 ## Unreleased
 
 ### Fixes
+- `scripts/translate-docs/mdx-translator.ts`: new `stripStrayTrailingFence` helper, wired into both `translateMdxPage` and `translateReadme`, drops a stray trailing ` ``` ` line that streamed Sonnet runs of long pages sometimes append. The unmatched fence opens a code block that consumes everything to EOF — including the wrapping `</div>` for RTL READMEs — and surfaces in Mintlify as `Failed to parse page content at path i18n/README.he.md: Expected a closing tag for <div> (6:1-6:16)`. Empirically observed on run 25542951106 (post-streaming-switch #307): `docs/i18n/README.he.md` and `docs/i18n/README.tr.md` both ended with 31 fence-line markers (one stray) instead of the canonical 30; a subsequent rebase against main found `docs/i18n/README.ar.md` regenerated by the auto-translate workflow (#312) with the same bug. The helper detects the odd-count case and removes only the last unmatched fence, preserving every balanced pair before it. Also strips the stray trailing fence from all three affected files in this commit so Mintlify can deploy without a re-translate. Six-case unit test covers balanced-unchanged, no-fence-unchanged, stray-trailing-after-balanced-pair, lone-fence, embedded-non-fence-mid-line, and language-tagged pairs (#313).
 - `scripts/translate-docs/translator.ts`: switch `translateContent` from `anthropic.messages.create(...)` to `anthropic.messages.stream(...).finalMessage()` so large Tier-1 (Sonnet) translations don't hit AWS Bedrock's 300 s synchronous `InvokeModel` ceiling. The LiteLLM proxy at `models.aikin.club` routes `claude-sonnet-4-6` weighted 1:1 across `anthropic/claude-sonnet-4-6` and `bedrock/us.anthropic.claude-sonnet-4-6`; under translate-docs load (4 jobs × 4 in-flight = 16 concurrent) any request that lands on Bedrock and runs >300 s is severed by Bedrock and surfaces to the SDK as `APIConnectionError ("Connection error.")` — exactly the symptom that survived #306 (SDK retry bump) and the platform-side `request_timeout: 300 → 600` lift in `exospherehost/platform#345`. Two consecutive matrix runs post-platform-fix ([25540656053](https://github.com/exospherehost/failproofai/actions/runs/25540656053), [25541614351](https://github.com/exospherehost/failproofai/actions/runs/25541614351)) showed the same deterministic failure cohort: the 4 largest pages (`built-in-policies`, `architecture`, `configuration`, `custom-policies`, plus `README`) failing at ~317 s for in-flight slot 1/2 and ~367 s for slots 3/4 — both below the new 600 s ceiling, so the wall isn't ours. `messages.stream(...).finalMessage()` returns the same `Message` shape so the function's public return type is unchanged; Bedrock falls back to `InvokeModelWithResponseStream` (no 300 s wall) and Anthropic-direct supports streaming for the full 10-minute non-streaming budget. SDK `maxRetries: 5`, per-job `MAX_CONCURRENT: 4`, and the platform `request_timeout: 600 s` ceiling all stay as the correct safety bounds; the actual unblock was on the client-side request shape (#307).
 - `scripts/translate-docs`: bump SDK `maxRetries` from the Anthropic default of 2 to 5 in `translator.ts:getClient` and raise per-job `MAX_CONCURRENT` from 2 to 4 in `cli.ts`, both now env-overridable via `TRANSLATE_MAX_RETRIES` and `TRANSLATE_MAX_CONCURRENT`. The LiteLLM proxy behind `ANTHROPIC_BASE_URL` has been horizontally scaled, so the previous cap of 2 (set in #300 to dodge the gateway's connection-drop cliff at ~2 in flight) now leaves capacity on the floor. The errors that *do* still surface are no longer load-induced — they are per-request transient failures (cold replicas, LB hashing landing on an unhealthy pod, idle-socket TCP resets) where the SDK's default 2-retry budget runs out before the LB can route a retry to a healthy replica, and `Anthropic.APIConnectionError ("Connection error.")` bubbles up. Empirically observed: a `--languages zh --force` re-run (Tier-1 Sonnet, 5 uncached MDX pages) returned 2 successes and 2 `Connection error.` lines under the prior 2/2 setting. Bumping to 5 retries (≈0.5+1+2+4+8 ≈ 15 s of jittered backoff per request, 6 connection attempts total per page) absorbs the transient failures; bumping concurrency to 4 takes back the throughput the prior cap forfeited. CI matrix `max-parallel: 4` is unchanged — the new global ceiling of 4×4 = 16 in flight is still half the failure-mode threshold of 28 from #305 even before accounting for the scale-out, so no workflow change needed (#306).
 - `.github/workflows/translate-docs.yml`: cap the `translate` matrix at `max-parallel: 4` so the 14-language fan-out can't burst past the LiteLLM proxy's connection-drop knee point. The previous `MAX_CONCURRENT = 2` cap in `scripts/translate-docs/cli.ts` (#300) limited per-job concurrency but not cross-job, so under push-to-main the proxy at `ANTHROPIC_BASE_URL` saw up to 14 jobs × 2 = 28 simultaneous requests and returned `APIConnectionError ("Connection error.")` on most of them — surfaced as a workflow-wide failure on run 25532970192 where all 14 matrix jobs errored. With the cap set to 4, the proxy sees at most 8 in-flight; wall-clock cost is bounded since each job is 4–9 minutes and 14 langs in batches of 4 still completes well inside the workflow's existing footprint. Tier-1 (Sonnet, 7 langs sharing one upstream model_name) is the cohort that hit the cliff hardest; Tier-2/3 (Haiku) had headroom and only the single largest doc page consistently errored (#305).
