Auto already allows most of what a session does, so the prompts it did
raise were mostly the interruption without the choice -- and on a phone
each one is a round trip to a question card. Measured rather than
assumed: a haiku session spawned this way ran a bare `echo` and a
`sleep` loop with no prompt at all.
The stricter modes stay one tap away in the same picker, which is where
a session that warrants one picks it.

**The scroll.** The transcript scrolled on new items and nothing else,
which missed the two cases that matter most. An imported session's history
arrived and left the view wherever it landed; the keyboard opening shrank
the viewport and slid the newest messages under the IME, so typing meant
typing into a view showing the middle of something.
The view is now pinned to the tail, and it is the reader's scroll that
decides: settling anywhere above the bottom releases the pin, settling
back at the bottom re-arms it. The pin is written only when a scroll
*ends*, so it survives the moment when new content has just pushed the
bottom away but the reader never moved -- deriving it continuously from
"is the bottom visible" would release it on every append, which is the
race that makes naive follow-the-tail implementations let go at random.
New items and viewport resizes both re-scroll; the jump is instant rather
than animated, because an imported session appends hundreds of items at
once and animating through them is a light show.
**The input field gets a row of its own**, above the buttons. Sharing one
row put the full width behind three controls, so the thing being typed
into was the narrowest thing on the row.
**Permissions default to auto, and importing can choose.** The spawn
screen defaulted to "manual" and imports passed no mode at all, so the
CLI asked about everything -- and 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. Both paths now default to auto, with the other modes
one tap away for a session that warrants caution.
Looked at running, all three: an imported session opens at its bottom,
the tail stays visible while typing with the keyboard open, and the mode
picker shows auto selected.
The four Kotlin files that were the link rather than this product now come
from the submodule: the pinned TrustManager, the enrollment store and its
Keystore sealing, the QR capture activity, and the local-network permission
check. `:link` is a subproject resolved by path, so the app half is
version-locked to the same commit the Rust half already was.
What stays here is the two facts that are actually about this app, and
both are load-bearing in a way that would fail quietly if got wrong: the
`aiapp` URI scheme, and the Keystore alias `aiapp-token-key` that every
enrolled phone's token is already sealed under. A wrong alias would leave
those phones reading as not enrolled with nothing on screen to explain it,
so the value is carried over exactly and the reason is written beside it.
Call sites are unchanged. `ServerSettings` stays available unqualified as
a typealias and `applyPinnedTls()` stays an extension, so the diff is the
three files that bind the product-specific values plus two imports --
rather than every screen that happens to use a setting.
Also clears a warning the build had been printing: `setup?.id.orEmpty()`
where the compiler already knows `setup` is non-null, because `chosen`
came from that setup's own provider list.
Verified by running the build, not only by reading it: ktfmt, Kotlin
compile and Android Lint are all clean with no warnings, and the APK still
builds -- which exercises the pinned-CA generator, since that is the step
that reads the CA off this machine.
Still unpushed, per the hold until the rebuild bug is proven fixed. Note
the submodule: a checkout of this commit needs `git submodule update
--init` before `app/` or `server/` will build.
The driver worked and the models could be downloaded, but the spawn screen
had no idea llama.cpp existed: the model field and every extra setting were
gated behind `isClaude`, so a llama provider offered nothing, `model`
arrived null, and the driver refused with "a llama.cpp session needs a
model". The feature was reachable only by curl, which is not what was asked
for.
A llama provider now gets the models this backend has downloaded, as a
picker rather than free text -- there is nothing sensible to type, and a
name that is not on disk is a session that cannot start. Context size and
temperature are there too, blank meaning llama.cpp's own default rather
than a zero. Spawn stays disabled until a model is chosen, because without
one the button could only fail.
**Two bugs that only appeared by pressing the button**, both mine, both
from changing the server without re-driving the app:
- The app sent the setup's *label* where the server had started resolving
by *id*. The failure was almost self-diagnosing -- `no setup named "this
machine" -- configured: this machine` -- and that message now says "no
setup with id" and lists ids, since listing labels was what made it read
as a contradiction.
- The session header showed `on local`, the id, because the app read
`setup` where the server had begun sending both `setup` (id) and
`setupName` (label). The app now carries only the label: nothing in it
addresses a setup, and holding both is what let it show the wrong one.
Verified by doing it: rediscovered the local machine from the phone so
`local-llama` appeared, spawned a session on Qwen3-0.6B-Q8_0 with a 4096
context, sent "Reply with exactly one word: ready", and it replied "ready"
with 125 tokens counted.

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.

The server half went to rustfmt's defaults earlier today; this is the same
move for the app, and the same reasoning. Kotlin ships no formatter with
the Gradle build, so the question was which to adopt: ktfmt is Kotlin-org
owned now (it moved from facebook/ktfmt), is a formatter rather than a
configurable linter, and has essentially nothing to tune -- which is what
rule 27 is asking for. ktlint's .editorconfig surface is the thing that
rule warns against, and detekt is static analysis, whose job Android Lint
already does here.
One setting, and it is a choice between the tool's own two styles rather
than a tuning: kotlinLangStyle() is the 4-space one, which is what this
code already was. The 2-space default would have reindented every file to
say nothing.
./gradlew :androidApp:ktfmtFormat to apply
./gradlew :androidApp:ktfmtCheck to verify
Formatting only. The one thing worth checking by hand was the generated
PEM constant, since a leading newline there costs Android's
CertificateFactory its preamble sniff and fails at runtime nowhere near
the cause: ktfmt moved `.trimMargin()` onto its own line and left the
template alone, and the regenerated constant still starts at the opening
quotes.
Verified after: ktfmtCheck, compileDebugKotlin and lintDebug all pass, and
the APK builds.

SpawnScreen kept its own `loading` flag and `error` string, the third
mechanism in this app for a state two screens already share. That was not
just untidy: on a failed fetch it set the error, left `providers` and
`hosts` at the empty lists they started as, and rendered the form anyway --
so "couldn't reach the server" arrived as a Provider row with no providers
in it, which is what a server offering nothing would also look like. The
error sat below both empty pickers.
It now holds `LoadState<SpawnOptions>` like the others: loading shows the
spinner, a failure reports and stops, and the form exists only where there
is something to fill it with.
The spawn action keeps its own error, renamed `spawnError` so the two can't
be confused again. They are different in kind and the distinction is the
one the session list just learned: a fetch that never answered leaves no
form worth showing, while a spawn the server refused leaves a filled-in
form the user still wants, so that one stays beside the button that
produced it.
Verified on the emulator: the form loading with both providers, the Claude
fields appearing when claude-cli is selected (which also exercises the
snake_case kind the phone now compares against), and the failure state with
the server stopped -- reporting alone, with Cancel still working.

`kind: r#claude-cli` was the config file paying for a serde default. RON is
modelled on Rust, a hyphen is not an identifier in either, and this file is
edited by hand -- so the escape existed only to write a name nobody would
have typed that way. Snake case, and it reads `kind: claude_cli`.
The same string is the one the phone compares against to decide whether to
offer models, a working directory and permission modes, so SpawnScreen.kt
moves with it. That is a wire-format change: Dev Updater delivers the
server before the APK, so between the two an installed build sees a kind it
does not recognise and drops the Claude-specific fields from the spawn
form until the APK lands. It recovers on its own, and nothing else reads
the value.
The provider *name* is left as "claude-cli". It is a label a person picks
and may edit, and sessions reference providers by it -- renaming the
default would orphan them.

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.

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.

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.

Compose app mirroring local-updater's stack (single :androidApp module,
pinned CA, HttpURLConnection transport) plus what this app needs on top:
a bearer token sealed with an Android Keystore AES-GCM key, an
aiapp://enroll intent filter so scanning the server's terminal QR with
the stock camera enrolls the phone with no QR library, an SSE client
that resumes by transcript cursor, and a transcript renderer folding the
common event model into user bubbles, streaming text, collapsible tool
cards, and answerable question cards.
Verified on the tdep emulator against the real server: enrollment deep
link, list, spawn, streamed echo turn, question answer round trip, tool
card expansion, adjustResize keyboard behavior. Build is warning-clean
(compose.* accessors replaced with direct dependencies).
