Migrate the durable session-resilience governance record (Phase 5 orphan-worker reattach deferred-not-planned, EnableOrphanReattach does not yet exist, settled Phase-4 Viewer-default decision) from oldtasks.md into a new "Session-Resilience Epic Scope" entry in docs/DesignDecisions.md, repoint CLAUDE.md and stillpending.md's oldtasks.md references to the new home / tasks.json, and git rm oldtasks.md now that it has no unique content left. Flip TST-29 to Done in the archreview tracking registers. The five untracked root docs-review artifacts (MxAccessGateway-docs-*, MxGatewayClient-docs-*) are absent from this worktree; they must be deleted from the main working tree separately (gitignored, no repo impact).
