V-L3-S1: empty placeholder subdirs (dispatch/patterns/recipes/outcomes/...) — populate or remove

[hyperpolymath]

Context (verisimdb-data)

dispatch/, patterns/, recipes/, outcomes/, policy/, health/, well-known/ are mostly empty placeholder directories.

What to do

Either populate (one issue per subdir to make this concrete) or delete the empty placeholders and rebuild as content lands.

Acceptance

• Decision recorded in an ADR
• Empty dirs either gone or have at least a README explaining what goes in them
