Closes #879

Adds Russian as a UI language, listed as Русский in Settings → Language.

  • src/lib/i18n.ru.ts: 959 keys, the same key set as the Korean, Japanese, Chinese and Turkish dictionaries, with identical placeholders. 911 strings come from a Russian translation a native speaker has used and reviewed in daily work; the 48 keys added upstream since then were translated in the same style.
  • src/lib/i18n.ts: ru in LANGUAGE_SETTINGS, LANGUAGE_NAMES, LOCALE_TAGS (ru-RU) and the dictionary map; system detection accepts ru-* tags in browser order.
  • src/lib/voice.ts: Auto dictation reads the translated languages from LANGUAGE_SETTINGS instead of a hardcoded en|ko|ja|zh subset, so a Russian (or Turkish) browser with a matching UI keeps the UI's locale.
  • src/lib/updateNotes.ts: release summaries keep their existing languages; a Russian UI shows the English highlights, else the changelog section.
  • shared/telemetry.ts: the allowlisted language value accepts ru, so a Russian user's snapshot still validates.
  • CONTRIBUTING.md, AGENTS.md, docs/guide.md: the dictionary lists include i18n.ru.ts; every new t("…") key now also needs a Russian entry.

Glossary and style

English Russian
pane панель
workspace рабочее пространство
tab вкладка
session сессия
agent агент
pairing сопряжение
bridge мост
turn ход
Shortcuts Горячие клавиши
  • Buttons are infinitives (Закрепить агента); explanations use polite plural imperatives; errors start with Не удалось.
  • Color theme names (Amber, Dark report, Charcoal, Catppuccin, Lilac, Forest), product names, commands, environment variables and keycaps stay as they are.
  • ё, the Unicode … and «» quotes are used throughout.
  • The runtime has no Russian plural forms, so counts use count-independent wording such as Сообщений: {n}; both English singular and plural keys map to it.

Validation

  • HERDR_TEST_MODE=unit bun test ./src/lib/i18n.test.ts ./src/lib/voice.test.ts ./src/lib/updateNotes.test.ts ./src/lib/settings.test.ts: exit 0, 156 pass, 0 fail. New cases cover RU key parity with every dictionary, preserved theme names and literals, regional detection (ru-RU, RU-BY, ru-KZ, not rue-UA), saved-setting round trip, ru-RU formatting, Auto dictation, English highlight fallback and the telemetry snapshot.
  • bun run typecheck: exit 0.
  • bun run build: exit 0.
  • server/telemetry.test.ts has one Windows-only failure (file mode 0o600) that also fails on unmodified main.

🤖 Generated with Claude Code

Adds src/lib/i18n.ru.ts with every key the other dictionaries carry, lists
Russian as "Русский", detects ru-* browser tags, formats with ru-RU, lets Auto
dictation treat Russian as a translated UI language, and shows English release
highlights for a Russian UI. Telemetry accepts "ru" as a language value.

…appers (#970)

## Problem

`server/herdr/client.ts` exported an untyped `herdrRpc(method: string,
params: Record<string, unknown>)`. Eleven server files called it
directly for four methods (`pane.process_info` x10, `agent.get` x6,
`pane.send_text` x2, `pane.send_keys` x1), each with its own inline
result type. Nothing stopped `{ target }` reaching `pane.process_info`,
which herdr then silently answers for the focused pane (the AGENTS.md
rule was prose only).

## Change

- `server/herdr/methods.ts`: `HerdrMethods`, a `{ [method]: { params;
result } }` map for those four methods. Params and result bodies come
from the generated schema types; `PaneProcessInfoParams`, `AgentTarget`
and `PaneProcessInfo` are now generator roots
(`scripts/generate-protocol-types.ts`, regenerated
`shared/herdr-api.generated.ts`). The map itself is hand-written because
herdr's schema links a method to its params (`request.oneOf`) but not to
its answer: answers are one `ResponseResult.oneOf` told apart only by a
`type` tag (`pane_process_info`, `agent_info`, `ok`).
- `herdrRpc<M extends keyof HerdrMethods>(method, params:
HerdrMethods[M]["params"], …): Promise<HerdrMethods[M]["result"]>` is
the first overload. An untyped fallback overload stays for methods the
map does not list yet. It refuses a typed method name
(`UntypedHerdrMethod<M>` is `never` for one), so
`herdrRpc("pane.process_info", { target })` is a compile error.
`server/herdr/seam.test.ts` pins that with `@ts-expect-error` and checks
the wire params of the new wrappers against a stand-in socket.
- New wrappers: `paneProcessInfo(paneId)` returns one shared
`ProcessInfo` (= generated `PaneProcessInfo`: shell_pid,
foreground_processes with pid/name/argv0/argv) and `agentGet(paneId)`
returns `AgentInfo`. The existing `paneSendText` / `paneSendKeys` now go
through the typed overload. The wrappers call the exported `herdrRpc`
binding, so tests that `spyOn(herdr, "herdrRpc")` keep working.
- Migrated (no open PR touches them): `server/pi.ts`, `server/omp.ts`,
`server/grok-store.ts`, `server/agy-store.ts`, `server/codex.ts` (x3).
Behaviour is unchanged: the same params go on the wire, with the same
default timeout and the same `.catch` / `try` at each call site.
`codex.ts` keeps its old `argv?: string[]` reading through a commented
cast, because the schema allows `argv: null` and that path has never
handled null. Changing that would change behaviour, so it is left for a
separate fix.
- Guard: `server/conventions.test.ts` ("herdr socket") now fails when
server code outside `server/herdr/` uses `herdrRpc`. The message names
the fix ("add a typed wrapper in server/herdr/client.ts; for pane status
use the server/collector.ts listeners") and the allowlist
`HERDR_RPC_ALLOWED`. A stale allowlist entry also fails. The
`events.subscribe` / `subscribeEvents` rules from #949 were already
there; their message now also says where `events.subscribe` lives.
- AGENTS.md: the `pane.process_info` line points at `paneProcessInfo` /
`HerdrMethods` and names the enforcing test. Only that one line changes;
#812, #888 and #894 also edit AGENTS.md.

## Allowlist (`HERDR_RPC_ALLOWED`, migrated in PR B)

| File | Open PRs touching it |
|------|----------------------|
| `server/conversation.ts` | #869 #912 #923 |
| `server/gjc-runtime.ts` | #912 |
| `server/hermes.ts` | #910 |
| `server/omo.ts` | #923 |
| `server/shell-agent.ts` | #885 #923 |

Built from `gh pr list --state open --limit 100 --json number,files` on
2026-10-14.

## Known limits (closed in PR B)

- The export is still named `herdrRpc`. Renaming it to `herdrRpcUnsafe`
would touch about 33 test files and 30 `scripts/` harnesses, several of
them in open PRs (api.contract, gjc.contract, omo.contract,
ui-regression, pending-input…). Tests and `scripts/` QA harnesses are
outside this guard's scope: they drive herdr (`pane.report_agent`,
`workspace.create`, …) and are not part of the bridge seam.
- A call with an explicit result type,
`herdrRpc<Inline>("pane.process_info", …)`, still reaches the untyped
fallback. That is the form the allowlisted files use, and they may not
change here. In server code the source guard closes this gap. The
fallback goes away once the allowlist is empty.

## Validation

- `bun run check fast`: green. A first run had one failure in
`server/portal.test.ts` ("does not treat an arbitrary interpreter as a
Portal script": the process argv read raced and returned undefined).
This change does not touch that file, it passed alone, and the rerun was
fully green.
- `bun run test:integration`: 455 pass, 0 fail, 14 skip in 38 files
(includes the omp, codex, codex-binding, pi, gjc, omo and hermes
contract tests).
- I checked by hand that the guard fails on a new `herdr.herdrRpc` use
in `server/pi.ts`.

## Follow-up: PR B

Once #869, #885, #910, #912 and #923 land: migrate the five allowlisted
files to `paneProcessInfo` / `agentGet` / `paneSendText` /
`paneSendKeys`, empty `HERDR_RPC_ALLOWED`, drop the untyped fallback
overload (or rename it `herdrRpcUnsafe` for tests and scripts), and
consider handling `argv: null` in `codex.ts`.

## Review

Fixed in 290d5f1:

- **Union of typed methods (medium, part of finding 1).** The typed
overload takes `SingleHerdrMethod<M>`, so `herdrRpc(cond ?
"pane.process_info" as const : "agent.get" as const, { target })` no
longer compiles. `seam.test.ts` pins this with a `@ts-expect-error`
line. Checked with tsc: the inferred `herdrRpc("pane.process_info", {
pane_id })` still returns the typed result.
- **Allowlist missed #928 and #859 (medium).** `conventions.test.ts`
adds `HERDR_RPC_PENDING` with `server/gjc-status.ts` (#928) and
`server/index.ts` (#859). Those PRs add a `pane.process_info` call, but
neither file calls herdrRpc on main yet, so the "no longer calls" check
skips them. It would be better for both PRs to switch to
`paneProcessInfo(paneId)`, which is a one-line change in each. After
that, these entries come out.
- **Docs claimed more than the PR delivers (low).** AGENTS.md now says
the guard enforces the rule, not the compiler, and that the allowlisted
and pending files still call herdrRpc. The changelog fragment now says
"no longer compiles without an explicit result type". "PR B" is replaced
with "a follow-up PR that moves these files to the wrappers once their
open PRs land". The fallback docblock in `client.ts` and the
`UntypedHerdrMethod` comment in `methods.ts` list the holes.

Deferred to the follow-up PR that drains `HERDR_RPC_ALLOWED`:

- **Explicit result type and widened string (rest of finding 1).**
`herdrRpc<T>("pane.process_info", { target })` and `herdrRpc(m as
string, { target })` still compile. With an explicit T, the fallback's
`M` stays at `string`, and that cannot be closed while the fallback
shares the name. Closing it means splitting the fallback out as
`herdrRpcUntyped` (or `herdrRpcUnsafe`) and moving about 400 test and
script call sites onto it. It also means converting the
`herdrRpc<T>("pane.process_info" | "agent.get", …)` calls in the five
allowlisted files, which conflicts with their open PRs. `seam.test.ts`
keeps both forms as compiling lines with a comment, so the follow-up can
turn them into `@ts-expect-error`.
- **Error message.** Two overloads are still present, so tsc reports a
bad inferred call such as `{ target }` to pane.process_info as `not
assignable to parameter of type 'never'` instead of naming the wrong
param. That message only gets better with the split.
- **Stale pending entries.** Nothing removes a `HERDR_RPC_PENDING` entry
on its own. If #928 or #859 switches to `paneProcessInfo` or closes, its
entry stays until someone takes it out by hand.
- **Tell the open PRs.** #912, #923, #928, #859 and #910 call
`herdrRpc<T>("pane.process_info", …)`. They should hear about the switch
to `paneProcessInfo` before the split lands. I have not commented on
those PRs.

Checks: `bun run check fast` passed (typecheck, build, 3452 unit tests).
`bun run test:integration` passed (455 pass, 0 fail).

Closing: the app no longer takes new UI languages (see CONTRIBUTING.md, "UI languages", added with #1081). Thank you for the translation work.
