irisandClaude Opus 5 1d843f20f2 Let the driver say it started, so both screens agree
The session list reads the manager's status; the session screen replays the
transcript. Correcting a relaunched session's stale `exited` by writing the
manager's view directly left those two saying different things about one
session -- which showed up as a stop button that turned into a play button a
moment after the screen opened, and a status row that disagreed with the row
it was opened from.

So the correction goes through the event sink instead, from the driver that
started the process: `EchoDriver::new` and `LlamaDriver::attached` already
announce the state they start in, and `ClaudeDriver` was the one starting a
process silently. It says idle only when it started one -- adopting says
nothing, since a process that was already running may be mid-turn. Coming
from the driver also orders it against the exit `follow` reports for a
process that dies immediately, which a status written from the manager could
not be.

Verified against a stand-in CLI: stop, restart the backend, and the list and
the transcript's last status both say idle, with the relaunch recorded.

irisandClaude Opus 5 6154cb1949 Stop and start a session's process from the composer
The composer's second button now says what pressing it would do to the
process behind the session, in one place that is always there: an orange
pause while a turn is running (interrupt, the process stays), a red stop
when it is not (end the process), a green play when it has exited (start it
again on the same conversation). Send is disabled while there is nothing to
send, rather than pressable and silent.

Behind it, two routes. `stop` signals the recorded process and says nothing
else -- the driver's own reader already reports a death correctly, and
announcing it here would be a guess ahead of the measurement. `start`
replaces the driver and nothing else, so the transcript, the pump and every
open phone's stream stay where they were and there is still one writer of
the transcript; it is refused unless the session is known to have exited,
since starting on `Unknown` is the two-CLIs-on-one-conversation fault.

That last rule found a bug in the launch path: a relaunched session took its
status from the transcript, so one whose process had died before a backend
restart reported `exited` while the launch had just started a new process --
which refuses every command and offers a phone the chance to start a second
CLI on a live conversation. A launch that leaves a process running now says
idle.

The icon font moves to the Mono face, where every glyph is one em square, so
two icon buttons are the same width without either being told one; the
proportional advances ran 0.46 to 0.92 em and Send came out visibly wider
than Stop. GLYPH_SIZE comes down to match, since a glyph that fills its em
draws bigger at the same point size.

Verified against a stand-in CLI on the emulator: idle -> stop -> exited ->
start -> idle, a turn interrupted from the pause button, and both buttons
measured at 171x105 device pixels.

iris 0d623b7073 Recover a session's context from the CLI's own file
A restarted server has been told nothing, so a Claude session that has not
taken a turn since reported its context as unknown -- which was true, and
useless, since the CLI had written the figure down at the time and it was
sitting in the session's file the whole while.

It now reads it from there at load, over the session's transport, in the
background: the same three input fields the import list already reads, so
it is a measurement rather than a guess. Only when nothing else has
answered, and only for a provider that keeps such a file.

A clear needs no special case even though it makes the last usage in a
file stale, because clearing gives the CLI a new session id -- so the
lookup lands on a file with no usage yet and answers unknown, which is
what it is.

iris bc0a48799c Put a question to the reader on a row of its own
An AskUserQuestion arrived in the middle of a run of tool calls and was
folded into the collapsed card with them, so the one row where somebody
was asked something -- and the answer they gave -- was hidden behind
"Called 6 tools" like any other grep.

It now starts a run of its own and ends the one before it, which needs no
change to the grouping: a run of one is drawn as itself. The calls around
it become a group before and a group after, so where the work stopped to
ask is legible from the shape of the transcript without opening anything.

Echo's `/ask` now runs three ordinary calls on each side of the question,
because that is the shape this has to be looked at in and there was no
way to produce it.

iris 5e11b9da80 Report the context a session holds, not what it has spent
The number on the status row was a running total of tokens spent, so it
could only ever climb: a session compacted from 128k down to 10k, or
cleared outright, went on reporting the larger figure, and disagreed with
the divider directly above it saying what the compaction had recovered.

It now reports what the model is holding -- prompt plus both cache
figures -- folded through `driver::context_after`, which is the one rule
the pump, the transcript and the phone all use: a turn sets it, a
compaction replaces it with what the compaction measured, and a clear
leaves it unmeasured. Unmeasured says so in words, because an empty
context and one nobody has counted used to look identical.

Taken from the turn's last assistant message rather than its `result`:
measured against CLI 2.1.237, a two-message turn reported a cache read of
40,211, being 14,259 and 25,952 -- the same conversation counted twice,
and no size the model ever held.

iris 68704fce7c Ask the driver whether a command can go, not the status it reported
A `/clear` that did nothing, traced to the end. There was no race to lose:
the driver sees every line it writes and every line that comes back, so it
always knew. What it knew was being asked of the wrong thing.

Two views of "is a turn running" had grown apart. The driver's moves the
instant it writes a line; `SessionStatus` moves when output is *recorded*.
Messages ask the driver -- which is why they behave -- and commands asked
the status, which for a command is stale for its whole round trip: a
command's reply carries no assistant text, so nothing proved a turn had
started and the recorded status stayed idle from the moment it went out
until the moment it came back. A second command in that window went
straight out too, landing inside the turn the first one had started, where
the CLI reads it as text instead of running it. Nothing anywhere says so:
a command read as a message looks like a message.

So `Commands` asks `Driver::between_turns()` now, and asks again when it
releases a held one -- the recorded idle that woke it is a moment in the
past by then. `local_command` says `Running` when it writes, which is both
true and what makes the next idle a change worth recording; without it the
idle at the end of a command was equal to the idle before it, and nothing
behind it was ever released.

The other half was a turn nobody here started. The CLI picks the
conversation back up on its own -- measured: a backgrounded `sleep`
finished nine seconds after the turn's result and it began again unprompted
-- and it announces that with a `system/init` about a second and a half
before its first assistant text. We had been ignoring that line and
learning about the turn from the text, so for that second and a half the
session read as idle. It is a turn now, told apart from the `init` at
startup by the translator already having a session id, and from our own
`/clear` by `running` already being true.

Measured against the real CLI, not argued: two `/clear`s sent back to back
on one connection now record `commandSent`, `running`, `commandQueued`,
`cleared`, `idle`, `commandSent`, `cleared` -- held, then run, in order,
both of them. Before this the second was swallowed. The self-started turn
shows as `running` eleven seconds after the previous turn's idle, which is
the window a command used to disappear into.

Also measured on the way, and worth writing down: a message written into a
running turn is *folded into it* -- one `result`, `num_turns: 2`, both
things answered -- so an idle after one is honest and there was nothing to
fix there. A command written when the CLI is genuinely between turns is
executed even ten milliseconds after the result, so the boundary itself was
never the problem.

iris f1a185a9cd Answer a command a session can never run, and put attachments under the text
Investigating a `/clear` that did nothing. What I could measure says the
basic path is sound: the CLI honours `/clear` in stream-json mode -- it
emits `conversation_reset`, opens a fresh session id, and the model then
answers "NO CONTEXT" to a question about something it was told a moment
before -- and a `/clear` sent into a running turn is queued here and applied
at the boundary, with the model losing context, in two reproductions.

What the investigation did find is a command that can wait forever. Held
commands drain at the next idle, and a session whose process is gone has no
next idle, so `/clear` sent to one sat in the queue with a waiting bubble on
the phone that nothing could resolve and nothing anywhere saying why. The
*message* path has always answered this case -- a message to the same
session reports the exit at once -- which is what made the silence visible:
one session answered one and swallowed the other. A command owes the same
answer, since what makes it unanswerable is the same fact.

`Unknown` still waits. It means nobody could find out whether the process is
there and it resolves itself, so refusing on it would turn "we don't know"
into "it's gone".

`local_command` gets the `closed` check `send_user_message` has had all
along, for the window between the status being read and the line being
written -- a line into a fifo nothing is reading goes nowhere and looks
exactly like one that arrived.

Attachments now draw under the message text rather than above it: what
somebody wrote is what the bubble is, and it keeps the first line of every
bubble in the same place down the transcript whether or not there is an
image in it.

iris b0629f77ca Shrink a photo to what the provider takes, and put it in its own bubble
Sending an image was broken in the way that is hardest to see from the
phone: a camera photo is twelve megapixels and several megabytes, the Claude
API resizes anything past 1568px on its long edge before looking at it and
refuses far larger outright, so the picture was uploaded whole over the
tunnel to be thrown away or rejected at the other end.

Shrunk on the phone, to a limit the server states. Which number it is comes
from the provider's *kind* -- `DriverKind::max_image_edge`, reported on the
session row -- because that is where a provider's requirements are known,
and a phone carrying its own copy of them would be a second place to update
when one changes. `None` where nothing cares, rather than a large number:
"no limit" and "a limit that happens to be big" are different answers and
only one of them stays true. Doing it before the upload rather than after is
the point -- the expensive part on a phone is the tunnel, not the decode --
and an image already inside the limit is uploaded byte for byte rather than
being round-tripped through JPEG for nothing.

EXIF orientation is applied while scaling. The camera writes which way up
the picture is into a tag rather than into the pixels, and re-encoding drops
it, so a portrait photo would have arrived at the model on its side with
nothing anywhere saying so.

**What is attached is now visible before it is sent**, in a row directly
above the box it will be sent from: the count on the "+" button said how
many and never which, so the only way to find out what you had picked was to
send it. It scrolls sideways rather than shrinking, and tapping one takes it
back off -- an image picked by mistake could otherwise only be dealt with by
sending it. The tile is outlined as well as filled, because most of what
gets attached here is a screenshot of a dark app and a cropped one is
near-black: without an edge the only thing on screen saying an image was
attached was the cross drawn on top of nothing.

**And the picture is inside the bubble that sent it.** Attachments used to
be their own `Image` events emitted just before the message, which drew
somebody's screenshot as a row floating above the bubble and left the phone
deciding from adjacency alone which message an image belonged to -- a thing
the sender knew and could simply say. `UserMessage`, `MessageQueued` and
`MessageTaken` carry the refs now, so a waiting message keeps its picture
for as long as the turn runs, and a replay puts it back in the same place.

Verified on a real claude-cli session rather than an echo one, since the
limit only exists for that kind: a 3000x4000 image arrived as 1176x1568
JPEG -- long edge exactly the limit, aspect ratio intact -- and haiku
answered "AI Sessions displays idle Photo", which is what the picture was.
No error, and the transcript records the message with `images` on it.

iris de049bcec6 Hold the transcript still while somebody is reading further back
Two separate defects, both of which moved the list under the reader.

The first: a row that grows drags the view toward the newest end. The
list is laid out from the bottom, so it anchors on the first visible
item's *bottom* edge -- and a reply streaming in extends that row
upwards, pushing everything already on screen with it. Measured against
a reply streamed in four hundred pieces: scrolling back one screen and
waiting six seconds ended at the very bottom, forty lines further on
than where it was left. So the transcript now only changes while the
reader is at the newest end; anything arriving before then waits in
order and lands when they return. Status, tokens and the model still
update live, because none of those are drawn in the list and freezing
them would trade a jumping transcript for a status row that lies.

The second: every markdown row was measured at nothing before it was
measured at its real height. The renderer's `content: String` overload
parses in a coroutine and draws an empty loading slot until it finishes,
so a row composes with no height and springs open a frame later. Seen
with five replies on screen at once, all blank, the whole conversation
shrunk to a single screen. Parsing in the composition costs a few
milliseconds on the main thread and is worth it: no scroll anchoring can
survive a row that lies about its height first.

`/stream N` in the echo driver is what made the first one reproducible
-- `/slow` emits a line a second, and the growth has to be continuous
for the anchor row to drag.

Verified on the emulator: scrolled back through a whole 400-piece
stream, the transcript region is pixel-identical across ten seconds
while the status row goes from working to idle; returning to the bottom
brings the backlog in one go. Checked the tool-call rig too, which this
change had no reason to touch -- paging back still works and every group
still reads "Called 8 tools".

iris 47d6b84265 Report what a session last did and what it cost, not what this page holds
Three readings that were each a part presented as the whole.

**"just now", everywhere, after a restart.** A relaunched session took its
last-activity from the clock, so every session the backend brought back
claimed to have been active that instant. On the phone that is every row
reading "just now" and the list -- which sorts by it -- coming back in an
order that means nothing, with the conversation somebody was in the middle
of buried among sessions untouched for days. It comes from the transcript
now, in the pass `Transcript::open` already makes, which is the same
correction `last_status` got and for the same reason: a server that has just
started has been told nothing, and the file is the only thing it knows. The
test backdates a transcript by a day, so it cannot pass by the test being
fast; it fails on the old code with the clock's answer in the message.

**The token total was the newest page's.** The phone added up the
`UsageDelta`s it had received, and it opens a session on the newest page of
the transcript -- so a long conversation reported its last few turns as the
total, and a page with no turn in it reported nothing at all, since zero is
drawn as blank. That is the reading Bryan saw: no tokens, on sessions that
had certainly spent some.

The count belongs to the server, which is the only side that sees every
turn. `UsageDelta` now carries the running total beside the delta, filled in
by the pump rather than by each driver -- a driver knows what its own turn
cost and nothing else does, so a new one cannot get this wrong by leaving it
out -- and the session row reports it for a screen that has not opened the
stream yet. The phone takes the largest total it has seen instead of
accumulating, which also means paging older history cannot move it, and
leaves the seeded figure alone for transcripts recorded before the field
existed. Seeded by summing deltas at startup for exactly that reason.

**The header said the model twice and the machine backwards.** A session's
subtitle now reads `machine · provider`, in that order and with no "on"
joining them, matching the list and the usage dialog -- the "on" made it a
phrase, which works in one order and stops working the moment the same pair
is shown somewhere else. The model is gone from it: the footer's picker
already shows what the session is set to, and two places showing it meant
two things to keep in step, which disagreed for a moment on every switch
since one follows the request and the other the session's own answer.

Checked on the emulator against a twelve-turn session whose visible page
held the last six: the header reads "this machine · echo", the status row
reads "idle", and the total reads 42 tok, which is what `GET
/sessions/{id}` says rather than what the page adds up to.

iris 135950c8ed Say when a session wants you, and stop calling a stop an error
Three things Bryan asked for, and one the second of them exposed.

**Notifications.** A session that asks a question or finishes a turn now
says so on the phone, per session, switchable from its settings screen.

The switch is stored on the backend rather than the phone, because it is a
fact about the session: one that runs unattended overnight should be quiet
on every device, and answering that question again on each device is how two
of them come to disagree. It is on by default -- a notification nobody
wanted is turned off in one tap, where one that never arrived is not
diagnosable at all.

Which moments count is `notification_for`, and the asymmetry in it is the
point. *Waiting on a person* is worth saying however it was reached.
*Finished* is only worth saying when this server watched the work happen:
sessions settle into idle for several reasons that are not "your work
ended", including every one of them being adopted at startup, and announcing
those would put "finished" on the phone for the whole config on every
backend restart. That is the failure that makes somebody switch the feature
off, so it has a test naming every transition rather than the two that
work.

The stream is `GET /notifications`, live only and with no cursor -- the one
place this server does not offer to catch a client up. A notification is a
claim about now; replaying "your turn" from an hour ago sends somebody to a
session that may have been answered from another device since, and a
notification that is wrong costs the trip *and* the credibility of the next
one. What was missed is still on the session list, which says what is
waiting without claiming to be news.

On the phone it is a foreground service, because Android has had no
long-lived background service since 8.0 -- it is what Syncthing does, and
Discord is not a counter-example since it takes a push from Google, which
would mean this backend talking to Google about somebody's sessions. The
ongoing notification Android charges for it sits on an `IMPORTANCE_MIN`
channel: no sound, no status-bar icon, bottom of the shade. `specialUse`
rather than `dataSync`, which is what it looks like: Android 15 caps
dataSync at six hours a day, and a connection that stops listening after six
hours misses the overnight run it exists for.

**A stop is not an error.** The CLI reports an interrupted turn exactly as
it reports a broken one -- `is_error` on a `result` -- so pressing Stop
showed "the turn ended with an error" for doing what the button says. The
line cannot distinguish them; what does is that this side asked, so the
driver says so before the request goes out and the translator spends that on
the next result. The test's second half is the one that matters: the naive
fix passes the first half and silences every genuine failure after it.

**Every status says which one it is.** The session screen's status row named
only `exited` and left the rest blank, so idle and "nobody could read it"
looked identical -- and a just-stopped turn showed nothing, which reads as
the app having lost the session rather than as the stop having worked. The
words are the session list's own, so a state is not called two things
depending which screen you are on. Red on a quota bar now starts at 90%.

**`GET /sessions/{id}`**, which the notification switch found missing. A
screen opened from a list row carries the row the list last fetched: fine
for a title, wrong for a switch, which is *set to* something. Caught on the
emulator, where the switch read on against a backend that said off, with
nothing on screen to say which was true. The screen now reads the session
when it opens, and until that answers the switch is disabled and says so --
a two-position control cannot say "I do not know", so it does not pretend
to.

Verified on the emulator with the app backgrounded: the service holds the
stream (`isForeground=true types=0x40000000`), a finished turn posts
"Finished" and a question replaces it with "Waiting for you" on the same
tag, turning the switch off silences it with no restart, and turning it back
on from the phone reaches config.ron. The interrupt is a translator test
rather than a live turn, which is where that logic is anyway.

iris 2dc61c5780 Stop drawing one tool call twice where a page of history begins
A page boundary lands wherever it lands, and about half the time that is
between a tool call and its result. The newer page then holds a `ToolEnd`
whose start it never saw, which the fold draws as a row of its own --
correctly, since a call rendering as nothing is indistinguishable from
one that never happened. But when the older page arrived it brought the
real `ToolStart`, and the two lists were concatenated, so the call was
left on screen twice: once as a proper card and once as a nameless
placeholder.

`joinPages` merges the two halves by the call's own id instead, which is
the one thing a page boundary cannot destroy. The older half wins on what
a start knows -- the tool's name, its input -- and the newer on what an
end knows, its output and whether it finished.

The miscount was the visible part; the moving was the point. The extra
row sits exactly at the join, which is where the reader is looking when
the page loads, so everything below it stepped down by a row at the
moment they scrolled into it.

Demonstrated both ways round on a rig of twelve `/tools 8` runs, whose
groups are eight calls each and whose page boundary falls inside the
second one: without this the transcript reads "Called 9 tools" there and
eight everywhere else, with it every group reads eight.

That rig is `/mixed N` in the echo driver, added here: N beats of
paragraphs at three lengths, single tool calls, runs of adjacent ones,
images and peer messages -- every row shape the app draws, in one
session, from a command that costs nothing and produces the same
transcript every time. The paragraphs are deliberately ragged, because a
wall of identical lines looks the same at every offset and makes a scroll
of one line indistinguishable from a scroll of ten, by eye or by
comparing frames.

iris e37e90a579 Let the server say what is waiting, instead of the phone remembering
A message sent into a running turn was drawn as a pending bubble from
screen state, so leaving the session or restarting the app showed nothing
waiting while the queue was full. Nothing waiting is what "there is
nothing" looks like -- the reader had no way to tell it from a queue that
had already drained, and Bryan hit exactly that: a message he sent
arrived, and his phone stopped showing it after a restart.

The server now records the waiting. `MessageQueued { id, text }` goes into
the transcript when a driver takes a message it cannot deliver yet, and
is resolved by the `UserMessage` carrying the same id -- the same shape
`CommandQueued` and `CommandSent` already had, so this is one more
instance of a mechanism rather than a second one beside it.

The message itself still lands where the session read it, which is what
the last change was about; only the *waiting* is recorded early. The two
are different facts and now have different events.

Paired by id rather than by text. The old code removed the bubble whose
text matched, so sending the same thing twice cleared the wrong one and
left a message on screen that had already been read.

Both drivers that can queue do it: the echo driver too, because the phone
now draws pending bubbles from the stream and a rig that skipped the
event would exercise a state the real app never sees.

Checked on the emulator: two messages sent into a `/slow` turn, then the
app force-stopped and relaunched -- both still drawn as waiting, in the
pending style, and both resolved into ordinary bubbles when the turn
ended and the session read them.

Still outstanding, and worth knowing: an entry outlives a *server*
restart in the transcript but not in the driver's memory, so a backend
restarted mid-queue would leave the bubble drawn with nothing coming to
resolve it. Before this change that message vanished from the transcript
entirely, so the failure is now visible rather than silent -- but it is
not yet right.

iris 76ba24993c Make the permission mode the picker offers actually selectable
The session screen's mode picker listed `bypassPermissions`, and on any
session not born in it, choosing it failed:

    Cannot set permission mode to bypassPermissions because the session
    was not launched with --dangerously-skip-permissions

The CLI is asymmetric about that mode and it is not obvious. It will
launch straight into it on `--permission-mode` alone -- so spawning into
it from the phone has always worked -- but it refuses to switch into it
afterwards unless the process was started with the flag. So the picker
offered a state the session could not reach, and the failure arrived
after the fact as an error line in the transcript.

Sessions now launch with `--allow-dangerously-skip-permissions`, which
makes that mode reachable without selecting it: the session still starts
in whatever mode it was asked for and only moves when somebody moves it.
Deliberately the `--allow-` form; `--dangerously-skip-permissions` is the
one that turns bypassing on for everything, which would take the choice
away from whoever is holding the phone. Since the mode was already
reachable at spawn, this withholds nothing new -- it makes the two routes
to it agree.

Measured both ways round against 2.1.237, driving the control request
directly: without the flag the response is `subtype: error` with the
message above, with it `subtype: success, mode: bypassPermissions`. Then
through the app's own route on a session spawned `manual`, whose argv
reads `--permission-mode manual … --allow-dangerously-skip-permissions`
and which reported `permissionMode: bypassPermissions` when asked to
change.

iris 549e49bc10 Record a steer where the model read it, not where it was typed
A message sent while an answer was streaming was recorded in the middle
of that answer and above the tool call it ended with. The model had
committed to that call in the same message it was already writing, so it
had read none of it -- and on screen the tool result underneath read as
something the steer had asked for. The answer also split into two
bubbles around a message that was not part of it.

The driver announced a steer at "the next assistant text or tool call",
on the reasoning that anything the CLI says next is proof it has been
round the model again. With --include-partial-messages that is not true:
the deltas and the tool_use block of a message already in flight keep
arriving afterwards, and none of them saw the steer.

`message_start` is what actually proves it. The CLI sends the previous
call's tool results back before it opens the next assistant message, so
that line is the first moment anything written since can have been read
-- and it carries no events of its own, which is what makes it a place
to put one. Verified against 2.1.237: message_start, the blocks, the
tool_result, then the next message_start.

The end of the turn stays as the other half, and is the case that must
not be lost: a message typed after the final model call has no later
message_start, and one that is only recorded when announced would
otherwise vanish while a phone drew it as still waiting.

Checked live on haiku, before and after. Before: the steer landed at
seq 37 among the essay's deltas, with the tool call at 45 and its result
at 46. After: essay whole, tool call 42, result 43, steer 44. Also
checked the case this had no reason to touch -- a steer sent during a
30-second Bash call, which was already correct -- and it still records
after the result. The two tests fail on the old rule; the failure prints
the old order, which is the bug.

irisandClaude Opus 5 894180de77 Take the CLI's word for a clear instead of inferring it
Bryan reported no divider when clearing. It was not this code -- the
backend serving him started at 17:06, three hours before `Event::Cleared`
existed, so it has no such event to send and `/clear` reaches it as an
unrecognised passthrough. Verified against a current build: the event is
recorded.

Probing the CLI to establish that turned up something better than what
was here. `/clear` in stream-json mode emits a dedicated
`conversation_reset` line and *then* a fresh `init` with the new session
id -- so watching the id be replaced, which is what this did, was reading
the event through one of its side effects. The announcement says it
directly, and it arrives first, so the divider now lands above the new
conversation rather than after its opening line.

That also removes the reasoning the previous commit needed about which id
changes count. There is one signal now instead of an inference with two
exceptions, and the test that used to pin those exceptions became
`an_init_alone_is_never_a_clear`, which covers all three ways an init
arrives: a session's first, the one a compaction re-announces with the
same id, and the one following a resume.

The resume token still follows the id, unchanged -- one CLI event with
two observable effects, and each half now reads the half it needs.

Verified end to end against a real claude-cli session: message, /clear,
message, and the transcript reads userMessage / assistantText / cleared /
userMessage, in that order. 74 tests, clippy and rustfmt clean.

irisandClaude Opus 5 71067275e2 Stop claiming a terminal, and stop calling a recoverable delete final
Two bugs Bryan hit, with one shape between them: a claim stronger than
the thing that was measured.

**The delete warning branched on `imported`.** It told him deleting
`ai-app` could be undone and deleting `manager` could not, when both are
claude-cli sessions whose conversations survive equally. `imported`
records how a session got into the app; what decides recoverability is
whether the *driver* keeps its own record -- the Claude Code CLI does,
under ~/.claude/projects, however the session started; echo and llama.cpp
do not, and for those the app's transcript is the only copy. So the fact
now sits on DriverKind and rides on SessionInfo, decided by the server
from the provider's kind rather than by the phone from its name, which a
person can change.

The comment above the branch asserted "a session started here has no copy
anywhere". That sentence was the bug written down and reasoned from, and
it is gone.

Neither branch promises a restore, which it should not: nothing here
checks the file is still on disk, and re-importing was never a restore
anyway -- this app's transcript holds images, peer messages and command
events the CLI's record never had. So the recoverable text says what is
known and names what goes either way. "Can't be undone" is now said only
where it is true, which is the point of saying it at all.

**"open in a terminal -- close it there first" named a place that need
not exist.** The detection is right and worth keeping: something live
holds that session, and importing it would reproduce the double-resume
incident. But which something was never measured. The live descriptors
here include two of this backend's own adopted sessions and a peer
agent's; none is a terminal, so the instruction sent the reader looking
for a window that was not there.

**And this app did not recognise its own spawned sessions.** The import
list filters out what the app is already driving, but it matched only the
import cursor -- which exists solely for imported sessions. Every session
the app spawned therefore stayed in the list, marked in use, telling the
reader to go and close it somewhere: here. Matching the resume token too,
which both kinds have, is the fix; `session_importing` is now
`session_driving`, because that is what it was always being asked.

Verified on the emulator against a scratch backend: a spawned claude-cli
session reports keepsOwnTranscript true with imported false -- Bryan's
`manager` case exactly -- and draws the recoverable warning; the echo
session draws "can't be undone"; and once the CLI named itself, the
spawned session's id was absent from the import list, where the old match
would have listed it.

irisandClaude Opus 5 5f6fd34aba Record the clear that happened, not the one that was asked for
`ClaudeDriver::clear` emitted `Event::Cleared` beside the `/clear` it
sent, so the divider recorded a request. A reader scrolling back takes
that mark as a fact about the conversation -- the session no longer has
what is above this -- and a request is a different claim from a result.
Compaction already gets this right by taking its mark from the CLI's own
`compact_boundary` rather than from somebody pressing Compact; this is
the same rule, and it was the one place left applying it to the request.

Caught in review by the session this was measured against, which also
established that the CLI's `/clear` is declared `supportsNonInteractive`
and returns empty text with no result line -- so a fresh `init` bearing
a different `session_id` is the only trace it leaves. The reader already
watches for exactly that in order to persist the resume token, so the
mark now goes out there.

It has to be a *replacement* rather than any change, and the tests pin
both ways of getting that wrong. The first `init` sets the id from
nothing, which would otherwise open every session with a divider
announcing a clear that never happened. And a compaction re-announces
`init` carrying the *same* id, which would otherwise draw a clear on top
of the compaction's own mark -- that one was found by writing the test
rather than by reasoning about the change.

irisandClaude Opus 5 6680fbb987 Clear from the phone, and put the numbers where they are read
Four changes to the session screen, three of them Bryan's and one that
fell out of them.

**/clear is offered like any other session command.** It joins
SESSION_COMMANDS, so it suggests itself while being typed and goes out
through the command endpoint that /compact already uses -- no new path,
and the boundary pump holds it mid-turn exactly as it holds a compaction.

**A clear draws a divider, not a deletion.** `Event::Cleared` becomes a
ClearedNote row saying that everything above stays here and is no longer
sent. That sentence is the row's whole job: the reader can see the
conversation is still on screen, so without it the divider reads as
something having been thrown away, which is the one thing it is not. It
carries no counts, because nothing was measured -- a compaction's
numbers are real and there is no equivalent here to report.

Compaction and clear now share `TranscriptDivider`. They are the same
kind of mark to somebody scrolling back -- "the session no longer has
what is above this" -- and the difference belongs in the words rather
than in how they are drawn, so the styling is written once and cannot
drift.

**The five-hour usage bar sits under the session header.** It reports
the paid service's own metering for the machine this session runs on,
fetched from that machine, refreshed every minute off the backend's
cache. It is never derived from the transcript's token counts: those are
a different quantity measured differently, and a quota-shaped bar built
out of them would be a guess wearing a measurement's clothes. Not
knowing has its own appearance and its own words -- "unknown" and why --
because a bar resting at zero because a machine is unreachable reads as
plenty of headroom, which is the opposite of the truth. The window is
selected by the API's own `kind` ("session"), added to UsageWindow in
this change, rather than by matching the label a person reads.

**The token total moved from the header to the bottom right of the
transcript**, pinned above the input rather than scrolling with it. In
the header it was one item in a run of dot-separated facts about the
session and read as another of them, rather than as the running total it
is.

SessionSummary now carries the setup id, which it deliberately did not.
The stated reason was that nothing here addressed a setup and holding
both id and name invited showing the wrong one; the usage bar addresses
one, so the reason lapsed rather than being overruled, and the comment
now carries the rule that replaces it: never display it. The server has
always sent the field, so nothing changed on the wire.

ktfmt, compileDebugKotlin and lintDebug all clean.

irisandClaude Opus 5 1e3eec8cf0 Let a session drop its context without ending
Adds `Event::Cleared`, `SessionCommand::Clear`, and `Driver::clear`, so
`POST /sessions/{id}/command {"text": "/clear"}` does for a session what
the CLI's own `/clear` does for a terminal.

The marker is a divider, not a truncation: everything above it stays in
the transcript, because that is the only copy of the conversation the
phone has and a person scrolling back is a different question from what
the model is given. It also makes clearing mean one thing across
drivers -- `claude` sends `/clear` and the CLI answers with a fresh
`init` whose new session_id the reader already persists as the resume
token, so the next launch resumes the cleared conversation with nothing
to keep in step; `llama` needs no state at all, since `conversation()`
already folds the transcript and now folds from the last marker; `echo`
emits the marker alone, so the phone's divider and scroll behaviour can
be exercised without spending a real session's context.

That fold is why `Cleared` is documented as load-bearing rather than
decorative. For any driver that rebuilds its conversation from the
transcript, this marker decides what the model sees, and treating it as
something only the phone draws would silently put the cleared
conversation back in front of the model at full price.

Clear rides the existing boundary pump like any other SessionCommand, so
one arriving mid-turn waits exactly as a compaction does, and nothing
grows a second way to wait.

Removes `--autocompact` in the same change, because clearing is the
cheaper answer to the problem it was added for and Bryan would rather
manage context that way. Keeping the measurement here, since it was the
reason for the constant and is worth more than the constant was:
context returned to 70-85k within ten calls of a compaction; a
compaction took 104,346 to 147,671 ms; compaction cost that session
2,655,508 tokens across six boundaries, of which the single automatic
one at the 1M ceiling was 1,696,870. Clearing costs nothing, because
nothing is sent.

irisandClaude Opus 5 797513bb86 Raise the compaction window to 200k
100k is the cheapest window on tokens and the wrong one to sit in front
of. Measured on the session this was written against: context returns to
70-85k within ten calls of a compaction, so a 100k window compacts about
every thirteen calls, and a compaction takes roughly two minutes
(durationMs 104,346 to 147,671 across the six recorded). A 130-call
request would have spent some twenty minutes compacting -- optimising
the number that was asked about while making the thing somebody actually
waits for on a phone considerably worse.

200k keeps most of the saving against the 1M ceiling and halves the
stalls.

The comment now also says what the window does not do, because measuring
this turned up the opposite of what the byte counts suggested. Images are
93% of the bytes that tool calls put into that transcript but only 8% of
the context growth -- the adb wrapper's downscaling holds a screenshot to
a median of 476 tokens, while text-only calls add a median of 740 and a
mean of 1,139. So the file is large because of screenshots and the
context is large because of ordinary tool output, and only the second one
is what this constant governs.

irisandClaude Opus 5 4f586d6551 Attribute the drift to the CLI's ceiling, not to a manual compaction
The reasoning on AUTOCOMPACT_WINDOW cited 491,562 tokens as where "the
CLI compacted it". That was a manual /compact somebody ran, not the
CLI's own trigger, so the comment credited a person's intervention to
the automatic behaviour it was arguing about. Caught in review by the
session whose transcript it was measured from.

Corrected from that transcript's compaction boundaries: the window left
to `auto` was 1M, and the one automatic compaction fired at preTokens
1,000,184 with the API context peaking at 999,668. So the drift ceiling
is twice what the comment said, and near it a single tool call bills
about 100k tokens rather than 49k.

The correction strengthens the case, but it also changes what the
example is evidence *of*, which is why it was worth fixing rather than
just raising the number: what held that session together was the person
in it running /compact by hand four times, and the 4.2-million-token
request happened at the merely-large contexts left between those. The
constant is for the sessions where nobody is doing that.

No behaviour change. 68 tests, clippy clean, rustfmt clean.

irisandClaude Opus 5 4a4057886d Compact at 100k rather than letting a phone session drift
Left at `auto` the CLI picks a very large window, which suits a terminal
session somebody closes at the end of the day and does not suit this app
at all: these run for hours, nobody closes them, and the transcript
carries screenshots. One session here reached 491,562 tokens of context
before the CLI compacted it.

That matters because every API call re-reads the whole context, and one
request is not one call. At half a million tokens a single tool call
bills about 49k before it does anything, so "can you make it so you can
rename a session?" cost 4.2 million tokens across the 130 calls it took.
Measured over that session's life: 2,498 calls, 1.08 billion cache-read
tokens.

100k is the smallest window the CLI accepts and roughly the cheapest.
Per-call cost falls with the cap, while the compaction it forces costs
about the same in total either way -- a smaller window compacts more
often, but each pass is proportionally smaller. What it trades is how
much detail survives a compaction, which is a real cost to the work and
the reason this is one named constant with the reasoning written down
rather than a computed value.

Passed before the resume/name branch, so it applies to adopted and
imported sessions too -- which are the large ones, and the ones this is
for.

Verified: the exact argument list the app now spawns starts, accepts an
empty stream-json stdin and exits 0, so the flag combination is good
without spending a token. 68 tests, clippy clean, rustfmt clean.

iris 749b2db287 Make a command a thing the app knows, and hold it until it can run
Typing "/" now suggests what this app understands -- `/compact` and
`/rename <name>` -- with a line each about what they do, and anything
else beginning with a slash is passed to whatever runs the session,
because a dialect's own vocabulary grows without this list.

None of them are messages, and that is the substance of the change. A
line written into a running turn is read by the *model*, so a command
sent mid-turn either does nothing or arrives as text somebody has to
puzzle over. They now wait for the turn to end. The waiting is done once
for every provider, in the pump that already watches every event for the
boundary, rather than in each driver where a new provider could get it
wrong by leaving it out.

Waiting is a state, so it is on screen: the command sits at the reader's
end of the conversation in blue, with a spinner and "waiting for this
turn to end", and becomes an ordinary blue row when it goes. Blue
because these are about the session rather than about the task -- the
same blue a compaction already used, which is now one colour with one
name rather than two.

Renaming from the settings screen sends exactly this, so it waits and
draws the same way. The name itself is not held: it is this server's own
datum, so the list and the header change at once and only telling the
session waits.

Echo grew the same split, which is where the bug in it showed: its
commands are its messages, so running one announced a `MessageTaken` as
well, and the same line drew twice -- once blue, once purple. A command
owes no announcement; the manager has already recorded that it was sent.

Watched rather than reasoned about: `/compact` during a 25 second turn
held with its bubble up, went out when the turn ended, and the
compaction that followed reported what it recovered.
2026-08-29 17:10:21 -04:00
iris bebaae7a94 Carry a question in the event model, not in one provider's JSON
A question is now fully described by the event that reports it: the tag
it was asked under, each option's label, what it means, and the sample of
what picking it would produce, plus whether several may be picked at
once. The app renders from that alone.

It had been reading Claude Code's tool input to find the parts the event
dropped -- that dialect's schema, written out a second time in Kotlin,
where no other provider could reach it and where it would drift the
first time the schema moved. Echo could not describe an option at all,
and llama never will.

Answers travel as a list for the same reason. A question that takes one
answer sends a list of one rather than being a different shape, and the
one place that flattens it is where the CLI is spoken to: its answers
map holds a string, so several choices are joined there. That join was
in the phone.

Also here because it is the same rule: the permission ask reuses the
question body rather than owning a second one, so Allow/Deny renders and
resolves through exactly the code an AskUserQuestion does.

Verified against both, since a refactor that only satisfies the case it
was written for has been tried on the half that cannot fail: a two
question `/ask` answered from the phone, one option and then two, and a
real sonnet session's `rm -f` permission asked, allowed, and run.
2026-08-29 16:46:43 -04:00
iris fea8e7e92b Show every option a question offers, on the call that asked
Reported by Iris through the dev-updater session: a two-question
AskUserQuestion arrived with only one option visible per question, so
the answer she sent was the only one she had been offered.

The cause was a `Row`. It hands out intrinsic widths in order and clips
whatever runs past the edge, so the first option or two drew and the
rest went off the side of the screen -- which does not read as a bug, it
reads as those having been the only choices. The same Row was in the
permission ask beside it; both wrap now. That pairing is the reason to
look: a rule stated on one member of a set is usually missing from the
others.

The rest of what she asked for, and what each was:

- It drew twice, as the tool call and again as loose question cards,
  because the backend marked these questions as belonging to no call.
  They belong to the call that asked, and now say so.
- So it renders like any other tool: one card, its own heading, opened
  because a decision cannot be made from a closed row.
- Each option shows its description and its `preview` block, which is
  the part a reader is deciding on and none of which was reaching them.
- "Other" is a field on every question. The harness always offers it, so
  leaving it out narrowed a question that was never that narrow.
- A multi-select sends the labels it collected as one string, which is
  the tool's own schema rather than a guess -- its answers map is
  string-valued.
- No spinner while it waits. A spinner says the machine is working; here
  the machine is idle and the turn is stopped on the person, so the card
  says "your turn" in the colour this app already uses for that.

Verified against a real session as well as the echo fixture: haiku asked
two questions with three described options each, both were answered from
the phone, and the model carried on with the answers. Echo grew `/ask`
so the shape can be looked at without paying a model to produce one, and
its option cards are outlined rather than tinted -- as one surface step
up they were three paragraphs where three things to press should be.
2026-08-29 16:22:15 -04:00
iris d3fff3d229 Let a session be renamed, under the same name everywhere
A gear at the end of the session's own bar opens what can be changed
about that session; the name is the first thing there. Compact is gone
from that bar -- `/compact` typed into the message box is the CLI's own
way to ask and it already worked, so the button was a second way to say
one thing. Echo takes the typed word too now, since it is the rig the
compaction display is checked against and losing the button would have
taken that with it.

The name is this server's, not a driver's: it is what the list shows, it
exists before any process does, and every provider has one. So it is
settled in the config and the driver is *told* -- which is the opposite
of the model and the permission mode, and the difference is written down
at `Driver::set_title`. A driver whose process has no notion of a name
does nothing and says nothing, because there is no failure to report.

Claude Code has one, so the name reaches it: `--name` for a session we
create, and `/rename` afterwards, which is a local command rather than a
control request -- `set_session_name` is not a subtype it knows, which I
established by asking it. A resumed session is deliberately not renamed
at launch: an import already has a name, quite possibly one the person
typing in it chose, and taking that would be helping itself to something
the app was only shown.

Verified end to end rather than argued: renaming from the phone put
"Session renamed to: paging and scroll" in the CLI's own session file,
and the session now lists under that name to other agents.

The gear is drawn rather than set in a font, for the reason Chevron
gives. It was a sun on the first attempt -- thin teeth standing clear of
a thin hub -- which no amount of reading the diff would have shown.
2026-08-29 16:06:15 -04:00
iris 1629e0911e Say what the line splitter would do with a bare carriage return
`complete_lines` splits on `\n` only, which is right -- this stream is
JSONL, and a record terminated by a bare `\r` would not be a record --
but the doc comment said why the remainder is held without saying what
decides where a line ends.

Worth the sentence because of what the failure would look like if the
CLI ever wrote such a line: the session goes quiet, the process is
healthy, nothing errors, and the cause is a line splitter. The
dev-updater session hit exactly this shape today reading cargo's
progress line, which is `\r`-terminated for redrawing in place, and
lost a whole build's worth of output to it.
2026-08-29 15:42:32 -04:00
iris 3eccf7e443 Show the model and mode the session has, not the ones it was asked for
Picking either from the phone wrote the choice straight into the
session's state and then sent the request. Asking and having are
different things, and the difference is not rare: `auto` is a permission
mode the CLI accepts on the command line, silently resolves to
`default`, and refuses outright over the control channel -- "auto mode
unavailable for this model" -- so a session spawned in auto was in
default and one switched to auto stayed where it was, with the phone
reporting auto in both cases.

So the drivers report what they are set to and the manager follows that.
Measured, because the confirmations are not uniform: a model change
answers success with no value, so what was asked is remembered until the
answer arrives; a mode change echoes the mode it became, and that answer
wins over the request; and `init` names both -- resolving `haiku` to
claude-haiku-4-5-20251001 -- which also covers a session adopted from a
terminal that set them outside this app. A driver that cannot change
either already says so with an error, and now that error is the whole
story rather than a note beside a display that changed anyway.

The config keeps the requested value, deliberately: that answers a
different question, which is what to launch this session with next time.

Two things fall out. Control request ids are random rather than the
clock, because two in the same second shared an id and something now
looks them up. And the phone shortens a resolved name for the button --
`haiku-4-5` -- since the full one is what the CLI reports and roughly
twice the room that row has once Stop is in it.
2026-08-29 15:36:53 -04:00
iris 404066fa7d Say when a session is working, and what it was told
Three things a phone could not see, all of them the same shape: the
session was doing something and nothing on screen said so.

A turn nobody here started never reported itself. `Running` was sent
where a message was *sent*, so a session picked up mid-turn, one
compacting on its own, or one another agent wrote to sat there reading
as idle until it finished. The driver now says it from what it observes
-- output that could only come from a turn in flight -- which is the
same set of events that already announced a steer, with the ends
swapped.

An imported session had it worse: nothing but replayed lines ever
reaches it, and a status was not among them, so it was permanently
whatever it was when it was adopted. Its file does not record a turn
ending, but it does record why each assistant message stopped, and
`tool_use` versus anything else answers it. A record that says nothing
leaves the status alone rather than voting for idle.

Messages from other agents were dropped outright: the CLI marks them
meta, and this replayed everything except meta. They are now a row of
their own, closed by default like a tool call, named for the session
that sent it -- not the reader's own bubble, because they did not say
it, and a session working on something this phone never asked for is
exactly what one of these explains.

Measured against a real session file rather than guessed: the peer
record carries the sender's name and the message body in `origin`,
beside a copy wrapped for the model to read.
2026-08-29 15:27:46 -04:00
irisandClaude Opus 5 fc71cb4403 Say "unknown" for a session we are not driving but cannot bury
A session in the config with no live entry reported `Exited`, whatever the
reason. That covers three different situations -- one that genuinely
ended, one that failed to relaunch, and one whose process could not be
checked -- and the wrong one is the expensive one.

`Exited` reads as "this conversation is over", and what a reader does about
it is start a fresh session. If the process is in fact still running, that
is a second CLI against a conversation that already has one: the exact
fault `session::process` exists to prevent, arriving through the status
field instead of through a spawn.

So it is said only when the process is known to be gone. A record that
cannot be checked reports `Unknown`, and so does one that is still alive --
this server is not driving it, so it genuinely does not know what that
process is doing, and the honest word is the one meaning "wait" rather than
the one meaning "act". A session with no record at all is still `Exited`:
an echo session, or one already stopped and cleaned up, and known to be.

The distinction was available all along -- `process::recorded` returns the
liveness -- which makes this the same mistake as the other five today:
reporting what was convenient to compute rather than what was measured.

iris 5396da76c7 Show a compaction happening, and what it recovered
The Compacting status had been declared, rendered in four places, and
never once emitted: no driver produced it, and the app had no control to
ask for a compaction in the first place. Pressing nothing for two
minutes and then quietly having less context was the whole experience.

The CLI turns out to announce all of it, which was worth measuring
rather than guessing at. Driven through /compact against 2.1.237 it
emits a `status: "compacting"` line at the start, a `status: null`
carrying `compact_result` at the end -- `"failed"` with a sentence
saying why, when it does -- and then a `compact_boundary` with the token
counts. The same records appear in the CLI's own transcript file with
camelCase keys, which is the obvious place to read the shape off and
gets every field name wrong.

So none of it is inferred here. The driver writes the line and says
nothing; the translator reports what the CLI reports. A failed
compaction surfaces the CLI's own sentence, which is specific enough to
act on.

The counts are the part worth keeping afterwards, so they land in the
transcript rather than only in a status that vanishes: a session that
went from 128,402 tokens to 9,617 has just been given its context back.
They are optional throughout, because a compaction whose size nobody
reported has to be able to say so -- a zero would read as "recovered
nothing".

Also here, all found on the way:

- `rename_all` renames variants; fields need `rename_all_fields`. Every
  field in Event was a single word until `pre_tokens`, which went out as
  snake_case, was not found by the app, and rendered as the "no counts
  reported" case -- a state it is allowed to be in, so nothing looked
  wrong. There is now a test on the wire names.
- The unparseable-line warning sliced bytes, not chars, on output that
  is full of em dashes. A panic there kills the task reading the
  session's stdout, and the session goes deaf with nothing on screen.
  The other three truncations in the tree already did this correctly.
- Echo compacts too, with invented numbers and a real shape, so this
  screen can be looked at without spending two minutes of somebody's
  account to reach the state.

irisandClaude Opus 5 42131c75d6 Send a steer into the running turn, and put an image under its call
**The queue was holding messages the CLI would have taken.** Two claims
in this file contradicted each other: the module header said a mid-turn
message is injected at the next tool boundary -- "the behavior this app
exists for" -- and `Queue`'s own doc said a line written mid-turn simply
becomes the next turn. The code followed the second, parking every
message until `Status::Idle`, which is the end of the whole turn.

Measured rather than argued, twice. Writing a line straight into a live
session's stdin fifo mid-turn produced one `result` for the whole thing,
so it was consumed inside that turn, not as a new one. The header was
right and the queue was built on the wrong claim.

The cost was exactly what Bryan reported: he steered after the second
tool call and it sat unread until every remaining call had finished.
Measured before and after on the same three-step turn -- steer sent at
+13s, recorded at +24.7s before this change and at +14.1s after, which
is the next tool boundary.

So the line goes out immediately. What stays behind is the
*announcement*: the CLI says nothing on stdout about having read a
message, so `MessageTaken` now waits for the next assistant text or tool
call, which is proof another model call happened and the steer was in
it. That keeps a held message drawn below the working indicator until
the session has actually taken it -- the thing that mattered when this
was last changed -- without delaying the message to get it. Idle counts
too, and is the case that must not be missed: a message written after a
turn's last model call has no later output to prove anything.

`closed` is untouched, and `Queue::close` still reports held messages by
name rather than dropping them.

**An image now names the call that produced it.** `Event::Image` gains
`about`, the `tool_use_id` from the tool result it came out of, so a
screenshot is drawn inside that call's card instead of floating beside
it -- pairing them by position is what a page boundary breaks. `None`
for a person's own attachment, which belongs to no call. The import path
threads it through as well, so replayed history reads the same as live.
Images show whether the card is open or closed: a call whose result *is*
a picture says less closed than the one line it replaced.

Verified on the emulator against a real haiku turn: the checkerboard sits
inside `Read /tmp/tiny.png`, and the steer sits between that call and the
next, where it was taken. 53 tests, clippy, rustfmt, lint and ktfmt clean.

irisandClaude Opus 5 011ed0d0e1 Hold an image's place, open it full screen, and fold a run of calls
Five changes to how a transcript reads.

**Images no longer move the page.** The row was as tall as whatever had
loaded, so it grew when the bytes arrived and pushed everything below it
-- and in a bottom-anchored list, an image loading above the viewport
moved the text under the reader's eyes. The height is now decided before
the fetch and never changes: four lines of the body style, measured from
the type so it stays four lines when the reader has scaled their fonts.
Nothing to see when loading finishes, which is the point.

**A small image is enlarged with nearest neighbour**, a large one shrunk
smoothly -- decided per image from its actual size rather than set once,
since blowing a 16px sprite up with interpolation turns it into a blur
of exactly the thing being looked at.

**Tapping one opens it full screen**, fitted so the whole image is
visible first, with two-finger zoom to 8x and pan once zoomed. A dialog
rather than a screen, so back returns to the transcript.

**A tool call is one line closed**: the tool's name and what the call is
for. The command is not on it, because a wrapped command turns one row
into four. Open, it shows the command, the rest of the input and the
output, with the timeout at the top right -- a limit on the call rather
than part of what it does, worth seeing beside the command it constrains.
A call waiting on permission is shown open regardless, since the command
is the thing being decided.

**Adjacent calls fold into "Called n tools"**, closed by default, and it
closes again from either end -- a long group's heading scrolls away while
its last call is still on screen, and the reader who wants it shut is
looking at the bottom. The calls keep their full width; what says they
belong together is the surface behind them, one cue rather than two
half-cues. Grouping happens at display time, not in the fold: the
transcript's own order is what paging and the stream depend on.

Echo gains `/tools [n]` so a run of calls can be produced without paying
for one.

Verified on the emulator: four calls folded and expanded, one opened
inside the group showing `timeout 5000` top right, a 16px checkerboard
enlarged with hard pixel edges beside a shrunk screenshot at the same
height, the screen byte-identical between one second and six after
opening, full screen fitted, and back returning to the same scroll
position. Pinch itself is the one thing not verified here -- `adb input`
cannot inject a two-finger gesture.

53 tests, clippy, rustfmt, Android lint and ktfmt clean.

irisandClaude Opus 5 c5dbd1535d Ask for permission on the call it is about, and read the input
A bash permission request arrived as a second card repeating the tool
call's input verbatim, so the same command appeared twice and the reader
had to work out it was one event. `Event::Question` now carries `about`:
the `tool_use_id` the CLI's `can_use_tool` request already names. That
makes the pairing a measured fact rather than a match on input text --
and it stays `Option`, because AskUserQuestion is not permission for
anything and an echo session's question is about no tool at all. Those
still draw as their own card, which is what every question did before.

The card also reads the input instead of dumping it. Every tool's input
is JSON, and showing it raw makes the reader parse `{"command":"…",
"timeout":5000}` to find the line they care about. A small table says
which field is the subject of which tool -- Bash's `command`, Read's
`file_path` -- and the rest is still listed, since dropping a field
would claim the tool had no other input when it might. The subject is
syntax-highlighted with dev.snipme:highlights, for the reason the
markdown renderer is a library: lexical rules are somebody else's
specification. Its theme is Catppuccin, mapped in Theme.kt beside the
rest of the palette rather than taken from the library's defaults.

The input shows whether or not the card is expanded. A row that says
only "Bash" says nothing anyone can act on, least of all when it is
asking to run something.

Verified on the emulator against a real haiku session: one card, the
description, `grep -rn "needle" /tmp | head -3` highlighted, `timeout:
5000` pulled out, and "Allow Bash?" with its buttons inside the card --
then Allow, which resolved in place and ran.

It had landed appended to `SshRequest`'s doc comment, so a rule about
every request body in the module read as something about how to describe
a machine. Moved to the module doc beside the route table, where the set
it governs is what a reader is already looking at, and worded so a new

irisandClaude Opus 5 446fb92ba3 Refuse a request field the server does not know
A misspelled field was accepted and dropped. Sending `permission_mode`
instead of `permissionMode` produced a 200 and a session running in the
default permission mode -- so the caller's setting was gone, and nothing
anywhere said so. That is the expensive shape: indistinguishable from
success at the place you are looking. It cost an hour here, chasing a
"startup race" that was a key serde had silently discarded; with the name
spelled the way the API asks, a bypassPermissions session runs a `sleep`
loop with no prompt at all.

So every request body refuses unknown fields, not just the one that bit.
Axum's message names the offending field and lists what was expected,
which is the whole of what the caller needs.

Query strings are deliberately left permissive: a stale link carrying an
extra parameter is not a mistake worth failing a request over.

53 tests, clippy and rustfmt clean; verified against the running server
that the misspelling is now a 422 naming the field and the correct
spelling still spawns.

irisandClaude Opus 5 d8570f4d5a Ask each machine about its own limits, not this one about all of them
`ClaudeUsage` read `~/.claude/.credentials.json` on the machine running the
backend and asked the API about that account, once, globally. But a session
runs wherever its setup says, so the numbers on the usage screen belonged
to the backend's account rather than to the account that spent the tokens.

That is not a rounding error in the layout this project is aiming at.
`ai-server` belongs on the host; the host has no `claude` CLI at all and
the VM is a remote. So the screen would have reported "is Claude Code
logged in on this machine?" while every session ran fine on a machine whose
limits nobody could see. It looked correct only because backend and CLI
happen to be the same box today.

Usage is now per machine, asked through the same `Transport` the sessions
use -- `ssh host sh -c 'cat $HOME/...'` for a remote, unchanged for the
local one. `$HOME` is left for the far shell to expand, since a path built
here is this machine's home directory and over ssh that is somebody else's.
Machines with no Claude provider are not asked and get no row: they have no
Claude limits, and a row about them would be a fact about nothing.

The snapshot gains the states it could not say. `available` plus an `error`
string made three different situations look identical, and the one that
suffered was the harmless one: a machine nobody has logged in on is a
decision somebody made, with nothing to fix, and it read as broken.
`notLoggedIn`, `unreachable` and `failed` are now distinct, and which one a
failed read is gets decided in `why_no_credentials` rather than at the call
site.

Supporting changes: `ssh::command` builds a `std::process::Command` that
tokio converts from, so a blocking caller can use the one place that knows
what a correct ssh invocation is; `Transport::capture_blocking` is that
caller's door. The cache is keyed by machine and service rather than by
position, since the set is no longer fixed at startup -- a positional cache
would hand one machine's numbers to another the moment a setup was added.
A cached snapshot still picks up a rename immediately, because the name has
nothing to do with the poll interval.

Verified against a real ssh setup (loopback, per AGENTS.md) with five
machines, all four states seen: local `ok`, loopback-over-ssh `ok`,
unreachable host `unreachable` carrying ssh's own message, a claude-less
machine correctly absent, and -- with the backend's HOME emptied -- local
`notLoggedIn` while the ssh machine still reported real windows, which is
the production shape.

irisandClaude Opus 5 9f403cddab Render markdown, and stop wiping messages still waiting to be read
Two things, both about the transcript telling the truth about itself.

Markdown is rendered rather than shown as its source. The parsing is
mikepenz/multiplatform-markdown-renderer, not something written here:
markdown is somebody else's specification, and a hand-written subset of
one disagrees with it at the edges, which is where the bug reports come
from. `Markdown.kt` is only the mapping onto this app's palette, so code,
links and rules take the Catppuccin values the rest of the app uses
rather than the renderer's defaults.

The queued-message list was cleared wholesale whenever a turn ended. But
the backend holds a queue of its own and takes one message per turn, so a
turn ending is precisely the moment the *rest* are still waiting -- the
bubbles vanished while the messages were on their way, which reads as
everything after the first having been dropped. Now a held message
leaves the list exactly two ways: the session reads it, which arrives as
a UserMessage, or its send failed and there is nothing to wait for.

Measured first, because the report was that the backend dropped them:
three messages sent behind one long turn were all delivered in order
(ONE, TWO, THREE) against current main, so the loss was in the display.

Verified on the emulator: headings, emphasis, inline code, nested lists,
a quote bar, a fenced block, a rule and a link all render, and the three
queued messages sit through their turn.

irisandClaude Opus 5 19e3525131 Say what continuing a session will cost, not just how big it is
The import list reported a file size, which predicts the wrong thing. Most
of a large transcript is history from before a compaction, and the model is
not given it again: of the 133 MB session behind the 2026-08-29 incident,
99% of the bytes sat before its last compaction summary.

So each row now carries the tokens the model was actually holding at the
last turn -- the input side of the most recent assistant message's usage,
prompt plus both cache figures, which the CLI records itself rather than
anything inferred from the file. The two disagree in exactly the way that
makes the size misleading. Measured on this machine: `ai-app` is an 80 MB
file with 150k of context, while `ai-app-backup` is 3 MB with 481k. The
smaller file is the more expensive one to continue.

Absent rather than zero when no turn has recorded usage, since a session
with no turns has no figure rather than a figure of none.

The row is three lines instead of one run of separators:

  path      cut at the head, keeping the tail, and the only thing here that
            is cut -- one long value with no natural break, where the lines
            below it are short enough to wrap
  stats     named, context, lines, size
  warning   only when there is one, in the warning colour

The warning gets its own line and its own colour because it differs in kind
from the stats rather than in degree: those describe the session, it says
whether taking it is safe at all. Colour makes it findable, the words make
it actionable -- "open somewhere else" and "we could not check" are not
distinguishable by shade.

Titles no longer ellipse either; they wrap.

Looked at on the emulator rather than reasoned about, including the states
that are not the default: a long path truncating, a row with no warning,
and a row with no context figure.

irisandClaude Opus 5 c1a468432d Read a session's transcript once at launch, not twice
Reading the last status back from the transcript -- added so a restart
stops claiming an exited session is idle -- walked the whole file a second
time, after `Transcript::open` had just walked it for the sequence number.
Both answers are wanted at the same moment by the same caller, so the cost
was paid per session at exactly the point a restart is trying to be quick.

`Transcript::open` now finds both in its one pass and reports the status it
saw. The free function goes; a transcript knowing what it last recorded is
where that belongs anyway.

irisandClaude Opus 5 3a74bd9c35 Make the process record survive a crash mid-write
Reviewing the reattach code found the fault it exists to prevent, sitting
in its own save point.

`process::write` used `fs::write`, which truncates before it fills. A crash
inside that window leaves no readable record -- and a missing record reads
as "nothing is running", which is the single answer that makes the next
launch start a *second* CLI against a conversation that already has one.
The window is not rare: the record is rewritten on every read that makes
progress, so many times a second while a turn is producing output.

Written to a neighbouring file and renamed over the real name now. The
rename is atomic, so a reader sees the whole old record or the whole new
one. That also makes the fixed-size padding pointless -- a rename replaces
the file rather than overwriting part of it -- so it goes.

Two more from the same pass:

- A failed read of the stdout log was logged and nothing else. The session
  then went deaf with nothing on screen: no more output, no error, a status
  that stayed wherever it was. It now says so, closes the queue rather than
  stranding messages in it, and reports `Unknown` -- not `Exited`, because
  the process may well still be running; what failed is this server's
  ability to hear it.
- Sizing the stderr log by reading it. `read_from` with a large offset
  answers "how long is it" by allocating the whole file first, which on a
  chatty process is a large pointless read on every reattach. `size_of`
  asks the filesystem.

irisandClaude Opus 5 d7c692a4ec Show a replayed session's images instead of dropping them
An imported session showed no screenshots. `text_of` kept only `text`
blocks, so every image in the replayed tail was silently discarded -- while
the *live* translator has always saved them into the session's `files/` and
referenced them. Two readings of the same records, and the one used for
history was the lesser.

`save_image` moves out of `Translator` to a free function both paths call,
since the naming scheme for that directory should exist once. `events_from`
now takes the session directory to write into, which means the conversion
has to happen where that directory exists -- so `Seed` carries the raw
JSONL and `launch` turns it into events, rather than `routes` doing it
before the session is created.

Costs nothing in tokens, which is the point worth recording: this writes
into ai-app's own session directory and the phone fetches a reference only
when it draws one. Nothing here is ever written to the CLI's stdin -- it
reads its own session file, and the only things this app sends it are typed
messages, control requests and `/compact`.

Verified against the 133 MB session behind the 2026-08-29 incident: 45
images in the replayed tail, written as real PNGs and served over the files
route, with the transcript itself staying at 756 KB of references.

irisandClaude Opus 5 d96bc041a7 Say how big a session is before it is imported
The import list reported a line count, which is the wrong axis: these
transcripts embed screenshots as base64, so one line can be a megabyte.
On this machine a 69 MB session has 3,427 lines while a 44 MB one has
6,792 — the number on the row said nothing about what continuing the
session would cost, and size is the only thing there that predicts it.
The session behind the 2026-08-29 incident was 65 MB across 13,000 lines,
a line count that looks unremarkable.

Shown beside the line count rather than instead of it, since a short file
of long lines is exactly the expensive case. Not warned about and not
marked: importing a large session is a choice somebody is entitled to
make, and flagging it would be the interface nagging about a decision
already taken.

irisandClaude Opus 5 362d436d4f Let sessions outlive the backend, and never resume one twice
Three `claude` processes ended up running against this checkout on
2026-08-29, and the account hit its session limit. One cause, several
ways in.

An agent imported the Claude Code session it was *itself* running in.
That is an ordinary import, and importing runs `--resume` -- so a second
CLI attached to a file the first was still writing. The whole 65 MB
conversation, 154 embedded screenshots included, was re-appended to the
transcript under a new prompt id; both copies then read each other's
writes as work done elsewhere, and the adopted one was billed for
re-reading all of it. Meanwhile `shutdown_all` asked each session to stop
and the process exited immediately, so the SIGKILL timer died with the
runtime, the stop was unreliable, and whatever survived was orphaned with
nothing written down to find it by.

The processes leaked either way. So leak them on purpose, and be able to
pick them back up.

A session's process now outlives the backend and is adopted again on the
way up, which is worth having for its own sake: restarting the server no
longer ends a turn somebody is waiting on. Its stdio lives in the session
directory -- a fifo opened read-write so the process is its own last
writer and never reads EOF, plus stdout/stderr logs read from a byte
offset. `session::process` records the pid *and* the kernel's start time
for it, because a pid alone is reused and adopting a stranger's would mean
never resuming the real conversation.

That makes the fix structural rather than a check: everything goes through
`ClaudeDriver::launch`, which adopts if it can and starts if it cannot,
and `--resume` is reachable only on the second path. `Driver` gains two
ways out where it had one -- `detach` (coming back) and `stop` (the
session is being deleted, so the process must not survive).

Importing a session that is open is now refused outright. Claude Code
keeps `~/.claude/sessions/<pid>.json` for every live session, so this is a
measurement rather than a guess; it reports no/yes/unknown, because a
machine that keeps no such record cannot answer and "could not check" is
not "nobody is using it". `SessionStatus` gains `Unknown` for the same
reason.

Also here, found on the way:

- A reconnecting phone was sent the entire backlog. Opening a session was
  bounded to a page but reconnecting was not, so a long disconnect
  delivered thousands of events one frame at a time. Past `CATCH_UP_LIMIT`
  the stream sends a `reset` frame and the newest window, and the client
  rebuilds from it as it does on open -- without the reset the window is
  spliced onto rows no longer adjacent to it.
- A session's status was assumed idle at launch. Read from the transcript
  instead, so a restart stops claiming an exited session is waiting for
  you.
- `llama-server`'s stdout was piped and never drained, so a chatty one
  blocked on a full pipe buffer mid-load. It goes to a log now.
- A turn that exited or errored never emitted `Idle`, so the queue stayed
  "running" for good: every later message was held forever and, since a
  message is only recorded when taken, vanished with nothing on screen.
- Two doc comments had drifted onto the wrong functions.

Verified by killing the server mid-turn: the process survived, finished
its turn unattended (12.8 KB of output nothing was reading), and the
restarted server adopted it -- one process, all 700 lines in the
transcript, no hole, and it still took a new message afterwards. Deleting
a session stops its process; a 266-event backlog resets while a 16-event
one streams. 46 tests, clippy and rustfmt clean, app compiles and lints.

iris 2fe34176c0 Give the transcript a way back, and stop losing an import's name
**Every imported session was called "claude-cli session".** The app has
nothing to say about the title -- the server names it after the session it
is continuing -- so it sent `""`. That is `Some`, which satisfied the
`or_else` meant to catch "no title given", so the imported name was
computed and then thrown away in favour of the `<provider> session`
fallback.

Normalised at the boundary instead: blank means absent, because that is
what it means to the person who left it blank. Both the client's value and
the imported one go through the same trim, so neither can be a string of
spaces standing in for a name.

**And a jump-to-latest button**, shown only while the newest message is
off-screen. Reading back through a conversation is a place to be rather
than a state to be rescued from, so it waits to be wanted and leaves once
there is nowhere to jump to.

It says where it goes instead of drawing an arrow. The list is laid out
from the bottom, so "down" in the data is up on the screen, and an arrow
would be asking the reader to hold that in their head to press a button.

Verified on screen: an import now arrives titled "ai-app" rather than
"claude-cli session", and the button appears on scrolling back, returns to
the newest message, and disappears on arrival.
