- Add #chat-area wrapper (flex row) in #main to host messages-wrap + nav-sidebar side by side
- Add <nav id=nav-sidebar> with .nav-sidebar-list of clickable .nav-anchor elements
- New shared-nav-sidebar.js: AcbNavSidebar API (rebuild, onNewMessage, setEnabled, isEnabled, applyEnabledState)
- IntersectionObserver highlights active anchor for currently visible message
- Click anchor -> scrollIntoView({ behavior: smooth, block: center }) + brief .nav-highlight flash
- Per-agent dot colours via stable authorId->colour mapping (5-colour palette)
- Toggle via Settings > UI Preferences checkbox (localStorage acb-minimap-enabled, instant, no restart)
- acb-modal-shell.js: renderUiPreferences() + _attachMinimapToggle() + AcbModalShell.syncMinimapCheckbox()
- shared-modals.js: openSettingsModal() syncs checkbox from localStorage on open
- Responsive: sidebar hidden at <=1100px via @media
- ?v=N+1 bumped for acb-modal-shell.js (v4) and shared-modals.js (v5)
- 13 Vitest tests (103 total, 0 regression)
…in messages-wrap)
- Replace absolute emoji rail with fixed-width nav-sidebar column - Add #chat-area flex wrapper (messages-wrap + nav-sidebar side by side) - nav-entry: emoji + author name + time, hover/active states, clic jump - IntersectionObserver highlights visible messages - Responsive: hidden below 1000px, toggle via Settings localStorage - 104 Vitest tests passing
- #messages-wrap: flex-direction row (messages-scroll + nav-sidebar) - New #messages-scroll wrapper handles overflow-y: auto (scroll) - #messages: layout only, no overflow - scrollBottom() and scroll-top btn now target #messages-scroll - IntersectionObserver root = #messages-scroll - 104 Vitest tests passing
- After buildSidebar(), compute msg-sys-prompt height and set sidebar padding-top so entries start at the first msg-row - On scroll, update padding-top dynamically so alignment tracks - 104 Vitest tests passing
- Add #sys-prompt-area (full-width, flex-shrink:0) above #chat-body - #chat-body = flex row: #messages-scroll + #nav-sidebar - appendBubble: seq=0 injected into #sys-prompt-area, not #messages - resetThreadSelection: clear #sys-prompt-area on thread change - Remove dynamic padding-top hack from shared-nav-sidebar.js - 104 Vitest tests passing
- System prompt collapsed by default on thread open - Minimap: ignore initial IntersectionObserver batch (300ms guard) to avoid all entries showing as active on load - Minimap click: scroll messages-scroll to row.offsetTop - 12px for precise top-aligned navigation instead of block:center - 104 Vitest tests passing
- System prompt opens expanded when thread has no messages - Auto-collapses when first msg-row is appended to #messages - If already collapsed (user manually closed), no double-toggle - 104 Vitest tests passing
