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.
Reconciles 17 commits of this session's work (self-alteration tools,
vendored Curry, slash-command dispatch, Windows toolchain/gate fixes)
against origin/main's v1.2.0 sync (Projects/RAG scoping, a new modules/
system for mail and network, in-app updates, the standalone memory
microservice folded into an in-process curator, KDE desktop theme
overhaul). Nine real conflicts, each resolved by hand after reading both
sides' actual diffs rather than picking one side wholesale:
- synapse/tools.py, tests/test_tools.py: origin/main's diff here was
small and clean (read_file/list_files, two new tests) despite git's
diff3 flagging the whole file as one conflict blob -- reset to this
branch's version and hand-spliced their addition in at the same
points they used, rather than trying to reconcile a false 800-line
conflict. Found and fixed a real bug while verifying: _list_files
returned backslash-separated paths on Windows, which don't match the
forward-slash glob patterns the tool's own schema documents.
- synapse/main.py: kept this branch's cue-based standing advertisement
of render_preview/run_snippet (independent of any playbook granting
them) AND adopted origin/main's fix for routed reference playbooks
not bringing their own tools along -- dropping either would have been
a real regression, not just a style difference. Also: the standalone
memory service (port 8001) is gone upstream, so its dead CORS/kill-
target entries were removed; NEXUS_BACKEND_PORT parameterization and
the manage_ollama-conditional kill logic (this branch's remote-Ollama
support) were kept over origin/main's hardcoded equivalents.
- synapse/memory/store.py: kept this branch's _delete_message_vectors
helper (already reused elsewhere, batches to stay under SQLite's
variable limit) over origin/main's inline duplicate of the same fix.
- synapse/nexus_config.py, nexusos_cli/ncp.py: dropped the now-dead
memory-service port/service entries; kept NEXUS_BACKEND_PORT env
override and the manage_ollama-conditional kill-target list.
- CLAUDE.md, README.md: merged both sides' additions, no real conflict.
Found and fixed three more issues while independently verifying the
merged tree, none of them mine or origin/main's alone -- only visible
once both sides actually ran together:
- modules/ (the new mail+network package) was never added to
pyproject.toml's wheel `packages` list OR the sdist's `include`
allowlist, so `from modules.registry import ROUTERS` in main.py would
ImportError on any wheel install. Fixed both; bin/check.sh's
packaging gate now asserts modules/ actually ships. tests/
test_packaging_deps.py's FIRST_PARTY/SHIPPED_PACKAGES sets were
updated to recognize the new package.
- tests/test_mail_creds.py's 0600-mode assertions are POSIX-only --
NTFS has no equivalent permission bits, so os.open(path, 0o600) on
Windows just creates a normal file and stat.S_IMODE reports 0o666
regardless. Made the assertions platform-aware rather than skip real
coverage (the temp-file-cleanup and password round-trip checks in the
same test still run on Windows) or paper over a genuine OS
limitation with a fake pass.
- tests/test_kde_theme.py used bare Path.read_text() in fifteen places;
Windows' default locale encoding (cp1252, not UTF-8) can't decode a
real UTF-8 byte in the QML it reads, and did fail on one of the
fifteen. Fixed all fifteen, not just the one that happened to trip
today, since the other fourteen were equally fragile.
Verified: full bin/check.sh reports OK end-to-end on this Windows
checkout -- pytest (tests + management): 295 passed, 0 failed, 9
skipped; eslint clean; frontend node:test 57/57; PowerShell/shell
parse clean; wheel + sdist pass twine check and now correctly carry
modules/ (60 files, up from 52 pre-merge). synapse.main:app builds
with 74 routes (up from 54 pre-merge, matching the new Projects/mail/
network endpoints).
code_run.py: shutil.which() finding a compiler executable on PATH doesn't
mean it's a usable toolchain on Windows -- rustc's MSVC target also needs
Microsoft's linker, and an MSYS2 gcc/clang driver can remain resolvable after
one of its runtime DLLs has broken. Both cases silently turned every C/C++/
Rust snippet into a compile error while the capability check said "ready".
_compiled_tool() now actually compiles+links a trivial known-good program
per candidate (Windows only; POSIX keeps the cheap which(1) check since
release hosts install compiler packages atomically) and caches the result.
Also fixes the run/compile child environment: HOME/TMPDIR don't control
Windows' real temp/profile resolution (expanduser() reaches the actual user
profile, GetTempPath() falls back to the Windows directory), letting a
snippet escape the scratch directory or fail outright. _child_env() now also
sets TEMP/TMP/USERPROFILE on Windows.
tests/conftest.py (new): isolates curry_store's SQLite singleton into a
per-run temp directory via NEXUS_CURRY_DB before any test module imports
synapse, and cleans it up at session end -- the release gate no longer
writes test constants into the checkout's live data/curry.db. .gitignore
picks up /data/curry.db for whatever still lands there locally.
bin/check.sh: falls back to Promethean/Scripts/python.exe when
Promethean/bin/python doesn't exist, so the gate actually runs on a Windows
venv instead of immediately exiting "no Promethean venv".
Verified independently: 254 passed, 0 failed, 8 skipped (tests + management)
-- the 12 C/C++/Rust toolchain failures present all session are gone. Full
bin/check.sh run end-to-end on this Windows checkout: pytest, eslint,
frontend node:test (57/57), PowerShell/shell parse, and the wheel/sdist
packaging + twine + content checks all report OK.

Adds synapse/slash_commands.py: a chat message that's nothing but
/tool_name(arg=val, arg=val) dispatches straight through tools.dispatch(),
skipping model selection, RAG/playbook context assembly, and the ask-policy
approval round-trip entirely. A human typing this IS the approval - there's
no one else to ask - so it's a deliberate, reviewed bypass of the approval
step specifically, not of anything a tool validates internally (path
boundaries, size caps, Curry's own sandbox checks all still run). Argument
values parse via ast.literal_eval only: strings/numbers/bools/None/literal
containers, no names, no calls, no attribute access - a malformed or
hostile-looking argument fails to parse rather than executing anything.
Wired into chat_stream_endpoint (main.py) as an early short-circuit, before
any of the RAG/model-selection work that a slash-command doesn't need. Web
needed no changes (it already forwards raw text unchanged); the TUI
previously swallowed every leading "/" locally and never reached the backend
with it, so tui_app.py's _handle_slash now falls through to _start_chat for
anything shaped like a tool call while still handling its own local
meta-commands (/help, /model, /new, ...) exactly as before.
Also finally wires Curry in as ten real tools (curry_declare_constant,
curry_get_constant/_latest, curry_list_constants, curry_retire_constant,
curry_declare_function, curry_get_function, curry_list_functions,
curry_call_function, curry_retire_function) - deferred from the vendoring
pass. The five write/execute ones are ACTION tools in the same
always-ask-regardless-of-global-policy floor as edit_source
(ALWAYS_ASK_ACTION_TOOLS, generalized in tools.py from the old
self_edit-only ALWAYS_ASK_TOOLS so future tool families share one place to
register into). curry_call_function is gated as an action for the same
reason run_snippet is: it executes code, even sandboxed.
Fixed a real bug surfaced while wiring this up: curry_db is a long-lived
singleton holding one sqlite3 connection (unlike NexusOS's own memory store,
which opens/closes a fresh connection per call specifically to dodge this),
and sqlite3 forbids using a connection from a different thread than created
it. That's a non-issue in production (uvicorn's single event-loop thread),
but Starlette's TestClient runs the ASGI app through an anyio portal thread,
so it broke immediately under test. Fixed at the source (curry_core.py,
Curry.__init__) with check_same_thread=False, documented as a second
deliberate vendoring deviation alongside the PR #4 sandbox fix - there was
never real concurrent access here, just an overly strict same-thread
assertion tripping on a thread-identity change with only one logical caller.
Verified: 244 backend tests pass (18 new for the parser + endpoint wiring +
curry tool registration, 4 new for the TUI passthrough); the 12 pre-existing
C/C++/Rust toolchain failures are unrelated and unchanged. Confirmed by hand
over the real HTTP endpoint: successful dispatch, zero tool_request events
(approval bypass working as designed), a format()-dunder exploit attempt
still rejected by the vendored sandbox fix even through the new tool
registration, malformed arguments rejected before ever reaching dispatch,
and an unknown tool name rejected cleanly. Wheel rebuilt and content-checked
(bin/check.sh's gate now also asserts slash_commands.py ships).

Vendors curry_core.py from Athena-Pro/Curry (with the str.format()/format_map()
sandbox-escape fix from https://github.com/Athena-Pro/Curry/pull/4 already
applied) into synapse/, since Curry itself isn't a pip-installable package -
it's meant to be pointed at via a config path, which only works from a source
checkout. Vendoring a single self-contained, stdlib-only file ships it inside
NexusOS's own wheel with no extra dependency to reconcile.
synapse/curry_store.py opens it into a module-level singleton (curry_db) at
import time, the same pattern as memory.store.store and
playbooks.store.playbook_store, and main.py imports it so it's genuinely
initialized at process startup - preloaded, not lazy-on-first-use. Backed by
its own CURRY_DB file (nexus_config.py), separate from memory.db.
NexusOS builds exactly one wheel (py3-none-any, no compiled extensions) -
there is no separate Windows/macOS/Linux artifact; platform differences are
handled by requirement overlays at install time, not by building different
wheels. Verified the same wheel actually carries this correctly: built it,
confirmed twine check passes, confirmed synapse/curry_core.py and
curry_store.py are present in the archive (bin/check.sh's packaging gate now
asserts this too), then installed that exact wheel into a throwaway venv and
round-tripped a declare_constant/get_constant_latest call against it with no
source checkout present - proving "preloaded and ready to be called" holds
from the shipped artifact, not just editable-install execution.
Android/Termux is unaffected by this change in either direction: it already
has a separate, documented, pre-existing blocker in docs/TERMUX.md (no
published Android pydantic-core wheel) that has nothing to do with Curry,
which is pure stdlib and adds no new native/binary dependency.
Scope: preload only, nothing wired into a chat-facing tool yet - no model or
user-authored content reaches declare_function/call_function today.
Verified: 216 backend tests pass (4 new in test_curry_store.py, including a
regression test proving the vendored sandbox fix survived the copy); the 12
pre-existing C/C++/Rust toolchain failures are unrelated and unchanged.

Gives the assistant three new ACTION tools to change its own playbooks,
runtime settings, and (source checkout only) its own source code, all
reusing the existing run_snippet/remember approval framework — but with
a hardcoded floor (self_edit.ALWAYS_ASK_TOOLS) so these three always pause
for per-call human approval regardless of the global action_tool_policy
setting. Flipping that policy for an unrelated tool must never silently
also unlock unattended self-modification.
synapse/self_edit.py is the new module doing the actual work, documented
in the same explicit "here's what is and isn't a security boundary" style
as code_run.py:
- edit_source is confined to settings.project_root via the same
realpath + Path.parents boundary check that just closed a sibling-
directory bypass in /icons/image, plus a denylist of dangerous
subtrees (.git, the venv, node_modules, build output, runtime state).
Gated on settings.source_checkout — refuses cleanly in a wheel
install, where there's no live repo to edit or commit into.
- The model sends full file content, never a diff; the server computes
the diff itself via difflib against what's actually on disk, so a
human reviews ground truth, not a description the model wrote.
- Every applied source edit best-effort commits to git as an audit
trail — independent of, not a substitute for, the approval gate.
- edit_playbook merges instead of replacing (main.py's prior
_persist_playbook did a raw replace, which was only safe because the
frontend form always sent a complete object — unsafe for a tool a
model calls with a partial argument set, so this also fixes that
latent bug). Becoming the active system prompt requires an explicit
make_active flag, never a side effect of an ordinary edit.
- edit_settings reuses the existing _SETTINGS_DEFAULTS allowlist.
The approval UI (Chatbot.jsx) previously rendered a tool call's arguments
as Object.values(args).join(", ") in a single-line badge — unusable for
reviewing a diff. It now renders a real, server-computed preview (diff
for source, before/after for playbook/settings) via a new shared
diff-view.js helper, with a loud banner when a change would become the
active system prompt or touch action_tool_policy/system_prompt. A new
nexus-edit fence (self-edit-langs.js + Markdown.jsx's EditBlock) shows
the same diff after an edit is applied, mirroring nexus-run.
Verified: 212 backend tests pass (29 new in test_self_edit.py; the 12
pre-existing C/C++/Rust toolchain failures are unrelated and unchanged),
57 frontend node:test cases pass (15 new), eslint and vite build clean,
and the full approval-preview render path was exercised against the real
built UI with a mocked SSE stream covering all four preview branches
(source diff, playbook becomes-main, settings policy-change, and a
rejected/failing preview).

/icons/image used a bare string startswith() against allowed roots, so
a sibling dir like /usr/share/icons_evil would pass as if it were under
/usr/share/icons. Switched to the pathlib parents-based check already
used correctly in icons/compositor.py, plus a regression test.
Also stopped three bare `except Exception: pass` blocks (auto model
select fallback, conversation titling) from swallowing errors silently
- they now log to the existing chat trace helper. Behavior unchanged,
just visible when something's actually failing.

Declare Ctrl+C and Ctrl+D as priority Textual bindings so the focused prompt cannot consume them. Drive exit and silent-stream cancellation regressions through Pilot key events instead of calling action handlers directly.
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.

Move chat streaming onto a cancellable async task so Ctrl+C interrupts a pending socket read on macOS instead of waiting for the 120-second read timeout. Add a headless silent-stream regression that verifies prompt recovery and a successful next message.
Capture each stream's conversation ID before starting its worker so /new cannot redirect a later action denial. Add a headless regression that mutates the active conversation while a tool request is in flight.
Keep stream failures in the persistent transcript instead of clearing them with the live preview. Use each tool request's capability token to deny actions immediately until the TUI has an interactive approval flow, and cover both behaviors with focused regressions.
Add a Textual chat interface with threaded SSE streaming, slash commands, interrupt handling, and bare nexus dispatch. Package it behind the tui extra, document usage, and cover command routing, dependencies, and headless interaction with tests.
install-macos.sh mirrors install.sh's split: every portable step - git pull,
venv, pip with the right overlay, npm build - stays in bin/sync.py, shared
with Linux and Windows. The script only does what sync.py cannot do for
itself on a bare Mac, which is install the Homebrew packages needed before a
Python exists to run sync.py with.
Two stages had to learn about darwin. ensure_exec_bits() keyed off
`os.name == "nt"`, which is false on macOS, so it ran the Linux path; and
requirements() had no darwin branch. linux_stage() now no-ops there, which is
what makes skipping the Ollama fetch correct rather than an omission:
bin/fetch-ollama.sh only ships a Linux x86-64 binary, and _ollama_bin() in
synapse/ollama_manager.py already prefers the bundled copy and falls back to
whatever `ollama` is on PATH. On macOS that is the brewed one, with Metal
acceleration and no flags needed.
The XFCE desktop branding is Linux-only and was already gated off macOS the
same way, so there is nothing to install for it here.
install-macos.sh joins the shell-parse list in bin/check.sh.

render_preview validates markup and hands it to the browser, which renders it
in an opaque-origin sandboxed iframe. Nothing executes server-side. That model
fits HTML/SVG/JSX and cannot fit C, Rust or Erlang, which need a real
toolchain - so those get a second tool instead of a widened first one.
The split is the feature: the model picks a track by picking a tool, rather
than picking a `lang` value from an enum where half the entries run
server-side and half do not.
synapse/code_run.py compiles and runs one file in a throwaway directory and
returns a ```nexus-run fence carrying the source and its captured output
together, so a model cannot paste output without the code that produced it.
Backticks in the source are re-encoded as ` - still valid JSON, and it
cannot close the fence early.
It is not a sandbox, and the module docstring says so up front. What it gives
is containment by layers: consent (an action tool, gated by
action_tool_policy, per-call Approve/Deny on "ask"), static screening, a
scrubbed environment in a temp dir, wall-clock and POSIX rlimits, and a
network namespace on Linux where unprivileged userns are available. Screening
is a tripwire against a model reaching for `requests` out of habit, not a
boundary against an adversary; layers 1 and 3-5 are the load-bearing ones.
Backend RUN_LANGS and frontend run-langs.js are separate registries because
the two sides need different things - one executes, one labels - and neither
should depend on the other at runtime. tests/test_tools.py asserts the key
sets and the fence tag stay equal, so drift fails the gate instead of
rendering a run result under the wrong language.
tests/snippet_probes/ is a data catalog rather than inlined cases, so adding a
language is a data change and the meta-tests can assert every RUN_LANGS key
has both a smoke probe and a screening probe. Probes skip cleanly on hosts
without the toolchain.

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.

- 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.

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.

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.

Distilled from the private repo's playbook set with names and personal
specifics genericized. Reuses the same IDs as their private counterparts,
matching the existing main.yaml.

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

Opt-in repair pass: reinstall Python deps on import failure, npm install when
node_modules missing, npm run build when dist missing, fetch Ollama binary.
Plain doctor stays read-only.

Debian apt ships EOL Node 18 which crashes Vite 8. Prep stage installs Node 20
from NodeSource when node is missing or <20; package.json declares engines.

Settings "Auto model routing" picks which installed model fires for chat vs
coding intent when no model is pinned (auto_chat_model / auto_code_model).
_auto_select_model honors the remap; _MODEL_PREFERENCE["code"] prefers real
coder models first.

Windows installer no longer auto-downloads models; points to the Models tab.
synapse/hardware.py detects RAM + best-effort VRAM and a curated catalog;
GET /models/recommended annotates each model with fit (gpu/ram/no); the Models
page shows detected RAM/VRAM with fit badges and per-row Pull buttons.

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.
