shadow-testandClaude Opus 5 0a022dfcf0 Let a project turn a globally-enabled Claude Code setting back off
The six boolean settings were plain `bool`s merged with
`if p.x { true } else { g.x }`, so a project could only ever add to the
global set. There was no project value that produced `false` — turning a
switch off at project level simply fell through to the global value and
the control did nothing.

Widen them to `Option<bool>`. `None` means "not set at this level":
inherit the global on a project, leave Claude Code's own default alone
globally. `Some(false)` is a deliberate off and wins outright.

The fingerprint now formats with `{:?}` rather than `{}` — `None` and
`Some(false)` mean different things, and conflating them would leave the
container un-recreated when a project switched from inherit to off.

The project editor grows a third "Global" state per switch; the global
editor has nothing to inherit from, so it stays a plain toggle and keeps
collapsing to null at the default. Its three existing tests passed
unchanged and caught a first attempt that rendered unset as off, which
would have told every user their session recap was disabled.

shadow-testandClaude Opus 5 22d142c70d Shift+Enter newline, OAuth URL truncation, and the auth bridge toggle
Three fixes that all land on the same journey: sign in, paste a prompt,
and have the terminal behave the way every other Claude Code host does.

Shift+Enter inserts a newline
-----------------------------
xterm.js does not consult `shiftKey` for Enter (`Keyboard.ts`, case 13),
so Shift+Enter was byte-identical to Enter and submitted the prompt.
Both terminals now send `\x1b\r` (ESC+CR) instead, which Claude Code
parses as return+meta — the same bytes its own `/terminal-setup` writes
into the VS Code, Cursor, Alacritty and Zed keymaps, so this is in-band
rather than a guess. Not `\n`: Claude Code accepts it, but a shell would
run the line, so the two session types would diverge. Bound in Claude
sessions only for that reason.

`entrypoint.sh` sets `shiftEnterKeyBindingInstalled` in `~/.claude.json`
so the CLI stops printing its "run /terminal-setup" tip. Purely
cosmetic — the decoding is unconditional either way.

Alt+Enter has always done the same thing (xterm ESC-prefixes on altKey)
and was simply never documented. It is now, along with the rest.

OAuth login URL truncation
--------------------------
Two producers wrote one toast slot, last-writer-wins. The OSC 7777 relay
delivers the URL base64-encoded and therefore exact; ~300 ms later the
screen-scraper's debounce fired and overwrote it with a truncated guess
at the same link — a URL that parses, points at the right host, and
authorises nothing. The user is the one who has to notice.

Why the scraper truncated: `ANSI_RE` strips OSC sequences wholesale,
including the OSC 8 hyperlink whose parameter carries the complete URL.
Claude Code slices the *visible* text of that hyperlink to the terminal
width while every emission carries the whole URL in its parameter. The
backend already knew this (`commands/auth_token_commands.rs`); the
frontend did not.

- `urlDetector` now reads OSC 8 targets out of the raw buffer before
  stripping, filtered by a port of `usable_sign_in_link`, and tags every
  candidate with its provenance.
- The prompt slot gained `supersedes`: better provenance always wins,
  worse never does, and between equals only a candidate that *extends*
  what is showing may replace it. That last rule is `extendsUrl`,
  factored out of `pickSignInUrl` rather than copied — same rule, same
  reason, one implementation.
- `flatten` splits on a bare `\r` as well as on `\r?\n`, so a
  `\r`-repainted TUI frame no longer inflates a line past the width and
  suppresses a join that should have happened; and the width is now
  sampled at `feed()` rather than read at `scan()`, so a resize inside
  the 300 ms debounce cannot reassemble 80-column text against a
  120-column rule.

Also corrects the comment claiming `acquire_claude_token` enables the
auth bridge. It deliberately does not, and the module comment in
`auth_token_commands.rs` explains at length why not.

The auth bridge toggle
----------------------
`setAuthBridgeEnabled` and `getAuthBridgeStatus` had zero call sites:
the Rust was complete, the IPC wrapper shipped, and there was nowhere to
click — so the docs told users to "enable the Auth Bridge" for a switch
that did not exist. `AuthBridgeRow` is that switch, in Config → Runtime.
It deliberately does not go through the tab's stopped-only save: the
dedicated command exists so the bridge can be flipped while a login is
hanging in a running container, which is the only moment anyone reaches
for it.

It also subscribes to `auth-bridge-changed`, which the poller has been
emitting to nobody — so a host port the bridge could not take was a
completely silent failure, indistinguishable from a login that hung.

`tunnel.rs` promotes the best-effort `::1` bind failure from debug to a
warning recorded on the port. Half-bound is the failure mode that looks
like success: the status says bridged, and a client that resolves
`localhost` to `::1` without falling back is still refused.

Finally, for a recognised Anthropic sign-in URL the toast now leads with
"In container" and demotes the host "Open". The callback listener is
inside the container, so the container-side browser closes the loop with
no host round trip and no auth bridge; the host button stays as the
fallback. Ordinary URLs are unchanged.

Tests: 402 frontend (was 359), 285 Rust (unchanged).

Review caught that the device guard was wired to the wrong call. The
daemon does not resolve `--device` at create: verified against Docker
29.7, `docker create --device /dev/does-not-exist` succeeds and prints an
id, and runc only resolves the device — and validates sysctls — when it
builds the container. So on a host with no tun module the create returns
fine and `start` fails, which means the explanation never ran and the
user saw the raw daemon string naming a path they would go looking for on
the wrong machine. The unit tests fed the create-side string straight in,
so they confirmed a function no real failure could reach.

Move the guard onto `start_container`, covering create as well in case a
future daemon checks earlier. It no longer takes `vpn_support_enabled` —
`start_container` has a container id and no project, and nothing else in
Triple-C ever requests a device, so an error naming /dev/net/tun is
unambiguous on its own. The test now uses the daemon's verbatim message
via bollard's real Display format.

Also from review:

  * Soften the security claim. Docker does not enable user-namespace
    remapping by default, so this is a real CAP_NET_ADMIN in the initial
    user namespace with only the network namespace confining it. It
    cannot touch host interfaces, but "confers no authority outside the
    container" was too strong: within its namespace it can set
    promiscuous mode and add addresses, routes and NAT on the shared
    docker0 segment, which puts sibling containers — the LiteLLM gateway
    among them — within ARP-spoofing reach, and it can flush netfilter
    rules sandbox mode may rely on. Said plainly in the code, CLAUDE.md
    and HOW-TO-USE.
  * Drop Tailscale from the list of clients needing this. Its
    --tun=userspace-networking mode needs neither the capability nor the
    device, and listing it invites granting NET_ADMIN for nothing.
  * Say in the toggle's own hint that changing it recreates the
    container, matching how every other recreation-triggering setting is
    labelled. The tab's generic "stop the container first" chip does not
    tell the user what is about to happen.
  * Add RuntimeSection tests: saves on, saves off explicitly rather than
    dropping the key, reflects state, is disabled while running, and
    carries the recreation warning.

shadow-testandClaude Opus 5 65a3d4eb29 Let a project's container run a VPN client
Build App (Preview) / compute-version (pull_request) Successful in 4s
Build App (Preview) / create-release (pull_request) Successful in 1s
Build App (Preview) / build-macos (pull_request) Successful in 2m39s

A VPN client installed in a container today starts, runs, and then hangs
until its connection times out. Nothing reports an error: a default
container has no /dev/net/tun to open and no CAP_NET_ADMIN to add an
interface or a route with, and clients surface that as a generic timeout
rather than a permissions failure.

Add an opt-in per-project "VPN support" switch granting the three things
a tunnel needs. They are useless individually, which is why
vpn_host_config() defines the set in one place and the tests assert all
of it:

  * CAP_NET_ADMIN — Docker's default bounding set has net_raw but not
    net_admin, so a client can ping but never connect.
  * /dev/net/tun — passed through from the host so the kernel's tun
    module backs it, rather than mknod-ed inside.
  * net.ipv4.conf.all.src_valid_mark — WireGuard's wg-quick sets this and
    cannot from inside a container, /proc/sys being read-only, so its
    handshakes are dropped by reverse-path filtering.

Off by default and deliberately opt-in: NET_ADMIN lets anything in the
container reconfigure that container's network stack. It is namespaced —
no authority over the host's interfaces or any other container.

Capabilities and devices are fixed when a container is created, so this
is container state and takes the label-and-compare treatment.
triple-c.vpn-support is written unconditionally, false included, for the
usual docker commit reason: a true stamped once would ride the snapshot
image into every future container and make the switch impossible to turn
back off. A missing label reads as false and off is byte-identical to
today, so no existing project is churned.

Requesting the device fails at creation when the host kernel has no tun
module, which would otherwise surface as a project that simply refuses to
start. explain_create_failure() rewrites that one error to name the
switch and the Docker-Desktop-VM-versus-your-machine distinction, and
leaves every other failure untouched.

shadow-testandClaude Opus 5 01a2f6aec8 Add Project Home, Auth Bridge, shared auth token, and Tier-1 polish
Project Home (DESIGN-REVIEW §B2): the project is promoted from a 280px
sidebar card to a first-class main-area view. ProjectCard.tsx (1,257
lines) is replaced by a select-only ProjectRow plus tabs for Overview,
Sessions, Automation, Config and Files. The PortMappings, FileManager
and ContainerProgress modals are absorbed rather than reimplemented.
Config gains a Saved/Saving/Failed indicator — save-on-blur failures
previously reached only console.error.

Tier-1 polish (DESIGN-REVIEW §A): new elevation, muted-accent, disabled
and focus-ring tokens; a global :focus-visible ring with every
focus:outline-none removed; filled buttons moved to --accent-emphasis
and white-on-success toggles retired, fixing three WCAG AA failures
(2.1:1, 2.5:1, 2.4:1); a shared Modal primitive with role="dialog",
focus trap and restore, adopted by all remaining modals; status
indicators that carry a glyph and word rather than colour alone.

Ctrl+Shift+W closes a tab, deliberately not Ctrl+W — that is readline's
kill-word, used constantly in the terminal this app is built around.

Auth Bridge: a general loopback-callback bridge so browser logins run
inside a container (aws sso login, Concourse fly login, claude login)
can complete against the host browser. Listeners are discovered from
/proc/net/tcp{,6} — ss/netstat/lsof are absent from the image — bound on
host 127.0.0.1 only, and tunnelled in over the Docker API via socat,
which keeps working on Docker Desktop where container IPs are not
routable. Falls back to [::1] because Node resolves localhost to IPv6
first, so claude login often binds ::1 alone. Opt-in per project.

This extracts create_attached_exec() and moves the existing terminal
session path onto it, so there is one attached-exec implementation
rather than two.

Shared auth token: `claude setup-token` is run in a container, the token
is stored in the OS keychain and injected as CLAUDE_CODE_OAUTH_TOKEN
into Anthropic-backend projects. Contrary to the initial design note,
setup-token uses an Anthropic-hosted redirect and blocks on a stdin
paste prompt rather than a loopback callback, so a stdin command is
required for the flow to complete.

The token is never logged, never returned to the frontend, and is
redacted from the streamed output with a stateful matcher that withholds
any tail that could still grow into a secret. Change detection uses a
random rotation id rather than a hash, since a hash in a docker-inspect
readable label would be an offline verification oracle.

Frontend 33 -> 51 tests; Rust 34 tests. Both builds clean.
