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. |

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. |

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. |

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.

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. |

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.

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.

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.

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.

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.

Stop choosing a model, and keep an imported session up to date
**Why the model became fable.** `spawn_session` fell back to the
provider's first listed model when none was given. That list is a shortcut
for the spawn screen, written in whatever order somebody typed it, and its
first entry is `fable` -- so every session spawned without a model, which
is every import, silently became a fable session. It looked like a default
and was an artefact of list order. Absent now means absent: no `--model`
flag, and the CLI uses whatever the person configured for themselves.
**Model and permission mode are now visible and changeable** from the
session, as buttons that read as their current value rather than labels
beside one. The mode was spawn-only; the CLI turns out to accept
`control_request{subtype:set_permission_mode}` and echo the mode back,
probed against 2.1.237 the same way the rest of the protocol record was.
Both default to `auto` -- on a phone every ask is a round trip to a
question card, which is how "allow Bash?" became the most-answered
question in the app.
The mode is reported by the API so the picker shows what the session is
actually set to, and it is kept in the live session beside the model for
the reason the model already was: `meta` is the shape a session was
*launched* with, so reporting from it shows the value a change replaced.
**And an imported session keeps itself level with its source file**, so
work done at a terminal arrives without a button. `--resume` appends to
the same transcript rather than forking -- measured, not assumed -- so the
only hard question is which new lines came from here.
Answered by counting the events this session has recorded. Status is the
obvious signal and is wrong, which cost a round trip to find: a turn that
starts and finishes between two polls reads as idle at both, so its output
is replayed on top of itself. It showed up on screen as `donedone`, and
only because the reply was one word -- with a longer answer it would have
looked like the model repeating itself.
Verified against both halves: text appended to the source file the way a
terminal writes it appears within one interval, and a message sent through
the app appears exactly once, before and after a turn.

Name a session in the import list, and let one be deleted
Three things about finding a session in a list of seventy, and one about getting rid of it. **A name beats anything inferred.** `/rename` appends a `custom-title` record, so if somebody has said what a session is, that is the row. Eleven of the seventy here turned out to be named already and none of it showed. **Otherwise the last thing said, not the first.** The question this list answers is "which one was I just in", and a session's opening line is the least distinctive thing about it -- several of these begin with the same slash command. Finding that last message took three tries, and the two wrong ones are worth recording because they failed in opposite directions. Grepping the user record type caught tool results, which are *also* user records -- so a session that ended mid-tool showed a tail of empty records and a row saying nothing was said, when plenty had been. Narrowing to a string `content` fixed those two and broke twenty others, because a message carrying an attachment stores its text in a list. Excluding `tool_use_id` keeps both shapes of a real message and drops the one that is not: seven rows still have nothing to show, and those are sessions that really are empty. **Sorted by when it was last used**, and the time is on the row. Naming was tried as the first sort key and is a worse list -- it buries what somebody was just doing under everything they ever named. A name is for recognising a row, not for ordering it, so it stays as the title and as a word beside it. **And a session can be deleted**, which is asked before it is done. The transcript *is* the session, so this ends any chance of resuming that conversation, and the dialog says exactly that rather than "are you sure?". Deletion resolves the id against what the machine reported, like importing, so no path crosses the wire in either direction. Looked at on the emulator, including the dialog -- which is where the delete button turned out to be missing entirely after a patch that compiled fine, and where the row layout got its second look. |

Import a Claude Code session the machine already has
Claude Code keeps every session as JSONL under `~/.claude/projects/`, and the CLI continues one with `--resume <id>`. `claude.rs` already resumes whenever it finds a resume token in the session directory, for crash recovery -- so importing is that same path with the token written before the driver starts, and there is deliberately no second way to begin a session. The seed goes through `launch` with the ordinary spawn, so the driver never learns which kind it got. Two things the machine answers and the phone does not. **Which sessions exist.** One command per setup rather than one per file, for the reason discovery already gives: over ssh each would be its own connection. Titles come from the first few user records rather than the first, because a session opens with records the CLI injected -- slash commands, caveats around local command output -- which are stored as ordinary user records without the meta flag, so titling by "first user record" produced a list where most rows read `<command-name>/clear`. **Which file an id names.** The phone sends an id and never a path; the server looks it up again among the sessions it enumerated. An enrolled token must not be able to turn a spawn into "read me this file", which is the same rule that keeps a provider's command out of `POST /setups`. Only the tail is replayed. The imported conversation is for reading -- continuing it is the CLI's job, and it reads the whole file itself -- so this is a display budget, and it has to be one: the session this was written in is 39 MB, and all of it would otherwise cross a tunnel to a phone. A recorded working directory can outlive itself, which this found immediately: every session from before the checkouts moved to `~/repos` still records `~/host/repos/...`. Resuming into one fails at `cd` before the CLI starts -- a confusing way to meet a feature whose promise is "carry on where you left off" -- so the directory is checked, and a missing one is dropped with a log line naming it rather than being passed on to fail. Verified against this very session: 905 events replayed from the tail (351 tool calls, 350 results, 185 assistant messages, 19 mine), the resume token pointing at its id, and the stale directory reported and dropped. The list was read on the emulator, where the top row is that session under its opening sentence. |
