feat(chat): block-level streaming reveal with a gliding follow
Token-by-token streaming mutates the trailing paragraph in place on every tick: words rewrap, the last line jitters, and the whole reply reads as flicker. Streamed text now commits only up to the last complete line — prose arrives a paragraph at a time (a markdown paragraph is one logical line), code fences reveal line by line, tables row by row — and a shown block never changes again. A paragraph that runs long without a newline releases at the last sentence (then word) boundary so the stream never stalls. Applies to assistant text and reasoning; tool output keeps its raw tail. With growth arriving in block steps, the end follow switches to the list's animated mode so each step is a glide — reveal and scroll read as one continuous motion. The gesture opt-out now measures at-end from the live list state instead of the cached flag, which the animated glide deliberately leaves stale while trailing the edge; without that, a drag during a glide could leave the scroll-to-bottom pill unshown. Measured: end-following holds at distance 0 for the whole stream, and the mobile drag opt-out shows the pill in three of three runs. The continuous glide costs ~15% more main-thread time per streamed character than the instant follow — the price of the motion. |

fix(chat): overlay live parts on every streaming tail message
The streaming tail only overlaid the actively streaming message with live parts from the sync store. When a turn moved to its next step message, the previous message fell back to its lagging base record, briefly dropping its completed tool parts — remounting them and replaying their reveal animation once the record caught up. Overlay live parts for every message of the streaming tail via a new useSessionPartsForMessages hook, guarded so an empty live array never erases parts the record does have. Also key generate-effect glyphs by index so appended text does not replay earlier characters, and keep tool row reveal wrappers mounted unconditionally. |

fix(chat): anchored-scroll behavior parity with the reference model
Six reported defects, one root theme — our port diverged from the reference semantics: - a user gesture no longer collapses the reserved anchored end space (that snap-to-bottom was the 'anchoring vanishes on a micro-scroll'); it only disarms the follow/anchor machinery, and anchor remeasures after the user takes over can no longer re-position the viewport - the anchor arms synchronously BEFORE the send reaches the store, and the claim compares against the arm-time baseline — arming a frame after the optimistic row committed is why anchoring 'rarely worked' and sending from mid-history did nothing - gestures are selective (wheel up, touch/pointer away from the end, PageUp/Home/ArrowUp), so scrolling toward the end or clicking a row at the live edge no longer kills follow - 'at end' is a tight 40px band against the full content length instead of the list's half-viewport isNearEnd, so the scroll-to-bottom pill appears when the viewport actually leaves the end - reaching the end re-arms follow without knocking an anchored turn out of its mode, and the overlay scrollbar suppression follows scroll ownership rather than the anchor's mere existence - the status/working row moved out of the list footer to a fixed spot above the composer: inside the list it walked down with every streamed line, and its unmount was part of the end-of-stream jerk |

refactor(chat): replace timeline scroll engine with anchored-turn LegendList
Sending a message now parks that message near the top of the viewport and streams the reply into reserved end space below it, instead of jumping to the bottom and chasing it. - swap @tanstack/react-virtual for @legendapp/list in the chat timeline; the streaming tail becomes a normal list row rather than a separately rendered block, so one component owns the scroll position - add timelineScrollAnchoring: pure anchored-turn geometry plus the three scroll modes (following-end / anchoring-new-turn / free-scrolling) - replace useChatAutoFollow with useChatTimelineScroll, which opts out of automatic movement on real gestures via a generation counter instead of the timer windows the old implementation needed to recognise its own writes - move the load-older button, question/permission cards, recap, status row and bottom spacer into the list header/footer, since the list owns its container - extract useScrollShadow so the shadows can attach to that container maintainScrollAtEnd and maintainVisibleContentPosition replace the manual prepend anchor-hold and the mobile quiet-window prepend deferral. Validated: workspace type-check, lint, web build, ui tests per file. Scroll behaviour itself is unverified and needs manual testing on web, desktop and iOS. |

perf: overhaul session loading, caching, and runtime isolation (#2360)
Improve OpenChamber responsiveness under large session workloads while fixing cache, synchronization, and persistence correctness across runtimes, projects, directories, and worktrees. - prioritize selected and visible sessions during bootstrap and defer non-critical enrichment work - reduce redundant message loading, event processing, store publication, and hidden sidebar work - prevent stale session and message requests from overwriting newer authoritative state - preserve existing data when authoritative fetches fail instead of treating failures as successful empty responses - scope session materialization, messages, drafts, queues, todos, pins, permissions, folders, tabs, Git state, and pull request data by runtime and directory identity - harden runtime switching, reconnect, cleanup, mutation reconciliation, and persisted-state ordering - preserve live subagent Task linkage when metadata arrives after an older message request or while streaming parts are suspended - coalesce overlapping tail refreshes without losing newer refresh demand - improve cold-session loading by moving deferrable work out of the critical bootstrap path - isolate URL authentication, mobile credentials, native secrets, and other runtime-owned state across endpoint changes - bound long-lived caches and remove avoidable allocations from event and rendering hot paths - limit virtualization to archive collections where it improves rendering without disrupting active sidebar layout - stabilize session folders, pin ordering, expanded state, and persisted sidebar behavior - open skill files through the same secure editor and outside-workspace grant flow used by file navigation, including worktree sessions - expand regression coverage for stale completions, runtime collisions, reconnect behavior, persistence races, authoritative empty results, and subagent refresh ordering - document the updated synchronization, cache ownership, performance, and runtime-isolation invariants |

feat: merge hidden-user turns and move message metadata to turn footer
- Remove assistant message headers; show provider icon, model, agent, thinking variant, duration and time in the turn footer (metadata left, hover-revealed actions right) - Merge turns started by hidden user messages (subagent nudges) into the previous turn so Activity, footer and spacing stay continuous - Treat compaction summary text (info.summary) as justification activity in sorted mode and skip it when picking the turn summary - Interleave activity segments with standalone tool rows so Agent Task sits chronologically between activity sections |

fix(chat): anchor prompt navigator to last turn at chat bottom (#2213)
* fix(chat): anchor prompt navigator to last turn at chat bottom The scroll spy activates the last turn whose top edge crossed the reading line (100px below the container top). A final turn short enough to fit below that line could never become active — sitting at the very bottom of the chat kept the previous prompt highlighted on the navigator rail. When the container is scrolled to the bottom (within 8px), force the last turn active. * feat(chat): enable prompt navigator by default Users who already persisted an explicit preference keep their choice. |

feat(chat): prompt navigator list preview, prompt filtering, shell status fix (#2211)
* feat(chat): prompt navigator list preview with prompt filtering The hover preview is now an interactive scrolling mini-list of prompts: rows render as bordered two-line cards, the highlighted row stays inside a center dead zone and the list glides only near the window edges, wheel steps the highlight, and the panel stays open when the pointer moves into it so a click can be corrected inside the list. Rail entries are filtered to real prompts: previews are built from normalized user display parts (synthetic context stripped), fully synthetic user messages are excluded, and shell-mode messages show their extracted command via the shared shell bridge helpers. * fix(chat): render shell command status transitions The injected /shell text part carries live state in shellAction, which the render-relevant part comparator ignored — a running→completed update reached the store but never re-rendered the message row until the next send. Compare shellAction command/output/status for text parts. * fix(sync): stream shell bridge part updates while running Streaming suspension keeps part updates out of the static message records while an assistant message streams, relying on the live streaming-tail path to render it. Shell-mode bridge messages are hidden from the timeline and rendered inside the user row, so they have no live path — suspension froze their output chunks and left the card without a Show output action until the run finished. Exempt shell bridges (single bash tool part parented to a synthetic shell-marker user message) from suspension; their updates arrive at command-output pace, not delta pace. * feat(chat): syntax-highlight shell command card Render the shell-mode command and its output through the shared WorkerHighlightedCode (Shiki) with bash grammar, matching the bash tool part presentation, instead of plain pre blocks. |

fix(chat): rework prompt navigator rail into sliding tape with hover preview (#2185)
* fix(chat): rework prompt navigator rail into sliding tape with hover preview - Pin the active indicator to the target during programmatic scrolls so the scroll spy's intermediate reports don't drag it backwards mid-animation - Replace the visibility-ratio active-turn picker with a stable reading-line rule (last turn whose top is above the line), dropping IntersectionObserver - Replace the list panel with a Codex-style gutter: the whole strip is one hover/click target mapped to the nearest tick, with a per-prompt preview card that follows the cursor - Cap the rail at a fixed window of ticks; hovering the edges carousels through the rest, with gradient masks hinting at more content - Render ticks as a tape that glides to keep the active prompt centered, remounting on history prepend to avoid spurious slide animations - Keep load-earlier as a compact button aligned over the tick column * fix(chat): shrink navigator gutter when message column sits under it On narrow windows the centered message column extends under the rail's full-width invisible hover zone, which swallowed clicks on the right edge of user bubbles — including the expand/collapse control. Measure the column against the gutter and switch to a narrow hit zone when they overlap. * fix(sync): stop runaway history auto-load on sessions with empty assistant messages An assistant message fetched with zero parts (e.g. a run aborted before any output) was stored as absence — indistinguishable from parts that were never fetched. getSessionMaterializationStatus therefore reported the session as never renderable, so the ensure-renderable effects (ChatContainer, ModelControls) retried syncSession forever; each retry refetched the whole grown window and fired another background prepend, progressively loading the entire history of large sessions on open. Commit an explicit empty [] snapshot for assistant messages so fetched-empty counts as renderable, while non-assistant messages keep the absent representation and its no-op commit behavior. Reproduced and verified headless against a real 857-message session: before, 20 message fetches escalating to limit=857; after, one initial page and a single progressive-mount prepend. |

feat: add last-turn diff view
Adds a Last turn scope to DiffView that renders OpenCode snapshot diffs from the latest user message summary without re-fetching git contents. The view hides Review in that mode and carries the selected diff scope through main and context-panel navigation. Connects latest-turn changed-file chips in chat to the snapshot diff view on desktop and mobile, while keeping older turn chips static/read-only to avoid misleading affordances and extra subscriptions. Updates localized labels and empty states plus changelog. Validation: bun run type-check (packages/ui); bun run lint (packages/ui). |

perf: isolate chat streaming renders and reduce sidebar render cost (#1672)
Reworks the chat and session-sidebar render paths to cut render cascades, memory
churn, and UI jank on large sessions and big session trees. Behavior is preserved;
the changes are about *when* and *how much* the UI re-renders.
## Chat streaming
- Freeze the streaming message's parts in the bulk turn projection during streaming,
and re-inject live parts only in an isolated tail leaf, so a ~60/sec delta stream
no longer re-runs the whole-session projection or re-renders unrelated rows.
session with referential reuse of unchanged turns.
- Memoize message rows with field-aware comparators instead of reference equality.
- Replace the manual child-session polling in the task tool with the live SSE
stream + a one-shot load, removing a fetch/settle state machine.
## History loading & scroll
- Load an initial page fast, then prepend one older page in the background so the
scroll container has headroom and "load older on scroll-up" fires before the user
hits the absolute top.
- Compensate scroll synchronously (in a layout effect, before paint) for prepends —
including background prepends that don't originate from a user scroll — so the
viewport stays stable instead of judder-correcting on the next frame.
## Markdown rendering
- Render markdown synchronously *styled* on first paint (paragraphs, lists, code
cards, tables, inline code) instead of raw escaped text; the async pass then only
upgrades syntax-highlight colors. Eliminates the flash of full-width raw text.
- Load KaTeX CSS eagerly with the main bundle instead of inside the lazy markdown
chunk, avoiding a late stylesheet injection on first render.
## Sidebar
- Hoist per-row recursive tree walks out of row comparators into per-group
precomputed sets/keys; batch live-session lookups into a single map; add a
group-level memo boundary.
- Isolate rename drafts so per-keystroke typing doesn't repaint the row tree.
## Sync layer
- Add a staleness guard so a slow message fetch can't repopulate a session the user
navigated away from.
- Throw on fetch failure for authoritative loaders so a transient blip can't read as
an empty server response.
## Cleanup
- Remove dead code (unused hooks, params, duplicated inline types) surfaced while
reworking the above.
## Known issue
- A rare, purely cosmetic first-paint width flash can still appear on large sessions;
it has no behavioral or data impact and is tracked for a follow-up runtime trace.

refactor: stabilize live chat sync materialization (#1132)
Canonicalize session message/part materialization across load, prefetch, reconnect, and recovery paths so OpenChamber restores session snapshots through one consistent merge flow. Preserve live assistant streaming text when stale or delayed snapshots arrive, while still replacing optimistic user parts with confirmed server snapshots to avoid duplicated user messages. Narrow recovery triggers to explicit incomplete snapshot signals instead of broad session-event fallbacks, reducing unnecessary session refetches during active streaming. Keep turn windowing aligned with parented assistant replies and add regression coverage for materialization gaps, stale snapshot protection, optimistic user replacement, reconnect recovery, and turn grouping. |

* perf: reduce chat rerender fanout and add active-turn metrics
- Reduced sorted-mode rerender coupling by tightening turn context propagation

- Exposed new chat render counters in the debug panel for parity tracking
* fix: keep sorted activity mounted while stream grows
* fix: stabilize session and history scroll rendering
* refactor: decouple server routes from index
* refactor: extract fs module from server index
* refactor: move opencode route ownership into module
* refactor: extract notification route registration
* refactor: extract opencode and notification runtimes from index
* refactor: extract settings runtime and complete server modularization pass
* refactor: modularize server config, skills, icons, and tunnel routes
* refactor: extract server modules from monolithic index.js
Split proxy, routes, runtime helpers, and notification emitter
into dedicated modules under packages/web/server/lib/.
* refactor: replace session/message stores with SSE-driven sync layer
Delete ~9200 lines of old architecture (useEventStream, messageStore,
sessionStore, useSessionStore, questionStore, useTodoStore, client SSE).
New sync layer: event pipeline with coalescing + 16ms flush, pure event
reducer, per-directory child stores with LRU eviction, cursor pagination,
optimistic updates, deferred timeline staging, text throttle.
Migrate all UI consumers to sync hooks (useSessionMessages,
useSessionMessageRecords, useSessionStatus, useSessionPermissions, etc).
Strip session-ui-store to UI-only state, delegate SDK ops to
session-actions with abort-if-busy, optimistic store updates, and
response merging for revert/fork/archive/delete.
Add notification-store for SSE-driven session attention tracking,
cross-directory GlobalSessionStatusStore for sidebar indicators,
client-side diff snapshot sanitization to prevent memory bloat,
and revert message filtering via useVisibleSessionMessages.
* feat: notification store, session actions, activity detection
Add notification-store.ts for SSE-driven attention tracking.
Add sanitize.ts to strip diff snapshot memory bloat.
Add session-actions.ts with optimistic revert/fork/archive/delete.
Improve useSessionActivity with incomplete-message fallback.
Delete useServerSessionStatus polling hook.
* fix: add directory param to all SDK calls, fix command/shell/abort routing
All SDK calls in session-actions.ts now pass directory parameter —
required by OpenCode server to scope session operations. Without it,
abort, commands, revert, fork, and other operations returned 500.
Add routeMessage() in session-ui-store for shell mode (session.shell),
slash commands (session.command), and normal prompts. Command lookup
checks both sync child store and useCommandsStore. Handle /compact
locally via session.summarize().
Implement getContextUsage() to restore header context usage display —
reads token counts from last assistant message in sync store.
* refactor: replace custom API proxy with http-proxy-middleware
Remove ~280 lines of custom proxy code: forwardSseRequest,
forwardGenericApiRequest, collectRequestBodyBuffer, header
manipulation, hop-by-hop filtering, SSE block buffering.
Replace with single createProxyMiddleware() call that handles
SSE streaming, large bodies, and timeouts out of the box.
Dynamic router for OpenCode port changes after restarts.
Auth headers injected via proxyReq hook.
Keep: readiness gate, Windows session merge, API prefix detection.
* perf: targeted event draft cloning to fix streaming render cascade
Event handler was eagerly cloning all state slices on every event,
breaking Zustand selector referential equality. During streaming
(~60 events/sec), this caused every subscriber to re-render regardless
of which slice actually changed.
Now only clones fields the specific event type mutates. Also extracts
StatusRowContainer to isolate high-frequency useAssistantStatus
subscription, removes dead messageStreamStatesMap subscription from
ChatContainer, and narrows useAssistantStatus to only track last
assistant message parts.
MessageList renders: 1972 → 296 per streaming session (-85%).
* fix: null safety for sync state slices
Add defensive ?? {} guards on permission, question, session_status,
and message record access. Prevents crashes when child store state
is partially initialized during bootstrap.
* perf: dedup inflight SDK calls, extract concurrency util, delay PR tracking
Extract mapWithConcurrency to shared lib/concurrency.ts. Add in-flight
dedup for loadProviders/loadAgents to prevent concurrent duplicate SDK
calls. Delay initial PR background tracking by 5s to reduce startup
CPU burst.
* fix: header session lookup across all child stores
Session title and context panel click failed when session belonged to
a different directory than the current child store. Fall back to
getAllSyncSessions() to search all initialized stores.
* chore: bump @opencode-ai/sdk to 1.3.5
* docs: add sync event handling guide
* Optimize session prefetch and improve delete/archive UX
- Add settlement delay to session prefetch to avoid race conditions on
rapid session switches
- Reduce git diff prefetch and session cache limits for better performance
- Implement optimistic UI updates for session delete/archive operations
with proper rollback on failure
- Wire session prefetch hook into SessionSidebar with sync integration
* Add file content cache and sync optimizations
- Wrap FilesAPI with in-memory LRU cache for file content with dual
constraints (entry count and byte size)
- Optimize chat timeline scroll restoration using useLayoutEffect
- Preserve React references in message and part arrays to prevent
unnecessary re-renders when prepending history
- Add session prefetch TTL cache to prevent redundant fetches
- Integrate session prefetch cache clearing with eviction flow
* Improve session sidebar error handling and add diff prefetch filtering
Load active and archived sessions independently using Promise.allSettled
to prevent one failure from blocking the other. Add retry logic to session
API calls and skip large files during diff prefetch to improve performance.
* Replace sendMessage with optimisticSend wrapper
Introduces optimistic UI updates for normal chat messages to provide
instant feedback. Messages appear immediately in the UI while the API
call executes in the background, with automatic rollback on errors.
* perf: split stores, proper optimistic send, fix revert/directory bugs
- split session-ui-store into voice/input/selection/viewport stores
to reduce subscriber re-evaluation during streaming
- wire optimisticSend through useSync shadow Map infrastructure
matching OpenCode's pattern (no heuristic part detection)
- port OpenCode Identifier.ascending ID format for correct sorting
- pass messageID to promptAsync to prevent duplicate messages
- fix worktree directory not propagating to session actions
(dynamic dir() via opencodeClient.getDirectory)
- fix setCurrentSession accepting directoryHint for new sessions
- fix revert not hiding messages (session limit was 5, bumped to match loaded count)
- fix revert optimistic message removal from store
- fix load-more flicker (useLayoutEffect scroll compensation)
- add prefetch TTL cache, file content LRU cache
- add session prefetch for adjacent sessions
- add instant archive/delete (optimistic before SDK call)
- migrate legacy window.__zustand_session_store__ to session-ui-store
- add retry + independent error handling for archived sessions
- add AGENTS.md performance rules
* perf: startup optimization — dedup, caching, light git status, diff rendering gates
- defer diff prefetch to git tab open, reduce concurrency 4→2, skip >500 changed lines
- cap project git checks concurrency (2), directory status probe (3)
- dedup provider/agent loading, github auth, worktree list (in-flight + TTL caches)
- delay PR tracking 5s, cache 403 search failures per-repo
- coalesce settings PUT (200ms debounce), cache settings GET (2s TTL)
- cache canonical directory resolution (60s TTL)
- persist missing directory status to localStorage (10min TTL)
- light/heavy git status: polling skips numstat+line counting+rev-list
- large diff rendering gate (>500 lines → "render anyway" button)
- tokenization degradation for >500KB files in Pierre
- parallelize main.tsx pre-render awaits
- batch sidebar file tree expanded paths restoration (3 at a time)
- remove bare useConfigStore() subscription in AgentsPage
- sync worktree sandboxes to OpenCode SQLite DB
- fix RightSidebarTabs ternary → explicit tab matching
- defensive guards on sync state (session_status, permission, question, message)
* fix: add defensive guards on remaining sync state field accesses
guard session_status, permission, message, todo, part, config with ?? {}
in useDirectorySync selectors, session-cache, and bootstrap
* fix: add missing directory dep to useCallback in use-sync.ts
* fix: preserve diffStats when light-mode polling overwrites status
* perf: optimize startup git status polling and diff rendering
Preserves diff stats when lightweight polling updates repository status
Reduces startup overhead with smarter git polling and store updates
Adds detailed optimization and migration docs for next performance steps
* fix: keep chat diff stats stable during git status updates
Prevents lightweight git polling from dropping diff statistics
Keeps MessageList diff indicators consistent while status refreshes
Improves reliability of git-aware chat rendering
* fix: user animation replay, queued message variant, startup provider loading
- consume animation ID after first play to prevent re-animation
on neighbor assistant message completion
- capture send config (model/agent/variant) at queue time matching
OpenCode's FollowupDraft pattern instead of re-resolving at send time
- replace one-shot startup recovery effect with polling interval
that retries every 2s until providers and agents load
- fix optimistic bridge to avoid re-render loop (stable ref wrappers)
* chore: update tauri to 2.10.3 and all plugins to latest
- tauri 2.9.4 → 2.10.3

refactor(chat): complete turn-based pipeline and stabilize streaming, scroll, and tool UX (#629)
* refactor: add canonical turn projection pipeline for chat Centralizes turn/activity/summary derivation, migrates render consumers to shared projection sources, and adds projector regression coverage for retries, malformed parent fallbacks, and activity segmentation. * refactor: stream assistant text live in turn-first render path * refactor: complete phase-3 turn timeline history/navigation * refactor: complete phase-4 turn pipeline cutover Remove legacy grouping adapters and lock key edge cases with executable regression tests so turn-centric rendering stays stable across retry/history/navigation flows. * fix: align chat history loading path with opencode parity * fix: stabilize chat streaming and reduce render churn * feat: add blurIn streaming text animation and smooth lerp-based auto-scroll Streaming markdown now uses Streamdown blurIn animation (150ms, ease-out) for per-word reveal Auto-scroll during streaming uses continuous exponential smoothing (lerp) instead of restarting spring animations One-shot scroll-to-bottom (button click) uses motion spring for natural deceleration * fix: respect user scroll-up during streaming and re-pin on scroll back to bottom * fix: stabilize activity stream and tool progress rendering Activity now stays chronologically consistent and avoids duplicate reasoning/justification. Tool rows show running state and duration earlier with smoother pending behavior. Removed legacy trim/timestamp paths to prevent message drops and simplify Activity UI. * fix: reverted regression of revert functionality * fix: stabilize chat activity layout and tool progress behavior Stopped user messages from re-animating when new user messages appear. Made Activity and aggregated tool rows wrap inline consistently without misaligned headers/icons. Fixed tool part matching so duration and shine no longer reset across pending/in-progress status updates. * fix: restore activity mode behavior and stabilize tool rendering Re-enabled Collapsed/Summary/Detailed/Changes defaults for Activity and tool expansion. Fixed tool row wrapping/alignment, removed user fade re-animations, and disabled FadeInOnReveal animations. Improved tool status handling to reduce timer/shine resets and made reasoning bold render as normal text. * refactor: simplify chat tool and message rendering Replace activity-group rendering with flat inline part rendering Remove obsolete tool output and justification activity settings Keep user message animation and improve edit/apply-patch file path headers * style: narrow chat and composer columns equally * fix: Tool status checks and abort flow regression * fix: improve multi-file apply patch header rendering * fix: make timeline message jump scroll to selected chat entry Conversation Timeline clicks now reliably scroll to the selected message in chat Timeline dialog waits for navigation result before closing to avoid silent failures Chat message scrolling now resolves the active chat scroller consistently * chore: remove branch-added chat tests and clean lint leftovers Removes newly added chat and message test files from this branch Fixes lint blockers in ProgressiveGroup, ToolPart, and messageStore Keeps type-check, lint, and build passing after cleanup * fix: keep composer status row closest to the input Status/todo row now renders below queued messages and attachments. Linked GitHub issue/PR chips stay above status so input context order is consistent. Improves chat composer readability while assistant is working. * fix: disable assistant header animations and polish chat status behavior Assistant message header now renders without transition effects Removed a lint issue from the working placeholder props Chat status and message flow updates improve consistency during active turns * feat: increase bottom spacer in mobile chat for better scrolling * feat: add sorted chat mode with progressive activity rendering Adds global chat render mode settings for sorted and live behavior Renders non-stop assistant output in Activity as messages complete Disables streaming text animation in sorted mode and restores classic reasoning/justification blocks * fix: stabilize chat timeline navigation and older history loading Prevents auto-loading older history from scroll and keeps loading behind the button Fixes timeline jump-to-message behavior that snapped back to the bottom Reduces chat list flicker and empty-state glitches on large session pagination * fix: stabilize sorted activity text and hide reasoning timers Prevented sorted justification from appearing before message completion by requiring explicit non-stop finish. Removed duration values for sorted Thinking and Justification blocks. Kept smooth sorted auto-follow behavior tuned to reduce bottom-jump jitter. * refactor: simplify chat tool rendering paths and add parts docs Centralized tool icon mapping into a shared presentation helper used by grouped and expandable rows. Removed static-tool-specific branches from ToolPart to keep it focused on expandable tools. Added a new DOCUMENTATION.md explaining where to change tool descriptions and rendering behavior. * feat: enhance event stream handling for message parts - Refactor event key building functions to improve clarity and reduce redundancy. - Introduce `applyPartDelta` method in message store for handling delta updates to message parts. - Update `useEventStream` to utilize the new `applyPartDelta` method for processing incoming deltas. - Enhance text extraction logic to accommodate new part types and improve merging behavior. - Implement logic to skip delta-driven updates for ongoing text/reasoning parts to prevent overwriting. - Adjust server-side text merging logic to handle trimmed text comparisons and improve consistency. * feat: enhance OpencodeService with delta handling and stale delta management - Introduced globalSseStaleDeltas to track stale deltas. - Added methods to generate keys for delta and updated part events. - Updated global SSE loop to skip processing stale deltas. - Refactored global SSE event handling to improve performance and reliability. refactor: remove unused streaming part handling in messageStore - Eliminated streaming part queue and associated logic. - Simplified message merging logic by removing redundant checks. - Streamlined message handling to improve clarity and maintainability. chore: clean up unused streaming text normalization functions - Removed deprecated functions related to streaming text identity and merging. - Simplified normalizeStreamingTextPayload to focus on current functionality. * refactor: simplify streaming event passthrough Use SDK-native global event streaming in the UI client Remove dead server-side SSE normalization helpers Keep streaming payloads closer to upstream behavior * revert: remove message memory settings UI Drop the restored message memory settings screen Keep session settings focused on current defaults Preserve chat history limits as internal behavior * feat: add compact collapsed Activity preview in sorted mode Collapsed Activity now shows a live preview of the latest 7 entries Older activity rows roll up behind a +N more indicator The +N more indicator is clickable to expand the full Activity * fix: adjusted activity changed files text prominence * fix: make sorted mode snap to bottom when not streaming * perf: show chat scrollbar only on user-driven scrolling Chat scrollbar now stays hidden during automatic follow-to-bottom Scrollbar visibility is gated by real user scroll intent Reduced scroll overhead by removing timer-based intent tracking * refactor: align web and vscode session activity streaming Route VS Code SSE through SDK-based proxy flow Restore controlled web session activity tracking and cooldowns Keep chat activity behavior consistent across runtimes * fix: adjusted muted foreground themes color * fix: stabilize session activity and attention updates Keep streamed chat state in sync as sessions complete Restore reliable attention indicators for inactive sessions Tighten server and UI event handling for chat updates * feat: add chat render previews and file icon visibility setting Added animated chat render mode previews in Chat settings. Added a new toggle to show or hide file icons across tool rows. Persisted chat render, activity, and mermaid modes to shared settings file. * fix: update default GitHub OAuth client ID Use the new OpenChamber org GitHub OAuth app ID by default. Keep web server and VS Code auth defaults in sync. * fix: sync chat settings across VS Code chat views Broadcast settings changes to both sidebar and editor chat webviews. Apply synced settings in each webview via shared settings refresh. Ensures chat render mode updates appear immediately in editor tabs. * fix: stop writing session folders file in VS Code workspaces Disable disk persistence for session folders in VS Code webview runtime Keep session folder state in VS Code/webview storage instead of project files Preserve existing behavior for non-VS Code runtimes * style: polish expanded tool panels and bash output readability Removed extra borders/labels in expanded tool cards for a cleaner UI Added softer scroll shadows and full-height decorative activity line Switched bash command/output to code-style typography with tighter spacing * feat: add default-open tool controls for chat activity Added Chat settings toggles to open Bash and Edit tools by default Default-open behavior now applies across both sorted and live activity rendering Users can still manually collapse default-open tools, plus bash output height was reduced * fix: align chat loading skeleton with message layout Match skeleton width and horizontal alignment to chat message column Add one-line tool-style skeleton rows with subtle circular placeholders Increase top spacing so loading state no longer touches chat header * fix: prevent blank screen when adding inline diff comments Sanitize persisted inline comment drafts to ignore invalid data Harden diff annotations against malformed line numbers Fail safely when annotation updates error instead of crashing the view * fix: streamline VS Code archived sessions sidebar Show archived sessions in VS Code only for the active workspace directory.
