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

The phone has been running the debug build: build-apk.sh assembled it, and
nothing in the app or its report said which build a frame time came from.
A debuggable build runs Compose at a fraction of release speed, so the
tuning so far was measured against the wrong number. On the emulator, the
same fixture and gestures: measure 1.4ms mean / 14.7ms worst on debug,
0.8ms / 6.6ms on release.
build-apk.sh now assembles the release variant, signed with a key it
generates once under ~/.config/ai-app (beside the pinned CA, outside any
checkout). The report's header names the build. The one native library is
declared kept-with-symbols so packaging stops warning about an NDK the
build does not need.
Also: ui-sandbox.sh keep now keeps the config too. The server appends
spawned sessions and enrolled tokens to it, so regenerating it left the
transcripts on disk and the registry empty.

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 transcript's remaining lag was the newest assistant reply: transcriptUnits
kept the last row whole -- right while it streams (splitting a changing text
is a parse per delta), wrong forever after, so a session that ends on a long
reply drew it as one lazy-list item with every node alive. On a Pixel 9 Pro
XL that was 13.8ms of draw phase a frame, 79% of it the framework's own
per-node bookkeeping, against a 34,996px item.
An AssistantMsg now carries `settled`, folded from the status event that ends
its turn (status changes are transcript events with seqs, so replay settles
the same way), and cleared if a delta ever grows the message again. A settled
newest reply splits like every other. Folding it -- rather than reading the
screen's status -- routes the resplit through the held-events gate, so it can
only happen at the newest end while pinned, never under a reader. The
"session is working" predicate now lives once, in sessionWorking().
Measured on the emulator, same session and gestures, a 43KB reply as the
last row: draw phase 3.92ms -> 1.20ms per frame, framework share 3.07ms
(78%) -> 0.54ms (45%), worst single measure 82.5ms -> 9.1ms. The report's
"on screen" line went from one 60,674px AssistantMsg to five blocks of
95-846px. A live streamed turn settles and splits the moment it goes idle.
The harness half, asked for by Bryan: ui-sandbox.sh now derives its port and
root from the checkout name (two checkouts' sandboxes cannot reach each
other), keeps its token in ~/.config/ai-app/sandbox-token and salvages
enrolled device tokens across restarts (enrol the emulator once, ever), and
gained the driving verbs every UI session was re-inventing in /tmp: spawn,
send (text or @file), api. transcript-bench.sh is the standard
scroll-and-report measurement. AGENTS.md documents all of it.

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.
