Company-mode UIs became unusably slow once work items and transcripts
grew. Three presentation-layer fixes, none touching work progression:
- App.tsx: buffer assistant_delta/thinking_delta store writes per task
and flush every 80ms instead of once per token; any non-delta event
for the same task flushes first so draft/clearDraft ordering is
byte-identical. The unconditional per-event setUiTick (whole-app
re-render per websocket event) is now a 300ms trailing throttle.
- PhaserGame: display:none does not stop requestAnimationFrame, so the
office scene kept burning CPU on every other page. The loop now
sleeps when the office page is hidden and wakes (with a parent-bounds
refresh) on return; bridge writes stay synchronous so no state is lost.
- Kanban collab_sync debounce 0.2s -> 1.5s: the broadcaster is a
trailing coalescer, so the final board state still always ships; each
fire is a full-project snapshot build, which at 5/s dominated backend
CPU on large projects. CommsPanel poll 8s -> 30s (comms_state_dirty
push already drives freshness) and its interval no longer pins a
stale onRefresh closure.
Verified: tsc + vite build, App.test.tsx / workItemSessions structural
tests, backend suites (company_review_flow incl. debounce push test,
kanban_push_runtime, actor_runtime_company_mode, task_mode_contract,
work_item_transition — 119 green), and canvas_smoke e2e against a real
server with zero console errors.

Office canvas fixes:
- Lazy-create the Phaser game via ResizeObserver on the first non-zero
layout instead of creating it inside the display:none office page with
inline px fallback sizes. Phaser's RESIZE-mode 500ms parent poll has no
zero guard, so the old path shrank the canvas to 0x0 (blue-black screen)
and later restored it to a stale wrong size (clipped office).
- On unhide, re-measure with scale.getParentBounds() before scale.refresh();
plain scale.resize() is clobbered by the stale cached parentSize in
RESIZE mode.
- Fix whole-game freeze when clicking an office card: camera effects
resolve ease names via EaseMap, which has no 'Cubic.Out' key, leaving
effect.ease undefined and killing the RAF loop with a per-frame
TypeError. Use 'Cubic.easeOut' for cam.pan in panToOffice/resetCameraView.
- Bound GameBridge queues (latest snapshot supersedes, event queue capped)
since game creation is now deferred until the Office page is first opened.
Sidebar:
- Add a collapse/expand handle on the canvas/sidebar boundary with a 220ms
grid transition; state persists in localStorage. The canvas follows the
column change automatically through the ResizeObserver path. Stacked
(<=1024px) layout collapses the bottom panel and moves the handle to the
bottom edge.
README:
- Add Simplified Chinese translation (README.zh-CN.md) with a language
switcher in both files; fix stale TOC entries in the English README.
