perf(app): preserve unchanged sidebar workspace projections (#7157 )

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.

Reverting to trailing-only adds a full window to the first character of every turn. Same shape and the same reason as `TerminalOutputCoalescer`.
 - **The leading flush adds a canonical row, and that is fine.** A burst's first chunk lands as its own timeline row. `mergeAssistantChunks` / `mergeReasoningChunks` in `timeline-projection.ts` join contiguous same-turn rows, and clients read the projected timeline, so history is unaffected. Tests that assert on raw rows have to account for the extra row; tests that assert on what a client sees do not.
 - **The store holds the full text; only the rendered slice is paced.** Copy, selection, the chat outline, and scroll geometry all read the same string the user can see. Pacing the store instead would leave the bottom anchor chasing a content height that is ahead of the reveal.
- **Markdown blocks belong to presentation, and every assistant message is a block group.**
-  `agent-stream/presentation.ts` splits a message into one display row per Markdown block, the same
-  way whether it arrived streaming or as fetched history. Splitting in the reducer instead would
-  discard paragraph separators and expose fragments to plugin callbacks, which need the whole source
-  text. Live-head work stays cheap by parsing only the growing last block during append, retaining
-  completed blocks by object identity, and caching the split per source item so a tail change does
-  not re-split history. History was once left whole to keep cross-block Markdown context; that gave
-  one message two shapes depending on how it arrived, and message-addressed features only worked on
-  one of them.
- **A row id is never a message id.** Block rows are `${messageId}:block:${n}` with
-  `blockGroupId = messageId`, including single-block messages, so nothing can come to rely on the two
-  being equal. `getStreamItemMessageId` in `presentation.ts` is the only way to go from a row to its
-  message, and web rows carry it as `data-message-id` alongside `data-history-row-id`. Anything
-  addressing a message — chat find, scroll-to-message, history reveal, the find expansion that lifts
-  the render cap — uses the message id and must expect several rows to answer to it. Row ids stay for
-  React keys, virtualizer measurement, scroll anchors, and per-row caches like assistant image
-  occurrence keys.
+- **One source assistant message is one display row.** Presentation projects plugin output and caches unchanged history. The shared [Markdown renderer](markdown-renderer.md) owns rendering on every platform. Chat paces the visible source and applies a 32,000-character render cap on web; native keeps the complete message. The native renderer keeps closed blocks in a stable head and sends the paced suffix to a separate tail view during streaming; completion reunites them for selection. This stays inside the renderer, without promoting blocks into timeline history.
+- **Message identity survives completion.** Assistant row ids are source message ids. Plugin rows can replace a source, so find, scroll-to-message and history reveal still use `getStreamItemMessageId`. Width-specific measurements describe whole rendered messages.
 - **First sight of a text is revealed whole.** Only growth is paced. This is what makes history hydration, timeline replay, a virtualized row remounting on scroll, and an already-finished message all render complete on first paint without a special case for each.
 - **Leaving `phase: "streaming"` snaps the reveal.** A completed turn must never be left holding characters. `layoutStream` sets the phase, so anything outside the live head with an active turn is already complete.
 - **The reducer queue commits on a frame, with a timer as the ceiling.** A frame callback never fires in a hidden tab, so a timer races it and wins when nothing is painting — the store has to keep advancing either way.

+
+## Native parsing cost
+
+The native library reparses and measures its entire `markdown` prop on each update. During streaming, the renderer splits source at an mdast block boundary and memoizes the head, so per-frame updates parse only the tail. Boundary discovery runs when a source line completes, rather than on every reveal frame. The unfinished line and final parsed block stay in the tail, preserving list continuation, setext headings, tables and open fences. Reference-dependent source and HTML retain a larger tail because later source can change their meaning. A single long block therefore still carries its full parsing cost.
+
+Completion restores one native text view per Mermaid-delimited segment, so selection crosses prose paragraphs again. The head retains its trailing block margin while split. JS reveal remains the pacing source; native opacity animation stays disabled.

 ## Measuring

 - **Smoothness (user-perceived):** `packages/app/e2e/browser/agent-stream-smoothness.spec.ts`, gated behind `PASEO_AGENT_STREAM_PERF_E2E=1`. Drives the mock provider's `bursty-stream` model and reports coefficient of variation of characters painted per frame (smoothness) plus p95 gap between visible updates (stalls). Both numbers are needed: a stalled stream is perfectly smooth.
 - **Reproducing bursty arrival:** the `bursty-stream` model in `mock-load-test-agent.ts` emits uneven runs of tokens separated by idle gaps. Burst sizes come from a seeded generator, so a run repeats exactly.
 - **Rate policy in isolation:** `computeRevealStep` in `packages/app/src/agent-stream/text-reveal.ts` is pure; `text-reveal.test.ts` covers convergence and burst flattening without a renderer.
+- **Per-delta cost on a long timeline:** `npx vitest bench --project unit src/agent-stream/stream-tick.bench.ts` from `packages/app` replays 200 deltas over a 2,000-item timeline through the pure model and layout pipeline, with the default mounted window and with history fully revealed. It measures the JS work per delta, not paint.

+sheet and tab, so callers open targets the same way on every layout. Each such sheet holds one

+other sheet in the app, so it sits on the one app-wide stack: a sheet opened from any sheet, a
+subagent chosen from the subagents list included, lands on top of it, and closing the top sheet
+(drag, Close, backdrop, or Android Back) uncovers the one below. The list stays open under the
+sheet it opened; see [menus.md](menus.md#selecting-an-item-on-ios) for the row contract.

+mounts tabs in different trees, so every screen below remounts. The draft owner
+restores the text and the editing session restores the caret. Focus restoration
+is limited to mouse-driven UIs, using the same fine-pointer policy as autofocus.
+New workspace keys its sessions by draft in the app-level store for the same

+composer: a retained tab keeps its fullscreen editor mounted while hidden, the
+sheet suspends pane focus, and the composer gives up input from the moment the
+user asks for the compact agent list or explorer, before the panel's motion
+settles. Pane focus itself stays put under those panels: the agent panel reads
+it as "the user is in this chat" for attention clearing, and opening the agent
+list must not clear the attention it shows. On mouse-driven UIs, focus restoration

+Native and touch-web navigation must not replay old editor focus, including

+Fullscreen toggles keep the editor mounted and need no focus restoration.

+height as a bottom margin at move start and end (boundary-time, like the

+# Markdown rendering
+
+Use `MarkdownRenderer` for chat replies, file previews, plans, pull requests and changelog content. It uses `react-native-enriched-markdown` on iOS, Android and web. Keep source adaptation and renderer configuration in `components/markdown`; consumers supply Markdown and, when needed, its file location.
+
+Native selection belongs to the library's text view. Keep an assistant message in one row so selection can cross paragraphs, headings and lists. Code blocks and tables use the library's native views and their selection behavior. Web uses browser selection over semantic HTML. Once its WASM parser is initialized, the library parses synchronously for the first commit of each mounted row; an empty interim row would corrupt virtualized measurements and move the reader. Chat owns paced reveal, the web render cap, message identity and list measurement. Native renders completed messages together. While streaming, it keeps closed blocks in one head view and updates a separate tail, then reunites the text on completion. See [native parsing cost](agent-stream-performance.md#native-parsing-cost) for the boundary and pacing constraints.
+
+## Links and images
+
+Workspace file links use the shared file-link resolver. The workspace supplies its client, root and open-file action once; chat can supply the agent's more specific context. URLs use the same link press path. Recognized inline-code paths stay tappable. The library callback carries the tapped occurrence’s syntax context. Preserve it when opening files: explicit Markdown links decode URL escapes, while recognized inline-code paths preserve literal percent characters and use suffix lookup. Identical URL strings in different occurrences must stay distinct. Explicit absolute workspace links receive a relative hover title; existing authored titles remain intact.
+
+Resolve workspace image paths over the existing session RPC, then give the library a cached native file URL or web blob URL. HTTP(S) images pass through unchanged. This preserves relay, SSH and local socket connections, which do not expose a daemon HTTP endpoint. Each mounted renderer owns its image acquisition identity, so a later reply reads a rewritten path again while the earlier mounted reply retains its snapshot. Image taps open the attachment lightbox. File previews resolve relative images against the Markdown file's directory.
+
+## Engine constraints
+
+The pinned nightly has the same React Native package and core source trees as upstream commit `73ac5085eb1fdc743973b3473d4dba65abad5261`. Compatibility was checked with React Native 0.81.5. Native dependencies must be rebuilt when changing the highlighting configuration; JavaScript refresh cannot enable compiled grammars.
+
+Math and video are disabled. Task lists and admonitions are enabled; task checkboxes are read-only. Source adaptation spaces adjacent empty GFM table delimiters before escaping prose spoiler delimiters and decodes entity text before the engine can discard it. Code spans and fences keep their literal source. Comment HTML is normalized to Markdown before parsing; details show their summary and body expanded.
+
+Mermaid fences use the existing isolated diagram runtime and fullscreen viewer. Web dispatches them through the library’s code-block override. Native has no block-renderer hook, so the renderer extracts only Mermaid fences and places the existing WebView host between library-rendered segments. This is the only block exception; see [native selection limitations](native-text-selection.md) for diagram grouping and leading inline images. Streaming keeps the last valid diagram visible while the next revision renders.
+
+Native code blocks use the library's copy control and compiled grammars. Web code blocks use `HighlightedCodeBlock` through the library's `renderers.codeBlock` override. The patch also preserves web list numbering and link titles, marks pending parses with `aria-busy` so Find waits for rendered text, and carries link syntax through native and web tap events. Web inline code inside a link inherits only the link colour; its code font, size and background stay intact. Keep link variants colour-only: native pills replace text runs and prevent paths from wrapping; Android pills also use the surrounding block’s font size. The package patch is tracked by [upstream PR #997](https://github.com/software-mansion/enriched-markdown/pull/997); remove the patch when the pinned release includes it.
+
+The package patch also keeps overflowing native horizontal blocks in control of their drags: Android claims parent interception at touch-down and releases it for vertical drags so the chat list can scroll; iOS keeps its scroll recognizer active for outward drags at the leading edge. This prevents compact sidebar pans from taking block scrolling without changing sidebar swipes on prose or non-overflowing blocks. Native changes require a client rebuild.
+
+Android measurements use a size-only, 512-entry LRU across view unmounts, matching the library’s existing iOS cache. Scrolling back through history can reuse layout sizes without parsing those rows again. Content, layout props and width identify each entry; font-scale changes and native layout invalidation discard affected sizes. The cache retains no views or spans.
+
+The library determines how incomplete Markdown appears during streaming. Completed text uses the same component and engine as history. Find and scroll-to-message address source message ids; selection-copy understands semantic HTML and the web code component's copy metadata.

+# Native compact workspace scripts flow
+
+`native-compact-workspace-scripts.android.ad` covers live script status in the compact ⋯ → Scripts sheet when nothing else keeps the host directory live. Start on a phone with a workspace open, the sidebar closed, and no agent tab selected. A viewed agent tab or the open sidebar hides the failure, because either one keeps the directory subscribed.
+
+The workspace's `paseo.json` needs a long-running plain script, stopped before the run. `SCRIPT` defaults to `worker`:
+
+```json
+{ "scripts": { "worker": { "command": "node -e \"setInterval(() => {}, 1000)\"" } } }
+```
+
+The flow starts the script, checks that Stop flips its page to Run, runs it again, and checks that Restart brings it back to running with no other interaction. It ends with the script stopped and the sheet dismissed, so it can be replayed.

+`native-question-option-preview.android.ad` checks that every line of a long option preview is reachable on Android. Before replay, open a mock agent prompted with `emit synthetic questions` so its question card shows the first question, on a phone-sized emulator (validated on a 1080×1920 API 35 AVD). The flow opens the `rollout` question, drags slowly up from inside the "Behind feature flag" preview, and asserts the preview's last line is visible.
