The StreamingTextMerger (C#) and mergeStreamingText (TypeScript) contained
custom word-boundary heuristics that inserted spaces between streaming deltas
based on incorrect assumptions. Two bugs caused mid-word spaces:
1. Unconditional space insertion when incoming delta started with uppercase or
digit characters, breaking acronyms (MDA -> M DA, UAG -> UA G)
2. LooksLikeWordBoundary using global token counts that fired on nearly every
mid-word token split (writable -> wr itable, fragile -> frag ile)
Both upstream projects (Copilot SDK and Agent Framework) use simple string
concatenation for delta accumulation. LLM streaming tokens natively include
whitespace when needed, so no boundary detection is required.
Removed all boundary heuristic methods and replaced with plain concatenation.
Kept overlap detection and snapshot handling for event redelivery scenarios.

For builder-based orchestration modes (group-chat, handoff), the loop edge
maxIterations, workflow settings.maxIterations, and mode-specific settings
(e.g. groupChat.maxRounds) were independently editable but only the mode
settings controlled runtime behavior. This caused confusion when changing
one did not update the others.
Changes:
- Add syncBuilderModeEdgeIterations() to keep loop edge maxIterations in
sync with the authoritative mode settings for builder-based modes
- Wire sync into normalizeWorkflowDefinition so edges are consistent on
load/normalization
- Update scaffoldGraphForMode to accept optional settings instead of
hardcoded iteration values (4 for handoff, 5 for group-chat)
- Sync settings.maxIterations <-> groupChat.maxRounds bidirectionally
when either changes in the UI
- Make loop edge controls read-only in the graph inspector for
builder-based modes with explanatory text
- Add 8 consistency tests validating built-in workflows, scaffold
behavior, and normalization sync

The forward edges from triage to specialists participate in cycles
(triage→specialist + specialist→triage), so they must be marked with
isLoop, condition, and maxIterations to pass validation.
Fixes the Handoff Support Flow template and scaffoldGraphForMode()
for handoff mode. Updates the corresponding test expectation.

- Delete src/shared/domain/pattern.ts and all pattern-specific renderer
components (PatternEditor, NewSessionModal, pattern-graph directory,
patternGraph lib) and their tests
- Migrate all renderer imports from @shared/domain/pattern to
@shared/domain/workflow (ReasoningEffort, reasoningEffortOptions,
WorkflowOrchestrationMode, AgentNodeConfig, WorkflowDefinition)
- Update App.tsx: remove workflowToPattern bridge, createDraftPattern,
NewSessionModal; sessions now created directly with default workflow
- Update ChatPane, ActivityPanel, Sidebar to accept WorkflowDefinition
instead of PatternDefinition and derive agents/mode from workflow
- Update SettingsPanel: remove PatternsSection nav item, pattern editing
state, and pattern-related props; update text references
- Update RunTimeline and modeAccent/modeVisuals records to use
WorkflowOrchestrationMode (drop magentic mode entry)
- Update sessionActivity.ts to use generic agent interface

Remove the invented code-executor node type entirely. Rename
function-executor to invoke-function to match Agent Framework's
InvokeFunctionTool declarative action. Update InvokeFunctionConfig to
use functionName, arguments, requireApproval, and resultVariable
properties matching the upstream schema.

Introduce a workspace-level agent library that allows users to define
agents once and reference them from multiple orchestration patterns.
Domain model:
- Add WorkspaceAgentDefinition type with name, model, instructions, etc.
- Extend PatternAgentDefinition with optional workspaceAgentId and overrides
- Add resolution helpers that merge workspace agent base with per-pattern overrides
- Extend WorkspaceSettings with agents array and normalize on load
IPC & main process:
- Add saveWorkspaceAgent/deleteWorkspaceAgent IPC channels and handlers
- Resolve workspace agent references in buildEffectivePattern before
sending to sidecar (no C# changes needed)
Settings UI:
- Add 'Agents' tab under Orchestration in the Settings panel
- Create WorkspaceAgentEditor component using ToolingEditorShell
- Show usage count (which patterns reference each agent)
Pattern editor integration:
- Add agent picker dropdown: 'New inline agent' or 'From library'
- Show linked badge (chain icon) on referenced agent graph nodes
- Show linked workspace agent banner in the inspector
- Add 'Save to Agent Library' action to promote inline agents
- Add 'Unlink' action to convert referenced agents back to inline
Tests:
- Add unit tests for resolution helpers (resolvePatternAgent,
resolvePatternAgents, findWorkspaceAgentUsages, normalize)
- Update existing tooling test for new agents field

- parse prompt model and argument-hint metadata and persist model on prompt invocations
- expand markdown-linked file context in scanned prompt and instruction bodies
- discover .claude/rules instructions and support Claude-style paths metadata
- discover customization roots up to the nearest parent repository and watch them for changes
- apply per-turn prompt model overrides before sidecar execution

When multiple MCP servers expose tools with the same name, the approval
pill showed an incorrect count (e.g. 150/300) even when everything was
approved. The numerator used a Set<string> to deduplicate by tool ID,
so shared tools were counted once, while the denominator counted each
group occurrence independently.
Extract countApprovedToolsInGroups() into shared/domain/tooling.ts and
switch to per-group counting that mirrors the totalItemCount formula.

- Relax branchSessionRecord validation to accept user or assistant roles
- Show "Branch from here" hover button on all conversation messages
- Contextual tooltip: "starting from this message" vs "continuing from this response"
- Add test for branching from assistant message
- Replace non-user rejection test with non-conversation rejection test

Add the backend contract and session-domain support for
'Branch from here':
- new branchSession IPC method and sessions:branch channel
- branchOrigin metadata on SessionRecord
- session branching helper that truncates the transcript at a
chosen user message and clears runtime state
- AryxAppService branching flow with scratchpad directory support
- persistence normalization and regression coverage

mergeDiscoveredToolingState now carries over probedTools from existing
servers when the config fingerprint is unchanged. The equality check in
syncProjectDiscoveredTooling also strips probedTools before comparing,
so runtime-only probe data never triggers a spurious state replacement.

When multiple MCP servers expose the same tool names (e.g., several
kusto-mcp instances), each server's group now shows its tools instead
of only the first server getting the tools and others showing 0/0.
Deduplicate the effectiveAutoApprovedCount to avoid double-counting
shared tools in the pill header.

When MCP server configs declare wildcard tools (empty tools array),
the Copilot SDK has no API to list individual tool names. Add direct
MCP protocol probing using @modelcontextprotocol/sdk to discover
available tools from each accepted server.
- Add McpToolProber service supporting stdio/SSE/HTTP transports
- Probe accepted MCP servers on project load, acceptance, and rescan
- Store probed tools on DiscoveredMcpServer and McpServerDefinition
- Use probed tools in listApprovalToolDefinitions when declared tools
are empty, so the approval pill shows individual tool toggles
- Remove unused isMcpServerApprovalKey helper
- Fix effectiveAutoApprovedCount Math.max workaround in ChatPane
- Add comprehensive tests for probed tool behavior
- Update ARCHITECTURE.md tooling integration section

MCP servers configured with empty tools arrays (wildcard) now appear in the
auto-approval pill with a server-level toggle. When toggled, a server-level
approval key (mcp_server:<name>) is added to autoApprovedToolNames. The
sidecar matches this key against PermissionRequestMcp.ServerName to auto-
approve all tools from that server without needing individual tool names.
- Add buildMcpServerApprovalKey/isMcpServerApprovalKey helpers
- Create approval groups for all MCP servers including empty-tools ones
- Add serverApprovalKey to ApprovalToolGroup for server-level toggles
- Update sidecar RequiresToolCallApproval to check server-level keys
- Include server-level keys in listApprovalToolNames for pruning safety
- Add tests for both shared domain and sidecar approval matching

Group MCP tools by server and LSP tools by profile in the approval popover
instead of showing a flat list. Each server/profile group gets a collapsible
header with a batch toggle to approve/unapprove all tools at once. Add a
search filter (visible when >10 tools) and partial-state indicators for
groups with mixed approval. Add groupApprovalToolsByProvider shared helper
with tests.

Add mode-aware graph mutation helpers for pattern topology so backend
code can add and remove agents without forcing a full graph rebuild.
Also preserve an existing pattern graph in savePattern instead of
re-syncing it from defaults, and cover the new behavior with shared
and main-process tests.

Add a builtin tool label registry mapping all ~30 official SDK tool IDs
to human-readable display names. Update listApprovalToolDefinitions to
resolve labels from the registry instead of showing raw tool IDs like
read_bash or fetch_copilot_cli_documentation. Expand the fallback
runtime tool catalog from 6 to 23 non-internal standard tools.

Generalize the scratchpad-only model/reasoning-effort selector to work
in any session whose pattern has exactly one agent. This enables model
switching above the chat input for project 1-on-1 chats, not just
scratchpads.
- Rename ScratchpadSessionConfig -> SessionModelConfig across domain,
contracts, IPC, preload, and renderer
- Replace isScratchpadProject guard with agents.length === 1 check in
EryxAppService.updateSessionModelConfig and ChatPane pills gate
- Apply session model config in buildEffectivePattern whenever present,
regardless of project type
- Seed sessionModelConfig on session creation for any single-agent
pattern

- load runtime tools dynamically from Copilot CLI capabilities via tools.list
- merge runtime tools with configured MCP and LSP tools in the approval catalog
- keep a fallback builtin runtime tool list when capabilities are unavailable
- move approval-tool pruning to the app service so dynamic tools are not dropped on load
- update approval UI and docs to use the corrected runtime-tool model

Add appearance theme support (dark/light/system) using CSS custom
property overrides. In light mode the Tailwind zinc scale is inverted
and semantic surface/border tokens are swapped, so all existing
utility classes pick up the new palette automatically.
- Add AppearanceTheme type and theme field to WorkspaceSettings
- Add setTheme IPC channel wiring (contracts, preload, handler, service)
- Add [data-theme='light'] CSS overrides for zinc scale, surface tokens,
scrollbar, and markdown prose colours
- Add Appearance section to SettingsPanel with radio-button theme picker
- Apply data-theme attribute on document root via useEffect in App.tsx,
with matchMedia listener for the system option

Audit confirmed that single, sequential, concurrent, and handoff are mapped to distinct workflow builders as intended. Group-chat was also using the correct round-robin manager, but the agents only had one-shot role prompts, so the reviewer could behave like a fresh assistant instead of refining the draft in progress. Add explicit runtime guidance for group-chat participants plus clearer built-in Writer/Reviewer instructions and regression coverage.
