Two-milestone plan (M1 edit/delete/publish from feed cards, M2 editable
FilePond photos). Enriched from the ce-brainstorm Product Contract to
implementation-ready, then hardened through a ce-doc-review pass:
- KTD1 committed to patching add-page-by-form's edit branch (the
overwrite_mode:edit create path is unreachable as-is; verified in code)
- owner-username server guards + shared scope-guard helper for both the
edit save path and the new entry-actions delete route (traversal-safe,
page-tree resolution)
- missing edit/delete UX states (loading lock, in-flight guards, focus
management, save-failure preservation) filled in
