Change

One chat feature: change model and reasoning effort from the composer through each agent's native menu.

  • Keep current model/effort visible and open Claude, Codex and pi selection menus without clearing drafts or attachments.
  • Route every choice and cancellation through the checked prompt-answer endpoint; never submit digits or use Enter where a client offers a session-only key.
  • Suppress fallback cards and ordinary submit while a recognized-but-unreadable model/effort menu is open.
  • Recover from menu redraws, prompt_changed, failed cancellation and pane switches without leaving an untracked native menu.
  • Scope Escape to the card/composer flow and keep complete labels usable at phone widths and 200% zoom.
  • Update the contract, demo transport, translations, tests and changelog.

Validation

  • TMPDIR=/private/tmp bun run test:unit: passed.
  • bun run typecheck, bun run build, git diff --check: passed.
  • HERDR_TEST_SESSION=herdr-web-ui-test-prompt-pr523-final TMPDIR=/private/tmp bun test ./server/prompt.contract.test.ts: 14 passed against an isolated live herdr session.
  • CHROME_PATH="/Applications/Google Chrome.app/Contents/MacOS/Google Chrome" bun scripts/model-change-demo-regression.ts: passed for Claude, Codex and pi selection/cancellation, failures, pane ownership, phone/offline behavior and 200% zoom.
  • Real client check: pi 0.73.1 opened its /model catalogue in a PTY without making a model request. Installed Claude Code is 2.1.292; an isolated launch stopped at its workspace-trust gate, so its real /effort screen was not claimed as verified. Claude menu parsing remains covered by captured fixtures and the live-herdr contract.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Change models and reasoning effort from Codex, Claude Code, and pi chat composers while preserving drafts.
    • Dismiss model and effort menus with Escape or by clicking outside without changing the selection.
    • Keep selectable model and reasoning controls accessible in compact and zoomed layouts.
  • Bug Fixes
    • Improved handling of menus that change or become stale, including when switching panes.
    • Model and effort controls are unavailable while disconnected, busy, or handling another prompt.

Walkthrough

The composer now supports model and reasoning-effort selection for Codex, Claude Code, and pi. The server parses and answers their menus, including cancellation. Demo transport and browser regression coverage exercise these flows.

Changes

Composer Model and Effort Selection

Layer / File(s) Summary
Prompt contracts and menu detection
shared/protocol.ts, server/commands.ts, server/prompt.ts, server/prompt.test.ts, server/prompt.contract.test.ts, server/AGENTS.md
Prompt metadata identifies model menus and Codex effort-list entry points. Server prompt handling parses Claude effort and pi thinking menus, tracks selection movement, and includes tests for menu choices.
Menu answer and cancellation handling
server/prompt.ts, server/api.contract.test.ts, server/prompt.test.ts, server/prompt.contract.test.ts, src/components/PromptCard.tsx
The answer route accepts cancellation only for recognized menus. It sends Escape and rereads the prompt. Prompt cards support Escape and outside-click cancellation; tests cover cancellation and stale prompt IDs.
Composer controls and pane wiring
src/lib/compose.ts, src/lib/compose.test.ts, src/components/Composer.tsx, src/components/Composer.css, src/components/PaneTerminal.tsx, src/lib/i18n.*.ts, DESIGN.md, CHANGELOG.md, scripts/composer-fit-demo-regression.ts
The composer exposes model and effort controls for supported agents. Pane handlers open menus and poll for prompt state. Eligibility checks, responsive layout behavior, translations, and documentation describe the controls.
Demo menus and regression coverage
site/demo/transport.ts, scripts/model-change-demo-regression.ts, scripts/ci-browser.sh, scripts/composer-fit-demo-regression.ts, docs/development.md
The demo transport serves model and effort menus. Browser tests cover selection, cancellation, draft preservation, pane switching, mobile interaction, and offline behavior; CI runs the regression script.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Feature

Suggested reviewers: devswha

Merge Risk: ⚪ Minimal · up to 17c99

Users can change supported agents’ models and reasoning effort from chat, with the covered dismissal paths preserving drafts. No concrete merge-blocking issue is indicated; the change appears ready for normal merge checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 17c99

The new selection flow retains existing access checks and limits actions to the selected session. No new privilege escalation was established, but interruption and concurrent-access behavior remain only partially verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The new operation targets the supplied pane and changes its native selection state. Reachability inherits existing authenticated device or bridge authority; this PR does not add a separate per-browser pane ownership boundary or a new unauthenticated control channel.

Security Findings and Attack Paths

  • inferred — No introduced approval bypass was established in the inspected cancellation path. Browser-controlled cancellation cannot directly choose a responder: the server obtains it from the current parsed prompt, rejects ordinary approval cancellation, and stops unwinding when a non-model prompt appears. Concurrent native-terminal transitions remain incompletely verified.

Trust Boundaries and Controls

  • observed — The browser supplies pane identity, prompt identity, and an answer request; the server owns responder validation and terminal-key generation. Selection commits recheck the recognized menu and expected cursor row before the first non-movement input.

Resilience and Maintainability Implications

  • observed — An active pane prompt disables model/effort initiation, including while its card is canceling. Duplicate card answers are synchronously blocked, and late card completions cannot clear a replacement prompt. These controls counter the proposed normal outside-click/trigger race without establishing safety for every external-input interleaving.

Hardening Proposals

  • proposed — If simultaneous native-terminal interaction is a supported operating mode, consider binding nested cancellation to an expected parent-menu chain and exercising lost Escape acknowledgements. This would strengthen transition provenance; it is not a demonstrated privilege or approval bypass.

Thanks for this. The server side is careful where it matters most: nothing in the diff sends Enter on a Claude or Codex model list, no digits are sent, and every key goes through POST /api/pane/prompt/answer. One gap needs closing before this merges, and I have a question about the real clients.

Needs a change

1. A Claude effort slider the reader rejects has no guard, so Enter can reach it.
server/prompt.ts:1573 (parseClaudeEffort) returns null in several cases: tied labels (:1587), a label row without adjacent Low Medium High, a cursor glyph other than ▲, or a cursor more than two columns from a label. modelListWaits (server/prompt.ts:1545) was not extended, so for those screens it answers false. Two paths then lead to Enter:

  • server/index.ts:536: with no prompt read and no list waiting, a chat message sent while the slider is still open is typed into the pane and submitted with Enter. On the slider's own footer (Enter to confirm · s for this session only), that Enter is the key that is not session-only.
  • server/prompt.ts:2536: if herdr reports the pane blocked, readPrompt builds the fallback card, and that card offers Enter.

The trigger is ordinary: click the effort control, the composer says "Reasoning menu did not open", the slider is still on screen, and the user types their next message. This is the case claudeModelListWaits exists for on the model list (server/AGENTS.md: "a list the reader cannot take gets no fallback card either"). A scratch test confirms it: for three slider screens the reader rejects, parseInteractivePrompt is null, modelListWaits is false, and parseFallbackPrompt returns a card with the options Enter and Esc. The same hint on an unreadable model list gives modelListWaits true.

Please add a wait guard keyed on the effort footer, used in both places, with a test for a rejected slider (the tie fixture you already have works). Whether herdr reports the pane blocked on this slider is unverified, but the first path does not depend on it.

2. The Claude and pi menus are parsed from screens that were not captured from the real clients.
The PR body says end-to-end selection in installed Claude and pi was not verified. parseClaudeEffort and parsePiEffort (server/prompt.ts:1923) are therefore built on assumed layouts: the ▲ track, the label row, the footer text, and that /effort and /thinking with no argument open a menu at all (src/components/PaneTerminal.tsx:1634). If a client version does not know the command, the text may go to the agent as a message and start a turn. Could you attach a raw screen capture of each menu from a real client and say which versions you tested? I could not verify this either way here.

Smaller notes

  • src/components/Composer.css:1288-1291 and :1311: new rules for data-model="out", but composerModelDraw (src/lib/compose.ts) returns only full, row or no-effort, and this PR removes out from the type. These rules never apply; please drop them.
  • src/components/PromptCard.tsx:109-130: the Escape listener is on document in the capture phase and stops propagation whenever a model card is shown. That takes Escape from anything else open at the time (the slash menu, a dialog). Consider handling it only when focus is in the card or the composer. Unverified in a browser.
  • Same effect: answer is a new function on every render, so both document listeners are removed and added again on each render. A ref to the latest answer would avoid that.
  • src/components/PaneTerminal.tsx:1634: the click is checked against idle/done on the client, then sent as an immediate submit. If the agent starts working between the check and the send, /model may enter the pending list and be delivered later with nobody waiting for the menu. Unverified; worth a sentence on what you expect there.
  • CHANGELOG.md conflicts with v0.4.0 and needs a rebase. The entry format (PR link and by @suho-han) is right.

What is good

  • Cancellation (server/prompt.ts:2772-2794) sends only Esc, rereads the screen before each further Esc, and stops as soon as the screen is not a model menu. A non-model prompt is refused with invalid_answer.
  • The Codex effort entry point reuses the existing pick step, so its key is still read off the screen and a row whose footer offers s never gets Enter.
  • Claude effort ends in s, never Enter. The tie rejection and the redrawn-cursor check are both tested.
  • The model button shows a name only when modelLabel names the id, otherwise the id as received, as src/AGENTS.md asks.
  • Contract test, demo transport answer, ko/ja/zh entries and docs are all there.
  • bun run check fast passes here at the head: 1671 pass, 4 skip, 0 fail. The unit files this touches pass too (prompt 187, compose 29, i18n 16), and typecheck is clean.

Merge status

On v0.4.0 (aca94ee) the only conflict is CHANGELOG.md; everything else merges automatically.

Review follow-up complete at 37eaaa8.

  • Added the unreadable Claude effort-menu wait guard, bounded Pi menu detection, prompt redraw/error recovery, scoped Escape handling and stable callback refs.
  • Removed the unreachable new data-model="out" selectors noted in review.
  • Live-herdr prompt contract: 14 passed. Full unit suite, typecheck/build and the Claude/Codex/pi browser regression passed, including phone and 200% zoom.
  • Real pi 0.73.1 opened /model in a PTY without a model request. Installed Claude Code is 2.1.292, but an isolated launch stopped at workspace trust, so I have not claimed a real /effort capture; that path remains fixture/contract verified.

Thank you for this, @suho-han, and for the careful work on the server side: answering only through POST /api/pane/prompt/answer, never Enter on a model list, and the Esc-only cancel were exactly right.

I'm going to close this one rather than merge it. Changing the model and the reasoning effort from the composer is something I want to build into the composer's existing model button myself, together with the /model cards from #501 and #503, so there is one control for it instead of two paths. That design is still open on my side, and I'd rather not have you keep rebasing this while it is.

Your work here is not lost: the effort-slider reading, the cancel path and the review notes on the wait guard will feed into that change, and I'll credit you in it. Thanks again.

…icks for this session only (#594)

## Change

`/effort` sent from a Claude Code chat was a dead end. It was not in the
chat's slash list, and typed by hand it opened Claude Code's effort
slider in the pane, where no reader knew the screen. herdr reports the
pane idle while the slider waits, so not even the fallback card
appeared, and the level had to be set in the terminal.

This adds a reader for that slider (`claude-effort` in
`server/prompt.ts`), so the existing prompt card shows it, the same way
#501 did for `/model`. Nothing changes on the client or on the wire.

- **What becomes a card.** The slider is recognised by its hint, `←/→ to
adjust · Enter to confirm · s for this session only · Esc to cancel`,
with a line of level names above it, the track with one `▲` above that,
and the `Effort` title. The options are the levels Claude draws (low,
medium, high, xhigh, max on Opus 5.5 and Fable 5.1). `▲` is read as over
the level whose name it is centred on, within 3 columns, else no card.
- **A pick is for this session only.** The answer moves the slider with
`←` / `→` and types `s`. It never sends Enter, which saves the level as
the default for new sessions (per model, in `modelSettings`). Typing
`/effort high` by hand still saves a default, as it does in the
terminal: that is Claude Code's own behaviour for a level typed after
the command.
- **Same guards as the model list.** The slider is read again before the
`s`, also when the pick needs no move, and the letter goes only while
`▲` stands over the chosen level. Each move after the first waits for
the slider to show the one before it. A slider the reader cannot take,
for example level names a narrow pane wrapped, gets no fallback card and
holds pending delivery back (`modelListWaits`), because both end in
Enter.
- **Moves.** `←` / `→` count as moves for this responder only. Elsewhere
they stay a menu's own keys (Claude's question tabs).
- **One card wherever `▲` is.** The card's id does not depend on where
the slider stands, so moving it in the terminal does not replace the
card.
- `/effort` joins Claude's built-in slash list, described in Claude
Code's own words.
- Ultracode (the slider's Tab toggle) is left to the terminal.

Related:

- #523 by @suho-han, closed today, read Claude's effort slider as part
of a composer control for model and effort. Its close comment said the
slider reading would feed into the maintainer's own change, with credit.
This PR is written fresh against Claude Code 2.1.294's screen (#523
could not capture a real `/effort` screen), but it is the same feature,
so the changelog credits it.
- #501 and #503: the `/model` cards this follows (letter `s`, never
Enter, look before the letter).
- #456 and #467: the model and effort shown in the composer's pill. The
pill picks the new level up with Claude's next answer, as it does for a
model.

Known limits:

- #542 applies here too. The guard reads this slider's hint with
`claudeModelListWaits`, so a hint split inside a word, or over more than
six lines, is missed in the same way.
- #469 applies here too. The slider closing between the last read and
the `s` still lets the letter into Claude's prompt.
- A narrow pane's slider was not captured live. A wrapped line of levels
is left to the terminal, and that path is covered by unit fixtures only.
- Models with four levels (Opus 4.6, Sonnet 4.6) were not captured. The
reader takes whatever level names are drawn, but `▲`'s spacing there is
unverified.

## Validation

- `bun run typecheck`: passed. `bun run test:unit`: 1780 passed, 0
failed (before the rebase on 6993563). After the rebase: typecheck
passed and `server/prompt.test.ts` 188 passed, 0 failed.
- `server/prompt.test.ts`: the fixture drawing is checked against a
capture of Claude Code 2.1.294's slider at 120 columns. Tests cover
reading, one id across `▲` positions, keys (`←` / `→` then `s`), no card
and no hold once the slider is answered or under later output, no card
without the session-only key, a wrapped level line (no card, still
holds), `▲` between two levels, and two route cases: a pick two levels
left (`left, left, s`), and `▲` moved in the terminal mid-pick (one
arrow, no letter, 409).
- Real Claude Code 2.1.294 in an isolated herdr 0.9.3 session
(`herdr-web-ui-test-effortprobe`), through this branch's `createServer`.
`GET /api/pane/commands` lists `effort`. `/effort` then `GET
/api/pane/prompt` gave the card with five levels. Answering xhigh and
then low over `POST /api/pane/prompt/answer` printed `Set effort level
to xhigh (this session only)` and `Set effort level to low (this session
only)`, and the banner read `with low effort`. `~/.claude/settings.json`
kept its modification time through every probe and pick.

…e notes (#598)

Two changes the owner asked for, one commit each.

## 1. Clipboard from a pane (OSC 52) is on by default

#570 turned **Settings → Terminal → Clipboard from a pane** off by
default, so copying from vim, tmux and Claude Code silently did nothing.
It is on again; the switch stays for anyone running output they do not
trust.

**Migration: a new storage key.** Settings are saved as one whole
record, so any 0.4.1 install whose user changed *any* setting has
`terminalOsc52: false` stored without choosing it. The choice now lives
under `paneClipboard` (default `true`) and `terminalOsc52` is ignored
and dropped by `sanitizeSettings`, which already discards unknown keys.
That is the simplest correct option:
- a 0.4.1 record loads as on (its `false` cannot be told apart from a
real choice, so it is not trusted);
- an off chosen from now on is written under `paneClipboard` and stays
off across saves and reloads;
- no version field or one-off migration state is needed. A settings
version would do the same with more code.

Known edge: a tab still running the 0.4.1 bundle that saves settings
writes its own record, which has no `paneClipboard`, so a new "off"
would read as on again until it is re-chosen. Tabs pick up the new
bundle on reload, and settings already have no cross-tab sync (each tab
saves its in-memory record), so this is no worse than any other setting.

Tests (`src/lib/settings.test.ts`, "clipboard from a pane"): fresh
default on; a 0.4.1 record with `terminalOsc52: false` loads as on; an
off chosen after the change survives a save, a reload and an unrelated
change. A mutation that falls back to the old key fails the second case.

Also: the setting's description and code comments say what is true now,
ko/ja/zh entries are updated, and there is a CHANGELOG line under
Unreleased → Changed. No doc in `docs/`, `DESIGN.md`, `INSTALL.md` or
`README.md` mentions the default.

## 2. Patch-note style GitHub release notes

`scripts/release-notes.ts` printed the whole CHANGELOG section (181
lines for v0.4.1). It now prints the English lists from
`release-summaries.json` (`### New features`, `### Improvements`, `###
Bug fixes`, a list with no lines left out), then the full section inside
`<details><summary>Full changelog</summary>` with blank lines around it
so GitHub renders the markdown. Lines come through `readSummary`, so
they are trimmed and capped exactly as an install shows them. Every
validation is unchanged (version format, the three version sources,
exactly one heading, nonempty notes, all four languages).
`scripts/release-notes.test.ts` pins the shape, the order and an empty
list left out. `docs/development.md` → Releasing and `scripts/AGENTS.md`
describe the new body.

The published v0.4.1 release is not touched here; the lead regenerates
it after the merge.

### v0.4.1 rendered with this script (`bun scripts/release-notes.ts
0.4.1`)

### New features

- Typing /effort in a Claude Code chat opens a card to pick the effort
for this session
- Settings → Appearance can keep waiting and the latest agents on top of
the Agents list
- A finished agent you opened in the web UI can lose its dot, as it
would in herdr (opt-in)
- The guide shows how to give the app a public HTTPS address with Portal

### Improvements

- A wrong access token waits longer after five tries, up to a minute
- A program in a pane copies to your clipboard only once you allow it in
Settings → Terminal
- Dialogs keep Tab inside them, and screen readers announce tabs, panes
and status lines
- Add PC, Reconnect PC and Update remote bridge open as a bottom sheet
on a phone
- Updating a remote PC that is already current reuses its bridge without
a new download
- Alerts go only to https push services and never follow a redirect
- Long drafts wrap, and the scrollbar no longer covers text when the
page is zoomed

### Bug fixes

- A long line of unclosed brackets or broken escape codes no longer
freezes the chat
- On Windows, more Claude Code and Codex panes show their chat instead
of an error
- Your own devices are recognised by their Tailscale login again,
without pairing
- A Claude Code chat shows what a slash command answered, and /goal is
suggested
- Settings, the palette, Add PC and file previews stack in order; Escape
closes the top one
- The plugin's start keeps the app on its port while herdr is away
- A secret or typed text no longer reaches a pane you have already left
- Gajae Code's selection and startup menus show their choices, not only
arrow keys

<details><summary>Full changelog</summary>

### Added
- `/effort` sent from a Claude Code chat opens a card with the effort
levels, low to max, so the
level no longer has to be set in the terminal. A pick applies to this
session only, as a pick
from the `/model` card does, and leaves the default for new sessions
alone. `/effort` is also in
  the chat's command list now.

  [#523](#523) by @suho-han)
- Settings → Terminal has a **Clipboard from a pane** switch, off by
default: a program running in a
pane can no longer put text on your clipboard unless you turn it on.
Programs that copy this way
  (vim, tmux, Claude Code) copy again once it is on.
  ([#570](#570) by @radicor)
- The guide's **Behind a reverse proxy** shows how to give the app a
public HTTPS address with
[Portal](https://github.com/gosuda/portal-tunnel) v2.6.1 or later,
behind a long random token
  and with a visitor's `Tailscale-User-Login` header dropped.
([#229](#229) by
@rabbitson87)
- **Settings → Appearance → Agents order → Activity** keeps a waiting
agent on top of the Agents
list and orders the rest by their latest state change, as herdr's agents
panel keeps the latest
work in view: the agent you just sent a message to stays on top while it
runs and after it
finishes, and a new one starts there. herdr's own order and the
workspace rows are unchanged.
  **Workspaces** (herdr's order) remains the default.
([#529](#529) by
@phirschybar)
- **Settings → Appearance → Quiet opened finishes** (off by default): a
finished agent you have
opened in the web UI loses its dot and reads as ready, as viewing it in
herdr would make it.
herdr's DONE otherwise stands until herdr itself shows the pane. It is
remembered per PC in
this browser. ([#529](#529)
by @phirschybar)

### Changed
- A wrong access token is refused with a growing wait after five tries,
up to a minute, whether it
is typed into the sign-in form or sent with a request. Each visitor
behind `tailscale serve` has
their own count, and a browser holding an old token never stops you
signing in with the new one.
  ([#570](#570) by @radicor)
- The app now sends itself a Content-Security-Policy, so third-party
content rendered in a chat —
  math, agent marks — cannot run script in the app.
  ([#570](#570) by @radicor)
- A web-push subscription must be an https endpoint.
  ([#570](#570) by @radicor)

### Fixed
- Gajae Code's selection menus show their choices instead of only
arrow-key buttons, including
startup selectors shown before the pane reports that it is waiting.
Answers move to the selected
  row and recheck the menu before confirming.
  ([#593](#593))
- Secret input and the Codex follow-up fallback validate the live
screen, so a password
prompt or collapsed question queue in scrollback cannot send input into
the current program.
  ([#566](#566))
- The PC's Tailscale login is read from a real Tailscale user id. These
ids are too large for a
JavaScript number, so the owner was not recognised and the owner's own
devices had to pair. Two
  logins with neighbouring ids are also no longer taken for one.
  ([#572](#572))
- On Windows, a Claude Code pane started with a second account's
`~/.claude-*` directory as its
`CLAUDE_CONFIG_DIR` shows its chat. Before, the pane fell back to
`~/.claude`, so the chat said
**Conversation unavailable** and only the terminal worked. Windows does
not let the server read
another process's environment, so the store is the one among the
server's own
`CLAUDE_CONFIG_DIR`, `~/.claude` and the `~/.claude-*` directories
beside it that holds the
Claude process's own record, checked against the time the process
started. A directory
elsewhere is not looked in. Claude Code processes reported as
`claude.exe` are
  recognized too.
([#563](#563) by
@David-Sousa-Web)
- A long line of brackets, `\(` or underscores that never close, as an
agent prints in a log or a
minified file, no longer freezes the chat: a megabyte of them took a
minute or more to read, and
  now takes milliseconds. What every message shows is unchanged.
  ([#574](#574))
- On a mirrored pane (Windows, where herdr cannot attach a terminal),
text typed while a message
was still being sent no longer reaches the pane once you have left it,
or left it and opened it
  again, before the text's turn came.
  ([#576](#576))
- The plugin's `start` keeps the app on its port when the app's own
server holds it but cannot
reach herdr. It used to move the app to another port beside the running
one and blame another
program; now it says that the app runs there without herdr and exits,
and the app answers
  again on its port once herdr is back.
  ([#577](#577))
- On Windows, a Codex pane shows its chat when Codex stored its paths
with the `\\?\` prefix, as
it does for a canonical Windows path (`\\?\D:\work` for `D:\work`).
Before, the chat said
**Conversation unavailable**: the session's file seemed to lie outside
Codex's store, and none of
  the threads matched the pane's directory as herdr reports it.
([#582](#582) by
@David-Sousa-Web)
- In a Claude Code pane, the chat shows what a slash command answered,
so a `/goal` that Claude
Code refuses says why in the chat instead of only in the terminal.
`/goal` is also among the
  commands the message box suggests.
  ([#583](#583))
- Settings opened over a file preview is visible above it; Escape and
Back close Settings
first, preserving the preview and its history entry until the file
itself is closed.
  ([#568](#568))
- Command palette buttons keep their native Enter action; IME commit and
cancel keys
stay with text input, and arrow navigation keeps the selected result
visible.
  ([#567](#567))
- Long drafts in the message box wrap and keep a narrow scroll cue in
reserved space, so the
  scrollbar no longer covers text at fractional zoom.
([#522](#522) by @suho-han)
- A secret sent from a pane you then left and opened again, while
another browser kept the pane
open, is no longer typed into the pane: you send it again from the pane
you opened.
  ([#588](#588))
- A Claude Code slash command whose answer holds a long run of broken
terminal escape codes no
longer stalls the server while the chat reads it. Its answer also drops
a link cut off before
its end and a stray `B` after a charset switch, and an answer with both
output and errors
  shows both.
  ([#588](#588))
- The command palette opened over Settings and a file preview shows
above both, instead of
  taking the keyboard unseen beneath them.
  ([#588](#588))
- The plugin's `start` no longer takes another program on the app's port
for the app because
its answer says `ok`: it treats it as any other program there, moving
the app to a free port,
  or saying the port is taken when `PORT` is set.
  ([#588](#588))
- A 500 from the server no longer repeats the system's own error text,
which carried absolute paths
and the herdr socket location; it names a short id you can quote in a
bug report instead.
  ([#570](#570) by @radicor)
- Settings, the command palette, the file viewer, the file browser and
the new-workspace dialog keep
  Tab inside them and give the focus back to whatever opened them.
  ([#570](#570) by @radicor)
- The tabs of a workspace name the pane region they govern, so a screen
reader announces the tab and
  the pane together.
  ([#570](#570) by @radicor)
- Agent headings in a chat no longer pose as the app's own page
structure; they sit below the app's
  own headings and look the same as before.
  ([#570](#570) by @radicor)
- The "reconnecting" line and the composer's terminal-only hint are
announced when they appear.
  ([#570](#570) by @radicor)
- A chat locked out by the token gate, the "Last checked" line under
Settings → About (with its
date in your language) and a remote PC's state word in the sidebar are
translated like the rest of
  the UI.
  ([#570](#570) by @radicor)
- The alerts menu item now says the same thing the same way in every
state.
  ([#570](#570) by @radicor)
- Held terminal input typed while disconnected is forgotten after a day.
  ([#570](#570) by @radicor)
- A link printed in the terminal opens only if it is an http(s) address,
on both link paths.
  ([#570](#570) by @radicor)
- A second tab open on one pane no longer sends a message the first tab
is already sending: it
sees that send on its way and holds back. Two tabs that press Send at
nearly the same moment can still
  both send it.
  ([#570](#570) by @radicor)
- A row's ⋯ menu is capped to the room its button leaves and scrolls
instead of being cut off by the
viewport, so the pane picker of a tab with many panes keeps every entry
reachable with the pointer
as well as the keyboard. Before, items below the fold were rendered but
unreachable.
  ([#570](#570) by @radicor)
- A row menu open while the window crosses the 640 px breakpoint now
switches between bottom sheet and
  popover instead of keeping the form it opened with.
  ([#570](#570) by @radicor)
- The workspace drawer a narrow window opened is closed again when the
window is widened past 768 px,
  so narrowing it no longer brings back a drawer and its scrim unasked.
  ([#570](#570) by @radicor)
- **Add PC**, **Reconnect PC** and **Update remote bridge** open as a
bottom sheet on a phone, like
every other dialog, and keep clear of the on-screen keyboard. Before,
the one native dialog stayed
  a centred card on a phone.
  ([#570](#570) by @radicor)
- **Remove PC**'s first click is a quiet ghost button that only arms the
removal; the second is the
  red one, as revoking a device already was.
  ([#570](#570) by @radicor)
- A PC's rename, connect and disconnect buttons disable while their
request is in flight, so a double
  click no longer sends two overlapping requests.
  ([#570](#570) by @radicor)
- A failed pane or workspace rename keeps the field open with what you
typed, so a network blip no
  longer makes you write the name again.
  ([#570](#570) by @radicor)
- A workspace reorder that fails no longer undoes a later, successful
reorder.
  ([#570](#570) by @radicor)
- A tab watching several busy panes gives up its oldest cached
conversation answers when they grow
  past a byte budget, not only past sixteen of them.
  ([#570](#570) by @radicor)
- The usage meters' note is the same size as every other advisory and
empty state.
  ([#570](#570) by @radicor)
- The PDF viewer's page colour, the pill radii, the tab dot and the
pairing-code size come from
design tokens now, and the pairing code follows the compact density
setting.
  ([#570](#570) by @radicor)
- Updating an already current remote bridge verifies and reuses it
without downloading or
restarting it again, while a bridge from a newer app is left running
instead of downgraded.
A PC that waits on such a conflict says so in the sidebar and under the
header, with a
  **Reconnect** button, instead of asking for setup approval.
([#519](#519) by @suho-han)
- A wrong access token sent through a proxy on this PC with a made-up
`X-Forwarded-For` address
that itself says " via " now counts against the limit every visitor
through that proxy shares,
like any other wrong token. Before, each such try started a fresh count.
  ([#592](#592))
- A web-push subscription must be an https address, with no exception
for this PC, and an alert is
never sent on where a push service redirects it, so an alert can never
be posted to a service
running on this PC.
([#592](#592))
- In the **Add PC** dialog opened over a file preview, Tab moves through
the dialog's own controls
and Escape closes the dialog alone, leaving the preview beneath it open.
  ([#592](#592))

## Checks
- `bun run check fast`: ok (1817 pass, 6 platform skips, 0 fail).
- No browser regression covers OSC 52 (`terminal-copy-regression.ts`
covers drag and Ctrl+C copy), so none was run for it.

## Codex review (gpt-6-astra, read-only)
- **Fixed** (P2): summary text was put into the markdown as-is, so
`"…\n\n<!--"` could hide the whole changelog fold. The gate now refuses
a summary line with a line break in any language, and the English lines
escape `<`. A test covers both and fails without the fix.
- **Declined, documented** (P2): a tab still on the 0.4.1 bundle that
saves settings drops `paneClipboard`, so a new "off" reads as on until
it is chosen again. A versioned storage key would stop that, but then
every setting changed in such a tab would be lost instead. It lasts only
until that tab reloads, and every setting added before this one had the
same gap.
- **Pre-existing, not in this diff** (P2): settings have no cross-tab
sync, so a stale tab's next save writes its own copy of every setting,
this one included. Reported to the lead as a follow-up.
