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.

modes: [release, debug], release first as the default; build-apk.sh
already takes the mode as its last argument, which is how Dev Updater
passes it. enroll: goes through server/enroll-link.sh rather than the
binary directly, because the command is handed the app's mode too and
because the server may have been built in either profile -- the wrapper
ignores the word and takes whichever ai-server exists, release first.

Prints the enrollment URI, one line on stdout, and exits; the running
server adopts the token the first time that device presents it, via the
spool wg-app-link's enroll module now provides (submodule bumped to
d35c880). This is the server half of enrolling through Dev Updater: its
coming per-component Enroll button runs this command and opens whatever
it prints on the phone, which is what a reinstall -- a signing change, a
new phone -- needs when nobody is at the terminal the QR is printed on.
Verified against the sandbox server: minted while it ran, first request
with the token served and the token moved into config.ron, spool empty,
second request served as an ordinary token. 108 tests, clippy clean.

The scroll-up freeze-then-skip was the history pager fighting the transcript's
own storage. A streamed reply is stored one token per event -- hundreds of
AssistantText events for one message -- but a page was counted in events, so
on a delta-heavy conversation a page was a fraction of one row: the opening
80-event load was less than a screen, "scroll up a bit" hit the unloaded
boundary at once, and each page the client did fetch cost a 400-event fold
(hundreds of thousands of list copies) that landed as one jarring insertion.
The server now joins each run of consecutive AssistantText deltas into the one
event the client's fold makes of it, and counts a page's limit in these
coalesced rows -- so a page is a page of the screen whatever the delta density.
Measured against a 3,500-event / 100-row echo session on the emulator: a raw
limit-20 page returns 20 tokens of one reply; the coalesced limit-20 returns
five whole replies. Scrolling the whole thing showed waited p99 51.7ms -> 0.6ms
and the worst whole-transcript measure 59ms -> ~0, with the client folding ~100
row-events instead of 3,500 token-events. No duplicate keys; the first reply
still reconstructs whole from token zero, so healSplitMessage welds the raw
newest window to the coalesced older pages exactly as before.
Coalescing is opt-in per request (`?coalesce=true`) and applied only to older
pages (`before` set): the newest window keeps real seqs because the live stream
resumes from the newest seq the phone applied, and a coalesced newest event
would hide the deltas after its first seq and replay them. The anchor-restore
path also stays raw -- it counts events to reach a known seq, which a page
measured in rows cannot do -- so HISTORY_PAGE is now rows while the restore
span and its cushion stay in events.
Also: ui-sandbox.sh gains a `keep` verb that restarts the server without wiping
sessions, so a fixture that costs minutes to build (a long delta-heavy
transcript) survives a server rebuild.

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.

Replaces the connection throttle from the previous commit, which was a
workaround: it made a batch slower without changing that N sessions
meant N ssh connections, and the cap it picked was a guess at somebody
else's sshd config.
The batch now goes out as a single invocation. import::delete takes the
whole list, the remote script loops over the ids and prints one
`<id>\t<state>` line each, and the route settles every row from its own
line. So a batch of any size is one connection and cannot exceed
MaxStartups however many rows are selected -- and it is faster, since
it stopped paying a handshake per session.
Each id still reports on its own: deleted, missing, or failed, kept
apart because only "failed" is worth retrying. Ids the machine never
mentioned -- a connection that dropped part-way -- are reported as
unknown rather than defaulting to either answer, and a malformed id
fails only itself.
Verified end-to-end against a fake ssh that counts connections: a
9-session batch used one, every row settled, both copies of a session
recorded under two project directories went, and the id that was not
there failed with a message saying so rather than a connection error.

Deleting or importing several Claude Code sessions fired one ssh
process per item, all in the same tick. A large enough batch opened
more connections than the remote sshd's default MaxStartups tolerates
before it starts randomly refusing, so some rows failed with
"Connection closed by ... port 2222" -- not a real delete failure,
just too many handshakes landing at once.

`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.
A `Read` that returns an image is a row of one call, and the moment the
session makes its next call the two become a group -- which is a different
composable in a different part of the tree, so the old subtree goes and
everything it remembered goes with it. The full-screen viewer was inside
that subtree, so somebody looking at a screenshot was thrown back to the
transcript because the session carried on working. A page of history
landing does the same thing to the same row.
What is open is a property of the screen rather than of whichever row
happened to draw the thumbnail, so it is held there now and drawn beside
the other two dialogs. Nothing that happens to rows can reach it.
The cost is one fetch when it opens, since the thumbnail's decoded bitmap
belongs to a row this no longer goes through. Paid deliberately rather than
plumbed around: it is one request for a picture somebody asked to see, and
the viewer draws the same two empty states the thumbnail does -- still
coming, and never coming -- which it previously could not have, since it
only ever opened on a bitmap already in hand.
`/tools n gap` now puts a screenshot on its first call, so the case is
reproducible rather than argued about: that command already existed to make
a run *grow* while somebody watches, and the image is what made growing
matter. Checked on the emulator with `/tools 3 30` -- opened the image on
the lone call, and it was still open a minute later with the row by then
inside a group of three, and back returned to the transcript rather than
leaving the app.
`Queue::close` reports the messages a dead process never read -- they
reached no transcript, so that error is the only place they are ever
mentioned -- but it left each one drawn as a bubble waiting to be read, by
a session that no longer exists. Nothing would ever clear it: the
`UserMessage` that resolves a queued bubble is exactly what is not coming.
Seen on the emulator as a grey bubble sitting under its own error message,
still saying "tap to take it back", on a session reporting `exited`.
It now sends the `MessageDropped` the unqueue route introduced, one per
lost message, alongside the error. The error says what happened and the
drop is what ends it, which is the same division of labour as the rest of
this path.
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.
Resuming a Claude Code session from a different working directory makes the
CLI write a second transcript with the same id under that directory's
project folder. This machine has one: 160 KB under `-home-bob-repos-tdep-survey`
and a 614-byte stub under `-home-bob-repos-tdep`. Everything downstream
addresses a session by id -- `--resume` takes it, the delete glob resolves
it, the in-flight registry is keyed on it -- so two rows sharing an id are
two rows no operation can tell apart, and the phone keys its list on it, so
scrolling to them closed the app on Compose's duplicate-key throw.
The listing now keeps the copy with the most in it. Size rather than
recency, because the stub is often the newer of the two, and picking it
describes the session by the wrong size, the wrong cwd and the wrong title.
Deleting removes every copy rather than stopping at the first, which had
left the row to come back on the next listing after a delete that reported
success.
The phone's half is `uniqueItems`: every list keyed on a server-chosen id
goes through it, since none of them could rule the repeat out locally and a
data problem must not be able to close the app. Verified both ways against
the real duplicate -- the unguarded build reproduces the reported stack on
the same id, the guarded one scrolls the whole list.

The renderer draws every table cell at one line with an ellipsis, so most
of a table was unreadable on a phone -- and an elided cell looks exactly
like a short one, so nothing said anything had been cut. Cells now take as
many lines as they need and align to the top of the row. Width is the other
half: a column narrows to 136dp and no further, and past that the table
scrolls sideways rather than squeezing. 136 is the widest floor that still
fits three columns across a phone, measured rather than picked; four and up
scroll, which is the right answer for genuinely too many columns.
The import screen used to send one request per selected row, so a handover
was only as atomic as the network: some rows started and the rest were
never asked for, and a row nobody asked for looks exactly like a row nobody
picked. `POST /setups/{id}/importable/delete` and `.../import` now take the
whole list, and every id is registered as in flight before the 202 goes
back. Only the registering is atomic -- the work settles per row, since six
deletes that all roll back together is not something a filesystem offers.
The echo driver grows `/table N`, with cells long enough to have been
truncated: a fixture of tidy one-word values renders fine whether or not
the bug is there.

Leaving the import screen used to cancel the batch it had started: the
request was the work, so the coroutine that owned it died with the screen
and coming back showed no sign anything had happened. A half-imported
session is the expensive kind of missing -- the row is back looking
untouched, and taking it again is the second `--resume` the import path
exists to prevent.
So the work runs on the server now. Delete and a new per-session import both
answer 202 and spawn the work, and `session::pending` is the record of it:
what is running, and how the last attempt failed. The phone reads that two
ways and needs both. Every row of the listing carries `pending` and `error`,
which is what a phone that was asleep, out of range or freshly opened has to
go on; `GET /setups/{id}/importable/events` streams the changes, which is
what makes a screen somebody is watching change by itself.
Neither alone is enough, and that is not theoretical. A broadcast has no
memory, so an operation that started and finished while the stream was still
connecting was one nothing would ever be said about -- with responses held
back far enough to make it visible, one row of a pair of deletes cleared and
the other sat on "waiting" for good. The screen now asks again after a
handover when anything still looks outstanding, and takes its row states
from that answer rather than from what it remembers.
The single tap still waits, because "take me to it" needs the session that
was made and 202 does not carry one. Both paths go through the same `spawn`
so they cannot drift about what importing means.
Resolving one importable session no longer lists every one of them:
`import::find` is the same script with one glob narrower, which takes the
import seed off the 3.7-second full scan that `delete` came off earlier.
The SSE connection and its framing are now `Sse`, shared with the session
transcript stream rather than written a second time.
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.
