried out on the next: a pane closing in
between shifts every index after it, and the drop lands beside a pane the
user never aimed at. The zone now carries the target itself once the
frame that drew it has resolved it, so a target that has gone refuses the
drop instead of sliding it sideways.

Alongside it:

* `Pane` is no longer `Clone`. The two copies it can be asked for differ
  in whether they share their splits' sizes, which is not a difference to
  leave to whichever one `.clone()` happens to mean; `shallow_clone` is
  now named and private, next to `deep_clone`.
* `edge_landing` no longer hands back a share that only a test read. The
  test reads it off the split the landing produced instead, which is the
  number the drop actually lands.
* A test pins the invariant the drop zones rest on: `leaf_rects` comes
  back in the order `leaves` does.
* Drop a doc comment that had landed on `close_focused` describing a
  different method, and an `Option` in `drop_pane` that was wrapped only
  to be unwrapped two lines later.
* The changelog claimed every rearranged tab now syncs as one `PaneMove`.
  Only a drop beside a single pane does; a drop beside a whole group is
  not something `PaneMove` can name, and still takes the rebuild. Both
  entries move under `Unreleased` — v26.8.2 was tagged before either
  landed.

of the last character of 窗口与标签页. Size the floor for ja-JP
ウィンドウとタブ, the widest of the three, which costs the page 35pt at the

l0ng-aiandl0ng-ai c13efbce32 fix(terminal): draw a multiline history entry on one menu row (#436)
A command composed in the inline editor keeps its newlines when
`submit_command` pushes it into the in-session history, even though
`history::append` and the zsh/bash/fish parsers all refuse to carry an
entry across lines. gpui breaks text on `\n` whatever `white_space`
says, so one such entry painted a dozen lines inside a one-line row and
covered the whole reverse-search menu.

Fold line breaks to a visible `↵` when drawing — one char for one char,
so the fuzzy matcher's highlight positions still line up — and leave the
stored entry untouched, so recalling and running it are unchanged.

Remove `claude-code-review.yml` and `claude-review-fork.yml`. Both are
advisory-only and never gated a merge, so the required checks on main
stay exactly `rustfmt` and the three `build & test (<target>)` jobs from
ci.yml.

Nothing else references them: the `claude-review` label and the
CLAUDE_CODE_OAUTH_TOKEN secret were used only by these two files.

l0ng-aiandl0ng-ai 8dbc7efa1a fix(cli): stamp panes with the workspace that holds them, not the client's name (#425)
* fix(cli): stamp panes with the workspace that holds them, not the client's name

A pane's owner names the workspace allowed to attach to it. The CLI wrote
a literal "tty7-cli" there for every pane it made, so a window opening on
a CLI-built workspace found none of them attachable: it spawned a fresh
shell for each tab, orphaned the live ones, and — because the tree still
carried each pane's agent session — greeted the user with a failing
`claude --resume <id>` in every one of them.

Both spawn paths now pass the workspace id, and restore treats an owner
that parses as no workspace as no claim at all, so panes already stamped
by an older CLI attach instead of stranding.

* fix(cli): let the OWNER column speak only when it disagrees with WS

Now that a pane's owner is the id of the workspace holding it, printing
both spells the same id twice on every row of `pane ls --all` — and
buries the rows that matter. The column now shows a dash when the two
agree, so what is left is exactly what is worth reading: a pane its
holder may not attach to, and an orphan still naming where it belongs.
