* 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.

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.

instant feedback. Messages appear immediately in the UI while the API
call executes in the background, with automatic rollback on errors.

- replace one-shot startup recovery effect with polling interval
that retries every 2s until providers and agents load
