Adds animated reveals for file path tool descriptions
Keeps sorted mode tool animations working without extra chat gaps
Preserves file icons, truncation, and click behavior
Replace @remixicon/react with a shared Icon component that renders
via <use href> references to a single hidden SVG sprite. This reduces
DOM node count by replacing inline SVGs with lightweight references.
- Create Icon component with sprite injection (packages/ui/src/components/icon/)
- Migrate all 164 files from @remixicon/react to Icon component
- Auto-generate sprite data from remixicon bundle (scripts/generate-icon-sprite.mjs)
- Add bun run icons:generate to package.json
- Move @remixicon/react to devDependencies
- Add icon usage instructions to theme-system skill
The previous system layered three hooks (useScrollEngine, useChatScrollManager,
useChatTimelineController) with overlapping responsibilities, four parallel
ResizeObservers/MutationObservers, and six entry points to "scroll to bottom"
(force-flag combinations, persistent follow loops, materialization recovery).
This produced bugs where users could not break free of auto-follow during
streaming: scrollbar drag, keyboard scrolling and find-in-page were not
detected as user intent, and observers kept restarting the follow loop on
every DOM mutation.
The new architecture replaces the two low-level hooks with a single
useChatAutoFollow that owns scroll behaviour end to end:
- One state: 'following' or 'released'. No follow modes, no pin flags,
no marker pixels.
- One scroll writer: a lerp loop that runs only while the session is
streaming and state is 'following'. Idle sessions never write scrollTop
programmatically.
- One user-intent detector: wheel up, touch drag down, keyboard
(PageUp / Home / ArrowUp), pointerdown on the OverlayScrollbar thumb,
and explicit releaseAutoFollow() calls all flip the state to 'released'.
- A 1.2s grace period after explicit release: re-pin will not auto-engage
inside this window, so a small wheel up cannot snap the user back even
while they remain near the bottom spacer.
- Re-pin and the scroll-to-bottom button share the same threshold: the
height of the empty bottom spacer (10vh on desktop, 40px on mobile).
Released users see the button only after they have scrolled past the
spacer that already exists at the end of the chat.
- Save/restore of scroll position uses ratio mapping, debounced at 150ms
on user-driven scroll events; programmatic writes are masked via a short
window so they never persist as user positions.
- Container reattachment is detected via a useLayoutEffect probe over
scrollRef.current. Listeners and observers re-bind when ChatViewport
mounts after hydration or after the first message promotes a draft
session into a real chat.
- A pending-restore queue replays restoreSnapshot once the scroll
container appears, fixing the case where a hydrating session landed at
the top instead of the bottom.
Removed: useScrollEngine.ts, useChatScrollManager.ts, the persistent
follow loop with its own ResizeObserver+MutationObserver pair, the
materialization-recovery .finally resume that yanked idle users to the
bottom on transient sync gaps, and the openchamber:session-reselected
event (re-select still works through the existing onSessionSelected
callback). The openchamber:chat-force-scroll-bottom event remains for
synthetic-message paths like git-message generation.
Net change: ~1300 lines removed, two hooks replaced with one, one
observer pair instead of four.
