Re-land Cloud machine stale status punctuation

[teamleaderleo]

This re-lands #15900 on the origin branch cloud-sidebar-status-kinds so it can run the UI lane and attach tour frames. It carries the two original commits 7568a7303340c888be52b94c3c09c54f97eff3c7 and 583b156c4b0bd22dce4ea88828e92a580f778c4c, plus the main merge 62e771c80978a9320e1107036dcf794d4317031e. Please close #15900 in favor of this origin PR.

When cached Cloud machines stay visible, the toolbar now separates the sign-in and Pro status from "showing last known" with the same dash used for offline and unavailable states. Each leading clause stays unchanged. This is a copy-only change with no behavior change; status handling, glyphs, actions and truncation are unchanged.

The four keys are machines.offline.stale, machines.listUnavailable.stale, machines.sessionRejected.stale and machines.requiresPro.stale. Only the last two catalog entries change. All nine macOS locales retain their wording and use the separator already present in their offline and unavailable entries. The four Swift defaults use literal dash characters because localize-changes cannot decode the existing Unicode escapes; the offline and unavailable text renders identically.

Validation

The same focused command runs on the separate regression and fix commits:

python3 scripts/ci/dispatch-focused-test.py cmuxTests/MachinesListStatusToolbarRowTests --ref <FULL_SHA> --runner glaeda-std-xcode-26.6

The dispatcher requires a suite selector, so the selector omits the .swift suffix.

• Red at 7568a7303340c888be52b94c3c09c54f97eff3c7: run 36689405426, Test run with 4 tests in 1 suite failed after 0.061 seconds with 2 issues. Both failures are the comma-separated sign-in and Pro stale lines.
• Green at 583b156c4b0bd22dce4ea88828e92a580f778c4c: run 36694512072, Test run with 4 tests in 1 suite passed after 0.062 seconds. The focused dispatch test job was skipped because the selected tests executed inside the build job; the build job passed.
• python3 scripts/verify-local.py: all 6 selected checks ran and passed: Swift syntax, XCStrings structure, localization parity, app-source wiring, test wiring and feature flag policy. The wiring tool executed 13 tests with 0 skipped. No local app build, native test execution or app launch was performed.
• Localization audit: ./scripts/localize-changes --work-file /tmp/cloud-sidebar-status-localization.json imported 16 non-English entries, covering the two changed keys in all nine locales including the updated English entries. The strict validator reports 10 catalogs, 9 locales: 0 parity errors.

Summary by cubic

Re-lands the Cloud machine stale-status punctuation change on the origin branch cloud-sidebar-status-kinds so it can run the UI lane and attach tour frames.

When cached Cloud machines stay visible, the toolbar now separates the sign-in and Pro statuses from "showing last known" with the same em dash used for offline and unavailable states. Only the machines.sessionRejected.stale and machines.requiresPro.stale catalog entries change; all nine macOS locales keep their wording. The Swift defaults now use literal em dashes instead of Unicode escapes.

The toolbar tests resolve expected copy through the same String(localized:defaultValue:) overload the presentation uses, so they stay green on non-English Macs. The resolved-copy comparison pins which catalog key each failure picks; a separate assertion checks every stale line, including offline, for an em or en dash, so a revert to the comma form fails.

^{Written for commit a2e4ee9. Summary will update on new commits.}

Review

A review pass on this re-land compared it against #15900 key by key and found the
change itself faithful and correct. Two things are worth a follow-up push, and one
earlier blocker has already cleared.

Cleared

The catalog conflict is gone: the head is now 141bc33a74 and GitHub reports
MERGEABLE. Worth recording why it appeared, because it will recur. Leo's local
merge=xcstrings-v2 driver resolves Resources/Localizable.xcstrings cleanly, so
git merge-tree exits 0 locally; GitHub has no such driver and falls back to a
text merge, which conflicted. Forcing the text path locally
(-c merge.xcstrings-v2.driver=false) reproduced GitHub exactly and named that
file as the only conflicting path. A clean local merge-tree is therefore not
evidence that GitHub can merge a catalog change.

Worth fixing

1. The new assertion depends on the host locale, and the commit deleted the
   comment that warned about it. cmuxTests/MachinesListStatusToolbarRowTests.swift:52
   asserts stale == "Machine list unavailable — showing last known" against
   presentation.staleTitle, which comes from String(localized:defaultValue:)
   with locale: defaulting to .current. It stays green on the en_US runners
   and reddens on a non-English development Mac. The comment that previously sat
   above it said so in as many words: comparing against the catalog rather than
   English literals keeps a copy edit or a non-en host from reddening the test
   for reasons unrelated to the behavior. No other file under cmuxTests/ asserts
   equality against English localized copy. The stronger assertion is the point of
   this PR, so keep it and pin the locale rather than weaken it.

2. The distinctness assertion is now a tautology. At :62-63,
   lines is built from the test's own hardcoded array rather than from
   MachineListStatusPresentation, so it can only fail if someone edits the test
   data. That assertion is what originally caught three identical sentences in
   production. The three per-case equality checks imply distinctness transitively,
   so no coverage is lost, but the line no longer guards anything and should
   either read from the presentation again or go.

Checked and clean

Sources/Cloud/MachinesListStatusViews.swift is blob-identical between #15900's
head and this one. The test file diff removes no line; it is the original plus
main's MachinesCloudStatusTests, which was already at the merge base. The
vendor/bonsplit gitlink is 83857fa043bd at the PR head, at origin/main, at
the merge base and at the original head, so the pin-revert failure mode did not
fire here. The catalog holds 7394 keys before and after with none added or
dropped; exactly two entries changed content, both carrying all nine locales
before and after, each using the separator its own neighbouring entries already
use, including the en dash for de, the double dash for zh-Hans and the
sentence-final swap for ja. Swift 6 compatibility was confirmed by compiling a
reduced repro of the tuple-array and map(\.1) under -swift-version 6 rather
than by eye. No pbxproj change is needed, and the four changed Swift defaults all
carry U+2014 byte for byte, so the two escape-only edits rightly left their
catalog entries alone.

One thing to know rather than act on: the +6785/-6825 catalog diff is pure
reordering, 6157 of 7394 keys moved, which is inherent to the merge driver
preserving our ordering against a main whose order has moved. Rebuilding the same
two value changes on the merge base's ordering would yield 18 text-merge conflict
hunks instead of 2249. That does not change correctness, and the driver handles
it, but it is why catch-up on catalog branches keeps getting expensive.

Catch-up complete on head ea9c3a9821be906a5b48d6b9b076040f56838154 (merge commit ea9c3a9821be906a5b48d6b9b076040f56838154). GitHub’s cached merge ref was stale, so the PR reported conflicting even though the repository merge was clean; pushing the catch-up merge refreshed it. The focused toolbar test was rerun on this exact head:

• Run 36747990152: Test run with 4 tests in 1 suite passed after 0.057 seconds.

The PR is now mergeable and its CI rollup is green. Auto-merge remains off and this PR has not been merged.

Review

A review subagent read this at 7fce4fb79fd, correctness first, and verified the hasDashSeparator claim against the catalog data rather than taking the PR body's word for it: the four machines.*.stale keys have 36 string units across 9 locales, and all 36 contain U+2014 or U+2013 (32 em, 4 en in German, and zh-Hans doubles the em dash). Zero locales fail, so the assertion holds on a non-English Mac. The comma form these keys used to carry has no em or en dash anywhere, and the only other dashes in these values are U+002D hyphens ("Sign-in", "Cloud-Maschinen"), which the check does not accept, so a revert to the comma form fails in every locale. It also confirmed all four Swift defaultValue literals match their catalog en values character for character, that machines.*.stale are the only four keys in the catalog containing "last known", and that the 14850-line Localizable.xcstrings diff is reordering: 7422 keys on both sides, 0 added, 0 removed, exactly the 2 intended content changes, and the merge ref parses with 0 duplicate-key sites.

The one finding worth acting on: the test file's final form had never compiled anywhere.

Fixed

• The test resolved its expected copy through an overload with no other call site in the repo. String(localized:defaultValue:locale:) appeared only here; all six existing locale: .current call sites in the repo are on String(format:locale:), a different API. .current is that argument's own default, so it bought nothing and added an API surface no lane had compiled. The call now matches MachinesListStatusViews.swift exactly. A local typecheck could not have caught a mistake here either way: Linux Foundation has no String(localized:defaultValue:) at all, so even the form used throughout Sources/ fails to typecheck there.
• Two comments described the file wrongly. The resolved-copy comparisons sit below hasDashSeparator, not above it, and calling them "the strong copy assertion" contradicted the doc comment four lines up that says they pin which key each failure selects, not the words in it.

Left

• hasDashSeparator is position-independent. line.contains would pass a future translation whose leading clause gained an em dash while the separator reverted to a comma. A positional assertion is not portable across these nine locales, whose word order differs, so this is the tradeoff rather than an oversight; it is sufficient for all 36 current values.
• The copy comparison is tautological by construction, resolving the same key, table, bundle and locale as production. The doc comment says so and the separator assertion is the answer to it. Its only non-tautological window is a key missing from the catalog whose defaultValue literal has also drifted from the test's copy of it.
• The re-land did not achieve its stated purpose. This PR moved Align Cloud machine stale status punctuation #15900 to an origin branch so the UI lane could attach tour frames; ui-tests is skipped at this head and no media was produced. For a copy-only change that costs nothing, but the body's reasoning no longer applies.

Evidence

The two focused runs the body cites predate 132d1ee2ff0 and fae6198746e, so they establish the production fix but not the test as it now stands. One focused dispatch of this suite is running at bee203abfa2: run 36760761845. macos / app-host unit tests is skipped on this PR's routed CI, so that dispatch is the only thing that compiles this file, and a compile error in it would redden the app-host test build for every open PR. I will not merge before it reports.

Local gates at bee203abfa2: lint-xcstrings.py (23 catalogs), localization_catalog.py check (10 catalogs, 9 locales, 0 parity errors), sync-test-wiring (clean, 1171 files), verify-local.py --affected origin/main 5/5.
