Inline comments:
In `@docs-site/src/content/docs/ja/reference/cli/agents.md`:
- Line 167: Update the credential paragraphs in
docs-site/src/content/docs/ja/reference/cli/agents.md lines 167-167,
docs-site/src/content/docs/ko/reference/cli/agents.md lines 173-173,
docs-site/src/content/docs/ru/reference/cli/agents.md lines 208-209, and
docs-site/src/content/docs/zh-cn/reference/cli/agents.md lines 174-174 so only
Pi, OMP, Kimi, and DSH are described as using loopback placeholders; clarify
that Gajae uses OPENCODEX_GAJAE_API_KEY but remains loopback-only and that this
variable does not enable remote Gajae access.
In `@scripts/dsh-rc6-compat-e2e.ts`:
- Around line 157-176: Update toolResponse and its handler to exercise parallel
tool correlation: emit two function_call items with distinct call_id values,
then require both corresponding function_call_output items before returning
finalResponse(). Replace the current broad TOOL_OK-only acceptance with
validation that each expected call is present and matched.
In `@src/integrations/writer-lock.ts`:
- Around line 48-77: Update withIntegrationWriterLock to recover abandoned lock
files: inspect the existing lock’s recorded PID and file modification time, and
take it over when the PID is not alive or the file exceeds a bounded staleness
threshold. Preserve exclusive acquisition for active contenders and retain the
existing deadline behavior when the lock is still valid.
- Around line 79-87: Update the operation/release flow around the lock wrapper
so a release failure from seams.removeFile does not replace an error from
operation(). Preserve the release error when the operation succeeds, but
propagate the original operation error when both fail; add coverage in the
writer-lock tests asserting the original boom error surfaces in the
combined-failure case.
In `@tests/dsh-path-contract.test.ts`:
- Around line 60-61: Update the secret-free assertions in the DSH contract test
to inspect the generated text case-insensitively and reject credential
indicators in both camelCase and snake_case, including the sk- key prefix.
Preserve the existing checks for Bearer tokens and api_key while adding coverage
for apiKey and sk-.
In `@tests/dsh-writer-lock.test.ts`:
- Around line 133-157: Add a focused coordinated-writer test near the existing
DSH tests that creates the DSH home/config context and writes “1\n” to
configPath + ".lock" before calling applyIntegrationCoordinated. Use lock seams
with zero delay and a now implementation that advances beyond the lock deadline,
then assert the call rejects with IntegrationWriterLockBusyError, verifying the
real settings.yaml.lock sibling path and contention behavior without
immediateLock.
In `@tests/integrations-writer.test.ts`:
- Around line 503-504: Update the test around applyIntegration and
disableIntegration to read configPath and assert refreshedModels, including the
refreshed model, immediately after the applyIntegration success assertion and
before disabling. Keep the existing final assertion that disable restores the
original content, and place this focused regression assertion alongside the
existing integration tests.

Maintainer review complete on dd3955c07f6755342de8c38d4d7c432517b58ff6.
I compared the implementation with DeepSeek Harness 0.1.0-rc.6's official home-path, settings-file, llm-pi-ai, and atomic-write contracts, and with the independent rc.6 integration in obra/superpowers#2144. The generated provider shape, DSH_HOME handling, source-preserving YAML ownership, and settings.yaml.lock coordination are compatible. Rejecting relative DSH_HOME is intentionally stricter than upstream and correctly fails closed when OpenCodex and DSH may have different working directories.
Security review: the integration is loopback-only, serializes only the fixed non-secret placeholder, excludes native/OpenAI Direct-account routes (including combo validation), preserves user-authored content outside the owned YAML leaf, and maps lock/path failures without exposing secrets or filesystem paths.
All review threads are resolved, all published checks on the exact head are successful, and the PR records exact-head core, GUI, docs, and real DSH rc.6 E2E verification. I found no remaining blocking issue and no justified follow-up patch to add before merge.

Aligns main, dev, and preview on a single head. preview had diverged bidirectionally and carried no unique work: every commit since merge-base 040f6db has a patch-equivalent on dev/main. It was 12,065 lines behind dev, so the preview npm channel was still shipping the Compatibility Lab on the request path of every install — the exact regression 2.16.0 fixed on latest. The remaining preview-only tree differences were stale rather than new: grok-4.6 effort tiers missing xhigh, google-antigravity defaultModel still on the retired gemini-3.6-flash, and gemini-3.7-flash absent from model metadata. Includes DSH (DeepSeek Harness) first-class client integration (#1665) and the shadow-source interception fix (#1684). Verified on a 16-core linux runner: typecheck clean, 11,719 tests across four shards, 0 failures, core/Lab boundary guard green.
