irisandClaude Opus 5 6119926a4d Start the process for a rename too -- the CLI keeps its own name
The last commit left renaming out on the grounds that the name is
persisted and listed whether or not a process hears about it. That was
wrong, and Iris said so: Claude Code keeps its own copy of the name,
that copy is what its session picker shows and what other agents read
when they list sessions, and a session is only ever *given* a name at
birth -- every later start is a `--resume`, which passes no `--name`.
So a rename that reached no process left the two lists disagreeing
permanently, with this app's the only one that had moved. The cost of a
resume buys the one thing renaming is for.

It stays `rename_session` rather than becoming a command like the rest,
because the name is persisted and listed as well as forwarded and that
is one operation. The save happens first and the lock is dropped before
the telling, so a failure to start reports that the telling failed
rather than the rename, which by then has already happened.

`LiveSession::run_command` went with it. It read `shared.status` and
that read is exactly what a just-started session cannot be judged by, so
every caller now goes through the manager -- which is also what the four
tests that used it were standing in for.

Verified against a stand-in CLI that echoes its stdin: a session
reporting `exited` was renamed, the process started with `--resume`, and
the CLI received `/rename after the restart` on stdin. The list shows
the new name and the session reports idle.

irisandClaude Opus 5 1a132b4de3 Start a stopped session's process for a command too
Same reasoning as the message path a commit ago, and the same objection
to leaving it out: a command is something somebody asked the session to
do, and answering "its process has exited" hands back the work of
starting one. `/compact` on a stopped session is the case that shows it
-- what is being asked for is exactly what a stopped session needs
before it is useful again.

`POST /sessions/{id}/command` and `/compact` now go through
`SessionManager::run_command`. A rename is deliberately not one of them:
it is persisted and listed whether or not a process ever hears about it,
so starting a CLI to tell it a name would be spending a resume on
nothing. It stays a forward to a process that happens to be there.

A command needs one thing a message did not. `Commands::submit` refuses
on `Exited`, and a driver that has just started a process announces
`Idle` through the sink rather than writing it -- so a command judged
against the session's own status would be refused by the word the start
had just replaced, in a window narrow enough that only a test reliably
hits it. `start_if_exited` returning `Exited` is what says a process was
started, so the status the command is judged against comes from there
rather than from a re-read the pump may not have caught up with. The
test fails without it.

`LiveSession::compact` went with this: `/compact` the route and
"/compact" the typed command were two ways to the same command, and now
there is one.

Verified over the API against a stand-in CLI: with the session reporting
`exited`, both `/clear` and `POST /compact` started the process and were
delivered -- transcript order `idle`, `commandSent`, `running`, `idle`,
with no "this session's process has exited" anywhere.

irisandClaude Opus 5 4a122f7b25 Start a stopped session's process when a message is sent to it
Refusing was work handed back: read the status word, find the other
button, press it, type the message again. Sending plainly means "do this
now", and `--resume` puts the new process on the same conversation, so
nothing about the message changes -- only whether there was anything
there to read it.

`POST /sessions/{id}/message` now goes through the manager, which starts
a process first when the session is known to have exited. Only on
`exited`: `unknown` has a process that may well be reading its fifo, and
starting a second CLI on that guess is the fault `session::process`
exists to prevent, so the message goes to the driver as it always did.

The Start button and this ask one function, `start_if_exited`, and want
opposite answers from it -- "there is already a process" is a refusal
worth showing to somebody who pressed Start, and nothing at all to a
message being sent. Deciding it in one place under the one write lock is
also what keeps two requests that arrive together from starting two
CLIs.

Verified over the API and on the emulator: with the session reporting
`exited` and the composer showing a play button, typing a message and
pressing Send started the process, delivered the message and ran the
turn -- transcript order `idle`, `userMessage`, `running`, `idle` -- and
the button became a stop.

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 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.

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.

75 tests, clippy and rustfmt clean; ktfmt, compileDebugKotlin and
lintDebug 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.

70 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.

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.

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.

irisandClaude Opus 5 6166b1f626 State the deny-unknown-fields rule where it governs all the bodies
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
request body knows it is expected to carry the attribute too.

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 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 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 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

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.

iris dcb158ee44 Fetch the transcript instead of replaying it one event at a time
**The five seconds of loading top-down.** Opening a session subscribed to
the event stream from sequence zero, so the backlog arrived as one SSE
frame per event -- 864 of them for an imported conversation, rendered as
they landed. That is not a slow list; it is a conversation being replayed
at network speed, and it looks like loading from the top because it is.

The newest page now comes as one request, and the stream starts from where
that page ended, carrying live events only -- which is what a stream is
good at. Scrolling back fetches the page before it, so history costs
something only when somebody actually reads it. 80 events instead of 864,
and the first frame is already the end of the conversation.

I had called this fixed after anchoring the list at the bottom, on the
strength of an emulator on the same machine as the server. That test could
not have shown the problem: the whole backlog arrived in one frame's worth
of time over loopback. Iris's phone, over a tunnel, took five seconds.

**Send disappearing while running.** It was never conditional -- the row
simply ran out of width. A Row hands out intrinsic widths in order and
clips the overflow, so when Stop appeared the pickers I had added pushed
Send off the screen: the app's central control, gone at exactly the moment
the app is most in use. The settings now share what is left after the
actions have taken what they need.

While a turn is in flight the button says **Queue**, because that is what
sending then does -- the message is injected at the next tool boundary
rather than starting a turn of its own. The backend has always done this;
the button was describing something else.

**And the model picker no longer dismisses the keyboard**, which it did by
taking focus. Changing the model mid-sentence is an aside, not a departure
from what you were typing.

Verified on the 864-event import: at the newest message within a second,
history paging back continuously past the first page, and Stop beside
Queue while running.

iris 3f8805a610 Say which kind of delete this is, and stop offering what is already open
**Deleting was one word for two different acts.** An imported session's
real transcript belongs to Claude Code and outlives anything this app
does, so removing it here undoes a view. A session started here has no
copy anywhere, and removing it ends the conversation. The dialog warned
"this can't be undone" of both, which makes the warning worthless on the
one where it is true -- and frightening on the one where it is not, since
what it actually deletes is a cache of a conversation still sitting on
the machine.

Sessions now report whether they were imported, and the dialog says which
act this is. No new mechanism: the soft delete already existed, it was
just indistinguishable from the hard one.

**And a session already open here is no longer offered for import.**
Importing one twice would leave two `--resume` processes appending to the
same transcript, each seeing the other's writes as work done elsewhere and
replaying them -- both sessions then showing a conversation neither is
having. The route refuses it as well, so the rule holds for anything not
going through the app.

Left out of the list rather than shown and disabled. The usual argument
says absence is ambiguous, and it is wrong here: an imported session has
not disappeared, it has moved to the session list, which is where it now
belongs. Absence means "already somewhere you can reach it". Deleting the
app's copy puts it straight back -- verified: 68 offered, 67 after
importing one, 68 again after the soft delete, which is also the clearest
demonstration that a soft delete keeps the conversation.
2026-08-28 22:53:42 -04:00
iris a9ea84c96c 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.

iris 233689ced6 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.
2026-08-28 22:08:43 -04:00
iris 6bbc829a3e 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.
2026-08-28 21:45:14 -04:00
irisandClaude Opus 5 19e3531c5d Add, rename and remove machines from the phone -- without letting it name commands
The gap PLAN.md recorded: setups were readable but only hand-editable, so
adding a machine meant a shell on the backend.

**The design decision, made with Bryan, is that the phone never composes a
command.** A setup carries providers, and a provider carries something to
run -- so a route that accepted a command from the request body would make
the enrolled token arbitrary code execution on every machine a setup names,
and the transport already reaches those over ssh. Instead the phone sends
connection details, and the server asks the machine itself what it has:
one `command -v` round trip per setup, matched against a table of the
drivers this server knows. The phone's authority is "add this machine",
never "run this".

Worth recording that this was a narrower change than it first appeared: the
token could already run anything on the backend, because the spawn screen
offers `bypassPermissions` with a free-text working directory. Discovery
does not close that door. What it does is keep the *list of what can run*
out of the phone's reach, and make adding a machine a thing you cannot get
wrong by typing.

It is also simply better to use. Nobody wants to type an absolute path on a
phone keyboard, and a machine whose binaries have moved answers correctly
on the next probe. The cost is that a program somewhere unusual is
invisible -- `command -v` follows PATH under a non-interactive ssh session,
which is not the PATH a person sees when they log in. That is the trade,
and the escape hatch is editing config.ron on the backend, which is exactly
the authority the phone is not being given.

Setups now have an **id separate from their label**, so renaming a machine
does not orphan the sessions that name it; a session stores the id, and
every row resolves the current label when it is built. `POST /setups/probe`
tries a machine without saving anything, so a wrong address or an
unauthorised key is caught while the form that caused it is still on
screen. Deleting is refused while sessions still run there, and says which
ones rather than cascading.

Every mutation goes through one `update`: clone, apply, save, then commit,
so a failed write leaves the previous state intact and reports why.

Verified against a running server, including a real ssh machine (this VM,
via a throwaway loopback key since removed): probing here found echo and
claude-cli; probing over ssh found claude-cli and correctly no echo, which
runs in-process and exists only where this server does; an unreachable
machine came back with ssh's own words ("connect to host ... Connection
timed out"); adding derived the id `loopback-vm` from "loopback vm";
renaming kept the id; deleting was refused while a session used it, naming
it, and succeeded once nothing did.

irisandClaude Opus 5 ecac404fd4 A setup is a machine, and it carries what that machine can run
Providers and hosts were two independent lists, and a session named one of
each. They were never independent: a provider only exists on a machine
where that program is installed, so the spawn screen offered the whole
cross-product, including "the Claude CLI on the box that hasn't got it".
The picker could not know, because nothing in the model said.

Now a setup is a machine -- optional ssh, plus the providers it has -- and
spawning is two choices in order: pick a setup, then one of its providers.
The impossible pairs stop being expressible rather than being validated
against. Provider names are unique within a setup and only within one, so
two machines can each have a `claude-cli`, which was previously either a
name collision or two entries called things like "claude" and "claude on
the vm".

It also settles the "Run on" problem properly. That control was offered for
every provider but honoured only by the Claude driver -- an echo session
sent to a host ran locally and said otherwise. There is no such control
now: the machine is chosen first, and echo is a provider of the setup with
no ssh, where it belongs, since it runs in-process and has no transport to
cross.

The built-in echo provider is gone as a concept. It used to be conjured at
read time and never written to the file, which meant a provider nobody
could see or edit; it is now seeded into the config on first run alongside
claude-cli. What the file says is what there is, and deleting it is a
choice rather than a state to be repaired.

A config in the old shape is refused with instructions rather than loaded.
`Config` defaults unknown fields away, so `providers:` and `hosts:` would
otherwise have vanished into an empty config that was then seeded over --
a migration nobody would notice until their setups were gone.

Verified against a running server and on the emulator: a fresh install
seeds "this machine" with echo and claude-cli and the file reads cleanly;
a two-setup config lists both with their own providers; spawning on a
setup works and the session row names it; asking for a provider a setup
lacks says which it offers, and an unknown setup says which exist. On the
phone, selecting "dev vm" narrows the provider chips to that machine's one
and shows its address.

irisandClaude Opus 5 3deeffd1e7 Run GGUF models through llama-server, and stop orphaning them
The second half of the llama.cpp work: a session can now name a downloaded
model and talk to it. `llama-server` is spawned through the same transport
as any other driver, polled until the model is loaded, then driven over its
OpenAI-compatible streaming endpoint and translated into the same events
the Claude driver emits -- so the transcript, the SSE stream and the phone
need to know nothing new.

**The conversation is rebuilt from the transcript, not held in the driver.**
llama-server is stateless between requests, so the whole history goes with
every one, and the obvious place to keep it is a Vec in the driver. That
fails the requirement: memory in a driver is invisible to a second device
and gone on restart, and this app is meant to work across devices. Reading
it back also means the model is prompted with exactly what the phone was
shown -- including a reply that was interrupted half way, which is in the
transcript because the deltas were already emitted.

That leaves the Claude driver as the odd one out rather than this one: the
CLI's memory of a conversation is a cache in front of the same transcript,
not a second truth. Said so at the top of llama.rs, because it is the sort
of inconsistency that gets "fixed" in the wrong direction.

Session settings arrive as a driver-interpreted `params` map rather than
new typed fields, so the shared schema does not grow one dialect's
vocabulary. Context size, gpu layers and threads become server flags;
temperature and the rest ride on each request, so changing them need not
reload a model.

**Also fixes an orphan this feature would have created.** Drivers set
kill_on_drop, which covers a session being deleted -- but nothing drops on
the way out of a SIGTERM, so signalling the server left its children
running. For the Claude CLI that is untidy; for a llama-server holding a
model it is gigabytes belonging to nobody. The server now stops its
sessions on SIGTERM and SIGINT. Found by killing a test server and noticing
two 600 MB processes still resident.

Remote llama sessions are refused rather than half-working: the model is
reached over HTTP, and forwarding that port to an ssh host is the "reach
this port" operation the transport does not have yet.

Verified end to end against a real model: downloaded Qwen3-0.6B Q8_0
through the app's own download route, spawned a session on it, and held a
two-turn conversation -- "my favourite colour is teal" then "what is my
favourite colour?", answered "teal", which is the transcript replay doing
its job. Token counts arrive. An earlier attempt with the IQ2_XXS quant
produced fluent nonsense, which turned out to be the quantisation rather
than the pipeline: llama-cli produces the same from that file directly.
Four unit tests cover the fold and the path guard.

irisandClaude Opus 5 9d29776f02 Download GGUF models from HuggingFace, watchably
The first half of the llama.cpp work Bryan asked for: browse HuggingFace,
fetch a model, and see how far it has got from any device.

The design is dev-updater's build-progress shape with the four changes its
author recommended after living with it, since a model download is an hour
where a build is two minutes:

- **A run has an id.** Without one "not downloading" means three different
  things -- finished, never started, or someone else's run ended while you
  were away -- and over an hour that ambiguity is certain rather than
  theoretical. A device compares the run it was watching to the run
  reported now.
- **Outcomes outlive their run**, so a phone that was asleep at the moment
  of completion can still find out what happened.
- **Cancel exists.** Retrofitting cancellation into a blocking loop is
  miserable, and several gigabytes over someone's data plan is not
  something to have no answer for.
- **Progress is bytes, not a parsed marker.** We own the loop, so it counts
  directly; `total` is whatever Content-Length said and nothing else, and
  stays absent when the server sends none rather than becoming a bar drawn
  from a guess.

The download owns its own thread rather than the blocking pool, which
exists for short work. It resumes through HTTP Range, and trusts the 206
rather than the request -- a server that ignores Range answers 200 with the
whole file, and appending to that would corrupt it. `truncate(false)` on
the open is load-bearing for the same reason and says so.

Searching is proxied through the server rather than done from the phone,
because the app trusts exactly one certificate -- this one -- and the
machine that must do the downloading is also the one whose view of what
exists matters.

Verified against the real HuggingFace, not a mock: searched, listed a
repository's GGUFs, downloaded 234 MB with live byte progress, cancelled
mid-flight, confirmed the partial survived, restarted and watched it resume
at 162 MB rather than 0, and let it finish. The result's sha256 matches the
one HuggingFace publishes for that file, so the resume is byte-correct and
not merely the right length. llama.cpp then loaded it and ran inference.

irisandClaude Opus 5 c12ab7f098 Take rustfmt's defaults
The code was hand-formatted -- close to rustfmt's output but not it, mostly
in keeping chains and call arguments on one line where the formatter would
break them. That is a per-line decision every future change has to make
again, and reproducing it would mean a config whose only job is to preserve
how the code already looks.

So this is `cargo fmt` at its defaults, with no rustfmt.toml, which is
where the sibling dev-updater checkout already sits: it is clean at the
defaults today, so the two repos now agree on layout without either of them
configuring it.

Formatting only -- no behaviour, no renames, nothing reordered. Verified
after: cargo test (35 pass), cargo clippy --all-targets clean, cargo fmt
--check clean.

2026-08-28 03:13:36 -04:00
irisandClaude Opus 5 19de699bfa Follow dev-updater's own config to RON
The same move, for the same reason: this file is written and read by hand,
and JSON has no comments to say why a host is configured the way it is.
Both house rules come across with it, in config.rs's `format` module and
nowhere else -- a file is the *body* of the config, so no outer parentheses
and nothing indented for them, and `Some` is implicit, which is what makes
`skip_serializing_if` on every optional field load-bearing rather than
tidiness.

The switch is outright: there is no reader for the old format. That is
invisible everywhere except here, because this file holds the enrolled
token hashes -- starting empty leaves the phone unable to talk to the
server and looks, from the phone, like the config having been lost. So a
config.json left beside the new file is named in the log and left alone,
rather than read or deleted.

One wart, documented at DriverKind: the kebab-case spelling is the string
the phone compares against, so it stays, and the file pays for it with
`kind: r#claude-cli` -- a hyphen is not a RON identifier. Renaming the
variant would change what an already-installed build is talking to.

Verified: cargo test, cargo clippy --all-targets, and a real start against
a scratch state directory -- a hand-typed config with comments and a bare
`port: 2222` loads, and what the server writes back sits at column 0 with
no Some(...) in it.

irisandClaude Opus 5 99bcc341c1 Cleanup pass: one home for duplicated logic, stale comments out
Nothing behavioral except two status codes; mostly removing places where
the same rule was written down more than once and could drift.

- server/src/private.rs: the owner-only create/write helpers, which
  config.rs, certs.rs, and the session dirs each had their own copy of
  (certs.rs even duplicated the explanatory comment). One module owns the
  modes now, so the "nothing this server writes is readable by anyone
  else" property is checkable in one place.
- server/src/media.rs: the image media-type/extension table, which the
  four places that have to agree on it each spelled out separately --
  storing an upload, serving it back, building a content block, saving a
  produced image. The differing *defaults* stay at the call sites with
  the reasoning, since they genuinely differ by direction.
- routes.rs: a missing file was a 400 and an unreadable one a 400 with a
  hand-rolled log line; they are now 404 and Internal respectively.
  UnknownSession became NotFound, since it was the only 404-with-message.
- main.rs: xdg_dir takes the variable's value instead of reading the
  environment, which drops the unsafe set_var from its test and lets the
  test actually assert the relative-path rule.
- echo.rs had its own 4-byte hex generator beside session::random_hex.
- claude.rs: the two impl Translator blocks were one type's methods.
- Stale comments: phase-2 markers on shipped work, a permission-mode list
  that had drifted from the CLI's, "dev-updater" as the leaf certificate's
  fallback common name, a half-written sentence in build-apk.sh.
- App: the JSONArray walk written out in four fetchers, the four
  near-identical BackHandlers in AppRoot, and SessionScreen's inline
  fully-qualified names where the file otherwise imports.
- server/wg-test.log was committed by accident; *.log is ignored now, and
  the gitignore comments describe where state actually lives.
- PLAN.md's backend layout gains the new modules and drops hosts.rs for
  the ssh.rs that was built instead.

Verified: 35 server tests, clippy clean, app compiles warning-free, and a
scratch server driven over curl -- attachment upload/serve round-trip with
both a known and an unknown content type, the new 404s, transcript and
session-dir deletion, plus a real claude-cli session answering a prompt.

irisandClaude Fable 5 fff1fb49e8 Providers and hosts: what runs, and where, as independent choices
A session now names a provider (what: driver kind, command, models) and
optionally a host (where: an ssh target). Keeping them independent is
what the real setup needs -- the backend runs where the phone can reach
it, which isn't where the CLI is installed -- and it means any provider
can be sent to any host rather than a machine being baked into one.

The first provider is claude-cli, named for the CLI rather than bare
"claude", which would suggest the credit-billed API. A fresh config is
seeded with it so a new install has something to spawn and a worked
example to edit; echo stays a built-in provider needing no config.

ssh.rs builds the child process either way: locally, or `ssh -T` with
BatchMode and keepalives, every argument single-quoted for the remote
shell (a working directory that tries to close the quote and start a
command is covered by a test), and `exec` so dropping the connection
takes the CLI down instead of orphaning it.

App: the spawn screen reads /providers and /hosts instead of hardcoded
lists, so config changes need no rebuild. Chip rows are FlowRow, fixing
the reported bug where a row of models that didn't fit wrapped *inside*
each chip -- one letter of "haiku" per line -- rather than onto a second
line.

Verified: 29 tests, clippy clean; the same claude-cli provider run once
locally and once over ssh, with the remote one visibly in a different
environment; an unknown host name refused with the configured list; and
the spawn screen on the emulator showing server-driven providers, hosts,
and models that wrap.

irisandClaude Fable 5 3c97a5ef28 Phase 3: usage screen
GET /usage serves the numbers behind Claude Code's /usage, read with the
CLI's own stored OAuth credentials (nothing to configure). The endpoint
is undocumented, so parsing is defensive -- the generic limits[] array
becomes labeled window bars, unknown kinds surface under their raw name,
and any failure degrades to an 'unavailable' snapshot with the reason.
One UsageProvider per paid service behind a caching monitor that
enforces the >=180s minimum poll regardless of phone refreshes; no
background polling at all. ureq (rustls) does the outbound call, with
the process-level CryptoProvider now chosen explicitly in main -- ureq
brings ring while axum-server brings aws-lc-rs, and with both in the
graph rustls refuses to guess.

App: a Usage screen off the session list -- per-window bars colored by
utilization with relative reset times. Verified live: 74%/26%/16%
windows rendered against the real endpoint.

irisandClaude Fable 5 f2430671a2 Phase 2 complete: images both ways
Inbound: POST /sessions/{id}/attachments stores a picked photo under the
session; message attachmentIds become base64 image blocks in the
stream-json user message (verified live: an uploaded red PNG answered
"Red."). Outbound: image parts in tool results are decoded into the
session's files/ dir and referenced by Image events -- the transcript
stays lean -- and GET /sessions/{id}/files/{ref} serves them (verified
via the Read tool round-tripping the same PNG). The app grows an attach
button (system photo picker, upload-on-pick) and renders Image events
inline with an authenticated pinned fetch. Sent attachments are echoed
into the transcript as Image events so every device shows them.

Attachments and files are addressed under their session (a deviation
from PLAN.md's original bare /attachments -- recorded there) so their
lifecycle is the session directory's: deleting the session is still the
complete path out.

irisandClaude Fable 5 95d389e2b8 Phase 2 core: ClaudeDriver over stream-json, permissions and questions on the phone
The second driver behind the same trait: claude -p with stream-json both
ways, the hidden --permission-prompt-tool stdio flag (without which no
permission ever reaches a client), text deltas streamed from raw API
events, tool_use/tool_result mapped to tool events, and can_use_tool
control requests surfaced as Question events -- plain permissions as
Allow/Deny, AskUserQuestion as one Question per sub-question with the
chosen labels sent back in updatedInput.answers keyed by question text
(wire shapes pinned by live probes against CLI 2.1.237, recorded in the
module doc). The CLI session id is persisted per session dir, so a
backend restart respawns with --resume and loses nothing. set_model
rides the control protocol and persists through the manager; the spawn
screen grows model/cwd/permission-mode fields.

Also: the dev CA now carries proper keyUsage/basicConstraints
extensions (strict verifiers reject it otherwise) -- regenerated and
re-pinned before any real phone has installed the app.

Verified: 20 unit tests + clippy clean; scripted end-to-end over the
HTTP API (AskUserQuestion round trip, Bash permission allow, streaming,
restart with --resume remembering earlier work, delete); and on the
emulator, a live haiku session asking Tea-or-coffee and acknowledging
the tapped answer.

irisandClaude Fable 5 967fc814ab Phase 1 server: TLS + token auth, session registry, EchoDriver, SSE with cursors
The whole pipe behind one Driver trait and a common event model:
spawn/list/delete sessions, message + question answering, append-only
JSONL transcripts whose sequence numbers are the phone's resume cursor
(surviving backend restarts), bearer-token middleware wrapping every
route including the fallback, wg0-only binding that fails closed, and
first-run token enrollment via a terminal QR.

Verified: cargo test (10), clippy clean, and curl end-to-end over pinned
TLS -- auth rejection, spawn, streamed SSE replay/resume, /question
round trip, restart continuing seq numbers, delete removing everything.
