v3.8.42

### ✨ New Features

- **compression (pipeline):** add an honest default-on **inflation guard** to the stacked compression pipeline (T02 / Headroom H1). If the fully-stacked engines produce a body that did not actually shrink — its token count is `>=` the original — the compressed body is discarded and the verbatim original request is sent upstream instead, with a `pipeline-inflation-guard` warning recorded in the compression stats. This is safe by construction (the only fallback is the unmodified original, always a valid payload) and complements the existing opt-in per-step TV1 bail-out, which governs step-to-step advancement rather than the final output. New `open-sse/services/compression/pipelineGuards.ts`; wired at the single `finalizeStackedResult` choke point shared by the sync and async stacked paths. Regression guards (incl. an inflating-engine integration test) in `tests/unit/compression-pipeline-inflation-guard.test.ts`.

- **compression (caveman):** complete the German, French, and Japanese rule packs with the `dedup` (repeated-context collapsing) and `ultra` (abbreviation / terse) categories they were missing — these three languages previously shipped only `context`/`filler`/`structural`, while `en`/`es`/`id`/`pt-BR` had all five. So a de/fr/ja conversation compressed at higher intensities now collapses repeated boilerplate ("wie bereits besprochen" → "Siehe oben.", "comme mentionné précédemment" → "Voir ci-dessus.", "前述のとおり" → "（上記参照）") and abbreviates dense technical vocabulary (`Datenbank`→`DB`, `Authentifizierung`→`Auth`; `base de données`→`BD`, `authentification`→`auth`; `データベース`→`DB`, `アプリケーション`→`app`). Patterns mirror the existing `es` pack and stay ReDoS-safe (bounded literal alternations; the CJK pack uses no `\b` since Japanese has no word boundaries). Regression guard: `tests/unit/caveman-packs-de-fr-ja.test.ts` (packs load + validate + shrink a representative sample). gaps v3.8.42 — T05/C2.

- **compression (caveman):** add a **Chinese (zh / wenyan 文言) input-side rule pack** — the counterpart of the existing output-side `terse-cjk` style. New `rules/zh/{dedup,filler,ultra}.json` collapse repeated context ("如前所述" → "见上。"), drop pleasantries/hedging ("请帮我…/谢谢/我觉得"), strip sentence-final modal particles ("吗/呢/吧"), and abbreviate dense technical terms ("数据库"→"DB", "应用程序"→"app"). Chinese is now auto-detected: `detectCompressionLanguage` distinguishes zh from ja by Han-without-kana (kana is Japanese-exclusive, so a Han-heavy Japanese sentence still resolves to `ja`), and `zh` is listed in `listSupportedCompressionLanguages`. Patterns are ReDoS-safe (bounded literal alternations, no `\b` since CJK has no word boundaries). Regression guard: `tests/unit/caveman-packs-zh-wenyan.test.ts` (packs load + validate + shrink; zh/ja/non-CJK detection). gaps v3.8.42 — T05/C6.

- **compression (RTK):** add **Gradle** and **.NET CLI (`dotnet`)** to the RTK tool-output filter catalog. Tool output for `gradle`/`gradlew` and `dotnet build|test|restore|publish` is now recognized (both by command and by output content) and compressed: Gradle daemon/welcome banners and no-op `> Task … UP-TO-DATE/SKIPPED/FROM-CACHE` lines are dropped while `BUILD SUCCESSFUL/FAILED`, "What went wrong", and stack traces are preserved; the .NET build banner, copyright, and `Determining projects to restore`/`Restored …` chatter are dropped while `Build succeeded/FAILED`, `error CS####`/`warning CS####`, and test summaries are preserved. New builtin filters `engines/rtk/filters/{gradle,dotnet}.json` (with inline tests run by the catalog gate) plus `gradle`/`dotnet` entries in the command detector. Regression guard: `tests/unit/rtk-gradle-dotnet-filters.test.ts`. gaps v3.8.42 — T07/R9.

### 🔧 Bug Fixes

- **providers (chatgpt-web):** fix `502 ChatGPT sentinel failed: Digest method not supported` on the **Electron desktop app**, which made every `chatgpt-web/*` request fail. The sentinel proof-of-work hashed with native `createHash("sha3-512")`, but Electron's Node is built against **BoringSSL, which does not implement the SHA-3 family** (electron/electron#30530), so the digest threw at construction — the provider was unusable on the desktop build (works under plain Node/OpenSSL). The PoW now hashes through a new runtime-portable helper (`open-sse/utils/sha3-512.ts`) that prefers the native digest and transparently falls back to a dependency-free pure-JS Keccak-f[1600] when native SHA-3 is absent. The fallback is validated bit-for-bit against native `createHash("sha3-512")` (300 random inputs) and the published FIPS-202 known-answer vectors. Regression guards in `tests/unit/chatgpt-web-sha3-boringssl-5531.test.ts`. ([#5531](https://github.com/diegosouzapw/OmniRoute/issues/5531))

- **providers (bytez):** fix Bytez key validation ("Provider validation endpoint not supported") and the chat base URL, verified live with a real key. Bytez **is** OpenAI-compatible at `…/models/v2/openai/v1`, but the registry stored the bare `…/models/v2` base, so the validation chat-probe hit `…/models/v2/chat/completions` → `404` → the misleading "endpoint not supported". Two parts: (1) the registry `baseUrl` now carries the full OpenAI-compat chat path (`…/models/v2/openai/v1/chat/completions`); (2) key validation no longer uses a chat probe — a Bytez account only serves models explicitly added to its catalog, so even valid keys 404 on any model id. A dedicated `validateBytezProvider` instead probes the **auth-only** `GET …/models/v2/list/tasks` endpoint (`200` ⇒ valid, `401/403` ⇒ invalid), which is independent of catalog provisioning. Regression guard: `tests/unit/bytez-validation-5422.test.ts`. ([#5422](https://github.com/diegosouzapw/OmniRoute/issues/5422))

- **dashboard (provider add):** two provider-add UX fixes. (1) #5420 — the "Import Models" button now stays hidden for **tool-only providers** (web search / web fetch), not just `*-search` ids: `firecrawl` and `jina-reader` (declared `serviceKinds: ["webFetch"]`) previously showed an Import button that hit the `400 "does not support models listing"` route. A new capability check (`providerLacksModelListing` over the resolved serviceKinds) gates the section without ever hiding an LLM/media provider. (2) #5426 — Coze key validation no longer leaks the raw upstream envelope (`{code,msg,logId,from}`) into the UI; the Coze-shaped error becomes a friendly `Coze rejected the key: <msg> (code <n>)` message (scoped to `provider === "coze"` so no other provider is affected). Regression guards: `tests/unit/model-listing-capability-5420.test.ts`, `tests/unit/coze-validation-error-5426.test.ts`. ([#5420](https://github.com/diegosouzapw/OmniRoute/issues/5420), [#5426](https://github.com/diegosouzapw/OmniRoute/issues/5426))

- **providers (friendliai, novita):** fix two provider registry endpoints that rejected valid keys (verified live with real keys). **FriendliAI** pointed at `…/dedicated/v1/chat/completions`, which `403 Forbidden`s a serverless `flp_*` token — switched to `…/serverless/v1/chat/completions` (+ a serverless `modelsUrl`). **Novita** pointed at the legacy `…/v3/…` base with a typo'd model id `ai-ai/llama-3.1-8b-instruct` (both `404`) — switched to the OpenAI-compatible `…/openai/v1/…` base + the valid `meta-llama/llama-3.1-8b-instruct` id. Regression guard: `tests/unit/provider-endpoints-friendliai-novita.test.ts`. ([#5430](https://github.com/diegosouzapw/OmniRoute/issues/5430), [#5455](https://github.com/diegosouzapw/OmniRoute/issues/5455))

- **providers (muse-spark):** align the Muse Spark Web (Meta AI) cookie copy with the live cookie name. The default session cookie migrated from the retired `abra_sess` to `ecto_1_sess` (`META_AI_DEFAULT_COOKIE`), but the provider form hint and one 401 auth-failure message still told users to paste `abra_sess` — a cookie that no longer exists. Both strings now name `ecto_1_sess`. Regression guard: `tests/unit/muse-spark-cookie-copy-5449.test.ts`. ([#5449](https://github.com/diegosouzapw/OmniRoute/issues/5449))

- **dashboard (provider add):** fix three rough edges in the Add-API-Key / model-import flow reported across the provider-catalog audit. (1) The **Validation Model** and **Account ID** form fields shipped untranslated i18n stub copy (`"Validation Model Id Label"`, `"Account Id Placeholder"`, …) that surfaced verbatim in the modal — replaced with real labels/placeholders/hints in `en.json`. (2) Model import **silently fell back to the cached/local catalog**: the route already returned a `warning` ("API unavailable — using local catalog"), but `useModelImportHandlers` only read `models`/`error` and dropped it, so the user got local models with no indication — the warning is now surfaced as an import log line (new pure helper `extractImportWarning`). (3) The required connection-**name** field defaulted to `""`, which let browser autofill inject garbage (e.g. `wiw`) — it now defaults to `"main"`. Regression guard: `tests/unit/provider-add-ux-i18n-import-warning.test.ts`. ([#5421](https://github.com/diegosouzapw/OmniRoute/issues/5421), [#5428](https://github.com/diegosouzapw/OmniRoute/issues/5428), [#5429](https://github.com/diegosouzapw/OmniRoute/issues/5429), [#5431](https://github.com/diegosouzapw/OmniRoute/issues/5431), [#5435](https://github.com/diegosouzapw/OmniRoute/issues/5435))

- **services (installer):** fix `spawn EINVAL` when installing an embedded service (9Router / CLIProxy) on **Windows + Node.js 24+**. Node 24 stopped letting `child_process.execFile()` run `.cmd` batch files without a shell (nodejs/node#52554), and npm on Windows is `npm.cmd`, so `runNpm()` threw `EINVAL` the moment a user clicked **Install**. `runNpm` now enables `shell` on win32 only. To keep Hard Rule #13 intact under a shell — where the shell, not `execFile`, parses argv — the install `--prefix` (a `DATA_DIR` path that can legitimately contain spaces, e.g. `C:\Users\John Doe\.omniroute\…`) is now passed via the `npm_config_prefix` **environment variable** instead of an argv path, and the user-supplied install `version` is constrained to a dist-tag/semver shape (`SERVICE_VERSION_PATTERN`) at the route boundary so it can never carry shell metacharacters. With the prefix in the environment and the version validated, every remaining argv entry is a static flag. Regression guards: `tests/unit/services/installers/runNpm-shell-5379.test.ts` (+ existing `ninerouter.test.ts` aligned to npm's `npm_config_prefix` env). ([#5379](https://github.com/diegosouzapw/OmniRoute/issues/5379))

- **cli (serve):** restore `dist/tls-options.mjs` to the npm tarball — the opt-in native HTTPS/TLS sidecar (#5361) was copied into the staged `dist/` by the build but then **pruned** by the prepublish allowlist step, so `omniroute serve` crashed on the published 3.8.41 with `ERR_MODULE_NOT_FOUND` (`dist/server-ws.mjs` imports `./tls-options.mjs`). Added `tls-options.mjs` to `APP_STAGING_ALLOWED_EXACT_PATHS` (survives the prune) and `dist/tls-options.mjs` to `PACK_ARTIFACT_REQUIRED_PATHS` (the `check:pack-artifact` gate now fails loudly if it ever vanishes again — same guard pattern as `webdav-handler.mjs`). Regression guards in `tests/unit/pack-artifact-policy.test.ts`. ([#5452](https://github.com/diegosouzapw/OmniRoute/issues/5452) — thanks @KooshaPari for the parallel fix [#5494](https://github.com/diegosouzapw/OmniRoute/pull/5494))

- **dashboard:** fix the **Add Provider / onboarding wizard** button silently doing nothing. The `/dashboard/providers/new` route was a redirect stub (it bounced straight back to `/dashboard/providers`), so every "Add Provider" button and dashboard widget link opened nothing, and the fully-built `ProviderOnboardingWizard` component stayed orphaned (never rendered by any route). The route now renders the wizard directly; auth is enforced centrally by the `(dashboard)` layout, same as the sibling provider routes. Regression guard in `tests/unit/onboarding-wizard-route-5427.test.ts`. ([#5427](https://github.com/diegosouzapw/OmniRoute/issues/5427))

- **db (import):** fix `EBUSY: resource busy or locked` when importing a database on **Windows**. The import route deleted the live `storage.sqlite` + WAL/`-shm`/`-journal` sidecars with a plain `fs.unlinkSync` immediately after `resetDbInstance()`, but Windows releases the SQLite file handle asynchronously after `close()` (mmap / antivirus), so the unlink raced and threw `EBUSY`. The route now deletes via `unlinkFileWithRetry` (EBUSY/EPERM backoff) — the same helper the restore path already uses. Regression guard in `tests/unit/db-import-ebusy-5406.test.ts`. ([#5406](https://github.com/diegosouzapw/OmniRoute/issues/5406), consolidated under [#5161](https://github.com/diegosouzapw/OmniRoute/issues/5161))

- **build:** keep `ioredis` out of the client/CLI bundle — a dast-smoke regression revealed the module was being pulled into browser/Electron client-side chunks; adding it to the `SPAWN_CAPABLE_PREFIXES` leaf excludes it from client bundles while keeping it available on the server path. ([#5546](https://github.com/diegosouzapw/OmniRoute/pull/5546))

- **providers (mimocode):** route per-account traffic through SOCKS5 proxy dispatchers — each mimocode account's requests are now dispatched via its configured SOCKS5 proxy rather than the default direct connection. ([#5521](https://github.com/diegosouzapw/OmniRoute/pull/5521) — thanks @pizzav-xyz)

- **providers:** persist the **Configured** provider filter selection across page reloads — the filter was resetting to "All" on every navigation. ([#5510](https://github.com/diegosouzapw/OmniRoute/pull/5510) — thanks @KooshaPari)

- **providers (chatgpt-web):** support **GPT-5.5 Pro** model handoff — adds the model mapping and handoff routing needed for the GPT-5.5 Pro tier. ([#5536](https://github.com/diegosouzapw/OmniRoute/pull/5536) — thanks @Thinkscape)

- **dashboard:** keep onboarding schemas browser-safe — the schema module imported a server-side `db` reference that crashed the browser bundle; it is now imported only on the server path. ([#5525](https://github.com/diegosouzapw/OmniRoute/pull/5525) — thanks @KooshaPari)

- **routing (bifrost):** add auto-fallback cooldown for bifrost targets — prevents rapid re-selection of a failing bifrost backend within the cooldown window, complementing the existing circuit-breaker mechanism. ([#5519](https://github.com/diegosouzapw/OmniRoute/pull/5519) — thanks @KooshaPari)

- **providers (opencode-plugin):** bump the opencode plugin to **v0.2.0** and wire auto-publish on release so the plugin package tracks OmniRoute releases automatically. ([#5363](https://github.com/diegosouzapw/OmniRoute/pull/5363) — thanks @herjarsa)

- **rate-limit:** normalize queue refresh settings — aligns the queue-refresh interval configuration across rate-limit strategies so stale queues are released on a consistent schedule. ([#5499](https://github.com/diegosouzapw/OmniRoute/pull/5499) — thanks @KooshaPari)

- **fallback:** normalize provider error-rule header extraction — ensures fallback retry decisions correctly read all response headers regardless of casing, fixing cases where a provider's `Retry-After` or custom error header was silently dropped. ([#5473](https://github.com/diegosouzapw/OmniRoute/pull/5473) — thanks @KooshaPari)

- **routing:** gate Claude adaptive-thinking defaults behind the feature flag — prevents the thinking budget from being injected into requests for models that do not support the extended-thinking parameter, avoiding upstream `400` errors on non-thinking Claude variants. ([#5480](https://github.com/diegosouzapw/OmniRoute/pull/5480) — thanks @KooshaPari)

- **ci:** fix post-merge CI regressions introduced by the dead-code sweep — restores test imports and type references broken when the ratchet landed before downstream consumers were updated. ([#5467](https://github.com/diegosouzapw/OmniRoute/pull/5467) — thanks @KooshaPari)

- **sse:** treat terminal stream cancels as complete — an aborted SSE stream was being left in a partial state, causing downstream consumers to wait indefinitely for a final event that would never arrive. ([#5491](https://github.com/diegosouzapw/OmniRoute/pull/5491) — thanks @JxnLexn)

- **api:** fix framing of non-streaming JSON responses — `stream: false` chat-completions responses were returned without correct content-length framing, causing some clients to misparse the response body. ([#5416](https://github.com/diegosouzapw/OmniRoute/pull/5416) — thanks @rdself)

- **dashboard (tests):** protect dynamic dashboard endpoint tests with CSRF validation — the test suite was exercising dashboard API routes without CSRF tokens, masking a coverage gap for those endpoints. ([#5405](https://github.com/diegosouzapw/OmniRoute/pull/5405) — thanks @rdself)

- **providers:** remove the dead **Phind** provider (service shut down) and deduplicate the **HuggingChat** catalog listing that had accumulated a stale duplicate entry. ([#5530](https://github.com/diegosouzapw/OmniRoute/pull/5530) — thanks @backryun)

- **providers (longcat):** correct the LongCat free tier — **LongCat-2.0** is now GA; the one-time 10M-token promo (KYC required) is correctly reflected in the catalog, replacing the stale legacy beta entry. ([#5508](https://github.com/diegosouzapw/OmniRoute/pull/5508) — thanks @backryun)

### 📝 Maintenance

- **dashboard (refactor):** consolidate the duplicate caveman on/off toggle from the compression settings tab onto the single-source panel (T11), eliminating the stale off-sync copy. ([#5524](https://github.com/diegosouzapw/OmniRoute/pull/5524))

- **tests:** add quota guard for Claude-Code identity version lockstep (Phase 2) — asserts that the Claude-Code version reported in quota accounting stays in sync with the deployed version, preventing silent drift. ([#5514](https://github.com/diegosouzapw/OmniRoute/pull/5514))

- **docs:** add relay backend strategy guide documenting supported relay backend types, selection criteria, and configuration patterns. ([#5547](https://github.com/diegosouzapw/OmniRoute/pull/5547))

- **docs:** clarify bifrost relay backend environment variables — documents which env vars control bifrost's relay backend selection and failover behavior. ([#5520](https://github.com/diegosouzapw/OmniRoute/pull/5520) — thanks @KooshaPari)

- **tests:** add relay routing fallback header behavior tests — regression guard asserting that fallback-triggered relay requests carry the correct forwarded headers through the routing layer. ([#5526](https://github.com/diegosouzapw/OmniRoute/pull/5526) — thanks @KooshaPari)

- **ci:** add npm `fetch-retry` configuration and codify the release-freeze protocol (Hard Rule #21) — reduces transient npm registry fetch failures in CI and establishes the documented procedure for freezing releases. ([#5506](https://github.com/diegosouzapw/OmniRoute/pull/5506))

- **deps:** bump 11 production dependencies to their latest compatible versions. ([#5414](https://github.com/diegosouzapw/OmniRoute/pull/5414))

- **deps:** bump Electron from 42.4.1 to 42.5.1 in `/electron`. ([#5413](https://github.com/diegosouzapw/OmniRoute/pull/5413))

- **deps:** bump the development dependency group with 9 updates. ([#5415](https://github.com/diegosouzapw/OmniRoute/pull/5415))

- **maintenance (dead-code):** repo-wide sweep of unused exported symbols, types, and schemas — removes 35 no-longer-referenced exports across cloud-agent, a2a, SSE, memory, quota, skills, gamification, codex, qdrant, playground, provider catalog, and combo modules, reducing the exported API surface and eliminating stale misleading types. ([#5372](https://github.com/diegosouzapw/OmniRoute/pull/5372), [#5373](https://github.com/diegosouzapw/OmniRoute/pull/5373), [#5374](https://github.com/diegosouzapw/OmniRoute/pull/5374), [#5375](https://github.com/diegosouzapw/OmniRoute/pull/5375), [#5376](https://github.com/diegosouzapw/OmniRoute/pull/5376), [#5377](https://github.com/diegosouzapw/OmniRoute/pull/5377), [#5378](https://github.com/diegosouzapw/OmniRoute/pull/5378), [#5380](https://github.com/diegosouzapw/OmniRoute/pull/5380), [#5381](https://github.com/diegosouzapw/OmniRoute/pull/5381), [#5382](https://github.com/diegosouzapw/OmniRoute/pull/5382), [#5383](https://github.com/diegosouzapw/OmniRoute/pull/5383), [#5384](https://github.com/diegosouzapw/OmniRoute/pull/5384), [#5385](https://github.com/diegosouzapw/OmniRoute/pull/5385), [#5386](https://github.com/diegosouzapw/OmniRoute/pull/5386), [#5387](https://github.com/diegosouzapw/OmniRoute/pull/5387), [#5388](https://github.com/diegosouzapw/OmniRoute/pull/5388), [#5389](https://github.com/diegosouzapw/OmniRoute/pull/5389), [#5390](https://github.com/diegosouzapw/OmniRoute/pull/5390), [#5391](https://github.com/diegosouzapw/OmniRoute/pull/5391), [#5392](https://github.com/diegosouzapw/OmniRoute/pull/5392), [#5393](https://github.com/diegosouzapw/OmniRoute/pull/5393), [#5395](https://github.com/diegosouzapw/OmniRoute/pull/5395), [#5396](https://github.com/diegosouzapw/OmniRoute/pull/5396), [#5397](https://github.com/diegosouzapw/OmniRoute/pull/5397), [#5398](https://github.com/diegosouzapw/OmniRoute/pull/5398), [#5399](https://github.com/diegosouzapw/OmniRoute/pull/5399), [#5400](https://github.com/diegosouzapw/OmniRoute/pull/5400), [#5401](https://github.com/diegosouzapw/OmniRoute/pull/5401), [#5402](https://github.com/diegosouzapw/OmniRoute/pull/5402), [#5403](https://github.com/diegosouzapw/OmniRoute/pull/5403), [#5404](https://github.com/diegosouzapw/OmniRoute/pull/5404), [#5463](https://github.com/diegosouzapw/OmniRoute/pull/5463), [#5464](https://github.com/diegosouzapw/OmniRoute/pull/5464), [#5466](https://github.com/diegosouzapw/OmniRoute/pull/5466), [#5468](https://github.com/diegosouzapw/OmniRoute/pull/5468) — thanks @JxnLexn)

- **maintenance (DRY):** DRY consolidation of shared helpers — extracts 17 duplicated utilities into single shared modules: vscode metadata helpers, proxy route handlers, auth zip extractors, combo-builder model options, vscode tokenized-request helpers, quota strategy ranking helpers, recharts donut card, provider-specific validation, batch response formatter, Redis runtime helpers, version-manager request parsing, media-generation route helpers, service install helpers, settings transform schemas, relay stream finalizer, machine-id fallback, and node SQLite adapter. ([#5471](https://github.com/diegosouzapw/OmniRoute/pull/5471), [#5472](https://github.com/diegosouzapw/OmniRoute/pull/5472), [#5475](https://github.com/diegosouzapw/OmniRoute/pull/5475), [#5477](https://github.com/diegosouzapw/OmniRoute/pull/5477), [#5479](https://github.com/diegosouzapw/OmniRoute/pull/5479), [#5482](https://github.com/diegosouzapw/OmniRoute/pull/5482), [#5484](https://github.com/diegosouzapw/OmniRoute/pull/5484), [#5485](https://github.com/diegosouzapw/OmniRoute/pull/5485), [#5488](https://github.com/diegosouzapw/OmniRoute/pull/5488), [#5490](https://github.com/diegosouzapw/OmniRoute/pull/5490), [#5492](https://github.com/diegosouzapw/OmniRoute/pull/5492), [#5493](https://github.com/diegosouzapw/OmniRoute/pull/5493), [#5495](https://github.com/diegosouzapw/OmniRoute/pull/5495), [#5496](https://github.com/diegosouzapw/OmniRoute/pull/5496), [#5497](https://github.com/diegosouzapw/OmniRoute/pull/5497), [#5498](https://github.com/diegosouzapw/OmniRoute/pull/5498), [#5500](https://github.com/diegosouzapw/OmniRoute/pull/5500) — thanks @JxnLexn)
