## Progress log
- 2026-06-07 — Hardening: tree-CRDT orphan reparenting. Concurrent
delete-section + insert-child previously orphaned the child (its parent no
longer a live section) → silently dropped from materialise. Fixed
`crdt-tree-materialize`/`crdt-tree-order` to root any element whose parent is
"" OR not a live section, so content is never lost on concurrent edits. +4
tests (orphan survives, commutes, content preserved, renders at root). Suite
742/742.
- 2026-06-07 — Hardening: regression suite `crdt-blocks` (7 tests) locking that
non-core block types (callout/table/media/section) survive both the flat and
nested-tree CvRDT materialise paths (insert → merge → materialise → render),
