Change

Claude Code records a message that another session sends into a pane (origin.kind: "peer") in two ways. Between turns it is a meta user entry, and mid-turn it is a queued_command attachment. The chat reader skipped both. So the work such a message started was appended to the assistant's previous answer, and the message itself never showed.

Both are now read as a folded notice, Message from {name}, that opens its own user turn. This works in the newest page and in older pages. The new string is in the ko, ja, zh and tr dictionaries.

Validation

  • server/conversation.test.ts: new cases for a peer message between turns and mid-turn (queued attachment), and across a page boundary.
  • bun run generate:types --check, bun run typecheck, bun run build: pass.
  • bun run test:unit on Windows: the same 199 failures as main, no new ones; the two new cases and the i18n dictionary tests pass. On this machine main itself fails the same set.
  • This has been running as a local patch on recent 0.4.x releases, up to 0.4.8.

Thank you for taking a look. If you would prefer a different label for the notice, or a different place for it in the chat, I am glad to change it.

Cross-session messages are recorded as meta user entries (between turns) or
queued_command attachments (mid-turn) with origin.kind "peer". The reader
skipped both, so the work such a message started was appended to the answer
before it. Show them as a folded notice ("Message from <session>") that opens
a turn, in pages too.

Layer / File(s) Summary
Parse and page peer notices
server/transcript-records.ts, server/conversation.ts, server/conversation.test.ts
The parser recognizes peer-origin messages in meta user entries and queued-command attachments, emits notice turns, and treats them as paging boundaries. Tests cover chronological notice turns and complete, non-overlapping pages.
Display peer sender labels
src/components/ChatView.tsx, src/lib/i18n.*.ts, CHANGELOG.md
Chat labels peer notices as “Message from {name}.” Japanese, Korean, Turkish, and Simplified Chinese translations and a changelog entry were added.

Reviewed edba3e2: no blocking regression found in the peer-message parsing/rendering change. Both meta-user and queued attachment forms are handled, with pagination coverage for meta-user records.

Verified on an isolated archive of this exact head: server/conversation.test.ts 100 passed; src/lib/i18n.test.ts 20 passed. Existing installed dependencies were reused; full/browser/native-Windows checks were not rerun.

Conditional merge recommendation, not an assertion that merge gates are satisfied: address/resolve the existing queued-attachment pagination discussion (discussion_r4245249256), retain contributor credit in the changelog, and obtain the three required checks on the final head. The attachment page-boundary limitation also affects existing human queued prompts; do not dismiss the thread without documenting the decision. No supersession/closure reason found.

… told once

Review follow-ups on devswha#870 (Codex astra medium, 2026-10-12):

- The page-boundary scan admitted only `"user"` lines, so a peer message
  Claude recorded as a queued attachment (mid-turn) was no boundary while the
  parser made it a turn; a page starting after it would open mid-turn. Lines
  carrying `"kind":"peer"` are candidates now, and `opensTurn` takes both
  forms. A peer message is never a re-send of this session's prompt: it opens
  a turn without touching the prompt chain, so the human re-send rule sees
  only its own prompts.
- Claude can record one delivery twice (queued, then echoed as a meta entry);
  the parser now keeps one notice per sender and message id (`claudePeerId`),
  the first position winning.
- Wording: "Message from another session: {name}", and "Message from another
  session" for a sender without a name (the source is then a bare `peer:`),
  in all four dictionaries; the CHANGELOG line follows.
- Tests: distinct message ids per delivery, the echoed delivery and the
  unnamed sender, and pagination over both record forms. The 16 MiB window
  case itself stays untested; the boundary fix is what makes it right.

Merge-session review (Codex astra medium, 2026-10-12) on top of the earlier read-only review; follow-ups pushed as 656a3c9:

  • Queued form bounds a page too. The page-boundary scan admitted only "user" lines, so a peer message Claude recorded as a queued attachment was a turn for the parser but no boundary for the paginator. Lines carrying "kind":"peer" are candidates now and opensTurn takes both forms. A peer message is never a re-send of this session's prompt: it opens a turn without touching the prompt chain, so the human re-send rule sees only its own prompts.
  • One notice per delivery. Claude can record one delivery twice (queued mid-turn, then echoed as a meta entry); the parser keeps one notice per sender and message id, the first position winning.
  • Wording. "Message from another session: {name}", and "Message from another session" for a sender without a name, in all four dictionaries; the CHANGELOG line follows and keeps your credit.
  • Tests: distinct message ids per delivery, the echoed delivery, the unnamed sender, pagination over both record forms. The 16 MiB window case itself is not unit-tested; the boundary fix is what makes it right.

Verified locally: typecheck, build, unit tests (conversation 102, i18n 20). Merging once the fork CI run finishes. Thanks for catching this one, it was an easy transcript to misread.

## Change

Release 0.4.9 from main at 6e575a8 (v0.4.8 + 193 commits), plus one
blocker fix found in pre-release QA.

- **`fix(terminal)` (ededf39)**: an open terminal re-attaches by itself
after herdr restarts or updates. Before, the pane kept "terminal ended"
and dropped typed input until another pane was picked (also in v0.4.8).
The renderer now keys its attachment on the pane's `terminal_id`, which
herdr changes on restore, and a cached tab waits until it is shown
again. Locked by `scripts/herdr-restart-regression.ts` (fails on main,
passes here), added to the browser lane.
- `package.json` and `herdr-plugin.toml`: 0.4.9.
- CHANGELOG: `[Unreleased]` and 147 changelog.d fragments become
`[0.4.9] - 2026-10-16`, with `by @login` for outside contributors (22
PRs) and #1164 by @aisensiy carried in #1169. The reattach entry has no
PR link yet: it is this PR's.
- `release-summaries.json`: 0.4.9 in en/ko/ja/zh (7 new, 7 improved, 8
fixed in each).
- `REMOTE_BUNDLE_VERSION` 27 -> 28: the bundle's inputs changed since
remote-v27.
- `telemetry/deployed.json`: the Worker was redeployed (version
431d6e07) for the settings schema changes since v0.4.8 (#1120, #1123,
#1135); before it, this build's install event got HTTP 400.

## Release notes (as installs will show them)

### New features

- New workspace → Browse makes a new folder and starts in it.
- Shortcuts record chords with their exact modifiers; New tab and splits
can be bound.
- Pin workspaces, worktrees and agents from a row's menu or a
right-click.
- A Jump to bottom button returns a terminal scrolled up into history to
the live end.
- Pick a skill anywhere in a message, not only at its start.
- Connect to remote PCs from a Windows PC.
- Mod+Shift+E puts the cursor in the pane's input.

### Improvements

- Split view halves are independent, and both may show the same tab.
- Phones start in direct typing; the key bar's keyboard key lights for
the input line.
- Claude's whole plan shows from its plan file, and its answer review
reads correctly.
- Send shows progress until the agent takes the message, and Stop always
goes first.
- Recent tabs stay ready, so switching back shows the chat at once.
- Sign out moved into Settings behind a confirm; menus and settings were
trimmed.
- A workspace or tab reopens on the pane you last saw, also after a
reload.

### Bug fixes

- Open terminals reconnect by themselves after herdr restarts or
updates.
- With herdr 0.9.4 or later, a second device no longer types stray
characters into a pane.
- Typing Hangul from an iPad hardware keyboard composes syllables.
- Opening an Android keyboard no longer resizes the shared terminal.
- When the app's folder is replaced under it, it asks for a restart, not
an endless reload.
- Hermes: Stop ends a running turn, and Chat will not send over text
typed in its input.
- The sidebar no longer breaks on a worktree without a branch.
- A click on a lone pane's top right corner reaches the program there.

The full changelog is the [`[0.4.9]` section of CHANGELOG.md on this
branch](https://github.com/devswha/herdr-web-ui/blob/chore/release-0.4.9/CHANGELOG.md)
(too long for a PR body).

## Verification

Scenarios ran on c5f297e. The two commits after it (a978847, 14387e5)
change only CHANGELOG.md, from the gate review: links for #863, #864,
#869, #870, #972 and #1161, #811 moved from 0.4.7 (where a merge put it)
into 0.4.9, and entries no longer name the removed Files at once setting
or Find. No runtime behaviour differs from what was verified.

QA plan with scenarios and pass conditions: user flows install → first
run → daily use → errors, on Linux, macOS, Windows and remote PCs. Each
scenario ran twice: a first pass on main 6e575a8, then an independent
re-run by separate agents on this head (c5f297e), checked artifact by
artifact. Browser checks drove a real Chrome at 1440 px and 390 px
(iPhone emulation), light and dark. Local herdr was 0.9.5 (CI pins
0.9.3), so this also covers the newer herdr users have.

| ID | Flow | Where | Result on c5f297e |
|---|---|---|---|
| L1 | Fresh install: README plugin path and `install.sh` one-liner |
Clean Ubuntu 24.04 (Docker) | PASS: both exit 0, health ok, startup hook
after a herdr restart |
| M1 | Plugin install, start, first terminal | MacBook, macOS 26.6,
herdr 0.9.5 | PASS: installed in ~1 min, health ok, `echo` runs |
| W1(a) | Fresh native install | windows-latest ("Real Windows install"
check) | PASS (CI) |
| W1(b) | Plugin install on an existing herdr 0.9.3, mirrored pane |
Windows 11 PC | PASS; installer unit test PASS |
| L2 | First run: workspace list, new workspace, type in a pane | Linux,
herdr 0.9.5 | PASS |
| L3 | Daily use: split halves on one tab, Browse → New folder, pin,
record a shortcut, Sign out confirm, phone direct typing and input-line
key | Linux | PASS 7/7 |
| L4 | herdr down, server restart, typing while disconnected (kept as a
draft), token-protected server refuses a fresh browser | Linux | PASS |
| FIX1 | herdr stop + start with a pane open: re-attaches without
re-pick or reload | Linux | PASS (screenshots below) |
| R1 | Remote PC over SSH: bundle smoke, key + password logins, desktop
and phone | Linux sshd, Debian container | PASS |
| L5 | In-place update and PWA update | Linux | PASS for the product;
`update-browser-qa.ts` needs a fixture body after a fold (#1178) |
| C1 | Integration suite on herdr 0.9.5 + settings/split/shortcut/chat
browser scripts | Linux | 521 pass / 0 fail; `chat-browser-qa.ts` script
drift (#1178) |
| T1 | 1,484/2,000-char one-line messages into real Claude Code | Linux;
macOS | Linux PASS; **macOS input line: known issue #1174, see below** |

CI on this head: Fast checks, Integration and browser, Native Windows
install, Real Windows install, macOS session identity and the remote
bundle builds all pass. Local `bun run check fast`: 3,825 unit tests
pass; `bun scripts/release-guards.ts` passes.

### Known issue shipped: #1174 (not a regression)

On macOS, a single-line message of about 1.5 KB sent through the
terminal **input line** can reach Claude Code without its first 1,022
characters (5/5 in the re-run; the first pass kept it whole). It
predates 0.4.8. Two fixes were built and rejected on runtime evidence:
bracketed paste over `pane.send_text` corrupts plain shells, and sending
through the attach stream lets a following Stop overtake the message. A
safe fix needs a program-aware paste RPC from herdr or a shared delivery
barrier. Direct typing, which phones start in from this release, and the
desktop terminal delivered the same messages whole. Details in #1174.
**Shipping with it is the maintainer's call at merge**: the QA plan
counted it as a blocker, and no safe fix exists in this release.

### Follow-ups filed
#1177 (Homebrew Bun hint), #1178 (three QA scripts outside CI drifted),
#1179 (small UI findings).

Screenshots live on the `qa/v0.4.9-evidence` branch (not for merging;
delete it after this release).

## Release

After this merges and its CI on `main` passes: push `remote-v28` on the
merged commit, wait for the Remote PC bundles workflow, then run the
Release workflow with `0.4.9`. None of that was done here.
