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).
