Task: Finalize integrated main push

Identity

Verify that committed integration payload 161f90d09d6ad1368973b1a85d51059059495223 contains both source merges, the private-network attachment compatibility change, canonical promotion, and passing local gates.
Fetch origin, confirm remote main has not advanced outside the already integrated history, and push local main without force.
Verify the remote branch equals the final local commit, record completion, pass the task-aware documentation gates, and release Integration ownership from a clean worktree.

This task only finalizes the already authorized main push after the predecessor integration payload was committed and its ownership released to establish a clean drift baseline.
The predecessor task record and all source task records are read-only. Record finalization only in this task's own record and canonical integrated-through metadata.
Do not rebase, force-push, deploy, restart services, mutate Kubernetes, read secrets, access ERP, retry live tasks, load the extension, or send external messages.
If origin/main has advanced outside local history, stop and reconcile explicitly before pushing.

Verified that origin/main remained at the already integrated 98282d127c989a7e9ca1d688c9d3d2fadd73e8bc; it was an ancestor of local main, with zero remote-only commits and ten local-only commits.
Pushed local main without force. The remote advanced from 98282d1 to 416d7e8869bb5ea789f7a0c265d87e4c63a294e5, containing both source merges, Chrome extension/runtime 0.5.163, privacy-safe diagnostics, attachment correlation, and trusted-intranet attachment URL support.
Verified git ls-remote and the local remote-tracking ref both resolved origin/main to 416d7e8869bb5ea789f7a0c265d87e4c63a294e5 after the push.
This record supersedes only the predecessor record's final “push pending” note. The predecessor and source task records remain immutable/read-only as required by the Integration Gate.
No force push, deployment, restart, Kubernetes mutation, secret read, ERP access, live-task retry, extension load, or external message occurred.

Predecessor integration payload 161f90d09d6ad1368973b1a85d51059059495223 passed repository hygiene 9/9, TypeScript check, control-plane 135/135, legacy 255/255, build, focused internal-address tests 7/7, shell syntax, project-doc structure, and whitespace checks.
git fetch origin: passed.
git rev-list --left-right --count origin/main...main: 0 10 before push.
git merge-base --is-ancestor origin/main main: passed before push.
git push origin main: passed as a non-force fast-forward.
git ls-remote --heads origin main: matched local/tracking commit 416d7e8869bb5ea789f7a0c265d87e4c63a294e5 after push.
Final check_project_docs.py, task-aware drift, repository hygiene, and git diff --check are rerun after this completion update.

Under separate authorization, build/deploy the integrated control-plane image with DEPLOYMENT_REVISION set, restart it, and verify one real internal WeChat roster attachment through the new diagnostic stages.

None. This task records remote synchronization only; canonical product and architecture facts were already accepted by the predecessor Integration task.
