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.
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.
