av d48a18ae75 Ask the session what is running instead of counting it 
A session whose main agent had stopped while a background subagent worked
showed as waiting. The count was kept by hand -- +1 on PreToolUse matched
to ^(Agent|Task)$, -1 on SubagentStop -- and the two halves do not see the
same thing. A launch reaches the hook only at the top level: a subagent
spawning its own subagents does it through events carrying agent_id, which
are dropped. SubagentStop arrives for every subagent at every depth. Each
nested one subtracted from a batch it had never joined.

Measured on the live session that showed it: one background agent, then
fourteen nested stops, the first of which took the count to zero and turned
the chip white with the batch still running. Replaying those recorded
events through the old hook reproduces it exactly, and through the new one
holds busy throughout, rising to two while two background agents ran.

The events carry the answer themselves. Stop and SubagentStop -- the two
that can end a turn, and the only two where it matters -- come with
background_tasks: every running task with its type and status. The count is
now read from there and nothing accumulates, so it cannot drift, and a
subagent that dies without sending SubagentStop no longer leaks a count
that pins the chip at busy. Events without the field leave the stored value
alone, which is what keeps an idle_prompt nudge from freeing a working
session.

A background shell is deliberately not counted. A dev server left running
says nothing about whether the session needs you, and treating it as work
would hold the chip at "working" for as long as it lives.

PreToolUse is no longer registered: counting was the only thing it was for.
It stays listed as a legacy event so that both install and uninstall sweep
it out of settings.json rather than leaving it there to spawn the hook on
every agent launch for nothing.

av f8e85d5703 Put the clock on the working chips, and on all of them 
The counter rode on the first chip, whichever state it happened to be in.
It now shows on every chip that is working and on no other: how long a
session has been at it is the thing that decides whether to wait for it,
where the age of an idle one only says how long ago you stopped looking.

The setting keeps its key and changes its name to "Show working time".

CLAUDE.md is new, and its first rule is the one broken twice: writing to
dconf from a shell attached to the live session bus wipes settings that
cannot be recovered.

av be69bec17f Make the panel position and the label width settings 
Two things that were constants and had no business being constants.

Placement: the box (left, centre, right) and the index within it. The
default is unchanged -- centre, index 1, immediately right of the clock --
and an index past the end of a box lands at the end, so a large one means
"last". Applied at once, no reload.

Moving is done by rebuilding the indicator rather than by moving the actor.
addToStatusArea is what registers it under the uuid and there is no
documented call to move one between boxes; everything else reaches into
Main.panel's private boxes. It costs one re-read of a few small state files
and only when the setting is touched.

Label width: three characters by default, settable up to ten, not down.
Three is enough to keep initials apart and narrow enough not to shove the
clock about; below three, distinct projects start sharing a label. A wider
label takes more initials rather than a longer prefix -- a prefix collapses
dev-skills and dev-conventions at any width -- so dev-skills stays "ds"
however wide the setting, while claude-code-gnome-extension becomes "ccge"
at four. A disambiguating digit still eats into the label instead of
extending past the width, so a chip that gains one does not push the row.

Sticky labels work against that setting: kept labels are kept whatever
width they were cut at, so widening would leave every session on screen at
its old width until it ended. The width is therefore the one thing that
discards the map -- a relabelling that was asked for is not a label moving
under your hand.

The combo row is bound by hand: Gio.Settings.bind maps a boolean to
'active' and an int to 'value', but a string to a selected index needs
bind_with_mapping, which is not introspectable. Only the write direction is
wired up, and the test covers it, because a row that stores its index
instead of its value looks fine until the shell reads the key.

Fixed on the way, found by watching the centre box grow 2 -> 3 -> 4 -> 5
across four moves: PanelMenu.ButtonBox connects `this._onDestroy.bind(this)`
in its _init, and its _onDestroy is what destroys the container -- the
St.Bin the panel box actually holds. The name resolves through the
prototype chain, so this extension's own _onDestroy had been silently
replacing the shell's since the beginning, leaving an empty container in
the panel on every teardown. Renamed to _teardown; the box now stays at two
children across moves and across enable/disable cycles.

Verified in a nested shell on a copy of the extension carrying temporary
logging, since the shell refuses screenshots to non-portal callers: every
box, indices 0, 1 and 9, and widths 3, 5, 8, 10 and back, with no JS errors
and no leftover actors.

av 67d7b14cf5 Keep headless runs out of the panel 
`claude -p` was showing up as a session. It prints one answer and exits:
there is no input line, it cannot be blocked on you, and there is nowhere
to walk over to. A script that runs a few dozen of them turned the panel
into a flicker of chips that were gone before they could be read. The Agent
SDK and editor integrations drive claude the same way and are covered by
the same rule.

The flag is looked for in the arguments of the already-identified claude
process, by exact token, so nothing new has to be discovered -- the pid was
resolved on every event anyway. That resolution moved from apply_event up
into main, which is where the decision has to be made: a headless run is
dropped before the state file is touched at all, so it never creates one
and correspondingly never deletes one on SessionEnd. Its events still reach
the debug log, otherwise "why is my session missing from the panel" would
have nothing to answer with.

Arguments are now read by splitting /proc/<pid>/cmdline on its NUL
separators rather than on spaces. A prompt is an ordinary argument, and
`claude "when do I need -p"` is an interactive session that keeps its chip;
the old space-joined string could not tell the two apart. looks_like_claude
takes the list too, which is what it always wanted -- it was splitting the
joined string back apart itself.

Verified end to end as well as in the classifier: a fake claude runs the
hook as a child through /proc, with -p leaving no file and without -p
leaving one. A real `claude -p` against the installed hook added nothing to
the state directory.

av 2565d45bb5 Act on four reviews: state machine, resource bounds, teardown 
Four agents reviewed this in parallel -- correctness, GNOME integration,
edge cases, security. Everything below was reproduced before being fixed;
several findings that survived the first reading did not survive a probe
and are not here.

State machine, the two that mattered most. A pending permission prompt was
erased by any subagent bookkeeping event: SubagentStop or the next
PreToolUse recomputed the state from scratch, so a session sat at "working"
with a dialog open and nothing ever raised it again. Blocked now outlives
everything except evidence the question was answered. Separately, the
stale-event guard refused whole events, including the subagent counter's
increments and decrements -- but those are deltas and deltas commute, so a
"+1" that lost a timestamp race left the count short and the batch freed
the session while a subagent was still running. The guard now gates the
state decision only.

Corrupt or hostile state files could wedge the panel or take the hook down
for every session: a non-numeric pid raised inside sweep_dead before the
hook wrote its own file, so one bad byte stopped new sessions appearing at
all. Numbers read back from disk are coerced, one unreadable file no longer
aborts the sweep, and a stored timestamp far in the future -- corruption, or
a clock stepped backwards by NTP -- no longer refuses every later event
forever.

Resource bounds, all in the compositor process. A state file was read whole
with no size check: a symlink to /dev/zero took a test process past 4 GB in
three seconds, which in gnome-shell ends the session. Sizes are checked
before the read, sessions and zellij subprocesses are capped, labels
ellipsize, and cwd and messages are truncated at the hook.

Teardown hung off an overridden destroy(), which only runs when JS calls
it. An actor destroyed any other way -- another extension rebuilding the
panel boxes -- left the timer and the file monitor running against a
disposed actor. It is a destroy signal now. The zellij child is killed
rather than merely abandoned.

The glyph was pinned to physical pixels and rendered half-size on HiDPI;
size comes from the stylesheet, and the foreground colour is normalised by
inspection rather than assuming which colour struct the shell hands back.

Chip labels: non-Latin names all collapsed to "?", because the split
treated every Cyrillic letter as a separator -- notable for a tool whose
own README is Russian. Seniority also ranked by time-in-state rather than
session age, so after a shell restart the older session could take the
digit; the hook now records when the session began.

zellij: a dump ends with new_tab_template and swap_tiled_layout blocks
whose tab lines carry no name, and their panes were being attached to the
last real tab -- which then answered for every unmatched directory,
confidently and wrongly.

install.py no longer widens the mode of a settings.json someone narrowed to
0600, no longer overwrites the pristine .bak on a second run, no longer
replaces a symlink out of a dotfiles repository with a regular file, and
quotes the hook path. The debug log is capped and README now says plainly
that it records prompts verbatim.

Not fixed, deliberately: the panel does push the clock about 70 px left
with three labelled chips, which is inherent to putting them in the centre
box; two different projects abbreviating alike still read as one project
with a digit; GNOME 48 remains unverified for the colour struct and for
St.BoxLayout's vertical property, both flagged rather than guessed at.

av f4a06cdc44 Identify the claude process by argument, not by substring 
Testing the reboot case exposed a live regression, and the identity check
added for reboots is what made it visible.

Matching "claude" anywhere in an ancestor's command line was too loose. The
hook is spawned as `/bin/sh -c /.../claude-status-hook.py`, so its parent's
command line contains "claude" -- in the path to this very script -- while
being a shell that exits milliseconds later. That shell's pid was being
recorded as the session's. Existence checks alone hid it: the pid was dead,
the file was deleted, the next event recreated it, and the session flickered.
Once the pid was pinned to a process start time the session vanished
outright.

The rule was broadened in the first place to cover npm-style installs that
run `node .../claude-code/cli.js`, which was a real gap. It is now matched
per argument instead: argv[0] named claude, or a cli.js under a claude path.
Both installs pass, and the spawning shell does not.

The pid is also resolved before the unchanged-check rather than after, so a
pid that has changed forces a write. A session resumed under a new pid --
which is exactly what --resume does, and what this session had done -- kept
its old pid for as long as its state happened not to change, and the reader
would drop it as dead.

The debug log now records the process ancestry, which is what made this
diagnosable at all rather than guessable.
 2026-08-09 19:47:19 +03:00
av 75bfe77950 Survive a crash, and a reboot after one 
kill, a closed window, a reboot: no SessionEnd arrives and the state file
stays. Each case was tried rather than reasoned about, and one of the
three was broken.

A killed session was already handled -- the process is gone, so the file
and its lock are removed within the 20 s liveness tick. An interrupted
hook write left its temporary file behind forever; those are now swept
once they are five minutes old, which is late enough that a hook part-way
through writing one does not lose the update.

The reboot case was the broken one. State files outlive a reboot and pids
are handed out afresh, so "does /proc/<pid> exist" only answers "is some
process wearing that number". Verified by giving an unrelated live process
the pid of a dead session: the ghost sat in the panel as a session waiting
for input, and would have stayed there forever, asking for an answer
nobody could give. The pid is now pinned to the process start time from
/proc/<pid>/stat, recorded when the state is written and compared when it
is read.

Files written before that field existed compare only on existence, as
before, so a session open across the upgrade is not evicted.

An abandoned flock needed nothing: the kernel drops it when the holder
dies, so there is no deadlock to recover from.
 2026-08-09 19:43:31 +03:00
av ca42d69704 Cap the chips at three, and make the menu report-only 
Two changes that pull in the same direction: the panel says less, and the
menu stops pretending to do anything.

The chip row had no bound. It sits in the centre box next to the clock, so
enough open sessions would have shoved the clock off centre. It now shows
the first N, settable and three by default, and counts the rest as "+N".
Chips are already ordered by urgency, so the ones that survive the cut are
the ones that need you soonest. Labels are still assigned across every
session, including hidden ones, so a chip does not change when the cap
does or when a session ahead of it disappears.

Clicking a menu row used to switch the zellij tab and raise a terminal.
That is gone. It cost real machinery for what it saved -- gnome-terminal
runs every window under one shared server process, so windows cannot be
matched by pid and the code fell back to matching the zellij session name
against window titles, with all the ways that misses. The menu reports
status; alt-tab is not the bottleneck. Rows are built inert rather than
demoted after the fact, because PopupBaseMenuItem latches _activatable in
its constructor.

zellij tab lookup stays: naming the tab is the better half of that feature
and costs one process every couple of minutes.

The preferences test now asserts a control per settings key rather than a
switch per key, so the new spin row counts and a future non-boolean
setting cannot slip in without one.

# Работа над этим расширением
## Никогда не писать в dconf живой сессии
**Запрещено** выполнять `gsettings set`, `gsettings reset`, `dconf write` и `dconf reset`
из bash этой сессии — ни голыми, ни с префиксом `XDG_CONFIG_HOME=...`.
Почему префикс не помогает: базу выбирает не клиент, а `dconf-service`, поднятый шиной
живой сессии, и берёт он её из **своего** окружения. Любая запись уходит в
`~/.config/dconf/user` Антона.
Чем это кончалось (дважды): затёрт `org.gnome.shell enabled-extensions` — во второй раз,
9 и 10 августа 2026, на работающем shell, отчего у него мгновенно отвалились dock, ding,
appindicators и tiling-assistant. Прежний список dconf не хранит, восстановить его точно
нельзя, только реконструировать.
Что делать вместо:
- нужно поменять настройку в **живой** сессии — отдать Антону команду, он выполнит её сам
через `! <команда>`;
- нужна настройка для **вложенного** shell — экспортировать `XDG_CONFIG_HOME` до форка
шины и звать `gsettings` уже внутри этой шины (см. рецепт ниже);
- читать (`dconf read`, `gsettings get`) можно свободно.
## Проверка изменений — только во вложенном shell
Живую сессию не трогаем вообще: расширение включает и перезагружает shell Антон сам.
У него несколько сессий Claude Code в zellij внутри gnome-terminal, и падение
gnome-shell унесёт весь его рабочий набор.
Рецепт для проверок только на чтение (GNOME 46, проверен 10.08.2026):
```sh
XDG_STATE_HOME=$TMP/state timeout 50 dbus-run-session -- \
gnome-shell --nested --wayland > $TMP/nested.log 2>&1
```
Подставные файлы сессий обязаны нести `event_ts` (плюс `since`, `started`): без него
`SessionStore` считает их древними и **удаляет** до первой отрисовки.
Скриншот из вложенного shell снять нельзя. Чтобы увидеть, что он нарисовал, добавляем
временный `log()` в код, читаем его из `nested.log` — и убираем инструментацию перед
коммитом.

Бокс (левый, центральный, правый) и позиция внутри бокса задаются в настройках и
применяются сразу, без релогина. Индекс 0 — первым в боксе; в центральном 1 —
сразу справа от часов, единственного его обитателя по умолчанию. Индекс больше
числа элементов кладёт ряд в конец, так что «10» — это способ сказать «последним».
Перестановка **пересоздаёт** индикатор, а не двигает актор: `addToStatusArea` —
это и есть регистрация под uuid, а публичного вызова «перенести в другой бокс» в
shell нет; всё остальное лезет в приватные боксы `Main.panel`. Стоит это одного
перечитывания нескольких маленьких файлов состояния, и только когда настройку
трогают.
Здесь же вскрылась давняя утечка. `PanelMenu.ButtonBox` в своём `_init` делает
`this.connect('destroy', this._onDestroy.bind(this))`, а его `_onDestroy`
уничтожает `container` — тот самый `St.Bin`, который лежит в боксе панели.
Имя разрешается по цепочке прототипов, поэтому наш метод с тем же именем **молча
подменял** шелловский, и контейнер оставался в панели после каждого выключения
расширения. Наш обработчик теперь называется `_teardown`. Измерено: до
переименования центральный бокс рос на один пустой актор с каждой перестановкой
(2 → 3 → 4 → 5), после — стабильно 2.

же причине не течёт, если сабагент умрёт, не прислав `SubagentStop`.

## Аварийное завершение
`kill`, закрытое окно, перезагрузка — `SessionEnd` не приходит, и файл остаётся.
Разбор завалов проверен на каждом случае отдельно:
| Что осталось | Что с этим происходит |
|---|---|
| файл убитой сессии | процесса нет — файл и его `.lock` удаляются в пределах 20 с |
| файл из прошлой загрузки | pid сверяется по времени старта процесса, а не только по наличию |
| оборванная запись хука (`.tmp`) | удаляется, когда старше пяти минут |
| незакрытый `flock` | ядро снимает блокировку при смерти процесса — тупика не бывает |
Сверка по времени старта — не перестраховка. Файлы состояния переживают
перезагрузку, а pid после неё раздаются заново: проверка «есть ли `/proc/<pid>`»
отвечает лишь «какой-то процесс с таким номером есть». Без этой сверки сессия,
погибшая в аварии, висела бы в панели вечно, требуя ответа, которого некому дать.
Проверено подстановкой постороннего живого процесса на тот же pid.
Порог в пять минут для `.tmp` тоже осмысленный: хук может писать такой файл
прямо сейчас, и удаление свежего стоило бы потерянной записи.
Опознание самого процесса claude — отдельная тонкость. Хук запускается как
`/bin/sh -c /…/claude-status-hook.py`, поэтому в командной строке его родителя
слово «claude» **есть**, а сам он — не claude и живёт миллисекунды. Поэтому
совпадение ищется по отдельным аргументам (`argv[0]` называется `claude`, либо
`cli.js` внутри пути с `claude`), а не по строке целиком. Если опознать не
удалось, пишется pid 0.
Найденный pid сверяется на **каждом** событии, а не только при записи: сессия,
поднятая через `--resume`, получает новый pid, и без этой сверки файл сохранял бы
старый до ближайшей смены состояния — а читатель, не найдя того процесса, убрал бы
живую сессию из панели.
Если хук вообще не смог опознать процесс claude, он пишет pid 0 — «неизвестно»,
что никогда не путается с «мёртв»; такие записи истекают по возрасту, через
36 часов.
## Известные шероховатости ## Известные шероховатости
- **Протухшие сессии.** Убитый терминал не присылает `SessionEnd`. Живость
перепроверяется каждые 20 с по `/proc/<pid>`, файл удаляется — убитая сессия
исчезает в пределах этого окна, а не висит вечно. Если хук вообще не смог
опознать процесс claude, он записывает pid 0 — «неизвестно», что никогда не
путается с «мёртв», — и такие записи истекают по возрасту, через 36 часов.
- **`Stop` не отличает «закончил» от «сдался».** Оба читаются как «ждёт ввода», - **`Stop` не отличает «закончил» от «сдался».** Оба читаются как «ждёт ввода»,
и решение для вас в обоих случаях одно и то же. и решение для вас в обоих случаях одно и то же.
- **Фокус ведёт к табу zellij, а не к окну.** gnome-terminal держит все окна под
одним общим серверным процессом, так что окно нельзя сопоставить по pid. Окно
поднимается, только если в его заголовке есть имя zellij-сессии; когда
совпадения нет, таб всё равно переключается, а фокус остаётся на месте —
поднять произвольный терминал хуже, чем не поднимать никакой.
