The URL-addressable modals plan shipped in 14 commits. Three places
where the plan's verbatim code didn't survive contact with the codebase
(has_request_context guard, LEFT4ME_ROOT-aware fixture, save-handler
direct-bind) are now documented at the top of the plan, with commit
references for the fixes. Also notes the inserted tasks 8.5/8.5b/9b
and the Task 6 design refinement (close-event single state sink) so a
future re-executor sees the actual shipped pattern.
