synapse/memory/service.py was deleted on 2026-08-25 when memory curation
moved in-process (curator.py) - there is no longer a second FastAPI app
to run on :8001. This CLI was evidently built against a pre-curator
baseline: `nexus serve` spawned `synapse.memory.service:app` (fails
with ModuleNotFoundError, logged only to memory.log where nobody would
see it), `nexus start memory`/`stop memory` had no handler at all
(silently fell through to show_help()), and doctor/status/monitor all
carried a "memory service" row that could never be anything but down.
Removed rather than repaired, since there's nothing to repair: the
service, its SERVICES entry, --memory-port/--no-memory, the -m/--memory
target everywhere it was offered (start/stop/logs/LEGACY_TARGETS), and
the memory_port/memory_url settings this PR had added. The `nexus
memory list|add|rm` data commands (nexus_api.py, hitting the backend's
own /memory REST endpoint) are untouched - unrelated, and still work.
A runaway preview script (sync infinite loop, or a re-render loop
outpacing the bootstrap's own coalescing) had nothing detecting it -
the frame just spun. The bootstrap now heartbeats every second, and the
parent tears the iframe down if it goes _WATCHDOG_MS silent, whatever
the cause.
_coerce_tool_calls recovers a tool call guessed from `content` for
models with no native tool_calls field. That guess is weaker evidence
than the API's own structured field - a model can land on JSON shaped
like a call while only meaning to describe one - so an action tool
recovered this way now always requires approval, even under the
"allow" policy that lets a native tool_calls field run unattended.
The CLI shipped from `management/`, which also holds desktop-only pieces (the
Tk control panel, the XFCE panel wiring, the shell wrappers). Packaging that
directory meant the wheel either dragged in tkinter or shipped a broken import.
Split it: `nexusos_cli/` is what the wheel ships and what `nexus`/`ncp`/
`nexusos` dispatch to, `management/` keeps the desktop half.
Alongside the move:
* hatch_build.py decides the interface/web/dist include at build time. dist/
is gitignored, so a static force-include aborts `pip install -e .` on a
fresh clone - before the reader reaches the `npm run build` step. Editable
installs now skip a missing dist; wheels and sdists hard-error naming the
command to run.
* synapse/proc_util.py gives frontend_manager and ncp process inspection and
termination without psutil, which became an optional extra when the wheel
landed. It routes around Windows having no signals, where os.kill(pid, 15)
is an unblockable TerminateProcess rather than a polite request.
* nexusos_cli/monitor.py adds `ncp monitor`, an ASCII dashboard with no curses
or rich dependency so it works in Termux, plain SSH and Windows Terminal.
Collector and renderer are separate so tests feed fixtures, no stack needed.
* tests/test_packaging_deps.py fails the gate when synapse or nexusos_cli
import a distribution pyproject does not declare, and when an optional
dependency is imported at module scope instead of lazily.
* bin/check.sh now builds the wheel, twine-checks it, and asserts the compiled
UI and seed playbooks are actually inside it. A wheel that builds but ships
no dist/ serves a blank page, which only shows up after release.
tests/test_nexus_api.py moves to tests/ with the module it covers.

Load Sucrase only when a JSX/TSX preview is opened, remove the hand-written transform, and leave subjective render evaluation to the reader while retaining structural fence validation.
Separate bind and client addresses, include Ollama's response body in HTTP failures, and strip inline <think> blocks from complete and streamed replies.
Repair vector rows left behind by older databases at store startup. Keep the existing single-statement delete path from main and avoid reintroducing the redundant batched helper.
Brings the public tree back in line with the development repo after several
weeks of drift caused by a stale publish include list.
New:
- In-app update path: GET /update/check compares the checkout against
origin/main and POST /update/apply runs `ncp upgrade` detached (pull,
rebuild, restart). The sidebar shows the version, checks on click, and
offers an "update available" pill.
- Projects: a project workspace groups chats and RAG documents, with
per-project instructions and document retrieval scoped to the active
project. Replaces the standalone Documents page.
- modules/: auto-discovered feature plugins (mail, network) with their
frontend counterparts and tests.
- Memory curation runs in-process (synapse/memory/curator.py) on the chat
model when a conversation goes idle. The separate memory service on :8001
is gone, along with the launcher lines that started it.
Also: the KDE theme, panel and Promethean terminal assets, the full test
suite, and VERSION 1.2.0.

- Clear button beside Export deletes every conversation currently listed. It
respects the search filter, so it doubles as "delete these matches"; the
confirm text names which of the two is about to happen. Starts a fresh
conversation id if the active one was among those deleted.
- The separate Start/Stop AI button is gone. The status dot was already
colour-coding the same state and sitting right above it, so clicking it now
toggles Ollama and the tooltip carries the phase text ("loading model…"),
which is where the eye already is during the wait.
- Active nav/conversation items are marked with a blue left border and
weighted text instead of a filled background, and the sidebar is wider so
conversation titles stop truncating.

network-manager-gnome autostarts its own systray icon from /etc/xdg/autostart,
which duplicates the network genmon (plugin-13) already in the panel. Override
it with a Hidden=true user-level .desktop, the same way blueman-applet and
nm-tray are already handled, and copy it into place from the panel installer.

Neither the Plymouth theme nor the login/lock theming was ever installed by a
restore, so a rebuilt box came up with stock distro branding.
bin/boot-branding.sh installs all three, and the desktop stage of
restore-linux.sh calls it. Each block self-skips when its greeter is absent or
already current, so it is cheap to re-run and works whether the box boots
lightdm or SDDM:
- Plymouth: a real copy under /usr/share/plymouth/themes, not a symlink into
the user home. The stock initramfs hook copies the theme path verbatim, so a
symlink into an unmounted home dangles at early boot and Plymouth drops to
text mode -- which is what assets/boot/initramfs-hook-my-custom-logo existed
to work around. With a real copy that hook is unnecessary.
- SDDM: the NexusOS-QML theme, selected via /etc/sddm.conf.d.
- slick-greeter: cannot lay out a custom login screen, so the logo and wordmark
are baked into assets/themes/greeter/greeter-background.svg and its own
centered login box lands underneath.
Main.qml now loads background.png instead of background.svg. QtSvg implements
SVG Tiny 1.2, which has no <pattern>, so the brushed-metal and machine-line
textures silently dropped out at runtime. librsvg renders them, so the SVG is
rasterized at 1920x1200 and committed alongside it; the regeneration command is
in the comment above the source: line.

Rewritten from a coding-rules-only playbook into the full mode: minimal
solutions AND compressed speech, triggered per conversation by tag.
Two rules lead the prompt because a small local model drops whatever is buried
in the middle. Rule 1: anything destructive gets a full-sentence warning BEFORE
the command, naming what is lost and what to back up - brevity never applies
there. Rule 2: an abstraction asked for with a single use gets a one-line
"not needed" and the small version instead. Rule 1 is repeated at the very end,
which is what made it hold in testing.
Tags carry the trigger words. A reference playbook is injected only when one of
its tag words appears in the message (_route_playbooks), so a playbook with no
matching tag never routes in at all.
Known limits, measured against llama3.1:8b: as a reference playbook only the
voice holds reliably. The build ladder and the warning-before-command ordering
need the playbook promoted to first position, because the chat endpoint appends
memory facts, conversation snippets and documents AFTER the reference block - a
reference playbook cannot own the end of the prompt, so a rule needing recency
weighting cannot get it.

Ported from downstream development. Four independent defects.
1. The memory dump was unrestorable. iterdump() serializes sqlite_vec virtual
tables as a raw INSERT INTO sqlite_master(...) followed by inserts into a
table the replaying connection cannot see, so replaying memory.db.sql died
on "no such table: vec_messages" and left ZERO tables behind. dump_db() now
loads the vec0 extension and filters the derived vec tables out of the
iterdump stream, matched on each statement's target table rather than as a
substring - a chat message whose text mentions vec_messages is an
INSERT INTO "messages" and has to survive.
compare() reported an unreadable dump as "diverged", which read like a real
verdict and made both guards refuse backup AND restore, locking the machine
out of syncing in either direction. Unreadable is now its own verdict.
_extra() compared updated_at against a "" default, but the column is REAL,
so the comparison raises TypeError on the first conversation the other side
lacks - exactly the case it counts. It tests membership first now. The
direction test declared updated_at TEXT, which is why this survived: the
test compared str to str while the field compared str to float.
2. The memory curator invented facts. It attributed the ASSISTANT's words to
the user, wrote absence claims read off the existing-memory block, and added
judgements ("favorite") the user never used. The prompt now scopes the USER
line as the only source, and two deterministic guards drop absence claims
and facts whose distinctive tokens appear nowhere in the user's message -
prompt wording alone did not hold on a 7B curator.
3. _best_vulkan_device scored Mesa's llvmpipe above an integrated GPU, pinning
Ollama to a software rasterizer advertising 31 GiB of "VRAM" - CPU inference
with Vulkan overhead on top. Software rasterizers are dropped.
4. Models.jsx compared catalog names to installed names literally, but Ollama
resolves a bare name to ":latest", so an untagged entry (nomic-embed-text)
read as missing forever and the Required gate never opened. Chatbot.jsx
fetched the model list once on mount although App keeps the page mounted
behind display:none, so a newly pulled model never appeared in the picker
until a full browser reload.

DoS/quota guardrails for the unauthenticated local APIs:
* Body-size middleware rejects oversized requests (Content-Length) before they
are buffered/base64-decoded (NEXUS_MAX_REQUEST_MB, default 32).
* Document upload enforces a decoded-byte cap (NEXUS_MAX_UPLOAD_MB, default 20)
and a PDF page-count cap (NEXUS_MAX_PDF_PAGES, default 500) as backstops for
chunked bodies and pathological files.
* A counter-based in-flight limiter bounds concurrent chats and document
ingests (NEXUS_MAX_CONCURRENT_CHATS/UPLOADS), returning 429 when saturated;
the chat slot is held for the whole SSE stream and released on completion or
client disconnect.
* /models/pull gains an opt-in allowlist (NEXUS_MODEL_ALLOWLIST); empty by
default so behaviour is unchanged, otherwise a bare repo name permits all its
tags.

Two tool/agent-layer hardening changes:
* fetch_url now resolves the target host and refuses to connect if any
resolved address is loopback, private (RFC1918/ULA), link-local (incl. the
169.254.169.254 cloud-metadata endpoint), multicast, reserved, or
unspecified. IPv4-mapped IPv6 is unwrapped first, and the guard re-runs on
every redirect hop so a public URL cannot 302 its way to an internal target.
* /chat/approve now requires a single-use token minted when the stream pauses
for approval and delivered only in that stream's tool_request event, compared
in constant time. Previously the pending approval was keyed solely on a
client-supplied conversation_id, so anyone who could enumerate a
conversation_id could approve another client's pending action.
The frontend threads the token from the tool_request event into the approve
call.

The Synapse backend and memory service bound 0.0.0.0 with wildcard CORS and no
auth, exposing the full unauthenticated admin/data API to the LAN. Default the
uvicorn bind to 127.0.0.1 (NEXUS_BIND_HOST override), scope CORS to known local
origins instead of "*", and add TrustedHostMiddleware to reject foreign Host
headers (which defeats DNS-rebinding, something same-origin CORS cannot stop).
NEXUS_ALLOWED_HOSTS / NEXUS_ALLOWED_ORIGINS allow opt-in LAN exposure, intended
to be paired with real authentication.

New Modules entry in Flagship features + Architecture describes the
modules/ plugin auto-discovery. Chat/vision/voice, action tools,
Layout, and Configuration reworded from prose/tables into bullets for
scannability.
Bugs go through this repo's Issues tab with an ncp doctor ask; feature
requests stay pointed at NexusOS-requests so the bug tracker doesn't
mix with the planning backlog.
core.fileMode=false (repo-local or a machine-wide /etc/gitconfig) can
silently drop the +x bit on every tracked script during checkout, which
then surfaces later as a confusing "Permission denied" on whatever
script happens to run next rather than as an obvious failure up front.
ensure_exec_bits() re-applies +x from `git ls-files -s` (mode 100755)
right after every pull, so a restore is self-healing regardless of cause.

requirements-amd.txt/requirements-nvidia.txt were pulling a multi-GB
torch wheel by default even though nothing in synapse/ imports torch,
transformers, accelerate, bitsandbytes, or PySide6 - dead weight that
made the pip batch fragile (one failed download could take unrelated
base deps down with it on a slow connection). Split the unused ML/GUI
stack out of requirements-base.txt into a new opt-in requirements-ml.txt,
and dropped the torch lines from the AMD/NVIDIA overlays and generator.
Also: recreate the venv if it exists but pip is missing, instead of
silently reusing a half-built one (ensurepip can fail during venv
creation and leave an interpreter with no pip).

Newer distros drop the python3-venv transitional package once it no longer
resolves to a real pythonX.Y-venv candidate, which crashed sync.py's venv
creation with a raw traceback. Prep now resolves the exact versioned
package via apt-cache, and skips xfce4-genmon-plugin/plank/blueman on
boxes with no xfconf-query so a non-XFCE box doesn't get noisy "unable to
locate package" failures for a panel it'll never run. venv_python() also
fails with an actionable message instead of an uncaught CalledProcessError.

Ported from the private repo (bin/publish.sh's README-only path): adds a
Flagship features section, reorders Quick start (Linux first), splits out

replaces the stale in-README Roadmap with a pointer to NexusOS-requests.

Ported from the private repo via bin/publish.sh, plus a manual catch-up
on files that had drifted out of sync before today:
- launch_nexus.ps1: health-check based restart decisions instead of a
bare port-listen check (a wedged leftover process squatting a port
used to look "already running" and block the real service from
starting), a script-path quoting fix for Start-Process, hidden
console via a wscript.exe wrapper (bin/launch_nexus_hidden.vbs), and
a taskbar/window icon for the native app window.
- Sidebar: slim icon+text nav rows instead of bulky bordered buttons,
tighter spacing throughout.
- Settings: full-width layout, a Vite dev-server Start/Stop toggle
(synapse/frontend_manager.py + /frontend/* endpoints), and the
Linux-only Icon Branding section now gated on the new /status
`platform` field instead of always rendering.
- Chatbot: a Think toggle next to the model picker, so extended
thinking can be flipped without leaving the chat page.
- management/ncp.py: faster start/stop polling (0.25s steps instead of
1s), Vite no longer blocks `ncp start` on Linux and is skipped
outright on Windows.
Note: the private repo also has a Mail (IMAP/SMTP) feature; it's
intentionally not included here, so the Mail-only pieces of main.py,
App.jsx, and requirements-windows.txt were left out of this port.
Models page redesign: tabs (Required/Recommended/Installed) with a
multi-column card grid, required models (memory curator + embeddings)
surfaced first and gating the rest until both are installed. Adds a
qwen2.5:14b tier to the hardware-fit catalog for high-VRAM machines.
Installer and restore messaging updated to match. Also declares pytest
in requirements-base.txt so bin/check.sh's test suite is reproducible
on a fresh venv.

Models.jsx clipped the whole card with overflow:hidden while only the
"Available Models" section (never visible when the hardware-recommended
list alone filled the card) had its own scroll — the installed-models
list was unreachable with no scrollbar. The whole card now scrolls as
one region instead.
install-windows.ps1's original (non-elevated) window printed "Requesting
administrator privileges..." and exited immediately, so all real
progress and the "installed!" banner only ever appeared in the separate
elevated window — making the original window look like it silently
quit. It now waits (-Wait -PassThru) and reports success/failure itself.

3-way action_tool_policy (off/ask/allow). In "ask", the chat stream stays

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.

- Chunker: char overlap across boundaries + hard-split of oversized paragraphs.
- Retrieval knobs: rag_top_k / rag_min_score in settings + Settings UI.

- 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).
