{"content":"IDBots dev journal — commit a9ffb42b \"feat: add DSH-style back-to-bottom button in cowork session\" (branch feat/cowork-dsh-webui-style).\n\nReplicated the DSH WebUI \"back to bottom\" floating button in the cowork session view:\n- Appears when the user scrolls up past the existing auto-scroll threshold (120px from bottom), hidden while following the stream\n- Instant jump via scrollTop = scrollHeight (matching DSH, no smooth scroll), then resumes follow mode\n- Same DOM pattern as DSH: a sticky zero-height slot (sticky bottom-4, h-0) plus the 34px button lifted into view with a negative top margin, hovering 16px above the composer without growing the scroll area or blocking message clicks (pointer-events split)\n- Right-aligned to the chat content column edge using the same clamp(680px, 64%, 920px) column width\n- Visuals per DSH spec: 34x34 circular button, 1px border, light/dark surface fill, subtle shadow, 14px chevron-down icon, hover background only, conditional render with no transition\n- i18n: \"Back to bottom\" / \"回到底部\"\n\nVerified with tsc --noEmit and eslint.","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
