3-way action_tool_policy (off/ask/allow). In "ask", the chat stream stays
open and the tool loop awaits approval: emits event:tool_request, the UI
shows Approve/Deny, POST /chat/approve resumes the same stream. Declined
actions return a denied result; a timeout denies.

- Conversations bind to a project on creation; RAG scopes to the
conversation's project, not the global setting.
- Action tools (web_search/fetch_url/remember) are withheld unless
allow_action_tools is enabled (off by default). Settings toggle.

- Projects/workspaces: documents grouped into projects; chat RAG scopes to the
active project. Switcher in the Documents page.
- Agentic action tools: web_search, fetch_url, and remember (first write tool),
allowlist-gated per playbook.
- Local Whisper STT (faster-whisper, no torch): on-device dictation replacing
the browser Web Speech API. POST /stt + GET /stt/status; browser fallback.
- Vector index extended to conversation recall (message_vectors), with the
brute-force cosine scan kept as the fallback.

- Chunker: char overlap across boundaries + hard-split of oversized paragraphs.
- Retrieval knobs: rag_top_k / rag_min_score in settings + Settings UI.
- Vector index: sqlite-vec ANN over document embeddings, dual-written and
backfilled, with brute-force cosine as the guaranteed fallback.

- Upload endpoint (base64 JSON, no multipart dep): extracts text from
pdf/docx/txt/md via pypdf + python-docx, then runs the existing
chunk/embed pipeline. Documents page uploads files straight through.
- Citations: the chat stream emits an SSE `sources` event listing the
documents that fed the answer; the UI shows them as chips under the reply.
- Deps: pypdf, python-docx (both pure-Python, Windows-safe).

- install-windows.ps1: warn about a leftover profile-based ncp() that
would shadow ncp.cmd; the "press any key to close" footer now skips
the wait when stdin is redirected (was hanging indefinitely) and
exits cleanly instead of Stop-Process when it owns the window; pulls
nomic-embed-text alongside the chat/memory models.
- management/ncp.py: ncp start / start -b bring Ollama up automatically;
longer timeout + real error message on a slow model warm.
- synapse/nexus_config.py: DEFAULT_EMBED_MODEL, single source of truth
alongside DEFAULT_CHAT_MODEL/DEFAULT_MEMORY_MODEL.
- synapse/ollama_manager.py: is_available() cached instead of spawning a
process per /status poll; is_running() timeout dropped 2s -> 0.5s so a
healthy backend stops reading as dead; embed() reads the new default
instead of a hardcoded string; de-duplicated serve-env setup.
Ported via bin/publish.sh from NexusOS-jon.

The backend logged 200 OK for polls the client had already timed out on.
is_running() waited 2s for an Ollama that ships OFF (now 0.5s), is_available()
spawned 'ollama --version' every call and that command blocks ~5s when Ollama is
wedged (now cached), and both ran synchronously inside an async def, stalling the
event loop on every poll while the UI polls continuously (now to_thread).
Measured with Ollama's port blackholed: /status 5.89s -> 0.64s, concurrent GET /
stalled -> 0.06s. Poll timeout in nexus_window.py raised 2s -> 5s for margin.
