Mohamed Boudra 4f7813d3aa Keep the tapped line in place when chat disclosures expand or collapse, with the native timeline on LegendList (#8717)
* Keep a disclosure's trigger in place on web

Expanding or collapsing a turn summary, tool-call group, tool call details
or todo badge now holds the row that owns the trigger. Rows inside the
timeline get a disclosure context; each toggle runs its state change through
`useDisclosureHold()`, and the viewport's new `holdRow(rowId, apply)` replaces
`holdReadingPosition()`.

On web the hold pins the reading anchor to that row, stops following output,
and resumes following when the change leaves the list at its end. Native keeps
its previous behaviour (detach, then apply) until the anchored toggle lands.

* Render the native chat timeline with LegendList in forward order

The native timeline was an inverted FlatList. Disclosure toggles moved their
trigger, and a cold open settled visibly. It is now a forward-order LegendList
that stays virtualized, and one owner moves the scroll offset at a time:

- Before placement: LegendList's initial scroll, behind its hidden reveal.
- While following: the end pin (native-end-pin.tsx). This is a zero-height first
  child at the bottom of the content, which native maintainVisibleContentPosition
  keeps in place. A content shrink or growth never scrolls from JS; only a
  viewport resize or an explicit jump does.
- During a disclosure hold and while detached: LegendList MVCP with
  shouldRestorePosition (native-disclosure-hold.ts), so a toggle keeps its
  trigger at the same y and paints one layout change.
- Every newly mounted row starts at a per-kind estimate (new-row-estimates.ts).

PaseoScrollView defers React Native's content clamp while MVCP is set. A shrink
below an unmoved anchor no longer draws a frame past the end (RN #58578,
PR #58695). VisibleContentPositionClampTest covers this.

LegendList 3.7.1 patch, one "Paseo patch" comment per hunk:
- The content height comes from React state on the new architecture.
- Rows get a per-row size estimate.
- The MVCP anchor lock runs on native too. Upstream gated it to web in d24a9d93
  without a native reason. Without the lock, the size pass for prepended history
  re-anchors on a prepended row and moves the rows on screen. Native ends the
  lock when its row leaves the view, not on the 300 ms clock.
- Header and footer reveal together with the rows.
- Only lists that keep their end preserve the initial end.
- A remeasure within one pixel plus the 1/8 dp floor of the known size is
  noise. Upstream compares the raw size with the floored one, so the live
  turn's assistant row (1380 -> 1381 px) read as a resize and moved every row
  a frame after the reveal.
- The Android silent initial scroll retry sends its 1 dp nudge and the return
  to the target in one task. Upstream returns on the next frame, but its 16 ms
  check can finish the scroll first and cancel that frame, so the list revealed
  3 px short of its end and moved into place a frame later.
- The top-padding shrink hold applies on iOS only.

Android, emulator. Evidence is in .artifacts/legend-impl.
- J1, J2 at the end, J3, J4, J5, J6, J7: pass.
- J2 while streaming: not reachable on the Ten second stream fixture; its turns
  never fold.
- J8: no blank frames over 10 fresh flings, at host load 32-37.

J4: still. Before these two hunks, 6 of 7 cold opens moved every row one frame
after the reveal. After them, 9 valid cold opens show no shift. 5 of those
were traced through the nudge path. Runs that hit the dev client's startup
SIGSEGV in MountingCoordinator::pullTransaction were left out. That crash is
in the emulator's dropbox from before this work.

* Revise a history row when its turn summary line changes

LegendList renders a row again only when its item changes. The forward-order
timeline in d1f2ae352 folds a finished turn into its host user message, but the
host's item does not change when the fold appears, so a turn that folded live
lost its summary line until something else revised the row.

collapseTurns now reports the hosts whose summary line appeared, changed or went
away since the previous fold (updatedHostIds), and the history row revision
treats them as changed content.

* Stop following the end while a user scroll owns the viewport

The bottom anchor controller kept sticky-bottom for the whole of a drag and its momentum and only
decided at the end. While it is sticky the native list mounts the end pin, so a drag started during
a stream had every new line move the rows under the finger: on the iOS simulator the offset jumped
by each line's height (+22, +35, +22 pt) mid-drag, and Android does the same with the same code.

beginUserScroll now detaches. endUserScroll resumes following when the gesture ends at the end
(scrolling there without animation) and otherwise stays detached and drops any pending anchor, as
before. The re-stick is not animated: on Android a line that mounts during a smooth scroll cancels
it, and the list then followed 40 pt short of the end until the controller detached it.

Measured after the change, frame by frame:
- iOS and Android, drag up mid-stream: the content tracks the finger and momentum with no line
  steps; the stream grows below; tapping the pill re-sticks and follows again.
- A short drag at the end, mid-stream: following resumes; the release lands on the end in one
  frame (the drag distance, here 8 pt on iOS and 21 dp on Android).

A line already mounting when the drag begins can still move the rows once in its first frame,
because the detach reaches native one commit after the touch.

* Correct the iOS scroll view under maintainVisibleContentPosition

Phase 2 of the LegendList timeline. The native timeline relies on maintainVisibleContentPosition
for the end pin and the disclosure hold, and React Native 0.86 on iOS gets two cases wrong.
modules/paseo-scroll now registers PaseoScrollViewComponentView, a subclass of
RCTScrollViewComponentView, for the iOS scroll view, like PaseoScrollView on Android.

- A mount that removes its own anchor: detaching removes the end pin in the same mount that opens
  the tapped disclosure, and the offset jumped by the removed view's frame. The subclass keeps the
  offset when the anchor's tag is no longer registered, the check React Native 0.88 adds in
  https://github.com/react/react-native/pull/57294. That PR's extra superview check is not copied
  because it skips anchors detached by removeClippedSubviews
  (https://github.com/react/react-native/issues/58910).
- A shrink at the end: UIKit clamps the offset to the new end during the mount, then React Native
  adds the anchor's movement, so a turn folding while following landed above the end
  (https://github.com/react/react-native/issues/58578). The subclass restores the pre-mount offset
  for the adjustment and clamps after it, as
  https://github.com/react/react-native/pull/58695 does.

The dev client was rebuilt with the module. Verified on the iPhone 16 Pro simulator, frame by frame:
the summary far up and the latest turn's summary while following each keep the trigger at 0 px
with one layout change per toggle, the todo card the same, the cold open lands still, older
history pages keep the visible rows in place, and the keyboard, send-time shrink and streaming
stay pinned to the end.

Freshly mounted markdown on iOS paints one frame after its layout, because enriched-markdown
renders asynchronously (https://github.com/software-mansion/enriched-markdown/issues/1131). A
synchronous first render removed that frame but raised fling frame time at p90 and p99, so it is
not part of this change.

docs/agent-stream-disclosure.md now describes the clamp correction on both platforms.

* Keep the rows under the finger at a drag's start and its release

Two one-frame row movements remained around a user scroll while the timeline streams.

A drag's first frames. The end pin stays mounted until JS stops following, one round trip after
the drag begins, so a line mounting in those frames scrolled the rows under the finger by its
height. Both scroll view subclasses now skip the content-position correction while the user drags
and the anchor is the end pin, which they recognise by its native ID ("paseo-end-pin"). Android
overrides scrollToPreservingMomentum, the position keeper's only scroll call, from the begin-drag
event until the finger lifts; iOS skips the adjustment while the scroll view is dragging. The skip
is limited to the pin: LegendList's own anchoring for the detached list also uses the native
correction, and a history page landing mid-drag needs it. It starts at the drag rather than at
touch-down: a tap or long press while following would otherwise leave the list stranded short of
its end, still following, once the finger lifts.

The release. A gesture ending within 32 pt of the end re-stuck with an instant scroll, a snap of up
to 56 px. Following now resumes only when the finger lifts at or past the end, or momentum stops
there, within 1 px, the distance web resumes at (strategy-web.tsx). Anything else stays detached with the
pill. The check runs when the gesture is decided, so output that arrived below meanwhile counts. A
release past the end counts as at the end: on iOS it bounces back, and a line landing during the
bounce scrolls in as following would. endUserScroll takes isAtEnd, like releaseDisclosure.

Tests: VisibleContentPositionClampTest gains growth at the end during a drag (red before the
change: the offset moved by the 120 px growth, 352 -> 472) and growth without a touch (the pin
still follows); the module suite passes on emulator-5558, 11 tests.
bottom-anchor-controller.test.ts: a release near but short of the end stays detached.

Device, frame scans while streaming (dev clients rebuilt):
- Android, 8 slow drags with a pill tap between: no frame moves against the finger once a drag
  starts; the stream follows between drags. Three short releases 50 px short of the end stay put
  until the pill; three drags back past the end resume following.
- iOS simulator, 6 drags: no line step during any drag or its momentum. Two short releases stay
  detached with no snap; three drags past the end resume following within 0.5 s of the bounce.

* Document the LegendList timeline and remove what the inverted list left

The native section of docs/agent-stream-disclosure.md described the FlatList hold (anchor
neighbour, native child index, frame spacing, render window). It now covers why the timeline is
forward order, who owns the offset in each state, the hold and its sync layout trigger, user
scroll and release, draw distance numbers, the LegendList patch and the scroll view corrections.

Draw distance stays at 2000. The spike measured it on a chat with a 15,000 px turn expanded: 500
blanked the viewport 1.0 to 1.5 s per fling and 2000 not at all. A re-measure on the collapsed chat
(500, 1000, 1500, 2000, interleaved) blanked at no value and its jank followed host load, which
stayed between 19 and 40, so it could not separate 1000 or 1500 from 2000.

The patch file now opens with a header listing its eight hunks by purpose and linking
LegendApp/legend-list#593, which reports each one upstream. The markdown doc records the iOS
first-paint delay (software-mansion/enriched-markdown#1131).

Removed with the inverted list: PaseoScrollView's child-reveal override (a no-op without the
inverting transform) and ScrollSelectionTest, the invertedWrapper style, and the inverted-list
passages in android.md, native-text-selection.md, mobile-testing.md, floating-panels.md and
agent-stream-performance.md. model.test, layout.test and footer-spacing.test still asserted the
inverted native order and failed; they now assert forward order, and footer-spacing uses the
real strategies instead of an inverted stub.

* fix(app): show a reply's footer when the next prompt arrives on native

LegendList re-renders a mounted row only when its item or extraData changes.
When a new prompt arrives, the previous reply's footer moves from the live
auxiliary slot into that reply's layout item (completedFooter). The reply's
StreamItem keeps its identity, and renderItem is a stable event, so the row never
rendered its new layout and the footer (copy, timing, fork) disappeared until the
row remounted. FlatList had the same gap.

The history renderer is now LegendList's extraData. Its identity changes with the
history layout map, and StreamRow's memo limits the pass to rows whose layout
item changed.

* test(app): run the web disclosure hold cases in a real browser

The three hold cases simulated layout in jsdom: hand-written row heights,
scroll clamping and resize callbacks. They could pass while Chromium paints
the trigger somewhere else. They now run in Vitest browser mode with real
layout, ResizeObserver and scroll clamping. The two hold cases fail when the
hold is bypassed.

The browser project pre-bundles @tanstack/react-virtual, so its first import no
longer reloads the test mid-run. The lucide stub gains ArrowDown, which
pane-find imports.

* fix(app): let a drag end a disclosure hold on native

A drag detached the bottom controller but kept the disclosure hold. Every item
size change restarts the hold's quiet frames, including a streaming row's, so
the hold can outlive the toggle. While it lasts, shouldRestorePosition accepts
only the held row. Once the drag scrolls that row away, a history page arriving
mid-gesture gets no anchor, and the rows the reader was on move by the page's
height.

The drag now cancels the hold without releasing it. The controller keeps no hold
state of its own beyond detached, and the gesture's end decides whether following
resumes.

* perf(app): keep the scroll-to-bottom button's state out of the timeline

Opening a tool call or turn at the end of the chat now holds its trigger in
place, so the timeline detaches and the scroll-to-bottom button appears. That
visibility was useState in AgentStreamView, so showing the button re-rendered
the whole timeline view for a change only the button reads. The viewport now
writes near-bottom into a per-agent store that only the button subscribes to.

* fix(app): show the scroll-to-bottom button on native whenever following has stopped

A gesture now resumes following only when it ends within 1 px of the end, but
the button still hid within 32 px. A release 2-32 px short of the end left the
list detached with no button to return. While detached the button now hides
only at the end; while following it keeps the 32 px tolerance so content
growth that the offset trails for a frame does not flash it. The button also
updates when following starts or stops without a scroll.

* fix(app): stop the timeline jumping when the keyboard opens or closes on native

The keyboard's settled height was committed to the list after the motion, as
paddingTop on Android and contentInset.top on iOS, to keep the top of the
history reachable under the translated dock. While following, the end pin
absorbed it in the same mount. While detached or holding a disclosure, nothing
did: Android's native anchor is LegendList's ScrollAdjust view, which padding
does not move, and LegendList compensates a padding change only on iOS. Every
row jumped by the keyboard height 0.2-1 s after the keyboard settled, and back
after it closed. On send, the same commit raced the jump to the end.

The keyboard now only translates the list with the composer. The cost: while
the keyboard is open, the composer viewport clips the top keyboard-height of
the list, so the start of a short conversation is hidden until it closes.

* chore(app): describe the native timeline as LegendList in stream comments

* fix(app): keep a disclosure's trigger in place when its row is cut off at the top on native

LegendList's idsInView starts at the first fully visible row. When a turn host's prompt bubble
sat above the viewport, a disclosure hold found no anchor in the data pass (shouldRestorePosition
rejects every other row), and the size pass anchored on the row below the host instead, so the
trigger moved by the host's size change. The patch appends the partly visible rows to idsInView
after the fully visible ones, so the held row anchors while every pass that does not restrict the
anchor keeps the first fully visible row.

The browser test renders the patched native build, which vitest now aliases instead of the
package's unpatched web build.

* fix(app): let a turn's summary line collapse again after it opens

The React Compiler cached StreamRow's `renderStreamItem(layoutItem)` on the layout item and the
renderer. The revised item that useRevisedHistoryRows hands a row whose display state changed only
fed the row id, so the row reused its cached content. Opening a turn usually inserts its rows
directly below the host, which also gives the host a new layout item. When another row sits
between them, such as a compaction marker, the host kept its layout item, its summary line stayed
collapsed, and every later tap asked to open the turn again.

The renderer now takes the item it renders, so the compiler's cache keys on the revision. StreamRow
moves to its own module, which the tests compile the way Expo does.

* test(app): alias the patched LegendList build in browser tests only

Unit tests load @legendapp/list outside Vite, so the native build's react-native import skipped
the react-native-web alias and reached React Native's Flow source, failing every unit suite that
imports the native strategy.

* fix(app): keep a size-only disclosure's trigger in place when its row is cut off at the top on native

LegendList's prepareMVCP picks the anchor for a size change with no data change as the first row
in view, without asking shouldRestorePosition. A disclosure that only grows its own row (a todo
card) while that row's top was above the viewport therefore held the row below it, and the trigger
moved by the row's size change. The patch now applies shouldRestorePosition to size changes as it
already does to data changes.

* test(app): render the timeline row revision test in a real browser

The repo's unit tests do not mount components in JSDOM. The test still compiles stream-row.tsx with
the React Compiler, so it fails when a revised row ignores the item it was handed.

8d424e039e Reduce rendering cost in long chats (#7052)
* perf(app): stop re-walking the timeline on every streamed delta

Every coalesced delta rebuilds the stream render model with the same
tail. The model re-sliced the tail at the history-window start on every
call, so the rendered tail was a fresh array per delta and every WeakMap
keyed on it (ordering, history split, turn timing, the layout history
cache, row revision) missed each time. Cache the slice by tail identity
and window start.

Turn timing then still walked the whole rendered tail per delta and
allocated a new assistant-timing Map, which the layout memo depends on.
Split the walk: the tail is walked once per tail identity and the head is
walked from the carried open turn per delta. The Map keeps its identity
while the head adds no completed turn.

Adds identity-contract tests and a vitest bench for the per-delta
pipeline. 200 deltas over a 2,000-item timeline, mean per run:
default mounted window 5.68ms -> 2.82ms, history fully revealed
16.95ms -> 1.81ms.

Fixes #4816

* perf(app): keep the stream view's per-delta work bounded by the head

The chat outline concatenated tail and head, reduced over the result in
the render body, and rebuilt jumpToPrompt on every delta even when the
outline was disabled, which is every native viewport. Memoize the tail's
contribution, scan only the head per delta, do nothing while disabled,
make jumpToPrompt a stable event so the rail's memo holds, and republish
the active prompt only when the index or reading position changes.

The view built a Set of every mounted id plus the live head per delta for
the outline's pending-jump check; key it on mounted history only and
treat live head rows as always mounted. Split plugin projection so a head
change does not re-project the tail, memoize the history-window boundary
lookup, and read the turn presentation's submission flag with some()
instead of allocating a filtered array.

Mohamed Boudra 2a0a0ff656 Keep mobile workspace switching responsive with long chats (#3610)
* perf(app): bound native workspace mount work

Native workspace switches retained inactive React trees and mounted large chat histories in aggressive list batches, making Hermes and Fabric work scale with prior usage.

Retain only the active native workspace, reveal a shared turn-aligned history window locally before daemon pagination, preserve desktop retention semantics, and pace native list mounting.

* test(app): cover bounded history journeys

Exercise local history reveal and hidden outline jumps through the production browser viewport while preserving held-page pagination and scroll anchoring.

* fix(app): reveal fetched outline targets

A bounded merged jump could load its target before the mounted history window, leaving the pending jump unable to scroll. Reveal fetched hidden targets through the existing history-window capability, then scroll once they mount.

* test(app): follow anchored history reveals

History-start helpers could stop at a transient edge before local window expansion restored the content anchor. Retry the real wheel or keyboard action after geometry settles until the timeline remains at history start.

Mohamed Boudra 8021d2b6c9 Keep agent timelines stable from submission through resume (#2718)
* Reapply: Stop completed turns from appearing stuck (#2484)

* Reapply: Keep older chat history and image previews stable (#2490)

* Lock timeline layout stability with user-driven specs

Two reds reproduce the reported jank:
- new agent, first prompt: the row paints at top=100 then jumps to 144 through
  authoritative hydration, because the draft tab and the agent panel each render
  their own AgentStreamView for the same logical row.
- long loaded timeline, submit: scrollHeight collapses 10793 -> 9111 mid-turn,
  because splitOrderedTail reclassifies measured rows into the virtualized segment
  where the virtualizer falls back to estimateStreamItemHeight.

Also restores centered timeline rows: the pagination anchor wrapper introduced in
#2490 was a plain block div, which broke alignSelf: center.

* Measure the turn footer blink from when the footer appears

Bounding the window at the prompt row conflated two things: the footer arriving a
frame after the row, and the footer leaving the layout and coming back. Bounded from
the footer's first frame, the blink still reproduces, so the footer-ownership race is
real rather than a sampling artifact.

* Rename the shadowed prompt row binding in the frame recorder

* fix(desktop): allow concurrent worktree dev instances

Desktop terminals can inherit another instance's profile path and debugging flags. Scope the profile to the current dev root and select an available debugging port so instances do not share global runtime state.

* fix(desktop): expose development providers in dev builds

Desktop-managed daemons inherited no Paseo runtime mode, so dev builds constructed the production provider registry. Mark unpackaged internal launches as development while continuing to force packaged launches to production.

* fix(timeline): stabilize optimistic turn layout

Keep initial history loading dormant until user intent and preserve active-turn layout across delayed transport updates. Add painted-frame coverage for optimistic timeline transitions.

* fix(timeline): preserve optimistic prompts through hydration

Canonical replacement relied on a transport submission record that can settle before a provider echoes the user row. Keep presentation continuity owned by the unreconciled row while destructive history replacement remains governed by active transactions.

* fix(timeline): make submitted prompts canonical

Submission settlement previously depended on status updates that could arrive after the optimistic row. Persist every accepted prompt in the canonical timeline and keep the footer active until RPC and canonical acknowledgement converge.

* fix(timeline): stop older history pages repeating entries

Backward pagination counted source sequence rows, so page boundaries inside a merged projected item could return that item repeatedly. Count projected entries and advance from their display anchors instead, with server and browser regressions covering the contract.

* fix(timeline): resume agents from the latest history

Use a bounded tail probe on resume so long background runs appear atomically instead of replaying every missed page. Preserve unchanged views, reconcile local/live rows, and keep skipped history reachable through backward pagination.

* fix(timeline): reconcile turn state after missed updates

Turn completion events can be missed while an agent timeline is unsubscribed, leaving footer activity stale even after the directory reports idle. Reconcile the single-owned turn lifecycle from authoritative resume snapshots while preserving newer live evidence.

* test(timeline): cover running state across refresh

Protect the hydration boundary where directory state must restore consistent tab, composer, and footer activity. Expose the running indicator semantically so the regression checks user-visible state instead of spinner implementation details.

* fix(timeline): keep history loading geometry stable

Reserve a fixed history-start gutter regardless of pagination state so showing or hiding the loader cannot shift timeline content.

* fix(timeline): keep turn activity coherent

Derive footer, tab, and composer activity from one lifecycle and submission projection. Idle directory transitions now request an authoritative resume so missed terminal events converge without treating directory delivery order as turn authority.

* fix(tests): align checks with runtime boundaries

* fix(desktop): stop dev app surviving its terminal

Electron was detached from the desktop runner, allowing it to outlive a stopped workspace terminal with broken output pipes and retain the single-instance lock. Keep Electron owned by the runner and preserve explicit process-group cleanup for detached child trees.

* fix(timeline): preserve activity through turn handoff

Correlate lifecycle events and snapshots with daemon-owned turn identity, and keep optimistic submissions active until their canonical row arrives. This prevents stale updates and RPC timing from exposing a false idle state.

* refactor(timeline): remove submission timing state

* fix(timeline): restore prompt identity on resume

* fix(timeline): exclude attachments from canonical prompt text

Structured provider prompts can include hidden history attachments before the user's text. Persist only plain prompt blocks so authoritative user messages match what the composer displayed while provider input remains unchanged.

* refactor(agent): remove unused pending-run message identity

* fix(desktop): let Chromium allocate the debugging port

* refactor(agent): remove impossible finalized-turn tracking

* fix(timeline): load history after keyboard scrolling

Treat observed upward displacement as user intent so keyboard and scrollbar navigation can wake dormant pagination.

* test(server): preserve accepted turn stream order

The manager-owned accepted turn boundary intentionally precedes coalesced output. Assert that lifecycle event explicitly while retaining the timeline-before-terminal ordering contract.

* test(app): scope sidebar fixtures by identity

Shared E2E daemon state may contain unrelated projects. Keep stale-route coverage tied to its named missing project and drag only the two rows seeded by the reorder spec.

* fix(timeline): gate prompt revisions by client capability

* fix(timeline): finalize canonical prompt delivery

Treat provider identity as a single stored-row transition so legacy clients receive one deliverable canonical prompt. Release identity-pending rows before later foreground output or the current terminal while preserving stale-turn isolation.

* fix(server): preserve legacy prompt pagination

* fix(timeline): keep assistant block identity stable

Assign canonical block IDs during live promotion so terminal finalization cannot remount image-bearing rows.

* fix(timeline): apply covered revisions during resume append

Run the exact canonical revision pass before overlapping resume pages append newer rows, while leaving cursor advancement to the incremental path.

* fix(server): preserve queued agent transitions

Project each queued live snapshot before awaiting stored metadata so later lifecycle state cannot overwrite an earlier transition.

* fix(server): snapshot queued agent updates

Capture each live agent payload before it enters the per-agent queue so shared nested state cannot change while an earlier storage read is pending.

* docs(app): date agent turn compatibility cleanup

* refactor(timeline): mint submitted prompt identity at acceptance

Canonical prompt rows now keep one immutable wire identity while provider identity remains internal for rewind translation. This removes the unreleased same-sequence revision and legacy projection contract.

* refactor(app): remove prompt revision reconciliation

Submitted prompt rows are immutable on the wire, so resume and live reducers no longer need to apply already-covered same-sequence updates.

* test(app): cover submitted prompt rewind roundtrip

* docs(timeline): describe immutable submitted prompt identity

Provider echoes now enrich daemon-internal identity only; wire rows keep their acceptance-time identity and rewind performs the provider translation.

* test(server): validate mock rewind targets

Reject unknown provider message IDs so app rewind coverage exercises wire-to-provider identity translation.

* fix(server): validate rewind before interrupting

* fix(server): omit rewind identity for daemon prompts

* test(app): guard rewind eligibility and rejection

* fix(server): preserve prompt identity across hydration

* refactor(timeline): remove stale revision remnants

* Revert "fix(server): preserve prompt identity across hydration"

This reverts commit 6adcf7e5b0.

* fix(timeline): settle missed submission acknowledgements
