Bohdan TriapitsynandIuliia Ivashko c9e31a0e6c perf: harden sync architecture and modularize runtimes (#803)
* fix: added desktop app background throttling

* perf: add streaming debug metrics panel

- Show streaming performance metrics in the debug panel
- Auto-enable stream profiling while the panel is open
- Add JSON export for sharing UI and VS Code metrics

* perf: batch streaming updates more aggressively

- Buffer message deltas and metadata updates to cut render churn
- Skip no-op part updates before they touch the message store
- Fix the desktop debug panel shortcut binding

* perf: split streaming event handling and coalesce deltas

- Move streaming content events onto a dedicated fast path
- Defer non-critical stream side effects off the hot path
- Merge repeated message delta events before they reach the UI

* perf: isolate streaming rows from chat rerenders

- Memoize chat rows against render-relevant message changes only
- Read live assistant text directly from store to narrow streaming updates
- Split the active streaming entry from the stable message list path

* perf: streamline chat streaming and SSE proxying

- Reduce chat rerenders around the active streaming path
- Simplify server SSE forwarding to avoid duplicate proxy work

* fix: preserve the first streaming text chunk

- Show the initial text chunk immediately before batched deltas arrive
- Bypass batching for the first text or reasoning part update
- Keep later streaming updates buffered for performance

* perf: align streaming/render hot paths with opencode parity

* perf: harden turn/cache stability and stale delta suppression

* fix: stabilize chat rendering and disable timeline interactions

- Disabled timeline dialog access from shortcuts, commands, and chat input
- Reduced chat render churn by simplifying message list and turn staging behavior
- Improved session-switch stability to prevent update-depth crashes

* perf: track static message rerenders during streaming

* perf: reduce sorted-mode activity rerender fanout

* perf: reduce chat rerender fanout and add active-turn metrics

- Reduced sorted-mode rerender coupling by tightening turn context propagation
- Added a metric for static rerenders outside the active turn during streaming
- 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)

  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)
