Why

Several modules build sentences in main and send them to the window, and main has its own menu and native dialogs. Main had no catalog, so a translated window would still show those in English. This is the first batch of #622, and #625, #627, #628 and #629 need it.

What changes

  • Main resolves the locale once (localeReply() in src/main.js) and applies it with the same applyLocale() the renderer uses, before it builds the menu and the window. The i18n:locale handler returns that same reply, so main and the window cannot disagree, and the en-XA pseudo-locale now covers main too.
  • Wrapped: "Open App Log" and "Show Logs Folder" in the Help menu, and the titles and filter names of the save-patch, choose-patch and choose-application dialogs. 10 strings.
  • Electron's role menus (File, Edit, View, Window) are deliberately left alone, as the issue says.

How to test this

Covered by a journey, red without this change: from the repository root, npx playwright test --project=journeys tests/e2e/journeys/i18n.spec.js -g "Help menu". It reads the Help menu labels and the title and filters the patch file dialog was opened with, under --lang=en-XA.

What the journey cannot reach is the real OS dialog. Platform: Windows for the dialogs (macOS does not show an open or save panel's title), either for the menu. Build: the current head.

Starting state: the app launched from the repository root with npx electron . --lang=en-XA, with one site that has an edited file.

  1. Open the Help menu. Expected: both "Open App Log" and "Show Logs Folder" are accented and in brackets. "Toggle Developer Tools" stays in English (a role menu).
  2. Click Review & submit changes, then Save. Expected: the save dialog's title ("Save Diff File") and its "Patch Files" filter are accented and in brackets.
  3. Cancel. In the Apply a patch or PR card, open the Diff tab and click Choose a .diff or .patch file…. Expected: the dialog title and both filters are accented and in brackets.
  4. Cancel. Open Site actions → Open in → Other application…. Expected: the title and the "Programs" filter are accented and in brackets.

What must not have happened: launching with no --lang shows every one of these in English, and the app opens one window, not two, when started from a wpct://ticket/… link.

Risks and limitations

  • Main now awaits the locale before it creates the window, so startup gains one catalog read (the same one the window already waited for). A wpct:// link that arrives in that gap opens the window itself; startup then creates a window only if none exists.
  • Not tested by a journey: the save dialog and the choose-application dialog. Only the patch file dialog is checked.
  • "Dev server stopped unexpectedly (see Help → Open App Log for details)" still names the menu entry in English. It belongs in Translate the Terminal and Logs output #627, where it should take the label as %s.

Fixes #623. Part of #622. Follows #632 (#584).


Design decisions and alternatives considered

The reply is memoised rather than computed twice so the window and main read the catalog once and always agree. applyLocale() was reused as is: it has no DOM dependency, and with main's setLocaleData and addFilter it installs the pseudo-locale filters for main too. Main's CommonJS @wordpress/i18n builds its default instance on @wordpress/hooks' defaultHooks, and there is one copy of @wordpress/hooks, so the filters apply to menu.js as well.

Review outcome (required, see AGENTS.md)
  • Review: completed. Reviewer: a separate agent context (Claude Code, read-only) against .github/instructions/code-review.instructions.md; head 08d29ef / base eb3f70f. npm run lint clean, npm test 1955 pass / 0 fail, full journey suite 114 pass. Outcome: 1 [fix here] · 1 [follow-up], both 🔵 low.
    • Architecture, src/main.js ready path: if the locale load rejected, startup would stop before the menu and the window. Not changed: the reviewer found no path that rejects (resolveCatalog catches its own read and parse errors), and AGENTS.md asks for no defensive branches without a realistic path.
    • Tests, tests/unit/ipc-wiring.test.cjs: the ready path runs after the harness removes its require hook, so a lazy require added there would load real modules. Fixed with a note beside the option.
  • Since review: 08d29ef → 4c34787 checked; the only change is that comment. Then rebased onto trunk after Load translations for the OS language, not only the languages Chromium ships #632's squash merge: head a6fb7da / base 8dbed36. The diff against the new base is line for line the reviewed one plus that comment; lint clean, npm test 1955 pass / 0 fail, journeys 114 pass on the new head.
Implementation notes
  • tests/unit/ipc-wiring.test.cjs gains a ready option so one test can run the ready path. It checks that main applies the locale before any menu or window exists, that the handler returns the same reply object, and that the catalog is read once.
  • tests/unit/menu.test.cjs checks the labels are translated when the template is built, not at require time.
Screenshots or recording

Nothing changes in English. In the pseudo-locale the change is the Help menu labels and the native dialog titles, which the journey asserts.

📝 Walkthrough

Walkthrough

Startup now resolves locale data once and applies it before building the menu or creating a window. The Help menu labels and three native dialog titles and filter names use translated strings. Unit and end-to-end tests check locale reuse, startup ordering, and pseudo-localized menu and dialog text.

Assessment against linked issues

Objective Addressed Explanation
Load and apply the translation catalog in main, reuse the locale reply, and translate the specified menu labels and native dialog text [#623] ✅

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to a6fb7

If a deep link arrives during the brief startup wait, the window may open before the locale is applied. This is a narrow timing edge case and the fix is small. The rest of the change looks safe to merge.

Security Architecture Review

Security architecture risk: 🔵 Low · up to a6fb7

The changes are bounded to localization and startup sequencing. Existing file-selection behavior and deep-link safeguards are preserved. No new security attack path was identified, but exceptional startup failure and recovery behavior is not fully established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • observed — Catalog application now occurs in the Electron main process, increasing the importance of the application-local catalog trust boundary. The changed consumers affect menu and native-dialog presentation; the inspected changes do not grant translated strings authority over file paths, accepted extensions or action handlers.

Trust Boundaries and Controls

  • observed — The locale IPC handler supplies no caller-controlled locale or catalog path to the resolver. Selection originates from command-line or system settings and is matched against canonicalized names enumerated within a fixed application-local directory, rather than treating the requested locale as a filesystem path.

Resilience and Maintainability Implications

  • inferred — An unexpected rejection outside the resolver's handled catalog failures would remain cached and prevent the awaiting startup continuation from completing. No production trigger for such a rejection was established. The deep-link queue preserves pending tickets across resets, but final delivery through a packaged renderer remains unproven because the inspection found no source invocation of the exposed readiness API.

Architecture 🔵 low [fix here]: Defer deep-link window creation until locale setup finishes.

An accepted wpct:// link can create and load the main window while localeReply() is pending, before applyLocale() runs. The menu is built afterward, but this bypasses the stated locale-before-window order. Keep the ticket queued and defer opening the window until locale application is complete.

## Why

The Review & submit dialog was still plain English in a translated app.
This is the #624 batch of #622.

## What changes

- **The diff pane stops reading English to decide what it holds.** Main
returned the literal `'No changes.'` and failures were prefixed
`'Error'`, and the dialog compared against both. Main now returns an
empty patch, a failed load sets `patchLoadFailed` with the raw error,
and the pane says "No changes." or "Error: %s" in the contributor's
language.
- **Wrapped:** the dialog, its diff pane, the Trac and mentor
destinations, and the sentences they take from `changes-note.cjs`
(`patchReviewContext`, `discardDisabledReason`), `pr-checkout.cjs`
(`prSubmissionRefusal`, `prSubmissionBlocked`), `wporg-handle.cjs` and
`patch-provenance.cjs`.
- **Rewritten, not just wrapped:** "N days old" uses `_n`; "Save, then
open #N" and "Save patch as %s" use `sprintf`; the heading is one
sentence per kind (ticket, issue); `<strong>Save</strong>`, the event
name and the applied patch's name go through `createInterpolateElement`.
User text (an event name, a patch's file name) goes in as an element,
never into the string, so a `<` in it stays text.
- **An English fix on the way:** with no name on record, the refusal
used to read "Revert The patch you applied before…". Each sentence now
has a version without a name.
- `@wordpress/element` is now a direct dependency (a one-line lockfile
change; it was already installed through `@wordpress/components`).
- Deliberately not here: the pull request card (#625), the Copy button's
labels (#630), and the changes note and pull request checkout sentences
(#628, #629).

## How to test this

Covered by journeys in `tests/e2e/journeys/i18n.spec.js`, all red
without this change. From the repository root: `npx playwright test
--project=journeys tests/e2e/journeys/i18n.spec.js -g "Review &
submit|nothing to send|mentor card"`. They open the dialog in the en-XA
pseudo-locale with an old trunk, with no ticket and with one, with
nothing to send, with a remembered username and event, over someone
else's pull request, and over an applied patch with and without a name,
and fail on any visible English.

To look at it by hand, on either platform, on the current head: run `npx
electron . --lang=en-XA` from the repository root, open a site with an
edited file and click the pseudo-localised **Review & submit changes**.

**Expected:** every string in the dialog is accented and in brackets
except the pull request card, the Copy button, file paths and the diff
itself.

**What must not have happened:** in English, the dialog reads exactly as
before, apart from "Generating patch..." becoming "Generating patch…". A
tree with nothing to send still shows "No changes." and offers no
destinations, and a diff that fails to load still says so instead of
claiming there are no changes (`pr-checkout.spec.js` covers that one).

Not covered: the invalid-username error. It is built in main, which has
no catalog until #634 lands, so its journey step is left for after that.

## Risks and limitations

- Review: 1 [fix here] · 3 [follow-up], all low. The fix is in; the
three follow-ups are below.
- Saving or copying with nothing to send now writes a 0-byte file and
empties the clipboard; before, both carried the text "No changes.". The
buttons were already enabled in that state. Follow-up: disable them when
there is no diff.

<details>
<summary>Design decisions and alternatives considered</summary>

The journey's scanner (`unwrapped`) now treats a text node as translated
when the element around it, past bold, italic or code, holds one
bracketed string from first character to last. A sentence with a link or
a bold word in it is several text nodes, and only the whole is
bracketed. "[Foo] English [Bar]" still fails, so English spliced between
two wrapped strings is still caught. Sentences that sit side by side in
one notice each got their own `<span>` so the rule can see where one
ends.

`'(<discard />)'` is a translatable string of punctuation: some
languages write brackets differently.

<summary>Review outcome (required, see AGENTS.md)</summary>

- **Review:** completed. Reviewer: a separate agent context (Claude
Code, read-only) against
`.github/instructions/code-review.instructions.md`; head `90ae783` /
base `8dbed36`. `npm run lint` clean, `npm test` 1954 pass / 0 fail,
journeys 115 pass. Outcome: 1 [fix here] · 3 [follow-up], all 🔵.
- Tests [fix here]: the journeys missed the remembered mentor card, the
empty diff and the applied-patch warning. **Fixed** in `529b7ae`;
reaching them also showed the applied patch's headline shared an element
with the next sentence, now its own `<span>`.
- Architecture [follow-up]: `loadError` in `patch-diff-pane.jsx` and the
applied-patch headline in `review-dialog.jsx` pick a string inside
`.jsx`, where the unit suite cannot reach them. **Deferred:** both are
two-way choices now covered by journeys.
- Behaviour [follow-up]: Save and Copy with nothing to send (above).
**Deferred:** the buttons were enabled in that state before this PR.
- Tests [follow-up]: the invalid-username step of the issue's journey.
**Deferred** until #634 lands.
- **Since review:** `90ae783 → 529b7ae` checked; the change is the
journeys and the one `<span>`. Lint clean, `npm test` 1954 pass,
journeys 119 pass on the new head.

<details>
<summary>Implementation notes</summary>

- `tests/e2e/helpers/git-site.cjs` gains a `trunkDate` option on
`makeSite`: the app reads a site's age from its trunk commit, not from
its record.
- `NOT_A_HANDLE` in `wporg-handle.cjs` became `notAHandle()`, so it is
translated when said.

</details>

<details>
<summary>Screenshots or recording</summary>

Nothing changes in English. In the pseudo-locale the dialog is bracketed
throughout, which the journeys assert.

## Why

The Open a pull request card, its GitHub sign-in, and the errors main
sends it were plain English in a translated window. This is the #625
batch of #622, which needed the catalog in main from #634.

## What changes

- **The card** (`pull-request-destination.jsx`) wraps every string.
Sentences with a link or code in them use `createInterpolateElement`,
with logins, branches and repository names passed in as elements so they
are never read as markup. The failure messages are a function instead of
a module-level constant.
- **Per-project text** in `project-type.cjs` (`cards.*`) is getters,
read when the card renders. Main's refusal with nothing linked used to
splice the work item's label into a sentence; it is now
`cards.prNeedsWorkItem`, one sentence per project type.
- **Main process:** the sign-in errors in `github-auth.cjs` and the pull
request errors in `github-pr.cjs` are wrapped, including the step labels
passed to `failure()`, which the issue did not list. The "Trunk has
moved" message uses `_n`, and a GitHub failure is composed with `%1$s:
%2$s%3$s` so a translator can change the punctuation. GitHub's own
reason and the bracketed diagnostic for GitHub support stay as they are.

Not wrapped, per #622: the pull request body and the default pull
request title, because they leave the app.

## How to test this

The new journeys cover the card in the pseudo-locale on both projects.
Run them from the repository root on either platform:

```
npx playwright test --project=journeys tests/e2e/journeys/i18n.spec.js -g "pull request card"
```

Both fail without this change. The Core journey walks every state #625
lists: signed out, "Not now" and "Show this again", the device code,
signed in with the form and its fold, a `rate-limited` failure, a dry
run, and a pull request opened from a checkout behind trunk. The
Gutenberg one walks signed out, signed in with the fold open, and the
opened pull request, checking the words that are Gutenberg's own.

What the journeys cannot reach is a real GitHub. They stub every
`github:*` handler, so the main-process errors never reach the screen in
them. Unit tests in `github-auth`, `github-pr` and `pr-stage` cover
those strings in the pseudo-locale instead. To see one on screen by hand
(either platform, current head):

1. From the repository root, run `npx electron . --lang=en-XA`.
2. Open a Core site with a linked ticket and an edit, and click **Review
& submit changes**.
3. In **Open a pull request**, click **Sign in with GitHub** and finish
in the browser.
- Expected: every line of the card is accented and in brackets, apart
from your login, your fork's name, the code and the branch.

**What must not have happened:** no English an English speaker sees has
changed. The English journeys in `open-pull-request.spec.js`,
`review-changes.spec.js` and `pr-checkout.spec.js` still pass with their
exact strings.

## Risks and limitations

- The other open batches (#636, #644, #645, #646) also append tests to
the end of `i18n.spec.js`, so whichever merges later resolves that by
keeping both.
- One finding is deferred: `prFailureMessage` decides between five
user-facing strings inside a `.jsx` file the suite cannot load. It
predates this PR (it was the old constant map), so moving it to a `.cjs`
module with a test is a follow-up.

<details>
<summary>Design decisions and alternatives considered</summary>

- **Not stacked on #635.** #622 asks for batches that review on their
own. Now that #635 has merged, its `unwrapped()` scanner change and the
`@wordpress/element` dependency, which this PR also needed, come from
trunk.
- **The textarea placeholder** is three strings joined with a newline. A
single `__()` with `\n` in it is refused by
`@wordpress/i18n-no-collapsible-whitespace`.
- **"Signed in as …"** is wrapped in its own `<span>`, so the sentence
and the **Sign out** button beside it are separate elements, as in #635.

<summary>Review outcome (required — see AGENTS.md)</summary>

2 [fix here] · 1 [follow-up]. Both [fix here] findings are fixed; the
follow-up is deferred (see Risks).

- 🟡 The Gutenberg journey linked no issue, so it never showed the form,
the fold or the loop-back. Fixed: it links one in the record and walks
those states.
- 🔵 No test showed the main-process strings or the stage labels come out
translated. Fixed: pseudo-locale unit tests for the scope refusal, a
composed `failure()`, the plural stale message and `prStageLabel`.
- Style: three dead entries in the journey's `THEIRS` filter were
removed.

- **Review:** completed. Fresh agent context, head `11ef362` / base
`c34aa45`. `npm run lint` clean, `npm test` 2002 pass / 0 fail, i18n and
PR journeys 25 pass.
- **Since review:** `11ef362 → ef457fd`. The only change is the test
fixes above, checked by the authoring session, not re-reviewed by a
fresh context. `src` and `tests` lint clean, unit suite 2005 pass / 0
fail, i18n journeys 12 pass. The review did not run the journeys itself;
it was read-only.
- **After #635 merged:** `ef457fd → 9559a1f` (trunk merged from GitHub)
→ `012fca8` (trunk at `e94f507` merged; `i18n.spec.js` resolved as

## Why

The Terminal and the Logs were plain English in a translated window: the
terminal's help and refusals, every line the setup, update and apply
chains write there, the build watch and dev server lines, the Logs' tabs
and empty-pane notes, and main's own lines from the trunk update, the
pull request switch, the npm runner and the server start. This is the
#627 batch of #622.

## What changes

- **Every line written to the Terminal or a Logs pane** goes through
`__`/`_n`/`sprintf`, with commands, paths, keys and file names passed in
as `%s`. Each line is one or more whole sentences, so the terminal can
show a translated line on its own.
- **Sentences that were spliced together are written whole.** The apply
chain built "The ${noun} is ${verb}" and "${verb} — …" from five verb
and noun pairs; it is now a table of whole sentences per pair
(`applyLines` in `watch-activity.cjs`), the way `applyDoneMessage` in
`confirmations.cjs` works. `applyFinishMessage` used to regex the
English "— open the site to try it out." out of a line; the caller now
passes the line without it. The switch progress (`switch-progress.cjs`),
the setup's `Status: ${phase}`, main's `Update failed during ${stage}`
and the npm "letting go" line each get one sentence per case.
- **Inline markup** (the hints under the terminal, the empty Logs panes)
uses `createInterpolateElement`, with `npm run build`, `help`, `Ctrl+C`,
`package.json`, `src/`, `build/` and `error_log()` passed in as
elements.
- **The dev server's "see Help → Open App Log"** takes the menu item as
`%s`, from the same `__('Open App Log')` the menu uses (left over from
#634).
- **Module-level constants became functions:** `COPY_BUTTON_LABELS`,
`SETUP_END_MESSAGES` and the setup status line move from `index.jsx` to
`confirmations.cjs` as `copyButtonLabel`, `setupEndMessage` and
`setupStatusLine`, where the suite can reach them; `STALE_ASSETS` and
main's `ENGINE_RETRY_NOTICE` become functions too.

110 new strings. Not wrapped, per #622 or because the text is not ours:
Git's own progress phases (`Updating files 3/10`), npm's and the
server's output, the stub `appendNpm` buffer nothing shows, the `42%`
progress figure, and the lines owned by sibling batches
(`SKIP_INSTALL_MESSAGE` and the dirty-tree errors are #626's in #636;
the patch apply lines in main are #628's; the blocked-site errors are
#629's).

## How to test this

The new journeys cover both trays in the pseudo-locale. Run them from
the repository root, on either platform:

```
npx playwright test --project=journeys tests/e2e/journeys/i18n.spec.js -g "Terminal is fully|Logs are fully"
```

Both fail without this change (checked by stashing `src/` and
rebuilding). The Terminal journey opens the tray on a built site, reads
the help printed at start, types `help` and an unknown command, joins
the terminal's rows into whole lines and checks every printed line
starts with `[`, then scans the hints under it. The Logs journey scans
the empty Build watch and Debug.log panes, starts the dev server with
stubbed handlers so the watch starts and the server refuses, and scans
the server's failure line, the watch's start and exit lines and the tab
titles as they change.

What the journeys cannot reach: they stub IPC, so main's lines (trunk
update, PR switch, npm runner, server start) never reach the screen in
them, and neither do the apply, update and setup chains, which need a
real install and build. Unit tests cover those in the pseudo-locale
instead: `watch-activity`, `update-handoff`, `dev-server-command`,
`switch-progress`, `confirmations`, `trunk-update-fetch.integration` and
three in `ipc-wiring` (the server's start failure, the trunk update's
failure lines and the engine retry notice). To see the chains on screen
by hand (either platform, current head):

1. From the repository root, run `npx electron . --lang=en-XA`.
2. Open a built Core site, open the **Terminal** tray and type `help`.
- Expected: every line except the `$` prompt is accented and in
brackets, and the help's descriptions still start in one column.
3. Click **Update to latest trunk** (in its pseudo-localised form) and
let it run.
- Expected: the lines the app writes ("Fetching latest trunk…", "Now on
trunk as of …", "Running npm run build…", "Update complete — …") are
bracketed; Git's and npm's own output is not.

**What must not have happened:** no English an English speaker sees has
changed, apart from the one line break and the one plural named in
Risks. All 132 journeys pass with their exact English strings, including
`terminal.spec.js`, `tray.spec.js`, `logs.spec.js`,
`build-watch.spec.js` and `dev-server.spec.js`.

## Risks and limitations

- Two changes to the English, both forced by the rules: the help's last
paragraph was one sentence broken over two lines with a `\n`, which a
translated string cannot hold, so it is now two sentences on two lines
("…npm run build once." / "Run them here whenever…");
`LONGEST_HELP_LINE` in `terminal.spec.js` follows it. And the switch
progress said "1 files"; with `_n` it says "1 file".
- Merge conflicts with the other open batches: #643, #636 and the
parallel #628 and #629 all append tests to the end of `i18n.spec.js`
(#635 did too; this branch is rebased on it). #636 also adds `import {
__ }` to `use-dev-server.jsx` and `sprintf` to `index.jsx`'s import,
where this branch adds `sprintf` too; those lines will need a one-line
resolution, whichever merges second.
- Main's PR-switch lines and `npmLetGoLine` in `main.js` are covered
only by `npm run i18n:pot` extracting them and lint checking their
comments; the trunk update, server start and engine retry lines have
`ipc-wiring` tests.
- Still English in the terminal during an apply: the lines owned by #628
(main's "Applying …" and the `patch-apply.js` lines) and #626's
`SKIP_INSTALL_MESSAGE` (in #636). They land with those batches.
- The diff is about 870 lines, over the ~800 guideline. Most of it is
the per-case sentence table and tests; it is one tray's worth of strings
and did not split cleanly.
- Review: 3 [fix here], all fixed; 3 [follow-up], deferred (see the
review outcome).

<details>
<summary>Design decisions and alternatives considered</summary>

- **The help's columns.** Each help line is one string, `%s Show this
help text`, with the command padded into `%s`, so every printed line
opens with the translated string's bracket and the descriptions still
line up after the command column. The alternative, a translated
description after an untranslated command, would leave each line
starting in English.
- **The apply sentences as a table**, not a frame like "%1$s but the
build failed": a translation cannot rely on "The patch is applied"
fitting in front of "but". The two `Restored` lines share their English
but have a `_x` context per noun, so a language with gendered
participles can say them differently.
- **"Start the build watch, or run %s in the Terminal."** is its own
sentence after the one saying the site still runs the old assets,
instead of being copied into ten strings.
- **Setup status per phase:** main sends only `cloning` and `done`; each
gets its own line and anything else says "Status update", where it used
to print the code.
- **`Debug.log` and `Debug.log (%d)`** are wrapped so a translator can
name the tab in their language; the file name in sentences is left as
is.

<details>
<summary>Review outcome (required — see AGENTS.md)</summary>

3 [fix here] · 3 [follow-up]. All 3 [fix here] findings are fixed.

- 🟡 `copyButtonLabel`, `setupStatusLine` and `setupEndMessage` were
branches choosing user-facing sentences inside `index.jsx`, which the
suite cannot load. Fixed: moved to `confirmations.cjs` with a test in
English and in the pseudo-locale.
- 🔵 `engineRetryNotice` was made a function so it is translated when
shown, and nothing checked it. Fixed: an `ipc-wiring` test drives the
engine retry in the pseudo-locale.
- 🔵 The Terminal journey dropped any line starting with `[`, so
translated text followed by English would pass. Fixed: each line must be
one bracketed string from its first character to its last.
- Follow-up: the apply flow in the terminal is still partly English
(main's "Applying …" line, `patch-apply.js`, `SKIP_INSTALL_MESSAGE`).
Those belong to #628 and #626 (#636), not this batch.
- Follow-up: the five `compiling` sentences in `applyLines` repeat
`compilingMessage()`'s text, on purpose, so each can be translated
whole; the test now pins all five against `compilingMessage()`.
- Follow-up: `npmLetGoLine` reads `process.platform`, so only one
platform's branch runs in a test. The split was already inline before
this branch; injecting the platform is a separate change.
- One review note was checked and not taken: it said the renderer no
longer imports `switch-progress.cjs`, but `index.jsx` still does, so
that module's header comment stays.

- **Review:** completed. Fresh agent context (Explore subagent given the
diff and the review instructions), head `c7a1ba8` / base `9fd167e`. Lint
clean, `npm test` passing, read-only, so it did not run the journeys.
- **Since review:** `c7a1ba8 → 274bb2d`. The review fixes above, then a
rebase onto trunk `e94f507` after #635 merged (only `i18n.spec.js`
conflicted: both appended tests). Checked by the authoring session, not
re-reviewed by a fresh context: `npm run lint` clean, `npm test` 2044
pass / 0 fail, all 132 journeys pass, `npm run i18n:pot` clean.
- **After CI:** `274bb2d → 6179bd9`. The Terminal journey failed on CI's
macOS runner: it waited for the help's first line, which on that window
had scrolled out of the rows xterm draws, because pseudo-locale lines
are longer and wrap. It now waits for the help's last line. Reproduced
locally at 1024×640 (failed before, passes after). Test-only change,
checked by the authoring session, not re-reviewed: the i18n and terminal
journeys pass (20).

None. Nothing changes on screen in English beyond the help's line break,
and the pseudo-locale journeys are the check for the translated state.

## Why

The ticket card's questions and notices, the merge-in-progress and
legacy-site notices, the deep-link banners, the folder-open failures,
and the input errors for a ticket or issue number were plain English in
a translated window. This is the #629 batch of #622, and needed the
catalog in main from #634.

## What changes

- **Whole sentences, per kind.** Every sentence that spliced in a noun
(`ticket`/`issue`), an English article, or a count is now one string per
kind of work item, with `_n` for counts. This covers the dirty-trunk
question (`ticket-actions.cjs`), the trunk-moved notice and the move's
refusals (`ticket-trunk-notice.cjs`), the changes note
(`changes-note.cjs`), and the carried-work notice in `index.jsx`.
- **The changes note** used to be `lead` / link / `middle` / link /
`end`. It is now one sentence per case with `<review>` and `<discard>`
marked in it, filled in by `createInterpolateElement`.
`DiscardChangesLink` takes its words as children for that.
- **Constants became functions:** `LEGACY_SITE_ERROR` →
`legacySiteError()`, `DISCARD_CONFIRM_MESSAGE` →
`discardConfirmMessage()`, and the merge kinds table →
`kindWords(kind)`. Git commands go in as `%s`; the "resolve the files,
then git add them and run %s" frame and the `<every file the patch
touched…>` placeholder are wrapped.
- **Main process:** the ticket and issue parsers' refusals (main returns
them), the `ticket-branches.js` errors that reach `res.error`, the
rebase handler's three refusals and the dirty-trunk error in `main.js`,
and the editor's exit-code error in `editor-launch.js`.
- `@wordpress/element` becomes a direct dependency, the same line #635
and #643 add.

Not wrapped, per #622: the WIP commit message, which leaves the app.

## How to test this

The new journeys in `tests/e2e/journeys/i18n.spec.js` walk every state
#629 lists, in the pseudo-locale. Run them from the repository root on
either platform:

```
npx playwright test --project=journeys tests/e2e/journeys/i18n.spec.js -g "ticket card's questions|ticket from a link|merge left open|folder will not open"
```

All five fail without this change (checked by putting trunk's `src/`
back and rebuilding). They cover: a refused ticket number; loose edits
on trunk and the question about them; both discard confirmations (read
from `window.confirm`, since Electron's are not Playwright dialogs); the
carried notice and the changes note with its two links; a parked ticket
whose trunk moved; edits saved before a clean start; a deep link with no
site, on a Core site and on a Gutenberg site; a merge left open by a
terminal; a legacy site; and `editor:open` and `dir:show` stubbed to
return each `reason`.

What the journeys cannot reach: the main-process refusals that need a
real Git failure (the move's conflict, "No such branch", a second branch
for the same issue) and the editor's exit code. Unit tests add the
pseudo-locale filter and check those: `ticket-branches.integration`,
`editor-launch`, `trac-ticket`, `github-issue`, `merge-in-progress`,
`legacy-site` and `ticket-trunk-notice`.

To see the card by hand (either platform, current head):

1. From the repository root, run `npx electron . --lang=en-XA`.
2. Open a Core site on trunk, edit `src/wp-login.php`, type a ticket
number in the ticket field and click **Link ticket**.
- Expected: the question and its four buttons are accented and in
brackets.
3. Click the button that takes the edits into the ticket.
- Expected: the carried notice and the changes note under the ticket are
accented and in brackets. The note's two links are accented words inside
its sentence.

**What must not have happened:** no English an English speaker sees has
changed. The full journey suite (129, including `ticket-branches`,
`ticket-rebase`, `merge-in-progress`, `legacy-site`, `gutenberg-site`,
`site-header`, `review-changes` and `trunk-update`) passes with its
exact English strings, and the unit tests that pin whole English
sentences pass unchanged.

## Risks and limitations

- Other open batches also append tests to the end of `i18n.spec.js`:
#643, #635 and #636, and the parallel #627 and #628. Whichever merges
later resolves that by keeping both. This branch carries the same
`unwrapped()` scanner hunk as #643 and #635, byte for byte, so that part
merges cleanly.
- #635 adds an `@wordpress/i18n` require to `changes-note.cjs` on the
same line this branch does, and #636 edits `use-trunk-update.jsx` and
the `@wordpress/i18n` import in `index.jsx`. The `index.jsx` import line
is identical to #636's. The others are small conflicts for whichever
merges second.
- Two English sentences changed in states the app cannot reach:
`rebaseRefusal` with no ticket number used to say "link #the ticket
again" and "which trunk #the ticket started from". They now say "the
ticket". The card only offers the move when a ticket is linked.
- Kept as they were: a few strings still say "ticket" on a Gutenberg
site, as they did before (the merge and legacy notices' "linking
tickets", main's dirty-trunk and rebase errors, "Could not save the
ticket."). Each is wrapped whole, not reworded. Main's rebase errors are
replaced by the card's own per-kind wording before display.
- Not wrapped, because nothing shows them: `ticket-branches.js`'s
refusals to commit on trunk, to switch with uncommitted trunk work
(`dirty-trunk`, asked as a question instead), and its own no-base error
(worded by the card from the code).
- The dirty-trunk question is two whole sentences joined with a space,
as the merge refusal already joins its title and body.

- Review: 1 [fix here] (fixed) and 1 [follow-up] (deferred, below).
- Deferred follow-up: the carried-work notice still picks its plural
inside `index.jsx`, where the unit suite cannot reach it. It was a
ternary there before, and #629 asks for this rewrite at this spot.
Moving it into a `.cjs` helper beside `dirtyTrunkQuestion` would make
both forms testable.

<details>
<summary>Design decisions and alternatives considered</summary>

- **The changes note returns one marked-up string** rather than the five
parts. The parts fixed English word order around the two links; one
sentence with `<review>` and `<discard>` lets a translator move them.
- **The Trac and GitHub hosts and the repository go in as `%s`**, as
#622 asks for product names and keys.
- **The merge restore placeholder** keeps its angle brackets outside the
translated words (`<%s>`), so the pseudo-locale accents the words and a
translator does not have to keep the brackets.
- **The journeys use their own `require` lines** at the end of the file
rather than editing the shared one at the top, so they do not conflict
with the other batches' edits to it.

<details>
<summary>Review outcome (required — see AGENTS.md)</summary>

1 [fix here] · 1 [follow-up]. The [fix here] is fixed; the follow-up is
deferred (see Risks).

- 🔵 Tests: the issue variants of the dirty-trunk question had no test
that pinned them whole. Fixed: `tests/unit/ticket-actions.test.cjs` now
pins each one with an exact `assert.equal`.
- 🔵 Architecture, [follow-up]: the carried-work notice's plural is
decided in `index.jsx`. It was decided there before this PR too.
Deferred.
- The reviewer compared old and new output by hand for every module in
the diff and found no reachable English change. It noted that the
unreachable no-ticket wording of `rebaseRefusal` changed, which is
listed in Risks.

- **Review:** completed. Fresh read-only agent context, head `126b51e` /
base `9fd167e`, all 27 files. Before it: `npm run lint` clean, `npm
test` 2039 pass / 0 fail / 2 skipped, `npm run i18n:pot` clean with
every translator comment in the .pot, full journey suite 129 pass.
- **Since review:** `126b51e → 0bb2fa3` added the test for the [fix
here] finding. Then `0bb2fa3 → 149ff18`, rebased onto trunk at `e94f507`
(base `e94f507`) after #635 merged. The rebase resolved two conflicts:
`changes-note.cjs`'s `@wordpress/i18n` import now takes `_n` alongside
#635's `__` and `sprintf`, and the journeys appended to `i18n.spec.js`
now follow #635's, using trunk's `gitOk` import. The scanner hunk and
the `@wordpress/element` line were already on trunk, so the branch's
copies dropped out. Checked by the authoring session, not re-reviewed by
a fresh context: `npm run lint` clean, `npm test` 2041 pass / 0 fail / 2
skipped, `npm run i18n:pot` clean, full journey suite 135 pass.
