David debugged: Investigated canvas file metadata sync gap causing unlinked lecture source files

After the agent reported a missing linkage:

I have the first clean counts now. Organic is exactly the bad shape you were worried about: 97 file topics persisted, all 97 have lms_content_id, all 97 are unlinked, and there are literally 0 shared_canvas_files rows for the course.

David pushed for clarity on whether this was actually blocking:

is this table even used though? is there stuff in it?

what is the shared_canvas_files table used for? when and where is it populated? and should it have been populated with those Organic rows? or are we inventing a problem where there isnt one?

After understanding the table's role:

okay cool create a plan in a /docs file to implement this fix.

When the plan included phased rollout language:

please dont do a phased rollout over time. we need to do it all now.
