Change

Another PC's bridge was trusted to end its answers at a sensible size: a timeout bounded how long an answer could take, not how much of it the server held in memory. Every buffered answer from a bridge (and the release's bundle manifest) is now read through a small byte-capped reader (server/remote-json.ts). It counts the decoded bytes as they arrive, cancels the stream at the first byte past the route's ceiling, and decodes or parses only after that check.

Answer Where Ceiling
Bridge identity (GET /api/bridge) MachineManager.verify 64 KiB
Bridge error body (read only for its code) MachineManager.verify 8 KiB
Session snapshot (GET /api/session) MachineManager.refresh 64 MiB
Release bundle manifest (HTTPS) bundleFile 1 MiB
Buffered PC proxy answers handleMachineRequest 64 MiB
A watching device's pane/prompt (parsed to remove hidden fields) handleMachineRequest 1 MiB
  • An answer exactly at its ceiling is accepted; one byte past it fails without being parsed. A Content-Length past the ceiling is refused before reading. An absent, smaller or compressed length is measured from the stream instead.
  • Failures use fixed messages that repeat none of the answer. The proxy answers 502 remote_response_too_large. When a watched prompt cannot be parsed for redaction it answers 502 remote_response_invalid, so a watcher never receives an unredacted prompt.
  • Known bridge error codes (missing socket, herdr not answering) are still recognised from the bounded error body. Unread failure bodies are cancelled. Snapshot generation and stale-refresh ordering are unchanged.
  • Unchanged: fs/file still streams with its ranges, a 304 stays bodyless with its ETag, and local manifests and bundle downloads work as before.
  • No new layout or control. The two fixed sentences (from server/remote-json.ts, and now also the proxy's 502 message) are shown in the UI language wherever they appear, with ko/ja/zh entries:
    • a PC's error (sidebar state line) and its setup job's error (PC dialog), through machineErrorText in src/lib/userError.ts, which passes any other words through;
    • any request the PC proxy refused: errorFrom in src/lib/api.ts maps remote_response_too_large / remote_response_invalid to the translated sentence. That is the detail userErrorMessage, userFailure and the dialogs reading ApiError.detail show under their own generic sentence (for example New workspace on that PC).

Design

None of the reference coding-agent apps (the Codex and Claude apps, Paseo, T3 Code) relays a second PC's bridge, so there is no app precedent for this case. It follows this app's own rule in DESIGN.md ("Messages say only what the person needs now": a known cause is the sentence). The new DESIGN.md entry under that rule records it: one of two fixed sentences in the user's language, placed where each surface already puts the server's words, never with any of the answer, its address or its size. Nothing new is drawn.

Validation

  • Locally: bun run typecheck exit 0, and the conventions tests 40 pass, 0 fail. The full fast check runs in this PR's CI.

  • bun test ./server/remote-json.test.ts ./server/machines.test.ts ./server/machines-refresh.test.ts ./server/machine-update.test.ts ./server/remote-bundle.test.ts ./src/lib/userError.test.ts ./src/lib/api.test.ts ./src/lib/i18n.test.ts: 159 pass, 0 fail. The new cases fail on the previous code. They cover:

    • cap plus one is cancelled without decoding, and an exact cap split inside UTF-8 characters is accepted;
    • a dishonest, absent or gzip-decoded length is still measured;
    • bridge errors are bounded without echoing secrets, and a stale oversized refresh does not replace a newer snapshot;
    • a watched prompt is redacted after the bounded read, and file streaming and 304 behave as before;
    • the proxy's two 502 errors reach userErrorMessage / userFailure detail in Korean when the UI is Korean, and as the server's sentence in English.

    Early stops are proven by the peer stream's cancellation receipts, not by timing.

  • bun run check run bun test --timeout 15000 ./server/api.contract.test.ts: the new safe-502 contract case passes. The only failing case is the existing workspace file-search test (pane/files returns no match), which fails the same way on main.

  • Visual QA of the sidebar state line, the PC dialog and the New workspace dialog on the built client with a test-owned fixture: 54 captures. They cover connected, overflow error, loading, offline, observe-only, long text, scrolled to end, PC dialog error, and a New workspace error from the real proxy refusing a 64 MiB + 1 answer. Each is at 390 (iPhone 14, DPR 3, touch) and 1440, in light and dark, plus Korean at 390. The Korean frames show the translated sentences, with no English sentence in the dialog. No frame overflows horizontally. Detail text contrast is 5.97 / 5.82 in the sidebar and 6.75 / 7.15 in the New workspace dialog (light / dark).

This touches an HTTP contract and the data a watching device receives, so it waits for a real review.

Ready for maintainer review; do not merge.


Plan todo 33 of the AoE borrowings plan. Independent verification confirmed it, two independent visual reviews passed where the change is visible, and a full CI run on this branch passed before this PR was opened: https://github.com/devswha/herdr-web-ui/actions/runs/39695363025

A timeout bounded how long another PC's bridge could take to answer, not
how much of that answer the server held. Bridge identity and error
answers, session snapshots, the release bundle manifest and every
buffered PC proxy answer are now read through server/remote-json.ts,
which counts the decoded bytes as they arrive, cancels the stream at the
first byte past a fixed ceiling, and only then decodes or parses.

Ceilings: bridge identity 64 KiB, bridge error 8 KiB, bundle manifest
1 MiB, session snapshot 64 MiB, buffered proxy answers 64 MiB, and a
watching device's pane/prompt 1 MiB (it is parsed to remove hidden
fields). A Content-Length past the ceiling is refused before reading; an
absent, smaller or compressed length is measured from the stream.

Failures use fixed messages that repeat no URL, token or answer text.
The proxy answers 502 remote_response_too_large, or 502
remote_response_invalid when a watched prompt cannot be parsed for
redaction, so an unredacted prompt is never passed on. Known bridge
error codes are still read from the bounded error body, unread failure
bodies are cancelled, and generation and stale-refresh ordering are
unchanged. fs/file still streams with its ranges, 304 stays bodyless
with its ETag, and local manifests and bundle downloads are untouched.

Checked with bun run check fast; bun test on remote-json, machines,
machines-refresh, machine-update and remote-bundle (the new cases fail
on the previous code); and the api.contract test on the isolated herdr,
where only an existing workspace file-search case fails, as it does on
main.
The fixed sentences server/remote-json.ts uses for an oversized or unreadable answer from another PC reach a PC's error and its setup job's error, which the sidebar and the PC dialog showed in English. machineErrorText translates them at those surfaces, with ko/ja/zh entries, and passes any other words through.
…nguage

The proxy's 502 remote_response_too_large and remote_response_invalid
carried their own English sentences, which every error surface showed
as detail beneath its translated sentence. The proxy now answers with
the remote-json error's fixed message, and the browser maps both codes
to the translated sentences where it builds an ApiError, so
userErrorMessage, userFailure and the dialogs that show ApiError.detail
all read them in the UI language. DESIGN.md records the rule.

📝 Summary

Summary by CodeRabbit

  • Bug Fixes

    • Remote PC responses are now size-limited and safely cancelled when they exceed accepted limits.
    • Unreadable or oversized responses show clear, localized error messages without exposing response contents, credentials, or sensitive prompts.
    • Refreshes and remote operations preserve the last known state and can recover after a rejected response.
    • Improved handling for unavailable PCs and malformed remote responses.
  • Documentation

    • Added guidance and changelog details for oversized or unreadable remote responses.

Remote responses are now read under per-response byte limits, with oversized or invalid JSON mapped to fixed errors. Bridge verification, session refresh, bundle manifests, and machine proxy paths use bounded parsing or discard responses. The UI translates the new error messages, and tests cover cancellation, redaction, and recovery.

Changes: Remote response bounds

Layer / File(s) Summary
Capped response reading
server/remote-json.ts, server/remote-json.test.ts
Added per-response byte limits, capped stream reading, fixed errors for invalid or oversized JSON, and cancellation of unread bodies. Tests cover exact limits, decompressed bytes, Content-Length handling, and cancellation.
Bound bridge, refresh, and manifest responses
server/machines.ts, server/remote-bundle.ts, server/machine-update.test.ts, server/machines-refresh.test.ts, server/machines.test.ts, server/remote-bundle.test.ts
Bridge verification, session refresh, and bundle manifest loading now use capped parsing or discard unsuccessful response bodies. Tests cover size rejection, cancellation, secret exclusion, and refresh recovery.
Bound and sanitize machine proxy responses
server/machine-api.ts, server/api.contract.test.ts, server/machines.test.ts, DESIGN.md, changelog.d/remote-control-body-limits.md
Machine proxy responses use capped reads and distinct errors for oversized or invalid responses. Watched prompts retain field redaction. Tests cover proxy limits and sanitized errors; the design note and changelog document the handling.
Translate remote response errors
src/lib/api.ts, src/lib/userError.ts, src/lib/i18n.*.ts, src/components/MachineDialog.tsx, src/components/MachineSidebar.tsx, src/lib/userError.test.ts
Known remote-response errors map to localized messages in API error handling and machine UI surfaces. Tests cover translation and preservation of unrelated error text.

Since #1588 every buffered answer from another PC's bridge is read
through the byte-capped reader, but this branch's source check read the
bridge's /api/health whole with response.json(). It now reads it through
readCappedJson with its own 64 KiB ceiling (a health answer is well under
2 KiB), and drops a body it will not read. An answer past the ceiling
proves nothing, as any other failed check does.

## Change

Release 0.4.13: everything merged since 0.4.12 (136 commits, 109
changelog entries). Metadata only; no code changes in this PR.

Left out of this release on purpose (still open): #1542, #1597, #1598,
#1579, and the outside contributors' PRs not yet reviewed or held (#1427
#1442 #1516 #1520 #1521 #1527 #1528 #1530 #1540 #1560 #1629 #1632
#1634).

### Metadata
- `package.json` and `herdr-plugin.toml`: 0.4.13.
- CHANGELOG: 87 `changelog.d/` fragments folded into `[0.4.13] -
2026-10-22` by `scripts/changelog-fold.ts`, with `by @login` credits on
the 36 links of outside contributors' PRs; `changelog.d/` holds only
README.md. Docs/test-only PRs without a fragment (#1395-#1398, #1439,
#1440) are not listed, as before.
- `release-summaries.json`: 0.4.13 in en/ko/ja/zh (8 new, 6 improved, 8
fixed; equal in every language, each <= 90 chars). The first line tells
that the app is now called Ovis (#1454) and installs and updates as
before.
- `REMOTE_BUNDLE_VERSION` 31 -> 32: `server/` and `shared/` changed
since remote-v31.
- Telemetry: `telemetry/worker.ts` and `shared/telemetry.ts` are
unchanged since the recorded deploy, so no Worker redeploy.

### After merge
1. Push `remote-v32` on the merge commit and wait for **Remote PC
bundles** to publish it.
2. Merge nothing touching `server/`, `shared/`, `bun.lock` or `patches/`
until the Release run is done.
3. `gh workflow run release.yml --ref main -f version=0.4.13`.

## Validation
- `bun scripts/release-guards.ts`: "Release 0.4.13: remote bundle,
telemetry Worker and release metadata are in order."
- `bun scripts/release-notes.ts 0.4.13` renders the three English lists
and the folded changelog.

<details><summary>Changelog (0.4.13)</summary>


### Added
- Claude Code, grok and Antigravity messages in Chat offer Rewind in
terminal: it sends nothing,
preserves your draft and opens the pane's terminal with a hint to run
the agent's own `/rewind`.
Chat follows the native conversation when the agent records its new
branch.
  ([#1500](#1500))
- Chat sends wait while Claude Code's rewind dialog is open in the
terminal, so a message cannot
  land in the dialog's own text field.
  ([#1500](#1500))
- Sending a bare `/goal` to Claude Code from Chat now shows its goal
status (the condition and how
long it has run, or that no goal is set) in a card with Close, instead
of leaving the dialog in
  the terminal.
  ([#1450](#1450))
- Command Code (`cmd`) agent panes now show their conversation in the
web UI: transcript
resolution from `~/.commandcode/projects/`, `/tree` branch projection,
model and context
window from Command Code's catalog, permission prompts, and skill
discovery.
([#1399](#1399) by
@diegolhambi)
- An ordinary command sent from Chat says what became of it under its
bubble, from evidence only:
accepted, waiting for your answer (with a way to the card), done with
what showed it, runs in
the terminal (with Open Terminal), or no result seen. A command the
agent keeps no transcript
  turn for still shows its sent row. A terminal screen that
changed after the send folds under the chip as an unconfirmed preview,
never proof that the
command finished. Terminal-only commands instead leave one quiet row
with Ran in terminal and
Open Terminal, without outcome chips or unconfirmed previews. Hermes
informational result cards
  keep showing what the agent printed.
  ([#1450](#1450))
- Settings → Terminal → Follow herdr's focus: when herdr moves to
another pane (a click in its
window, `herdr tab focus`, a script), this device opens that pane too.
Off by default, and set per
  device, so a phone open on another pane stays there.
  ([#1432](#1432))
- Hermes `/help`, `/status`, `/version`, `/profile` and `/reload-skills`
sent from Chat show what
Hermes printed in a card closed with Dismiss, which sends nothing to the
pane.
  ([#1450](#1450))
- Chat lists the commands and skills an OpenCode v2 pane's own
background service reports for its
folder, refreshed when they change, and settles a command it sent from
that session's own events.
The service is only read, never started, and only when it is the process
its service.json names.
  ([#1489](#1489))
- An `@skill` sent from Chat to OpenCode v2, at once or queued, is typed
through OpenCode's own
autocomplete so the skill is attached; when the row does not show, the
message says the skill
  went as plain text and points to the terminal.
  ([#1489](#1489))
- An OpenCode 1.x question is a card in Chat with each option and its
description, answered from
  the card.
  ([#1489](#1489))
- Chat lists a Codex pane's skills as the running Codex daemon of that
pane's own Codex home reports
them (Codex 0.157 or later; on Linux, or when the server's Codex home is
set), and a gjc pane's
skills as the SDK broker it is bound to reports them, asked through the
gjc CLI in the background.
The daemon and the broker are never started for this; without one, the
skills read from disk stay.
  ([#1489](#1489))
- New workspace and New tab start an agent with its model, effort and
first message where the
agent's command line takes them (Claude Code and Codex: `--model` and
the effort level; Codex also
takes the message as its own argument, behind `--` so a message like
`logout` is never a command).
For Claude Code and every other agent the message is queued on the PC as
the pane's first pending
message and sent once when the agent is ready, through the page that
started it; it shows as a
pending message that can be discarded or sent now. If that page
disconnects, reloads or leaves the tab
first, the message is held, never sent on its own, until someone sends
it now or discards it. A message the PC
could not queue, or one an older PC ignores, stays in the new tab's
message box and the dialog says
so. Pending first messages are kept in memory: restarting the web UI's
server drops them. A Codex
message with a tab or a line break is sent as the first message rather
than on its command line,
and the PC refuses launch arguments with control characters, an unknown
effort level or a model
  that is not one word. Under the message, the agent's skills in the
folder are listed before it runs, each a chip that puts the skill as the
agent types it into the
message (`$name`, `/name`, or `@name` for OpenCode 2). A first message
to OpenCode attaches its
`@skill` as any Chat send does; before OpenCode has a session nothing
tells its version, so the `@`
  is sent as the plain text it is.
In a desktop window the chat's composer can show a New tab with an
agent… button that opens the
dialog on the pane's workspace; it is off until turned on in Settings →
Chat → Composer (New tab
  button), and the tab menu opens the dialog either way.
  ([#1512](#1512))
- omp's `/handoff` runs from Chat, with or without focus instructions:
while omp writes the
handoff document, Chat shows a card that cancels it, and afterwards Chat
stays on the same
  conversation, which omp compacts in place.
  ([#1450](#1450))
- omp's model picker shows in the chat as a card, as Claude Code's,
Codex's and OmO's lists do: pick
a model and it is picked for the session, the model in use named on the
card. `/model` sent from
an omp chat opens it: the chat sends it as `/switch`, because omp's own
`/model` opens its role
  hub, whose picks are saved as the default for later sessions.
([#1377](#1377) by
@evanwy0223)
- OpenCode 2.0 or later: its questions are answered from the chat's
prompt card through OpenCode's
own background service instead of keystrokes, one question at a time
with Back to change an earlier
answer, and sent together after the last. Permissions, OpenCode 1 and
other prompts keep the
  existing generic fallback card and Terminal.
([#1257](#1257) by
@bardiz12)
- HTTP requests and WebSocket handshakes now carry request IDs and write
bounded completion
records in the app's state directory, so the owner can correlate a
response with its request.
  ([#1558](#1558))
- A workspace's row menu has Earlier sessions…: the sessions each agent
kept for the workspace's
folder, read from the agent's own store on the PC, newest first with the
title, the first prompt
and the time. Resume starts the agent on that session in a new tab of
the workspace; a session a
pane already shows is opened by selecting that pane instead. Picking
`/resume` in the chat's menu
opens the same list, and the terminal command's row offers it. A PC
whose bridge cannot list
  sessions yet has no such item.
  ([#1494](#1494))
- Agent rows show what herdr plugins report on a pane, such as the Quota
plugin's usage left or a
task's progress, in a small dim line under the row. They follow the
`$name` tokens of your herdr
`[ui.sidebar.agents]` rows (every token where none are set), change
live, and say a long value
whole in the tooltip and in a phone's ⋯ sheet. A line a plugin reports
for the agent now updates
  as soon as herdr says it.
  ([#1341](#1341))
- `HERDR_WEB_TAILSCALE_HTTPS_PORT` names the HTTPS port the installer
publishes the app on with
`tailscale serve`, so 443 can stay free for something else. Settings →
Phone & devices suggests
that port too. When another service already uses it, the installer stops
and says so instead of
taking another port, which would move the address an installed app
opens.
  ([#1433](#1433))

### Changed
- The chat's `/` menu lists the commands that run in the terminal apart,
last, under Terminal
commands, each with a Terminal badge, as the PC's command catalog
describes them. Pick or type
one and send it normally: once accepted, the pane's own terminal opens
over the chat, in this
browser only, while the chat stays where you were reading and the pane
stays on Chat. A head
says what ran, with Back to Chat and Keep Terminal; the header's Chat,
Ctrl/Cmd+Shift+J and a
phone's Back return too, and Escape goes to the agent. On a desktop the
message box stays under
the terminal, dimmed; on a phone the key bar takes its place. Claude
Code's panels (`/config`,
`/permissions`, `/theme` and the like) can bring the chat back by
themselves when you close them,
once Claude records it; other agents' recorded screens do once their
input row is back, and the
  rest return by hand. A Ran in terminal row's
Open Terminal shows the terminal over the chat again. Busy commands stay
queued; only an
explicit Send now opens the terminal, never automatic delivery. Refused
sends keep their draft
and note. Watch-only devices never send or open it, and /resume still
opens Earlier sessions.
Commands the agent's own menu hides are not listed, but still go when
typed by hand.
  ([#1441](#1441))
- For an OpenCode pane whose skills are `@` attachments, the `@` menu
lists them under Skills
  before the files, and picking one inserts the skill's id.
  ([#1441](#1441))
- Growing OMP and Claude Code tasks now parse appended transcript
records incrementally, reducing
repeated work when long chats refresh while preserving tool results,
notices and history resets.
Live parser state shares Codex's bounded cache; earlier responses stay
unchanged as new records arrive.
([#1561](#1561) by
@Yoonwoo-Ha)
- The app is now called Ovis across the browser, install messages and
documentation, matching
the phone apps. Existing installs, settings, plugin identifiers and
update channels stay the same.
  ([#1454](#1454))
- A question card whose screen reads keep failing now says it may be out
of date ("Not updated: the
question on screen may have changed.") until a read answers again.
Answering stays safe: the
server reads the screen again first and refuses a changed question
(#1335).
([#1360](#1360) by @Noobear)
- The Earlier sessions dialog picks the agent from the same list as the
New tab and New worktree
dialogs, each agent with its icon and the chevron spaced as the app's
other controls, instead of
  a plain select whose arrow sat at the far edge.
  ([#1573](#1573))
- A finished agent opened in one browser is read in every browser of the
same server: opening it
on the phone clears its DONE dot on the desktop too, and the other way
around.
  ([#1463](#1463))
- Remove PC has a restrained red background and border before and after
its confirmation step,
retaining visible keyboard focus and the explicit second click to remove
the registration.
([#1394](#1394) by @snowykr)
- After a terminal command sent from Chat, Codex, omp, pi, gjc, OmO,
Hermes (classic CLI), Devin,
agy and Grok bring the chat back by themselves when you close the picker
or panel it opened,
once the agent's own empty input row is back on the screen. Only the
commands each agent was
recorded doing that for count (Codex's `/permissions`, omp's
`/settings`, Grok's `/resume` and
the like); print forms, toggles, editor handoffs, Codex's `/side` and
`/btw`, OpenCode and
  anything unrecorded still return by hand.
  ([#1637](#1637))

### Fixed
- The New session and History pickers show Hermes, Grok, Antigravity,
Devin and Command Code by
  their own names instead of their lowercase ids.
  ([#1543](#1543))
- The terminal attach process and its Node host no longer inherit the
server's `HERDR_WEB_TOKEN`
environment variable; they keep the socket path and the rest of their
environment.
  ([#1562](#1562))
- Choosing Jump to latest remembers bottom-follow before the virtual
list scroll completes.
Switching to Terminal immediately after that choice and returning to
Chat no longer restores
the older reading position. This fixes explicit Jump-to-latest intent,
not arbitrary upward
  restoration on long, active or reasoning-heavy tabs.
([#1346](#1346) by
@Yoonwoo-Ha)
- Remember bottom-follow without measuring rendered rows or looking up a
turn anchor; readers away
  from the end retain the existing paragraph-and-offset restoration.
([#1346](#1346) by
@Yoonwoo-Ha)
- Selecting and copying chat text now preserves the text as shown
instead of adding Markdown
syntax. Rich-text paste and the whole-answer MD and TXT copy actions
remain available.
  ([#1409](#1409))
- Chat no longer treats a command that leaves the agent waiting in a
screen Chat cannot show as an
ordinary send. Claude Code's `/usage`, `/cost`, `/status`, `/help`,
`/memory`, `/mcp` and
`/add-dir`, Codex's `/new` and `/fork` in a repository, `/cd`, `/usage`,
`/copy` and `/side`,
and the panels, pickers, confirmations and editors of omp, gjc, OmO,
Hermes, Devin,
Antigravity, OpenCode and Command Code are now Terminal commands: sent,
they open Terminal with
Back to Chat. A value typed with a picker command, such as `/fast off`
or `/export notes.md`,
  stays an ordinary send.
  ([#1596](#1596))
- A Claude Code skill or custom command named like a built-in command
(`/compact`, say) is listed
once in the composer's command menu, as the skill Claude runs, instead
of beside the built-in.
  ([#1441](#1441))
- Reconnects and unconfirmed sends can leave a bounded browser-side
diagnostic trail on this
server, without recording messages, credentials, addresses or terminal
output.
([#1357](#1357) by
@christi4nity)
- The chat and the session history now apply one rule to Codex rollouts:
a subagent's rollout (one
naming a parent thread or an agent role), an exec run's, or one whose
ids are null or contradict
its file name is no longer read as a pane's conversation or offered to
resume, while older
rollouts without those fields still are. A rollout whose first line is
longer than the chat or
  the history reads is left out instead of read unchecked.
  ([#1592](#1592))
- Two Codex panes in one folder whose answers are short each show their
own chat again with Codex
0.163, which starts a thread in the same second as its process; before,
both said the
  conversation was unavailable about as often as not.
([#1522](#1522) by
@jiaoew1991)
- A Codex pane with only short answers still finds its chat after
another pane in the same folder
runs `/new`: a thread that pane shows a long answer of under its first
prompt, is bound to, or
  that herdr reports for it no longer leaves this pane unsure.
([#1522](#1522) by
@jiaoew1991)
- Of two Codex panes in one folder with short answers, the one started
first finds its chat too
once the other shows its own first exchange, where it said the
conversation was unavailable.
([#1522](#1522) by
@jiaoew1991)
- On a phone, a composer notice's actions (such as the `/resume`
notice's Earlier sessions, Open
Terminal and Run in Terminal) wrap onto their own line, and its dismiss
button stays visible
  instead of being cut off at the edge.
  ([#1543](#1543))
- Wrapped and multiline message drafts are sized with an out-of-flow
measurement field instead of
collapsing the live input, preserving transcript spacing and the
paragraph being read (#1337).
([#1347](#1347) by
@Yoonwoo-Ha)
- The measurement field shares the live input's Korean, Japanese and
Chinese line-breaking rules,
including Korean placeholder wrapping, so localized drafts keep their
natural height.
([#1347](#1347) by
@Yoonwoo-Ha)
- Local Herdr timeouts, machine connection failures and recoveries, and
abnormal WebSocket closes
now leave timestamped, rate-limited diagnostic records without logging
input or credentials.
([#1356](#1356) by
@christi4nity)
- The browser connection trace no longer re-posts a batch the server
refuses with a 4xx status,
resumes reporting after you sign in again on the same page, and
malformed reports can no longer
  use up the server's shared report quota.
  ([#1423](#1423))
- Pairing a device, renaming or revoking one, and the web push key and
subscriptions are now
flushed to disk before they replace the previous file, so a crash or
power cut right after the
change is much less likely to bring back a revoked device or make every
phone subscribe to
alerts again. How much survives a power cut still depends on the disk
and filesystem honouring
  the flush; on Windows the folder itself is not flushed.
  ([#1568](#1568))
- File search and path lookup no longer run a repository's fsmonitor
hook, follow Git variables
the server was started with, or wait on a Git listing that never ends: a
listing past 16 MiB
  or 3 seconds, or one cut off mid-name, falls back to the folder walk.
  ([#1570](#1570))
- **Files → Changes** no longer runs a program named `false` found on
`PATH` with Git 2.35 or
older, and reads the repository asked about even when the server was
started with
  `GIT_COMMON_DIR` set.
  ([#1570](#1570))
- Keep sidebar status updates responsive after many completed turns by
caching read finishes and
bounding their in-memory history instead of repeatedly scanning browser
storage.
  ([#1536](#1536))
- A first message from New workspace or New tab no longer waits forever
when the agent started for
it quits before the message goes: it is held for Send now or Discard.
The same happens when an
agent of the same kind that the user starts later comes up instead, and
when the page that sent it
leaves the pane while it is being typed, so the pane's other queued
messages are not stuck behind it.
On native Windows the PC sees only the pane's shell, so it cannot tell
that the agent quit: there the
  message keeps waiting until you discard it.
  ([#1532](#1532))
- GJC Chat hides internal agent-to-agent IRC messages and automatic
replies, while keeping user
  messages that quote them visible.
  ([#1535](#1535))
- GJC questions using the Nerd Font selection cursor now show their
actual choices in chat
instead of only Up, Down, Enter and Esc controls. Moving the cursor
preserves the question's
  identity and uses the current selection when answering.
([#1553](#1553) by
@Kinetic27)
- GJC chats on a busy machine give cold session lookups up to five
seconds per command and
ten seconds overall instead of timing out after two seconds per command.
Session snapshots
  retain the shorter status lookup budget; failed status lookups
  are held for 30 seconds without preventing chat reads from retrying.
([#1364](#1364) by @sskys18)
- GJC chat and status reuse their verified session binding when other
sessions write heartbeats,
instead of restarting the SDK lookup for every pane. Session changes
still require SDK validation.
  ([#1343](#1343))
- Grok keeps Chat with older sessions open and uses Terminal when the
session is uncertain.
([#1352](#1352) by
@infowolfe)
- One failed health check no longer shows herdr offline or switches a
Windows PC's panes to the
terminal lens: the header says Status unknown with the last herdr it
saw, and herdr unavailable only
  after a second failure in a row.
  ([#1581](#1581))
- A malformed, oversized or misaddressed answer from herdr now fails
only the request it answers,
with a clear error, instead of hanging until the timeout, growing the
server's memory or being
taken as another request's answer; event subscriptions report such a
frame and close.
  ([#1584](#1584))
- Hermes `/status` sent from Chat now shows its result card on the first
send in a new pane too, even
when the computer is busy. A send whose result was missed no longer
leaves every later `/status` in
that pane without a card for ten minutes. The same holds when another
device has the terminal
  scrolled up.
  ([#1543](#1543))
- Sending Hermes `/status` (or another informational command) from Chat
again now shows that send's
own result card each time, instead of "Runs in the terminal" once
earlier identical results fill
  the terminal.
  ([#1543](#1543))
- Slow API requests can return their result or timeout error instead of
losing the HTTP connection
  while bounded Herdr calls are still running.
([#1355](#1355) by
@christi4nity)
- The app can be installed behind a reverse proxy that signs in every
request (Authelia,
oauth2-proxy and the like): the browser now sends its cookies with the
manifest request.
([#1332](#1332) by
@ascandroli)
- Mouse wheel and phone swipes scroll terminal history on Windows and
other mirrored panes;
  read-only connections still only pan their local grid.
([#1446](#1446) by
@Davesaggio)
- A Codex started in a terminal shows its model and reasoning level
before the first message,
  from Codex's live footer, while the chat shows the terminal output.
([#1374](#1374) by
@evanwy0223)
- Before the first message, a model switched in the terminal shows in
the message box once the
supported agent draws it. omp still waits for its transcript to record
the model; the bridge
never runs `omp models`, which can refresh the CLI's OAuth credentials.
([#1374](#1374) by
@evanwy0223)
- A pane that runs OmO is now treated as OmO by the composer even while
herdr labels it Claude
(OmO's Claude child is running): sending a message no longer stops on a
Claude input-box draft
  refusal or tries to clear a Claude draft there.
  ([#1441](#1441))
- A multi-line message sent to an OmO pane that herdr has no agent label
for is now pasted as one
bracketed paste instead of line by line, so its first line is no longer
sent alone.
  ([#1441](#1441))
- An OmO pick list (an extension's select, such as the init-deep
advisor's "Run now / Skip this
time / Never…") shows in the chat as a card with its own options again,
instead of a "Waiting for
input" card offering only ↑, ↓, Enter and Esc. A pick list that counts
down in its title keeps
the same card while it ticks, so an answer tapped a second later is not
refused as stale.
([#1495](#1495) by
@nahwan-kim)
- An omp pane started with an absolute `--cwd` shows its chat when herdr
names no session file
and the directory herdr reports is not omp's own, such as the shell's or
a symlink's real path:
the session is still looked up in the directory herdr reports first,
then under that `--cwd`.
  ([#1594](#1594))
- A message or command sent from the chat to an omp that is still
starting no longer stays typed
in its input box: omp shows the box before it takes an Enter, so the
send waits until herdr's omp
integration reports the session (omp does so once it takes input), for
an omp started moments ago.
  ([#1475](#1475))
- A new OpenCode 2 pane offers your project and user skills as `@`
attachments before its first
session starts, using the OpenCode version the PC's install reports,
instead of listing them as
OpenCode 1 `/` commands. Once the pane has a session, that session's
version decides as before.
  ([#1543](#1543))
- Native question answers stay bound to the current pane, session and
form. Local service discovery
rejects stale or non-loopback endpoints, bypasses environment proxies,
and bounds slow requests.
([#1257](#1257) by
@bardiz12)
- Polling does not invalidate an unchanged question or turn an
acknowledged answer into an error.
A temporary service outage keeps an already displayed native card and
its unsent edits.
([#1257](#1257) by
@bardiz12)
- Back and question tabs preserve unsent edits, and multiselect
submissions include both checks
and custom text. Abandoned drafts are bounded and expire after 30
minutes.
([#1257](#1257) by
@bardiz12)
- OpenCode question cards keep edits and allow immediate retries after a
failed reply, and optional
questions can be skipped. Unrelated service metadata no longer resets a
form's progress.
  ([#1421](#1421))
- Answers sent from the message box show the translated warning when
OpenCode has not confirmed
delivery. Native service connections accept only the loopback addresses
127.0.0.1 and [::1].
  ([#1421](#1421))
- Subscription usage reads OpenCode 2's own credential store before the
`auth.json` OpenCode 1
wrote. OpenCode 2 keeps its provider sign-ins in `opencode.db` and
leaves that file standing with
the key it has since replaced, so the OpenCode card reported "Sign-in
expired" for a CLI that was
signed in and working. The store's active key answers first, and a store
without one (signed out of
OpenCode 2) shows no card; the file still answers beside OpenCode 1's
store, or with none.
([#1329](#1329) by
@krish-kant)
- `GET /api/pane/read` takes `lines` only as plain decimal digits from 0
to 4294967295 and refuses
any other value (blank, signed, fractional, exponent or too large) with
400 `invalid_lines`
instead of passing it to herdr; a blank value is no longer read as zero.
Every count herdr
  takes still goes through unchanged.
  ([#1571](#1571))
- A pasted or dropped PNG, JPEG, GIF or WebP image is saved with the
extension of what its bytes
are, not the one its file name suggests, and a file that only claims to
be one of those images
is refused with its reason instead of being saved for the agent to read.
  ([#1599](#1599))
- The phone header's Chat/Terminal switch keeps clear of the bar's top
and bottom edges in both
densities: its options take the density's segmented height, so its track
is 34px tall in the 52px bar
and 32px in the compact density's 46px bar, which it used to nearly
touch.
([#1519](#1519) by
@adnankassem)
- On a phone, the header's Chat/Terminal switch centers its icons and no
longer touches the header's
bottom rule (in compact density it was as tall as the bar). The buttons
still take a full
  44 px tap.
([#1367](#1367) by @Noobear)
- A pi chat now shows its context ring for models pi lists in its
commandcode cache or model
  store, not only for providers defined in `models.json`.
([#1391](#1391) by
@diegolhambi)
- Model and effort pickers no longer confirm a stale choice when the
agent stops waiting for the
  answer during the final screen read.
  ([#1435](#1435))
- A Portal that stops on its own after its address was up is started
again once, on the same relay
and address, and Settings → Phone & devices says Recovering… meanwhile;
a second stop shows the
error with Portal's output instead of leaving the address down without a
word or restarting it
  again.
  ([#1587](#1587))
- When the server cannot save a shared setting or pin, Settings now says
the change is not on the
server yet, that reloading or closing the page can undo it, and offers
Retry. After three failed
saves in a row the browser resends less often (after a minute, then up
to every five minutes)
until you press Retry or the connection reopens, and edits made
meanwhile are kept. A late resend
of a refused change no longer overwrites a newer value another device
saved meanwhile, while a
setting you pick again after the refusal still wins. While the
connection is lost it waits for it
to come back instead of resending, and a connection the browser gives up
on (for example a proxy
error while the server restarts) is opened again, so alerts and other
devices' changes no longer
  stop arriving until a reload.
  ([#1595](#1595))
- A damaged or unreadable shared preferences or read-finish file is no
longer lost to the next
change. Reading never touches it; the first change moves the damaged
file, byte for byte, to
`preferences.json.bad` or `seen.json.bad` (private to you, the latest
damaged copy only), a file
repaired by hand while the server runs is kept with the change added to
it, and a file that
cannot be read or set aside is not written over, so the change fails
instead.
  ([#1564](#1564))
- A server or remote bridge that crashed no longer blocks its restart
when its old process number
now belongs to another program: startup locks and the bridge registry
record the owner's start
  identity, and that other program is never signalled.
  ([#1567](#1567))
- Attaching to a terminal once again waits for input to be ready before
signalling completion,
preserving queued keys, clicks and text and the order of Stop followed
by a message.
  ([#1342](#1342))
- Opening a finished agent's terminal while its connection to herdr is
being restored no longer
clears its DONE dot from the screen left over from before: it clears
once the terminal shows
  current output.
  ([#1472](#1472))
- An oversized or unreadable answer from another PC's bridge is now
refused at a fixed size
instead of being held whole in memory: connecting, refreshing and the PC
proxy stop reading it,
report a short error in the user's language that repeats none of it, and
a watching device
  never gets a prompt that could not be redacted.
  ([#1588](#1588))
- Opening a pane in another tab or on a phone, or reconnecting, no
longer copies again to the
clipboard what a program in the pane copied before; its new copies still
reach the clipboard.
  ([#1600](#1600))
- Update and restart, and the header's Update, install exactly the
release they offered: a release
published in the meantime installs nothing and is shown to be checked
first, and a server whose
supervisor cannot install by revision asks for a restart instead of
installing.
  ([#1590](#1590))
- In macOS Safari, Backspace in a terminal no longer skips a press after
deleting the last letter of
a Korean syllable: 한 then four Backspaces now also deletes the character
before it.
  ([#1363](#1363))
- Chat shows only the current agent session's command results: after an
agent restarts in the same
pane, the earlier session's commands no longer appear. A `/clear`,
`/new` or resume sent from Chat
keeps its own row in the conversation it starts, without claiming that
it finished. Commands sent
before an agent's first reply stay with that agent while it keeps
running, also through a moment
in the background (Ctrl+Z on Linux and macOS); once a different agent
takes over the pane, they
are hidden, even if Chat was not open when it happened. A command sent
to a restarted agent while
the pane still shows the previous session stays once the agent's own
session appears within a
minute, unless Chat started another session after it. Within that
minute, a session change typed
in the terminal of an agent that resumed the same session can still keep
such a command. Where
Chat cannot find the agent's program at all (native Windows, or an agent
started under another
program name), such a command stays with the session that the same agent
starts in the same
terminal; a later session, another agent or terminal still hides it.
Outside Linux, an agent
restarted under the same process number cannot be told apart from the
one before it.
  ([#1543](#1543))
- SSH PC management controls now stay within narrow sidebars: the rename
field and action buttons
  reflow in place, and long labels wrap without clipping.
([#1392](#1392) by @snowykr)
- Opening a finished pane clears its DONE dot only after its answer or
terminal output is
actually visible. Covered panes, loading or failed chats, and terminal
reconnections keep
  unread finishes marked.
  ([#1342](#1342))
- Reading older chat keeps the finish unread. Jumping to the latest
answer clears it only
after the jump arrives; small scrolls above the end show the way back.
Resizing and restoring
  a short chat work without an extra scroll.
  ([#1342](#1342))
- An older answer cannot clear a newer finish. Agents whose chat cannot
prove completion keep
the dot conservatively; opening their Terminal view can acknowledge the
output.
  ([#1342](#1342))
- Read finishes stay read across pane switches and browser tabs on the
same device. Every
web-server restart or update brings read DONE dots back; read records
are not carried across
  server restarts.
  ([#1342](#1342))
- The sidebar's PC control buttons are the standard control height
again, Rename shares the name
field's row in a wide sidebar, Remove PC dims like its neighbours while
a rename or disconnect
runs, and danger buttons keep their red tint on hover everywhere in the
app.
  ([#1422](#1422))
- Documents opened through copied read links keep their own scroll area
at desktop widths,
rather than expanding beyond the window and leaving scrolling to the
page.
([#1586](#1586) by
@Kinetic27)
- A Markdown table whose separator has a one- or two-dash cell
(`|---|:-:|`) shows as a table in the
  chat, as on GitHub, instead of as its pipe-separated source.
([#1361](#1361) by @Noobear)
- Going back to the chat while a terminal command's screen is still open
(Claude Code's `/btw`
answer, a picker left up) no longer lets the next message from the
message box be typed into
that screen and do nothing, for Claude Code and the agents above (not
OpenCode): the composer
says the command is still open in the terminal, with Show terminal, and
Send (or a queued
message's Send now) keeps the message until the screen closes or you
choose Send anyway.
  ([#1637](#1637))
- Opening the app no longer flashes the dark amber default before your
saved theme: the saved light,
dark or single-mode theme (Dracula on the light side stays dark),
including System and older saved
palettes, is drawn from the first frame, and the installed app's title
bar color matches it at once.
  ([#1569](#1569))
- Settings → Updates no longer tells you to switch to main when the
server was started from an
installed update's folder instead of its source checkout: it now says to
restart the app from
  the source checkout, which is what lets updates run again.
  ([#1417](#1417))
- Typing or composing text in a wide mirrored terminal no longer pulls
the view sideways.
Windows terminal wheel panning stays in place when output arrives, and
tapping the terminal
  without scrolling no longer changes shared history.
  ([#1534](#1534))
- Loading the page no longer sends about 33 requests per workspace
folder to find its project icon:
each folder is asked once (`GET /api/fs/favicon`), and a folder without
an icon is an answer, not
a 404. A reverse proxy with a rate limit no longer answers 429 to the
burst, and the browser
console no longer fills with red 404 lines on every load. A 429 is no
longer remembered as "no
  icon" either: the folder is asked again when its row next appears.
  ([#1339](#1339))
- A dragged workspace order no longer jumps back while its moves are
still landing: a roster read
before the move, a cached roster or another PC's update cannot undo it,
and the first roster
read after the move (another browser's later order included) replaces
it. A remote PC does this
once its bridge is updated to the next release; until then it keeps the
earlier behaviour.
  ([#1593](#1593))

### Maintenance
- Composer geometry regressions freeze the demo conversation while
keeping it idle, so turn
completion cannot change the transcript during measurements on phone and
desktop.
([#1347](#1347) by
@Yoonwoo-Ha)
- Settings and PWA draft checks target the visible input explicitly;
locale regressions cover
  native draft and placeholder heights on phone and desktop.
