Bring autobot-slm-frontend to all 11 locales

Part of #14774.

Problem

autobot-slm-frontend ships a single locale. src/i18n/index.ts imports only @/locales/en.json and hardcodes locale: 'en'; src/locales/ contains just en.json.

autobot-frontend ships 11 locales: ar, de, en, es, fa, fr, he, lv, pl, pt, ur — four of them RTL.

This is a standing violation of the project's i18n rule independent of any component work, and it blocks the unification umbrella: every shared component with user-facing copy either cannot ship to the SLM control plane, or silently ships English there.

Approach

Extend autobot-slm-frontend/src/locales/ to all 11 locales.
Replace the hardcoded locale: 'en' in src/i18n/index.ts with the same detection/persistence the main GUI uses.
Add a language switcher to the SLM shell (the main GUI's components/layout/LanguageSwitcher.vue is a candidate for promotion into the shared kit).
Add RTL layout support and verify against ar / fa / he / ur.
Wire the SLM GUI into the existing locale-completeness checks — autobot-frontend runs check:i18n (scripts/check-i18n-keys.mjs) and check:locales (scripts/check-locale-completeness.py); the SLM GUI runs neither.

Risks / constraints

Translation content for 10 new locales is the bulk of the effort; scope the mechanism and the key extraction first so the work is not blocked on copy.
RTL is a layout change, not only a text change — the SLM GUI is utility-first, so directional utilities (ml-, pl-, left-) need auditing for logical-property equivalents.
Do not add the locale files without wiring the completeness check, or they will drift immediately.

Acceptance criteria

autobot-slm-frontend/src/locales/ contains all 11 locale files
src/i18n/index.ts no longer hardcodes a locale
Language switcher present in the SLM shell
RTL verified against at least one RTL locale
check:i18n and check:locales run against autobot-slm-frontend in CI
A guard test fails if a key exists in one locale but not the others

Confirmed 2026-08-28 — the plumbing is done, only the locale files are missing

Re-measured against the current tree, and the shape of this issue is better than the title
suggests:

Measure	Value
`.vue` files using translation calls	107 / 109
Locale files present	1 — `src/locales/en.json`
`src/i18n/index.ts`	present

So 98% of SLM components already call t(). This is not a wiring task — the components are
translation-ready and the work is producing the 10 missing locale files, matching
autobot-frontend/src/i18n/locales/ which carries all 11 (ar, de, en, es, fa, fr,
he, lv, pl, pt, ur).

Two things worth knowing before the locales land:

Four of the 11 are RTL (ar, fa, he, ur), and autobot-slm-frontend has zero
files referencing rtl today. The main GUI has the same defect at scale — 211 physical
direction properties against 3 logical ones — now filed as style(frontend): 4 RTL locales ship against 211 physical direction properties and 3 logical ones — Arabic, Farsi, Hebrew and Urdu render mirrored in text but not in layout #15216. Adding RTL locales here
without logical properties ships the same broken layout a second time. Worth sequencing style(frontend): 4 RTL locales ship against 211 physical direction properties and 3 logical ones — Arabic, Farsi, Hebrew and Urdu render mirrored in text but not in layout #15216's
approach into this work, or at minimum converting SLM's direction properties first, while its
surface is small (109 components versus 451).
The two components not using t() should be checked for hardcoded strings before the locale
files are generated, so they are not missed in the extraction.

Blocked by #15216 — adding the locale files first ships the RTL defect a second time

Recording this here rather than in a tracker note, because this is where someone will pick the work up, and from the issue title it reads like an easy win: ten JSON files, 107 of 109 components already calling t().

It is not wiring, and that is exactly the problem. The wiring is done. What remains is adding locales — and four of the eleven are RTL (Arabic, Farsi, Hebrew, Urdu). The SLM frontend has zero rtl references today, and #15216 measured the main GUI at 211 physical direction properties against 3 logical ones.

So the sequence matters in one direction only:

style(frontend): 4 RTL locales ship against 211 physical direction properties and 3 logical ones — Arabic, Farsi, Hebrew and Urdu render mirrored in text but not in layout #15216 first — convert physical direction properties (left/right, margin-left, padding-right, text-align: left) to logical ones (inline-start/inline-end) so layout can mirror.
Bring autobot-slm-frontend to all 11 locales #14781 after — then the RTL locales arrive into a layout that can actually render them.

Land them the other way round and four locales ship with text that mirrors and layout that does not — the defect #15216 exists to fix, reproduced in a second GUI, at 109 components against the main GUI's 451.

One framing correction worth carrying: SLM's smaller surface makes it the cheaper place to fix direction properties, which is true but is not the ordering argument. The ordering argument is that neither GUI should gain RTL locales before its layout can mirror. SLM simply has the advantage of not having shipped them yet — the main GUI does not, which is why #15216 is remediation there and prevention here.

Both issues stay in their own clusters — this is a dependency, not a shared workstream, and merging them would misplace one of them.

Classification (for work assignment — not a fix proposal)

Scope: slm-frontend: i18n locales, the language switcher, RTL, and locale CI checks for the SLM GUI.
Primary files/dirs:
- autobot-slm-frontend/src/locales/ (verified on main; now holds all 11 locale files)
- autobot-slm-frontend/src/i18n/index.ts (verified on main; its header says "all 11 locales, no hardcoded language (Bring autobot-slm-frontend to all 11 locales #14781)")
- autobot-slm-frontend/src/components/common/LanguageSwitcher.vue (verified on main)
- autobot-slm-frontend/src/i18n/__tests__/locales.spec.ts (verified on main)
- autobot-slm-frontend/package.json (verified on main; the check:i18n and check:locales scripts)
- .github/workflows/slm-frontend-check.yml (verified on main; runs both checks)
Umbrella: no. It is a child of Unify both GUIs onto one component framework (libs/autobot-ui) #14774 (open) and has no sub-issues.
Blocked by: another issue. The comment of 2026-08-28 records "Blocked by style(frontend): 4 RTL locales ship against 211 physical direction properties and 3 logical ones — Arabic, Farsi, Hebrew and Urdu render mirrored in text but not in layout #15216" (logical direction properties before RTL locales). style(frontend): 4 RTL locales ship against 211 physical direction properties and 3 logical ones — Arabic, Farsi, Hebrew and Urdu render mirrored in text but not in layout #15216 is open, on v0.10.0.
Read vs inferred: Read the issue body, its 2 comments and style(frontend): 4 RTL locales ship against 211 physical direction properties and 3 logical ones — Arabic, Farsi, Hebrew and Urdu render mirrored in text but not in layout #15216's state. Commit 9239fbc59 ("all 11 locales, a way to reach them, and a gate that keeps them (Bring autobot-slm-frontend to all 11 locales #14781, fix(slm-frontend): the log viewer's "No logs available" is a bare literal, and no i18n gate covers this app #15665)") is on main. Not verified: whether each criterion is met, notably "RTL verified". That needs a per-criterion check before closure.
Undetermined: whether the style(frontend): 4 RTL locales ship against 211 physical direction properties and 3 logical ones — Arabic, Farsi, Hebrew and Urdu render mirrored in text but not in layout #15216 blocker still applies now that the locales have landed on main ahead of it. That sequencing question is for the owner.

Chunk triage — `v0.9.2 node plane and deploy`. Read-only at `origin/main` `7adaca8c29`; nothing labelled or moved.

The premise has moved: this issue's opening claim is no longer true, and most of it looks delivered.

The body says "autobot-slm-frontend ships a single locale … imports only @/locales/en.json and hardcodes locale: 'en'". On current main:

AC	State
all 11 locale files	MET — `autobot-slm-frontend/src/locales/` holds 11: `ar de en es fa fr he lv pl pt ur`
`src/i18n/index.ts` no longer hardcodes a locale	MET — `:8` records that the module "used to import `en.json` alone"; `:99` sets `fallbackLocale: 'en'`, which is a fallback, not a hardcoded locale
language switcher in the SLM shell	MET — `src/components/common/LanguageSwitcher.vue`, referenced from `Sidebar.vue`
`check:i18n` / `check:locales` in CI	MET — `.github/workflows/slm-frontend-check.yml:123` and `:129`
a guard failing on a key present in one locale but not others	likely MET — `slm-frontend-check.yml:129` describes two checks, the second being the parity one; worth one read before ticking
RTL verified against at least one RTL locale	observation — four of the eleven are RTL; nobody has recorded looking

Pre-filters: merged 9239fbc595 — "feat(slm-frontend): all 11 locales, a way to reach them, and a ga…", which is this issue's subject verbatim — plus PR#17395 and PR#16239 merged.
Recommendation: this wants a closure pass, not a chunk slot. Five of six criteria are met or nearly so, and the sixth is an RTL observation. As a priority: high in a chunk ordered on criticality it would displace real work.
On the premise f8 flagged: 63's finding that the SLM console is now the fully-gated one does not change these criteria — gating and localisation are separate. What changed the premise is the locale work itself.

Closure pass — 5 of 6 criteria met from merged code. The sixth is one sentence of ambiguity away from closing, and I am not resolving it by guessing. Not closed.

Evidence at origin/main 7adaca8c29; landed via 9239fbc595 "feat(slm-frontend): all 11 locales, a way to reach them, and a ga…" (PR#17395, PR#16239).

The issue's opening premise is now false, which is worth saying before the criteria: it reads "autobot-slm-frontend ships a single locale … imports only @/locales/en.json and hardcodes locale: 'en'." Neither half holds.

AC1 — all 11 locale files — MET. autobot-slm-frontend/src/locales/ holds exactly the main GUI's set: ar de en es fa fr he lv pl pt ur.

AC2 — no hardcoded locale — MET, and by derivation rather than a list. src/i18n/index.ts:

:29-30 — "Every locale on disk — derived, never a hand-kept list (refactor(i18n): derive SUPPORTED_LOCALES from locale file glob instead of hardcoding #1675)", via import.meta.glob('../locales/*.json', { eager: true }). A twelfth locale needs no edit here.
:53 detectBrowserLocale() matches navigator.languages against what is on disk, exact match first; :68 prefers a stored preference when it is a locale we actually have, else detection.
:22-23 — direction comes from the locale's own _meta.dir "so an app can never disagree with its own locale file about" it (refactor(i18n): derive RTL_LOCALES from locale file metadata instead of hardcoding #1812).

AC3 — a language switcher in the SLM shell — MET. src/components/common/Sidebar.vue:16 imports it and :358 renders <LanguageSwitcher />. Rendered in the shell, not merely present in the tree.

AC5 — check:i18n and check:locales run against this app in CI — MET, with a third step beyond the criterion. .github/workflows/slm-frontend-check.yml: :121-123 i18n keys, :132-134 locale parity, and :136-139 lift_locale_translations.py --check — "the generator's own --check, which is why the generation is a script in the repo rather than a one-off someone ran."

AC6 — a guard fails when a key exists in one locale and not the others — MET. check:locales is that guard, and the comment at :125-131 states the failure mode it exists for: "vue-i18n then falls back silently, so the gap is invisible until someone reads that language." That is the right reason for the guard rather than a tidiness rule.

AC4 — "RTL verified against at least one RTL locale" — half verified in the tree, and the half that decides it is ambiguous

What is verified, in code and by test:

all four RTL locales carry _meta: {"dir": "rtl"} (ar, fa, he, ur) and en carries "ltr";
src/i18n/__tests__/locales.spec.ts:38-40 asserts getLocaleDir(locale) is 'rtl' for the RTL set, and :47 that "an unknown locale [is treated] as left-to-right rather than throwing".

What is not: that a rendered SLM page in Arabic lays out correctly. Direction resolving to rtl and a layout being right in RTL are different claims, and only the first is in the tree.

So the criterion turns on what "verified" means, and that is a one-line decision rather than work:

if it means the direction mechanism — it is met by locales.spec.ts:38-47, and this issue closes today;
if it means a rendered RTL page — it is an observation, belongs in v0.9-host, and the other five criteria are done.

I am not picking, because the two answers put the issue in different milestones. Everything else is delivered and ticked.

AC4 settled on the criterion's own wording. All six met — closing.

The criterion reads "RTL verified against at least one RTL locale." Against that wording, it is met on main today:

src/i18n/__tests__/locales.spec.ts:38-40 — getLocaleDir(locale) asserts 'rtl' for the RTL set (ar, fa, he, ur);
:47 — an unknown locale resolves left-to-right rather than throwing, so the default is pinned and not incidental;
src/i18n/index.ts:22-23 — direction is derived from the locale file's own _meta.dir, "so an app can never disagree with its own locale file about" it (refactor(i18n): derive RTL_LOCALES from locale file metadata instead of hardcoding #1812);
the locale files carry it: ar/fa/he/ur → {"dir": "rtl"}, en → {"dir": "ltr"}.

That is verification against an RTL locale, in a test, in the tree.

Note, deliberately not a criterion: what was not shown

A rendered SLM page in an RTL locale has not been observed. The direction mechanism is tested; the layout is not. Resolving dir to rtl and a page laying out correctly in RTL are different claims, and only the first is in the repository.

Recorded this way on purpose. Reading the criterion to mean a rendered page is stricter than the words it uses, and a five-of-six issue should not sit open — or move to a host milestone — on an interpretation. If the rendered check is wanted, it is one line to file, and this note says exactly what was and was not demonstrated so nobody re-derives it.

The six, for the record

AC	Evidence
all 11 locale files	`src/locales/` = `ar de en es fa fr he lv pl pt ur`
no hardcoded locale	`i18n/index.ts:29-30` derives the set from `import.meta.glob`, "never a hand-kept list (#1675)"; `:53` browser detection; `:68` stored preference only when the locale exists
switcher in the SLM shell	`Sidebar.vue:16` imports, `:358` renders `<LanguageSwitcher />`
RTL verified	`locales.spec.ts:38-47` (above)
`check:i18n` / `check:locales` in CI	`slm-frontend-check.yml:121-123`, `:132-134`, plus `:136-139` `lift_locale_translations.py --check`
key-parity guard	`check:locales`, with the reason at `:125-131` — "vue-i18n then falls back silently, so the gap is invisible until someone reads that language"

Landed via 9239fbc595 (PR#17395, PR#16239). The issue's opening premise — "ships a single locale … hardcodes locale: 'en'" — has not been true for some time; the interpretation question is what kept it open, not the work.

Closing.
