+/**
+ * Warm-startup + parallel-refresh tests for the opencode-plugin config shim.
+ *
+ * Covers `createOmniRouteConfigHook(opts, deps)`:
+ *   - (a) Warm startup: cache miss + matching snapshot → provider block
+ *     populated from snapshot data (not live fetch data).
+ *   - (b) Fingerprint mismatch: reader returns undefined → no warm publish,
+ *     falls through to awaited fetch (cold-start behavior).
+ *   - (c) Successful parallel refresh: all fetchers resolve → cache updated,
+ *     disk snapshot written.
+ *   - (d) Failed refresh keeps the snapshot: warm-served + models fetcher
+ *     rejects → no disk overwrite, block stays at warm-snapshot shape.
+ *   - (e) Parallelism: all six fetchers start concurrently (not sequential).
+ *   - (f) Soft-fail parity under Promise.allSettled: per-endpoint
+ *     fallbacks + logger.warn breadcrumbs preserved.
+ *   - (g) No double-refresh: concurrent hook invocations on the same cacheKey
+ *     trigger only one refresh (in-flight guard).
+ *   - (h) features.diskCache: false disables the warm read entirely.
+ *
+ * Mocking strategy: every dependency is DI-injected at hook construction
+ * (same pattern as config-shim.test.ts). No global monkey-patching.

+feature: 9490

+
+**Warm catalog startup from disk snapshot + parallel refresh** (opencode-plugin): The config-shim hook now reads the last disk snapshot *before* fetching, so the provider registers immediately with the last-known-good catalog (~1-2s vs ~30s on a warm gateway). All six fetchers run concurrently via `Promise.allSettled` instead of sequentially. A failed refresh keeps the snapshot (no overwrite). An in-flight guard prevents concurrent refreshes for the same cache key. The `features.diskCache: false` opt-out disables the warm read entirely.

+#### Forgotten sibling tests report
+
+`npm run check:forgotten-sibling-tests` reuses the import resolver behind the test-impact map.
+For every changed production module, it reports deterministic
+`changed module/symbol -> static consumer -> candidate sibling test` chains when the candidate
+test is absent from the pull-request diff. The Markdown summary and JSON result are retained as
+the `forgotten-sibling-tests` workflow artifact for calibration before any blocking rollout.
+
+Barrel re-exports and dynamic imports are resolution diagnostics only; they never create a
+blocking finding. Reviewed exceptions live in
+`config/quality/forgotten-sibling-allowlist.json`. Each entry must name the consumer and candidate
+test, give a specific rationale, and link a GitHub issue or pull request. Malformed entries fail
+closed. Exceptions cannot suppress a deleted candidate test or a diff that adds `.skip`/`.todo`;
+assertion weakening and other masking remain owned by the independently blocking
+`check:test-masking` gate.

+## 6. Slow-stream throughput watchdog (#9709)
+
+The optional `resilienceSettings.streamRecovery.throughputWatchdog` guard detects
+an upstream that is still sending chunks but producing assistant output below the
+configured useful-output rate. It is deliberately distinct from the idle timeout:
+heartbeats and metadata reset neither timer and do not count as progress. It is also
+distinct from the hard attempt deadline (#9153), which remains an absolute safety
+ceiling regardless of output quality.
+
+The watchdog requires a warm-up period followed by a complete rolling window before
+it can abort. It counts text deltas from Chat Completions and Responses API output
+events (a conservative UTF-8 byte proxy), ignores usage-only and empty events, and
+suspends judgement while tool-call or reasoning events are in flight. It is disabled
+by default and can be enabled with `STREAM_THROUGHPUT_WATCHDOG_ENABLED=true`; the
+window, warm-up, minimum rate, and minimum measurable output are bounded by the
+normal resilience-settings normalization layer.
+
+When enabled, a watchdog abort is applied only to the active upstream attempt. Before
+any client-visible bytes, the existing same-account early-recovery path may reopen
+the attempt. After commit, the stream is never blindly replayed; only the existing
+safe mid-stream continuation contract can stitch a suffix. Finalization remains
+single-shot, so usage accounting and semaphore release are not duplicated.

 ## Quick Start: Connect Your First Provider
 
+### Optional first-run free-provider setup
+
+The first-run wizard offers an explicit **Set up free providers** card. It derives the current
+eligible list from OmniRoute's no-auth provider registry, then lets you review and deselect each
+provider before confirming. OmniRoute shows the provider's caution notice and a link to its site
+so you can review third-party terms, privacy, availability, and rate limits first.
+
+This action is optional: finishing the wizard never creates free-provider connections silently.
+It creates only providers that are still missing, leaves existing customized connections
+untouched, and reports created, already-configured, and failed providers individually. You can
+safely retry only the failures after a partial result.

+### Audio Bridge (`audioBridge.ts`) — Modality Bridge PR-3
+
+Intercepts audio-bearing chat requests before they reach a target that is not
+known to accept audio input. It never reroutes the chat request: audio parts are
+transcribed through the existing OpenAI-compatible multipart endpoint and the
+chosen chat model continues with text transcripts.
+
+Flow:
+
+1. Resolve `supportsAudio` through `getResolvedModelCapabilities()`. Explicit
+   provider-registry metadata wins, then static model metadata, then synced
+   `modalities_input`. A declared input list without `audio` is `false`; no
+   capability evidence remains `null`. Both `false` and `null` activate the
+   conservative bridge, while `true` bypasses it.
+2. Resolve `modalityBridgeAudio*` settings and extract spliceable top-level
+   audio parts from every message through the shared `detectMediaParts()`
+   detector. Supported wire shapes are OpenAI `input_audio`, `audio_url`, and
+   `source.media_type: "audio/*"`. Nested audio is detected for routing but not
+   removed by the splice path. Work is capped by `modalityBridgeAudioMaxClips`;
+   later parts stay untouched.
+3. Honor a configured `provider/model`, or let `selectAudioBridgeModel()` walk
+   `AUDIO_TRANSCRIPTION_PROVIDERS` in stable catalog order and select the first
+   model with a usable active provider credential.
+4. `callAudioTranscription()` converts base64/data-URI audio to a multipart
+   `file`, or downloads a remote `audio_url` through the public-only outbound
+   guard with DNS pinning and a 25 MB bound. It then POSTs the file and selected
+   model to the local `/v1/audio/transcriptions` self-loop, authenticated with
+   `resolveSelfLoopBearer()`. The existing transcription route performs normal
+   credential lookup, cooldown/rate-limit handling, and provider dispatch.
+5. Successful calls replace their parts with `[Audio N]: <transcript>`. Calls
+   run with `Promise.allSettled`: an individual failure preserves that original
+   audio part (#4012 contract). If every call fails and the target is proven
+   `supportsAudio === false`, the parts become
+   `[Audio N]: (unavailable — no STT provider connected)` (#8430 contract). For
+   an unknown target (`null`), an all-failure result stays untouched. A proven
+   text-only target with no usable STT credential receives the same explicit
+   stub without issuing a network call.
+
+Successful transcripts use the process-wide Modality Bridge LRU/TTL cache. The
+key combines the audio reference, the stable `audio-transcription` operation
+label, and selected STT model; failures are never cached. Audio attempts update
+the shared `bridged`, `cacheHits`, `failures`, and `lastUsedAt` counters.
+Transformed responses carry
+`x-omniroute-modality-bridge: audio->text;model=<sttModel>;parts=<n>`; untouched
+requests do not receive an Audio Bridge segment.
+
+Runtime settings are DB-backed and Zod-validated:
+
+| Key                           | Default | Range          |
+| ----------------------------- | ------- | -------------- |

+| `modalityBridgeAudioMaxClips` | `3`     | 1–10           |

+The shared cache remains controlled by `modalityBridgeCacheEnabled`,
