Mohamed BoudraandElsa Granger ac775a2904 Reveal collapsed navigation as a touch overlay on wide layouts (#8739)
* feat(app): swipe open collapsed tablet navigation

Reuse the retained sidebar and mobile panel motion for a partial-width
navigation overlay when the wide dock is hidden. Preserve the dock
preference, project gestures through the sidebar width, and dismiss the
overlay when revealing workspace content.

Reset the animated frame width explicitly across dock transitions and
keep the resize origin on the UI thread.

Validated on Duo portrait and landscape, iPad portrait and landscape,
iPhone full-width navigation, and browser sidebar interactions.
Typecheck, lint, targeted formatting, and 31 relevant tests passed.

* fix(app): refine touch navigation overlays

Enable navigation swipes only on touch-capable runtimes and reject mouse
and pen input per gesture event. Allow swiping from anywhere in the
workspace instead of requiring an edge start.

Cover the full application window with the backdrop, including safe-area
padding, and remove the wide overlay's inline close button. Preserve
swipe, backdrop, and destination-selection dismissal.

Validated interior swipes on Duo and iPad, mouse exclusion in a browser,
and full-window dimming and dismissal in Duo portrait and landscape.
Typecheck, lint, and targeted formatting passed.

* refactor(app): let the panel store drop the overlay target on dock

Docking the sidebar, or any layout that no longer presents it as an
overlay, now drops the transient agent-list target inside the panel
store. App chrome publishes one left sidebar presentation (overlay,
dock, hidden) instead of an effect in SidebarChrome watching flags.

* refactor(app): answer fine pointer and touch screen from one module

Merge use-fine-pointer and use-has-touch-screen into
hooks/pointer-capabilities, which reads both answers from the media
queries it subscribes to. The touch answer now comes from
(any-pointer: coarse) instead of navigator.maxTouchPoints, which that
query's change events never reported.

* fix(app): keep the phone web drawer on its edge swipe

Restore the 32px left-edge start for the compact web navigation drawer,
so interior rightward swipes over terminals, code blocks, and diffs stay
with their horizontal scrollers. The wide navigation overlay still opens
from anywhere. The edge rule moves into resolveMobilePanelGestureIntent
so both drawers share it and it has a test.

* refactor(app): one sidebar handler per destination

Settings, host settings, add host, add project, and every navigation
row now use one handler that closes the navigation overlay before it
navigates. Closing is idempotent, so the docked sidebar shares it and
the overlay ? mobile : desktop handler pairs go away.

* refactor(app): resolve the left panel width in one place

MobilePanelsProvider now resolves the left sidebar width (full window
on compact, the saved width clamped to the safe viewport on wide) and
exposes it through the panel runtime. The open and close gestures, the
overlay frame, and the docked sidebar all read that value, so gesture
travel and panel width cannot disagree. MobileGestureWrapper no longer
recomputes it, and the panelWidth/width parameters go away.

* docs: fold the wide navigation overlay into the mobile panel rules

Move the facts the overlay PR appended into the sections that own them:
the destinations intro, store ownership of the agent-list target, the
projection widths, gesture pointer and edge rules, and the sidebar
presentation bullets.

* fix(app): keep the sidebar pans live across dock and overlay switches

On an Android tablet, opening the dock with the header toggle and collapsing
it again left the touch swipe unable to open the overlay until the app
reloaded. Swipe-to-close from the sidebar also stopped working after the
same toggle cycle.

Both pans took the dock/overlay state through RNGH's `.enabled()`. On
Android, RNGH 2.32 cancels the native handler when `isEnabled` changes and
resets its config on every update. After a false -> true flip the handler
stayed inert. `.enabled()` now carries only the device capability (touch
screen present), which does not change at runtime. The dock/overlay state
moves to a UI-thread derived value that fails the gesture in
onTouchesDown, next to the existing non-touch pointer check.

The wide sidebar's workspace list now always receives the close gesture
ref, as the compact sidebar already does. Toggling it between undefined
and the ref rewired the list's simultaneous handlers on every dock switch,
and that also left the close pan dead after a toggle cycle.

This is a native RNGH handler behavior, so there is no unit repro. It was
verified on the Android fold emulator: toggle open, toggle closed, swipe
opens the overlay, swipe on an empty sidebar strip closes it, no reload.

* fix(app): keep the workspace full width after collapsing the dock

On an Android tablet, opening the dock with the header toggle and
collapsing it again could leave the workspace at the docked width, with a
blank strip on the right, until the overlay was next opened. Elsa's
original head showed the same.

The sidebar's panel host flips between an in-flow dock and an absolute
overlay. Its width came from a Reanimated style that read the React
`overlay` flag, so the width reached the native view on the UI thread
after React had already committed the new presentation. Layout logs on
the fold emulator show the lag on every toggle-open: the workspace laid
out at width 0 while the docked host still had the overlay's full window
width, then a second pass laid out the 320dp dock. When the late update
was lost on collapse, the workspace kept its dock width.

The host no longer has a width of its own:
- The dock sizes to the inner sidebar view, which already carries the
  animated resize width.
- The overlay host is absoluteFill, which covers the whole row including
  the safe-area padding.

With no animated layout prop on the host, a presentation switch is one
React commit, and the host and the workspace lay out in the same pass.

Device evidence on the fold emulator:
- Toggle open and collapse cycles: the host and the workspace lay out
  together (320/521dp, then 841/841dp).
- A swipe opens the 320dp overlay with a full-window backdrop, and a
  swipe on the sidebar closes it.
- Dragging the dock edge still resizes the dock and the workspace
  together.

There is no unit repro: the defect is the ordering of Reanimated's
UI-thread layout updates against React commits.

* fix(app): cancel pending sidebar swipes when docking

An opening swipe still has the agent target until release. Leaving overlay presentation must advance its revision even then, so motion ownership and queued commits reject the obsolete swipe.

* fix(app): keep mouse selection free of the touch-only pan's capture

On a touch-capable browser the navigation pan registers pointer listeners
over the whole workspace. Gesture Handler's web pointer manager captured
the pressed element before the handler saw the pointer, and captured it
again on every move, so a mouse drag that the pan rejects stayed captured
and the browser's selection stopped at the starting paragraph.

The patched manager now captures after pointer-down, and only a pointer the
handler still tracks. The resize handle and touch swipes keep capturing.

* fix(app): drop the compact Explorer target when the layout widens

Opening the Explorer on a compact layout selects the `file-explorer` mobile panel target. Widening
the window (unfolding a foldable, rotating a tablet) kept that target, because the store only
heard the left sidebar presentation, which is `overlay` on both compact layouts and wide layouts
with a collapsed dock. The navigation swipe begins only from `agent`, so on the wide layout every
swipe was rejected until something else reset the target.

App chrome now publishes the whole panel layout (compact or wide, plus the left sidebar
presentation) and the store drops any target that layout does not present.

* fix(app): keep wide overlay sidebar content inside the left safe area

The overlay starts at the window's left edge, over the workspace's
safe-area padding, so its content now takes the left inset itself. The
dock already sits inside app chrome's padding and stays unchanged.

* fix(app): return an interrupted swipe to its anchor when docking cancels it

Docking mid-swipe bumps the panel revision while keeping the agent
target. The command treated the unchanged target as motion already in
progress and skipped the animation, leaving the dragged position
stranded between anchors. A command that interrupts a drag now always
animates to its target.

Co-authored-by: Elsa Granger <zeyugao@outlook.com>

* fix(app): synchronize startup panel selection and gate pending swipes

A child layout effect can publish panel layout before the motion provider subscribes. Establish the current selection when subscribing, then observe later commands. Recheck presentation eligibility before gesture activation so docking also cancels touches that have not started dragging.

* test(app): cover panel subscription through its public contract

Verify initial snapshot delivery, later commands, and unsubscription directly in the existing panel-store suite instead of mounting test-only React components.

* test(app): reopen compact navigation after leaving settings

Destination navigation clears the transient overlay selection. Reopen the compact drawer before asserting its configured footer rather than relying on a stale open target surviving a wide layout.

* test(app): open navigation by keyboard in composer focus checks

Navigation pans intentionally reject mouse drags. Use the keyboard sidebar command to exercise focus and fullscreen Escape behavior without relying on the former mouse swipe helper.

* fix(app): complete sidebar integration after main rebase

Retain the resize width resolver and format the shared division-width and hybrid touch-sizing integration.

* test(desktop): give split browser panes room for tab rails

After #8740, narrow panes replace tab rails with compact dropdowns. The desktop browser journey counts and selects rail tabs, so widen the real Electron content window before splitting instead of treating missing narrow-pane rails as missing panes.

* test(markdown): require growth while holding a streaming paragraph

* test(markdown): isolate image arrival from reload positioning

Mounted row totals change as history virtualizes, so observe the new response and tool directly. Hold the real PNG response after reload until the reading position settles, then verify its reserved height and viewport instead of attributing initial bottom-follow positioning to image decoding.

* fix(android): keep inverted chat still during text selection

React Native decomposes Android list inversion into a 180-degree rotation with positive scaleY, so the existing visibility-scroll guard never recognized the inverted viewport. Inspect the composed matrix and reproduce the actual list transform through the native view manager in regression tests.

* fix(markdown): linked inline code keeps inline code size

* fix(markdown): reserve a placeholder box with an image glyph while images load

Slash-separated English pairs were recognized as file links in prose. Require stronger path intent there while preserving the existing inline-code recognition rule.

* fix(markdown): horizontal blocks own their drags on compact layouts

* perf(markdown): keep native streaming updates in the unfinished tail

Native markdown reparses each updated view in full. Keep parser-closed blocks in a memoized head during paced reveal, then reunite completed prose for cross-paragraph selection. Preserve trailing spacing and source indentation at the split.

* perf(markdown): reuse Android measurements across view mounts

* test(markdown): bare Fabel/model and daemon/client stay plain text when copied

a502cfd0d stopped linking bare two-segment prose paths; the clipboard
expectation still carried the links from the earlier loose pattern and
failed on CI (playwright shard 1/4 on 60b4e2d05). main expects the plain
text, so restore that.

* perf(app): limit native chat mount batches

Whole-message Markdown rows measure synchronously during Fabric layout. Render fewer history rows per batch and retain a smaller offscreen window so opening a chat does not measure twelve history rows at once.

* fix(app): keep populated markdown in sync with native layout

Fabric can collapse streaming blocks before asynchronous rendering replaces the old text, producing a blank frame. Commit populated-view updates synchronously while retaining worker preparation for first mounts to avoid moving large history parsing onto the UI thread.

* perf(app): preserve unchanged sidebar workspace projections

Reopening a retained sidebar rebuilt its entry collection and invalidated every project row despite unchanged workspace data. Preserve collection identity as well as row identity, while keeping membership and ordering changes observable.

* Revert "perf(app): preserve unchanged sidebar workspace projections"

paseo-bot[bot] 0255738ee7 Copy only the highlighted text when a selection starts below an image (#6195)
* fix(app): leave out an image when a copied selection starts below it

A drag that starts in the gap below an image in an assistant reply
anchored at the start of the image's rendered internals, ahead of the
hidden img, so the copy included the image's Markdown although only the
text after it was highlighted. A selection that starts inside an image
and ends past it now starts after the image.

Closes #6187

* fix(app): keep a failed image when a copy starts in its error text

A failed image shows its error message as text inside the image frame. A
selection that starts in that text selected part of the image, so it keeps
the image's Markdown. Only a selection that starts inside the frame before
any of its text starts after the image.

paseo-bot[bot] 950e1f8f41 Keep an image's alt text and source when copying a selection from an assistant reply (#6181)
* fix(app): copy an assistant image as its Markdown, with alt text

Selecting across an image in an assistant reply copied the rendered img,
which has no alt text and, for data and workspace images, points at a
preview URL. The image frame now carries its Markdown source and alt text
the same way other Markdown elements declare their copy form.

Closes #6163

* fix(app): copy an image selected on its own as its Markdown

A selection inside the rendered image left the image's copy attributes
on the frame outside the range, so nothing was copied as Markdown.

* test(app): name the image-only selection in the copy spec

paseo-bot[bot] 18412604dd fix(app): copy only the code when a selection touches the block beside it (#6138)
* fix(app): copy a code block without its fence when the drag starts beside it

A drag that starts or ends in the gap beside a code block anchors the
selection at the edge of the neighbouring block. Only the code is
highlighted, but the range crossed the block boundary, so the copy took
the Markdown path and wrapped the code in its fence.

A selection now crosses a code block only when it selects content
outside it. Message rows the range touches without selecting anything
are dropped, and a selection whose content all lies inside one code
block copies as that code.

* fix(app): keep a selected image when copying it beside a code block

An image selected next to a code block has no text, so the selection
counted it as empty and copied only the code. Count images as selected
content so the copy keeps the image and the fence, as it did before.

Mohamed Boudra 135a3b4c9e Find text in assistant messages that streamed in the open chat (#5146)
* fix(app): find text in assistant messages that streamed in the open chat

Chat find failed with the generic "check the host connection" text
whenever the oldest hit sat in a response that streamed while the chat
was open and had more than one Markdown block. Presentation rendered
such a message as one row per block with ids `<messageId>:block:n`,
while hydrated history stayed one row with the raw message id, and every
message-addressed DOM lookup (find reveal, scroll-to-message, history
reveal, the render-cap expansion) only knew the raw id. The reveal step
polled for a row that never existed and gave up after five seconds.

The defect was the dual rendering, so this removes it: every assistant
message is a block group however it arrived, single-paragraph messages
included, so a row id is never a message id. Rows carry
`data-message-id`, `getStreamItemMessageId` is the one way from a row to
its message, and find, scroll-to-message, history reveal and selection
copy address messages through it. Chat find force-mounts every row of
the selected message under virtualization so counts span the whole
message, and pins the chosen occurrence to its row while the scroll
settles. Link reference definitions fold into their neighbouring block
so history never paints an empty row. Find failures now say what went
wrong (connection, history changed, could not show the match) instead
of blaming the connection for everything.

* fix(app): let the Markdown parser decide which blocks are link definitions

A hand-rolled CommonMark regex rejected destinations markdown-it accepts,
such as escaped spaces, so those definitions still became their own empty
row and the neighbouring paragraph lost its link. The block splitter now
parses the block with the same parser: no tokens plus registered
references means definitions only. The two new chat find journeys move
their mechanics into named helpers so the test bodies read as intent.

Mohamed Boudra 3bca9b7a92 fix(app): preserve selected list markers when copying (#3055)

Mohamed Boudra 84b735fbea fix(app): preserve nested list clipboard lines

e99eb7de3d fix(app): keep line breaks and indentation in copied code (#2935)
* fix(app): keep line breaks and indentation in copied code

#2930 strips the pre/code tags from a partly selected code block, which
is right for the Markdown syntax but leaves the code itself going
through Turndown as prose. Turndown collapses whitespace, so two
selected lines arrive as one, the indentation is gone, and
Markdown-significant characters come back escaped.

Divert a partial code selection before that: copy the selected text
verbatim. Fully selected regions are untouched and still produce a
fence, which is what hasSelectedAllContents was already deciding.

The html half needs pre for anything multi-line -- HTML collapses
newlines too, so a rich paste target would lose the lines the same way.
A single line stays undecorated, matching the rule that a partial
selection does not carry its container's formatting.

Two trailing-newline fixes ride along, since both make a paste run code
nobody asked to run. Newlines between rendered lines are their own text
nodes, so a selection that overshoots the end of a line carries one;
strip it. The block's Copy button was handed the raw fence body, which
ends in a newline; hand it the rendered text instead.

* fix(app): strip every trailing blank line from copied code

The Copy button stripped one trailing newline, so a fence whose author
left a blank line before the closing delimiter still put an executable
newline on the clipboard. Pasting that into a terminal runs the last
line, which is the thing the strip existed to prevent.

Both copy paths now share one regex in markup.ts and remove every
trailing break, plus any indentation that followed the last one.

Mohamed Boudra 098122be8d Keep copied assistant selections within their visible boundaries (#2930)
* fix(app): respect assistant copy selection boundaries

Selection serialization reintroduced semantic ancestors even when the user selected only their inner text, causing list markers and code delimiters to expand beyond the visible range. Preserve semantics only for complete selected nodes, and keep rich list payloads compatible with text composers that prefer HTML.

Mohamed Boudra adf33930b3 Preserve assistant selection formatting when copying (#2808)
* fix(app): preserve formatting when copying assistant selections

Browser selection serialized React Native Web layout nodes instead of the assistant message semantics. Recover semantic markup from renderer-owned metadata and reuse the rich clipboard generator used by Copy turn.

* fix(app): preserve assistant copy semantics

Carry source-only Markdown metadata through the selection copy boundary, unwrap generated code links, and cover ordered starts, hard breaks, and fence languages in Playwright. Refresh the Nix dependency hash for the added clipboard dependency.

* fix(app): preserve partial selection context

Wrap selected fragments with their shared semantic ancestor chain and enable GFM table and strikethrough conversion. Cover partial nested selections and GFM output through the browser clipboard.

* fix(app): preserve copied list and autolink text

Adjust partial ordered-list starts for omitted siblings, strip parser-generated anchors before Markdown reconstruction, and refresh the Nix dependency hash computed by CI.

* fix(app): normalize partial selection context

Normalize cloned ordered lists across block boundaries, degrade incomplete table fragments to selected text, and preserve table alignment provenance through Markdown reconstruction.

* fix(app): escape copied table delimiters

Rendered table cells no longer retain source escape characters. Escape literal pipes during DOM-to-Markdown conversion so copied tables preserve their column structure.

* fix(app): preserve authored link semantics

The rendered link boundary conflated parser-generated links with authored autolinks and discarded authored titles. Carry title semantics into the anchor and unwrap only links with explicit generated provenance.

* fix(app): preserve nested copy structure

Blank-line splitting separated loose nested lists before Markdown rendering, leaving no nesting for clipboard serialization to preserve. Derive protected separators from the Markdown block structure and keep copy metadata independent from monospace surface styling.

* fix(app): preserve selected file links

Assistant messages and rich clipboard HTML must apply the same link validation policy. A shared parser keeps file links semantic in both MIME representations while retaining markdown-it's unsafe-scheme rejection.

* fix(app): preserve partial table content

A selected body row wider than its retained header cannot be represented as GFM and is truncated when rich HTML is regenerated. Treat only those over-wide fragments, plus headerless fragments, as incomplete while preserving valid short rows.
