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

The routing note under "Things that have bitten" pointed at
~/.claude/TOOLCHAIN.md, which no longer exists -- its contents were folded
into the this-machine-* skills. Name the destinations that do exist, and add
the third case: a lesson that would bite any project anywhere now has a home
in the code-lessons skill rather than defaulting back to here.
The dialog held the level for as long as it was open and read it back
from the frozen row the session screen was opened with, so reopening it
showed the old level until a return to the list refetched the row. The
level is the session screen's own datum now, like the title.
App-server sends `thread/tokenUsage/updated` once per *model request*, and a
Codex turn makes as many as it made tool calls. The translator held the last
one until `turn/completed`, so a turn's cost was reported as its final
request alone -- measured against the real rollout, 28,878 tokens for a turn
that spent 51,399 -- and the gap grows with how much work the turn did. The
context figure also stood still for the whole turn, which is exactly when it
is moving most.
Reported as each arrives instead: `tokens` now adds up to what the turn
spent, and the context figure climbs during the turn (28,921 -> 33,190 ->
35,978 on a two-file read here, matching Codex's own `last_token_usage`
exactly at every step).
Restart the history observer after every successful page so a collapsed tool page cannot consume the only layout invalidation that would request the next one.\n\nVerified with a cold 365-event tool-heavy sandbox transcript: without scrolling or expanding a group, cache coverage advanced continuously to sequence 1. Android format, compile, lint, and JVM tests pass. Transcript bench: 26 rows/26 units loaded, transcript draw 0.72 ms per frame (debug emulator).
A session whose transcript will not parse is skipped with only a log line, so
from the phone it is indistinguishable from an idle unresponsive one. That is
why the outage needed a report from Bryan rather than showing itself. The
cause is fixed; the class is not, and it is the "design the unknown state
first" rule rather than a bug in one code path.
Also rustfmt on the parse path, which the fix landed unformatted.

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