Task: Finalize all changes main integration

Identity

Close the project-document ownership gate from reconciled integration commit 0fb1dac245b69966777edf4fc208840ae7af73bb.
Verify source-commit ancestry, the intentionally excluded historical branches, clean worktrees, and fast-forward safety, then advance local main to the finalized candidate.

Make no new product or architecture change. This task exists because the prior integration task necessarily saw foreign task records in its merge-parent history; the fresh base makes the final ownership audit meaningful without rewriting history.
Preserve all source branches, worktrees, untracked audit/report artifacts, and ordinary merge commits. Do not rebase, reset, force-push, delete, or publish.
Keep the two superseded Learning branches outside main and keep the active product boundary at Code, Canvas, and Robot.
Promote only local main; the user did not authorize a remote push.

Read the prior integration task record, canonical current state, ADR-007, ADR-008, decision index, architecture maps/flows, business rules, glossary, commitments, and Integration Gate requirements from candidate 0fb1dac.
Confirmed the prior task already reconciled every completed product source and ran focused/full unit, lint, typecheck, build, and targeted Electron gates.
Other active task worktrees are source/audit histories already classified by the prior task. This final task changes only its own record and local branch placement, so no new semantic overlap remains.
Gate result: Passed. The fresh task's drift check reports only this task-owned record and holds the Integration lock.

Finalized the reconciled integration candidate without altering product code.
Confirmed all five accepted source commits and their ordinary merge commits are ancestors of the candidate, while only the two superseded Learning refs remain outside it.
Advanced local main by fast-forward to this task's final commit; no history was rewritten and no remote push was made.

Fresh check_doc_drift.py ownership check — passed.
Inherited candidate verification at 0fb1dac: typecheck passed; 184 focused tests passed; full unit passed 1,882 with 3 skips plus pressure 1/1; lint had 0 errors and 5 existing warnings; all Vite targets built; targeted Electron E2E passed 12/12.
Source ancestry, git diff --check, candidate cleanliness, main fast-forward relationship, final main equality, and remaining unmerged-branch inventory were checked during promotion.

Remote origin/main remains unchanged. Push only on a separate explicit user request.
Existing production/service/package commitments remain as recorded in canonical project memory; this local merge does not satisfy them.
