Remove .pill-trigger CSS class and restore the idiomatic Tailwind v4
@theme approach: --text-pill in @theme generates the text-pill utility.

The @theme --text-pill token and text-[8px] arbitrary value both
failed to apply at dev time due to @tailwindcss/vite not generating
the utility rule during HMR. Use a plain .pill-trigger CSS class
in styles.css instead, which is always available regardless of
Tailwind's JIT scanner behavior.

The arbitrary text-[8px] class was not being generated by the
Tailwind v4 Vite plugin at dev time. Register --text-pill in
@theme so text-pill becomes a first-class utility that is always
generated. Uses 0.5rem (8px) with line-height 1.

Add explicit leading-none alongside text-[8px] so both font-size
and line-height shrink, making the size reduction visually apparent.

Reduce font to text-[8px], restore icons to size-2.5 for legibility,
and bump padding to px-1.5 py-0.5 so icons aren't flush with the
pill border.

Shrink padding (px-2 py-1 → px-1.5 py-0.5), font (12px → 11px),
gap (1.5 → 1), icon size (3 → 2.5), and model name max-width
(140px → 120px) on all four pill trigger buttons. Dropdown popovers
remain unchanged.

The useCallback for handleCreateScratchpad was placed after the early
return for the loading state, causing React to see a different number
of hooks between the initial render (workspace undefined) and subsequent
renders. Move it before the guard and add a null check inside instead.

PrismJS's CJS global state is fundamentally incompatible with Vite's ESM
dev mode, causing missing language support (~40% of dropdown languages)
and fragile loading hacks (optimizeDeps, global assignment).
Replace the entire Prism integration with highlight.js/lib/common which
is ESM-native, has no global state, and covers all 22 dropdown languages
out of the box (~37 common languages included).
Implementation:
- Custom CodeHighlightPlugin using hljs.highlight() for tokenization
- HTML parser extracts flat tokens from hljs output (handles nested spans)
- Token type mapping from hljs scopes to Lexical codeHighlight theme keys
- Selection preservation via absolute character offset save/restore
- Re-entrancy guard prevents infinite transform loops
- Removed @lexical/code-prism import and Vite optimizeDeps workaround

Remove the prismSetup module that imported prismjs directly — it
caused Vite to pre-bundle prismjs into a separate chunk from
@lexical/code-prism, breaking the CJS require chain. Language
components tried to call Prism.languages.extend() before the base
grammars were available, crashing the app.
Instead, add optimizeDeps.include for prismjs and @lexical/code-prism
so Vite pre-bundles them together, preserving the correct CJS
evaluation order within a single chunk.

The previous approach imported prismjs component files directly in
MarkdownComposer.tsx. In Vite dev mode, each component is served
as a separate ESM module whose IIFE references a bare 'Prism' global
that doesn't exist yet, crashing the app.
Fix: create a dedicated prismSetup module that imports prismjs and
assigns globalThis.Prism, then import it from the renderer entry
point (main.tsx) before any component that loads @lexical/code-prism.
ESM evaluation order guarantees the global is set before the
tokenizer captures its reference.

- Register CodeHighlightNode in the editor node set
- Add CodeHighlightPlugin that calls registerCodeHighlighting
- Map 20+ Prism token types to mc-tok-* CSS classes with dark theme colors
- Explicitly import prismjs + language components and set globalThis.Prism
before @lexical/code-prism loads, fixing a Vite dev-mode race where
the CJS shim could initialize the tokenizer before the global was set
- Added @types/prismjs for type checking

The imperative approach inserted overlay elements directly into
Lexical-managed CodeNode DOM elements. Lexical's MutationObserver
detected the foreign DOM nodes, reconciled them away, which triggered
update listeners that re-inserted them — causing an infinite loop
that froze the app.
The new approach renders overlay elements via React, positioned
absolutely in a pointer-events:none container that sits over the
content editable. Overlay positions are computed from each code
element's bounding rect and updated via requestAnimationFrame on
editor updates and scroll events. This avoids all Lexical DOM
mutation and eliminates the freeze.

Language selector:
- Replaced toolbar dropdown with an imperative overlay rendered
directly inside each code block's DOM element
- Overlay uses contentEditable='false' + position:absolute at the
top-right of the code block, styled as a compact native select
- Plugin re-inserts overlays after each Lexical reconciliation to
survive DOM diffing
Code block insertion:
- toggleCodeBlock now inserts a trailing paragraph after the code
block when it would otherwise be the last element, so the user
can always type regular text below a code block

When the cursor is inside a code block, the formatting toolbar shows
a language dropdown (22 languages). Selecting a language updates the
CodeNode, which the markdown serializer writes as the fenced code
block language tag (e.g. \\\ ypescript).
A CodeBlockLabelPlugin syncs a data-code-language attribute on each
code block element so CSS ::before shows the friendly language name
as a small label at the top of the block.

- Increase editable min-height from 40px to 52px and padding from 8px
to 10px so the send button (32px + 8px bottom offset) has 12px
clearance from the toolbar border instead of 0px
- Add display: block to .mc-code-block — Lexical CodeNode renders as
<code> which is inline by default, causing border/padding to split
visually across lines instead of forming a proper block
- Revert empty code block to code.select() without synthetic TextNode

- Move send button into MarkdownComposer children slot so it positions
relative to the editor content area, not the full container
- Always create a text node when inserting a code block to prevent
Lexical from rendering a split/empty code block artifact

Replace the plain <textarea> in ChatPane with a full WYSIWYG
markdown composer built on Lexical 0.42.0.
Composer features:
- Rich text editing with inline formatting (bold, italic, code)
- Block-level elements: headings, bullet/numbered lists, code blocks,
blockquotes, links via markdown shortcuts (e.g. ## , - , \\\)
- Formatting toolbar with active-state indicators
- Markdown paste auto-import when the editor is empty
- Enter to send, Shift+Enter for newline (matches prior behavior)
- Disabled state syncs with session busy/config states
- Serializes to markdown on submit via the backend helpers
Files:
- New: MarkdownComposer.tsx (Lexical editor, toolbar, internal plugins)
- Modified: ChatPane.tsx (swap textarea for MarkdownComposer, simplify state)
- Modified: styles.css (add markdown composer theme classes)

- Add CSS styling for selected edges (indigo highlight with glow)
- Enable orchestrator↔agent connections in group-chat mode
- Downgrade disconnected-agent validation from error to warning
- Rename addHandoffEdge to addEdge (generic for all modes)
- Add tests for group-chat connection rules

Extend edge deletion to group-chat orchestrator↔agent edges in addition
to handoff agent↔agent edges. Structural edges (user-input/output,
distributor/collector) remain non-deletable across all modes.
Sequential, concurrent, and single modes keep fully structural topologies
with no user-deletable edges.

- Enable Delete-key removal of agent nodes on the canvas; system nodes
remain non-deletable. Removals route through the authoritative
removeAgent path which prevents deleting the last agent.
- Stack Model and Reasoning selects vertically in the inspector panel
so they fit within the 320px-wide column without truncation.
- Add right padding (pr-36 / 144px) to the editor header so the Save
and Delete buttons clear the Windows title-bar overlay controls.

- Color-code edges by semantic role: structural edges (system↔node) in
muted zinc, agent-to-agent edges in indigo for clear visual separation
- Switch from smoothstep to bezier curves for smoother, more natural
edge routing that reduces right-angle overlaps
- Stagger agent nodes at alternating X offsets in concurrent, handoff,
and group-chat layouts so parallel fan-out/fan-in edges take distinct
bezier paths instead of stacking
- Increase spacing in all layouts to give edges more room
- Add dagre-powered auto-layout button (top-right of canvas) that
computes optimal left-to-right hierarchical node positions
- Add 2 new tests for auto-layout across all orchestration modes

Hide the target (left) handle on SystemNode and AgentNode so each node
displays only one visible circle. The directional arrow marker on edges
communicates flow direction, halving the visual handle count.
- user-input: source handle on right (visible)
- user-output: target handle on left (visible)
- all others: source handle on right (visible), target on left (hidden)

- Add ArrowClosed markers to all graph edges for clear directional flow
- Replace generic Bot icon with AI provider logos (OpenAI, Anthropic,
Google) on agent nodes, inferred from the agent's model id
- Show model display name as subtitle on agent nodes (e.g. 'GPT-5.4',
'Claude Opus 4.5')
- Thread availableModels catalog from PatternEditor through canvas to
resolve friendly model names; falls back to raw model id
- Add 3 new tests for arrow markers, provider icons, and model labels
Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
- Hide input handle on User Input nodes and output handle on User Output
nodes (separate userInputNode/userOutputNode node types)
- Enable edge deletion in handoff mode only (Delete key or React Flow UI);
only agent-to-agent edges are deletable, structural edges are protected
- Block all edge mutations (add/delete) in concurrent and group chat modes
- Add agent as disconnected node without auto-rebuilding the graph
- Add sequential reorder controls (↑↓) in the inspector panel with
position/order swap and automatic edge rebuilding
- Replace circular group chat layout with vertical column to prevent
bidirectional edge crossings
- Tighten handoff layout spacing so edges between triage and specialists
don't overlap nodes
- Use smoothstep edge type for cleaner edge routing across all modes
- Add 6 new tests covering reorder, disconnected add, edge deletion rules,
and node type assertions

Replace the flat agent list and static flow diagrams in PatternEditor with
an interactive React Flow canvas backed by the authoritative PatternGraph
model. Users can now see and manipulate orchestration topology visually.
Changes:
- Add @xyflow/react (React Flow) as a canvas library
- Create patternGraph view-model layer for graph-to-canvas projection
- Create GraphNodes with custom system/agent node components
- Create PatternGraphCanvas with drag, connect, and selection support
- Create PatternGraphInspector for selected node/agent details
- Rewrite PatternEditor with split layout: canvas + inspector sidebar
- Add dark theme CSS overrides for React Flow
- Add 11 tests covering view-model projection, connection rules, and
graph mutation helpers
- Update ARCHITECTURE.md to reflect the new renderer graph boundary
The canvas projects PatternGraph into React Flow nodes/edges. Handoff mode
supports drawing new agent-to-agent edges interactively. Node positions
persist to the graph on drag completion. Agent editing moves from inline
forms to the inspector panel on node selection.
