Outcome

WeChat QR login now rejects untrusted redirect hosts before contact and authorizes only the exact validated Tencent iLink IDC origin needed by the captured account. OpenClaw and Hermes preserve the existing credential binding and least-privilege REST rules across create and rebuild, including legacy session-only configurations.

Reason

Tencent iLink can redirect a QR-authenticated bot from the bootstrap host to an account-specific idc-[0-9]+.weixin.qq.com origin. NemoClaw followed and persisted that origin, but the sandbox policy still contained only the two static hosts, so bridge traffic could be denied after a successful login.

Related issue

Fixes #10606

Changes

  • Validate redirect and confirmed origins before any redirected request. Reject HTTP, explicit ports, user information, paths, queries, fragments, malformed names, and hosts outside the accepted Tencent iLink grammar.
  • Bound iLink response bodies to 64 KiB, keep request cancellation active through body reads, cancel unread retry and failure bodies, and enforce one whole-login deadline.
  • Redact URL-like polling failures and avoid forwarding response bodies through errors.
  • Materialize the validated WECHAT_BASE_URL at the existing policy-loading boundary by cloning one reviewed endpoint and changing only its exact host.
  • Carry the captured origin through initial create, live policy application, persistence, and rebuild for both agents.
  • Keep the approved static-to-IDC policy transition and legacy config migration in the messaging-channel owner; all other policy drift remains fail-closed.
  • Document the exact-origin policy contract and its credential-binding boundary.

Change-request repair

  • Reject native HTTP redirects on both QR bootstrap and polling requests before another host can be contacted. A loopback-server regression proves the redirected target receives zero requests.

  • Make oversized response cancellation best-effort and non-blocking, including a stream whose cancellation promise never settles.

  • Permit one exact validated IDC endpoint to rotate to one other exact validated IDC endpoint only when the static policy, credential binding, and grants are unchanged. Multiple IDC endpoints and wildcard hosts remain denied.

  • Resolve the messaging agent and channel configuration once before rebuild policy selection, removing the duplicate plan/fallback authority.

  • Consolidate the legacy saved-origin policy delta into rebuild orchestration, removing the one-use exported helper and its separate test owner while retaining fail-closed suffix-confusion coverage.

Verification

  • Exact candidate: 625bf7d4ccd0526eeaefa7d675f7a49a7655ccb9; canonical base: 482714ab20d3e9afd6827046a7851c1d1d7d1831. GitHub reports every published commit signature as verified.
  • npm run validate:pr passed on the committed tree, including repository checks, secret scanning, source-shape checks, codebase growth guardrails, commitlint, and CLI TypeScript.
  • Five focused CLI files passed serially: 96 tests across QR transport, login, channel policy, rebuild handoff, and resolved provider authority for OpenClaw and Hermes.
  • npm run typecheck:cli passed.
  • Exact-head hosted CI run 33466476473 passed on attempt 2. All 12 CLI shards and aggregates are green; only shard 10 was retried after an unrelated five-second inference-profile test timeout.
  • Exact-head growth guardrail run 33466474849, self-hosted PR qualification 33466477898, CodeQL, DCO, commit verification, installer hashes, docs parity, and CodeRabbit passed.
  • The diff contains no secrets, API keys, or credentials.

Review Advisor evidence

  • Exact-head Advisor run 33466474792 completed successfully on attempt 5.
  • Behavior, Code Reduction, Dependency Use, Migration, and Trust passed on attempt 1.
  • Design, Operations, Documentation, and Test Design initially exhausted their built-in HTTP 429 retries. Each failed specialist job was retried once, sequentially; attempts 2 through 5 passed without a broad workflow rerun.
  • All nine final specialist summaries report no finding. Design confirms the channel-owned transition boundary; Migration confirms the legacy session-only OpenClaw and Hermes rebuild path.

Managed-image evidence

  • Exact-head managed-image run 33466476462 passed both Pi architecture builds, the Deep Agents permission regression, direct startup for OpenClaw, Hermes, and Deep Agents Code, all-agent activation, OpenClaw MCP discovery pass 1, and cleanup/credential scanning.
  • MCP discovery pass 2 failed on attempt 1 before NemoClaw behavior because a Cloudflare quick tunnel exited before readiness on all three bounded attempts: job 99729880115.
  • The allowed single-job retry failed before behavior because the consumer searched for attempt-2 managed-pr-contract-* artifacts while the successful producer jobs had only emitted attempt-1 artifacts: job 99731433490.
  • A broad rerun was not requested. This is the still-reproducing failed-job artifact handoff described by Managed-image failed-job rerun loses attempt-scoped base contract #9529, not evidence of a WeChat product failure.

Live messaging E2E evidence

  • Trusted manual PR E2E run 33462179877, correlation 40942bec-0144-4947-b68c-05019276dcf1, candidate 260364e20eb954f9c50fa30b7cb044a6efdc99a3, base/workflow 5fe43c5427da4c79e0f51a72ca999d40e4bfd509.
  • Selectors: messaging-providers and channels-stop-start, mock inference, repository-managed fake messaging credentials, and no staging Brev instance. No messages were sent to real people and no billable resource was provisioned.
  • OpenClaw and messaging-providers stopped during onboarding because the trusted local Dockerfile path still bypassed the BuildKit prebuild and the gateway builder rejected --network. fix(e2e): prebuild candidate sandbox images locally #10725 is merged, but this full path remains incomplete; follow-up: Trusted PR E2E local Dockerfiles still bypass BuildKit prebuild #10737.
  • Hermes onboarding and active-channel validation passed Telegram, Discord, WeChat, Slack, WhatsApp, Teams, and Google Chat. Its stop/rebuild step then failed at the separate live credential-provider authority boundary tracked in Rebuild rejects provider-composed policy after all messaging channels are stopped #10708.
  • All cleanup artifacts reported failures: [].
  • This run did not exercise a live WeChat IDC redirect, did not send a WeChat message, and did not produce a bot-reply receipt. This PR does not claim that evidence.
  • Documentation review: no-docs-needed
  • Documentation evidence: Internal response-reader cleanup only; no user-visible behavior or documentation change.
  • Documentation agent: openai/openai/gpt-5.6-sol
  • Targeted validation: npx vitest run --project cli --no-file-parallelism --maxWorkers=1 src/lib/messaging/channels/wechat/qr.test.ts src/lib/messaging/channels/wechat/login.test.ts src/lib/messaging/channels/policy.test.ts src/lib/onboard/sandbox-create/rebuild-policy-handoff.test.ts src/lib/onboard/sandbox-create/rebuild-policy-provider-authority.test.ts (96 passed); npm run typecheck:cli
  • Broad gate: passed — npm run validate:pr passed against origin/main at 482714a and candidate 625bf7d.

Review notes

  • Product-scope acceptance and accountable maintainer: Support WeChat iLink IDC redirects through sandbox policy #10606 (comment)
  • Upstream main was refreshed to 482714ab20d3e9afd6827046a7851c1d1d7d1831 before the final local validation and SSH push.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 5c07c

This change adds account-specific WeChat origins to sandbox policy, but legacy session-only rebuilds can still abort when no explicit agent is supplied, preventing the WeChat policy from being materialized. Credential and origin persistence also occur in separate steps, creating a bounded interruption/recovery mismatch risk; merge should wait for the rebuild fix and explicit owner acceptance of that lifecycle risk.

Make the fixture support the Hermes policy path.

The fixture only recognizes policy/openclaw.yaml, but channelPolicyPath() selects policy/hermes.yaml for Hermes. The Hermes test therefore returns null before testing policy materialization. Match the agent-specific policy filename or key fixtures by agent.

Redact QR-session failures before returning them.

At Line 150 and Line 239, errorMessage(err) can return URL-bearing transport or HTTP-body details from fetchWechatQrSession. Route both paths through redactWechatLoginError(err) so initialization, refresh, and polling failures use the same diagnostic boundary.

Proposed fix
-    return { kind: "error", message: errorMessage(err) };
+    return { kind: "error", message: redactWechatLoginError(err) };

As per path instructions: “redact URLs and sensitive diagnostics.”

Add exact WeChat endpoint assertions to the remaining host-effect paths.

Initial creation and rebuild coverage exists for both agents. The applier tests only assert the wechat_bridge key, and channel CLI tests do not exercise WeChat. Add assertions for the endpoint, port, enforcement, rules, and credential binding, including failed WeChat re-add restoration.

Request changes on commit under review 274123c5.

Blocking security finding:

  • src/lib/messaging/channels/wechat/qr.ts:77-80,279-283,361-365: reject transport-level redirects before native fetch follows them. The JSON redirect_host validation does not cover HTTP redirects. Native fetch follows 3xx responses by default, so a validated iLink endpoint can redirect the host-side CLI to a loopback, private, link-local, or HTTP destination before NemoClaw validates that destination. I reproduced a 302 to a second loopback server: the second server received one request, and the CLI accepted its QR JSON. Set redirect: "error" for both requests, or validate every Location before contact. Add a native-fetch negative test that proves the redirected target receives no request.

The latest exact-commit PR Review Advisor run also has three unresolved blockers:

  • src/lib/messaging/channels/wechat/qr.ts:199-205 awaits reader.cancel() after the body exceeds 64 KiB. A cancellation promise that does not settle keeps onboarding pending after the request deadline. I reproduced this with a 10 ms timeout.
  • src/lib/messaging/channels/policy.ts:150-158 rejects every live policy that already has an IDC endpoint. mergeReplacementPolicyAccess therefore rejects a valid idc-3.weixin.qq.com to idc-37.weixin.qq.com replacement, contrary to the accepted rebuild and credential-rotation lifecycle.
  • src/lib/onboard/sandbox-create/orchestration.ts:204-224,1546-1548,2200-2215 still supplies both messagingPlan and the already-resolved effectiveMessagingConfig to rebuild policy loading. The fallback configuration takes precedence and leaves two representations at the credential-bearing policy boundary. Pass the single resolved agent and configuration into selectRebuildCreatePolicy.

Focused verification passed 94 tests across the changed QR, login, policy, and rebuild-handoff suites. The two adversarial probes above reproduce behavior that those tests do not cover.

Request changes on latest PR commit 274123c5.

I independently confirmed the blocking findings in Apurv Kumaria's exact-current review: #10692 (review). The transport redirect can bypass NemoClaw's pre-contact origin validation, which materially weakens the host-side network boundary established by #10606. I also confirmed the timeout and policy lifecycle and authority failures described there. Across secrets and credentials, input validation, authorization, dependencies, error handling, transport security, configuration, security testing, and system boundaries, I found no additional blocking issue.

Please resolve that review and add its negative regression cases before re-review.

Move the WeChat materialization into the WeChat channel module.

materializeWechatIlinkEndpoint, WECHAT_BASE_URL_ENV_KEY, WECHAT_POLICY_KEY, and WECHAT_TEMPLATE_HOST place channel-specific rules in the shared policy resolver. A channel-owned resolver keeps the generic loader free of per-channel branching and lets other channels add materialization without editing this file. Keep the dispatch in loadMessagingChannelPolicyPreset generic, for example a map from channelId to a resolver function exported by the channel directory.

As per path instructions, "Channel behavior belongs in manifests, resolvers, hooks, and appliers" and "Keep WeChat-specific behavior in manifests, policy metadata, hooks, and template resolvers; shared onboarding and sandbox actions should orchestrate rather than embed channel rules."

If WECHAT_BASE_URL or the WeChat policy is invalid, the loader throws before loadValidateAndDiscloseChannelPreset can handle its null result.

Derive the fallback policy key and preset name from the manifest registry.

This branch hardcodes "wechat_bridge" and "wechat". The plan-based branch below derives policy keys from getMessagingPolicyKeysByChannel. Two sources of truth now describe the same WeChat policy metadata. If the manifest renames the policy key or the preset, this fallback drifts silently and the rebuild applies the wrong preset or no preset.

Resolve the key and preset for the wechat channel through the manifest registry, keyed by the effective agent, instead of literal strings.

As per path instructions for src/lib/messaging/**: "Transitional tables must be derived from the manifest registry rather than maintained independently."

…eview candidates (#10898)

**Summary:** Treat each pushed commit as a stable review candidate,
batch automated feedback before
repairs, and merge `main` only when the candidate actually requires it.

## Outcome

PR follow-up now treats each pushed commit as one candidate. Contributor
and maintainer agents wait
for required CI and scheduled automated reviews, batch valid repairs,
constrain base integrations,
and reject feedback-driven scope expansion before publishing another
revision.

## Reason

### Main refreshes

This is a cross-team throughput problem, not an individual contributor
habit. In the latest 150 PRs
merged by the core team from August 27 at 05:43 UTC through September 2
at 19:15 UTC, 2026:

- 89 PRs, or 59%, contained at least one explicit merge from `main`.
- Those PRs contained 514 explicit `main` refreshes.
- The average was 3.4 refreshes per PR and the median was 1.

| PR author | PRs | PRs refreshed | `main` refreshes | Average per PR |
Median per PR |
|---|---:|---:|---:|---:|---:|
| `rsliter` | 22 | 19 | 144 | 6.5 | 4 |
| `ericksoa` | 9 | 5 | 82 | 9.1 | 1 |
| `cjagwani` | 3 | 3 | 7 | 2.3 | 1 |
| `cv` | 46 | 14 | 45 | 1.0 | 0 |
| `prekshivyas` | 30 | 26 | 118 | 3.9 | 3 |
| `jyaunches` | 6 | 3 | 3 | 0.5 | 0.5 |
| `senthilr-nv` | 26 | 13 | 32 | 1.2 | 0.5 |
| `apurvvkumaria` | 8 | 6 | 83 | 10.4 | 9.5 |

The largest examples were #9923 with 57 refreshes, #10150 with 26,
#10396 with 22, #10692 with
20, and #10515, #10272, #10275, and #10436 with 19 each.

The average understates how bursty these refreshes are. Forty-six PRs
had at least one run of
consecutive `main` refresh commits. Across the sample, 85 such runs
contained 223 refresh commits.
Eleven PRs had 16 adjacent refresh pairs no more than five minutes
apart. Eighteen had 35 pairs no
more than ten minutes apart.

Examples show both the repeated integrations and the review work they
can invalidate:

- While this PR was being prepared, its skills-only candidate hit
base-owned `fast-uri` advisories
in both sandbox-image builds. Prekshi refreshed it at 20:51 UTC,
creating a 2,154-line merge
commit and restarting Advisor, CI, CodeQL, CodeRabbit, and E2E on a new
head.
- On Apurv's #10436, two consecutive refresh commits landed 10 seconds
apart. Each mapped to a
separate PR Advisor run, and the first run was cancelled when the second
head arrived.
- On #10618, four refresh commits appeared consecutively. The final two
were 2 minutes 20 seconds
apart and produced separate Advisor runs; the earlier run was cancelled
when the later one began.
- On Prekshi's #10692, two consecutive refresh commits were 3 minutes 8
seconds apart, and each
  produced a separate Advisor run.
- On Rebecca's #10150, four refresh commits appeared within 13 minutes
15 seconds. Prekshi authored
three and the automation bot authored one, showing that churn on an
author's PR is not necessarily
  initiated by that author.
- #10308 contained nine consecutive refresh commits. They were spread
across several days, but each
  still replaced the commit under review.

The analysis used complete paginated GitHub GraphQL commit histories. A
`main` refresh is a commit
with multiple parents whose headline names `main`, `origin/main`, or
`upstream/main`. This excludes
same-branch merges. It also excludes rebase-based base updates, so it
measures explicit main merges
rather than every possible base update. Commit timestamps identify
integrations, not push times. The
examples that claim a review restart were separately matched by refresh
SHA to PR Advisor workflow
runs.

### Batching feedback

The current Advisor expands each `synchronize` event into nine
independent specialists and publishes
their separate reviews. CodeRabbit reviews the incremental commit range.
Acting on the first finding
can therefore create another commit while the remaining specialists and
checks are still in flight,
producing overlapping or genuinely new feedback. Complete collection
makes it possible to deduplicate
findings, group them by root cause, and make one repair instead of
serial repair loops.

### Stable review candidates

Each pushed refresh replaces the commit under review and can retrigger
CI, CodeRabbit, and the PR
Advisor. Human review and approval evidence can become stale before that
fanout settles. A base
integration can also import new contracts, fixtures, and generated
identities into the candidate,
which gives incremental reviewers genuinely new material. Treating one
unchanged commit as the
candidate keeps every check and finding attached to the same code until
the complete evaluation is
ready for one repair decision.

## Changes

- Define a stable-candidate protocol in the shared PR follow-up
contract. It waits for each scheduled
Advisor specialist, CodeRabbit, and required CI on one unchanged latest
PR commit, then collects
  each specialist review from its job summary or artifact.
- Deduplicate findings and classify each as candidate-owned or
inherited, in-scope or new scope, and
  blocking or advisory before repairs begin.
- Permit candidate integration with the base only for a conflict, a
required merged dependency, or
  the final merge gate after other findings settle.
- Keep code-changing PRs draft until automated evaluation settles. Reuse
`headRefOid` and non-force
pushes as an optimistic publication guard instead of adding new shared
state.
- Stop implementation repairs that add runtime, lifecycle, security,
deployment, or
  supported-interface scope without a new decision.
- Carry the original objective, accepted scope, deferred scope, and
complete root-cause group into
  every routed repair.
- Fail closed on a failed Advisor specialist or missing artifact until a
NemoClaw maintainer chooses
  a full-workflow rerun or deferral.
- Preserve settled remote review evidence while inspecting local repair
and validator-created diffs,
  with `headRefOid` guarding against competing updates.
- Apply the same sequencing rules to maintainer approval and salvage
workflows.
- Add skill eval cases for refreshes during review, incomplete or failed
Advisor evidence, repair
scope, local publication guards, and premature ready-for-review
requests.

## Verification

- `bash
test/e2e/e2e-cloud-experimental/features/skill/lib/validate_repo_skills.sh`:
passed for all
  29 repository skills.
- Eval JSON parse for all three changed eval files: passed.
- Changed-file prek checks: passed Markdown, JSON, secret scanning, and
growth guardrails.
- Commit hooks: passed pre-commit and commitlint.
- `npm run validate:pr`: passed pre-commit, commitlint, and applicable
pre-push checks against
  canonical `main` at `f427b07d0e01b309983239dd97c989234b18c3c1`.
- `node --experimental-strip-types
tools/pr-review-advisor/render-specialist-matrix.mts`: confirmed
  nine current Advisor specialists.
- Complete Advisor reports were read for every repair candidate from
`4b67754e8` through
`ca2f47c5e`; valid findings were batched by root cause before each
repair.
- The final `ca2f47c5e` set had no valid finding. Eight specialists
reported none; the code-reduction
suggestion was rejected because `TEST-GAPS.md` can change a PR without
entering the merge or
  salvage procedures that retain the proposed prerequisite.
- Diff inspection: no secrets, API keys, or credentials.

## Review notes

- `npm run review:local` did not reach the diff. The local Advisor
sandbox gateway refused its
configuration connection, then cleanup reported `EACCES` on its
temporary context. This is
  environmental unavailable evidence, not a review finding.
- The generic `skill-creator` quick validator could not start because
the host Python environment
lacks PyYAML. The repository's dependency-free validator passed all
skills.
- On `e18ab4253`, both sandbox-image builds failed on advisories against
the base-owned
`fast-uri@3.1.5` lock. The refresh to `main` brought the existing
`3.1.6` remediation; no candidate
  source change was required.
- On `ca2f47c5e`, `test-e2e-sandbox` failed while planning the
base-owned `nim-service.local`
endpoint because it is private or reserved. The blueprint, rejection
code, and E2E script are
  unchanged from the PR base, so no candidate repair or rerun applies.
