A notification arriving while the app was open was shown as a banner and
nowhere else, so a moment that happened while the phone was face-up on a desk
left nothing behind at all -- the banner is seconds long and reaches only
somebody already looking.
The two are not two versions of one thing: a banner interrupts and a row
records. Both go up now, and the banner having done the interrupting is what
makes the row a silent one (`setSilent`), so one moment is worth a noise once.
What keeps the drawer from filling up is the other end rather than suppression,
and already was: opening a session clears whatever is posted about it, whichever
way the reader got there.
Checked with ktfmtFormat, compileDebugKotlin, testDebugUnitTest and lintDebug,
and on the emulator against the sandbox, reading the posted record out of
dumpsys: app on the session list gives a banner and flags=AUTO_CANCEL|SILENT;
app backgrounded gives flags=AUTO_CANCEL; opening the session leaves nothing
posted about it in either case.
A call left its group only while it was running, so the moment a command ended
it vanished behind "Called 3 tools" -- and a session that has run its last
command and is composing its answer, or has finished the turn entirely, spends
most of its time in exactly that state. What folds a call back into its run is
therefore not finishing but being overtaken: anything arriving behind it, a
reply included, makes it history.
Standing outside the run is the call's place in the list as it is now rather
than something recorded on the call, so it is asked of the list while grouping
it, where the rest of that decision already lives.
Checked with ktfmtFormat, compileDebugKotlin, testDebugUnitTest and lintDebug,
and on the emulator against the sandbox: "/tools 3 1" settles as "Called 2
tools" with the third Bash card beneath it, and folds to "Called 3 tools" the
moment the next reply lands.
A run of adjacent calls is drawn as one collapsed card, which hid the one
thing worth seeing without opening anything: the command the session is
running right now. It is a row of its own while it runs and folds back into
the run when it ends.
Grouping stays a display decision, so the pieces a running call cuts a run
into are keyed there. The first piece keeps the run's name -- that name is
what survives a page of history landing in front of it -- and later pieces
take their own first call's id behind it, since the call a run was named
after can itself be the one running.
The echo rig's /tools gap now runs between a call's start and its end rather
than between one call and the next, which is where a real session's time goes
and what makes the running state observable at all.
Checked with ktfmtFormat, compileDebugKotlin, testDebugUnitTest (new
ToolRowsTest) and lintDebug, cargo fmt/clippy/test, and on the emulator
against the sandbox: "Called 2 tools" with the live Bash card beneath it.
A message typed during a turn reaches the model at the next model call if
the turn has one left, and otherwise as the opening line of the next turn --
Claude's read out of the fifo after the turn ended, Codex's requeued when
turn/steer is refused. Read there it is indistinguishable from a reply, so
the model treats the answer it just gave as seen.
Both drivers now compose the text the CLI receives through
driver::message_body, which prefixes a note saying the message was written
without having seen the rest of that turn. The transcript still holds the
words that were typed; only the CLI's copy carries the note.

Removing `Event::TaskNote` hours after adding it made every transcript that
had recorded one unreadable. `Transcript::open` parses every line, so `launch`
failed for those sessions and `SessionManager::new` logged
"couldn't relaunch session <id>" and skipped them -- and a skipped session has
no pump and no driver. On the phone that is no status, no history and nothing
sendable, for every live session that had run a background task. One
unfamiliar word took down every conversation it appeared in.
A transcript is append-only and permanent, so the set of kinds one can hold
only ever grows: what this build writes is not what it may have to read. A
line can come from a newer server, or from an older one that wrote a kind
since dropped, and neither may be able to end the file.
`Indexed::parse_at` degrades a line it cannot make sense of to
`Event::Unreadable { kind }` instead of failing the whole read. It keeps the
line's seq -- the cursors, the page bisection and the next-seq counter are all
addressed by it, and dropping the line would hand out a seq the file already
contains -- and carries the word the line called itself, so the phone can say
what is missing rather than that something is. A line with no readable seq is
still an error: that one cannot be placed at all.
`Event::TaskNote` comes back retired rather than deleted: deserializable,
never constructed, dated, with the reason on it. The phone folds it to no row,
which is the point -- an unreadable line correctly draws a placeholder, and
one per background task is the wall the row was removed for in the first
place.
Found while diagnosing a report that live sessions had lost their status and
could not be sent to. 173 server tests pass, including the new one, which
fails on the old code within a second.

A backgrounded command has no subagent, so there is no second transcript for
its report to live in and its own tool card is the only record of it anywhere
-- and until the task notification arrives that card is showing the launch
result, which says the command is running. It was left saying that for ever.
The report now updates the call's own row (`Event::ToolUpdate` against its
tool_use id), so the card ends up holding what became of the command instead
of a claim nothing was ever going to correct. That includes the endings that
carry no summary: those are exactly the ones that went wrong, and a stale
"running in background" reads worst on them, so they say the status word
rather than nothing. A task with a subagent behind it is untouched and its
report stays where it was, in that subagent's own transcript.
Echo grew `/background [seconds]` for the shape end to end: the Bash call, the
launch result, a turn that ends `waiting`, and the completion arriving later
to correct the card and start a second turn.
Verified on the emulator: the card reads `Background command "sleep 5 && echo
done" completed (exit code 0)` where it had said "Command running in background
with ID: ...". 172 server tests, ktfmt, clippy, rustfmt, Android lint and the
JVM unit tests clean.

A row per finished background task is a screenful of dividers about work the
reader was not asking after, and one of them turned out to be a whole shell
command drawn as centred prose, because its words came from somewhere with no
reason to keep them short. `Event::TaskNote` is gone entirely, along with the
row that drew it. A subagent's closing report is recorded as that subagent's
own transcript's closing text and is read in the subcard, which is where it
was already going; what the parent gets a row for is a message a subagent
genuinely sends it, which arrives by the peer path and has had one all along.
What remains is the actual defect and the smallest thing that fixes it. The
fold still refuses to grow a settled reply, so a turn boundary is always a
message boundary, and where two replies then abut it puts a `TurnBreak`
between them: a hairline, no words, no colour. Made by the fold rather than
sent by the server, because it is not something that happened -- it is the
boundary between two things that did. `joinPages` puts one in at a page seam,
which the fold never gets to see.
The task notification is still what closes a task in `Status::Waiting`'s
bookkeeping, and the registry lookup that recognises one this translator never
saw start is what makes that work for a session adopted across a restart.
Verified on the emulator: three replies, three rules, and nothing about the
helpers anywhere in the parent. 170 server tests, 85 JVM tests, ktfmt, clippy,
rustfmt and Android lint clean.

Two corrections to the previous commit.
A subagent's closing report belongs in the subagent's transcript, which is
where it already is; drawing it as a card in the parent's put the same
paragraph in two places for a reader who did not ask for it. The row is a
divider now -- a boundary, which is what the transcript actually needed there
-- closed, saying only what reported and how it went. Opening it shows the
report anyway, since leaving the conversation to read one line has its own
cost, and a backgrounded command has no transcript of its own so this is the
only place its report exists at all: that one names itself from its summary
and has nothing left to open. `TranscriptDivider` grew a `trailing` slot for
the chevron rather than the row growing its own copy of the rules.
And the status was wrong for a session that was already running before the
update, which is every session when the backend is replaced under it.
Adoption picks a session's stdout back up from a recorded offset, so the
`task_started` lines for subagents launched earlier are behind it and the
translator never saw them -- it started with an empty set and reported `idle`
with a subagent plainly still working. `Subagents::any_open` reads the
directory instead, which is a measurement rather than bookkeeping and is right
for a session this process did not start. Both sources are kept and neither
subsumes the other: the translator's own set is the only thing that knows
about a backgrounded *command*, which has no subagent to be found. The same
pair decides whether an ending has already been reported, so a task that began
before the restart still gets its divider.
Echo's helpers now record their report as their own subagent's closing text,
the way the real driver does, so the fixture has the shape being tested.
Verified on the emulator: three dividers closed, one opened to its report, and
each reply drawn as its own message. 170 server tests, ktfmt, clippy, rustfmt,
Android lint and the JVM unit tests all clean.

A turn started by something with no row of its own -- a subagent reporting
back, a peer message the CLI only owns up to at the end -- met the previous
reply with nothing between it, and the fold grew that reply rather than
starting a new one. Two answers were drawn as one paragraph, running together
mid-sentence with not even a space between them. The fold now refuses to grow
a settled reply, and `joinPages` carries the same rule across a page boundary.
The other half is the row. `Event::TaskNote` records a background task
reporting back -- a subagent that finished, or a backgrounded command -- with
its title, how it ended and what it said; `TaskNoteRow` draws it as a card,
since somebody said this, and its own row rather than an update to the Task
call's, which is above everything the session has said since. Reported once
however many of the CLI's two lifecycle shapes arrive.
`SessionStatus::Waiting` is a session whose own turn is over while work it
started is not. `Idle` means "waiting for a person" and this means the
opposite, so reporting it as idle sent a "finished" notification at the one
moment that was untrue. Drawn as "waiting" in `waitingColor`; the queue and
the held-command boundary release on either end-of-turn status, so a message
sent while a subagent runs is not held until it finishes.
And a usage limit the account hits inside a subagent now reaches the session
as well as the subagent's transcript. `resume.rs` can only schedule against a
session, and a background Task outliving its parent's turn is the ordinary
case, so auto-resume was doing nothing at all for it.
The status word and its colour were two `when`s on two screens, and the second
missed `waiting` silently; they are `sessionStatusWord`/`sessionStatusColour`
now. Echo's `/subagent n` reproduces the whole shape, staggered a second
apart. Verified on the emulator against the sandbox: 169 server tests, ktfmt,
clippy, rustfmt, Android lint and the JVM unit tests all clean.

Subagents were showing "running" long after they had finished. Measured
against 2.1.237 by running a session that launched one Task agent and
reading its stdout: a subagent's lines carry no `stream_event` at all --
they are whole `user`/`assistant` lines with a null `stop_reason` -- and no
`result` line is sent for one. So `ends_a_turn`, which watches for a raw
`message_delta` saying `end_turn`, could never fire for a subagent, and
nothing finished one until its session's process exited.
What the CLI does send is a task lifecycle, as top-level `system` lines:
`task_started` (with the tool_use id), `task_progress`, `task_updated`
(status, naming the task only) and `task_notification` (tool id, status, and
the agent's own summary). `translate_task` keeps the task -> tool mapping,
records the summary as the subagent's closing text -- the run showed its
child lines stop at its last tool_result, so without this a finished
subagent reads as stopping mid-tool -- and ends it. A `completed` update is
deliberately not the end, since its notification carries the summary; any
other terminal status is, because the failure to avoid is a subagent nothing
ever finishes. `ends_a_turn` stays as a second detector and must never be
the only one again. Verified by replaying the captured stream through the
server as a fake CLI: running, prompt, Bash call, output, report, exited.
`finish_all` now reads the directory rather than the live map, which is what
clears the ones already stuck: a subagent left running by an earlier run of
the server is exactly the one this process never touched, so it read
"running" again every time its session was started.
Auto-resume gets the same treatment on its own single point of failure. The
only thing that scheduled a resume was the CLI's error sentence at the end
of a failed turn; the CLI also sends `rate_limit_event` lines saying where
the account stands, and this server ignored them entirely. Both are read
now. Anything that is not an `allowed...` status counts as refused and is
logged if unfamiliar -- being wrong that way costs one question to the usage
meter, which is still what decides whether anything is sent, and being wrong
the other way is the feature silently not existing.

A subagent is a second transcript owned by a session, in the same event
model, with no process and no controls. The claude translator routes lines
carrying parent_tool_use_id to a per-subagent translator and transcript
under <session>/subagents/<tool_use_id>; three routes expose the list, a
transcript page and the SSE stream. Echo grows /subagent [n] as the rig.
On the phone a card with subagents ends in a chevron expander, collapsed by
default, opening to outlined subcards styled like dev-updater's components;
a subcard opens SessionScreen in read-only form, addressed through
TranscriptAddress so paging, cache and stream are shared.

Off by default and per session: it spends quota the moment quota exists,
with nobody watching, which is not a thing a default may decide. Switched
on from the session settings dialog, with the message it sends editable
("continue" unless something else is typed).
Running out of quota becomes a state rather than an error. The Claude
driver recognises its dialect's sentence -- `Claude AI usage limit
reached|1788546972` -- and reports `LimitReached` with the reset time it
gave; nothing above a driver matches on a string. The transcript draws it
as a divider, like a clear or a compaction.
The schedule is a plan to *ask*, never a plan to send. Both reset times
available are untrustworthy in the direction that matters -- the dialect's
is written when the turn fails, the endpoint's moves when the window does
-- so the wait ends in a question to the usage meter, and only `ok` with
no window at 100% sends anything. A window still spent reschedules to its
own reset time, which is what makes a limit that lifts late wait longer
and one that lifts early resume sooner. A meter that cannot be asked is a
longer wait too, never a send. A day after the limit was hit the wait
gives up and says so in the transcript, so a machine that can never be
asked is not retried for ever.
The schedule is persisted on the session: a five-hour window outlasts a
backend restart, and a wait forgotten across one never comes back.
Driven end to end with echo, never a real account: `/limit [minutes]`
reports the same event a real driver does and `/usage` sets what the meter
answers, deliberately separate so the two can disagree. The wait moved
from the dialect's two minutes to the meter's seven when the meter changed
its mind, and the message went out on the first check after the meter came
back under the limit.
Also makes the settings dialog scrollable, which these two controls made
necessary: at a 1.5x system font it clipped the last of them with nothing
on screen to say so.

`Config::default_effort` is what a session starts at when nothing chose one,
applied in `spawn_session` rather than filled in by the spawn screen so it
holds for an import and a bare API call too. It is set by the spawn screen's
own picker, whose label says so: one control, where new sessions are made,
rather than a settings page for a single value. Not on a provider, because
providers are discovered and the next rediscovery would erase it; not on the
phone, because a second device would then spawn at a level nobody there
chose. `GET`/`POST /defaults` carry it as a struct, so the permission mode --
still hardcoded to `auto` on the spawn screen -- can move there later without
a second route.
Only drivers that read a level are given one: an echo session was storing a
`--effort` it never passes to anything, which is a config file answering a
question about itself wrongly.
Separately, `AGENTS.md` is 35 KB sent with every request in this repo, and 12
KB of it was rigs and reference measurements that only matter once you are
running one. Those are the `ai-app-rigs` skill now -- the same text, still the
only copy, read when the work touches it. 35,198 -> 20,813 chars.
Verified on the emulator against the sandbox: the spawn screen pre-fills from
the server, picking `low` spawned a session at `low` and left `/defaults` set
to it, and an echo session spawned afterwards took no level at all.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Output is about an eighth of what a session costs and thinking is nearly
all of it -- prose is ~1.5% of output tokens, measured over 27,015 requests
of this account's own transcripts -- so the level is the largest saving
available short of shortening the conversation itself.
Shaped like the working directory rather than like the model: the CLI's
only two setting control requests are `set_model` and `set_permission_mode`
(checked against the 2.1.258 binary), so `--effort` is read when the process
launches and cannot be asked of a running one. `set_session_effort` records
the level and stops the process; the next message or Start launches one that
has it. That is also why the picker is in the session settings dialog beside
Move, and not on the bar beside the model and the mode, which take effect
mid-turn.
`None` is a level in its own right -- the CLI's own default -- so the picker
can return to it, and a blank is normalized to it at the boundary rather
than stored as a level the CLI would reject.
Offered only where it means something: `DriverKind::takes_effort` reports
the capability and the phone leaves the row out entirely, rather than the
session-type branch this app does not have anywhere else. A llama session
would otherwise get a control whose only effect is stopping its process.
Verified on the emulator against the sandbox's fake CLI: the picker sets it,
the server reports it, and an echo session's dialog is unchanged.

The rate-limit bar answered a question about an account, and picked the
answer by machine. One machine runs echo, the Claude CLI and a local
model side by side, so every echo session on it drew the CLI's five-hour
window: a quota that session cannot spend and could never run down. A
session now names its meter (`usageProvider`, from
`DriverKind::usage_provider`, which `usage::providers_for` reads too so
the two lists cannot disagree), and the phone matches on machine *and*
provider. Nothing meters echo or llama, and nothing at all is drawn --
including while the first fetch is out, since "checking" under a session
that turns out to meter nothing is a row the screen then withdraws.
Echo gets a meter it can be *told* about instead: `/usage 42`,
`/usage 95 20`, `/usage 42 never`, `/usage notloggedin`,
`/usage unreachable`, `/usage failed`, `/usage off`. Those states cost
real quota to arrange, which is why none of them had been looked at.
And llama.cpp runs wherever a setup says, which was the last of phase 5.
`Transport::reserve_port` is the second half of what a transport is --
"run this" plus "reach this port" -- returning the port the server binds
there and the port that reaches it here, and `Launch::reaching` puts the
`-L` tunnel on the connection that already carries the command. Three
things that came out of building it:
- A forwarded launch gets a pty and every other one keeps `-T`. Killing
the ssh client ends a CLI by closing the stdin it reads; llama-server
never reads its stdin, so the same kill left it running on the far
machine with the model loaded -- one orphan per stopped session.
- The model is looked for on the machine that will serve it, at that
machine's own models directory, so `GET /setups/{id}/models` is what
the spawn screen offers rather than the backend's own downloads.
- The readiness poll watches the process, not only the port: a model
that will not load exits in a second and would otherwise have been
reported as "gave up after 300s". The failure carries the log's tail.
Exercised end to end against this VM over ssh to itself: spawn, load,
answer, outlive a backend restart, be adopted, answer again, and stop --
with both the ssh client and the far llama-server gone afterwards. The
local path, the Claude bar and the spawn screen checked on the emulator.

The markdown had accumulated a lot that was stale rather than wrong.
PLAN.md still described pi as the llama.cpp harness, a refcounted
LlamaServerManager, and a providers-by-hosts cross-product, all of which
were superseded or never built; it also carried a second copy of the HTTP
table that routes.rs owns. EXPLORER.md and TRANSCRIPT_CACHE.md held
implementation checklists for work that has since landed. AGENTS.md
restated most of PLAN.md's design instead of being the working-notes
layer it says it is. 3225 lines of markdown to 2180, with the stale
sections gone rather than reworded.
On the server, comments explaining what the code already says are out and
the ones recording a constraint, a measurement or an incident are kept but
cut to a few lines each: 5504 comment lines to 4586.
Four doc comments in session/mod.rs, and one each in process.rs and
usage.rs, had drifted onto the item above the one they describe --
functions were reordered without them, so `stop_session`'s doc sat on
`set_session_cwd`, `stat_of`'s on `struct Stat`, and `UsageMonitor`'s on
`type Cached`. Each is back on its own item.
routes.rs's module table also claimed later phases would add `/hosts`,
which setups replaced.
cargo test (127 passed), clippy --all-targets and fmt are clean.

Reopening a session downloaded the conversation again, every time, over
the tunnel. It now draws from a copy of what the server has already sent
and asks for one event to check that copy is still current.
Per session, under cacheDir, the server's own event lines in chunks named
for the range they cover -- so a coalesced page, whose lines do not say
what they cover, still records it. Only the contiguous run ending at the
newest chunk is served; a gap is closed by paging through it, bounded by
`after` on /transcript so the page stops where the phone's copy starts
and can therefore be kept. Nothing is derived and stored: rows are a
rendering, and a cache of them would need throwing away on every change
to the fold.
Nothing here is load-bearing. Missing, evicted, damaged or unwritable all
degrade to the cold open this screen did before, and the check before the
stream resumes -- one request, one event -- is what stops a replaced or
truncated file being spliced onto a copy of a different conversation.
What that check cannot see, a line changed mid-file with the tail intact,
is what Reload in session settings is for.
Measured on the emulator against ui-sandbox, on a 505-event session:
reopening it costs one request for one event, including scrolling the
whole conversation back; a cold open is two requests and 100 events. A
reset after falling 300 behind fetched the gap as four coalesced rows
rather than re-fetching 104 events and discarding them. Every chunk was
checked line by line against what the server says for the range its name
claims, across the reset and the gap-fill.
transcript-bench.sh, same viewport content and gestures, before and
after: p50 16.9ms both, p90 25.6 -> 23.2ms, p99 33.5 -> 36.7ms, and the
transcript's own draw accounting 0.33ms -> 0.32ms with place 0.31ms
either way. Within the emulator's noise, which is what a cache must be:
it changes what is fetched, not what is drawn.
Building it also found that the server handed out the same transcript
line two different ways. serde_json's default float parser is not
correctly rounded, so a ts written as ...0757 came back from /transcript
as ...0755 while the SSE stream sent the original -- invisible on screen,
since a ts is drawn as a relative time, and visible here only because the
cache compares a line it holds against the server's answer. Fixed with
float_roundtrip, with a test that fails the moment it is dropped.

The first half of EXPLORER.md: server/src/files.rs, which lists a
directory, reads a file, writes one, and creates a file or a directory on
whichever machine a setup names.
Each operation is one small POSIX script run through `Transport`, the way
the import listing and the usage fetch already ask a machine a question,
so the local and the ssh case are one implementation rather than two that
drift. The path crosses as a positional argument and never as script
text; `PATH_PRELUDE` is the one line that gives a leading `~` its
meaning, because a shell expands a tilde in text and not in an argument,
and it is the far machine's home that has to answer.
A read has four answers -- text, binary, tooBig, or the machine's own
error -- because a binary file drawn as text and a big one cut off
silently are both wrong in ways the reader cannot see. A write carries
the sha256 the read reported and is refused with a 409 when the file has
moved on, which is what happens whenever an agent is editing the file
somebody is reading.
`Transport::capture_with_input` is the one description of "run this
there, with this on stdin", and `ship_attachment` moves onto it rather
than assembling a second ssh invocation of its own. It is also the only
capture that hands back the exit status, which is how the write says
"this is not the file you read" without that answer looking like a
failure.
Exercised on both transports against the sandbox -- ssh to this VM with a
throwaway key, since the quoting and the stdin path are what that proves
-- including a filename with an apostrophe, one with a tab, an unreadable
file, a binary one, one over the limit, and the 409.

Uploads no longer sit whole in memory anywhere: the phone writes the
multipart body chunked as it reads the picked file, and the server writes
each chunk to a `.part` file under the session and renames it when whole.
The per-request cap is 4 GB and bounds disk, not memory.
A file attached to a session on another machine is copied there in the
same request: one ssh invocation takes the bytes on stdin into the
setup's `attachmentsDir` (new, optional, on the machine form and in the
config), else the session's cwd, else the login home, and answers with
`pwd -P`, which is recorded beside the file as `<name>.remote` and is the
path the driver tells the CLI. A failed copy fails the upload and says
why, so no message ever names a file that is not there. The host keeps
its copy so transcripts can reference and fetch it. Measured against the
Gentoo test guest: a 40 MB file shared from the phone arrived there byte
for byte. The tilde in that setting is the remote home, so it is not
expanded on the server the way other setup paths are.
TRANSCRIPT_RENDERING.md records the week of transcript work -- the
measurements behind each decision, the harness, what was rejected, and
what to do next -- so a new session can start from it.

Attachments were images only. Now any file can be attached: from the file
chooser behind the "+" menu, or from Android's share sheet, which the app
is now in. An image still goes to the model as a picture; anything else is
stored under its own name (`<hex>-<name>`, cleaned by `safe_file_name`)
and the Claude driver ends the message with `Attached file: /abs/path`,
since the CLI reads files by path and a model cannot be shown a trace. The
user-message field is renamed `images` -> `attachments` on both sides,
with a serde alias reading the rows written before. A share arrives before
anyone has said which session it is for, so it is held in AppRoot with a
banner on the list until a session takes it; an open session takes it at
once. Unreadable shares are reported beside the composer, not thrown.
The tool card crashed the app when opened on a command holding a quoted
glob such as `-path '*/.git/*'`: highlights 1.1.0's shell lexer answers
`x '*/a/*'` with a span whose end is before its start, and AnnotatedString
refuses the range. Such spans are dropped; the library is the place for
the fix. The echo driver gains `/bash <command>` so a card with a given
command can be produced on the emulator.
ui-sandbox.sh's token salvage read the tokens block's close only at a line
start, ran past the compact `),],` the server writes, and copied `setups`
into the new config twice, which the server then refused.

The live Claude Code path only learns a turn was another agent's when
the turn ends -- the whole of the message arrives as an `origin` object
on the `result` -- so the note was appended after everything it caused,
and the transcript showed the answer above the question.
It cannot be recorded in place: by the time anyone knows, the reply is
already written, and the transcript is append-only. So the event carries
where it belongs instead. `PeerMessage` gains `turnStart`, the seq of
the status that opened its turn, stamped by the pump -- the only thing
that knows a seq and the only thing that sees every driver's turns. The
phone gives the note that seq, so it sorts into place rather than being
drawn out of order at the end. A status draws no row, so there is
nothing for it to collide with and the list stays sorted, which the
scroll anchor and paging both depend on.
Absent where there is nothing to correct: a message replayed out of a
session file by `import` is already in the right place, and one that
opened no turn has no turn to sit above. Both stay where they arrive.
The echo driver gets `/peer-turn` for the live shape, beside `/peer` for
the in-place one. Verified on the emulator both ways, live and on
replay, plus an ordinary `/tools` turn to confirm the run grouping the
insertion cuts through is unaffected.

`POST /sessions/{id}/cwd`, behind a field in the session settings dialog. A
working directory is settled when the process is spawned -- the CLI is
launched with it as its cwd and there is no control request that changes one
-- so this records the new one and ends the process that is in the old one.
It does not start a replacement, and the field says so in a line beside it:
a session with no process starts on the next message or on Start, which is
this app's rule for that everywhere else, and "usually restarts" is a worse
control than "always stops".
The path is checked against the session's own machine and refused if it is
not there. The spawn path corrects instead of refusing, because it is
resuming a directory the *machine* recorded and that can be gone through
nobody's fault; a path somebody has just typed is different, and a mistyped
one accepted here would surface much later as a session that would not
start, with nothing pointing at the typo. The refusal names the machine and
the path, and is drawn under the field it is about.
Nothing of Claude Code's own is moved, and that is measured rather than
assumed: on CLI 2.1.237, `claude --resume <id>` finds a session from any
working directory -- an id that does not exist answers "No conversation
found with session ID", and a real one resumed from an unrelated directory
did not. So the conversation continues in the new place with nothing
relocated. Doing otherwise would mean reproducing a rule this app cannot
see the whole of; PLAN.md records what that rule is, for whoever tries.
Found while checking it: `SessionInfo.cwd` came from the snapshot a session
launched with, so a moved session went on reporting its *old* directory for
as long as its process lived -- a dialog showing a directory the next launch
would not use, with nothing saying so. It is read from the config where the
row is built now, the same way `setup_name` already was, and for the reason
already written above `setup_name`: only the manager holds the config, and
both of these change under a running session.
Checked end to end on the emulator against a session whose process really
does take a cwd: /proc said /tmp/cwd-a before and /tmp/cwd-b after, the
dialog showed the new path immediately rather than after a restart, and a
directory that is not there and a relative path were both refused with the
session left exactly as it was.
Peer messages were only ever produced by the *import* path, reading them out
of the CLI's own session file. A message another agent sent to a session
this server was driving appeared nowhere, so the session started working on
something nobody on the phone had asked for and there was nothing on screen
to explain it.
Measured rather than guessed, because the obvious place to look for it is
empty: a real cross-session message sent to a real `--input-format
stream-json` session on CLI 2.1.237 produces **no `user` record**, and
nothing in the partial-message stream mentions it either. The whole of it
arrives as an `origin` object on the turn's `result`, in exactly the shape
the session file records -- so `import::peer_message` now reads both, one
function for one wire format. Two copies would drift the first time a field
is renamed, and the half that drifted would go on producing nothing, which
is indistinguishable from nobody having sent anything.
The cost is the position: the note lands after the reply it caused rather
than above it, because at no earlier point in the turn does the CLI say why
the turn started. Taken deliberately over the alternative -- a second reader
tailing the CLI's own session file for the one record stdout does not carry,
which is two sources of truth for one conversation and a poll per live
session. Recorded in PLAN.md so that if the CLI ever announces the injection
where it happens, the next reader knows to move it there.
Both halves tested: the real record shape, and an ordinary result carrying
no `origin` -- which is the half that decides whether the check is a check.
Four ordinary results on a real session's stdout had none between them.
A message written into the tail of a turn is read the moment that turn's
`result` lands: the session reports idle and is running again in the same
breath. The phone that sent it got "finished" in between -- seconds before
anything it asked for had been done, which is the notification arriving to
say the opposite of what is happening.
`notification_for` now takes how many messages the session has been given
and not started reading, and a turn ending with any of them waiting is not
an ending. The count is kept in `pump`, from the recorded events, because
that is the one place that sees all of them in transcript order: a
`messageQueued` up, and the `userMessage` that resolves it or a
`messageDropped` down. Asking the driver instead would answer about the
moment the question was asked rather than the moment the status was
written, which is the same class of mistake as reading a session's status
to decide what a queue contains.
It deliberately does not suppress *awaiting input*. A question is worth
interrupting somebody for whatever is queued behind it -- the queue is
precisely what will not move until it is answered.
Tested both halves: the decision on the number, and the number itself,
where an echo turn that reads its queued message before going idle still
announces its finish. That last is the case a suppression written slightly
wrong silences, and it is the common one.
Two things a reader could not do to what is on screen.
**Selection.** Nothing in the transcript was selectable at all, so a
command, a path or an error message could be read and not copied. One
`SelectionContainer` around the whole list rather than one per row: a
transcript is one body of text to a reader, and a selection has to be able
to run from a reply into the tool output under it. Per row it also could
not, and whatever was drawn without a container would have been silently
unselectable -- a state nothing on screen reports. Rows keep their tap
handlers; checked on the emulator that expanding a tool call, scrolling and
flinging are all unaffected, since a selection is a long press.
**Taking a message back.** A message sent into a running turn sits as a
bubble waiting to be read, and there was no way to change your mind: it is
tappable now, and the server answers `POST /sessions/{id}/unqueue`.
The answer has three states, and the middle one is the point. Claude's
driver writes a steer into the CLI's stdin the instant it arrives -- that
is what makes it reach the model at the next tool boundary rather than at
the end of the turn, and it was measured -- so the line is already gone and
`AlreadySent` is the only honest answer it can give. Holding the write
until a boundary would make the drop real and cost a steer one model call,
which is the latency the immediate write exists to remove; rejected on that
trade, with the reasoning in PLAN.md. The refusal is drawn on the bubble
that was pressed rather than in the error row under the header, a screen
away from it.
Where a driver really does hold its queue -- echo today -- the message goes
for good, and it goes as an `Event::MessageDropped` rather than as a return
value: every device watching the session loses the bubble, and a phone that
reconnects and replays the `messageQueued` does not put back one that was
cancelled with nothing left to resolve it.
A Rust backend that owns the sessions and an Android app that reads them.
The server spawns and adopts CLI processes, normalises everything they emit
into one event model, keeps the transcript, and serves it over pinned TLS on
a WireGuard interface; the phone streams that, replies, sends images, and
imports conversations the machine already has.
`AGENTS.md` is the working guide -- what runs where, what has been measured,
and the faults that were expensive to find. `PLAN.md` is the design record.
History before this point was squashed away. It was a personal project's
running commentary and carried a name and a couple of machine paths that
have no business in a public repository; the tree is what mattered and the
tree is here.
