2026.2.26

Added

Testing Infrastructure (Vitest)

  • Vitest test runner — vitest + happy-dom + @testing-library/react + @vitest/coverage-v8 added.
  • Test config — new vitest.config.ts with @ alias resolution and focused coverage include list for core business-logic files.
  • Comprehensive test suite — added tests/ tree:
    • Unit tests: cron, chat utils, gateway client/store, sessions utils, tool policy, device auth, formatting, text direction, agent status/utils, config utils.
    • Integration tests: use-chat hook behavior.
  • NPM scripts — test, test:watch, test:coverage added to package.json.

Changed

CI/CD

  • GitHub Actions — CI now runs npm test after knip and before build.

Build/Repo Hygiene

  • Coverage artifacts — added coverage to .gitignore.

Gateway Client Types & Behavior

  • GatewayClientOptions — added connectFallbackMs?: number to support deterministic connect-fallback timing in tests.
  • GatewayClient.sendConnectSoon() — fallback timer now respects opts.connectFallbackMs (defaults to existing constant when not provided).

Chat Utilities

  • stripThinkingTags export — made public for direct unit testing of parser edge cases.

Fixed

Chat Core (use-chat.ts)

  • handleLoadMore streaming guard — early return when chat.runId !== null prevents message list corruption during active streaming (was: load-more replaced optimistic + stream placeholder messages → duplicate messages)
  • handleRetry busy guard — added isBusyRef.current check; prevents parallel chat.send calls during active streaming
  • handleAbort per-frame re-render — uses runIdRef.current instead of chat.runId closure; deps reduced to [client, selectedSession]; eliminates callback re-creation on every streaming delta
  • handleRetry consolidation — refactored to call executeSend instead of duplicating try/catch/request logic; removed fragile finally block (double setState on error path)
  • Blob URL leak on image compression failure — preview hoisted above try block; URL.revokeObjectURL(preview) called in catch
  • Settings schema migration — localStorage settings merged with DEFAULT_CHAT_SETTINGS constant; missing fields from older schema get correct defaults instead of undefined

Chat Utilities (chat/utils.ts)

  • Thinking block extraction — extractThinking now collects all thinking blocks and joins with \n\n (was: only first block, break on match)
  • Stateful regex footgun — removed /g flag from module-level FILE_BLOCK_RE constant; added at call sites via new RegExp(source, 'g')
  • Floating-point quality guard — compression loop guard changed from > 0.3 to > 0.31; avoids one extra compression pass from 0.30000000000000004 > 0.3
  • generateId uniqueness — fallback (no crypto.randomUUID) now uses crypto.getRandomValues hex; final fallback adds Math.random() suffix to Date.now() for same-millisecond uniqueness
  • replaceAll with /g regex — changed redundant replaceAll(new RegExp(..., 'g')) to replace(new RegExp(..., 'g'))

Gateway Store (gateway-store.ts)

  • Timer leak across connection cycles — compaction/fallback timer handles stored in module-level variables; clearStatusTimers() called in disconnect(); previous timers cleared before scheduling new ones
  • Silent eager-fetch errors — added log.warn for non-scope/permission errors in connect() catch block
  • Stale run indicator — increased STALE_RUN_MAX_AGE_MS from 30s to 120s; matches Gateway's minimum agent timeout for tool-heavy runs
  • Event handler indirection — STORE_EVENT_HANDLERS uses direct function references instead of arrow wrappers

Gateway Client (client.ts)

  • Reconnect jitter — secureRandomUnit fallback changed from deterministic 0.5 to Math.random(); prevents thundering herd when crypto.getRandomValues unavailable
  • Binary encoding APIs — reverted codePointAt/fromCodePoint to charCodeAt/fromCharCode in device-identity.ts; correct API for binary byte data (0-255)

Server (server/index.ts)

  • Removed openBrowser — deleted auto-browser-open feature (--open / -o CLI flag, CK_OPEN_BROWSER env, spawn import, Windows cmd.exe code path)

Changed

Code Quality

  • Complexity reduction — stripThinkingTags rewritten from regex state machine to manual parser (smaller functions, no global regex state); component JSX ternaries pre-computed as variables
  • Type safety — window.__CK_CONFIG__ access replaced with typed getRuntimeConfig() helper; navigator access via getBrowserNavigator() with NavigatorWithUAData type; (navigator as any) eliminated
  • Index keys eliminated — array index keys replaced with content-based stable keys in bubble.tsx, session-sidebar.tsx; IIFE pattern refactored to pre-computed keyedImages/keyedFiles
  • Base64 overhead comment — documented TARGET_SIZE * 1.37 as // Base64 overhead ratio (~4/3)

Deduplication

  • extractAgentId / sessionLabel — deleted from chat/utils.ts; sessionLabel added to sessions/utils.ts; imports updated in use-chat.ts and chat/index.tsx
  • Unused _settings param — removed from groupMessages; ChatSettings import removed from chat/utils.ts

Comment Cleanup

  • Removed 31 low-value comments (obvious restatements, redundant separator labels, self-documenting component names) across 16 files; preserved all security, protocol, and domain rationale comments
