Six builtin defaults (Code Reviewer, Debugger, Refactorer, Architect,
Security Auditor, Prompt Builder) with no model field so session.model
wins. Project root AGENTS.md parsed on demand with mtime cache; when
present, only its agents are shown. sessions.agent_id resolves per turn
into effective system prompt, temperature, and a tool whitelist applied
in inference. AgentPicker mounts in the ChatInput toolbar; SettingsDrawer
agent surface deferred to Batch 7.
- ChatInput: e.nativeEvent.isComposing early-return added (CJK IME
safety — first Enter of a composition no longer submits). Bare-Enter
send path gated by !isMobile so mobile inserts a newline; send is
button-only. Cmd/Ctrl+Enter and Shift+Cmd/Ctrl+Enter retained as
desktop secondary bindings. Placeholder is now viewport-aware. Outer
wrapper gets paddingBottom: env(safe-area-inset-bottom) so iOS home
indicator doesn't overlap.
- MessageBubble: ActionRow buttons (Copy / Regenerate / Fork / Trash)
bumped to max-md min-h/min-w 44px; opacity-100 on mobile so actions
don't hide behind a hover-to-reveal pattern. User bubble and
assistant content wrapper gain break-words + min-w-0 so long
unbreakable strings (URLs / paths) wrap rather than blowing out
the column on narrow viewports.
- ChatPane: queued-message dropdown + close X + Stop-generating button
hit max-md 44px sizing.
- ChatTabBar: per-tab X, +/History/Close-pane action buttons hit
max-md 44px. Tab close X is force-visible on mobile (no
hover-to-reveal).
- M8: CodeBlock / Markdown tables / ToolCallCard already wrap
overflow-x-auto pre-existing — no source change needed there; the
break-words + min-w-0 additions above are the new defensive layer.
Adds a floating popover above the chat input showing current
context-window usage. Modeled on Paseo's tracker.
- New hook useChatContextStats(chatId, messages) finds the latest
assistant message in the chat with both ctx_used and ctx_max set,
computes percent, and returns null when data unavailable.
- New component ChatContextPopover renders a small card with the
"Context window" label, big percent, and "used / max tokens"
subline. Hidden when stats is null.
- Color thresholds: <60% muted, 60-85 amber, >85 destructive.
- Not a portal — absolutely positioned inside a new relative
wrapper around ChatInput in ChatPane.tsx, so it's pane-local
(multi-pane safe).
- Live updates via the existing messages-array dependency.
- No API / schema / WS changes.
Feature 1 — Tab close menu (pure local pane state, no API):
- ChatTabBar context menu: Rename / sep / Close / Close others / Close to right / Close all
- Workspace bulk-tab primitives: closeOtherTabs, closeTabsToRight, closeAllTabs (manipulate panes[].chatIds, no fetch)
- Drop in-bar Delete; landing card's name-typed Delete is the canonical destructive path
Feature 2 — Chat archive + delete:
- chats.status vocabulary aligned with projects ('open' | 'archived'); DROP old inline CHECK, UPDATE 'closed' → 'archived', ADD new named chats_status_chk
- POST /api/chats/:id/archive (204) + POST /api/chats/:id/unarchive (200) + GET /api/sessions/:id/chats?status=archived; DELETE publishes chat_deleted; PATCH simplified to name-only
- 3 new WS frames: chat_archived, chat_unarchived, chat_deleted (renamed from chat_closed)
- Same dedup discipline: server-only publish, no local sessionEvents.emit in client
- SessionLandingPage: right-click ContextMenu (Open / Rename / Archive / sep / Delete-destructive), inline rename, archive confirm dialog, delete dialog with name-typed Input gated until typed text === chat.name, Archived chats collapsible section with Restore
- Card-level Archive + Delete icon buttons reusing the same dialog state setters; stopPropagation on both so card click still opens the chat; archived cards keep only Restore
UX — chat content width cap:
- ChatPane content (MessageList, queue chips, stop button, ChatInput) wrapped in inner max-w-[1000px] mx-auto w-full so messages center; outer border-t / scroll containers stay full-width so pane chrome and backgrounds remain edge-to-edge
- No new deps, no media queries (narrow viewports collapse to width naturally)
Session 1:N Chat data model with backfill. Workspace switches to client-side
multi-tab pane management. Right-rail file browser with float-over viewer and
click-drag line selection replaces FileBrowserPane. Adds /compact streaming
summarizer (respects compact markers in context builder), force-send (cancels
in-flight, persists partial as 'cancelled', awaits cancellation completion via
deferred Promise + 5s timeout), message queue, stop generation, chat
auto-rename, session archive/unarchive with Closed Sessions section on repo
landing page. CHECK constraints on sessions.status, messages.role,
messages.status with KEEP IN SYNC comments tying to MESSAGE_ROLES /
MESSAGE_STATUSES const arrays. Deletes dead pane routes/hook and the
api.panes.* client block.
