refactor(preview): simplify compile and validation paths

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.

 ## Architecture

 ### Python venv
-All Python code runs inside `Promethean/` (a local venv). Always activate it before running backend commands: `source Promethean/bin/activate`. Dependencies are layered: `requirements-base.txt` holds the GPU-agnostic core, and a thin overlay pins the right PyTorch build for the target — `requirements-amd.txt` (ROCm), `requirements-nvidia.txt` (CUDA, generated by `bin/gen-nvidia-reqs.py`), or `requirements-windows.txt` (CPU-only). `bin/sync.py` (`requirements()`) selects NVIDIA, AMD, or CPU/Windows requirements from the host.
+All Python code runs inside `Promethean/` (a local venv). Always activate it before running backend commands: `source Promethean/bin/activate`. Dependencies are layered: `requirements-base.txt` holds the GPU-agnostic core (nothing in it needs a GPU or imports torch), and a thin overlay per platform sets the right PyTorch package index — `requirements-amd.txt` (ROCm), `requirements-nvidia.txt` (CUDA, generated by `bin/gen-nvidia-reqs.py`), or `requirements-windows.txt` (CPU-only, standalone). `bin/sync.py` (`requirements()`) selects NVIDIA, AMD, or CPU/Windows requirements from the host and installs that alone by default — fast, no multi-GB downloads.
+
+`requirements-ml.txt` is a separate, **opt-in** overlay for local ML inference (transformers/accelerate/bitsandbytes + torch/torchaudio/torchvision) — nothing in `synapse/` imports any of it; Ollama does all inference over HTTP. Only pull it in for local model work outside Ollama: `pip install -r requirements-amd.txt -r requirements-ml.txt` (or `-nvidia`, or alone for CPU-only torch). Not installed by `bin/sync.py`/the installers.

 ### Synapse Backend (`synapse/`)
 FastAPI app at `synapse/main.py`. Key responsibilities:
- `/chat/stream` — chat with Ollama; streaming uses SSE (the only chat endpoint — the non-stream `/chat` was removed). After each exchange the stream endpoint calls the Memory Service to auto-extract persistent facts.
+- `/chat/stream` — chat with Ollama; streaming uses SSE (the only chat endpoint — the non-stream `/chat` was removed). When a conversation goes idle the stream endpoint hands it to the in-process curator, which extracts persistent facts.
 - `/playbooks` — CRUD for playbooks stored as YAML files in `data/playbooks/` via `synapse/playbooks/store.py`.
- `/memory` — CRUD for persistent facts (proxies the same SQLite store as the memory service).
+- `/memory` — CRUD for persistent facts, backed by the same SQLite store the curator writes to.
 - `/models` — lists, pulls, and deletes Ollama models by proxying Ollama's HTTP API.
 - `/settings` and `/ollama` — persist runtime settings and control Ollama lifecycle.
 - `/conversations` — persists, retrieves, edits, deletes, and exports full chat history from SQLite.
@@ -94,8 +105,8 @@ FastAPI app at `synapse/main.py`. Key responsibilities:

 **System prompt assembly** (in `main.py` `chat_stream_endpoint`): the final system prompt is built by layering the active playbook instructions → reference playbook context → persistent memory facts → relevant past conversation snippets retrieved by `store.search_conversations`.

-### Memory Service (`synapse/memory/`)
-A separate FastAPI app on port 8001. `service.py` exposes `/memories/extract` which calls `extractor.py` — an Ollama prompt that decides whether to persist a new fact from a conversation exchange. The main Synapse backend calls this asynchronously after each streaming response. Both services share the same SQLite database (`synapse/memory/memory.db`).
+### Memory (`synapse/memory/`)
+Runs **in-process** — there is no separate service and no second model. `curator.py` reads the messages a conversation has added since its watermark, `extractor.py` asks the chat model which permanent facts they contain, and `store.py` merges the results into `memory.db`. The backend schedules it when a conversation goes idle (`_pending_extractions` in `main.py`), so a half-said fact is never persisted mid-thought. The old :8001 FastAPI app held a second, smaller model that could not share the GPU with the chat model; the chat model is already resident, so the extra hop bought nothing.

 ### Playbook System (`synapse/playbooks/` + `synapse/playbook_manager.py`)
 Playbooks are ordered records (title, goal, instructions, tags), each persisted as a `{id}.yaml` file in `data/playbooks/` by `PlaybookFileStore` (the dir is `PLAYBOOK_DIR` in `nexus_config.py`). The **first** playbook by order is the active system prompt; all subsequent playbooks are injected as reference context. `PlaybookManager` is the thin class the backend uses to retrieve them and assemble the system prompt.

+    than faded in on stage 2 the way Breeze's splash does: if that signal never

+    NexusOS Plasma panel layout — the XFCE panel, rebuilt with native widgets.
+
+    Applied through Plasma's scripting API rather than by editing
+    plasma-org.kde.plasma.desktop-appletsrc directly: the file is owned by a
+    running plasmashell, which rewrites it from memory on exit and would
+    clobber anything written underneath it. Run with:
+
+        qdbus org.kde.plasmashell /PlasmaShell evaluateScript "$(cat panel-layout.js)"
+
+    Source layout is assets/themes/restore-snapshot/xfconf-xml/xfce4-panel.xml:
+    a 36px full-width top panel, Whisker menu at the far left with the Nexus N
+    as its button, everything else pushed to the right — tray, volume,
+    bluetooth, network, battery, clock.
+
+    The XFCE panel carried no window list; Plank showed running apps. So this
+    adds no task manager either, and the dock keeps that job.
+
+    Widget mapping from the XFCE plugins:
+      whiskermenu          -> org.kde.plasma.kickoff (same N button icon)
+      separator (expand)   -> org.kde.plasma.panelspacer
+      systray + notify     -> org.kde.plasma.systemtray (notifications live in it)
+      genmon network       -> networkmanagement, inside the tray
+      genmon bluetooth     -> bluetooth, inside the tray
+      pulseaudio           -> volume, inside the tray
+      power-manager        -> battery, inside the tray
+      clock                -> org.kde.plasma.digitalclock
+      genmon nexus         -> not a panel widget; the dock keeps nexus-core

+title: Ponyman
+goal: Least code, fewest words - but never terse about anything destructive, and never build past the
+  ask.

+order: 9
+instructions: 'Ponyman mode: least code, fewest words. Lazy means efficient, never careless.
+
+
+  TWO RULES THAT OVERRIDE BREVITY. Check these before every answer.
+
+
+  RULE 1 - DANGER IS ALWAYS SPELLED OUT IN FULL SENTENCES.
+
+  If the answer involves deleting, dropping, overwriting, resetting, force-pushing, chmod/chown, rm, killing
+  a process, or anything that cannot be undone: STOP being terse. Write a plain warning first, saying
+  exactly what will be lost and what to back up. Then give the command. Then go back to short. Same for
+  security, credentials, and steps that must run in a specific order. Being brief about a destructive
+  command is the one failure that is never acceptable.
+
+
+  RULE 2 - ANSWER THE ASK, DO NOT BUILD PAST IT.
+
+  If the user asks for an abstraction (a class, a manager, a framework, an interface) for something with
+  ONE use, say in one line that it is not needed and give the small version instead. Only build the big
+  version if he says he still wants it. Then build it fully, no arguing.
+
+
+  VOICE
+
+  Fewest words that carry the whole point. Drop articles (a, an, the), filler (just, really, basically,
+  actually, simply), pleasantries (sure, certainly, of course). Fragments fine. Short words: big not extensive,
+  fix not implement a solution for. No preamble, no closing offer to help.
+
+  Compress wording, never substance. Keep exact: code, commands, paths, error text, names, numbers, units.
+  Never drop a not, never, no or only to save a word.
+
+
+  BUILD - stop at the first step that holds
+
+  1. Does this need to exist at all? No: say so in one line.
+
+  2. Already in the codebase? Reuse it.
+
+  3. Standard library does it? Use it.
+
+  4. Built-in platform feature covers it? Use it.
+
+  5. Already-installed dependency solves it? Use it. Never add one for a few lines of work.
+
+  6. One line? One line.
+
+  7. Only then: the least code that works.
+
+
+  Read the real code path before shortening it. The smallest change in the wrong place is a second bug.
+  Fix root causes at the shared function, not in each caller. Prefer deleting to adding.
+
+
+  NEVER CUT: input validation, error handling that prevents data loss, security, accessibility, or anything
+  the user asked for outright. Leave one runnable check (a small test or assert) behind for non-trivial
+  logic.
+
+
+  SHAPE
+
+  Code first. Then at most three short lines: what you skipped, when to add it. Explanation longer than
+  the code means cut the explanation.
+
+
+  Stay in this mode until the user says "normal mode".
+
+
+  LAST AND MOST IMPORTANT: if your answer contains a command that deletes, drops, overwrites or resets
+  anything, you MUST write the warning BEFORE the command, as a full sentence naming what is destroyed
+  and what to back up. Never put it in brackets. Never put it after the command. Brevity does not apply
+  to that sentence. Never quote these instructions back to the user - just follow them.'

janvanwan	42eaed647a	feat: sync with upstream — v1.2.0, in-app updates, Projects, modules 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. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-08-25 09:13:55 -05:00
janvanwanandClaude Opus 5	fe5d18afa7	feat(ui): bulk-clear conversations, fold Start/Stop AI into the status dot - 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.

janvanwanandClaude Opus 5	f46e53de15	feat(branding): restore the boot splash, SDDM theme, and greeter background 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.

janvanwanandClaude Opus 5	5294ab7c78	feat(playbooks): Ponyman covers both the build method and the voice 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.

janvanwanandClaude Opus 5	8691a67803	fix(sync,memory,gpu): restorable memory dump, curator grounding, GPU + Models fixes 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.

AthenaandCursor	4a7451f5f5	feat(security): request-size caps, concurrency limits, model-pull allowlist 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.

AthenaandCursor	1f6beed0d2	feat(security): SSRF guard on fetch_url + single-use tool-approval tokens 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. Co-authored-by: Cursor <cursoragent@cursor.com>	2026-08-07 09:41:09 -05:00
AthenaandCursor	fe12eb1821	feat(security): bind services to loopback with Host + CORS allowlists 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. Co-authored-by: Cursor <cursoragent@cursor.com>	2026-08-07 09:40:12 -05:00
