Keep reference scope and live/history projection consistent, and retain link text when dispatching workspace file actions. * fix(app): preserve native prose entities and links while bounding preparation cost * fix(app): preserve provisional syntax at cached reveal boundaries * fix(app): bound prose append work and preserve markdown edge cases * fix(app): preserve home paths and normalized prose links * fix(app): preserve parser-owned links and streaming tilde tails * fix(app): keep growing markdown on the streaming block renderer * fix(app): preserve bracketed IPv6 links in native prose * fix(app): skip prose classification for blocks over the render cap * fix(app): share selectable native prose across Markdown surfaces * fix(app): preserve Markdown containers before grouping prose * revert(app): remove shared prose-run renderer changes Reverts ab4737bb2 and ac47e1063 before replacing the Markdown engine across all platforms. * feat(markdown): use enriched renderer across all platforms * test: verify library image controls and isolate website config * fix(markdown): preserve file links and image revisions * fix(markdown): restore diagrams and preserve link origin * fix(markdown): retain diagram identity and reference scope * fix(markdown): avoid empty web history measurements * fix(markdown): preserve authored empty link titles * test(markdown): exercise find across whole-message history * fix(markdown): preserve encoded image paths after rebase Keep the shared renderer image normalization and file-read regression coverage that originally lived in the main integration merge. * fix(markdown): derive table and task list colours from the theme * fix(markdown): restore selection highlight on web * fix(markdown): restore file link hover tooltips on web * fix(markdown): normalize inline HTML before rendering * fix(markdown): create renderer types when applying package patch The published nightly omits both MarkdownRenderers type files. Represent them as new files so patch-package succeeds on a fresh npm install, matching the already patched development package. * fix(markdown): keep the renderer tree stable while images resolve * fix(markdown): size inline images to the line and collapse failed loads * fix(markdown): normalize only parsed HTML nodes * fix(markdown): keep the first image reference definition * fix(markdown): preserve complete assistant messages on native * fix(markdown): classify web links explicitly and complete renderer types * fix(markdown): preserve spacing between HTML elements * fix(markdown): normalize HTML following code elements * fix(markdown): preserve literal image fallback labels * fix(markdown): retry transient image decode failures * docs(markdown): record native selection and image limitations * fix(markdown): preserve first definitions across Mermaid segments * fix(markdown): reserve pending images and harden web rendering * test(markdown): cover state retention during image arrival * fix(markdown): preserve reader position while responses grow Keep the same message component boundary when a live row becomes retained history, preserving Mermaid runtimes and selection nodes. Observe paced child text commits at the web viewport so sticky-bottom follows before the next frame. * 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(markdown): preserve adjacency around inline HTML * fix(markdown): keep summary block boundaries outside bold text * perf(markdown): scan HTML block boundaries incrementally * test(markdown): gate delivery while establishing a held reader * test(markdown): name shared renderer setup and file actions * test(markdown): assert linear HTML boundary work without timing * test(markdown): check large HTML table output without observing built-ins * fix(markdown): restore accentBright link colour * fix(markdown): require letters and known extensions in bare path recognition * fix(markdown): match main's blockquote, bullet and h6 colours * 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 * fix(markdown): bare prose paths need an extension, line suffix or depth 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" This reverts commit a3919faed4.	2026-10-16 21:03:37 +07:00
3 people	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 Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * 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	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.	2026-09-21 22:31:08 +02:00
Mohamed Boudra	5d70ab2ab8	fix(app): restore character-paced streaming replies (#5013) ... * fix(app): restore character-paced streaming reveal Restore the v0.8 character reveal model and remove the word-level fade implementation so streamed assistant and reasoning text remains opaque, grapheme-safe, and immediately completes when a turn ends. * fix(android): preserve inverted timeline selection React Native's prebuilt Android library does not consume source patches under node_modules. Register the compiled scroll manager before the core package so inverted child-reveal calculations leave focus and text selection in place while normal and explicit scrolling remain unchanged.	2026-09-17 18:32:12 +02:00
Mohamed Boudra	6215e08efe	Smooth streaming replies with a continuous left-to-right fade (#4859) ... * feat(app): reveal streaming text as one continuous fade front Streaming assistant text is released by word and every character fades in over the same 150 ms envelope from a start time owned by the message. Start times never decrease in reading order, so a line paints as a single front moving left to right, however the text is chunked. Per-word envelopes with an internal stagger let the next word's first letter overtake the previous word's last letter, which read as holes and flashing words at the real frame rate; 100 ms frame strips hid it. Native renderers receive the fade ranges as a prop on a host view wrapping the root Text, so ranges and text land in the same Fabric mount transaction. The earlier binding sent ranges through a separate async module call keyed by view tag and had to reconcile them against the view's text; on a fast phone the UI thread lags JS by several commits, mounts and calls interleave, and every reconciliation heuristic guessed wrong. Native code no longer infers newness or creates start times. The mock load-test provider now separates cycles with a blank line so a cycle heading is not appended to the previous paragraph. * fix(ci): refresh streaming dependencies and isolate E2E setup * test(app): distinguish fade cleanup from Markdown replacement * test(app): detect restarted fades during Markdown updates * docs(app): keep streaming guidance focused on constraints and QA * test(app): control animation time in Android fade assertions Fixed wall-clock sleeps let emulator scheduling select the sampled animation frame. Inject the animator time source and drive paint at exact timestamps within one UI-thread operation; production keeps the system clock. Verify the mid-fade sample and the exact cleanup boundary without sleeps, polling, or retries. * fix(test): compile the desktop renderer before lifecycle checks The lifecycle fixture treated Metro /status as app readiness. Its first Settings click therefore spent its 90-second UI budget compiling the cold bundle. An isolated cold-cache run restricted to one CPU reproduced the click timeout before the app runtime had loaded. Reuse the browser suite's existing bundle warmup before launching Electron, and preserve Metro output in the lifecycle artifacts. The UI timeout, build-request timeout, lifecycle assertions and product behavior are unchanged. CI did not preserve Metro output, so its precise startup timing is not recoverable from the failed run. The retained log makes subsequent startup failures diagnosable without relying only on an empty renderer text dump. Validation: three complete lifecycle E2E runs under private Xvfb displays; existing Metro readiness tests; app typecheck; targeted lint; root format. * test(file-observer): await burst delivery through native recovery The deletion phase required every event within 10 seconds, but native coalescing recovery uses a 30-second safety audit followed by the existing reconciliation debounce. An idle diagnostic excludes that delayed audit and therefore cannot act as a completion barrier. Await the required delivered events instead, preserving every deletion assertion and the existing overall test watchdog. A real-filesystem test with controlled native notifications reproduces 95 outstanding paths at the old deadline and verifies completion when the safety audit delivers them. No production observer behavior changes. * test(file-observer): verify burst recovery through public events The controlled-clock regression constructed a private native backend, bypassing the interface used by consumers. Consolidate recovery coverage into the public observer integration test instead: drive real writes, deletes and directory renames, then await every required public event, including the 450 surviving files at their renamed paths. No public capability was added: subscribe callbacks already express completion. No production behavior or test timeout changes. * test(app): drive Android fade tests through the native host The instrumentation suite constructed TailFadeInAnimator directly, advanced its private clock, and counted FadeInSpan instances. It now mounts the WordFadeHost that React mounts, feeds it the ranges prop the bridge sends, and asserts rendered pixels: hidden before a start time, a monotone front inside and across words, settled frames equal to the baseline, and no frame callbacks left after settling. Span counts and internal timing state are no longer asserted. Choreographer cannot be advanced deterministically from a test and the fade epoch is the message's wall-clock start time, so the host takes a WordFadeFrameClock (time plus frame callbacks) as its smallest public seam; production keeps the Choreographer-backed default. Fixture text is sized in pixels so every sample stays on one line at any density; at 420 dpi the 32sp fixture wrapped and the column helper summed glyphs from the first line.	2026-09-15 03:15:24 +02:00
4 people	0aca3b605a	fix(plugins): transform whole timeline items before grouping and Markdown splitting (#4675) ... Send every original tool call and each whole accumulated assistant message through plugin transformers before display grouping or Markdown splitting. Preserve streaming callbacks, original payloads, native Markdown block identities, and chat outline reading position. Reject legacy fragment caches and retain failing-first plugin-interface and browser regressions. Fixes #4673. Fixes #4789. Consolidates #4820.

Mohamed Boudra	8dd4da6ee0	Keep mobile streaming and panel motion stable under JS stalls (#4190) ... * fix(app): activate mobile panels after motion settles Gesture previews were publishing React presentation state and activating retained content before the native motion finished. Keep transient motion on the UI thread and publish the active panel only from the accepted animation completion. * perf(app): re-render only changed history rows Every coalesced stream tick re-rendered all mounted history rows because the inverted FlatList recreates each cell with a new index and ref. Keep layout item identity for unchanged rows and memoize the row on it, and resolve tool-call groups through a stable event so the render callbacks stop churning. * perf(app): count replica row bytes once Budget accounting measured every stored row of a touched host on each persist through the Buffer polyfill. Cache the UTF-8 length per immutable row and count without materialising bytes. * fix(app): settle mobile panels on position Activity now follows the UI-thread position reaching the canonical anchor instead of an animation completion callback. A successful gesture keeps its finishing motion and the matching command adopts it; settlement and command acceptance may arrive in either order. * fix(app): keep settled panel props across JS stalls Turn off Reanimated's FORCE_REACT_RENDER_FOR_SETTLED_ANIMATIONS. Its settled-props collector drops entries older than two seconds before React receives them, so a JS stall across a settle left the overlay display and backdrop opacity reverted on the next commit while the store held the new panel. * fix(app): reconcile hidden keyboard end on iOS Only a hidden end event resets the keyboard shift. A late visible end no longer resurrects a keyboard that already dismissed. * fix(app): focus the replacement input through autoFocus after clearing Clearing swaps the native input for a fresh instance. Focusing the doomed instance asked Android for the keyboard and then tore the focused view down, which cancelled the show; a JS focus command sent alongside the remount reached a view that was not attached yet and the IME ignored it. Focus and blur requested while the replacement is pending now decide the replacement's autoFocus, which native applies once the view is attached. * fix(app): revise history rows in every viewport The history row memo boundary bails out until its item identity changes, but only the native viewport cloned rows flagged by historyRowRevision. On web and desktop a history host whose tool-call group kept updating from the live head rendered stale. Move the revision into useRevisedHistoryRows and run both viewports' history through it. Regression test renders the web strategy with a memoized row and asserts only the revised host re-renders.	2026-09-02 00:52:44 +02:00
3 people	e22ad117fd	Stream assistant text at a steady rate instead of in arrival lumps (#3612) ... * Stream assistant text at a steady rate instead of in arrival lumps Assistant text arrived in lumps and was painted that way. The daemon coalesces one message per 60ms window, and that window carries however many characters the model produced in it, which swings by an order of magnitude within a turn. Painting each delta as it landed made the size of those lumps visible. Three changes: - The agent stream coalescer is now leading + trailing. The first delta after an idle window flushes synchronously instead of waiting a full window, matching the invariant TerminalOutputCoalescer already documents. The window stays at 60ms; shrinking it would raise message rate on a loop that already contends with terminal frames and relay encryption, without making the stream smoother. - The client reducer queue commits on a frame instead of an arbitrary 48ms timer, with the timer kept as a ceiling so a hidden tab still advances. - Assistant and reasoning text are revealed at a rate derived from the backlog rather than from arrival timing. Arrival changes the target, not the rate. The store keeps the full text and only the rendered slice is paced, so copy, selection, the chat outline, and scroll geometry all stay consistent with what is on screen. The leading flush means a burst's first chunk lands as its own timeline row. The projection already merges contiguous same-turn rows and clients read the projected timeline, so history is unchanged; the server tests that assert on raw rows were updated for the extra row. Measured on Expo web against a local dev daemon. Mock bursty-stream provider, 6s samples, paint-on-arrival vs paced: frames that advanced the text 55 -> 244, chars-per-frame CV 2.66 -> 1.44, gap p50 100ms -> 17ms. Real Claude Haiku agent over 52s: 84% of frames advance the text, CV 1.29, gap p50 and p95 both 17ms (one frame at 60Hz). Adds a bursty-stream mock model with seeded burst sizes, a gated browser perf spec, and docs/agent-stream-performance.md. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Address review: safe reveal boundaries and a testable seam Two findings from the PR review. Unicode boundaries. Slicing the revealed text at an arbitrary index could strand a lone surrogate, which paints as a replacement glyph, or split an emoji ZWJ sequence so a family briefly rendered as its members. Both were visible for a frame or two mid-stream — the exact flicker the paced reveal exists to remove. The rendered cut is now pulled back off surrogate pairs, combining marks, variation selectors, skin tone modifiers, and ZWJ joins. The reveal counter stays monotonic and only the painted boundary moves, so a long cluster cannot stall the reveal. Test placement. The hook test used JSDOM, @testing-library renderHook, and monkey-patched requestAnimationFrame, all of which docs/testing.md rules out; it prescribes fixing the missing seam instead. The reveal policy is now a pure state machine in text-reveal.ts (begin/retarget/advance/ complete/visible) covered by plain unit tests with no environment, and the hook is reduced to the frame-clock binding. Rendered behavior is left to the browser spec, which no longer carries frame sampling and statistics in its body — those moved to e2e/support/helpers/stream-smoothness.ts. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * Measure total painted text, not the tail message The smoothness sampler read the length of the last assistant-message element. A real turn emits many assistant messages, so that element keeps changing identity and its length is not monotonic — handovers read as resets, and a stream that was plainly moving on screen reported almost no growth at all. Sampling the total across every assistant message fixes it. This invalidated the numbers previously recorded for the real-agent run, so the doc table is replaced with a fresh A/B taken with the corrected sampler against a Claude Haiku agent: frames that advanced the text 6% -> 87%, chars-per-frame CV 4.11 -> 1.86, gap p50 317ms -> 17ms, p95 383ms -> 17ms. The paced column also reported zero Unicode defects across a stream containing emoji, which exercises the reveal boundary clamp end to end. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * perf(agent-stream): harden paced text reveal Use standards-compliant grapheme segmentation when available and preserve full arrivals on older runtimes. Cap reveal commits at 60Hz and measure the real browser rendering path so high-refresh displays stay smooth without rendering at hardware frame rate. * Hold back trailing fragments split by arrival boundaries The reveal boundary is not the only place a grapheme gets cut. The daemon's coalescing window ends a delta wherever the window closes, so a caught-up reveal can be handed half a cluster and paint it. Measured on a mixed-script Haiku stream: five frames in ~350 ending in a single regional indicator, i.e. half a flag on screen for a frame. While the turn is streaming, a trailing fragment that cannot stand alone — a dangling high surrogate, a trailing joiner, an odd regional indicator — now waits for the rest of its cluster. Once the turn ends everything received is painted, because nothing more is coming. Complements the grapheme-boundary clamp, which handles the reveal cut; this handles the arrival cut. The same stream now measures one such frame in ~400 rather than five. The remainder is a flush boundary that coincides with the end of an assistant message, putting the two halves in different messages, which the client cannot rejoin — that one belongs in the coalescer.
