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

Adds "Respond in the same language as the user's messages" to the
session title generator system prompt so titles match the conversation
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) ...

- 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

Fix Phosphor icon class on GnButton/GnIconButton usages. ...

gnexus-ui-kit's iconNode() does not prepend the base `ph` class
when the icon string starts with `ph-`; it only keeps the string
as-is. All icon props must include the base class explicitly:
`icon="ph ph-sidebar"` instead of `icon="ph-sidebar"`.

Updated 15 icon bindings across 9 components.

Auto-inject relevant memory facts into LLM context on every user turn. ...

Semantic search against the vector memory store runs in parallel with
context provider collection. Number of injected facts scales with
message length (1–3) to reduce noise on short queries. Guardrails:
min length gate, per-turn deduplication, and structured logging at
info level for observability.
