Fix profile icon class in WelcomeScreen — prepend 'ph' prefix ...

GnAvatar's :icon prop expects the full Phosphor class (e.g. 'ph ph-briefcase'),
not just the icon name. profileIcon() now returns 'ph ${cls}'.

Fix GnAvatar usage: use props (src/icon/initials) instead of default slot ...

GnAvatar render function ignores default slot content; it only reads
src, icon, and initials props. Fixes broken user avatar image display.

Add profile_id support to list_tools ...

ListToolsTool now accepts an optional `profile_id` parameter. When
provided, it returns only the tools enabled for that specific profile
(enabled_tools + user tools + resolved MCP tools). This helps the agent
preview what a profile can do before switching.

- Updated ListToolsTool.execute() with profile-aware filtering
- Patched _profile_registry in build_default_registries
- Patched _mcp_manager in main.py startup loop

Fix gnexus-book MCP instructions and add old-format fallback in tool executor ...

- Updated mcp_servers.json gnexus-book instructions to use mcp:gnexus-book:
  prefix instead of the old mcp_gnexus-book_ format.
- Added fallback in tool_executor.py for old underscore format
  (mcp_server_tool → mcp:server:tool) so transitional models still work.
- Added unit test for the old-format fallback.

Set browser tab title to active session name or id ...

In App.vue: added computed `documentTitle` and a `watch` that updates
`document.title` whenever the active session changes or its name is
updated. Falls back to session id prefix (8 chars) when unnamed.

Generate session titles in the user's language ...

Adds "Respond in the same language as the user's messages" to the

language instead of defaulting to English.

Fix profile MCP server groups to use group names instead of tool names ...

Profile configs were listing individual tool names (web_view, http_request)
in mcp_servers.navi-web instead of group names (browse, request). This caused
resolve_group() to return empty results, so MCP tools never appeared in the
profile's resolved tool list.

Also fixes modeler_3d stale tool references in system_prompt.txt.

Fix agent.py _tool_list to use colon-delimited MCP names ...

The main registry and API routes were migrated, but Agent._tool_list
still built names with the old underscore format. This meant MCP tools
were silently dropped from the tool list passed to the LLM, causing
"tool not found" when the model correctly called mcp:server:tool names.

Also updates stale docstring in McpTools.

Rename MCP tools to mcp:server:tool format and restore human-readable names ...

- Core naming: mcp_server_tool → mcp:server:tool (colon-delimited)
- navi-web tools: search/view/request → web_search/web_view/http_request
- navi-3d tools: compile_scad/render_stl/lint_scad (unchanged names)
- Updated all profile configs, system prompts, docs, manuals, tests
- Added new lint_scad.md manual
- Fixed modeler_3d prompt stale references (scad_lint, model_3d, render_3d)
- All 240 tests pass

Clean up remaining web_search / web_view / http_request references ...

- Deleted stale source files: navi/tools/web_search.py, web_view.py,
  http_request.py (no longer imported or registered).
- Updated system_prompt.txt in all profiles (secretary, server_admin,
  discuss, modeler_3d subagent) to reference mcp_navi-web_* tool names.
- Updated key_tools in developer, secretary, server_admin config.json.
- Updated docs (tools.md, profiles.md, api.md) to reflect MCP migration.

Tests: 240 passed.

Rename navi-web MCP tools and compact search output ...

- web_search → search, web_view → view, http_request → request
  This removes the redundant 'web' prefix from tool names in the
  navi-web MCP server, making them cleaner: mcp_navi-web_search etc.

- Compact search output: output string now contains only
  [Source] + [N] Title — URL, without duplicating the body snippet.
  Full results with body/description remain in metadata for
  programmatic use.

- Updated mcp_servers.json groups and all profile configs.

Tests: 240 passed.

Migrate web tools (web_search, web_view, http_request) to navi-web MCP server ...

New MCP server: mcp-servers/navi-web/
- app/search.py    — SearXNG primary, DDG fallback, Brave tertiary
- app/browse.py    — Playwright headless browser page extraction
- app/request.py   — httpx raw HTTP requests
- app/mcp_server.py — FastMCP entry point with stdio transport
- pyproject.toml   — deps: mcp, httpx, ddgs, playwright, pydantic

Changes:
- Added "navi-web" block to mcp_servers.json (stdio transport)
- Removed web_search, web_view, http_request from built-in registry
- Removed them from navi/tools/__init__.py
- Removed them from enabled_tools / subagent_tools in all profiles
- Added "navi-web": ["search", "browse", "request"] to mcp_servers
  in all profiles (developer, secretary, server_admin, tool_developer,
  modeler_3d, discuss)

Tests: 240 passed.

Fix navi-3d MCP tool coroutine serialization error ...

All three tool handlers (compile_scad, render_stl, lint_scad) were
calling async core functions without await from synchronous def bodies.
This caused FastMCP to receive a coroutine object instead of a dict,
which then failed JSON serialization with:
  Object of type coroutine is not JSON serializable

Fix: convert tool handlers to async def and await the underlying
compile_scad / render_stl / lint_scad calls before passing to _json().

Tested via stdio_client — lint_scad now returns clean JSON result.

Fix navi-3d MCP tool name mismatch ...

The MCP server registered tools with `_tool` suffix (e.g. lint_scad_tool)
but mcp_servers.json groups listed bare names (lint_scad). This caused
_tool_list() to look for mcp_navi-3d_lint_scad which never existed in the
registry — the actual registered tool was mcp_navi-3d_lint_scad_tool.

Fix: explicitly set name= on @mcp.tool() decorators so MCP tool names
match the group whitelist in mcp_servers.json.

Set navi-3d MCP server to stdio transport via env var ...

Adds NAVI_3D_MCP_TRANSPORT=stdio to mcp_servers.json so the server
starts in stdio mode instead of defaulting to SSE (uvicorn).
Prevents uvicorn access logs from leaking into stdout and breaking
JSON-RPC message parsing.

Fix navi-3d stdio MCP cwd to avoid conflicting app.py import ...

The navi-1 root contains an old app.py (Flask). Without cwd, python -m
app.mcp_server imported that file instead of the navi-3d app package.

Switch navi-3d MCP to stdio transport (local, no web server) ...

- transport: stdio instead of sse
- command: direct venv python path
- env: SESSION_FILES_DIR pointing to navi-1 session_files

SSE remains available via NAVI_3D_MCP_TRANSPORT=sse for dev/debug.

Migrate 3D modeling tools to standalone MCP server navi-3d ...

Phase 0 — Fix MCP error propagation:
- McpClient.call_tool now returns (output, is_error) tuple
- McpTool.execute sets success=False when MCP reports isError=True
- Fixes silent failures where MCP errors looked like success

Phase 1 — Create mcp-server-navi-3d:
- New standalone MCP server in mcp-servers/navi-3d/
- Tools: compile_scad, render_stl, lint_scad
- Session-scoped path resolution via SESSION_FILES_DIR env
- Anti-escape validation for security
- Includes tests/unit/test_scad_analyze.py

Phase 2 — Remove from Navi core:
- Deleted navi/tools/{model_3d,render_3d,scad_lint}.py
- Removed from registry.py builtins and navi/tools/__init__.py
- Updated pyproject.toml testpaths to exclude mcp-servers/

Phase 3 — Wire into Navi config:
- Added navi-3d block to mcp_servers.json (SSE on :8002)
- Updated modeler_3d profile: mcp_servers + updated system_prompt
- All old tool names replaced with mcp_navi-3d_* equivalents
